Companies: Zaoqiang Dacheng Rubber Co., Ltd.The description ofisolation bearingsLead rubber bearing is based on general laminated rubber bearings,pouringthe
Lead intothe bearing center,which isa 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 productioncapacity is not limited to this, please send your requirements to us.HALF FINISHED PRODUCTS
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 awise choice to evaluate it within the whole project to prevent failed choice bringing unnecessary costs.
The typesof isolation bearings1.According to thedegree of dampingpoints(1)Lead rubber bearings
LRB rubber bearing, applied to building and bridge constructions, is apractical
And cost-effective choice for seismic isolation. It is composed oflaminated
Elastomeric bearingpad,with lead in the center of bearing.This series of bearing
Is suitable for 8degrees and the earthquake intensity area of highway and
Municipal bridge.
(2)High dampingrubber 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 9degrees earthquake intensity area of
Highway and municipal bridge.CLIENTS CAME TO CHECK FINISHED PRODUCTS

The advantage of isolation bearings1.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 5tonsto 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 aseparated damper.
8.Low maintenance.
9. Stable bilinear behavior.As your request, theleadrubber bearing can be manufactured in rectangular or
Round shapes. Custom sizes and designs are also welcomed.
Q:
Whereis thelead rubber bearing used to?A:The product has been successfully used in abroad range of applications which
Include: Bridges, viaducts, high rise buildings, stadiums and dams.
Q:
What is the good successful case of theisolation bearingA:In fact, as early as the MID-1990-s, building isolation rubber bearing showed
Its excellent isolationperformance. 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 avery good isolationdamping 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 Iget 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 fromthe
Payment for formal order.
