Description

A new type of anti-seismic steel structure

technical field

The utility model relates to the technical field of steel structures, in particular to a novel anti-seismic steel structure.

Background technique

The steel structure is a structure composed of steel materials, which is one of the main types of building structures. The steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. With welding seam, bolt or rivet connection, the application field is very wide.

In the prior art, the utility model patent whose publication number is CN216475546U proposes a new type of anti-seismic steel structure, which mainly includes structures such as top beams, bottom beams, connecting blocks, and counterweights. When the above-mentioned patented technical solution is used in practice, the springs above and below the counterweight in a suspended balance state absorb the longitudinal vibration impact force, and then the counterweight produces reverse vibration damping on the top beam and the bottom beam, so it is helpful To reduce the vibration amplitude of the steel structure; the top slider and the bottom slider are driven to slide left and right through the counterweight, and the baffle is pushed to approach the connecting block, and the connecting rod hinged by the joint member is folded inward, thereby absorbing and suppressing the vertical vibration impact force .

However, the structure of the above-mentioned patented technical solution is too complicated, which not only makes the cost of the steel structure high, but also its anti-seismic principle is mainly realized through the movement of the top slider, the bottom slider and the baffle, and the indirect compression of the spring. During use, if the movement of the top slider, bottom slider or baffle is blocked due to external foreign matter entering the inside of the steel structure, such as sand and dust floating in the air, the seismic performance of the steel structure will be greatly weakened, that is, the above-mentioned The environmental adaptability of steel structure is poor. Based on this, we propose a new type of anti-seismic steel structure to well solve the above disadvantages.
