Abstract

A high-pressure bearable scale type bridge rubber bearing is disclosed, which comprises spring rubber vibration reduction pad assemblies, a flexible steel plate assembly and a rubber bearing body. The rubber bearing body comprises an outer rubber portion and an inner rubber portion; the outer rubber portion is wrapped around the outside of the spring rubber vibration reduction pad assemblies and the flexible steel plate assembly; the spring rubber vibration reduction pad assemblies are arranged on the upper side and the lower side of the inner rubber portion; and the flexible steel plate assembly is fixedly mounted between the spring rubber vibration reduction pad assemblies. The rubber bearing of the present invention has a relatively large elastic deformation after being loaded and can effectively conduct vibration reduction and earthquake resistance during use.
