パッキンで調整することもある。In the bridge track, however, sleepers are laid on the bridge girder as the roadbed. In this case, since the tack head or the lid plate is usually present on the upper flange of the bridge girder, packing is inserted between the sleeper and the upper surface of the bridge girder to make the laying height of the sleeper constant. In addition, in order to attach a cant to the track curve portion, the height of the sleepers on both tracks may be adjusted by packing according to the cant amount.

５’，５’で連結している。FIG. 4 is a perspective view of a conventional bridge sleeper. A packing (wood) 2'having a predetermined thickness is nailed to the back surface of both ends of the sleeper 3 ', and the sleeper with packing is attached to the upper flange of the bridge girder 1'. 11 'with a hook bolt (not shown),
Further, a silicon material (for example, L-shaped material) is provided between the sleepers 3 ', 3'.
They are connected by 5'and 5 '.

【発明が解決しようとする課題】レ−ルには種々の力が
作用し、枕木においては、レ−ルに作用する力を分散さ
せて道床に伝達することが要求される。Various forces act on the rail, and in the sleeper, it is required that the forces acting on the rail be dispersed and transmitted to the roadbed.

ところが大である。Therefore, in FIG. 4, the load, for example,
When a force F'which generates a swelling (a phenomenon in which the rail slides in the longitudinal direction) acts on the rail, the sleepers 3'and 3'are connected by a sill member 5'in addition to the rail. Therefore, this force is also distributed to the sleeper group 3 ′, ... By the struts 5 ′, and the power distributed to each sleeper is transmitted to the bridge girder via the fastening member between the sleeper and the bridge girder. Therefore, the connection between the sleepers by the silage also largely contributes to the load distribution through the sleepers.
【０００７】しかし、けい材による枕木間の連結作業は
容易ではなく、また、枕木の交換時、枕木とけい材との
間の分離作業が必要であり、枕木の交換作業にも支障と
なる。However, the connecting work between the sleepers by the tie member is not easy, and when the sleeper is replaced, the separating work between the sleeper and the sill member is required, which hinders the replacement work of the sleeper.
【０００８】本発明の目的は、枕木間をけい材で連結す
