How to saw an electric saw gas block evenly. Electric saws – recommended by amateurs and professionals

Features of machines for cutting gas block

Aerated concrete, being modern and technological material with its own set of physicochemical properties, requires high accuracy in laying and cutting. For this, a whole class of tools has been developed, which will be discussed in this publication. It will be told about what to saw aerated concrete blocks, and how to do it correctly.

You can saw aerated concrete blocks with both manual and mechanized tools, each of which has its own advantages and disadvantages.

Hand saw

The small density of the material allows you to cut aerated concrete blocks with hand saws with a special shape of the cutting edge. It makes sense to apply such a tool if the volume of work performed and the form of the constructed design is simple, without intricate geometric transitions.

• The advantage of a hand saw in its low cost. The cut can be performed, even while on the goats, at a height, where other equipment will not work. That is, we are talking about mobility, thanks to which a hacksaw on aerated concrete always has a reserve for masters, and is used as an additional tool.
• Of the shortcomings, the low accuracy of the cut is noted. It is corrected when cutting along the guide frame setting straight to the block.
• Manual cut requires the master a lot of effort and time. A separate person is always engaged in this work in brigades. This indicates the impossibility of using such a tool as the main thing in the construction of large.scale objects.

The correct selection of a hand saw requires the accounting of such factors as:

Despite the apparent softness, aerated concrete blocks quickly dull saws. To make the tool last longer, tools with a winning attack on the tooth are taken. This will not increase the speed of the cut of the material at first, but it will save the saw for a long time.

Saber saw

The electric tool for cutting a gas block repeatedly accelerates the workflow, increasing labor productivity.

If there is a large amount of work, it is worth acquiring a professional tool. It distinguishes it from inexpensive home inventory maximum working resource and the possibility of uninterrupted use during the shift. It is also important to use high.quality files that tolerate overheating better, preserving the properties of the cutting edge at the right level. Sable saw externally and on the principle of action resembles an electric jigsaw. Only thanks to the configuration of the case is it a more convenient and universal tool for sawing aerated concrete blocks.

• This tool is made by direct and curly cutting of aerated concrete. the performance of complex turns requires the operator of experience and skill.
• The cutting of aerated concrete blocks is carried out by flat metal canvases, which, due to the pendulum course of the internal parts, are given progressive movements.
• Like any other tool of a similar type, the saber saw has an electronic control unit. It allows you to control the speed of rotation of the electric motor, by changing the resistance to the electric current.
• It is also possible to adjust the depth of the pendulum passage, which varies from 2 to 5 cm. This parameter should be checked when buying a tool, as it may differ from the model to the model.
• The frequency of every minute movements can reach up to 3,000 cycles, due to which aerated concrete blocks are cut very quickly, without a large cost of physical strength.
• Inside the tool is installed on the shaft of the impeller, creating a directed air movement, which effectively removes heat from the motor and cutting edge. Recommended operating modes and permissible heating should be sought in the instructions from the manufacturer. Measures to prevent overheating will also be found there.

When selecting a saw, you should pay special attention to the power of an electric motor. it will be approximately 1000 watts for a good tool. The maximum supported length of the canvas is also important. The larger it is, the larger blocks can be sawed by aerated concrete blocks without loss of cut quality.

If you combine all the important advantages of this tool on one list, then it will appear in the following form:

• High accuracy of the saw.
• High performance and efficiency.
• The possibility of applying a certain depth for a closed cut.
• Cutting grooves for wires and reinforcement.
• For inexpensive Chinese equipment and 10,000-15000 for reliable models from Japanese and German manufacturers. Professional saws from masters such as British Hilti will cost 25,000 or higher.
• High.quality cutting canvases when buying will cost about 1,500, and they will have to be bought separately, since they are not provided for in the kit. Finding them is difficult in view of non.proliferation, so it’s better not to go to the store, but to look immediately on sites.

Attention! On the forums on the Internet, they often write about how saber canvases cannot effectively remove cut products, from which work slows down and jamming may occur. So that this does not happen, the master should additionally make pendulum movements with his hands, as when working with a hand saw. This will give sawdust a way out. Increasing capabilities and mobility allows the use of a battery tool. It is very convenient when working at heights, in hard.to.reach places and when cutting a stroke in the walls.

Saw “Alligator”

Previously, a saber.type saw was considered, a variety of which many consider the saw “Alligator”. However, in fact, this is only partly like this, and this tool has its own characteristics, which the masters should know about.

Additional devices for cutting aerated concrete

All the above tools are universal. For individual specific work, additional devices are used:

• Aerated concrete rubbish. is a grater with a metal sole and a comfortable handle. Designed for accurate fitting the size of blocks and aligning the cutting places after sawing.
• Manual stroobores. a specially bent metal pipe with a handle in a special way, allows you to quickly scratch on the surface of the material of a rounded.shaped depression, into which the valves of the reinforcement and communications are laid (after the construction of the house).
• Electric stroobores. Outwardly resembles a circular saw, but has two rotating parallel cutting disks. Due to the built.in mechanism for adjusting the depth of the cut, it is able to give out perfect slots under the strobes of the desired depth. As an inexpensive replacement, you can use a classic corner grinder with an appropriate disk.
• Crings. you can take standard concrete, with a winning attack. They are used to create deaf and through round holes in the walls for ventilation, boxes of sockets and so on.
• DIY Corner for the cut of aerated concrete. is used to control the course of the cut.

From all of the above diversity it can be seen that a good master should have a tool for each working case.

Where it is used

A distinctive feature of the cutting tool through foam concrete is the presence of carbide winning attacks on teeth. These attacks allow you to solve several problems at once: the type of device under consideration is used to implement the following tasks:

• In order to divide the block into two halves or cut off the excess part
• To finalize the shape of the foam block
• To create a prefix block, which is necessary when carrying out work on laying building materials

Structurally, the equipment consists of two main parts:

A saw for sawing aerated concrete is similar to a hacksaw on wood, but with a slight difference between the shape of the teeth.

A machine for cutting aerated concrete blocks

The highest accuracy and the most even surface when cutting cellular blocks provides a machine for cutting aerated concrete.

It is used to cut massive volumes of aerated concrete with various parameters, which at the output give several blocks with the specified sizes.

It can be installed even in a small area in the garage or in the garden under a canopy.

The machine is an extensive frame equipped:

• Schnek for removing pink salmon,
• Two electric drives,
• cutting elements. tape saws or strings,
• The trigger mechanism of the screw,
• The starting mechanism of the frame,
• winches for vertical movement of the frame,
• Removable rail trolley.

The array of aerated concrete block passes through the screw to obtain even sides. Then, a frame with cutting planes is lowered on a fixed aerated concrete, which cut the monolith immediately along and across the individual blocks. Finished products are transported to a warehouse.

This is an ideal device to cut blocks.

It should be said that each master makes the tool on his own.

However, construction professionals never use the equipment for other purposes, because to restore the tool, for example, to achieve the necessary quality of sharpening, and besides, it is almost impossible at the right angle. The high cost of a good tool is justified, because it is made of superhand alloys and materials with high constructive properties. Do not save on a quality tool!

Ribbon saws quickly and efficiently cut gas.sized blocks. This machine has high performance, it allows you to cut aerated concrete about 20 times faster than using a hand saw. The guide canvas is made using special technologies from a solid metal alloy, the height of the working surface can be adjusted. The cost of such a car is about 5000-6000 euros. Let us consider in more detail the Lissmac production saw designed for cutting gas silicate blocks. Aerated concrete blocks when using this machine can be sawed not only in a straight line, but also diagonally.

The main advantages of this machine are:

• Automatic tension of the cutting disk, which allows you to cut with high accuracy aerated concrete blocks;
• Direct drive of the drum through gearbox. Excludes any maintenance of the drive elements;
• Superflow guide rollers of the cutting blade: to ensure its long service life;
• A large gap of cutting blades in the car, which ensures the rapid removal of waste and guarantees a continuous workflow;
• The fabric tape is replaced by a rapidly removable connection on the desktop;
• For the convenience of transportation, the car has a lifting eye and transport wheels;
• For more reliable stability, the model is equipped with stops.

Strogerez for aerated concrete

When laying grooves for reinforcing rods, pipelines, wiring, Internet cables, television and other communications in aerated concrete, wall cutters are used. They are divided into manual and electric.

There are two types of manual grinders that process aerated concrete. The first has a curved handle with holders for two hands. Double.sided knife is attached by bolts.

This tool for cutting aerated concrete is very convenient. Two holders provide uniform pressure, which significantly accelerates the workflow. Another type of shredder also has two holders, but it is direct. Using this tool, it is easy to make grooves and spacers in gas silicate blocks. Its use allows you to perform work with high accuracy.

Electric trobores for processing aerated concrete is made in the form of a small device with two rubber rollers, which greatly facilitates the movement of surface cutting tools from gas.musheated blocks. The rotating case has several incisors with a drive of the tool electric motor. Hand holders are located above the rollers. Electric cutters are produced by many companies, the most popular of them: Makita, Sparky, Prorab, Bosch, Elmos.

A manual tool is considered a universal tool for sawing gas.free blocks. Can be used under any conditions, including in the absence of a power grid. The use of electric saws is much more functional, but at the same time expensive and unsuitable without a power source.

Manual hacksaw

Choosing how to cut an aerated concrete block for the manufacture of a good thing, first of all think about the simplest tools. The hacksaw is quite able to cope with such a task. according to the sensations, manually cut the aerated concrete block approximately similar to cutting a wooden sleeper. However, the usual manual hacksaw is not suitable here. First, she is too short. The size of the blocks, as a rule, is 60 × 25 × 20 cm (D × W × B). The standard carpentry hacksaw cannot completely block such a briquette, it moves to the side and the cut turns out to be uneven, inaccurate. There is another problem. the metal tool metal is designed to work with wood, and teeth, as a rule, are not equipped with carbide attacks. They quickly dull, after which the hacksaw cannot be used, she will have a long and laborious sharpening.

A special hacksaw is used to work with aerated concrete, with an elongated base and carbide attacks on the teeth. She is deprived of all the shortcomings of an ordinary tool, although the principles and techniques of working with it remain standard. Cutting the material with its help is a fairly laborious lesson, but, in the absence of connection to the mains, this is the only and indispensable option.

CARNOLLA, how to make yourself

The size of the gas blocks is quite large (and in some gas blocks it is simply large). Cut off such briquettes evenly and without deviations from the vertical (or perpendicular) simply by eye, without additional devices, is extremely difficult. However, there is a special knock (more precisely, a square), with which you can provide sufficient accuracy of cutting. This is a device made of metal corners (as an option. corners and tubes), located exactly at 90 ° relative to each other in all three dimensions. If you attach a knock on the gas block, you can accurately note a fishing line for a cutting trimmer. You can cut both along the intended line and directly along the square, using it as a guide device. For greater accuracy, the block is rotated several times to ensure the maximum accuracy of cutting.

The device is inexpensive, but, to buy it, you need to at least spend time on a trip to the store. If we take into account that you will have to look for a knock and spend money, it is easier to make it yourself. This is not a difficult task if at hand there is an angular grinder with a cutting circle, a welding inverter with a set of electrodes and several pieces of a metal corner. It remains to cut off the three main parts, grab them to each other and accurately align them at an angle of 90 °, using the square. After that, they check their position and weld completely, set the handle to hold the square during operation, clean the seams. If desired, the device can be painted, although this will not affect the quality of work.

Tools for cutting aerated concrete in length and width

It is easy to work with aerated concrete. You can cut a gas block with manual or electric saws, which allows them to make various structural elements of buildings and buildings of any geometry.

Band-saw

A ribbon type for cutting gas blocks. professional high.performance equipment. Allows you to saw aerated concrete blocks to narrow parts. They are not used for the construction of individual houses, and in the construction of large retail or industrial facilities they are often used.

The machine is divided into the upper and lower part, between which the working area is located, where the blocks are sawn.

The working blocks provide wheels on the shafts, driven by the electric motor. Between them, the working sheet is pulled almost in the same way as a chain.

One part of the canvas is placed in the machine, so it is not visible, and the second passes through the working area. an iron plate with markings.

There are two buttons on the machine to turn it on and off.

An effective dust removal system is provided, which allows you to create the necessary conditions for long and continuous operation.

• It has maximum performance. The material is cut very quickly.
• Has an extremely simple design, so it can be served by yourself.
• Allows you to put the electric motors of the desired power.
• Can easily cut thick blocks.
• The movement of the working unit allows you to make even round cutouts.
• Thanks to the guide system, the exact cuts of the cut are obtained.
• Does not allow you to cut holes.
• For work, you need a professional who knows safety precautions, as the cutting tape can cause fatal injury.

Due to large dimensions, a capacious truck is needed to transport the strip machine.

How to saw with a hacksaw

Due to the low density, you can cut an aerated concrete block with hand saws with a special cutting edge. It is advisable to use this tool if the volume of work is small and the configuration of the elements of the elements is simple.

It is profitable to use this saw because of its low price. You can work at a height, where it is extremely difficult and often impossible to rise with other equipment. This allows the master to quickly perform the necessary operations, since the hacksaw is light and always at hand.

Of the disadvantages, it is worth highlighting the low accuracy of the cut. This problem is solved with a cut on the guide frame, which is installed on the block. With its help, the cut will be more even.

Mostly a hand hacksaw is sawn aerated concrete at home.

When choosing it, the following aspects must be taken into account:

Saber saw

Effective for cutting a gas block, so it can significantly save time and time. The tool is inexpensive, so even for the construction of your own home, the purchase will be justified.

Sabel saw cuts the material due to the quick rotational-settings of the shift blade. The length of the cutting blade can be different, but for comfortable work, experts recommend using canvases longer than the thickness of the block.

• Accurate cut.
• Great performance.
• Allows you to make closed cuts.
• You can make grooves for electric wiring and reinforcement.

The chain saw is electric

This tool allows you to saw a gas.sulcate block and cut into it deaf holes or slots of different shapes. It is considered universal because it is able to cut various building materials.

The advantage of the saw is that it saws the material due to the rotation of the cutting edge in one direction. This allows you to effectively remove sawdust from the working area, while the rod does not hit the material in the process of deaf cut, which reduces the risk of jamming of the saw.

Using a power tool, you can cut U-shaped grooves.

• Blocks can be cut directly in the masonry.
• You can work in many positions (saw at an angle, at a height, etc.D.).
• For an even saw, it is equipped with guide tires.
• Aerated concrete circuit going on wood, but is quickly stupid, so you have to buy a chain with a winning spraying at a price of about 2,000
• The saw itself costs from 10,000
• As a result of prolonged work, it heats up greatly, which leads to stretching the circuit. If you do not remove one link from the chain in a timely manner, it may jump off. Because of this, you need to periodically give it to cool.
• Pilage stars quickly wear out. They are not expensive, but a lot of time is spent on replacing them.
• It turns out a very thick cut, so it is required to lay more the solution between the blocks.

Electric chain saw. a traumatic tool, since the cutting mechanism is open. Many workers are injured annually as a result of working with him.

Additional devices for cutting aerated concrete

In order for the cutting of aerated concrete to be accurate, it is better to do it yourself. a wooden rectangular structure in the form of two letters P, fixed on the platform with corners. The block should be placed inside these letters. There should be a normal gap between them to perform the cut. The gap should allow the saw to move freely, but at the same time it should not go to the sides. In the plane of the platform, it should be larger than from the sides. This will allow waste to be pouring there during work.

Safety measures when sawing aerated concrete obliges to use certain technologies taking into account the tool used, as well as overalls (costume, boots or boots, gloves or mittens) and personal protective equipment (respirators, masks or glasses).

Electric jigsaw

Masters know such a jigsaw as a saber’s saw. This saw is used in the construction of medium and large facilities.

On the jigsaw you can change the blades (put wheels with different sizes of teeth, change the blurted or spoiled discs; the shape of the cloves on the disks can also be different. large and small teeth).

As a rule, for the convenience of builders, many models of saws are produced with interchangeable batteries so as not to be attached to the power source.

When working with this type of tool, it must be remembered that cutting wet material is not permissible, this may entail injury. Saw “rinses” crumbs and can injure the builder.

Before starting work, it is better to try on the tool. Lose a saw with a saw without on food.

It is necessary to cut the middle part of the saw, the length of the working cutting surface should be approximately 25 centimeters.

In order not to be injured, you should hold the saw tightly in your hands.

Classification of hacksaws

Careboods are divided into several types: on wood, metal, aerated concrete (foam concrete) and drywall. Such a division is due to the fact that the saws that differ in the teeth, as well as the shape of the tool, are designed for different works. For example, a wood hacksaw can cut not only wood, but also aerated concrete and drywall. And the metal tool cuts metal, but it is capable of cutting and all other materials.

On wood

You need to approach the purchase of a hacksaw on wood carefully. They differ from each other in the shape of saws, handles, varieties of teeth

Classic hacksaw is also called ordinary or wide. This saw cuts wooden things along or across. Triangular teeth of a saw, the step between them is from 1.5 to 6.5 mm. The classic appearance quickly cuts wooden products, the only minus is that the thread itself is rough and there is a lot of chips, but for garden work is perfect.

Narrow (outfound). this is a specialized saw. The hacksaw can have teeth on both sides, which provides a more accurate cut. Such a tool is designed for thread when you need to carefully cut out wood parts.

The spike is designed for a neat cut when the cut is beautiful and there are not so many chips. The teeth of the hacksaw have the shape of an isosceles triangle. The saw is used only for transverse threads, the width of the tool is usually no more than 1-1.5 mm.

Types of woodcuts for wood are also divided depending on the shape of the teeth:

However, for the cut of the laminate, such a tool will not work. After 20 cuts it will be very difficult to work, as the teeth will already dull.

For metal

This is a type of saw, which is designed to cut metal structures. Such a tool can cut wood, aerated concrete, drywall, but is not able to cut stone and concrete.

It is better to use a hacksaw for metal, of course, for its intended purpose and cut only metal structures. The saw includes the following elements: a canvas for a hacksaw, fastening frame and a handle to hold a saw.

The tool canvas is unilateral or bilateral. The convenience of the bilateral canvas is manifested in the fact that the canvas of the saw on the metal wear out quickly, it is necessary to update it constant, and when there are two sides, this can be done less often.

When inserting the canvas into the frame for fastening, it is important to do this correctly, otherwise the speed of the saw will decrease, and thus you can break the saw. You can also adjust the angle of inclination for professional saws for metal and make it at 45, 90 or 180 degrees

You can also adjust the angle of inclination for professional saws for metal and make it at 45, 90 or 180 degrees.

By aerated concrete and foam concrete

To cut aerated concrete or foam concrete, you will need to buy specialized tools. Such saws have a certain design with winning attacks. The instrument teeth carry out more rigid cut into the surface of the material.

Khosuovka on aerated concrete is used for both longitudinal and transverse saw. Khosuvka in foam concrete are represented by three types of incisors:

• 2-2.5 mm-used for small parts and neat threads;
• 3-3.5 mm-used for medium sizes;
• 4-6 mm-the product is large, difficult to cut.

By drywall

A hacksaw for drywall or a sprout hacksaw is used to cut this material and also cut out various holes. Such a saw is made of high.quality steel, so it is almost impossible to break it.

The blade of the saw on drywall is thin, the length of the canvas does not exceed 20 cm, the tool has a convenient compact handle, so various parts are cut out with such a saw and do it carefully.

Saw an alligator

The Alligator saw with ignorant people is often perceived as a kind of saber modification, but they have differences.

In the process, “Alligator” sets the canvas of sawing planes.

Their movement occurs in the same way as the movement of the jaws of the crocodile.

Unlike a saber analogue, the cutting canvases do not make a reciprocal movement in this saw, a cut is carried out using a saw tire installed motionless.

• Possessing a powerful engine, the “alligator” is best suited for the cut of aerated concrete blocks.
• The movement of paintings in the in theideic way gives the stability of the block.
• The brake of knives and the switch lock is provided.
• Dust protection and aluminum corps contribute to the durability and reliability of the product.
• Ease of operation.
• Easy replacement of consumables.

The product includes a hexagon and a few paintings in aerated concrete.

The disadvantages of this tool include only the high cost. The purchase of “Alligator” is justified only if professional use as constant equipment for the construction of walls from aerated concrete.

Alligator is the best, but very expensive tool. Its purchase is recommended to professional builders who build more than one house from aerated concrete. For a private developer, it is better to choose less expensive solutions described above.

A machine for cutting aerated concrete blocks

The highest accuracy and the most even surface when cutting cellular blocks provides a machine for cutting aerated concrete.

It is used to cut massive volumes of aerated concrete with various parameters, which at the output give several blocks with the specified sizes.

It can be installed even in a small area in the garage or in the garden under a canopy.

The machine is an extensive frame equipped:

• Schnek for removing pink salmon,
• Two electric drives,
• cutting elements. tape saws or strings,
• The trigger mechanism of the screw,
• The starting mechanism of the frame,
• winches for vertical movement of the frame,
• Removable rail trolley.

The array of aerated concrete block passes through the screw to obtain even sides. Then, a frame with cutting planes is lowered on a fixed aerated concrete, which cut the monolith immediately along and across the individual blocks. Finished products are transported to a warehouse.

This is an ideal device to cut blocks.

It should be said that each master makes the tool on his own.

However, construction professionals never use the equipment for other purposes, because to restore the tool, for example, to achieve the necessary quality of sharpening, and besides, it is almost impossible at the right angle. The high cost of a good tool is justified, because it is made of superhand alloys and materials with high constructive properties. Do not save on a quality tool!

Review of all tools

To work with aerated concrete material are used:

• special manual hacksaw;
• chain saw of electric;
• saber’s saw;
• saw “Alligator”;
• machine cutting machines;
• Devices such as milling, disk, etc. can also be used. P.

Further in the article we will consider the above tools, their pros and cons, as well as draw conclusions about how and with which it is preferable to process aerated concrete.

What to take into account when choosing?

As for the manual tool, the optimal option for processing aerated concrete will be a model with teeth equipped with winning attacks. Its high cost may well be justified by the high strength of the tool. This will not affect the time of the cut (it will be quite long), but the safety of the material and the accuracy of cutting will be higher. It is better to cut large.sized blocks using a two.handed tool, but its weight is much larger. you need a partner.

It is preferable to use the products of a well.known company, and not to purchase a handmade tool with a dubious quality of manufacture. The manufacturer of the Utong tool produced perfectly. A good economy version is the products of the trademark “Delta”. With a hand hacksaw, neat sections are performed, window or doorways are formed. Lack of such a tool. you have to cut at a low speed.

When buying electric saws, it is necessary to pay special attention to its characteristics. The power of domestic models is relatively low, overheating can happen less than half an hour and you will have to periodically disconnect them. They cost about two to three thousand, while the cost of a professional saw can surpass this amount 10 times.

But the instrument of this class is designed for a daily work schedule providing for continuous work. In this mode, the saw can work for more than 5 hours in a row. They are with power from 500 to 1500 watts.

By type of drives, the tool is divided into:

• cord, more powerful and productive, but not so mobile (you will have to use an extension cord);
• battery (electric hacksaw has less weight, it is processed by aerated concrete at construction sites).

In addition, it can be noted that there are functions such as speed adjustment, replacement of the canvas without the use of keys. It is good if the saber saw has anti.vibration protection.

When acquiring consumables for electroplays, it is necessary to pay attention to the type of cutting tooth. The size of the teeth and the interval between them indicate where they should be applied. For example, equipment with a large cutter is used for high.speed cutting, with a small one. with figured cuts. The smallest interval of teeth gives perfect cuts of cut, and with a large wiring, cutting time is reduced, but this is inevitably accompanied by a loss of quality.

How to cut a gas block with your own hands of safety precautions

To obtain an even and beautiful cut, you will need an angular stencil (knock), as the one shown in the picture.

This device directs the saw canvas in two planes at once. It must be installed on the planned place of the cut. Please note that the marking of the block is greatly simplified. If you buy a stencil there is no desire, it can be made from the scraps of a profile pipe. Materials such as wood-brown slab are better not to use, since they quickly become thinner and will be inaccurate.

• After installing the guide, the saw process begins from its angle. The hacksaw enters the gas block easily, so do not crush too much. after all, it is necessary that the cutting products be removed along the way.
• Complete the cut at the horizontal position of the saw so that a chip does not turn out on the corner.
• The cut of the block will fall on the floor, so you need to put your legs in advance so as not to get an injury. For the same reason, it is necessary to work in rough closed shoes.
• All work must be performed in tight clothes with long sleeves and gloves, especially if you use an electric tool.
• The face should be covered with a mask or respirator to avoid inhalation of a large amount of dust. The headdress is not fundamental, but will help to remain clean by the end of the working day.

How to saw aerated concrete blocks?

If complex forms are not supposed to be on the project of the built construction, then the purchase of an expensive power tool will be inappropriate. The most economical solution will be a hacksaw for cutting aerated concrete, used for work in a small volume.

The quality of the cut is affected by the strength of the block, technology, state/density of the material, humidity. In order for the cutting of aerated concrete to be even, you need a pencil and a square, with which you need to mark all four faces. Next, cuts 2-3 cm deep are performed along three faces (two long and one between them). How long the saw canvas will depend on whether you can get it to the end of the cut or not. The tool must be directed softly, without pressure, which prevents the saw leaving to the side. Also, aerated concrete blocks are often drank using the cub.

Electric disk saw

This tool copes with aerated concrete blocks quickly, but a lot of dust is formed during the saw process, protection for the eyes is necessary. At the same time, this tool is cheaper than a saber saw. from 2.5 thousand.

Ax concrete tips

• It is better to lay gas concrete blocks on glue. For these purposes, it is worth using a proprietary cell that will provide you with a seam between blocks of 1.5-2 mm.

We select the kelm depending on the block used (375 or 365 mm wide). When using a wide gear spatula, the glue consumption increases, it turns out a thicker seam, and the masonry process is strongly delayed.

The thickness of the suture of the solution is too large when using a gear spatula

• For cutting a stroke in aerated concrete, it is advisable to use a corner grinder with a diamond disk for dry cutting. Then the strobes are quickly and easily removed with a gateway.

It is better to cut aerated concrete using the “multimaterial” disc

• To accelerate the process of erecting a house as jumpers above door and window openings, as well as for armo-po-coat, it is easier to use ready-made U-blocks. But if you want to save, then such an element can be made independently from a whole block.

Production of a homemade U-block

• The speed of erecting a house directly depends on the quality of the masonry of the first row of aerated concrete. If it is laid perfectly evenly in level, then the masonry of subsequent rows is faster and easier.

To fit the first row, you can use a grinding machine

• Do not put a laying of a row from two corners to meet each other. So it will be difficult to dress the rows and fit the last element in size.
• To make laying the last block in a row, it is necessary to lay the last two gas blocks without glue, cut the last element taking into account the thickness of the seams. Then we put on the glue first a trimmed gas block, and then a whole element.
• We do the dressing of blocks in the ranks. First we put the last gas block perpendicular to a row on another wall. Thus, he becomes the first in the next row. Then we measure the distance and saw off the element to the desired size. Then we perform the masonry using glue.
• Gas block cutting options:

Plane

Clocking aerated concrete blocks try to give them an even surface, but it does not always work out. The rubble can cope with this task, which leverates the surface of aerated concrete and will make it perfectly smooth. The shirt consists of a wooden base with crashed small teeth, which are located at an inclination.

The chain saw is electric

The use of chain electric saws for a gas concrete cut has advantages, but there are more minuses. Yes, it cuts quickly, helps to cut the U-configuration, convenient for cutting at an angle. But in the process of cutting a chain saw, an electric saw is quickly stupid, you need a chain with winning attacks, which costs noticeably more expensive than usual. In addition, the chain heats up in the process, the tool needs a break.

It turns out that in the use of the chain saw, the electric saw is more convenient for the saber, but it becomes unusable faster, replacing the chain will lead to additional costs.

Hand saw

With small volumes of work, a hand hacksaw is used. With its help, they finish the openings of windows and doors, also without it cannot be cope with when laying the initial tiers of walls. In order for the device that cuts the products to fulfill its function benignly, use auxiliary tools:

• A metal corner, with which the correct angle of cut is controlled.
• Ruler, marker or pencil, which are needed to determine the place of sawing.
• Rubanok for gas concrete products, which equals the surface layer of masonry.

Aerated concrete is one of the hard materials, which means the choice of cutting tools should proceed from the quality of the cutting canvas. Drink with a hand hacksaw, which is designed for wood material, aerated concrete slabs incorrectly. It will take a lot of time and effort. The cutting element of the manual hacksaw should consist of carbide components with larger teeth. A hand saw is available with one handle and with two. The cost of the cutting tool is influenced by the distinctive properties of the tool and the manufacturer.

Manual sawing

The widespread, but incorrect idea that the aerated concrete manually is a long and ungrateful, with poor results (uneven cuts, torn edges, tiring and unproductive).

But for an individual developer, it is possible and necessary to cut the blocks manually, since with a rather thick canvas the cut will always be even, and the porosity of the material does not make a large load on hand. It’s all about cutting technique, in the material and brand of foam block.

If you are going to cut a gas block or foam.concrete brick of class B 2.0 and density (brand) D 400 with a hand sawing. But the class B 3.5 brand Block will make you think about the purchase of an electric cutting tool.

A properly selected manual saw allows you to make several thousand cuts, and it can be complex mowing fishing line in the form of a trapezoid or hemisphere. The conclusion suggests itself: in addition to the brand of foam block, it is important to develop the correct process of the process:

• It is impossible to press on the saw much so that the canvas does not take to the sides. Aerated concrete should not be cut like boards or rails. the material is not cut, but crumbles, so the pressure here is not necessary in principle.
• Before sawing aerated concrete blocks, make sure that they are well dried. wet baby will get stuck in the sawdust and complicate the cutting process.
• A smooth cut will turn out if the block is pre.marked on three sides. Shallow cuts of 20-30 mm are made on markings.
• The canvas should go through the cuts so that there are no deviations on the planes. The saw must be kept at an angle of 45 ° and not crushed on the canvas. So that the sawn piece at the end of the sawing does not fall and does not break off the uneven edges, the block should lie on the stand with his whole body.
• The hacksaw should be long so that the canvas completely and with the margin overlaps the brick along the length.
• To facilitate the work, you can make a tuzo from boards or plywood.
