Family fitment engineering circuit improvement single-tube single-wire system construction material and method

Abstract

The invention relates to a single-pipe single-wire construction material and a construction method for circuit transformation of a home decoration project. Its construction materials include: galvanized wire pipe and accessories - ∮10×1.0×3.8m galvanized wire pipe; ∮10 galvanized wire pipe straight head, screw joint; ∮10 galvanized wire pipe elbow; galvanized metal Junction box; PVC flame retardant wire tube and accessories; ∮10×1.0×2.5mPVC flame retardant wire tube; ∮10PVC flame retardant hose;∮10PVC flame retardant wire tube straight head and screw joint;∮10PVC flame retardant wire tube elbow ; Dedicated blue PVC flame retardant box and junction box, etc. Construction piping includes ground piping, wall surface and ceiling piping, socket line piping, etc., as well as piping and threading forms, line pipe fixing methods, wiring threading standards, wiring box installation standards, and wall and ground wiring groove standards. The invention effectively solves the difficult problem in the construction of electric wire pipelines in concrete walls.

Description

Technical field: [0001] The invention relates to the field of electrical pipeline installation in building decoration engineering, in particular to a single-pipe single-wire electrical pipeline connector and a construction method, and belongs to the technical field of international patent classification H02G "installation of cables or wires". Background technique: [0002] In the home decoration project, the indoor circuit needs to be modified. Under the current construction conditions, the hidden laying of the electrical circuit needs to be installed on the wall and the ground. Because the outer diameter of the protective galvanized iron pipe and the flame-retardant pipe used in the current specification Therefore, the groove depth of the wall must be more than 26mm to meet the requirements of buried construction after the pipeline is laid. However, when the groove depth of the reinforced concrete wall of the building exceeds 20mm, it will be limited by the reinforcement in ...

Problems solved by technology

[0002] In the home decoration project, the indoor circuit needs to be modified. Under the current construction conditions, the hidden laying of the electrical circuit needs to be installed on the wall and the ground. Because the outer diameter of the protective galvanized iron pipe and the flame-retardant pipe used in the current specification Therefore, the groove depth of the wall must be more than 26mm to meet the requirements of buried construction after the pipeline is laid. However, when the groove depth of the reinforced concrete wall of the building exceeds 20mm, it will be limited by the reinforcement in the wall. The steel bar must be stripped and bent to meet the installation requirements. Sometimes the steel bar will be cut off due to the worker's misoperation. Both of these situations will cause serious hidden dangers to the load-bearing and structural safety of the wall.

In addition, if the wires are directly buried without passing through the pipe, it is not allowed for building electrical safety and fire safety
