Description

Technical Field

[0001] The utility model belongs to the technical field of wire box threading damage prevention, in particular to a truss plate wire box threading damage prevention device. Background Art

[0002] In order to improve convenience and efficiency at the construction site, truss panels are used in public areas. After the concrete solidifies, the process of removing wooden formwork or aluminum film is eliminated. Wire boxes and wire pipes are installed on the trusses in advance. After the construction of the house is completed, the wires are directly arranged on the trusses in the ceiling, shortening the construction period.

[0003] Since the junction box is exposed on the surface of the truss plate, this construction method will cause the following technical problems to the junction box: (1) Before pre-installing the junction box, it is necessary to drill a hole in the truss plate. Some junction boxes are small in size, which makes the hole on the truss plate surface too small. If the hole on the truss plate surface is too small, it will be inconvenient to cut neatly. The edges of the cut openings on the truss plate surface surrounding the junction box are relatively sharp and retain burrs; (2) Since various racks need to be erected during house construction to facilitate the transportation of building materials, in order to be able to construct the ceiling, these racks are usually tall and need to be adjusted according to the construction requirements. (3) The above two phenomena make the edges of the cut openings of the truss plates around the junction box sharp, uneven, or even warped. During the threading process, the wires come into contact with and scrape against the edges of the cut openings of the truss plates around the junction box, causing damage to the outer skin of the wires and exposing the copper core, which can easily damage the wires and cause safety hazards such as leakage and short circuit, affecting the threading of the pre-buried junction boxes for electromechanical professionals.

[0004] Therefore, a device for preventing wire damage during wire threading of a truss plate box is designed to prevent damage to the wires. Summary of the Invention
