[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a floor stone installation structure and an infiltration method according to the present invention will be described in detail with reference to the accompanying drawings.

[0018] [I] Basic Concept of the Embodiment First, the basic concept of the embodiment will be described. The embodiment relates to a floor stone installation structure and a penetration method.

[0019] "Floor stone installation structure" is a concept that refers to a structure in which floor stone is laid, and includes, for example, a floor constructed by laying floor stone on a concrete slab, and includes, for example, floor stone, bonding material, and base material.

[0020] The "permeation method" is a method of permeating a penetrating water absorption inhibitor into floor stones used in a floor stone installation structure.

[0021] In the following embodiments, a floor stone installation structure and a penetration method will be described.

[0022] [II] Specific details of the embodiment Next, specific details of the embodiment will be described.

[0023] (Other slab structures) First, another slab structure, which is a conventional slab structure, will be described.

[0024] Fig. 1 is a side cross-sectional view of another slab structure. In each figure, the Z axis indicates the vertical direction, +Z indicates the upward direction, and -Z indicates the downward direction. In Fig. 1, only a part of another slab structure 900 is shown, and the detailed structure is not shown (the same applies to Fig. 2).

[0025] Another slab structure 900 in FIG. 1 is a conventional structure that functions as a floor, and includes, for example, a concrete slab 91, a base material 92, a binder 93, and floor stones 94.

[0026] In this other slab structure 900, for example, Basamol was used as the base material 92, and for example, noro was used as the binder 93, and for the floor stone 94, one that had not been impregnated with a penetrating water-absorption inhibitor was used.

[0027] "Basamol" is, for example, an admixture made by mixing cement and sand, and "noro" is, for example, cement or lime dissolved in water.

[0028] In the case of such other slab structures 900 that have been used conventionally, for example, after the upper surface of the other slab structure 900 (i.e., the upper surface (+Z direction) of the floor stone 94) becomes wet with water (rainwater or other liquid) and dries, a wet color appears on the upper surface of the other slab structure 900 (this is not limited to the above case).

[0029] As a result of experiments or simulations, the inventors of the present application have come to the conclusion that when moisture adheres to the upper surface (+Z direction) of another slab structure 900, at least a portion of the moisture penetrates into the floor stone 94, binder 93, and base material 92, and after a certain period of time, the penetrated moisture is absorbed toward the floor stone 94 (+Z direction), or that moisture that has penetrated into the interior of another slab structure 900 from elsewhere is absorbed toward the floor stone 94 (+Z direction), which may be the cause of the wet color.

[0030] (composition) Next, the configuration of a slab structure according to this embodiment will be described. Fig. 2 is a side cross-sectional view of the slab structure according to this embodiment. The slab structure 100 in Fig. 2 is a structure that functions as a floor including a floor stone installation structure, and includes, for example, a concrete slab 11, a base material 12, a binder 13, and floor stones 14.

[0031] For example, the base material 12, the bonding material 13, and the floor stone 14 may be interpreted as corresponding to the "floor stone installation structure," or alternatively, these components plus the concrete slab 11 may be interpreted as corresponding to the "floor stone installation structure."

[0032] (Composition - Slab structure - Concrete slab) The concrete slab 11 in FIG. 2 is a fundamental component of the slab structure 100 and is made of, for example, concrete.

[0033] (Configuration - Slab structure - Base material) The base material 12 in Figure 2 is a component that functions as a base for the slab structure 100, and is provided, for example, to adjust the height, horizontality, inclination, etc. of the upper surface (+Z direction) of the slab structure 100. The base material 12 is provided, for example, between the concrete slab 11 and the floor stone material 14.

[0034] The specific materials constituting the base material 12 are arbitrary as long as they can prevent the occurrence of wet color on the upper surface of the slab structure 100 (i.e., the upper surface (+Z direction) of the floor stone 14), and can be determined, for example, by conducting experiments or simulations (the same applies to the binder 13 and the floor stone 14). Specific materials etc. for the base material 12 will be described later.

[0035] It should be noted that "preventing the occurrence of wet color" may be interpreted as meaning, for example, that the occurrence of wet color is prevented completely, or that the degree of wet color that occurs (the area over which the wet color occurs, the intensity of the wet color, etc.) is reduced to a certain degree or more compared to the degree of wet color that occurs in other conventional slab structures 900 (Figure 1).

[0036] (Construction - Slab structure - Binder) The binder 13 in Fig. 2 is a component provided between the concrete slab 11 and the floor stone 14, specifically, it is provided between the floor stone 14 and the base material 12, and it fixes and bonds the floor stone 14 to the base material 12 (i.e., the concrete slab 1 side). Specific materials for the binder 13 will be described later.

[0037] (Configuration - Slab structure - Floor stone) The floor stones 14 in Fig. 2 are components that form the upper surface (+Z direction) of the slab structure 100, and are formed, for example, by laying a large number of flat floor stones of a predetermined size (flat floor stones 140 (Fig. 6) impregnated with a penetrating water-absorption inhibitor, described later) horizontally. Specific details of the floor stones 14 will be described later.

[0038] (Configuration - Slab structure - Details) Next, the base material 12, the binder 13, and the floor stone material 14 will be described in detail.

[0039] ===Base material, bonding material=== Fig. 3 is an explanatory diagram of the base material and the binder. In Fig. 3, "numbers" = "1" to "5" exemplify materials that can be used as the base material 12 and the binder 13 of this embodiment. These materials can be selected by conducting experiments or simulations to prevent the occurrence of the wet color, taking into consideration the possibility that they may be the cause of the above-mentioned wet color.

[0040] As the materials for the base material 12 and the binder 13, the combinations (patterns 1 to 5) shown by "numbers" = "1" to "5" in FIG. 3 can be used.

[0041] =Pattern 1= For example, as shown by "number" = "1" in Fig. 3, water glass may be used as the binder 13, and glass particles (also referred to as "glass particle material") may be used as the base material 12. In this case, the binder 13 may be interpreted as corresponding to the "first binder."

[0042] It should be noted that "water glass is used as the binder 13" may be interpreted as indicating that water glass is used as the main material of the binder 13 (a material related to the features of the present application). The same applies to similar expressions relating to other components (such as "glass particles are used as the base material 12").

[0043] As the water glass used as the binder 13, for example, sodium silicate No. 3 may be used.

[0044] Any glass particles can be used as the base material 12 as long as they have a lower moisture content (i.e., less moisture content) than the sand contained in the Basamol base material 92 (FIG. 1), and other properties may be the same as those of the sand. In particular, if the moisture content of the sand in the Basamol base material 92 (FIG. 1) is about 14.7%, glass particles with a moisture content of about 1.9% may be used as the base material 12.

[0045] More specifically, the glass particles used as the base material 12 are hardened with a predetermined hardener during construction of the slab structure 100. This predetermined hardener may be a known hardener, but it may also be, for example, a hardener containing a derivative of an organic acid and a higher alcohol, or a hardener containing finely powdered blast furnace slag as its main component.

[0046] =Pattern 2= For example, as shown by "Number" = "2" in Fig. 3, a mixture containing blast furnace slag, water glass, and water may be used as the binder 13, and glass particles may be used as the base material 12. In this case, the binder 13 may be interpreted as corresponding to the "second binder." The glass particles are the same as those in Pattern 1 ("Number" = "1" in Fig. 3) (the same applies to Patterns 3 to 5).

[0047] Fig. 4 is a diagram illustrating the mass ratio of each material. The blast furnace slag contained in the admixture used as the binder 13 is, for example, a mixture of non-iron components such as silica contained in iron ore and ash from the coke used as a reducing agent, combined with limestone, an auxiliary material. Since its specific gravity is smaller than that of pig iron and it lies on top of the pig iron in a molten state, it can be easily separated and recovered. For example, ground blast furnace slag (BFS) 4000 (density 2.91 g / cm3, fineness 4240 cm2 / g) may be used as this blast furnace slag.

[0048] The water glass contained in the mixture used as the binder 13 may be, for example, sodium silicate No. 2 (density 1.50 g / cm 3 , solid content 44%).

[0049] The blending ratio of blast furnace slag, water glass, and water contained in the admixture used as the binder 13 may be one corresponding to "numbers" "1" to "6" shown in Fig. 4. That is, for example, as shown by "number" "1," the blending ratio may be 100:36:24.

[0050] In addition, Figure 4 also shows a column for "glass particles," and the glass particles used as the base material 12 may be used in a mixing ratio corresponding to the information shown in this column, or may be used in other configurations as long as they comply with the contents described in Pattern 1 (i.e., the glass particles do not have to correspond to the information shown in Figure 4).

[0051] <Variations> When a mixture containing blast furnace slag, water glass, and water is used as the binder 13, the binder 13 (i.e., the mixture containing blast furnace slag, water glass, and water) also functions as the base material 12, so the base material 12 may be omitted. When configured in this manner, the slab structure 100 in FIG. 2 comprises a concrete slab 1, binder 13, and floor stone 14, and the floor stone 14 is directly bonded to the concrete slab 1 by the binder 13.

[0052] =Pattern 3= For example, as shown in "Number" = "3" in Fig. 3, a mixture containing blast furnace slag and water may be used as the binder 13, and glass particles may be used as the base material 12. In this case, the binder 13 may be interpreted as corresponding to the "third binder." The blast furnace slag is the same as that in Pattern 2 ("Number" = "2" in Fig. 3).

[0053] =Pattern 4= For example, as shown by "number" = "4" in Fig. 3, a mixture containing alumina cement and water may be used as the binder 13, and glass particles may be used as the base material 12. In this case, the binder 13 may be interpreted as corresponding to the "fourth binder."

[0054] =Pattern 5= For example, as shown by "number" = "5" in FIG. 3, a mixture containing ordinary Portland cement and water may be used as the binder 13, and glass particles may be used as the base material 12.

[0055] FIG. 5 is a diagram illustrating the mass ratio of each material.

[0056] The mixing ratio of ordinary Portland cement and water contained in the admixture used as the binder 13 may be one corresponding to "numbers" 1 to 4 shown in Fig. 5. That is, for example, as shown by "number" 1, a mixing ratio of 135:451 may be used.

[0057] In addition, Figure 5 also shows a column for "glass particles," and the glass particles used as the base material 12 may be used in a mixing ratio corresponding to the information shown in this column, or may be used in other configurations as long as they comply with the contents described in Pattern 1 (i.e., the glass particles do not have to correspond to the information shown in Figure 5).

[0058] ===Floor stone=== Figure 6 is a side cross-sectional view of a flat floor stone when it has been impregnated with a penetrating water-absorption prevention agent. The flat floor stone 140 is a component that constitutes the floor stone 14 in Figure 2, and is, for example, a flat plate member of a predetermined size and shape. The floor stone 14 can be constructed (formed) by laying a large number of these flat floor stones 140 side by side horizontally. The material of the flat floor stone 140 itself (i.e., the material before the penetrating water-absorption prevention agent has been impregnated) is arbitrary, and a known material (similar to that of the conventional floor stone 94 in Figure 1) can be used.

[0059] A "penetrating water-absorption inhibitor" is a solvent that penetrates into an object (e.g., floor stone) and reduces the water absorption of the object. For example, an aqueous silane-based solvent may be used, or other known solvents may be used.

[0060] In this embodiment, unlike the conventional floor stone 94, the floor stone 14 is constructed using flat floor stone 140 that has been impregnated with a penetrating water-absorption inhibitor. In other words, the floor stone 14 in Figure 2 is impregnated with a penetrating water-absorption inhibitor. With this configuration, if moisture adheres to the surface of the slab structure 100, it is possible to prevent the moisture from penetrating into the interior of the slab structure 100 through the floor stone 14.

[0061] (Infiltration method) Next, a method for impregnating the penetrating water absorption prevention agent into the flat floor stone 140 will be described. In the impregnation method, a permeation step is carried out.

[0062] In the permeation step, as shown in Fig. 6, the flat bed stone 140 is placed inside a storage tank 200 in which the penetrating water-absorption prevention agent solution 21 is stored, and the flat bed stone 140 is immersed in the penetrating water-absorption prevention agent solution 21 and left for a certain period of time, thereby allowing the penetrating water-absorption prevention agent to permeate the flat bed stone 140. This completes the permeation method.

[0063] The penetrating water-absorption prevention agent solution 21 is a solution of a penetrating water-absorption prevention agent, and may be, for example, a solution with a concentration of about 30% using any liquid such as acetone or hexane as a solvent, or a solution with another concentration.

[0064] The period of time for which the solution is left standing is arbitrary, but may be, for example, about 1 to 7 days, or about 12 to 24 hours, or another period of time, taking into consideration the concentration of the penetrating water-absorption prevention agent solution 21.

[0065] More specifically, the infiltration step may be performed by placing the flat floor stone 140 on a support 201 provided at the bottom of the storage tank 200. By configuring in this way, it becomes possible to infiltrate the penetrating water-absorption prevention agent from the underside (-Z direction) of the flat floor stone 140 as well.

[0066] The configuration of the support portion 201 is arbitrary, but for example, from the viewpoint of reducing the contact area with the underside (-Z direction) of the flat floor stone 140, a tapered shape may be adopted in which the horizontal cross-sectional area decreases as it moves upward (+Z direction).

[0067] 6, the entire flat floor stone 140 may be immersed in the penetrating water-absorption prevention agent solution 21. By configuring it in this way, it becomes possible to allow the penetrating water-absorption prevention agent to penetrate the entire outer surface of the flat floor stone 140.

[0068] 6, the liquid level of the penetrating water-absorption prevention agent solution 21 may be adjusted so that it is between the upper surface (+Z direction) and the lower surface (-Z direction) of the flat floor stone 140 in the vertical direction (Z-axis direction) of the flat floor stone 140, and only a portion (lower portion) of the flat floor stone 140 may be immersed in the penetrating water-absorption prevention agent solution 21. By configuring in this way, the amount of penetrating water-absorption prevention agent solution 21 used can be reduced, which makes it possible to reduce costs.

[0069] <Variations> As a variation, a drying step may be performed before the permeation step. The drying step is a step in which the flat floor stone 140 is dried using a predetermined drying method (such as a method using an oven or a burner) before the penetrating water-absorption inhibitor is permeated. By performing the drying step in this way, it is possible to promote the permeation of the penetrating water-absorption inhibitor into the flat floor stone 140 in the permeation step.

[0070] (Construction method) Next, we will explain the construction method for the slab structure 100. In this construction method, first to third steps are carried out.

[0071] ===Step 1=== In the first step, a base material 12 is laid on the upper surface (+Z direction) of the concrete slab 11 in FIG. 2. For example, glass particles used as the base material 12 are laid, and then the laid base material 12 made of the glass particles is hardened using a predetermined hardener. In this case, as shown in FIG. 2, the hardened base material 12 is placed on the concrete slab 1. Note that, for example, the glass particles may be mixed with a predetermined hardener, and then the mixed glass particles and predetermined hardener may be laid on the upper surface (+Z direction) of the concrete slab 11.

[0072] ===Second Step=== In the second step, the bonding material 13 is provided on the upper surface (+Z direction) of the base material 12 .

[0073] ===Third Step=== In the third step, a large number of flat floor stones 140, which have been permeated with the penetrating water-absorption prevention agent using the permeation method described above, are placed horizontally on the upper surface (+Z direction) of the binder 13, thereby providing a floor stone 14 made up of a large number of flat floor stones 140. In this case, the floor stones 14 are bonded and fixed to the hardened base material 12 (i.e., the concrete slab 1 side) by the binder 13. This completes the construction method.

[0074] (Prevents wet color from occurring) Next, prevention of wet color generation in the slab structure 100 of FIG. 2 will be described.

[0075] For example, if moisture adheres to the upper surface (+Z direction) of the slab structure 100, the water absorption of the floor stone 14 is reduced by the penetrating water absorption prevention agent in the floor stone 14, so the amount of the adhered moisture that penetrates into the inside of the slab structure 100 is reduced, making it possible to prevent the occurrence of wet colors caused by the moisture.

[0076] Furthermore, for example, with regard to moisture inside the slab structure 100, the moisture content of the base material 12 is relatively low, making it difficult for the moisture to be absorbed, and the moisture is difficult to be absorbed toward the floor stone 94 (+Z direction), making it possible to prevent the occurrence of wet colors caused by the moisture.

[0077] Furthermore, for example, with regard to moisture inside the slab structure 100, the binder 13 is less permeable to moisture than the conventional binder 93 (Figure 1) and is less likely to absorb water, making it possible to prevent the occurrence of wet colors caused by the moisture.

[0078] (Effects of this embodiment) According to this embodiment, the binder 13 is a first binder, a second binder, a third binder, or a fourth binder, and the first binder is a binder containing water glass, the second binder is a binder containing blast furnace slag, water glass, and water, the third binder is a binder containing blast furnace slag and water, and the fourth binder is a binder containing alumina cement and water.This makes it possible, for example, to inhibit the movement of moisture from the inside of the slab structure 100 to the floor stone 14 side, thereby preventing the occurrence of wet color in the slab structure 100.

[0079] The structure further includes a base material 12 that is placed between the concrete slab 1 and the floor stone 14. The base material 12 contains glass granules, which can, for example, inhibit the movement of moisture from the inside of the slab structure 100 to the floor stone 14 side, thereby making it possible to prevent the occurrence of wet color in the slab structure 100.

[0080] In addition, by providing a base material 12 that contains glass granules, it is possible to inhibit the movement of moisture from the inside of the slab structure 100 to the floor stone 14 side, thereby making it possible to prevent the occurrence of wet color in the slab structure 100.

[0081] Furthermore, by allowing the penetrating water-absorption prevention agent to penetrate the floor stone 14, it is possible to inhibit the absorption of moisture through the floor stone 14 into the interior of the slab structure 100, thereby preventing the occurrence of wet color in the slab structure 100. Furthermore, by immersing at least a portion of the flat floor stone 140 that constitutes the floor stone 14, the penetrating water-absorption prevention agent is allowed to penetrate the floor stone, thereby making it possible to easily and reliably penetrate the penetrating water-absorption prevention agent, for example.

[0082] In addition, by immersing the entire flat floor stone 140 that constitutes the floor stone 14 in a solution of the penetrating water-absorption inhibitor, it is possible, for example, to quickly and reliably penetrate the penetrating water-absorption inhibitor.

[0083] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be arbitrarily modified and improved within the scope of the technical ideas of each invention described in the claims.

[0084] (Infiltration method) In the above embodiment, the flat floor stone 140 is immersed in the penetrating water-absorption prevention agent solution 21 as shown in Fig. 6, but the present invention is not limited to this. For example, the penetrating water-absorption prevention agent may be applied to the flat floor stone 140 using an application tool such as a spatula, thereby allowing the penetrating water-absorption prevention agent to penetrate.

[0085] (Regarding flat stone flooring) In the above embodiment, the floor stone 14 in Fig. 2 is constructed using flat floor stone 140 that has been impregnated with a penetrating water-absorption inhibitor, but this is not limited to this. For example, it may be constructed using flat floor stone that has not been impregnated with a penetrating water-absorption inhibitor. In other words, for example, the floor stone 14 in Fig. 2 may be constructed in the same manner as the conventional floor stone 94 (Fig. 1).

[0086] (Omission of base material) Also, in the case of pattern 2 ("number" = "2") in Figure 3, if the base material 12 is omitted, the slab structure can be constructed by providing a binder 13 on the upper surface (+Z direction) of the concrete slab 11 and then providing floor stone material 14 on the upper surface (+Z direction) of the binder 13.

[0087] (About the materials) Furthermore, the materials of the base material 12 and the binder 13 described in the above embodiment may be changed as desired within the range that allows preventing wet coloration, for example, the water glass used as the binder 13 may be something other than sodium silicate No. 2 or sodium silicate No. 3, or sodium silicate No. 2 and sodium silicate No. 3 may be used interchangeably in each pattern (i.e., only one of these two types may be used), or a mixture of these may be used. Note that the material of the binder 13 may also be changed as appropriate. [Explanation of symbols]
