Long rails as book rails have been researched and developed. 600m radius as a tracked track structure for railway tracks
It has been possible to lay a long rail for the curved parts up to, but for sharp curves with a radius of less than 600 m,
It has been considered impossible to lay long rails with conventional concrete sleepers due to the lack of lateral roadbed resistance. As a conventional buckling prevention device, a buckling prevention plate formed by welding a plate (a) shown in FIG. 11 to a fixing metal fitting (c) is arranged at the tip of a concrete sleeper (a),
A bolt (d) that is inserted through a concrete sleeper, or a plate (f), (ki) on a substantially U-shaped fitting (e) with fitting insertion holes at both ends shown in FIG. A buckling preventive plate formed by welding the above is installed by inserting a wedge (K) into the fitting insertion hole below the concrete sleeper (A), and the pillow shown in Figs. 13 and 14 Surrounding the sleeper end lower surface (K) and both side surfaces (SA) in a side plate (U) protruding downward from the lower end (K) of the rail end, and an enclosing plate (H) having horizontal flanges (SH) protruding to both upper sides ( Su)
It is known that an upper plate (a) that abuts the reinforcing plate (b) on the upper surface (so) of the sleeper end and a horizontal flange (s) are fastened together with bolts (tsu). (See, for example, Japanese Utility Model Publication Nos. 47-11845, 55-131301, and 62-35003).

向に座屈が働いても、締結力が保持できる。Since the present invention is configured as described above, it has the following effects. Since there is no need to penetrate the hole in the sleeper, and without removing the ballast below the sleeper, it can be installed simply by removing the ballast at the tip of the sleeper, which has better workability than below the sleeper. Since the lateral pressure resistance plate protrudes not to the lower side of the sleeper but to the side direction, it can be installed without deeply excavating the roadbed below the sleeper, the roadbed can be easily restored after installation, workability is good, and the existing track Can be easily attached to sleepers. Further, in the curved portion up to a radius of 600 m, the fastening force can be retained even if the buckling acts in the direction opposite to the mounting direction at a position where the buckling direction is not determined.
