[0035] 4, the new upper frame 31 is attached to the inner periphery side (below the upper frame attachment body 41) of the upper frame attachment body 41 via a spacer member 316. The new upper frame 31 is placed on the lower surface of the spacer member 316 with the plate-shaped spacer member 316 sandwiched between the new upper frame 31 and the lower surface of the indoor / outdoor direction extension plate 411 of the upper frame attachment body 41.

[0036] The spacer member 316 is composed of one or more sheets. The thickness of the sheets constituting the spacer member 316 and the number of layers of the sheets are appropriately set according to the size of the gap between the upper frame attachment body 41 and the newly installed upper frame 31, etc. Depending on the size of the gap between the upper frame attachment body 41 and the newly installed upper frame 31, the spacer member 316 may not be provided.

[0037] The newly installed upper frame 31 is divided into two in the prospective direction, an outdoor frame member 311 and an indoor frame member 312. The outdoor frame member 311 and the indoor frame member 312 are both metal frame members, and are each made of extruded shapes extruded in the longitudinal direction from a metal material such as aluminum. The outdoor frame member 311 and the indoor frame member 312 are integrally connected by a connecting member 313. The connecting member 313 is made of a material having thermal insulation properties such as resin, and blocks the transfer of heat from the outdoor frame member 311 to the indoor frame member 312 in the newly installed upper frame 31.

[0038] The new upper frame 31 has a pair of guide rails 314a, 314b for the two shoji screens 71, 72 that are placed inside the new frame 3, and a guide rail 314c for the screen door 73 that is placed on the outermost side X1 of the new frame 3. The guide rails 314b, 314c are disposed on the exterior frame member 311 and protrude downward. The guide rail 314a is disposed adjacent to the connecting member 313 in the interior frame member 312 and protrudes downward. The guide rails 314a, 314b, 314c extend over the entire length of the new upper frame 31 in the longitudinal direction.

[0039] As shown in Fig. 4, the outdoor frame member 311 has a hollow portion 3111 having a substantially rectangular cross section that extends from a portion where the guide rail 314b is disposed to the connecting member 313. The indoor frame member 312 has a hollow portion 3121 having a substantially rectangular cross section that extends from the connecting member 313 toward the indoor side X2. An upper surface 311a of the outdoor frame member 311 corresponding to the hollow portion 3111 and an upper surface 312a of the indoor frame member 312 corresponding to the hollow portion 3121 are both flat surfaces and are arranged flush with each other in the projection direction of the newly installed upper frame 31. The connecting member 313 does not protrude above these upper surfaces 311a, 312a.

[0040] The outdoor frame member 311 has an outdoor extension 3112 integrally therewith, which extends toward the outdoor side X1 at a position lower than the upper surface 311a of the outdoor frame member 311. When the new upper frame 31 is attached to the inner periphery of the existing upper frame 21, the outdoor extension 3112 is the lowest part of the new upper frame 31. The outdoor extension 3112 is disposed at the end of the new upper frame 31 on the outdoor side X1. Specifically, the outdoor extension 3112 is disposed between the guide rails 314b and 314c. The outdoor extension 3112 also serves as a drainage channel that directs rainwater that has infiltrated the upper surface of the new upper frame 31 in the viewing direction without allowing it to flow into the indoor side X2.

[0041] An exterior side surface portion 315 extending in the vertical direction is integrally provided at the portion of the exterior extension portion 3112 that is furthest to the exterior side X1. The exterior side surface portion 315 is arranged overlapping in the projection direction on the interior side X2 of the lower end side of the exterior facing surface portion 513 of the upper frame cover member 51. A bent end portion 513a at the lower end of the exterior facing surface portion 513 abuts against the exterior side surface portion 315, and a water-stopping material 513b is provided between the exterior side surface portion 315 and the exterior facing surface portion 513.

[0042] Between the pair of guide rails 314a, 314b of the new upper frame 31, a rail-to-rail cover 3113 made of resin or wood-derived material is attached. The rail-to-rail cover 3113 is disposed across the lower surface 311b of the outdoor frame member 311 and the lower surface side of the connecting member 313 so as to substantially shield the space between the guide rails 314a, 314b of the new upper frame 31. As shown in FIG. 4, the rail-to-rail cover 3113 has a double structure constituted by an upper plate portion 3113a, a lower plate portion 3113b disposed substantially parallel to the lower side of the upper plate portion 3113a, and a plurality of connecting plate portions 3113c connecting the upper plate portion 3113a and the lower plate portion 3113b. The rail-to-rail cover 3113 suppresses the outside air temperature transmitted from the existing upper frame 21 side to the new upper frame 31 from being transmitted to the inner periphery side of the new upper frame 31.

[0043] As shown in Fig. 4, an angle member 319 made of resin or wood-derived material is attached to the end of the indoor side X2 of the indoor side frame member 312 of the newly installed upper frame 31. The angle member 319 is disposed along the underside of the indoor side frame member 312, and is connected to a decorative member 320 that covers the indoor side of the fixed structure on the upper frame side.

[0044] The upper frame side heating foaming material 61 is attached to the indoor side of the upper frame cover member 51 of the attachment 4. The upper frame side heating foaming material 61 is divided into two members, the projection surface foaming material 611 and the exterior surface foaming material 612, each of which is formed in a thin plate shape. The projection surface foaming material 611 is attached to the lower surface of the upper frame projection surface portion 511 of the upper frame cover member 51, and the exterior surface foaming material 612 is attached to the inner surface of the exterior projection surface portion 513 of the upper frame cover member 51. The upper frame side heating foaming material 61 is arranged to form a substantially L-shape in a vertical cross section, and the end of the projection surface foaming material 611 on the exterior side X1 and the upper end of the exterior surface foaming material 612 are adjacent to each other. In this state, when heat such as a fire is applied to the new upper frame, the upper frame side heating foaming material 61 foams so as to close the space between the upper frame cover member 51 and the new upper frame 31. In addition, the upper frame side heating foam material 61 may be arranged on either the front surface foam material 611 or the exterior surface foam material 612, or both may be arranged.

Inside the lower frame body 7121, 7221, a door roller 7123, 7223 is provided and is placed on the guide rails 324a, 324b so as to be rollable.

[0071] 3, the vertical frames 713, 723 are composed of vertical frame bodies 7131, 7231 made of extruded shapes extruded in the length direction from a metal material such as aluminum, and cover members 7132, 7232 made of resin or wood-derived material that cover the indoor side X2 side of the vertical frame bodies 7131, 7231. The vertical frame bodies 7131, 7231 are arranged to sandwich the guide rails 334a, 334b ​​of the newly installed vertical frames in the prospective direction.

[0072] According to this embodiment, the following effects are achieved. The remodeling fixture 1 is configured to include an existing frame 2 provided in an opening 11 of a building skeleton 100, a new frame 3 fixed to the existing frame 2, and an attachment 4 for fixing the new frame 3 to the existing frame 2. The attachment 4 is configured to include an attachment body 40 fixed to the existing frame 2, and a cover member 50 fixed to the attachment body 40 and disposed on the outdoor side X1 of the existing frame 2. The cover member 50 is disposed so as to abut against the existing frame 2 and the new frame 3 from the outdoor side X1 of the existing frame 2, and a heated foaming material 6 is provided on the indoor side of the cover member 50, which foams to seal the gap between the cover member 50 and the new frame 3. By arranging the cover member 50 so that it abuts against the existing frame 2 from the exterior X1 of the existing frame 2, it is easy to adjust the gap caused by the construction error between the new frame 3 or the existing frame 2 and the cover member 50, and the heating foaming material 6 provided on the interior side of the cover member 50 can be easily arranged at an appropriate position. In addition, by covering the existing frame 2 from the outside with the cover member 50, the area covered by the existing frame 2 is increased, excellent fireproof performance, and damage to the existing frame 2 can be reduced. Since the weight of the parts to be handled during construction is lighter than when the attachment 4 is composed of a single member, construction is excellent. Furthermore, since the attachment 4 is divided into two members, the attachment body 40 and the cover member 50, a configuration is provided in which only the cover member 50 is fireproof and the heating foaming material can be attached, and the attachment body 40 can be used for both fireproof and non-fireproof purposes.

The heated foaming material 6 is provided on the indoor side surface of either or both of the outdoor-side visible surface portions 513, 533 and the visible surface portions (upper frame visible surface portion 511, vertical frame visible surface portion 531). As a result, when exposed to heat from the outdoor-side X1, such as a fire, the heated foaming material 6 foams from the outdoor-side X1 to the indoor-side X2, and from above to below or from outside to inside in the visible direction, so that the inner side of the remodeled fitting 1 is well protected.

[0074] According to this embodiment, the existing frame 2 is configured to include an existing upper frame 21 extending in the view direction above the opening 11. The lower end 2121 on the outdoor side X1 of the existing upper frame 21 is arranged to be sandwiched between the attachment body side standing piece 413 provided on the outdoor side X1 of the attachment body 40 and abutting the indoor side X2 of the lower end 2121, and the cover member side standing piece 512 standing from the upper surface of the cover member 50 and arranged on the outdoor side X1 of the lower end 2121. By configuring the attachment 4 to be divided into the upper frame attachment body 41 and the upper frame cover member 51 and connected, the existing frame 2 can be attached so as to be sandwiched from both the indoor and outdoor sides, and fireproof, airtight, and watertight performance can be improved.
