LRB Lead isolation rubber bearing

Lead rubber bearing have been sold to Netherlands as isolation device used in bridge and it has a big market in Oman,Saudi Arabi ,Kenya , Mexico, Nigeria ,Lebanon etc.

Our lead rubber bearing is more professional than MAGEBA, BAUTECHNIK GMBH , FIP INDUSTRIALE etc.

1. Description of lead-cored rubber bearing (Seismic Isolator)

The Lead Rubber Bearing (LRB), Vulcanized rubber layers are laminated between steel plates to form a flexible structural support. It is installed as a Damping Equipment under building structures so as to control the tremor of structure against the loads of earthquake2. Application of lead-cored rubber bearing

Base Isolation System, which is a branch of manual technique to reduce the tremor of structure, is widely applied to the large sized structures such as road bridges, rail bridges and nuclear power station to minimize damages from dynamic loads like earthquake.

3. Special Features of lead-cored rubber bearing

* Strong Points

* Property of Lead as a Suitable Material for Earthquake Absorbing Work

* The Economic Design

* The More Excellent Safety

* Easy Installation

4. Function of lead-cored rubber bearing The rubber in the isolator acts as a spring. It is very soft laterally but very stiff

vertically. The high vertical stiffness is achieved by having thin layers of rubber

reinforced by steel shims. These two characteristics allow the isolator to move

laterally with relatively low stiffness yet carry significant axial load due to their high

vertical stiffness. The lead core provides damping by deforming plastically when the

isolator moves laterally in an earthquake.

For more than two and a half decades Dynamic Isolation Systems has been helping architects, engineers, businesses and institutions match the right earthquake protection technology to the specific needs and requirements of their individual structures.
