Connected two-way isolation bearing system

Abstract

The invention relates to a connected two-way isolation bearing system. The system comprises a plurality of isolation bearings, wherein each isolation bearing comprises an upper connecting plate and alower connecting plate, a supporting plate is arranged between the upper connecting plate and the lower connecting plate, a u-shaped sliding plate is arranged on the upper surface of the supporting plate, the upper connecting plate is n-shaped, the sliding plate is located in the upper connecting plate, and balls are arranged between the upper surface of the sliding plate and the lower surface ofthe upper connecting plate; a plurality of longitudinal isolation units and a transverse isolation unit are arranged between the supporting plate and the lower connecting plate, the longitudinal isolation units are distributed in a circumferential array manner with an axis of the transverse isolation unit as a circle center, each longitudinal isolation unit comprises a connecting piece, a flange and a vertical isolation assembly, the transverse isolation unit comprises a rubber protective jacket and an isolation combination, the rubber protective jacket is in a round tube shape, and the isolation combination is arranged in the rubber protective jacket; the two isolation bearings are connected through a rubber plate. The isolation bearing system reduces horizontal quake and vertical quake of a building under the seismic action.

Description

technical field [0001] The invention belongs to the technical field of vibration control of civil engineering and construction engineering, and in particular relates to a connected two-way shock-isolation support system. Background technique [0002] Earthquake is a sudden and extremely destructive natural disaster. Seismic isolation technology can effectively reduce the damage of houses during earthquakes. The existing seismic isolation bearings include: friction pendulum isolation bearings, hyperboloid spherical isolation bearings Seismic bearings, high damping rubber isolating bearings, memory alloy isolating bearings and other forms, rubber isolating bearings are currently the most researched and relatively mature basic seismic isolation devices, and have exceeded 500 engineering projects in China Using rubber isolation bearings, including houses, bridges and highways, etc. Most of the existing seismic isolation bearings can only reduce the impact of unidirectional seis...
