[0026] First reinforcing bars 13 and second reinforcing bars 14 are respectively provided at both ends between the first rib 3 and the second rib 12 to increase the connection strength between the first rib 3 and the second rib 12, thereby enhancing the stiffness and bending and shear resistance of the precast floor slab structure.

The end of the diagonal bracing plate 16 near the first reinforcing rib 13 and the second reinforcing rib 14 is welded and fixed to the first reinforcing rib 13 and the second reinforcing rib 14 through the third welding part 17, and the end of the diagonal bracing plate 16 near the first rib 3 and the second rib 12 is welded and fixed to the first rib 3 and the second rib 12 through the fourth welding part 18.

[0028] The first reinforcing rib 13, the second reinforcing rib 14 and the first rib plate 3 and the second rib plate 12 are supported to improve the stability of the end connection of the first reinforcing rib 13 and the second reinforcing rib 14, making them less prone to deformation and breakage.

[0029] The first rib 3 and the second rib 12 are arranged in parallel, and a hollow part 4 is provided at the center of both the first rib 3 and the second rib 12.

The first rib 3 and the second rib 12 are distributed in parallel and are connected by the first reinforcing rib 13 and the second reinforcing rib 14, increasing the connection strength between the first rib 3 and the second rib 12, thereby enhancing the rigidity and bending and shear resistance of the precast floor slab structure. The first reinforcing rib 13 and the second reinforcing rib 14 are respectively provided with diagonal bracing plates 16 at both ends, which support the connection between the first reinforcing rib 13, the second reinforcing rib 14 and the first rib 3 and the second rib 12.
