Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubber plate, and more particularly to a rubber plate which is laid at a railroad crossing or the like and in which a belt-like pattern is repeatedly formed on a plate surface through which a vehicle passes.

[0002]

2. Description of the Related Art Conventionally, a plate made of wood, iron plate or concrete has been used as a plate laid on a railroad crossing or the like and through which a vehicle passes. Such a plate made of a rigid material has a drawback that loud noise is generated when the vehicle passes. For this reason, Tokuhei 7-305
The rubber plate proposed in Japanese Patent Publication No. 22 is being used for railroad crossings and the like. According to such a rubber plate, noise or the like when the vehicle passes through a railroad crossing or the like can be reduced as compared with a conventional plate formed of a rigid material.

In the rubber plate disclosed in the above publication, a plate surface through which a vehicle passes is smoother than a plate formed of a conventional rigid material, so that pedestrians and the like can easily slip. Therefore, as shown in FIG. 6 or 7, a circular or hexagonal pattern 102, 102,... Is formed over the entire surface of the rubber plate 100 to prevent slippage. The thickness of the patterns 102 formed on the rubber plate 100 shown in FIG. 6 or 7 is the same as that of the gaps 106 between the patterns 102 as shown in FIG. 8, which is a side view of the pattern 102 shown in FIG. It is difficult to close the gap 106 even when the pattern 102 is deformed by being pressed by the vehicle tire. The hole 104 shown in FIG. 6 is an insertion hole for inserting a bolt for fixing the rubber plate 100 to a sleeper or the like. After the rubber plate 100 is fixed to the sleeper or the like with the inserted bolt, a rubber stopper or the like is used. Is closed.

[0004]

As shown in FIG. 6 or FIG. 7, a circular or hexagonal pattern 102, 102,... Walking can be facilitated. However, circular or hexagonal patterns 102, 1
Because dust and rainwater such as sand easily accumulate in the gap between 02.
When it rains, the patterns 102, 102,.
Water accumulated in the gap between 02, 102,... May be repelled to pedestrians and the like. Also, patterns 102, 102
· · Even if a rubber plate is painted on the plate surface through which the vehicle passes by dust such as sand accumulated in the gap between the plates, the appearance of the plate is reduced in a short time. SUMMARY OF THE INVENTION It is an object of the present invention to provide a rubber plate that prevents the plate surface from slipping and that hardly accumulates dust and water on the plate surface.

[0005]

In order to solve the above-mentioned problem, the present inventors forcibly discharge water or the like accumulated between patterns by using deformation of a pattern when passing through a vehicle. As a result, the present inventors arrived at the present invention.
That is, according to the present invention, a belt-shaped pattern is repeatedly formed on a plate surface of a rubber plate that is laid on a railroad crossing and the like, and through which a vehicle passes. When partially deformed by pressing, a gap is formed in which at least a part of the deformed portion of the band-shaped pattern contacts and is partially closed,
And when the vehicle passes through the plate surface, due to the pressing of the vehicle tires, the closed portion of the gap due to the partial deformation of the belt-shaped pattern adjacent to each other moves as the vehicle advances,
The gap is extended in the traveling direction of the vehicle so that water and the like can be discharged from the exit of the gap, and the exit of the extended gap is opened in the traveling direction of the vehicle. On a rubber plate.

In the present invention having such a configuration, the band-shaped pattern is formed into a V-shape, U-shape, W-shape, or Y-shape. The accumulated water and the like can be easily drained by utilizing the partial deformation of the belt-shaped pattern. Further, by making the thickness of the band-shaped pattern larger than the width of the gap between the band-shaped patterns, it is possible to easily partially close the gap between the band-shaped patterns due to the partial deformation of the band-shaped pattern. In the present invention, “the gap extends in the traveling direction of the vehicle” includes a gap that extends obliquely with respect to the traveling direction of the vehicle.

According to the present invention, since the belt-shaped pattern is formed on the plate surface through which the vehicle passes, slip prevention equal to or more than that of the conventional circular or hexagonal pattern can be achieved. Moreover, when the vehicle passes through the plate surface, the gap between the belt-shaped patterns extends in the traveling direction of the vehicle tire, and the exit of the gap is also opened in the traveling direction of the vehicle tire. The closed portions of the gap due to the partial deformation of the adjacent belt-like patterns sequentially move in the direction of the exit of the gap as the vehicle advances, and water or the like accumulated in the gap between the belt-like patterns can be discharged from the outlet of the gap. In this manner, water or the like accumulated in the gaps between the belt-shaped patterns can be forcibly discharged using the pressing force of the vehicle tire passing through the plate surface, and dust and water accumulated on the plate surface can be reduced as much as possible. .

BEST MODE FOR CARRYING OUT THE INVENTION A rubber plate according to the present invention
It can be manufactured by a known manufacturing method.
By adopting the production method proposed in Japanese Patent No. 30522, the inside of a rubber plate, which is difficult to sufficiently apply heat during molding and vulcanize, can have a dense structure. In this manufacturing method, a rubber core material preliminarily vulcanized, a recycled rubber material in which a vulcanizing agent is mixed with a pulverized recycled rubber material, and a vulcanizing agent are mixed in a cavity of a mold for molding a plate. A rubber core material as a strong carrier, which is disposed along the center axis of the cavity by filling each of the raw rubber materials, and a recycled rubber material wrapped around the rubber core material. After forming a three-layer body of a layer and a raw rubber layer surrounding the recycled rubber material layer, the mold is heated to vulcanize the recycled rubber material layer and the raw rubber layer.

A V-shaped belt-shaped pattern 10 and an inverted V-shaped belt-shaped pattern 20 shown in FIG. They are formed alternately so as to be adjacent to each other. The gap 14 is formed along the strip pattern 10 and the strip pattern 20 as shown in FIG. In addition, as described later, the gap 14 extends in the traveling direction of the vehicle passing through the plate surface, and the exit of the gap 14 is also provided in the traveling direction of the vehicle. The V-shaped strip pattern 10 and the inverted V-shaped strip pattern 20 shown in FIG. 2 have the same shape except that the open portions 12 and 22 are opposite. This band-shaped pattern 10, 2
Reference numeral 0 indicates that the cutouts 12, 22 are provided in a regular triangle having a side of 30 mm. In addition, the belt-shaped pattern 10,
20 have a width M of 10 mm, and the adjacent band-shaped pattern 1
The gap width N between the gaps 14 and 14 between 0 and 20 is 2 to 5
mm (the gap width N of the gap 14 shown in FIG. 2 is 3 mm). Further, the thickness t (FIG. 3) of the band-shaped patterns 10 and 20 is 10 mm, which is larger than the gap width N of the gap 14.

A V-shaped strip pattern 1 shown in FIGS.
In the rubber level crossing plate in which 0 and 20 are formed through the gap 14, the partial deformation generated in the belt-shaped patterns 10 and 20 adjacent to each other due to the pressing force of the tire of the vehicle passing through the plate surface is used. 14 can be forcibly discharged. This will be described with reference to FIG. FIG.
When the pressing force is applied to the belt-like patterns 10 and 20 in which the sand particles are accumulated in the gap 14 shown in FIG. 1 by the vehicle tire moving from the A side to the B side, the sand particles in the gap 14 FIG. 3 shows a state of being discharged from the gap 14. First, as shown in FIG. 4A, when a pressing force is partially applied to the A-side portion of the V-shaped band-shaped pattern 10 and the inverted V-shaped band-shaped pattern 20, the band-shaped patterns 10, 2
Since the thickness t of 0 is larger than the gap width N of the gap 14,
The belt-shaped patterns 10 and 20 are easily partially deformed,
Some of the deformed portions of the strip patterns 10 and 20 come into contact with each other and partially close the gap 14. At this time, the gap 14
Are present in the gap 14 due to the deformation of the belt-shaped patterns 10 and 20 in the gap 14.
Move sideways. Further, since the gap 14 extends in the moving direction of the vehicle tire, the belt-shaped patterns 10, 2 are moved as the vehicle tire moves in the direction B and the pressing force moves.
The position where the gap 14 is closed due to the zero partial deformation also moves in the B-side direction. Therefore, finally, the sand particles 3 in the gap 14
, 0, 30... As shown in FIG.
Can be discharged from the side outlet.

As described above, by sequentially deforming the belt-shaped patterns 10 and 20 from the side A to the side B by the vehicle tire, water and dust accumulated in the gap 14 can be discharged.
On the other hand, when the vehicle tire travels in the direction from the B side to the A side, the belt-shaped patterns 10 and 20 are shown in FIGS.
Partially deformed in the order of (a), water and dust accumulated in the gap 14 can be discharged from the A-side outlet. For this reason, according to the rubber plate in which the belt-shaped pattern shown in FIG. 1 is formed on the plate surface through which the vehicle passes, even in rainy weather, pedestrians and the like who pass on the rubber plate repels rainwater when passing through the vehicle. Can be reduced as much as possible. In addition, dust such as sand accumulated in the gap 14 can be reduced as much as possible, and the appearance of the rubber plate having a colored plate surface on which the vehicle passes can be kept good for a long time. In the above description, the V-shaped band pattern has been described.
It may be a band shape of a letter shape, a W shape, or a Y shape, and FIG. 4 shows an example in which a Y shape band pattern is formed.
The Y-shaped belt-shaped patterns 40 are arranged in the same direction every other row in the X or Y direction in which the vehicle travels. The same is true. That is, the width of the band-shaped pattern 40 is 10 mm, and the gap width between the adjacent band-shaped patterns 40 is 2 to 5 mm. Further, the thickness of the band-shaped pattern 40 is 10 mm, which is larger than the gap width between the adjacent band-shaped patterns 40. In the band-shaped pattern shown in FIGS. 1 to 5, the band-shaped pattern may be partially thickened, may have two stripes, or may have an arabesque pattern, a swastika pattern, or a toe pattern in addition to a character pattern.

[0012]

According to the present invention, the belt-shaped pattern formed on the plate surface through which the vehicle passes prevents water and dust accumulated in the gaps of the belt-like pattern from passing along the vehicle while preventing slippage. Can be discharged. For this reason, it is possible to reduce as much as possible the repelling of rainwater when passing the vehicle to pedestrians and the like who pass through the rubber-like plate even in rainy weather, and the plate surface through which the vehicle passes is made of rubber. It is also possible to keep the appearance of the railroad crossing plate good for a long time. Therefore, it is suitable as a railroad crossing plate laid between railroad crossings.
