Brief introduction of bridge rubber bearings
Hengshui Jianfeng bridge laminated rubber bearing is in accordance with the standards of the Ministry of
communications JT/2004 production and acceptance of, it is made of multi-layer rubber sheets and thin
steel plates by adhesive and curing process, and designed for bridge and building construction - under
pre-cast concrete beams, steel beam supports and other support points - as local load carrying
components.It has enough vertical stiffness, the upper structure can force reliably transfer to the pier.


Characteristics of bridge 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.

Main function of bridge 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.

Jianfeng Elastomeric Bearing Assemblies are custom molded using neoprene or natural rubber and are categorized into three basic designs:
1.Steel Laminated Elastomeric Bearings
2.PTFE Sliding Elastomeric Bearings
3.PR/SR Plain Elastomeric Pad Bearing and Strip

1.Steel Laminated Elastomeric Bearings
The most commonly used bearings in bridges,steel laminated elastomeric bearings, are preferred due to
their versatility and lack of required maintenance.

2.PTFE Sliding Elastomeric Bearings
PTFE/Steel Reinforced Elastomeric Slide Bearing Assembly Laminated elastomeric bearings with PTFE
sheet bonded on the elastomer:a virgin PTFE layer is bonded to the elastomer to reduce the friction 
coefficient with the stainless steel welded to the top steel plate. 
3.PR/SR Plain Elastomeric Pad Bearing and Strip
Plain elastomeric pads are non-reinforced elastomeric pads or strips which resist low vertical load and allow
small movements.The simplest type of bearing, they are readily available and easy to install.

Natural Rubber : applicable temperature -40° C~50° C. 
Neoprene Rubber: applicable temperature -25° C~60° C.
Normally, The rubber material for elastomeric bearings are requested to used in different areas,some times
in different projects. Please name the rubber material when contact us.


Preparation of rubber compound according to specification required 
1. Preparation of steel plates 
2. Application of bonding agent to steel plates 
3. Assembly of compound and plates 
4. Compression moulding 
5. Performance Test 
6. Ready for installation
