Rail fish plate can be classified into different types, common fish plate, glued insulated fish plate, compromised joint bar, insulated splice bar, bulge rail joint, angled rail joint. There are also different standards rail joint such as GB, BS, DIN, UIC, South Africa, American Rail Joint, suiting for different railways in various countries and areas.
Types of Railway Fishplate
Normal fish plate
The normal fish plate is the most common type, which is widely used in various kinds of rails. It is ordinarily made of medium carbon steel and high carbon steel. And there are two types of normal fish plate, four holes normal fish plates and six holes normal fish plates. The fish plate is used in conjunction with the fish bolt. The fish bolt penetrates through the elliptical hole, and the protrusion at the end of the bolt coincides with the elliptical hole, playing the role of fastening. The normal fish plate has the simplest structure among all kinds of them, which widely be applied in the railway tracks.
Compromise fish plate
Compromise fish plates are used to connect two different rail tracks, which have two separate sections, one is installed on the outside of the rails, and another is installed on the inside of the rails. There are upper working and lower working surfaces in contact with the rail along the horizontal axis. And the back of the upper working surface extends upwards, forming a transition section above the rail surface, which forms a bridge arch shape along the direction of the fish plate. Compromise fish plates are completely different in shape from the other two kinds of fish plates. Most of the compromise fish plates are customized, they are mainly used for some railway sections with special designs and requirements such as the railway turnout.
Joggled fish plate
Joggled fish plate is another type of fish plate, that has the same function as the normal fish plate. It can reduce the impact of wheels on rail joints, increase the continuity of longitudinal deformation of rail joints, and improve the flatness of trains passing through. The joggled fish plate is different in shape from a normal fish plate. it is a special forged fish plate that includes a fish plate and a bulge section in the middle. The joggled fish plate can effectively clamp and repair the welded steel rail, allowing the train to pass through the railway track safely. It has the characteristics of following rail deformation, a wide range of applications, convenient maintenance, durability, simple installation, and excellent fatigue resistance.
