Shear wall construction process based on fully prefabricated floor slab

Abstract

The invention discloses a shear wall construction process based on a fully prefabricated floor slab. The shear wall construction process comprises the following steps: (1) binding shear wall steel bars at the bottom layer after the construction of a standard layer is finished; (2) respectively installing a shear wall inner template and a shear wall outer template on two sides of the shear wall steel bars; (3) pouring concrete; (4) installing a supporting system of the prefabricated floor slab; (5) hoisting the prefabricated floor slab close to one end of a shear wall to serve as a constructionplatform; (6) dismantling the shear wall inner template and the shear wall outer template to lift the shear wall inner template and the shear wall outer template to the construction platform; (7) hoisting prefabricated floor slabs which are not installed in the step (5); (8) binding shear wall steel bars, beam steel bars, column steel bars and floor steel bars on the upper layer; (9) respectivelyinstalling a shear wall inner template and a shear wall outer template on two sides of the shear wall steel bars; (10) pouring concrete; and (11) repeating the steps (4) to (10) to finish the shear wall construction layer by layer. The process can reduce the difficulty of cross-layer transportation of a shear wall template system and reduce the construction cost.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a shear wall construction process based on fully prefabricated floor slabs. Background technique [0002] At present, the construction technology of multi-storey houses in the field of building construction technology is roughly divided into two types, one is cast-in-place and the other is assembly. Among them, the cast-in-place building construction technology is that the beams, floors, and columns of the entire floor are poured at one time. The floor slab of the prefabricated building construction process generally adopts the form of a laminated slab, and then the steel bars are bound, the electricity is laid, and the concrete is poured as a whole, and then the construction of other concrete structures is carried out. [0003] The existing prefabricated construction technology of multi-story houses is to complete the construction of the first floor ...

AI Technical Summary

Problems solved by technology

[0003] The existing prefabricated construction technology of multi-story houses is to complete the construction of the first floor of the house, and then construct the upper house. The shear wall formwork system (including the shear wall inner formwork and the shear wall outer formwork) used in the construction process ) generally adopts wood plywood structure or aluminum formwork structure, but no matter which kind of shear wall formwork system is used, when the superstructure needs to be constructed after the construction of the first-floor house, the formwork needs to be disassembled, and the The shear wall formwork system is transported across floors to the upper floor. Since the upper floor has been hoisted at this time, the cross-layer transportation of the shear wall formwork system, especially the transportation and installation of the shear wall formwork, is cumbersome and requires a lot of manpower and material resources , resulting in higher construction costs
