  The wall surface connecting member 50 has a hollow structure formed by bending a thin plate. The left and right folded portions 501 of the wall surface connecting member 50 have elasticity.

  In FIG. 2A, the mounting state of the two wall panels 31-1 and 31-2 that form the wall panel 31 is shown. The left and right side surfaces of the steel plate 311 of the two wall panels 31-1 and 31-2 are provided with elastically folded back portions 502-1 and 502-2, respectively.

  To attach the two wall panels 31-1 and 31-2 to the wall surface connecting member 50A, the folded portions 502-1 and 502-2 are fitted between the left and right folded portions 501 of the wall surface connecting member 50A. The folded-back portions 502-1 and 502-2 are urged toward each other by being fitted in such a manner that the space between the folded-back portions 501 on the left and right is widened. When the folded-back portions 502-1 and 502-2 are fitted, the two wall panels 31-1 and 31-2 are fixed in the same plane with the wall surface connecting member 50A in between.

  FIG. 2B shows a mounting state of the wall panel 31-2 and the wall panel 32, which form the wall panel 31. The steel plate 311-2 of the wall panel 31-2 is provided with the folded back portion 502-1, and the steel plate 321 of the wall panel 32 is provided with the folded back portion 502-1. The folded-back portions 502-1 and 502-2 each have elasticity.

  The folded-back portions 502-1 and 502-2 are fitted so as to widen the space between the folded-back portions 501 on the left and right. When the folded-back portions 502-1 and 502-2 are fitted, the two wall panels 31-2 and 32 are fixed in a state of being orthogonal to each other with the wall surface connecting member 50A therebetween.

  As described above, since the folded-back portion 501 of the wall surface connecting member 50 and the folded-back portion 502 of each wall panel have elasticity along the plane orthogonal to the wall 3, their installation positions are fixed. On the other hand, in the direction along the surface of the wall 3, the wall surface connecting member 50 does not regulate the position. Therefore, when the respective wall panels are fitted into the wall surface connecting member 50, they drop downward due to their own weight, and their lower ends (tip portions 311a described later) come into contact with the floor surface member 21.

FIG. 3 is a perspective view showing a wall mounting structure in the present embodiment.
As shown in FIG. 3, a plurality of wall surface connecting members 50 extending in a direction orthogonal to the upper surface of the wash floor 2 are attached to the outer peripheral portion 2 a of the wash floor 2. The wall surface connecting member 50 is fixed to the wall surface fixing member 51 that has been attached in advance by fastening means such as bolts and screws. At this time, the wall surface connecting member 50 may be fixed such that the lower end of the wall surface connecting member 50 presses the outer peripheral portion 2a of the floor surface member 21 downward. The wall panels 31 to 35 are fixed by fitting the wall panels to the respective wall connection members 50. The wall panel 37 is fixed between the bathtub 1 and the wall surface connecting member 50. The wall panel 36 is fixed between one end of the wall panel 34 and one end of the wall panel 35.

FIG. 4 is an exploded perspective view illustrating the configuration of the washing floor according to the present embodiment.
As shown in FIG. 4, the wash floor 2 has a floor base material 20 and a skin material 23 arranged on the floor base material 20. The floor base material 20 has a support material 22, a floor surface material 21, and a cushion material 201 in order from the bottom.

  The support member 22 has four support legs 231 provided at four corners. The support leg 231 is configured such that the height can be adjusted by rotating the bolt portion. As the support member 22, a flat plate-shaped material having relatively high strength and rigidity is used. An example of such a material is a sandwich panel. The sandwich panel has, for example, a structure in which a plastic plate material is sandwiched between two steel plates, is lightweight and has high rigidity, and a fastening member such as a screw can also be used. The support member 22 is provided with a work opening so that an operator can go under the floor. After the construction, the work port is covered with the lid 221.

  As will be described later, the floor surface member 21 is provided with a concave portion serving as a drainage port and an inclined surface for forming a slope of the upper surface of the wash floor 2. The floor material 21 is made of, for example, a thermoplastic resin. Floor material 21 may be formed of fiber reinforced plastic (FRP). As the thermoplastic resin, for example, expanded polypropylene, expanded polystyrene, expanded polyethylene, expanded polyurethane or the like is used.

  A cushion member 201 is provided on the floor surface member 21. For the cushion material 201, a soft material such as foamed polyurethane is used. By changing the hardness (softness) of the cushion material 201, the hardness (softness) of the floor surface felt when the skin material 23 is stepped on can be changed.

  The skin material 23 is arranged on the outermost surface of the wash floor 2, and a soft sheet material having waterproofness and flexibility is used. The skin material 202 may be subjected to uneven processing or a patterned pattern in order to improve the design and drainage of the surface of the wash floor 2.

A recess is formed on the outer periphery of the floor material 21, and the wall 3 is installed on this recess. This point will be described more specifically with reference to FIGS.
FIG. 5 is an enlarged perspective sectional view of a part of the wash floor and a part of the wall according to the present embodiment.
FIG. 6 is an enlarged perspective sectional view of a portion B of FIG.
FIG. 7 is an enlarged cross-sectional view of a part of the wash floor and a part of the wall according to the present embodiment.
Note that the support member 22 is omitted in FIGS. 5 to 7.

  As shown in FIG. 6, the steel plate 311 extends toward the floor surface member 21, and the tip 311 a is bent toward the outside of the wash floor 2. A recess 21R is formed on the outer periphery of the floor material 21, and a guide piece 27 is attached to the inside of this recess. A tip portion 311a is placed on the guide piece 27 via a packing PK1. The floor material 21 is pressed downward by the weight of the wall 3. The tip of the tip 311 a is fixed by the guide piece 27. By doing so, the displacement of the relative positional relationship between the wash floor 2 and the wall 3 is suppressed.

  As shown in FIG. 7, among the side walls of the recess 21R, the dry joint 25 is provided in the gap between the side wall S1 located inside the washing floor 2 and the steel plate 311. The dry joint 25 covers the gap between the side wall S1 of the recess 21R and the steel plate 311.

The dry joint 25 has a first end 251 on one end side and a second end 252 on the other end side. The first end portion 251 is fixed to the lower surface of the skin material 23 or the upper surface of the floor material 21, and is located between the skin material 23 and the floor material 21. At this time, it is desirable that the first end portion 251 of the dry joint 25 is not located between the cushion material 201 and the skin material 23. The second end 252 of the dry joint 25 is in contact with the steel plate 311. Part of the dry joint 25 is bent along the side surface 23S of the skin material 23, and the second end 252 of the dry joint 25 is located above the first end 251. The upper surface of the other end of the dry joint 25 is located above the upper surface of the skin material 23.

  The dry joint 25 has elasticity. Further, the dry joint 25 may be soft enough to be easily deformed. Further, the dry joint 25 may be formed in a thin shape. Since the dry joint 25 is at least one of soft and thin, the second end portion 252 of the dry joint 25 can be easily deformed when it is deformed upward.

  The dry joints 25 include polyolefin resins such as polypropylene and polyethylene, styrene resins such as polystyrene and ABS (acrylonitrile butadiene styrene copolymer), polyester resins such as vinyl chloride and polyethylene terephthalate, polyamide resins such as nylon, and fluorine. Resin or the like can be used. By using these materials, elasticity and softness can be imparted to the dry joint 25.

FIG. 8 is an enlarged plan view of the vicinity of the recess on the floor of the washroom before the wall panel is installed.
FIG. 9 is a sectional view taken along the line AA ′ of FIG.
In addition, in FIG. 8 and FIG. 9, the wall panel 31 placed after that is shown with the broken line.

  As shown in FIGS. 8 and 9, when the wall panel 31 is not installed, the dry joint 25 extends in the horizontal direction and projects toward the outside of the wash floor 2. At this time, the length L1 of the portion protruding above the recess 21R is longer than the distance D1 between the side wall S1 and the steel plate 311 in the state where the wall panel is installed. Therefore, when the wall panel 31 is installed, the second end 252 of the dry joint 25 abuts against the steel plate 311 and bends, so that the upper surface of the dry joint 25 moves downward from the steel plate 311 toward the skin material 23. Tilt to.

Here, the procedure for attaching the dry joint and the wall panel will be described with reference to FIGS. 10 to 13.
10 to 13 are cross-sectional views showing a method for constructing a dry joint of a bathroom according to this embodiment.
First, as shown in FIG. 10A, the first end 251 of the dry joint 25 is fixed to the end of the lower surface of the skin material 23. The dry joint 25 is fixed to the lower surface of the skin material 23 with a double-sided tape T, for example. Alternatively, they may be fixed with an adhesive, heat welding, staples, or the like.

  Next, as illustrated in FIG. 10B, the skin material 23 is attached to the surface of the floor surface material 21 in which the guide piece 27 is provided in the recess 21R. At this time, the skin material 23 is attached to the floor surface material 21 so that the portion of the dry joint 25 fixed to the skin material 23 is sandwiched between the skin material 23 and the floor material 21.

  FIG. 11A shows a state in which the skin material 23 is arranged on the floor material 21. As shown in FIG. 11A, the dry joint 25 extends toward the outside of the skin material 23 so as to cover a part of the recess 21R.

  Next, as shown in FIGS. 11B and 12A, the second end 252 of the dry joint 25 is displaced toward the inside of the skin material 23. Specifically, the second end 252 of the dry joint 25 is deformed upward and temporarily fixed to the skin material 23. For fixing to the skin material 23, for example, a masking tape M is used.

  Next, as shown in FIGS. 12B and 13A, the wall panel 31 is moved downward from above the floor surface material 21 and the skin material 23 to the recess 21R, and Place on. At this time, since the second end 252 of the dry joint 25 is fixed to the skin material 23, it is possible to avoid contact between the wall panel 31 and the dry joint 25.

  Finally, as shown in FIG. 13B, the state in which the second end 252 of the dry joint 25 is displaced is released. Specifically, the masking tape M attached to the second end 252 of the dry joint 25 is removed. At this time, since the dry joint 25 has elasticity, releasing the displacement of the second end 252 of the dry joint 25 causes a force to return to the original shape shown in FIG. 11A. As a result, the gap between the side wall S1 and the steel plate 311 is covered with the dry joint 25, and the tip of the dry joint 25 contacts the steel plate 311. As described above, since the length L1 of the protruding portion of the dry joint 25 is longer than the distance D1, the dry joint 25 contacts the steel plate 311 in a bent state, and the upper surface of the dry joint 25 covers the steel plate 311 to the skin. Incline downward toward the material 23.

  In the above description, the wall panel 31 is described as an example, but the other wall panels 32, 33, and 37 are similarly installed on the wash floor 2.

In the attachment procedure shown in FIG. 11, the second end 252 of the dry joint 25 is deformed to displace the second end 252. However, the present embodiment is not limited to this, and for example, the dry joint 25 is provided slidably with respect to the skin material 23 and the floor material 21, and the dry joint 25 is moved toward the inside of the skin material 23. By doing so, the second end portion 252 of the dry joint 25 may be displaced. In this case, by moving the dry joint 25 toward the outside of the skin material 23, the state in which the second end 252 of the dry joint 25 is displaced is released.
Alternatively, the skin material 23 is provided so as to be slidable with respect to the floor surface material 21, and by moving the skin material 23 toward the inside of the floor surface material 21, the second end 252 of the dry joint 25 is formed. May be displaced. In this case, by moving the skin material 23 toward the outside of the floor material 21, the state in which the second end portion 252 of the dry joint 25 is displaced is released.

Next, the structure of the outer circumference of the bathtub 1 will be specifically described with reference to FIG.
FIG. 14 is an enlarged sectional view of a part of the bathtub and a part of the wall according to the present embodiment.
As shown in FIG. 14, the wall panel 36 has a base material 360 and a back plate 361. A concave portion 1R is formed on the outer periphery of the bathtub 1, and the lower end of the base material 360 is placed on the bottom surface of the concave portion 1R via a packing PK2.

  The base material 360 faces the side wall S2 located inward of the bathtub 1 among the side walls of the recess 1R. A dry joint 26 is provided in the gap with the side wall S2 steel plate 311. The dry joint 26 has a first end 261 on one end side and a second end 262 on the other end side. The first end 261 is fixed to the side wall S2, and the second end 262 abuts the base material 360 to cover the gap between the side wall S2 and the base material 360.

  The dry joint 26 has elasticity. Further, like the dry joint 25, it may be at least one of soft and thin. The same material as the dry joint 25 can be used for the dry joint 26.

FIG. 15 is an enlarged plan view of the vicinity of the recess before the wall panel is installed.
16 is a cross-sectional view taken along the line CC ′ of FIG.
In addition, in FIG. 15 and FIG. 16, the wall panel 36 placed after that is shown with the broken line.

  As shown in FIGS. 15 and 16, when the wall panel 36 is not installed, the dry joint 26 extends horizontally and projects toward the outside of the bathroom. At this time, the length L2 of the portion protruding above the recess 1R is longer than the distance D2 between the side wall S2 and the wall panel 36 in the state where the wall panel is installed. Therefore, in the state where the wall panel is installed, the second end 262 of the dry joint 26 abuts against the base material 360 and bends, so that the upper surface of the dry joint 26 moves downward from the base material 360 toward the bathtub 1. Tilt to.

  The attachment of the dry joint 26 to the bathtub 1 and the installation of the wall panel 36 are performed in the same manner as the attachment of the dry joint 25 to the wash floor 2 and the installation of the wall panel 31.

  That is, first, the first end 261 of the dry joint 26 is fixed to the side wall S1 of the recess 1R. The dry joint 26 is fixed by, for example, a double-sided tape or an adhesive. Alternatively, they may be fixed by welding by heat, staples, or the like.

  Next, the second end 262 of the dry joint 26 is displaced toward the inside of the bathtub 1. Specifically, the second end 262 of the dry joint 26 is deformed upward and is temporarily fixed to the bathtub 1 with, for example, tape. Subsequently, the wall panel 36 is moved from above the bathtub 1 toward the recess 1R and placed. At this time, since the second end portion 262 of the dry joint 26 is deformed and fixed toward the inside of the bathtub 1, it is possible to avoid contact between the wall panel 36 and the dry joint 26.

  Then, when the state in which the second end 252 of the dry joint 25 is displaced is released, the gap between the side wall S2 and the base material 360 is covered with the dry joint 26, and the tip of the dry joint 26 contacts the wall panel 36. .. As described above, since the length L2 of the dry joint 26 is longer than the distance D2, the dry joint 26 abuts the wall panel 36 in a bent state, so that the upper surface of the dry joint 26 is inclined.

  In addition, in the attachment procedure of the wall panel 36 described above, the second end 262 is displaced by deforming the second end 262 of the dry joint 26. However, the present embodiment is not limited to this, and for example, the dry joint 26 is configured to be movable toward the inside of the bathtub 1, and the dry joint 26 is moved toward the inside of the bathtub 1 so that the dry joint is moved. The second end 262 of 26 may be displaced. In this case, by moving the dry joint 26 toward the outside of the bathtub 1, the state in which the second end 262 is displaced is released.

  In the above description, the wall panel 36 is described as an example, but the other wall panels 34 and 35 are similarly installed on the wash floor 2.

Next, the structure of the bathroom according to the modification of the present embodiment will be described with reference to FIGS. 17 and 18.
FIG. 17 is an enlarged cross-sectional view of a part of the wash floor and a part of the wall according to the modification of the present embodiment.
FIG. 18 is an enlarged cross-sectional view of a part of the bathtub and a part of the wall according to the modified example of the present embodiment.

  As shown in FIG. 17, a caulking material CK1 may be provided between the side wall S1 of the recess 21R and the wall panel 31 (steel plate 311). The first end 251 of the dry joint 25 is fixed to the wash floor 2, and the caulking material CK1 is covered by the second end 252 of the dry joint 25. By providing the caulking material CK1 in addition to the dry joint 25, it becomes possible to further improve the water blocking property between the wash floor 2 and the wall 3.

As shown in FIG. 18, a caulking material CK2 may be provided between the side wall S2 of the recess 1R and the wall panel 36 (base material 360). The first end 261 of the dry joint 26 is fixed to the bathtub 1, and the caulking material CK2 is covered by the second end 262 of the dry joint 26. By providing the caulking material CK2 in addition to the dry joint 26, it becomes possible to further improve the water blocking performance between the bathtub 1 and the wall 3.
Silicon is used for the caulking materials CK1 and CK2, for example.

  In the description of the above-described embodiment and its modified example, the case where the dry joint 25 covers the entire gap between the side wall S1 and the steel plate 311, and the dry joint 26 covers the entire gap between the side wall S2 and the base metal 360. explained. However, the present embodiment is not limited to this, and the dry joint 25 covers at least a part of the gap between the side wall S1 and the steel plate 311, and the dry joint 26 covers at least a part of the gap between the side wall S2 and the base material 360. All you have to do is cover it.

  In this embodiment, a dry joint 25 is provided between the wash floor 2 and the wall 3, and a dry joint 26 is provided between the bathtub 1 and the wall 3. These dry joints can be attached to the bathtub 1 and the wash floor 2 in advance before construction. By attaching dry joints 25 to the washing floor 2 and the bathtub 1 at the manufacturing site, for example, it is not necessary for the installer to attach the dry joints 25 at the construction site, and the dry joints 25 are easily removed. It is possible to suppress construction errors such as construction being performed or water leakage occurring due to displacement of the mounting position of the dry joint 25.

  Further, in the construction of the dry joint 25, the first end 251 of the dry joint 25 is fixed to the washing floor 2, and the wall 3 is moved in a state where the second end 252 is displaced toward the inside of the washing floor 2. It is placed in the recess 21R. According to such a method, when the wall 3 is placed, the possibility of damaging the dry joint 25 due to the contact between the wall 3 and the dry joint 25 is reduced, and the wall 3 is easily placed. it can.

  Similarly, in the construction of the dry joint 26, the first end 261 of the dry joint 26 is fixed to the bathtub 1, and the wall 3 is recessed in the recess 1R in a state where the second end 262 is displaced toward the inside of the bathtub 1. To place. According to such a method, when the wall 3 is placed, the possibility of damaging the dry joint 26 due to the contact between the wall 3 and the dry joint 26 is reduced, and the wall 3 is easily placed. it can.

Moreover, like the wall panel 31 shown in FIG. 2 and FIG. 3, one wall surface of the bathroom is composed of a plurality of wall panels, so that the size of each wall can be reduced. As a result, Therefore, it is possible to easily carry around the wall. On the other hand, when dry joints are attached to the respective wall panels that form one wall surface, a gap is likely to be formed between these dry joints.
On the other hand, by attaching the dry joint to the wash floor and the bathtub as in the present embodiment, the dry joint is divided into a plurality even when one wall surface is composed of a plurality of wall panels. Therefore, it is possible to reduce the possibility of problems such as water leakage.

Further, since the first end portion 251 of the dry joint 25 is fixed to the wash floor 2, it becomes possible to collectively cover the gaps between the side wall S1 and each of the plurality of wall panels with the dry joint 25. .. Therefore, it becomes possible to more easily perform the construction of the dry joint.
Similarly, since the first end portion 261 of the dry joint 26 is fixed to the bathtub 1, the gap between the side wall S2 and each of the plurality of wall panels can be collectively covered with the dry joint 26. .. Therefore, it becomes possible to more easily perform the construction of the dry joint.

  In addition, the walls (wall panels) that form the bathroom may be piled up during transportation or construction. Therefore, when the dry joint is attached to the wall, the dry joint may be damaged during transportation or construction. In this regard, in the present embodiment, since the dry joint is attached to the washing floor and the bathtub, the possibility that the dry joint is damaged during transportation or construction can be reduced.

  The ends of dry joints 25 and 26 are preferably displaced by deforming these dry joints. When these ends are displaced by deforming the dry joints 25 and 26, the ends of the dry joints can be displaced without providing a special structure to the wash floor 2 and the bathtub 1.

  At this time, it is desirable that the dry joints 25 and 26 are soft. This is because these dry joints are soft and can be easily deformed. Therefore, the work efficiency at the time of construction can be improved.

Further, it is desirable that the dry joints 25 and 26 have elasticity. Since these dry joints have elasticity, when the deformation of the dry joints is released, the gap between the side wall of the concave portion and the wall is naturally covered with the dry joints by the elastic force. Therefore, the work efficiency at the time of construction can be improved.
When the dry joint 25 has elasticity, the second end 252 of the dry joint 25 extends in the direction intersecting the surface of the wall 3 as shown in FIG. 3, the dry joint 25 presses the wall 3 more strongly. Since the dry joint 25 abuts against the wall 3 while pressing it more strongly, a gap is less likely to be created between the dry joint 25 and the wall 3, and the water stoppage by the dry joint 25 can be improved.
Similarly, when the dry joint 26 has elasticity, the second end 262 of the dry joint 26 extends in the direction intersecting the surface of the wall 3 as shown in FIG. The dry joint 26 presses the wall 3 more strongly when the wall 262 is brought into contact with the wall 3. By contacting the dry joint 26 while pressing the wall 3 more strongly, it is difficult to form a gap between the dry joint 26 and the wall 3, and the water stoppage by the dry joint 26 can be improved.

  When the dry joints 25 and 26 have elasticity, it is desirable that at least the side of the dry joints 25 and 26 that comes into contact with the wall 3 is thin. By being thin, even if the dry joints 25 and 26 have elasticity, they can be easily deformed. Therefore, the work efficiency at the time of construction can be improved.

The second end 252 of the dry joint 25 is preferably deformed toward the inside of the wash floor 2 so that the second end 252 is located above the wash floor 2. According to such a construction method, when the state where the dry joint 25 is displaced after the wall 3 is placed is released, the gap between the side wall S1 and the wall 3 can be covered from above by the dry joint 25. Therefore, the state in which the upper surface of the dry joint 25 is inclined downward from the wall 3 toward the washing floor 2 can be more easily realized, and the drainage property on the upper surface of the dry joint 25 can be improved to prevent generation of mold. It becomes possible to suppress.
Similarly, the second end 262 of the dry joint 26 is preferably deformed toward the inside of the bath 1 so that the second end 262 is located above the bath 1. According to such a construction method, when the state where the dry joint 26 is displaced after the wall 3 is placed is released, the gap between the side wall S2 and the wall 3 can be covered from above by the dry joint 26. For this reason, it is possible to more easily realize a state in which the upper surface of the dry joint 26 is inclined downward from the wall 3 toward the bathtub 1, and the drainage property on the upper surface of the dry joint 26 is improved to suppress the generation of mold. It becomes possible to do.

  Further, when fixing the dry joint 25 having the bent portion as shown in FIG. 7, as shown in FIG. 11A, before the skin material 23 and the floor material 21 are bonded together, the dry joint 25 It is desirable to fix the first end 251 of the above to the bottom surface of the skin material 23. By doing so, the first end 251 can be fixed between the skin material 23 and the floor surface material 21 in a state where the bent portion of the dry joint 25 is in contact with the side surface of the skin material 23. Therefore, the first end portion 251 can be more firmly fixed, and a gap can be suppressed from being formed between the dry joint 25 and the side surface of the skin material 23.

  Further, in the present embodiment, the end of the dry joint 25 projects toward the outside of the wash floor 2 in a state where the wall 3 is not placed in the recess 21R and the second end 252 is not displaced. The length L1 of the protruding portion is longer than the gap (distance D1) between the side wall S1 and the steel plate 311. According to such a configuration, when the state where the dry joint 25 is displaced after the wall 3 is placed is released, the dry joint 25 can cover all the gaps, and the waterproofness by the dry joint 25 is improved. be able to.

  On the other hand, when the length L1 is longer than the distance D1, the dry joint 25 and the wall 3 are more likely to contact each other when the wall 3 is placed in the recess 21R. Therefore, the dry joint construction method according to the present embodiment is particularly effective when the length L1 is longer than the distance D1.

Similarly, in a state where the wall 3 is not placed in the recess 1R and the second end 262 is not displaced, the end of the dry joint 26 projects toward the outside of the bath 1 and projects. The length L2 of the portion is longer than the gap (distance D2) between the side wall S2 and the base material 360. According to such a configuration, when the wall 3 is placed and the state where the dry joint 26 is displaced is released, the dry joint 26 can cover all the gaps, and the waterproofness by the dry joint 26 is improved. Can be made
Also in this case, similarly, when the length L2 is longer than the distance D2, the dry joint 26 and the wall 3 are more likely to contact each other when the wall 3 is placed in the recess 1R. Therefore, the dry joint construction method according to the present embodiment is particularly effective when the length L2 is longer than the distance D2.

  In addition, in the above-described embodiment, the case where the washing floor 2 is composed of the support material 22, the floor surface material 21, the cushion material 201, and the skin material 23 has been described, but the present embodiment has such a configuration. It can also be applied to other wash floors. For example, the wash floor may be composed of two members, the support member 22 and the floor surface member 21. In this case, the dry joint 25 is fixed to the outer periphery of the floor material 21.
