  A lighting device 65 (65B, 65C) is attached to each of the wall plates 77B, 77C. A plurality of lighting devices 65B and 65C are arranged at predetermined intervals (for example, at equal intervals) in the longitudinal direction of the wall plates 77B and 77C (in other words, the longitudinal direction of the ceiling beams 22B and 22C). A wiring 66 is connected to each of the lighting devices 65B and 65C. These wirings 66 are guided to the inter-beam gap 83 between the ceiling beams 22B and 22C through the wiring holes 77a formed in the wall plates 77B and 77C and the wiring holes 22a formed in the webs of the ceiling beams 22B and 22C. It is. These wiring holes 77a and 22a are provided for the respective lighting devices 65B and 65C (wiring 66). Note that only one wiring hole 22a of the ceiling beams 22B and 22C may be formed, and each wiring 66 may be led to the inter-beam gap 83 through the common wiring hole 22a. In this case, the inter-beam gap 83 is an arrangement space for arranging the wiring 66.

  Each lighting device 65B is disposed between the extending portion 75a of the light shielding plate 75 and the ceiling surface material 27B. Thereby, each illuminating device 65B is covered from the downward direction by the extension part 75a. Each lighting device 65C is disposed between the extending portion 75b of the light shielding plate 75 and the ceiling member 27C. Thereby, each illuminating device 65C is covered from the lower part by the extension part 75b, respectively.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  Ceiling members 27B and 27C whose lower surfaces are set higher than the lower surfaces of the ceiling beams 22 are provided on the ceilings of the building units 20B and 20C, so that the lower surfaces of the ceiling beams 22 below the ceiling members 27B and 27C. A high under-ceiling space 57 was formed at a higher position. The lighting device 65 is installed using the space 57 under the high ceiling, and the light shielding plates 71, 73, and 75 are provided below the lighting device 65. In this case, when constructing indirect illumination with the illumination device 65 and the light shielding plates 71, 73, 75, the feeling of pressure received from the illumination device 65 and the light shielding plates 71, 73, 75 can be reduced.

  Further, the light shielding plates 71, 73, 75 are received from the light shielding plates 71, 73, 75 because they are arranged at the same height as the normal (normal height) ceiling surface material 27A provided on the lower surface side of the ceiling beam 22A. The feeling of pressure can be further reduced.

  Ceiling beams 25B and 25C are bridged between the upper portions of the pair of facing ceiling beams 22 and a ceiling member 27B is attached to the lower surface side of the ceiling beams 25B and 25C (high ceiling beams). In this case, since the ceiling surface materials 27B and 27C (high ceiling surface materials) can be provided with a relatively simple configuration in which the existing ceiling beam 25 is positioned above the ceiling beam 22, the unit ceiling portion can be provided. It can be said that this is a practically preferable configuration for providing a high ceiling surface material.

  Further, if the ceiling beam 25 is removed from the unit ceiling portion, a high ceiling surface material can be provided, but in that case, the unit ceiling portion (the ceiling beam 22 or the like) may be buckled. In that respect, according to the above-described configuration in which the ceiling beams 25B and 25C are positioned above the ceiling beam 22, the high ceiling surface material is provided while preventing the unit ceiling portion from buckling by the ceiling beams 25B and 25C. It becomes possible.

  The ceiling beams 25B and 25C spanned between the pair of ceiling beams 22 are all high ceiling beams, and the ceiling material 27B is provided on the lower surface side of each of the ceiling beams 25B and 25C. 27C (high ceiling surface material) was attached. In this case, the high under-ceiling space 57 can be formed in a wide range in the ceiling of the building units 20B and 20C. Can be increased. Therefore, for example, it is possible to arrange a plurality of illumination devices 65 along the longitudinal direction of the ceiling beam 22 (on the long side), thereby constructing indirect illumination along the longitudinal direction.

  A lighting device 65 is provided at a step between the ceiling members 27B and 27C and the lower surfaces of the ceiling beams 22B and 22C. Specifically, wall plates 62 and 77 are provided at the stepped portions, and the lighting device 65 is attached to the wall plates 62 and 77. In this case, as compared with the case where a hanging wall extending downward from the ceiling members 27B and 27C is provided and the lighting device 65 is attached to the hanging wall, the structure can be simplified to the extent that the hanging wall is unnecessary.

  Further, since the wiring 66 of the lighting device 65 is disposed in the inter-beam gaps 68 and 83 between the facing ceiling beams 22, the inter-beam gaps 68 and 83 that tend to be dead spaces can be effectively used as the wiring space.

  The lighting device 65 is installed in the vicinity of the ceiling beams 22B and 22C in the high ceiling space 57, and a light shielding plate 75 that covers the lighting device 65 from below is attached to the lower surfaces of the ceiling beams 22B and 22C. In this case, the configuration can be simplified as compared with the case where a hanging wall extending downward from the ceiling members 27B and 27C is provided and a light shielding plate is attached to the lower surface of the hanging wall.

  In the ceiling portion of the living room 16 formed across the adjacent building units 20B and 20C, the lighting device 65 is installed in the vicinity of the facing ceiling beams 22B and 22C of both the building units 20B and 20C, and the ceiling beams 22B. A light shielding plate 75 is attached to the lower surface of 22C. In this case, indirect illumination can be constructed under the ceiling on the center side of the living room 16. In addition, since the light shielding plate 75 is attached by using the ceiling beams 22B and 22C at the unit boundary portion, when constructing indirect illumination on the center side of the living room 16 away from the wall (for example, the outer wall 31). The drooping wall can be dispensed with, and the configuration can be simplified.

  Specifically, in the ceiling portion of the living room 16, high ceiling lower spaces 57 are respectively formed on both sides of the facing ceiling beams 22B, 22C of the adjacent building units 20B, 20C, and the respective high ceiling lower spaces 57 are formed. , Lighting devices 65 were installed in the vicinity of the ceiling beams 22B and 22C, respectively. And the light-shielding plate 75 was attached to the lower surface side of each ceiling beam 22B, 22C so that the illuminating device 65 of these both high ceiling lower space 57 might be covered from the downward direction. In this case, indirect lighting is constructed in the vicinity of the ceiling beams 22B and 22C in each of the high ceiling spaces 57, so that it is possible to illuminate the living room 16 over a wide range from the central side toward the peripheral side by the indirect lighting. It becomes.

  As described above, when the indirect illumination is constructed under the ceiling of the living room 16, the light shielding plates 71, 73, and 75 are arranged at the same height position as the normal (normal height) ceiling member 27A. The following incidental effects can be obtained.

  Since the light shielding plate 71 is disposed at the same height as the ceiling member 27 </ b> A, the storage door 37 including a full height door can be installed in the opening 36 of the storage chamber 18. Thus, when the storage door 37 is opened, the opening 36 is opened with a height dimension from the floor surface 44 to the ceiling surface 52. Therefore, when storing the article in the storage chamber 18, the article is placed near the ceiling of the storage chamber 18. Can be easily stored.

  Since the light shielding plate 73 is disposed at the same height as the ceiling member 27A, the vertical dimension from the upper end of the window 32 to the light shielding plate 73 is ensured on the inner surface of the outer wall 31 as usual. As a result, the curtain box 46 can be disposed above the window 32 on the inner surface of the outer wall 31. In addition, a fan coil unit type air conditioner may be arranged on the inner surface of the outer wall 31 above the window 32 instead of the curtain box 46.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, the illumination devices 65B and 65C are attached to the wall plates 77B and 77C. However, for example, the illumination devices 65B and 65C may be attached on the light shielding plate 75 as shown in FIG. In FIG. 6, the illumination device 65 </ b> B is attached on the extending portion 75 a of the light shielding plate 75, and the illumination device 65 </ b> C is attached on the extending portion 75 b of the light shielding plate 75. In this case, it is possible to make the illumination devices 65B and 65C less visible from the bottom of the ceiling as compared with the case where the illumination devices 65B and 65C are attached to the wall plates 77B and 77C. Therefore, the extension length of the extension parts 75a and 75b of the light shielding plate 75 can be made shorter than that in the above embodiment.

  (2) In the above embodiment, the lighting device 65 is disposed in the vicinity of the ceiling beam 22, but the lighting device 65 may be spaced from the ceiling beam 22 as shown in FIG. 7. In this case, the extension length of the light shielding plate 91 extending from the ceiling beam 22 may be increased by the distance of the lighting device 65.

  Moreover, in the example of FIG. 7, it is comprised with the ceiling surface material which consists of a gypsum board on which the light shielding plate 91 was piled up two sheets. The light shielding plate 91 is provided across the lower surfaces of the field edges 47A and 47B fixed to the lower surfaces of the ceiling beams 22A and 22B of the adjacent building units 20A and 20B. It is fixed with screws. And each lighting apparatus 65 is covered from the downward direction by the extension part 91a extended from the ceiling large beam 22B in the light-shielding plate 91. FIG. In this case, since the light shielding member is configured using the ceiling surface material, the number of components can be reduced by the amount that the light shielding member is not provided separately.

  (3) In the above embodiment, the lighting device 65 is disposed in the vicinity of the ceiling beam 22. However, the lighting device 65 may be disposed separately from the ceiling beam 22 by changing this. For example, it is conceivable that the lighting device 65 is disposed in the central portion (in other words, the central portion of the high-ceiling space 57) between the opposing ceiling long beams 22B (on the long side) of the building unit 20B. In this case, since the lighting device 65 and the light shielding plate cannot be attached using the ceiling beam 22B, for example, a hanging wall is provided on the lower surface side of the ceiling surface material 27B, and the lighting device 65 and the light shielding plate are attached to the hanging wall. Will be attached. Also in this case, since the lighting device 65 can be installed using the space under the high ceiling 57, the feeling of pressure received from the lighting device 65 can be reduced.

  (4) In the above embodiment, all the ceiling beams 25B, 25C of the building units 20B, 20C are high ceiling beams, so that the ceiling surface materials 27B, 27C of the building units 20B, 20C are all high ceiling materials. However, only a part of the ceiling beams 25B and 25C among the ceiling beams 25B and 25C may be used as high ceiling beams, and only a part of the ceiling members 27B and 27C may be used as high ceiling members. Even in that case, since a space under the high ceiling is formed below the high ceiling surface material, if the lighting device 65 is installed using the space, the feeling of pressure received from the lighting device 65 may be reduced. it can.

  (5) In the above embodiment, the ceiling beams 25B and 25C are bridged between the upper portions of the pair of opposed ceiling beams 22B and 22C, and the ceiling members 27B and 27C are attached to the lower surfaces of the ceiling beams 25B and 25C. Thus, although the high ceiling surface material (ceiling surface materials 27B and 27C) is disposed, the configuration for disposing the high ceiling surface material is not necessarily limited thereto. For example, a plurality of long materials are bridged at predetermined intervals on adjacent (normally high) ceiling beams 25 (that is, ceiling beams 25 arranged at the same height as the ceiling beam 25A), You may make it arrange | position the high ceiling surface material (ceiling surface material 27) by attaching the ceiling surface material 27 to the lower surface of a scale material. Even in that case, a space under the high ceiling can be formed below the high ceiling member between the adjacent ceiling beams 25.

  Moreover, instead of bridging the long shape between the adjacent ceiling beams 25, a plurality of long materials are bridged between the adjacent floor beams 26 of the building unit 20 of the second floor portion 15, and these long materials. You may attach the ceiling material 27 to the lower surface of this. Even in that case, a space under the high ceiling can be formed below the ceiling member 27. Further, in this case, since the ceiling surface material 27 can be arranged at a higher position than when a long material is bridged between the ceiling beams 25, the vertical dimension of the space under the high ceiling can be increased. .

  (6) In the said embodiment, although LED was used as the illuminating device 65, you may use other illuminating devices, such as a fluorescent lamp and an incandescent lamp. Further, as the lighting device 65, a device that can adjust the amount of light or a device that can adjust the color of light may be used.

  (7) In the above embodiment, the lighting device 65 (corresponding to the equipment) is installed using the high ceiling space 57 of the living room 16, but the acoustic device (speaker or the like) or the like is used using the high ceiling space 57. Equipment equipment other than the lighting equipment 65, such as video equipment (television etc.), communication equipment (transceiver), etc. may be installed. In addition, when installing equipment using the high ceiling space 57, the entire equipment does not necessarily have to be arranged in the high ceiling space 57, and only part of the equipment is in the high ceiling space 57. Equipment equipment may be installed to be arranged. Even in that case, it is possible to reduce the feeling of pressure received from the equipment when installing the equipment.

  Moreover, in the said embodiment, although the illuminating device 65 was attached to wall board 77B, 77C provided in the level | step-difference part between the ceiling surface materials 27B and 27C and the lower surface of ceiling large beams 22B and 22C, for example, this wall board You may provide the blower outlet which blows off the air-conditioning air (cold air or warm air) supplied from an air conditioner to 77B and 77C toward the living room 16. In this case, since the conditioned air can be blown out to the side, the wind blown from the conditioned air (air conditioned air) can be prevented from directly hitting the occupant, which gives the resident discomfort. Can be suppressed.

  (8) In the above embodiment, the flat light shielding plates 71, 73, and 75 are used as the light shielding member, but the configuration of the light shielding member is not necessarily limited thereto. For example, as the light shielding member, a member provided with an upright plate portion standing upward at the tip of the light shielding plates 71, 73, 75 may be used. In this case, the illumination device 65 can be made less visible from under the ceiling.

  (9) For example, in the ceiling surface materials 27B and 27C of the living room 16, an uneven portion may be provided on the lower surface side thereof, thereby improving the design (designability) of the ceiling portion. In that case, among the concave portions and convex portions provided on the lower surface side of the ceiling surface materials 27B and 27C, the convex portions are provided so as to protrude downward, but the ceiling surface materials 27B and 27C are normal ceiling surfaces. Since it is at a position higher than the material 27A, it is possible to reduce the feeling of pressure received from the convex portion.

  Further, a translucent panel that diffuses transmitted light (for example, milky white) may be provided in the ceiling portion of the living room 16 at the same height as the normal ceiling surface material 27A. In that case, since the light from the illumination device 65 is diffused when passing through the translucent panel, so-called surface illumination can be realized in the ceiling portion of the living room 16. In this case, instead of indirect illumination, the illumination device 65 may be attached below the ceiling surface 55 for direct illumination.

  Furthermore, system ceiling conversion may be performed by using the space 57 under the high ceiling of the living room 16.
