Straight type I-steel anti-seismic connecting joint

Abstract

The invention belongs to the technical field of steel structure joint connection and particularly relates to a straight type I-steel anti-seismic connecting joint. The straight type I-steel anti-seismic connecting joint comprises an I-steel I, an I-steel II, a flange connecting energy consuming plate, internal round holes, energy consuming ribs, lead pin holes, lead pins, a web connecting energy consuming plate, an I-type buffer energy consuming embedded unit, flanges and webs. The straight type I-steel anti-seismic connecting joint has the advantage of achieving certain initial rigidity and anti-seismic performance simultaneously; the I-steels can extrude the I-type buffer energy consuming embedded unit during relative displacement to consume energy and meanwhile to drive the flange connecting energy consuming plate and the web connecting energy consuming plate to consume energy, thereby achieving multiple energy consumption; a lead pin connecting manner can significantly improve thestructural energy consuming efficiency, meanwhile, the lead pins are convenient to replace and capable of adjusting damping as required and meanwhile transmitting internal force at the straight type I-steel anti-seismic connecting joint, thereby ensuring sufficient bearing capacity and appropriate rigidity of the straight type I-steel anti-seismic connecting joint and guaranteeing sufficient connecting stability as well as enhancing anti-seismic performance of the straight type I-steel anti-seismic connecting joint.

Description

technical field [0001] The invention belongs to the technical field of steel structure node connections, in particular to an I-shaped I-shaped steel seismic connection node. 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. There are ordinary bolted connections and high-strength bolted connections in bolted connections. Ordinary bolt connections were used the earliest, starting from about the middle of the 18th century. In the 1920s, rivets were used. In the second half of the 19th century, welded joints appeared again. Since the middle of this century, high-strength bolted connections have been developed, which can ensure that the nodes have sufficient bearing capacity and appropriate node stiffness to achieve the transfer of internal forces at the nodes, but the seismic performance of the connected node...

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
