Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail joint sleeper used at a rail joint.

[0002]

2. Description of the Related Art Conventionally, a wide sleeper has been used as a sleeper for a rail joint used at a rail joint.

[0003]

Recently, wood or P has been used.
It has become difficult to obtain wide sleepers made of C for rail joints, and they tend to be made of metal such as cast iron and steel.

In view of the above problems, it is an object of the present invention to provide a railroad joint sleeper made of metal, and to provide a short joint sleeper that can be used only for one rail joint.

[0005]

In order to solve the above-mentioned problems, the short sleeper for seams of the present invention is used for one rail seam and has a bottom opening so that ballast can be filled inside. A hollow box-shaped metal short sleeper body is provided, and connecting rods for positioning are extended from this short sleeper body to both sides in the rail length direction, and these connecting rods are connected to adjacent sleepers on both sides in the rail length direction. It is configured to be engageable, and at least one of the connecting rods can be adjusted in length.

[0006]

With the above structure, when the metal short sleeper main body is placed at the rail joint and the rail joint is fixed, the short sleeper main body is embedded in the track and the inside of the short sleeper main body is fixed. By filling the ballast with
Since the side plate of the short sleeper body acts as a lateral pressure resistance plate, it is possible to secure a required lateral resistance force to the rail joint portion. Therefore, even with a short sleeper structure applied to only one rail, which is not a normal sleeper extending over the rails, the lateral resistance of the rail joint can be sufficiently obtained, and the material cost can be reduced. Also, by engaging the connecting rods extending in the rail length direction with the adjacent sleepers on both sides in the rail length direction, it is possible to position the short sleepers and also secure the resistance force in the rail length direction. Also, since this connecting rod can be adjusted in the length direction, even if there is a slight deviation in the installation position of the adjacent sleepers,
It can absorb this and can be used conveniently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 10 denotes a metal short sleeper main body installed at a joint portion of the rail 11, and has a short rail width direction so that it can be applied only to the joint of one rail. The short sleeper main body 10 is formed in a hollow box-like shape with an open bottom, and is made of a metal material such as ductile cast iron. Further, the short sleeper main body 10 and the rail 11 are coupled to each other by, for example, a fixing bolt 13 attached to the short sleeper main body 10 with a holding metal fitting 12 arranged between the short sleeper main body 10 and the short sleeper main body via a hard insulator 14. It is performed by fixing to both 10 and the rail 11. Reference numeral 15 is a hard insulating plate interposed between the bottom of the rail 11 and the upper surface of the short sleeper body 10. Further, a plurality of spike-shaped projections 17 for generating lateral resistance are provided on the lower edge of the side plate 16 around the short sleeper body 10 so as to project downward.

Further, from the upper plate 18 of the short sleeper main body 10, connecting rods 20 and 21 for engaging and positioning the adjacent sleepers 19 on both sides in the length direction of the rail 11 are extended, and the respective connecting rods are connected. The locking claws 22 at the tips of 20, 21 engage with the adjacent sleepers 19 so that the short sleeper body 10 can be positioned. Further, one of the connecting rods 20 is configured to have a lap bolt joint structure for adjustment, and the connecting rod 20 divided into two is fixed by the joint bolts 23 so that the connecting rods 20 can expand and contract. The positioning of the short sleeper body 10 can be adjusted. This adjusting lap bolt joint structure may be provided on the other connecting rod 21.

In such a structure, the short sleeper main body 10 is installed at the joint portion of the rail 11, and the joint bolt 23 of the connecting rod 20 is adjusted so that the locking claws 22 of the connecting rods 20 and 21 are adjusted.
Are engaged with the adjacent sleepers 19 to position the short sleeper body 10 in the rail length direction, and further, the holding metal fitting 1 arranged between the short sleeper body 10 and the rail 11
2 is fixed to both the short sleeper body 10 and the rail 11 via a hard insulator 14 by a fixing bolt 13 attached to the short sleeper body 10. Then, as shown in FIG. 2, the short sleeper main body 10 is filled with the ballast 24 to form a ballast layer also inside the short sleeper main body 10. As a result, the side plate 16 acts as a lateral resistance plate, and a required lateral resistance force to the rail joint portion can be secured. Therefore, even with a short sleeper structure applied to only one rail, which is not an ordinary sleeper extending over the rails, it is possible to obtain a sufficient lateral resistance at the rail joint. Furthermore, the plurality of spike-shaped projections 17 protruding downward from the lower edge of the side plate 16 of the short sleeper body 10 can supplement the lateral resistance force of the side plate 16 and can further increase the lateral resistance force.

[0010]

As described above, according to the present invention, since there is a tendency that the sleepers are made of cast iron or steel, the sleepers at the rail joints can be made of metal short sleepers applicable to one rail joint. Also as a structure, the short sleeper main body is configured as a hollow box shape whose bottom is opened and ballast can be filled inside,
By filling the interior with ballast, the side plate of the short sleeper body acts as a lateral resistance plate, so that the lateral resistance force to the rail joint portion can be secured and the material saving effect can be obtained.
