Abstract

PURPOSE:To facilitate maintenance work and lower distributed pressure under crossties by fixing a collecting tie plate on the upper face of a plurality of crossties arranged mutually adjoined, and supporting and combining a rail. CONSTITUTION:A plurality of PC crossties of concrete on which a pair of recessed part in the rail 6 laying direction are provided crossing with the rail 6 are arranged. Projecting parts 9 underside a collecting tie plate are fitted into the recessed parts 8, and lateral pressure applied on the rail 6 is borne with them. The rail 6 is pinched with a pair of supporting parts 5 on the upper face of the collecting tie plate 2, positioned, and fixed from both sides with band clips 7. Further, reinforcing members 10 such as shape steel are fixed underside the PC crossties 1. Hereby, a plurality of crossties 1 are collected into one body, and hence broad bottom area can be obtained and distributed pressure under the crossties 1 can be lowered.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a rail fastening structure.

2. Description of the Related Art As a conventional rail fastening structure, a structure in which a tie plate or the like is used to fix a rail to concrete PC sleepers arranged at predetermined intervals is often used. Underneath the rails and sleepers, ballast or
It is hardened.

Problems to be Solved by the Invention However, such conventional devices have a problem in that maintenance of the ballast is time-consuming. Another problem is that the pressure distribution under the sleepers is high.

Therefore, the present invention aims to solve such problems.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a plurality of sleepers arranged adjacent to each other, a rail that is arranged over the upper surface of the plurality of sleepers, fixed to each sleeper, and a rail. and an assembly tie plate that can be supported and fastened.

Effect: According to this configuration, a plurality of sleepers are integrated into the tie plate for assembly, so a sleeper with a wide base area can be obtained.

This not only makes ballast maintenance easier, but also reduces the pressure distribution under the sleepers. Since a plurality of sleepers are integrated, it is possible to construct a sleeper with a wide base area by using conventional sleepers as is.

Embodiment In FIGS. 1 and 2, l is concrete P.
A plurality of C sleepers, for example three, are arranged adjacent to each other. An assembly tie plate 2 having a length spanning the three PC sleepers l is provided on the upper surface of these three PC sleepers l. That is, each PC sleeper l
An impregnated cushioning pad 3 is laid on the top surface of the PC sleeper l.
The tie plate 2 for assembling is fixed to the three PC sleepers with the impregnated pad 3 in between by bolts 4 screwed into the board.

A pair of recesses 8 in the same direction as the installation direction of the rail 6 are formed on the upper surface of the PC sleeper l at a distance in a direction orthogonal to the rail 6. Furthermore, a pair of protrusions 9 are formed on the lower surface of the assembly tie plate 2 and fit into the recesses 8, and the lateral pressure acting on the rail 6 can be received and stopped by these fittings. At the same time, it is possible to prevent the impregnated pad 3 from shifting laterally.

A pair of support parts 5 are formed on the upper surface of the assembly tie plate 2, and by sandwiching the rail 6 between these support parts 5,
This rail 6 is positioned. A band roll clip 7 is held on each support portion 5, and the rail 6 is fixed from both sides by this band roll clip 7.

1O is a reinforcing member, which is made of shaped steel, and is arranged in the direction in which the rail 6 is laid across the lower surface of the plurality of PC sleepers 1,
It is fixed to each PC sleeper l by fixing means such as bolts. As shown in FIG. 3, at the end of the PC sleeper 1,
A U-shaped anti-vibration rubber shoe 11 is provided to sandwich the plurality of PC sleepers l. Anti-vibration rubber・
A spring steel 12 is embedded inside the shoe 11. In FIG. 2, 13 is a ballast.

According to such a configuration, a plurality of PC sleepers 1 are integrated by the assembly tie plate 2, and a sleeper with a wide base area can be constructed. Therefore, there is an advantage that the pressure distribution under the sleeper can be lowered and maintenance work for the ballast H3 becomes easier.

Since a plurality of PC sleepers 1 are integrated, existing PC sleepers can be used as is. Reinforcement member l
It is also possible to expect the effect of integration by reinforcing with O. An impregnated pad 3 is provided between the rail 6 and the PC sleeper 1, and an anti-vibration rubber shoe 11 is provided at the end of the PC sleeper 1 to elastically support the PC sleeper 1. The effect will also be satisfactory.

FIG. 4 shows a tie plate assembly 2 according to another embodiment of the invention. In this example, the assembly tie plate 2 is formed into an H-shape by providing a hollow portion 14 in the portion of the tie plate that supports the rail, thereby reducing its weight.

Effects of the Invention As described above, according to the present invention, an assembly tie plate is provided which is placed over the upper surface of a plurality of sleepers arranged adjacent to each other and fixed to each sleeper, so that existing sleepers can be used as is. By doing this, you can obtain sleepers with a wide base area. Therefore, the pressure distribution under the sleepers can be lowered, and the ballast can be easily maintained.
