[0008] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. The remodeling fixture 1 according to this embodiment is a bathroom door as a remodeling fixture for remodeling (renovation) in which a new frame 3 is attached to an existing frame 2 in a state where the existing frame 2 is attached to an opening of a building skeleton 100.

[0009] The existing frame 2 is constructed by assembling the existing upper frame 21, the existing lower frame 22, and a pair of existing vertical frames 23, 24 into a rectangle on all four sides. The new upper frame 31, the new lower frame 32, and a pair of new vertical frames 33, 34 that constitute the new frame 3 are in a disassembled state without being assembled on all four sides before installation, and are individually attached to the existing upper frame 21, the existing lower frame 22, and a pair of existing vertical frames 23, 24, respectively, and assembled into a rectangle on all four sides. In the renovated fitting 1 constructed by this construction method, there is no need to assemble the new frame 3 on all four sides in advance, which provides excellent workability.

[0010] In the following explanation, the prospective direction is the direction from the bathroom to the dressing room in the renovated fitting 1, or the opposite direction. The prospective direction is the direction along the surface direction of the surface material in the renovated fitting 1, and is the direction perpendicular to the prospective direction. In the drawings, the bathroom side of the renovated fitting 1 is referred to as the "bathroom side X1", and the dressing room side of the renovated fitting 1 is referred to as the "dressing room side X2". The horizontal direction when the renovated fitting 1 is viewed from the front is referred to as the "left-right direction". The direction toward the center of the renovated fitting 1 when viewed from the front is referred to as the "inward direction", and the direction away from the center of the renovated fitting 1 is referred to as the "outward direction".

[0011] As shown in Figures 1, 2, etc., the existing frame 2 is formed by assembling four frame components, namely, an existing upper frame 21, an existing lower frame 22, and a pair of existing vertical frames 23, 24 on the left and right, in a rectangular shape, and is attached to the inside of an opening in the building structure 100 before renovation.

[0012] As shown in FIG. 2, a spotting member 101 is disposed on the dressing room side of the existing frame 2. The spotting member 101 is attached to the upper side and left and right sides of the inner periphery of the opening of the building structure 100, and is disposed in contact with or adjacent to the end face of the dressing room side X2 of the existing frame 2. The spotting member 101 is formed of wood, resin, or aluminum, and has a height approximately equal to the protruding height of the existing frame 2 from the inner periphery of the opening of the building structure 100, covering the spotting surface of the dressing room side X2 of the existing frame 2. The gap between the four-sided assembled existing frame 2 and the wall material 102 provided on the bathroom side X1 of the building structure 100 is sealed around the four sides with wet sealant 104.

[0013] As shown in Fig. 2, the existing upper frame 21 is positioned above the opening of the building structure 100. On the dressing room side of the existing upper frame 21, the upper part of the spotting member 101 is positioned in contact with or close to the existing upper frame 21. The gap between the existing upper frame 21 and the upper part of the wall material 102 provided on the bathroom side X1 of the building structure 100 is sealed with a wet sealant 104. As shown in Fig. 4, the existing upper frame 21 has a horizontal portion 211 and a vertical portion 212.

[0014] As shown in Fig. 2, the existing sill 22 is placed and fixed to the bottom of the opening in the building skeleton 100. A floor material 103 is placed in contact with or adjacent to the existing sill 22 on the dressing room side of the existing sill 22. The gap between the existing sill 22 and the bottom of the wall material 102 provided on the bathroom side X1 of the building skeleton 100 is sealed with a wet sealant 104. As shown in Fig. 5, the existing sill 22 has a horizontal portion 221 and a vertical portion 222.

[0015] As shown in Fig. 3, the existing vertical frames 23, 24 are arranged and fixed to the left and right vertical portions of the opening of the building skeleton 100. On the dressing room side of the existing vertical frames 23, 24, the left and right portions of the sight member 101 are arranged in contact with or close to the existing vertical frames 23, 24. The gaps between the existing vertical frames 23, 24 and the left and right portions of the wall material 102 provided on the bathroom side X1 of the building skeleton 100 are sealed with wet sealant 104. As shown in Fig. 6, the existing vertical frame 23 has a projection portion 231 and a projection portion 232. As shown in Fig. 7, the existing vertical frame 24 has a projection portion 241 and a projection portion 242.

[0016] The new frame 3 has a new upper frame 31 fixed to the underside of the existing upper frame 21, a new lower frame 32 fixed to the upper side of the existing lower frame 22, and new vertical frames 33, 34 fixed to the inside of the left and right existing vertical frames 23, 24. The new upper frame 31, the new lower frame 32, and the new vertical frames 33, 34 are all composed of long members.

[0017] More specifically, the new upper frame 31 has a length sufficient to cover the entire lower surface of the existing upper frame 21 in the rectangularly framed existing frame 2. The new lower frame 32 has a length sufficient to cover the entire upper surface of the existing lower frame 22 in the rectangularly framed existing frame 2. The new vertical frames 33, 34 have a length sufficient to cover the entire inner surfaces of the left and right existing vertical frames 23, 24 in the rectangularly framed existing frame 2.

[0018] 4, the new upper frame 31 is formed in an L-shape having a horizontal portion 311 and a vertical portion 312 in a cross section in the longitudinal direction of the new upper frame 31. The horizontal portion 311 faces the horizontal portion 211 of the existing upper frame 21, and has a guide rail 311a that protrudes downward to guide the new folding door 5.

[0019] The end of the horizontal section 311 on the bathroom side X1 is formed in a T-shape with a rib 311b as a downward extension that extends vertically downward. The lower end of the rib 311b is located below the base side part of the horizontal section 311 connected to the rib 311b. This makes it possible for water droplets adhering to the rib 311b to drip from the lower end of the rib 311b along the rib 311b, and as a result, it is possible to prevent the water droplets from flowing into the existing frame 2, the new frame 3, or along the horizontal section 311 to the changing room side X2.

[0020] Between the upper end of the rib 311b and the horizontal portion 211, a dry sealing member 214, which is a component made of rubber, resin, or the like, is provided. The dry sealing member 214 abuts against the upper end of the rib 311b and the horizontal portion 211, and the dry sealing member 214 provides a liquid-tight seal between the upper end of the rib 311b and the horizontal portion 211. As a result, liquid-tight sealing can be achieved simply by disposing the dry sealing member 214, which is a component serving as a seal member, at this position, so that a process of filling and drying a fluid sealant to achieve liquid-tight sealing can be omitted, and construction time can be shortened.

[0021] Furthermore, a dry sealing member 215, which is a component made of rubber, resin, or the like, is provided between the facing surface of the vertical portion 312 on the changing room side X2 and the lower end of the vertical portion 212. The dry sealing member 215 provides a liquid-tight seal between the vertical portions 312 and 212. This allows for a liquid-tight seal simply by placing the dry sealing member 215, which is a component serving as a seal member, in this position, thereby eliminating the need for a process of filling and drying a fluid sealant to provide a liquid-tight seal, and thus shortening the construction time.

[0022] 5, the new lower frame 32 is formed in an L-shape having a horizontal portion 321 and a vertical portion 322 in a cross-sectional view in the longitudinal direction of the new lower frame 32. The horizontal portion 321 faces the horizontal portion 221 of the existing lower frame 22 and has a guide rail 321a that protrudes upward and guides the new folding door 5.

[0023] The portion of the horizontal section 321 on the bathroom side X1 above the guide rail 321a has an inclined surface 321c that gently slopes downward toward the bathroom side X1. This allows water droplets that fall on the inclined surface 321c to flow along the inclined surface 321c to the bathroom side X1. This makes it possible for water droplets that fall on the inclined surface 321c to be easily drained to the bathroom side X1, improving drainage performance.

[0024] The end of horizontal part 321 on the bathroom side X1 is formed in an L shape, with rib 321b as a downward extension that extends vertically downward. The lower end of rib 321b is located below the base side part of horizontal part 321 connected to rib 321b. This allows water droplets that have flowed up to rib 321b to flow along rib 321b to the lower end of rib 321b, and as a result, water droplets on rib 321b can be easily drained to the bathroom side X1, improving drainage performance.

[0025] Between the lower end of the rib 321b and the horizontal portion 221, a dry sealing member 224, which is a component made of rubber, resin, or the like, is provided. The dry sealing member 224 abuts against the lower end of the rib 321b and the horizontal portion 221, and the dry sealing member 224 provides a liquid-tight seal between the lower end of the rib 321b and the horizontal portion 221. As a result, liquid-tight sealing can be achieved simply by disposing the dry sealing member 224, which is a component serving as a seal member, at this position, so that a process of filling and drying a fluid sealant to achieve liquid-tight sealing can be omitted, and construction time can be shortened.

[0026] Furthermore, a dry sealing member 225, which is a component made of rubber, resin, or the like, is provided between the upper end of the vertical portion 322 and the upper end of the vertical portion 222 in the up-down direction. The dry sealing member 225 provides a liquid-tight seal between the vertical portion 322 and the vertical portion 222. This allows for a liquid-tight seal simply by disposing the dry sealing member 225, which is a component serving as a seal member, at this position, thereby eliminating the need for a process of filling and drying a fluid sealant to provide a liquid-tight seal, and thus enabling the construction time to be shortened.

[0027] 6, the new vertical frame 33 is formed in an L-shape having a projection portion 331 and a projection portion 332 in a cross-sectional view in the longitudinal direction of the new vertical frame 33. The projection portion 331 faces the projection portion 231 of the existing vertical frame 23.

[0028] The end of the bathroom side X1 of the projection part 331 has a rib 331b extending outward in the projection direction, and is formed in an L-shape. Between the end of the rib 331b on the outer side in the projection direction and the projection part 231, a dry sealing member 234, which is a part made of rubber, resin, etc., is provided. The dry sealing member 234 abuts against the end of the rib 331b on the outer side in the projection direction and the projection part 231, and the dry sealing member 234 seals the gap between the end of the rib 331b on the outer side in the projection direction and the projection part 231 in a liquid-tight manner. As a result, it is possible to seal liquid-tightly just by disposing the dry sealing member 234, which is a part of a sealing member, at this position, so that the process of filling and drying a fluid sealant to seal liquid-tightly can be omitted, and the construction time can be shortened.

[0029] Furthermore, a dry sealing member 235, which is a component made of rubber, resin, or the like, is provided between the facing surface of the facing portion 332 on the changing room side X2 and the end portion inward in the facing direction of the facing portion 232. The dry sealing member 235 provides a liquid-tight seal between the facing portion 332 and the facing portion 232. This allows for a liquid-tight seal simply by placing the dry sealing member 235, which is a component serving as a seal member, in this position, thereby eliminating the need for a process of filling and drying a fluid sealant to provide a liquid-tight seal, and thus shortening the construction time.

[0030] 7, the new vertical frame 34 is formed in an L-shape having a projection portion 341 and a projection portion 342 in a cross-sectional view in the longitudinal direction of the new vertical frame 34. The projection portion 341 faces the projection portion 241 of the existing vertical frame 24.

[0031] The end of the bathroom side X1 of the projection part 341 has a rib 341b extending outward in the projection direction, and is formed in an L-shape. Between the end of the rib 341b on the outer side in the projection direction and the projection part 241, a dry sealing member 244, which is a part made of rubber, resin, etc., is provided. The dry sealing member 244 abuts against the end of the rib 341b on the outer side in the projection direction and the projection part 241, and the dry sealing member 244 seals the gap between the end of the rib 341b on the outer side in the projection direction and the projection part 241 in a liquid-tight manner. As a result, it is possible to seal liquid-tightly just by disposing the dry sealing member 244, which is a part of a sealing member, at this position, so that the process of filling and drying a fluid sealant to seal liquid-tightly can be omitted, and the construction time can be shortened.

[0032] Furthermore, a dry sealing member 245, which is a component made of rubber, resin, or the like, is provided between the facing surface of the facing portion 342 on the changing room side X2 and the end portion inward in the facing direction of the facing portion 242. The dry sealing member 245 provides a liquid-tight seal between the facing portion 342 and the facing portion 242. This allows for a liquid-tight seal simply by placing the dry sealing member 245, which is a component serving as a seal member, in this position, thereby eliminating the need for a process of filling and drying a fluid sealant to provide a liquid-tight seal, and thus shortening the construction time.

[0033] 8, a dry sealing member 346, which is a part made of rubber, resin, or the like, is disposed at the butt portion between the new lower frame 32 and the new vertical frame 34. A dry sealing member similar to the dry sealing member 346, or a dry sealing member having a symmetrical shape to the dry sealing member 346, is also disposed at the butt portion between the new lower frame 32 and the new vertical frame 33, the butt portion between the new upper frame 31 and the new vertical frame 33, and the butt portion between the new upper frame 31 and the new vertical frame 34. Only the dry sealing member 346 will be described below, and descriptions of the other dry sealing members will be omitted.

[0034] As shown in Figures 9 and 10, the dry sealing member 346 has a plate-shaped clamped portion 346b formed in an L-shape and a plate-shaped end cover portion 346a extending from the entire upper edge of the clamped portion 346b toward the center of the new lower frame 32. A gap slightly narrower than the thickness of the clamped portion 346b is formed between the new lower frame 32 and the new vertical frame 34 at the butt portion between the new lower frame 32 and the new vertical frame 34. The clamped portion 346b is inserted and positioned in this gap, which is a position sandwiched between the new lower frame 32 and the new vertical frame 34, at the butt portion between the new lower frame 32 and the new vertical frame 34. The end covering portion 346a is positioned so as to cover the visible surface and upper surface of the bathroom side X1 of the end portion of the horizontal portion 321 of the newly installed lower frame 32, and the visible surface and upper surface of the bathroom side X1 of the end portion of the vertical portion 322.

[0035] As a result, simply by placing the dry sealing member 346, which is a sealing member component, in this position, it becomes possible to achieve a liquid-tight seal, which eliminates the need for the process of filling and drying a fluid sealing material to achieve a liquid-tight seal, thereby enabling the construction time to be shortened.

[0036] As shown in Figures 1 to 3, the newly installed folding door 5 has two sliding doors 5a, 5b, each of which is made of a resin panel separated into upper and lower parts by middle bars 57, 58, and is attached between the door end frame 51 and the middle frame 52 and between the hanging frame 53 and the middle frame 52 via auxiliary frames 54, 55. Each auxiliary frame 54, 55 is rotatably supported by the middle frame 52. This allows each sliding door 5a, 5b to be foldably attached to the middle frame 52. A handle 58a extending parallel to the middle frame 58 is fixed to the middle frame 58.

[0037] The above-mentioned dry sealing member 214, dry sealing member 215, dry sealing member 224, dry sealing member 225, dry sealing member 234, dry sealing member 235, dry sealing member 244, and dry sealing member 245 are installed in the above-mentioned positions by, for example, any of the following three methods.

[0038] That is, in the first method, first, the new upper frame 31, the new lower frame 32, and the new vertical frames 33 and 34 are fixed and attached to the existing upper frame 21, the existing lower frame 22, and the existing vertical frames 23 and 24, respectively. Then, the dry sealing members 214 and 215 are press-fitted between the new upper frame 31 and the existing upper frame 21. This is the first method.

[0039] In the second method, first, the dry sealing members 214 and 215 are attached to the existing upper frame 21 with double-sided tape. In addition, the dry sealing members 224 and 225 are attached to the existing lower frame 22 with double-sided tape. In addition, the dry sealing members 234 and 235 are attached to the existing vertical frame 23 with double-sided tape. In addition, the dry sealing members 244 and 245 are attached to the existing vertical frame 24 with double-sided tape.

[0040] Next, the new upper frame 31 is abutted against the dry sealing members 214 and 215. Also, the new lower frame 32 is abutted against the dry sealing members 224 and 225. Also, the new vertical frame 33 is abutted against the dry sealing members 234 and 235. Also, the new vertical frame 34 is abutted against the dry sealing members 244 and 245. This is the second method.

[0041] As a third method, first, the dry sealing members 214 and 215 are attached in advance to the new upper frame 31. Also, the dry sealing members 224 and 225 are attached in advance to the new lower frame 32. Also, the dry sealing members 234 and 235 are attached in advance to the new vertical frame 33.
