Description

Rail fastening device for bridges {RAIL FASTENING APPARATUS FOR BRIDGE}

The present invention relates to a rail fastening device, and more particularly, to a rail fastening device for a bridge that can be used in the bridge and can be easily made the fastening process of the track rail and the sleeper.

In general, the track is formed by laying a bed, a sleeper, a rail, etc. on the roadbed, the sleeper and the rail or a direct connection fastening device and the rail together is called a guide.

The phases are divided into gravel phases and concrete phases, and the concrete phases are divided into sleeper embedded concrete phases, direct-type concrete phases, and floating slab phases.

In addition, direct-concrete concrete statues are divided into on-site direct-concrete concrete statues in which concrete is poured at the site to form the image, and factory-fabricated slab shapes that are assembled at the site after being manufactured at the factory.

When a train runs on a rail formed on such a figure, vibrations are induced, and the vibrations are propagated through the sleepers and the statues, thereby causing various vibration-related problems.

In the case of a track in which a sleeper is formed, when a repetitive load is applied to the rail between the sleepers, the rail is bent at the site and the contact between the wheels and the rails of the train is not constant and wear between the wheels and the rails is greatly increased. This wear can cause additional noise and vibration. And such wear and vibration will cause a great damage to the track.

In order to solve this problem, a method of alleviating the transmission of vibration by installing an elastic body such as a dustproof rubber between a rail and a sleeper or a bed is used.

Korean Patent Laid-Open Publication No. 10-2011-0080824 discloses a railway rail fastening device and a fastening method for concrete islands using bolts and wire springs, but the structure is complicated and the number of parts is high, which leads to high risk of damage and maintenance. The disadvantage is the increased cost. Moreover, there is a problem that the work time increases because four fixing bolts must be used for rail fastening.

Recently, the center portion is extended to the bottom of the rail, and when it is pulled outward, the rail can be replaced because it falls off the rail, and when fastening, a rail fastening device is disclosed that can achieve two-stage elasticity by touching two points. However, there has been a problem of not sufficiently removing the noise generated when the vehicle runs on the rails, and the vibration of the tie plate is caused by frequent vibrations, which causes the deformation of the rails, thereby degrading safety.

In order to solve the problems of the prior art, there is still a need for the development of a rail fastening device of an improved form that can easily prevent the vibration and noise while the rail fastening process is simple, especially in bridges using steel sleepers The development of this suitable rail fastening device is required.

In order to solve the above problems, the present invention has been made to solve the above-mentioned problems, and one embodiment of the present invention is a rail fastening device, which is simple and easy to fasten a track rail and a sleeper, ≪ / RTI >
