Shtrob cutting in concrete Cable laying. Tools for stroke walls

How to stroke the walls for wiring

One and common methods of installation of electrical wiring are hidden. This is when the wires and cables fit the grooves made in the wall. The process of making grooves is called a troop, and the grooves are “grooves” or “hrab”. How to do the stroke of the walls for wiring, by what rules, which tool to use, and we will talk further.

The laying of wiring in the strob is a closed installation method. The remaining hole is then sealed with a wall, after which finishing materials are applied. That is, then it is difficult to determine exactly where the wiring takes place. From the point of view of aesthetics, this is good, but from a practical point of view it carries obvious inconvenience: when working related to drilling holes in the walls, it is necessary to consider that the wiring is located somewhere there. You can find it using special wiring detectors, but the gasket itself should be predictable. To do this, they have developed a number of rules that must be adhered to in apartments and houses:

    Strobs are made only vertically and horizontally. Included lines are possible only when laying in visits with beveled walls. in attic, residential attics, stairs. In this case, the straps make parallel to the inclined surface.

These are general rules that concern the stroke of walls for wiring.

Tool for stroke and technique of execution

There is a grandfather method. a chisel and a hammer that does not require electricity, but takes a lot of time and effort. With blows along the chisel, his tip is driven into the wall, echoing some of the material. Then the process is repeated repeatedly. The speed of laying the sednes in this way is very low. Its more or less successfully can be used when stroke of plaster. There will be big problems with any other materials.

The work will go with the power tool faster:

    The best option is a breeze. This is a special tool with two saw discs, setting which set the parameters of the strobes. That is, in one pass, you get two parallel lines in the wall. A certain amount of material remains between them, but then it is quite easily knocked out by a peorator with a special nozzle. a spatula. The advantage of working with a stroberase is a flat strobe, lack of dust, since it is possible to connect an industrial vacuum cleaner. Disadvantage. equipment is very expensive, so for one.time work it should not be purchased. Output. rent in a specialized store.

These are all the methods that are used to stroke walls for wiring in concrete or brick walls. If necessary, make grooves in wood or foam concrete there are certain differences.

Norms and restrictions when strokes of walls for wiring

Before proceeding with the tool to the wall, you need to properly prepare for the process. Initially, it is necessary to calculate the wiring plan on a piece of paper. Outline the places of future outlets, switches and lighting points throughout the house. There should not be too many of them. Each element should be defended by a vital necessity. It is also necessary to take into account the materials of the walls and determine the best way of stripping this material.

Regulatory documents on the distribution of wires are collected in SNiP 3.05.06-85. It is best to study them in detail once, so that then do not redo everything again. Here are the main points that should be focused on when performing work:

  • A strobe (deepening) should be carried out strictly horizontally or vertically. The oblique lines should not be present. The only exception when the wiring needs to be diluted on the walls with a slope, for example, the attic. Then the highway can pass in parallel to the tilt of the wall.
  • Between two electric points, you can turn the groove only once. Each turn is a piercing cable that will heat up more in these places. Such conditions can lead to dangerous situations.
  • Shtrobes have a limit on size. The maximum allowable groove width is 30 mm, and the depth is 26 mm. The total length of the route from the distribution box to a specific point should not exceed 3 meters.
  • It is necessary to follow the indentation: from the battery and gas pipes-at least 40 cm, from the door-10 cm, and from the ceiling and floor at least 5 cm, although it is desirable, it is still desirable to adhere to 10 cm.
  • It is forbidden to make a stroke on internal supporting walls. The thickness of the external walls from a shallow groove will not suffer, but on the supporting partitions you need to take permission of the municipal organ. This is especially true for panel houses. The stroke of the walls for wiring on the first floors should be carried out with special accuracy. the lower walls hold not only the roof, but the entire building.
  • It is impossible to touch upon a tilt of a reinforced concrete structure. This may entail a violation of the integrity of the structure and, as a result, the loss of its reliability. If necessary, grooves in reinforced concrete should be shallow, and the reinforcing mesh is not hurt.
  • When making grooves in the ceiling. you need to calculate the shortest way to the lighting point.
  • In the floor slab of the ceiling, it is forbidden to make strokes. If you need to conduct wiring on the floor, then the best solution will be to make it in a concrete screed. It needs to be poured with calculation on the grooves for wires.
  • Brick walls are easier to cure than concrete. This must be taken into account when choosing a tool and the presence of appropriate skills.
  • With a shit, it is necessary to protect the respiratory tract from dust with a mask or respirator.

Important! Shtrust always occurs with increased noise effects. The whole house will hear your work, thanks to the inevitable vibration of the walls. Therefore, such work should be carried out on weekdays from 10 to 17 hours. Then the mutual understanding of the residents will save your nerves and during the neighboring repair.

Methods of stroke

There are four main ways to make grooves. Their main difference is the use of the tool and the application of the use of this technology.

  • A hammer and a chisel. The disadvantage of this method is the inconvenience of work “grandfathers” tools. Even with good dexterity, it comes out for a long time and with crooked highways. A huge plus can be called the cost. it’s cheap definitely.
  • Shock drill (peorator). Minus. strobe with uneven edges. Pluses. process speed and relative cleanliness during operation.
  • Corner grinder. Cons. a large amount of dust, which is difficult to assemble even a construction vacuum cleaner. Plus. even recesses in a short period of time.
  • Strobores. Minus. the high cost of the tool. For one.time use it turns out too expensive. Pluses. fast, not so noisy, even edges of the stroke, without dust.

Choose a tool for stroke walls

Making in.depth grooves is easiest and fastest with the help of special electrical equipment. But even if at your disposal only a minimum set of home tools, do not rush to give up the intention to do your own hands with your own hands.

We will tell in detail how you can post the walls for wiring, consider options from “grandfathers” methods to professional methods.

What is suitable from the arsenal of a home master

The easiest toolkit, which is almost certainly found in the reserves of any home master. chisel (chisel) and hammer. The chisel is installed with a sharp edge to the drawn marking, we hit with a hammer to get deeper into the wall deeper.

even lines are obtained if you use a hacksaw additionally. it is made of tapes along the length of the grooves, which slightly facilitates and accelerates the process.

But in any case, it will be the most time.consuming and long.term option for manufacturing a stroke for wiring.

On large areas, such a tool is unprofitable: the depth and quality of the grooves made by the chisel leave much to be desired, and it will take unjustifiably time and effort for their manufacture

This method is good because it does not require expensive equipment and special skills to work with it. Therefore, ON Do is still successfully used to arrange short grooves on the walls of supple material.

For example, if there is a need to extend the existing route to connect one or more new devices, when transferring a socket, etc.D.

But if the room has concrete or brick walls, it is better to refuse the grooves with a hammer and a chisel, and use more effective methods of stripping.

Making a stroke for a wiring device according to a hidden scheme is easier and fastest as a gateway. It is equipped with two diamond cutters, the gap between which can be chosen in accordance with the task

Most often in the device of electrical wiring of apartments or country houses, peorators and shock drills are used. They will not form such a clear line as a stroboresis, but are quite suitable for this work

To perform different stroke operations, suitable nozzles are selected: drilling and stroberes with tips destroying the material, shoulder blades with exciting grades

In order to arrange the excavation under the installation of sockets, the drill is equipped with a diamond crown. She quickly, clearly and evenly breaks the hole of the required size with even edges. This operation is not available

Simple power tool to help manual work

An ordinary electric drill will help to improve the speed and effectiveness of manual tabletings. But problems may arise with concrete walls. the drill will “burn”, so we consider several important nuances and the principle of work performing work.

Although the drill significantly accelerates the process of strokes of the walls, but you can not count on this equipment on this equipment with this equipment

  • Draw markings on wall surfaces.
  • Pick up a winning drill with a diameter of 8-10 mm for a drill.
  • Make a “point route”-drill along the lines of the hole of the desired depth with an interval of about 0.5-1 cm. At the same time, you need to keep the tool perpendicular to the wall so that the drill does not go on the bend and does not break. If you need a wide groove. make holes in a checkerboard pattern.
  • When working with concrete or brick, you need to turn on the drill at low speeds and periodically stop to cool the drill in cold water (just make sure that the liquid does not penetrate the device).
  • Then, with the help of a hammer and a chisel, it remains to knock out the intervals.

Although the technology is quite primitive, it justifies itself when conducting a bar for small and medium distances. For example, when wiring wires in one room, a tandem of a drill and chis will allow you to significantly save on the services of builders or the purchase of expensive equipment.

But for a thorough redevelopment of wiring in the entire building or a multi-room apartment, it is better to acquire a specialized tool or invite a master-electrics.

Professional equipment for quick installation

Make strokes by spending a minimum of effort, you can use a special stroborer. Two discs with diamond spraying can be planted at once on this tool, so that neat and perfectly even grooves in one pass are obtained on any surface.

At the same time, the circles themselves will be covered with a casing, on which there is a discharge for connecting a vacuum cleaner in order to prevent the spread of dust throughout the apartment.

Stroborese makes even and the same recesses, after which it remains only to knock out the inside of the groove with a shock or a pedorator

In addition, the design of the stroborester allows you to independently change the distance between the circles and set the desired width and the depth of the groove.

In a word, this is a great solution with the only drawback. the price of the equipment is quite high, so it will be cheaper to invite a hired master than to buy a barborer for a one.time repair.

In the device for hidden wiring, an angular grinder is often used. It is suitable for cutting the furrows in all types of walls

If a grinding machine is provided with a home.made device that allows you to accurately observe the distance, the channel selected in the wall will be even, as when using a stroborer

The lack of strokes of the corner grinder is the need to finalize the channel, which requires an elementary chisel and a hammer

After cutting the guides of the corner grinder, the material separated from the array is selected from the future strobe. The process is laborious, and compliance with the depth of the channel in this case is quite problematic

Quickly perform the tablet of walls for wiring will help:

  • Shock drill or penetrator with interchangeable nozzles. Both devices work according to the same principle: at first with a short drill, holes are drilled with an interval of 1-1.5 cm. Then the nozzle changes to the pointed “Doloto” or “Shovel”, is installed at an angle of 45 degrees to the wall, the device switches to the “without drilling” mode and cleans the groove from the remaining material. This method is good with its speed, but not by quality. the groove still turns out to be inaccurate, with torn edges, cracks and chips.
  • Corner grinder (angular grinder)-if you equip the device with a seduced diamond or turbo-almas disk, it will perfectly cope with the implementation of even strobe. True, work with corner grinding is quite dusty and demanding on accuracy. according to the marking, you need to cut 2 parallel lines in 2 passes, withstanding the gap to the width of the future channel. Then, inside the groove, the material is knocked out by a as a peorater with a “shoulder blade” nozzle or other percussion tool.

Features of work with various materials

In the presence of a correctly made scheme and suitable tools, it is easy to carry the walls of the walls even to a newcomer in construction. But this is if the wall is not carrying and covered with a thick layer of supple plaster.

But what if the internal partitions are made of concrete of increased strength, light aerated concrete or even wood? Consider the nuances of working with various materials.

Strobs in concrete and brick

On a brickwork, fastened with a mixture of sand with cement, you can hide horizontal grooves even with a chisel and a hammer if you “get” into the seam. For vertical stroke, it will be better to use the power tool. an angular grinder, a peorator, or a strobore.

If the masonry is closed by plaster, you can cope with primitive manual equipment, however, the process will take a lot of time.

Rules for marking the stroke for wiring on brickwork: horizontal channels are knocked out at the junction of rows, vertical. between rows of bricks

In principle, there is nothing complicated in working with concrete. even though the material is quite durable, the grooves on it can be made by any tool suitable for stroke, except, perhaps, a hammer and chisel.

But the best choice will still be the peorator, although the evenness of its grooves leaves much to be desired (however, all the nuances will correct the plaster).

The level of noise from the peorater exceeds 60 dB, and in order not to injure neighbors, it is allowed to perform work with it only on weekdays and in the daytime, taking periodic breaks for 1-2 hours

This shock tool has high power, so it will cope with any hard surfaces. He does not form such a large dusty cloud as an angular grinder, and does not require an additional tool to prove the remnants of the material inside the furrow.

The peoporator and drill are suitable for the formation of round holes, though the master will need experience: for this:

Before drilling a round hole in the wall with a with a pen or drill, we mark the socket directly to the installation site

According to the marking of Burim points with a step of 1-1.5 cm, better even less. The more often the points are located, the faster and more accurately the hole will be formed

We combine in a continuous circle drilled along the contour of the point. Then, with the same nozzle, we achieve the necessary depth of the recess

After reaching the necessary depth, a hammer and chisel enters into battle with a “. All superfluous must be banally chopped off and remove

In addition, on concrete walls of increased strength, use a corner grinder (and its analogues. a circular saw, an angular grinder) is unsafe. with a strong pressure, the circle may break.

How to work with wood and aerated concrete

You can make grooves in the walls of aerated concrete or foam blocks using corner grinders, drills, peorator or circular saw. But if you want to minimize the amount of dust, use a special manual strooborean designed to work with supple material.

Its pointed arc easily cuts out a neat groove, and the desired depth can be achieved in just 3-4 passes.


By the way, it is easy to make such an instrument with your own hands from a plate imprisoned on one side or a hard peaolent. To do this, you need to bend an arc of a small segment of improvised material and fix the edges with wire or island.

For small volumes, such a device is quite enough, but if you need to conduct a network of channels with a total length of more than 20 m, it is worth equipping the device with a comfortable handle from the pipe.

As for the walls from a profiled timber or a gallected log, then, according to fire safety rules, the installation of open electrical wiring is recommended here so that in the case of force majeure it is possible to quickly neutralize the source of ignition.

In extreme cases, for wooden walls, you can use a special milling cutter, a corner grinder with a circular wood disk and a chisel, with which you can remove the material between the tiles.

But, we repeat, it is better not to risk camouflage wires and perform installation without violating the standards of the PUE and the integrity of the wooden coating.

Nuances with load.bearing walls

As already mentioned, it is forbidden to stroke the supporting structures. if the upper layer is damaged in the wall, the reinforcement is exposed, as a result of which corrosion may begin, which will weaken the entire frame of the building. But what about the owners of apartments in the house where part of the partitions are made of reinforced concrete or most walls carrier?

shtrob, cutting, concrete, cable
  • Official approval. to obtain permission to carry out work on a posting in the local construction department. You can try, if you prove that the depth of the grooves will not affect and does not damage the reinforcing mesh, the deformation of which leads to the begging of the supporting structures. But if we are talking about a panel house-the chances are almost zero, but for a frame-brick building, permission will most likely be given.
  • Apply a plaster layer to the wall and carry out a stroke without delving into the design of the slab itself. Typically, the reinforcement lies under 1.5-2 centimeter layer of concrete, therefore, if you level the wall with a plaster mixture, the depth of the grooves will not affect the metal.

And the last way to help solve the issue with any problem wall is to hide wires behind drywall or in special electrical skirting boards.

Preparatory measures and marking the work surface

To obtain furrows in the walls from non.combustible structures, a set of tools from the list is selected:

  • locksmith or construction chisel and hammer;
  • electric drill or peorator;
  • corner grinding machine with a set of abrasive disks;
  • Special electric stroobores (or furrower).

A special detector is used to detect the lines of old wiring and reinforcement inside the walls.

Since the equipment has a high cost, when repairing on their own, an indicator screwdriver is used to search for cables. The device allows you to find a wiring with a depth of not more than 15 mm and does not respond to low.current highways and cables with double insulation.

Touch with a hammer

The technology is used in the performance of short furrows or urgent repair. The boundaries of the canal are applied to the wall, and then cut through the grooves with a chisel, manually adjusting the depth and intensity of the tool feeding. The technique is not used when cutting brick partitions, shock loads violate the monolithic monolithing and cause partial or complete collapse of the wall.

A chisel with a drill

To obtain a furrow, it is necessary to drill a series of holes with a diameter of 10-30 mm (in accordance with the width of the groove) with a step of 15-20 mm located along the line line. The remaining jumpers are knocked out by a chisel, the resulting canal has uneven edges and uneven depth. The disadvantages of the technology are low labor productivity, the inability to perform grooves in the brick walls and a large amount of dust and dirt thrown into the room with an instrument.

Corner grinder

A corner grinding machine with an abrasive circle allows you to cut various building materials and does not create shock loads on the partitions. After performing parallel incisions, the central part is knocked out with a chisel. The disadvantages of the methodology are noise, dust that enters the room, uneven depth of cutting and risk of instrument breakdown. Some masters modify the equipment, installing a double circle and a protective shield with a pipe to connect a flexible vacuum cleaner hose.


For cutting the furrows in the infantry cartridge, a special nozzle (for example, drill or spatula) is installed from high.strength steel. Then the master passes the tool along the marking lines, but the resulting grooves have an uneven section. To improve the quality of work, it is necessary to pre.drill holes, and then knock out the jumpers with a spatula.

The technology is not used on brick walls, but applicable to concrete partitions.


The highest quality cutting of the grooves for electrical wiring is achieved when using a special tool with an electric drive and a window for removing dust by a construction vacuum cleaner. The equipment is equipped with ergonomic handles and a vizier that allows you to lay grooves along the intended lines. The design of the stroborez provides regulators for changing the depth and width of the groove. After cutting, it is necessary to knock out the central part of the furrow with a thin chisel, the grooves have even edges and the correct geometric shape.

Corner grinder with a peorator

Since a special tool is highly price (from 5.5 thousand. For budgetary models of Chinese production), then for repair they use a set of corner grinding machine and a peorator. After marking the walls, the grooves of the required thickness and depth are cut out, and then remove the material with a steel spatula, clamped in the cartridge of the penetrator.

It should be noted that with cutting, fine dust is thrown into the air, work must be performed in a respirator and protective clothing.

Details for stroke of walls with your own hands

The technology of cutting the furrows in the walls for laying wiring depends on the tool used. The owner of the premises chooses the method, focusing on the volume of work and the available equipment. To accelerate the procedure, it is recommended to purchase budget trobostera or rent a tool (costs will pay off a decrease in the pollution of the room and reduce the consumption of gypsum plaster necessary for sealing channels).


For cutting the furrows by the ashorator, you need:

  • Install a drill in the cartridge and enable power. If the room is cut off from the camshaft, then you will need to preliminarily draw a separate circuit with a socket connected to the metering device and fuses in the box on the stairwell.
  • Drill a chain of holes along the marking line with a step of 10-20 mm, the depth of the channels does not exceed 25-30 mm. The diameter of the drill for drilling must be selected depending on the width of the groove.
  • Remove the drill and install a flat shoulder blade (STROBER), switch the peorator to a stress mode without rotation.
  • Close the jumpers between the holes sequentially. It is necessary to take into account the risk of peeling large fragments of the outer layer of plaster on the edges of the furrow.
  • Install the nozzle for cutting cylindrical niches for sockets and switches in the cartridge.
  • Put the peorator into rotation mode (a combination of shock loads is allowed) and drill grooves at the planned points.
  • Knock out the central part with a flat spatula (if necessary, remove the remaining protrusions in the depths of the niche).

If an angular grinder is used to carry out the work, then the following actions should be performed:

  • Install an abrasive disk and make a cut in the wall in accordance with the marking line.
  • Cut off a parallel groove located at a distance equal to the width of the furrow.
  • Remove the resulting dust from the room, and then knock out the central part from the groove with a pedorater or manual tool.
  • Delete the protruding material on the lower surface of the furrow.
  • Perform holes in the walls for installations of sockets using a crown, clamped in a peorator cartridge. It should be noted that knock out a chisel or cut through the angular grinding machine cylindrical channels will not work.


To obtain the furrows with an electric strobes in a partition laid out of brick, it is necessary:

  • Install the discs on the required width and depth of the furrow.
  • Connect a flexible sleeve with a protective casing with a building vacuum cleaner.
  • Connect the power cable to the outlet located on the vacuum cleaner (to ensure a synchronous start and disconnect the device with a delay for removing dust from the working area).
  • Attach the stroobores to the wall and press the power button.
  • Cut out the grooves, determining the direction of the furrow through the vizier.
  • Install a metal blade in the cartridge and knock out the central part of the groove.
  • Drill holes with a crown in the walls for installing distribution boxes, switches or sockets.


According to the PUE standards, the laying of wiring in combustible structures is not allowed, but some owners neglect the rules and put cables in wooden partitions in a metal corrugated sleeve. To get the grooves, use a handmade tool, circular saws or an electric milling cutter, which is moved along the guide bar fixed on the wall. The complexity of the sealing in the wall should be taken into account, since putty differs in structure and color from the main material.

Gas blocks and foam concrete

Such building materials are characterized by reduced hardness, therefore, to obtain grooves, you can use a manual device with incisors:

  • Make sure that there are no values ​​of the valves of the reinforcement used to enhance the design of the walls.
  • Install a cutting element with the required width on the tool.
  • Stretch the device along the drawn line with force.
  • Repeat the operation several times, seeking to obtain a groove of the required depth.

To accelerate the procedure, an angular grinding machine with an abrasive circle can be used, but during cutting a large amount of fine dust forms. The master needs to use protective clothes and respirator. It is allowed to use an electrical furrower connected to an elastic sleeve of a vacuum cleaner.


Cutting grooves in gypsum sheets is not carried out due to the small thickness and fragility of the material. Cables are laid in protective sleeves at the stage of building the frame, and then removed through the openings pre.drilled in the sheets. For drilling channels, a cutter is used in a cartridge of an electric drill or an electric screwdriver (using a percussion tool is prohibited). Additional wires are extended behind the sheets of drywall using a wire (taking into account the location of the profiles of the metal frame).

Monolithic walls

Cutting monolithic walls in houses is prohibited, since the furrow violates the strength of the structure and leads to cracks. Permission to such work is issued by an expert commission on the basis of a project analysis approved by the architect of the building. Since the probability of obtaining a positive answer is small, the owner of the apartment needs to develop a wire installation scheme in such a way as to exclude the passage of cables along the supporting partitions.

Under the air conditioning

The standard split system consists of an apartment module and an external heat exchanger, which are connected by metal tubes for the circulation of a refrigerant. For laying highways, a furrow is required with a width of at least 60 mm at a depth of 50 mm. The groove will lay the tubes wrapped in a layer of thermal insulation, power supply cables and control. It is also necessary to take into account the channel for the drain of condensate. The furrows are carried out by installers engaged in the installation of air conditioning, preliminary independent cutting of the grooves is not recommended.

Is it possible to post the walls and ceiling

Federal and regional norms prohibit the stakes in supporting structures. Weakening of the cross section leads to loss of strength, as a result of which the building or part of it may collapse. To lay a cable on the ceiling, you need to look for another method. There is no point in the touches of the crossbars: they are closed with decorative pads, behind which it is convenient to place wires.

In SNiP 3.05.06-85 there is a reservation allowing to perform furrows in supporting structures in case of coordination with the author of the project. In reality, this is almost impossible to do.

The device of the furrows in the partitions is allowed.

The legislative framework

According to Art. 7.21 Code of Administrative Offenses, stroke of supporting structures is qualified as illegal redevelopment. The housing inspection will force the offender to make the following:

To fulfill the second requirement, lay the penalty not enough with a solution. The bearing capacity of the structure will not be restored from this. It will be necessary to take special measures in accordance with the strengthening project. Only the author of this building has the right to develop it. this is written in law. For such a service, they can ask for up to 800 thousand.

In case of failure to fulfill the instructions of the housing inspection, the apartment by decision of the court may be put up for auction (p. 5 tbsp. 29 LCD).

Norms and restrictions

For horizontal stroke in the partitions SNiP 3.05.06-85 sets the following maximum permissible parameters (mm):

Vertical furrows are made without restrictions.

Minimum distances from the fine to structural elements (cm):

The device of the stratum diagonal is prohibited. They are made in parallel corners of the building.

The furrow for the wire on the site from the camshaft to the electric shock can only have 1 turn.

Specific features of stroke

Next, we will consider in detail the stroke of the walls from different materials.

How to make strokes in wood

For wooden walls, all of the above tools are suitable with the exception of the peorator. Instead of a chisel, it is better to apply a chisel, but the principle of work remains the same. Create two parallel cuts at the same distance and remove the wood between them using a chisel. specific tools can also be used:

  • The circular saw allows you to make even strobes, but a high skill of ownership of the device is required. The principle is based on repeated passages with circular and gradual expansion of sawing to the desired width.
  • A handmade cutter allows you to create a neat groove. To do this, they attach a guide bar to the wall and a tool is carried out along it, making an even deepening. Then it expands to the desired width. For such work, a special cutter is often used, but you can cope with the usual nozzle forming the groove.

Thus, tools for stroke of wood are greater, as well as the ability to do this. Ideally, you need to choose one of the listed tools, since they are designed for wood work.

How to make grooves for wiring in aerated concrete

Ideally, you should use manual trobores for aerated concrete, since blocks are easily lend on such processing. The tool is a metal tube with a handle and a protrusion on the other side. It is simply in use, leaves behind a minimum amount of dust. Alternative. the use of a circular saw or corner grinder angular grinding, but you will need good protection for the respiratory tract.

There are certain nuances. Walls from aerated concrete or foam concrete blocks often contain reinforcement, so the process of their stroke requires a special approach. Before making the recesses, make sure that your actions will not lead to a decrease in the strength and integrity of the structure.

Carpic walls

If you need laying wiring in the house without finishing on the walls, then usually they do not engage in stroke. Instead, a flat cable with the desired section is installed on the brick wall, after which it is hidden under a layer of plaster with a thickness of 30 mm. This is enough to hide the 3 × 2.5 or 3 × 4 cable. A larger wire is used much less often.

Strokes of walls, if necessary, are carried out by any of the listed tools. The process is identical to the creation of recesses in concrete walls. However, the brick is softer and better lends itself to processing.

Hypsum cardboard stroke

Drywall sheets are very thin, so it is impossible to make strobes in them. Typically, the cable is hidden under the fragile structure of the sheet, and the only option could be drilling the holes necessary for installing a socket or a seat under the circuit breaker. This is done using a peorator.

Strob in the tile

Tiles are often used as a finish in the bathroom or in the kitchen. Often there is a need to make a stroke in the wall. And there should be no problems in this regard: the only nuance. it is required to install special diamond circles on an angular grinder or a strobore. To exclude the formation of cracks in tiles, avoid the use of the penetrator.

Nuances with load.bearing walls

Before performing the repair associated with the laying of a new or replacing the old electrical wiring, you need to draw up a project. Entertaining documents will be required, which indicate the location of the load.bearing walls and the possibility of making depressions in them. The resulting plan clearly indicates where, where and how to lay a cable, what width and depth should there be strokes, etc. D.

If you have doubts about the appropriateness and admissibility of making a stroke in the bearing wall, then try to get the appropriate permission in BTI. The organization engaged in the design of the house will provide all the documents and clarify the margin of strength of the building. The resolution will be issued in most cases.

Stroke of walls for air conditioning

Particularly dimensional cables are required to install standard air conditioners consisting of internal and external blocks. The width of the strobe should be at least 60, depth. 50 mm. This will allow hiding all copper tubes with insulation materials, wires and corrugation used as a removal of condensate.

How to mask the strokes with wiring

As soon as the strobe is made, and the wires are laid, you will have to close the groove and go to the final decoration. The process is quite simple:

  • The recess is cleaned of dust and dirt using a construction vacuum cleaner or broom.
  • The surface of the groove is covered with a layer of soil. This is done with the help of an ordinary brush.
  • Wait when the primer is finally polymerized.
  • Moisten with water before sealing.
  • Lay the recess using plaster or mounting foam.

In residential apartments, hidden laying of electrical wiring is almost always used, and it is best to implement this method by making a strobe. However, this process is not as simple as it seems at first glance: prepare in advance, having selected all the rules and recommendations, renting or taking your friend’s suitable tool depending on the material from which the walls are made.

Do not forget that such recesses can not always be done: for example, do not even try to work with a peorator on walls covered with drywall sheets. If there are doubts, then it is best to contact a professional specialist.

How to make a strooboresis of corner grind

The tools are distinguished by the presence of a casing with a vacuum cleaner and an elongated spindle. The corner grinder has no these elements. However, when performing one.time work, you can independently modernize the device. It is more profitable than buying ready.made gap.

Production of a protective casing

With your own hands, you need a profile pipe, a medium.diameter pan, a thin metal sheet, a clamp. The size of the latter should correspond to such a factory casing of the corner grinder. It is also necessary to prepare a plumbing challenge and a slope with a diameter of 1.25 inches.

  • Make a sole from a profile pipe. It is cut along, halves are welded perpendicular.
  • 2 plates are formed from a metal sheet, which are welded to the sole.
  • Cut a pan, making a casing like a casing from it. A hole is formed in the bottom with a diameter that coincides with that of the standard part.
  • Weld to the design of the clamp. Cut off part of the pan located below the hole. Cut an amplifier from a steel sheet, weld the part.
  • Cut the metal sidewall. Weld the element to the pan.
  • Cut the pipe from the catch, which is welded to the hole in the housing of a homemade casing.
  • Put on a plumbing tap on the previously attached element. The internal gasket provides a solid landing, the possibility of turning in different directions.
  • A hole for the handle is formed in the upper part of the pan. It is fixed with a bolt.
  • Insert rollers into the sole, which are fixed with washers.

Sprinking depth regulation

The device that changes this parameter is made from a simple screw. When rotating, the element lowers or raises the platform, which is why the discs are more or less.

So that the settings do not get down, the screw is fixed with a countrogike.

Installation of disks on the shaft

To fix the parts, you will need a clamping nut. Before installing two discs, the puck is removed from the spindle, grind it. This will help to fix another 1 clamping nut.

First mount the first disk, then the puck, then the second circle. The structure is fixed with another nut. The finished gap is placed in the casing, to which the hose is connected from the vacuum cleaner.

Shtroting for air conditioning

The classic split system includes 2 modules: one is mounted from the side of the street, the other on the inner surface of the wall. To accommodate cables and tubes, a channel 6 cm wide is made, 5 cm long. After laying communication, hidden under a layer of gypsum solution, plastered the wall.

The appearance of particles of plaster, concrete, brick in the air complicates the work. Therefore, you should think about how to get rid of dust.

The easiest way is to regular moisturizing the walls.

Dust capture for corner grinders

In the manufacture of a home.made casing, the casing is connected to an industrial or household vacuum cleaner. The case overlaps both disks, isolates the processed surface. Division pulls dust, preventing it from entering the air. Another effective way is to connect a hose that continuously supplies water to the wall. However, in this case, caution is observed, since the moisture falling on the tool disables it.

Stroke of the wall for wiring

The stroke of concrete and brick surfaces is necessary for communications. In such prepared trenches, wiring or water supply pipes are laid on the walls. The process is associated with serious dismantling work. A specialist can conduct them on supporting structures and ordinary interior partitions. To get the highest quality result, it is necessary to entrust this work to a professional.

You can find a good repair master using our site. We publish ads from specialists with extensive experience. They come to a call with their tools and are most responsible for work.

Shtrust is carried out taking into account the project of communications. Masters take into account how and where the network will be laid, and at what depth to make a strobe. The width is taken into account. This is very important for the accuracy of actions and minimal surfaces.

Masters apply preliminary marking of communications. After a special electric tool, the material is cut to the desired depth, and then the contents are removed from the intended areas. So the sections are even, the surface is less damaged.
