Supply of Zhengzhou Plate Bridge Bearing Specifications

**Plate Rubber Bearing** The plate rubber bearing is a type of bridge bearing product made from multiple layers of natural rubber embedded, bonded, and vulcanized with at least two layers of thin steel plates of the same thickness. Plate rubber bearings possess sufficient vertical stiffness to withstand vertical loads and reliably transfer the pressure from the superstructure to the piers and abutments. They also have good elasticity to accommodate the rotation at the ends of the beams and a large shear deformation to meet the horizontal displacement of the superstructure. Plate bearings can be classified by shape into two types: rectangular and circular. They can also be categorized based on their ability to provide horizontal displacement, which includes PTFE sliding bearings and ordinary rubber bearings. The plate rubber bearing is a new type of bridge bearing. It has advantages such as simple structure, easy processing and manufacturing, low material consumption, low cost, and convenient installation. It has been widely used in bridge engineering both domestically and internationally. In China, the development and testing of plate rubber bearings began in 1965 by institutions such as the Shanghai Rubber Products Research Institute, the Shanghai Municipal Engineering Research Institute, and the Shanghai Municipal Design Institute, and they have 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 now been in use for 25 years. Currently, plate rubber bearings have become a widely adopted and popular type of bearing for highways and urban bridges in China. Technical conditions for highway bridge plate rubber bearings were established in 1988, with 24-hour technical support available for new and existing customers.
