The field edge 7 may be held by a field edge support 6 arranged parallel to the frame 10. The panel device 1 may be provided with the field edge receiver 6, the field edge 7, and the ceiling panel 8.
In the illustrated example, the ceiling panels 8, 8 on both sides of the equipment mounting panel 20 in the second direction are supported by field edge supports 6 arranged parallel to the frame 10, and constitute a ceiling base, and form a field extending in the second direction. It is held by the edge 7. In other words, this is an example in which the edge 7 and edge support 6 from which the ceiling panel 8 is hung and the frame 10 from which the equipment mounting panel 20 is hung are installed separately, so to speak, without depending on each other.

The field edge support 6 and the frame 10 may be held by hanging members 2 arranged at a plurality of locations at intervals in the first direction and the second direction. With such a configuration, the frame 10 that holds the device mounting panel 20 can be held by the general hanging member 2 that holds the field edge support 6. In other words, the hanging member 2 that holds the ceiling panel 8 and the hanging member 2 that holds the equipment mounting panel 20 can be made into a common component. This hanging member 2 may be included in the panel device 1.
The hanging member 2 is screwed into a female threaded member such as an insert provided at a plurality of locations at intervals in a first direction and a second direction on a frame such as an upper slab or a steel frame that serves as a suspension base, and A hanging bolt 3 is provided so as to extend in the vertical direction orthogonal to the two directions.

The upper end of the hook piece 4a has an inclined shape that widens the opening. The hanger 4 is provided above and below the piece to be held, and is fixed to the hanging bolt 3 by being sandwiched between nuts threaded onto the hanging bolt 3. As shown in FIGS. 1 and 6(a), some of the plurality of hangers 4 are attached with brace attachments 5 to which lower ends of braces (not shown) are attached.
The hanging member 2 including the hanger 4 is not limited to the configuration described above, and may be a known hanging member used as a hanging member for a ceiling base of a suspended ceiling, or may have various other configurations.

The field edge supports 6 are elongated in the first direction and arranged at a plurality of locations at intervals in the second direction, and constitute a steel ceiling base (light ceiling base). The field edge receiver 6 may be formed into a groove-shaped steel shape (channel shape) that opens laterally. The field edge receiver 6 may be attached to the hanger 4 by being inserted through the upper opening of the hanger 4 with elastic deformation of the hook piece 4a, and may be fixed with a fixing device such as a screw. The dimension along the vertical direction from the bottom piece of the hanger 4 to the retaining protrusion is approximately the same as the dimension of the field edge receiver 6 along the same direction. The dimension along the second direction between the hanging piece of the hanger 4 and the lower end portion of the hook piece 4a is approximately the same as the dimension of the field edge receiver 6 along the same direction. The steel ceiling base may include a field edge joint that joins the field edge receivers 6, 6 adjacent to each other in the first direction.

The field edges 7 are elongated in the second direction and are arranged at a plurality of locations at intervals in the first direction, and constitute a steel ceiling base (light ceiling base). The field edge 7 surrounds the area where the equipment mounting panel 20 is installed, and extends to at least one side in the second direction of the area where the equipment installation panel 20 is installed and, if necessary, both sides in the first direction. will be distributed. In other words, the equipment mounting panel 20 is held by the frame 10 that is placed in place of the field edge 7 at a location where the field edge 7 is not provided. The field edge 7 may be shaped like a channel steel opening upward, or may have a lip portion formed to be folded back at the upper ends of both side walls. . This field edge 7 may be appropriately held on the field edge support 6 via a known clip. The steel ceiling base may include a field edge joint that joins the field edges 7, 7 adjacent to each other in the second direction. As a ceiling base for holding the ceiling panel 8, instead of such a field edge 7, a so-called T-bar having a flange portion on the lower end on which an end portion of the ceiling panel 8 is placed may be used.

The ceiling panel 8 has a substantially rectangular shape when viewed from above (viewed in the thickness direction). In the illustrated example, the first direction of the ceiling panel 8 is the panel width direction, and the second direction is the panel longitudinal direction.
This ceiling panel 8 is held at each end in the first direction by edges 7, 7 provided at intervals in the first direction.

The dimension of the ceiling panel 8 along the first direction, that is, the width dimension may be a dimension corresponding to the pitch of the edges 7, 7, and may be, for example, about 300 mm to 1200 mm. The dimension along the second direction, that is, the length dimension of this ceiling panel 8 may be about 600 mm to 2000 mm. The thickness of the ceiling panel 8 may be, for example, about 3.0 mm to 20.0 mm.

The frame 10 is suspended and held by the hanging member 2. The frame 10 includes a suspended portion 11 in which insertion holes 14 (see FIG. 1) through which the hook pieces 4a of the hanging member 2 are inserted are provided at a plurality of locations at intervals in the first direction.

The wiring duct 34 is inserted and attached as follows. With such a configuration, various devices such as lighting devices can be attached to the wiring duct 34 attached to the device attachment groove 29 at any position in the first direction. Furthermore, since one wiring duct 34 is attached to the equipment mounting groove 29 of one equipment mounting panel 20, one wiring duct 34 is installed across a plurality of equipment mounting panels 20. Maintainability can be improved compared to other configurations. Further, it becomes possible to easily provide the equipment mounting panel 20 with a function of positioning the equipment mounting panel 20 and the wiring duct 34 and temporarily holding the wiring duct 34, thereby improving workability during construction. Furthermore, the effect of suppressing the total power consumption of a plurality of devices attached to one wiring duct 34 from becoming excessive can be expected.

The connecting member 30 is provided with an opening 33 that communicates between the indoor side and the back side of the ceiling via the wiring insertion part 28 provided in the protrusion 25 of the device mounting panel 20. With such a configuration, various cords such as a power cord, a ground wire, and a communication line on the back side of the ceiling can be connected to the wiring duct 34 through the opening 33 and the wiring insertion portion 28.
