Description

[0002] At present, in infrastructure construction, splicing of fully prefabricated floor slabs is an important basic construction content. There are two main commonly used joint construction methods: one is the sealant filling method, which is characterized by no reinforcement in the joint area of ​​the prefabricated floor slab, which is directly filled with sealant. It has the characteristics of convenient and quick construction, but there is only an adjacent splicing and overlapping relationship between the two prefabricated floor slabs, and there is no mutual limiting relationship, which is prone to relative displacement of the prefabricated floor slabs, thereby causing the risk of joint failure; the second is the superimposed cast-in-place method, which is characterized by reinforcement in the joint area of ​​the prefabricated floor slab (commonly known as beard reinforcement), and a strip-shaped superimposed cast-in-place layer of about 60mm thick is reserved. The reinforcement on both sides is tied on site and then poured to form a spliced ​​whole, which is interconnected by horizontal steel bars to form a splicing seam with left and right traction, longitudinal limitation, and concrete filling limitation. The splicing reliability is significantly better than the sealant filling method, so it is currently more popular.
