Quickly-assembled concrete-filled steel tube laminated shear wall staircase and installation method

Abstract

The invention relates to a quickly-assembled concrete-filled steel tube laminated shear wall staircase and an installation method, and belongs to the technical field of house construction. The staircase comprises laminated shear walls, combined stairs, T-shaped cover plates and frame beams, wherein the combined stairs are sequentially connected between the two laminated shear walls on the opposite sides from bottom to top, one ends of the combined stairs are connected to floor plates through the frame beams, the other ends of the combined stairs are connected with the laminated shear walls through connecting pieces, and the T-shaped cover plates are arranged between the combined stairs. The staircase is constructed in advance at the speed of not less than one floor before the main body structure, vertical traffic is realized before house construction, the problem that staircase construction and floor construction are not synchronous at present is solved, the working efficiency is high, and meanwhile, the problems that the concrete staircase construction is slow and the pollution is serious are avoided.

Description

technical field [0001] The invention relates to a fast-installed steel tube concrete laminated shear wall stairwell and an installation method, belonging to the technical field of building construction. Background technique [0002] Existing stairwells include concrete stairwells and steel structure stairwells. Concrete stairwells include cast-in-place concrete stairwells and integral stairwells with prefabricated concrete stairs. Pouring into a whole, it has good integrity, high rigidity, firmness and durability, and strong shock resistance. According to the traditional process, there are many wet operations on site, and it is necessary to go through processes such as supporting formwork, binding steel bars, pouring concrete, curing, and removing formwork on the site. Due to external factors, the labor intensity of workers is high, and precision control is difficult. And it cannot be used before the formwork is removed, and the construction period is long, which affects th...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fast-installed concrete-filled steel pipe laminated shear wall stairwell, which solves the current problem of synchronous stairwell construction and floor construction, and realizes vertical traffic before building construction; avoids cast-in-place concrete stairs The problems of slow on-site construction and serious pollution; the prefabricated concrete stairs have heavy weight, high requirements for hoisting equipment, slow installation speed, grouting is required in the prefabricated staircase holes, and temporary support is required for construction, and the sound insulation effect of steel structure stairs Poor problems, while meeting the requirements of anti-corrosion and fire protection
