[Figure 9] This is a perspective view showing the lighting on each floor of the building in the embodiment. [Modes for carrying out the invention]

[0008] Hereinafter, an embodiment of the building described herein will be explained using Figures 1 to 9. Figure 1 is a front view of building 10, and Figure 2 is an enlarged front view of the main part of the fourth floor of building 10 shown in Figure 1. Figure 3 is a section 3-3 in Figure 2, and Figure 4 is a longitudinal cross-sectional view of the fourth floor of building 10.

[0009] As shown in Figure 1, building 10 has six floors. The first floor (F1) and second floor (F2) of building 10 are constructed using a known piloti structure. The third floor (F3) of building 10, excluding the central part, the fourth floor (F4), fifth floor (F5), and sixth floor (F6) of building 10 have almost the same configuration. Here, we will describe the configuration of the fourth floor (F4) of building 10.

[0010] As shown in Figures 2 and 3, the fourth floor F4 of building 10 is provided with mullions 11 arranged at approximately equal intervals horizontally, and transoms 12 connecting the lower ends of the mullions 11. Transparent glass panels 25, which have transparency as an exterior material, are provided between these mullions 11. In addition, a surface panel 35 of a panel member P1, which will be described later, is positioned above the glass panels 25 between the mullions 11.

[0011] As shown in Figure 4, the floor slab S4 of the 4th floor F4 also serves as the ceiling slab of the 3rd floor F3 and is formed on top of beam 21a. Furthermore, the ceiling slab S5 of the 4th floor F4 also serves as the floor slab of the 5th floor F5 and is formed on top of beam 21b. Beams 21a and 21b are made of H-shaped steel having a lower flange, an upper flange, and a web. The lower flanges of beams 21a and 21b are fixed to the upper ends of mullions 11 via connecting members 22. Transoms 12 are formed on top of floor slab S4 and ceiling slab S5.

[0012] A dropped wall 24 is formed around the outer perimeter of the slabs (S4, S5). This dropped wall 24 is fixed to the mullions 11. A vertically positioned hanger 26 is provided on the underside of the ceiling slab S5. The hanger 26 supports the ceiling member 30. A curtain rail CL1 is provided between the mullions 11 at approximately the same height as the ceiling member 30.

[0013] Furthermore, the brace member 31 is provided to diagonally connect the ceiling slab S5 and the hanger 26. Figure 5 is an enlarged view of the configuration from a position (height) slightly lower than the ceiling member 30 to the ceiling slab S5 in Figure 4.

[0014] On the suspension member 26, the indoor-side end of the attachment member 32 is fixed at a position above the connection part with the brace member 31. The outdoor-side end of this attachment member 32 is attached to the upper part of the inclined support member 33. The lower part of this inclined support member 33 is fixed to the eaves edge member 27 provided at the lowermost part of the suspension member 26. The inclined support member 33 is a member for attaching the panel member P1. This inclined support member 33 is attached at an angle corresponding to the inclination of the panel member P1. In the present embodiment, the panel member P1 is arranged at an inclination such that it approaches the glass plate 25 as it goes upward. For example, the panel member P1 has an inclination of about 50 degrees with respect to the horizontal plane.

[0015] Below the panel member P1, a lighting fixture 40 is arranged. The lighting fixture 40 has the shape of a long object like a fluorescent lamp and extends in a direction orthogonal to the plane of the drawing. In the present embodiment, this lighting fixture 40 irradiates artificial light of a bulb color (color temperature: around about 2700K) suitable for a warm and relaxing space.

[0016] The panel member P1 has a front-side panel 35 and a back-side panel 36. The front-side panel 35 is arranged on the side of the glass plate 25. The back-side panel 36 is provided along the inclined support member 33 at an interval of, for example, about 20 mm from the front-side panel 35.

[0017] The front-side panel 35 has a rectangular reflection part 35a, a plurality of upper attachment parts 35b provided apart from the upper end part of the reflection part 35a, and a lower attachment part 35c provided at the lower end part of the reflection part 35a.

[0018] FIG. 6 and FIG. 8 are enlarged views of the upper and lower parts of the front-side panel 35 in FIG. 5, respectively. FIG. 7 is an enlarged view of the main part of FIG. 6 as seen from the outdoor side. As shown in FIG. 6, the upper attachment part 35b of the front-side panel 35 and the upper end part of the back-side panel 36 are fixed to the member 11a constituting the upright 11 by bolts B1.

[0019] The reflective portion 35a of the surface panel 35 is made of steel plate and acts as a reflector that reflects the artificial light from the lighting fixture 40. The lower surface (glass plate 25 side) of the reflective portion 35a is coated with acrylic baked paint. This improves durability and reflectivity.

[0020] As shown in Figure 7, the back panel 36 is a steel plate with numerous holes 36h formed by punching. The back panel 36 functions as a ventilation member. The back panel 36 is positioned above the reflective portion 35a of the front panel 35 so that multiple holes 36h are exposed. The back panel 36 is positioned along the inclined support member 33.

[0021] As shown in Figure 8, the lowest part of the rear panel 36 is fixed to the inclined support member 33 by bolt B6. Furthermore, the lower mounting portion 35c of the front panel 35 and the upper end of the upper part 37a of the back plate member 37 are fixed to the inclined support member 33 by bolt B5, which is located above bolt B6.

[0022] The backing plate member 37 has an upper part 37a, a central part 37b, and a lower part 37c. The upper part 37a of the backing plate member 37 is sloped along the inclined support member 33. The central part 37b of the backing plate member 37 has an L-shaped cross-section and demarcates the space for arranging the lighting fixture 40. The lower part 37c of the backing plate member 37 is fixed to a part of the furring strip member 27 with bolts B7.

[0023] A removable panel 38 is provided on the outdoor side of the back plate member 37. This removable panel 38 has a covering portion 38a that covers the outdoor side of the lighting fixture 40, and a plate-shaped mounting portion 38b located below it. When the mounting portion 38b is fixed to the lower part 37c of the back plate member 37 with bolts B8, the covering portion 38a rests on the horizontal portion of the central part 37b of the back plate member 37. The removable panel 38 can be removed to the right by removing these bolts B8. In this case, the lighting fixture 40 can be replaced from the removable panel 38 side.

[0024] As shown in Figure 4, in the configuration described above, the area below the ceiling member 30 constitutes a living space S1. The inside of the glass plate 25 and the surface panel 35 of the panel member P1 are located in this living space S1. Above the ceiling member 30 is the space above the ceiling, S2. The living space S1 and the space above the ceiling, S2, are connected through multiple holes 36h in the rear panel 36.

[0025] As shown in Figure 9, the lighting fixture 40 is turned on at night. In this case, the artificial light from the lighting fixture 40 is reflected by the reflective portion 35a of the surface panel 35, resulting in indirect lighting of a warm white color that is visible through the glass plate 25. Therefore, from the outside of the building 10, it appears as if a straight line of light is arranged horizontally for each floor.

[0026] (Effect of the embodiment) A panel member P1 is provided at the top of the glass plate 25, which is positioned between multiple mullions 11, and a lighting fixture 40 is provided below the panel member P1. The artificial light from the lighting fixture 40 is reflected by the surface panel 35 of the panel member P1 and is emitted outside from the glass plate 25.

[0027] (Effects of the embodiment) (1) In this embodiment, the reflective portion 35a of the surface panel 35 of the panel member P1 is positioned diagonally above the glass plate 25 which is placed between the mullions 11 from the 4th floor F4 to the 6th floor F6. When the lighting fixture 40 is turned on, the artificial light from the lighting fixture 40 is reflected by the reflective portion 35a of the surface panel 35 and can be seen through the glass plate 25. As a result, indirect lighting arranged in a straight line horizontally is projected directly above the glass plate 25 from the 4th floor F4 to the 6th floor F6, thus achieving a unified appearance in the building 10. In addition, during the daytime, sunlight entering the room from the outside through the glass plate 25 is reflected by the reflective portion 35a, thus reducing direct sunlight.

[0028] (2) In this embodiment, the back panel 36 of the panel member P1 is provided with a plurality of holes 36h. As a result, the back panel 36 is exposed above the reflective portion 35a of the panel member P1. The living space S1 is connected to the ceiling space S2 through the holes 36h of the back panel 36. As a result, if smoke or heat buildup occurs in the living space S1, it can be discharged into the ceiling space S2 through the holes 36h of the back panel 36.

[0029] (3) In this embodiment, the inclined support member 33 is positioned along the back side panel 36 of the panel member P1, with the inclined support member 33 positioned according to the angle of the panel member P1. This makes it easy to position the reflective portion 35a of the front side panel 35, which is positioned with a gap between it and the back side panel 36, at a desired angle.

[0030] (4) In this embodiment, a back plate member 37 is attached to the inclined support member 33 to which the panel member P1 is attached, forming a space for arranging the lighting fixture 40. This allows the lighting fixture 40 to be efficiently positioned below the reflector 35a.

[0031] (5) In this embodiment, the covering portion 38a of the removable panel 38 is placed on the outdoor side of the lighting fixture 40. As a result, the artificial light from the lighting fixture 40 does not pass through the covering portion 38a, and thus diffusion to the outside directly from the side through the glass plate 25 can be suppressed.

[0032] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically. In the above embodiment, the multiple holes 36h of the back panel 36 are exposed above the reflective portion 35a of the front panel 35. The communication holes connecting the living space S1 and the ceiling space S2 are not limited to the shape of multiple holes formed by punching. For example, they may be formed by a member configured to surround a large communication space with mounting parts.

[0033] In the above embodiment, the configurations on both sides of the 3rd floor F3 and from the 4th floor F4 to the 6th floor F6 of the building 10 were the same. The angle of the reflective section 35a may be changed depending on the floor. For example, the angle of the reflector placed on the top floor, the 6th floor, may be set to an angle that is longer in the vertical direction. Alternatively, the angle of the reflector may be set to gradually become longer in the vertical direction as the floor increases. In these cases, when looking up at the building 10 from below, the distance from the point of view to the upper floors increases, so by increasing the vertical length of the reflector, the artificial light reflected by the reflector can be made to appear to have a more uniform width, even if the floors are different.

[0034] In the above embodiment, the warm-colored artificial light from the lighting fixture 40 was reflected by the reflective portion 35a of the surface panel 35. In this case, the color of the artificial light emitted by the lighting fixture 40 and the color of the reflector may be changed.
