Abstract

A steel beam and concrete wall semi-rigid full-bolted-connection joint comprises a reinforced concrete wall body (1), an H-shaped steel beam (2), web plate angle steel (5), upper and lower flange angle steel (6), a bolt (7) and a bolt (8). A tailored embedded part is arranged in the reinforced concrete wall body (1) and consists of reinforcement connectors (9), two steel plates (3), a plurality of straight anchor bars (4) and L-shaped anchor bars (12), the sizes of the two steel plates are identical, the steel plates are vertically placed on two sides of a reinforcement cage, the straight anchor bars (4) are welded between the two steel plates (3), at least eight circular holes (11) are drilled on one of the steel plates (3) and are arrayed to form two rows, each reinforcement connector (9) is arranged in the corresponding circular hole (11) by means of plug welding, the reinforcement connectors (9) are connected with the L-shaped anchor bars (12) between the two steel plates (3), and the H-shaped steel beam (3) is connected with the tailored embedded part by the web plate angle steel (5), the upper and lower flange angle steel (6), the bolt (7) and the bolt (8).

Description

technical field [0001] The invention relates to the field of steel-concrete mixed structures, in particular to a steel beam-concrete wall semi-rigid full bolt connection node. Background technique [0002] Steel-concrete hybrid structure system is an ideal anti-lateral force system, which combines the advantages of reinforced concrete structure and steel structure, and is widely used in high-rise buildings in my country, especially super high-rise building structures. The steel-concrete hybrid structure usually consists of a steel frame and a reinforced concrete core tube (or shear wall). The connection nodes are treated as ideal rigid joints or hinged joints. Rigid joints or hinged joints are commonly used connection forms in engineering design, and are reflected in the industry standard "Technical Regulations for Concrete Structures of High-rise Buildings" of the People's Republic of China and the local standard "Design Regulations for Steel-Concrete Hybrid Structures of ...
