Description

[Technical Field]

[0001] The present invention relates to a mounting structure for a lighting device in a curtain wall in which a lighting device is provided in a spandrel portion, and to a curtain wall. [Background technology]

[0002] In curtain walls installed on the walls of buildings, lighting devices are sometimes installed in the blinds of the curtain wall to provide illumination for the exterior design of the building. For maintenance of the lighting devices, for example, the lighting devices may be attached to an openable cover of the blind, or the interior portion of the blind located on the interior side of the room relative to the lighting devices may be made removable. However, lighting devices installed in the blinds cannot meet the need to install lighting devices at any position above or below the spandrel portion of the curtain wall for illumination. In response to this, a lighting device for curtain walls that illuminates the spandrel portion using a lighting device has been known in the past (see Patent Document 1).

[0003] In the conventional curtain wall lighting device described in Patent Document 1, the lighting device is attached to a mullion and emits LED light in the vertical and horizontal in-plane directions. However, conventional curtain wall lighting devices are installed integrally with the mullion and are located in the spandrel section, which makes maintenance difficult. Therefore, it is not easy to remove or replace the lighting device from the mullion, and maintenance of the lighting device is time-consuming. [Prior art documents] [Patent documents]

The holder 70 supports and holds the lower end 58 of the lighting base 50 from below the lower end 58 of the lighting base 50. The holder 70 is a fixture that fixes the lighting base 50, and fixes the lower end 58 of the lighting base 50 and fixes the lighting base 50 to the spandrel section 2A.

[0038] The holder 70 has a mounting portion 72 on which the lower end portion 58 of the lighting base 50 is mounted, a wiring portion 73 on which the wiring 31 is arranged, and a lid portion 74 that covers the wiring portion 73. The mounting portion 72 of the holder 70 is a plate-shaped support and cover portion located below the lower end portion 58 of the lighting base 50. The lower end portion 58 of the lighting base 50 is mounted on the mounting portion 72 from above, and is supported and held from below by the mounting portion 72, which is a support portion. In addition, the lower end portion 58 of the lighting base 50 is covered from below by the mounting portion 72, which is a cover portion, and is shielded on the vision unit 2B side.

[0039] The wiring section 73 of the holder 70 is a space for wiring (wiring path section) located in the wiring path of the holder 70, and is located on the indoor side of the lighting base 50 and the wiring space 54, and is arranged from the lighting base 50 and the wiring space 54 toward the indoor side. The wiring section 73 of the holder 70 and the wiring space 54 of the lighting base 50 are connected to each other by an insertion port (not shown) through which the wiring 31 is inserted. The wiring 31 extends from the lighting device 30 through the wiring space 54 to the wiring section 73 and is housed in the wiring section 73. The wiring section 73 passes the wiring 31 extending from the lighting device 30 toward the indoor side. The wiring 31 extends through the wiring section 73 toward the indoor side of the holder 70 and the curtain wall 1. The wiring 31 also extends from the wiring section 73 toward the connection section on the building 10 side and connects to the connection section on the building 10 side.

[0040] The lid portion 74 of the holder 70 is detachably attached to the wiring portion 73, and shields the wiring 31 and bolts 71 inside the wiring portion 73. When attaching the holder 70, with the lid portion 74 removed from the wiring portion 73, the bolts 71 are inserted inside the wiring portion 73, and the wiring portion 73 and the holder 70 are attached to the vertical member 40 by the bolts 71. Next, the lid portion 74 is attached to the wiring portion 73. When removing the holder 70, the lid portion 74 is removed from the wiring portion 73, the bolts 71 are removed, and the holder 70 is removed from the vertical member 40.

[0041] Fig. 7 is a vertical cross-sectional view showing a state during maintenance of the lighting device 30 in the lighting mounting structure 3 of the first embodiment. In Fig. 7, the second indoor side panel body 22 in the open state is schematically shown by a two-dot chain line. As shown in the figure, when performing maintenance on the lighting device 30, the second indoor panel body 22 is opened in the interior space 14 of the building 10 to open the space 23 of the curtain wall unit 2 located in the vision section 2B. Next, in the space 23 (opening 4A of the frame body 4), the holder 70 is removed from the vertical member 40 to release the holding of the lighting base 50 by the holder 70. Next, the lighting base 50 is moved downward along the guide member 60 within the space 23 from the spandrel section 2A to the vision section 2B. At this time, the lighting base 50 is guided by the guide member 60 from the spandrel section 2A to the vision section 2B, exits the spandrel section 2A, and moves to the vision section 2B.

[0042] As the lighting base 50 moves, the wiring 31 is arranged so that it is pulled out from the boundary portion 13 of the building 10 toward the outside of the room and extends to the vision section 2B. Alternatively, the connection point of the wiring 31 is arranged inside the wiring section 73 of the holder 70, and the connection point of the wiring 31 is detached inside the wiring section 73 before the holder 70 is removed from the vertical member 40. The lighting base 50 is guided by the guide member 60 and moves to the space section 23 of the curtain wall unit 2 located in the vision section 2B. Next, the lighting base 50 is moved inside the room (indoor space 14) to perform maintenance on the lighting device 30 (for example, removing the lighting device 30 from the lighting base 50, repairing the lighting device 30, or replacing the lighting device 30).

[0043] After maintenance of the lighting device 30 is completed, the lighting base 50 is moved upward along the guide member 60 within the space 23 from the vision section 2B to the spandrel section 2A. At this time, the lighting base 50 is guided by the guide member 60 from the vision section 2B to the spandrel section 2A and placed in the spandrel section 2A. Next, in the space 23, the holder 70 is attached to the vertical member 40, and the lighting base 50 is held in the spandrel section 2A by the holder 70. Next, the second indoor panel body 22 is closed to close the space 23 of the curtain wall unit 2 located in the vision section 2B.

[0044] As described above, in the curtain wall 1 and lighting mounting structure 3 of the first embodiment, the lighting base 50 can be moved from the spandrel section 2A to the vision section 2B, facilitating maintenance of the lighting device 30 provided in the spandrel section 2A of the curtain wall 1. Furthermore, by attaching the lighting device 30 to any position in the longitudinal direction of the lighting base 50, the lighting device 30 can be installed at any position in the vertical direction in the spandrel section 2A.

[0045] The holder 70 supports the lighting base 50 from below, enabling the lighting base 50 to be stably held on the spandrel section 2A. Furthermore, the mounting section 72 of the holder 70 stably supports the lower end section 58 of the lighting base 50 while preventing the lower end section 58 of the lighting base 50 from being exposed to the vision section 2B side.

[0046] The wiring 31 of the lighting device 30 can be neatly routed through the wiring space 54 of the lighting base 50 to the holder 70. Also, the wiring 31 of the lighting device 30 can be neatly routed toward the indoor side through the wiring section 73 of the holder 70. As a result, the appearance of the lighting mounting structure 3 can be improved, and the design of the lighting mounting structure 3 can be enhanced.

[0047] By providing the guide member 60 only on the spandrel portion 2A, it is possible to reduce exposure of the guide member 60 on the vision portion 2B side, thereby improving the design of the lighting mounting structure 3. The guide member 60 is attached to the visible surface 42 of the vertical member 40. This allows the lighting device 30 to be connected to the visible surface 42 of the vertical member 40, and the lighting device 30 to provide illumination from the visible surface 42 of the vertical member 40.

[0048] (Second embodiment) Next, a curtain wall 1 and a lighting mounting structure 3 of a second embodiment will be described. In the curtain wall 1 and the lighting mounting structure 3 of the second embodiment, explanations of the same matters as those in the curtain wall 1 and the lighting mounting structure 3 of the first embodiment will be omitted, and the following mainly describes the matters that differ from the curtain wall 1 and the lighting mounting structure 3 of the first embodiment. Furthermore, in relation to the curtain wall 1 and the lighting mounting structure 3 of the second embodiment, the same names as those in the curtain wall 1 and the lighting mounting structure 3 of the first embodiment will be used for the configurations that correspond to those in the curtain wall 1 and the lighting mounting structure 3 of the first embodiment.

[0049] FIG. 8 is a cross-sectional view showing a spandrel portion 2A of a curtain wall 1 according to the second embodiment, and shows an enlarged view of a part of the curtain wall unit 2, similar to FIG. As shown in the figure, the curtain wall unit 2 of the curtain wall 1 includes a rib 80 arranged at least in the spandrel portion 2A. The rib 80 extends vertically between the left and right vertical frames 7, 8 and is connected to the top frame 5 and the crossbeam 9. The rib 80 is spaced apart from the outdoor panel body 20 toward the indoor side and is located on the indoor side of the outdoor panel body 20 and the space portion 23. The first indoor-side panel body 21 is divided in the left-right direction and is arranged on both the left and right sides of the rib 80 and attached to the rib 80. The rib 80 is arranged between the left and right first indoor-side panel bodies 21 and holds the left and right first indoor-side panel bodies 21.

[0050] The lighting mounting structure 3 is provided on a vertical member 90, which is a central rib 80. The vertical member 90 (central rib 80) has an opening side portion 91 and a sighting surface 92 located on the opening 4A side (space 23 side) of the frame body 4. The opening side portion 91 of the vertical member 90 is the portion of the vertical member 90 facing the opening 4A (space 23) of the frame body 4. The sighting surface 92 of the vertical member 90 is the exterior side located in front of the outdoor side (space 23 side) of the vertical member 90, and is arranged facing the outdoor side, facing the indoor side of the outdoor panel body 20 in the indoor-outdoor direction. In the spandrel portion 2A, the lighting mounting structure 3 is provided on the opening side portion 91 and the sighting surface 92 of the vertical member 90, and is arranged in the opening 4A and space 23 of the frame body 4.

[0051] In the opening 4A and space 23 of the frame body 4, the lighting mounting structure 3 and each part 30, 50, 60, 70 of the lighting mounting structure 3 are arranged on the outdoor side of the visible surface 92 of the vertical member 90, and are located between the outdoor panel body 20 and the visible surface 92 of the vertical member 90. In addition, the lighting mounting structure 3 and each part 30, 50, 60, 70 of the lighting mounting structure 3 are arranged spaced apart from the outdoor panel body 20 toward the indoor side in the indoor-outdoor direction. The lighting mounting structure 3, lighting base 50, and guide member 60 extend in the up-and-down direction (the longitudinal direction of the vertical member 90) along the opening side part 91 and the visible surface 92 of the vertical member 90.

[0052] The lighting base 50 does not have a light-blocking material 56, and the engagement portions 57 of the lighting base 50 are formed in two locations spaced apart in the left-right direction of the connecting portion 51. The storage portion 52, hollow portion 53, and wiring space 54 of the lighting base 50 are located on the outdoor side of the connecting portion 51. The guide member 60 is attached to a visible surface 92 on the outdoor side of the vertical member 90, and the rail portions 61 of the guide member 60 are formed in two locations spaced apart in the left-right direction of the guide member 60. The holder 70 (not shown in FIG. 8 ) and the lighting base 50 are arranged to protrude from the visible surface 92 of the vertical member 90 to the outdoor side. The holder 70 is attached to the opening side portion 91 and the visible surface 92 of the vertical member 90, and the wiring portion 73 of the holder 70 is located below the lighting base 50 and the wiring space 54.

[0053] By attaching the guide member 60 to the sighting surface 92 of the vertical member 90, the lighting device 30 can be connected to the sighting surface 92 of the vertical member 90, and the lighting device 30 can provide illumination from the sighting surface 92 of the vertical member 90.

[0054] The lighting mounting structure 3 and its components 30, 50, 60, and 70 may be positioned indoors without being spaced apart from the outdoor panel body 20. The vertical member 90 may be provided at one or more locations in the left-right direction at the opening 4A of the frame body 4. When the vertical members 90 are provided at multiple locations, the lighting mounting structure 3 may be provided at one or more of the vertical members 90, or may be provided at all of the vertical members 90. The retainer 70 may be a bolt attached to the vertical members 40 and 90. For example, the bolt is attached to the vertical members 40 and 90 by passing through an insertion hole in the lighting base 50. The lighting base 50 is fixed to the vertical members 40 and 90 by the bolt and held to the spandrel portion 2A. Alternatively, the lower end portion 58 of the lighting base 50 may be supported by a bolt attached to the vertical members 40 and 90.

[0055] The present invention is not limited to the lighting mounting structure 3 in a curtain wall 1 having a curtain wall unit 2, but can be applied to lighting mounting structures in various curtain walls (for example, curtain walls having mullions and transoms). Therefore, the lighting mounting structure is not limited to the vertical frames 7, 8 or ribs 80, but can be installed on the vertical members of various curtain walls. Furthermore, the spandrel portion 2A may be located above the vision portion 2B or below the vision portion 2B.

[0056] As mentioned above, the installation structure of the curtain wall lighting device is as follows: A mounting structure for a lighting device of a curtain wall in which a lighting device is provided on a spandrel section adjacent to a vision section in the vertical direction, A vertical member extending in the vertical direction in the spandrel portion; a lighting base disposed on the spandrel portion and having the lighting device attached thereto; a guide member attached to the vertical member, to which the lighting base is movably coupled, and which guides the lighting base from the spandrel portion toward the vision portion; a holder that holds the lighting base on the spandrel portion; The present invention relates to a mounting structure for a lighting device on a curtain wall. Therefore, since the lighting base can be moved from the spandrel section to the vision section, maintenance of the lighting device installed in the spandrel section of the curtain wall can be easily performed.

[0057] The spandrel portion is located above the vision portion, The holder supports and fixes the lower end of the lighting base. Therefore, the lighting base can be supported from below by the holder, and the lighting base can be stably held on the spandrel portion.

[0058] The holder has a mounting portion on which a lower end portion of the lighting base is mounted, the mounting portion covering the lower end portion of the lighting base from below. Therefore, the mounting portion of the holder can stably support the lower end of the lighting base while preventing the lower end of the lighting base from being exposed to the vision section.

[0059] The lighting base has a wiring space through which wiring extending from the lighting device is passed to the holder. Therefore, the wiring of the lighting device can be neatly routed to the holder through the wiring space of the lighting base.

[0060] The holder has a wiring portion through which wiring extending from the lighting device passes toward the indoor side. Therefore, the wiring of the lighting device can be neatly routed toward the interior of the room through the wiring portion of the holder.

[0061] The guide members are provided only on the spandrel portions. Therefore, exposure of the guide member to the vision section side can be suppressed, thereby improving the design of the mounting structure for the lighting device on the curtain wall.

[0062] The guide members are attached to the visible faces of the vertical members. Therefore, by connecting a lighting device to the visible surface of the vertical member, the lighting device can provide illumination from the visible surface of the vertical member.

[0063] The guide member is attached to the exterior facing surface of the vertical member. Therefore, by connecting a lighting device to the outdoor facing surface of the vertical member, the outdoor facing surface of the vertical member can be illuminated by the lighting device.

[0064] The curtain wall is a curtain wall equipped with a mounting structure for a curtain wall lighting device. Therefore, maintenance of the lighting devices installed in the spandrel portions of the curtain wall can be easily carried out. [Explanation of symbols]
