The difference between lead-core isolation bearings and ordinary isolation bearings is that a hole is made in the middle of ordinary isolation bearings, and lead is poured into them to form lead-core rubber bearings. This type of bearing not only has a high damping ratio, but also has a certain initial stiffness, which can provide the building with earthquake and wind resistance.
Lead core isolation bearing is a kind of seismic isolation and vibration reduction device, mainly composed of rubber and lead core. Its main use is in buildings, bridges, mechanical equipment and other structures for shock absorption and isolation, and to reduce the sensitivity of the structure to earthquakes and other vibrations. 
Lead core isolation bearings consist of an outer steel bearing and an inner lead core. Steel bearings are often made from high-strength steel and are designed to withstand gravity loads and other non-seismic loads from a building or bridge. The lead core serves as a seismic isolation component and has good seismic isolation capabilities.
The main function of the lead core isolation bearing is to convert the seismic force or vibration energy into heat energy through its lower stiffness and good energy absorption performance when an earthquake or other external vibration occurs, thereby reducing the stress on the building or bridge. withstand the vibration force. 
The installation steps are as follows:
-
Preparation: Prepare the required lead core isolation bearings and accessories according to the design requirements.
-
Clean the installation area: Clean the installation area to make sure the surface is flat, clean, and clear of any debris and dirt.
-
Mounting the bearing: Place the lead core isolation bearing on the prepared mounting area. Use shims or bearing caps for padding as required by the design.
-
Adjust the position of the support: After determining the position of the support, use a level or adjustment tool to adjust the level of the support.
-
Fix the support: Fix the support to the structure or foundation by bolts or welding. Make sure it is firmly fixed and adjust the preload as required.
-
Connection structure: If necessary, connect the structure to the lead-core isolation bearing to ensure the stability and sealing of the connection.
-
Acceptance and testing: After the installation is completed, the bearings and structure will be accepted, and corresponding tests and adjustments will be made to ensure the isolation effect of the bearings and the stability of the structure.
Precautions:
- Pay attention to safety during installation to avoid harming yourself and others.
- Lead core isolation bearings should be inspected before installation to ensure that there is no damage or defects.
- Operate according to design requirements to ensure correct connection and fixation of supports and structures.

Seismic isolation bearing is a device commonly used in building and bridge structures. Its main function is to reduce the impact of earthquakes, wind loads and other dynamic loads on the building structure, thereby providing higher structural stability and safety. Seismic isolation bearings can effectively isolate the energy transmitted from seismic waves to the structure, reduce post-earthquake damage, and protect the integrity of the building and its internal equipment.

Rubber isolation bearing is a kind of isolation device made of rubber material. It is highly compressible and deformable, and can quickly absorb and disperse energy during earthquakes, thereby reducing the vibration of buildings. Rubber isolation bearings usually consist of one or more layers of rubber gaskets that can be adjusted as needed to meet different load and vibration requirements. Rubber isolation bearings also offer the advantages of long service life, low maintenance costs and high reliability. Seismic isolation bearings can be divided into many types according to their structure and materials. The most common types include rubber isolation bearings, Lead core isolation bearings consist of an outer steel bearing and an inner lead core. Steel bearings are often made from high-strength steel and are designed to withstand gravity loads and other non-seismic loads from a building or bridge. The lead core serves as a seismic isolation component and has good seismic isolation capabilities. The main function of the lead core is to convert seismic force or vibration energy into heat energy through its lower stiffness and good energy absorption performance when earthquakes or other external vibrations occur, thereby reducing the vibration force experienced by buildings or bridges. . It should be pointed out that the quality and size of lead-core isolation bearings need to be strictly controlled during the design and installation process to ensure their working effect and safety. In practical applications, structural engineers need to reasonably select and calculate the number, size and layout of isolation bearings based on the characteristics and seismic conditions of the specific building or bridge to achieve the isolation effect. support, The high-damping rubber bearing consists of an outer metal container and an inner lead rubber material. The outer container is usually made of steel or aluminum alloy and has sufficient strength and stability. The internal lead rubber material is a high-damping material with low stiffness and good energy absorption capabilities. It dissipates the energy of earthquakes or other vibrations through the elastic deformation of rubber and frictional damping of the internal metal container. 、
Elastic shock-absorbing bearing, also known as elastic bearing or rubber bearing, is a shock-absorbing device used in building structures. Its main function is to reduce the stress on the building structure and protect the safety of buildings and personnel by absorbing and dispersing energy under the action of earthquakes or other external forces. Elastic shock-absorbing bearings are usually made of rubber materials and have excellent elastic properties and durability. Its basic structure consists of two upper and lower metal plates clamped by rubber gaskets to provide vertical support under static load. When earthquakes or other external forces act on a structure, the gaskets deform through twisting or compression, absorbing and dissipating energy. In this way, the elastic shock-absorbing bearing can reduce the impact force on the structure and effectively reduce the vibration response of the structure.
Friction pendulum isolation bearing is a kind of earthquake isolation device used in building structures. It mainly achieves the seismic isolation effect by using friction and swing, reducing the stress on the building structure under earthquakes or other external forces, and reducing the destructiveness of earthquakes to buildings.
