Lead core seismic isolation rubber bearings are mainly used in the following fields:
1. Construction field
New buildings: For important public buildings such as hospitals, schools, museums, and high-rise buildings that require high seismic resistance, lead core isolation rubber bearings can separate the structure from the foundation, extend the natural vibration period of the structure, reduce the effect of seismic forces on the building, reduce shaking and damage during earthquakes, and ensure the safety of personnel and equipment inside the building.
Reinforcement and renovation project: When seismic reinforcement is carried out on existing buildings, lead core isolation rubber bearings are installed between the foundation and the upper structure to improve the seismic performance of the building, extend its service life, and avoid large-scale demolition and reconstruction due to structural damage caused by earthquakes.
Special structural connections: Lead core isolation rubber bearings are used to connect corridors, connected structures, canopies, and grid roofs with the main structure, which can significantly improve the stability and seismic performance of these structures during earthquakes, enabling them to work better together during earthquakes and reduce relative displacement and damage.
2. Bridge engineering field
Highway bridges: In highway bridges crossing valleys, rivers, etc., lead core isolation rubber bearings can effectively reduce the vibration and displacement of the bridge during earthquakes, protect the structural safety of the bridge, ensure a certain level of traffic capacity after earthquakes, and facilitate rescue and traffic recovery.
Urban bridges: Elevated bridges, river crossings, and other structures in cities that require high safety standards due to their densely populated surroundings and heavy traffic flow. Lead core isolation rubber bearings can improve the reliability of bridges during earthquakes, reduce damage to bridge structures and ancillary facilities, and ensure the normal operation of urban transportation.
3. Other engineering fields
Ship engineering: Installed on the equipment base, cabin and other parts of the ship, it can reduce the vibration and noise caused by wave impact, engine vibration and other factors during navigation, improve the comfort of the ship and the stability of equipment operation, and protect the safety of equipment and personnel on board.
Transportation Engineering: Used in transportation facilities such as roads and tunnels to connect and support special areas, such as tunnel openings and the connection between roads and bridges. It can play a role in seismic isolation and reduction, improve the overall stability and seismic performance of transportation facilities, and extend their service life.
Underground engineering: such as subway stations, underground shopping malls and other underground structures, lead core seismic isolation rubber bearings can be used to reduce the impact of ground movement on underground structures during earthquakes, improve the seismic resistance of underground structures, and ensure the safe use of underground spaces.
Important facilities such as nuclear power plants: For facilities with high safety requirements such as nuclear power plants, lead core isolation rubber bearings can effectively absorb and dissipate seismic energy in extreme situations such as earthquakes, protect the safety of key equipment and structures, and prevent serious accidents such as nuclear leaks.
