Description

Technical Field

[0002] In construction projects, electrical boxes often appear inside shear walls, which can cause extrusion deformation during concrete pouring. The usual solution is to use wood to fill and support them. This method is difficult to provide both horizontal and vertical support at the same time.

[0003] Patent CN218346828U discloses a supporting structure for an electric box in a wall, including an electric box body, a cross-structured galvanized steel pipe, screws, nuts, angle steel, a limit structure, and an outer template. A screw is installed at each of the four ends of the cross-structured galvanized steel pipe. One end of the screw is inserted into the cross-structured galvanized steel pipe and fastened to the cross-structured galvanized steel pipe with a nut. The other end of the screw is welded to the angle steel. The outer surface of the angle steel is against the inner surface of the electric box body. The front side of the electric box body is covered with an outer template, and the electric box body and the outer template are fixed with tape. In actual use, the cross-structured galvanized steel pipe is not welded firmly, and it is easy to deform or the two galvanized steel pipes are separated from each other. Although the patent realizes longitudinal and transverse bidirectional support, the support area is small, and there is a lack of support for the back plate of the electric box. The support effect needs to be improved. Utility Model Content

The outer ends of the two galvanized steel pipes are respectively inserted with a first screw rod 4 and a second screw rod 7, and the first screw rod 4 and the second screw rod 7 are respectively screwed with a first limit nut 5 and a second limit nut 9, and the outer ends of the first screw rod 4 and the second screw rod 7 are respectively welded with a first angle steel 6 and a second angle steel 8 for supporting the side wall or the top wall of the electric box 1, and the upper and lower ends of the tube wall of the first galvanized steel pipe 2 on both sides of the second galvanized steel pipe 3 are respectively welded with a third angle steel 10 along the Y-axis direction, and the third angle steel 10 is used to support the back plate of the electric box 1, and the four third angle steels 10 are respectively welded to the outer wall of the second galvanized steel pipe 3 through connecting rods. By means of the alternating welding between the third angle steel, the second galvanized steel pipe and the first galvanized steel pipe, the new model has a firm skeleton structure, thus avoiding the problem of deformation or falling apart in actual use and improving the service life of turnover use.

[0021] In this embodiment, Figure 4 As shown, the four third angle steels 10 are respectively slidably connected with slide bars 12, the inner ends of the four slide bars 12 are connected with the back pressure plate 11, and the outer ends are welded with the force plate 13, the center of the force plate 13 is penetrated by the third screw 14, the third screw 14 penetrates the first galvanized steel pipe 2 and the second galvanized steel pipe 3, the front end of the first galvanized steel pipe 2 is welded with a sleeve 15 with internal threads, the third screw 14 is screwed with the sleeve 15, and a screw block is integrally formed at the outer end of the third screw 14.
