A wall panel 37 is provided below the wall panel 34 and the wall panel 35 to connect the bathtub 1 to the wall panel 32 and the wall panel 33. In the bathroom unit shown in FIG. 1, a door DR is provided on the wall panel 33 via a door mounting frame (not shown).

  In addition, the structure of the wall surface material in this invention is not limited to the said wall panels 31-37. For example, the wall panel 31 may be composed of more panels, and the other wall panels 32 to 37 may be composed of a plurality of panels. Moreover, the wall panel 31 may be comprised from one panel.

  A bath apron 9 is provided at the boundary between the bathtub 1 and the washing floor 2 to cover the side face of the bathtub 1 on the washing floor 2 side. The bath apron 9 is provided so as to press a floor material 21 described later.

FIG. 2 is a cross-sectional view illustrating a fitting structure between a wall surface connecting member and a wall panel in the embodiment.
In FIG. 2, the cross section along the direction orthogonal to the in-plane direction of a wall panel is represented.
FIG. 2A illustrates a fitting structure of two wall panels adjacent on the same plane and a wall surface connecting member provided therebetween.
FIG. 2B illustrates a fitting structure of two wall panels that are orthogonal to each other at the corners and a wall surface connecting member provided between them.
In the following description, the wall surface connecting member 50A illustrated in FIG. 2A and the wall surface connecting member 50B illustrated in FIG. 2B are collectively referred to as the wall surface connecting member 50.

  As illustrated in FIG. 2, the wall panel 31 includes a first wall panel 31-1 and a second wall panel 31-2. Each wall panel has a base material and a steel plate provided inside the bathroom with respect to the base material. The base material is formed of gypsum board or the like, and the steel plate is affixed to the surface of the base material inside the bathroom for reinforcement. For example, the first wall panel 31-1 includes a base material 310-1 and a steel plate 311-1. The second wall panel 31-2 includes a base material 310-2 and a steel plate 311-2.

  The wall surface connecting member 50 has a hollow structure in which a thin plate is bent. The left and right folded portions 501 of the wall surface connecting member 50 have elasticity.

  FIG. 2A shows an attached state of the two wall panels 31-1 and 31-2 constituting the wall panel 31. FIG. The left and right side surfaces of the steel plates 311 of the two wall panels 31-1 and 31-2 are provided with elastic folded portions 502-1 and 502-2, respectively.

  In order 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 portions 502-1 and 502-2 are urged in the direction of each other by being fitted so as to push between the left and right folded portions 501. When the folded portions 502-1 and 502-2 are fitted, the two wall panels 31-1 and 31-2 are fixed to the same surface with the wall surface connecting member 50A interposed therebetween.

  FIG. 2B shows an attached state of the wall panel 31-2 and the wall panel 32 constituting the wall panel 31. The steel plate 311-2 of the wall panel 31-2 is provided with a folded portion 502-1 and the steel plate 321 of the wall panel 32 is provided with a folded portion 502-2. The folded portions 502-1 and 502-2 each have elasticity.

  The folded portions 502-1 and 502-2 are fitted so as to push and spread between the left and right folded portions 501. When the folded 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, the folded portion 501 of the wall surface connecting member 50 and the folded portion 502 of each wall panel have elasticity along the plane orthogonal to the wall 3, so that their installation positions are fixed. On the other hand, in the direction along the surface of the wall 3, the position of the wall connecting member 50 is not restricted. For this reason, when each wall panel is fitted in the wall surface connection member 50, it falls downward due to its own weight, and its lower end (a tip portion 311 a described later) comes into contact with the floor material 21.

FIG. 3 is a perspective view illustrating a wall mounting structure in the 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 washing floor 2 are attached to the outer peripheral portion 2 a of the washing floor 2. The wall surface connecting member 50 is fixed to a wall surface fixing member 51 attached in advance by fastening means such as bolts and screws. At this time, the wall surface connecting member 50 may be fixed so that the outer peripheral portion 2a of the floor surface material 21 is pressed downward by the lower end of the wall surface connecting member 50. The wall panels 31 to 35 are fixed by fitting the wall panels to the respective wall surface 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 embodiment.
As illustrated in FIG. 4, the washroom floor 2 includes a floor base material 20 and a skin material 23 disposed on the floor base material 20. The floor base material 20 includes 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 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 is sandwiched between two steel plates, is lightweight and highly rigid, and a fastening member such as a screw can also be used. The support member 22 is provided with a work port so that an operator can go under the floor. After the construction, the work port is covered with a lid 221.

  As will be described later, the floor surface material 21 is provided with an inclined surface for forming a concave shape portion serving as a drain port and a gradient of the upper surface of the washing floor 2. The floor material 21 is made of, for example, a thermoplastic resin. The floor material 21 may be formed of fiber reinforced plastic (FRP). Examples of the thermoplastic resin include foamed polypropylene, foamed polystyrene, foamed polyethylene, and foamed polyurethane.

  A cushion material 201 is provided on the floor surface material 21. For the cushion material 201, for example, a soft material such as polyurethane foam 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 disposed on the outermost surface of the washing floor 2, and a soft sheet material having waterproofness and flexibility is used. In order to improve the design and drainage properties of the surface of the washing floor 2, the skin material 202 can be subjected to uneven processing or a pattern.

A recess is formed on the outer periphery of the floor material 21, and the wall 3 is placed on the 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 washing floor and a part of the wall according to the embodiment.
6 is an enlarged perspective sectional view of a portion B in FIG.
FIG. 7 is an enlarged cross-sectional view of a part of the washing floor and a part of the wall shown in FIG.
FIG. 8 is an enlarged cross-sectional view of a part of the washing floor and a part of the wall shown in FIG.
5 to 7, the support member 22 is omitted.

  As shown in FIGS. 5 to 7, the steel plate 311 extends toward the floor surface material 21, and the tip portion 311 a is bent toward the outside of the washing 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 the recess. On the guide piece 27, the front-end | tip part 311a is mounted via packing PK1. The floor surface material 21 is pressed downward by the weight of the wall 3. The tip of the tip 311 a is fixed by a guide piece 27. By doing so, a shift in the relative positional relationship between the washing floor 2 and the wall 3 is suppressed.

  Among the side surfaces of the recess 21R, a caulking material CK1 as a deformation suppressing means is provided in a gap between the side surface S1 located inside the washing floor 2 and the wall 3 (wall panel 31). 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. The second end 252 is in contact with the wall panel 31.

  As shown in FIG. 8, the dry joint 25 has an inclined portion 25a that covers the caulking material CK1. The inclined portion 25a is deformed so that, for example, one end is along the direction orthogonal to the first side surface S1 and the other end is along the surface of the wall 3. For this reason, the upper surface of the inclined portion 25 a is inclined upward from the washing floor 2 toward the wall 3.

  At least a part of the lower surface of the inclined portion 25a is in contact with the caulking material CK1. At least a part of the lower surface of the inclined portion 25a may be bonded to the caulking material CK1. At this time, the inclined portion 25a is directly bonded to the caulking material CK1, for example, without using an adhesive or a double-sided tape. Since the lower surface of the inclined portion 25a is in contact with the caulking material CK1, the inclined portion 25a is supported by the caulking material CK1 from below. Thereby, the downward deformation | transformation of the inclination part 25a is suppressed.

  At least the inclined portion 25a of the dry joint 25 has elasticity and is at least one of soft and thin-walled. The entire dry joint 25 has elasticity and may be at least one of soft and thin-walled.

For the caulking material CK1, for example, silicone is used.
The dry joint 25 includes 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, or polyamide resins such as nylon, fluorine. Resin, etc. can be used. By using these materials, elasticity and softness can be imparted to the dry joint 25.

FIG. 9 is an enlarged plan view of the vicinity of the recess of the washing floor before the wall panel is installed.
10 is a cross-sectional view taken along line AA ′ of FIG.
In FIG. 9 and FIG. 10, the wall panel 31 to be placed thereafter is indicated by a broken line.

  As shown in FIGS. 9 and 10, when the wall panel 31 is not installed, the dry joint 25 extends in the horizontal direction and protrudes toward the outside of the washing floor 2. At this time, the length L1 of the portion protruding on the recess 21R is longer than the distance D1 between the side surface S1 and the steel plate 311 in a state where the wall panel is installed. For this reason, in the state in which the wall panel 31 is installed, the second end portion 252 of the dry joint 25 is in contact with the steel plate 311 and bends so that the upper surface of the dry joint 25 is downward from the steel plate 311 toward the skin material 23. And an inclined portion 25a appears.

Here, the construction method of the dry joint of the bathroom which concerns on embodiment is demonstrated using FIGS. 11-15.
FIGS. 11-15 is sectional drawing showing the construction method of the dry joint of the bathroom which concerns on embodiment.
First, as shown in FIG. 11A, 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, it may be fixed with adhesive, heat welding, staples, or the like.

  Next, as shown in FIG. 11B, the skin material 23 is bonded to the surface of the floor material 21 in which the guide piece 27 is provided in the recess 21 </ b> R. At this time, the skin material 23 is bonded to the floor material 21 so that a portion of the dry joint 25 fixed to the skin material 23 is sandwiched between the skin material 23 and the floor material 21.

  A state in which the skin material 23 is arranged on the floor material 21 is shown in FIG. As shown in FIG. 12A, 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. 12B and 13A, the second end portion 252 of the dry joint 25 is deformed upward and is 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 FIG. 13B and FIG. 14A, the wall panel 31 is moved downward from above the floor material 21 and the skin material 23 to the recess 21 </ b> R, and Placed on. At this time, since the second end 252 of the dry joint 25 is fixed to the skin material 23, contact between the wall panel 31 and the dry joint 25 can be avoided.

  Next, as shown in FIG. 14B and FIG. 15A, the caulking material CK <b> 1 is filled between the side surface S <b> 1 and the steel plate 311.

  Finally, as shown in FIG. 15B, the deformation of the second end 252 of the dry joint 25 is released. At this time, since the dry joint 25 has elasticity, by releasing the deformation of the second end 252 of the dry joint 25, the original shape shown in FIG. At that time, the caulking material CK <b> 1 is covered with the dry joint 25, and the tip of the dry joint 25 comes into contact with the steel plate 311. As already described, since the length L1 of the protruding portion of the dry joint 25 is longer than the distance D1, the dry joint 25 comes into contact with the steel plate 311 in a bent state, and the upper surface of the dry joint 25 is separated from the skin material 23. It inclines upward toward the steel plate 311.

  At this time, an inclined portion 25 a is formed in the dry joint 25. 14B, when the deformation of the dry joint 25 is released by filling the caulking material CK1 so that the upper end of the caulking material CK1 is located above the upper surface of the skin material 23, The lower surface of the inclined portion 25a can be brought into contact with the caulking material CK1. By curing the caulking material CK1 in this state, it is possible to directly bond the lower surface of the inclined portion 25a and the caulking material CK1 without using an adhesive or a double-sided tape.

  In the above description, the wall panel 31 has been described as an example, but the other wall panels 32, 33, and 37 are also installed on the washing floor 2 in the same manner.

Next, the structure in the outer periphery of the bathtub 1 is demonstrated concretely using FIG. 16 and FIG.
FIG. 16 is an enlarged cross-sectional view of a part of the bathtub and a part of the wall according to the embodiment.
FIG. 17 is an enlarged cross-sectional view of a part of the bathtub and a part of the wall shown in FIG.
As shown in FIG. 16, the wall panel 36 includes a base material 360 and a back plate 361. A recess 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 recess 1R via the packing PK2.

  Base material 360 opposes side surface S2 located in the inner side direction of bathtub 1 among the side surfaces of recess 1R. A joint member is provided in the gap with the side S2 steel plate 311. The joint member includes a caulking material CK <b> 2 and a dry joint 26. The caulking material CK2 is filled in a gap between the side surface S2 and the base material 360. 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 surface S2. The second end 262 covers the caulking material CK2, and its lower surface is in contact with the caulking material CK2.

  As shown in FIG. 17, the dry joint 26 has an inclined portion 26a that covers the caulking material CK2. The inclined portion 26a includes a first end 261 on the bathtub 1 side and a second end 262 on the wall 3 (wall panel 36) side. For example, the inclined portion 26 a is curved so that the first end 261 is along the direction orthogonal to the side surface S <b> 2 and the second end 262 is along the surface direction of the wall 3. Further, the second end 262 of the dry joint 26 abuts against the wall 3 so that the upper surface of the inclined portion 26 a is inclined upward from the bathtub 1 toward the wall 3.

  At least a part of the lower surface of the inclined portion 26a is in contact with the caulking material CK2. At least a part of the lower surface of the inclined portion 26a may be bonded to the caulking material CK2. At this time, the inclined portion 26a is directly bonded to the caulking material CK2, for example, without using an adhesive or a double-sided tape. Since the lower surface of the inclined portion 26a is in contact with the caulking material CK2, the inclined portion 26a is supported by the caulking material CK1 from below. Thereby, the downward deformation | transformation of the inclination part 26a is suppressed.

  At least the inclined portion 26a of the dry joint 26 has elasticity and is at least one of soft and thin-walled. The entire dry joint 26 has elasticity and may be at least one of soft and thin-walled. The dry joint 26 can be made of the same material as the dry joint 25. Moreover, the same material as the caulking material CK1 can be used for the caulking material CK2.

In FIG. 18 and FIG. 19, the wall panel 36 to be placed thereafter is indicated by a broken line.

  As shown in FIGS. 18 and 19, when the wall panel 36 is not installed, the dry joint 26 extends in the horizontal direction and protrudes toward the outside of the bathroom. At this time, the length L2 of the portion protruding on the recess 1R is longer than the distance D2 between the side surface S2 and the wall panel 36 in a state where the wall panel is installed. For this reason, in the state in which the wall panel is installed, the second end portion 262 of the dry joint 26 abuts against the base material 360 and bends, so that the upper surface of the dry joint 26 is lowered from the base material 360 toward the bathtub 1. Inclined 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 washing 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 surface S1 of the recess 1R. The dry joint 26 is fixed by, for example, a double-sided tape or an adhesive. Alternatively, it may be fixed by heat welding or staples.

  Next, the second end portion 262 of the dry joint 26 is deformed upward and is temporarily fixed to the bathtub 1 with, for example, a masking tape. Subsequently, the wall panel 36 is moved and placed from above the bathtub 1 toward the recess 1R. 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, contact between the wall panel 36 and the dry joint 26 can be avoided.

  Next, the caulking material CK <b> 2 is filled between the side surface S <b> 2 and the wall panel 36. At this time, the caulking material CK <b> 2 is filled so that, for example, the upper end is located above the upper end of the bathtub 1. Thereafter, when the fixing of the second end portion 262 of the dry joint 26 is released, the caulking material CK2 is covered with the dry joint 26, and the tip of the dry joint 26 comes into contact with 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 against the wall panel 36 in a bent state, and an inclination is formed on the upper surface of the dry joint 26.

  In the above description, the wall panel 36 has been described as an example, but the other wall panels 34 and 35 are installed on the washing floor 2 in the same manner.

(Modification)
Next, a modification of the embodiment will be described with reference to FIGS.
FIG. 20 is an enlarged cross-sectional view of a part of the washing floor and a part of the wall according to the modification of the embodiment.
FIG. 21 is an enlarged cross-sectional view of a part of a bathtub and a part of a wall according to a modification of the embodiment.

  As shown in FIG. 20, the caulking material CK1 may not be provided between the side surface S1 and the wall 3 (wall panel 31). In this case, the second end 252 contacts the wall 3 and is fixed to the wall 3 by the adhesive 28. The first end portion 251 of the dry joint 25 is fixed to the washing floor 2, and the second end portion 252 is fixed to the wall 3, so that the downward deformation of the inclined portion 25a is suppressed. That is, in this modification, the adhesive 28 functions as a deformation suppressing unit.

  The second end 252 of the dry joint 25 may be fixed to the wall 3 by means other than the adhesive 28. That is, the deformation suppressing means is not limited to the adhesive 28. For example, the second end portion 252 of the dry joint 25 may be fixed to the wall 3 with a double-sided tape, heat welding, staple, or the like instead of the adhesive 28.

  Similarly, as shown in FIG. 21, the caulking material CK2 may not be provided between the side surface S2 and the wall 3 (wall panel 36). In this case, the second end 262 abuts against the wall 3 and is fixed to the wall 3 with an adhesive 29 as a deformation suppressing means. Since the first end 261 of the dry joint 26 is fixed to the bathtub 1 and the second end 262 is fixed to the wall 3, the downward deformation of the inclined portion 26 a is suppressed. Similarly to the dry joint 25, the second end portion 262 of the dry joint 26 may be fixed to the wall 3 with a double-sided tape, heat welding, staple, or the like instead of the adhesive 29, for example.

  In addition, although embodiment mentioned above demonstrated the case where the washing floor 2 was comprised from the support material 22, the floor surface material 21, the cushioning material 201, and the skin material 23, this embodiment is such a structure. It can also be applied to other washroom floors. For example, the washroom floor may be composed of two of a support material 22 and a floor surface material 21. In this case, the dry joint 25 is fixed to the outer periphery of the floor material 21.

  According to the embodiment described above, the dry joint 25 has only the first end 251 fixed to the washing floor 2 and the second end 252 is in contact with the wall 3. For this reason, it is possible to fix the dry joint 25 to the wash floor 2 before placing the wall 3 in the recess 21R. Therefore, it is possible to attach the dry joint 25 to the washing floor 2 in advance before construction. For example, by attaching the dry joint 25 to the washing floor 2 at the manufacturing site, it is not necessary for the builder to attach the dry joint 25 at the construction site, so the dry joint 25 is easily detached. It is possible to suppress construction errors such as the occurrence of water leakage due to misalignment or the displacement of the mounting position of the dry joint 25.

  Moreover, since the dry joint 25 has the inclination part 25a which covers the clearance gap between 1st side surface S1 and the wall 3, the inflow of the water to a clearance gap can be suppressed. Further, since the inclined portion 25a is inclined upward from the washing floor 2 toward the wall 3, the drainage from the wall 3 toward the washing floor 2 is enhanced, and the generation of mold on the upper surface of the dry joint 25 is suppressed. can do. Furthermore, since it has deformation suppressing means (caulking material CK1 or adhesive 28), even when an external force is applied downward with respect to the dry joint 25, the deformation of the dry joint 25 is suppressed, and the drainage in the dry joint 25 is performed. It becomes possible to suppress the fall of property.

  At this time, the deformation suppressing means (caulking material CK1) is provided between the first side surface S1 and the wall 3 below the inclined portion 25a, and supports the inclined portion 25a from below, thereby further increasing the inclined portion. It becomes possible to suppress the downward deformation of 25a and the decrease in drainage at the dry joint 25. Furthermore, by providing the deformation suppressing means below the inclined portion 25a, it is difficult for the deformation suppressing means to enter the view of the user of the bathroom 100, and it is possible to suppress a decrease in the beauty of the bathroom 100.

  Further, since the deformation suppressing means is the caulking material CK1, the inflow of water into the gap between the first side surface S1 and the wall 3 is further suppressed by two of the dry joint 25 and the caulking material CK1, and the water stoppage is improved. While making it dry, the drainage fall by a dry joint deform | transforming can be suppressed.

  Here, at least a part of the lower surface of the inclined portion 25a is directly bonded to the caulking material CK1 without using an adhesive or a double-sided tape, thereby forming a gap between the inclined portion 25a and the caulking material CK1. The possibility of being reduced can be reduced, and the deformation of the dry joint can be more reliably suppressed. Moreover, generation | occurrence | production of the mold by the inflow of the water to the said clearance gap can be suppressed.

  When fixing the dry joint 25 having a bent portion as shown in FIG. 7, as shown in FIG. 11A, the dry joint 25 is bonded before the skin material 23 and the floor material 21 are bonded together. It is desirable to fix the first end portion 251 to the bottom surface of the skin material 23. By doing so, the first end portion 251 can be fixed between the skin material 23 and the floor material 21 in a state where the bent portion of the dry joint 25 is in contact with the side surface 23S of the skin material 23. For this reason, while fixing the 1st edge part 251 more firmly, it can suppress that a clearance gap produces between the dry joint 25 and the side surface 23S of the skin material 23. FIG.

  Further, when the dry joint 25 has elasticity, the second end 252 of the dry joint 25 extends in a direction intersecting the surface of the wall 3 as shown in FIG. Is brought into contact with the wall 3, the dry joint 25 presses the wall 3 more strongly. When the dry joint 25 abuts against the wall 3 in a more strongly pressed state, a gap is hardly formed between the dry joint 25 and the wall 3, and water stoppage by the dry joint 25 can be improved.

  Similarly for the bathtub 1, the dry joint 26 has only the first end 261 fixed to the bathtub 1, and the second end 262 is in contact with the wall 3. For this reason, it is possible to fix the dry joint 26 to the bathtub 1 before placing the wall 3 in the recess 1R. Therefore, it becomes possible to attach the dry joint 26 to the bathtub 1 before construction. For example, by attaching the dry joint 26 to the bathtub 1 at the manufacturing site, it becomes unnecessary for the installer to attach the dry joint 26 at the construction site, so that the dry joint 26 may be easily detached. In addition, it is possible to suppress construction mistakes such as water leakage due to a shift in the mounting position of the dry joint 26.

  Moreover, since the dry joint 26 has the inclined portion 26a that covers the gap between the second side surface S2 and the wall 3, the inflow of water into the gap can be suppressed. In addition, since the inclined portion 26a is inclined upward from the bathtub 1 toward the wall 3, the drainage performance from the wall 3 toward the bathtub 1 is enhanced, and the generation of mold on the upper surface of the dry joint 26 is suppressed. Can do. Furthermore, since it has the deformation | transformation suppression means (caulking material CK2 or the adhesive agent 29) which suppresses the downward deformation | transformation of the inclination part 26a, even when an external force is applied toward the downward direction with respect to the dry joint 26, the dry joint 26 It is possible to reduce the possibility that a dent will be formed on the surface and to suppress a decrease in drainage at the dry joint 26.

  At this time, the deformation suppressing means (caulking material CK2) is provided between the second side surface S2 and the wall 3 below the inclined portion 26a, and supports the inclined portion 26a from below, thereby further increasing the inclined portion. It becomes possible to suppress the deformation | transformation to the downward direction of 26a, and the fall of the drainage property in the dry joint 26. FIG. Furthermore, since the deformation suppressing means is provided below the inclined portion 26a, it is difficult for the deformation suppressing means to enter the field of view of the user of the bathroom 100, and it is possible to suppress a decrease in the beauty of the bathroom 100.

  In addition, since the deformation suppressing means is the caulking material CK2, the inflow of water into the gap between the second side surface S2 and the wall 3 is further suppressed by two of the dry joint 26 and the caulking material CK2, and the water stoppage is improved. While making it dry, the drainage fall by a dry joint deform | transforming can be suppressed.

  Here, at least a part of the lower surface of the inclined portion 26a is directly bonded to the caulking material CK2 without using an adhesive or a double-sided tape, thereby forming a gap between the inclined portion 26a and the caulking material CK2. The possibility of being reduced can be reduced, and the deformation of the dry joint can be more reliably suppressed. Moreover, generation | occurrence | production of the mold by the inflow of the water to the said clearance gap can be suppressed.

  Further, when the dry joint 26 has elasticity, as shown in FIG. 19, the second end 262 of the dry joint 26 extends in a direction intersecting the surface of the wall 3, and thus the second end 262. Is brought into contact with the wall 3, the dry joint 26 presses the wall 3 more strongly. When the dry joint 26 comes into contact with the wall 3 being pressed more strongly, it is difficult to form a gap between the dry joint 26 and the wall 3, and water stoppage by the dry joint 26 can be improved.

  In the bathroom according to the present embodiment, the dry joint 25 is fixed to the washing floor 2 or the wall 3 and the dry joint 26 is fixed to the bathtub 1 or the wall 3 before the wall 3 is placed. . According to such a configuration, the dry joints 25 and 26 can be attached in advance before the bathroom is assembled. By attaching the dry joints 25 and 26 at the manufacturing site of the bathtub 1, the washing floor 2, and the wall 3, it is not necessary for the installer to attach the dry joint at the construction site. For this reason, it is not necessary to leave the installation of dry joints to the contractor's hands, and it is possible to suppress the occurrence of problems such as construction with the dry joints easily coming off or leakage due to displacement of the dry joint attachment It becomes possible to do.
