| Name | Isolation rubber bearing |
| Vibration isolation rubber bearing is an important structural seismic technology, which can reduce the impact and damage of earthquake on building structures by using the elastic and damping properties of rubber. Vibration isolation rubber bearings mainly include plate rubber bearings and lead core vibration isolation rubber bearings (LRB lead core vibration isolation rubber bearings) two types, they play a key role in building earthquake isolation. | 1. Plate rubber support: This support is composed of multiple layers of natural rubber and at least two layers of the same thickness of thin steel plate inlaid, bonded, vulcanized, mainly used for Bridges and other structures. It can withstand vibration and seismic loads during operation, and absorb and disperse seismic energy through elastic deformation of rubber, thus protecting the superstructure from damage. |
| 2. Lead core isolation rubber bearing (LRB lead core isolation rubber bearing) : This is a support for isolation structures, by pressing lead core into the center of the RB support. Lead core has good plastic deformation capacity and energy absorption capacity, and can be integrated with rubber bearings to follow shear deformation. The bearing combines the stability recovery device of rubber bearing and the energy absorption device of lead to form a vibration isolation device with a damping mechanism. LRB bearing adjusts the damping size by the size of lead core, has good mechanical properties, simple structure and high cost performance, and has been widely used in engineering. | |
| Features | 1. Structural requirements: The seismic isolation rubber bearing is composed of the respective advantages of steel plate and rubber, and the lead rod or viscous material is added in the manufacturing process to provide the appropriate damping ratio and lateral stiffness. |
| 2. Durability and basic mechanical properties: Vibration isolation rubber bearing has good aging resistance, oxidation resistance and high temperature resistance. Engineering investigations in Japan and other countries show that LRB supports are basically the same as RB supports, and even after 100 years of use, its internal rubber is still intact. | |
| Application scenario | Seismic isolation rubber bearings are widely used in schools, hospitals, airport terminals, museums and other important buildings and lifeline projects. By extending the natural vibration period of the structure and increasing the damping of the structure, the upward transmission of seismic energy is reduced, and the earthquake damage is greatly reduced. |
In summary, the seismic isolation rubber bearing plays an important role in the field of building isolation through its unique structure and excellent performance, effectively protecting the safety of building structures and reducing earthquake disaster losses
Vibration isolation rubber bearing (LRB/LNR) is a seismic isolation building component product developed in accordance with the current national and industry standards. The building vibration isolation rubber bearing is divided into lead core rubber bearings and natural rubber bearings. Lead core rubber bearing (LRB) is composed of lead core rod, rubber layer, steel plate and so on. Lead mandrel increases the damping of support and absorbs energy; The steel plate improves the vertical stiffness of the support, so that it can support the building structure effectively. The rubber layer gives the support the function of high elastic deformation, resetting and bearing. Therefore, the lead rubber bearing not only has high bearing capacity, but also has large damping, large horizontal displacement capacity and reset function. It is a kind of isolation device that integrates support and energy consumption. The damping coefficient of natural rubber bearing is small, which is generally only conducive to the small horizontal stiffness, in order to extend the cycle of the structure and avoid the damage of the earthquake force to the building.
