Supply of Zhengzhou Plate Bridge Bearing Specifications

**Plate Rubber Bearing** The plate rubber bearing is a 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. The plate rubber bearing has sufficient vertical stiffness to withstand vertical loads and can reliably transfer the pressure from the superstructure to the piers; it has good elasticity to adapt to the rotation at the beam ends; it allows for significant shear deformation to accommodate horizontal displacement of the superstructure. Plate bearings are categorized by shape into two types: rectangular and circular. They are further classified based on whether they can provide horizontal displacement: polytetrafluoroethylene sliding plate bearings and ordinary rubber bearings. The plate rubber bearing is a new type of bridge bearing. It features a simple structure, easy manufacturing, low material usage, low cost, and convenient installation. It has been widely used in bridge construction both domestically and internationally. In China, the development and testing of plate rubber bearings began in 1965 at institutions such as the Shanghai Rubber Products Research Institute, the Shanghai Municipal Engineering Research Institute, and the Shanghai Municipal Design Institute. They have been used in various highway bridges in regions such as Guangdong, Shanghai, Shandong, Guangxi, Fujian, Jiangsu, Zhejiang, and Anhui. The first highway bridge to use plate rubber bearings in the country was in Zhaoqing, Guangdong, which has been in service for 25 years. Currently, plate rubber bearings have become a commonly used and popular bearing form in domestic highway and urban bridges. The technical conditions for highway bridge plate rubber bearings were established in 1988. 24-hour technical support awaits new and old customers. Phone: 13803187842 Website: www.hsjyxs.com
