Jiujiang pot type rubber bearing factory Jingtong Rubber provides pot type bearings

Jiujiang pot type rubber bearing factory Jingtong Rubber provides pot type bearings Pot type rubber bearings produced by our company mainly include: ordinary plate bearings, tetrafluoroethylene ethylene There are three kinds of products: plate bearing and spherical crown pot rubber bearing.
1. Ordinary pot type rubber bearing is composed of multi-layer thin steel plate It is vulcanized and bonded with multi-layer rubber sheets to form a common pot type rubber bearing product. The pot type rubber bearing has good elasticity to cope with the rotation of the beam end of the bridge; It also has greater shear deformation capacity to meet the horizontal displacement of the superstructure.
2. When a layer of 1.5mm-3mm thick polytetrafluoroethylene material is pasted on the surface of ordinary pot type rubber bearing, it can be made into polytetrafluoroethylene sliding pot type rubber bearing, which can make the beam end slide freely on the surface of the tetrafluoroethylene plate, and the horizontal displacement is not limited. It is especially suitable for bridges with medium and small loads and large displacement
3. Spherical crown round plate pot type rubber bearing: the spherical crown round plate pot type rubber bearing is an improved round pot type rubber bearing. The arrangement of interlayer rubber and steel plate is exactly the same as that of circular pot type rubber bearing, while the top surface of the bearing is made of pure rubber into a spherical surface
Applicable scope of pot type rubber bearing
1. Generally speaking, ordinary pot type rubber bearings are suitable for bridges with spans less than 30m and small displacement. Different plane shapes are suitable for different bridge span structures, and rectangular bearings are used for orthogonal bridges; Curved bridge, skew bridge and cylinder Circular bearings for pier bridges
2. Tetrafluoro basin type rubber bearing is suitable for large displacement bridges with long-span, multi span continuous, simply supported beam continuous slab and other structures. It can also be used as a sliding block in the pushing of continuous beam and the transverse movement of T-shaped beam. The application of rectangular and circular tetrafluoro basin type rubber bearings is not only the same as that of rectangular and circular ordinary basin type rubber bearings.
3. The spherical crown round plate pot type rubber bearing is suitable for 3% to 4% longitudinal and horizontal slopes, and the center of the contact surface between the beam and the bearing tends to the center of the round PTFE plate pot type rubber bearing.
