非常に少なく且つ損傷の発生は全く検出されなかった。[Example 1] Hereinafter, the level crossing floor plate material according to the present invention will be further explained based on the example 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. Side sectional view of another embodiment, No. 5
This figure is a perspective view of a level crossing on which the level crossing flooring material shown in FIG. 1 is installed. In the drawings, reference numeral 1 has a thickness of 25 to 50 mm, and has a pattern groove 18 for preventing slipping on the top surface, and a bolt hole 1b through which a coach screw (to be described later) is inserted.
It is a rubber material with excellent weather resistance and abrasion resistance, with a hardness of 30 to 90 on the IS spring type A type hardness tester. It is not limited to those provided parallel to the longitudinal direction as in the example, but various patterns such as lattice, mesh, ring, etc. can be used. In addition, the thickness of this rubber material 1 is 2
The thickness is limited to 5 to 5'Omm because the thickness is 2511II1
If it is less than 1, the thickness is too thin and there is little tolerance for wear and it is not possible to impart sufficient elasticity.
If it exceeds 50 mm, it becomes expensive, heavy waste increases, and it is difficult to process. This is because workability deteriorates, which is undesirable. In addition, the hardness of the rubber material 1 was measured from 30 to 9 using a JIS spring type A type hardness tester.
The reason for limiting the value to 0 is that anything less than 30 is undesirable because it is too soft and deforms greatly due to the force received from cars crossing the level crossing, causing the joint with the base material described later to separate or damaging the bolt hole 1b. Moreover, if it exceeds 90, it is too hard and has poor elasticity, making it difficult for snow and ice to peel off from its surface, and making it brittle and unable to absorb the impact from the spikes of spiked tires, causing chipping and cutting of the rubber, which is undesirable. In particular, a hardness in the range of 50 to 60 is preferable because it provides a good balance of elasticity, wear resistance, etc. Furthermore, in consideration of changes in hardness at low temperatures, it is desirable to have a hardness in the temperature range of -15 to 30°C. It is preferable that the design is such that the change is 10 scales or less. Reference numeral 2 denotes a base material made of wood, which is joined to the lower surface of the rubber material 1 with an adhesive 3 and/or a coach screw 4. The base material 2 is made of wood, such as concrete, plastic, or iron. 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 range 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 floor plate 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 to form a gap with a width of 1 to 4 times the thickness of the rubber material 1 and a height of 3 to 10 mIn in the center of the railroad crossing floor plate material along the longitudinal direction. Part 8 is a steel plate that promotes the deformation of the rubber material 1 and makes it easier to peel off the layer of snow and ice that has accumulated on the rubber material 1, and 9 is a steel plate that prevents contact between the steel plate 7 and the base material 2 and creates a void. In order to prevent the wood, which is the base material 2, from being corroded by rainwater that has entered the part 8, it is laid on the top surface of the base material 2. It is made of butyl rubber or the like and has a thickness of 0.5 to 1.5111 m. This is a sticker sheet. Example 1 First, a material consisting of the composition shown in Table 1 was prepared at 150'Cx30
After press vulcanization for several minutes, the cross-sectional shape has a cross-sectional shape of 2A with a width of 6@ x depth of 12 m and a pitch of 30 mm for anti-slip on the upper surface.It has a width of 2401 + 11 + 1 x thickness of 30 mm and has a hardness of 55 on the JIS spring type A hardness tester. A rubber material 1 was obtained, and the bonding surface (lower surface) of this rubber material 1 was oxidized with concentrated sulfuric acid so as to increase the adhesive strength with wood. Below is the margin table 1 (unit weight part), followed by the width 2, which is conventionally used as floor board material for railroad crossings.
A 40 mm x 120 mm thick rod-shaped preservative treated Ezo pine was prepared as the base material 2. Then, as shown in FIGS. 1 and 2, the rubber material 1 is bonded onto the base material 2 using an epoxy adhesive 3 consisting of a main ingredient and a curing agent having the composition shown in Table 2. After the rubber material 3 has hardened, a coach screw 4 with a diameter of 12 mm and a length of 100 mm is screwed into the base material 2 through the bolt hole 1b in order to further complete the bond between the rubber material 1 and the base material 2. completed. Table 2 (Unit weight) Mixing ratio Base dicuring agent = 100. O: 100.0
(Jewelry ratio) Example 2 First, a rubber material 1 and a base material 2 were obtained in the same manner as in Example 1. Next, on both sides of the bottom surface of the rubber material 1,
A steel plate 7 having a width of 74 mm and a thickness of 5 mm was vulcanized and bonded, and a sealing sheet 9 made of butyl rubber with a thickness of 1111 mm was affixed on the base material 2, and the coach used in Example 1 was prepared. Rubber material 1 was joined to base material 2 using screws 4 to complete a level crossing floor plate material. The level crossing deck material having the above structure is attached to the sleeper at the railroad crossing site using a coach screw 5 with a diameter of 14 mm and a length of 240 m.Similar to the coach screw 4, it is attached to the sleeper 6 so that the head is depressed about 10 mm from the top surface of the rubber material 1. It was screwed in and fixed. Incidentally, 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. [Function] As a result of manufacturing the level crossing deck material having the structure shown in Examples 1 and 2 and installing and fixing it on a level crossing in a snowy area during the winter, almost no snow or ice was observed. In addition, there was no hindrance to the passage of cars or people, and the level crossing floorboard material itself suffered very little wear and no damage was detected.

When used by being fixed on railway sleepers at railroad crossings, it has various advantages as listed below, and its contribution to the field of transportation, especially in cold regions, is very 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 rubber material has a certain hardness, it does not cause chipping or cutting phenomena, and its wear resistance against spiked tires is higher than that of commonly used materials such as wood, concrete, WJ board, and plastic. 175~1/10 of
．． 172 to 1/3 of concrete. 273~1/ of steel plate
2. It is significantly superior to plastic at 172 to 1/3, and does not need to be replaced for a long period of time, resulting in significant savings in installation costs and other expenses. ■The upper part is made of rubber material and has elasticity, so when it is installed along the rail at a level crossing, it is difficult for snow and ice to adhere to it, and even if it does, the rubber material will be damaged by cars passing through the level crossing. Since the restoring force after being pressed and deformed repels and removes the snow and ice that has adhered to it, there is no need to perform any special maintenance and there is no need to worry about accidents due to the accumulation of snow or ice. ■Since the main components are 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 be realized. ■The paste material is wood, which is cheap and easily available, and 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.
