Description of Road Expansion Joint: Road 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 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 Expansion Joint is specifically designed to accommodate horizontal and skew movement and will also accommodate vertical movement due to rotation of up to 6mm.
Features of Road Expansion Joint: As one of the company’s main series of products, our 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.
Road Expansion Joint is the flexible transformation when using high elasticity to adapt the change of temperature. And our 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 Road Expansion Joint : Road Expansion Joint is used in Highway bridge decks, Service ramps, Multi- storey car parks and so on. Road Expansion Joint is used to prevent buildings or bridges appear some cracks because of climate change.
Construction programs of Road Expansion Joint: (1) Set out and cut Road Expansion Joint. (2) Excavate and clean the Road 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) Maintenance the Road Expansion Joint.
The whole requirements of road expansion joint.
1. Max horizontal frictional resistance of expansion and compression (KN/m)
2. Max vertical deviation or deformation of expansion and compression
The dimensional deviation of road expansion joints.
The hole distance of the screw L1deviation
Note: (Width Range) Positive deviation is used in the top of the expansion and contraction body, negative deviation is used in the bottom of the expansion and contraction body.
The appearance quality of road expansion joints and sealed belts.
