Prefabricated slab for assembling type hollow gridding plate floor structure

The invention relates to a prefabricated slab for an assembling type hollow gridding plate floor structure. A slab body (1) of the prefabricated slab is mainly made of concrete; a reinforcing bar or a steel wire is distributed in the slab body; and the prefabricated slab is characterized in that a fixing connecting device (3) is arranged at a corner (2) of the prefabricated slab. Thus, a structural bearing frame is assembled by using shearing prefabricated components; each of the shearing prefabricated components comprises a shearing bolt and lower rib limbs; the shearing bolt is vertically arranged; one ends of the lower rib limbs are integrally connected with the lower part of the shearing bolt; connecting reserving devices are arranged on the end parts at the other ends of the lower rib limbs; the shearing prefabricated components are connected by the connecting reserving devices, so as to form the structural bearing frame; the shearing bolt is taken as the center of each of the shearing prefabricated components and the lower rib limbs are distributed around the shearing bolt; the component bearing structure is reasonable; the shearing bolt can fully exert shearing resisting property; and the lower rib limbs can fully exert tensile resistance.
