A shock-absorbing steel structure node member

Abstract

The invention discloses a damping type steel structure joint component. The damping type steel structure joint component comprises a buffer frame and a damping steel frame, a supporting steel frame isdetachably arranged inside the buffer frame in a sleeved mode, a fixing base is arranged on the inner side of the buffer frame, a buffer push rod is rotationally arranged on the fixing base, a springpull tab is arranged at the end of the buffer push rod, and the spring pull tab penetrates through the supporting steel frame; the damping steel frame is vertically arranged on the outer side of thesupporting steel frame, and a limiting groove is formed in the supporting steel frame; after a worker hears the alarm sound, the worker immediately makes corresponding work, and the situation that thesteel structure is pressed for a long time and fractures to cause greater danger is avoided. Compared with the prior art, the damping type steel structure joint component is provided with a pluralityof buffer rods and buffer steel plates for combined damping, the longitudinal damping effect is improved, and meanwhile the transverse damping effect of the damping steel frame is improved through the buffer frame in the transverse direction; when the buffer steel plates are impacted, the buffering steel plates move downwards, and at the moment, a second spring plays a role in buffering the buffering steel plates, so that the buffer steel plates are decelerated and the contact time with the damping steel frame is delayed.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a shock-absorbing steel structure node member. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and antirust processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, stadiums, super high-rises and other fields. [0003] Most of the current factory buildings use steel structures; most of them do not have shock absorbing mechanisms at the nodes, so when a large external force is applied, the compressive load at the nod...

AI Technical Summary

Problems solved by technology

[0003] Most of the current factory buildings use steel structures; most of them do not have shock absorbing mechanisms at the nodes, so when a large external force is applied, the compressive load at the nodes increases, and the bolts are easy to break at the nodes, resulting in trusses and steel columns. Disconnection greatly affects the stability of the steel structure. In addition, when the steel structure is subjected to a strong impact force, it is usually impossible for workers to observe it when using it, and there is a certain danger. Therefore, we provide a shock-absorbing steel structure node member , to solve the problems raised in the above background technology
