Description :

　　Bridge rubber bearings

　　1. Product Introduction:

　　Bridge rubber bearings are made of multiple layers of rubber sheets and thin steel plates vulcanized and bonded together. They have sufficient vertical rigidity and can reliably transmit the reaction force of the upper structure to the pier and abutment; It has good elasticity to adapt to the rotation of the beam end, and has a large shear deformation ability to meet the horizontal displacement of the upper structure.

　　2. Usage:

　　By sticking a layer of polytetrafluoroethylene plate on the surface of the above-mentioned plate type rubber bearing, a polytetrafluoroethylene sliding plate type rubber bearing can be made. In addition to vertical rigidity and elastic deformation, it can withstand vertical loads and adapt to beam end rotation. Due to the low friction coefficient of the polytetrafluoroethylene plate, the beam end can slide freely on the surface of the polytetrafluoroethylene plate, and the horizontal displacement is not limited. It is particularly suitable for bridges with medium to small loads and large displacement.

　　Bridge rubber bearings not only have excellent technical performance, but also have the characteristics of simple structure, low price, easy replacement of buffering and isolation without maintenance, and low building height. Therefore, it is quite popular and widely used in the bridge industry.

　　3. Scope of application:

　　1. Ordinary bridge rubber bearings are suitable for bridges with spans less than 30 meters and small displacements Different planar shapes are suitable for different bridge span structures, and rectangular supports are used for orthogonal bridges; Circular bearings are used for curved bridges, skew bridges, and cylindrical pier bridges.

　　2. The PTFE plate bridge rubber bearings are suitable for large-span, multi span continuous, simply supported beam continuous plate and other structures with large displacement bridges. It can also be used as a slider in continuous beam pushing and T-shaped beam lateral movement. The application of rectangular and circular PTFE plate rubber bearings is similar to that of rectangular and circular ordinary plate rubber bearings.

　　It is made by embedding, bonding and pressing multiple layers of rubber sheets and thin steel plates. There is sufficient vertical stiffness to withstand vertical loads, which can effectively transmit the reaction force of the upper structure to the pier and abutment; Has good elasticity to adapt to the rotation of the beam end, and has significant shear deformation to meet the horizontal displacement of the upper structure.

　　Characteristics of GJZ rectangular GYZ circular plate rubber bearing:

　　This product has been widely used in bridge construction, hydropower engineering, and seismic facilities of buildings. Compared with the original steel bearings, it has a simple structure and easy installation; Save steel and keep prices low; The advantages of easy maintenance and replacement, as well as the low building height of this product, are beneficial for bridge design and cost reduction; It has a good seismic isolation effect, which can reduce the impact of live loads and seismic forces on buildings.
