Abstract

PURPOSE:To prevent the drying-up of soil by a method in which through holes are formed in the thickwise direction of a flat plate tile, and fibrous assemblages consisting of arranged or entangled fibers are packed into the holes. CONSTITUTION:Soil G is horizontally leveled off, and cement S is applied to the contact position between one tile 10 and another tile 10. Sand D is put in the recession formed between the cements S to form a horizontal base on which the tiles 10 are to be placed. Before the cements S are dried, many tiles 10 are placed on the base. Rain water on the tiles 10 is directed into holes 20 through a groove 18, moves downwards through the holes 20 by the capillary action of the fibrous assemblages 22, and is absorbed through the sand D by the soil G.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to tiles laid on sidewalks and floors of buildings.

0002

2. Description of the Related Art Conventionally, tiles 100 have been laid using a construction method as shown in FIG. That is, the soil G is leveled almost horizontally, and the cement S is poured onto it. Then, before the cement S dries, the tile 100
Lay them out horizontally and vertically.

[Problem to be Solved by the Invention] Recently, serious problems such as accidents caused by cave-ins on sidewalks have occurred. This is said to be because, as mentioned above, the soil G is isolated from the outside air by the cement S and the tiles 100. In other words, soil G is said to be alive, but in order for soil G to survive, it must be in a state where it can easily absorb moisture in the air and rainwater, and must be able to absorb absorbed moisture easily. It is necessary to keep the water in a condition where it can be released into the outside air. This repetition of absorption and dissipation is what makes soil G
"respiration" and is an essential condition for activating soil G. If soil G is isolated from the outside air as in the past, activation of soil G will be hindered, and soil G will gradually become depleted. This depletion of soil G is the biggest cause of cave-in accidents on sidewalks.

[0004] Therefore, in order to prevent depletion of soil G, a tile having through holes extending through the thickness has been proposed. This tile was expected to allow, for example, rainwater to flow into the soil or to evaporate moisture in the soil through the through holes.

However, if a tile is simply provided with a through hole, when it is laid on a sidewalk, there is a problem in that sand and small stones can get into the through hole and block the through hole. In addition, tiles are mostly made of cement that contains calcium, so they are susceptible to acids, and if acid rain falls, the surface of the through-holes will dissolve and harden again, causing the through-holes to become clogged. was there.

[0006]

[Means for Solving the Problems] Therefore, in order to solve the above problems, the following measures were taken.

That is, the tile of the present invention is a flat tile, and is provided with a through hole penetrating in the thickness direction.
The through hole is filled with a fiber aggregate formed by aligning or intertwining a large number of fibers.

[0008] Preferably, a recess is provided on the surface of the tile, and the through hole opens in the recess.

[0009]

[Function] In the tile of the present invention, since the fiber aggregate is provided in the through-hole, sand and small stones do not enter the through-hole.

[0010] Furthermore, rain falling on the tiles moves downward through the through holes and is absorbed into the soil due to capillary action caused by the fiber aggregates. On sunny days, water in the soil moves upward through the holes due to capillary action in the fiber aggregate, escapes above the tiles, and evaporates.

[0011] In this way, depletion of the soil can be prevented without clogging the through holes, and the soil can be activated.

[0012] If a recess is provided on the surface of the tile and the through hole is opened in the recess, rainwater can be easily guided to the through hole. Thereby, soil depletion can be prevented even more effectively.

[0013] Examples of the fibers to be filled in the through holes include glass fibers, synthetic resin fibers, rock fibers, slug fibers, and ceramic fibers. That is, it is preferable because it has excellent weather resistance. More preferably, this fiber contains an alkaline substance.

[0014] The size of the fiber aggregate made of the above-mentioned fibers is not particularly limited, but usually has a diameter of about 3 to 10 mm. Note that it is preferable to harden the periphery of the fiber aggregate with resin to such an extent that the flow of moisture is not hindered. This can prevent a large number of fibers from coming apart inside the through-hole.

[0015] Any composition may be used to form the tile body, but 60 to 80% of aggregate made by finely pulverizing household waste or industrial waste, and solidified aggregate may be used. It is preferable to use a curable composition obtained by kneading 40 to 20% of a coagulant containing silica as a main component in a vacuum for the following reasons.

[0016] In order to solve the waste disposal problem that has become a problem recently, it is extremely suitable to reuse industrial waste.

[0017] Examples of the aggregate include debris from old buildings, slag remaining after thermally melting underground resources such as iron ore, papermaking slag, household incineration ash, and sludge. By kneading such a pulverized aggregate with the coagulant, the pulverized material is covered with the coagulant. As a result, even if the pulverized material contains a substance with poor weather resistance, it will be protected by the coagulant mainly composed of silica.

The coagulant is called alumina silicate cement, and in addition to silica, it contains alumina, sodium,
Contains calcium, titanium, iron, etc. The inventor has already filed a patent application regarding the above-mentioned curable composition (JP-A-1-148510, JP-A-1-148510, JP-A-1-148510).
No. 148506, Japanese Patent Application No. 1-119261, Japanese Patent Application No. 1

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show a tile 10 to be laid on the floor of a sidewalk or building, and has dimensions of, for example, 20 cm in length and width and 6 cm in thickness.

[0021] The tile 10 of this example was formed in two molding steps.
It is obtained through a so-called double punching process, and is composed of an upper layer 12 formed in the first process and a lower layer 14 formed in the second process.

The upper layer 12 is made of a composition obtained by finely pulverizing igneous rock such as granite or basalt, and kneading the pulverized material with the above-mentioned coagulant mainly composed of silica in a vacuum. By using this composition as the upper layer of the towel 10, it is possible to obtain a tile 10 with a glossy surface, high hardness, and excellent weather resistance.

The lower layer 14 is made of a composition obtained by kneading aggregate obtained by finely pulverizing blast furnace slag and the above-mentioned coagulant in a vacuum. By molding the lower layer 14 with this composition, the following effects can be obtained. That is, conventional tiles are mainly molded from Portland cement and therefore contain a large amount of calcium. For this reason, it is weak against acids, and for example, when acid rain falls, the surface of the tile will dissolve due to the acid rain. However, if the lower layer 14 of the tile 10 is formed from the composition, even if the blast furnace slag contains a substance that is susceptible to acids, the coagulant mainly composed of silica will cover and protect the substance. Therefore, there is no need to worry about it dissolving even if acid rain falls.

Reference numeral 18 denotes a flat, square-shaped groove formed as a recess on the surface of the tile 10. The shape of this groove 18 is not limited to this, and may be round, triangular, or other shapes. Reference numeral 20 is a through hole provided in the tile 10 and penetrating in the thickness direction. This through hole 2
The diameter of 0 is approximately 10 mm. In one tile 10, a total of 33 through holes 20 are provided, all of which open in the grooves 18. The diameter and number of the through holes 20 are not limited to those described above, and the shape of the through holes 20 is not particularly limited.

[0025] Note that the groove 18 is not necessarily necessary;
Although the through-holes 20 may be open on the upper surface of the tiles 10, by providing the grooves 18, it becomes easier to guide rainwater that has fallen on the tiles 10 to the through-holes 20.

Reference numeral 22 denotes a fiber aggregate arranged inside the through hole 20. This fiber aggregate 22 is made by aligning a large number of glass fibers. As long as the fiber aggregate 22 causes capillary action, there is no particular limitation on the amount of glass fiber used. Note that the fiber aggregate 22 is not limited to the one made by aligning glass fibers as described above, but may be intertwined like a nonwoven fabric. In this case, it is preferable to use a fiber aggregate 22 having a higher water permeability in the vertical direction than in the lateral direction.

Next, a process of laying a sidewalk using a large number of the tiles 10 described above will be described, but the method is not limited thereto.

As shown in FIG. 3, first, the soil G is leveled. and one tile 10 and the other tile 10
Apply cement S to the location where they will be joined. Cement S
Sand D is poured into the recess formed between the tiles 10 and the cement S to create a horizontal base on which the tiles 10 are laid. A large number of tiles 10 are laid before the cement S dries. FIG. 4 shows a plan view after the tiles 10 have been laid.

When the tile 10 of the present invention is laid as described above, rainwater falling on the tile 10 flows through the grooves 18 and is taken into the through holes 20. Then, due to the capillary phenomenon caused by the fiber aggregate 22 provided in the through hole 20,
Rainwater moves downward in the through hole 20, passes through the sand D, and is absorbed into the soil G. Thereby, depletion of soil G can be prevented. In addition, a fiber aggregate 22 is provided in the through hole 20.
is provided, so sand and small stones on the sidewalk do not enter the through hole 20 and clog the through hole 20.

Furthermore, when the temperature is high such as on a sunny day or when the air is dry, the moisture contained in the soil G and sand D is absorbed into the through holes 20 by the capillary action of the fiber aggregates 22. It is taken into the interior, moves upward in the through hole 20, and evaporates.

[0031] When the soil G repeatedly absorbs and releases water as described above, in other words, when the soil G "breathes", the soil G becomes activated, thereby preventing sidewalk cave-in accidents. You can also do that.

In this example, the tiles 10 provided with the through holes 20 are laid on the sidewalk, but the present invention is not limited to this. Through holes are provided in the tiles already laid on the sidewalk, and the fiber aggregates 22 are placed therein. You can insert it.

[0033]

[Effects of the Invention] Since the tile of the present invention is provided with a through hole penetrating in the thickness direction, and the fiber aggregate is provided in this through hole, the through hole is not clogged with sand or the like. Also, with the help of capillary action caused by fiber aggregates, water can flow effectively into the soil, preventing soil depletion. Water evaporates from the soil quickly due to the fiber aggregate, thereby activating the soil.

[0034] If a recess is provided on the surface of the tile and the through hole is opened in the recess, rainwater can be easily guided to the through hole. Thereby, soil depletion can be prevented even more effectively.
