Supply of Zhengzhou Plate Bridge Bearing Specifications

**Plate Rubber Bearing** is a type of bridge bearing product made by embedding, bonding, and vulcanizing multiple layers of natural rubber with at least two layers of thin steel plates of the same thickness. Plate rubber bearings have sufficient vertical stiffness to support vertical loads and can reliably transfer the pressure from the superstructure to the piers; they possess good elasticity to adapt to the rotation at the beam ends; and they have significant shear deformation to accommodate the horizontal displacement of the superstructure. Plate bearings can be categorized by shape: rectangular and circular. They can also be classified based on the ability to provide horizontal displacement: PTFE sliding bearings and ordinary rubber bearings. **Plate Rubber Bearings** are a new type of bridge bearing. They have advantages such as simple structure, easy processing and manufacturing, low sodium use, low cost, and convenient installation. They are currently widely used in bridge projects both domestically and internationally. In China, plate rubber bearings began to be developed and tested in 1965 by institutions such as the Shanghai Rubber Products Research Institute, Shanghai Municipal Engineering Research Institute, and Shanghai Municipal Design Institute, and have since been used in various highway bridges in Guangdong, Shanghai, Shandong, Guangxi, Fujian, Jiangsu, Zhejiang, and Anhui. The first highway bridge in the country to use plate rubber bearings was in Zhaoqing, Guangdong, which has been in use for 25 years. Currently, plate rubber bearings have become a widely adopted and popular type of bearing for domestic highways and urban bridges. The technical conditions for plate rubber bearings for highway bridges were established in 1988. We provide 24-hour technical support and welcome new and old customers.
