Description of the Related Art When it is necessary to enhance the track lateral lateral resistance and track longitudinal longitudinal resistance and to enhance safety against buckling and swelling, conventionally, measures to increase the track shoulder width and surplus are taken. Was taken. If this is not enough, buckling prevention plate 103 is attached to the end of sleeper 101 as a countermeasure against buckling, as shown in FIG. In addition, for wood sleepers, measures were sometimes taken to strengthen the fixation between the wood sleepers and the rails with an anti-creeper in order to prevent the rail from moving too far.

It was not possible to increase the vertical resistance of the bed. Moreover, the anti-creepers only played a role in strengthening the fixation between the wood sleepers and the rails, and could not enhance the track longitudinal resistance of the track.

The means to solve the problem was adopted. Used here
The roadbed resistance strengthening tool to be provided is provided with an overhanging member that projects in the horizontal and vertical directions of the railroad track and becomes a resistance when at least a part of the track is buried and the sleeper and the track move. Is characterized by.

らに向上するという顕著な効果を奏するのである。According to this roadbed resistance strengthening tool, the overhanging member further extends laterally and vertically from the sleeper, and at least a part of this portion is buried in the roadbed. The area can be increased, and the roadbed resistance can be strengthened both vertically and horizontally. Here, it is considered that the buckling of the track is a phenomenon caused by the longitudinal movement of the sleeper due to the rail expansion and thermal expansion. On the other hand, the roadbed resistance strengthening tool of the present invention strengthens the roadbed vertical resistance that has not been conventionally taken, thereby making it difficult for the track to buckle itself. Therefore, not only by simply increasing the resistance in the vertical and horizontal directions, but also by strengthening the vertical resistance force, the lateral resistance force is strengthened as compared with the conventional buckling prevention plate alone. In other words, the provision of vertical and horizontal overhangs is not only the addition of vertical overhang to horizontal overhang, but the vertical and horizontal overhang exerts a synergistic effect, and the buckling resistance is higher than the conventional one. It also has the remarkable effect of further improving.

する点で、一層優れている。[0008] This roadbed strengthening tool can be attached to an existing sleeper even from the end thereof and tightened and fixed to strengthen the roadbed resistance. It should be noted that it is easy to use mountain steel as the plate member. In addition, the plate-shaped member that extends in the vertical and horizontal directions may be formed only on one of the front side and the rear side with respect to the train traveling direction when the band-shaped metal fitting is attached to the sleeper. According to this configuration, it is convenient to construct a hole in the roadbed only on the front side or the rear side of the sleeper. However, the projected area in the vertical direction is the same as when the plate-shaped members are provided on both the front and rear sides, so that the longitudinal resistance force in the vertical direction does not decrease so much. Also, if you install the tool so that the plate-shaped member protrudes to the rear side at one end of the sleeper and the plate-shaped member protrudes to the front side at the other end of the sleeper, the projected area related to the lateral bed resistance will be the same. Can be said. Therefore, according to this structure, although the construction is simple, the effect of strengthening the resistance is sufficiently exerted, which is further excellent.
