Overview
Principles of Construction
Building isolation bearings are a type of support device designed to meet the isolation needs of buildings. By installing these bearings between the foundation and the superstructure, a soft connection can be achieved, while also consuming seismic energy during natural disasters and reducing damage to the superstructure. Its main product categories include natural rubber isolation bearings (LNR), lead rubber isolation bearings (LRB), and high damping rubber isolation bearings (HDR)
Product advantages
1. Strong vertical bearing capacity: Building isolation rubber bearings have strong vertical bearing capacity, which can stably support buildings and ensure their normal use. This bearing capacity enables the isolation rubber bearings to maintain small compressive deformation when bearing the self weight and live load of the building, thereby ensuring the stability of the structure.
2. Large horizontal deformation capacity: Isolation rubber bearings have a large horizontal deformation capacity and can release some horizontal seismic effects under earthquake action. This deformation ability helps to reduce the direct impact of earthquakes on buildings and lower the seismic response of structures.
3. Elastic reset characteristics: Building isolation rubber bearings have elastic reset characteristics, which can automatically restore the building to its original position after an earthquake. This characteristic helps to reduce residual deformation of buildings after earthquakes and improve the structural resilience.
4. Good durability: Isolation rubber bearings have good durability, with excellent properties such as low cycle fatigue resistance, heat air aging resistance, ozone aging resistance, acid resistance, and water resistance. These properties enable the isolation rubber bearings to have a long service life, which can be the same as the service life of the building, reducing the cost of replacement and maintenance.
5. High damping performance: Some seismic isolation rubber bearings, such as lead core rubber bearings, improve the damping effect of the bearings by embedding lead cores in the rubber bearings. This high damping performance enables more effective consumption of seismic energy inside the support, further enhancing the seismic performance of the support

The working principle of building isolation rubber bearings is mainly based on their unique structural characteristics and material properties, which absorb and dissipate seismic energy through the elastic deformation of rubber.
When a building is subjected to seismic waves, the rubber layer of the isolation rubber bearing will undergo elastic deformation. This deformation can absorb seismic energy and reduce the response of the structure to seismic vibrations. Meanwhile, the steel plate in the support serves as a reinforcing material, which can constrain the lateral deformation of the rubber layer, improve the vertical bearing capacity of the support, and enable it to withstand significant horizontal deformation without instability. In this way, the seismic effect is greatly reduced, and the safety of the upper structure and its attachments is effectively guaranteed |

Product Structure
|
Building isolation rubber bearings are mainly composed of multiple layers of rubber and steel plates (sometimes including lead cores) alternately stacked and combined.
Specifically, the upper components of seismic isolation rubber bearings are generally composed of upper spring plates, locking plates, connecting bolts, etc. Among them, the upper spring plate is pressed from steel plates and rubber blocks, used to disperse the upper load and evenly apply it to the isolation rubber; The locking plate is made of thick steel plate and is used to fasten the upper spring plate when subjected to load, preventing loosening and deformation due to vibration; The connecting bolt is also an important component for fastening the upper spring plate.
And isolation rubber is the core component of isolation bearings, which is a high-strength, wear-resistant, and aging resistant rubber product with excellent elasticity and isolation performance. It can alleviate vibration and impact caused by earthquakes, wind loads, etc., thus protecting the upper structure from damage. In addition, the laminated steel plate is the "skeleton" of the isolation bearing, the laminated rubber is the "muscle" of the isolation bearing, the rubber surrounding the outer layer is the "skin" of the isolation bearing, and the lead core (in core type bearings) is the "ligament" of the isolation bearing, which enhances damping and energy consumption |

Applications
|
Building isolation rubber bearings are widely used in various building structures such as high-rise buildings, bridges, factories and industrial facilities, government and public buildings, schools and hospitals, as well as nuclear power plants and chemical plants.
High rise buildings: In areas with frequent earthquakes, isolation rubber bearings can effectively reduce the vibration and impact caused by earthquakes, and improve the seismic performance of buildings.
Bridges: Isolation rubber bearings can reduce the impact of vibration on bridge structures and extend the service life of bridges. For example, both the Hong Kong Zhuhai Macao Bridge and the San Francisco Bay Area Bridge have adopted seismic isolation bearing technology to improve their seismic performance.
Factory buildings and industrial facilities: These buildings often face vibrations and impacts from mechanical equipment, and seismic isolation rubber bearings can reduce the damage to building structures caused by these vibrations and improve equipment efficiency.
Government and public buildings: These buildings need to accommodate a large number of people and require a long service life and good safety performance. Isolation rubber bearings can reduce the vibration and vibration experienced by buildings, providing a more comfortable and safe environment for use.
Schools and hospitals: These public buildings require higher safety during earthquakes, and seismic isolation rubber bearings can significantly enhance their seismic resistance and reduce damage caused by earthquakes.
Nuclear power plants and chemical plants: These important industrial facilities can ensure the normal operation of key equipment and reduce the occurrence of secondary disasters by using seismic isolation rubber bearings.
In addition, building isolation rubber bearings can also be used in beams, columns and other parts of building structures such as commercial complexes and office buildings, effectively improving the isolation performance of buildings and enhancing their safety. |
