Hengbeiao Bridge Expansion Joint

The bridge expansion joint is an expansion device for bridges, which solves the shortcomings of low service life, complex maintenance and high cost caused by the prior art. The technical scheme adopted is that the structure includes an elastic expansion mechanism set at the gap between two adjacent bridge beams, and a supporting auxiliary positioning device, The elastic expansion mechanism is made of organ plate made of austenitic stainless steel cold-rolled plate. The beneficial effect of the invention is that the elastic expansion mechanism uses austenitic stainless steel to achieve good acid and alkali resistance, drainage and workability, and greatly enhances the fatigue resistance by virtue of the structure of the organ board 。
