Haichen Supply Customized Seismic Isolation Rubber Bearings Plate Rubber Bearings Seismic Spherical Bearings Manufacturer

Description :

　　Plate rubber bearings are a type of bridge bearing product made by embedding, bonding, and vulcanizing multiple layers of natural rubber and thin steel plates. This type of rubber bearing has sufficient vertical stiffness to withstand vertical loads and can reliably transmit the pressure of the upper structure to the pier; Has good elasticity to adapt to the rotation of the beam end; There is significant shear deformation to meet the horizontal displacement of the upper structure.

　　Product Features:

　　It has the characteristics of simple structure, easy installation, steel saving, low price, easy maintenance, and easy replacement.

　　By sticking a layer of 1.5mm-3mm thick polytetrafluoroethylene plate on the surface of the plate support, a polytetrafluoroethylene sliding rubber support can be made. In addition to vertical stiffness 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 PTFE plate, and the horizontal displacement is not limited. It is particularly suitable for bridges with medium to small loads and large displacement.

　　Product division:

　　1、 Rectangular (circular) plate rubber bearing

　　（1） Performance: Sufficient vertical stiffness to withstand vertical loads, good elasticity to adapt to the rotation of beam ends; There is also significant shear deformation to meet the horizontal displacement of the upper structure.

　　（2） Features: This product has been widely used in bridge construction, hydropower engineering, and building seismic facilities. Compared with the original steel bearings, it has the advantages of simple structure, convenient installation, steel saving, low price, easy maintenance, and easy replacement. Moreover, the low building height of this product is 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.

　　2、 Tetrafluoroethylene sliding plate rubber support

　　（1） Features: This product is made by bonding a layer of 1.5-3mm thick polytetrafluoroethylene plate onto a regular plate rubber bearing. In addition to the vertical stiffness and elastic deformation of ordinary plate rubber bearings, which can withstand vertical loads and adapt to beam end rotation, the low friction coefficient (μ ≤ 0.03) between tetrafluoroethylene and the stainless steel plate at the bottom of the beam allows for unrestricted horizontal displacement of the upper structure of the bridge.

　　Product application scope:

　　Plate rubber bearings are commonly used products in small and medium-sized bridges on highways, which are divided into ordinary plate rubber bearings and PTFE plate rubber bearings. For ordinary bridge bearings, they are suitable for bridges with spans less than 30m 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

　　Tetrafluoroethylene plate rubber bearings are suitable for large displacement bridges with large-span, multi span continuous, simply supported beam continuous plate and other structures. 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 the same as that of rectangular and circular ordinary plate rubber bearings.
