Description

A fishplate is a flat piece of metal joining one rail or beam to another. The beam joints can be strengthened by iron fishplates. A fishplate is a metal or wooden plate that is bolted to the sides of the ends of two rails or beams, to join them. A fishplate is a flat piece of metal joining one rail or beam to another.

Compromise Fish Plates

With screw holes in the middle, upper and lower sides along the horizontal axis of the screw holes are provided with upper working surfaces that are in contact with the lower part of the rail head, and a lower part that is in contact with the upper part of the rail bottom. In the working face, the rear part of the upper working face extends upward to form a transition section higher than the rail surface, and the transition section forms a bridge arch shape with a middle height and low ends along the length direction of the fishplate. The bridge-shaped rail joint bar has a simple structure, which can reduce the impact of wheels on the rail joint, increase the continuity of the longitudinal deformation of the rail at the joint, and improve the smoothness of the train when passing through.
