DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The level crossing floor plate material according to the present invention will be further described below based on embodiments shown in the drawings. FIG. 1 is a side sectional view of one embodiment of the level crossing floor plate material according to the present invention, FIG. 2 is a front view thereof, FIG. 3 is a plan view thereof, and FIG. FIG. 5, which is a side sectional view of another embodiment, is a perspective view of a level crossing on which the level crossing flooring material shown in FIG. 1 is installed. In the drawing, 1 is a JIS spring type A type with a thickness of 25 to 50 mm, a pattern groove 1a for anti-slip on the top surface, and a bolt hole 1b through which a coach screw (to be described later) is inserted through the top and bottom. It is a rubber material with excellent weather resistance and abrasion resistance, with a hardness of 30 to 90 on a hardness tester. Not limited to those set parallel to the grid,
Various patterns such as a mesh shape and a ring shape can be used. In addition, the thickness of this rubber material 1 is 25
The reason for limiting the thickness to ~50mm is that if the thickness is less than 25mm, it will be too thin and have little tolerance for wear and will not be able to provide sufficient elasticity.
This is because if it exceeds mm, it becomes expensive, increases weight, and deteriorates processability and workability, which is not preferable. In addition, the hardness of the rubber material 1 was limited to 30 to 90 using a JIS spring type A hardness tester because if it is less than 30, it will be too soft and will be deformed by the force received from a car crossing the level crossing, which will be explained later. If it exceeds 90, it will be too hard and have poor elasticity, making it difficult for snow and ice to peel off from the surface and making it brittle, making it difficult to resist impact from the spikes of spiked tires. This is because the hardness cannot be absorbed and the phenomenon of chipping and cutting of the rubber occurs, which is undesirable.In particular, a hardness in the range of 50 to 60 is preferable because it has a good balance of elasticity and abrasion resistance. Considering the change in hardness of
It is preferable that the scale be designed to be 10 scales or less. Reference numeral 2 denotes a base material made of wood that is bonded to the lower surface of the rubber material 1 with an adhesive 3 and/or a coach screw 4. This is because out of many materials such as rubber, it is the cheapest material for railroad crossing decking, is light in weight, comes in a wide variety of sizes, and has excellent workability, so construction can be completed in a short period of time. Reference numeral 5 represents a coach screw for fixing the level crossing floorboard material according to the present invention to the railroad ties 6, and 4a and 5a represent washers. 7 is interposed between the rubber material 1 and the base material 2, and has a width of 1 to 4 times the thickness of the rubber material 1 and a height of 3 to 10 mm in the center of the railroad crossing floor plate material along the longitudinal direction. A steel plate 9 forms a void 8 to promote deformation of the rubber material 1 and facilitate peeling off a layer of snow or ice accumulated on the rubber material 1, and a steel plate 9 prevents contact between the steel plate 7 and the base material 2. In order to prevent the wood that is the base material 2 from being corroded by rainwater that has entered the void 8, the thickness of the material is 0.5 to 0.5.
A 1.5mm sealing sheet made of butyl rubber. Example 1 First, a material consisting of the composition shown in Table 1 was heated at 150°C
6mm wide x 12mm deep on the top surface by press vulcanization for 30 minutes
A rubber material 1 with a cross-sectional shape of 240 mm width x 30 mm thickness and a hardness of 55 on the JIS spring type A type hardness tester was obtained, and this rubber material 1 was laminated. The surface (lower surface) was oxidized with concentrated sulfuric acid to increase the adhesive strength with wood.

Next, a 5 mm thick steel plate 7 with a width of 1/4 of the width of the rubber material 1 is vulcanized and adhered to both sides of the lower surface of the rubber material 1, and a seal made of butyl rubber with a thickness of 1 mm is placed on the base material 2. The rubber material 1 was bonded to the base material 2 using the coach screw 4 used in Example 1 to complete a railroad crossing floor board material. At the railroad crossing site, the level crossing floor board material having the above structure is attached to a sleeper using a coach screw 5 with a diameter of 14 mm and a length of 240 mm, so that the head is depressed about 10 mm from the top surface of the rubber material 1 in the same way as the coach screw 4. It was screwed into sleeper 6 and fixed. Note that the hole through which the coach screw 5 is passed may be formed in advance when creating the level crossing flooring material, but it may be formed at an appropriate position according to the sleepers 6 at the site where the level crossing flooring material is to be laid. It may be perforated.

The level crossing floorboard material according to the present invention having the structure as detailed above has various advantages as listed below when used by being fixed on sleepers at a level crossing.
The contribution it makes to the field of transportation, especially in cold regions, is extremely significant. The upper layer is made of elastic rubber material, and pattern grooves are provided on the upper surface of the rubber material, so the upper surface deforms greatly when a car passes by, absorbing the impact from the spikes of spiked tires. Since the material has a certain hardness, chipping and cutting phenomena do not occur, and the wear resistance against spiked tires is higher than that of commonly used materials such as wood, concrete, steel plates, and plastics. /5 to 1/10, 1/2 to 1/3 of concrete, 2/3 to 1/2 of steel plate, and 1/2 to 1/3 of plastic, and can be laid without needing to be replaced for a long time. You can significantly reduce expenses such as expenses. The upper part is made of rubber material and has elasticity, so
When installed along the rails at a level crossing, not only is it difficult for snow and ice to adhere to the rails, but even if it does adhere, the rubber material is compressed and deformed by vehicles passing through the level crossing, and then the rubber material is deformed due to its restoring force. Since the snow and ice that sticks to the surface are removed by being flicked off, there is no need to perform any special maintenance and there is no need to worry about accidents caused by snow or ice. Since it is mainly made of rubber and wood, it is easy to manufacture and has excellent workability, making it easy to obtain level crossing sills of sizes suitable for various types of level crossings, reducing construction costs and shortening the construction period. can. The base material is wood that is cheap and easy to obtain.
It is difficult to deform and easy to store. It has excellent cushioning properties, so it does not damage sleepers or rails, making it highly practical.
