Description

[Detailed description of the invention]

[00011

[Industrial Field of Application] The present invention relates to anti-slip surfaces for paved roads. Specifically, this is to prevent slips caused by ice and snow adhering to the road surface. [0002] [0002] Conventionally, there are various anti-slip methods for paved roads, such as those with various shapes of unevenness on the surface of paved roads, and asphalt containing rubber particles. The so-called "Ruvit pavement" is a method of paving roads by adding aggregate to the surface of the road, making the surface layer more flexible.
There are things called. Road heating is also being widely implemented, in which heating wires are buried under the surface layer of the road surface, and the heat generated by the wires melts ice and snow adhering to the road surface to prevent slipping. [0003]

[Problems to be Solved by the Invention] However, with such conventional techniques, for example, when providing irregularities of various shapes on the surface of a paved road surface, it requires complicated work and labor in terms of construction. For asphalt pavement,
Since the material itself is soft and there is a risk that its shape may change due to temperature, it is impossible to implement, and the problem is that it is limited to concrete pavements. In addition, in so-called Rubit pavement, it is difficult to control the temperature of the rubber particles contained in the asphalt during construction, and it is also complicated to control the stirring process and the particle size of each aggregate to be mixed. Furthermore, such paved roads require a long time to construct, and when they are worn out, it is necessary to re-pave them in order to repair them, which also requires a long time. In addition, once paved roads like these are constructed, the shape of the unevenness can be changed depending on the ice and snow conditions on the road surface, the traffic conditions of pedestrians and vehicles, etc., or the degree of flexibility of the surface layer can be changed. The only way to make changes was to wait until the time was right for resurfacing. In addition, with regard to road heating, heating wires are buried beneath the surface layer of the road surface, so the temperature of the road surface rises after a considerable amount of time has passed after electricity is turned on, causing what is called a "rise". It was slow and consumed a lot of electricity, making it uneconomical. The present invention
This was done by focusing on such conventional technology,
An economical anti-slip product for paved roads that can be installed or repaired instantly in a short period of time, can be applied in various ways depending on the environment and situation, has low construction costs, and when heating wires are used, starts quickly and is economical. It is intended to provide structure. [0004]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a mesh-like sheet formed of an elastic material on the surface of a paved road or a groove formed in the road surface. This mesh-like sheet is said to be one in which protrusions of elastic material are formed in a mesh-like manner on the surface of the base. Further, the elastic body is made of a flexible resin mixed with aggregate for increasing frictional resistance, and a heating wire is incorporated into the elastic body forming a mesh sheet. [0005]

[Operation] In the anti-slip structure for paved roads of the present invention, the mesh-like sheet attached to the surface of the paved road or planted in the grooves recessed in the road surface is made of an elastic material and has a shape. Since it is mesh-like, it has a large frictional resistance and has a non-slip effect when pedestrians and vehicles pass by. Furthermore, when an aggregate for increasing frictional resistance is mixed into the elastic body, the effect becomes even more remarkable. In addition, even if water or snow adheres to the road surface and the mesh sheet is buried under the layer of ice and snow,
When stepped on by a pedestrian's foot or the tire of a passing vehicle, the mesh-like sheet deforms due to the load received through the ice and snow layer since it is made of an elastic material. When the mesh sheet deforms under the ice and snow layer, the ice and snow in the vicinity cracks, peels off, and melts easily, and furthermore, the mesh sheet is exposed and acts as an anti-slip agent as described above. When heating wires are incorporated into the elastic body that forms this mesh-like sheet, the heat from the heating wires is easily transmitted to the road surface because the mesh-like sheet is exposed to the road surface. is faster and uses less electricity, making it more economical. [0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below based on the drawings. Note that the same reference numerals are given to the parts common to each embodiment, and redundant explanation will be omitted. Figure 1 shows paved road 1.
A mesh-like sheet 2 made of rubber, which is an elastic body, is attached to the surface using an adhesive. In the anti-slip structure for paved roads of the present invention constructed in this way, the rubber itself has a high frictional resistance and has an anti-slip effect, and as shown in FIGS. Even if ice or snow adheres to the surface of the mesh sheet 2 and the mesh sheet 2 is buried under the ice and snow layer 3, if the ice and snow layer 3 is stepped on by a vehicle's tailgate 4, for example, the mesh sheet 2 will be buried under the ice and snow layer 3. 2 is made of an elastic material, so it is swamped and deformed by the load received through the ice and snow layer 3. When the mesh sheet 2 is deformed, ice and snow in the vicinity are likely to crack, peel off, and melt, and the mesh sheet 2 itself is exposed on the outer surface, thereby acting as an anti-slip device. [00071] In FIG. 3, grooves 6 are formed in the surface of a paved road 5, and a mesh sheet 7 having a shape corresponding to the grooves 6 is planted. In this embodiment, the flexible mesh-like sheet 7 can be inserted and planted by simply forming a groove on the road surface, and the construction strength can be further improved. As shown in the figure, it has the effect of peeling off and melting the ice and snow layer 3 as in the previous embodiment. [0008] Illustrated in FIG. 5 is another embodiment in which the base 8
A mesh-like sheet 10 is constructed by forming mesh-like protrusions 9 on the surface of rubber, which is an elastic body. By doing so, the mesh-like sheet 10 can be more strongly adhered to the paved road 1. The other configurations and operations are the same as those of the previous embodiment, so redundant explanations will be omitted. [0009] FIG. 6 shows an embodiment in which heating wires 12 are incorporated into a mesh sheet 11, and the surface portion of the mesh sheet 11 is exposed to the surface of the paved road 5. The heat from the heating wires is easily transferred to the road surface, so the start-up is quick after energization, and the amount of electricity used is small, making it economical. [0010] When aggregate for increasing frictional resistance is mixed into these mesh sheets, the anti-slip effect becomes even more remarkable. In addition, by selecting the mesh shape of the mesh sheet and the aggregate for increasing frictional resistance, various types can be prepared in advance to accommodate various ice and snow adhesion conditions and pedestrian and vehicle traffic conditions. Moreover, construction and repair can be done in a short time by adhesion and fitting, which enables quick and diverse responses. [00111] [Effects of the Invention] The anti-slip structure for paved roads according to the present invention has the content as explained above, can be immediately constructed or repaired in a short time, and can be adapted to various environments and situations. Moreover, the construction cost is low, and when heating wires are used, it is quick to start up and is economical. This is useful, for example, when emergency anti-slip measures are taken on a road due to some kind of traffic situation, or when the environment changes and anti-slip measures are needed depending on the amount of ice or snow on the pavement surface. will be extremely effective.
