Bidirectional shock insulation support

Abstract

The invention relates to a bidirectional shock insulation support which comprises an upper connecting plate and a lower connecting plate, a supporting plate is arranged between the upper connecting plate and the lower connecting plate, a first shock insulation mechanism is arranged between the supporting plate and the upper connecting plate, and a second shock insulation mechanism is arranged between the supporting plate and the lower connecting plate. The first shock isolation mechanism is composed of a rubber protection sleeve and a transverse shock absorption unit. The second shock insulation mechanism comprises a main shock absorption column and a branch shock absorption column. The upper ends of the main shock absorption column and the branch shock absorption column are fixedly connected with the lower surface of the supporting plate, and the lower ends of the main shock absorption column and the branch shock absorption column are fixedly connected with the upper surface of the lower connecting plate. A controller is arranged on the upper surface of the lower connecting plate, laser range finders are arranged at four corners of the upper surface of the lower connecting plate,and each laser range finder is connected to the controller. The invention provides the bidirectional shock insulation support to reduce horizontal shock and vertical shock of a structure under the action of an earthquake, and whether the shock insulation support is intact after the earthquake can be monitored.

Description

technical field [0001] The invention belongs to the technical field of vibration control of civil construction engineering, and in particular relates to a two-way shock-isolation bearing. 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 seismic action on the structure, but ...

Problems solved by technology

Compared with the existing technology, this application can remind the staff when to replace the shock absorber as a whole, but this shock absorber can only detect the overall failure of the shock absorber through the laser ranging sensor, and cannot detect the shock absorber.
