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.

Product Description

Introductions of spherical bearings:
 
Spherical bearing force transmission is reliable and rotation is flexible, it not only has pot rubber bearing capacity, allowable bearing displacement and better adapt to support angle, has the following advantages compared with the pot bearings: 
 
(1)Spherical bearing transfer force through spherical face, necking phenomenon does not appear, the reacting force in the concrete is relatively uniform. 
(2) Spherical bearing by sliding spherical PTFE plate to achieve the support of turning process, the small rotating torque, and rotational torque is only related to the friction coefficient of the spherical bearing and radius of spherical, has nothing to do with the rotating angle of bearing size. Therefore, it is especially applicable to the rotation angle, the design angle up to 0.05rad. 
(3) The rotation performance of the bearings is consistent, which is suitable for wide bridge and curved bridge. 
(4) Bearing without rubber bearing pressure, there is no effect on the performance of rubber aging rotating bearings, especially with the low temperature area.

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.





Some typical spherical bearing types
QZ spherical bearing characteristic
QZ spherical bearing has great bearing capacity,large displacement and large turning angles, so it is more suitable for wide bridge and curved bridge.No rubber is used in the spherical bearings for bridge,so it never happen that brittle rubber caused by low temperature affecting the bearing rotation,and bridge spherical bearing is especially suitable for cold areas.

Advantage of QZ spherical bearing
1. The spherical rubber bearing can not force the shrinkage neck phenomenon, and the  reaction force on the concrete is relatively uniform;  
2. Spherical bearing by sliding spherical PTFE plate to achieve the support of turning process, the small rotating torque, and rotational torque and is only related to the coefficient of friction of the spherical bearing radius and Teflon plates, has nothing to do with the bearing angle, especially suitable for the requirements of high angle, corner design up to 0.05rad;
3. The QZ spherical bearing is consistent with the anisotropic rotation performance, which is suitable for wide bridge and curved bridge;
4. The bearing products do not have rubber bearing, and there is no influence of rubber aging on the rotation performance of bearings, especially suitable for low temperature regions.

Classification of QZ spherical bearing
QZ spherical bearing is subjected to vertical load and rotational kinetic energy, and the horizontal displacement characteristics are classified according to their horizontal displacement characteristics:
1. One-way movable QZ spherical type bearing: bearing the one-way horizontal load, with 
  the longitudinal displacement performance, code ZX;
2. Two way movable QZ spherical bearing: with multi direction displacement performance,  
  code DX;
3. Fixed bearing: under horizontal load, no displacement, code GD.

High Quality Spherical Rotating Steel Bearing to Leabanan

Technology performance
1. The rotation angle of the support is divided into 0.01,0.05 and 0.02rad, which can be increased according to the requirement.
2. The vertical bearing capacity of 1000-200000KN is divided into 16 levels, and the bearing capacity of the bearing is 10%.
3. Coefficient of friction: Normal temperature type μ≤0.03; Hardy type μ≤0.05.
4. Displacement of bearing design:
  a.bridge in axial direction: ±50,±100,±150mm
  b.transverse direction of bridge: ±20mm
  The design displacement can be changed according to the engineering requirements.



Function of QZ spherical bearing
QZ spherical rubber bearing is through the spherical force, has no force of the phenomenon of shrinkage, the role of the anti force in the concrete is more uniform;QZ spherical type bearing by sliding spherical PTFE plate to achieve the support of turning process, the small rotating torque, and rotational torque and is only related to the coefficient of friction of the spherical bearing radius and Teflon plates, has nothing to do with the bearing angle.So it is especially suitable for the requirements of large angle, the design of the rotation angle of up to 0.05rad above.The rotation performance of bearings is consistent, and it is suitable for wide bridge, curved bridge, and so on. The bearings do not have rubber bearing. There is no influence of rubber aging on the rotation performance of bearings, especially in low temperature regions.
