Rail joints, also named railway fish plate, splice bar or rail joint bar, play a role in connecting rail joints. Fish plate is a kind of connection fastener used for connection between rail and rail, which is widely used in light rail, heavy rail and lifting rail.
Railway fish plate is used in conjunction with fishtail bolts, which is simple and quick to install. The rail joints are provided with screw holes in the middle, which are recessed inward along the horizontal axis of the screw holes to form a bridge structure. Such a design can reduce the impact of the wheels on the rail joint, increase the continuity of the longitudinal deformation of the rail at the joint, and improve the ride comfort and safety when the train passes.
