In one embodiment of the present invention, the top portion 202 of the wall 200 is further formed with a cast-in-place portion 300, and the cast-in-place portion 300 may be integrally formed with the cast-in-place layer 104 of the composite floor slab 100. The first connecting rods 22 are inserted into the cast-in-place part 300 from one end of the sleeve 10 so that the second connecting rods 24 extend to the cast-in-place layer 104 of the laminated floor slab 100.
In the embodiment, a gap is formed between the prefabricated layer of the composite floor slab 100 and the top 202 of the wall body 200, and the cast-in-place part 300 is also filled in the gap. Thus, the connection strength between the composite floor slab 100 and the wall 200 is further enhanced. And on the other hand, the sealing performance of the joint of the laminated floor slab 100 and the wall body 200 is enhanced.
The embodiment of the utility model provides an in, all be provided with coincide floor 100 when the relative both sides of wall body 200, have the floor seam between the coincide floor 100 of the relative both sides of wall body 200, cast-in-place portion 300 is filled in this floor seam. In this way, the cast-in-place layer 104 and the cast-in-place part 300 of the composite floor slab 100 on both sides of the wall 200 can be formed by one-time casting.
In some embodiments, a plurality of connecting members may be provided, the plurality of connecting members being spaced along the floor slab. Wherein the second connecting rods 24 of some of the connecting members 20 extend into the cast-in-place layer 104 on one side of the wall body 200, and the second connecting rods 24 of other of the connecting members 20 extend into the cast-in-place layer 104 on the opposite side of the wall body 200. Thus, the connection between the composite floor slabs 100 on both sides of the wall 200 and the wall 200 is realized. Preferably, the second connecting rods 24 extending into the cast-in-place layer 104 on one side of the wall 200 and the second connecting rods 24 extending into the cast-in-place layer 104 on the other side of the wall 200 are alternately arranged along the floor slab joint in sequence.
Compared with the prior art, the utility model has the advantages of: the sleeve 10 can be embedded in the top 202 of the wall 200, the second connecting rod 24 is embedded in the cast-in-place layer 104 of the composite floor slab 100, and the composite floor slab 100 and the wall 200 are fixedly connected through the fixed connection of the sleeve 10 and the first connecting rod 22 of the connecting member 20. So, adopt this coupling assembling to realize the fixed connection of coincide floor 100 and wall body 200, avoided like prior art in need to the less cast-in-place downthehole concreting in space to the stability of being connected of coincide floor 100 and wall body 200 has been improved, and then has been promoted building quality.
