Furthermore, building glue is filled between the gaps of the convex plate and the slot.
Through adopting above-mentioned technical scheme, through filling building glue between the gap at flange and slot, strengthen the combination between the adjacent superimposed sheet body, in addition, do not produce the condition of leaking thick liquid when guaranteeing concreting.
Further, the building adhesive is polyurethane building adhesive.
By adopting the technical scheme, the polyurethane building glue is a sealant which takes polyurethane rubber and a polyurethane prepolymer as main components, has high mechanical strength, high adhesion, high tensile strength, excellent elasticity, wear resistance, oil resistance and cold resistance.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the supporting steel bars in the common laminated slab are replaced by the trusses and the supporting steel bars, so that the overall weight of the prefabricated laminated slab is greatly reduced, the prefabricated laminated slab is more convenient to transport, and in addition, the prefabricated laminated slab with lower dead weight greatly reduces the production cost and improves the production efficiency;
(2) through setting up flange and slot, prefabricated superimposed sheet when the installation, the flange of adjacent superimposed sheet body inserts in the slot, and the location is quick, combines more stably, through filling the building glue in the gap between flange and slot, improves cohesion, and the contact is inseparable, avoids producing the condition of leaking the thick liquid.
