BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rail fastening system,

The present invention relates to a rail fastening device made of a synthetic resin material and integrated with a metal reinforcement material having improved economy, efficiency, durability and homogeneity.

Generally, the structure of the track is composed of a bedrock, a bed, a sleeper, a rail and a line structure. In the structure of such a track, a road bed is a group of gravels formed on a bedrock, and is generally classified into a general road, a secondary road, a concrete road, and the sleeper is laid beneath the rail to firmly position and hold the rail in place, Which are distributed over a wide range of road loads, are classified into wooden sleepers and concrete sleepers. The rails are fixed by a fastening device with screw spikes and spring clips to the concrete sleeper or concrete slabs. These fastening devices are basically equipped with elastic pads to reduce noise or vibration transmitted from the wheels to the rails during train operation .

Such a conventional technique is disclosed in Korean Patent Laid-Open Publication No. 10-2010-0126699 (hereinafter referred to as Patent Document 1).

Patent Document 1 includes a sleeper preformed with concrete, and on the free upper end portion of the sleeper, two stop portions separated from each other in the form of a hump-like ridge portion are formed. On each of the surfaces of the stop parts facing each other, there is a stop surface extending substantially parallel to each rail. In this way, the stop provides a lateral boundary of the receptacle extending therebetween in a direction across the rail, the flat base of the receiving port forming a substrate, and rails being laid on the substrate.

The support element is supported on the side surface of the guide plate on the side farther from the rail and mounted on the stopper. The guide plate supports the guide plate, And a tensioning clamp supported on the guide plate and having at least one spring arm for supporting the base of the rail and having a support surface associated with the guide plate and a support surface associated with the support, And a fastening bolt for fastening the tension clamp.

The rail fastening apparatus according to the above-described Patent Document 1 attaches and fixes the rail to the concrete sleepers through such a construction. Particularly, regarding the transverse force generated when the train travels on the rail, The guide plates disposed on both sides thereof are supported, and the guide plates can be laterally supported on the respective stop portions through the support elements.

However, the rail fastening apparatus of Patent Document 1 has a problem that it is difficult to manufacture a sleeper and it is necessary to spend an excessive amount of money because two fasteners spaced apart from each other in the form of a hump-like ridge are formed on the railroad tie itself.

The rail fastening device according to the related art is provided with a stopper formed in the railroad tie itself so as to stably support a transverse force generated when the train travels on the rail, The load is applied to the stop portion without being attenuated in the middle, so that the sleeper itself may be damaged. In the event that the sleeper itself is damaged, it is necessary to perform a complicated restoration operation .

In order to solve such a problem, Korean Patent Registration No. 10-1530965 (hereinafter referred to as Patent Document 2) has been proposed.

The above-mentioned Patent Document 2 includes a base plate for distributing a load transmitted from a lower side of a rail through a rail; An elastic pad elastically supporting the lower side of the base plate; A guide plate provided so as to be in close contact with a lower flange side surface of the rail to support lateral movement of the rail; A clamping clamp for pressing and supporting the lower flange of the rail from above; A fastening bolt through which the fastening clamp is pushed from the upper side so that the fastening clamp has a fastening force with respect to the lower flange of the rail and the lower part is buried in the concrete sleeping through the guide plate; And a bottom plate for mounting the elastic pad and the guide plate, wherein the elastic pad and the guide plate are mounted in tight contact with the upper surface of the sleeper, and the lower end surface of the guide plate is closely attached to the upper surface of the bottom plate, And an outer casing having a through hole through which a fastening bolt penetrating through the guide plate is continuously passed, the outer casing being provided with a support portion for supporting the guide plate in close contact with the left plate, The lateral load transmitted from the rail does not act as a bending load on the fastening bolt but is greatly canceled by the resistance due to frictional contact on the way and then acts as a shear load so as to suppress the damage of the fastening bolt, Can be extended.
