[0002] As one of the important horizontal components in the building structure, the floor slab has the following main functions: (a) Under normal use, it needs to bear the dead load and live load of the floor slab's own weight, and transfer the load to load-bearing components such as beams and columns; (b) When the building is subjected to horizontal loads such as wind loads or earthquake loads, the floor slab's own in-plane stiffness is used to effectively transfer the horizontal load of the floor to the lateral force resistance system of the building structure.

[0003] The connection between floor slabs and wall panels is very common. At present, the wet concrete work on site for the connection between composite floor slabs and wall panels is heavy and labor costs are high. In addition, plastering is required at the connection between the wall panel and the floor slab, and vertical support formwork needs to be set up, which increases the difficulty of construction. In addition, the existing joints between floor slabs and wall panels use full-length structural steel bars, and because the full-length structural steel bars are placed above the surface layer of the floor slab and are far away from the bottom of the joint, the bottom of the joint is prone to cracking and water leakage.
