Rubber expansion joint use high elasticity of rubber to adapt to temperature changes and make the bridge produces telescopic deformation.It is a kind of expansion joints coefficient of China using the longest products, is also one of the first expansion joint products, suitable for small and medium span Bridges.



Bridge Expansion Joint separate the structural elements above the basic, and set apart appropriate gap between both sides in order to ensure the structural elements on both sides of expansion joint free flexible in horizontal direction. The wide of sew is always 20_40mm. And then fill in thermal insulation materials.





Purpose: the highway bridge seismic isolation





Requirements of Bridge Elastomeric Expansion Joints

Items Rubber
Plate-type Combined type

Max horizontal frictional resistance of expansion and compression(KN/M)

<18
≤8
Max vertical deviation or deformation of expansion and compression -3-3 -2-2






Detailing requirements
(1) in parallel, perpendicular to the bridge axis of the two directions are free to flex
(2) reliable
(3) vehicles should be smooth, no sudden jump and noise
(4) waterproof and prevent debris into the obstruction
(5) installation, inspection, maintenance, eliminate dirt are easy to





Control points
1, the pre buried steel beam plate if the position is wrong or leakage is pre buried, is the anchorage method to reinforced fill.
2, after cutting to clean up the link anchor.
3, steel welding seam welding should be enough, to firmly.
4, the elevation of the surface of concrete to prevent the right, jump out of the vehicle.
5, the expansion joint anchorage firm, not loose, flexible and effective.
6, the curing time of concrete should be enough, not because of lack of maintenance time open to traffic.
