Novel anti-seismic steel structure

Abstract

The invention discloses a novel anti-seismic steel structure, and relates to the technical field of steel structure anti-seismic innovation, the novel anti-seismic steel structure comprises a supporting steel column, the lower side of the supporting steel column is fixedly connected with a fixed base, the outer surface of the fixed base is fixedly connected with an anti-seismic mechanism, and the anti-seismic mechanism comprises an I-shaped plate mechanism and a vibration reduction ring mechanism; the I-shaped plate mechanism comprises a built-in damping strip mechanism, the built-in damping strip mechanism comprises an octagonal ring, the outer surface of the supporting steel column is movably connected with a locking mechanism, and the locking mechanism comprises a gear ring. A hexagonal movable block is moved up and down, so that an I-shaped plate mechanism does fan-shaped rotation around an upper end cap mechanism, a lower end cap mechanism drives a vibration reduction ring mechanism, a sliding block slides on a sliding rod, and therefore the height of an anti-seismic mechanism in the vertical direction is adjusted, and the problems that an existing anti-seismic structure is large in limitation and poor in anti-seismic performance are solved. And the effect of reasonably adjusting the form and the position of the novel anti-seismic structure according to the actual situation is achieved.

Description

technical field [0001] The invention relates to the technical field of anti-seismic innovation of steel structures, in particular to a novel anti-seismic steel structure. Background technique [0002] Seismic structure is the most critical issue that should be considered in seismic design. It plays a decisive role in safety and economy and is a comprehensive system decision. The seismic performance of a structure refers to the bearing capacity, deformation capacity, energy dissipation capacity, and Changes and developments in stiffness and failure patterns. There are following problems at prior art: [0003] 1. The existing anti-seismic steel structures are generally limited and can only be used in limited structures. After structural and functional changes, the anti-seismic structure cannot continue to be used. The limitations are too large and cannot be flexibly changed. Some anti-seismic structures can only Only the structure is stable and lacks the function of vibratio...

Problems solved by technology

[0005] The present invention provides a new type of anti-seismic steel structure, one of the purposes of which is to have the function of rationally adjusting the shape of the new type of anti-seismic structure according to the actual situation, and solve the problem that the existing anti-seismic structure has relatively large limitations and cannot be used flexibly after the structure and function change; Another purpose is to solve the problem of structural looseness caused by the shaking of the seismic steel structure during the earthquake, so as to achieve the effect of buffering the shaking, thereby reducing vibration and protecting its own structure; another purpose is to strengthen the connecting steel plate itself Respond to the strength and stability of the vibration, and solve the problem of loosening and deformation of the structure caused by the shaking of the steel during the earthquake; one of the purposes is to solve the problem of the locking of the structure during the adjustment process of the seismic structure, so as to achieve stable locking and earthquake resistance The effect of not deforming the structure
