  First, the whole building to which the lighting device 1 of the present embodiment is attached will be described. The building to which the lighting device 1 of this embodiment is attached is, for example, a two-layer industrialized house having a steel frame structure, and is composed of a reinforced concrete foundation fixed to the ground and structural members such as columns and beams. It has a constructed frame and is composed of a steel-structured superstructure fixed to the foundation. Note that the structural members constituting the frame of the upper structure are standardized (standardized) in advance, and are manufactured at a factory and assembled at a construction site.

  The column of the upper structure is constituted by, for example, a seamless (not having a seam in a horizontal section) rectangular steel pipe. Bolt holes are drilled at predetermined positions on the side surfaces of the columns to form beam joints to which the large beams are joined. The large beam connecting adjacent columns is made of, for example, H-shaped steel, and at both ends of the H-shaped steel, there are joined plates having bolt holes drilled at positions corresponding to bolt holes formed in the beam joints of the columns. Welded. The beam joint and the joining plate are rigidly joined with a high-strength bolt, thereby joining the column and the large beam.

  An outer wall 5 described later is attached around the frame. The outer wall 5 is comprised by arrange | positioning the outer wall panel which consists of an ALC (lightweight cellular concrete) panel, for example. On the inner side (indoor side) of the outer wall 5, for example, phenol foam panel-like heat insulating materials and interior materials such as gypsum board are disposed.

  As shown in FIGS. 1 and 2, an opening such as a window is formed in the outer wall 5 of the building. For example, a sash frame 100 is fixed in the opening, and the sash frame 100 can be opened and closed including a glass plate. A sliding window 50 is provided.

  Hereinafter, the daylighting apparatus 1 of the present embodiment will be described. As shown in FIGS. 1 and 2, the daylighting apparatus 1 of the present embodiment is attached to a position on the outside (outdoor side) of the sash frame 100 installed in the opening formed in the outer wall 5 of the building described above. Yes. The sash frame 100 is installed along the opening inner surface of the opening formed in the outer wall 5. In FIG. 1, only the upper frame portion 101 and the lower frame portion 102 of the sash frame 100 are shown for convenience of explanation. Further, in FIG. 1, for convenience of explanation, only a portion of the outer wall 5 positioned above the upper frame portion 101 and a portion positioned below the lower frame portion 102 are shown.

  Here, the upper side 100 a of the sash frame 100 means a horizontal line constituting the upper end of the upper frame portion 101, and the lower side 100 b of the sash frame 100 means a horizontal line constituting the lower end of the lower frame portion 102. . Further, in a front view of the sash frame 100 as viewed from the outside of the outer wall 5, the vertical line constituting the left end of the left frame portion (not shown) located on the left side is referred to as the left side, and the right frame portion (not shown) located on the right side. The vertical line constituting the right end of the figure is called the right side. The sash frame 100 forms a rectangular or square outer edge by the upper side 100a, the lower side 100b, the left side, and the right side when viewed from the outside of the outer wall 5.

  As shown in FIGS. 1 and 2, the daylighting device 1 according to the present embodiment is fixed to a wall-mounted member 4 attached to the outer wall 5 via a bracket 2 and a hanging tool 3. It is attached.

  The daylighting device 1 is for taking outdoor light indoors through an opening formed in the outer wall 5 of the building. The daylighting apparatus 1 includes a plate-like mirror member 10 that is arranged at a position outside (outdoor side) of the opening of the outer wall 5 and reflects outdoor light toward the opening. The mirror member 10 reflects the sky light that goes vertically downward along the outer wall 5 of the building. Thereby, reflected light can be taken in indoors through an opening part. 1 and 2, the sliding window 50 is provided in the opening of the outer wall 5. However, since the sliding window 50 includes a glass plate, when the sliding window 50 is in an open state, In the closed state, the reflected light can be taken indoors through the glass plate directly from the opening.

  As shown in FIG. 3, the mirror member 10 is formed of a core material 31 made of a hard resin material such as polyethylene or nylon, and a metal material such as aluminum, titanium, or stainless steel. A substrate member 11 having a first surface material 32 and a second surface material 33 laminated and bonded by welding, and one surface of the substrate member 11, specifically, the first surface material 32 with an adhesive layer 34 interposed therebetween. And a reflecting plate member 12 having a reflecting surface 12a having a specular reflectance of 80% or more, preferably 90% or more. As the material of the reflector member 12, aluminum or the like can be used. The core material 31, the first surface material 32, and the second surface material 33 of the substrate member 11 are laminated and integrated. The reflection plate member 12 can be attached to the substrate member 11 by interposing the adhesive layer 34 using the above-described adhesive, for example. However, what is necessary is just to be able to stick the reflecting plate member 12 with respect to the board | substrate member 11, and it is also possible to stick both using a double-sided tape. Further, in order to prevent water and the like from entering between the substrate member 11 and the reflection plate member 12 from the end portion of the bonding interface between the substrate member 11 and the reflection plate member 12, It is preferable to apply a process of attaching a butyl seal or the like to the end of the sticking interface with the reflector member 12, that is, the peripheral end face of the mirror member 10. The “specular reflectance” means regular reflectance, and means the ratio of reflected reflected light (light reflected without being transmitted or scattered) in the irradiated light.

  The reflecting surface 12a is configured by an outer surface of the reflecting plate member 12, in other words, a surface that does not face the first surface material 32. The reflecting surface 12a has a concave curved surface as shown in FIGS. Is formed. More specifically, the mirror member 10 is obtained by bending the substrate member 11 and the reflection plate member 12 itself so that the reflection surface 12a is a concave curved surface. The substrate member 11 and the reflection plate member 12 itself are It is formed in a curved shape along the concave curved surface of the reflecting surface 12a. That is, as shown in FIG. 2, the side view of the entire mirror member 10 has a concave curved shape in which the central part is retracted toward the outdoor side.

  The substrate member 11 of the mirror member 10 of the present embodiment includes a resin core material 31 having a thickness of 7 to 15 mm, a first metal surface material 32 having a thickness of 1 mm or less and a first surface material 32 sandwiching the core material 31. The reflecting plate member 12 of the mirror member 10 of this embodiment is made of metal having a thickness of 1 mm or less. By configuring with such a thickness, it is easy to bend the substrate member 11 alone or in a state where the reflecting plate member 12 is adhered to the substrate member 11, and the substrate member 11 is made of a resin core material. 31 and the first and second surface materials 32 and 33 made of metal, it is possible to realize the mirror member 10 that is lightweight and has high strength. Moreover, since the mirror member 10 has flexibility, when an unexpected stress is applied by a falling object or the like, the mirror member 10 can be prevented from being damaged by being temporarily bent.

  Furthermore, the lighting device 1 according to the present embodiment includes a clamping member that clamps the substrate member 11 and the reflection plate member 12 from both sides in the thickness direction. Specifically, the sandwiching member of the present embodiment includes a bolt 13 that is inserted through the substrate member 11 and the reflection plate member 12 in the thickness direction, and a nut 14 that is screwed into the bolt 13. 11 and the reflecting plate member 12 are clamped using bolts 13 and nuts 14. More specifically, the sandwiching member of this embodiment includes a plurality of nuts 14 that are screwed into the bolts 13 using rod-like dimensioned bolts as the bolts 13. It is clamped between the two nuts 14 in the bolt axial direction. Thereby, the adhesion between the core material 31, the first surface material 32, and the second surface material 33 and the sticking of the reflecting plate member 12 to the substrate member 11 can be maintained and reinforced, and peeling due to deterioration of the adhesive or the like Can be suppressed.

  The substrate member 11 and the reflector member 12 may be sandwiched directly between the plurality of nuts 14 or may be sandwiched between other nuts 14 with another member such as a washer interposed therebetween. Moreover, you may make it clamp the board | substrate member 11 and the reflecting plate member 12 with the head of a volt | bolt and a nut, using a bolt with a head and a nut as a clamping member.

  Moreover, it is preferable that the board | substrate member 11 and the reflecting plate member 12 are bent separately, and are affixed after a bending process. If it does in this way, it will become difficult for a shear stress to act on the sticking surface of the board | substrate member 11 and the reflecting plate member 12 at the time of a bending process, and it can prevent that a shift | offset | difference arises and peels. At this time, since the substrate member 11 and the reflection plate member 12 have flexibility, even if there is a slight difference in the shape (curvature or the like) after the bending process, they can be adapted to each other. Further, the insertion hole 15 formed in the substrate member 11 and the reflection plate member 12 through which the bolt 13 is inserted is formed after the substrate member 11 and the reflection plate member 12 are bent into a concave curved shape and attached. It is preferable. By forming the insertion hole 15 after processing the curved surface, the alignment of the insertion hole 15 becomes unnecessary. In other words, it is possible to prevent the mirror member 10 from being attached with the position of the insertion hole 15 shifted (the bolt 13 is inserted into the insertion hole 15). As a result, in the vicinity of the insertion hole 15 in the mirror member 10. Unnecessary stress is less likely to act.

  Moreover, the bolt 13 of the present embodiment is a cut bolt as described above, and the bolt 13 and the nut 14 of the present embodiment also function as a part of the hanger 3 described later. Specifically, one end portion on the upper end side of the bolt 13 positioned outside the plurality of nuts 14 in the extending direction of the bolt 13 (substantially the same direction as the thickness direction of the mirror member 10) can be connected to a building. A connecting portion 21 is provided. Thus, by making the bolt 13 and the nut 14 function not only as the clamping member but also as the lifting tool 3, the number of parts can be reduced and the manufacturing cost can be suppressed. Details of the hanger 3 will be described later.

  The brackets 2 are formed by bending a thin plate into a crank shape, and are attached to three lower ends of the mirror member 10 of the daylighting apparatus 1 at different positions in the horizontal direction. Specifically, the bracket 2 of the present embodiment is attached to the left end, the right end, and the center of the lower end of the mirror member 10 in a front view from the outside of the sash frame 100, respectively. As for the bracket 2 of this embodiment, the insertion hole is formed in the one end side. The bracket 2 is configured such that the bolt 16 is inserted into the insertion hole of the mirror member 10 and the insertion hole of the bracket 2, and then the mirror member 10 and the bracket 2 are sandwiched between the head of the bolt 16 and the nut 17. It is fixed against. That is, the bolt 16 and the nut 17 of the present embodiment also serve as the clamping member for the substrate member 11 and the reflector member 12 described above.

  The bolt 16 is not limited to a bolt with a head, and a rod-shaped cutting bolt may be used. Between the plurality of nuts screwed to the rod-shaped cutting bolt, the mirror member 10 and the bracket 2 are used. May be inserted.

  In addition, the other end of the bracket 2 of the present embodiment is attached to the lower walled member 42 installed along the lower side 100b on the wall surface near the lower side 100b of the sash frame 100 by the bolt 18 and the nut 19. It is fixed.

  The hanger 3 suspends and supports the upper end portion of the mirror member 10 of the daylighting apparatus 1 from above, and the left end portion and the right end portion of the mirror member 10 in a front view from the outside of the sash frame 100. Three are provided in the central portion and the central portion. Specifically, the hanger 3 of the present embodiment includes a bolt 13 as a rod-shaped member, a lower end side connecting portion 20 that connects the lower end side of the bolt 13 to the upper end portion of the mirror member 10, and an upper end side of the bolt 13. And a connecting portion 21 on the upper end side for connecting the to the building.

  The connection part 20 of this embodiment is comprised by the volt | bolt 13 and the nut 14 screwed together by this volt | bolt 13 as mentioned above. Further, the connecting portion 21 of the present embodiment is constituted by a bracket 23 fixed to the upper end portion of the bolt 13 by a nut 22. An insertion hole is formed in one end portion of the bracket 23, and the bracket 23 is sandwiched between two nuts 22 with one end portion on the upper end side of the bolt 13 inserted in the insertion hole of the bracket 23. The bolt 13 is fixed. As shown in FIG. 2, the other end portion of the bracket 23 is installed on the wall surface in the vicinity of the upper side 100 a of the sash frame 100 along the upper side 100 a by bolts 24 and nuts 25. 41 is fixed. For convenience of explanation, in order to distinguish between the above-mentioned “bracket 2” and “bracket 23”, hereinafter, “bracket 2” will be referred to as “lower bracket 2” and “bracket 23” will be referred to as “upper bracket 23”. To do.

  The walled member 4 is provided with a protrusion 4b extending over the entire length at the center of a rectangular plate 4a, and has a convex cross-sectional shape. The overall length of the walled member 4 is substantially the same as the upper side 100a and the lower side 100b of the sash frame 100. The walled member 4 is provided with two holes 4c through which screws s1 and the like are inserted to be fixed to the outer wall 5 of the building. Here, the hole 4 c is provided at a position that is at least a predetermined dimension from the edge of the opening of the outer wall 4 when the walled member 4 is attached to the outer wall 5. By the way, when a reinforcing bar is arranged inside the outer wall 5, the reinforcing bar may be damaged and a screw may be broken, but the wire diameter, vertical and horizontal pitch of the reinforcing bar must be standardized. Is the majority. For this reason, in the present embodiment, the vertical and horizontal pitches of the two holes 4c are set differently from those of the standardized reinforcing bars. Thereby, even if a screw breakage occurs in one of the two holes 4c, it can be screwed using the other hole 4c.

  The lower bracket 2 is fixed to the lower surface of the protrusion 4 b of the lower walled member 42 of the walled member 4 by bolts 18 and nuts 19. Specifically, as shown in an enlarged circle in the lower left dashed-dotted line in FIG. 2, a long groove 26 extending in the longitudinal direction of the plate 4a is formed on the lower surface of the protrusion 4b. The bottom side (the upper side in FIG. 2) is formed with a width wider than the head of the bolt 18. The long groove 26 has an inlet portion side (the lower side in FIG. 2) that is narrower than the head of the bolt 18 and wider than the threaded portion of the bolt 18. With the long groove 26 having such a configuration, the head of the bolt 18 can be retained in the long groove 26 with the threaded portion of the bolt 18 protruding downward. The lower bracket 2 is attached to the wall by tightening the nut 19 from the front end side of the bolt 18 with the front end side of the bolt 18 protruding from the lower surface of the projection 4b inserted into the insertion hole of the lower bracket 2. It is fixed with respect to the member 42.

  The direction in which the lower bracket 2 is fixed to the walled member 42 may be a direction along the normal line of the outer wall 5, but as in the present embodiment, the direction perpendicular to the lower surface of the protrusion 4 b (the outer wall 5 In the direction orthogonal to the normal line), the fastening member such as a bolt does not interfere with the outer wall 5, so that the thickness of the walled member 42 can be reduced. The fixing of the lower bracket 2 and the walled member 42 is not limited to the bolt 18 and the nut 19 described above, and another fastening member such as a screw can be used.

  Further, the upper bracket 23 is fixed to the lower surface of the protrusion 4 b of the upper walled member 41 among the walled members 4 by bolts 24 and nuts 25. The upper wall member 41 has the same shape as the lower wall member 42 described above, and the fixing method of the upper bracket 23 to the wall member 41 is the same as the fixing method of the lower bracket 2 to the wall member 42 described above. Is the same.

  When attaching the lighting device 1 of this embodiment to a building, first, one walled member 4 (upper walled member 41 in the present embodiment) is attached to the outer wall 5 in the vicinity of the upper side 100a of the sash frame 100. While screwing along the upper side 100a, another walled member 4 (lower walled member 42 in this embodiment) is placed along the lower side 100b with respect to the outer wall 5 in the vicinity of the lower side 100b. And screw. When a screw breakage occurs due to a reinforcing bar arranged inside the outer wall 5, it is possible to perform screwing using another hole 4c provided nearby. Then, the lower bracket 2 and the hanger 3 are fixed to the mirror member 10 of the lighting device 1. Further, the lower bracket 2 is fixed to the lower surface of the protrusion 4 b of the lower wall member 42 by the bolt 18 and the nut 19, and the hanger 3 is used for the upper wall member 41 by using the upper bracket 23. It is fixed to the lower surface of the projection 4b with bolts 24 and nuts 25. Note that the mounting order is an example, and can be appropriately changed in consideration of workability.

  Since the lighting device 1 attached in this way can be attached to the outer wall 5 via the upper bracket 2, the hanger 3 and the walled member 4, the weight of the lighting device 1 is added to the sash frame 100. Absent.

  In addition, when the space | interval from the upper side 100a to the eaves is narrower than the width | variety of the walled member 4, and the walled member 4 cannot be installed, the lower bracket 2 is fixed to the outer wall 5 via the walled member 4. However, the upper bracket 23 may be directly fixed to the outer wall 5. Further, when the distance between the lower side 100b and the ground is narrower than the walled member 4 and the walled member 4 cannot be installed like a ground window, the upper bracket 23 is connected to the outer wall via the walled member 4. The lower bracket 2 may be directly fixed to the outer wall 5 while being fixed to the outer wall 5.

  Moreover, when making the length of the walled member 4 longer than the length of the corresponding side of the sash frame 100 (the length of the upper side 100a and the lower side 100b in this embodiment), the walled member 4 with respect to the outer wall 5 Since the bearing surface area can be increased and the burden on the weight of the daylighting device 1 can be dispersed, the walled member 4 can also be installed at a site where the strength of the outer wall 5 is not so strong.

  On the other hand, when the length of the walled member 4 is excessive, the walled member 4 protrudes greatly from the daylighting device 1, so that the burden on the weight of the daylighting device 1 can be dispersed without deteriorating the appearance design. The length of the walled member 4 is preferably substantially the same as the length of the corresponding side of the sash frame 100 (the length of the upper side 100a and the lower side 100b in this embodiment).

  In the present embodiment, the upper walled member 41 installed along the sash frame 100 on the wall surface in the vicinity of the upper side 100a of the sash frame 100 and the wall surface in the vicinity of the lower side 100b of the sash frame 100 on the sash frame 100. The lower walled member 42 installed along the lower wall 2 is shown. For example, the daylighting apparatus 1 is connected to the lower bracket 2 via the lower bracket 2 without using the hanger 3 and the upper walled member 41. You may make it fix only with respect to the member 42 with a lower wall. However, if the suspension 3 is used together as in the present embodiment, even if a vertical load is applied on the mirror member 10 due to snow or the like, the mirror member 10 is bent and deformed in a desired direction to receive the load. Therefore, the mirror member 10 can be hardly damaged.

  The daylighting apparatus according to the present invention is not limited to this embodiment, and various modifications can be made without departing from the scope of the claims. For example, in the present embodiment, the lower bracket 2 is attached to both the left and right ends and the center of the mirror member 10 in a front view from the outside of the sash frame 100. Accordingly, it may be configured to be attached only to both ends in the left-right direction. Similarly, the hanging tool 3 of the present embodiment may be configured to be attached only to both ends in the left-right direction according to the weight, dimensions, etc. of the daylighting device. Further, in the present embodiment, the bolt 13 and the nut 14 and the bolt 16 and the nut 17 are used as the clamping member, but any other clamping member may be used as long as it can clamp the substrate member and the reflection plate member. It is also possible.
