Novel lattice type combined shear wall

Abstract

The invention discloses a novel lattice type combined shear wall. The novel lattice type combined shear wall comprises T-shaped flanges, truss web members and tie bars. Every two T-shaped flanges forma set and are oppositely arranged, and the T-shaped flanges are connected together through the truss web members. Every two tie bars form a set and are horizontally welded between the two corresponding opposite T-shaped flanges. The two tie bars in each set are symmetrically welded into cavities on two sides of the corresponding T-shaped flange, two ends of each tie bar are bent and welded on thecorresponding T-shaped flange, and the plurality of sets of T-shaped flanges are welded together to form a shear wall body of a multi-grid cavity structure. The shear wall has a brand-new shear wallstructure, does not need fire prevention measures, has good seismic performance, is low in steel content, greatly saves cost, is very convenient to construct, and can be prefabricated in a factory andpoured on site.

Description

technical field [0001] The invention relates to a novel shear wall, in particular to a novel lattice type combined shear wall, which belongs to the technical field of construction engineering. Background technique [0002] At present, prefabricated buildings are vigorously promoted in China. Traditional concrete shear walls are low in cost, but have poor seismic resistance, low ductility, and insufficient energy dissipation capacity; steel plate shear walls have good ductility, but cannot bear vertical loads, and can only bear horizontal loads. The single steel plate is in the center of the wall, and fire prevention measures are required, which increases the cost. Double steel plate shear wall, the steel tube bundle shear wall has good performance, can bear compressive bending shear load and has good seismic performance, but the steel content is high, the cost is high, and fire protection is also required, but the steel plates are on the outer edges of both sides of the wall...

Problems solved by technology

[0002] At present, prefabricated buildings are vigorously promoted in China. Traditional concrete shear walls are low in cost, but have poor seismic resistance, low ductility, and insufficient energy dissipation capacity; steel plate shear walls have good ductility, but cannot bear vertical loads, and can only bear horizontal loads. The single steel plate is in the center of the wall, and fire prevention measures are required, which increases the cost

Double steel plate shear wall, the steel tube bundle shear wall has good performance, can bear compressive bending shear load and has good seismic performance, but the steel content is high, the cost is high, and fire protection is also required, but the steel plates are on the outer edges of both sides of the wall. The fireproof structure will increase the thickness of the wall and occupy the space of the building
