  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.

  The cushion layer expands and contracts in the vertical direction when a load is applied from the floor surface of the washing place, but when the peripheral edge of the cushion layer also expands and contracts in the vertical direction, the silicon provided in that portion There are concerns about problems such as cutting, disconnecting joints, impairing watertightness, and poor appearance.

  In addition, as a measure to prevent the sealing material from being cut or detached, it is preferable that the base material layer can be applied to a washing floor that does not provide cushioning properties, so the shape of the base material layer itself is not a special shape. It is preferable. In that case, a member separate from the base material layer is required, but it is preferable that this member can be used for various sizes of washroom floors.

  The present invention was made in view of the above-mentioned problems, and the sealing material for preventing water from entering between the base material layer and the cushion layer does not break or come off even when used for a long period of time, and As a countermeasure, a bathroom washroom floor that can accommodate various sizes of washroom floors without providing a special shape for the base material layer itself is provided.

According to one aspect of the invention,
A hard base material layer in which a concave portion is formed on the inner side of the edge portion by attaching and fixing the edge member formed separately on the upper surface portion in a frame shape, and
A cushion layer that is laminated on the base material so as to cover the concave portion and whose end portion is located on the edge member, and capable of extending and contracting in the vertical direction;
In order to prevent water from entering between the base material layer and the cushion layer, a seal portion is provided that seals a peripheral edge portion of the cushion layer located on the edge portion with a sealing material in a watertight manner. A bathroom floor,
The portion of the cushion layer located on the edge member is configured such that the vertical expansion and contraction is smaller than the portion located on the recess,
The said edge member is formed in frame shape from the several member formed by division, The washroom floor for bathrooms characterized by the above-mentioned is provided.

  According to the present invention, the sealing material for preventing water from entering between the base material layer and the cushion layer does not break or come off even when used for a long time. There is provided a bathroom washroom floor that can accommodate various sizes of washroom floors without the material layer itself having a special shape.

  In order to impart softness to the washroom floor of the bathroom, it is conceivable to construct the washroom floor with a material having a cushioning property that can be elastically deformed. However, when the washing floor is made of a cushioning material, it is difficult to ensure sufficient strength to support the load, and a base material layer that is stronger than the cushion layer to support the load is required. It becomes. That is, it is desirable to have a structure in which at least a base material layer and a cushion layer are combined in order to ensure the minimum basic performance required for the washing floor while giving softness to the washing floor.

  In addition, the surface of the washroom floor needs to satisfy basic performances required for the washroom floor, such as water resistance, chemical resistance, and impact resistance. In order to satisfy these requirements, the cushion layer is formed of a material different from the cushion material that can be expanded and contracted in the vertical direction and the flexible cushion material on the surface side of the cushion material. It is necessary to form a cushion layer having a two-layer structure in which surface materials satisfying basic performance are laminated. In this case, the surface material is preferably a thin sheet that does not deteriorate the cushioning property of the cushion material in the lower layer.

  Furthermore, if water permeates between the base material layer and the cushion layer, the cushion layer may get wet and the cushioning properties may deteriorate or mold may form. It is necessary to seal the water tight with a sealing material.

  However, the cushion layer expands and contracts (moves) in the vertical direction when a load is applied from the washing floor, but if the peripheral edge of the cushion layer expands and contracts in the vertical direction as well, that portion There is a concern that the silicon provided on the metal may break, the joints may be removed, the water tightness may be impaired, and the appearance may deteriorate. Therefore, in the embodiment of the present invention described below, a sealing material for providing softness to the washing floor and preventing water from entering between the base material layer and the cushion layer is used for a long time. Provide bathroom washroom floors that never break or come off.

[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 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 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 in a flat shape, and the edge member 23 is fixedly bonded or welded to the edge portion in the vicinity of the inner side of the side wall portion 24 on the upper surface. The edge member 23 may be provided over the entire periphery of the edge of the washroom floor, or may be provided only in a portion that is particularly required for measures against seal breakage (such as around the entrance / exit portion and the drain port).

  The edge member 23 forms a recess 25 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 so as to cover the upper surface of the cushion material 4 and the recess 25. The planar size of the surface material 5 is larger than the planar size of the cushion material 4 (it is formed longer in both length and width), and the peripheral edge portion 5 a that protrudes from the cushion material 4 in the surface material 5 does not go through the cushion material 4 but the edge member 23. Is laminated and fixed on the upper surface of the substrate.

  In order to prevent water from entering between the cushion layer 3 and the edge member 23 of the base material layer 21 at the peripheral edge of the surface material 5 disposed on the outer side from the recess 25, the surface material 5 A sealing portion 30 is provided that seals the peripheral edge of each of the peripheral portions with a sealing material 31 such as silicon or a joint member.

  Since the peripheral portion 5a of the surface material 5 provided with the sealing material 31 is bonded and fixed to the hard edge member 23 without the cushion material 4 interposed therebetween, even if a load is applied to the peripheral portion 5a, the thickness direction ( Since it does not bend greatly in the vertical direction) and does not bend, it will not be greatly restored upward from the bent (sunk) state. That is, the peripheral edge portion 5a does not vary greatly in the vertical direction. Therefore, a large stress that pulls or lifts the sealing material 31 provided on the peripheral edge 5a does not act, and the sealing material 31 does not break or come off. As a result, sealing performance and appearance are not impaired.

  Therefore, also in this embodiment, the sealing material 31 for imparting softness to the washing floor and preventing water from entering between the base material layer 21 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.

  Moreover, in this embodiment, since it is the structure which provided the edge member 23 separately with respect to the base part 22 of a simple shallow bread shape, the existing washroom floor bread can be diverted as it is, and this embodiment is easy. The structure of can be applied.

  In addition, a wall panel mounting portion 22 b for mounting the wall panel 50 is provided on the outer side of the seal portion 30. On the upper surface of the upper surface portion 22 a of the base material portion 22, a portion between the portion where the edge member 23 is provided and the side wall portion 24 functions as the wall panel placement portion 22 b.

  The sealing material 31 performs watertight sealing between the peripheral edge portion 5 a of the surface material 5 and the base material layer edge member 23 and between the wall panel 50 and the edge member 23. The sealing material 31 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 31 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 seal between the peripheral edge portion 5a of the surface material 5 and the edge member 23 and the seal between the wall panel 50 and the edge member 23 are performed by the same one seal portion 30. One sealing material 31 can also be used, and only one sealing material 31 is required, and the above problem can be suppressed.

  Since the wall panel 50 is placed on the wall panel placement portion 22b which is a part of the hard base material portion 22 and is not placed on the cushion layer 3, maintenance (replacement) of the cushion layer 3 is performed. There is no need to dismantle the bathroom unit. Further, the wall panel 50 is not inclined due to the elastic deformation of the cushion layer 3 and the support of the wall panel 50 and the ceiling panel thereon is not unstable.

[Second Embodiment]
FIG. 2 is a schematic cross-sectional view of a bathroom wash floor according to the second embodiment of the present invention. The first embodiment is different from the first embodiment only in that the cushion layer is formed as a single layer, and the rest has the same configuration, operation, and effect, and thus the description thereof is omitted.

  The cushion layer 3 in this embodiment 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.

  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.

  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 order to prevent water from entering between the cushion layer 3 and the base material layer 1 in the peripheral edge portion 4b of the cushion layer 3 disposed on the outer side from the concave portion of the base material layer 1, the peripheral edge portion 4b. For example, a sealing portion 30 is provided for watertightly sealing with a sealing material 31 such as silicon or a joint member.

  Since the peripheral edge 4b of the cushion layer 3 provided with the sealing material 31 is bonded and fixed to the edge member 23 of the hard base material layer 1 without the cushion 4a interposed, a load is applied to the peripheral edge 4b. Also, there is no significant bending in the thickness direction (vertical direction), and there is no bending, so there is no significant upward recovery from the bent (sunk) state. That is, the peripheral edge 4b does not vary greatly in the vertical direction. Therefore, a large stress that pulls or lifts the sealing material 31 provided on the peripheral edge 4b does not act, and the sealing material 31 does not break or come off. As a result, sealing performance and appearance are not impaired.

  The portion where the peripheral edge portion 4b is bonded to the hard edge member 23 without the cushion portion 4a interposed may be provided over the entire periphery of the edge of the washing floor, or is particularly required for measures against seal breakage. You may provide only in a part. Here, the “parts that are particularly required” are edges that are frequently stepped on by the user on the washing floor, for example, the edges such as the entrance / exit part and the periphery of the drainage port. In other words, the cushion portion 4a may be provided in the vicinity of the sealing material 31 without adopting the above-described structure, for example, at the edge under the counter, which is less likely to be stepped on by the user and less likely to be loaded. .

  According to this embodiment, the sealing material 31 for preventing soft water from entering between the base material layer 1 and the cushion layer 3 while providing softness to the washing floor is used for a long time. It is possible to provide a washing floor that does not break or come off.

  Below, the edge member 23 demonstrated in 1st Embodiment and 2nd Embodiment is demonstrated in detail. As shown in FIG. 3, the edge member 23 attached to the flat upper surface portion 22a of the base material portion 22 is formed in a frame shape by dividing a plurality of members and integrally abutting the plurality of members. Has been.

  The edge member 23 is disposed in a substantially mouth shape with respect to the base material portion 22 formed in a rectangular shape in plan view. Specifically, the bathtub-side long side edge 44 disposed on the long side adjacent to the bathtub and the long side opposite to the bathtub at a position away from the bathtub are substantially the same as the bathtub side long side edge 44. The bathtub-side long side edge 43, the left-side short side edge 41 that connects one end of the bathtub-side long side edge 44 and the one end of the bathtub-side long-side edge 43, and the bathtub side A right-side short side edge part 42 that connects the other end part side of the long side edge part 44 and the other end part side of the bathtub separating side long side edge part 43 is provided.

  These edge portions 41, 42, 43, and 44 are formed separately. Furthermore, a wash basin drain port portion is formed in the center of the long side portion adjacent to the bathtub, and the bathtub side long side edge portion 44 includes a drain port edge portion 45 formed so as to follow the shape of the drain port portion. The bathtub-side left edge 46 that connects one end side of the drain port edge 45 to the end side of the left short edge 41 and the end of the right short edge 42 from the other end of the drain port 45 The bathtub side right edge part 47 which connects the side is comprised, and the edge parts 45, 46, and 47 are each dividedly formed.

  Moreover, as shown to Fig.4 (a), the drain port edge 45 is formed in the concave shape opened to the bathtub side by planar view. Moreover, as shown to Fig.5 (a), between the one end part of the bathtub side long side edge part 44, and the left side short side edge part 41, the L-shaped corner piece 49 by the planar view dividedly formed is formed. It is attached. This corner piece 49 is between one end of the bathtub separating side long side edge 43 and the left short side edge 41, between the other end of the bathtub separating side long side edge 43 and the right short side edge 42, and It is similarly disposed between the other end of the bathtub-side long side edge 44 and the right short side edge 42.

  As described above, the edge member 23 is configured to be divided from a plurality of edge portions, thereby providing the following effects. Usually, the washroom floor is available in various sizes. That is, there are a plurality of planar sizes of the base material portion 22. It is not preferable from the viewpoint of cost to manufacture the edge member 23 formed into a frame shape for each of the base material portions 22 of various sizes. On the other hand, since the edge member 23 is divided and formed as in the present invention, at least the edge portions 41, 42, 43, 46, 47 can be obtained simply by cutting the edge member 23 formed in a straight line according to the size. It is possible to cover with a single molded product. At this time, the cross-sectional shapes of the edges 41, 42, 43, 46, 47 are preferably the same. In addition, since the size of the washing ground drainage port is often the same size even when the size of the washing ground floor changes, if one drainage edge 45 is prepared, various sizes of the washing floor Is possible. In addition, since the corner pieces 49 arranged at the four corners of the washroom floor are formed in an L shape, it is possible to cover the corner pieces at the four corners with a single molded product.

  As described above, by configuring the edge member 23 from a plurality of divided edges, it is possible to deal with various sizes of washroom floors, and thus manufacturing costs can be greatly reduced.

  Furthermore, on the upper surface and the lower surface of the edge member 23 in the present invention, a caulking groove 71 filled with a caulking agent (e.g., silicon) is formed, respectively. Each is attached in communication. Tape grooves 72 to which an adhesive tape is attached are respectively formed on the upper surface and the lower surface of the edge member 23, and these tape grooves 72 are also attached in a state where they are communicated with each other.

  The caulking agent with which the upper surface of the edge member 23 is filled is intended for adhesion and water stop between the edge portion 5a of the surface material 5 or the back surface of the edge portion 4b of the cushion layer and the upper surface of the edge member 23. The caulking agent filled in the lower surface of the edge member 23 is intended for adhesion and water stop between the upper surface of the base member 22 and the lower surface of the edge member 23. By providing the groove, the caulking agent can be fixed and fixed at an arbitrary position. In addition, there is also an effect that the surface of the washing floor where the caulking agent is applied or where the tape portion is adhered is not raised.

  The caulking groove 71 and the tape groove 72 formed on the upper surface and the lower surface of each edge 23 are installed in a state of communicating in a frame shape. The purpose of this is to make the water stop line continuous without gaps.

  Therefore, using a corner piece 49 having a caulking groove (communication groove) 71 and a tape groove 72 formed in an L shape, a water stop line is secured even in a portion where two edges intersect at a right angle. Like to do.

  In the case where the corner piece 49 is not provided, the end portions of the two edge portions installed in a state of intersecting at a right angle are formed in an inclined shape of approximately 45 degrees in plan view. By doing in this way, it becomes possible to form the continuous frame-shaped water stop line, without providing a corner piece.

  As shown in FIG. 6, the side surface of the edge member 23 on the concave side is formed in an inclined shape such that the lower part has an acute angle and the upper part has an obtuse angle than the lower part. As described above, the wash floor surface on the recess has cushioning properties, but the wash floor surface on the edge has low cushion properties. For this reason, when the side surface on the concave portion side of the edge member 23 is formed at a right angle to the base material portion, when the wheelchair user enters the washing floor, there is a possibility that a step is felt. According to the present invention, the side surface on the concave portion side of the edge member 23 is gently inclined with respect to the base material portion (an inclination angle of 20 to 70 degrees with respect to the base material portion). This is preferable because there is no difference in level when moving between the two.
