Description

[Technical Field]

[0001] The present invention relates to a curtain wall unit having a ventilation door and a duct connector, and a curtain wall having the curtain wall unit. [Background technology]

[0002] Curtain wall units are used in the curtain wall of a building and are installed side by side on the wall of the building. In addition to the window portion of the curtain wall unit, ventilation doors may be installed in the curtain wall unit. By opening the ventilation doors, air flows between the inside and outside of the building, ventilating the inside of the building. In contrast to this, window structures equipped with ducts used for exhaust or intake of air for air conditioning, etc., are also known in the past (see Patent Document 1).

[0003] In the conventional window structure described in Patent Document 1, a duct is connected to the upper portion of a window section, and a louver is provided on the outdoor side of the duct. When such a window section and duct are installed in a curtain wall unit, a duct connector is installed above the window section of the curtain wall unit, and the duct is connected to the duct connector. However, if a duct connector above the window section is installed in addition to a ventilation door in the curtain wall unit, the window section, the ventilation door section, and the duct connector section are installed in different locations on the curtain wall unit, resulting in different visual appearances. Therefore, curtain wall units equipped with such ventilation doors and duct connectors have room for improvement in terms of design when viewed from the outdoor side.

[0041] The duct connector 7 is a ventilating member for indoor equipment (not shown) and is open to the outdoors and the covering body 40. In this example, the duct connector 7 is a chamber box that is open to the outdoors. On the indoor side of the duct connector 7, a duct 15 of the building 10 is connected to the indoor equipment and the duct connector 7. The duct connector 7 is connected to the indoor equipment via the duct 15, and ventilates between the indoor equipment and the outdoors. For example, for air conditioning or ventilation, air passes through the duct connector 7, and the duct connector 7 performs at least one of intake and exhaust (air intake and exhaust). The indoor equipment is installed inside the building 10, and at least one of intake and exhaust is performed via the duct connector 7 and the duct 15.

[0042] Duct 15 is attached to duct connector 7 and extends from duct connector 7 toward the interior of the room. Duct 15 is a conduit that serves as an air passageway, extending from duct connector 7 to the indoor equipment. Duct 15 is installed between duct connector 7 and the indoor equipment to guide the air. The indoor equipment is, for example, an air conditioning equipment or a ventilation equipment. Air (outside air) is taken in from the outdoors by duct connector 7, flows from duct connector 7 through duct 15 to the indoor equipment, and is taken into the indoor equipment. Air also flows from the indoor equipment through duct 15 to duct connector 7, and is discharged outdoors by duct connector 7.

[0043] The ventilation door 6 is disposed at the ventilation opening 2C of the curtain wall unit 2 (ventilation section 5) and is used to ventilate the indoor section of the curtain wall unit 2. The ventilation opening 2C is the indoor section of the opening 5A of the ventilation section 5 of the curtain wall unit 2 (here, the part of the opening 5A located in the vision section 2B), and is located on the indoor side of the covering body 40. When the ventilation door 6 is opened, the ventilation opening 2C is opened, and the indoor section of the ventilation door 6 (the indoor space 14) communicates with the outdoors via the ventilation opening 2C. When the ventilation door 6 is closed, the ventilation opening 2C is closed by the ventilation door 6, and the indoor section of the ventilation door 6 is isolated from the outdoors by the ventilation door 6.

[0044] The outside air is air on the outdoor side of the curtain wall unit 2. When the ventilation door 6 is open, the outside air flows from the outdoor side of the curtain wall unit 2 through the ventilation opening 2C in the indoor-outdoor direction S. At that time, the outside air flows from the outdoor side of the ventilation opening 2C through the ventilation opening 2C toward the indoor side and flows into the indoor side of the ventilation door 6. Also, the indoor air flows from the indoor side of the ventilation door 6 through the ventilation opening 2C toward the outdoor side and flows out through the ventilation opening 2C and the outdoor side of the curtain wall unit 2. When the ventilation door 6 is closed, the ventilation door 6 closes the ventilation opening 2C, blocking the air flow.

[0045] The covering body 40 is a louver and has a plurality of louver blades 41 and a plurality of air passages 42 defined by the plurality of louver blades 41.

The plurality of air passages 42 are defined between adjacent louver blades 41 in the left-right direction, penetrate the covering body 40 in the indoor-outdoor direction S, and are open toward the outdoor side and the indoor side of the covering body 40. The covering body 40, the louver blades 41, and the air passages 42 are provided across the spandrel section 2A and the vision section 2B of the ventilation section 5 and extend in the vertical direction. The covering body 40 provides ventilation between the outdoor side and the indoor side of the covering body 40 through the air passages 42 between the louver blades 41.

[0046] The ventilation door 6, the duct connector 7, and the second closure panel body 33 are located on the indoor side of a common covering body 40, and are covered on the outdoor side by the common covering body 40. The covering body 40 is arranged over the outdoor sides of the ventilation door 6, the duct connector 7, and the second closure panel body 33, and entirely covers the ventilation door 6, the duct connector 7, and the second closure panel body 33. The single covering body 40, which is a louver, and the multiple louver blades 41 of the covering body 40 entirely cover the ventilation door 6, the duct connector 7, and the second closure panel body 33 in the vertical direction.

[0047] In each curtain wall unit 2, the frame body 3 and the covering body 40 are adjacent to each other, and the frame body 3 has a portion adjacent to the covering body 40. The outdoor side surface 43 of the covering body 40 is flush with the outdoor-facing visible surface 3A of the portion of the frame body 3 adjacent to the covering body 40. Here, the portion of the frame body 3 adjacent to the covering body 40 is the vertical middle frame 24 adjacent to the covering body 40 in the left-right direction, and the outdoor-facing visible surface 3A of the frame body 3 is the outdoor-facing visible surface of the vertical middle frame 24. Furthermore, the outdoor-facing visible surface of the vertical middle frame 24 is the outdoor-facing visible surface of the retaining portion 28 (batten 29) of the vertical middle frame 24. The outdoor side surface 43 of the covering body 40 is the surface of the covering body 40 located on the outdoor side, and in this case, it is the outdoor side surface of the multiple louver blades 41.

[0048] In two curtain wall units 2 adjacent to each other in the left-right direction, the covering body 40 of one curtain wall unit 2 and the frame body 3 of the other curtain wall unit 2 are adjacent to each other. Therefore, the frame body 3 of the other curtain wall unit 2 has a portion adjacent to the covering body 40 of the first curtain wall unit 2. The outdoor side surface 43 of the covering body 40 of one curtain wall unit 2 is flush with the outdoor-facing visible surface 3B of the portion of the frame body 3 of the other curtain wall unit 2 adjacent to the covering body 40. Here, the portion of the frame body 3 adjacent to the covering body 40 in the left-right direction is the first vertical frame 22 adjacent to the covering body 40, and the outdoor-facing visible surface 3B of the frame body 3 is the outdoor-facing visible surface of the first vertical frame 22. Furthermore, the outdoor-facing visible surface of the first vertical frame 22 is the outdoor-facing visible surface of the retaining portion 26 (batten 27) of the first vertical frame 22.

[0049] In curtain wall units 2 adjacent in the left-right direction, the outdoor side 43 of the covering body 40 of one curtain wall unit 2 and the outdoor sighting surface 3A of the frame body 3, and the outdoor sighting surface 3B of the frame body 3 of the other curtain wall unit 2, are arranged facing the outdoors. Furthermore, the outdoor side 43 of the covering body 40 of one curtain wall unit 2 is located between the outdoor sighting surface 3A of the frame body 3 of one curtain wall unit 2 and the outdoor sighting surface 3B of the frame body 3 of the other curtain wall unit 2. The outdoor side 43 of the covering body 40, the outdoor sighting surface 3A of the frame body 3, and the outdoor sighting surface 3B of the frame body 3 are aligned in the indoor-outdoor direction S, and are located on the same plane and are flush with each other.

[0050] The ventilation door 6, the duct connector 7, and the second closure panel body 33, and the cover body 40, are arranged apart in the indoor / outdoor direction S and facing each other in the indoor / outdoor direction S. The cover body 40 shields the ventilation door 6, the duct connector 7, and the second closure panel body 33 on the outdoor side, with a ventilation space 8 sandwiched between them. The ventilation space 8 is a space provided between the ventilation door 6, the duct connector 7, and the second closure panel body 33, and the cover body 40, and allows ventilation between the ventilation door 6, the duct connector 7, and the second closure panel body 33, and the cover body 40.

[0051] The ventilation space 8 is provided within the opening 5A of the ventilation section 5 of the curtain wall unit 2, and is located between the upper frame 20 and the lower frame 21 in the vertical direction, and between the vertical center frame 24 and the second vertical frame 23 in the left-right direction. The ventilation space 8 is also located on the indoor side of the covering body 40 and on the outdoor side of the ventilation door 6, duct connector 7, and second closure panel body 33. The air passage 42 of the covering body 40 opens toward the indoor ventilation space 8, and the duct connector 7 opens toward the outdoor ventilation space 8. When the ventilation door 6 is open, the ventilation opening 2C opens toward the outdoor ventilation space 8 and the indoor side.

[0052] The partition material 50 is disposed in the ventilation space 8 and separates the ventilation space 8 into a first space 8A on the ventilation door 6 side and a second space 8B on the duct connector 7 and second closure panel body 33 side. The first space 8A is the lower space of the ventilation space 8 and is located on the outdoor side of the ventilation door 6. The second space 8B is the upper space of the ventilation space 8 and is located on the outdoor side of the duct connector 7 and second closure panel body 33. The partition material 50 extends in the left-right direction between the vertical middle frame 24 and the second vertical frame 23, and is disposed across the entire left-right direction of the ventilation space 8. The first space 8A and second space 8B of the ventilation space 8 are separated in the up-down direction by the partition material 50 and are shielded from each other.

[0053] The partition material 50 slopes downward toward the outdoors from the location between the ventilation door 6 and the duct connector 7 and extends to the covering body 40. The location between the ventilation door 6 and the duct connector 7 is the horizontal frame 25 (the lower of the upper and lower horizontal frames 25) located between the ventilation door 6 and the duct connector 7. The partition material 50 is attached to the horizontal frame 25 and extends diagonally downward from the horizontal frame 25 toward the outdoors, protruding as far as the covering body 40. The partition material 50 is also located between the horizontal frame 25 and the covering body 40 within the ventilation space 8 and attached to the covering body 40.

[0054] The partition material 50 has an inclined portion 51 attached to the horizontal center frame 25 and a hanging portion 52 attached to the covering body 40. The inclined portion 51 slopes downward from the horizontal center frame 25 toward the outdoor side, extending diagonally downward and protruding to the covering body 40. The hanging portion 52 hangs downward from the outdoor-side end of the inclined portion 51 and is disposed along the covering body 40 on the indoor side of the covering body 40. The partition material 50 divides the ventilation space 8 into a first space 8A and a second space 8B by the inclined portion 51, thereby isolating the first space 8A from the second space 8B. When rainwater flows into the second space 8B of the ventilation space 8 through the air passage 42 of the covering body 40 above the partition material 50, the partition material 50 receives the rainwater by the inclined portion 51 and discharges the rainwater along the inclined portion 51 to the outdoor side.

[0055] In the curtain wall unit 2 and curtain wall 1 described above, the ventilation door 6 and duct connector 7 can be covered from the outdoor side by a common covering body 40. This makes it possible to easily improve the design of the curtain wall unit 2 equipped with the ventilation door 6 and duct connector 7 when viewed from the outdoor side. In addition, it is possible to prevent the structure of the curtain wall unit 2 from becoming complicated while ensuring the functionality of the ventilation door 6 and duct connector 7.

[0056] The partition material 50 blocks the air flow between the first space 8A and the second space B of the ventilation space 8 and prevents air from circulating between the ventilation door 6 and the duct connector 7. This prevents air discharged to the outdoors from the duct connector 7 from flowing indoors through the ventilation opening 2C opened by the ventilation door 6. The air is discharged to the outdoors from the duct connector 7 through the second space 8B and the air passage 42 of the cover 40. It also prevents air flowing to the outdoors through the ventilation opening 2C from flowing into the duct connector 7. The air flows from the ventilation opening 2C to the outdoors through the first space 8A and the air passage 42 of the cover 40. When rainwater flows into the ventilation space 8 above the partition material 50, the partition material 50 receives the rainwater and allows it to be easily discharged outdoors.

[0057] The covering body 40 is disposed adjacent to the outdoor panel body 30. As a result, the covering body 40 and the outdoor panel body 30 are arranged side by side on the outdoor side of the curtain wall unit 2, improving the design of the curtain wall unit 2 with a double-skin structure when viewed from the outdoor side. The outdoor side surface 43 of the covering body 40 is flush with the outdoor-facing visible surface 3A of the frame body 3. Therefore, the outdoor side surface 43 of the covering body 40 and the outdoor-facing visible surface 3A of the frame body 3 can be aligned in position in the indoor-outdoor direction S, further improving the design of the curtain wall unit 2 with a double-skin structure when viewed from the outdoor side.

[0058] In the ventilation section 5 of the curtain wall unit 2, the duct connector 7 may be disposed above the spandrel section 2A of the ventilation section 5, and the second closure panel body 33 may be disposed below the spandrel section 2A of the ventilation section 5. Alternatively, the duct connector 7 may be disposed in the vertical middle section of the spandrel section 2A of the ventilation section 5, and the second closure panel body 33 may be disposed on both the top and bottom sides of the duct connector 7. However, depending on the size or shape of the duct connector 7, the second closure panel body 33 may not be provided in the curtain wall unit 2. Multiple duct connectors 7 may be provided in the curtain wall unit 2.

[0059] The curtain wall unit 2 is not limited to a curtain wall unit having a double-skin structure, but may be another curtain wall unit (for example, a single-skin curtain wall unit having a single-skin structure). The single-skin curtain wall unit does not include panel bodies corresponding to the indoor-side panel body 31 and the first closure panel body 32, but includes a panel body corresponding to the outdoor-side panel body 30. In addition, the covering body 40 is not limited to a louver, but may be another breathable covering body.

[0060] Next, curtain wall units and curtain walls of other embodiments will be described.

As shown in the figure, the curtain wall 1 includes two types of curtain wall units 2D and 2E, similar to the curtain wall 1 of the second embodiment. However, in the second curtain wall unit 2E of the third embodiment, the covering body 40 has plate-like panels 44 instead of louvers.

[0071] The panels 44 of the covering body 40 are connected to the frame body 70 by connecting members 74. The panels 44 are disposed on the outdoor side of the frame body 70, spaced apart from the outdoor side of the frame body 70. When the covering body 40 has one panel 44, the panel 44 extends in the vertical direction along the vertical frames 71, 72 of the frame body 70. In contrast, when the covering body 40 has multiple panels 44, the multiple panels 44 are arranged side by side in the vertical direction. The covering body 40 allows ventilation between the outdoor side and the indoor side of the covering body 40 through the gap between the panel 44 and the frame body 70. Note that the covering body 40 having the panels 44 may be provided in the curtain wall unit 2 of the first embodiment.

[0072] (Fourth embodiment) FIG. 9 is a cross-sectional view showing the curtain wall 1 of the fourth embodiment, and shows the curtain wall 1 cut in the left-right direction at the vision section 2B, similar to FIG.
