Positioning protection device for electrical pre-buried PVC line pipe coming out of ground

Abstract

The invention discloses a positioning protection device for an electrical pre-buried PVC line pipe coming out of the ground, and the device comprises a horse stool, a pipe clamp, and a limiter. The pipe clamp is fixed on a plate low die through a positioning nail, and a horizontal support is disposed above a limiting hole of the limiter. Through the simple combination of the pipe clamp, the limiter, the horse stool and the horizontal support, the device can be suitable for the positioning protection of a cast-in-place slab and an on-beam bent-up line pope, and the position where the line pipeenters a wall can be flexibly adjusted through an adjustment nut on the limiter. The device is simple in structure, is convenient to manufacture, is simple and convenient in installation and disassembly, is high in installation precision of the line pipe, is stable and reliable in support, effectively solves the quality problems that the pipe arrangement at a part where a PVC pipe comes out of theground, a protection layer is not sufficient, the entering positions on the wall are staggered and a pipe mouth is blocked, fundamentally guarantees the hidden laying quality of an electrical pipe, guarantees that the construction precision meets the standard requirements, improves the work efficiency, saves manpower and auxiliary materials, reduces the engineering cost, can be repeatedly used, and is high in popularization value.

Description

technical field [0001] The invention relates to a technical field related to construction engineering, in particular to a ground positioning protection device for electrical pre-embedded PVC line pipes. Background technique [0002] The construction quality of the concealed laying of electrical conductor pipes in civil buildings is directly related to the progress, quality and construction cost of the electrical installation project in the later stage. If there is a deviation in the pre-embedded technology of electrical wire pipes during the civil construction, a large number of chiseling, chiseling and cutting will occur in the subsequent installation process. Additional work such as repairs will damage the building structure, form quality defects, and consume a lot of labor costs. The pre-embedding of electrical wires runs through the whole process of civil construction. At present, the pre-embedded wires in cast-in-place beams and slabs generally use flame-retardant insul...

AI Technical Summary

Problems solved by technology

[0003] 1. Multiple wire pipes are concentrated, arranged too densely, the wire pipe spacing does not meet the specification requirements, there is no concrete filling between the wire pipes, and there are too large gaps in the cast-in-place slab, which affects the structural bearing capacity

[0004] 2. The pre-embedded pipes have not been designed in depth and optimized, with more than two layers of crossover and overlapping, the pipes are not arranged strictly according to the design, the direction is random, and there are too many bending sections

[0005] 3. The line pipe is too close to the bottom mold of the cast-in-place slab or close to the bottom mold, and the thickness of the protective layer is insufficient, which may easily lead to damage to the line pipe and structural leakage

[0006] 4. The bending radius and bending position of the wire pipe are not accurate, and there is a deviation in the position where it enters the wall, which causes the wire pipe to be higher than the floor of the building or protrude out of the wall, and a lot of chiseling occurs during the secondary structure and electrical installation construction processing fee

[0007] 5. Rows of upper-bent wire tubes are not in a straight line, and they are misplaced front and rear. The position of entering the wall junction box is not accurate and tidy; the distance between the wire tubes and the wall is uneven, which will easily lead to rework when the wall is opened in the later stage.

[0008] 6. The nozzle of the upward bend is not sealed or the sealing is not tight, and mortar or debris enters the tube, resulting in chiseling and rework when the circuit is threaded.

The steel supports are all disposable, and the cost of materials consumed is very considerable, resulting in loss of benefits
