Shtroblenie walls for electrical wiring
Installation of electrical wiring in a hidden way allows you to hide communications under a layer of decoration and not clutter up the interior with unattractive details. But for laying wires, you need to prepare channels. Slitting walls for wiring in Tallinn at AVGroup is the performance of work of any volume and complexity at a high-quality level.
Features of chasing for electrical wiring
Grooves - small grooves on the surface of structures, in which cables are laid during installation. Channels can have different depths:
- for single wires - 15-20 mm;
- for groups - up to 30 mm.
Slitting causes weakening of structures, therefore it is forbidden to work in load-bearing walls or floor slabs. In panel buildings, gating can only be done in the vertical direction., avoiding cutting of the working reinforcement.
The depth of the channel in reinforced concrete should be less than the thickness of the protective layer by 2-3 mm. It is undesirable to expose the reinforcement. Deprived of protection, metal corrodes quickly, due to which the load-bearing capacity of the panel falls. this is dangerous, since damage to the reinforcement cage can lead to deformation of the walls and collapse.
Grooves for electrical wiring, according to the state law on electrical safety, are allowed to be cut only along straight lines. Laying with a slope is not allowed, as well as the intersection of channels at any angle, except direct.
Unlike electrics, chasing under pipes is carried out with a slope to ensure water flow into the main in case of repair of individual parts of the pipeline. Slope angle for the normal functioning of the water supply, sewerage or heating is set by the project documentation.
Strobe for wiring: stages of manufacturing
Before starting work, the surface of the walls is cleaned of old finishes. It is recommended to cover openings with foil or cloth.. The walls are marked according to the project of electrical work. Places are marked, where the sockets will be installed, switches, fixtures. Then vertical lines are drawn up from these points., which are connected horizontally to the junction box.
When designing wiring, it is necessary to ensure the safety of building structures and safety when using networks. For this, restrictions on the location of the cables are introduced.:
- 150-400 mm - from ceiling to floor surface;
- not less 400 mm - from gas lines, heating batteries;
- no closer 100 mm - from corners, openings, columns, niche;
- no more 3 m - from the junction box to each of the points.
Grooves for electrical wiring are drawn in two parallel lines, and for sockets and other equipment - in the form of circles of the corresponding diameter.
Furrows are cut along the marking contour with a grinder or a wall chaser. The inner part is removed to the desired depth. For counters, junction boxes, for switches and socket-outlets, holes are drilled using a round-bit perforator with victorious solders.
The chipping job is physically hard and very dusty.. It is not easy to do it yourself.. Plus, professionals use specialized tools. Handling them takes skill, but getting the result is much faster, and dustiness is reduced to a minimum thanks to powerful vacuum cleaners.
How much is a meter for wiring
The pricing policy of our company is very loyal to the customer. We are not chasing super profits, but honestly we do our job.
The price of chasing depends on the material of the walls., channel lengths and depths, number and size of nests. We work with bricks, monolithic reinforced concrete, concrete blocks, gypsum.
Complex volumetric projects require careful calculation. The final estimated cost of work for the provision of services is determined by a specialist.
The approximate price of a groove per meter is indicated on the website. She does not take into account all the nuances, therefore, you can learn more about the prices for wall chasing for wiring from our managers.
