Furthermore, prefabricated superimposed sheet is inside to be equipped with a plurality of hu zi reinforcing bars, and in a plurality of hu zi reinforcing bar both ends extended to the post-cast joint seam, can let prefabricated superimposed sheet link together with the cast-in-place concrete layer in the post-cast joint seam through the hu zi reinforcing bar.
Furthermore, a plurality of connecting reinforcement bars are laid on the top ends of the beard reinforcement bars, so that the beard reinforcement bars and the connecting reinforcement bars form a reinforcement bottom net, and the connection between the two prefabricated composite slabs is enhanced.
Furthermore, a plurality of anchoring reinforcing steel bars are jointly arranged inside the prefabricated composite slabs and the cast-in-place concrete layer, and the connection between the prefabricated composite slabs and the cast-in-place concrete layer can be enhanced through the anchoring reinforcing steel bars.
Furthermore, a plurality of transverse steel bars are connected between every two adjacent anchoring steel bars, and a longitudinal steel bar is connected between the transverse steel bars, so that the self strength of the cast-in-place concrete layer can be enhanced.
Furthermore, it is a plurality of prefabricated superimposed sheet and cast-in-place concrete layer are inside to be equipped with jointly to draw the reinforcing bar to one side for draw the reinforcing bar to one side and can extend the anchor in the cast-in-place concrete layer from prefabricated superimposed sheet bottom.
Furthermore, the cast-in-place concrete layer is filled in the T-shaped groove, the connection between the prefabricated composite slab and the cast-in-place concrete layer is further increased, and cracks are avoided.
The utility model has the advantages that:
the utility model discloses when using, through setting up prefabricated superimposed sheet, cast-in-place concrete layer has been pour on prefabricated superimposed sheet surface, forms the post-cast joint seam between two adjacent prefabricated superimposed sheets to the adjacent side bottom of prefabricated superimposed sheet is equipped with the reservation recess, and the inside polymer mortar that is equipped with of reservation recess pastes net cloth, thereby can strengthen connecting between the board, reduces the crack. Secondly, the adjacent side of the prefabricated composite slab is provided with a T-shaped groove, and the cast-in-place concrete layer can be riveted with the prefabricated composite slab by entering the interior of the T-shaped groove, so that the connection strength between the two prefabricated composite slabs is enhanced.
