  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.

  In addition, at the boundary between the bathroom wall panel and the washing 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 An elastically deformable cushion material housed inside, and a flexibility that is laminated on the cushion material so as to cover the recess, and is laminated on the upper surface of the edge portion without the cushion material interposed therebetween. A cushioning layer having a water-resistant surface material, a wall-mounted portion on which a wall panel is placed, provided on a portion of the surface material laminated on the edge, and the wall panel And a sealing part for watertightly sealing a gap formed between the surface material and the surface material 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 foam is provided as a cushioning material on the washing floor, a surface material made of a material that satisfies the basic performance of the unit bath, such as water resistance and chemical resistance, is separately required for the surface exposed to the inside of the bathroom. . In a structure in which such a surface material is laminated on the surface side of the cushion material, the user touches the surface material, but the surface is used to make the user feel the function (softness) of the cushion material. The material is required to be flexible. Here, the surface material is preferably formed as a thin layer.

  Surface materials and cushion materials that satisfy the above-mentioned characteristics are difficult to ensure sufficient strength to support the load, and apart from these, there is a base material that is stronger than the surface material and cushion material to support the load. Necessary. That is, it is desirable to have a structure in which at least a base material, a cushioning material, and a surface material 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 wash floor according to the 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 includes a cushion material 4 and a surface material 5 that are softer than the base material layer 1.

  The cushion material 4 is entirely accommodated in the concave portion 2 of the base material layer 1, and is bonded and fixed to the upper surface (bottom surface) of the concave portion 2 with an adhesive such as a double-sided tape. The cushion material 4 is elastically deformable and is made of a foamed material such as urethane. The cushion material 4 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.

  The surface material 5 is laminated on the cushion material 4 and the edge 6 of the base material layer 1 so as to cover the upper surface of the cushion material 4 and the recess 2. The planar size of the surface material 5 is larger than the planar size of the cushion material 4 (longer in both length and width), and the portion of the surface material 5 that protrudes from the cushion material 4 is not interposed through the cushion material 4. Laminated on the upper surface of the edge 6. The surface material 5 is bonded and fixed to the upper surface of the cushion material 4 and the upper surface of the edge portion 6 of the base material layer 1 with, for example, an adhesive.

  The planar size of the surface material 5 is smaller than the planar size of the entire base material layer 1 (formed shorter in both length and width) and larger than the planar size of the recess 2 (formed longer in both length and width). The surface of the surface material 5 is exposed in the bathroom and becomes a surface that is touched by the user or exposed to hot water. The surface material 5 has water resistance, chemical resistance, impact resistance, and the like, and has flexibility that can follow elastic deformation of the lower cushion material 4. Although the surface material 5 is softer than the base material layer 1, the cushioning property (vertical deformation amount) is smaller than that of the cushion material 4, and the surface material 5 is softer than, for example, FRP used for the base material layer 1. FRP can be used and is thinner than the cushion material 4.

  In addition, as shown in FIG. 3, a groove 5b is formed on the surface of the surface material 5 so as to be formed continuously with the drain outlet or drainage groove. The groove 5b functions as a drainage flow path for hot water that flows on the surface of the surface material 5 toward the drainage port. The groove 5b serves as a drainage channel that can allow water to continuously exist without being interrupted to the drain outlet or the drainage channel. By this groove 5b, it becomes possible to dry the washing floor on the next morning without leaving large polka dots on the washing floor. Further, by forming the grooves 5b on the surface of the surface material 5, unevenness is formed on the surface of the surface material 5, and the effect that the washing floor surface is less likely to slip is also obtained.

  In obtaining a laminated structure of the base material layer 1, the cushion material 4 and the surface material 5, they may be welded and fixed to each other by hot molding integrally (insert molding), or the base material layer 1 is molded. After processing, the cushion material 4 is attached to the upper surface (bottom surface) of the concave portion 2 using an adhesive such as double-sided tape, and the surface of the cushion material 4 is surfaced using an adhesive such as double-sided tape. The material 5 may be pasted.

  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.

  If the linear expansion coefficients of the surface material 5 and the base material layer 1 are different, different shearing forces may act on the boundary surfaces of the respective layers when heat is applied, which may cause peeling. In particular, the washroom floor may be placed in an environment of about 65 ° C. during truck transportation, or may be hot water of about 40 ° C. in actual use. As described above, the washing floor is placed in an environment with a large temperature change, and therefore there is a possibility that linear expansion and contraction may occur, and countermeasures are necessary.

  When the surface material 5 and the base material layer 1 are formed of materials having approximate linear expansion coefficients, the shearing force applied to the cushion material 4 sandwiched and bonded between them is the upper surface of the cushion material 4. Since it becomes substantially equal on the lower surface side, it is possible to reduce the possibility of peeling at the boundary surfaces of the layers, which occurs when the cushion material 4 expands and contracts in the horizontal direction.

  Here, a measure for preventing peeling due to linear expansion by keeping the adhesive strength of each layer strong is also conceivable, but according to this embodiment, peeling can be prevented without depending only on the adhesive strength. . Specifically, in the present embodiment, the surface material 5 and the base material layer 1 each employ a material having an approximate linear expansion coefficient, thereby reducing anxiety factors such as peeling due to the difference in linear expansion of each layer. In particular, by making the surface material 5 thinner and softer than the FRP that is widely used as a washroom floor material, the base material layer 1 has the same quality as the surface material 5 and can use the same FRP as before. This is preferable because it is possible. In addition, since soft FRP becomes a hydrophilic material, it is advantageous also for drainage on the floor surface of the washing place.

  The part laminated | stacked on the base material layer edge part 6 in the surface material 5 functions as the wall mounting part 5a in which the wall panel 50 of a bathroom is mounted. That is, the wall panel 50 is installed on the edge 6 of the base material layer 1 with the surface material 5 interposed therebetween.

  At the boundary between the wall panel 50 and the surface material 5, a seal portion 10 is provided that seals a gap formed between them with a sealing material 11 such as silicon or a joint member. 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 placed on the surface material 5. For this reason, the boundary between the surface material 5 and the base material layer 1 is not exposed in the bathroom. In addition, as described above, the surface material 5 is sealed with the sealing material 11 that seals between the wall panel 50 and the surface material 5 without performing a separate water stop treatment at the boundary between the surface material 5 and the base material layer 1. Since the seal between the base material layer 1 is also used, only one sealing material 11 is required, and the boundary between the surface material 5 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 in the vicinity of the peripheral edge portion of the surface material 5 on the outer side from the concave portion 2. Since the surface material 5 of the portion provided with the sealing material 11 is bonded and fixed to the edge 6 of the hard base material layer 1 without the cushion material 4 interposed, even if a load is applied to that portion, the thickness direction Since it does not bend greatly (vertically) and does not bend, it will not be greatly restored upward from a bent (sunk) state. That is, the surface material 5 under the seal portion 10 does not greatly fluctuate up and down. 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.

  In addition, the cushioning material 4 bears most of the cushioning property of the washing floor, and the surface material 5 bears water resistance, softness against skin contact, design, and the like, so that it does not sink as much as the cushioning material 4 even when a load is applied. . The peripheral portion of the surface material 5 that functions as the wall mounting portion 5 a on which the wall panel 50 is placed is directly bonded and fixed on the edge 6 of the base material layer 1 without the cushion material 4 interposed therebetween. Since the load of the wall panel 50 is not applied, the wall panel 50 is not inclined due to the elastic deformation (sinking) of the cushion material 4, and the restoring force of the cushion material 4 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 material 4 in the cushion layer 3 is entirely 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 surface material 5 is laminated on the cushion material 4 and the edge member 23 so as to cover the upper surface of the cushion material 4 and the recess 2. A portion of the surface material 5 that protrudes from the cushion material 4 is laminated on the upper surface of the edge member 23 without the cushion material 4 interposed therebetween. The surface material 5 is bonded and fixed to the upper surface of the cushion material 4 and the upper surface of the edge member 23 with, for example, an adhesive.

  The part laminated | stacked on the edge member 23 in the surface material 5 functions as the wall mounting part 5a in which the wall panel 50 of a bathroom is mounted. That is, the wall panel 50 is installed on the edge member 23 with the surface material 5 interposed therebetween.

  At the boundary between the wall panel 50 and the surface material 5, a seal portion 10 is provided that seals a gap formed between them with a sealing material 11 such as silicon or a joint member. 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.

  Also in the present embodiment, the wall panel 50 is configured to be placed on the surface material 5. For this reason, the boundary between the surface material 5 and the base material layer 1 (the edge member 23) is not exposed in the bathroom. In addition, as described above, the surface material 5 is sealed with the sealing material 11 that seals between the wall panel 50 and the surface material 5 without performing a separate water stop treatment at the boundary between the surface material 5 and the base material layer 1. Since the seal between the base material layer 1 is also used, only one sealing material 11 is required, and the boundary between the surface material 5 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 in the vicinity of the peripheral edge portion of the surface material 5 on the outer side from the concave portion 2. The surface material 5 of the portion where the sealing material 11 is provided is bonded and fixed to the hard edge member 23 without the cushion material 4 interposed therebetween. Therefore, even if a load is applied to the portion, the surface material 5 extends in the thickness direction (vertical direction). Since it does not bend greatly and does not bend, it does not greatly recover upward from a bent (sunk) state. That is, the surface material 5 under the seal portion 10 does not greatly fluctuate up and down. 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.

  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. Structure can be applied.
