DESCRIPTONOFTHERUBBEREXPENSIONJOINT
Rubber Bridge Expansion Joint system comprises of 8 NO. Standard models designed to accommodate movement up to 330mm by shear deformation of the elastomer between the steel components. Each model of our Rubber Bridge Expansion Joint incorporates steel angles designed to be bolted to the structural deck and a steel bridging plate system which spans the open joint gap. The elastomer case is highly resistant to oils, solvent spillage and the trafficked surface includes an anti-skid pattern for safety having a rubber to rubber coefficient of static friction of 0.69. Each model of our Rubber Bridge Expansion Joint is specifically designed to accommodate horizontal and skew movement and will also accommodate vertical movement due to rotation of up to 6mm.
FEATURESOFTHERUBBEREXPENSIONJOINT
As one of the company's main series of products, our rubber expansion joint stands most competitive position in the domestic & abroad markets of same industry by its convenient installation, stable running, waterproof, dustproof, little noise, light weight, and low cost and other features. Rubber Bridge Expansion Joint is the flexible transformation when using high elasticity to adapt the change of temperature. And our Rubber Bridge Expansion Joint got good reputation of bridge engineering by its convenient installation, stable running, waterproof, dustproof, little noise, light weight, and low cost and other features.
APPLICATION OF RUBBEREXPENSIONJOINT
Rubber Bridge Expansion Joint is used in Highway bridge decks,Service ramps, Multi- storey car parks and so on. Rubber Bridge Expansion Joint is used to prevent buildings or bridges appear some cracks because of climate change.
