What is the screw?

In the construction of railways, the tracks screw is used to ensure rails traces to the surface to which they are applied. In most cases, when a new rail system is built, the anchors for the track are made of concrete, unlike the wood from which they were traditionally made. In order to secure the track on concrete anchors, the track must be anchored to the concrete using the mounting bracket that holds the rail in place. Before the mounting bracket is applied to the rail, the mounting holder must be anchored to the concrete. This is done using a special screw.

Due to the amount of weight that the trace of the rail system must carry at the moment, the system must be the strongest as possible to avoid any possibility of moving. As a result, most mounting brackets, as well as track screws, are made of hardened steel. The steel is treated to prevent it from becoming susceptible to rust. These mounting systems that use tracks bolts are mounted and anchoredy directly to the anchor for the track, regardless of whether the tracks are made of concrete, wood or any other material.

The trace screw itself consists of more than just a screw. The tracks bolts are usually three -part fastening elements consisting of a threaded screw, eye or nut and lock pads. The pad prevents shifting or release of the track screw through intensive vibrations caused by the passing train.

The

matrix is ​​located on the mounting holder, through the tap, where the screw will be threaded while the pad sits on the top of the eye. The mounting holder and eyes have contradictory teeth, which, when dealing with each other, prevent any slip in the fastening process. After applying the lock pad, the screw is centered above the eye and slid into the anchor by tracking in the mounting bracket. Once the lock pad connects the screw, the screw is then prevented by sliding or twisting the free.

when he is a barkB paths attached and secured by mounting holder to the anchor of the track, security pin or pin on the track holding the mounting holder is pulled down. It then puts pressure on the lower flange of the rail. This is the most common method for fixing the railway line to the set anchor for the railway system.
