DescriptionRubber bridge expansion joint system utilizes the high elasticity of rubber to adapt to temperature changes and to make the bridge produce telescopic deformation. It is suitable for small and medium span bridges. Rubber bridge expansion joint system is designed to accommodate movement up to 330mm by shear deformation of the elastomer between the steel components. It incorporates steel angles designed to be bolted to the structural deck and a steel bridging plate system which spans the open joint gap.

FeathersRubber expansion joint comprises of a steel frame, unit assembly, bolt connection and installation, reliable and safe,smooth and comfortable for driving.
Our rubber expansion joint system is competitive at both domestic & abroad markets in the same industry by its convenient installation, stable running, waterproof, dust-proof, low noise, light weight, and low cost, etc.
The property of age-resistance and wear-resistance rubber enables the rubber expansion joint to withstand a repeated load of vehicles and a long service life.
ApplicationRubber bridge expansion joint is used in highway bridge decks, service ramps, multi- storey car parks and so on.
It is also applied to prevent the buildings or bridges from cracks due to climate change.
Construction process(1) Set out and cut rubber bridge expansion joint.
(2) Excavate and clean the Rubber Bridge Expansion Joint area.
(3) Drill holes to locate the anchor bolts.
(4) Place the rebar mat and mold.
(5) Pour bottom concrete layer.
(6) Install comb-shaped steel plate.
(7) Pour side concrete.
(8) Maintain the Rubber bridge expansion joint.
