[0002] Prefabricated buildings have the advantages of fast construction speed, short construction period, and large-scale labor savings, and have gradually become a trend in construction development.

[0003] The exterior walls of prefabricated buildings are mostly prefabricated components. To avoid affecting the structural safety, it is not allowed to re-drill holes in the exterior walls during construction. Therefore, it is difficult to set up scaffolding. Workers perform exterior wall operations without an operating platform, which is prone to safety accidents and causes personal and property losses.
