Description

  The present invention relates to a rail fixing jig, and more particularly, to a rail fixing jig for preventing expansion of a rail gauge due to a breakdown of a rail fastening device when a train is derailed.

  The two rails on which the wheels of the train run are supported by layers formed of gravel or crushed stone, so-called sleepers installed on the roadbed, and the load of the vehicle is distributed to the roadbed via these roadbeds. It is like that. A track structure in which rails are laid by such a method is called a roadbed track, and has been frequently used in the past.

  However, the above-mentioned roadbed track has many problems in that the track is broken and frequent maintenance management is required. Therefore, as shown in FIG. 17, as a new track structure, a packed bed F made of CA (Cement Asphalt) mortar or the like is formed on the upper surface of the roadbed R formed of concrete. A method of laying rails on the upper surface of the track slab S installed on the upper surface of the track has been developed. The track structure in which the rails are laid by such a method is called a slab track, and the slab track is adopted for the majority of recently established routes represented by the Shinkansen.

A plurality of rail fastening devices 100 are arranged at equal intervals on the upper surface of the track slab S in such a slab track. The rail fastening device 100 includes a plate-like bottom surface member 101 and a substantially quadrangular columnar holding portion 102 that protrudes upward from the top surface of the bottom surface member 101. Each of the rails R ₁ and R ₂ includes In addition to being supported by the upper portion of the bottom surface member 101, the holding portion 102 guides in a predetermined direction and prevents the rails R ₁ and R ₂ from being displaced in a direction perpendicular to the longitudinal direction. . The rails R ₁ and R ₂ are fixed in a pressed state by leaf springs or wire springs (both not shown) fastened by bolts. (For example, refer to Patent Document 1).

Even so, the distance between the rails R ₁ and R ₂ can be maintained in the initial state of installation.

Thus, long rails _R 1, a portion of the _{R 2} 2 two claw portions 46, 46 for locking is provided a rail _R 1, sleepers _S 1 of two adjacent _{of R 2} is supported, S a supporting portion 44 for fixing to _2, from the rail _R 1, _{R 2} and the rail _R 1, rail _R 1 a gap O formed between the track bed _{R 2} is laid B, _{R 2} in the horizontal direction X The first insertion member 41 and the second insertion member 42 to be inserted, and a locking piece 12 for locking a part of the rails R ₁ and R ₂ are provided, and are fixed to the first insertion member 41 and the second insertion member 42. Since the first fixing member 21 and the second fixing member 22 are provided, the first insertion member 41 and the second insertion member 42 are fixed to the two sleepers S ₁ and S ₂ adjacent to each other by the support portion 44. The two claw portions 4 of the support portion 44 in the first insertion member 41 and the second insertion member 42. , 46 as well as by rail R _1, R ₂ by the engaging piece 12 of the first fixing member 21 and the second fixing member 22 is locked, there when the rail fastening device C with the derailment of the train is damaged even, it is possible to maintain the gauge of the rails R _1, R ₂ placed in the original state, whereby, in organic ballast track, it is possible to prevent a serious accident rollover such train.
