Embodiment Construction

[0022] Such as Figure 1-3 , the two sides of the laminated shear wall use square steel pipe 1 as the restraining member, weld two parallel steel plates on one side of the square steel pipe 1 as the guard plate 11, and the side of the square steel pipe 1 and the two guard plates 11 form a mounting groove A row of studs 4 is welded between the two guard plates 11 along the side of the square steel pipe 1, and the two ends of the laminated shear wall are inserted into the installation groove. The combined shear wall panel construction method shortens the length of the horizontal wall distributed steel bars protruding from the leaf plate (not less than 0.6 times the minimum anchorage length of the steel bars), and sets mechanical anchor joints at the ends to superimpose the two sides of the shear wall. There are transverse steel bars 5 stretching out at the ends, and there are mechanical anchor joints at the ends of the transverse steel bars 5. In this implementation, a small sec...

Abstract

The invention discloses a fabricated shear wall combining a concrete-filled steel tube and a double-sided composite wall. The fabricated shear wall comprises a composite shear wall body, wherein the end of the composite shear wall body extends into a mounting groove formed by one side face of a square steel tube stand column and two protective plates, a row of studs are arranged along the side face of the square steel tube, steel bars extending transversely are arranged at the ends of two hinge plates of the composite shear wall body, the square steel tube is filled with concrete, and the space between the two protective plates and the composite shear wall body is filled with concrete. According to the fabricated shear wall, a steel-concrete combined structure with the concrete-filled steel tube as the core is innovatively provided to serve as an edge component for restraining the shear wall, and the novel structure lateral force resistance system overcomes the technical defect that a traditional reinforced concrete shear wall edge component cannot be constructed in a fabricated mode.

Description

technical field [0001] The invention relates to a constraint structure of a superimposed shear wall. Background technique [0002] Assembling the overall laminated plate steel-concrete composite shear wall (hereinafter referred to as the present invention) originates from the technical system of laminated shear wall structure, which has a wide range of prefabricated buildings in the developed countries represented by Germany. Application, with a complete industrial chain of the whole process of standards, research and development, design, production, assembly and installation, maintenance and testing. After the laminated shear wall system was introduced to my country, after rapid development in recent years, a complete industrial chain has been formed, and it has been applied in prefabricated residential projects in Shanghai, Zhejiang and other regions across the country. [0003] Judging from the requirements of the industrialization development of new buildings in my coun...
