The illumination-integrated base structure 1 is provided on the ceiling of a frame (structural frame) (not shown) of a building or the like. The illumination-integrated base structure 1 includes a joist 10, a joist receiver 20 (an example of a rod-shaped member), a ceiling plate 30, a lighting device 40, and a mounting bracket 50 (an example of a bracket).

The joist 10 is a part of the ceiling base material and is an elongated member (bar-shaped member). The joist 10 may be made of any material, such as metal or wood. For example, as shown in FIG. 1, they are arranged in a grid. That is, the joist 10 includes a joist 10A extending parallel to the X direction and a joist 10B extending parallel to the Y direction. The pitch between the joists 10A (the distance in the Y direction) and the pitch between the joists 10B (the distance in the X direction) are arbitrary, but may be, for example, about 900 mm.

In this embodiment, as shown in FIG. 1, the joist 10B is not provided at the location where the lighting device 40 is provided. As will be described later, the lighting device 40 has a function of supporting the ceiling board 30 instead of the ceiling joists 10B.

For example, as shown in FIG. 3, the joist 10 has a hat-shaped cross section and has a flange portion 11 extending in the horizontal direction (the direction within the XY plane). An edge portion of the ceiling plate 30 is placed on the flange portion 11 . In addition, in FIG. 1, the joist 10B is provided for every joist 10A, and the end part (including the flange part 11) of the joist 10B is supported on the flange part 11 of 10A of joists.

The joist receiver 20, like the joist 10, is a part of the ceiling base material and is an elongated member (bar-shaped member). The joist receiver 20 may be made of any material, like the joist 10, such as metal or wood. The joist receiver 20 is supported by a frame (not shown). The joist receiver 20 is hung from the frame by a hanging member 80 and a hanger 82, as shown in FIG. The joist 10 is fixed to the joist receiver 20. - 特許庁For example, the ceiling joist 10 is fixed to the ceiling joist receiver 20 with a screw or the like. In addition, in a modification, the ceiling joist 10 may be hung on the ceiling joist receiver 20 via a hanger (not shown).

The joist receiver 20 is provided for the joist 10A or 10B and extends over the entire extension range of the joist 10A or 10B. In this embodiment, the joist receiver 20 is provided for the Y-direction joist 10B and extends over the entire extension range of the joist 10B.

The cross-sectional shape of the ceiling joist receiver 20 is arbitrary as long as the mounting bracket 50 can be attached to the ceiling joist receiver 20, and may be, for example, C-shaped, H-shaped, I-shaped, or the like. In this embodiment, as an example, the ceiling joist receiver 20 has a hollow rectangular closed cross section. Note that, in a modified example, the joist receiver 20 may be a solid member.

A plurality of ceiling boards 30 are provided so as to fill the grid-like divisions formed by the joists 10 . The ceiling plate 30 is basically supported on the flange portions 11 of the joists 10 corresponding to the edges of each of the four sides. The ceiling plate 30 may be fixed to the flange portion 11 of the ceiling joist 10 with screws or the like. In a modified example, the ceiling plate 30 may be fixed to the ceiling joist 10 with screws or the like, or may be fixed to the ceiling joist receiver 20 with screws or the like. As will be described later, the ceiling plate 30 is supported by the lighting device 40 at the location where the lighting device 40 is provided.

The lighting device 40 is a device that has a light source 430 and generates light. The light source 430 is optionally an LED (Light Emitting Diode), for example. The lighting device 40 is supported by the ceiling joist receiver 20 as will be described later. Therefore, the lighting device 40 is provided in a manner extending in the Y direction between specific adjacent joists 10A. The illumination device 40 has a longitudinal direction in the Y direction, and the length in the Y direction substantially corresponds to the pitch (separation distance in the Y direction) between the joists 10A. Therefore, the lighting device 40 has a length in the longitudinal direction substantially equal to the length of one side of the ceiling plate 30, and has a relatively large size.

In the example shown in FIG. 4 , lighting device 40 includes main body 41 , module receiving portion 42 , LED module 43 , input terminal block 44 , diffusion panel 45 and trim bracket 60 .

The main body 41 functions as a case and is made of, for example, resin. The main body 41 has a form whose longitudinal direction is the Y direction, and extends in the Y direction. The main body 41 has a U-shaped cross section (cross section viewed in the Y direction) with an open bottom, and has a module receiving portion 42 and an LED module 43 inside.

The module receiving portion 42 supports the LED module 43 . The module receiving portion 42 is fixed to the main body 41 . For example, the module receiving portion 42 is fixed to the main body 41 with rivets 91 . The module receiving portion 42 supports both edges of the LED module 43 in the X direction. The module receiving portion 42 is elastically deformable, for example, and elastically deforms outward in the X direction when the LED module 43 is supported. In this case, the LED module 43 will be attached to the module receiving portion 42 in a detachable manner. Two module receiving portions 42 are provided for one main body 41 . However, the number of module receiving portions 42 is arbitrary. The module receiving portions 42 extend in the Y direction in two rows spaced apart in the X direction.

The LED module 43 has a light source 430 . For example, the light sources 430 form a set of two rows spaced apart in the X direction, and the sets form a plurality of rows spaced apart in the Y direction. The LED module 43 is provided over substantially the entire length of the lighting device 40 in the Y direction. The LED module 43 is provided with respect to the module receiving portion 42 and supported by the module receiving portion 42 .

The input terminal block 44 is provided with terminals and the like for supplying power to the LED module 43 .

A diffusion panel 45 is provided to cover the opening on the lower side of the main body 41 . The diffusion panel 45 diffuses and transmits the light from the light source 430 .

The trim fittings 60 are provided on both sides of the lighting device 40 in the X direction (side portions 410 of the main body 41). The trim fitting 60 is a member elongated in the Y direction, and is provided over substantially the entire length of the main body 41 in the Y direction. The trim fitting 60 has a T-shaped cross section when viewed in the Y direction, and is fixed to the side portion 410 of the main body 41 by rivets 92, for example. In the example shown in FIG. 4, the trim metal fitting 60 is attached to the main body 41 in such a manner that the lower end surface of the side portion 410 of the main body 41 abuts on the corner portion of the trim metal fitting 60 (the corner portion of the T-shaped cross section). Fixed.

The trim fitting 60 forms a receiving portion 62 (flange portion) extending laterally from the side portion 410 of the main body 41 . The receiving portion 62 extends in the horizontal plane (XY plane) and has a function of supporting the ceiling panel 30 . That is, the receiving portion 62 has the same function as the flange portion 11 of the ceiling joist 10, and eliminates the need for the ceiling joist 10 at the location where the lighting device 40 is provided.

Further, the receiving portion 62 preferably extends within substantially the same plane (XY plane) as the flange portion 11 of the joist 10 . In this case, the edge of the ceiling plate 30 is supported at substantially the same height by the receiving portion 62 of the trim fitting 60 and the flange portion 11 of the ceiling joist 10, and the appearance is good.

In addition, the trim fitting 60 has a portion 63 extending inward (opposite side of the receiving portion 62) from the side portion 410 of the main body 41 in the X direction. It extends in an overlapping manner to the X-direction edge of 45 . Therefore, the trim fitting 60 also has a function of preventing the diffusion panel 45 from falling.

The trim fitting 60 may be made of any material as long as it has the required strength and rigidity. However, the trim fitting 60 is preferably made of metal. In this case, it is possible to effectively prevent the light from the light source 430 from leaking from the side portion 410 of the illumination device 40 .

Although only one lighting device 40 is shown in FIG. Although the support structure for one specific lighting device 40 will be described below, the support structure for other lighting devices 40 may be the same.

The mounting bracket 50 integrates the ceiling joist receiver 20 and the lighting device 40 . A plurality of mounting brackets 50 may be provided for one lighting device 40 . In the example shown in FIG. 5 , two mounting brackets 50 are provided for one lighting device 40 .

As shown in FIGS. 6 and 7, the mounting bracket 50 has an upper plate portion 51, a side plate portion 52, and a flange portion 53, and has a hat-shaped cross section when viewed in the Y direction.

The upper plate portion 51 covers the upper portion 21 of the joist receiver 20 . The upper plate portion 51 abuts along the upper surface of the upper portion 21 of the joist receiver 20 . However, a slight gap may be set between the upper plate portion 51 and the upper portion 21 in the vertical direction.

The side plate portion 52 extends downward from the X-direction end of the upper plate portion 51 and within the YZ plane. The side plate portions 52 cover both side portions 22 of the joist receiver 20 . The side plate portion 52 abuts along the outer surface of the corresponding side portion 22 of the joist receiver 20 . However, a slight gap may be set in the X direction between the side plate portion 52 and the corresponding side portion 22 of the joist receiver 20 .

The flange portion 53 extends outward from the lower end of each side plate portion 52 and within the XY plane. It covers the upper part of the lighting device 40 (the upper part 411 of the main body 41). The flange portion 53 abuts along the upper surface of the upper portion 411 of the main body 41 .

The mounting bracket 50 is fixed to the lighting device 40 at the flange portion 53 . Any fixing method may be used, and for example, screws or bolts may be used. In this embodiment, as an example, the flange portion 53 has a mounting hole 531, and is fastened to the upper portion 411 of the main body 41 of the lighting device 40 with a screw 94 (for example, a pan head machine screw) passing through the mounting hole 531 and a nut 95. be done. 6, the upper portion 411 of the main body 41 is reinforced by a reinforcing plate 70 at a fixed location with the mounting bracket 50. As shown in FIG. The reinforcing plate 70 is provided so as to sandwich the upper portion 411 of the main body 41 from above and below. The upper reinforcing plate 70 is provided so as to be sandwiched between the flange portion 53 of the mounting bracket 50 and the upper portion 411 of the main body 41 in the vertical direction. By providing such a reinforcing plate 70 , it is possible to reduce the weight of the main body 41 and secure the required strength at the fastening portion of the main body 41 of the lighting device 40 to the mounting bracket 50 .

In this embodiment, the mounting bracket 50 is not fixed to the ceiling joist receiver 20, but may be fixed with screws, bolts, or the like. For example, the mounting bracket 50 may have the upper plate portion 51 fixed to the upper portion 21 of the joist receiver 20 .

Thus, in this embodiment, the mounting bracket 50 is integrated with the lighting device 40 , so that the lighting device 40 is substantially directly supported by the mounting bracket 50 on the ceiling joist receiver 20 . At this time, the gravity of the lighting device 40 is supported by the upper portion 21 of the ceiling joist receiver 20 via the upper plate portion 51 of the mounting bracket 50 . As a result, the lighting device 40 can be stably supported without hanging the lighting device 40 from the frame using a separate hanging member (see the hanging member 88 in FIG. 8).

Next, further effects of the illumination-integrated foundation structure 1 according to the present embodiment will be described in comparison with the comparative example shown in FIG.

In the comparative example, as shown in FIG. 8, the lighting device 40A is not directly supported by the ceiling joist receiver 20, but is hung on the frame by a hanging member 88. As shown in FIG. Moreover, since 40 A of illuminating devices are extended in the extension range of the ceiling joist 10, the ceiling joist 10 is cut|disconnected by the extension range (refer area SC of FIG. 8) of 40 A of illuminating devices.

As described above, in the comparative example, it is necessary to suspend the lighting device 40A from the frame by the suspension member 88 and to manipulate (cut, etc.) the ceiling joists 10 .

On the other hand, according to the present embodiment, as described above, the lighting device 40 can be stably supported by the ceiling joist receivers 20 without being hung from the frame with a hanging member such as the hanging member 88 . Further, according to the present embodiment, as described above, the receiving portion 62 of the lighting device 40 functions as the flange portion 11 of the ceiling joist 10. There is no need to modify the joist 10B. As a result, the ceiling joist 10B itself can be omitted at the location where the lighting device 40 is provided, and cost reduction can be achieved. In addition, it is possible to effectively reduce the weight of the lighting-integrated base structure 1 as a whole.

Moreover, according to the present embodiment, the lighting device 40 can be easily attached along the joist receiver 20 . In addition, since the lighting device 40 is attached along the ceiling joist holder 20, the appearance is good and it is advantageous from the viewpoint of design.

Next, a method for forming (construction method) the lighting-integrated base structure 1 according to the present embodiment will be schematically described.

FIG. 9 is a diagram showing schematic steps of the construction method.

In step S90, the worker assembles the joist 10 and the joist receiver 20. As shown in FIG. That is, the joist receiver 20 is hung from the frame, and the joist 10 is fixed to the joist receiver 20. - 特許庁At this time, the ceiling joist 10 is omitted at the location where the lighting device 40 is arranged.

In step S92, the worker attaches the lighting device 40 to the ceiling joist receiver 20 using the mounting bracket 50 (see FIG. 6).

In step S<b>94 , the operator supports the ceiling plate 30 on the receiving portion 62 of the trim fitting 60 of the lighting device 40 and the flange portion 11 of the ceiling joist 10 . At this time, the ceiling plate 30 may be fixed to the receiving portion 62 and the flange portion 11 with screws or the like.

In this manner, according to the present embodiment, the lighting-integrated base structure 1 can be formed by a simple process that does not require modification of the ceiling joists 10 and the like.

In addition, in the above-described embodiment, the lighting device 40 and the mounting bracket 50 form an example of a lighting device set. In addition, the ceiling joists 20, the ceiling plate 30, and the mounting bracket 50 form an example of the lighting device support structure.

Although each embodiment has been described in detail above, it is not limited to a specific embodiment, and various modifications and changes are possible within the scope described in the claims. It is also possible to combine all or more of the constituent elements of the above-described embodiments.

For example, in the above-described embodiment, the mounting bracket 50 has a hat-shaped cross-section, but it may have other cross-sectional shapes such as a Z-shape or an L-shape. For example, in the modification shown in FIG. 10, instead of the mounting bracket 50, two mounting brackets 50A with L-shaped cross sections are used. In this case, the mounting bracket 50A is fixed to the side portion 22 of the ceiling joist receiver 20. As shown in FIG. Also, although not shown, instead of the mounting bracket 50, a combination of a mounting bracket 50A having an L-shaped cross section and a mounting bracket (not shown) having a Z-shaped cross section may be used. In this case, the mounting bracket with the Z-shaped cross section may be attached to the upper part 21 of the ceiling joist receiver 20, or may be attached to the mounting bracket 50A with the L-shaped cross section. As described above, the mounting bracket is arbitrary as long as the lighting device 40 can be integrated with the ceiling joist receiver 20 with screws, bolts, or the like.

In the above-described embodiment, the ceiling plate 30 is supported by the receiving portion 62 of the trim metal fitting 60 of the lighting device 40 at the location where the lighting device 40 exists, and the ceiling panel 30 at the location where the lighting device 40 does not exist. Although it is supported by the flange portion 11, it is not limited to this. For example, the ceiling plate 30 is supported by the receiving portion 62 of the trim fitting 60 of the lighting device 40 at the location where the lighting device 40 exists, and directly under the ceiling joist receiver 20 at the location where the lighting device 40 does not exist. It may be attached. In this case, the ceiling joists 10 may be omitted at locations where the lighting device 40 does not exist.

In the above-described embodiment, the lighting device 40 is integrated with the ceiling joist receiver 20 by means of the mounting bracket 50. Alternatively, it may be integrated with another rod-shaped member.
