Abstract

PURPOSE:To prevent a slip accident by burying a plurality of rubber boards into a plate main body consisting of concrete in such a manner that the rubber boards are exposed at the same level as the surface of the plate main body. CONSTITUTION:A plate main body 1A having a specified thickness is formed with plane and square-shaped concrete. A plurality of rubber boards 1B are buried in the plate main body 1A in zigzag in such a fashion that the surface 1B1 of the rubber boards are exposed at the same level as the surface 1A1 of the main body 1. A suspension insert 1C is installed in the surface center of the plate main body 1A, thereby forming a non-slip plate 1. When executing construction work, mortar is placed on a consolidated base material. Using the suspension insert 1C, the plate 1 is suspended and laid out in the same orientation as for the vertical direction. The plate 1 is laid out as opposed to the top as for the horizontal direction. Furthermore, mortar or sand is put in the clearance between the plate 1 and the plate 1.

2. Description of the Related Art Recent winter roads in Hokkaido, especially roads in urban areas, are equipped with studless tires, so
It must be said that it is extremely dangerous for vehicles to travel and pedestrians to walk due to the abacus road and other factors.
The snow removal system did not catch up with the snowfall, traffic congestion, rear-end collision,
It has been pointed out that it causes various new traffic problems such as fractures due to falls. As measures against the above, there are a road heating method, a method in which rubber is directly attached to a road surface, and a method in which a snow melting agent is applied.

[0003]

The problems described in the prior art have the following problems. 1. The road heating method is not a good idea considering the high construction cost and maintenance costs. 2. If the rubber is stretched directly on the road surface, peeling may occur. 3. With the snow-melting agent spraying method, it is not a decisive factor when considering the number of spraying operations, personnel costs, and material costs. Therefore, most of the roads have to rely on conventional snow removal and snow removal.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide the following. In order to solve the problems such as the current snow removal to some extent, at the stage of making a concrete flat plate, the rubber is partially fixed in advance in the formwork, the concrete is driven in, and the concrete flat plate in which the rubber plate is integrated with the concrete is made.

The following dimensions were suitable. The flat plate body is 995 mm × 995 mm × 200 mm,
The rubber plate is 200 mm × 200 mm × 30 mm, the flat plate groove has a width of 10 mm and a depth of 5 mm, and the rubber plate groove has a width of 20 mm and a depth of 4 mm. The product strength of the one of the present application is configured so as to be able to cope with an automobile load of 25t. In addition, the shape of the rubber plate to be embedded can be changed to a round shape, a square shape, or the like. In addition to this, a rod shape that is perpendicular to the vehicle traveling direction, or a rubber surface with a section or a design is used. You can put it in.

[0016]

Since the present invention is configured as described above, it has the following effects. 1. Due to the properties of rubber such as ice that is hard to adhere and elasticity, the frozen pressure on the surface of the flat plate body is destroyed by the ground contact pressure of the vehicle tire, and the frozen road surface is eliminated because the surface of the rubber plate appears on the surface. 2. Not only the friction of the rubber plate but also the surface of the concrete flat plate body can be provided with a shallow groove for slip prevention, so that slip prevention can be performed more reliably. 3. Since the rubber plate is embedded and integrated when the concrete flat plate body is created, the rubber plate does not easily come off. That is,
When the flat plate body of concrete is made, the rubber plate is placed and the fresh concrete is placed, so that the adhesion between the concrete and the rubber plate becomes high, and the rubber plate does not easily come off. Also,
When the rubber plate is pasted after concrete molding, voids are generated around the rubber and it is easy to peel off due to the influence of water and ice. However, in the present application, since the rubber plate is brought into close contact when pouring concrete, there is no gap, so that the rubber plate is integrated.

4. The cost is low because a rubber plate is not provided on the entire surface but is partially embedded. 5. Construction is completed simply by laying a concrete flat plate, so workability is good and construction costs are low. Regarding the structure of the outer peripheral surface of the flat plate body, the surface of the flat plate body is a surface of concrete and a rubber plate. In addition, the side surface is formed by a formwork, and the bottom surface is a surface of concrete that is left untreated.

6. Since the characteristics of rubber are used and the frozen road surface is solved by transportation vehicles, maintenance costs are not incurred. 7. The combination of the groove on the surface of the flat plate body and the rubber plate eliminates the frozen road surface, prevents slippage, and does not spoil the appearance. 8. It can be colored and can be a flat plate that matches the surroundings. Regarding the color arrangement, there are many cases where color interlocking blocks are currently laid on the sidewalks, and it does not seem strange to color the roadway. 10. In the case where the entire surface is rubber-bonded, it becomes slippery when wet due to summer rain, etc., but since the present application has a concrete surface, there is no concern about that.
