JP 2005-163264 A

  By the way, the railcar track shown in the above publication has a problem that when the train derails, the derailed wheels greatly deviate from the rail track. In the railcar track described above, a safety guard is provided along the ladder sleeper. However, this safety guard is installed for the purpose of absorbing sound, and the rail track of the wheel due to insufficient strength. There was a problem that it was not possible to prevent deviations from.

  An object of the present invention is to provide a highly safe railcar track capable of preventing a derailed wheel from greatly deviating from a rail track, which is intended to solve the conventional problems. To do.

  In order to achieve the above object, in the problem solving means of the present invention, a rail support part provided along the length direction of the rails on the lower side of the pair of rails, and the rail on the rail support part A railcar track having fastening means for fixing, and corrugated steel having recesses and projections alternately formed along the rail support portion on the outer surface of the rail support portion. Corrugated steel is erected so as to protrude upward from the upper surface of the rail support portion.

Further, in the problem solving means of the present invention, the vertical sleepers respectively provided along the length direction of the rails below the pair of rails, the length of the rails so as to be along the direction orthogonal to the vertical sleepers. A railcar track having a ladder-type sleeper comprising a plurality of connecting members arranged at predetermined intervals with respect to the vertical direction and connecting the vertical sleepers to each other and fastening means for fixing the rails on the vertical sleepers. The corrugated steel in which concave and convex portions are alternately formed along the vertical sleeper is fixed to the outer surface of the vertical sleeper, and the corrugated steel protrudes upward from the upper surface of the vertical sleeper. Stand up like you do.
Moreover, in the problem-solving means of the present invention, the height of the corrugated steel is set to a height equivalent to or close to the top of the rail.

In the railcar track of the present invention, the concave and convex portions are alternately formed on the outer surface of the rail support portion along the rail support portion, and the wave is projected so as to protrude upward from the upper surface of the rail support portion. Since the steel is erected, when the train derails, the train wheels that fall from the rail are prevented from deviating from the train track by the corrugated steel. At that time, the wheel on one side of the train dropped from the rail falls into the gap between the inner surface of the corrugated steel projecting upward from the upper surface of the rail support portion and the rail, and the corrugated steel and the rail serve as a guide. Thus, the train vehicle is prevented from deviating from the track. Moreover, since the corrugated steel that is the outer guide is formed such that the concave portions and the convex portions are alternately formed along the rail support portion, the train wheel that has fallen from the rail moves in the length direction of the rail support portion. It is possible to gradually weaken the force of the train wheel to travel by intermittently colliding with a plurality of convex portions formed at intervals so as to follow, and deforming / destroying these convex portions. It is possible to stop safely without greatly deviating from the track. In addition, corrugated steel in which concave and convex portions are formed alternately can be deformed and expanded in the length direction of the rail support part, so it functions as an expansion joint at the joint part of the rail support part. In addition, the displacement of the rail support portion due to thermal expansion and contraction can be absorbed.
The railcar track of the present invention can also be applied to railcar tracks having ladder-type sleepers, thereby producing similar effects.
In addition, in railcar tracks with ladder-type sleepers, when vertical sleepers are buried in ballast, corrugated sheet steel in which recesses and protrusions are alternately formed may cause vertical sleepers to shift in the longitudinal direction. Therefore, the vertical sleepers can be held at a predetermined position.

  Further, in the railcar track of the present invention, the corrugated steel is set to have a height equal to or close to the top of the rail, so that the wave protruding upward from the upper surface of the rail support or the vertical sleepers. Using the inner wall of the steel plate and the rail as a guide, one wheel of the train that has fallen off the rail can be guided between these guides, and the train can be safely stopped without greatly deviating from the track. Become.

  Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is a plan view of a railcar track according to the present invention. FIG. 2 is a front sectional view of FIG. 1 viewed from the direction of arrow II. In these figures, reference numeral 1 denotes a ladder-type sleeper. is there. This ladder-type sleeper 1 is provided with vertical sleepers 2 provided below the pair of rails R so as to be along the length direction of the rails R (in the direction of arrows AB), and directions perpendicular to the vertical sleepers 2. It has the connection material 3 which is arrange | positioned along (arrow CD direction) and connects the vertical sleepers 2 mutually, and the fastening means 4 which fixes the rail R on the vertical sleepers 2, Comprising: Are arranged at a constant interval with respect to the length direction of the rail R (arrow AB direction).

  Corrugated steel 5 is fixed to each outer surface (indicated by reference numeral 2A) of the two vertical sleepers 2 constituting the ladder-type sleeper 1 so as to follow these vertical sleepers 2. In these corrugated steels 5, as shown in FIG. 3, concave portions 6 and convex portions 7 are alternately formed, and the convex portions 7 are arranged so as to be in contact with the outer surface 2 </ b> A of the vertical sleepers 2. Further, as shown in FIG. 2, each of the corrugated steels 5 is erected so as to protrude upward from the upper surface of the vertical sleepers 2 (indicated by reference numeral 2B). It is set to the same or approximate height position. And, by installing such corrugated steel 5, a gap as indicated by reference numeral 8 is formed between the inner wall surface 5A of the corrugated steel 5 projecting upward from the upper surface 2B of the vertical sleeper 2 and the vertical sleeper 2. When the train 10 derails as shown in FIGS. 4A and 4B, the wheel W dropped from the rail R travels while being guided by the rail R and the corrugated steel 5 in the gap 8. And will be slowed down. 4A is a front view when the train 10 derails to the left side of the rail R (arrow C side in the figure), and FIG. 4B is a front view of the train 10 to the right side of the rail R (arrow D side in the figure). It is a front view at the time of derailing.

  In the railcar track shown in the present embodiment as described above, the concave portions 6 and the convex portions 7 are alternately arranged along the vertical sleepers 2 on both outer side surfaces 2A of the vertical sleepers 2 of the ladder-type sleepers 1. Since the corrugated steel 5 is erected so that it is formed and protrudes upward from the upper surface 2B of the vertical sleepers 2, when the train 10 derails, the wheels W of the train 10 that have dropped from the rail R are Deviations from are prevented. That is, the wheel W on one side of the train 10 dropped from the rail R falls into the gap 8 between the inner wall surface 5A of the corrugated steel 5 protruding upward from the upper surface 2B of the vertical sleepers 2 and the rail R, and these corrugated steel 5 and the rail R serve as a guide to prevent the train 10 from deviating from the track.

  Further, the corrugated steel 5 serving as the outer guide is such that the concave portions 6 and the convex portions 7 are alternately formed along the vertical sleepers 2 of the ladder-type sleepers 1, so that the wheels of the train 10 that have fallen from the rail R W intermittently collides with a plurality of convex portions 7 formed at intervals so as to be along the length direction (arrow A-B direction) of the ladder-type sleeper 1, and deforms / destroys these convex portions 7. As a result, the force that the wheel W of the train 10 tends to travel can be gradually weakened, and the train 10 can be safely stopped without greatly deviating from the track.

  Moreover, since the corrugated steel 5 in which the concave portions 6 and the convex portions 7 are alternately formed can be deformed and expanded and contracted in the longitudinal direction of the vertical sleepers 2 (arrows AB direction), the joint of the vertical sleepers 2 It functions as an expansion joint (expansion joint) in the part and can absorb the displacement of the vertical sleepers 2 due to thermal expansion and contraction. Further, in the corrugated steel 5 in which the concave portions 6 and the convex portions 7 are alternately formed, even when the vertical sleepers 2 are buried in the ballast, the vertical sleepers 2 are arranged in the longitudinal direction (in the direction of arrows AB). ) Can be increased in resistance, and the vertical sleepers 2 can be held in a predetermined position.

  Further, in the railcar track shown in the present embodiment, the height of the corrugated steel 5 is set to be equal to or close to the top of the rail R. Using the inner wall surface 5A of the portion protruding upward from the upper surface 2B and the rail R as a guide, one wheel W of the train 10 dropped from the rail R can be reliably guided between these guides. It is possible to stop safely without greatly deviating from the track.
