Railway fish plate (track joint splint) is commonly known as road splint, which serves as a connection at the track joint. Divided into light rail, heavy rail and super heavy rail. Fish plate is a kind of connection fastener used for connection between track and track. The use of fishplate rail has lower requirements than steel rail welding technology, and the installation is simple and quick. The fish plate is used in conjunction with fish bolts. The middle of them is provided with a screw hole, and along the upper and lower sides of the horizontal axis of the screw hole, an upper working surface contacting the lower part of the rail head and a lower working surface contacting the upper part of the rail bottom are provided. The rear part of the surface extends upward to form a transition section higher than the rail surface, and the transition section forms a bridge arch with a middle height and low ends along the length of the fishplate. The bridge-shaped has a simple structure, 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.

Light railway fish plate is also known as road splint, and heavy fish plate is also known as hoisting rail diagonal joint splint. The insulating fishplates are all made of insulating materials. Insulating plate is a new type of track material made of high-strength composite material. It is corrosion-resistant, anti-rust, anti-ultraviolet, non-conductive, and non-magnetic. It is a thermosetting material and cannot be processed twice, so it is not afraid of theft.

The railway fish plate model can be divided into 8kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg, 38kg, 43kg, 50kg, 60kg, 75kg according to the rail. There are 8KG, 9KG, 12KG, 15KG, 18KG, 22KG, 24KG, 30KG for insulated light fishplates. Insulated light plate is also known as road splint. Insulated heavy rail joint has 38KG, 43KG, 50KG, 60KG, QU70, QU80, QU100, QU120, also known as lifting rail diagonal joint splint.
