Spliced composite slab structure

Abstract

The invention relates to the technical field of buildings, and discloses a spliced composite slab structure. The structure comprises a first composite slab and a second composite slab; the first composite slab comprises a first prefabricated slab, a first cast-in-place composite layer and a first welded steel bar frame; the second composite slab comprises a second prefabricated slab, a second cast-in-place composite layer and a second welded steel bar frame; a first stressed steel bar assembly and a first connecting steel bar net are arranged between the first composite slab and the second composite slab; the first prefabricated slab abuts against the second prefabricated slab; and the first cast-in-place composite layer and the second cast-in-place composite layer are integrated by pouring. According to the structure, the first welded steel bar frame and the second welded steel bar frame are of integral grid steel bar structures and play a role in welding fixing so that the thicknessof the first prefabricated slab and the second prefabricated slab can be reduced when being manufactured, the anti-shearing effect is evenly achieved, a large number of steel bars do not need to be bound on site, the workload on a construction site is greatly reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a spliced ​​laminated plate structure. Background technique [0002] At present, the most commonly used floor form of prefabricated concrete structures in the construction industry is the truss reinforced concrete laminated slab, which is fixed on the support with steel bars, and finally concrete is poured on the support and one or more spliced ​​laminated slabs to be poured. [0003] The main function of the truss reinforcement used in the existing laminated slab is to increase the rigidity and bearing capacity of the prefabricated floor during demoulding and hoisting of the prefabricated floor components (short-term working conditions). After the construction and installation of the prefabricated floor and the cast-in-place laminated concrete form a laminated slab (normal operating condition), a shear structure needs to be set at the interface between the prefabricated flo...

AI Technical Summary

Problems solved by technology

After the construction and installation of the prefabricated floor and the cast-in-place laminated concrete form a laminated slab (normal operating condition), a shear structure needs to be set at the interface between the prefabricated floor and the cast-in-place laminated layer of the laminated slab, while the existing The layout density of the truss reinforcement is not high, and the joint surface cannot be completely covered, and the structural force is unreasonable

And at the construction site, for the spliced ​​truss reinforcement laminated slabs, the connecting reinforcement between the slabs and the stress reinforcement of the cast-in-place laminated layer need to be manually bound to the truss reinforcement, which will cause a large workload on the construction site and reduce construction efficiency. high cost
