The -Y direction is the direction from the outside to the inside of the building 1 and can also be referred to as the indoor side.

[0017] The curtain wall 10 has a plurality of panel units 11 and a plurality of catch pans 12. The catch pan 12 is an example of a partition member. Each of the plurality of panel units 11 has a panel 21 and a frame 22. The panel 21 is an example of an outer wall material.

[0018] The panel 21 is, for example, a substantially rectangular plate made of multi-layer glass, ordinary concrete, lightweight concrete, or metal. Note that the panel 21 may be made of other materials. The upper edge 21a and the lower edge 21b of the panel 21 extend substantially in the X direction. The edge 21b is located below the edge 21a. The side (left and right) edges 21c, 21d of the panel 21 extend substantially in the Z direction.

[0019] The frame 22 has an upper frame 31, a lower frame 32, and two vertical frames 33, 34. The upper frame 31, the lower frame 32, and the vertical frames 33, 34 are made of a metal such as aluminum, for example. Note that a part of the upper frame 31, the lower frame 32, and the vertical frames 33, 34 may be made of other materials.

[0020] The upper frame 31 is attached to the upper edge 21a of the panel 21 and extends substantially in the X direction. The lower frame 32 is attached to the lower edge 21b of the panel 21 and extends substantially in the X direction.

The panel 21 is surrounded by the upper frame 31, the lower frame 32, and the two vertical frames 33, 34.

[0021] The plurality of panel units 11 are arranged in the vertical and horizontal directions. In the curtain wall 10, four panel units 11 are combined so as to sandwich a catch pan 12 at the corner of the adjacent panel units 11. For example, the vertical frames 33, 34 of two panel units 11 adjacent to each other in the horizontal direction form a mullion. Each of the plurality of panel units 11 is attached to the building body 1 of the building 1 by, for example, fasteners.

[0022] Hereinafter, the four panel units 11 may be individually referred to as panel units 11UL, 11UR, 11LL, and 11LR. The panel unit 11UL is an example of the first panel unit. The panel unit 11UR is an example of the second panel unit. The panel unit 11LL is an example of the third panel unit.

[0023] The panel unit 11UR is adjacent to the panel unit 11UL in the horizontal direction. The panel unit 11LL is adjacent to the panel unit 11UL in the vertical direction. The panel unit 11LR is adjacent to the panel unit 11UR in the vertical direction. The panel units 11LL, 11LR are located below the panel units 11UL, 11UR.

[0024] Figure 2 is a cross-sectional view showing a portion of the curtain wall 10 of this embodiment along the line F2-F2 in Figure 1. As shown in Figure 2, the lower frame 32 has a plurality of recessed walls 41, 42, 43 and a plurality of visible walls 44, 45, 46.

[0025] The exterior walls 41, 42, and 43 are formed in a plate-like shape that extends along the XY plane. In the vertical direction, exterior wall 41 is located below exterior walls 42 and 43, and exterior wall 43 is located between exterior walls 41 and 42.

[0026] The visible walls 44, 45, and 46 are formed in a plate-like shape that extends along the XZ plane. In the depth direction, visible wall 44 is located on the outdoor side of visible walls 45 and 46, and visible wall 46 is located between visible walls 44 and 45.

[0027] The visible wall 44 projects upward from approximately the center of the visible wall 41 in the depth direction. The visible wall 44 supports the panel 21 in the depth direction. The visible wall 42 extends inward from the upper end of the visible wall 44.

[0028] The visible wall 46 extends upward from the end of the interior wall 41 on the indoor side. The interior wall 43 extends inward from the end of the visible wall 46 approximately above. The visible wall 45 extends downward from the end of the interior wall 42 on the indoor side. The end of the interior wall 43 on the indoor side is connected to the visible wall 45.

[0029] The upper frame 31 has a plurality of facade walls 51, 52 and a plurality of facade walls 53, 54, 55. The facade walls 51, 52 are formed in a plate-like shape that extends along the XY plane. In the vertical direction, the facade wall 52 is located below the facade wall 51.

[0030] The visible walls 53, 54, and 55 are formed in a plate-like shape that extends along the XZ plane. In the depth direction, visible wall 53 is located on the outdoor side of visible walls 54 and 55, and visible wall 55 is located between visible walls 53 and 54.

[0031] The visible wall 53 protrudes downward from approximately the center of the visible wall 51 in the depth direction. The visible wall 54 protrudes downward from the end of the visible wall 51 on the indoor side. The visible wall 52 extends in the depth direction between the lower end of the visible wall 53 and the lower end of the visible wall 54. The visible wall 55 protrudes upward from the visible wall 51. The visible wall 55 of the upper frame 31 is inserted into the space between the two visible walls 45 and 46 of the lower frame 32.

[0032] The curtain wall 10 further includes sealants 61, 62, and 63. The sealants 61, 62, and 63 are made of an elastic material such as ethylene propylene diene (EPDM) rubber. The sealants 61 and 62 are rain barriers and are located on the outdoor side of the sealant 63. The sealant 63 is a wind barrier and is located on the indoor side of the sealants 61 and 62.

[0033] The sealant 61 is located on the outdoor side of the sealant 62. The sealant 61 protrudes upward from the facade wall 51 of the upper frame 31 and abuts against the facade wall 41 of the lower frame 32. The sealant 62 protrudes downward from the facade wall 41 of the lower frame 32 and abuts against the facade wall 51 of the upper frame 31. The sealant 63 protrudes outward from the facade wall 55 of the upper frame 31 and abuts against the facade wall 46 of the lower frame 32.

[0034] Multiple lateral isobaric spaces SL are provided in the curtain wall 10. A lateral isobaric space SL is an example of a second isobaric space. At least one of the multiple lateral isobaric spaces SL is provided between the lower frame 32 of panel unit 11UL and the upper frame 31 of panel unit 11LL. At least one of the multiple lateral isobaric spaces SL is provided between the lower frame 32 of panel unit 11UR and the upper frame 31 of panel unit 11LR.

[0035] The transverse isobaric space SL between panel units 11UL and 11LL is approximately equal to the transverse isobaric space SL between panel units 11UR and 11LR. The following explanation will mainly focus on the transverse isobaric space SL between panel units 11UL and 11LL.

[0036] The lateral isobaric space SL has a first region SL1 and a second region SL2. The first region SL1 is the space between the lower frame 32 of panel unit 11UL and the upper frame 31 of panel unit 11LL, specifically the portion between sealing material 62 and sealing material 63. Each of the sealing materials 62 and 63 extends in the left-right direction and seals the end of the first region SL1.

[0037] The second region SL2 is the space between the lower frame 32 of panel unit 11UL and the upper frame 31 of panel unit 11LL, specifically the portion between sealant 61 and sealant 62. Each of the sealants 61 and 62 extends in the left-right direction and seals the end of the second region SL2.

[0038] The lateral isobaric space SL is connected to the outdoors, for example, through a hole provided in at least one of the upper frame 31 and the lower frame 32. This keeps the lateral isobaric space SL at approximately equal pressure with the outdoors, suppressing rainwater from entering the building due to pressure differences or airflow. Note that the atmospheric pressure in the lateral isobaric space SL and the atmospheric pressure outdoors may temporarily differ.

[0039] Figure 3 is a cross-sectional view showing a portion of the curtain wall 10 of this embodiment along the line F3-F3 in Figure 1. As shown in Figure 3, the vertical frame 34 has a plurality of recessed walls 71, 72, 73 and a plurality of visible walls 74, 75, 76, 77.

[0040] The facade walls 71, 72, and 73 are formed in a plate-like shape that extends along the YZ plane. In the left-right direction, facade wall 71 is located to the right (+X direction) of facade walls 72 and 73, and facade wall 73 is located between facade walls 71 and 72.

[0041] The visible walls 74, 75, 76, and 77 are formed in a plate-like shape that extends along the XZ plane. In the depth direction, visible wall 74 is located on the outdoor side of visible walls 75, 76, and 77, and visible walls 76 and 77 are located between visible walls 74 and 75.

[0042] The visible wall 74 extends horizontally between the end of the interior wall 71 on the indoor side and the end of the interior wall 72 on the outdoor side. The visible wall 74 supports the panel 21 in the interior direction. The visible wall 75 extends to the right from the end of the interior wall 72 on the indoor side.

[0043] The visible walls 76 and 77 project to the right from approximately the center of the visible wall 72 in the depth direction. The visible walls 76 and 77 are spaced apart from each other in the depth direction. The visible wall 73 extends in the depth direction between approximately the center of the visible wall 76 in the left-right direction and approximately the center of the visible wall 77 in the left-right direction.

[0044] The vertical frame 33 has multiple facade walls 81, 82, 83 and multiple face walls 84, 85, 86, 87. The facade walls 81, 82, 83 are formed in a plate-like shape that extends along the YZ plane. In the left-right direction, facade wall 83 is located to the left (-X direction) of facade walls 81, 82, and facade wall 81 is located between facade walls 82, 83.

[0045] The visible walls 84, 85, 86, and 87 are formed in a plate-like shape that extends along the XZ plane. In the depth direction, visible wall 84 is located on the outdoor side of visible walls 85, 86, and 87, and visible walls 86 and 87 are located between visible walls 84 and 85.

[0046] The visible wall 84 extends horizontally between the end of the interior wall 81 on the indoor side and the end of the interior wall 82 on the outdoor side. The visible wall 84 supports the panel 21 in the interior direction. The visible wall 85 extends to the left from the end of the interior wall 82 on the indoor side. The visible wall 85 of the vertical frame 33 is combined with the visible wall 75 of the vertical frame 34.

[0047] The visible walls 86 and 87 project to the left from approximately the center of the visible wall 82 in the depth direction. The visible walls 86 and 87 are spaced apart from each other in the depth direction. The ends of the visible walls 86 and 87 on the left are located between the visible walls 76 and 77 of the vertical frame 34. The visible wall 83 extends in the depth direction between approximately the center of the visible wall 86 in the left-right direction and approximately the center of the visible wall 87 in the left-right direction.

[0048] The curtain wall 10 further includes sealants 91 and 92. The sealants 91 and 92 are made of an elastic material such as EPDM rubber. Sealant 91 is a rain barrier and is located on the outdoor side of sealant 92. Sealant 92 is a wind barrier and is located on the indoor side of sealant 91.

[0049] The sealant 91 protrudes from the visible wall 86 of the vertical frame 33 and abuts against the visible wall 76 of the vertical frame 34. The sealant 92 protrudes from the visible wall 87 of the vertical frame 33 and abuts against the visible wall 77 of the vertical frame 34.

[0050] Multiple vertical isobaric spaces SV are provided in the curtain wall 10. A vertical isobaric space SV is an example of a first isobaric space. At least one of the multiple vertical isobaric spaces SV is provided between the vertical frame 34 of panel unit 11UL and the vertical frame 33 of panel unit 11UR. At least one other of the multiple vertical isobaric spaces SV is provided between the vertical frame 34 of panel unit 11LL and the vertical frame 33 of panel unit 11LR.

[0051] The longitudinal isobaric space SV between panel units 11UL and 11UR and the longitudinal isobaric space SV between panel units 11LL and 11LR are approximately equal to each other. The following explanation will mainly focus on the longitudinal isobaric space SV between panel units 11UL and 11UR.

[0052] The longitudinal isobaric space SV is the portion of the space between the vertical frame 34 of panel unit 11UL and the vertical frame 33 of panel unit 11UR, specifically the portion between sealing material 91 and sealing material 92. Each of the sealing materials 91 and 92 extends vertically and seals the end of the longitudinal isobaric space SV.

[0053] The vertical isobaric space SV is connected to the outdoors, for example, through a hole provided in at least one of the vertical frames 33 and 34. This keeps the vertical isobaric space SV at approximately the same pressure as the outdoors, suppressing rainwater from entering the building due to pressure differences or airflow, for example. Note that the atmospheric pressure in the vertical isobaric space SV and the atmospheric pressure outdoors may temporarily differ.

[0054] Figure 4 is a perspective view showing the panel units 11LL, 11LR and the catch pan 12 of this embodiment. The catch pan 12 is made of, for example, a silicone sponge manufactured by adding a foaming agent to a silicone material, and is elastic. The catch pan 12 may be made of other elastic materials. The catch pan 12 has a longitudinal septum 101 and two transverse septums 102 and 103.

[0055] The longitudinal septum 101 is formed in a roughly rectangular parallelepiped shape. The longitudinal septum 101 is sandwiched between the lower end of the vertical frame 34 of panel unit 11UL and the upper end of the vertical frame 34 of panel unit 11LL. Furthermore, the longitudinal septum 101 is sandwiched between the lower end of the vertical frame 33 of panel unit 11UR and the upper end of the vertical frame 33 of panel unit LR.

[0056] The longitudinal stubble 101 covers the lower end of the longitudinal isobaric space SV located between the panel units 11UL and 11UR. Furthermore, the longitudinal stubble 101 covers the upper end of the longitudinal isobaric space SV located between the panel units 11LL and 11LR.

[0057] The transverse diaphragms 102 and 103 protrude outward from the longitudinal diaphragm 101. The two transverse diaphragms 102 and 103 are spaced apart from each other in the left-right direction.

[0058] The lateral bulkhead 102 abuts against the lower ends of the internal walls 41 and 43 and the right end of the external walls 45 and 46 of the lower frame 32 of the panel unit 11UL. The lateral bulkhead 102 abuts against the upper end of the internal wall 51 and the right end of the external wall 55 of the upper frame 31 of the panel unit 11LL. Furthermore, the lateral bulkhead 102 abuts against the right end of the sealing materials 62 and 63.

[0059] The lateral bulkhead 103 abuts against the lower ends of the internal walls 41 and 43 and the left end of the external walls 45 and 46 of the lower frame 32 of the panel unit 11UL. The lateral bulkhead 103 abuts against the upper end of the internal wall 51 and the left end of the external wall 55 of the upper frame 31 of the panel unit 11LL. Furthermore, the lateral bulkhead 103 abuts against the left end of the sealing materials 62 and 63.

[0060] The catch pan 12, having transverse diaphragms 102 and 103, is sandwiched between the lower frame 32 of panel unit 11UL and the lower frame 32 of panel unit 11UR. Furthermore, the catch pan 12 is sandwiched between the upper frame 31 of panel unit 11LL and the upper frame 31 of panel unit 11LR. The portion of the catch pan 12 that comes into contact with the upper frame 31, the lower frame 32, or the vertical frames 33 and 34 is elastically crushed (compressed) and can adhere tightly to the upper frame 31, the lower frame 32, or the vertical frames 33 and 34.

[0061] The transverse diaphragm 102 covers the right end of the first region SL1 of the transverse isobaric space SL located between panel units 11UL and 11LL. The transverse diaphragm 103 covers the left end of the first region SL1 of the transverse isobaric space SL located between panel units 11UR and 11LR.

[0062] As described above, the lateral isobaric space SL is a defined (partitioned, formed) space enclosed by the catch pan 12, upper frame 31, lower frame 32, and sealing materials 61, 62, and 63. Similarly, the longitudinal isobaric space SV is a defined space enclosed by the catch pan 12, longitudinal frames 33, 34, and sealing materials 91, 92.

[0063] The longitudinal septum 101 of the catch pan 12 almost completely blocks both ends of the longitudinal isobaric space SV in the vertical direction. Furthermore, the transverse septums 102 and 103 of the catch pan 12 almost completely block both ends of the transverse isobaric space SL in the left-right direction. Therefore, the catch pan 12 separates the transverse isobaric space SL from the longitudinal isobaric space SV.

[0064] As shown in Figure 3, in this embodiment, a gondola rail SG is provided inside the inner walls 71, 72 and outer walls 74, 76 of the vertical frame 33, and inside walls 81, 82 and outer walls 84, 86 of the vertical frame 34. The gondola rail SG communicates with the outdoors and is substantially part of the outdoors.

[0065] The longitudinal bulkhead 101 separates the longitudinal isobaric space SV from the gondola rail SG. The transverse bulkheads 102 and 103 each separate the transverse isobaric space SL from the gondola rail SG. The longitudinal isobaric space SV and the transverse isobaric space SL are separated by the catch pan 12 and the gondola rail SG.

[0066] As shown in Figure 4, the longitudinal partition wall 101 has an upper surface 101a and an outer surface 101b. The upper surface 101a faces upward. The upper surface 101a covers the lower end of the longitudinal isobaric space SV between the panel units 11UL and 11UR. The outer surface 101b faces the outside. The outer surface 101b faces the gondola rail SG.

[0067] A drainage channel 105 is provided in the vertical partition wall 101. The drainage channel 105 opens to the upper surface 101a and the outer surface 101b. Therefore, the drainage channel 105 connects the lower end of the vertical isobaric space SV between the panel units 11UL and 11UR to the gondola rail SG (outdoors). Water in the vertical isobaric space SV is discharged from the drainage channel 105 to the gondola rail SG.

[0068] As shown in Figures 2 and 3, the end SLi of the horizontal isobaric space SL on the indoor side is located on the outdoor side than the end SVi of the vertical isobaric space SV on the indoor side. The ends SLi and SVi can also be called airtight lines. Furthermore, the end SLi of the horizontal isobaric space SL on the indoor side is located on the outdoor side than the end SVo of the vertical isobaric space SV on the outdoor side. That is, in the depth direction, the entire area of ​​the horizontal isobaric space SL is located on the outdoor side of the vertical isobaric space SV. In the depth direction, the dimensions of the upper frame 31 and the lower frame 32 are shorter than the dimensions of the vertical frames 33 and 34. Note that in the depth direction, a part of the horizontal isobaric space SL may be located on the indoor side of a part of the vertical isobaric space SV.

[0069] In the curtain wall 10 according to the embodiment described above, a vertical isobaric space SV is provided between the vertical frame 34 of panel unit 11UL and the vertical frame 33 of panel unit 11UR. A horizontal isobaric space SL is provided between the lower frame 32 of panel unit 11UL and the upper frame 31 of panel unit 11LL. The end SLi of the horizontal isobaric space SL on the indoor side is located on the outdoor side than the end SVi of the vertical isobaric space SV on the indoor side. As a result, in the depth direction, the dimensions of the upper frame 31 and lower frame 32 can be shorter than the dimensions of the vertical frames 33 and 34. Setting a longer depth dimension for the vertical frames 33 and 34, which can be subjected to greater loads, suppresses a decrease in the strength of the curtain wall 10. On the other hand, by shortening the dimensions of the upper frame 31 and lower frame 32 in the depth direction, the curtain wall 10 can miniaturize the upper frame 31 and lower frame 32, and consequently reduce the weight and cost of the upper frame 31 and lower frame 32.

[0070] The curtain wall 10 further includes an elastic catch pan 12. The catch pan 12 is sandwiched between the lower frame 32 of panel unit 11UL and the lower frame 32 of panel unit 11UR, and also sandwiched between the vertical frame 34 of panel unit 11UL and the vertical frame 34 of panel unit 11LL. The catch pan 12 separates the vertical isobaric space SV and the horizontal isobaric space SL. That is, the vertical isobaric space SV and the horizontal isobaric space SL are independent of each other, making it easy to make the positions of the vertical isobaric space SV and the horizontal isobaric space SL different in the depth direction. In addition, it is easy to maintain the atmospheric pressure in each of the vertical isobaric space SV and the horizontal isobaric space SL to be approximately equal to the outside air.

[0071] The catch pan 12 covers the lower end of the vertical isobaric space SV. A drainage channel 105 is provided in the catch pan 12, connecting the lower end of the vertical isobaric space SV to the outdoors. This allows water in the vertical isobaric space SV to be discharged through the drainage channel 105. Furthermore, since the catch pan 12, which separates the vertical isobaric space SV and the horizontal isobaric space SL, also serves as a component for discharging water from the vertical isobaric space SV, the cost of the curtain wall 10 can be reduced.

[0072] The catch pan 12 covers one end of the lateral isobaric space SL. This improves the airtightness of the lateral isobaric space SL.

[0073] The end SLi of the horizontal isobaric space SL on the indoor side is located further outdoors than the end SVO of the vertical isobaric space SV on the outdoor side. In other words, the entire horizontal isobaric space SL is located further outdoors than the vertical isobaric space SV. As a result, the curtain wall 10 can reduce the size of the upper frame 31 and the lower frame 32, and consequently reduce the weight and cost of the upper frame 31 and the lower frame 32.

[0074] The embodiments of the present invention described above are not intended to limit the scope of the invention, but are merely examples that fall within the scope of the invention. Some embodiments of the present invention may be modified, omitted, or added to the embodiments described above, for example, with respect to at least some of the specific uses, structures, shapes, functions, and effects, without departing from the spirit of the invention.

[0075] The Sustainable Development Goals (SDGs) are 17 international goals adopted at the UN Summit in September 2015. The curtain wall 10 according to this embodiment can contribute to achieving some of the 17 SDGs, such as Goal 11, "Make cities and human settlements inclusive, safe, resilient and sustainable."
