  Next, a method for constructing the above-described daylighting apparatus 2 in a building 4 such as a factory, a warehouse, or a store will be described mainly with reference to FIGS. In such a building 4, a folded plate roof 6 in which a plurality of folded plate roof materials 54 are joined together is laid. The folded roof material 54 is laid on a tight frame 81 supported by a beam 79. In the present embodiment, the seam joint portions 52 of the folded plate roof 6 are arranged at the first arrangement interval D1 (for example, about 500 mm).

  When constructing the lighting device 2, first, a substantially circular through hole 82 is drilled at a predetermined position of the folded plate roof 6 using, for example, a core drill or a hole saw (see FIG. 3). The diameter of the through hole 82 is configured to be somewhat larger than the diameter of the cylindrical member 66. Next, the gouge joint portion 52 is accommodated and held in the first mounting recess 42 of the lower base plate 24 so that the insertion opening 40 of the mounting member 16 and the through hole 82 of the folded plate roof 6 are aligned with each other. The base portion 20 is placed on a pair of adjacent mountain portions 84 of the folded roof 6 and fixed to each other using, for example, nails, screws, adhesives, or the like. In this laying state, both side end portions of the base portion 20 protrude somewhat outward from the mountain portion 84 of the folded plate roof 6, and the skirt portion 36 is bent inward to fold the tip portion. It is made to adjoin to the mountain part 84 of the plate roof 6 (refer FIG. 6).

  Thereafter, the cylindrical member 66 to which the diffusion cover member 80 is attached is inserted through the cylindrical portion 28 of the attachment member 16, the insertion opening 40 and the through hole 82 of the folded plate roof 6, and the ring-shaped member 70 is inserted into the cylindrical portion. It attaches to 28 openings. When the cylindrical member 66 is inserted in this way, the inner peripheral portion of the dew condensation preventing elastic member 56 is bent downward to elastically press the outer peripheral surface of the cylindrical member 66, thereby the insertion opening portion. A gap between the peripheral edge of 40 and the cylindrical member 66 is sealed by the dew condensation preventing elastic member 56 (see FIG. 5). After that, the dome member 14 is mounted on the opening of the cylindrical portion 28 so that the stepped portion 18 is placed and fixed on the ring-shaped member 70, and the dome member 14 is attached to the cylindrical portion 28 using a fixing screw 86. (See FIG. 4).

  In the present embodiment, the daylighting device 2 is disposed on the most underwater side of the folded plate roof 6, and the upper goby portion 34 is bent in the direction indicated by the arrow in FIG. Further, a plurality of panel members 90 are laid side by side between the rain retainer 88 provided on the water side above the daylighting device 2, that is, the top of the folded roof 6 and the daylighting device 2 (FIG. 4). And FIG. 5). The panel member 90 is composed of an upper base plate 92, a lower base plate 94, and a plurality of support members 96, like the mounting member 16 of the daylighting device 2, but the upper base plate 92 is not provided with a cylindrical portion. In addition, the lower base plate 94 is not provided with an insertion opening. In the same manner as described above, the gob joint portion 52 is accommodated and held in the first mounting recess 98 of the lower base plate 94, and the panel member 90 is laid on the water side of the daylighting device 2, and for example, using nails, screws, adhesives, or the like. Fix each other. The daylighting device 2 and the panel member 90 are connected to each other by joining the lower goby portion 32 of the daylighting device 2 and the upper goby portion 100 of the panel member 90 together. Further, the skirt portion 102 of the panel member 90 is bent inward so that the front end portion thereof is close to the mountain portion 84 of the folded plate roof 6, and one end portion (downstream end portion) of the skirt portion 102 is connected to the daylighting device 2. It overlaps with the outside of the other end portion (upstream end portion) of the skirt portion 36. Similarly, a plurality of panel members 90 are laid side by side between the rain retainer 88 and the daylighting device 2, and the upper goby portion 100 of the waterside panel member 90 and the lower goby portion 104 of the underwater panel member 90. And connect them together. In addition, the lower goby portion 104 of the panel member 90 on the uppermost side is bent in the direction indicated by the arrow in FIG.

  The interior of the building 4 is illuminated as follows by the daylighting device 2 constructed as described above. The light from the sun introduced through the dome member 14 is reflected on the concave surface side of the condensing reflection plate 76 provided in the dome member 14 when the solar altitude is low, such as at sunrise or sunset, and enters the inside of the cylindrical member 66. When the solar altitude is high, such as during the daytime, the light is guided into the tubular member 66 from the opening of the tubular portion 28. The light thus guided is guided in a predetermined direction (that is, the direction in which the irradiation means 12 is disposed) while being irregularly reflected on the inner surface of the cylindrical member 66, and is emitted from the other end of the cylindrical member 66. Then, the inside of the building 4 is diffused and irradiated through the diffusion cover member 80.

  In the winter season when the outside air temperature is low, the outside air flows into the dome member 14 through the plurality of hairs of the dew condensation prevention tape member 30 and the plurality of air inflow recesses 74, thereby increasing the internal temperature of the dome member 14. The temperature difference from the outside air temperature is reduced, and condensation is prevented from occurring inside the dome member 14. In addition, since the space between the peripheral edge of the insertion opening 40 and the tubular member 66 is sealed by the dew condensation preventing elastic member 56, the warm air inside the building 4 is transferred to the tubular portion 28 and the tubular member 66. Inflow is prevented, and condensation is prevented from occurring in the tubular member 66, the dome member 14, or the like.

  As shown in FIG. 7, when the gouge joints 52 of the folded plate roof 6 are arranged at the second arrangement interval D <b> 2 (for example, about 333 mm), the gouge joints are formed in the second mounting recesses 44 of the lower base plate 24. 52, the base portion 20 of the attachment member 16 is placed on the three adjacent mountain portions 84 of the folded plate roof 6, and the attachment member 16 can be attached to the folded plate roof 6 in the same manner as described above. it can. In such a case, the skirt portion 36 extends outward and obliquely downward along the inclined surface of the mountain portion 84 of the folded plate roof 6.

  As described above, in the daylighting device 2 of the present embodiment, when the goby joint portion 52 is arranged at the first arrangement interval D1, the gouge joint portion 52 is accommodated and held in the first mounting recess 42. The attachment member 16 is attached to the folded plate roof 6. Further, when the goby joint portion 52 is arranged at the second arrangement interval D <b> 2, the attachment member 16 is attached to the folded plate roof 6 by accommodating and holding the gouge joint portion 52 in the second attachment recess 44. Therefore, even if the size of the folded plate roof 6, that is, the arrangement interval of the seam joint portions 52 is different depending on the building 4 in which the lighting device 2 is constructed, the mounting member 16 can be easily aligned with the folded plate roof 6. Therefore, the insertion opening 40 of the attachment member 16 and the through hole 82 of the folded plate roof 6 can be easily matched. Therefore, the construction time can be shortened and the lighting device 2 can be easily constructed.
