Tangshan bridge bearing manufacturers direct sales show you the characteristics of round rubber bearings

Tangshan bridge bearing manufacturer's direct sales show you the round rubber bearing:

The characteristics of the circular rubber bearing: it has sufficient longitudinal stiffness to bear the vertical load, and has good elasticity to meet the rotation of the beam end; The shear deformation is large to adapt to the horizontal displacement of the upper structure.

Features of circular rubber bearing: this product is located in bridge construction. Water and electricity engineering. Building anti-seismic equipment has been widely used. Compared with the original steel bearing, it has the advantages of simple structure, convenient installation, steel saving, low price, simple maintenance and convenient replacement. In addition, the building height of the product is low, which is conducive to bridge design and reduce costs; It has good isolation effect and can reduce the impact of live load and seismic force on buildings.

The rectangular rubber bearing has many advantages, but for the acceleration line bridge, the horizontal deviation of the bearing is too much, which poses a safety risk to driving. The selection of new materials and new concepts can more effectively solve the beneficial characteristics of the horizontal bending stiffness of rectangular rubber bearings, while still maintaining low compressive and vertical bending stiffness. For the developed new waterproof flat rubber bearing, through static function test and functional fatigue evaluation of simulated passenger train, it is confirmed that the expected effect can be achieved with the same size, which is convenient for accelerating the replacement of line reconstruction.

The low friction resistance between polytetrafluoroethylene plate and stainless steel plate, in addition to the longitudinal stiffness and elastic deformation of the general plate-type rubber bearing, can also bear the vertical load and adapt to the rotation of the beam end（ μ F ≤ 0.08) does not limit the horizontal displacement of the upper structure of the bridge. The span of the bridge is more than 30 meters. Simply-supported continuous slab bridges and multi-span continuous beam bridges can be used as movable bearings; Continuous beam roof propulsion. T beam transverse movement and large equipment movement can be used as rollers.
