  Hereinafter, the present invention will be described more specifically by way of example with reference to the drawings.

  A building 1 according to an embodiment of the present invention shown in FIG. 1 is a three-story industrialized house having a steel frame structure, and has three floors of a first floor portion 2, a second floor portion 3 and a third floor portion 4. have. The first floor portion 2 and the second floor portion 3 are separated by a floor slab 5, and the second floor portion 3 and the third floor portion 4 are separated by a floor slab 6. The floor slab 5 is a floor structure that supports the load of the floor of the second floor portion 3 of the building 1, and the floor slab 6 is a floor structure that supports the load of the floor of the third floor portion 4 of the building 1.

  Although not shown in detail, the first floor 2 of the building 1 is provided with an entrance, a storage room, a bathroom, etc., and the second floor 3 has a living room (living room), a dining room (dining room), a kitchen (kitchen), etc. A living room such as a bedroom is provided on the third floor portion 4. Further, the second floor portion 3 is provided with a blow-through 7 that reaches the ceiling surface 4a of the third floor portion 4 by cutting out a part of the floor slab 6.

  In such a building 1, the lighting system S is arranged on the overhanging portion 10 provided at the stepped portion of the ceiling. In the following, first, the configuration of the stepped portion of the ceiling and the configuration of the overhanging portion 10 will be described.

  In this building 1, a part of the floor slab 6 that separates the second-floor portion 3 and the third-floor portion 4 is shifted to the upper floor side with respect to the other portions so that the ceiling height of the second-floor portion 3, that is, the floor surface 3b to the ceiling surface 3a. The height of the part is partially increased. By partially increasing the ceiling height of the second-floor portion 3 in a region where a living room such as a living room is provided, the living room can be given a feeling of openness, thereby making the room feel wider and enhancing its comfort. ..

  More specifically, the floor slab 6 is supported by the body of the building 1 at a standard height and constitutes a part of the floor slab 6, and the first slab portion 6a. And a second slab portion 6b disposed on the upper floor side, that is, on the third floor portion 4 side with a predetermined height offset.

  The 2nd slab part 6b can be provided in the area|region which matched the grid of the frame structure of the steel frame structure of the building 1 of the floor slab 6, for example. With such a configuration, the second slab portion 6b can be reliably supported by the body with a simple configuration. Further, in this case, another beam may be arranged above the beam that supports the first slab portion 6a so that the second slab portion 6b is supported by the beam that is overlapped on the upper side. With such a configuration, the second slab portion 6b can be reliably supported by the frame on the upper floor side of the first slab portion 6a with a simple configuration.

  The shift amount (shift amount) of the second slab portion 6b with respect to the first slab portion 6a to the upper floor side can be set to, for example, about 30 cm.

  The first slab portion 6a and the second slab portion 6b are provided in a region where the thickness of the floor slab 6 (the thickness from the ceiling surface 3a of the second floor portion 3 to the floor surface 4b of the third floor portion 4) is substantially constant, that is, The thickness of the second slab portion 6b is substantially the same as the thickness of the first slab portion 6a.

  In the illustrated case, the floor slab 6 has a constant thickness over the entire area, but the floor slab 6 is configured to have a region having a different thickness in addition to a region having a constant thickness. You can also In this case, both the first slab portion 6a and the second slab portion 6b are provided in a region where the thickness of the floor slab 6 is constant.

  As described above, in this building 1, the second slab portion 6b having substantially the same thickness as the first slab portion 6a is provided to the first slab portion 6a that constitutes a part of the region where the floor slab 6 has a constant thickness. By shifting to the upper floor side with respect to the 1 slab portion 6a, there is less restriction on the size and height of the region where the ceiling height is increased, and the ceiling height of the second floor portion 3 is reduced without reducing the thickness of the floor slab 6. I try to raise it partially. Thereby, the thickness of the floor slab 6 is ensured to be a predetermined thickness, the sound insulation by the floor slab 6 between the second floor portion 3 and the third floor portion 4 is secured, and the ceiling height of the desired area of the second floor portion 3 is controlled. Can be higher.

  By arranging the second slab portion 6b so as to be displaced from the first slab portion 6a on the side of the third floor portion 4 by a predetermined height, the floor surface 4b of the third floor portion 4 is provided with the first slab portion 6a. A first floor surface 4b1 formed by the upper surface and a second floor surface 4b2 formed by the upper surface of the second slab portion 6b are provided. The second floor surface 4b2 is displaced upward with respect to the first floor surface 4b1 and has a step with respect to the first floor surface 4b1, while the ceiling height of the third floor portion 4 is constant, The ceiling height of the area corresponding to the second floor surface 4b2 of the third floor portion 4 is lower than that of the area corresponding to the first floor surface 4b1. Therefore, it is preferable that the second floor surface 4b2 is provided in a region such as a bedroom or a storage room that does not require a high ceiling height.

  In this building 1, the kitchen is provided in the second floor portion 3 where the ceiling height is increased by shifting the second slab portion 6b with respect to the first slab portion 6a as described above. With such a configuration, it is possible to increase the ceiling height of a living room such as a living room and a dining room provided on the second floor portion 3 together with the kitchen, and enhance the comfort of the living room.

  When the ceiling height of the second floor portion 3 is increased by the above configuration, the ceiling surface 3a of the second floor portion 3 has the first ceiling surface 3a1 formed by the lower surface of the first slab portion 6a and the lower surface of the second slab portion 6b. The formed second ceiling surface 3a2 is provided. The second ceiling surface 3a2 is displaced upward with respect to the first ceiling surface 3a1 and has a step with respect to the first ceiling surface 3a1, and between the first ceiling surface 3a1 and the second ceiling surface 3a2. They are connected to each other by a connecting surface 3a3 perpendicular to these surfaces. In this way, by shifting the second slab portion 6b to the upper floor side with respect to the first slab portion 6a to increase the ceiling height, the ceiling surface 3a of the second floor portion 3 has the first ceiling surface 3a1 and the first ceiling surface 3a1. A step formed by the second ceiling surface 3a2, which is higher than the surface 3a1, is generated.

  As described above, when the ceiling surface 3a of the second-floor portion 3 has a shape having a simple step in which the first ceiling surface 3a1 and the second ceiling surface 3a2 are connected by the connecting surface 3a3, the step causes space A sense of discontinuity will occur and the aesthetics of the ceiling will be impaired. Therefore, in this building 1, a side portion of the first ceiling surface 3a1 and the second ceiling surface 3a2, which is the lower side, of the first ceiling surface 3a1 projects laterally along the first ceiling surface 3a1. The overhanging portion 10 is provided to enhance the aesthetic appearance of the ceiling.

  As shown in FIGS. 2 and 3, the overhanging portion 10 is formed in a long plate shape extending along the outer peripheral edge of the first ceiling surface 3a1, and the lower surface 10a is flush with the first ceiling surface 3a1. Are arranged in parallel to the first ceiling surface 3a1 and the second ceiling surface 3a2, and are fixed to the side portions of the first slab portion 6a at the side portions thereof. In addition, the thickness of the overhanging portion 10 is smaller than the step (difference in height) between the first ceiling surface 3a1 and the second ceiling surface 3a2, so that the overhanging portion 10 is spaced apart from the second ceiling surface 3a2. Are arranged in a stack. In the illustrated case, the overhanging portion 10 is formed in an L-shape having a first overhanging portion 10A and a second overhanging portion 10B that is bent and connected at a right angle to the first overhanging portion 10A.

  As described above, in this building 1, since the overhanging portion 10 is provided in the step portion between the first ceiling surface 3a1 and the second ceiling surface 3a2, compared with the case where a simple step is provided on the ceiling surface 3a, It is possible to enhance the sense of continuity of the space in the step portion and enhance the aesthetic appearance of the ceiling.

  The overhanging portion 10 can be configured, for example, by attaching a gypsum board or the like to the surface of a plate-shaped base material. In this case, by extending the base material and the gypsum board forming the first slab portion 6a and integrally forming the base material and the gypsum board forming the extension portion 10, the extension portion 10 and the first slab portion 6a are integrated. It can also be formed. Accordingly, the overhanging portion 10 can be easily formed together with the first slab portion 6a.

  The thickness of the overhanging portion 10 can be set to, for example, about 12.5 cm. By setting the overhanging portion 10 to have such a thickness, it is possible to secure a desired strength while maintaining an appropriate distance from the second ceiling surface 3a2.

  On the other hand, as shown in FIG. 1, a part of the floor slab 5 separating the first-floor portion 2 and the second-floor portion 3 is displaced to the lower floor side with respect to the other portions, so that the second-floor portion 3 has its floor. Part of the surface 2b is partially lowered to increase the ceiling height in the area.

  More specifically, the floor slab 5 is supported by the body of the building 1 at a reference height and constitutes a part of the floor slab 5, and the first slab portion 5a. The second slab portion 5b is arranged on the lower floor side, that is, on the first floor portion 2 side with a predetermined height offset (lowered).

  Similar to the second slab portion 6b described above, the second slab portion 5b can also be provided in a region of the floor slab 5 that is aligned with the grid of the steel frame structure of the building 1. With such a configuration, the second slab portion 5b can be reliably supported by the body with a simple configuration.

  The shift amount (shift amount) of the second slab portion 5b to the lower floor side with respect to the first slab portion 5a can be set to, for example, about 30 cm.

  The first slab portion 5a and the second slab portion 5b are provided in a region where the thickness of the floor slab 5 (the thickness from the ceiling surface 2a of the first floor portion 2 to the floor surface 3b of the second floor portion 3) is substantially constant, that is, The thickness of the second slab portion 5b is substantially the same as the thickness of the first slab portion 5a.

  With such a configuration, the second floor surface 3b2 formed by the upper surface of the second slab portion 5b is displaced downward from the first floor surface 3b1 formed by the upper surface of the first slab portion 5a. In this way, the ceiling height of the second floor portion 3 can be increased without reducing the thickness of the floor slab 5 in the area of the second floor surface 3b2. That is, it is possible to increase the ceiling height of the second-floor portion 3 while ensuring the thickness of the floor slab 5 and ensuring sound insulation by the floor slab 5 between the first-floor portion 2 and the second-floor portion 3. In this case as well, both the first slab portion 5a and the second slab portion 5b are provided in a region where the thickness of the floor slab 5 is constant.

  In addition, the second slab portion 5b of the floor slab 5 is arranged on the first floor portion 2a side by being lowered by a predetermined height with respect to the first slab portion 5a, while the floor surface 2b of the first floor portion 2 has a constant height. Therefore, the area of the first floor portion 2 where the second ceiling surface 2a2 is provided has a lower ceiling height than the area where the first ceiling surface 2a1 is provided. Therefore, it is preferable that the second ceiling surface 2a2 is provided in a region such as a storage door, which does not require a high ceiling height.

  If the second slab portion 5b is shifted to the lower floor side with respect to the first slab portion 5a so that the ceiling height of the second floor portion 3 is increased, the ceiling surface 2a of the first floor portion 2 has the first slab portion 5a of the first slab portion 5a. A first ceiling surface 2a1 formed by the lower surface and a second ceiling surface 2a2 formed by the lower surface of the second slab portion 5b are provided. The second ceiling surface 2a2 is shifted downward with respect to the first ceiling surface 2a1 and has a step with respect to the first ceiling surface 2a1, and between the first ceiling surface 2a1 and the second ceiling surface 2a2. They are connected to each other by a connecting surface 2a3 that is perpendicular to these surfaces. Thus, the ceiling surface 2a of the first-floor portion 2 has a step formed by the first ceiling surface 2a1 and the second ceiling surface 2a2 lower than the first ceiling surface 2a1, but in this case also, By providing the overhanging portion 10 projecting laterally along the second ceiling surface 2a2 on the side of the second ceiling surface 2a2 that is the lower side of the first ceiling surface 2a1 and the second ceiling surface 2a2. , I try to enhance the aesthetics of the ceiling.

  The configuration of the overhanging portion 10 provided on the side portion of the second ceiling surface 2a2 of the first floor portion 2 is basically the same as the configuration of the overhanging portion 10 provided on the side portion of the first ceiling surface 3a1 of the second floor portion 3 described above. The detailed description of the configuration will be omitted.

  In the building 1 of the present invention, as shown in FIG. 1, for example, it is provided between the overhanging portion 10 provided on the ceiling surface 3a of the second floor portion 3 and the second ceiling surface 3a2 and on the ceiling surface 2a of the first floor portion 2. The lighting system S can be arranged between the overhanging portion 10 and the first ceiling surface 2a1. In the illustrated case, since the overhanging section 10 is composed of the first overhanging section 10A and the second overhanging section 10B, the lighting system S is provided in each of the overhanging sections 10A and 10B.

  In this way, by arranging the lighting system S between the overhanging portion 10 and the second ceiling surface 3a2 and between the overhanging portion 10 and the first ceiling surface 2a1, the lighting system S illuminates the ceiling surfaces 2a1, 3a2. The ceiling surface 2a1, 3a2 is less likely to cause a shadow of the overhanging portion 10, and the light projected from the lighting system S toward the ceiling surface 2a1, 3a2 causes the overhanging portion 10 and the ceiling surface 2a1, 3a2 to be separated from each other. It is possible to enhance the aesthetic appearance of the ceiling by creating the expansion of the space in the step portion.

  Since the lighting system S arranged between the overhanging portion 10 and the second ceiling surface 3a2 and the lighting system S arranged between the overhanging portion 10 and the first ceiling surface 2a1 have the same configuration, in the following, The configuration of the illumination system S will be described based on the illumination system S arranged between the overhanging portion 10 and the second ceiling surface 3a2.

  The lighting system S in the building 1 of the present invention has the following configuration. That is, as shown in FIGS. 2 and 3, the lighting system S includes a plurality of lighting fixtures 20.

  These light fixtures 20 have a predetermined light emitting part, such as a rod-shaped LED lamp in which a plurality of light-emitting diodes (LED light sources) are linearly arranged into one unit, or a rod-shaped discharge gas lamp such as a fluorescent lamp or a neon tube. It is a rod-shaped light source formed in a rod shape having a linear length. Note that the lighting fixture 20 is not limited to the above as long as the lighting device 20 has a rod-like shape in which the light emitting portion is linear, and various configurations can be used.

  These luminaires 20 are arranged such that one luminaire (first luminaire) 20 is parallel to the other luminaire (second luminaire) 20 and the other luminaire 20 is parallel to the one luminaire 20. The lighting fixtures 20 are laterally spaced apart from each other, and are arranged in the longitudinal direction so as to overlap each other in a predetermined range. As shown in the figure, when arranging three or more rod-shaped lighting fixtures 20 on the projecting portion 10, the third lighting fixture (third lighting fixture) is arranged on one lighting fixture (first lighting fixture) 20. On the other hand, the light emitting portions are arranged in a straight line at intervals in the longitudinal direction, and the light emitting portions thereof are arranged so as to overlap with the other side in the longitudinal direction of the light emitting portion of the other lighting fixture (second lighting fixture) 20 within a predetermined range. .. That is, the plurality of lighting fixtures 20 are divided into two rows, and one row and the other row are oriented in the longitudinal direction so that the light emitting sections of the lighting fixtures 20 overlap with the light emitting sections of the adjacent lighting fixtures 20 within a predetermined range. They are arranged alternately. When four or more luminaires 20 are provided, the respective luminaires 20 are sequentially displaced in the longitudinal direction in a pattern similar to the above so that their light emitting portions overlap.

  With such a configuration, the plurality of lighting fixtures 20 can be arranged such that the light emitting portions thereof do not form an interval in the longitudinal direction. Thereby, the second ceiling surface 3a2 can be uniformly illuminated by the plurality of lighting fixtures 20.

  The lighting fixture 20 also functions as indirect lighting that illuminates the interior space with the light reflected by the second ceiling surface 3a2.

  As shown in FIG. 2, the lighting fixture 20 can be attached to the upper surface of the overhang portion 10. With such a configuration, the lighting fixture 20 can be placed on the overhanging part 10 when the lighting fixture 20 is mounted on the upper surface of the overhanging part 10, whereby the lighting fixture 20 can be attached to the overhanging part 10. The mounting work can be facilitated.

  The lighting fixture 20 is not limited to the upper surface of the projecting portion 10 and may be configured to be attached to the connecting surface 3a3 or the second ceiling surface 3a2 as long as it is arranged between the projecting portion 10 and the second ceiling surface 3a2. .. In these cases, the wiring of the lighting fixture 20 can be easily drawn into the floor slab 6 to facilitate the installation work of the lighting fixture 20.

  In the above-described configuration, the plurality of rod-shaped lighting fixtures 20 having an arbitrary length can be used, but it is preferable to use those having the same length. Accordingly, the lighting fixtures 20 can be evenly arranged in the respective portions of the overhanging portion 10, and the second ceiling surface 3a2 can be evenly illuminated by the plurality of lighting fixtures 20.

  Moreover, when arranging three or more rod-shaped lighting fixtures 20 on the overhanging portion 10, the light emitting portions of the respective lighting fixtures 20 have a length that overlaps the light emitting portions of the other lighting fixtures 20 at one end side in the longitudinal direction. It is preferable to set the same length as the length overlapping the light emitting portion of the other lighting fixture 20 on the other end side in the longitudinal direction. This makes it possible to equalize the amount of light in the portions where the light emitting portions of the respective lighting fixtures 20 overlap with each other, and to evenly illuminate the second ceiling surface 3a2 with these plurality of lighting fixtures 20.

  When the overhanging portion 10 faces the wall to form the connecting surface 3a3 and the like at the end in the longitudinal direction, among the plurality of lighting fixtures 20 that configure the lighting system S, the lighting fixture 20 that is arranged at the outermost end thereof. It is preferable to arrange the longitudinal end portion of (1) adjacent to the wall of the coupling surface 3a3 or the like. In this case, the distance between the end of the lighting fixture 20 in the longitudinal direction and the wall such as the connecting surface 3a3 is preferably 30 cm or less, more preferably 20 cm or less, even more preferably 10 cm or less, and most preferably. Is less than 5 cm. In this way, by arranging the longitudinal end of the lighting fixture 20 adjacent to the wall of the connecting surface 3a3 or the like, unevenness of light in the end region of the overhanging portion 10 is suppressed, and the aesthetic appearance of the ceiling is improved. It can be increased.

  Note that, as shown in FIG. 3, when the overhanging portion 10 is formed by the first overhanging portion 10A and the second overhanging portion 10B to have a corner portion, each side portion of the overhanging portion 10 has the most corner. The longitudinal ends of the luminaire 20 arranged on the side of the section are preferably arranged adjacent to each other. With such a configuration, even at the corners of the overhanging portion 10, a suitable amount of light is emitted from the lighting fixture 20, thereby suppressing unevenness of light in a region corresponding to the corners of the overhanging portion 10 of the ceiling. You can enhance your aesthetics.

  As shown as a modified example in FIG. 4, when the overhanging portion 10 is formed in a shape having a corner portion, a portion L corresponding to the corner portion of the overhanging portion 10 is bent at a right angle at the central portion in the longitudinal direction. It is also possible to arrange the L-shaped lighting fixture 21 having a letter shape. The L-shaped lighting fixture 21 may have a configuration in which a plurality of LED light sources are arranged and arranged in an L shape. In this way, by arranging the L-shaped lighting fixtures 21 at the corners of the overhanging portion 10, unevenness of light in the region corresponding to the corners of the overhanging portion 10 is further suppressed, and the appearance of the ceiling is further improved. Can be increased.

  The ceiling surfaces 2a, 3a, 4a of the respective layers can be configured by applying wallpaper of various colors and patterns, but as described above, the lighting fixture 20 is provided between the overhanging portion 10 and the second ceiling surface 3a2. In the case where the above is arranged, it is preferable to use a white wallpaper as the wallpaper to be attached to the second ceiling surface 3a2. As the white wallpaper, for example, a white wallpaper, a light beige wallpaper, or the like having a high light reflectance can be adopted. Further, it is more preferable that the white wallpaper is made of a material having gloss. As described above, by using the white wallpaper as the wallpaper to be attached to the second ceiling surface 3a2 illuminated by the lighting fixture 20, the light emitted from the lighting fixture 20 toward the second ceiling surface 3a2 is used. The interior space of the second floor portion 3 can be illuminated more brightly by the lighting fixture 20 by efficiently reflecting the interior space by the 3a2.

  In the case where the lighting fixture 20 is arranged between the overhanging portion 10 and the second ceiling surface 3a2 as described above, the surface is roughened as a wallpaper to be attached to the second ceiling surface 3a2. It is preferable to use the one. As the wallpaper subjected to the rough surface treatment, for example, a wallpaper having a predetermined pattern or a random pattern having irregularities on the surface can be used. By using a wallpaper that has been roughened as the wallpaper to be applied to the second ceiling surface 3a2 illuminated by the lighting fixture 20, the second ceiling surface 3a2 is illuminated by the light emitted from the lighting fixture 20 onto the second ceiling surface 3a2. It is possible to further enhance the aesthetic appearance of the ceiling portion by producing a shade of light corresponding to the rough surface treatment.

  As shown in FIG. 5, the overhanging portion 10 can also be configured to include a hidden wall 10b protruding upward at the outer peripheral edge thereof. In this case, it is preferable that the hidden wall 10b is configured to project upward to at least the same height as the lighting fixture 20 and cover the lateral side of the lighting fixture 20. By providing such a hidden wall 10b, it is possible to prevent the light emitted from the lighting fixture 20 from directly irradiating the indoor space, and to prevent the lighting fixture 20 from being viewed from the indoor space, so that You can enhance your aesthetics. Note that the hidden wall 10b is not limited to the shape shown in the figure, and may have various shapes as long as it covers the sides of the lighting fixture 20 and can produce the above effect.

  The lighting system S having the above-described configuration includes the overhanging portion 10 provided on the ceiling surface 3a of the second floor portion 3 and the second ceiling surface 3a2, and the overhanging portion 10 provided on the ceiling surface 2a of the first floor portion 2 described above.
