Construction method for assembly type annular reinforcement buckling concrete shear wall system

Abstract

The invention discloses a construction method for an assembly type annular reinforcement buckling concrete shear wall system. The construction method comprises the steps that prefabricated outer walls, prefabricated inner walls, prefabricated composite floor slabs, composite prefabricated air conditioner slabs and prefabricated stairs are transported to a construction site; prefabricated inner wall components of the first storey are lifted, corrected and fixed; the prefabricated air conditioner slabs, bay windows and molding bottom slabs of the first storey are lifted, corrected and fixed; prefabricated outer wall components of the first storey are lifted, corrected and fixed; prefabricated bay windows of the first storey are lifted, corrected and fixed; composite layer reinforcements of the first storey are bound; bottom beams and composite slabs of the first storey are subjected to cast-in-place concrete construction; cast-in-place columns and bay window components of the first storey are subjected to cast-in-place concrete construction; prefabricated component installation is conducted for outer molding of the first storey; the composite slabs of the upper layer are installed; and the steps above are conducted repeatedly till construction of the top storey is finished. By the adoption of the construction method, the construction quality can be guaranteed, and the assembly leakproofness is improved; and meanwhile, the construction time is shortened, and construction is accelerated.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for a prefabricated ring-bar fastening concrete shear wall system. Background technique [0002] There are many kinds of structural systems in the development of building construction. The prefabricated monolithic concrete shear wall structure system is widely used in high-rise buildings. However, it consumes more steel and funds, and is not suitable for small buildings. Existing small buildings are mostly block load-bearing structures, with slow construction speed, relatively long construction period, poor integrity, and poor heat preservation are the disadvantages of block load-bearing structures. At the same time, the error control of the existing prefabricated construction is difficult (mainly reflected in the control and adjustment of the plane deviation, elevation deviation and verticality deviation of the wall panel). The support performance and sta...

Problems solved by technology

However, it consumes more steel and funds, and is not suitable for small buildings.

Most of the existing small buildings are block load-bearing structures, the construction speed is slow, the relative construction period is long, the integrity is poor, and poor insulation is the disadvantage of block load-bearing structures

At the same time, the error control of the existing prefabricated construction is difficult (mainly reflected in the control and adjustment of the plane deviation, elevation deviation and verticality deviation of the wall panel). The support performance and stability performance are poor, which cannot meet the requirements for construction quality. , In addition, the correction method is too cumbersome and complicated, which affects the construction progress
