Laminated slab bottom plate with concave-convex slab end and no rib exposure and mounting structure

The invention relates to the technical field of building industrialization, in particular to a laminated slab bottom plate with concave-convex slab ends and no rib exposure and a mounting bottom plate, the laminated slab bottom plate comprises a laminated slab bottom plate body, and a plurality of truss ribs which are arranged in parallel at intervals are arranged in the laminated slab bottom plate body; a plate bottom stress rib mesh formed by connecting a plurality of first bottom ribs and a plurality of second bottom ribs is further arranged in the laminated plate bottom plate body, and the length axis of the first bottom ribs is parallel to the length axis of the truss rib bottom ribs. A plurality of grooves and a plurality of bulges are arranged at the plate end of the laminated plate bottom plate body; and the end part of the groove bottom rib is exposed in the groove. The laminated slab bottom plate is reliable in stress performance and simple in structure, the technical problem that exposed bars at th
