Description

Technical Field

[0001] The present invention relates to a curtain wall to which a mounting unit is attached to a frame body.

Background Art

[0002] In a curtain wall having a frame body, the frame body is attached to a building, and the curtain wall is installed on the building. Further, the curtain wall is located at a portion of the outer wall of the building and is disposed between the inside and outside of the building. As such a curtain wall having a frame body, conventionally, a gallery unit including a mounting frame as the frame body and a blade unit as a mounting unit attached to the mounting frame is known (see Patent Document 1).

[0003] In the conventional gallery unit described in Patent Document 1, the mounting frame has an upper frame, a lower frame, and left and right vertical frames, and the blade unit has a blade unit frame and a plurality of slats. Further, the blade unit frame has an upper frame member, a lower frame member, left and right vertical frame members, and a middle bone. The blade unit frame and the blade unit are attached to the mounting frame by fixing the middle bone to the upper frame and connecting it to the lower frame, and fixing the vertical frame members to the vertical frames. However, in the conventional gallery unit, on the outer wall of the building, the blade unit frame and the blade unit cannot be easily removed from the mounting frame. Therefore, for example, when it is necessary to transport objects inside and outside the building through the opening of the mounting frame from which the blade unit has been removed, it is difficult to respond to the request to remove the blade unit from the mounting frame.

The curtain wall in this embodiment is a wall structure used for the exterior wall of a building. The curtain wall is an exterior wall of a building, installed between the interior and exterior of the building, and forms the exterior wall of the building.

[0010] FIG. 1 is a front view showing the outer wall 11 of the building 10 including the curtain wall 1 of the present embodiment, showing the curtain wall 1 and the outer wall 11 of the building 10 as viewed from the outdoor side. FIG. 2 is a cross-sectional view showing the outer wall 11 of the building 10 including the curtain wall 1 of the present embodiment, showing the curtain wall 1 and the outer wall 11 of the building 10 cut along a plane including the left-right direction S and the indoor-outdoor direction T. FIG. 3 is a longitudinal sectional view showing the outer wall 11 of the building 10 including the curtain wall 1 of the present embodiment, showing the curtain wall 1 and the outer wall 11 of the building 10 cut along a plane including the up-down direction R and the indoor-outdoor direction T.

[0011] When the curtain wall 1 installed in the building 10 is viewed from the front, the up-down direction is the up-down direction R, and the left-right direction is the left-right direction S. In FIG. 1, the up-down direction R is the vertical direction, and the left-right direction S is the horizontal direction. The indoor-outdoor direction T is the indoor-outdoor direction (indoor-outdoor direction) in the curtain wall 1 installed in the building 10. Also, when the curtain wall 1 installed in the building 10 is viewed from the front, the indoor-outdoor direction T is the front-back direction (depth direction) and the thickness direction of the curtain wall 1, and in FIG. 2, it is the horizontal direction orthogonal to the left-right direction S. Thus, the directions related to the curtain wall 1 are specified in the state of being installed in the building 10. Also, the indoor side and the outdoor side with respect to the curtain wall 1 are the indoor side and the outdoor side in the state of being installed in the building 10.

[0012] As shown in the drawing, the building 10 includes a plurality of curtain walls 1, 2 including the curtain wall 1 of the present embodiment. The plurality of curtain walls 1, 2 are wall bodies each constituting a part of the outer wall 11 of the building 10 and are installed side by side on the building 10. Also, the plurality of curtain walls 1, 2 are installed side by side in the up-down direction R and the left-right direction S and are adjacent to each other. The curtain walls 1, 2 are arranged on the outdoor side of the frame 12 of the building 10 and are attached to the frame 12 of the building 10.

[0013] Of the multiple curtain walls 1 and 2, the curtain walls 2 other than the curtain wall 1 of this embodiment (other curtain walls 2) are modular curtain walls (curtain wall units) that are installed in the building 10 as a single unit, and are pre-assembled before installation in the building 10. In contrast, the curtain wall 1 of this embodiment is not installed in the building 10 as a single unit. The other curtain walls 2 are arranged around the curtain wall 1 of this embodiment, surrounding it. The curtain wall 1 of this embodiment is arranged between the other curtain walls 2 in both the vertical direction R and the horizontal direction S, and is adjacent to the other curtain walls 2.

[0014] Figure 4 is a front view showing the curtain wall 1 of this embodiment, schematically illustrating the curtain wall 1 extracted from the multiple curtain walls 1 and 2 shown in Figure 1. Figure 5 is an exploded front view showing the curtain wall 1 of this embodiment, illustrating the general configuration of the curtain wall 1.

[0015] As shown in the figure, the curtain wall 1 comprises a frame 3 installed in the building 10 and one or more mounting units 4A, 4B, and 4C positioned inside the opening 3A of the frame 3 and attached to the frame 3. The frame 3 is an opening frame that forms the opening 3A and is positioned on the outdoor side of the building structure 12 of the building 10 and attached to the building structure 12 of the building 10. The frame 3 surrounds the mounting units 4A, 4B, and 4C of the curtain wall 1 and holds the mounting units 4A, 4B, and 4C. The mounting units 4A, 4B, and 4C are removable units from the frame 3 and are pre-assembled before installation in the building 10.

[0016] Here, the curtain wall 1 comprises a plurality (three) of mounting units 4A, 4B, and 4C (first mounting unit 4A, second mounting unit 4B, and third mounting unit 4C) arranged side by side in the opening 3A of the frame 3. The plurality of mounting units 4A, 4B, and 4C are arranged side by side in the left-right direction S, and are adjacent to each other in the left-right direction S. In the left-right direction S, the first mounting unit 4A and the third mounting unit 4C are located on one side and the other side of the second mounting unit 4B, and the second mounting unit 4B is located between the first mounting unit 4A and the third mounting unit 4C.

[0017] On the exterior wall 11 of the building 10, the mounting units 4A, 4B, and 4C are detachably attached to the frame 3 and can be removed from the frame 3 toward the outside. In addition, multiple mounting units 4A, 4B, and 4C are individually placed in the opening 3A of the frame 3 and attached to the frame 3, and can be individually removed from the frame 3. The mounting units 4A, 4B, and 4C are placed only inside the opening 3A of the frame 3, or both inside the opening 3A of the frame 3 and toward the outside.

[0018] Frame 3 has multiple frames 5-8 (upper frame 5, lower frame 6, and a pair of vertical frames 7 and 8) that are combined with each other, and frames 5-8 form a rectangular opening 3A. Frames 5-8 of frame 3 are constituent materials (frame constituent materials) that make up frame 3, and each is made of a metal (for example, made of aluminum alloy) profile formed by extrusion molding. The longitudinal direction of frames 5-8 is the direction in which frames 5-8 extend (extension direction). The longitudinal direction of the upper frame 5 and lower frame 6 is the left-right direction S, and the longitudinal direction of the vertical frames 7 and 8 is the up-down direction R.

[0019] The upper frame 5 and lower frame 6 are upper and lower horizontal frames (upper horizontal frame, lower horizontal frame) located at the top and bottom of the frame body 3, and extend in the horizontal direction (left-right direction S). The pair of vertical frames 7 and 8 (first vertical frame 7, second vertical frame 8) are side frames located on the left and right sides of the frame body 3, and extend in the vertical direction (up-down direction R). The upper frame 5 is provided between the upper ends of the left and right vertical frames 7 and 8 and is attached to the building structure 12 of the building 10 at multiple locations in the left-right direction S. The lower frame 6 is provided between the lower ends of the left and right vertical frames 7 and 8 and is attached to the frame body (upper frame) of another curtain wall 2 located below the curtain wall 1 at multiple locations in the left-right direction S. The mounting units 4A, 4B, and 4C are surrounded by frames 5 to 8 of the frame body 3 and are installed in the opening 3A of the frame body 3.

[0020] The frame 3 is formed as a divided structure divided into multiple parts, and has at least one pair of divided frame sections 3B, 3C (first divided frame section 3B, second divided frame section 3C). Here, the frame 3 is divided in the left-right direction S, and is divided into multiple parts including the left and right divided frame sections 3B, 3C. In the outer wall 11 of the building 10, multiple parts of the frame 3 are combined to form the frame 3. The upper frame 5 is a divided upper frame divided into multiple parts in the longitudinal direction of the upper frame 5, and has multiple (3) upper members 5A, 5B, 5C (first upper member 5A, second upper member 5B, third upper member 5C). The lower frame 6 is a divided lower frame divided into multiple parts in the longitudinal direction of the lower frame 6, and has multiple (3) lower members 6A, 6B, 6C (first lower member 6A, second lower member 6B, third lower member 6C).

[0021] The first upper member 5A and the second upper member 5B are upper members (end upper members) located at the left and right ends of the upper frame 5, and are spaced apart in the longitudinal direction of the upper frame 5. The third upper member 5C is an upper member (intermediate upper member) located in the middle of the longitudinal direction of the upper frame 5, and is located between the first upper member 5A and the second upper member 5B. Multiple upper members 5A, 5B, and 5C are arranged in a line along the longitudinal direction of the upper frame 5 at the top of the frame body 3, and constitute the upper frame 5. The first lower member 6A and the second lower member 6B are lower members (end lower members) located at the left and right ends of the lower frame 6, and are spaced apart in the longitudinal direction of the lower frame 6. The third lower member 6C is a lower member (intermediate lower member) located in the middle of the longitudinal direction of the lower frame 6, and is located between the first lower member 6A and the second lower member 6B. Multiple lower members 6A, 6B, and 6C are arranged in a line along the longitudinal direction of the lower frame 6 at the lower part of the frame body 3, thereby constituting the lower frame 6.

[0022] The first divided frame section 3B has a first vertical frame 7, a first upper member 5A, and a first lower member 6A, and the second divided frame section 3C has a second vertical frame 8, a second upper member 5B, and a second lower member 6B. Before installing the frame body 3 to the building 10, the ends of the first vertical frame 7, the first upper member 5A, and the first lower member 6A are connected in advance to form the first divided frame section 3B. Also, the ends of the second vertical frame 8, the second upper member 5B, and the second lower member 6B are connected to form the second divided frame section 3C.

[0023] The first divided frame section 3B and the second divided frame section 3C are each attached to the building frame 12 of the building 10 and installed in the building 10. The third upper member 5C and the third lower member 6C are each positioned between the first divided frame section 3B and the second divided frame section 3C and installed in the building 10. At this time, the upper members 5A, 5B, and 5C are attached to the building frame 12 of the building 10, and the lower members 6A, 6B, and 6C are attached to the frames of the other curtain wall 2. With the third upper member 5C positioned between the first upper member 5A and the second upper member 5B, a sealing material 5D is provided between the ends of the upper members 5A, 5B, and 5C, connecting the upper members 5A, 5B, and 5C to each other. With the third lower member 6C positioned between the first lower member 6A and the second lower member 6B, a sealing material 6D is provided between the ends of the lower members 6A, 6B, and 6C, thereby connecting the lower members 6A, 6B, and 6C to each other.

[0024] The sealant 5D seals the gaps between the ends of the upper members 5A, 5B, and 5C, and the sealant 6D seals the gaps between the ends of the lower members 6A, 6B, and 6C. The third upper member 5C and the third lower member 6C are connected to the first divided frame section 3B and the second divided frame section 3C by sealants 5D and 6D, respectively. Dividing the frame 3 into multiple parts (divided frame sections 3B, 3C, third upper member 5C, and third lower member 6C) makes it easier to transport the frame 3. Furthermore, even when the frame 3 is large, it is easy to transport the frame 3, and it is also easy to install the frame 3 in the building 10.

[0025] Figure 6 is a cross-sectional view showing the exterior wall 11 of the building 10 including the frame 3 of the curtain wall 1 of this embodiment, and shows the curtain wall 1 with the mounting units 4A, 4B, and 4C removed from the frame 3 compared to the curtain wall 1 shown in Figure 2. Figure 7 is a vertical cross-sectional view showing the exterior wall 11 of the building 10 including the frame 3 of the curtain wall 1 of this embodiment, and shows the curtain wall 1 with the mounting units 4A, 4B, and 4C removed from the frame 3 compared to the curtain wall 1 shown in Figure 3.

[0026] As shown in the diagram, with the curtain wall 1 installed in the building 10, the opening 3A of the frame 3 is opened by removing the mounting units 4A, 4B, and 4C from the frame 3. This opens the interior of the building 10 to the outside through the opening 3A of the frame 3, allowing for the transport of objects between the inside and outside of the building 10. For example, if the interior side of the curtain wall 1 of the building 10 is an electrical room or a machine room, transported objects (equipment, machinery, indoor facilities, etc.) can be moved from the inside of the building 10 to the outside, or from the outside of the building 10 to the inside, through the opening 3A of the frame 3.

[0027] Figure 8 is a vertical cross-sectional view showing the mounting unit of the curtain wall 1 in this embodiment, and Figure 9 is a horizontal cross-sectional view showing the mounting unit of the curtain wall 1 in this embodiment. Figures 8 and 9 show the second mounting unit 4B, one of the three mounting units 4A, 4B, and 4C. The first mounting unit 4A and the third mounting unit 4C are configured similarly to the second mounting unit 4B, and their description is omitted. The same names and reference numerals as those used for the second mounting unit 4B are used for the configurations of the first mounting unit 4A and the third mounting unit 4C.

[0028] As shown in the figure, the second mounting unit 4B of the curtain wall 1 has a unit frame 20 that is removable from the frame 3, and one or more mounting bodies 30, 40 that are attached to the opening 21 of the unit frame 20. The unit frame 20 is an opening frame that forms the opening 21 and is surrounded by the frame 3. The mounting bodies 30, 40 are attached to the unit frame 20, positioned on the inside, outside, or both sides of the opening 21 of the unit frame 20.

[0029] The unit frame 20 is positioned in the opening 3A of the frame body 3 and is detachably fixed to the frame body 3. The fixing of the unit frame 20 to the frame body 3 allows the second mounting unit 4B to be detachably attached to the frame body 3. The mounting bodies 30 and 40 are held by the unit frame 20 and move together with the unit frame 20. When the fixing of the unit frame 20 to the frame body 3 is released, the unit frame 20 and the second mounting unit 4B, together with the mounting bodies 30 and 40, move outwards from the opening 3A of the frame body 3 and are removed from the frame body 3 toward the outdoors.

[0030] The unit frame 20 has multiple frame members 22-25 (upper frame member 22, lower frame member 23, and a pair of vertical frame members 24, 25) that are combined with each other, and the frame members 22-25 form a rectangular opening 21. The frame members 22-25 of the unit frame 20 are constituent materials (unit frame constituent materials) of the unit frame 20, and each is made of a metal (for example, made of aluminum alloy) profile formed by extrusion molding. The longitudinal direction of the frame members 22-25 is the direction in which the frame members 22-25 extend (extension direction). The longitudinal direction of the upper frame member 22 and the lower frame member 23 is the left-right direction S, and the longitudinal direction of the vertical frame members 24, 25 is the up-down direction R.

[0031] The upper frame member 22 and the lower frame member 23 are upper and lower horizontal frame members (upper horizontal frame member, lower horizontal frame member) located at the top and bottom of the unit frame 20, and extend in the horizontal direction. The pair of vertical frame members 24 and 25 (first vertical frame member 24, second vertical frame member 25) are side frame members located on the left and right sides of the unit frame 20, and extend in the vertical direction. The ends of the upper frame member 22, the lower frame member 23, and the left and right vertical frame members 24 and 25 are connected to each other, forming the frame members 22 to 25.

[0032] The unit frame 20 has connecting members 26 and 27 (upper connecting member 26, lower connecting member 27) that connect the unit frame 20 to the frame body 3. The connecting members 26 and 27 are located on the outer circumference of the unit frame 20 and protrude from the unit frame 20. The upper connecting member 26 is located above the upper frame member 22, attached to the upper frame member 22, and protrudes upward from the upper frame member 22. The lower connecting member 27 is located below the lower frame member 23, attached to the lower frame member 23, and protrudes downward from the lower frame member 23. The upper connecting member 26 is provided at multiple locations along the longitudinal direction of the upper frame member 22, and the lower connecting member 27 is provided at multiple locations along the longitudinal direction of the lower frame member 23.

[0033] The mounting components 30 and 40 are, for example, louvers, panels, opening / closing mechanisms, decorative elements, and decorative materials, and are positioned facing the opening 21 of the unit frame 20 and mounted on the unit frame 20. Here, the second mounting unit 4B has a plurality (two) of mounting components 30 and 40 (first mounting component 30, second mounting component 40) spaced apart in the indoor / outdoor direction T. The first mounting component 30 is a louver and has a plurality of slats 31 arranged in parallel. The second mounting component 40 is a panel and closes the opening 21 of the unit frame 20. The first mounting component 30 is the outdoor mounting component of the second mounting unit 4B and is located on the outdoor side of the second mounting component 40. The second mounting component 40 is the indoor mounting component of the second mounting unit 4B and is located on the indoor side of the first mounting component 30.

[0034] Each of the multiple slats 31 is a slat extending in the vertical direction R, and is spaced apart from each other in the left-right direction S. The multiple slats 31 and the first mounting body 30 are located between the left and right vertical frame members 24 and 25, and are located on the outdoor side of the upper frame member 22 and the lower frame member 23. Brackets 32 and 33 are fixed to the upper frame member 22 and the lower frame member 23, respectively. The multiple slats 31 are fixed to the upper and lower brackets 32 and 33, and are attached to the unit frame 20 (upper frame member 22, lower frame member 23) by the upper and lower brackets 32 and 33. The multiple slats 31 and the first mounting body 30 are attached to the unit frame 20 via the upper and lower brackets 32 and 33.

[0035] The other curtain wall 2 adjacent to curtain wall 1 is a ventilated curtain wall that allows ventilation between the interior and exterior of curtain wall 2, and is equipped with louvers having multiple fins for ventilation. In contrast, curtain wall 1 is a non-ventilated curtain wall that does not allow ventilation between the interior and exterior of curtain wall 1, and is equipped with a first mounting unit 30, which is a louver, in order to match the design of the other curtain wall 2. Curtain wall 1 is also equipped with a second mounting unit 40, which is a panel, to block ventilation on the interior side of the first mounting unit 30.

[0036] Figure 10 is a vertical cross-sectional view showing the upper part of the curtain wall 1 of this embodiment, showing the upper frame 5 of the frame 3 and the upper frame material 22 side of the unit frame 20 in the mounting units 4A, 4B, and 4C. Figure 11 is a vertical cross-sectional view showing the lower part of the curtain wall 1 of this embodiment, showing the lower frame 6 of the frame 3 and the lower frame material 23 side of the unit frame 20 in the mounting units 4A, 4B, and 4C. Also, Figure 10 shows another curtain wall 2 adjacent to the upper side of curtain wall 1, and Figure 11 shows another curtain wall 2 adjacent to the lower side of curtain wall 1.

[0037] As shown in the figure, the frame 3 has connecting members 3D and 3E (upper connecting member 3D, lower connecting member 3E) to which the unit frame 20 is connected. The connecting members 3D and 3E are located on the inner circumference side (opening 3A side) of the frame 3 and protrude from the frame 3. The upper connecting member 3D is located below the upper frame 5, attached to the upper frame 5, and protrudes downward from the upper frame 5.

The cover 70 and the sealant 71 are located on the indoor side of the upper connecting member 26, the upper connected member 3D, and the upper fastening component 50, and are provided between the upper frame 5 and the upper frame member 22. The upper connecting member 26, the upper connected member 3D, and the upper fastening component 50 are located on the outdoor side of the cover 70 and the sealant 71 within the gap 60, and are shielded on the indoor side by the cover 70 and the sealant 71.

[0042] The gap 61 between the lower frame 6 of the frame body 3 and the lower frame material 23 of the unit frame 20 is sealed on the indoor side by a sealant 72. The sealant 72 is located on the indoor side of the lower connecting material 27, the lower covered connecting material 3E, and the lower fastening component 51, and is provided between the lower frame 6 and the lower frame material 23. The lower connecting material 27, the lower covered connecting material 3E, and the lower fastening component 51 are located on the outdoor side of the sealant 72 within the gap 61 and are shielded on the indoor side by the sealant 72.

[0043] Figures 12 to 14 are cross-sectional views showing the curtain wall 1 of this embodiment divided in the left-right direction S. Figure 12 shows the first vertical frame 7 of the frame 3, the portion of the unit frame 20 on the first vertical frame member 24 side in the first mounting unit 4A, and another curtain wall 2 adjacent to the side of the curtain wall 1. Figure 13 shows the portion of the unit frame 20 on the second vertical frame member 25 side in the first mounting unit 4A, the second mounting unit 4B, and the portion of the unit frame 20 on the first vertical frame member 24 side in the third mounting unit 4C. Figure 14 shows the second vertical frame 8 of the frame 3, the portion of the unit frame 20 on the second vertical frame member 25 side in the third mounting unit 4C, and another curtain wall 2 adjacent to the side of the curtain wall 1.

[0044] As shown in the figures, the unit frame 20 of the first mounting unit 4A (see Figure 12) and the unit frame 20 of the third mounting unit 4C (see Figure 14) each have connecting members 28 (vertical connecting members 28) that connect the unit frame 20 to the frame body 3. The vertical connecting members 28 are located on the outer circumference of the unit frame 20 and protrude from the unit frame 20. In the first mounting unit 4A, the vertical connecting members 28 are located to the side of the first vertical frame member 24, attached to the first vertical frame member 24, and protrude laterally from the first vertical frame member 24. In the third mounting unit 4C, the vertical connecting members 28 are located to the side of the second vertical frame member 25, attached to the second vertical frame member 25, and protrude laterally from the second vertical frame member 25. The vertical connecting members 28 are provided at multiple locations along the longitudinal direction of the vertical frame members 24 and 25.

[0045] The frame 3 has connecting members 3F (vertical connecting members 3F) to which the unit frame 20 of the first mounting unit 4A and the unit frame 20 of the third mounting unit 4C are connected, respectively. The vertical connecting members 3F are located on the inner circumference side (opening 3A side) of the frame 3 and protrude from the frame 3. In addition, the vertical connecting members 3F are located at the respective openings 3A of the vertical frames 7 and 8, attached to the vertical frames 7 and 8, and protrude from the vertical frames 7 and 8 toward the openings 3A. Multiple vertical connecting members 3F are provided at various locations along the longitudinal direction of each of the vertical frames 7 and 8.

[0046] The curtain wall 1 is equipped with fastening components 52 (vertical fastening components 52) that fix the unit frame 20 of the first mounting unit 4A and the unit frame 20 of the third mounting unit 4C to the frame 3. The vertical fastening components 52 are fastening components that detachably fix the unit frame 20 to the frame 3 by fastening, and in this case, they are bolts that connect the vertical connecting member 28 to the vertical connected member 3F. The unit frame 20 of the first mounting unit 4A and the unit frame 20 of the third mounting unit 4C are each positioned inside the frame 3 (opening 3A), spaced apart from the frame 3 in the left-right direction S, and facing the frame 3 with a gap 62 between them. The vertical connecting member 28, the vertical connected member 3F, and the vertical fastening components 52 are located in the gap 62 (space) between the frame 3 and the unit frame 20.

[0047] The vertical connecting member 28 contacts the vertical connecting member 3F from the outdoor side and is positioned overlapping the vertical connecting member 3F. The vertical fastening component 52 is inserted from the indoor side through an insertion hole formed in the vertical connecting member 3F and screwed from the indoor side into a screw hole formed in the vertical connecting member 28. In this way, the vertical fastening component 52 is attached to the vertical connecting member 28 and fastens the vertical connecting member 28 and the vertical connecting member 3F. Between the frame 3 and the unit frame 20, the vertical fastening component 52 fastens and fixes the unit frame 20 to the frame 3 via the vertical connecting member 28 and the vertical connecting member 3F.

[0048] The vertical connecting member 28 is connected to the vertical connecting member 3F by vertical fastening component 52, thereby connecting the unit frame 20 to the vertical connecting member 3F and the frame body 3. The unit frame 20 is fixed to the frame body 3 via the vertical connecting member 28, vertical fastening component 52, and vertical connecting member 3F. The vertical connecting member 28 also connects the first vertical frame member 24 of the unit frame 20 of the first mounting unit 4A to the vertical connecting member 3F of the frame body 3, and connects the second vertical frame member 25 of the unit frame 20 of the third mounting unit 4C to the vertical connecting member 3F of the frame body 3. The vertical frame members 24 and 25 are connected and fixed to the vertical frames 7 and 8 at multiple locations along the longitudinal direction of the vertical frame members 24 and 25 via the vertical connecting member 28, vertical fastening component 52, and vertical connecting member 3F.

[0049] The gap 62 between the frame 3 and the unit frame 20 is an open space facing inward. The gap 62 between the vertical frames 7 and 8 of the frame 3 and the vertical frame members 24 and 25 of the unit frame 20 is sealed on the inward side by a sealant 73. The sealant 73 is located on the inward side of the vertical connecting member 28, the vertical connected member 3F, and the vertical fastening component 52, and is provided between the vertical frames 7 and 8 and the vertical frame members 24 and 25. The vertical connecting member 28, the vertical connected member 3F, and the vertical fastening component 52 are located on the outward side of the sealant 73 within the gap 62 and are shielded on the inward side by the sealant 73. The gap 63 (see Figure 13) between the unit frames 20 (vertical frame members 24 and 25) of adjacent mounting units 4A, 4B, and 4C is sealed on the inward side by a sealant 74.

[0050] With the cover 70 and sealing materials 71-74 absent (see Figures 10-14), the unit frames 20 of the mounting units 4A, 4B, and 4C are fixed to the frame 3 by fastening components 50-52. When removing the unit frames 20 and mounting units 4A, 4B, and 4C from the frame 3, the fastening components 50-52 can release the unit frames 20 from the frame 3. The fastening components 50 can be used to fix and release the unit frames 20 from the frame 3. The fastening components 50 can be used to fix and release the unit frames 20 from the frame 3 of the curtain wall 1 installed in the building 10. On the indoor side of the frame 3, the fastening components 50-52 are attached to the connecting members 26-28 from the indoor side, thereby fixing the unit frames 20 to the frame 3. The fastening components 50-52 are removed from the connecting members 26-28 to the indoor side, thereby releasing the unit frames 20 from the frame 3.

[0051] In this manner, the unit frames 20 of the mounting units 4A, 4B, and 4C are fixed to the frame 3 from the indoor side by fastening components 50-52, and the fastening components 50-52 release the fixation to the frame 3 from the indoor side. The fastening components 50-52 release the fastening of the connecting members 26-28 to the connected members 3D, 3E, and 3F, and the fastening of the unit frame 20 to the frame 3, thereby releasing the fixation of the unit frame 20 to the frame 3. With the fixation of the unit frame 20 to the frame 3 released by the fastening components 50-52, the unit frames 20 and the mounting units 4A, 4B, and 4C move away from the frame 3 to the outdoor side and are removed from the frame 3 to the outdoor side.

[0052] Figures 15 and 16 show a portion of the curtain wall 1 of this embodiment. Figures 15A and 16A are front views of a portion of the curtain wall 1 as seen from the outside. Figure 15B is a longitudinal cross-sectional view of a portion of the curtain wall 1 cut along the line X1-X1 in Figure 15A, and Figure 16B is a longitudinal cross-sectional view of a portion of the curtain wall 1 cut along the line X2-X2 in Figure 16A.

[0053] As shown in the figure, the mounting units 4A, 4B, and 4C have a through-hole 80 that penetrates the mounting bodies 30 and 40 in the indoor / outdoor direction T, upper and lower transoms 81 and 82 (first transom 81 and second transom 82) provided above and below the through-hole 80, and removable sealing members 34 and 41 (first sealing member 34 and second sealing member 41) that close the through-hole 80. The through-hole 80 is an opening (through-hole) located on the inside (opening 3A) of the frame 3 and is open to the outdoor and indoor sides of the mounting units 4A, 4B, and 4C. Furthermore, the through-hole 80 is formed at two locations separated in the left-right direction S between the upper end and the center in the vertical direction R of the opening 3A of the frame 3 and the mounting bodies 30 and 40 (see the two first sealing members 34 of each of the mounting units 4A, 4B, and 4C shown in Figure 5).

[0054] In each of the mounting units 4A, 4B, and 4C, the two through-holes 80 are formed spaced apart from each other in the left-right direction S. The transoms 81 and 82 extend laterally between the upper frame member 22 and the lower frame member 23 of the unit frame 20, are located on the indoor side of the first mounting body 30, and are mounted on the left and right vertical frame members 24 and 25. The first transom 81 is an upper transom located above the second transom 82 and the through-hole 80, and the second transom 82 is a lower transom located below the first transom 81 and the through-hole 80. In the vertical direction R, the first transom 81 and the second transom 82 face each other with the through-hole 80 in between, and each faces the through-hole 80.

[0055] The first mounting body 30 and the vane 31 are divided vertically at the through-hole 80. The through-hole 80 is located in the vertical direction R between the vertically divided first mounting body 30 (vane 31) and between the first transom 81 and the second transom 82. The second mounting body 40 is divided vertically at the through-hole 80 and the transoms 81 and 82, and is provided above the first transom 81 and below the second transom 82, and is attached to the first transom 81 and the second transom 82, respectively. The sealing members 34 and 41 are positioned in the through-hole 80 and attached to the mounting units 4A, 4B, and 4C (here, the transoms 81 and 82), and are detachably attached to the through-hole 80. By attaching the sealing materials 34 and 41 to the penetration 80, the penetration 80 is closed, and by removing the sealing materials 34 and 41 from the penetration 80, the penetration 80 is opened.

[0056] The first sealing member 34 is an outdoor sealing member that seals the outdoor side of the penetration 80 and is located on the outdoor side of the second sealing member 41. The first sealing member 34 also has a plurality of vanes 35 arranged in parallel. The plurality of vanes 35, like the plurality of vanes 31 of the first mounting body 30, each extends in the vertical direction R and is spaced apart from each other in the left-right direction S. At the location of the penetration 80, the first sealing member 34 is positioned between the vertically divided first mounting body 30 (vanes 31) and is also positioned on the outdoor side of the transoms 81 and 82, and is detachably attached to the transoms 81 and 82. The first sealing member 34 is removed from the transoms 81 and 82 and removed from the penetration 80 toward the outdoor side.

[0057] The second sealing material 41 is an indoor-side sealing material that closes the indoor-side portion of the penetration 80, and is located on the indoor side of the first sealing material 34. The second sealing material 41, like the second mounting body 40, is a panel and closes the penetration 80. At the location of the penetration 80, the second sealing material 41 is positioned between the first transom 81 and the second transom 82 and is detachably attached to the transoms 81 and 82. The second sealing material 41 is removed from the transoms 81 and 82 and then removed from the penetration 80 toward the indoor side.

[0058] Mounting units 4A, 4B, and 4C are removed from the frame 3 by being suspended at the penetration 80 using a suspension jig 83 (see Figure 16). The penetration 80 is a cavity used for installing the suspension jig 83 on the mounting units 4A, 4B, and 4C. The suspension jig 83 is a jig for suspending the mounting units 4A, 4B, and 4C, and penetrates the penetration 80 in the indoor / outdoor direction T, and is positioned inside the penetration 80. The suspension jig 83 is also located inside the penetration 80, below the first transom 81, and contacts the first transom 81 from below. The suspension jig 83 protrudes from the penetration 80 toward the outdoor side and the indoor side, respectively, and at a point on the indoor side of the penetration 80, it is located on the indoor side of the first transom 81 and contacts the first transom 81 from the indoor side.

[0059] When the mounting units 4A, 4B, and 4C are removed from the frame 3, the sealing materials 34 and 41 are removed from the penetration 80, and the penetration 80 is opened. In this state, the hanging jigs 83 of the mounting units 4A, 4B, and 4C are placed in the penetration 80 and fixed to the mounting units 4A, 4B, and 4C (in this case, the first transom 81) by two fasteners 84 and 85 (first fastener 84, second fastener 85), which are bolts. The hanging jigs 83 are fixed to the indoor side of the first transom 81 by the first fastener 84 and to the lower side of the first transom 81 by the second fastener 85. The sealing materials 34 and 41 are attached to the penetration 80 when the hanging jigs 83 are not placed in the penetration 80, thereby closing the penetration 80.

[0060] Figure 17 is a longitudinal cross-sectional view showing the procedure for removing the mounting units 4A, 4B, and 4C of the curtain wall 1 in this embodiment from the frame 3. As shown in the diagram, with the curtain wall 1 installed on the exterior wall 11 of the building 10 (see Figure 17A), the sealing materials 34 and 41 are removed from the penetration 80 to open the penetration 80 (see Figure 17B). Next, the hanging jig 83 is placed in the penetration 80 and fixed to the first transom 81 and the mounting units 4A, 4B, and 4C (see Figure 17C). Also, the cover 70 and sealing materials 71-74 are removed from the curtain wall 1, and the fastening parts 50-52 are removed to release the fastening parts 50-52 from fixing the unit frame 20 to the frame 3.

[0061] The lifting jig 83 protrudes to the outside from the penetration 80, the first mounting body 30, and the mounting units 4A, 4B, and 4C. A lifting device (not shown) is connected to the lifting jig 83, and the mounting units 4A, 4B, and 4C are lifted by the lifting device via the lifting jig 83 (see Figure 17D). The lifting device is, for example, a crane, and is connected to the lifting jig 83 by a lifting wire 86 and a hook 87. The mounting units 4A, 4B, and 4C are removed from the frame 3 to the outside while suspended using the lifting jig 83, and separated from the frame 3. This opens the opening 3A of the frame 3.

[0062] As described above, in the curtain wall 1 of this embodiment, the mounting units 4A, 4B, and 4C can be easily removed from the frame 3 installed in the building 10. Furthermore, the fastening components 50-52 are positioned so that they can be released from the indoor side of the curtain wall 1, preventing them from being exposed to the outdoor side of the curtain wall 1. The unit frame 20 can also be easily released from the frame 3 on the indoor side of the frame 3. Therefore, the mounting units 4A, 4B, and 4C can be easily removed from the frame 3 while maintaining the aesthetic appeal of the curtain wall 1.

[0063] When removing the mounting units 4A, 4B, and 4C from the frame 3, the hanging jig 83 can be easily attached to the mounting units 4A, 4B, and 4C by removing the sealing materials 34 and 41 from the penetration 80. Furthermore, the penetration 80 can be sealed with the sealing materials 34 and 41 while the mounting units 4A, 4B, and 4C are attached to the frame 3. Therefore, the mounting units 4A, 4B, and 4C can be easily removed from the frame 3 using the hanging jig 83 while maintaining the aesthetic appearance of the curtain wall 1.

[0064] Multiple mounting units 4A, 4B, and 4C are arranged side by side in the opening 3A of the frame 3, and each of the multiple mounting units 4A, 4B, and 4C can be easily removed from the frame 3. In addition, multiple vanes 31 are arranged side by side on the first mounting body 30, and the mounting units 4A, 4B, and 4C having multiple vanes 31 can be easily removed from the frame 3.

[0065] Furthermore, the multiple vanes 31 of the first mounting unit 30 are not limited to vanes extending in the vertical direction R, but may also extend in other directions (for example, the left-right direction S). Also, multiple mounting units 30, 40 may be mounted in the opening 21 of the unit frame 20, or only one mounting unit may be mounted in the opening 21 of the unit frame 20. For example, if the curtain wall 1 is a ventilated curtain wall that allows ventilation between the inside and outside, only the first mounting unit 30 (louver) having multiple vanes 31 is mounted in the opening 21 of the unit frame 20. The curtain wall 1 may have only one mounting unit, or it may have multiple mounting units.

[0066] The frame 3 may have multiple upper and lower members between a pair of divided frame sections 3B and 3C, or it may have only a pair of divided frame sections 3B and 3C. Alternatively, the frame 3 may be a frame that is not divided into multiple parts. In this case, the upper frame 5 and the lower frame 6 are not divided in their respective longitudinal directions. Furthermore, the ends of the upper frame 5, the lower frame 6, and the left and right vertical frames 7 and 8 of the frame 3 are connected to each other to frame the frames 5 to 8. The present invention can be applied to various curtain walls equipped with a frame and at least one mounting unit.
