A prefabricated, non-removable floor slab
By setting column cavities and steel bar insertion structures at the ends of the floor slabs, combined with the cooperation of C-shaped inward grooves and ribs, the problem of insufficient rigidity in prefabricated floor slab connections is solved, achieving high-rigidity and stable floor slab connections, and improving the overall stability and construction efficiency of the building.

AI Technical Summary
When connecting existing prefabricated floor slabs, the rigid support at the beginning and end of adjacent slabs is insufficient, which leads to deformation or slight displacement, affecting the stability of the overall structure, especially under horizontal loads or vibration.
Column cavities and integrally cast steel bars are respectively set on the outer walls of the left and right ends of the floor slab body. Adjacent floor slabs form a large-span rigid support by inserting the steel bars and column cavities, and the connection strength is enhanced by sliding insertion through C-shaped inward grooves and ribs.
It improves the overall stiffness and deformation resistance of the floor slab, reduces local deformation and cracks under load, enhances the overall stability of the building, simplifies the construction process, and reduces the risk of construction errors and cracks.
