The curtain wall 1 is arranged on the outdoor side of the framework 12 of the building 10, and forms the wall surface (exterior wall surface) of a wall portion 11 of the building 10.

[0011] When the curtain wall 1 installed on the building 10 is viewed from the front (see FIG. 1), the direction that is up and down is the up-down direction, and the direction that is left and right is the left-right direction. In FIG. 1, the up-down direction is the vertical direction, and the left-right direction is the horizontal direction. The indoor / outdoor direction is the indoor / outdoor direction (indoor / outdoor direction) in the curtain wall 1 installed on the building 10. Also, the indoor / outdoor direction is the front-to-back direction (depth direction) when the curtain wall 1 installed on the building 10 is viewed from the front, and in FIG. 1, it is the horizontal direction that intersects with the left-to-right direction. In this way, the directions related to the curtain wall 1 are specified by the directions when it is installed on the building 10. Also, the indoor side and the outdoor side of the curtain wall 1 are the indoor side and the outdoor side when it is installed on the building 10.

[0012] The mullions 2 are vertical members extending in the up-down direction (vertical direction) and are arranged at intervals in the left-right direction. The multiple mullions 2 are arranged in a row from left to right, spaced apart from one another in the left-right direction, on the wall portion 11 of the building 10. The mullions 3 are horizontal members extending in the left-right direction (horizontal direction) and are arranged between adjacent mullions 2 on the left and right, spanning the left and right mullions 2. Between adjacent mullions 2 on the left and right, the mullions 3 are arranged at intervals in the up-down direction and attached to the left and right mullions 2. The multiple mullions 3 are also arranged in a row from up to down, spaced apart from one another in the up-down direction.

[0013] The multiple mullions 2 and multiple crossbeams 3 are combined in a lattice (frame) shape to form multiple square openings 4. The multiple openings 4 are formed lined up in the left-right direction with the mullions 2 sandwiched between them, and are also formed lined up in the up-down direction with the crossbeams 3 sandwiched between them. Each opening 4 is formed by adjacent mullions 2 on the left and right and adjacent transoms 3 on the top and bottom. The panel body 5 is a rectangular panel-like member, and is disposed in each opening 4. Here, the panel body 5 is a glass panel body (for example, plate glass, double glazing, or laminated glass), and is fixed to the opening 4 to close it.

[0014] The openings 4 are formed on both the left and right sides of the mullion 2 in the left-right direction, and on both the top and bottom sides of the crosspiece 3 in the up-down direction.

At a location between the partition member 80 and the groove bottom portion 71 of the groove portion 70, the projections 82 and 84 of the partition member 80 abut against the groove bottom portion 71 of the groove portion 70, and the projections 78 and 79 of the groove bottom portion 71 of the groove portion 70 abut against the partition member 80. As a result, a gap is formed between the partition member 80 and the groove bottom portion 71 of the groove portion 70. The projection 79 of the groove bottom portion 71 of the groove portion 70 is an engaging portion (engaging projection) and engages with the engaged portion 87 of the partition member 80.

[0038] The groove portion 70 and the partition member 80 shown in FIG. 8 form a filling portion 7B in which a sealing material 6B is filled at a location on the second storage groove portion 60 side in the groove portion 70. The filling portion 7B is formed between the partition member 80 and the groove portion 70 (here, between the protrusion 82 of the partition member 80 and the protrusion 75 of the groove portion 70, which face each other in the projection direction R of the mullion 2). The filling portion 7B is formed at a location adjacent to the second storage groove portion 60 between the partition member 80 and the groove portion 70, and the groove bottom portion 71 of the groove portion 70 is located at the bottom of the groove-shaped filling portion 7B. A backup material 8B is provided on the groove bottom portion 71 side in the filling portion 7B. The sealing material 6B is received by the backup material 8B, filled into the filling portion 7B, and comes into close contact with the protrusion 82 of the partition member 80 and the protrusion 75 of the groove portion 70.

[0039] 8 are located between the location between the partition member 80 and the groove bottom 71 of the groove portion 70 and the second accommodating groove portion 60, and extend in the longitudinal direction of the partition member 80. The sealing material 6B blocks and seals the location between the protrusion 82 of the partition member 80 and the protrusion 75 of the groove portion 70. The sealing material 6B stops water from flowing from the second accommodating groove portion 60 to the location between the protrusion 82 of the partition member 80 and the protrusion 75 of the groove portion 70, and prevents water from entering the location between the partition member 80 and the groove bottom 71 of the groove portion 70.

[0040] The partition member 90 shown in FIG. 7 is a partition member (second partition member) different from the partition member 80 shown in FIG. 6 and FIG. 8. The partition member 90 is a divided partition member divided in the projection direction R of the mullion 2, and the width of each partition member 90 in the projection direction R of the mullion 2 is narrower than the width of the partition member 80 in the projection direction R of the mullion 2. Two identical partition members 90 are arranged at an indoor side part and an outdoor side part inside the groove portion 70, spaced apart from each other in the projection direction R of the mullion 2. In the groove portion 70, the partition member 90 extends in the longitudinal direction of the mullion 2 (the longitudinal direction of the groove portion 70) along the groove portion 70. The second storage groove portion 60 shown in FIG. 7 is partitioned by the two partition members 90 in the middle part inside the groove portion 70 in the projection direction R of the mullion 2, and is formed between the two partition members 90 in the groove portion 70. The partition members 90 are positioned within the recessed groove portion 70 on both the outdoor side and indoor side of the second accommodating groove portion 60, and are also positioned between the indoor side hollow portion 20 and the second accommodating groove portion 60, and between the second hollow portion 42 and the second accommodating groove portion 60.

[0041] At the indoor side portion of the second accommodating groove portion 60 in the groove portion 70 shown in FIG. 7, a protrusion 91 protruding to the indoor side of the partition member 90 abuts against the indoor side groove wall portion 73 of the groove portion 70, and a protrusion 74 protruding to the outdoor side of the indoor side groove wall portion 73 of the groove portion 70 abuts against the partition member 90. In addition, at a location between the partition member 90 and the groove bottom portion 71 of the groove portion 70, a protrusion 92 of the partition member 90 abuts against the groove bottom portion 71 of the groove portion 70, and a protrusion 76 of the groove bottom portion 71 of the groove portion 70 abuts against the partition member 90. As a result, a gap is formed at a location between the partition member 90 and the groove bottom portion 71 of the groove portion 70. The protrusion 76 of the groove bottom portion 71 of the groove portion 70 is an engaging portion (engaging protrusion) and engages with an engaged portion 93 of the partition member 90.

[0042] In the portion of the recessed groove 70 on the indoor side of the second storage groove 60 shown in FIG. 7, the recessed groove 70 and the partitioning member 90 form a filling portion 7C in which a sealing material 6C is filled at a portion of the recessed groove 70 on the side of the second storage groove 60. The filling portion 7C is formed between the partitioning member 90 and the recessed groove 70 (here, the groove bottom 71 of the recessed groove 70). The filling portion 7C is formed at a portion adjacent to the second storage groove 60 between the partitioning member 90 and the groove bottom 71 of the recessed groove 70, and is located on the second storage groove 60 side (outside the room) of the protrusion 94 of the partitioning member 90. A backup material 8C is provided on the protrusion 94 side in the filling portion 7C. The sealing material 6C is received by the backup material 8C, filled into the filling portion 7C, and comes into close contact with the partitioning member 90 and the groove bottom 71 of the recessed groove 70.

[0043] The filling portion 7C and the sealing material 6C are located between the second accommodating groove portion 60 and the portion between the partition member 90 and the groove bottom 71 of the groove portion 70, and extend in the longitudinal direction of the partition member 90. The sealing material 6C closes and seals the portion between the partition member 90 and the groove bottom 71 of the groove portion 70. The sealing material 6C stops water from flowing from the second accommodating groove portion 60 to the portion between the partition member 90 and the groove bottom 71 of the groove portion 70, and prevents water from entering the portion between the partition member 90 and the groove bottom 71 of the groove portion 70.

[0044] 7 , in the outdoor portion of the second accommodating groove portion 60 in the groove portion 70, the projections 95, 96 projecting toward the outdoor side of the partition member 90 abut against the outdoor side groove wall portion 72 of the groove portion 70, and the projection 77 projecting toward the indoor side of the outdoor side groove wall portion 72 of the groove portion 70 abuts against the partition member 90. In the area between the partition member 90 and the groove bottom portion 71 of the groove portion 70, the projections 92, 94 of the partition member 90 abut against the groove bottom portion 71 of the groove portion 70, and the projection 78 of the groove bottom portion 71 of the groove portion 70 abuts against the partition member 90. As a result, a gap is formed between the partition member 90 and the groove bottom portion 71 of the groove portion 70.

[0045] In the portion of the second storage groove portion 60 on the outdoor side in the groove portion 70 shown in FIG. 7, the groove portion 70 and the partitioning member 90 form a filling portion 7D in which the sealing material 6D is filled at a portion of the groove portion 70 on the second storage groove portion 60 side. The filling portion 7D is formed between the partitioning member 90 and the groove portion 70 (here, between the protrusion 92 of the partitioning member 90 and the protrusion 79 of the groove portion 70, which face each other in the projection direction R of the mullion 2). The filling portion 7D is formed at a portion adjacent to the second storage groove portion 60 between the partitioning member 90 and the groove portion 70, and the groove bottom portion 71 of the groove portion 70 is located at the bottom of the groove-shaped filling portion 7D. A backup material 8D is provided on the groove bottom portion 71 side in the filling portion 7D. The sealing material 6D is received by the backup material 8D and filled into the filling portion 7D, and is in close contact with the protrusion 92 of the partitioning member 90 and the protrusion 79 of the groove portion 70.

[0046] The filling portion 7D and the sealing material 6D are located between the second accommodating groove portion 60 and the location between the partition member 90 and the groove bottom portion 71 of the groove portion 70, and extend in the longitudinal direction of the partition member 90. The sealing material 6D blocks and seals the location between the protrusion 92 of the partition member 90 and the protrusion 79 of the groove portion 70. The sealing material 6D stops water from flowing from the second accommodating groove portion 60 to the location between the protrusion 92 of the partition member 90 and the protrusion 79 of the groove portion 70, and prevents water from entering the location between the partition member 90 and the groove bottom portion 71 of the groove portion 70.

[0047] In the curtain wall 1 described above, the position of the second storage groove portion 60 of the second side portion 40 in the projection direction R of the mullion 2 can be easily changed by changing the partition members 80, 90 arranged in the recessed groove portion 70. Therefore, the uneven wall surface of the building 10 can be easily formed by using a common mullion 2. In addition, the uneven shape of the wall surface of the building 10 can be easily deformed.

[0048] The first storage groove 50 on the first side 30 of the mullion 2 and the second storage groove 60 on the second side 40 are located at different positions in the projection direction R of the mullion 2. This makes it easy to form the wall surface of the building 10 into an uneven shape. The sealing materials 6A, 6B, 6C, and 6D filled in the filling sections 7A, 7B, 7C, and 7D ensure the watertightness of the second storage groove 60 partitioned within the concave groove 70 of the mullion 2.

[0049] The groove portion 70 and the partition members 80, 90 are provided only on the second side portion 40 of the upright 2. The groove portion 70 and the partition members 80, 90 allow the position of the second storage groove portion 60 of the second side portion 40 to be changed to the projection direction R of the upright 2, making it easy to form an uneven wall surface of the building 10. In addition, the second end portion 3B of the transom 3 and the second vertical edge portion 5B of the panel body 5 accommodated in the second storage groove portion 60 of the second side portion 40 can be positioned based on the positions of the first end portion 3A of the transom 3 and the first vertical edge portion 5A of the panel body 5 accommodated in the first storage groove portion 50 of the first side portion 30.

[0050] The groove 70 and the partition members 80, 90 may be provided only on the first side 30 of the mullion 2, not on the second side 40 of the mullion 2. Alternatively, the groove 70 and the partition members 80, 90 may be provided on both the first side 30 and the second side 40 of the mullion 2, and the positions of both the first storage groove 50 of the first side 30 and the second storage groove 60 of the second side 40 may be changed to the projection direction R of the mullion 2. One or both of the partition members 80, 90 may be divided into multiple parts in the projection direction R of the mullion 2, and three or more partition members 80, 90 may be arranged in the groove 70. Sash windows may be installed in some locations of the multiple panel bodies 5 of the curtain wall 1. In this case, the sash frames of the sash windows are arranged between the mullions 2 adjacent to each other on the left and right, and are attached to the left and right mullions 2.

[0051] As described above, the curtain wall is a curtain wall including a plurality of uprights, a plurality of stringers spanning the uprights adjacent to each other on the left and right, openings formed on both the left and right sides of the uprights by the uprights and the stringers, and a panel body disposed in the opening, The upright has side portions located on both the left and right sides, and a receiving groove portion provided on both side portions to receive the end of the panel and the vertical edge portion of the panel body, At least one of the side portions on both sides of the upright is a curtain wall having a groove portion which is wider in the projected direction of the upright than the accommodating groove portion, and a partition member which is positioned within the groove portion and partitions the accommodating groove portion within the groove portion. Therefore, by using a curtain wall in which panels are placed in openings formed by mullions and stringers, it is possible to easily form uneven wall surfaces of a building.

[0052] The accommodating groove portion provided on one of the side portions on both sides of the upright and the accommodating groove portion provided on the other side are positioned at different positions in the projection direction of the upright. Therefore, the wall surface of a building can be easily formed into an uneven shape.

[0053] The groove portion and the partition member are provided on only one of the side portions on both sides of the upright. Therefore, by changing the position of the storage groove portion provided on either side of the mullion, it is possible to easily form an uneven wall surface of the building.

[0054] The groove portion and the partition member form a filling portion in a portion of the groove portion on the side of the accommodating groove portion, the filling portion being filled with a sealing material that seals the portion between the groove portion and the partition member. Therefore, the waterproofing of the storage groove portion defined within the recessed groove portion can be ensured. [Explanation of symbols]
