A kind of prefabricated steel strip concrete composite shear wall and its production and construction method

Abstract

The invention relates to the field of structural engineering, and discloses an assembly type steel strip and concrete combined shear wall and making and constructing methods thereof. The assembly type steel strip and concrete combined shear wall comprises a concrete shear wall and three layers of inner frames embedded in the concrete shear wall, and the inner frames comprise two distribution reinforcing meshes embedded in front surface layer and the back surface layer of the concrete shear wall and steel strips arranged on the interlayer of the concrete shear wall in a distributed mode; each steel strip comprises a steep strip body and a flange plate, each steel strip body is vertically arranged, the two ends of each steel strip body extend out of the concrete shear wall and are connected with the corresponding flange plate, and the plate surface of each flange plate is perpendicular to the extension direction of the corresponding steel strip; the adjacent flange plates at the end of the concrete shear wall are connected through high strength bolts, and filling treatment is conducted in horizontal joints. According to the assembly type steel strip and concrete combined shear wall and the making and constructing methods thereof, the wall is thin, the ductility is good, and shear wall connection is reliable and rapid.

Description

technical field [0001] The invention belongs to the field of structural engineering, and in particular relates to an assembled steel plate strip concrete composite shear wall and a manufacturing and construction method thereof. Background technique [0002] Prefabricated reinforced concrete shear wall is a good lateral force-resisting member with high rigidity, but its ductility and energy dissipation capacity are relatively poor, and the connection of prefabricated reinforced concrete shear wall is mostly connected by steel sleeve grouting, which is cumbersome to operate , the cost is high, and the ductility of reinforced concrete shear walls with vertical joints is good. The prominent features of steel plate concrete shear walls are high shear resistance and good ductility. Compared with ordinary reinforced concrete shear walls, these two kinds of shear walls have improved bearing capacity, ductility and seismic performance. The steel-concrete composite shear wall has th...
