In general, railway rail fasteners are used to secure railway rails to rail sleepers for railway vehicles.

As a conventional railway rail fastening device, a base plate welded to a metal plate such as steel or steel to a metal plate such as steel or steel is used. However, the conventional base plate is in close contact with the lower surface of the metal rail and vibration and noise is very severe, damaging the rails, sleepers and bogies, causing noise pollution around the railroad and damage to the building. The fastening device for railway rails which has improved the conventional base plate is described in the design of Korean Utility Model Model No. 280105. In the design of the Korean Utility Model Utility Model No. 280105, a rail fixing plate having a shoulder on which rails are fastened so that the rails are fastened to the rail clips on both sides is coupled to the lower fixing frame fixed to the sleepers, and the lower fixing frames are both side walls. The both ends of the shoe extends to the sleeper fixing part, and a shoe is formed adjacent to both ends of the fixing plate, and both ends of the rail fixing plate are inserted into the shoe to reduce noise and vibration in the space between the rail fixing plate and the lower fixing frame. A vibration absorbing rail fixing assembly filled with a dustproof rubber layer is disclosed. However, the Korean Utility Model Registration No. 280105 devised a dust-proof rubber layer only on the bottom of the rail fixing plate, so that the lower surface of the steel rail and the rail fixing plate, which is also steel, were in direct contact with each other, so that the noise was very high and the absorption of vibration was minimal. there was.

Applicant developed the anti-vibration fastening device for railway rails to improve the shortcomings of the Korean Utility Model Utility Model No. 280105, was registered as Korea Utility Model Model No. 235976, and received the decision to maintain the technical evaluation result.
