Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete product for forming a road surface, and more particularly to a concrete product for forming a walking or running road surface, which obtains a preferable anti-slip effect, ensures safety in use of the road surface, and It is intended to provide added value such as improved aesthetics and air pollution.

[0002]

BACKGROUND OF THE INVENTION Concrete products often form at least a portion of a road surface. That is, today, not only concrete plates laid on the road surface in the form of treads, but also the top surfaces of gutters and the lids for the openings thereof, and at least a part of the boundary blocks and the like, or a state where the majority surface is exposed to the road surface As such, the exposed surface forms at least a portion of the road surface.
However, such a concrete product for forming a road surface as described above is generally installed simply with a flat concrete surface exposed.

In recent years, regarding the above-described concrete products for forming a road surface, regarding the arrangement of a tile pattern or the like to improve the appearance of the road surface, the present applicant has filed Japanese Utility Model Application No. 3-103250. Or design tenth
No. 19614 (Japanese Patent Application No. 3-31751) has been proposed to improve the appearance of a conventional mere concrete surface and to beautify roads and urban areas.

[0004]

In the above-mentioned prior art, there is a high possibility of slipping on the concrete surface, especially when raining. In other words, it is clear that on a smooth concrete surface, moisture acts as a lubricant between the pedestrian's shoes and the back of the shoe, and it is easy to cause slippage, especially during rainfall, sprinkling and snowfall. It is necessary to walk while paying attention, and this is the same with the tires even when running on wheels.

[0005] In the case where the above-mentioned tile pattern is provided, unevenness is formed on the road surface, so that it seems that a certain anti-slip effect can be obtained. Even if the groove formed between them can perform a drainage action, due to the adhesion or adsorption of water or the accumulation of flying dust and soil particles,
There is a tendency for water to accumulate in the grooves, and sufficient drainage is not achieved, moisture remains as such, and such residual moisture also covers the surface of the tile pattern rows that protruded due to the surface tension of water. However, the tile pattern rows are also liable to slip, and particularly, the tile pattern rows arranged in a row show directionality as a whole, and may act as a guide to the sliding action.
In any case, there is a high possibility that slippage occurs during rainfall or the like.

[0006]

SUMMARY OF THE INVENTION The present invention has been studied to solve the problems in the prior art as described above, and in a concrete product for forming a road surface as described above, a specific projection or the like is provided on the surface thereof.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a first embodiment of the present invention; FIG. On the surface of the side groove cover 1 where the handle portion 11 is appropriately disposed, a tile-shaped protruding plate surface 9 having a rectangular shape in FIGS. 4 to 7 or a circle in FIG. 8 or an oval shape in FIG. Is disposed as shown in the figure as a thickness of about 1 to 3 mm from the surface of the gutter cover 1.

Further, on the tile-shaped protruding plate surface 9, protruding portions 10 each having a height of 0.5 to 2 mm and various circular, square or star shapes as shown in FIGS. One side or diameter of each protruding portion 10 is about 1/10 to 1/3 of the length of each side of the plate surface 9, particularly 6
It is about 1 to 4 minutes.

4 to 9 show that the protrusions 10 are arranged at intervals of 1 to 3 times, preferably 1.5 to 2.2 times the diameter or the length of one side as described above. As shown in each of the drawings, each protruding portion 10 is formed as a pattern of a concentric three-dimensional protruding shape. In any case, each protruding portion 10 is shown in FIGS. In the case where the surface of the product 1 is simply flat, the height of the projecting plate surface 9 and the height of the projecting portions 10 are projected from the surface of the side groove cover 1 as shown in FIG. When the water film 20 due to rainwater or the like is stored and adsorbed on the entire surface with a uniform thickness as described above, the tile-shaped projecting plate surface 9 as described above is formed. 11
As described above, the surrounding water is introduced into the groove-shaped portion 12 between the tile-shaped projecting plate surfaces 9, 9, and a relatively thin water film 20 is formed on the projecting plate surfaces 9, 9.

Further, in the present invention, since a plurality of protruding portions 10 are provided on these protruding plate surfaces 9 as described above, shoe soles of pedestrians and the like are placed as shown in FIG. The water on the top surface of the protruding portion 10 that makes contact is extremely small, and the shoe bottom directly contacts the pattern formed as shown in FIGS.
In other words, the unevenness of the sole of the shoe to prevent slippage is effectively fitted and locked to the protruding portion 10, and the slippage can be prevented from the surface of the structure as an individual and the surface of the moisture acting as a lubricant. Prevent the occurrence exactly. In addition, since the projecting portions 10 are uniformly distributed over the side grooves or the entire surface of the lid, it is possible to prevent a pedestrian or a vehicle from slipping from all directions.

FIGS. 13 to 16 show an embodiment in which the above-described present invention is applied to a concrete concrete product used on a road. That is,
13 and 14 show a case where the opening is adopted as a road-side groove. In the U-shaped groove 2, the upper surface 14 of the side wall-shaped rising portion 13 formed on both sides of the opening 15 and the opening 15 are continuous. On the surface of the side groove cover 1 set to fit
The configuration of the present invention using the tile-shaped plate surface 9 and the projecting portion 10 provided on the plate surface 9 as described above is adopted. In addition, as shown in FIG.
Alternatively, even when the tile-shaped protruding plate surface 9 having the protruding portion 10 is used to have a width slightly smaller than the entire width of the lid, the area of the upper surface 14 of the side wall-shaped rising portion 13 is sufficiently small, so that almost the same anti-slip effect is obtained. Can be obtained. In addition, as shown in FIG. 14, when the tile-shaped protruding plate surface is applied only to a partial width instead of the entire surface of the side groove, in order to make the entire width surface the same height, instead of the protruding plate surface, the periphery is concave. Even when a plate-like body having a groove is employed, the same preferable anti-slip effect can be obtained.

In the case of the gate-side groove 3 shown in FIG. 15, the top surface 16 and the central opening 1 formed in the top surface 16 are formed.
A non-slip configuration including the tile-shaped plate surface 9 and the protruding portion 10 of the present invention is adopted for the entire surface of the side groove cover 1 fitted and set to 7. As described above, substantially the same effect can be obtained as shown in FIG. 16 as in the case of the U-shaped side groove shown in FIG. 14, or even when the width of the plate surface is further reduced. FIG. 16 also employs a plate-like body having a concave groove at the same height as the top end of the gutter instead of the tile-like protruding plate surface as in FIG. What can be done is as described above.

FIG. 17 shows a drop-in type waterway block 4 in which a drop-in slit 18 for draining the road surface is formed in the middle of the top surface 16 and FIG. 18 shows a slit hole 18a partially formed. 19 shows a culvert-type waterway block 5 in which the top surface 16 is closed, and FIG. 20 shows a notch 19 in which the top surface 16 is inclined so as to install a sidewalk boundary block at the end. Formed culvert type waterway block 5a
However, an effective anti-slip action can be obtained by adopting a configuration mainly including the tile-shaped protruding plate surface 9 and the protruding portion 10 on the top surface 16 thereof.

FIG. 21 shows a case where the present invention is applied to a flat road surface block 6 used for a sidewalk surface, and FIG. 22 shows a case where an interlocking block 7 used for a roadway and a sidewalk surface is a product of the present invention. Further, FIG. 23 shows a case where the present invention is applied to the pedestrian road boundary block 8. In these cases as well, an effective non-slip characteristic is obtained on the surface or the top surface thereof, and the pedestrian in the case of rain or the like is obtained. Ensuring safety such as described above is as described above.

FIGS. 24 to 27 show a tile-shaped projecting plate surface 9 using another structure of the present invention. That is, the case where the linear projecting portions 10a having appropriate lengths are appropriately combined in different directions is adopted as shown in FIGS.
5 and FIG. 26, and FIG. 27 shows the plate surface 9 formed by combining the dogleg-shaped protrusions 10b. These projections 10a and 10b also effectively prevent slippage as described above.

FIG. 28 shows an embodiment in which the above-mentioned one shown in FIG. 24 is employed in the side groove cover 1. The direction of the linear projection 10a or the U-shaped projection 10b is changed.
By making various changes and combining them, it is possible to obtain a preferable non-slip even in the case of a linear pattern as a whole, and to bring about a change in the design of the landscape.

FIG. 29 shows an embodiment of a road sidewalk constructed using the above-described product of the present invention. That is, the interlocking block 7 as shown in FIG. 22 is employed in the sidewalk, the U-shaped side groove 2 as described above is employed in the private area, and the sidewalk boundary block 8 is directly provided in the roadway. By adopting the drop-in waterway block 4 shown in FIG. 17 which can be placed on the sidewalk, it is preferable to provide a sidewalk having a preferable non-slip mechanism and a roadway end in consideration of prevention of vehicle slippage during rainfall or snowfall. It is clear that the pavement is properly formed.

Separately, according to the present invention, the entire surface of the tile-shaped projecting plate surface 9 is replaced with the projecting portion provided on the tile-shaped projecting plate surface as shown in FIGS. By forming a finely roughened layer or forming a thin layer of a rubber material layer or a powder material layer using an adhesive paint, the same anti-slip effect as that of the protruding portion can be obtained.

That is, in FIG. 30, the tile-shaped projecting plate surface 9 is subjected to a washing process or a blasting process.
Non-slip surface 2 with fine protrusions of about 0.2 to 2.0mm
1 and the same anti-slip effect as the above-described protrusion can be obtained.

FIG. 31 shows a rubber chip layer 2 in which a recycled rubber chip of about 1 to 2 mm is attached to a tile-shaped projecting plate surface 9 with an adhesive or the like as an example of a rubber material layer.
No. 2 is formed. By using the rubber material, it is possible to obtain a desirable anti-slip effect, and by using a rubber chip layer of color, the joints become clear and the tiles rise, making it clear and clear. Not only is it possible to form an aesthetic appearance that is immediately adapted to the scenery, but also to provide a pavement surface that is soft to the touch due to appropriate cushioning properties, is safe even if it falls down, and is pleasing to pedestrians.

In FIG. 32, as an example of the powdery material layer, a coating layer 23 in which hard material particles such as silica sand or recycled glass and an adhesive resin paint are mixed is applied to the tile-shaped projecting plate surface 9. This is shown. By using the hard material particles, it is possible to obtain the same anti-slip effect as the above-mentioned projecting portion, and by giving an appropriate color to the resin paint, as with the color rubber chip,
It is clearly clear and can create a landscape that matches the surrounding landscape. Furthermore, FIG.
By applying a non-slip surface, a rubber chip layer, a coating layer, and the like indicated by 32 to the entire surface including the groove portion 12, it is possible to match the surrounding scene more.

Although an example in which a protrusion or a roughened layer, a rubbery material layer, or a powdery material layer is used on the entire surface of the tile-shaped protruding plate has been described above, even when it is partially used, It has the same anti-slip effect, is more economical than adopting it all over, and adapts to the current situation. The same can be said for the case where the present invention is applied to the surface of a plate-like body having a concave groove on the periphery.

In the case of a protrusion or a roughened layer, or a rubbery material layer or a powdery material layer using an adhesive paint, 1 to 4
By adopting as multi-colors of colors, mosaic symbols, numbers and addresses, symbol marks such as prefectural emblems and city emblems, or pictures and patterns of flowers, insects, animals, boats and cars, etc.
The cityscape can be changed, the first-time visitors can recognize the place, it can give little children and lower grades a playful feeling, and the use of color, especially in the eyes of walking people You can make it feel easy and fun.

FIG. 33 shows an example of a prefectural emblem (Miyagi prefecture) as an example of a picture or pattern such as the above-mentioned mosaic-like sign or symbol mark.
34 shows flowers (tulips), FIG. 35 shows fruits (apples), FIG. 36 shows a boat (yacht), FIG. 37 shows directions, and FIG. 38 shows a car. In particular, as shown in FIG. 36, in the case of the configuration with or without the protrusion, the adoption is limited to a simple picture or pattern that can be expressed in one color.
The same applies to the roughened layer.

Further, as an example of the case where the above-mentioned mosaic-like picture is applied to the gate-shaped side gutter similar to that shown in FIG. FIG. 39 shows the result. In addition, as an example in which a mosaic picture for guidance is given to a lid portion of a gate-shaped side groove similar to FIG. 16 in which a tile-shaped projecting plate surface or a plate-like body having a concave groove around the part is formed, As shown in FIG.
In the figure, the mosaic-like picture is applied only to the beam portion of the gutter or only to the lid portion, but it goes without saying that the painting may be applied over the beam and the lid. The above-mentioned mosaic picture is composed of coating layers such as black 24, green 25, red 26, blue 27, etc. In addition, the color of the rubber chip or the adhesive resin paint is set to yellow, gray, brown or the like. Thus, various mosaic-like pictures can be obtained. Also, although not shown, the size of the plate-like body having the tile-shaped protruding plate surface and the periphery formed as a concave groove is 1/1 of that shown in the figure.
By making it as small as 2 to 1/4 or making the distance between the protruding plate surfaces narrower and denser, finer, clearer and more diverse mosaic pictures can be formed.

The mosaic-like pictures shown in FIGS. 33 to 40 are shown as being applied to a part of the surface of a gutter beam or a lid.
It is also conceivable that it is applied over the whole surface or over several. As such an example, FIG. 41 shows the score on the entire surface of the gate-shaped gutter, and FIG. 41 shows the case where the flow of water is expressed by using all the gutter lids set to fit into the openings of the U-shaped gutter. FIG.
Shown as 2. When installing such gutters, it can be used for the entire length to properly obtain the anti-slip effect, and also to make the mosaic-like symbols, pictures and patterns consistent, so that the surrounding landscape can be more Although it can be harmonized, it is possible to achieve the purpose more economically by using only one point only for the part where the anti-slip effect is desired. Or, conversely, it is also possible to form a symbol or a picture by applying a non-slip processing to the entire length and the entire surface and not performing a non-slip processing only at a portion desired to be a mosaic-like picture. As described above, this can be applied to other concrete products such as a flat plate, a sidewalk boundary block, and an interlocking block.

Next, a protrusion, a roughened layer, a rubbery material layer, a powdery material layer using an adhesive paint, or the like is partially formed on a tile-like projecting plate surface or a plate-like body having concave grooves on the periphery. An example is shown in which a simple geometric pattern is applied, but for simplicity, the description will be made assuming that the coating layer 24 is entirely black. FIG. 43 shows a case where a large protruding plate surface or nine plate-like bodies shown in FIGS. 33 to 38 are used as a set and a black coating layer is applied alternately to form a large checkered pattern.
As shown in the figure, a plurality of protruding plate surfaces or plate-like bodies can be employed to increase the size of the pattern. Conversely, only one or two pieces can be employed to reduce the size of the pattern. In addition to the checkered pattern, various patterns such as vertical stripes, horizontal stripes, diagonal lines, wavy lines, and lattice patterns can be easily applied. By applying such a geometric pattern to the entire surface or a part of the concrete product for forming a road surface, it is possible to easily improve the aesthetics while obtaining a favorable anti-slip effect as in the case of a mosaic-like picture. it can.

FIG. 44 also shows an example of a geometric pattern, in which the present invention is applied particularly to a circular protruding plate surface or a plate-like body. These square frame patterns can also change the thickness of the lines freely by applying a color as a set of several adjacent protruding plate surfaces, and also checkerboard patterns, vertical stripes, horizontal stripes, diagonal lines, Various patterns such as a lattice pattern can be easily applied.

FIG. 45 shows a concrete product for forming a road surface formed by appropriately combining rectangular projecting plate surfaces or plate-like members having a large and small square shape and a rounded corner with a black coating layer 24. It has been subjected to a learning pattern. As described above, only one kind of the protruding plate surface or the plate-like body used for the concrete product for forming the road surface is used, as shown in FIG.
The present invention can be applied to a combination of several types as shown in FIG.

In FIG. 46, a rhombus-shaped projecting plate surface or a plate-like body is partially provided with a black coating layer 24 to form a geometric pattern. As described above, the present invention can be applied to any shape or combination of the protruding plate surface and the plate-like body as long as it is a simple geometric pattern. Although all of these geometric patterns have been described as black coating layers for explanation, it goes without saying that other colors such as red, blue, and green can be employed as one or multiple colors. It's fun, too, and it excites people passing by. Also, in addition to the coating layer, of course, even if a protruding portion, a roughened layer, or a rubber material layer is adopted,
Preferable aesthetics can be added to the concrete product for forming a road surface while appropriately giving a non-slip action.

On the other hand, a photocatalyst is applied to the concrete or powdery material layer or the rubbery material layer of the projecting portion including the tile surface or the roughened layer, which is applied to the tile-shaped projecting plate surface or the plate-like body having the concave groove on the periphery. By mixing powdery or granular titanium oxide, which has an action, it reduces the harmful gases in the atmosphere, such as nitrogen oxides and sulfur oxides, as well as malodorous substances and organic halogen compounds, while obtaining a favorable anti-slip effect. become able to.

That is, when ultraviolet rays contained in sunlight shine on titanium oxide, electrons are excited and emitted from titanium oxide. The emitted electrons react with oxygen and water in the atmosphere to generate active oxygen (free radicals).
Next, the active oxygen undergoes an oxidation-reduction reaction with the harmful gas described above, whereby nitrogen oxides are changed to nitric acid, sulfur oxides are changed to sulfuric acid, and malodorous substances and organic halogen compounds mainly contain carbon dioxide. Becomes harmless substance. Some of the substances after these changes are adsorbed on the titanium oxide surface and impair the photocatalysis, but the adsorbate elutes in water due to rainfall and is removed from the titanium oxide surface to restore the photocatalysis again. . In addition, eluted substances such as nitric acid and sulfuric acid do not adversely affect the environment because they are extremely small. In this way, by mixing titanium oxide into the protruding portion, the roughened layer, or the powdery material layer or the rubbery material layer, harmful gases contained in the atmosphere can be rendered harmless, and the photocatalytic action of titanium oxide is It can be maintained semi-permanently.

The present invention as described above is applied to the surface of a concrete product for forming a walking or vehicle traveling road surface, and has a rectangular, circular, or elliptical tile-shaped protruding plate surface. Alternatively, a plate-like body having a concave groove around the periphery is formed, and a plurality of protrusions are disposed on the protruding plate surface or the plate-like body, and the height of the protrusion is from the surface of the concrete product. By adopting the height of the tile-shaped protruding plate surface and the plate-shaped body, the tile-shaped protruded plate surface and the plate-shaped body are combined with a plurality of protrusions, so that the plate surface and the plate surface can be used during rainfall and the like. Under the condition that the plate-shaped body is drained, the anti-slip effect of the plurality of protrusions can be obtained. Therefore, even if the plurality of protrusions described above have a relatively small amount of protrusion, stable operation can be achieved. The anti-slip effect, Strength parts, it is possible to secure a stable slip action to enhance the durability.

By forming a roughened layer, a powdery material layer using an adhesive paint, or a rubbery material layer on a tile-shaped projecting plate surface or a plate-like body having concave grooves on the periphery,
The same anti-slip effect as that of the protruding portion can be obtained.

By employing protrusions and roughened layers, or rubbery material layers of various colors, or powdery material layers using an adhesive paint, mosaic-like symbols, numbers, pictures, and geometric shapes can be obtained. It can compose patterns, give children a playful feeling, is easy on human eyes,
It gives the expectation and enjoyment of walking and can improve the beauty of the cityscape.
