Quick-split type T-shaped steel concrete beam column connection node

Abstract

The invention relates to a quick-split type T-shaped steel concrete beam column connection node, comprising a section steel column, connecting plate assemblies, H-shaped steel beams and reinforcing ribs, wherein the two connecting plate assemblies sleeve the outer side of the section steel column in parallel; threaded holes are respectively formed in all the connecting plate assemblies; the plurality of reinforcing ribs are vertically arranged on each connecting plate assembly; the H-shaped steel beams are vertically fixed on the side face of the section steel column between the two connectingplate assemblies. Compared with the traditional universal node for section steel concrete beam columns, the quick-split type T-shaped steel concrete beam column connection node is produced in a way of connecting reinforcing steel bars with connecting plates and welding the connecting plates with the section steel column; by changing the lengths of studs, the requirement of misaligned connection of reinforcing steel bar joints is met, so that stress concentration is avoided. Furthermore, the percentage of the area of the reinforcing steel bar joints reaches 50%, so that superstrong connectionis realized. The quick-split type T-shaped steel concrete beam column connection node is higher in connection efficiency, and improves the node bearing capacity and ductility.

Description

technical field [0001] The invention belongs to the technical field of beam-column connection nodes, in particular to a quick-fit T-shaped steel-concrete beam-column connection node. Background technique [0002] Starting from the overall structure, the steel concrete structure has the dual advantages of steel structure and concrete structure. Compared with the reinforced concrete structure, because of its higher steel content and the same cross-section, the bearing capacity of the steel concrete member is larger than that of the reinforced concrete member; and it has good ductility and seismic performance; the T-shaped steel skeleton can be prefabricated in the factory, which speeds up the on-site construction speed. Compared with the steel structure, the outsourcing concrete of the steel concrete member improves the rigidity of the member, and the steel concrete member with the same steel content is compared with the steel structure member, and the steel concrete member i...

Problems solved by technology

However, the existing connection methods will bring many problems. For example, the installation of steel corbels will cause a sudden change in the cross-sectional bearing capacity and stiffness at the end, and concrete extrusion damage will easily occur. Decreased stability; the method of directly welding the longitudinal reinforcement to the connecting plate or the steel column will cause too many welding seams of the steel column, and the accumulation of welding residual stress will lead to the weakening of the section, thereby reducing the joint strength; steel bars of different strengths are welded to the steel , because of the different carbon content, the welding quality is affected, and the joint strength is also weakened
