Description

[Detailed description of the invention] [Field of industrial application] This invention relates to the improvement of water-permeable paving materials to facilitate the infiltration of rainwater and other water into the ground. It is possible to firmly bond wood and ceramic flat plate.

[Prior art] Conventional pavement materials include tiles, concrete plates,
Because it is made of asphalt, it has poor water permeability, and as the paved area of roads and other roads has increased in recent years and drainage facilities have been expanded, this has become an obstacle for rainwater and other water to seep into the ground, causing groundwater leakage. This caused a decrease in surface area and depletion of groundwater, and also caused problems in the growth of plants.

As a result of repeated research and development into a paving material that has water permeability and does not impair its aesthetic appearance, the applicant has previously published Utility Model Application Publication No. 127716/1983 using commonly used tile raw materials such as feldspar, pottery stone, and clay. By filling raw material powder, which is a mixture of granular viscous grains, etc. in which granular manganese, mica, or pigments are added, into a tile mold and press-molding it with a press, etc., an approximately flat plate-shaped element body is formed. form,
The body is then fired in a firing furnace to create a flat plate with a pattern such as a speckled pattern on the surface by firing the viscous grain pigments mixed with the raw material powder such as manganese, mica, or pigments. Then,
A water-permeable paving material was completed in which the flat plate described above was adhered to the surface of a concrete reinforcing base material and a plurality of drainage holes were drilled therein.

[Problems to be solved by the invention] The above-mentioned water-permeable paving material made by the present applicant has drainage holes visible as part of a pattern such as a spotted pattern, which enhances the aesthetic appearance, is sufficiently weather resistant, and is inexpensive. However, as a result of further research, it was discovered that the adhesion between the ceramic flat plate and the concrete reinforcing base material was poor and there was a risk of them peeling off. .

[Means for Solving the Problems] The present invention was made to improve the above-mentioned conventional drawbacks, and consists of placing a mortar layer on the surface of a concrete layer made of uncured coarse crushed stone, On the surface of the mortar layer, a flat plate made of ceramic material with a plurality of cone-shaped water permeable holes that expand downward is crimped onto the surface of the mortar layer, and a part of the mortar layer is placed below the water permeable holes in the flat plate. It is hardened in a form that bites into the inner periphery.

[Function] Therefore, the permeable paving material according to the present invention can be used by laying it on sidewalks, parks, etc. in the same way as conventional sidewalk boards, interlocking boards, etc.

[Example] (First Example) An example of the present invention will be explained below in detail with reference to Figures 1 to 8 according to the drawings. After filling the concave portion 3A of the lower mold 3 with a commonly used viscous powder 1 mixed with grains ^{2, etc.} , as shown in FIG. At this time, if approximately conical pins 5, 5, . , 6, ... are formed in the flat plate-like element body 10 as the eighth
It can be molded as shown in the figure, and its size is:
1mm in diameter so as not to interfere with normal walking.
Holes of about 7 mm to 7 mm are most suitable.

Next, when the element body 10 is fired in a firing furnace such as a tunnel kiln (not shown) in a conventional manner, the pigment of the viscosity particles 2, which is a granular mixture of manganese, mica, or pigment mixed in the viscosity powder 1, etc. is fired, and a speckled pattern 7 appears on the surface.
Patterns such as the above are formed, and the flat plate B of the ceramic material is completed.

Next, as shown in FIG. 1, an iron plate 12 with rods is placed on the bottom of the frame 11 for making a reinforcing base material, and is pressed against the frame 11 by applying it to the iron plate 14 in which holes 13 are made. Concrete 15 using coarse crushed stone is filled while vibrating the frame 11 for making the base material, and then a thin layer of mortar 16 is applied, and the mortar 16 is inserted and fixed into the hole 17A provided at the tip of the rod 17 of the iron plate 12. The rubber 18 thus formed is pressed so as to be inserted into the plurality of water permeable holes 6, 6, . . . of the flat plate B to integrate them.

Although the explanation is complicated, at this time, the water permeable hole 6 of the flat plate B is moved downwardly as shown in the enlarged view of FIG. The rod 17 of the bar iron plate 12 is drilled in a substantially conical shape such as a conical shape or a pyramid shape that expands toward the direction.
The diameter of the rubber 18 at the tip of the rod 17 is made slightly smaller than that of the rod. Therefore, during pressing, the outer periphery of the upper end of the rubber 18 provided at the tip of the rod 17 comes into contact with the inner surface of the drain hole 6, and the mortar 16 is the water drain hole 6
In addition to further preventing leakage, the space 6A formed between the outer periphery of the rubber 18 and the inner surface of the drain hole 6 can be filled with mortar, which is an adhesive.

Next, the rods of the iron plate 12 with rods are pulled out downward, and then, with the permeable paving material A integrated on the perforated iron plate 14 placed on it, it is pushed downward while being pressed from above the flat plate B, and the perforated iron plate 14 is pushed out. If the material is moved and left to harden at room temperature, the water-permeable pavement material A will be completed.

The reason why the rubber 18 is attached to the tip of the rod 17 of the bar-shaped iron plate 12 is to prevent the flat plate B from cracking when pressed, and also to prevent dimensional errors in the water permeable hole 16.

(Other Examples) The present invention is not limited to the above-mentioned examples. For example, a flat plate made of ceramic material may be made without any contaminants such as granular manganese, or a base plate made of concrete may be used. This can be modified without departing from the gist, such as by placing mortar on the surface of a pre-hardened or semi-hardened material and pressing a flat plate to make it stick. .

[Effects of the invention] As described above, in the present invention, a part of the mortar layer bites into the lower inner periphery of the cone-shaped water permeation hole provided in the ceramic flat plate and hardens. The reinforcing base material is firmly bonded and there is no risk of peeling, and the ceramic material is bonded to a flat plate made of feldspar, pottery stone, etc.
By filling a tile mold with a raw material powder that is a mixture of common tile raw material powder such as viscosity powder and granular viscosity particles containing granular manganese, mica, or pigments, and press-molding with a press etc. When a substantially flat plate-like element is formed, the plurality of drainage holes can be seen as part of a spotted pattern, so it can be laid out on a sidewalk or the like without spoiling the aesthetic appearance.

In addition, it does not prevent rainwater from entering the ground and does not hinder the growth of plants, and is extremely aesthetically pleasing and has high commercial value.In addition, the reinforcing base material is made of concrete. from,
It has good dimensional accuracy, can be manufactured at low cost, and can provide a water-permeable pavement material with extremely high industrial value.
