The bridge expansion joint device adopts integral hot-rolled special-shaped steel, which overcomes the characteristics of uneven straightness and collective size of extruded special-shaped steel. The comprehensive technical performance of the special-shaped bridge expansion joint device and technical indicators have reached or exceeded the advanced level of similar international products. The structural type and special-shaped steel rolling are both domestic firsts and will become the standard recommended product in the transportation industry. Bridge telescopic product features are low in building height and the height of domestic hot-rolled integrally formed special-shaped steel. It is simple in structure, easy to install, and has obvious reliability, comfort and durability. It can be used for various bridges with a bridge deck pavement thickness equal to or greater than that and a telescopic amount less than or equal to. It is not only convenient to replace the telescopic device of old bridges, but also can For use in new bridge construction
