The description of isolation bearings

Lead rubber bearing is based on general laminated rubber bearings, pouring the
Lead in
to the bearing center, which is a seismic bearing damping performance
Improvement of rubber bearings. By changing the lead core section size of the
Bearings, lead rubber bearing can change the effective level of equivalent stiffness
And equivalent damping ratio. 

Our production capacity is not limited to this, please send your requirements to us.

Lead Rubber Bearing for Bridge (seismic isolators)

Bridge bearings and expansion joint are important parts of whole bridge components, but the amount money that spent on bridge bearing and expansion joint is only 2-3.5%, it is absolutely a wise choice to evaluate it within the whole project to prevent failed choice bringing unnecessary costs. 


The typeof isolation bearings

1. According to the degree of damping points

(1)Lead rubber bearings
LRB rubber bearing, applied to building and bridge constructions, is a practical
And cost-effective choice for seismic isolation. It is composed of 
laminated
Elastomeric bearing
 pad, with lead in the center of bearing. This series of bearing
Is suitable for 8 degrees and the earthquake intensity area of highway and
Municipal bridge. 



(2)High damping rubber bearings
Its structure is the same as ordinary laminated rubber bearings, high damping
Rubber bearing is improved through rubber formula, so that the rubber material
Damping is increased, so that the bearing's damping ratio can reach 15-18%. 
This series of bearing is suitable for 9 degrees earthquake intensity area of
Highway and municipal bridge.

The advantage of isolation bearings

1. Stiff and strong in vertical direction but flexible in horizontal direction. 
2. Allow the buildings to retain their original shapes and position owing to the high
Elastic force of rubber. 

3. Capable to adjust damping amount just by changing the number of lead plugs. 
4. Excellent vertical load capacity ranging from 5 tons to 2000 tons
5. Reduce the ground acceleration by extending the structure vibration period. 
6. High durable and elasticity of the rubber part - not suffer any damages during and
After earthquake. 

7. Easy to install without a separated damper. 
8. Low maintenance. 
9. Stable bilinear behavior

As your request, the lead rubber bearing can be manufactured in rectangular or
Round shapes. Custom sizes and designs are also welcomed. 





Lead Rubber Bearing for Bridge (seismic isolators)



Q: 
Where is the lead rubber bearing used to? 

A: The product has been successfully used in a broad range of applications which
Include: Bridges, viaducts, high rise buildings, stadiums and dams. 





Q: 
What is the good successful case of the isolation bearing

A: In fact, as early as the MID-1990-s, building isolation rubber bearing showed
Its excellent isolation 
performance. The region of an earthquake, Osaka and kobe, 
Japan is the real one. On January 17, 1995, Japan kobea 7.2 -magnitude
Earthquake, caused the shocking heavy losses. In the earthquake, 35 kilometers
From the epicenter of the west of the men in the post office base isolation
Technology has played a very good isolation 
damping effect, it is in the field of
Earthquake hazard level has reached the degree of 7 (equivalent to China's
Earthquake intensity of 9~10 degrees), in the earthquake and after the earthquake, 
The whole building is as usual. 





Q: 
How can I get some samples? 
A: We are honored to offer you samples. New clients are expected to pay for the
Postage, the samples are free for you, this charge will be deducted from the
Payment for formal order.
