Rubber bearing
Rubber bearings are used to support the weight of containers or equipment, and make it fixed in a certain position of the support, but also to withstand vibration and seismic loads in operation.
Plate rubber bearing is made of multi-layer rubber and at least two layers of the same thickness of thin steel plate inlaid, bonded, vulcanized, bridge products.
Plate rubber bearing is a commonly used support, and of course, it is also a relatively simple one. Plate rubber bearings are divided into rectangular and circular, of course, there are other shapes, but these two forms are common.
According to whether it can provide horizontal displacement, it is divided into polytetrafluoroethylene slide bearings and ordinary rubber bearings.
Plate rubber bearings are commonly code-named GYZ, GJZ, GYZF4, GJZF4.
Rectangular (circular) plate
(1) Performance: The product is made of multi-layer rubber sheet and thin steel sheet inlaid, vulcanized and pressed at a certain pressure, a certain temperature and a certain time. It has enough vertical stiffness to bear vertical load, can reliably transfer the reaction force of the beam and plate superstructure to the pier, and has good elasticity to adapt to the rotation of the beam end. And it has large shear deformation to meet the horizontal displacement of the upper beam structure.
(2) Features: This product has been widely used in bridge construction, hydropower projects, building seismic facilities, etc. Compared with the original steel support, it has the advantages of simple structure and convenient installation; Save steel, low price; Simple maintenance, easy replacement, etc.
Polytetrafluoroethylene slide bridge: referred to as tetrafluoroethylene slide bridge bearing, the product is made of a layer of 2-3mm thick polytetrafluoroethylene plate bonded on the ordinary plate rubber bearing.
Rubber bearing is a common rubber bearing product made of multi-layer thin steel plate and multi-layer rubber sheet vulcanized and bonded. The product has enough vertical stiffness to reliably transmit the reaction force of the upper structure of the support to the pier. The bearing has good elasticity to cope with the rotation of the bridge beam end. It has a large shear deformation ability and can meet the horizontal displacement of the superstructure. Plate rubber bearings are the most commonly used products for small and medium-sized highway Bridges, which are divided into ordinary plate rubber bearings and Teflon plate rubber bearings. Ordinary bridge supports are suitable for Bridges with spans less than 30m and small displacements. Different plane shapes are suitable for different bridge span structures, rectangular support orthogonal bridge; Curved bridge, inclined bridge and cylindrical pier bridge with round support. Teflon plate and rubber bearing are suitable for large displacement bridge structures such as long span, multi-span continuous plate and simple supported beam continuous plate. Continuous beam thrust and T-beam transverse movement can also be used in the slider. The application of rectangular and circular polytetrafluoroethylene plate rubber bearings is the same as that of rectangular and circular ordinary plate rubber bearings. Continuous beam thrust and T-beam transverse movement can also be used in the slider. The application of rectangular and circular polytetrafluoroethylene plate rubber bearings is the same as that of rectangular and circular ordinary plate rubber bearings.
