At present, the composite floor slab is most widely applied in an assembly type structure building, and has the advantages of template saving, high rigidity, good integrity and the like.

Generally, laminated floors can be classified into unidirectional slabs and bidirectional slabs according to their length to width ratios. When the unidirectional boards are installed, the unidirectional boards are usually connected in a 'close splicing' mode. The connection mode is simple in structure and convenient and fast to construct, and is the most common splicing mode for the one-way plates. However, it should be noted that, in this connection mode, the joints are only simply provided with short steel bars perpendicular to the slab joints, and the short steel bars cannot well transfer the temperature stress between the two side slabs, so that cracks often occur at the joints at the bottom of the composite floor slab.

The bidirectional plates have bearing function in two directions, and the joints between the plates are usually in a post-cast strip form, also called integral type splicing. From the practical use effect, the integral abutted seam has small probability of cracks between plates in the use process after the floor is delivered, the use effect is good, and the difficult problem of cracking between the unidirectional plates can be effectively avoided.
