[0002] During the construction of high-rise buildings, it is necessary to embed electrical and mechanical boxes at set positions in the floor slabs. However, when the structure adopts aluminum formwork, it is difficult to fix the embedded electrical and mechanical boxes in the floor slabs. The traditional solution is to drill holes in the aluminum formwork in advance, and then nail the embedded electrical and mechanical boxes to the aluminum formwork with nails.

[0003] However, this method uses nails to nail the electromechanical and electrical boxes to be embedded in the set position of the aluminum template. First, it not only increases the difficulty of installing the electromechanical and electrical boxes to be embedded and the difficulty of removing the aluminum template, but also requires cutting off the exposed nails, which is labor-intensive and time-consuming, and increases the construction cost;

[0004] Secondly, nails are frequently driven into and taken out of the aluminum formwork. After repeated use, the electromechanical wire box is not firmly fixed on the aluminum formwork board, and it is easy to fall off, and the fixing effect is poor;

[0005] Finally, the structure has a poor sealing effect on the electromechanical box, and cement slurry can easily enter the electromechanical box, affecting the quality of the electromechanical box. Utility Model Content
