The prefabricated panel 31 serves to shield the upper port of the open cavity of the support member 1 and the lower port of the support member 1. The post-cast plate 32 is coated on the outer sides of the precast slabs 31 and the rib beam 2. The main ribs of the precast slabs 31 extend into the post-cast slab 32. The post-cast plate 32 and the rib beam 2 are integrally cast.

The utility model discloses a close rib cavity floor helps alleviateing the weight of floor through set up support piece in that the floor is inside in order to form the opening cavity, shields the last port and the lower port of opening cavity through the prefabricated plate, and the prefabricated plate can be makeed in advance through the mill in addition, has improved the efficiency of construction, has shortened the shaping time of floor, and then reduces the on-the-spot engineering time, has reduced engineering cost.

In the present embodiment, the support 1 comprises a plurality of side plates 11. The side plates 11 enclose to form an open cavity.

Specifically, the number of the side plates is four, the four side plates are arranged in a rectangular shape, and the four side plates are connected end to end.

In this embodiment, the side plate 11 is fixedly coupled to the prefabricated panel 31 by the coupling assembly 4. Specifically, the connection assembly 4 includes: the battens 41, the first tapping screws 42, and the second tapping screws 43 are connected.

The connecting battens 41 are provided to the inner wall of the side plate 11 in the circumferential direction of the opening of the open cavity.
