Description

FIELD OF THE INVENTION [0001] The present invention relates to a railway anti-vibration system using a steel beam resistant to torsion for rolling reduction. BACKGROUND OF THE INVENTION [0002]

[0001] The present invention relates to a railway anti-vibration system, and more particularly, to a railway anti-vibration system for a railway, which comprises a floating slab for a railway track and a concrete beam, And more particularly, to a vibration damping track system for a railway using a steel beam resistant to torsion for reduction.

In recent years, the importance of railway in transportation has become increasingly important due to stability and accuracy, and the speed of railway has been gradually increasing due to the introduction of high-speed railway. In addition, demand for urban railways and trains is increasing as part of the efforts to overcome traffic congestion in the city, and railway utilization and convenience are gradually increasing due to the opening of railway lines passing through urban areas and adjacent buildings.

However, due to increased noise and vibration due to the increase in the speed of the train, civil complaints are increasing, resulting in various problems such as deterioration of the usability of the structure and exceeding the environmental standard value related to noise and vibration.

In order to solve these problems, various methods such as application of a vibration pad have been attempted. Among them, a floating slab track is separated from the ground by a vibration pad or the like, .

The floating slab track is installed on the upper surface of the ground by making the concrete slab through which the train passes and is made of precast concrete slab. It is constructed to prevent noise and vibration by interposing a vibration pad, a spring or a damping member between the ground and the slab. do.

As shown in FIG. 1, the floating slab track is formed on the inner circumference (that is, the lower and both sides) of the foundation concrete 10, which is seated on the upper surface of the ground, The load of the vehicle transmitted through the track 40 is absorbed through the expansion and contraction of the vibration-proof mat by providing the dust-proof mat 20 on the upper part and the slab concrete 30 on the upper part thereof.

At this time, the dustproof mat 20 is designed to have appropriate thickness and rigidity for the purpose of controlling the load size of the vehicle and the deflection generation amount.

However, in such a conventional floating slab track, the load of the vehicle acts on both wheels equally to cause the same vertical deflection. However, if the vertical load is different in each wheel, that is, The amount of vertical deformation of the anti-vibration mat 20 is different.

In particular, in the curve section, the vertical load applied to both wheels is indispensable due to the centrifugal force, so that the vertical deflection amount of the anti-vibration mat varies on both sides, and the stability and the usability of the passenger are inconvenient do.

In addition, various problems such as lateral vibration and eccentric load due to wind load due to vehicle are caused due to a minute gap between the vehicle and the orbit in the straight line section.
