DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip surface of a pavement road, and more particularly, to the prevention of slip due to ice and snow attached to the road surface.

[0002]

2. Description of the Related Art Conventionally, there are various types of non-slip on a pavement road surface. For example, a pavement road surface having irregularities of various shapes, and an asphalt containing rubber particles as an aggregate, So-called "rubit pavement" that pavements the road by mixing the surface and makes the surface layer of the road surface flexible
And so on. Road heating is also practiced in which a heating wire is buried beneath the surface of the road surface to melt the ice and snow attached to the road surface by the heat generated to prevent slipping.

[0003]

However, in such a conventional technique, when providing various shapes of irregularities on the surface of a pavement road, for example, complicated work is required in terms of construction. For asphalt pavement,
Since the material itself is soft and there is a possibility that the shape may change depending on the temperature in particular, it is impossible to carry out the method, and there is a problem that the method is limited to concrete pavement. In addition, in the so-called rubit pavement, it is difficult to control the temperature of the rubber granules to be contained in the asphalt at the time of construction, and the stirring process and the control of the particle size of each aggregate to be mixed are complicated.
Further, such a pavement road surface requires a long time in the construction, and when it is worn, it needs to be re-paved as a repair work in order to repair it, which also requires a long time. Also, such paved roads, once constructed, change the shape of the unevenness according to the conditions of ice and snow on the road surface, the traffic conditions of pedestrians and vehicles,
Alternatively, it was impossible to change the degree of flexibility of the surface layer after waiting for the resurfacing. Also, regarding road heating, the heating wire for heating is buried under the surface layer of the road surface, so the temperature of the road surface rises after a considerable time has passed after energization, so-called "rise" Was slow, and the amount of electricity used was uneconomical. The present invention has been made by paying attention to such conventional technology, and can be constructed and repaired immediately in a short time, can respond variously according to the environment and situation, and the construction cost is low,
When a heating wire is used, it is intended to provide an economical non-slip structure on a pavement surface, which rises quickly and is economical.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a non-slip structure for a pavement road according to the present invention is provided by forming a mesh-like sheet formed of an elastic body into a groove formed in a pavement road surface. It is planted in. Further, a heating wire for heating is incorporated in the elastic body forming the mesh-like sheet.

[0005]

Embodiments of the present invention will be described below. FIG. 1 is a perspective view showing one embodiment of the present invention, in which a mesh-like sheet 3 made of rubber is planted in a groove 2 formed in a surface of a pavement 1. The mesh sheet 3 made of rubber has a large frictional resistance by itself, and has a non-slip effect. Further, as shown in FIG. 2, even if ice or snow adheres to the surface of the pavement road 1 and the mesh-shaped sheet 3 is buried under the ice and snow layer 4, for example, the tire of the vehicle 5 and the like, the mesh-like sheet 3 is made of rubber and elastic,
It is crushed and deformed by the load received through the ice layer 4. When the mesh-shaped sheet 3 is deformed, ice and snow in the vicinity thereof are broken and easily peeled and melted, and the mesh-shaped sheet 3 itself acts as an anti-slip by being exposed to the outer surface. In addition, a groove 2 is recessed in the surface of such a pavement road 1,
With the configuration in which the mesh sheet 3 of the groove 2 is implanted, the flexible mesh sheet 3 can be fitted and implanted simply by forming a simple concave groove on the road surface.
Construction strength can be improved.

FIG. 3 shows an embodiment in which a heating wire 6 for heating is incorporated in the mesh sheet 3. Since the surface of the mesh sheet 3 is exposed on the surface of the pavement road 1. In addition, the heat generated by the heating wire 6 is easily transmitted to the road surface, so that the rise after the energization is quick, the amount of power consumption is small, and it is economical.

In each of the above embodiments, the surface of the mesh sheet 3 is made flat. However, the present invention is not limited to this example. If it is configured to further increase the frictional resistance by protruding from the surface of 1 or providing unevenness,
The anti-slip effect can be further enhanced, which is preferable. Further, when various aggregates such as sand are mixed into the rubber, the frictional resistance can be further increased, which is preferable.

[0008]

As described above, the anti-skid structure of the pavement surface of the present invention has the contents as described above, and can be constructed and repaired immediately in a short time, and can respond variously according to the environment and situation.
Moreover, the construction cost is low, and when a heating wire for heating is used, the start-up is quick and economical.
