Isolation bearing

Material: high damping rubber

Model: standard size, custom

Application: shock absorption and seismic isolation

Applicable to: bridges, building construction

Seismic isolation bearings are shock-absorbing devices used in engineering structures. Through high-damping materials or structural design, they significantly consume external vibration energy (such as earthquakes, wind loads, etc.), reduce structural impacts, and protect the safety of buildings or bridges.

Features:
1. Compared with ordinary rubber bearings, high-damping rubber bearings can effectively dissipate seismic energy and greatly reduce the seismic response of the structure.

2. After deformation, it can quickly return to its original state to ensure the normal use of the structure after an earthquake.

3. By designing the number of stiffening steel plates and the performance of the rubber layer, the high-damping bearing can have a higher vertical bearing capacity and can meet the weight support requirements of different types of habitual structures.

4. The use of high-damping rubber materials has good aging and fatigue resistance, and can maintain stable mechanical properties during long-term use.

Structure:
1. Rubber layer: mainly made of high-damping rubber material, it is the key part to provide elasticity and damping, and can produce large elastic deformation to dissipate energy during earthquakes.
2. Stiffening steel plate: The steel plate and rubber layer are alternately overlapped and bonded together through a vulcanization process, which can enhance the support and vertical bearing capacity and constrain the lateral deformation of the rubber. Make the bearing have good mechanical properties.
3. Connecting parts: The upper and lower ends of the bearing are used for reliable connection between the bearing and the upper and lower parts of the structure. They are generally made of high-strength steel to ensure a stable connection under earthquake loads.

Application areas:
In buildings: such as: hospitals, schools, office buildings, etc.
In bridges: such as: viaducts, large-span bridges, etc.
