Rail Fish Plate
Function: A metal bar or plate bolted to the sides of two abutting rail ends to maintain alignment and transmit forces across the joint.
| Feature Category | Specification & Description |
|---|---|
| General Function | To connect two abutting rail ends, maintain alignment (vertical and horizontal), and transmit bending moments and shear forces across the joint. |
| Common Names | Joint Bar, Splice Bar, Angle Bar |
| Key Principle | Uses the strength of the fish plate and the clamping force of bolts to create a semi-rigid connection between rail ends. |
| Primary Material | Rolled or Forged Steel. Typically medium-carbon steel (e.g., 45Mn, 50# steel, ISO 5000/6000 series). Often heat-treated for wear resistance. |
| Common Types | • Standard Fish Plate: For general use on straight tracks and gentle curves. • Compromise Fish Plate: Designed to join two different rail sections (e.g., 50 kg/m to 60 kg/m). • Insulated Fish Plate (Jointed Insulated Block - JIB): Has nylon or composite insulation to electrically isolate track circuits for signaling. |
