Description

  The present invention relates to a moisture releasing wall surface structure having a function of moisture release and heat insulation and a tile used for the moisture releasing wall surface structure.

The wall of the building is laid with decorative panels and tiles for aesthetic appearance, heat insulation, heat insulation or waterproofing. Alternatively, paint is applied. However, since these panels, tiles, and paints block moisture that should be released from the wall body, there is a problem that moisture is trapped in the room.
For this reason, a single or a plurality of moisture collection spaces that are formed by digging into the interior surface of the foamed resin panel and each moisture collection space that is provided so as to communicate with the moisture collection space and the exterior surface are provided. For example, a moisture-releasing outer heat insulation panel provided with a moisture-releasing hole having a ventilation resistance as large as possible is disclosed (for example, see Patent Document 1). Further, a moisture-permeable paint (see, for example, Patent Document 2) is also disclosed.

  Although such a panel can be said to be effective in terms of moisture release, there are concerns about durability due to the use of a resin and resistance to breakage due to impacts from the outside. In addition, such panels and paints are not easy to express the heavy appearance of tiles.

The bonding portion 14 is a portion where the groove 8 on the back surface of the tile 4 is not formed. FIG. 4 is a cross-sectional view in a direction orthogonal to the extending direction M of the groove 8.

  FIG. 5 shows a cross-sectional shape of tiles (4-3, 4-4, 4-5, 4-6, 4-7) of another embodiment used in the present invention.

  FIG. 6 shows a tile 4-7 in another mode laid on the construction surface 12 of the wall body 10. FIG. The tile 4-7 is adhered to the construction surface 12 by the adhesive 16 at the adhesion portion 14 and is engaged through an engagement portion 18 provided on the construction surface. The engaging portion 18 has a hook shape and engages with the surface of the groove 8-1 of the tile 4-7.

  In the moisture releasing wall surface structure 2 or the moisture releasing wall surface structure 2 'of the present invention, if the tile 4 is described as an example, it is emitted from the wall body 10 in the direction of arrow A as shown in FIG. After moisture reaches the inner space 20 where the groove 8 is located, the gap 15 (see FIG. 15) that becomes the joint space from the opening 24 of the hole 21 (inner space 20) surrounded by the construction surface 12 and the inner surface 22 of the groove 8 Released to the atmosphere via 1). The inner space 20 is composed of a defect space 88. The defect space 88 is electrically connected to the external space by the main side surfaces 6 and 6, and the auxiliary side surfaces 7 and 7 and the tile surface 90 are not electrically connected to the external space.

The effect of cooling the tile 44 by the heat radiation from the inner surface 11 is great. This heat dissipation effect is further promoted by the air flow that enters the inner space 20 at the base of the groove 8 from one of the gaps 15 (FIG. 1) and flows out into the atmosphere (outside) through the other gap 15 (FIG. 1). The

  The irregularities 13 may be dot-shaped. Alternatively, it may be a set of ridges extending linearly in one direction, zigzag or meandering. It may be a net-like unevenness. The period of the unevenness is preferably 1 to 20 mm although it depends on the thickness of the tile 44. The height h from the lowest part of the unevenness to the top of the head is preferably 1 to 10 mm.

  FIG. 11 shows the shape of the tile 4a. The tile 4 a has a shape in which the inner space 20 a that is the base of the through hollow portion 102 penetrates the main side surfaces 6 a and 6 a. Further, a through hole 104 extending from the back surface 106 of the tile to the through hollow portion 102 is formed. The through-hole 102 and the through-hole 104 constitute a defect space 88a.

  The through-hole 102 and the through-hole 104 constitute a defect space 88a. The defect space 88a is electrically connected to the external space by the main side surfaces 6a and 6a, and the sub-side surfaces 7a and 7a and the tile surface 90a are not electrically connected to the external space. The main side surface 6a and the sub-side surface 7a are adjacent to each other, and the opposing direction of the main side surfaces 6a and 6a and the opposing direction of the sub-side surfaces 7a and 7a intersect each other.

  FIG. 12 shows a tile 4 a laid on the construction surface 12 of the wall body 10. The tile 4 a is bonded to the construction surface 12 with an adhesive 16 at an adhesive portion 14. The adhesion part 14 is a part in which the through hole 104 on the back surface of the tile 4a is not formed. FIG. 12 is a cross-sectional view in a direction orthogonal to the extending direction M of the through hollow portion 102. The construction surface 12 has an exposed surface 92a exposed to the defect space 88a.

  In the moisture releasing wall surface structure 2a or moisture releasing wall surface structure 2a ′ of the present invention, as shown in FIG. 13, moisture released from the wall body 10 in the direction of arrow A passes through the through hole 104 from the exposed surface 92a. After reaching the inner space 20a at the base of the through hollow portion 102, the air is released into the atmosphere from the opening 24a of the through hollow portion 102 (inner space 20a) via the gap 15 (FIG. 10a) serving as a joint space. Is done. As described above, even in the moisture releasing wall surface structure 2a or the moisture releasing wall surface structure 2a ′ of the present invention, a passage through which moisture released from the wall body 10 is released to the atmosphere is secured. It is prevented from being trapped. Further, the moisture releasing wall surface structure of the present invention has an effect of shielding heat from the outside solar radiation and the like from the room due to the presence of the inner space 20a.

Due to the presence of the unevenness 13a, the surface area of the inner side surface 11a of the through hollow portion 102 can be increased. As a result, the amount of heat released from the inner side surface 11a is increased, and the tile 44a is heated by heat from external solar radiation or the like. Sometimes, the effect of cooling the tile 44a by heat radiation from the inner surface 11a is great. This heat dissipation effect is further promoted by an air flow that enters the inner space 20 at the base of the through hollow 102 from one side of the gap 15 (FIG. 10) and flows into the atmosphere via the other gap 15 (FIG. 10). .

  The unevenness 13a may be dot-shaped. Alternatively, it may be a set of ridges extending linearly in one direction, zigzag or meandering. It may be a net-like unevenness. The period of the unevenness is preferably 1 to 20 mm although it depends on the thickness of the tile 44a. The height h from the lowest part of the unevenness to the top of the head is preferably 1 to 10 mm. The unevenness is preferably a streak extending linearly in the penetration direction of the penetration hollow portion 102 in terms of moldability of the tile substrate.

Where the area of the portion 120 in contact with the wall body 10 (FIG. 13) on the back surface of the tile is S and the area of the opening 122 on the back surface of the tile of the through hole 104 is K, the ratio of K to (S + K) ((K / (S + K)) × 100) is preferably 2 to 90% in order to efficiently release moisture from the wall surface 10 into the atmosphere. When this ratio is less than 2%, the efficiency of releasing moisture into the atmosphere is deteriorated. If this ratio exceeds 90%, S becomes too small, and the bonding strength between the back surface of the tile and the wall body 10 tends to be insufficient.

  A plurality of through holes 104 may be formed per tile as shown in FIG. In the case where there are a plurality of through holes 104, S in the above equation is the sum of the areas of the openings of each through hole.

In the tile (FIG. 18), the defect space 88 b is formed by the through hollow portion 106 and the cut 105. That is, the groove 8 b includes the through hollow portion 106 and the cut 105. At this time, when the area of the portion of the back surface of the tile in contact with the wall body in the laying state is S, and the area of the portion opened to the back surface 106 of the cut 105 (the sum when there are a plurality of through hollow portions and cuts) is C, The ratio of C to (S + C) is preferably 2 to 90% in order to efficiently release moisture from the wall surface into the atmosphere. When this ratio is less than 2%, the efficiency of releasing moisture into the atmosphere is deteriorated. If this ratio exceeds 90%, S becomes too small, and the bonding strength between the back surface of the tile and the wall body tends to be insufficient.

  In addition, the present invention can be carried out in a mode in which various improvements, modifications, and changes are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
