How are steel rails fixed to sleepers?

We all know that the laying of rails cannot be separated from sleepers, but how are rails fixed on sleepers?  If you want to fix the rail on the sleeper, you need special parts, which we call fasteners.

As shown in the figure, where the rail is in contact with the sleeper, it is usually fixed with fasteners.  Engineering professional standards usually require fasteners to have sufficient strength, durability and certain elasticity, which can effectively maintain the reliable connection between the rail and sleeper for a long time, prevent the rail from moving, give full play to its buffering and shock absorption performance under dynamic action, and delay the accumulation of residual deformation of the rail.  In addition, the structure should be simple and easy to install and disassemble.  The small fastener seems insignificant, but it plays such an important role in the whole rail transit system! rail fastening systems

In addition, there are different kinds of fasteners. If the steel rail is connected to the wooden pillow, buckle plate fasteners and hybrid fasteners are required.  If the steel rail is connected with the concrete sleeper, elastic fastener is required.  As wooden sleepers have been largely eliminated and concrete sleepers are widely used now, the fastener also gradually adopts elastic strip type fastener. rail fastening systems

Due to the large weight and rigidity of the concrete pillow, the performance requirements of the concrete pillow fastener are also better than those of the wooden pillow fastener.  The main advantage of this kind of fastener is that the fastening pressure is sufficient. When the rail bends and rotates, it will not cause the rail to move longitudinally along the backing plate.  Moreover, appropriate elasticity is required, because the elasticity of concrete sleepers is much lower than that of wooden sleepers, and its elasticity is mainly provided by fasteners. rail fastening systems

In a word, although the fastener is small, it plays a very important role. Small fasteners show great wisdom.  If you choose rail fittings, please look for ZXsteelgroup. We will provide incomparable products and meticulous services to customers who need them.
