Description

TECHNICAL FIELD

[0002] In the construction process of building engineering, a scaffold is connected with a building main body (a wall body or a beam component) through an embedded wall connecting piece, and the connection must have sufficient connection strength to ensure the safety of building construction. The existing embedded wall connecting piece and its construction method are as follows: while embedding the embedded wall connecting piece, a plug bolt for fixing the main body component formwork during the formwork stage must be installed at the same time; after pouring concrete, the formwork is removed, then the plug bolt is removed, and finally the scaffold fixing bolt is installed to fix the scaffold. However, in actual site construction, since the material of the plug bolt is engineering plastic and part of the plug bolt protrudes out of the formwork, the plug bolt is damaged and remains in the embedded wall connecting piece when the formwork is removed, so that the installation of the scaffold fixing bolt in the next process cannot be performed, at this time, destructive removal by manpower is required, the high-altitude removal operation not only has safety hazards and increases construction cost, but more importantly, if the destructive removal is improper, the reliability of the subsequent installation of the scaffold fixing bolt is directly affected, and safety hazards exist.
