What Is The Connector Between Rails And Sleepers Called

The connector between rails and sleepers is called a spike.

Railway spikes are the basic components that connect rails and sleepers. They are used to fix rails and ensure the safety of vehicles while traveling on the railway.

Railway spikes are usually made of steel or other metal materials and have various shapes, but common spikes mainly include "V"-shaped spikes, conical spikes, buckle spikes and wire clamp spikes.

Characteristics of different types of spikes

(1). V-shaped spikes: V-shaped spikes are also called "crotch spikes". The center of the upper end is protruding and shaped like a "V". This type of spike is the most commonly used nail, easy to use, and has a reliable fixing effect.

(2). Conical spikes: The upper part of the conical spike is inverted cone shape, which can fit with the connecting part of the rail to ensure firmness. Moreover, the conical spike has a higher nail head hardness and higher wear resistance.

(3). Buckle spike: Buckle spike is a new type of spike invented by Shanghai Railway Bureau. It is more convenient to use than traditional spikes and can be replaced faster. Unlike traditional spikes, buckle spikes connect the rails through a U-shaped clip and use a nail-free connection, which greatly improves the strength.

(4). Wire clip spike: Wire clip spike, also known as "elastic buckle" spike, is a new type of spike designed with elastic steel wire and steel rod, which is more solid and can adapt to deformation and expansion at different temperatures.

When using any type of spike to connect the rails and sleepers, it must be ensured that the spikes can fully penetrate and penetrate the sleepers. Therefore, the installation of spikes must be carried out according to the specified depth and angle. In order to prevent the spikes from loosening, special washers or "thin plate" clamps must be used for installation.

Maintenance and replacement of spikes

The place where the spikes connect the railway and the sleepers needs regular maintenance and care. If the spikes are rusted or corroded, they need to be replaced with new ones. Timely maintenance and replacement can ensure the firmness of the spikes and the safety of the railway.

Spiks are important components connecting the railway tracks and sleepers. They have different types and characteristics, and the appropriate type can be selected according to the actual situation. Spikes play an important role in the construction, maintenance and upkeep of railways.
