How to wall the walls with your own hands: we safely hide the wiring in the walls

The wiring device, including the slashing of walls for wiring, refers to the responsible types of construction and repair work. They are regulated by a number of rules and regulations. Basic: SNiP 31-02 , POE ( Rules for the installation of electrical installations) and profile GOST s. A detailed study of these documents indicates a rather strict regulation of electrical wiring rules in buildings of any type.

The most technological and safe is considered to be wiring, covered with plasterboard, suspended ceilings, etc. In the capital constructions, concealed wiring passes in special channels obtained by shunting in vertical, horizontal or inclined directions.

This stowing for wiring is regulated as follows.

• It is forbidden to shred in any direction, except for horizontal or vertical( attic - an exception).
• Strictly forbidden in interstorey floors.
• Horizontal wall slashing under the wiring is made no closer than 15 cm from the floor.
• Stroke passing near the doorways, corners, can not be closer than 10 cm.
• The gas pipeline and the string can not be closer than 40 cm.
• The shroud itself can not be deeper and wider, 2.5 cm.
• ContinuityShtroby limited to three meters.
• In addition, stowing under wiring in multi-storey panel houses is possible only in partitions that do not perform carrier functions. On bearing walls it is recommended to use slightly convex decorative columns, inside of which electrical communications are laid. They revitalize the interior, avoiding labor-intensive work.

Violation of these requirements can result in serious material losses even in the distant future. As a result of an accident that occurred at any time after the sale of the premises, the owner is responsible for the consequences, which made changes to the standard wiring.

Preparatory works for

The prospective routes for stoking the walls under the wiring and the locations of the points for installing the electric fittings are transferred to the plan, taking into account the proximity of the door, window openings, niches and ledges, communications. On its basis, the calculation of the number of required materials, as well as the complexity of the proposed work.

The plan is also necessary in order to have in the future a real picture of the power network device in a particular room.

Then the plan in the form of a markup is transferred to the previously inspected wall or enclosing structures. After that you can start work.

Routing or stowing for wiring is performed in the following ways.

1. Hand tool( chisel).
2. Hammer or impact drill.
3. Angle grinder( grinder) with subsequent selection of material by chisel or perforator.
4. Special tool - shtroborezom.

In premises with an arranged interior, the use of power tools requires maximum localization of the work site, since the formation of fine dust in extremely large volumes is inevitable. Decide how to properly wall the walls for wiring, it is necessary with this main factor in mind.

Tools for video gouging

Manual wall shredding

For small volume or repair in residential areas, the manual laying of strobes is most justified. On the brick, foam concrete or soft stone, parallel grooves are first punched, after which the necessary depth is selected.

This requires hammer and chisel .The formation of dust with this method does not practically occur. In the market there are hand chisels with a hard-alloy tip. The use of such a tool will speed up the work.

The concrete base makes this method impossible due to extremely high time costs.

Shredding with a perforator or a drill with vibration

This method requires elementary skills in working with power tools. Dust is formed in small quantities. Specially for such works, various kinds of chisels are produced: point, flat, and spatula.

When slotting together with a perforator, a channel chisel is also used.

The use of these attachments greatly speeds up work, including on concrete walls. At purchase it is necessary to specify, whether the nozzle in honing needs. Some of the chisels are reinforced by the shot blasting method, and self-sharpening will break the protective coating.

First, the boundary channels are worked through, then the strobes are sampled, and only along the channel.

Angle grinder - Bulgarian

A diamond-coated disc is used for shtrobleniya. Sampling is carried out by a puncher or drill. The channel will be smooth, but inevitably the formation of a large amount of dust.

Canalize it can be industrial( ideal) or household vacuum cleaner. The assistant holds a fence nozzle near the bulgarian, observing a safe distance.

Shtroblenie walls using shtroboreza

This is a professional tool that most fully demonstrates how to properly wall the walls, but its cost is quite high. The principle of the Bulgarian is used, but with two cutting discs. A special cover closes the place of slaughtering, on it there is a branch pipe for fixing the hose of the vacuum cleaner.

The width and depth of cuts are set before starting work. Sampling is carried out in a similar manner to the previous methods. Dust does not enter the room, the stellite is even, the outer chips of the base are excluded.

Preparing shtroby for laying the cable

After getting the right size shtroby it must be carefully cleaned from dust. Then the channel must be primed. The primer will bind the remaining dust and ensure good adhesion of the surface when finishing the walls. Not only the wall, but also the wall, is ground not only 5 cm on both sides.

Cable laying in the

Before walling the wall for wiring, you need to determine the size of the channels. Cables in strobu are laid exclusively in special sleeves( corrugations).This increases the fire safety of the wiring itself through natural ventilation and makes it possible to replace the cable without disturbing the wall covering. Sleeves can be plastic or metal.

In residential areas, smooth or corrugated pipes made of polyethylene or vinyl are used.

Corrugated sleeves allow to do without fittings, angular or connecting. The ribbed surface provides additional rigidity under mechanical loads. Different diameters of the sleeve are available, which makes it possible to facilitate the strobing of the walls under the wiring due to a reasonable reduction in the size of the shtroba.

After tightening the cable in the sleeve, it is fixed in the groove with gypsum mortar or a plaster mixture that can quickly grasp. Fastening it is done in small sections in 1 meter. The turning points must be fixed on both sides at a distance of 3-5 cm

Conclusion

Even before the walls are wired for wiring, it is worth familiarizing with the numerous video materials, have the necessary tools, cables, pipes, consumables. The seats for the electric fittings must be ready.

It should be noted that modern tools and materials allow you to make shtroby own hands. Quickly and efficiently. A great deal of time may be required only by preparatory work.
