Description

[Technical Field]

[0001] The present invention relates to a curtain wall unit having protruding members attached to vertical frames. [Background technology]

[0002] Curtain wall units are installed side by side in the left-right and up-down directions to form the exterior wall of a building. Curtain wall units lined up in the left-right direction on the exterior wall of a building form joints between their vertical frames. Also, a conventional curtain wall is known in which a gondola guide attached to a gondola comes into contact with a wind guard attached to the vertical frame when the gondola guide moves between the vertical frames (see Patent Document 1).

[0003] In the conventional curtain wall described in Patent Document 1, the wind guards are protruding members that protrude toward the joints between the vertical frames and prevent outside air from entering the interior area between the vertical frames. However, when the gondola guide moves, the wind guards may move vertically due to external forces applied by the gondola guide. There is also concern that the wind guards may move downward due to their own weight even when not in contact with the gondola guide. If the wind guards move vertically and their position shifts vertically, there is concern that their attachment position relative to the vertical frames may shift, affecting the function of the wind guards.

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the curtain wall unit of the present invention will be described with reference to the drawings. The curtain wall unit of this embodiment is used in the curtain wall of a building and is installed on the exterior wall of the building. Multiple curtain wall units are combined with each other to form part of the curtain wall. The curtain wall unit and curtain wall are installed on the exterior wall of the building, between the indoor (indoor) and outdoor (outdoor) sides of the building, to form the exterior wall of the building. Two embodiments of the curtain wall unit will be described below in order.

[0010] (First embodiment) FIG. 1 is a front view showing the curtain wall 1 of the first embodiment, showing the curtain wall 1 and curtain wall unit 2 installed in a building 10 as viewed from the outdoor side. FIG. 2 is a longitudinal cross-sectional view showing the curtain wall 1 of the first embodiment, showing the curtain wall 1 and a part of the building 10 cut along line X1-X1 in FIG. 1. FIG. 3 is a transverse cross-sectional view showing the curtain wall 1 of the first embodiment, showing the curtain wall 1 cut along line X2-X2 in FIG. 1.

[0011] As shown in the figure, the curtain wall 1 comprises a plurality of curtain wall units 2 installed side by side on a building 10. The curtain wall units 2 are panel units that make up the curtain wall 1, and are pre-assembled before installation on the building 10. The curtain wall 1 and the curtain wall units 2 are installed in locations on the exterior wall 11 of the building 10, and form the exterior wall 11 of the building 10. The curtain wall units 2 are installed side by side in the vertical direction R and the horizontal direction S, and are connected to each other with adjacent curtain wall units 2. The curtain wall 1 and the curtain wall units 2 are arranged on the outdoor side of the skeleton 12 of the building 10, and are attached to the skeleton 12 of the building 10.

[0012] When the curtain wall 1 and the curtain wall unit 2 installed in the building 10 are 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) of the curtain wall 1 and the curtain wall unit 2 installed in the building 10. Furthermore, the indoor-outdoor direction T is the front-to-back direction (depth direction) and the thickness direction of the curtain wall 1 and the curtain wall unit 2 when viewed from the front of the curtain wall 1 and the curtain wall unit 2 installed in the building 10, and in FIG. 3 is the horizontal direction perpendicular to the left-to-right direction S. Thus, the directions of the curtain wall 1 and the curtain wall unit 2 are specified by the directions when they are installed in the building 10. Furthermore, the indoor side and the outdoor side of the curtain wall 1 and the curtain wall unit 2 are the indoor side and the outdoor side when they are installed in the building 10.

[0013] The curtain wall unit 2 comprises two upper and lower panels 2A and a frame 3 surrounding the panels 2A. The panels 2A are rectangular glass panels (for example, plate glass, double-glazed glass, or laminated glass) that are placed in openings 3A in the frame 3 and are held by the frame 3. The panels 2A are fixed panels that are fixed to the rectangular openings 3A in the frame 3 and close the openings 3A in the frame 3. The frame 3 is a rectangular opening frame that forms the openings 3A, and is placed on the outdoor side of the skeleton 12 of the building 10 and attached to the skeleton 12 of the building 10. The frames 3 of the multiple curtain wall units 2 are each connected to the frame 3 of an adjacent curtain wall unit 2.

[0014] The frame body 3 has four frames 4-6 (an upper frame 4, a lower frame 5, and a pair of vertical frames 6) and a crossbeam 7 that are combined with each other, and the frames 4-6 and the crossbeam 7 form two openings 3A, one at the top and one at the bottom. The frames 4-6 and the crossbeam 7 of the frame body 3 are frame materials (frame components) that make up the frame body 3, and are each made of a metal (for example, aluminum alloy) shaped member formed by extrusion molding. The longitudinal direction of the upper frame 4, the lower frame 5, and the crossbeam 7 is the left-right direction S, and the longitudinal direction of the vertical frame 6 is the up-down direction R.

[0015] The upper frame 4 and the lower frame 5 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 6 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 crossbeam 7 is a horizontal frame (middle horizontal frame) located in the middle of the frame body 3 in the up-down direction R, and extends in the horizontal direction. The crossbeam 7 is located between the upper frame 4 and the lower frame 5 and is connected to the pair of vertical frames 6. The ends of the upper frame 4, the lower frame 5, and the pair of vertical frames 6 are connected to each other, and both ends of the crossbeam 7 are connected to the pair of vertical frames 6, thereby framing the frames 4 to 6 and the crossbeam 7. The crossbeam 7 is installed on the pair of vertical frames 6 and divides the opening 3A of the frame body 3 into upper and lower sections. The panel 2A is fitted into the frame body 3, and is held by the frames 4 to 6 and the interlining 7 of the frame body 3, and is fixed to the frame body 3.

[0016] Fig. 4 is a cross-sectional view showing adjacent portions of two left and right curtain wall units 2 of the first embodiment, and shows an enlarged portion of Fig. 3. In Fig. 4, a portion of the gondola 20 is schematically shown by a two-dot chain line. As shown in the figure, a plurality of curtain wall units 2 and frames 3 are installed side by side in the left-right direction S on the exterior wall 11 of a building 10. The left and right curtain wall units 2 and frames 3 installed side by side in the left-right direction S are adjacent to each other in the left-right direction S. In the left and right curtain wall units 2 adjacent to each other in the left-right direction S, the vertical frame 6 of one curtain wall unit 2 and the vertical frame 6 of the other curtain wall unit 2 are arranged adjacent to each other on the left and right.

[0017] When the curtain wall units 2 are installed side by side on the building 10 (exterior wall 11), the left and right curtain wall units 2 adjacent in the left-right direction S form a joint M between the vertical frames 6 adjacent in the left-right direction S. The joint M is a gap space (joint space) located between the vertical frames 6 of the left and right curtain wall units 2. The joints M of the curtain wall units 2 arranged side by side in the up-down direction R are aligned with each other in the left-right direction S and the indoor-outdoor direction T, and are arranged side by side in the up-down direction R. The joint M is a vertical joint extending in the longitudinal direction of the vertical frame 6 and is formed along the vertical frame 6. The joint M is closed at a position between the adjacent vertical frames 6 at a position closer to the indoor side than the panel 2A, and is open toward the outdoor side of the curtain wall unit 2 at a position closer to the outdoor side than the panel 2A.

[0018] The vertical frames 6 of the left and right curtain wall units 2 are adjacent to each other in the left-right direction S with a joint M formed between them, and face each other with the joint M in between. The vertical frames 6 have a rail portion 6A that guides the gondola 20. The rail portion 6A is a groove-shaped guide portion (guide rail) that is provided on the joint M side of the vertical frames 6 and is open toward the joint M. The rail portion 6A is located on the indoor side of the panel 2A, faces the joint M, and extends in the longitudinal direction of the vertical frames 6. The rail portions 6A of vertical frames 6 adjacent in the left-right direction S face each other while being spaced apart in the left-right direction S. The rail portions 6A of the curtain wall units 2 lined up in the up-down direction R are aligned with each other in the left-right direction S and the indoor-outdoor direction T, and are arranged side by side in the up-down direction R.

[0019] The gondola 20 has a gondola body (not shown) that is located outside the curtain wall 1 and the curtain wall unit 2 and on which passengers board, and a guide body 21 that moves integrally with the gondola body. The gondola body, guide body 21, and gondola 20 move in the vertical direction R to ascend and descend. The guide body 21 is a part of the gondola 20 used to guide the ascending and descending of the gondola body, and connects the gondola body to the vertical frame 6 so that it can move in the vertical direction R. The guide body 21 also has a rod-shaped arm 22 that extends from the gondola body to the vertical frame 6, and multiple guide rollers 23 rotatably attached to the arm 22. The arm 22 and guide body 21 protrude from the gondola body toward the vertical frame 6 and extend to the joint M. The guide roller 23, arm 22, and guide body 21 are arranged in the joint M between the vertical frames 6 of the left and right curtain wall units 2.

[0020] The guide rollers 23 are arranged at the joints M on the inside of the rail portions 6A of the vertical frames 6 adjacent in the left-right direction S, and are in contact with the rail portions 6A. In this state, the guide rollers 23 and guide bodies 21 are guided by the rail portions 6A of the vertical frames 6. The curtain wall unit 2 and vertical frames 6 use the rail portions 6A to guide the guide rollers 23 and guide bodies 21 that move up and down. The guide rollers 23, guide bodies 21, and gondola 20 move up and down (move) while being guided by the rail portions 6A in the longitudinal direction (up-down direction R) of the rail portions 6A and vertical frames 6.

[0021] The curtain wall unit 2 and the frame body 3 include a vertical frame 6 that holds the panel 2A on the indoor side, and a batten 30 that holds the panel 2A on the outdoor side. The vertical frames 6 of the left and right curtain wall units 2 are spaced apart in the left-right direction S, and are adjacent to and face each other in the left-right direction S. In each curtain wall unit 2, the vertical frame 6 is located on the indoor side of the panel 2A, and the panel 2A is located on the outdoor side of the vertical frame 6. The batten 30 is a vertical batten that extends vertically and is located on the outdoor side of the vertical frame 6. The panel 2A (the vertical edge portion of the panel 2A) is located between the vertical frame 6 and the batten 30 in the indoor-outdoor direction T, and is held between the vertical frame 6 and the batten 30.

[0022] The vertical frame 6 has two frame sections 6B, 6C (first frame section 6B, second frame section 6C) connected to each other, and a heat insulating material 6D provided between the two frame sections 6B, 6C. The first frame section 6B is the main frame section of the vertical frame 6 and is connected to the upper frame section 4, the lower frame section 5, and the crossbeam 7. The second frame section 6C is an attached frame section attached to the first frame section 6B and is attached to the first frame section 6B via the heat insulating material 6D. The batten 30 is attached to the second frame section 6C and is held by the second frame section 6C.

[0023] The second frame portion 6C is disposed on the joint M side of the first frame portion 6B and is attached to the first frame portion 6B at a position closer to the indoor side than the panel 2A. The second frame portion 6C is attached to the first frame portion 6B at a position closer to the indoor side than the panel 2A, with a heat insulating material 6D interposed between the first frame portion 6B and the second frame portion 6B, and protrudes from the first frame portion 6B toward the outdoor side. The first frame portion 6B, the heat insulating material 6D, and the second frame portion 6C are overlapping and connected, and the heat insulating material 6D contacts the first frame portion 6B and the second frame portion 6C. The heat insulating material 6D ensures that the first frame portion 6B and the second frame portion 6C are spaced apart and do not contact each other throughout.

[0024] The heat insulating material 6D is an insulating material (here, insulating rubber, which is an elastic body) having a heat insulating function, and is disposed so that the entire second frame portion 6C is separated from the first frame portion 6B. The heat insulating material 6D is a solid heat insulating material, and is provided over the entire longitudinal direction of the vertical frame 6 or at multiple locations along the longitudinal direction of the vertical frame 6. Here, the heat insulating material 6D is provided over the entire longitudinal direction of the vertical frame 6 and is sandwiched between the first frame portion 6B and the second frame portion 6C. The heat insulating material 6D is also disposed in the location (gap) between the first frame portion 6B and the second frame portion 6C, between the opposing portions of the first frame portion 6B and the second frame portion 6C.

[0025] Each curtain wall unit 2 includes a weatherstripping member 40 and a protruding member 50 attached to a vertical frame 6 (here, the second frame portion 6C). The weatherstripping member 40 and the protruding member 50 are elastically deformable rubber members that extend in the longitudinal direction of the vertical frame 6 and are arranged along the vertical frame 6. The vertical frame 6 includes a rail portion 6A, a protruding wall portion 6E, an engaging portion 6F, and a connecting portion 6G, which are provided on the second frame portion 6C. The protruding wall portion 6E is connected to the rail portion 6A and protrudes from the rail portion 6A toward the exterior. The protruding wall portion 6E is located to the side of the panel 2A in the left-right direction S and is arranged along the indoor-outdoor direction T. The rail portions 6A and the protruding wall portions 6E of the vertical frames 6 of the left and right curtain wall units 2 form a joint M between them and face the joint M.

[0026] The batten 30 is attached to the protruding wall portion 6E of the vertical frame 6, and is arranged from the protruding wall portion 6E to the outdoor side of the panel 2A. The batten 30 also has a holding portion 31 that holds the panel 2A on the outdoor side, and an attachment piece 32 that protrudes from the holding portion 31 to the indoor side. The attachment piece 32 is located on the panel 2A side of the protruding wall portion 6E of the vertical frame 6, and is arranged along the indoor-outdoor direction T. The attachment piece 32 is engaged with the protruding wall portion 6E, and the attachment piece 32 and batten 30 are attached to the protruding wall portion 6E and the vertical frame 6.

[0027] The engagement portion 6F of the vertical frame 6 is a groove-shaped groove portion (engagement groove portion) located on the indoor side of the rail portion 6A. The engagement portion 6F opens toward the side of the vertical frame 6 and extends in the longitudinal direction of the vertical frame 6. The weatherstripping material 40 is fitted into the engagement portion 6F, engages with the engagement portion 6F, and is attached to the engagement portion 6F. The weatherstripping materials 40 of curtain wall units 2 adjacent in the left-right direction S are located on the indoor side of the joint M, are positioned opposite each other in the left-right direction S, and come into contact with each other. The weatherstripping material 40 seals the space between the vertical frames 6 of the curtain wall units 2 adjacent in the left-right direction S, and also seals the indoor side of the joint M. The weatherstripping material 40 seals the joint M at a position indoors relative to the rail portion 6A. The joint M is partitioned and closed by the weatherstripping material 40 at a position between the vertical frames 6.

[0028] The connecting portion 6G of the vertical frame 6 is a groove-shaped groove portion (connecting groove portion) that is located at the outdoor end of the vertical frame 6 (the protruding wall portion 6E of the second frame portion 6C) and is arranged facing the outdoor side. The connecting portion 6G is open toward the outdoor side of the vertical frame 6 and extends in the longitudinal direction of the vertical frame 6. The protruding member 50 is attached to the connecting portion 6G, connected to the connecting portion 6G, and protrudes from the vertical frame 6 toward the joint M. The protruding member 50 is a windbreak member (wind stopper member) that is located on the side of the vertical frame 6 (the joint M side) and is arranged in the joint M. The protruding member 50 is attached to the connecting portion 6G of one or both of the vertical frames 6 that are adjacent to each other in the left-right direction S across the joint M (the vertical frames 6 of the curtain wall units 2 that are installed side by side in the left-right direction S).

[0029] Here, the protruding members 50 are attached to and connected to the connecting portions 6G of both of the left and right vertical frames 6 that are adjacent in the left-right direction S with the joint M in between, and protrude in the left-right direction S from the connecting portions 6G (the outdoor-side ends of the vertical frames 6). When the curtain wall units 2 are installed side by side in the left-right direction S, the protruding members 50 of the left and right vertical frames 6 are positioned opposite each other in the left-right direction S and come into contact with each other at the joint M. The protruding members 50 divide the joint M in the indoor-outdoor direction T and close the joint M between the left and right vertical frames 6. The protruding members 50 block outside air from flowing from the outdoor side of the curtain wall unit 2 into the inside of the joint M (the portion of the joint M that is indoors relative to the protruding members 50), preventing outside air from flowing into the inside of the joint M.

[0030] The guide body 21 (arm 22) of the gondola 20 is arranged from the outdoor side of the protruding member 50 to the indoor side, and comes into contact with the protruding members 50 of the left and right vertical frames 6, elastically deforming the protruding members 50. When the gondola 20 is raised or lowered, the guide body 21 moves (raises or lowers) in the up-and-down direction R while contacting the protruding members 50 at the joint M. The rail portion 6A of the vertical frame 6 guides the guide body 21 (guide roller 23) of the gondola 20, which rises or lowers while contacting the protruding members 50 within the joint M. The gondola 20 and the gondola main body rise or lower along the curtain wall unit 2 on the outdoor side of the curtain wall unit 2, guided by the guide body 21 by the rail portion 6A.

[0031] The protruding member 50 has an attachment portion 51 that is located within the connecting portion 6G, which is a groove portion of the vertical frame 6, and is attached to the connecting portion 6G. The attachment portion 51 is located at the end (base end) of the protruding member 50 on the vertical frame 6 side, and extends in the longitudinal direction of the vertical frame 6. The attachment portion 51 is inserted into the concave connecting portion 6G from the outdoor side, and is positioned inside the connecting portion 6G and fitted into the connecting portion 6G. As a result, the attachment portion 51 is attached to and connected to the connecting portion 6G, and is held by the connecting portion 6G. Within the connecting portion 6G, the attachment portion 51 faces the internal space of the connecting portion 6G, with a gap between it and the inner surface of the connecting portion 6G.

[0032] FIG. 5 is a perspective view showing a protruding member 50 of the curtain wall unit 2 of the first embodiment, showing a portion of the protruding member 50 in the longitudinal direction. As shown in the figure, the protruding member 50 has a cutout 52 formed in the mounting portion 51. The cutout 52 is a void formed in a part of the mounting portion 51, and is formed by performing a notch process on the mounting portion 51. By performing the notch process, a part of the mounting portion 51 is cut out, and the cutout 52 is formed in that part of the mounting portion 51. The cutout 52 is formed at one or more locations in the longitudinal direction of the mounting portion 51. The longitudinal direction of the mounting portion 51 and the longitudinal direction of the protruding member 50 coincide with the longitudinal direction of the vertical frame 6.

[0033] Here, the mounting portion 51 is cut out and removed at two locations in the longitudinal direction of the mounting portion 51, thereby forming notches 52 in the two locations of the mounting portion 51. The notches 52 are also formed in two locations, at the top and bottom of the mounting portion 51. The notches 52 are formed between the upper mounting portion 51 located above the notches 52 and the lower mounting portion 51 located below the notches 52, and are positioned between the upper and lower mounting portions 51. The mounting portion 51 having the notches 52 is positioned within the connecting portion 6G of the vertical frame 6 and attached to the connecting portion 6G. Within the connecting portion 6G, the notches 52 face the internal space of the connecting portion 6G and are open toward the internal space of the connecting portion 6G.

[0034] Figure 6 is a cross-sectional view showing a portion including a connecting portion 6G between the protruding member 50 and the vertical frame 6 in the curtain wall unit 2 of the first embodiment, and shows an enlarged portion of Figure 4. Figure 7 is a vertical cross-sectional view showing a portion including a connecting portion 6G between the protruding member 50 and the vertical frame 6 in the curtain wall unit 2 of the first embodiment, showing the curtain wall unit 2 cut along line X3-X3 in Figure 6.

[0035] As shown in the figure, the curtain wall unit 2 includes a restricting member 60 that restricts movement of the protruding member 50. The restricting member 60 is located in the notch 52 of the protruding member 50 and restricts movement of the mounting portion 51 and the protruding member 50 in the vertical direction R. In this example, the restricting member 60 is a sealant 61 that is filled into the connecting portion 6G, which is a groove portion of the vertical frame 6, and the notch 52 of the protruding member 50. The sealant 61 is filled into the notch 52 and the areas above and below the notch 52 (the areas surrounding the notch 52) inside the connecting portion 6G (groove), and also fills the notch 52 and hardens within the connecting portion 6G and the notch 52. The hardened sealant 61 adheres to the inner surface of the connecting portion 6G, the notch 52, and the mounting portion 51, and adheres to the inner surface of the connecting portion 6G, the notch 52, and the mounting portion 51. As a result, the sealing material 61 holds the notched portion 52 and the mounting portion 51 of the protruding member 50 while being held by the connecting portion 6G.

[0036] The restricting member 60 is disposed at the notch 52 of the protruding member 50 within the connecting portion 6G of the vertical frame 6, and is positioned inside the notch 52. Furthermore, the restricting member 60 contacts the mounting portion 51 of the protruding member 50 within the notch 52, and holds down the mounting portion 51 in both the up-down direction R. Within the connecting portion 6G, the restricting member 60 contacts the upper portion of the notch 52 in the mounting portion 51 (the mounting portion 51 above the notch 52) and the lower portion of the notch 52 (the mounting portion 51 below the notch 52), and holds down the mounting portions 51 above and below the notch 52, stopping the mounting portion 51 and the protruding member 50. The upper and lower mounting portions 51 are caught by the restricting member 60 within the notch 52 in the up-down direction R, are received by the restricting member 60, and are locked by the restricting member 60.

[0037] When the protruding member 50 moves upward, the restricting member 60 presses the mounting portion 51 below the cutout portion 52, stopping the upward movement of the mounting portion 51 and restricting the upward movement of the mounting portion 51 and the protruding member 50. When the protruding member 50 moves downward, the restricting member 60 presses the mounting portion 51 above the cutout portion 52, stopping the downward movement of the mounting portion 51 and restricting the downward movement of the mounting portion 51 and the protruding member 50. The restricting member 60 restricts the movement of the mounting portion 51 in the up-down direction R within the connecting portion 6G, and also restricts the movement of the mounting portion 51 and the protruding member 50 in the up-down direction R along the connecting portion 6G. This maintains the position of the protruding member 50 at the attached position to the vertical frame 6.

[0038] As described above, in the curtain wall unit 2 of the first embodiment, the regulating material 60 can prevent the protruding material 50 from moving in the vertical direction R and shifting the position of the protruding material 50 in the vertical direction R. Furthermore, even if the guide body 21 of the gondola 20 that comes into contact with the protruding material 50 moves up and down, the protruding material 50 can be prevented from moving in the vertical direction R, preventing the position of the protruding material 50 from shifting in the vertical direction R. The regulating material 60, which is a sealing material 61, can easily regulate the movement of the protruding material 50 in the vertical direction R. The protruding material 50 can also prevent outside air from flowing into the joint M, thereby preventing the vertical frame 6 from being cooled by the outside air.

[0039] The vertical frame 6 may not have a rail portion 6A. In this case, the vertical frame 6 does not guide the guide body 21 of the gondola 20, and the guide body 21 of the gondola 20 is not disposed in the joint M. The vertical frame 6 may also be a vertical frame (for example, a vertical frame made of a single frame material) that does not have the first frame portion 6B, the second frame portion 6C, and the insulating material 6D. The protruding member 50 may be attached to only the connecting portion 6G of one of the vertical frames 6 adjacent to each other in the left-right direction S across the joint M. The connecting portion 6G of the vertical frame 6 is not limited to a groove portion and may be, for example, a protrusion. In this case, the mounting portion 51 of the protruding member 50 is a recess that is attached to and connected to the connecting portion 6G, which is a protrusion. The present invention is not limited to a curtain wall unit 2 having a fixed panel 2A, but can also be applied to various curtain wall units (for example, a curtain wall unit having an openable / closable or movable panel).

[0040] (Second embodiment) Next, a curtain wall unit 2 of a second embodiment will be described. With regard to the curtain wall unit 2 of the second embodiment, explanations of the same matters as those in the curtain wall unit 2 of the first embodiment will be omitted, and the following will mainly describe matters that differ from the curtain wall unit 2 of the first embodiment. Furthermore, with regard to the curtain wall unit 2 of the second embodiment, the same names and symbols as those in the curtain wall unit 2 of the first embodiment will be used for components that correspond to those in the curtain wall unit 2 of the first embodiment.

[0041] Fig. 8 is a cross-sectional view showing a portion including a connecting portion 6G between the protruding member 50 and the vertical frame 6 in the curtain wall unit 2 of the second embodiment, and similar to Fig. 6, shows an enlarged portion of the curtain wall unit 2. Figs. 9 and 10 are longitudinal cross-sectional views showing a portion including a connecting portion 6G between the protruding member 50 and the vertical frame 6 in the curtain wall unit 2 of the second embodiment, showing the curtain wall unit 2 cut along the X4-X4 line in Fig. 8. Fig. 9 shows a state in which the restricting member 60 is arranged in the cutout portion 52 of the protruding member 50, and Fig. 10 shows a state in which the protruding member 50 has moved downward relative to the protruding member 50 shown in Fig. 9.

[0042] As shown in the figure, the restricting member 60 is a restricting part 62 fixed to the vertical frame 6 and disposed in the notch 52 of the protruding member 50. The restricting part 62 is a part made of metal or synthetic resin, and is fixed to the vertical frame 6 outside the connecting part 6G of the vertical frame 6 by a fastener 63, which is a screw. The connecting part 6G, which is a groove in the vertical frame 6, has an insertion part 6H through which the restricting part 62 is inserted. The insertion part 6H is a through-hole formed by cutting out a part of the connecting part 6G, and penetrates the indoor side of the connecting part 6G in the indoor-outdoor direction T, opening the interior (internal space) of the connecting part 6G toward the indoor side. The insertion part 6H is located on the indoor side of the notch 52 and adjacent to the notch 52. The restricting part 62 is disposed from the outside (indoor side) of the connecting part 6G through the insertion part 6H to the interior of the connecting part 6G.

[0043] The restricting part 62 is fixed to the vertical frame 6 on the indoor side of the connecting part 6G and the insertion part 6H, and is arranged outside the connecting part 6G (the indoor side of the connecting part 6G) and inside the connecting part 6G (groove part) with the insertion part 6H inserted. Within the connecting part 6G of the vertical frame 6, the restricting part 62 is arranged in the cutout part 52 of the protruding member 50, and receives and holds the mounting part 51 of the protruding member 50. The restricting part 62 is located on the opposite side of the joint M (the panel 2A side) with respect to the vertical frame 6 (here, the protruding wall part 6E), and is arranged between the vertical frame 6 and the batten 30 (here, the mounting piece 32) in the left-right direction S. The restricting part 62 is covered by the vertical frame 6 located on the joint M side.

[0044] The regulating part 62 has a fixing part 64 fixed to the vertical frame 6, and a receiving part 65 that is disposed in the notch 52 of the protruding member 50 within the connecting part 6G of the vertical frame 6 and receives the mounting part 51 of the protruding member 50. The fixing part 64 is the indoor side part of the regulating part 62, is located outside the connecting part 6G of the vertical frame 6, and is fixed to the vertical frame 6 by a fixing device 63. The fixing part 64 is located on the indoor side of the connecting part 6G and the insertion part 6H, and is disposed between the vertical frame 6 (projecting wall part 6E) and the batten 30 (mounting piece 32) in the left-right direction S, and is fixed to the projecting wall part 6E of the vertical frame 6. The part of the regulating part 62 between the fixing part 64 and the receiving part 65 is inserted through the insertion part 6H of the connecting part 6G.

[0045] The receiving portion 65 of the regulating part 62 is the outdoor end of the regulating part 62, and is disposed within the connecting portion 6G of the vertical frame 6. Within the connecting portion 6G, the receiving portion 65 is disposed in the cutout portion 52 of the protruding member 50 and is located inside the cutout portion 52. When the protruding member 50 moves in the up-down direction R, the receiving portion 65 comes into contact with the mounting portion 51 of the protruding member 50 within the cutout portion 52 and receives the mounting portion 51. As a result, the receiving portion 65 presses the mounting portion 51 in both the up-down direction R, holds the mounting portion 51, and regulates movement of the mounting portion 51 in the up-down direction R within the connecting portion 6G.

[0046] Within the connecting portion 6G of the vertical frame 6, the receiving portions 65 come into contact with the mounting portions 51 above the cutout portions 52 and the mounting portions 51 below the cutout portions 52, pressing down on the upper and lower mounting portions 51 of the cutout portions 52 and stopping the mounting portions 51 and the protruding members 50. The upper and lower mounting portions 51 are caught by the receiving portions 65 within the cutout portions 52 in the vertical direction R, are received by the receiving portions 65, and are locked by the receiving portions 65. The receiving portions 65 and the restricting parts 62 restrict the mounting portions 51 and the protruding members 50 from moving in the vertical direction R along the connecting portion 6G.

[0047] A sealant (not shown) is filled into the inside of the connecting portion 6G, which is a groove, at one or more locations (here, two locations, at the top and bottom of the protruding member 50) in the longitudinal direction (vertical direction R) of the protruding member 50. The hardened sealant adheres to the inner surface of the connecting portion 6G and the mounting portion 51 of the protruding member 50, and adheres to the inner surface of the connecting portion 6G and the mounting portion 51. As a result, the sealant holds the mounting portion 51 of the protruding member 50 while being held by the connecting portion 6G.

[0048] In the curtain wall unit 2 of the second embodiment, the restricting part 62 fixed to the vertical frame 6 can stably restrict movement of the protruding member 50 in the up-down direction R. By fixing the restricting part 62 to the vertical frame 6, even if the restricting part 62 is pushed in the up-down direction R by the mounting part 51 of the protruding member 50, the restricting part 62 is reliably prevented from coming off the vertical frame 6. As a result, the restricting part 62 can be reliably held in the vertical frame 6. Furthermore, the fixing part 64 of the restricting part 62 can be easily fixed to the vertical frame 6 outside the connecting part 6G of the vertical frame 6, and the receiving part 65 of the restricting part 62 can stably restrict movement of the mounting part 51 of the protruding member 50 in the up-down direction R inside the connecting part 6G of the vertical frame 6.
