Joint bar railroad, also known as railway fish plate, rail joint bar or splicing bar, is a metal bar that is bolted to the ends of two rails to connect them together to form a rail.
Two rail joints are usually used in pairs. One side of each rail joint bar is configured as the rail web side. Mechanical fasteners install the joint bar to the side of the web. The pair of keys in the web and the joint bar transmit the railroad load through the joint and greatly strengthen the rail joint assembly.
Joint Bar Railroad Features:
1. It should connect the rails so that they act as continuous beams with uniform surfaces and alignment.
2. Its anti-deflection ability should be as close as possible to the anti-deflection ability of the rail to which it is applied.
3. It should prevent vertical or lateral movement of the rail ends relative to each other, unless otherwise specified, it should allow the longitudinal movement required for expansion and contraction.
4. It should be as simple as possible and have as few parts as possible to be effective.
5. Each rail joint, insulating joint and compromise joint should have a reasonable design and the size of the rail suitable for its application.
6. In the worn rail area, a high clearance joint bar can be used to provide additional rim clearance.
