Description
Technical Field
The invention relates to the technical field of buildings; in particular to a threading method of an electric concealed pipe of a wall body.
Background
The electric concealed pipe is a pipeline buried in the wall, and is used for reserving a passage for an electric circuit to pass through in the wall so as to facilitate the passing of an electric wire during subsequent electric wiring.
Since the main trunk is formed by connecting multiple sections of wires, the wires are usually led through the concealed conduit and the head of the wires is pulled out to a required length. In the above-described step of pulling out the head of the electric wire to a desired length, the electric wire is pulled out by a manual force. This has the following problems, 1 is labor-wasting and workload-heavy; 2, the wire pulling efficiency is low, and the time is wasted; 3 the mode of manpower can make the electric wire of pull-out end irregularly buckle for the electric wire later stage is used the trouble and is increased.
Therefore, how to provide a wall electric concealed pipe threading method which is more convenient to operate, more labor-saving and more stable for a retainer body becomes a technical problem to be solved by technical personnel in the field.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a more convenient operation, can be more laborsaving, the electric concealed pipe threading method of wall body of the stability of retainer body that can be better.
In order to solve the technical problems, the invention adopts the following technical scheme:
a threading method for an electric hidden pipe of a wall body is characterized in that two ends of a strip-shaped frame body are overlapped between a wall surface where the opening of the electric hidden pipe is located and the ground, the opening of the electric hidden pipe is located below the inner side of the frame body, a wire end of an electric wire in the electric hidden pipe is pulled out and bypasses at least one pulley located on the frame body downwards, then the wire end is connected and fixed to a winding mechanism on the frame body, a handle of the winding mechanism is shaken to realize wire pulling, and meanwhile, the stability of the frame body is kept by means of stress of the pulley.
