Description of Spherical Bridge Bearings
It is composed by top plate, base plate, convex middle plate and two PTFE plates of different composition.
Opposite the top plate, it is a concave spherical in the base plate, and the PTFE plate between them. Beam
rotation through spherical surfaces and PTFE plate sliding; stainless steel plate on the top plate and another
PTFE plates on the intermediate steel plate performthe second sliding surface, realized beam stretching
displacement produced by temperature factors.
Spherical bearing: The Spherical bearing is a special structure bearing. It adopts a spherical structure and has rolling performance in multiple directions. Spherical bearings are mainly used to support long-span bridges or complex-shaped bridges. Because the spherical bearing can roll in multiple directions and adapt to different deformations of the bridge, it can effectively disperse the load and reduce the stress concentration on the bridge. In addition, spherical bearings can also improve the seismic performance of bridges. When an earthquake occurs, the rolling performance of the spherical bearing can absorb shock, disperse earthquake energy, protect the bridge structure, and improve the bridge's earthquake resistance.
Vertical load of Anti-aging Spherical Rubber Bridge Bearings:
One-way movable QZ Spherical Bridge bearing (DX): horizontal force in cross-bridge direction is 10% of the capacity of reaction force.
Fixed QZ Spherical bridge bearing (GD): the horizontal force is 10% of the reaction force.
1. The rotation angle of the support is divided into 0.01,0.05 and 0.02rad, which can be increased according to the requirement.
2. The vertical bearing capacity of 1000-100000KN is divided into 16 levels, and the bearing capacity of the bearing is 10%.
3. Coefficient of friction: Normal temperature type μ≤0.03; Hardy type μ≤0.05.
4. Displacement of bearing design:
a.bridge in axial direction: ±50,±100,±150mm
b.transverse direction of bridge: ±20mm
The design displacement can be changed according to the engineering requirements.
Packed in Wovenbag and pallet according to the customes' requirements.
Delivery: within 20 days after receiving the deposit.
