The upper and lower ends of the ceiling bar main body 3 are provided with ceiling plate holding pieces 2 for holding the ends of the ceiling plate 1 toward the outside. It is provided. The connecting piece 23 that integrally connects the two leg pieces 22 has a recess 5 that opens downward, and has a substantially arched shape in the embodiment shown in the accompanying drawings. The inner surface of the recess 5 that opens downward is the illumination reflection plate portion 4. On both sides of the recess 5 of the ceiling bar main body 3, a wiring recess 11 is formed which is opened upward by the connecting piece 23 and the leg piece 22 which form the recess 5. Since the wiring recesses 11 are provided on both sides of the recess 5, one of them is passed through the weak electric wire 23a as shown in FIG.
On the other hand, the strong electric wire 23b is passed, and by doing so, the ceiling bar A can be used as a passing path for wiring under the ceiling, and the weak electric wire 23a and the strong electric wire 2 can be used.
3b and 3b can be separated and wired.

Illuminator mounting portions 7 are provided on both upper sides of the recess 5 of the ceiling bar body 3. A locking piece 25 that opens downward is provided on the side of the lighting fixture mounting portion 7. Further, in the embodiment shown in the accompanying drawings, the upper end surface of the leg piece 22 and the upper end surface of the lighting fixture mounting portion 7 are at the same level and serve as a contact portion 14 for contacting the ceiling structural member 45. Also,
As shown in FIG. 2, a socket insertion port 6 is provided in the recess of the recess 5 of the ceiling bar body 3.

As shown in FIGS. 3, 4 and 5, the ceiling bar A having the above structure is arranged on the lower surface of the ceiling structural member 45 made of C-channel material or the like so as to be orthogonal to the ceiling structural member 45. Then, the pad 14 is connected to the lower surface of the ceiling structural member 45 by the connecting fitting 26. Here, as shown in FIG. 3, since the four fitting portions 14 are connected to the lower surface of the ceiling structure material 45 by the connecting metal fittings 26, the strength is increased against the twist of the ceiling bar A and the ceiling structure is increased. The connection of the ceiling bar A to the material 45 is stable. The lighting fixture main body 8 is attached from the state shown in FIG. 6 as shown in FIG. Then, the lighting fixture mounting portion 7
As shown in FIG. 8 with the lighting fixture body 8 mounted on the
The hooking piece 28 on the upper portion of the connection fitting 27 having a U-shape is hooked on the hooked portion 29 provided on the lower side portion of the lighting equipment main body 8, and the hooking portion 28 on the bottom of the connection fitting 27 of the lighting equipment mounting portion 7 is hooked.

Further, a socket insertion port 6 is provided in the groove depth of the recess 5 near the longitudinal direction of the ceiling bar main body 3 of the facility opening 30, and the socket insertion port 6 is inserted from above and positioned in the recess 5. Lamp 10 in socket 9
When attached, the end plate 13 of the equipment plate 12 is located near the opposite side of the socket 9 from the lamp 10.
3 also serves as an end plate at the end of the lamp 10. By the way, conventionally, as shown in FIGS. 19 and 20, the end plate 5 of the lighting fixture B provided between the ceiling bars A ″.
Since 0 and the equipment plate 12 'are separate bodies, streaks can be seen in the part indicated by a in FIG. 19 and the appearance is poor, but
The end plate 13 of the equipment plate 12 as in the present invention
When the end plate of the lamp 10 also serves as the end plate, this is not the case.

To attach the equipment plate 12 to the ceiling bar main body 3, for example, as shown in FIGS. 13 and 14, the lower portions of the substantially inverted V-shaped spring members 32 are attached to both sides of the equipment plate 12, and the ceiling is By providing hooking holes 33 on both sides of the equipment opening 30 at the back of the groove of the main body 3, inserting the spring member 32 into the hooking hole 33 and pressing the spring member 32 against the edge of the hooking hole 33. The equipment plate 12 can be attached. Here, when the equipment device 31 such as a speaker, a smoke detector, a heat detector, or a sprinkler is fixed to the equipment plate 12 and the equipment device 31 is tall, the above process is performed. When the equipment plate 12 is attached from below, the equipment 31 is inserted from the bottom into the equipment opening 30 as shown in FIG. 13, and wiring, piping, etc. It is to be inserted.

Here, as shown in FIG. 14, the equipment 3
When 1 is separate from the equipment plate 12, the equipment 31 is fixedly attached to the ceiling bar main body 3 by a fixture such as a screw. Further, in the above-described embodiment, an example in which the edge of the equipment plate 12 is formed into a tank shape on the inner peripheral surface of the recess 5 has been described, but the equipment 31 is separate from the equipment plate 12 as shown in FIG. In case, equipment 31
Is fixed to the ceiling bar body 3 with a fixing tool such as a screw, and the equipment device 31 is inserted into the recess 5 from the equipment opening 30.
The equipment plate 12 may be attached to the equipment 31 by any attachment means so as to wrap the outside of the lower part of the equipment plate 12.
