Model NO.: various Material: Natural Rubber Export Markets: Global Urgent Oder: Yes Transport Package: PP Woven Bag Origin: Hengshui, Hebei, China (Mainland) Usage: Bridge/Highway Model No.: Displacement 60-330mm Metarial: Rubber,Steel Plate Trademark: Jianfeng Specification: various specifications HS Code: 40169990 Rubber Bridge Expansion Joint
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.
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.
Purpose: the highway bridge seismic isolation
|(1) in parallel, perpendicular to the bridge axis of the two directions are free to flex|
|(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|
