How do the Concrete Railway Sleeper Fix the Track?

We know that the laying of rails is inseparable from concrete railway sleeper, but how are the rails fixed on the sleepers? To fix the rails on the steel rail sleepers, special parts are needed, which are called fasteners in a professional way.

Zongxiang Steel Group is mainly engaged in light rail, heavy rail, hoisting rail, various external standard rails and other products. It also provides rail bending, rail drilling, rail cutting and other reprocessing services, switchers, rail presses, turnouts, The wholesale and retail of rail accessories such as concrete railway sleeper and fishplates, and the products have been exported to many around the world, and have been widely praised by customers at home and abroad.

This is a China rail manufacturer that has always adhered to strict management, honesty, scientific management and modern production technology, integrating production and sales, and providing customers with excellent rail products and perfect after-sales service. Today, let’s take a look at how the rails are fixed to the sleepers:

Where the rails are in contact with the sleepers, they are usually fixed with fasteners. Engineering professional standards usually require that the fasteners should have sufficient strength, durability and certain elasticity, which can effectively maintain the reliable connection between the rail and the sleeper for a long time, prevent the rail from moving relative to the sleeper, and can give full play to its cushioning under the action of power Shock absorption performance delays the accumulation of residual track deformation. In addition, the fastener should be simple in structure and easy to install and remove. The small fasteners seem inconspicuous, but they play such an important role in the entire rail transit system!

In addition, there are different types of fasteners. If rails are connected to sleepers, gusset fasteners and hybrid fasteners are required. If the rails are connected to the concrete railway sleeper, spring-type fasteners are required. As wooden sleepers have been eliminated in large numbers, concrete sleepers are now widely used, so the fasteners are gradually using spring-type fasteners. Due to the large weight and rigidity of concrete sleepers, the performance requirements of concrete sleeper fasteners are also greater than that of wooden sleeper fasteners. The main advantage of this kind of fastener is that the buckling force is sufficient. When the rail is bent and rotated, it will not cause the rail to move longitudinally along the backing plate, and it has appropriate elasticity. Because the elasticity of concrete sleepers is much worse than that of wooden sleepers, the elasticity is mainly provided by fasteners.

In short, although fasteners are small, they have great effects. Small fasteners see great wisdom. When choosing rail accessories, please look for zongxiang rail manufacturers, we will provide high-quality products and professional services to users in need.
