  The resin mat 1 serves as a base for laying the tiles 2, and square tile mounting portions 3 that match the planar shape of the tiles 2 are arranged in three rows and three rows. In each tile mounting portion 3, a plurality of vertical bars 4 and horizontal bars 5 are passed in a lattice pattern, and a plurality of through holes 6 are formed in a grid pattern. On two adjacent sides of the resin mat 1, locking pieces 7 for connection for connecting the adjacent resin mats 1 are formed. When connecting a plurality of resin mats 1, the locking pieces 7 are locked to the vertical beam 4 or the horizontal beam 5 of the resin mat 1 to be connected.

  On the back surface side of the resin mat 1, cylindrical leg pieces 8 are formed at lattice portions where the vertical bars 4 and the horizontal bars 5 intersect. The leg pieces 8 allow the drain space 9 of the tile unit 10 for installation. Is formed. The tile 2 is bonded to the upper surface of each tile mounting portion 3 with an adhesive. An epoxy adhesive or the like is used as this adhesive.

  A similar tile unit is also described in Japanese Patent No. 2783127.

  FIG. 4 is a partially broken plan view of the tile unit 50 for flooring disclosed in the patent, FIG. 5 is an exploded perspective view of the tile unit 50 for flooring, and FIG. 6 is a part of the resin mat. A perspective view and FIG. 7 are longitudinal sectional views of a part of the tile unit 50 for installation.

  The resin mat 30 used in the tile unit 50 for placement is a lattice-like member made up of a number of vertical bars 12 and horizontal bars 14, and legs 16 are formed at the intersections of the vertical bars 12 and the horizontal bars 14. Projectingly formed on the back side (upper side in the figure). The resin mat 30 has a size for laying nine (3 × 3 = 9) tiles.

  A ring portion 18 is formed at a portion where the vertical beam 12 and the horizontal beam 14 intersect with each other and the leg 16 is not formed. The ring portion 18 protrudes to the back side by a certain dimension.

  The inside of the ring portion 18 is an adhesive reservoir for injecting and storing an adhesive for fixing the tile 40 and the resin mat 30. The adhesive reservoir is provided as an opening that penetrates the resin mat 30 in the thickness direction as shown in FIG. In order to increase the bonding strength between the cured adhesive and the resin mat 30, the ring portion 18 has a cross-shaped beam shape extending from the crosspieces 12 and 14 as a locking portion for the cured adhesive. Part 20 is provided.

  As will be described later, the adhesive that is filled and solidified in the ring portion 18 and becomes a lump is brought into an engaged state with the beam-like portion 20, and is firmly held against the resin mat 30 by this mechanical engaging action. Is done.

  Four ring portions 18 are provided for the space of one tile.

  The tile unit 50 for placement is manufactured by joining the tile 40 to the resin mat 30.

  In order to bond the tiles 40 to the resin mat 30, the tiles 40 of the specified number (in this case, nine) are aligned in an inverted state. The resin mat 30 is overlaid on the back surface of the tile 22 in an inverted state. Next, the adhesive 28 is injected into the ring portion 18. The adhesive 28 is in direct contact with the back surface of the tile 40. By curing the adhesive 28, the tile 40 is firmly bonded to the resin mat 30. That is, the adhesive 28 is familiar to the tile 40 and adheres strongly. Further, the cured product of the adhesive 28 is firmly integrated with the resin mat 30 by the beam-shaped portion 20. Accordingly, the tile 40 is very firmly bonded to the resin mat 30.

  The resin mat 30 is provided with a hook portion 38 for connecting adjacent laying tile units 50 to each other. The hook portion 38 has a hook shape extending from two adjacent sides of the resin mat 30.

  When the tile unit 10 for laying is laid in a sunny place, especially in the summer, the tile 2 is heated by direct sunlight, and the tile 2 and the resin mat 1 are bonded by the heat. The agent may deteriorate.

  An object of the present invention is to provide a tile unit for installation in which deterioration of an adhesive due to heat of such direct sunlight is prevented (including suppression).

  In the tile unit for laying of the present invention, in the tile unit for laying formed by adhering a tile to the upper surface of a resin mat, at least the upper surface portion of the tile is a low heat conduction portion having fine pores. It is what.

  The specific gravity of the tile is preferably 1.3 to 1.8.

  Further, when the specific gravity of the tile is d and the thickness of the tile is t (mm), it is preferable that t ≧ 21.417d−2.932.

  In the present invention, the tile has a glaze layer on the surface, and the glaze layer may be configured such that the surface is uneven by fine particles present in the glaze layer or below the glaze layer. Good.

  In the present invention, the tile may have a glaze layer on the surface, and the glaze layer may contain hollow particles.

  Further, in the present invention, the tile may have a glaze layer on the surface, and the glaze layer may include an antibacterial material.

  Since the tile unit for laying of the present invention is a low heat conductive portion having at least an upper surface portion having fine pores, even if the tile is irradiated with sunlight, the heat on the upper surface of the tile is transmitted to the lower surface side of the tile. Is suppressed. Thereby, deterioration of the adhesive bonding the tile and the resin mat is prevented.

  The tile preferably has a sufficient heat insulating property and a predetermined strength. For that purpose, the specific gravity of the tile (bulk specific gravity, the same applies hereinafter) is preferably 1.3 to 1.8.

  If t ≧ 21.417d−2.932, the heat insulating property and strength of the tile are sufficiently compatible.

  The tile may or may not be glazed. If it is glazed, it will be prevented that the stockings and socks are caught and torn.

  In the case of a tile with a glaze layer that has been glazed, the surface of the glaze layer may be made uneven by allowing fine particles to exist inside the glaze layer or below the glaze layer. When the surface is uneven as described above, water is sufficiently retained on the tile surface when water is struck on the top surface of the tile unit for laying, and the tile surface can be cooled well. In addition, if the tile surface is uneven, the contact area between the sole of the person riding on the tile unit for placement and the surface of the tile becomes small, and the heat or cold that is sensed by the sole that touched the tile is reduced. Alleviated.

  The glaze layer may contain hollow particles. When the glaze layer contains hollow particles, the thermal conductivity of the glaze layer is lowered and a heat insulating effect is obtained. Moreover, when a glaze layer surface becomes uneven | corrugated surface by containing a hollow particle, there exists an effect similar to the above.

  In the present invention, the glaze layer may contain an antibacterial material. Thereby, the adhesion | attachment etc. of the mold to a glaze layer are prevented (inhibition is included).

  Hereinafter, the present invention will be described in more detail.

  An example of the configuration on the exterior of the tile unit for laying of the present invention is as shown in FIGS. 1-2 and 4-7. However, the number and shape of the tile mounting portions of the resin mats 1 and 30 are not limited to those shown in the drawings, and other ones may be used.

  The tile unit of the present invention has a structural feature in that the heat insulating property of the tile is high.

  That is, in the present invention, a tile having at least an upper surface portion having fine pores and thus having low thermal conductivity is used as the tile. Preferably, the entire tile has fine pores, and the entire tile is porous and has low thermal conductivity.

  The tile preferably has a specific gravity of 1.3 to 1.8, particularly 1.35 to 1.65, particularly 1.4 to 1.7. When the specific gravity is 1.8 or less, the thermal conductivity of the tile is sufficiently low. However, if the specific gravity is less than 1.3, the strength of the tile is insufficient and the tile is easily broken.

  In addition, since the intensity | strength of a tile will increase when the thickness of a tile becomes large, it is preferable to enlarge thickness about a tile with small specific gravity. In the present invention, it is preferable to use a tile that satisfies the relationship of t ≧ 21.417d−2.932 between the specific gravity d and the tile thickness t (mm).

  In order to make a tile with such a low specific gravity porous, a foaming agent such as SiC is added to the raw material at the time of tile production and foamed during firing, or a hollow balloon made of ceramic (for example, alumina balloon, silica balloon, fly For example, a method of blending ash balloon) may be employed.

  This tile may be a glazed tile having a glaze layer, or may be an unglazed tile having no glaze layer. However, if it is a glazed tile, it will be sufficiently prevented that the socks and stockings are caught and torn.

  In the case of a tile having a glaze layer as described above, the surface of the glaze layer may be formed as an uneven surface by dispersing fine particles in the glaze layer or by allowing fine particles to exist between the glaze layer and the tile substrate.

  If the surface of the glaze layer is uneven, when water is sprayed on the tile unit, a water film is formed on the surface of the tile, and a sufficient water spray effect is obtained. Moreover, when the glaze layer surface is an uneven surface, the contact area between the sole and the tile becomes small, and the heat or cold sensed by the sole is alleviated.

  Examples of such fine particles include feldspar, glass particles, silica, alumina, silicate compounds such as aluminum silicate, metal silicon composites, and the like. The average particle size of fine particles (according to JIS sieve) is about 1 to 100 μm, preferably 20 to 50 μm. The blending amount of the fine particles is preferably such that the average roughness Ra of the glaze layer surface is 1 to 50 μm, particularly 1 to 30 μm. When fine particles are dispersed and contained in the glaze layer, the blending amount of the fine particles is preferably about 5 to 30% by weight.

Even when the fine particles are interposed between the glaze layer and the tile substrate to make the surface of the glaze layer uneven, the material of the fine particles is the same as described above. The average particle size is preferably about 1 to 200 μm. The fine particles are supplied by spreading or the like on the tile substrate before being hung, and then hung and fired. In this case, it is preferable that about 0.1 to 1 g of fine particles are present per 100 cm ^{2 of} the tile base surface. The preferred range of the surface roughness of the irregular surface on the surface of the glaze layer is the same as described above.

  In the present invention, an antibacterial material such as silver or titanium oxide may be blended in the glaze layer. This prevents mold from forming on the glaze layer. When titanium oxide is blended, the effect of preventing the adhesion of dirt by the photocatalytic action is also exhibited.

  As an adhesive for bonding the tile to the resin mat, an epoxy adhesive, a modified silicone adhesive, or the like can be used. As a material for the resin mat, a synthetic resin such as polyethylene, polypropylene, nylon, and ethylene-vinyl acetate copolymer (EVA) is preferable.

  Hereinafter, examples and comparative examples will be described.

  Tiles having different specific gravities were bonded to the polyethylene resin mat having the structure shown in FIGS. 1 and 2 with an epoxy adhesive.

  In addition, as a raw material of a tile base material, the formulations A and B of Table 1 were used, and both were mixed in the ratio of A / B ratio of Table 2. Increasing the proportion of A containing SiC reduces the specific gravity of the tile. Molding was dry press molding and firing was 1200 ° C. × 12 Hr.

  The size of the tile was 100 × 100 × 10 mm, and no glazing was performed.

  The thermal conductivity of the tile was measured with a thermal conductivity meter (QTM-DM2 manufactured by Showa Denko KK), and the results are shown in Table 2.

  Further, a sand bag having a weight of 30 kg (specified by BLT10-03) was naturally dropped from the upper 50 cm, and the damage state of the tile was observed. The results are shown in Table 2 as resistance to tile cracking.

  Furthermore, Table 2 shows the results of the four-stage evaluation of the feeling that is difficult to feel hot when the tile surface temperature is about 50 ° C. when touched.

In addition, the evaluation criteria of the difficulty of cracking in Table 2 are as follows.
○: No cracking △: Partial cracking ×: Always crack

  As shown in Table 2, when the specific gravity of the tile is in the range of 1.3 to 1.8, particularly 1.35 to 1.65, the thermal conductivity is low and it is difficult to peel off.
