The invention discloses a method for assembling a prefabricated concrete filled
steel tube core column stiffening
shear wall. According to the prefabricated
shear wall, concrete filled circular
steel tube core columns are vertically arranged and fixed in two
layers of reinforcing meshes at certain intervals, the two
layers of reinforcing meshes are fixed through tie bars, the concrete filled circular
steel tube core columns are fixed in a longitudinally and horizontally crossing type
rebar lattice, the reinforcing meshes are coated with concrete, the upper side and the lower side of each steel tube stretch out of the outer concrete by 150 mm -200 mm to facilitate the connection between an upper
shear wall sheet and a lower shear wall sheet in the later stage, and connecting bars are reserved on the left side of the wall and on the right side of the wall and stretch out of the outer concrete by 200 mm - 300 mm to facilitate the connection between a left shear wall sheet and a right shear wall sheet in the later stage. Compared with conventional
reinforced concrete shear walls, the concrete filled steel tube core column stiffening shear wall has the advantages of being higher in bending resistance, shearing resistance, hysteretic energy dissipation capacity and
seismic resistance. Meanwhile, the shear wall is prefabricated in a factory and assembled on site in a cup joint mode, the construction technology is simple, the overall quality of a building can be guaranteed, production efficiency is greatly improved, and labor intensity is relieved.
