Product Description
The Elastomeric Rubber Bridge Bearing Pad is a high-quality product designed to meet the specific requirements of bridge construction. It is constructed using multiple layers of rubber sheet and thin steel plate, which are carefully superimposed through pressure vulcanization. This unique composition provides the bearing with exceptional vertical stiffness, enabling it to effectively support vertical loads. Additionally, the bearing exhibits excellent elasticity, allowing it to adapt to the rotational movements of the beam end.
One of the key features of this product is its ability to undergo significant shear deformation. This characteristic is crucial in accommodating the horizontal displacement of the superstructure, ensuring optimal performance and stability. Furthermore, the Elastomeric Rubber Bridge Bearing Pad offers remarkable seismic resistance, effectively reducing the dynamic load on both the upper structure and the pier. This feature is particularly important in enhancing the overall safety and durability of the bridge.
In conclusion, the Elastomeric Rubber Bridge Bearing Pad is a reliable and versatile solution for bridge construction projects. Its superior design and exceptional performance make it an ideal choice for engineers and contractors seeking to optimize the functionality and longevity of their structures.
Features of rubber bridge bearing:
(1) Quality materials including natural rubber, neoprene complying with AASHTO standards.
(2) Allow for expansions and contractions of precast steel structure of bridges.
(3) Capable to control load distribution, meanwhile accommodate thermal and end-beam rotational movements.
(4) Vibration, sounds and shocks isolation.
(5) Avoid excessive load eccentricity and edge compression.
(6) Simple but robust structure.
(7) Lower price than laminated elastomeric bearing.
(8) High cost effectiveness.
(9) Minimal maintenance is needed.
