Making repairs in the apartment or house, each owner faces a stage where we have to lay new wiring. This is done in order to install a new outlet, as alleged in their places of accommodation no power. It would seem, bought a branched wire, invited professional and be done with it. But the wizard is not free, and stroebe of walls under the wiring and you can own. Enough to carefully study the material and correctly apply it to practice.
How stroebe concrete wall ↑
Before starting, take a sheet of paper and pencil to schematically represent the passage of wires, the exact location of switches and sockets. It is recommended to familiarize yourself with the rules for distribution of electrical documents 3,05 06-85 SNiP. Many people believe that know how stroebe, but in fact, the unfamiliarity with basic, at best, puzzling electrician-Amateur. It is better to read the main points and get the job done efficiently. Below are 6 key requirements that need to be followed:
- Don’t spend horizontal chasing more than 150 mm from overlapping plates.
- Beware of the vertical furrows near the gas pipes. The distance should be not less than 400-450 mm. the Corners and the Windows should be placed at least 150 mm.
- Stroebe walls only horizontally or vertically. Ideally, there should not be unnecessary slopes. An exception can only be design of the attic: here the transaction is placed parallel to the wall under the slope.
- One continuous length of furrows should not be more than 3 meters, and the depth and width is 25 mm.
- As well as tilts, bends should not be. The transition to the switch and the receptacle must be at the same angle (the transition from horizontal to vertical), except with the joints having a horizontal surface.
After reviewing these rules, amounting to an action plan identifying the location of wiring and outlets, you can start. Do not forget about safety. Any construction work requires care and accuracy.
The selection tool ↑
There are plenty of ways shtrobleniya under the transaction. They are using different instruments: the wall chasers, rotary hammer, angle grinder, chisel and hammer, percussion drill. The first way is famous for an ideal result (smooth grooves) but has a high cost. The procedure of the punch is very fast and has a relatively low price. Chasing grinder gives a smooth groove, but konobeyevo creates a lot of garbage. The only plus chisel with a hammer in this case — deshevshe. But if you want the work was high quality — do not spare money on tools.
How to do furrow, take your pick. The work depends not only on the instrument but also from the master, so better to check once more the correct action, than to redo the work twice.
As stroebe wall for the wiring hole puncher ↑
Shtroblenie walls perforator is the most popular of all. The reason is that for making this construction procedure does not require a lot of time and money.
Before beginning it is necessary to conduct classical training walls. It is no different from what is done using other tools. All the steps are very simple, but take a responsible approach of the wizard:
- Check old wiring. Sometimes there are unpleasant moments when the walls are the wires from the old circuit of electricity. Don’t risk life and limb, carefully inspect the surface. There is a special device which quickly copes with this task.
- Directly marking the wall. Make sure that the wall is not left live wires, you can proceed to the schematic layout on the ground of the intended location of the transaction. Draw lines from the main distribution box to the current sources (switches, sockets, wires, lighting fixtures).
- Protection from dirt and dust. Don’t forget to hang Windows and doors: the process is not too clean, dust spread throughout the room, and it will be difficult to remove.
When ready, proceed to the main action. Take a drill and pre-cut line, drill a small hole at a distance from each other approximately 1.5 cm Then all depends on your instrument: either you switch it to the mode intended for shtrobleniya (need a special attachment) or put a simple drill. Carefully connect the holes by advancing a drill.

An angle grinder when chasing ↑
An angle grinder is another tool that will help to make the slots for the transaction. How to penetrate a concrete wall with it? Must-have diamond disk because the wall material is very durable. You can consult with a professional, and he maybe will prompt some other disk. But it is not necessary to complicate the task: diamond are easy to get, plus, with him the work will go much faster.
Thus, the process consists of several steps. First, cut two strips on the marked section of the wall. The slits should be parallel to each other and have a distance of 2 cm between them. Need a drill or other tool to release unwanted residues between cuts. You can take a punch with the so-called «hammer». After that, wiring is laid in the recesses and closed with a plaster.

Dust: is it possible? ↑
Two previous methods have one common disadvantage — the formation of large amounts of dust. Her coat is so large that the end to clean the room not even the industrial cleaner. People who are interested in purity in the home, prefer the chasers for making cuts. It is a tool that resembles a grinder, only it’s already built in diamond circles. The special casing allows you to adjust the distance between the two wheels and to control the depth of the furrows. The dignity of the chasers in the vacuum, not allowing the dust to exit outside the housing. The disadvantage is the cost of the tool. For one-time construction work, this method is clearly not appropriate to buy the tool will have a significant amount. But if you require the indispensable purity, you can rent a machine. Although not the fact that it will be inexpensive.
How much is the construction procedure ↑
The price process depends on the criteria of its implementation. It is clear that to do yourself at home profitable. The cost will directly depend on the tool, of plaster, of the posting. Sometimes it’s cheap, and sometimes not. For example, selecting a drill device, you need to pay only for the leads and Satelitni materials because the tool, as a rule, any man. But opting for the chasers, unlikely to save.
Having decided to order the wizard in a construction company or private specialist, you should not count on a reasonable price. Get ready to shell out a tidy sum. This work is dangerous, so the payment requested.
Home renovation is never complete without punching channels for electricity, so it is important to know the basic requirements shtroblenie walls, as well as to observe safety rules during the construction.
