As shown in FIG. 3, the fourth tape 44 is provided over substantially the entire width of the lower attachment 33 and the fourth main body 16A.

[0041] A method for attaching the sash 2 to the support body 1 will be described. Before erecting the sash 2, a second tape 42 is applied between the top frame body 23A and the upper attachment 32 of the sash 2. The top frame body 23A and the upper attachment 32 are fixed with screws 52. A third tape 43 is applied between the bottom frame body 24A and the lower attachment 33. The bottom frame body 24A and the lower attachment 33 are fixed with screws 53. As shown in Figure 2, the sash 2 is erected from the indoor side of the support body 1. A first tape 41 is applied between the third interlock body 15A and the upper attachment 32. The third interlock body 15A and the upper attachment 32 are connected with screws 51. A fourth tape 44 is applied between the lower attachment 33 and the fourth interlock body 16A. The lower attachment 33 and the fourth interlock body 16A are connected with screws 54. A side attachment 31 is attached to the indoor side of the vertical frame 21.

[0042] As shown in Fig. 4, a fire-resistant covering material 61 is provided on the indoor side of the third interlock 15. When viewing the curtain wall 100 from the indoor side, the first tape 41 and the second tape 42 are hidden by the fire-resistant covering material 61 and are not visible. A fire-resistant covering material 62 is provided on the indoor side of the fourth interlock 16. When viewing the curtain wall 100 from the indoor side, the third tape 43 and the fourth tape 44 are hidden by the fire-resistant covering material 62 and are not visible.

[0043] In waterproof structure 101, third gable body 15A made of a metal profile and upper attachment 32 also made of a metal profile are arranged adjacent to each other vertically. A first tape 41 is affixed from surface 152a of first interior-side gable board portion 152 of third gable body 15A to surface 322a of first interior-side upper board portion 322 of upper attachment 32. This blocks outside air from entering the interior side between third gable body 15A and upper attachment 32, thereby improving the waterproofing performance between third gable body 15A and upper attachment 32.

[0044] In the waterproof structure 102, an upper attachment 32 made of a metal extrusion and an upper frame body 23A also made of a metal extrusion are arranged adjacent to each other vertically. A second tape 42 is affixed from a surface 322c of the first indoor-side upper plate portion 322 of the upper attachment 32 to a surface 232a of the indoor-side upper frame plate portion 232 of the upper frame body 23A. This blocks outside air from entering the indoor side between the upper attachment 32 and the upper frame body 23A, thereby improving the waterproofing performance between the upper attachment 32 and the upper frame body 23A.

[0045] In the waterproof structure 103, a lower frame body 24A made of a metal extrusion and a lower attachment 33 also made of a metal extrusion are arranged adjacent to each other vertically. A third tape 43 is affixed from a surface 242a of the first indoor-side lower frame plate portion 242 of the lower frame body 24A to a surface 332a of the first indoor-side lower plate portion 332 of the lower attachment 33. This blocks outside air from entering the indoor side between the lower frame body 24A and the lower attachment 33, thereby improving the waterproofing performance between the lower frame body 24A and the lower attachment 33.

[0046] In the waterproof structure 104, a lower attachment 33 made of a metal extrusion and a fourth transom body 16A also made of a metal extrusion are arranged adjacent to each other vertically. A fourth tape 44 is affixed from a surface 332d of the first indoor-side lower plate portion 332 of the lower attachment 33 to a surface 164a of the second indoor-side transom body 164 of the fourth transom body 16A. This blocks outside air from entering the indoor side between the lower attachment 33 and the fourth transom body 16A, thereby improving the waterproofing performance between the lower attachment 33 and the fourth transom body 16A.

[0047] Since the first tape 41, the second tape 42, the third tape 43 and the fourth tape 44 are made of aluminum, the ability to block outside air can be improved and waterproofing can be more reliably achieved.

[0048] The shapes and combinations of the components shown in the above-described embodiments are merely examples, and various modifications can be made based on design requirements, etc., within the scope of the present disclosure.

[0049] For example, in the above embodiment, the third transom body 15A, the upper attachment 32, the upper frame body 23A, the lower frame body 24A, the lower attachment 33, and the fourth transom body 16A, all made of metal extrusions, have been described as examples of the waterproof structure of the metal extrusions, but the present invention is not limited to this. A mullion made of metal extrusions may also be used.

[0050] In the above embodiment, glass is housed within the support body 1 and the sash 2, but the type of glass can be set as appropriate. Panel material may be housed instead of glass.

[0051] In the above-described embodiment, the first tape 41, the second tape 42, the third tape 43, and the fourth tape 44 are made of a metal such as aluminum, which has a high airtightness, but this is not limited thereto. The first tape 41, the second tape 42, the third tape 43, and the fourth tape 44 may also be waterproof and airtight tapes that are highly waterproof and airtight. Examples of waterproof and airtight tapes that can be used include Airtight Waterproof Tape No. 740 (manufactured by Sekisui Chemical Co., Ltd.) and Smart Seal Tape (manufactured by 3M Japan Ltd.). Even waterproof and airtight tapes can improve the airtightness and more reliably stop water. [Explanation of symbols]
