Fabricated building laminated slab

The utility model discloses an assembly type building laminated slab which comprises a laminated slab body (1), a vertical inserting and positioning assembly, a pouring pipe (3) and a transverse inserting and positioning assembly. Every two vertically adjacent laminated slab bodies are movably connected in an inserted mode through one or more sets of vertical insertion positioning assemblies, every two transversely adjacent laminated slab bodies are movably connected in an inserted mode through one or more sets of transverse insertion positioning assemblies, and therefore the multiple laminated slab bodies are spliced to form a laminated slab face structure. A through hole and one or more pouring grooves (10) are formed in the laminated slab body, the pouring pipe penetrates through the laminated slab body through the through hole, and the one or more pouring grooves communicate with the pouring pipe and are connected with the one or more sets of vertical insertion positioning assemblies correspondingly, so t
