The utility model is provided with a steel bar groove, a reserved groove, a transverse additional steel bar and a longitudinal additional steel bar. When controlling the landing of the composite slab, the left end of the transverse additional steel bar is aligned with the reserved groove of the adjacent composite slab, so that the transverse additional steel bar is completely included in the reserved groove of the adjacent composite slab when the composite slab lands.

[0004] In the above-mentioned disclosed structure, a separately installed connecting rod is used and a reserved groove is provided, resulting in inconsistent heights. There is also a lack of a corresponding combination structure, which affects the stability of the combination positioning. In addition, the handle structure on the upper surface is prone to interference, affecting stacking placement, which needs to be improved. Utility Model Content
