Product Description

Overview

Principles of Construction

Natural rubber isolation bearings are a type of seismic device designed specifically for bridge engineering, mainly made of natural rubber materials, used to support bridge structures and reduce the impact of external factors such as earthquakes on bridges.
This type of support absorbs and disperses vibration forces generated by earthquakes and other factors through the elastic properties of rubber. During an earthquake, rubber bearings undergo elastic deformation, which consumes seismic energy and significantly reduces the damage to bridges caused by earthquakes. In addition, natural rubber seismic isolation bearings can provide certain horizontal displacement and rotation capabilities, enabling bridge structures to better adapt to different loads and environmental conditions, ensuring the stability and safety of the bridge.
In bridge engineering, natural rubber isolation bearings have been widely used, which can effectively extend the natural vibration period of bridges, reduce the impact of earthquakes on bridges, and protect the integrity and safety of bridge structures.

 

Product advantages
The main advantages of natural rubber seismic isolation bearings in bridge engineering include excellent shock absorption performance, strong bearing capacity, high durability, and strong adaptability.
1. Excellent shock absorption performance: Natural rubber materials have excellent elasticity, which can absorb and disperse external impact forces, effectively reducing structural vibration. In bridge engineering, this can significantly reduce the damage to bridge structures caused by natural disasters such as earthquakes and wind loads, and protect the safety and stability of bridges.
2. Strong bearing capacity: Natural rubber isolation bearings are designed reasonably and can withstand large loads while maintaining structural stability. This enables the bridge to be safely used under various conditions, ensuring smooth traffic and safe travel for people.
3. High durability: Natural rubber materials have good aging resistance and can maintain a long service life in various harsh environments. In addition, the maintenance cost of rubber bearings is relatively low, which reduces the overall cost of bridge engineering.
4. Strong adaptability: Natural rubber seismic isolation bearings can also adapt to small deformations in bridge structures, maintaining the stability and smoothness of the bridge. This is very important for driving, as a flat bridge deck can improve driving comfort and also help extend the service life of the bridge.
 

Specification

Product Name	linear natural rubber bearing(LNR)
Working Principle	The working principle of natural rubber isolation bearings is mainly to use the elastic properties of rubber to absorb and disperse vibration forces, providing effective seismic protection for bridge engineering. In bridge engineering, natural rubber isolation bearings undergo elastic deformation when subjected to external loads such as earthquakes, vehicle travel, or wind loads. This deformation can absorb and disperse the vibration force generated by external loads, thereby reducing the vibration response of the bridge structure. In addition, natural rubber seismic isolation bearings can provide certain horizontal displacement and rotation capabilities, enabling bridge structures to better adapt to different loads and environmental conditions, avoiding damage caused by uneven stress. This type of support can not only effectively extend the service life of the bridge, but also improve the comfort and safety of driving.
Product Structure	Natural rubber isolation bearings are mainly composed of upper elastic plates, isolation rubber, lower elastic plates, and possibly sandwich thin steel plates, providing effective isolation support for bridge engineering. Upper elastic plate: generally made of steel plate and rubber compression block, used to disperse the upper load and evenly apply it to the isolation rubber. Seismic isolation rubber: As the core of seismic isolation bearings, it is a high-strength, wear-resistant, and aging resistant rubber product. It has good elasticity and seismic isolation performance, which can alleviate the vibration and impact caused by earthquakes, wind loads, etc., thus protecting the bridge structure from damage. Lower elastic plate: Similar to the upper elastic plate, it is pressed from steel plates and rubber blocks, used to receive lower loads and transfer them to the bridge foundation. In addition, sandwich thin steel plates may be added to the rubber layer, which are tightly bonded to the rubber layer. When the isolation bearing is subjected to vertical loads, the lateral deformation of the rubber plate is constrained, thereby endowing the isolation bearing with greater vertical bearing capacity and vertical stiffness.
Applications	Rubber isolation bearings are mainly used in bridge engineering to enhance the safety and durability of bridges. In bridge engineering, natural rubber isolation bearings can effectively balance the longitudinal and transverse forces caused by vehicle traffic, reduce bridge vibration and noise, and significantly improve the safety and durability of bridges. Specifically, it can be used for various types of bridges, such as concrete beam bridges. Through its elastic and damping properties, it absorbs and dissipates energy generated by external loads such as earthquakes, vehicle travel, or wind loads, providing effective seismic protection for bridge structures. In addition, natural rubber seismic isolation bearings can also adapt to the deformation of bridge structures caused by temperature changes, concrete shrinkage and creep, and other factors, maintaining the stability and smoothness of the bridge, and improving the comfort and safety of driving.
