Rubber Bridge Expansion JointRubber 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.
characteristic:
Jianfeng Bridge Rubber Expansion Joint is the flexible transformation when using high elasticity to adapt the change of temperature. And it got good reputation of bridge engineering by its convenient installation, stable running, waterproof, dustproof, little noise, light weight, and low cost and other features.
Rubber expansion joint is made by a steel frame, unit assembly, bolt connection and installation, reliable and will not fall off, seam formation, driving smooth and comfortable.When this product is installed, the bottom bolt hole and joint per meter are filling and coating adhesive, water proofing property is good.This product ageing resistance, wear-resisting rubber processing and become, can withstand the repeated load of vehicles, long service life.
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 |
Bridge elastomeric expansion joints are designed to accept both horizontal and vertical loads due to traffic in accordance with the road engineering technical standards JTJ-88(1995)

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. |
Damage cause
| 1, the design of the Bridge Expansion Joint is not a week. |
| 2, the problems of expansion joint device |
| 3, after the pouring of expansion device of pressure filling material selection |
| 4, the construction is not reasonable |
| 5, continuous joint setting is not perfect |
