  Generally, the wall panel which comprises the wall surface of a unit bath is mounted in the peripheral part on a washroom floor. However, when the wall panel is placed on the cushion layer for providing cushioning properties, there is a possibility that a problem such as a gap between the wall panels occurs due to the wall panel falling downward with time.

  From such a background, it can be considered that the cushion layer is produced only on the inner wall side of the washing floor, but in that case, it is necessary to accurately measure the size of the cushion layer, There was a problem that the manufacturing method was limited.

In view of the above-described problems, the present invention provides a bathroom in which the position of the wall panel does not change over time even when softness is imparted to the washing floor by laminating a cushion layer on substantially the entire upper surface of the washing floor. The purpose is to provide a washroom floor.

  According to one aspect of the present invention, a hard base material and a cushion layer that is laminated on an upper surface of the base material and elastically deformable in a vertical direction are provided, and the cushion layer has a wall panel placed thereon. A wall-mounted portion and a washing-floor floor portion facing the washing area on the inner side of the wall-mounted portion, and the wall-mounted portion of the cushion layer is formed thinner than the washing-room floor portion. A bathroom washroom floor is provided.

  According to the present invention, a bathroom washroom floor where the position of the wall panel does not change over time even when softness is imparted to the washroom floor by laminating a cushion layer over substantially the entire top surface of the washroom floor. Can be provided.

1st invention in this invention is equipped with the hard base material 10 and the cushion layer 20 laminated | stacked on the upper surface of the base material 10, and can be elastically deformed to a perpendicular direction, and the wall panel 80 mounts the cushion layer 20 in it. The wall mounting part 22 is disposed, and the washing floor part 21 facing the washing place on the inner side of the wall mounting part 22, and the wall mounting part 22 of the cushion layer 20 is thinner than the washing floor part 21. It is the washroom floor 1 for bathrooms characterized by being formed in this.

According to the first invention, the washing floor 21 that is touched by the bather's feet is soft because it is thick, and the wall-mounting portion 22 on which the wall panel 80 is placed is small, so that the wall panel 80 can be removed from the state before the wall panel 80 is installed. Even in the long-term use after the panel 80 is installed, it is possible to provide the bathroom washroom floor 1 with a small amount of vertical deformation. In particular, since the cushion layer 20 can be laminated on the entire washroom floor 1, restrictions on the manufacturing method can be reduced.

2nd invention in this invention is the washroom floor 1 for bathrooms characterized by the wall-mounted part 22 being formed thinly by being compressed.

  According to the second aspect of the invention, the cushion layer 20 formed with a substantially constant thickness can be realized by subjecting only the wall-mounted portion 22 to heat and pressure molding or the like, so that the manufacturing cost can be further reduced.

  In the third aspect of the present invention, the bottom surface of the wall mounting portion 22 in the cushion layer 20 and the bottom surface of the washing ground floor portion 21 are formed flush with each other. It is a washroom floor 1 for a bathroom, which is formed at a position lower than the upper surface.

  According to the third invention, in the state where the wall panel 80 is installed, the upper surface of the washing floor 21 is not drawn into the wall panel 80, so that the water between the end of the washing floor 21 and the front of the wall panel 80 is Became difficult to accumulate.

  According to a fourth aspect of the present invention, the amount of bending in the vertical direction when the same load is applied to the wall mounting portion 22 and the wash floor portion 21 from above is smaller in the wall mounting portion 22. This is a washroom floor 1 for the bathroom.

  According to the fourth invention, the washing floor 21 that is touched by the bather's feet is soft because it is thick, and the wall-mounting portion 22 on which the wall panel 80 is placed is thin. Even in the long-term use after the panel 80 is installed, it is possible to provide the bathroom washroom floor 1 with a small amount of vertical deformation.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded view of a unit bus. The unit bath includes a washing floor 1, a bathtub 2 disposed adjacent to the washing floor 1, a bath apron (not shown) covering the opening between the washing floor 1 and the bathtub 2, and a bathtub of the washing floor 1. By the wall panel 80 mounted on the wall mounting portion 22 formed on the three sides excluding the two sides and on the three sides excluding the washing floor 1 side of the bathtub 2, and the ceiling panel 7 attached to the upper portion of the wall panel 80, A watertight and airtight space is formed.

As shown in FIGS. 2 and 3, the bathroom washing floor 1 in the present embodiment has a two-layer structure including a base material 10 and a cushion layer 20. The base material 10 includes a flat surface portion 11 having an upper surface formed in a flat shape, and a water return portion 12 formed upward at an end portion of the flat surface portion 11, and the flat surface portion 11 and the water return portion 12 are It is integrally formed. Further, the base material 10 is waterproof so that hot water does not leak out of the bathroom, and does not bend or break even when subjected to static loads such as wall panels 80, ceiling panels 7, bath chairs, and basins, and dynamic loads of users. It is formed from a hard material having sufficient strength. For example, it is made of a thermosetting resin such as FRP (Fiber Reinforced Plastic) or a thermoplastic resin such as polypropylene or polyethylene reinforced.

  The cushion layer 20 is formed of an elastically deformable rubber material, and is laminated on substantially the entire surface of the base portion 10 on the plane portion 11 on the inner side of the water return portion 12. The cushion layer 20 is a skin layer formed slightly hard on the surface on the indoor side, and the skin layer is required for the floor surface of the washing place, such as water resistance, chemical resistance, wear resistance, and impact resistance. Satisfies basic performance (durability).

  For example, the cushion layer 20 is preferably manufactured by being integrally formed with the base material 10 in terms of manufacturing efficiency. In this case, the cushion layer 20 is manufactured in a state where the cushion layer 20 is laminated on almost the entire surface of at least the planar portion 11 of the substrate 10. Further, the wash floor 21 of the cushion layer 20 is formed with a drain gradient toward the drain so that water does not collect on the wash floor 21, and the wall mount 22 of the cushion layer 20 is positioned on the wall panel over time. Is preferably thinner than the washing floor 21 and substantially horizontal.

  Therefore, in the present invention, only the portion (wall mounting portion 22) on which the wall panel 80 is placed on the cushion layer 20 is heated and pressed to be sufficiently compressed so that the thickness is reduced. On the other hand, the wash floor portion 21 on which the wall panel 80 that is not heated and pressed is not placed has a sufficient cushioning property because it remains thick. As described above, according to the present invention, the wall-mounted portion 22 of the cushion layer 20 is thinned, and the washing floor portion 21 is thickened so that the cushion layer 20 is laminated on substantially the entire upper surface of the washing floor 1 to thereby form the washing floor 1. Even when softness is imparted, the bathroom washroom floor 1 in which the position of the wall panel 80 does not change with time is realized.

  FIG. 4 shows a comparative example for explaining the problem of the present invention. The washing floor 101 shown in FIG. 4 is formed by laminating a cushion layer 120 having a constant thickness on substantially the entire surface of a flat surface on the base 110. In this case, since the wall panel 80 is placed on the portion having cushioning properties, the cushion layer 120 of the portion on which the wall panel 80 is placed is compressed with time, and the wall panel 80 is lowered downward. There is a risk of falling. Since the wall panel 80 is a part of a structure for forming a water-tight and air-tight unit bath space, a drop in the position of the wall panel 80 over time leads to a change in internal dimensions. In addition, since the gap is a factor, water tightness and air tightness may be affected. Moreover, since the upper surface of the cushion layer 120 in the vicinity of the portion on which the wall panel 80 is placed is also drawn by the fall of the wall panel 80, there is a possibility that a gradient is generated in a direction opposite to the drainage gradient of the washing floor 101. . In this case, there is a possibility that residual water may be generated in a portion where the wall panel 80 is placed, which is not preferable.

  On the other hand, according to the present invention, since the thickness of the wall mounting portion 22 is reduced in advance when the wall panel 80 is not mounted, the wall mounting portion 22 of the cushion layer 20 is installed on the wall panel 80. Before and after, the amount of deformation in the vertical direction becomes extremely small. That is, the position of the wall panel 80 is fixed. As a result, the position of the wall panel 80 does not change over time even when softness is imparted to the washing floor 1 by laminating the cushion layer 20 on substantially the entire upper surface of the washing floor 1. It became possible to provide the washroom floor 1.

  Further, by increasing the foaming ratio of the cushion layer 20, the cushioning property can be further improved. When the cushion layer 20 having a high cushioning property is used, the front surface of the wall panel 80 and the wash floor portion 21 of the cushion layer 20 are used. It can also serve as a seal between the peripheral edge portions.

  Further, by laminating the end portion of the cushion layer 20 so as to extend to the upper end of the standing surface of the water return portion 12, it is possible to prevent water from entering between the cushion layer 20 and the base material 10. If water does not enter between the base material 10 and the cushion layer 20, there is an advantage that the cushion layer 20 gets wet and the cushioning property is deteriorated, and mold may not be generated.
