How to cut chamotum brick?

Previously, the question of cutting bricks did not arise, because it was simply cut with the help of a pick. But now there are a lot of construction tools that allows cutting blocks quickly and accurately.

During the cut of this building material, a lot of dust is formed, so you need to always use personal protective equipment: a respirator, fabric gloves, plastic glasses. According to safety regulations, all electrical equipment must have grounding.

To get an accurate and even cut, you need to apply the necessary marking to the processed object. The necessary dimensional lines are applied to the plane of brick with a pencil with a pencil with a ruler and a square.

Cutting with a gas tank

A special circular saw of an independent type equipped with a gasoline engine is called a gas tank. This tool has a large mass and size, so for piece cutting of ceramic brick, it is not very convenient. Cutting tool used in a gas tank can be two types: wheels or chains. Both types of equipment are made with diamond spraying.

The saw, equipped with a disk, resembles a corner grinder (only larger). When installing the circuit, the tool is similar to a chainsaw. Due to its power, such a saw is more suitable for cutting openings and niches in brickwork, as well as in dismantling. Benzorezoresis is able to cope with the walls of almost any thickness. A big plus is the equipment of this equipment for a forced water supply system to the cutting area, which eliminates dust.

Cutting brick corner grinder

When performing a small volume of cutting brick, a corner grinder is a good solution. It is recommended to use angular grinding machines with a capacity of 2 kW. But you should not take too powerful, because they are extremely bulky and heavy.

Automatic Servo Clay Brick Strip Cutter Cutting Machine

The most convenient for this are models in which it is possible to use circles with a diameter of 23 cm. The cutting equipment of smaller diameter is also suitable, but using it is not too convenient, t. to. The disk does not pass for the entire thickness of the block. The workpiece will need to be turned over, while the accuracy and quality of processing will suffer, the performance will significantly decrease.

Technically, the method of cutting bricks with a corner grinder does not represent much difficulties. But it is important to hold the tool correctly. It must have a reliable fixation, in which the cutting edge is strictly perpendicular to the processed surface. In an inexperienced person, it is unlikely that you can immediately make an even cut, so you should first practice. It is necessary to take into account the width of the cutting edge and the backlash of the tool.

Experts advise to use a special clamping bed for angular grinder to improve the quality of cutting. In this device, the workpiece is fixed in an individual recess, and the angular grinder is rigidly fixed on the lever. The fixed fastening of the brick block allows you to easily cut it along, across and at any angle. details on

Diamond cutting brick

In order to obtain a flat cut surface without cracks and chips, diamond cutting brick is used. Such work is carried out by corner grinding, but using a special diamond cutting tool. Any work in which such equipment appears are considered a diamond sharp. The difference between these cutting elements is that they have diamond spraying on the working part.

For cutting brick blocks, it is better to use diamond discs, t. to. They ensure the safety of work and have a long service life. Use diamond cutting with a more powerful professional tool is economically impractical.

Manual tile cutter

When there is a need to cut thin pieces of facing brick, you can use a hand tile. It will be convenient when carrying out finishing work, when pieces of brick with non.standard dimensions and angles may be needed.

The use of tile cutters

With forceps you can give a brick an arbitrary figure shape: perform a bevel, rounding, etc. The tool is suitable for thin and painstaking work.

Cutting brick using a special machine

A specialized machine for cutting bricks is effective in case of large.scale work. It allows you to carry out all manipulations as quickly and efficiently as possible. Due to the presence of an irrigation system during processing on such a special machine, a minimum amount of brick dust is thrown into the surrounding air. But this equipment has a fairly high price, so its use for single work is unprofitable.

Some craftsmen make machines with their own hands. To do this, build a structure from a bed (support) and cutting equipment (circular saw, corner grinder). The equipment should be securely fixed and before starting work to control the serviceability.

Features of brick cutting

The working surface of the tool should be very thin and acute

Features of working with blocks at home:

Fragility and brittle material. The chipper and the peorator for cutting are not suitable.
The working surface of the tool should be acute and thin to avoid the appearance of chips.
Before starting work, the subject should be fixed with improvised means.
To prevent dust from scattering, the element must be wetted with water.
During operation, it is necessary to use personal protective equipment to avoid dust and brick fragments into the respiratory system and vision.
The power tool must be reliably grounded.
For the accuracy of the cut, marking is applied to the surface (using a piece of chalk and a square).

At home, you can always find than to cut a brick. There are two types of cutting tools and sawing: manual and electric.

corner grinder (angular grinding machine);
a special machine for cutting building blocks;
electric hacksaw (jigsaw);
laser tool (for cutting openings in a brick wall).

If there is no electricity at the facility, you can use a gas tank to solve production problems.

How and how to cut a brick?

During any construction work associated with brickwork, you can not do without cutting bricks. When building walls, furnaces, fireplaces, with facing and other masonry work, an irregular.shaped unit or non.standard size can be needed.

Varieties of brick

Brick has been used in construction since ancient times. It is distinguished by enviable strength and durability. There are a fairly large number of types of bricks depending on the material from which it is made, as well as on what it is planned to be built (walls, furnaces, etc.).

Red brick

Classic brick, made of special varieties of clay and burned in a stove at high temperature, is called red for its color. It is widely used in various areas of construction and in the construction of individual residential buildings.

The material can be cut at home with several tools that allow this to do this with the production of products that differ in a high level of accuracy. The cutting tool is more often a diamond circle.

The appearance of the final structure largely depends on what to cut.

Hand.shaped facing brick

A distinctive feature of the brick manually is its unusual and attractive appearance. Used for facing work. However, it is quite expensive, therefore, in order to save money, the cutting of a hand.shaped brick is practiced in half along the length of the block. So it will take 2 times less material. Cutting is carried out with a diamond tool.

Facing hollow brick

Hollow brick has inner voids, which can be up to half of its mass. On sale there are products of all kinds of shapes (with ready.made roundings, bevels, etc.), so you need to cut it not so often. If necessary, you can cut the material with any diamond device (corner grinder, saw, etc.).

How and how to cut a brick: an overview of the tool

When conducting masonry work, as well as during the construction of fireplaces, furnaces, when performing facing operations, there is often a need for bricks that have non.standard sizes or shape. That is why any mason or home.made master should know how to cut brick and what devices and mechanisms can help him in resolving this problem.

How to get a non.standard brick or irregular shape

recently, masons and home masters did not think about how to cut a brick for masonry. For many of them, the issue was solved unequivocally. cutting. At first glance, the operation is not very difficult.

Here’s how professionals are described by the order of operations performed during cutting using a combined cell or kirochka:

take a brick in the left hand;
Easily hitting the tool, apply a fishing line for a trimmer of a break on all faces;
sharply hit the cell or kirochka, placing the tool so that it is perpendicular to the verge of brick.

The main disadvantages of this method of forming bricks lie on the surface:

The accuracy of processing leaves much to be desired;
The newly formed line is often uneven, and it is advisable to hide it inside the masonry, which is not always possible;
the impossibility of cutting at a certain angle.

Fortunately, over time, the construction industry was enriched with various tools. They not only facilitate labor, but also allow us to bring convenience and a certain share of aesthetics into it. The emerging tool for cutting bricks provides high accuracy of its processing and high quality of the facial processing.

What tools can be used at the present time, when the question is decided how and what to cut brick at home? Homemade craftsmen and professional masons can use for this:

Review of brick cutting tools:

How brick cutting is carried out

During cutting, in addition to special tools and devices, you will need a square and a construction pencil. In addition, any master must understand and remember that this operation is an extremely dusty. The use of a respirator and protective glasses during the work is an urgent, even vital necessity.

To ensure the accuracy of sawing brick, it is desirable to make the necessary marking before the sharp. To do this, a fishing line for a trimmer saw is applied using a pencil. The cut itself is made next to the line. If cutting is strictly along the line, then the brick can turn out to be smaller than necessary.

The question of how and how to cut a brick is often solved based on the upcoming volume of work.

Using a corner grinding machine

Cutting brick with an angular grinder (angular grinding machine. corner grinding) is most often carried out during small.scale production. To do this, you need to choose a tool capable of working with a circle of 230 mm. If the circle has a smaller diameter, then cut the brick on its entire thickness will not be able to. Therefore, it will have to be turned over, and this reduces both performance and quality of work.

The angular grinder used should have a power of at least 2 kW. Too powerful tool in work is inconvenient because it has large size and weight.

In addition, working with a corner grinder, you should choose the right disk for cutting brick. There are two main types used to perform these operations:

The only advantage of the abrasive disk is its apparent cheapness. It really is only apparent, since such a disc wears out quite quickly and requires frequent replacement. In addition, the use of an abrasive disk is quite dangerous, since it is easily deformed and destroyed.

Diamond disk is more preferable to cutting. Its basis is strong steel. The disk is reliable, much less dangerous, characterized by the constancy of its diameter in the course of work. At the same time, diamond discs are of several types:

ordinary with a solid edge. Such discs are cheaper than the rest and provide high cut quality. But they are very warm and wear out faster than others;
segmented, cutting edge of which is divided into separate sections using radial cuts. With this design, the cutting area is well ventilated and the sludge is well diverted. Segment discs are convenient with dry cutting;
turbocharged disks. This edge is equipped with a gear surface, has high rigidity and strength. Such discs are most durable and convenient with wet and dry cutting.

To ensure the better quality of the sawdust using a corner grinder, it is recommended to use a special device called the bed for angular grind. With the help of such a bed, an angular grinder can be fixed on a special lever, and a brick in a special device provided for this. The bed allows you to make not only straight cuts, but also cut the brick at an angle.

Cutting with a gas tank

Benzorezer or, in other words, a special saw when cutting piece brick is quite uncomfortable, since the device is quite significant and large.

If a disk is installed in a gas tank, then it resembles an angular grinder that has a powerful gasoline engine. If a chain is used in a gas tank as a cutting tool, then it looks very similar to a chainsaw. The chain of a gasoline cutter, like a circle, is made in accordance with special technology and is equipped with a diamond coating.

A saw for cutting bricks is especially convenient when arranging openings in brick walls or when they are demolished. The great advantage of such saws is that almost every of them has a forced water supply. This fact allows us to provide greater comfort with such dusty work as a cut of brick.

Cutting brick using a special machine

A brick cutting machine is a device that includes:

strong metal frame;
drive with a drive;
diamond disk;
workpiece mounting system;
irrigation system that allows you to almost completely eliminate the formation of dust.

Hand tool

Most often, manual tools are used when conducting minor masonry work or repairs. The main devices are a building chisel or a chirus, a regular hammer (not a kiyanka). Mandatory hand protection.

Brick cutting in the sand

To cut the product, you need to scratch a flat fishing line for a cutting trimmer on all faces. Its depth should be up to 5 mm. After that, the chisel or kirochka must be installed in the groove and thoroughly hit the tool. Harsh fixation is not needed. Brick can be put on a soft surface or pick up so that the separated part does not have a support.

How brick cutting is carried out

When processing the data of building materials, a pencil and corner are required, in addition to the main cutting element. It should be noted that this procedure is accompanied by the formation of a significant amount of dust, so it is extremely important to use personal protective equipment. The respiratory tract should be protected by a respiratory mask, eyes with protective glasses, and hands with gloves.

For a more accurate cutting of building materials, it is necessary to first apply the marking to its surface. For this, a construction pencil is used. Now you can start cutting, and you need to do this not along the line itself, but near it, otherwise, a fragment of bricks will not turn out as required as required.

Silicate brick.

Silicate brick, unlike ceramic, is quite young building material, but managed to quickly gain a foothold in the building materials market. Thanks to its relatively low cost, it is often used at the construction sites of urban construction as an independent building material or in combination with others. The undoubted plus of silicate brick in front of ceramic consists in its increased soundproofing characteristics, which is important in the construction of inter.apartment or interior walls. Silicate brick is used for the construction of load.bearing walls and partitions above the basement in rooms with reduced humidity. It must be remembered that the water resistance of silicate brick is lower than that of ceramic. Great for the construction of fences. They do not make foundations and stoves from it.

Special equipment

Under special equipment, I think machines intended for even cut. They for the most part become homemade. Their meaning is to fix the corner grinding of a machine at an important angle with the possibility of a free vertical move.

We also need to fix the brick itself, because this is how we can achieve a very even cut in the right place. If you do not fix the stone properly, get ready for the fact that it will fly out and damage something that can be located around the installation.

Production of blanks

Cutting a brick with a corner grinder is necessary in small.scale production. Line or brigades of builders to buy specialized equipment unprofitable and have to use more universal.

For cutting bricks with a corner grinder, you need a power tool for a circle with a diameter of 230 mm.

For cutting bricks with a corner grinder, it is better to use diamond discs.

When using a corner grinder under the 180th circle, cutting a brick to the full thickness will not work, you will have to turn it over, which significantly reduces the performance and convenience of work, and you will not get an even cut over two passes.

Corner grinding grinding for cutting bricks should choose a fairly powerful. For a long tool for the tool and a comfortable speed of work, you need an angular grinder with a capacity of about 2 kW or more. Too powerful cars are not desirable, t. to. They, as a rule, have a sufficiently large mass and dimensions, which contributes to rapid fatigue when working with corner grinders and reduces the overall comfort of operation. It is convenient to finalize surfaces with a 125 mm angular grinder.

During the use of corner grinder, do not forget about safety precautions. Be sure to put on the goggles.

There are two main types of stone circles: abrasive and diamond. Perhaps the only advantage of the standard abrasive circle can be considered its relative cheapness. Cheapness is precisely relative, t. to. ordinary abrasive circles are subject to rapid wear and are subject to frequent replacement. They are also inconvenient in work, since when stinging such a circle, its diameter is constantly reduced, and it cuts to full depth only at the very beginning of use. Abrasive circles of different manufacturers can differ greatly in quality and service life. As a rule, a good abrasive circle on stone has double reinforcement and a thickness of 2.5-3 mm. It is dangerous to work with an abrasive circle, t. to. It is more susceptible to deformations and destruction.

The diamond circle is preferable, it retains a constant diameter during operation. One diamond circle of good quality can survive dozens of ordinary abrasive circles. The diamond disk has a strong steel base, as a result of which the probability of its destruction is negligible.

Kolka and Teska Brick: a. the right speaker across; b. irregular speaker across; B. Kolka along; g. working position with Teske; D. working position with Kolka.

There are several types of such circles. The simplest circles with a continuous edge are cheaper than the rest, but have significant disadvantages. In the process, they are very hot, which can cause emergency discharge of disk. To avoid this, it is necessary to arrange breaks in work. The service life of such discs is the lowest. The advantage of the continuous edge of the disk is the high quality of the cut surface without bullying and dyeing.

The most common diamond circles are segment. Their cutting edge is divided by radial cuts into separate sections. This design allows you to effectively remove the sludge and ventilate the cutting area. This is a good choice to cut a brick with a corner grinder. They are usually used for dry cutting. When water supply, segment grooves are clogged with wet cutting products, which worsens the properties of the disk.

The best option will still be a turbocharged disk. It has a toothed surface that gives the disc of higher strength and rigidity. The location of the teeth on the edge of the disk in a spiral creates the effect of the centrifugal pump, which is the best possible to divert wet or dry sludge. Discs of this design are most durable and cut brick and masonry stones of any type.

Before cutting a brick with a corner grinder, you must first mark. This is done by a building pencil and a square. It is necessary to take into account the thickness of the disk and the backlash on the spindle of the corner grinder. If you draw a fishing line for a trimmer simply in the right size, most likely you will not succeed. Cut brick will be shorter than the required size by 1.5-2 mm.

For cutting bricks, it is best to use diamond discs with a turbocharged edge. They are well suited for working with particularly durable materials.

Cutting a brick with a corner grinder is quite difficult, and this requires a certain skill, t. to. The disk must be strictly vertically and not deviate until the process is completed. In an inexperienced hand, the tool “walks” by weight. If you have to cut a brick for the first time with a corner grinder, it is better to first try your hand and practice. Inexpensive brick for draft masonry is suitable, or find several former. You can also make a preliminary cut with a depth of a few mm. It helps a little to centr with the main cutting and is better noticeable in conditions when the fishing line for a trimmer from a pencil quickly covers with a slope. Under the brick that you cut, put one more. So you will save a disk, and keeping the tool will be easier.

If it so happened that at the moment there is no large corner grinder, but you need to cut a brick, you can make a cut around the perimeter with a small corner grinder. Then it remains only to carefully beat off the excess and clean the cut with the same machine.

Sometimes in order to exclude the displacement of the workpiece during cutting, the brick is clamped in special devices, where the brick is fixed from vertical and lateral displacements.

The device of the openings

Cutting bricks with corner grinders is necessary when arranging openings in the walls. If the brick is not on the rib, then the diameter of the circle is probably not enough to perform work in one pass. In this case, mark the opening on the wall on one side and in the corners we make through the through holes, which will allow you to move the marking without displacement to the opposite side.

Types of chamotis brick

Fireproof brick in composition is divided into 4 types:

Decorative fireclay brick

Fireproof brick made of chargen clay is expensive, decorative tiles are released to replace it. It imitates an expressive soft relief of the old manual molding material, has saturated flowers of burned clay. This universal brick is used for external and interior wall decoration, door, window openings, corners, arches, facades. The decorativeness of the masonry is achieved due to the variety of geometric shapes. This brick is thin, during decoration the area of the room does not decrease, and the variety of colors will help create a unique atmosphere.

How to make a tandoor from brick on your own.

Corner grinder (cutting circle by ceramics).
A container for kneading a concrete solution.
Master OK.
Tandoor laying.
Brush for paint.
Construction level.

Base under the stove tandoor.

You need to install the furnace on the foundation, the best option is to make a pillow of crushed stone and sand and cast a plate of 1 x 1 meter in size, 10 cm deep. The shape of the plate can be any.

Brick laying of the tandoor.

What brick can be used for a tandoor? Do not use silicate or red brick, it is not intended for furnaces and is gradually destroyed under the influence of high temperatures. It is optimal to build a tandoor stove from refractory chamotis brick, such a stove will be reliable and will last a long time.

Before starting brickwork, you need to take care of waterproofing, so that the brick does not pull moisture from the foundation to lay a piece of roofing material or similar material on it.

On the basis of we need to outline a circle with a diameter of 750 mm under the stove itself.

We need 16 bricks for laying the bottom of the furnace, focusing on the circle, try on bricks and lay out the bottom of the furnace, cut off the brick with a corner grinder with a cutting circle. After trying and fitting bricks, we put them on the masonry chimney mixture.

Knead the mixture for laying the tandoor in small portions, as the brick is laid, you need to constantly adjust, cut it with a trim circle, a large amount of solution will quickly grasp and become unusable.

We lay a well.mixed mixture with an even layer on the roofing material, lay the already prepared cut brick, the seams between the bricks are also filled with the mixture. As the brick laying is checked by the construction level, everything should be in the strictly horizontal plane.

The bottom of the tandoor is ready, now let him stand for a day so that the solution gains its original strength.

In the meantime, we will make a tandoor brickwork, which will greatly facilitate the process of masonry bricks.

Height. 1000 mm.
Lower width. 300 mm.
Two of the upper 250 and 200 mm.
Step the interwex.

In fact, when laying bricks, we get an internal diameter of the base of the furnace 600 mm, the upper part is 400 mm.

We lay out the first row of brick, the brick is put on a stand, to fix the structure, fasten it around the circumference with a wire, the wire can then be left then it will still be covered with plaster.

We lay out the second and third rows, the bricks need to be cut under the wedge with a corner grinder, laid the cut bricks through one, alternating with the whole.

After laying the final third row, we cover our tandoor from the outside with the solution, the thickness of the plaster should be at least 10 mm, otherwise the plaster when heated will crack and quickly fall off, the stove is unnecessary inside the stove unnecessarily.

The upper edge of the furnace must also be plastered.

Now the stoves need to stand for three days to gain sufficient strength, for this period it is advisable to cover it with a plastic film so that the moisture does not evaporate quickly.

The final stage. we cover the stove from the outside with water.based paint for external work.

The stove inside you need to carefully clean with a brush and thoroughly threw it out, then you can already cook in it.

Another important feature of the tandoor is that he consumes a moderate amount of firewood, you can fel well the stove with one arm of firewood.

In addition, I recommend watching a few videos about the construction of the tandoor furnace.

And of course a video about how to cook cakes in a tandoor oven.

Review of the machine for cutting bricks

Bricks processing machines are complex structures that can harm the health of the operator if the treatment is incorrect. Therefore, work on the processing of building materials should be carried out taking into account all safety rules. The device is equipped with a power unit, which works from a network with an operating voltage of 380 volts, so it needs correct grounding. Only those circles that are allowed by the manufacturer can be used as cutting elements. Also, the employee must use protective glasses, gloves and respirator.

A device that is produced at the factory is quite expensive, so if the question arose of how to cut a brick at home, it is better to apply other installations. However, some home masters are trying to assemble such a machine on their own. The parameters of the future device are determined by the capabilities of the designer and the upcoming volume of work.

Some people even decide to completely repeat the design of factory.made machine tools. Other home masters use improvised tools to simulate machine tools. In most cases, we are talking about an angular grinding machine that is installed on the bed.

In some cases, a circle from a simple circular saw is used as a cutting element. This is due to the fact that such a tool can be purchased at almost any household at an affordable price. In any case, it is necessary to remember the safety rules and take all measures to comply with them.

The principle of operation of the machine for cutting bricks

From all of the above, it follows that the modern market offers a huge number of different devices for processing bricks. The choice of equipment falls on the shoulders of the master, and it must be done taking into account the following factors:

How to cut, chop brick

Brick cutting can be carried out using a manual or electric tool.

Not so long ago, professional builders for processing this material and giving individual units of irregular shape used combined cell.

This method is available to everyone, but not without flaws.

So, for example, the disadvantages of this method of brick.ups include low accuracy, uneven, rough faces.

In addition, it is possible to chop building materials only at a right angle.

Hand tools

One of the most popular tools that are used for cutting bricks at home is the chisel.

It is advisable to use the chisel if you need to cut one or a small number of bricks.

To work with large volumes, it is better to use productive power tools.

Cutting the chisel is performed in a strict sequence.

There should be no cracks, chips, downed corners and other visible defects on their surface.

Using a chalk or trigger trigger, apply a marking on a brick, according to which we will carry out an incision.

The working part of the chisel (sharp end) put exactly on the drawn fishing line for the trimmer.

We take a hammer and begin to carefully tap on the chisel until the brick breaks.

As a result, we got two parts with rough surfaces.

To make them smooth, you should rub the elements about each other.

Kirpiche Kirpich is carried out using a special chisel for masonry.

They are stronger and more reliable than ordinary models.

Such products are made of high.quality alloy (chromomolibden or chromovanadium steel), resistant to increased mechanical loads, wear, have a long service life.

Choosing a chisel with which you will cut a brick, do not save.

A good tool will last for many years, maintaining functionality, and low-quality will come into unsuitability after 5-6 use.

Corner grinder is a universal instrument that is definitely in the garage or utility of each household man.

If we are talking about cutting bricks, then the scope of this apparatus includes low.rise construction, small.scale production.

Simply put, if the acquisition of a special machine does not justify itself, it is advisable to use an angular grinder for cutting bricks.

To cut the material using this power tool, prepare:

Diamond and abrasive discs are used to work with bricks.

They differ between themselves, the scope of use, cost.

The abrasive disk costs cheap, grows very quickly, you can only cut it deeply as a whole.

Diamonds provide high efficiency and safety, have a longer service life.

They can be used to perform holes and openings in a ready.made brick wall.

A specialized brick cutting machine is a productive, high.tech equipment.

a case made of a durable metal alloy;
powerful engine with a drive;
a complex of diamond discs of different sizes (width, diameter, spraying);
brick consolidation system;
water supply system, due to which cutting is carried out without dust.

The advantages of such equipment are obvious.

Firstly, the work is performed quickly and efficiently, you can work with large volumes of building materials.

Secondly, the seam turns out to be even, accurate, the cut brick is perfectly incorporated with other elements, you can put it cut out outside.

Thirdly, the equipment safety system provides the employee with maximum protection.

Brick cutting machines have a long service life, a large working resource.

In combination with the unit, instructions for use are necessarily delivered.

Working with the device is quite easy and convenient.

markings on the workpieces;
fixing brick;
bringing the cutting head to the drawn line;
launch of the unit;
setting the necessary speed;
Execution of the cut.

You can cut chamotnese or silicate brick not only at right angles, but also at acute, receiving triangles, trapezoids and other figures at the end.

When working with the machine, it is necessary to strictly observe safety precautions, so as not to accidentally cause injury.

Technologically complex device is equipped with a powerful electric motor, it must necessarily have a grounding.

The instructions have information about which machines are compatible with one or another model.

So, use only those that are recommended by the producer.

A powerful, productive tool operating on a gasoline engine.

With this unit, you can cut not only brick, but even concrete blocks, natural stone, granite and other durable materials.

Benzores cuts the products individually, and also can easily cope with whole brick walls, easily makes openings and holes in them.

In shape and appearance, the power tool resembles an angular grinder, only its dimensions are greater.

As a cutter, chains and discs with diamond spraying are used.

Features and problems of work

In the construction of the garage, fence, furnace, you have to manually cut small parts of the brick product. To prevent an increase in the consumption of the material, it is cut off with a special tool with obtaining even pieces for further use. Since brick is fragile, the use of a jack of a hammer or a pea is undesirable. So the accuracy and correctness of the form will be violated. To get an even example, brick cutting is performed by special tools and auxiliary, such as a corner (ruler), a pencil. For his own protection, the builder will need protective glasses and gloves.

The first tool was called “Kirka”. They are completely different sizes and are used in different ways. The reverse side of the hammer, which was mentioned in the previous paragraph, performs precisely these functions, however, such a chancery instrument will separately bring an order of magnitude more benefit than attached to another.

You need to use it carefully, light, but accurate blows in the required area. The force that will need to be attached should not smash the brick to shreds, remember this.

The second gadget that I would recommend is special chisels for cutting bricks. Their size and shape allows you to complete the task up to millimeters up to millimeters.

The disadvantage of such techniques is that you will have to make a corner chip with great difficulty, and if this even comes out, then its evenness will clearly be limp to limp. Therefore, the normal joint will not work, and all aesthetics will disappear where it is not clear where.

There was one familiar grandfather in my century, who was considered the best of the best. Like, he himself laid out a stove in two floors in three days. And exactly everything was, and high.quality. I once had to work with him, well, of course, when it came to the end of the side, I had to break off a piece. For this, the grandfather had a special small, homemade chirus.

We recommend reading:

I suggested using a cutting device, for which I heard offensive expressions. In the end, at the end of the work, the customer was dumbfounded, how much the material was spoiled. I told all this to the fact that be prepared for a huge number of waste materials, unless, of course, you understand that the use of more new methods is more effective.

Tool cutting

It will go much faster, more precisely and better, if you use a tool for cutting brick. His choice is not too extensive: usually used an angle grinding machine (corner grinder), benzores or a special brick cutting machine for this.

Without a construction square and pencil for applying marking, one cannot do in these cases. In addition, you will need personal protective equipment, since the cutting process is accompanied by the formation of a large amount of dust and small fragments. These are gloves, glasses and a respiratory mask.

Corner grinder

Than to cut the brick if you need a small amount of non.standard stones?

For this purpose, an angular grinding machine is best suited, which is popularly called a corner grinder. Unlike equipment, which will be discussed below, almost every home master has such an tool.

Advice. It is recommended to use a corner grinder with a capacity of about 2 kW. A less powerful tool may not cope with the task, but it’s hard to work too powerful.

A disk for cutting brick installed on the machine can be of two types:

Abrasive. inexpensive, but not too practical. It is quickly “erased” and can deform or crack during the saw process, which will affect the quality of the cut and safety of the master.

In any case, the optimal disk diameter is 23 cm. A smaller circle will not break the brick over the entire thickness, so it will have to turn it over in the process. But too big circles are not so convenient to work.

Diamond discs, in turn, differ in the type of edges and are: there are:

With a solid edge. The cheapest of analogues give an even surface on the cut. But heat up during work and wear out faster.
With a gear turbocharged edge. The cloves on it are located in a spiral, so the dust and other waste is well diverted from the working area. Such discs can be used for dry and humid cutting, they have the longest service life and the best working characteristics.
With a segment edge. In such disks, cuts are made along the edge, dividing the working plane into separate sections. The section of the cut during operation with such a disk is constantly ventilated, so it heats up slower. But with wet cutting, there is a risk of waste flipping in slots, so it is used mainly for dry cutting.

How to cut bricks, and which disk is up to you to decide. Now you know about the features of any cutting nozzle.

You just need to remember that it is necessary to cut not exactly along the marking line, but a little retreating from it so that the marking remains “in the body” of the part you need. Otherwise, due to the backlash of the instrument and thickness of the cutting part of the disk, it will turn out less than the required size.

Holding a corner grinder on weight, it is difficult to make a quality cut. It is better to fix it and brick in a clamping bed. With its help, you can make a neat cut not only along or across the brick, but also from any angle.

A special bed for corner grinding faces will facilitate the work

It is very important when performing such work do not forget about safety precautions.

The instruction requires the following points:

How to cut a brick in half lengthways | cut brick slips

The tool must be held with two hands so that when the reverse it does not break out of his hands and does not injure you or to others. This requirement will also ensure a higher cut accuracy.

During work, a stable position and the correct capture of the tool are very important

An electric supply cable should be at the maximum possible distance from the working area in order to avoid cutting it or wrapping a disk with all the ensuing negative consequences.
It is possible to release an angular grinder from the hands and put on the ground or other surface only after the disk rotation is completely stopped.
The cutting circle must be closed with a protective casing. You can’t use a corner grinder without a casing

Brick cutting machine

Special brick cutting machines are expensive, it does not make sense to buy them for one.time work. This complex equipment is intended for those whose activities are related to masonry work.

It consists of the following nodes and elements:

Metal bed;
Power unit with an electric motor and a diamond circle;
Brick or stone fixation system;
Most models are also equipped with a water supply system to the sawing zone.

Such equipment allows you to quickly and with high accuracy will perform a cut of any complexity. At the same time, the master is always visible to the process of cutting, he can control it.

And the irrigation system minimizes the amount of brick dust thrown into the air, doing the work as comfortable and safe as possible.

How to cut a brick using this machine?

You need to mark it and install it in the working area, fixing in the right position;
The cutting part of the tool is lowered to the working area and focused on marking;
Then turn on the engine and set up the speed of rotation, after which the cutting is carried out. In the photo. the process of cutting brick on the machine

Sometimes there is a need for cutting not individual bricks, but in cutting in brick laying of various niches, door and window openings. In such cases, the most effective tool will be a gas tank with which diamond cutting of brick walls is carried out.

Possessing great weight and considerable dimensions, it is not convenient for piece work, but indispensable for sawing masonry and dismantling work.

Benzorezer is, in fact, a circular saw with a gasoline engine, a cutting tool in which there can be a disk or a chain with diamond spraying. The saw with the disk looks like a large corner grinder, and with a chain. a chainsaw.

Shamotnaya brick: scope and choice of choice

When erecting structures, the operation of which is associated with high temperature modes, special refractory materials are used. In the segment of fire.resistant materials, not the last place is occupied by a brick from Chamot. What is chamotis brick and what its features will tell in the material below.

Features and scope

Chamotum brick what is it? A visually shame is a product of saturated straw-yellow color, its characteristic feature is a dense porous structure.

Shamotnaya brick. building material for 70% consisting of refractory or so.called chamotis clay. In addition to clay, the block includes special additives, in most cases, an additional component is aluminum oxide. Aluminum oxide has a considerable effect on the technical characteristics of bricks, its strength and resistance to negative chemical influences.

The fireproof properties of chamotte are affected not only by the composition of chamotis bricks, but also by the technology of its production. The technological map includes such stages as a molding of raw material and its further firing at very high temperatures. In the production process, all stages and temperature indicators are controlled by specialists.

The fireproof block of chamotte clay has found its application both in the industrial sphere and in everyday life. This fireproof material is used in the construction of furnaces, fireplaces, a furnace furnace lining, and smoke channels laying.

Types of fireclay refractory brick

Classification of building refractory material is carried out according to several characteristics, in particular:

According to the method of forming raw material material, the following types of chamotis brick are distinguished:

cast from a slalker or melt;
molded half.dry method;
melted;
hot.propressed;
Thermoplastic.pressed.

Depending on the shape of the finished product, there is:

The most popular is the shame of a rectangular shape, when erecting arched structures, brick brick is indispensable.

A particularly dense block. granularity does not exceed 3%;
High.minded shag. the degree of porosity varies in the range from 3 to 10%;
dense-granularity is 10-16%;
Sealing refractory-porosity 16-20%;
medium.density. the degree of granularity from 20 to 30%;
Shadow with increased porosity-an indicator of porosity is in the range of 30-45%;
Gunny brick lightweight. granularity from 45 to 85%;
ultra.lighting. over 85%.

Specifications

Quality indicators of fireclay refractory building materials controls the state standard. GOST installed:

the composition of the raw material material for the production of chamotte indicating the percentage of impurities;
thermal conductivity of chamotis brick;
porosity;
the dimensions of chamotis brick;
geometric parameters and other technical characteristics.

Today in the building materials market you can find chamotis refractory blocks made in accordance with the manufacturer. Indicators of such products may differ from the norms that the state standard establishes. When choosing a building material, it is better to give preference to the GOST product, the GOST mark is a guarantee of the quality of building material.

The main technical characteristics and their chamotte indicators established by the standard:

fire resistance-1100-18000s;
Density-1700-1900 kg/m3;
thermal conductivity. 0.6 W/m0s;
porosity-3-85%;
Frost resistance class. from 15 to 50;
strength class. from 75 to 250.

Advantages and disadvantages of building materials

Based on the technical characteristics, chamotis blocks have the following advantages:

high fire resistance;
high strength;
resistance to atmospheric negative factors;
resistance to deformation phenomena;
long service life;
Good heat capacity.

Chamotis size and weight

The weight of the charged brick presented on the building materials market varies in the range of 2.8-6 kilograms, GOST Standard sets the permissible mass of the product up to 3.7 kilograms. I would like to note that the thermal conductivity of the material depends on how much the shame weighs. The heavier the material, the longer it retains heat.

The size of the chamotum block depends on the brand and shape of the product. Despite the variety of geometric shapes, the most popular chamotis material in household construction is a rectangular chamotis brick. The size of the product, as a rule, complies with unified standards. The most common sizes:

Marking of chamotis brick

Marking on chamotis refractory bricks is applied on one of the faces of the product.

Marking consists of letter and digital designations (from 5 to 47). The letters indicate the physicochemical properties of building materials. The following letter designations are used to mark chamotte:

Sha, SHB, Shak. General purpose chamotte blocks, characterized by strength and ability to withstand temperatures up to1690 0C. These brands of refractory bricks are in demand among private developers, thanks to the optimal ratio of quality and cost of building material;
SHV, noise. shared industrial purpose, differ in high heat capacity, is used to erect gas generators, cladding of the enclosing structures of convective mines;
ShK. brick is used in the construction of industrial equipment for the production of coke;
SHL. chamotum fireproof lightweight brick with a high degree of porosity, is widely used for functions of furnaces, withstands the exposure to temperature up to 1300 0C;
SHCA. bilateral end fireproof blocks from chamotis, found use in the construction of rotating elements of furnaces;
PB. everyday shamot of domestic purposes;
PV. refractory products used for the construction of chimneys, the inside of the fireplaces.

Fireproof brick. Properties, characteristics, application and price of refractory brick

The fireproof brick is not intended for “resistance to fires”, as many people far from construction believe that it is produced for building fireplaces, furnaces, stationary “summer” kitchens and everything else that brings fire that brings harmony and peacefulness to people, or contributing to the preparation of a delicious barbecue.

Description and characteristics

The fireproof brick for the furnace, although it is made, like simple, from clay, but in the clay mixture at the stage of production, that is, before pouring it into forms, a number of substances are added, which make the final product resistant to the influence of fire and the same impurities determine the belonging of ready.made bricks to one or another type.

Any varieties of such bricks are inherent in the following characterizing features:

low thermal conductivity, which makes the material optimal for the device of street “kitchens” in places of rest or open fireplaces;
resistance to the action of high temperatures significantly increases the life of the fireplace or any other structure, compared with the possible duration of the same structure from a simple non-fire red brick;
increased, again, in comparison with ordinary varieties, inertial thermal properties, that is, this type of bricks heats up much longer than ordinary, but just as long and cools, all this time giving heat to the room, if we are talking about the furnace;
The properties also include a higher ability to confront the hot gland, burning of gas and so on, that is, a “for a wild boar” turned “for a wild boar”, mounted in fireproof bricks will not destroy the material, and if he turned to a fireplace of simple bricks, then the cracks will appear quite The same quickly, the same applies to the firefights of the lattices, to the baking sheets in the furnaces and another, as for the gas, to bring the gas pipe into the fireplace, the stationary “barbecue” or the stove and provide the permanent and regulated “bonfire” is completely easy, although quite unusual;
The low probability of shrinkage or growth, that is, changes in “volumetric” indicators during use of the object, this, in principle, is characteristic of all types of brick, but in refractory this characteristic is the best.

In general, for targeted use, that is, for the arrangement of the stationary buildings in which bonfires will be “divorced”, this type of brick is ideal, but there is no sense in building a house from it, of course.

Trade brands of refractory bricks that can be purchased either right from the manufacturer or in stores:

Magnesite basic-this type is “cooked” with the addition of magnesites and limestone, has the highest characteristics, it is modern steel furnaces that are built from it, any other structures for steel, blacksmithing, chemical and other similar production;
Carbon mixed. brick, in which carbon compounds are added in appearance very similar to paving slabs or to activated coal tablets, is very suitable for arranging domain furnaces and if you build a fireplace or street “kitchen” from it, you can get not only a high.strength building, but And the appearance is extremely unusual and attracting attention, because black furnaces with castings with castings in swamp, greenish or other shade are quite small;

Quartz mixed. this variety is made with the addition of a mixture of quartz and sandstone, of course, has all the characteristics of refractory, but has a certain feature. not tolerance of alkalis, simple contact with alkaline substance is able to completely destroy the construction of this brick, then it is significantly damaged;

clay. the most common type of bricks in the “domestic” application, calmly withstands temperatures from 1000 to 1500 degrees (maximum 1695), it is inexpensive and easily tolerates the difference between temperatures, that is, to make fire in a street stationary barbecue built from the “clay market “On the January holidays, it is quite possible, the stove does not crack from the difference in temperature inside and outside, it is from it that various finished furnaces, barbecue, small fireplaces and other similar products sold for transportation and installations are built, and not under construction on the spot.

In addition to such a separation caused by the impurities used in the “cooking” bricks, there is also a distribution of categories related to chemical properties:

“Acidic” category-it includes bricks that can interact with an acidic environment without any damage;
The “alkaline” category. it is represented by bricks, calmly related to the effects of alkalis or contact with them;
The general “neutral” category-this includes a brick fireproof “SB”, a brick fireproof “Sha” and other types, equally indifferent to the action of alkalis, and to the influence of an aggressive acidic environment, that is, to the appearance of any oxide and so on.

The unconditional advantages for the targeted, of course, use, which the brick is a shamot.based fireproof brick, should be attributed:

less, in comparison with simple brick, weight;
high indicators of thermal intensity and heat capacity, that is, heating and thermal return;
produced bricks can be of different sizes and shapes, and not just standard;
A very aesthetic and diverse appearance, that is, you can significantly save on the decoration, and there are a lot of options for design, if you wish, you can arrange alternating colors-white, terracotta, black, or something else, there are practically no restrictions.

As for the presence of minuses that any absolutely material has, the most significant are:

It is almost impossible to cut or break the brick, the structure should be “adjusted” to the size of refractory bricks, and not vice versa;
The cost is higher than that of a simple “red” or silicate;
When acquiring, it must be borne in mind that a completely budget type of bricks, “boiled” with quartz, does not make alkaline effects.
