Ordinary rubber bearings are made of natural rubber sheets or chloroprene rubber sheets laminated with steel plates. They have good linear properties and can significantly reduce the seismic effects of the structure and suppress the high dielectric reaction of the structure. This type of support does not provide damping. It is difficult to move the support seat during an earthquake. In actual projects, it must be used in conjunction with various dampers.。
The building isolation bearing product is a special bearing used in the earthquake isolation design of buildings. Its main purpose is to protect buildings from earthquakes. By installing isolation bearings, the vibration force experienced by buildings during earthquakes can be reduced and the structure of the building and the safety of personnel can be protected.
A seismic isolation bearing is a seismic 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.
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.
The installation steps of the isolation bearing are as follows:
-
Preparation work: Confirm the structural and design requirements of the building, and determine the type and quantity of earthquake isolation supports.
-
Determine the installation position: According to the design requirements, determine the installation position of the isolation bearing and mark the center point of the bearing.
-
Trim the foundation: According to the size of the isolation bearing, trim and smooth the surface of the foundation to be installed, and ensure that the surface of the foundation is not damaged.
-
Install the fixing bolts: Pre-embed the fixing bolts on the surface of the foundation, arrange them according to the requirements of the isolation bearing, and ensure that the bolts are firmly connected to the foundation.
-
Install the isolation bearing: Place the isolation bearing on the foundation, align the fixing bolt holes, and use a wrench to connect the isolation bearing to the fixing bolts.
-
Adjust the height of the support: According to the design requirements, use adjustment bolts or adjustment pads to adjust the height of the isolation support to ensure a smooth connection between the support and the upper part of the structure.
-
Repeated inspection and fixation: Repeatedly check the installation position, height and fixation firmness of the isolation bearing, and perform final fixation after adjustment.
-
Completion acceptance: After completing the installation of the isolation bearing, carry out relevant acceptance work to ensure that the installation quality meets the design and specification requirements.

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.
Seismic isolation bearings can be divided into many types according to their structure and materials. The most common types include rubber isolation bearings,Lead isolationsupport,High damping rubber bearing、Elastic shock-absorbing bearings and tensile friction pendulum shock-absorbing isolation bearings.
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.
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.
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.
In general, as an important structural device, the isolation bearing can effectively reduce the impact of earthquakes and other dynamic loads on the building structure and improve the stability and safety of the building. Rubber isolation bearings,Lead core isolation bearing、High damping rubber bearing、Elastic shock-absorbing bearings and tensile friction pendulum shock-absorbing isolation bearingsThey are currently the main seismic isolation devices used. Each has different structural and material characteristics and can be selected and applied according to project requirements.
