China Supplied Bridge Elastomeric Bearings for Phillipine

Model NO.: Dimension 100-1000mm Usage: Beam Bridge Material: Neoprene Color: Black Certificate: ISO9000 Trademark: JianFeng Specification: As Drawing Requests HS Code: 5522233 Certification: GB Structure: Laminated Rubber Bearing Activity: Fixed Bearing Shape: Rectangle and Circular Rubber Material: Cr and Nr and EPDM Transport Package: in Pallets or Wooden Cases Origin: Hebei, China I Description of Elastomeric Bridge Bearing

Elastomeric bearings shall be composed of multiple laminates of elastomeric material separated by steel reinforcing. Bearings have steel plates as the reinforcement shall be cast as a unit in a mold under pressure and heat and the steel plates separating the elastomeric layers shall be completely bonded by vulcanization to the elastomeric material on all surfaces. An external load bearing steel plate(s) shall be factory vulcanized to the elastomeric bearings during the primary molding process.

II Characteristics of laminated rubber bearings 

1.Good flexibility, in order to adapt to the rotation of beam end. 2.It has a larger shear deformation capacity, to meet the horizontal displacement of superstructure. 3.Laminated rubber bearing not only has excellent technical performance, but also has the advantages of simple structure, low cost, no maintenance, easy replacement, vibration isolation, low building height. So it is very popular in the bridge area, and be widely used.

III Classification and representation methods of bridge bearings

(1) Classification as shapes of bridge bearings  a.Rectangular bridge elastomeric bearings  b.Circular bridge elastomeric bearings (2) Classification as applicable temperature of adhesive varieties of bridge bearings  a.Neoprene bearing(applicable temperature -20~50°C)  b.NR bearing (applicable temperature --40~80°C ) (3) Classification as structure style of neoprene bearing a.General plate type neoprener bearing b.PTFE sliding plate type neoprene bearing.

IV Main function of laminated rubber bearings

The superstructure reaction reliably transfers to the piers, and also can complete  the deformation (horizontal displacement and angle of rotation) of the beam structure required. Laminated rubber bearing has enough stiffness in the vertical direction, and thus ensuring the bridge bearing to produce smaller deformation under the maximum vertical loads condition. Laminated rubber bearing has certain flexibility in the horizontal direction , can adapt to the beam and building body's horizontal displacement caused by the power, temperature, concrete shrinkage, creep and load effect; at the same time the laminated rubber bearing also adapt to the rotation of  beam ends.

 

V What does the surface of good elastomeric bearing pads look like 

1.The surface is smooth without any raised points.    2.Rubber material color- uniform and thick.    3.Rubber material could be kept color and brightness in air longer.
