Fabricated concrete prefabricated slab

The utility model relates to the technical field of concrete prefabricated slabs, in particular to an assembly type concrete prefabricated slab which comprises a concrete layer, a steel bar truss is arranged in the concrete layer and comprises a plurality of stirrups and a plurality of steel tie bars, and each stirrup is perpendicular to the corresponding steel tie bar and bundled into two sets of parallel steel bar meshes through bundling wires. Bent rods are arranged at the two ends of the stirrup, lifting lug assemblies are arranged at the positions, close to the corners, in the concrete layer, first angle steel is symmetrically arranged at the two ends of the upper edge of the concrete layer, the length direction of the first angle steel is parallel to the length direction of the stirrup, and second angle steel perpendicular to the first angle steel is arranged at the two ends of the first angle steel. The length direction of the second angle steel is parallel to the length direction of the tie steel bars
