AI Technical Summary

Technical Problem

In traditional seismic design, seismic energy cannot be effectively dissipated, structural damage is irreversible, and lead-core rubber seismic isolation bearings pose a pollution problem.

Method used

It adopts a steel spring laminated rubber plate structure, with internal damping springs to absorb vertical forces. Through the dual control mechanism of damping steel springs and damping body, the horizontal deformation of the rubber layer is reduced, the bearing capacity of large shear force is improved, the peeling of rubber and steel plate interface is avoided, and the aging rate is reduced.

Benefits of technology

It achieves reliable vibration reduction, improves the load-bearing capacity against large shear forces, extends the service life of the bearing, solves the pollution problem, and has a simple structure and novel design.

Abstract

A vibration-controlled elastic bearing with steel spring laminated rubber sheet is provided, comprising an upper connecting plate, a lower connecting plate, and a damping body. Multiple vertically arranged damping springs for absorbing vibration energy are evenly distributed inside the damping body. The upper and lower ends of the damping springs, which penetrate the damping body, are respectively connected to the upper and lower connecting plates via an upper sealing plate located above the damping body and a lower sealing plate located on the lower end face of the damping body. This invention optimizes the internal structure of the elastic bearing to achieve dual vibration control, ensuring reliable damping while improving the load-bearing capacity for large shear forces. It solves the pollution problem associated with traditional core rubber seismic isolation bearings. While the damping springs bear the main dynamic load, it reduces fatigue damage to the damping body, lowers its aging rate, and extends its service life.
