Introduction
Generally plate rubber bearings
are made of several layers of rubber sheets and thin steel plates that are vulcanized under pressure. Rectangular_/Plate rubber bearing
Circular_/Plate rubber bearing
Spherical crown_/Plate rubber bearing
Circular slope_/Plate rubber bearing
. Because_/plate rubber bearing
itself has sufficient vertical stiffness to meet large vertical loads and has good elasticity to adapt to the rotation of the beam end. It also has large shear deformation to meet the horizontal displacement of the superstructure, can produce good anti-seismic effects, and reduce the impact of dynamic loads on the superstructure and piers.
Because_/Plate rubber bearing
has excellent isotropic performance in horizontal shear to transmit multiple deformations of the superstructure. The advantages are outstanding in the application of curved bridges. In addition to the function of a general rubber bearing, this product also has the function of adjusting the position of the force-bearing base through the spherical surface rubber layer when a force effect is exerted on the beam end, and gradually distributing the force to the circular plate rubber bearing
and rubber layer to make the support evenly stressed, especially suitable for inclined bridge overpasses and other places with inclined bridges.

Classification
A rectangular (circular)_/Plate rubber bearing
_/Plate rubber bearing
_/Plate rubber bearing
(1) Function This product is made of multi-layer rubber sheets and thin steel plates inlaid and bonded together. It has sufficient vertical stiffness to bear vertical loads, can reliably transmit the reaction force of the superstructure to the pier, has good elasticity to adapt to the rotation of the beam end, and has large shear deformation to meet the horizontal displacement of the superstructure.
(2) Features: This product has been widely used in the seismic equipment of bridge construction, hydropower projects and houses. Compared with the original steel bearings, it has the advantages of simple structure, convenient installation, saving steel prices, low price, simple maintenance, easy replacement, etc. The product has a high construction height. It is beneficial to bridge planning and construction cost, and is especially suitable for bridges with small and medium loads and large displacements. It has excellent seismic isolation effect and can reduce the impact of live load and seismic force on the building.

Our country is also one of the countries with strong seismic activity of anti-seismic spherical steel bearings and is the earliest in the world to implement seismic isolation technology. countries studied. The main production companies include Yunnan Zhen'an Shock Absorbing Technology Co., Ltd. Wuxi Shengfeng Shock Absorber Co., Ltd. Liuzhou Dongfang Industrial Rubber Co., Ltd. Hebei Hengshui Zhentai Seismic Isolation Equipment Co., Ltd. and other major scientific research institutes include China Academy of Building Sciences Tsinghua University Guangzhou University Huazhong University of Science and Technology, Southeast University, etc. Rubber isolation technology has been successfully applied in some buildings in Sichuan, Yunnan, Shanxi, Xinjiang, Yunnan, Guangdong and other places. The anti-seismic spherical steel bearings cover most of the earthquake areas in my country.
