Composite floor slab additional rigidity device and composite floor slab with same

The utility model provides a composite floor slab additional rigidity device and a composite floor slab with the same. The composite floor slab additional rigidity device comprises embedded parts, connecting devices and a connecting rod, the two ends of the connecting rod are each connected with one connecting device through bolts, and the lower end of each connecting device is provided with one embedded part; the embedded part comprises a bottom plate and embedded steel bars arranged at the bottom of the bottom plate, and the connecting device is connected with the bottom plate. The steel bar can replace a truss steel bar, provides additional rigidity for the composite floor slab in demolding and hoisting stages, meets the requirements of demolding and hoisting working conditions in the production and construction stages of the composite floor slab, meanwhile, considers the new and old concrete combination requirements of a composite surface, and reduces the steel content of the composite floor slab. 本实用新型提供
