Description

  The present invention relates to a tile used for the purpose of cooling a wall surface using the heat of vaporization of water and a wall surface structure using the tile.

  In order to prevent an increase in indoor temperature in the summer and to suppress an increase in cooling energy, which is one of the causes of global warming, there is a need to improve the heat insulation of the walls. A tile that has improved heat insulating properties can be cited as meeting this purpose. Specifically, tiles made of a porous material (for example, see Patent Document 1) and tiles having plants vegetated on the surface (for example, see Patent Document 2) are known.

When a tile made of a porous material is used to obtain an excellent heat shielding property, most of the tile is occupied by the porous material, so that there is a possibility that the tile may be lost due to a decrease in strength. Tiles with vegetation on the surface require limited maintenance of the vegetation, so the range of use is limited.

  In view of the above problems, the inventor of the present invention has considered that the use of the heat of vaporization of water is effective for shielding the wall surface. An object of the present invention is to provide a tile used for the purpose of cooling a wall surface using the heat of vaporization of water and a wall surface structure having an excellent heat shielding effect using the tile.

  The gist of the present invention is that it comprises a water-impermeable substrate body and a water retention layer made of a porous body formed on the surface of the substrate body, and the surface of the water retention layer is a tile when laid on a wall surface. The wall cooling tile is the surface.

  The water retention layer may be made of a ceramic porous body.

  The wall surface cooling tile may have a through-hole that opens at a pair of opposite end surfaces.

  The wall surface cooling tile may include a mounting unit that is detachably mounted on the laying wall surface.

  Further, the gist of the present invention resides in a wall surface structure in which the wall surface cooling tiles are laid.

  The wall surface structure may include water supply means for supplying water to the tile surface of the wall surface cooling tile.

  The wall structure may include a mooring device for mooring a vine plant stem.

  The anchoring tool may include a bar-like member that is stretched substantially horizontally with a space from the tile surface of the wall surface cooling tile.

The anchoring portion can be fixed to one end portion of the support portion, and the other end portion of the support portion can enter the gap and be fixed to the substrate.

  Further, the gist of the present invention resides in the wall surface structure in which plants are fixed on the tile surface.

  ADVANTAGE OF THE INVENTION According to this invention, the wall surface structure which has the outstanding heat-insulation effect using the tile for wall surface cooling used suitably for the objective of cooling a wall surface using the vaporization heat of water, and the tile for wall surface cooling is provided. .

  The aspect of the cold wall rejection tile of the present invention will be described. In addition, in this specification, the same code | symbol written over each figure shows the same or similar member and thing. As shown in FIG. 1, the wall surface cooling tile 2 of the present invention includes a water-impermeable substrate body 4 and a water retention layer 6 made of a ceramic porous body formed on the surface of the substrate body 4. When the wall surface cooling tile 2 is laid on the wall surface, the surface of the water retaining layer 6 becomes the tile surface (the front surface of the tile).

  The water retention layer 6 is composed of a porous body having communication holes. When water is brought into contact with the porous body, the contacted water is absorbed through the communication hole and held in the space of the communication hole. The retained water evaporates from the tile surface to the outside through the communication hole, and the wall cooling tile 2 is cooled by the heat of vaporization at that time.

  The material of the substrate body 4 can be the same material as the ceramic used for ordinary tiles. The size of the substrate body 4 is almost the same as that of a normal tile.

It is preferable that the thickness of the water retaining layer 6 is 0.5 to 5 mm. If the water retention layer 6 is too thin, the amount of water retention is insufficient and a good cooling effect cannot be obtained. If the water-retaining layer 6 is too thick, the thickness of the tile becomes excessive, lacks aesthetics, and becomes too heavy. The water retention rate (water absorption weight / dry weight) of the porous body constituting the water retention layer 6 is preferably 120 to 200%. The water absorption weight is a weight after a porous body having a predetermined shape is immersed in water and allowed to stand for 1 minute and then taken out and excessive water is allowed to fall naturally. Moreover, the water retention amount per unit area in the front surface of the wall cooling tile 2 by the water retention layer 6 after such a series of immersion operations is 0.01 to 0.11 g / cm. ² is preferable.

  The water-retaining layer 6 is, for example, a coating layer obtained by applying a slurry containing an aggregate made of coarse-grained ceramic (such as chamotte) such as crushed pieces of earthenware and an agate component made of glass or feldspar to the substrate body 4 and drying it. It can be obtained by firing. Moreover, the composite precursor which formed this coating layer on the surface of the unglazed board which is the precursor of the board | substrate body 4 can be baked, and a cold wall rejection tile can be obtained. The average particle size of the coarse-grained ceramic is preferably 0.1 to 3 mm. The mixing ratio of the coarse-grained ceramic and the soot component is preferably 100: 5 to 100: 80 (weight ratio).

  Alternatively, a composite precursor obtained by laminating a base layer containing a burnt-out granule, a sheet-like material composed of a burnable foam or a fiber aggregate, etc., on the surface of a base plate that is a precursor of the substrate body 4 is integrally fired. Thus, a cold wall rejection tile can be obtained. In this case, the water-retaining layer 6 is formed by burning out the sheet-like material composed of burnable particles, foams, and fiber aggregates by firing.

  The water retention layer 6 may be made of a porous resin. Examples of the porous resin include rigid urethane foam and phenolic resin foam. Alternatively, the water retaining layer 6 may be made of a synthetic fiber felt or a fabric such as a woven fabric. These foams and cloths are molded into a piece according to the shape of the tile, and adhered to the surface of the substrate body 4 with an adhesive to obtain the wall surface cooling tile 2 of the present invention.

  As shown in FIG. 2, the wall surface cooling tile 2 of the present invention is laid on a wall surface 10 to be laid in the same manner as a normal tile laying to form a wall surface structure 12. In the wall surface structure 12, the water retention layer 6 of the wall surface cooling tile 2 absorbs and retains water by watering the wall surface. As the retained water evaporates, the wall surface cooling tile 2 is cooled, and the wall surface structure 12 exhibits a heat shielding effect against external heat caused by sunlight or the like. Thus, the wall surface structure 12 of the present invention has a cooling effect based on the same principle as the cooling effect of so-called water hitting. That is, the wall surface water cooling system can be constructed by the wall surface structure 12 of the present invention.

  Moreover, since the surface of the wall surface cooling tile 2 of the wall surface structure 12 is supplied with water by rain and is retained without being sprinkled by water, a particularly effective cooling effect can be obtained even after rain.

  Furthermore, in this invention, the wall surface structure 12 may be provided with the water supply means 14 which supplies water to the surface of the laid wall surface cooling tile 2, as shown in FIG. The water supply means 14 is provided immediately above the laid wall surface cooling tile 2 and includes a water supply pipe 16 disposed horizontally. The water supply pipe 16 is provided with a plurality of guide holes 18 along the length of the pipe below the pipe wall. The water supplied to the water supply pipe 16 is discharged downward from the guide hole 18 and supplied to the tile surface of the wall surface cooling tile 2. The water supply means 14 may be configured such that water is supplied to the water supply pipe 16 during a time period determined by a timer (not shown). Although the water used for the water supply means 14 may be tap water, it may be purified water purified at home. Furthermore, the stored rainwater may be sufficient. Thus, in the present invention, it is possible to save water by effectively utilizing the water that is originally drained.

  The wall surface structure 12 of the present invention not only wets the wall surface, but also stores a large amount of water on the wall surface by the water retaining layer 6, thereby increasing the heat capacity of the water and obtaining an excellent cooling effect, and the length of time until the water is completely evaporated. The cooling effect can be maintained over time, and simply by making the wall surface uneven or easy to wet, the cooling effect over a long time as in the present invention cannot be obtained.

  In another aspect of the present invention, the wall surface cooling tile may be hollow as shown in FIG. In FIG. 4, the wall surface cooling tile 2 t has a through hole 22 (hollow portion 23) that penetrates the tile so as to open at a pair of opposite end surfaces (end surfaces) 19, 19 of the tile. Due to the presence of the hollow portion, the heat shielding property of the tile is further improved. The hollow portion 23 may be a hermetically sealed hollow portion whose opening is sealed.

  Furthermore, the wall surface structure 12 of the present invention exhibits an excellent function even when the surface of the water-retaining layer 6 causes vine-like plants such as straw (for example, ivy, mushroom, heddle, nuts, etc.) to appear on the wall surface. The wall-cooling tile according to the present invention has a texture in which vine plants are easily adsorbed, and the entire construction surface is always maintained in a substantially constant moisture state by irrigating the tile surface, so that the temperature rise is small. So vine plants are easy to adsorb. In addition, when the wall surface cooling tile has the hollow portion 23 (FIG. 4), the tile surface temperature is unlikely to rise due to the cooling effect, and the vine plant is more easily adsorbed. That is, the wall surface structure 12 of the present invention allows fast growth of climbing plants on the wall surface, is excellent in vegetation-inducing functions, and exhibits a good function of climbing cocoons. For example, a normal brick wall can take 5-6 months to grow a vine plant, whereas the wall structure of the present invention can obtain a similar overgrowth in about 3 months. . In addition, by allowing the vine plant to spread on the wall surface, the cooling effect and light shielding effect of the vine plant can be exhibited together with the cooling effect of the water retaining layer 6 described above, and extremely excellent wall surface cooling. An effect can be obtained.

  Further, in the conventional wall surface where the vine plant is prosperous, there was a trouble that the root of the plant deeply enters the inside of the wall. However, the wall surface structure 12 of the present invention has a water retention layer 6 that serves as a plant scaffold. Since the non-porous substrate body 4 is fixed to the back side of the water retaining layer 6, there is no deep root penetration and an excellent root-preventing effect. .

  In another aspect of the present invention, the wall surface cooling tile may be hollow as shown in FIG. In FIG. 4, the wall surface cooling tile 2 t has a through hole 22 (hollow portion 23) that penetrates the tile so as to open at a pair of opposite end surfaces (end surfaces) 19, 19 of the tile. Due to the presence of the hollow portion, the heat shielding property of the tile is further improved. The hollow portion 23 may be a hermetically sealed hollow portion whose opening is sealed.

  Since the surface of the water retaining layer 6 is more easily soiled by mold or the like than the surface of a normal tile material, in still another aspect of the present invention, a mounting means for mounting the wall cooling tile to the wall surface 10 in a detachable manner. May be provided. By providing the mounting means, damaged or dirty tiles can be easily replaced. FIG. 5 shows an example of the shape of the wall surface cooling tile 2 f that can be detachably attached to the wall surface 10. In FIG. 5, the wall surface cooling tile 2 f is formed by superimposing a water retaining layer 6 f on the surface of a baked object 118 corresponding to a substrate body. A through hole 22 is formed in the baked object 118.

  On the upper surface 111 of the wall surface cooling tile 2f, a protrusion that protrudes upward in the short width direction A of the wall surface cooling tile 2f and extends in the long width direction B (hereinafter referred to as the long width direction) of the wall surface cooling tile 2f. 110 is formed, and a groove 112 extending in the long width direction is formed on the back surface 105 of the wall surface cooling tile 2f. On the inner surface of the grooving 112, an engagement groove 115 is further formed in the long-width direction at the upper corner of the bottom.

  A locking groove 114 extending in the long width direction is formed on the lower surface 109 of the wall surface cooling tile 2f. Further, on the lower surface 109, a water guiding groove 135 is formed so as to extend in the long width direction from the locking groove 114. The protruding portion 120 formed by the formation of the locking groove 114 is missing such that the lower end portion is uniformly scraped in the longitudinal direction, the lower surface 122 of the protruding item 120 is positioned above the lower surface 109, and the hollow space 142 is formed. It occurs at the intersection of the lower surface 122 and the rear surface 105.

  In the wall cooling tile 2f having such a structure, the base body of the fired body 118 is produced by, for example, extruding a cylindrical base body having substantially the same cross-sectional shape as the fired body 118, and then having a predetermined length in the longitudinal direction. Cut into pieces and manufactured.

  FIG. 6 shows a wall surface structure 12 f in which the wall surface cooling tile 2 f is mounted on the wall surface 10.

The plane of one flat strip is arranged in parallel with the plane of the base plate 126, and the other edge along the longitudinal direction of the other flat strip is fixed to the base plate 126. The lower receiving member 128 is composed of another long member in which the long plate is folded in a cross-sectional shape with a crease along its longitudinal direction, and the surface is inclined obliquely upward with the surface of the base plate 126. The base plate 126 is fixed at the edge along the longitudinal direction of the base plate 126.

Specifically, the lower receiving member 128 engages with the locking groove 114 (FIG. 5), and the upper receiving member 129 engages with the engaging groove 115 (FIG. 5). Further, the wall surface cooling tiles 2f are arranged vertically and horizontally along the wall surface 10, and the adjacent upper and lower wall surface cooling tiles 2f are disposed in the depression space 142 of the upper wall surface cooling tile 2f. The ridges 110 of the tile 2f are inserted and combined. A mounting means 60 (engaging portion 82p (FIG. 5)) for mounting the wall surface cooling tile 2f on the construction surface is configured including the locking groove 114 and the engaging groove 115.

  The cross-sectional shape of the lower receiving member 128 and the upper receiving member 129 is not limited to the L shape or the V shape as long as it engages with the locking groove 114 and the engaging groove 115.

  In the wall surface structure 12f, when the plant is fixed on the tile surface, the presence of the substrate 126 can prevent the root of the plant from entering the wall body of the building. The substrate 126 may be a metal plate having a thickness of 1 to 5 mm such as an aluminum plate.

  In addition, in the wall surface structure of the present invention, as shown in FIG. 7, the anchoring device 162 for anchoring the stalk 160 of the vine plant is provided, and the tip part of the stalk 160 of the vine plant has dropped too much. Sometimes, the entire stem from the root to the tip can be prevented from falling due to its own weight. The mooring device 162 includes a mooring portion 167 which is made of a rod-shaped member 164 and is moored in contact with a stalk 160 of a creeping plant and a fixture (not shown). The fixture fixes the mooring portion 167 to the wall surface 10. The anchoring portion 167 composed of the rod-shaped member 164 is stretched substantially horizontally from the tile surface with a predetermined interval wp. This embodiment is preferable because of its simple structure. A plurality of rod-like members 164 may be arranged in the vertical direction of the wall surface 10 with a space therebetween. The rod-shaped member 164 may be installed in an oblique direction or a vertical direction with respect to the ground.

In addition, the shape of the member used for the mooring device 162 may be any shape as long as it can anchor the stem 160 of the vine plant. The mooring part 167 preferably anchors the stalk 160 of the vine plant by receiving the stalk at the time of dropping, but entangles the vine and the stalk when the vine plant grows to prevent the stem from dropping. You may prevent.
