Assembly construction method for PVC wire pipe hidden lying

Abstract

The invention discloses an assembly construction method for PVC wire pipe hidden lying, which comprises the following steps that: (1) standard bellows and direct heads are pre-manufactured in batch in advance; (2) according to markers for a shop drawing, the positions of a switch, a socket and a lamp cap box are marked on a template, and the directions of conduits are marked by arrows; (3) one end of each elbow extends out of a floor, a conduit plug is used for sealing the pipe end of the end, and a clamp is used for fixing and positioning the elbow; a point positioning joint is fixed on a positioning point at a temperature marking position, and the direct head is sleeved on the point positioning joint and positioned; the lamp cap box is installed; the lamp cap box is arranged at a lamp cap box marking position and fixed; and (4) piping: a PVC wire pipe and the direct head are respectively connected with the elbows at all positioning parts, the lamp cap box and the direct head at the positioning point. The assembly construction method for PVC wire pipe hidden lying has the advantages of good quality, high efficiency, material saving, environment protection, simple procedures, convenient operation and the like.

Description

technical field [0001] The invention belongs to a wire pipe construction method, in particular to an assembled construction method for concealed laying of a PVC wire conduit. Background technique [0002] The laying of wire conduits is an indispensable item in various building constructions. At present, the concealed laying of PVC wire conduits in cast-in-place slabs has been stuck in the traditional process of bending on site, tape binding and positioning, tape sealing of pipe openings, direct head bonding with glue, and beam-through pipes opening holes on the formwork. , the method is as follows: [0003] 1. Laying out: mark the line pipes of the incoming switch, socket and beam plate on the template respectively; [0004] 2. Drilling: Open the holes for the beams and boards, and clean the sawdust; [0005] 3. Pipe laying: After the steel bars are installed, align the bent elbows on the site with the marking line and fix them on the steel bars with tie wires, then combi...

AI Technical Summary

Problems solved by technology

[0006] There are many disadvantages in the existing laying methods of wire conduits: one is on-site bending, since the rebound of PVC wire conduit materials is greatly affected by factors such as temperature and time, the angle and radian cannot be guaranteed, and the displacement of the elbow on the wall is serious, making it difficult to It is perpendicular to the ground, and the phenomenon of duckbill-shaped flat pipes often occurs after the correction, and the pipe head is too much above the ground, which wastes materials; the second is tape binding, which can only be tied together to fix the elbows protruding from the floor, and cannot be adjusted. The center distance of the pipe matches the center distance of the junction box line pipe entrance, which cannot protect the damage of the pipe head protruding from the floor by external force (such as the fall of the formwork, frame pipe and fasteners during the demoulding); the third is that the tape sealing and removal are troublesome , the tape cannot be reused, easy to wear, and has poor reliability; fourth, the formwork drilling construction is troublesome and destructive to the formwork, which reduces the turnover rate of the formwork, and the concrete is prone to leakage during pouring, which affects the quality; fifth, the wall masonry It is time-consuming and labor-intensive to clean and pre-embed
