Description

[Technical Field]

[0001] The present invention relates to a connecting structure of battens that connects battens to each other, and to a curtain wall unit equipped with a connecting structure of battens. [Background technology]

[0002] In a curtain wall unit equipped with vertical ribs and interlocking bars, the vertical ribs extend vertically between the left and right vertical frames and span the upper and lower frames. Interlocking bars are arranged side by side on either side of the vertical rib, extend horizontally, and span between the vertical rib and the vertical frames on both sides of the vertical rib. Conventionally, a curtain wall unit equipped with left and right ribs that are vertical ribs and left and right intermediate frames that are interlocking bars has been known as such a curtain wall unit (see Patent Document 1).

[0003] In the conventional curtain wall unit described in Patent Document 1, left and right panels are arranged on either side of a left and right rib, and a batten for the intermediate frame, which is a batten, is attached to each of the left and right intermediate frames. The left and right panels are respectively positioned between the intermediate frame and the batten and held between the intermediate frame and the batten. However, in the connection structure of the batten for such a curtain wall unit, from the standpoint of design, it is sometimes required to connect one batten to multiple battens and hold the panels with one batten. In contrast, with conventional curtain wall units, if the positions of the left and right intermediate frames are misaligned vertically due to assembly errors, for example, it may be difficult to attach one batten to the left and right intermediate frames. This raises concerns about increased effort required for batten installation. [Prior art documents] [Patent documents]

[0041] The first panel 2A (lower edge 2C) and the second panel 2B (upper edge 2D) are positioned between two interlinings 9 (retaining portions 9C, 9D) and one interlining batten 30 (retaining pieces 31, 32) in the thickness direction of the panels 2A, 2B, and are held between the two interlinings 9 and the one interlining batten 30. In addition, the first panel 2A is positioned above the protruding portion 23 of the connecting material 20, between the first retaining portions 9C of the two interlinings 9 and the first retaining piece 31 of the one interlining batten 30, and is held between the first retaining portions 9C of the two interlinings 9 and the first retaining piece 31 of the one interlining batten 30. The second panel 2B is positioned below the protruding portion 23 of the connecting material 20, between the second retaining portions 9D of the two interlinings 9 and the second retaining piece 32 of one interlining ridge 30, and is held between the second retaining portions 9D of the two interlinings 9 and the second retaining piece 32 of one interlining ridge 30.

[0042] The protruding piece 33 of the batten 30 is located on the batten 9 side of the holding pieces 31, 32 and is arranged along the thickness direction T of the curtain wall unit 2. The protruding piece 33 protrudes from the holding pieces 31, 32 in the thickness direction T of the curtain wall unit 2, and also protrudes from the holding pieces 31, 32 to a position between the upper and lower panels 2A, 2B. The protruding piece 33 and the batten 30 are spaced apart from the first panel 2A (lower edge portion 2C) and the second panel 2B (upper edge portion 2D) in the vertical direction R, and are arranged between the first panel 2A and the second panel 2B, below the first panel 2A, and above the second panel 2B. The protruding piece 33 is also located below the protruding portion 23 of the connecting material 20.

[0043] The batten 30 is attached to and held by the two attachment projections 34 on the two attachment receiving portions 24, the protruding portion 23, and the connecting member 20. The attachment projections 34 are hook portions bent toward the opposite side of the batten 9 and are spaced apart in the thickness direction T of the curtain wall unit 2. The attachment projections 34 are located above the projection 33, protrude upward from the projection 33, and are disposed between the first panel 2A and the second panel 2B. The two attachment projections 34 of the batten 30 are each hooked onto the attachment receiving portions 24 of the connecting member 20 from the batten 9 side, received in the attachment receiving portions 24, and engaged with the attachment receiving portions 24. The projections 34 and the batten 30 are attached to the extension portion 23 and the connecting member 20 between the first panel 2A and the second panel 2B by engaging the attachment projections 34 with the attachment receiving portions 24.

[0044] In the connecting structure of the battens 30 and the curtain wall unit 2 described above, one batten 30 can be easily connected to two battens 9 via one connector 20. Furthermore, even if the positions of the two battens 9 are misaligned vertically due to assembly errors or the like, the connector 20 can connect the batten 30 to the two battens 9. In this way, by making it possible to connect one batten 30 to two battens 9, the connecting structure of the batten 30 and the design of the curtain wall unit 2 can be improved. The work of connecting the batten 30 to two battens 9 can also be simplified, improving the workability of the connecting work.

[0045] The connecting members 20 attached to the two interlocking members 9 and the support members 40 placed on the connecting members 20 suppress unevenness in the load received from the first panel 2A, thereby stably supporting the first panel 2A. The connecting members 20 and the support members 40 also allow the load of the first panel 2A to be received evenly on each side of the two interlocking members 9. Furthermore, the connecting portions 21 and fixing portions 22 of the connecting members 20 allow the connecting members 20 to be stably attached to the two interlocking members 9.

[0046] In this embodiment, an example in which the batten 30 is connected to two battens 9 by the connector 20 has been described. However, the batten 30 may also be connected to three or more battens 9 by the connector 20. In this case, the battens 9 are arranged side by side with multiple vertical ribs 8 in between, and the connector 20 is attached to the battens 9 across the multiple vertical ribs 8. Furthermore, the present invention is not limited to curtain wall units 2 having only fixed panels 2A, 2B, but can also be applied to various curtain wall units (for example, curtain wall units including openable or movable panels). The batten connection structure of the present invention is not limited to curtain wall units, but can also be applied to the batten connection structure of various structures having batten ribs connected to each other without battens.
