  ADVANTAGE OF THE INVENTION According to this invention, in the washing floor of the structure which laminated | stacked the base material and the surface material, the drainage property around a drain outlet part is improved, and it suppresses that a residual water (puddle) generate | occur | produces around a drain outlet part. A washroom floor is provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the washroom floor according to the present embodiment includes a base material 1 and a surface material 2, and the surface material 2 is laminated inside the bathroom rather than the base material 1.

  The base material 1 is waterproof so that hot water does not leak out of the bathroom, and is not sufficiently bent or damaged even when subjected to static loads such as bathroom wall panels, ceiling panels, bath chairs, and basins, and dynamic loads of users. For example, it is made of a thermosetting resin such as FRP (Fiber Reinforced Plastic). Or the base material 1 may be formed from what reinforced thermoplastic resin, such as a polypropylene and polyethylene.

  The base material 1 is formed in a shallow bread shape as a whole. The base material 1 includes a drain port portion 5, a surface portion 4 that is inclined downward toward the upper end of the drain port portion 5, and a water return wall portion that rises upward at the outermost edge portion of the surface portion 4. 3.

  The drain port portion 5 is formed in a concave shape having an opening 6 formed at the bottom and leading to a drain trap (not shown), and a standing surface 7 formed in a cylindrical shape on the outer periphery of the opening 6.

  The surface of the surface material 2 is exposed in the bathroom and becomes a surface that is touched by the user or exposed to hot water. Therefore, the surface material 2 is formed of a material that satisfies basic performances required for the surface of the washroom floor in general use of the bathroom, such as water resistance, chemical resistance, abrasion resistance, and impact resistance. The surface material 2 is made of FRP, PVC (vinyl chloride), polypropylene, polyethylene, urethane resin, polyester resin, styrene / polyester / olefin / acrylic, which is thinner and softer than the FRP used for the substrate 1. Various elastomers, EVA, EPDM, rubber (hard) systems such as silicon rubber, or those adjusted to such a degree that sufficient durability can be expected, or composites in which fillers and reinforcing materials are added based on these A material etc. are mentioned as an example.

  The surface material 2 is laminated on the surface portion 4 in the base material 1. A cutout 13 is formed in the surface material 2 so that the drain port 5 is exposed from the surface material 2 in a state where the surface material 2 is laminated on the surface portion 4 of the base material 1.

  The surface portion 4 of the substrate 1 is provided with a drainage gradient so that the drainage port portion 5 is lowest, and when the surface material 2 is laminated on the surface portion 4, drainage along the drainage gradient of the surface portion 4 is performed. A gradient is also formed on the surface material 2. The water (including hot water) on the surface material 2 flows along the drainage gradient, and is collected at the drainage port 5. Further, in the present embodiment, a drainage groove for promoting drainage in combination with the drainage gradient is provided on the surface of the surface material 2.

  As shown in FIG. 2, a plurality of convex portions 11 and a plurality of groove portions 12 are formed on the surface of the surface material 2. Although only a part of the surface of the surface material 2 is shown in FIG. 2, the convex portion 11 and the groove portion 12 are formed over the entire surface of the surface material 2.

  The convex portion 11 has a function of preventing slipping. For example, in the example shown in FIG. 2, the surface of the convex portion 11 is formed in a corrugated shape, thereby further enhancing the antiskid effect.

  A plurality of groove portions 12 are formed, for example, in a lattice shape so as to surround the periphery of the convex portion 11, and each groove portion 12 is continuous without interruption. Through these grooves 12, it is possible to slowly drain the water flowing between the convex portions 11 to the drain port 5 without interruption. The planar layout of the groove 12 is not limited to the lattice shape, and any layout that can slowly drain the water flowing between the convex portions 11 to the drain port 5 without interruption is sufficient.

  When the laminated structure of the base material 1 and the surface material 2 described above is obtained, they may be welded and fixed to each other by hot molding integrally (insert and laminate molding), or molding of the base material 1 After processing, the surface material 2 may be attached to the surface portion 4 using an adhesive such as a double-sided tape.

Next, FIG. 3 shows an enlarged perspective view of a portion provided with the drain port 5 in the washing floor according to the embodiment of the present invention.
4 is a cross-sectional view taken along the line AA in FIG. 3, and FIG. 5 is a cross-sectional view taken along the line BB in FIG.

  As shown in FIGS. 4 and 5, a step is formed in the corner portion that continues from the surface portion 4 of the base material 1 on which the surface material 2 is laminated to the upper end 7 a of the standing surface 7 of the drain port portion 5. A coking part 31 filled with a caulking agent 32 is provided.

  The end portion 14 formed on the surface material 2 so as to surround the drain port portion 5 on the drain port portion 5 side is separated from the upper end 7a of the standing surface 7 of the drain port portion 5 from the radial center of the drain port portion 5. It is shifted to the side. The shift amount (offset amount) a of the end portion 14 of the surface material 2 with respect to the upper end 7a of the standing surface 7 of the drain port portion 5 is, for example, about 1 to 2 mm.

  The end portion 14 of the surface material 2 slightly protrudes from the surface portion 4 of the base material 1 to the caulking portion 31 and covers a part of the coking portion 31 from above. The caulking portion 31 is filled with a caulking agent 32 having a waterproof property such as silicon. Thereby, the clearance gap between the edge part 14 by the side of the drain outlet 5 in the surface material 2 and the base material 1 under it is sealed watertight, and hot water permeates between the layers of the surface material 2 and the base material 1. You can prevent it.

  In addition, a double-sided tape 33 is attached to the vicinity of the caulking portion 31 in the surface portion 4 of the base material 1, and the vicinity of the end portion 14 of the surface material 2 and the base material 1 are bonded and fixed by the double-sided tape 33. A groove for filling the adhesive is formed on the surface portion 4 of the portion further away from the drain port portion 5 than the portion adhered by the double-sided tape 33, and the adhesive 34 is filled in the groove and the surface material 2 and The substrate 1 is bonded and fixed.

  Normally, the drain outlet 5 is covered with a detachable lid 41 during use.

  Here, FIG. 7 shows a cross-sectional view of the vicinity of the portion provided with the drain outlet 5 of the washing floor in the comparative example. FIG. 7 corresponds to FIG. 5 of the present embodiment described above, and the same components are denoted by the same reference numerals.

  In the comparative example shown in FIG. 7, the horizontal position of the end 44 on the drainage port 5 side of the surface material 2 and the upper end 7 a of the standing surface 7 of the drainage port 5 are matched. In this case, at the downstream end 12a of the groove portion 12, the water attracts and aggregates due to the intermolecular force, and the tendency to stay on the surface material 2 becomes strong, and it becomes difficult for water to flow from the inside of the groove portion 12 to the drain port portion 5. . For this reason, residual water (water pool) is likely to be generated around the drain port 5 on the surface material 2.

  On the other hand, in this embodiment, as described above, the end portion 14 of the surface material 2 on the drain port portion 5 side is separated from the drain port portion 5 with respect to the upper end 7a of the standing surface 7 of the drain port portion 5. The position was shifted to the side. Thereby, the water that has flowed to the downstream end 12a (see FIG. 5) of the groove 12 is not only on the surface material 2 but also on the surface of a different material (in this embodiment, for example, on the surface of the caulking agent 32). It becomes easy to exist across. In the comparative example shown in FIG. 7, the end portion of the surface material 2 and the standing surface 7 are substantially perpendicular, but in the embodiment of the present invention shown in FIG. 5, the standing surface 7 and the surface material 2 are seen in plan view. There is a caulking portion 31 between the two ends. Since the surface material 2 is a thin sheet, the water flowing to the end portion of the surface material 2 straddles the coking portion 31. Since the caulking part 31 is obtained by solidifying the liquid agent, the caulking part 31 does not have a right angle like the end part of the surface material 2 and usually hardens in a smooth shape. Therefore, it is connected gently to the standing surface 7 and drainage performance is improved.

  Further, in the present embodiment, the end portion 14 of the surface material 2 on the drain port portion 5 side is formed in a downward inclined surface shape toward the drain port portion 5. This makes it easier for water to flow from the downstream end 12 a of the groove 12 to the drain port 5, and the drainage around the drain port 5 can be further enhanced.

  Furthermore, the surface of the coking portion 31 (the caulking agent 32 filled therein) is also formed in an inclined surface shape so as to be continuous with the inclined surface of the end portion 14 on the drain port portion 5 side of the surface material 2. Moreover, it becomes the inclined surface which continued from the edge part 14 of the surface material 2 to the drain port part 5, and can further improve the drainage property of the drain port part 5 periphery.

  In addition, the surface of the end part 14 of the surface material 2 and the caulking part 31 (coking agent 32) is not limited to the inclined surface shape, and even if it is formed in a curved surface shape, the groove portion is the same as that formed in the inclined surface shape. Accordingly, it is possible to promote the flow of water from the downstream end 12a of the drain 12 to the drain port 5 and to enhance the drainage around the drain port 5.

Further, as shown in FIG. 6, even if the end 24 on the drainage port 5 side of the surface material 2 is substantially perpendicular to the bottom surface of the groove 12, the end 24 of the surface material 2 is connected to the drainage port 5. By shifting the position away from the drain port 5 with respect to the upper end 7a of the standing surface 7, the water flowing to the downstream end 12a of the groove 12 is not only on the surface material 2 but also different from this. It tends to exist over the surface of the material (in this embodiment, for example, on the surface of the caulking agent 32). In the comparative example shown in FIG. 7, the end portion of the surface material 2 and the standing surface 7 are substantially perpendicular, but in the embodiment of the present invention shown in FIG. 6, the standing surface 7 and the surface material 2 are seen in plan view. There is a caulking part 31 between the two ends. Since the surface material 2 is a thin sheet, the water flowing to the end portion of the surface material 2 also straddles the coking portion 31. Since the caulking part 31 is obtained by solidifying the liquid agent, the caulking part 31 does not have a right angle like the end part of the surface material 2 and usually hardens in a smooth shape. Therefore, it is connected gently to the standing surface 7 and drainage performance is improved.
Furthermore, in the structure shown in FIG. 6, a step between the end portion 24 of the surface material 2 and the caulking portion 31 also contributes to weakening the cohesive force of water, causing water to flow down to the drain port portion 5. Make it easier.

  Further, as shown in FIG. 3, the flow of water from the groove portion 12 to the drain port portion 5 is also promoted by forming a notch groove 21 continuous with the groove portion 12 formed in the surface material 2 in the caulking portion 31. The drainage around the drain port 5 can be enhanced. Of course, the notch groove 21 may be continuously formed up to the standing surface 7 of the drain port portion 5.

  In addition, when multiple slope surfaces with different drainage directions are formed on the surface of the washing ground, the water on the surface of the washing ground tends to gather on the ridges formed in a valley shape at the boundary of each slope surface, and most of the water is It flows along the ridgeline or the vicinity thereof and reaches the drain port 5. Therefore, even if the notch groove 21 is not formed at the downstream end of all of the plurality of grooves 12 extending to the drain port 5, the notch groove 21 is formed only at the downstream end of the ridgeline. A sufficient effect can be obtained in suppressing residual water (water pool) around the drain port 5.

  Further, since the plurality of groove portions 12 are formed as a continuous drainage channel network, the groove portion 12 formed near the notch groove 21 even if the downstream end is not directly continuous with the notch groove 21. Downstream water can flow into the cutout groove 21 through the drainage network. As a result, the amount of water remaining on the downstream side of the groove 12 that is not directly continuous with the notch groove 21 can be made extremely small. If the amount of the remaining water is small, it is naturally dried and dried sufficiently by the next day.

  The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to them, and various modifications can be made based on the technical idea of the present invention.

  In the above-described embodiment, the two-layer laminated structure of the base material 1 and the surface material 2 has been described. However, for example, a cushion layer made of a foamed material such as urethane is elastically deformable between the base material 1 and the surface material 2. It is good also as a structure which interposes in and provides cushioning property to a washing-room floor.
