Electrical pre-embedded wiring method for fabricated concrete structure building

Abstract

The invention discloses an electrical pre-embedded wiring method for a fabricated concrete structure building, and relates to the technical field of pre-embedded wiring of electrical pipelines in concrete buildings. The electrical pre-embedded wiring method for the fabricated concrete structure building comprises the steps of construction of a prefabricated plate, construction of a prefabricated wall, construction of a top plate cast-in-place layer and construction of a decoration cushion layer, wherein the line pipes which are all laid in the cast-in-place layer originally are arranged in thedecoration cushion layer in a scattered mode, and lighting loop line pipes are only reserved in the cast-in-place layer, so that the number of arranged line pipes in the cast-in-place layer is reduced. According to the method, the traditional definition of line pipe laying is broken through, strong and weak wire pipes are reasonably arranged, the problem that the wire pipes are difficult and disordered to lay in the cast-in-place layer is solved, and the engineering quality is improved; meanwhile, the weak current pipeline is moved into the decoration cushion layer, so that the weak current and the strong current are separately laid, and compared with a traditional method of laying the weak current and the strong current together, later refitting of owners is better facilitated, and the line interference is avoided.

Description

technical field [0001] The invention relates to the technical field of pre-embedded arrangement of electrical pipelines in concrete buildings, in particular to a method for pre-embedded electrical wiring in a prefabricated concrete structure building. Background technique [0002] In the construction process of prefabricated building structures, it is necessary to produce some components such as walls, roofs and stairs in the prefabricated component factory, and then transport the components to the construction site for assembly. Traditional component splitting usually divides the floor into two, the bottom floor is prefabricated, and the upper half of the floor is cast-in-place. At present, the pre-embedding method of strong and weak wires and pipes in the prefabricated concrete structure floor is basically laid in the cast-in-place layer. In this way, due to the large number of pipelines, the cast-in-place layer with only half the thickness of the roof cannot meet the cros...

Problems solved by technology

At present, the pre-embedding method of strong and weak wires and pipes in the prefabricated concrete structure floor is basically laid in the cast-in-place layer. In this way, due to the large number of pipelines, the cast-in-place layer with only half the thickness of the roof cannot meet the crossing position of the pipelines. , which brings great difficulties to the construction

In addition to the difficulty of construction at the intersection position, the entry cables of the general indoor strong electric box are all JDG32mm galvanized conduits. area

In addition, the strong and weak wires and tubes are all concentrated in the cast-in-place layer, which brings great quality hidden dangers to the construction quality of the cast-in-place layer; and the distance between strong and weak electricity is relatively close, and the interference of strong electricity on communication signals is also very serious
