The integrity of the superimposed floor slab is good, and the upper and lower surfaces of the slab are flat, which is convenient for the decoration of the veneer layer, and is suitable for high-rise buildings and large-bay buildings that require high overall rigidity. The prestressed main reinforcement of the thin slab is the main reinforcement of the superimposed floor slab, and the upper cast-in-place concrete layer is only equipped with negative moment reinforcement and structural reinforcement. The prestressed sheet is used as the bottom form for the cast-in-place concrete layer, and it is not necessary to support the formwork for the cast-in-place layer. The bottom surface of the thin plate is smooth and flat, and the ceiling can no longer be plastered after the seam of the plate is treated. This kind of superimposed floor has the advantages of the integrity of the cast-in-place floor, high rigidity, good crack resistance, no increase in the consumption of steel bars, and saving of formwork. Laminated boards have been widely used in the construction process, and the construction period has been greatly shortened due to its convenient installation. There are many types of laminated board in the technology used on the site, and the splicing technology between the laminated boards is usually in the form of , the reinforcing bars protruding from one side of the laminated board are inserted into the reinforcing steel jacks on one side of the other laminated board to form a reinforcing bar connection method. But no matter what kind of structure, it is easy to leak grout at the splicing when it is superimposed with the cast-in-place concrete after splicing.
