The second adhesive 42 is shown in Figure 3. 【0017】 The first adhesive 41 is provided along the direction in which each of the outer peripheral ends 241, 242, 243 of the body fixing plate portion 22 extends at the corner portions 61, 62, 63 formed by each of the outer peripheral ends and the lower surface 311 of the lower flange 31 of the body 3. The first adhesive 41 is adhered to both each of the outer peripheral ends 241, 242, 243 of the body fixing plate portion 22 and the lower surface 311 of the lower flange 31. The corner portions 61, 62, 63 are each a right angle. The corner portion 61 formed by the first outer peripheral end 241 of the body fixing plate portion 22 and the lower surface 311 of the lower flange 31 is denoted as the first corner portion 61. The corner portion formed by the second outer peripheral end 242 of the body fixing plate portion 22 and the lower surface 311 of the lower flange 31 is denoted as the second corner portion 62. The corner portion formed by the third outer peripheral end 243 of the body fixing plate portion 22 and the lower surface 311 of the lower flange 31 is denoted as the third corner portion 63. 【0018】 The second adhesive 42 is provided along the direction in which the outdoor-side end surface 312 of the lower flange 31 extends at the fourth corner portion 64 formed by the outdoor-side end surface 312 of the lower flange 31 and the upper surface 221 of the body fixing plate portion 22. The fourth corner portion 64 is a right angle. The outdoor-side end surface 312 of the lower flange 31 corresponds to the "outer peripheral end of the body" in the claims. The second adhesive 42 is adhered to both the outdoor-side end surface 312 of the lower flange 31 and the upper surface 221 of the body fixing plate portion 22. 【0019】 The first adhesive 41 and the second adhesive 42 are, for example, two-component adhesives that cure at room temperature. An angle member 43 is provided on the surfaces of the first adhesive 41 and the second adhesive 42. The angle member 43 is a piece-shaped member that extends linearly and has an L-shaped cross-section.

One piece of the L-shaped cross-section of the angle member 43 is denoted as the first piece 431, and the other piece is denoted as the second piece 432. The first piece 431 and the second piece 432 have the same plate surface shape and plate thickness. The first piece 431 and the second piece 432 form a 90° angle. The angle member 43 is made of, for example, steel, aluminum alloy, stainless steel, etc. The surfaces of the angle member 43 on the side opposite to the side where the first piece 431 and the second piece 432 are connected, and on the side opposite to the side where the second piece 432 and the first piece 431 are connected are denoted as the outer surfaces 433. 【0020】 The posture of the angle member 43 provided on the surface of the first adhesive 41 is such that the plate surface of one of the first piece 431 and the second piece 432 is a vertical surface facing the indoor-outdoor direction, and the other protrudes indoors from the upper edge of the one. In this embodiment, the first piece 431 is the one piece, and the second piece 432 is the other piece. The first piece 431 faces the first outer peripheral end 241 of the housing fixing plate portion 22 in the indoor-outdoor direction via the first adhesive 41. The second piece 432 faces the lower surface 311 of the lower flange 31 from below via the first adhesive 41. The corner formed by the first piece 431 and the second piece 432 of the angle member 43 presses the first adhesive 41 against the first outer peripheral end 241 and the lower surface 311 of the lower flange 31. The angle member 43 covers the entire surface of the first adhesive 41 provided at the first corner 61 over the entire width direction. 【0021】 The angle members 43 provided at the second corner 62 and the third corner 63 are positioned such that the plate surface of one piece of the first piece 431 and the second piece 432 faces the width direction as a vertical plane, and the other piece protrudes in the width direction from the upper edge of one of the pieces. In this embodiment, the first piece 431 is one piece, and the second piece 432 is the other piece. The first piece 431 faces the second outer peripheral end 242 and the third outer peripheral end 243 of the structural fixing plate portion 22 via the first adhesive 41. The second piece 432 faces the upper surface 221 of the structural fixing plate portion 22 via the first adhesive 41. The corners formed by the first piece 431 and the second piece 432 of the angle member 43 press the first adhesive 41 against the second outer peripheral end 242, the third outer peripheral end 243, and the upper surface 221 of the structural fixing plate portion 22. The angle material 43 covers the entire surface of the first adhesive 41 over its entire width. It also covers the surfaces of the first adhesive 41 provided at the second corner 62 and the third corner 63 over its entire width in both indoor and outdoor directions. 【0022】 When the angle material 43 is placed on its surface, the first adhesive 41 is pressed against the outer surface 433 of the angle material 43. The cross-sectional shape of the first adhesive 41 is approximately L-shaped. The first adhesive 41 is bonded to both the fastener 2 and the structure 3 even when the angle material 43 is placed on its surface. 【0023】 As shown in Figure 3, the angle material 43 provided at the fourth corner 64 is positioned such that the plate surface of one of the first piece 431 and the second piece 432 faces the indoor / outdoor direction, with one piece protruding to the outdoors from the lower edge of the other piece. In this embodiment, the first piece 431 is one piece, and the second piece 432 is the other piece. The first piece 431 faces the outdoor end face 312 of the lower flange 31 via the second adhesive 42. The second piece 432 faces the upper surface 221 of the frame fixing plate portion 22 of the fastener 2 via the second adhesive 42. The angle material 43 covers the entire surface of the second adhesive 42 in the width direction. 【0024】 The method for fixing the curtain wall will be explained below. The structural fixing plate portion 22 of the fastener 2 attached to the curtain wall 11 is placed on top of the lower flange 31 of the structural frame 3, overlapping from below. The fastener 2 and the structural frame 3 are joined together with bolts 5. 【0025】 First adhesive 41 is applied to the corners 61, 62, 63 formed by the outer peripheral ends 241, 242, 243 of the frame fixing plate portion 22 of fastener 2 and the lower surface 311 of the lower flange 31, along the direction in which the outer peripheral ends 241, 242, 243 of the frame fixing plate portion 22 extend. Angle material 43 is provided on the surface of the first adhesive 41. Second adhesive 42 is applied to the fourth corner 64 formed by the outer end surface 312 of the lower flange 31 and the upper surface 221 of the frame fixing plate portion 22, along the direction in which the outer end surface 312 of the lower flange 31 extends. Angle material 43 is provided on the surface of the second adhesive 42. The first adhesive 41 and the second adhesive 42 are cured to fix the frame fixing plate portion 22 and the lower flange 31. Fastener 2 is fixed to the frame 3, and the curtain wall 11 is fixed to the frame 3 of the building. 【0026】 The curtain wall fixing structure 1 and the method for fixing the curtain wall involve fixing fasteners 2 to the building structure 3 with adhesive 4, and then attaching the curtain wall 11 to the fasteners 2. Unlike conventional methods, the curtain wall fixing structure 1 does not require welding the fasteners 2 to the building structure 3. Therefore, the curtain wall fixing structure 1 allows for easy and safe joining of the fasteners 2 to the building structure 3. By not applying adhesive 4 to the upper surface of the fasteners 2, the position of the fasteners 2 relative to the building structure 3 can be easily adjusted. 【0027】 In the curtain wall fixing structure 1, the fastener 2 is bonded to the frame 3 with adhesive 4 and also bolted. This allows for a stronger fixation between the fastener 2 and the frame 3. By bolting the fastener 2 to the frame 3 before bonding the fastener 2 to the frame 3 with the first adhesive 41, the fastener 2 can be easily bonded to the frame 3 with adhesive 4 without shifting position relative to the frame 3. 【0028】 In the curtain wall fixing structure 1, angle members 43 are provided on the surfaces of the first adhesive 41 and the second adhesive 42. The first adhesive 41 adheres uniformly and widely to the outer peripheral ends 241, 242, 243 of the structural fixing plate portion 22 and the lower surface 311 of the lower flange 31 of the structural body 3 by being pressed against the outer surface 433 of the angle member 43. The second adhesive 42 adheres uniformly and widely to the upper surface 221 of the structural fixing plate portion 22 and the end surface 312 of the lower flange 31 by being pressed against the outer surface 433 of the angle member 43. 【0029】 In the curtain wall fixing structure 1, the first adhesive 41 and the second adhesive 42 are two-component adhesives that cure at room temperature. The fastener 2 can be bonded to the structure 3 without using heat, and no equipment or power supply is required for bonding the first adhesive 41 and the second adhesive 42. 【0030】 Other embodiments will be described. The same reference numerals are used for components and parts that are identical or similar to those in the first embodiment, and their descriptions will be omitted. Configurations that differ from the first embodiment will be described. 【0031】 As shown in Figures 5 and 6, in the curtain wall fixing structure 1B according to the second embodiment, the frame 12 is made of wood. Figure 5 is a vertical cross-sectional view corresponding to the cross-section along line CC in Figure 6. The frame-side bracket 7 attached to the frame 12 is a plate material with an L-shaped cross-section. The frame-side bracket 7 has a first plate portion 71 attached along the lower end surface of the frame 12 and a second plate portion 72 attached along the lower end of the outdoor side surface of the frame 12. The frame-side bracket 7 is included in the "bracket" of the claims. 【0032】 The first plate portion 71 is flat. The first plate portion 71 is one of the two pieces that make up the L-shape of the frame-side bracket 7. The first plate portion 71 is attached to the lower surface of the frame 12 with fasteners such as screws, with the plate surface facing horizontally. The second plate portion 72 is the other of the two pieces that make up the L-shape of the frame-side bracket 7. The second plate portion 72 protrudes upward from the outdoor edge of the first plate portion 71, with the plate surface facing vertically in the direction of indoors or outdoors. The frame fixing plate portion 22 of the fastener 2 is placed on top of the first plate portion 71. The first plate portion 71 protrudes more towards the indoor side than the frame fixing plate portion 22. 【0033】 The first adhesive 41 is applied to the corners 61, 62, and 63 formed by the outer peripheral ends 241, 242, and 243 of the structural frame fixing plate portion 22 and the lower surface 711 of the first plate portion 71 of the structural frame bracket 7, along the direction in which each outer peripheral end 241, 242, and 243 extends. The second adhesive 42 is applied to the corner 64 formed by the outdoor-facing surface 721 of the second plate portion 72 of the structural frame bracket 7 and the upper surface 221 of the structural frame fixing plate portion 22, along the width direction in which the structural frame bracket 7 extends. The outdoor-facing surface 721 of the second plate portion 72 of the structural frame bracket 7 corresponds to the "outer peripheral end of the bracket" in the claims. Angle material 43 is provided on the surfaces of the first adhesive 41 and the second adhesive 42. 【0034】 In the curtain wall fixing structure 1B according to the second embodiment, when fixing the curtain wall 11 to the wooden frame 12, even if the frame-side bracket 7 is attached to the frame 12, the fastener 2 can be fixed to the frame-side bracket 7 with adhesive 4, and the curtain wall 11 can be attached to the fastener 2. For this reason, the curtain wall fixing structure 1B according to the second embodiment provides the same effect as the curtain wall fixing structure 1 according to the first embodiment. 【0035】 As shown in Figure 7, the curtain wall fixing structure 1C according to the third embodiment is provided with a first notch 25, which is a corner cut out on the upper side of the first outer peripheral end 241 of the structural fixing plate portion 22C of the fastener 2C. The first notch 25 is cut out from the first outer peripheral end 241 of the structural fixing plate portion 22C toward the outside. The first notch 25 is provided with a notched surface 251 that is inclined upward toward the outside from the first outer peripheral end 241 of the structural fixing plate portion 22C toward the outside. The curtain wall fixing structure 1C does not have an angle member 43. 【0036】 In the curtain wall fixing structure 1C according to the third embodiment, the first adhesive 41 provided at the first corner 61 formed by the first outer peripheral end 241 of the structural fixing plate portion 22C and the lower surface 311 of the lower flange 31 of the structural body 3 enters the first notch portion 25 and adheres to the notched surface 251 of the inclined surface. This allows the surface area to which the first adhesive 41 adheres to the structural fixing plate portion 22C at the first corner portion 61 to be increased. The fastener 2C and the structural body 3 can be firmly bonded. Alternatively, the fastener 2 fixed to the structural body bracket 7 in the second embodiment may be provided with the first notch portion 25 provided in the fastener 2C of the third embodiment, and the fastener 2 and the structural body bracket 7 may be bonded by allowing the first adhesive 41 to enter the first notch portion 25. 【0037】 As shown in Figure 8, the curtain wall fixing structure 1D according to the fourth embodiment has a groove-shaped second notch 222 that opens upward on the upper surface 221 of the frame fixing plate portion 22D of the fastener 2D. The second notch 222 extends across the entire width direction of the frame fixing plate portion 22D. Multiple second notches 222 are provided at intervals in the indoor and outdoor directions. The second notches 222 are filled with a third adhesive 44 similar to the first adhesive 41 and the second adhesive 42. The curtain wall fixing structure 1D does not have an angle member 43. 【0038】 In the curtain wall fixing structure 1D according to the fourth embodiment, the structural fixing plate portion 22D of the fastener 2D and the lower surface 311 of the lower flange 31 of the structural body 3 can be bonded by the third adhesive 44 filled in the groove-shaped second notch portion 222 that opens upward on the upper surface 221 of the structural fixing plate portion 22D of the fastener 2D. The fastener 2D and the structural body 3 can be firmly bonded. Alternatively, the fastener 2 fixed to the structural body side bracket 7 of the second embodiment may be provided with the second notch portion 222 provided in the fastener 2D of the fourth embodiment, and the fastener 2 and the structural body side bracket 7 may be bonded by filling the second notch portion 222 with the third adhesive 44. 【0039】 This disclosure is not limited to the embodiments described above and can be modified as appropriate. For example, in the first embodiment, the first adhesive 41 may be provided at any of the corners 61, 62, 63 formed by the outer peripheral ends 241, 242, 243 of the frame fixing plate portion 22 of the fastener 2 and the lower surface 311 of the lower flange 31 of the frame 3. In the second embodiment, the first adhesive 41 may be provided at any of the corners 61, 62, 63 formed by the outer peripheral ends 241, 242, 243 of the frame fixing plate portion 22 of the fastener 2 and the lower surface 711 of the first plate portion 71 of the frame-side bracket 7. In both the first and second embodiments, it is preferable that the first adhesive 41 is provided at least at the first corner 61. 【0040】 The fastener 2 and the frame 3 do not necessarily have to be bolted together. If the fastener 2 and the frame 3 are bolted together, the position and number of bolts may be set as appropriate. In the second embodiment, the fastener 2 and the frame-side bracket 7 may be bolted together. 【0041】 The fastener 2 overlaps and contacts the lower surface 311 of the structural frame 3, but it may also overlap and contact a surface other than the lower surface 311, such as the upper surface of the structural frame 3. For example, the fastener 2 may overlap and contact the upper surface of the upper flange of the structural frame 3. In the second embodiment, the fastener 2 may overlap and contact a structural frame-side bracket 7 provided on a surface other than the lower surface 311, such as the upper surface of the structural frame 3. 【0042】 In the first and second embodiments, angle members 43 are not required to be provided on the surfaces of the first adhesive 41 and the second adhesive 42. In the third and fourth embodiments, angle members 43 are provided on the surfaces of the first adhesive 41 and the second adhesive 42.
