描述

Rubber gaskets are divided into two types according to their structure. The first type is made of multi-layer rubber sheets bonded, pressed and vulcanized. The second is made of multi-layer rubber sheet and reinforced steel plate bonded, pressed and vulcanized (also known as rubber bearing), which has enough vertical stiffness to bear vertical load, can reliably transmit the reaction force of the upper structure to the pier, has good elasticity to adapt to the rotation of the beam end, and has larger shear deformation to meet the water of the upper structure. Flat displacement. This product has been widely used in bridge construction, Hydropower Engineering and seismic facilities of buildings. Compared with the original steel bearings, it has the advantages of simple structure, convenient installation, steel saving, low price, simple maintenance, easy replacement, and low building height, which is beneficial to engineering design and cost reduction. The impact of live load and seismic force on buildings can be reduced. Rubber cushion blocks are widely used in railway, highway, construction, automobile, electronics, shipbuilding, petroleum, chemical industry, metallurgy, medicine, machinery, household appliances, agricultural machinery and other industries, almost involving all areas of production and life.
