Self-resetting swing shock-isolation system

Abstract

The invention relates to a self-resetting swing shock-isolation system, comprising a spring reset mechanism and a crab-shaped swinging mechanism, wherein the spring reset mechanism comprises an upperpart bearing platform, a lower part bearing platform, a vertical rod and spring reset components; the vertical rod is install between the upper part bearing plate and the lower part bearing platform,and penetrates out of bottom faces of the upper part bearing plate and the lower part bearing platform; the spring reset components, used for enabling the upper part bearing platform and the lower part bearing platform to automatically reset, are respectively installed at the parts, which respectively extend out of the upper part bearing platform and the lower part bearing platform, of the vertical rod; the crab-shaped swinging mechanism comprises the lower part bearing platform, diagonal draw bars, diagonal support bars and bases; the diagonal draw bars are symmetrically installed at the twosides of the lower part bearing platform, and the other ends of the diagonal draw bars are connected with the diagonal support bars. The self-resetting swing shock-isolation system provided by the invention can dissipate earthquake energy by swinging during an earthquake so as to protect an upper part structure. When the earthquake is ended, a restoring force is provided by means of structure self-weight and spring torsion, so that a reset effect is achieved.

Description

technical field [0001] The invention belongs to the field of earthquake-resistant buildings, and in particular relates to a self-resetting swaying shock-isolation system. Background technique [0002] China is a country with frequent earthquakes. The earthquake zone is widely distributed and the focal point of a large earthquake is shallow. When a large earthquake strikes, it often causes immeasurable human and financial losses. [0003] The requirement for earthquake resistance of buildings is that the main body of the structure can withstand dynamic loads exceeding its strength without damaging the ductility design, and damage to parts that are not so important to the overall integrity of the structure does not affect the overall safety of the structure, and the form of damage is non-brittle failure. [0004] The traditional seismic design is a kind of ductile design, which is to resist earthquakes by improving the fortification level of buildings, but it is inevitable tha...

Problems solved by technology

[0005] At present, there are some sliding isolation bearings that make the building move properly during the earthquake, which shows that it can effectively reduce the seismic response of the superstructure, but the reset of the building is still a big problem.
