  In order to eliminate the level difference at the entrance / exit of the bathroom and make it easy to enter / exit the bathroom, a slope member may be provided to form a gentle slope from the entrance / exit of the bathroom to the floor of the washroom. In order to prevent water from entering between the slope member and the cushion layer, it is necessary to ensure watertightness between the slope member and the cushion layer with a sealing material such as silicon or a joint member.

  The cushion layer expands and contracts (moves) in the vertical direction when a load is applied from the washing floor, but if the seal part with the slope member expands and contracts in the vertical direction as well, There is a concern that the provided silicon is cut, the joint member is detached, the water tightness is impaired, or the appearance is deteriorated.

  The present invention has been made in view of the above problems, and a sealing material for providing softness to the washing floor and preventing water from entering between the slope member and the cushion layer is used over a long period of time. Provide bathroom washroom floors that do not break or come off.

  According to one aspect of the present invention, a hard base material layer having a recess, and an edge portion provided between the recess and the entrance / exit of the bathroom and having an upper surface at a position higher than the upper surface of the recess. An elastically deformable cushion material accommodated in the recess, and a flexible material that is laminated on the cushion material so as to cover the recess and is laminated on the upper surface of the edge without the cushion material. A cushioning layer having a property and a water-resistant surface material, a slope member provided on the surface of the surface material from the entrance and exit, and water from between the slope member and the surface material. A bathroom washroom floor provided with a seal portion that is watertightly sealed with a sealing material to prevent intrusion, and an end portion of the slope member that is in contact with the surface material is in the surface material. Laminated on the edge Is disposed on the portion, the seal portion, bathroom washing place bed characterized in that it is arranged above the edge of the outer side of the recess is provided.

  Further, according to another aspect of the present invention, a hard part having a recess and an edge having an upper surface provided at a position higher than the upper surface of the recess between the recess and the entrance / exit of the bathroom. A base material layer, a cushion part laminated on the upper surface of the concave part and housed in the concave part, provided on the inner side of the bathroom and laminated on the upper surface of the edge part, and the amount of deformation in the vertical direction is larger than that of the cushion part. A cushion layer having a water resistance at least on the surface, a slope member provided on the surface of the cushion layer from the entrance / exit of a bathroom, the slope member and the cushion layer A bathroom washroom floor having a sealing portion that is watertightly sealed with a sealing material to prevent water from entering between the surface and the surface of the slope member, and is in contact with the surface of the cushion layer of the slope member An end of the bathroom is disposed at the peripheral edge layered on the upper surface of the edge, and the sealing part is disposed above the edge on the outer side of the recess. A floor is provided.

  According to the present invention, the sealing material for imparting softness to the washing floor and preventing water from entering between the slope member and the cushion layer may be cut or detached even when used for a long time. A washroom floor for the bathroom 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 cushion layer on the washing floor, it is necessary to impart characteristics satisfying the basic performance of the unit bath, such as water resistance, to the surface exposed to the inside of the bathroom.

  A cushion layer that satisfies the above-described characteristics is difficult to ensure sufficient strength to support a load, and a separate base material layer that supports the load more than the cushion layer is required. That is, in order to ensure the minimum basic performance required for a washing floor while giving softness to the washing floor, a combination of a cushion layer having water resistance at least on the surface and a base material layer having sufficient strength is combined. It is desirable to have a structure.

[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 has sufficient strength not to bend or break even when subjected to static loads such as wall panels, 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 thermoplastic resin such as polypropylene or polyethylene reinforced.

  The base material layer 1 is formed in a generally shallow bread shape, and the base material layer 1 is provided with a recess 2. The recess 2 occupies most of the area of the base material layer 1 as viewed from above, and an edge 1b that is one step higher than the top surface (bottom surface) of the recess 2 is provided between the recess 2 and the entrance / exit 40 of the bathroom. Is provided.

  FIG. 2 is a schematic perspective view of the base material layer 1, and a drain pit 15 is formed in an opening in a part of the base material layer 1. On the outermost edge portion of the base material layer 1, a side wall portion 1a that functions as a water return wall rising upward is provided. The edge part 1b is provided only in a part corresponding to the entrance / exit part of the bathroom.

  The base material layer 1 is integrally formed by hot-molding a hard material (for example, FRP), and thus the concave portion 2, the edge portion 1b, and the side wall portion 1a 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 so as to cover the upper surface of the cushion material 4 and the recess 2, and is bonded and fixed to the upper surface of the cushion material 4 with an adhesive material such as a double-sided tape. A part of the surface material 5 extends to the entrance / exit 40 side of the cushion material 4 and is bonded and fixed to the upper surface of the edge portion 1b of the base material layer 1 without using the cushion material 4 with an adhesive such as double-sided tape. The

  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.

  Further, as shown in FIG. 3, a groove 5a is formed on the surface of the surface material 5 so as to be continuous with the drain outlet or the drainage groove. The groove 5a 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 5a is a drainage channel that allows water to continuously exist without interruption to the drainage port or drainage channel. By this groove 5a, 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 5a on the surface of the surface material 5, irregularities are 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 by using an adhesive such as double-sided tape, and the surface of the cushion material 4 is further 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.

  A door DR is installed at the entrance 40 of the bathroom. The four sides around the door DR are surrounded by a door frame, and the door DR is attached and held to the door frame so as to be freely opened and closed. FIG. 1 shows only the door lower frame 30. The door lower frame 30 is provided on the outermost edge portion on the outer side (the entrance / exit portion 40 side) than the concave portion 2 and the edge portion 1 b in the base material layer 1.

  A slope member 31 extends from the door lower frame 30 toward the surface material 5 in the bathroom. The slope member 31 and the door lower frame 30 may be integrated or separate. The slope member 31 is gently inclined downward in the direction from the entrance / exit part 40 toward the surface material 5, and thus there is no step between the entrance / exit part 40 and the surface material 5 in the bathroom, and it is barrier-free. It has become.

  The end of the slope member 31 on the side in contact with the surface of the surface material 5 is disposed on the portion 5b laminated on the base material layer edge 1b of the surface material 5, and the slope member 31 and the surface material are disposed on the portion. A seal portion 10 is provided for preventing water from entering between 5 and 5 and entering the back side of the cushion layer 3. Specifically, for example, the gap between the slope member 31 and the surface of the surface material 5 is sealed (sealed) with a sealing material 11 such as silicon or a joint member.

  The portion 5b of the surface material 5 provided with the sealing material 11 and the end portion of the slope member 31 are supported on the edge 1b of the hard base material layer 1 without the cushion material 4 interposed therebetween. Even if a load is applied from above when a person enters or exits, it will not bend greatly in the thickness direction (vertical direction), and it will not bend, so it will recover greatly from the bent (sinked) state. Nor. That is, the portion where the sealing material 11 is provided does not vary greatly in the vertical direction. Therefore, a large stress that pulls or lifts the sealing material 11 does not act, and the sealing material 11 does not break or come off. As a result, sealing performance and appearance are not impaired.

  That is, according to the present embodiment, the sealing material 11 for imparting softness to the washroom floor and preventing water from entering between the slope member 31 and the cushion layer 3 is used for a long time. It is possible to provide a washing floor that does not break or come off.

[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 a hard base layer 21 and a cushion layer 23 having cushioning properties laminated on the base layer 21.

  The base material layer 21 is waterproof so that hot water does not leak out of the bathroom, and has sufficient strength not to bend or break even when subjected to static loads such as wall panels, 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 thermoplastic resin such as polypropylene or polyethylene reinforced.

  The base material layer 21 includes a shallow bread-shaped base material portion 22 and an edge member 6 provided separately from the base material portion 22 on the upper surface portion (bottom surface portion) 22 b of the base material portion 22. Have. The edge member 6 is a component corresponding to the edge portion 1 b in the first embodiment, and the edge member 6 is made of a material harder than the cushion layer 23. In addition, a side wall portion 22 a that functions as a water return wall that rises 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 6 is fixedly bonded or welded to the vicinity of the entrance / exit portion 40 on the upper surface. The edge member 6 is provided between the concave portion 2 and the entrance / exit portion 40 so as to be one step higher than the upper surface (bottom surface) of the concave portion 2, similarly to the edge portion 1 b of the first embodiment described above. The edge member 6 is provided only in a part corresponding to the entrance / exit part 40 of the bathroom.

  The cushion layer 23 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.

  The cushion portion 23b occupying most of the cushion layer 23 is accommodated in the recess 2 of the base material layer 21, and is bonded and fixed to the upper surface (bottom surface) of the recess 2 with an adhesive such as double-sided tape. The cushion part 23b is elastically deformable, and is made of a foamed material such as urethane.

  Since the surface of the cushion layer 23 is exposed in the bathroom and becomes a surface that is touched by the user or exposed to hot water, it has water resistance, chemical resistance, and impact resistance, and also elastically deforms the cushion portion 23b. Flexible to follow.

  In the surface layer portion located inside the bathroom of the cushion layer 23, the peripheral edge portion 23a on the entrance / exit portion 40 side of the bathroom extends to the entrance / exit portion 40 side with respect to the recessed portion 2 and the edge member 6, and the peripheral edge portion 23a is the cushion portion 23b. It is laminated | stacked on the upper surface of the edge member 6 of the base material layer 21 without going through. The peripheral edge 23a is bonded and fixed to the upper surface of the edge member 6 with an adhesive such as a double-sided tape.

Since the peripheral portion 23a is thinner than the cushion portion 23b, the amount of deformation in the vertical direction is extremely small. Specifically, the peripheral portion 23a has a thickness (8 cm or less, preferably not much elastically deformed in the vertical direction). 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 23 a is suppressed to 0.5 mm to 2.0 mm. Thus, the cushion layer 23 having the cushion portion 23b and the peripheral edge portion 23a 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 23b is formed thicker on the back surface than the peripheral part 23a.

  Also in FIG. 4, only the door lower frame 30 is shown among the door frames surrounding the bathroom door DR as in FIG. The door lower frame 30 is provided on the outermost edge part on the outer side (the entrance / exit part 40 side) of the base material layer 21 with respect to the recess 2 and the edge member 6.

  A slope member 31 extends from the door lower frame 30 toward the surface of the cushion layer 23 in the bathroom. The slope member 31 is gently inclined downward in the direction from the entrance / exit part 40 toward the surface of the cushion layer 23, so that there is no step between the entrance / exit part 40 and the surface of the cushion layer 23 in the bathroom. It is free.

  The end of the slope member 31 on the side in contact with the surface of the cushion layer 23 is disposed on the peripheral edge portion 23 a laminated on the base material layer edge member 6 in the cushion layer 23, and the slope member 31 and the cushion are disposed in that portion. A seal portion 10 is provided for preventing water from entering between the layers 23 and entering the back side of the cushion layer 23. Specifically, for example, the gap between the slope member 31 and the cushion layer 23 surface is sealed (sealed) with a sealing material 11 such as silicon or a joint member.

  The peripheral edge portion 23a of the cushion layer 23 provided with the sealing material 11 and the end portion of the slope member 31 are supported on the hard edge member 6 without the cushion 23b. Therefore, even if a load is applied, it will not bend greatly in the thickness direction (vertical direction), and will not be bent, so it will not be greatly restored upward from the bent (sunk) state. That is, the portion where the sealing material 11 is provided does not vary greatly in the vertical direction. Therefore, a large stress that pulls or lifts the sealing material 11 does not act, and the sealing material 11 does not break or come off. As a result, sealing performance and appearance are not impaired.

  That is, also in the present embodiment, the sealing material 11 for providing softness to the washing floor and preventing water from entering between the slope member 31 and the cushion layer 23 is used over a long period of time. It is possible to provide a washing floor that does not break or come off.

  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.

  The single-layer structure cushion layer 23 shown in the second embodiment may be combined with the monolithic base material layer 1 in the first embodiment, or a separate structure shown in the second embodiment. The cushion layer 3 having the two-layer structure of the first embodiment may be combined with the base material layer 21.
