Shock isolation system based on rubber damping and used for high-rise building

Abstract

The invention relates to a shock isolation system based on rubber damping and used for a high-rise building. The shock isolation system comprises an upper connecting plate, a lower connecting plate, adamping mechanism arranged between the upper connecting plate and the lower connecting plate and a reinforcing plate connecting the upper connecting plate to the lower connecting plate, wherein sealing plates are connected between the upper connecting plate and the lower connecting plate; a limiting column is connected between the sealing plates; a separation plate is arranged on the center of the limiting column; upper and lower ends of the separation plate are connected to tetrafluoroethylene boards; upper and lower ends of the tetrafluoroethylene boards are connected to damping mechanisms;each damping mechanism comprises a plurality of rolling shafts which connect the tetrafluoroethylene boards to the sealing plates, and are axially arranged along the limiting column, wherein the shaft centers of the outer ends of the rolling shafts are connected through connecting rods, and rubber columns are arranged in gaps of adjacent rolling shafts between the sealing plates and the tetrafluoroethylene boards. According to the shock isolation system based on rubber damping and used for the high-rise building disclosed by the invention, the rolling shafts, the rubber columns and the reinforcing plate are mutually cooperated, so that a vibration amplitude of the building is reduced, impact, on the building, of earthquake waves is resisted, and the center force-bearing degree of the building is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of shock absorption and isolation of buildings, and in particular relates to a shock isolation system for high-rise buildings based on rubber shock absorption. Background technique [0002] Earthquake is an unpredictable and sudden natural disaster. Its occurrence is often accompanied by huge destructive power, resulting in the collapse of countless houses, casualties and property losses. China's high-intensity earthquake areas are widely distributed, and China's urbanization is developing rapidly Therefore, effective anti-seismic measures must be adopted to improve the anti-seismic performance of buildings. At present, the traditional anti-seismic technology can no longer fully meet the needs of the society. Many earthquake isolation engineering cases in the world have proved that the reasonable use of anti-seismic technology can effectively reduce the seismic effect of buildings and further improve the ant...

AI Technical Summary

Problems solved by technology

[0003] The existing anti-seismic bearings are usually made of rubber or PTFE filled between the upper bearing plate and the lower bearing plate. The anchoring force is poor, and the upper bearing plate and the lower bearing plate are easily damaged when a strong earthquake occurs. As a result, the anti-seismic bearing structure is not stable and the anti-seismic ability is not strong
