Rubber Bridge Expansion Joint
Rubber bridge expansion joint have a framework, bolted assembly segments, each 1m (other sizes can be made), and the junction with the deed mouth-groove. Internal stiffening plate to make such joint can withstand the load of various vehicles, with some vertical stiffness. Since rubber incompressibility, rubber plate specially shaped groove prevents telescopic joints swell up when compressed.
Normal Specifications Bridge Expansion Joint
30 Type 1000 × 230 × 35,45 Type 1000 × 250 × 45, 50 Type 1000 × 270 × 42,60 Type 1000 × 400 × 40 etc. When Rubber bridge expansion joint is installed, the bottom surface of the bolt holes and joints per meter are filling adhesive coated, waterproof good. This product is anti-aging, wear rubber processing, can withstand repeated loads of vehicles, long service life for selection when they build new bridge.
