Abstract

PURPOSE:To provide a crossing paving plate for constructing a simplified crossing, which is installed at a crossing where there is a relatively small density of traffic, for which existing sleepers are usable as they are, which can be mass-produced in a factory and which is easily constructed and maintained. CONSTITUTION:A preset flange-way is provided between right and left rails 12 in a track to place an inside-track paving plate 11 on a sleeper via a shock absorbing pad. An outside-track paving plate 17 is placed on a sleeper outside the track between the right and left rails via a shock absorbing pad. Both paving plates are connected together across the rail with a connector such as a fitting 19 arranged under the rail.

[0002]

2. Description of the Related Art In a conventional railroad crossing, as shown in FIG. 4, a guard rail 3 is fastened inside a main rail 2 fastened to a wooden sleeper 1 to secure a flange way 4.
A general method is to combine the wood 5, the L-shaped steel 6, and the concrete block 7 in the space of the remaining sleepers 1 and fix them to the sleepers 1 to construct the pavement for the road.

[0003]

With the widespread use of concrete sleepers as track structure members. How to construct road pavement on the concrete sleeper track has become a problem. On the other hand, the road pavement itself has been desired to be concrete from the standpoint of improving the price and quality by factory production and rationalizing the construction aspect.

In order to achieve the above-mentioned desire, a method of fastening a concrete pavement board to a concrete sleeper, a method of fitting and cushioning between an ordinary concrete sleeper and the bottom surface of the pavement board, or a pavement board within a gauge is used. Problems such as securing a flange way with the main line rail must be resolved.

In order to solve the above-mentioned problems, a special concrete sleeper for railroad crossings having bolt holes for fastening the pavement board and having an upper surface shape suitable for placing the pavement board is designed. However, in this case, the design of the concrete sleepers becomes complicated and expensive, and the maintenance management becomes complicated.
