され、特に、枕木の更新作業が至難となる。However, in an overcrowded urban area, an elevated section, or a place surrounded by a soundproof wall, if the above-mentioned long sleepers of 6 to 9 m are integrally treated, the workability is inevitably reduced. Update work becomes extremely difficult.

Conventionally, in joining the sleeper pieces, as shown in FIG. 5, the ends of the sleeper pieces 1 ', 1' are processed into so-called half-cuts into stepped portions 11 ', 12' related to male and female.
A structure is used in which these steps are overlapped and the overlapped portion is fastened with bolts and nuts 2 ',... (Normally the number of bolts is four).

度を付与することが必要である。[0006] With regard to the dynamic state of the track, it can be approximately assumed that the vehicle load is distributed as an evenly distributed load on the track bed via the sleeper, and therefore, the bending moment acting on the center of the sleeper is the sleeper. Becomes larger as the length becomes longer, and the bending moment acting on the center connecting portion of the crossties of the track branching portions becomes larger because the overall length of the crossties is longer. Therefore, it is necessary to provide a large bending strength to the center connecting portion of the crossties of the branch portions.

The bending strength of the joint can be made to be comparable (70% or more) to the original bending strength of the synthetic sleeper. Therefore, even if a synthetic sleeper is used as the sleeper at the track branching portion, a sufficient bending strength can be imparted to the connection portion at the center of the sleeper, and the sleeper at the branching portion can be replaced with a synthetic sleeper from a conventional beechwood sleeper.

The efficiency increases as the other fibers wrap deep between the fiber ends E 1 and E 2 . Therefore, in terms of the efficiency of tension transmission, the taper angle θ
It is advantageous to reduce the diameter, but if it is too small, the rail is located above the bonding surface and the maximum bending moment immediately below the rail acts on the bonding surface, which is disadvantageous. The par angle θ is set based on these comparative considerations. Te - Pa - angle θ is preferably normally 20 0 ~5 0 (tanθ = 2 / 5~1 / 10).

In the synthetic sleeper connected according to the present invention, the tensile strength can be sufficiently supported by the long fibers even at the joint surface, and the reinforcing effect of the long fibers can be effectively exerted. It can be close enough to the bending strength. This can be confirmed from the comparison of the bending test results between the following examples and comparative examples.
