Description

Technical Field

[0001] The invention relates to a steel structure beam-column combination for energy storage and gradient energy consumption, in particular to a steel structure beam-column combination for energy storage and gradient energy consumption and an assembly construction method thereof. Background Art

[0002] The combined structural system of prefabricated steel tube concrete columns and H-steel beams has the advantages of large span, flexible space division, light weight, good seismic performance, high integrity, and convenient construction. After forming a composite structure with the supporting shear wall core tube, it effectively promotes the rapid development of prefabricated steel structure buildings.

[0003] The standardization and industrialization of steel tube concrete columns, H-steel beams, nodes and other components meet the requirements of green building development.

[0004] The beam-column connection node is the force transmission center of the column and beam. Its construction measures and calculation methods are one of the main issues in the design of frame structures, and are also one of the key issues that directly affect the mechanical properties of frame structures. Therefore, the node form should be simple in structure, good in integrity, clear in force transmission, safe and reliable, save materials and be easy to construct.

[0005] Unreasonable design of beam-column joints will lead to "strong component weak point" situations, causing serious damage to the structure under earthquake loads, threatening people's lives and property safety.

[0006] At present, traditional connection nodes are mainly welded, supplemented by bolt connection. Since the quality of on-site welding is not easy to control, it is difficult to fully detect the brittle fracture parts, and the welding time is long, which limits the advantage of fast construction of prefabricated steel structures. On the other hand, the connection nodes in the prior art also have the phenomenon of unclear transmission paths, resulting in unnecessary waste. Summary of the invention

[0007] The present invention aims to solve the problem that the current traditional connection nodes are mainly welded and bolted. Since the quality of on-site welding is not easy to control, it is difficult to fully detect the brittle fracture parts, and the welding time is long, the advantage of the fast construction of prefabricated steel structures is limited. On the other hand, the connection nodes in the prior art also have the phenomenon of unclear transmission paths, resulting in unnecessary waste and quality problems.
