In layer concrete in 4 region, the portion that bends inwards is formed；The additional bar ring 2 and bend inwards portion while the fixation of both sides
Connection；The additional bar ring 2 across piece and with the portion's part superposition that bends inwards of bottom steel bar stress 1；Additional bar ring
2 and the portion of bending inwards of steel bar stress 1 be below truss bars, so as to ensure that both do not expose concrete surface.
Further, the additional bar ring 2 is using the structure type for closing reinforcing bar.
Further, the termination of bottom steel bar stress 1 uses the structure type with closing reinforced steel bar ring.
Further, the reinforced steel bar ring that additional bar ring 2 is formed with the bottom steel bar stress of piece both sides simultaneously across piece
Overlap joint, increase the anchoring property of edge joint position additional bar ring.
Further, the additional bar ring 2 and the portion of bending inwards are in rectangular configuration.
The beneficial effects of the utility model are：
1) bottom steel bar stress 1 does not stretch out the side of Prefabricated stacking floor 3, it is not necessary to special tooth mould, bottom reinforcement bars during production
Bar-mat reinforcement can be made directly integrally to be positioned in mould, great improving production efficiency；
2) during site operation, Prefabricated stacking floor is directly close to be stitched together, and sets post-cast strip without staying, is poured after reducing scene
With formwork and the work supported is set up, lifts site operation efficiency；
3) one closing reinforced steel bar ring of the top surface of Prefabricated stacking floor 3 formation is stretched out in the bending of bottom steel bar stress 1, meanwhile, close
Edge joint position additional rectangular closing reinforced steel bar ring is spelled, and is overlapped with the reinforced steel bar ring of both sides Prefabricated stacking floor, is formed after casting concrete
The concrete belts and engaged of three constraints, ensure that the good globality of piece both sides concrete and stress performance.
