Waterproof expansion joint bridging device - consists of metal plate, covered by second plate with concertina-shaped expansion parts

摘要

The device incorporates a metal plate (6) to bridge the gap (1) in the joint. The metal plate is completely covered by another plate (20), which has expansion parts (21) extending in the longitudinal direction of the road. The surface of the second plate is flush with the road surface. The expansion parts are concertina-shaped. The second plate is removably connected to the edge beams (22,23). It is retained by continuous rails, the surface of which is flush with the road surface. The rails consist of abrasion-proof plastics. The edge beams have support plates for the displaceable metal plate, and a holder for the second plate. USE/ADVANTAGE - Waterproof expansion joint bridging device is for bridges and similar structures and is of simple construction and gives low noise when traffic drives over it.
