Anti-rotation strengthening support connection H-shaped steel vertical joint

Abstract

The invention discloses an anti-rotation strengthening support connection H-shaped steel vertical joint, and belongs to the technical field of steel joint connection. The vertical joint comprises a right-angle energy consumption connecting steel plate, an energy consumption rib, an inner circular hole, a branch energy consumption connecting steel plate, vertical H-shaped steel, horizontal H-shapedsteel, a lead pin hole, a lead pin, a flange, a web plate, a joint anti-rotation strengthening connection damping device, a first right-angle energy consumption steel plate, a second right-angle energy consumption steel plate and an anti-rotation support energy consumption steel plate. The vertical joint has the advantages that the joint has initial rigidity and anti-seismic property and improvesthe problems of easy embrittlement and poor anti-seismic property and energy consumption capability of welding of vertical joints of traditional H-shaped steel, the energy consumption efficiency of the joint is remarkably improved, and the joint has multi-direction energy consumption effects.

Description

technical field [0001] The invention belongs to the technical field of steel structure node connections, in particular to an H-shaped steel vertical node connected by anti-rotation reinforcement supports. Background technique [0002] Steel structure connection generally refers to the interconnection between steel structure members or components. Steel structure connections are usually welded, bolted or rivet connected, and bolted connections include ordinary bolted connections and high-strength bolted connections. Ordinary bolt connections were used the earliest, starting from the middle of the 18th century; rivet connections began to be used in the 1820s; welded connections appeared in the second half of the 19th century; high-strength bolt connections have been developed since the middle of this century, which can ensure The nodes have sufficient load-bearing capacity and appropriate node stiffness to transmit internal forces at the nodes, but the seismic performance of ...

AI Technical Summary

Problems solved by technology

The material of the steel structure connection joints currently developed is easy to become brittle, resulting in residual stress, residual deformation, and welding defects, which have an adverse effect on the fatigue and stability of the steel structure. It depends more on the skill level of the welder, and the inspection workload is high when the quality inspection requirements are high. Larger and poor seismic performance, so the energy-dissipating manufacturing process and energy-dissipating capacity of some steel structure connection nodes still need to be further improved
