Product Description

Product Description

Seismic isolation rubber bearing is an efficient supporting device specifically designed to enhance the seismic performance of buildings. This product utilizes high-quality rubber materials and a special structure to effectively isolate seismic waves from impacting the building, reducing the transmission of seismic forces. Seismic isolation rubber bearings are widely used in high-rise buildings, bridges, and critical infrastructure to ensure safety and stability under seismic and other external loads.

Seismic isolation rubber bearing Features

*High Elasticity Material: The seismic isolation rubber bearing is made from highly elastic natural or synthetic rubber, providing excellent deformation capability and recovery.

*Superior Seismic Isolation Performance: Its unique structural design effectively isolates seismic waves, reducing the transmission of seismic energy and improving the building's earthquake resistance.

*High Durability: This product exhibits exceptional aging resistance and corrosion resistance, ensuring long-term use without failure.

*Easy Installation: The design of the seismic isolation rubber bearing allows for simple and quick installation, significantly enhancing construction efficiency.

Seismic isolation rubber bearings are laminated devices made from alternating layers of rubber and steel, designed to support vertical loads while allowing large horizontal deformations. By lengthening the structure's natural vibration period and dissipating seismic energy, they markedly reduce earthquake forces transmitted to the superstructure and are widely used in seismically active regions to protect buildings and bridges.

Working principle

During earthquake, the vibration from various directions will impact fixed base building and results in deformation and building or bridge damages. The high damping bearing pad is improved through high damping material, which the damping ratio can approach to 15% to 18%.

When the earthquake comes, the high damping rubber bearing will increase the horizontal displacement through rubber shear deformation and reduce friction coefficient. The large displacement can weaken the vibration from all direction and reduce the damage of building and bridges.

Advantages

Significantly Reduces Vibrations: The seismic isolation rubber bearing effectively lowers vibrations caused by earthquakes and wind loads, protecting the safety of buildings and internal facilities.

Extends Structural Lifespan: By reducing the impact of external loads on the structure, it decreases material fatigue and extends the building's service life.

Enhances Living Comfort: Effectively reduces vibrations inside buildings, providing a higher comfort level for living and working environments.
