  In general, the cushion layer is difficult to ensure sufficient strength to support a load, and a base material that guarantees the strength to support the load is required separately from the cushion layer. In that case, if water permeates between the base material and the cushion layer, the cushion layer may get wet and the cushioning properties may deteriorate or mold may form.Therefore, seal the periphery of the cushion layer with silicone or joints. It is necessary to seal the material in a watertight manner.

  Also, at the boundary between the bathroom wall panel and the washroom floor, water tightness is secured with a sealing material such as silicone or joints so that water does not enter the back of the wall panel (to prevent water leakage outside the bathroom unit). There is a need to.

  Thus, if a cushion layer is provided on the washroom floor of the bathroom, two seal portions are required. The seal portion is required to be reduced as much as possible because there is a concern that the design property is impaired, the silicon is cut, or the joint is detached.

  This invention is made | formed in view of the above-mentioned problem, and provides the washing-room floor for bathrooms which provides softness to a washing-room floor and requires only one seal part.

  According to one aspect of the present invention, a hard base material layer having a recess, and an edge having an upper surface provided at a position on the outer side of the recess and higher than the upper surface of the recess, the recess A cushion portion that is stacked on the upper surface and accommodated in the recess, and a peripheral portion that is provided on the inner side of the bathroom and stacked on the upper surface of the edge portion, and the deformation amount in the vertical direction is extremely smaller than that of the cushion portion. A cushion layer having water resistance at least on the surface; a wall mounting portion on which the wall panel is placed; and a surface of the wall panel and the cushion layer provided on the peripheral portion of the cushion layer; And a sealing part for watertightly sealing a gap formed between the two with a sealing material.

  ADVANTAGE OF THE INVENTION According to this invention, the washroom floor for bathrooms which provides a softness to a washroom floor and a seal part only needs one place is provided.

  In order to give softness to the washroom floor in the bathroom, it is conceivable to construct the washroom floor with a material having an elastically deformable cushioning property. For example, a foam having a cushioning property is water resistant, chemical resistant, The basic performance required for a washing floor such as impact is not excellent, and it is difficult to provide a washing floor made of only a cushioning material as a product. In addition to foam, there are rubber materials as cushioning materials, but since rubber materials have a rubber odor, such materials are placed in a highly airtight bathroom over a relatively large area such as a washroom floor. It is not preferable to use it.

  Therefore, when the foam is provided as a cushioning material on the washing floor, it is necessary to use a material that satisfies the basic performance of the unit bath such as water resistance and chemical resistance for the surface exposed to the inside of the bathroom.

  The cushion layer configured to satisfy the above-mentioned characteristics is difficult to secure sufficient strength to support the load, and apart from the cushion layer, there is a base material layer that is stronger than the cushion layer to support the load. Necessary. That is, it is desirable to have a structure in which at least the base material layer and the cushion layer are combined in order to ensure the minimum basic performance required for the washing floor while giving softness to the washing floor.

[First Embodiment]
FIG. 1 is a schematic cross-sectional view of a bathroom washroom floor according to a first embodiment of the present invention.

  The washing floor according to the present embodiment includes a hard base layer 1 and a cushion layer 3 having cushioning properties laminated on the base layer 1.

  The base material layer 1 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 50, ceiling panels, bath chairs, and washbasins, and dynamic loads of users. For example, it is made of a thermosetting resin such as FRP (Fiber Reinforced Plastic) or a material obtained by reinforcing a thermoplastic resin such as polypropylene or polyethylene.

  The base material layer 1 is provided with a concave portion 2 formed in a concave shape in a longitudinal sectional view. The concave portion 2 occupies most of the area of the base material layer 1 as viewed from above, and an edge 6 is provided on the outer side of the concave portion 2 so as to be one step higher than the upper surface (bottom surface) of the concave portion 2.

  FIG. 2 is a schematic plan view of the base material layer 1, and a drain pit 15 is formed in a part of the base material layer 1. The edge 6 is provided so as to surround the entire circumference of the recess 2 (including between the recess 2 and the drainage pit 15). A side wall portion 8 that functions as a water return wall rising upward is provided on the outermost side of the base material layer 1 on the outer side of the edge portion 6. Thus, the drain pit 15 is formed on the outer side from the edge 6, and the side wall 8 is formed further on the outer side of the drain pit 15.

  The base material layer 1 is integrally formed by hot-molding a hard material (for example, FRP), and thus the recess 2, the edge 6 and the side wall 8 are integrally formed.

  The cushion layer 3 has cushioning properties, and at least the surface exposed to the inside of the bathroom has water resistance. For example, an in-mold foamed mold body can provide a dense skin layer, and can provide a structure having cushioning properties while imparting water resistance to the surface by the dense skin layer.

  Most of the cushion layer 3 other than the peripheral edge portion 4b inside the bathroom (cushion portion 4a) is accommodated in the recess 2 of the base material layer 1, and is bonded to the upper surface (bottom surface) of the recess 2 with an adhesive such as double-sided tape. Fixed. The cushion part 4a accommodated in the recessed part 2 can be elastically deformed, and is made of a foamed material such as urethane, for example. The cushion layer 3 may be an elastically deformable rubber material, but a foam without a rubber odor is preferable for use as a bathroom floor in a bathroom with high airtightness.

  Since the surface of the cushion layer 3 is exposed in the bathroom and becomes a surface that the user touches or is exposed to hot water, it has water resistance, chemical resistance, and impact resistance, and the elasticity of the lower cushion portion 4a. Flexibility to follow deformation.

  Moreover, as shown in FIG. 3, the groove | channel 3a formed continuously in the surface of the cushion layer 3 at a drain outlet or a drainage ditch | groove is formed. The groove 3a functions as a drainage flow path for hot water that flows on the surface of the cushion layer 3 toward the drainage port. This groove 3a is a drainage channel that allows water to continue to the drain outlet or drainage channel without interruption. By this groove 3a, it becomes possible to dry the washing floor on the next morning without leaving large polka dots on the washing floor. Further, since the groove 3a is on the surface of the washing place, unevenness is formed on the surface of the washing place, and the effect that the washing place floor becomes less slippery is also obtained.

  The peripheral edge 4b provided inside the bathroom in the cushion layer 3 is laminated on the upper surface of the edge 6 of the base material layer 1 without using the cushion 4a. The peripheral edge 4b is bonded and fixed to the upper surface of the edge 6 of the base material layer 1 with, for example, an adhesive.

Since the peripheral edge 4b is thinner than the cushion 4a, the amount of deformation in the vertical direction is extremely small. Specifically, the thickness of the peripheral edge 4b is such that it hardly elastically deforms in the vertical direction (8 cm or less, preferably 5 cm or less, more preferably 2 cm or less), the amount of deformation in the vertical direction when a load of 100 N / cm ² is applied to the peripheral portion 4 b is suppressed to 0.5 mm to 2.0 mm. Thus, the cushion layer 3 having the cushion portion 4a and the peripheral edge portion 4b is formed from a flat surface having a slight drainage gradient of about 1/50 on the surface facing the inside of the bathroom. On the other hand, the cushion part 4a is formed thicker on the back surface than the peripheral edge part 4b.

  In obtaining the laminated structure of the base material layer 1 and the cushion layer 3, they may be welded and fixed to each other by hot molding integrally (insert molding). You may affix the cushion layer 3 with respect to the upper surface (bottom surface) of the recessed part 2 using adhesives, such as a double-sided tape, for example.

  Since the washing floor according to the present embodiment includes the cushion layer 3, a soft touch that does not hurt even if the user kneels can be obtained. In addition, the floor fits in with your feet, making it difficult to slip even with wet feet. Furthermore, for example, even if the basin is dropped on the floor, no sound is heard. Furthermore, it is difficult for the user to feel cold.

  In the cushion layer 3, at least a part of the peripheral edge portion 4 b stacked on the base material layer edge portion 6 functions as a wall mounting portion on which the bathroom wall panel 50 is placed. That is, the wall panel 50 is installed on the edge 6 of the base material layer 1 with the peripheral edge 4b of the cushion layer 3 interposed therebetween.

  At the boundary between the wall panel 50 and the peripheral edge 4b of the cushion layer 3, a seal portion 10 is provided that seals the gap formed between them with a sealing material 11 such as silicon or a joint member. ing. Further, the sealing material 11 prevents water from entering between the cushion layer 3 and the base material layer 1. That is, the sealing material 11 seals in a watertight manner using both the wall panel 50 and the cushion layer 3 and between the cushion layer 3 and the base material layer 1.

  That is, only one seal portion 10 can prevent water from entering the back side of the wall panel 50 to prevent water leakage outside the bathroom unit, and between the base material layer 1 and the cushion layer 3. Intrusion of water can be prevented, and the cushion layer 3 can be prevented from getting wet and the cushioning property from being deteriorated, or mold can be prevented from being generated.

  The sealing material 11 has a problem that the design property of the entire bathroom is impaired, a problem that dirt such as mold adheres to the sealing material 11 and the design property is impaired, and the silicon is cut or the joint member is detached. Therefore, it is necessary to reduce as much as possible.

  In the present embodiment, the wall panel 50 is configured to be placed on the peripheral edge 4 b of the cushion layer 3. For this reason, the boundary between the cushion layer 3 and the base material layer 1 is not exposed in the bathroom. Further, as described above, the cushioning layer 3 and the cushioning layer 3 can be sealed with the sealing material 11 that seals between the wall panel 50 and the cushioning layer 3 without performing a separate water stop treatment at the boundary between the cushioning layer 3 and the base material layer 1. Since the seal between the base material layer 1 is also used, only one sealant 11 is required, and the boundary between the cushion layer 3 and the base material layer 1 is not exposed in the bathroom, so that the appearance is not impaired. Product value can be increased.

  Further, the sealing material 11 is provided on the peripheral edge 4 b of the cushion layer 3 on the outer side of the recess 2. The peripheral portion 4b is bonded and fixed to the edge portion 6 of the hard base material layer 1 without the cushion portion 4a, and the amount of deformation in the vertical direction is much smaller than that of the cushion portion 4a as described above. Even if a load is applied, the film does not bend greatly in the thickness direction (vertical direction) and does not bend, so that it is not greatly restored upward from the bent (sunk) state. That is, the lower part of the seal part 10 does not fluctuate greatly in the vertical direction. Therefore, a large stress that pulls or lifts the sealing material 11 provided in that portion does not act, and the sealing material 11 does not break or come off. As a result, sealing performance and appearance are not impaired.

  Further, since the wall panel 50 is placed on the peripheral edge 4b and the load of the wall panel 50 is not applied to the cushion 4a, the wall panel 50 is inclined or cushioned by elastic deformation (sinking) of the cushion 4a. The restoring force of the portion 4a does not act on the wall panel 50. Thereby, the wall panel 50 and the ceiling panel on it can be stably supported on the base material layer 1, and an undesired gap arises in the joint part between the wall panels 50 or between the wall panel 50 and other members. This can prevent the situation and ensure a stable waterproof property in the bathroom.

[Second Embodiment]
FIG. 4 is a schematic cross-sectional view of a bathroom wash floor according to the second embodiment of the present invention.

  The washing place floor according to the present embodiment also includes the hard base material layer 21 and the cushion layer 3 having cushioning properties laminated on the base material layer 21. In the present embodiment, the cushion layer 3 is configured in the same manner as in the first embodiment described above, but the base material layer 21 is different from that in the first embodiment.

  The base material layer 21 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 50, 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 a material obtained by reinforcing a thermoplastic resin such as polypropylene or polyethylene.

  The base material layer 21 includes a shallow bread-shaped base material portion 22 and an edge member 23 provided separately from the base material portion 22 on the upper surface portion (bottom surface portion) 22 a of the base material portion 22. Have. The edge member 23 corresponds to the edge 6 in the first embodiment, and the edge member 23 is made of a material harder than the cushion layer 3. Further, a side wall portion 24 that functions as a water return wall rising upward is provided at the outermost edge portion of the base material portion 22. The upper surface of the upper surface portion 22a of the base material portion 22 is formed flat, and the edge member 23 is fixedly bonded or welded to the edge portion in the vicinity of the side wall portion 24 on the upper surface.

  A recess 25 is provided inside the edge member 23. The edge member 23 functions as a side wall of the recessed portion 25, and the upper surface of the edge member 23 is made one step higher than the upper surface (bottom surface) of the recessed portion 25.

  The cushion portion 4a of the cushion layer 3 is accommodated in the recess 25, and is bonded and fixed to the upper surface (bottom surface) of the recess 25 with an adhesive such as a double-sided tape. The peripheral edge portion 4b of the cushion layer 3 is laminated and fixed on the upper surface of the edge member 23 without the cushion portion 4a interposed therebetween.

  At least a part of the peripheral edge portion 4b of the cushion layer 3 functions as a wall mounting portion on which the bathroom wall panel 50 is mounted. That is, the wall panel 50 is installed on the edge member 23 of the base material layer 1 with the peripheral edge 4b of the cushion layer 3 interposed therebetween.

  At the boundary between the wall panel 50 and the peripheral edge 4b of the cushion layer 3, a seal portion 10 is provided that seals the gap formed between them with a sealing material 11 such as silicon or a joint member. ing. Further, the sealing material 11 prevents water from entering between the cushion layer 3 and the base material layer 1. That is, the sealing material 11 seals in a watertight manner using both the wall panel 50 and the cushion layer 3 and between the cushion layer 3 and the base material layer 1.

  Further, the wall panel 50 is placed on the peripheral edge 4 b of the cushion layer 3. For this reason, the boundary between the cushion layer 3 and the base material layer 1 is not exposed in the bathroom. Further, as described above, the cushioning layer 3 and the cushioning layer 3 can be sealed with the sealing material 11 that seals between the wall panel 50 and the cushioning layer 3 without performing a separate water stop treatment at the boundary between the cushioning layer 3 and the base material layer 1. Since the seal between the base material layer 1 is also used, only one sealant 11 is required, and the boundary between the cushion layer 3 and the base material layer 1 is not exposed in the bathroom, so that the appearance is not impaired. Product value can be increased.

  The sealing material 11 is provided on the peripheral edge 4b of the cushion layer 3 on the outer side of the recess 2, and the peripheral edge 4b is bonded and fixed to the hard edge member 23 without the cushion 4a. As described above, since the amount of deformation in the vertical direction is extremely smaller than that of the cushion part 4a, even if a load is applied to the peripheral part 4b, it does not bend greatly in the thickness direction (vertical direction), and it does not bend. There is no significant recovery from the bent (sunk) state. That is, the lower part of the seal part 10 does not fluctuate greatly in the vertical direction. Therefore, a large stress that pulls or lifts the sealing material 11 provided in that portion does not act, and the sealing material 11 does not break or come off. As a result, sealing performance and appearance are not impaired.

  Further, since the load of the wall panel 50 is not applied to the cushion portion 4a, the wall panel 50 may be inclined due to elastic deformation (sinking) of the cushion portion 4a, or the restoring force of the cushion portion 4a may act on the wall panel 50. Absent. Thereby, the wall panel 50 and the ceiling panel on it can be stably supported on the base material layer 1, and an undesired gap arises in the joint part between the wall panels 50 or between the wall panel 50 and other members. This can prevent the situation and ensure a stable waterproof property in the bathroom.

  Moreover, in this embodiment, it is not the structure which provided the step in the edge part integrally with the upper surface part (bottom surface part) like the base material layer 1 of 1st Embodiment, but the base material part of a simple shallow bread shape Since the edge member 23 is provided separately from the structure 22, the existing bathroom floor pan can be used as it is without disassembling the existing bathroom unit and replacing the bathroom floor.
