When carrying out repairs in their house or apartment, owners usually face a stage when it becomes necessary to lay new electrical wiring. This is necessary for installing new sockets, because there is simply not always power supply in the intended places for their placement.
You might think that to complete the task you will only need to purchase a branched wire, and also use the help of specialists. However, the services of craftsmen today are not free, moreover, they can turn out to be very expensive, while you can quite easily dabble walls yourself. To do this, you will only need to study the technology and correctly apply it in practice.
Features of slitting a concrete wall
If you are thinking about the question of how to groove the walls for wiring, then at the first stage you need to use a pencil and paper. Your task is to schematically indicate the line of passage of the wire. It is important to determine the exact locations of sockets and switches. To do this, you need to familiarize yourself with the set of rules that govern the distribution of electrical equipment.
Many people believe that they know the gating technique, but in practice they encounter problems. If you are faced with the question of how to properly groove walls for wiring, then you should know that horizontal grooves should not be located further than 150 mm from the covering slabs. Vertical furrows should be abandoned, as for the case when they can run about gas pipes. It is necessary to retreat from the latter by at least 400 mm.
Windows and corners should be removed by 150 mm or more. Pipes must only be laid vertically or horizontally. There should be no unnecessary bends. The only exceptions are attic structures; here the wiring should be located parallel to the wall - at an angle.
When home craftsmen wonder how to properly groove walls for wiring, they learn that the length of a continuous groove should not exceed 3 m, while its width and depth are 25 mm. It is important to exclude the presence of turns. The transition to the outlet and switch should be done at the same angle. The exception is joints that have a horizontal surface. It is prohibited to do this in load-bearing walls grooves located horizontally. This recommendation applies to buildings in any region. When it comes to panel houses, this rule should be followed.
Tool selection
Before starting work, you should definitely ask yourself the question of how to groove the walls for wiring. Today there are a huge number of ways to carry out these manipulations. You can use:
- perforator;
- wall chaser;
- chisel and hammer;
- grinder;
- impact drill.
A wall chaser is an almost ideal tool, as it allows you to get even cuts. However, its cost is high. But if you plan to use a hammer drill, then the manipulations can be carried out very quickly, and the work will have a low cost. With the help of an angle grinder, such furrows will be smooth, but debris will form that is difficult to get rid of. The main advantage of the chisel and hammer is its low cost. However, if you want to achieve high quality, then you should not skimp on tools.
Using a hammer drill
You may be faced with the question of how to drill walls for wiring with a hammer drill. This method is one of the most common. This is because the procedure does not require a lot of money and time. The first step is to prepare the walls. These works are no different from those when other tools are used.
The technician will have to check for old electrical wiring. When there are wires in the walls, unpleasant moments occur. You should not risk your health and life. You need to use a special device for checking. At the next stage, the master will have to mark the walls. However, you need to start marking only after you have made sure that there are no live wires in the walls.
From the central box it is necessary to draw lines to current sources, among them:
- sockets;
- switches;
- lighting wires.
It is necessary to ensure that there is protection from dust and dirt. Doors and windows are usually covered, because using a hammer drill will generate dust that will spread throughout the room. If you are faced with the question of how to properly tap a wall for wiring with a hammer drill, then you should read the information below. After completing the preparation, you can begin the main actions.
To do this, using a tool, you need to drill holes along the drawn lines, which should be 1.5 cm apart from each other. Then everything depends on the tool. It can be switched to the gating mode; for this you should use a special attachment. You can also insert a simple drill. The pre-drilled holes are connected to each other using a hammer drill. Beginners should not neglect preparation, because without experience such work is quite difficult to carry out, and achieving an ideal result will be completely unrealistic.
Using a grinder
If you still haven’t decided how to groove the walls for wiring, then you can consider a technology that involves the use of an angle grinder. To do this, you should take advantage of the fact that the wall material is quite durable. Two strips should be cut on the marked area. The slots should be parallel. The step between them will be 2 cm.
Next, a hammer drill or other tool is used to remove unnecessary residue between the cuts. You can use a hammer drill. Afterwards, the wiring is laid in the opening and covered with plaster. Excavation of material should be carried out to such a depth that final stage It was convenient to lay the plaster. When the wires are completely hidden and located deep, there will be free place, which can be easily filled with the composition.
If you are faced with the question of how to ditch concrete wall under the wiring, then you should also think about how to avoid the formation of excessive amounts of dust. After completion of the work, its layer may turn out to be so impressive that only an industrial vacuum cleaner will be able to clean the room.
If you are interested in cleanliness after completing the manipulations, then you should prefer a wall chaser. It resembles a grinder, but has built-in diamond wheels. The presence of a casing allows you to adjust the pitch between the discs and control the depth of the furrows. The advantage of the wall chaser is the presence of an outlet pipe for the vacuum cleaner. During operation, dust does not extend beyond the casing. However, this method is not suitable for one-time work, because you can purchase the tool for high price. But if you still want to get clean room, then you can rent the unit.
Using a Hammer and Chisel
When wondering what to use to make walls for wiring, you can consider one of simple options- use of a hammer and chisel. The length of the section to be grooved should be divided into separate segments. Using a chisel, the master will have to mark the recesses; the marks should be located along the edges of the future groove. The recesses should be equal to the width of the tool tip. After installing it across the direction of the future cable, part of the wall must be knocked out.
Continue deleting upper layer further follows. You need to move along the intended line, and at the end you can deepen the groove by 25 mm along the entire length. After each removal of the top layer, you can deepen the groove immediately. However, these tools cannot be used if the wall is concrete, since the underlying material is quite strong, so it will be difficult to work.
Final works
So, let’s tap the walls for wiring without dust using special tool- a wall chaser, which you may have in stock. Sometimes you can find an instrument from relatives or friends or rent it from a store. Once the grooves have been punched, they should be cleaned with a broom or vacuum cleaner. It is important to remove dust from the recesses and prime them.
The process of laying electrical wiring and fixing it has a number of nuances. After completion of the work, this can be done, as mentioned above, using plaster. As alternative solutions putties and plaster are used.
Why you shouldn't choose a hammer drill
Before starting work, you may ask a question about how deep to groove the wall for wiring. Using a hammer drill, you need to go deeper by 25 mm. Using a spatula, at the next stage you can start constructing the groove. The main condition in this case is not to install the blade across the line. In this case, you will break off an extra piece of plaster or wall. As a result, the groove will not obtain the required width and depth parameters; in addition, appearance won't be very attractive. Scoring with a hammer drill allows you to achieve results, but the process itself is not very clean and fast.
Why you shouldn't use an angle grinder
If you, too, were among those who wondered what is the best way to tap walls for wiring, then you have probably considered options for using an angle grinder. Additionally, you should purchase for it diamond blade. With its help, you can cut not only brick and concrete, but also plaster. In the latter case, the work will be easy.
The whole process will be almost identical to the previous one, with the only exception being the result, which involves the formation of a more even groove. This is important to consider when minimizing damage to wall finishes or plaster. However, experts do not recommend using an angle grinder, since working with it is accompanied by the formation large quantity dust, which fills the room completely upon completion. But to solve the problem, you can use a vacuum cleaner, it is better if it is industrial. When cutting, in this case, you should enlist the help of another person who will hold the suction pipe near the cut point.
For reference
Now you know how to groove walls for wiring without dust - for this you should use a wall chaser. It acts as an ideal modification of the option with an angle grinder. The device provides the ability to install a pair of cutting blades. You can adjust the distance between them. The main advantage is that the circles are covered with a casing that covers the point of contact with the wall.
Conclusion
In most cases, the wall chaser has a casing that is equipped with an outlet for the suction pipe of the vacuum cleaner. The result of the work is smooth grooves that can be formed without dust. After cutting along the edges of the groove using a hammer drill, you will need to select excess material.
Grilling monolithic walls- question special order. The installation of grooves in the walls, floor and ceiling is carried out for the installation of communications: electrical wiring, pipelines, etc.
As a result of a rather complex process, long grooves of varying depths are formed on the plane, depending on the communications being carried out and the possibility of the walls.
1. Lurking danger
A crack in monolithic walls can pose a direct danger to the structural part of the building. Feature monolithic construction is that all monolithic walls of the building participate in a single structure and are load-bearing. They are all connected reinforcement cage And concrete mixture. With such components, any violation of integrity is especially dangerous.
Improperly executed fines cause the destruction of the wall, and this weakens the structure of the entire building. In the short term, such defects will most likely go unnoticed, but in the event of emergency situations their consequences can be disastrous.
Therefore from similar works should abstain. However, if a balanced and well-founded decision on gating has been made, and the appropriate permits have been obtained, only specialized organizations need to be engaged to carry out this work.
In order not to make a mistake in your choice, you should definitely check whether the company has the appropriate permit (license) to carry out these works, make sure that necessary equipment and worker qualifications.
It is definitely worth remembering that the penalty in monolithic floors(floor and ceiling) is strictly prohibited.
2. Cleaning the ceiling or what to do if you need to move chandeliers
Often the wiring installed during the construction of a building does not meet the desires and needs of the occupants of the apartment or office. For example, you need to install additional lighting, or change their location on the ceiling.
The simplest, but not very aesthetic option is to run cables over the existing ceiling in special channels - cable glands. If appearance matters to the owner of the premises important role, then it is best to abandon this method.
The next option is to lay the cables outside and hide them by plastering the ceiling. It's painstaking enough hard work for master finishers and a very expensive pleasure for the owners of the premises.
The third way is to hide the cables under a plasterboard ceiling, or under another form suspended ceiling. Here the work will not be so long and “dirty”, but you won’t be able to save money.
Fourth option - stretch ceiling. Thanks to advances in the modern construction industry, it has become possible to quickly (from several hours), practically without noise and debris, not only hide communication wiring, but also get a beautiful and flat ceiling. Its cost, as a rule, does not exceed the summed costs of installing any of the above methods to disrupt wiring. Moreover, during operation you will not have to spend money, time and effort on cosmetic repairs.
3. What to do with walls
For the production of fines in the walls, the rules are not so categorical. Subject to permission and necessarily competent specialists equipped with the necessary production facilities, taking all precautions and building codes these works can be carried out.
The stripping of monolithic walls is carried out in compliance with the following conditions:
- grooves are laid exclusively horizontally and vertically, strictly according to the level;
- scratching the wall diagonally is strictly prohibited;
- the distance from the supporting structure of the ceiling for a horizontal groove is 150 mm, 300 mm, 450 mm and so on;
- for grooves having a vertical direction, indentation from corners, window and doorways- from 100 mm;
- distance from existing or proposed project gas pipes should not be less than 400 mm.
In addition, the dimensions of the grooves and their trajectory must be observed. On walls up to 80 cm thick, a groove for wiring is arranged along the shortest path, observing the principle of horizontal and vertical. If the thickness of the wall exceeds this indicator, then the fine is carried out along the construction lines.
Limit sizes of fines:
- length - 3 thousand mm;
- depth - 25 mm;
- width - 250 mm.
A complete list of mandatory conditions is contained in the relevant SNiP. The specialized companies are well aware of all the norms and rules provided for by them, strictly observe them, which ensures safety during the work and further operation of the building.
Shredding is a type construction work, which is performed when it is necessary to install electrical wiring and other communications. It involves making special recesses (grooves) in the walls using special equipment. Grilling - complex labor-intensive process, which requires the involvement of highly qualified specialists. Poor quality performance of this work can lead to deformation of load-bearing structures, damage to communications and the creation of an emergency situation, including the collapse of the house.
SNiP for gating walls for electrical wiring
Wall gating according to SNiP requires a certain preparatory work. Before you begin laying recesses, you need to familiarize yourself with the layout of existing communications and check their location using special equipment. This is necessary in order to prevent damage to pipes, cables and wires, as well as to eliminate the possibility of injury to workers.
SNiP for gating load-bearing walls
Grilling load-bearing walls according to SNiP requires compliance following rules:
- recesses (grooves) must be laid either vertically or horizontally; diagonal grooves are strictly prohibited;
- horizontal recesses can be made no closer than 150 mm from the ceiling;
- vertical recesses - no closer than 100 mm from windows, doors and corners;
- if the groove is planned to be located parallel to the gas pipeline, the distance between them should be at least 400 mm;
- The dimensions of the groove must not exceed the following restrictions: length - 3000 mm; width and depth - 250 mm;
- on walls more than 800 mm thick, recesses must be laid along the shortest path;
- on walls less than 800 mm thick - parallel to the building lines.
These are not all SNiP standards for wall gating; there are other rules that must be followed when performing this work.
The RezAlmaz company provides electrical wiring in accordance with SNiP and will provide you with complete safety. Our specialists have great experience And highly qualified. We use modern reliable equipment, so you can be sure of high quality services provided.
If you have purchased a small one-room home and decided to carry out a major redevelopment, you will have to do the gating of the walls for wiring yourself. This way you can replace outdated electrical equipment, arrange power points in a new way, or create the functionality of the room that you need.
Even the most inexperienced owner can carry out the work independently, provided that certain principles and rules are followed.
Permission to groove a load-bearing wall
If there is a need for minor redevelopment studio apartment the question will arise: is it possible to ditch the walls in panel house as simple as in brick? BTI categorically prohibits both private individuals and commercial organizations from carrying out this type of work.
Redevelopment in a panel-type apartment requires approval from the relevant authorities (the same BTI). State organization will approve or reject your actions in terms of safe operation living space.
When performing gating, even minimal damage to the supporting structure poses the risk of a subsequent collapse of the entire structure, not only for you, but also for all residents of the house.
How to properly tap walls for wiring: rules, principles
In order to carry out repair work in small apartment with minimal labor costs, first of all you need to prepare the necessary tools.
Although a professional wall chaser creates the necessary channels for wiring quickly and smoothly, its cost can be prohibitive for many. Therefore, it can be replaced with a more affordable tool - a hammer drill.
Necessary tools and means for wall gating:
- hammer drill with a slotting attachment;
- chisel and hammer;
- respirator;
- protective glasses;
- work gloves.
Stages of work
Before starting work, close the entrance to the room protective film so that all construction dust settles only in the room involved in the repair.
First of all, when grooving the surface for wiring, it is necessary to apply the planned markings of the future location of electrics and sockets on the wall itself, taking into account all the wishes.
Before you start work, transfer a drawing of the future location of the electrical wiring onto paper. This will be useful to you in future repair work or any network fault.
If the markings have been applied to the walls, you can begin to work: along the marking line, using a hammer drill in drill mode, we form holes along the entire line of future grooves. We make holes at a distance of two centimeters from each other and to a depth of 2-3 cm each.
After the preparation of the grooves is completed, we switch the hammer drill to the jackhammer mode, change the drill to a jackhammer and carefully knock out pieces of concrete along the line of the formed holes, forming the necessary grooves. Having completed the gating, we lay new wiring in the grooves and plaster the walls.
If the work is carried out using a grinder, then a diamond-coated disk is used. To obtain an even groove, it is necessary to slowly and with pressure move the rotating disk of the grinder along the intended line, deepening it by the required amount.
It is worth remembering that the grooves for wiring should only be positioned vertically or horizontally. Diagonal wiring is prohibited.
Grooving the wall for pipes and sockets
If, during repair work, it becomes necessary to groove the walls for a socket, then in this case it is necessary to purchase a special concrete crown, which is inserted into the hammer drill.
You can tap walls for plumbing in a house using the same principle as taping for wiring. The only difference is that the depth of the groove will be greater (up to 5 cm).
When choosing a crown, pay attention to its purpose. When purchasing a crown for drywall, it will not be able to overcome concrete or brick with its help.
Manually chipping walls is a labor-intensive process, so it is better to use a power tool. With its help, you can complete a large amount of work in a short time. Remember the rules for operating electrical equipment.
You can create a groove, that is, a groove in the wall where electrical cables will be hidden, on your own. However, here it is important to comply not only with the rules for conducting the operation in question, but also with the general construction legal framework. The article discusses the features of the operation, tools for its implementation and various ways carrying out work.
How to hide communications in the wall?
Installing new wiring is an integral part overhaul. In addition, there is often a need to add new sockets and switches in the room or around the entire perimeter of the home.
In any of these cases, it is impossible to do without performing the operation of wall slitting.
What is wall gating
Wall chipping is cutting through walls using specialized electrical equipment for various needs. One of the most striking examples of a case where such an operation may be necessary is the gating of walls for the purpose of laying wiring.
The groove gasket is intended for laying electric cable or other communications and objects that need to be hidden. The operation is accompanied by the formation of a large amount of dust and dirt, and also requires the use of special tools.
Do-it-yourself wall cutting for electrical wiring
Before you start crumbling the wall, you should plan and draw a diagram of the future wiring, taking into account all the associated objects: sockets, switches, and so on.
Doing wall slitting with your own hands is a real task for home handyman. This operation can be carried out either using special electric tools or manually.
There are several methods of gating, which will differ depending on the chosen tool:
- Hammer and chisel.
- Hammer.
- Bulgarian.
- Wall chaser.
Each option differs in its level of complexity and the amount of effort and resources expended. In addition, the time spent and the quality of the final result differ. If desired and possible, it is permissible to use other tools.
Is it possible to groove load-bearing walls in a panel house?
Due to the increase in the number of electrical appliances, many residents panel houses They are looking for ways to hide wiring not under baseboards, but in the walls or ceiling.
As a rule, in most panel houses, the walls of the panels are load-bearing and it is prohibited to ditch them. If the wall is not load-bearing, then you should make sure that the work being carried out will not upset the balance of load distribution on the walls and ceiling and will not lead to the destruction of the structure.
Before you begin laying electrical wiring directly into the walls panel house, you should first familiarize yourself with the floor plan of the apartment. Walls that serve as stiffeners can be tapped, but those that serve as load-bearing walls are strictly prohibited.
Monolithic house
Load-bearing walls in monolithic house As a rule, it is impossible to ditch. This is due to the fact that if the integrity of the wall is damaged, this can directly affect the construction strength.
Brick walls
Due to the fact that brick laying is carried out using a cement-sand mixture, when chipping brick wall There are no special problems. Using a hammer and chisel, you can knock out this mixture manually, and the gap formed between the bricks will serve as a groove for the cable. Of course, after all the work is completed, the groove will be covered with plaster.
In order to preserve the strength qualities of the wall, it is recommended to crush the surface of the brick wall only in the horizontal direction according to the seams between the bricks.
Grooving walls for wiring: options, the better
For each individual case, tools, groove directions and other features may vary. First of all, the choice is influenced by the type of building and walls that are located in the desired room. In addition, the size of the groove has an additional influence.
A hammer drill with an attachment is a tool for punching walls
A hammer drill is used for punching walls, as a rule, when only one of the rooms is being renovated. This is due to the fact that the wall chaser produces specific dispersed dust, which penetrates everywhere and can spoil things and furniture.
To groove with a hammer drill, you need to drill holes with a diameter of 8 mm along the marked route. The distance between these holes should not exceed one centimeter. After this, a special attachment for gating is put on the hammer drill, and the device is switched to impact mode. Next you will need to punch a groove between the intended holes.
Works with an angle grinder
You will first need to mark the future location of the cable. After the marking has been completed, you can begin to create gutters. Using an angle grinder, this can be done in two ways:
- The work is carried out with a grinder, which is worn special disk, designed for cutting concrete.
- At a distance of five millimeters, two cuts are made parallel to each other. And the groove itself is hollowed out with a hammer drill.
Drill attachment
A drill can also be useful in solving the problem in question. Will need to use electric drill, supplying it alternately with a drill, an attachment with a short drill and a special spatula.
First of all, using a drill or a nozzle with a drill, you should drill holes with a depth of at least 25 mm and at a distance of 10-15 mm from each other. The next step Using a nozzle in the form of a spatula, a gutter is constructed.
Shovel for work
Knock out a groove required sizes, according to the markings applied in advance, can be done using a spatula. The blade is directly an attachment for the hammer drill, which creates and deepens the groove according to the cuts marked in advance.
Among the advantages, one can highlight the fact that the depression is formed quickly, and its edges and shape will be smooth, which will not require additional manipulations. Among the disadvantages is that using a spatula can provoke great education dust.
Is gating possible without dust?
Those who are interested in the question of whether it is possible to tap walls without dust may receive a positive answer. This becomes possible when using a specialized wall chaser equipped with powerful vacuum cleaner. Dust that is generated during operation will fall into a special chamber, which prevents it from penetrating into the surrounding space.
Rules
The operation in question is performed according to the rules:
- Grooving for wiring should be done parallel to the main structures of the building, vertically or horizontally.
- Horizontal grooves should be carried out with a distance of at least 150 mm directly from the floor slabs.
- The furrow during vertical movement should be 100 mm away from doors, windows and corners, and 400 mm from gas pipes.
- The length of the groove should not exceed three meters, and the width and depth can be no more than 25 mm.
- IN load-bearing structures It is not recommended to make horizontal furrows.
How to quickly drill under a cable or sockets
The right tool makes it possible to quickly drill a wall for a cable or socket. The choice should be made according to the material of a particular wall, its characteristics and location. Fast and convenient option is to use a hammer drill or impact drill, but in this case the groove may turn out uneven.
To what depth is it prohibited to ditch in load-bearing walls?
In the case when gating is carried out in load-bearing walls, the depth should not exceed 20-30 mm.
At this depth, as a rule, reinforcement is located, damage to which can not only have catastrophic consequences, but also constitute a violation of legal norms.
How to make a groove
Regardless of the chosen work option, general order The actions will be general and are presented below:
- Marking and surface preparation.
- Carrying out work.
- Ending.
Is it necessary to carry out work before plastering?
After carrying out work and laying the cable, dust and dirt remain in the ditches, which interfere with the quality adhesion of the primer to the wall. Armed with gloves and a wide brush, you should apply a generous layer of unevenness in the wall along its entire length.
How to properly groove a wall for wiring and sockets: progress and sequence of work
The stages of work will be as follows:
- Drawing up a plan on paper and drawing contours with markings on the wall.
- Cleaning and preparing the work area.
- Carrying out a work operation.
- The final stage, cleaning.
brick wall
You can easily and quickly make cuts on a brick wall according to the intended lines using a hammer drill or grinder.
Concrete partitions
To perform this action, you will need a hammer drill, a shovel, and also a concrete drill.
Options for how to hammer a concrete wall with a hammer drill without a lot of dust
To avoid the formation of large volumes of dust, you should cover the room with film and humidify the air before starting work. It is also recommended to crush the wall surface according to clearly marked contours.
How long does gating take?
The time required for the operation under consideration directly depends on the chosen method, tool, groove dimensions and characteristics of the wall material.
The article discusses all aspects affecting the concept of the gating operation, its features and rules of implementation.
