Description

Technical Field

[0001] The present invention belongs to the technical field of construction protection of electrical pre-buried wire pipes in construction engineering, and in particular provides a nested protection method for electrical pre-buried wire pipes, which effectively ensures the pre-buried quality of the pre-buried wire pipes and ensures that the wire pipes are not blocked by concrete during the pouring process. Background Art

[0002] The electrical system is an indispensable sub-project in construction projects, and the laying of cables is often done by concealed installation and threading, which makes it necessary to pre-buried wire conduits during civil construction. The lines at the distribution box are mostly arranged in rows. If certain fixing and protection measures are not taken during the construction process, it is difficult to ensure the accuracy of the pre-buried position of the wire conduit. It is also very likely that the wire conduit will be blocked during the concrete pouring process, which will have a great impact on the later unblocking and threading. Summary of the invention

[0003] The purpose of the present invention is to provide a nested protection method for electrical pre-buried wire tubes, which solves the problems of inaccurate pre-buried positions and blocked wire tubes. The uniformity of the arrangement size of the reserved wire tubes is ensured, which is neat and beautiful; the upper opening is closed to avoid blocking the wire tubes during concrete pouring; the upper opening of the reserved tube is flush to avoid secondary cutting of the tube when installing the box; and the spacing size between each wire tube is made according to the piping size of the distribution box, which ensures the accuracy of the size during installation.

[0004] The construction steps of the present invention are as follows:

[0005] (1) Making a nested protective device: bend a round steel bar into a handle 1 shape, weld it to the middle part of a fixing bar 2, weld a nested tube 3 at the bottom of the fixing bar 2, and form a self-made nested protective device, and use this device to fix and protect the electrical pre-buried wire tube;

[0006] (2) Install the steel bars at the bottom of the floor slab;

[0007] (3) Conceal the electrical conduit 4 and turn it up to the corresponding height;

[0008] (4) The electrical conduit 4 is fixed with a nested protective device, and the electrical conduit 4 is inserted into the nested tube 3 in sequence and fixed firmly;

[0009] (5) Install the upper layer of floor slab reinforcement;

[0010] (6) Pouring floor slab concrete;

[0011] (7) After the pouring of floor slab concrete is completed, the nested protective device is removed and subsequent operations are carried out.

[0012] The present invention mainly makes a nested protective device, and uses the device to fix and protect the electrical pre-buried wire pipe. The nested protective device consists of a handle 1, a fixing bar 2, and a nested tube 3. The handle 1 is made of φ6 round steel, the fixing bar 2 is made of 40*4 galvanized flat steel, and the nested tube 3 is made of JDG tube. The handle 1 is 150mm long and 80mm high, which is suitable for human hand insertion. The handle 1 is welded to the middle part of the fixing bar 2. The length of the fixing bar 2 is determined according to the total length of the pre-buried wire pipes in a row. The nested tube 3 is 50mm long and φ25 in diameter, and is welded and fixed on the fixing bar 2. The spacing between the nested tubes is determined according to the spacing of the wire holes of the distribution box. The protection method is: after the floor steel bars are installed, the electrical wire pipe 4 is constructed, the nested protective device is nested on the pre-buried electrical wire pipes in a row, and the electrical wire pipes 4 are inserted into the nested tubes 3 in sequence and fixed firmly. In this way, the spacing size of the wire pipes in a row is the size between the wire holes of the distribution box, which ensures the accuracy of the size of the wire pipes and the distribution box when they are installed. This device is installed on the upper part of the embedded pipe to prevent concrete from entering the pipe and blocking the wire pipe during pouring. At the same time, the nested protective device can be reused, saving costs and facilitating construction.

[0013] The beneficial effects of the present invention are:

[0014] 1. Advancedness: The nested protective device is simple to make and easy to use, and the protective method is simple to operate.

[0015] 2. Necessity: To ensure the parallel dimensions of the pre-buried electrical conduits, prevent concrete from clogging the conduits, reduce the workload of unclogging, and make the conduit heads neat and flat to improve the visual quality of the project.

[0016] 3. Cost saving: The use of this method reduces the workload of manual pipe cutting and blockage removal in the later stage, improves efficiency, and the nested protective device can be reused, saving costs. BRIEF DESCRIPTION OF THE DRAWINGS
