DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. The system ceiling is constructed by connecting the ceiling frame members 1 in a straight line or a cross shape and disposing a ceiling plate 2 between the ceiling frame members 1. FIGS. FIG. 3 shows an embodiment of a system ceiling configured by connecting ceiling frames 1 in a straight line.

The ceiling frame member 1, which is a component of the system ceiling, is made of metal, has a substantially inverted U-shaped cross section, and has a concave groove portion 3 opened downward over the entire length. At the lower part on both sides of the ceiling frame member 1, horizontal pieces 6 project outward. The ceiling frame material 1 having such a configuration is hung from a structural material of a building such as a slab by a hanger 7 and the ceiling frame materials 1 are crossed through a joiner 30 as shown in FIGS. It is connected and arranged.

[0011] In the recessed groove 3 opening below the ceiling frame member 1, equipment members 4 such as a lighting fixture 4a, a partition 4b, an air inlet and an air conditioning outlet are provided. In addition, the ceiling plate 2 is disposed on the portion surrounded by the ceiling frame material 1 or between the ceiling frame materials 1, and the ceiling plate 2 is mounted on the horizontal pieces 6 provided at the lower portions on both sides of the ceiling frame material 1. It is.

By the way, columns and beams of office buildings have spans of 9000 mm, 6400 mm, 6000 mm and 320 mm.
0mm, 3000mm, etc.
The mainstream is 400 mm or 3200 mm. On the other hand, partitions are often installed at intervals between columns, and the smallest unit in the room is 3200 mm × 3200 mm. Therefore, in order to configure the room in units of 3200 mm × 3200 mm, it is necessary to dispose ceiling equipment within 3200 mm × 3200 mm and change the layout of various equipment members 4 if the layout is changed. Therefore, in the present invention, the above-described ceiling frame member 1 is arranged in a straight line or a cross shape according to the module of the building (the reference is set to 3200 mm). Specifically, if the module of the building is 3200 mm, the ceiling frame material 1 is 320
It is connected linearly or crosswise by the joiner 30 every 1600 mm, which is half of 0 mm, and is arranged so that the interval between adjacent linear ceiling frame members 1 is 1600 mm. Then, the lighting fixture 4a, which is the equipment member 4, is disposed in the concave groove 3 of the ceiling frame member 1 located at the center of the 3200 mm × 3200 mm module, and the ceiling frame members 1 on both sides thereof are arranged.
The upper end portion of the partition 4b, which is the equipment member 4, is disposed in the concave groove portion 3 of FIG.

Here, a straight tube type lamp (40 W or 2 W)
0W), the lighting fixture 4a is disposed at the center of the one ceiling frame member 1, and the remaining portions on both sides in the longitudinal direction of the ceiling frame member 1 are the same as the installation space for other various equipment members 4. Become. When a 40W lamp is used, the lighting equipment 4
Since the length of a is 1244 mm, 1600-124
The length of 4 = 356 mm is an installation space for other various equipment members 4. FIG. 4 shows a state in which the lighting fixture 4 a is installed on the ceiling frame material 1. In the figure, 9 is a ballast provided in the lighting fixture 4a, 10 is a reflector, 11 is a socket, and 12 is a lamp. The luminaire 4a is inserted from below into the recess 3 of the ceiling frame member 1 having a downward opening, and is attached to the ceiling frame member 1 from below by screws or other attachment means. Therefore, attachment and detachment can be performed from below. In FIG. 4, the reflector 10 of the lighting fixture 4a is shown.
Is provided between the side end of the ceiling frame member 1 and the inner surface of the ceiling frame member 1, and this slit 13 is a slit for air-conditioning suction.

FIGS. 5 to 7 show the mounting of the partition 4b. The module of the partition 4b is 800 mm, which is half of the module 1600 mm on the ceiling, and the stud 14 and the panel 15 are installed every 800 mm. The connection between the ceiling frame member 1 and the partition 4b is made via a ceiling rail 16. The ceiling rail 16 has a narrow groove 19 at the upper part and a narrow groove part 1 at the lower part.
9 and a continuous wide groove 20, and lower horizontal pieces 21 are provided on both sides of the lower end of the wide groove 20. Then, a ceiling rail 16 as shown in FIG. 7 is fitted into the concave groove portion 3 opened at the lower part of the ceiling frame member 1, and a screw is inserted into a hole 17 provided on the upper surface of the ceiling rail 16 from the room side to thereby insert the ceiling frame member. 1 is attached to the ceiling frame member 1 from the indoor side by screwing into holes 18 provided on the upper surface of the ceiling frame 1. This ceiling rail 1
6, the upper end of the stud 14 is fitted into the narrow groove 19, and the upper end of the panel 15 on both sides is disposed between both sides of the stud 14 and the wide groove 20.

Sprinkler head 5a, various sensors 5
b, small equipment members 5 such as a speaker 5c, an emergency lighting device 5d, and a downlight are disposed at a connecting portion or a cross portion of the ceiling frame 1. In this case, the small equipment member 5 is mounted using a mounting plate 21 as shown in FIG. The mounting plate 21 includes a main mounting plate 21a or a sub-mounting plate 21b, and a fixing piece 22 protrudes upward at an end. As shown in FIG. 8, cut-and-raised portions 23 project from both ends of the ceiling frame material 1 toward the concave groove portion 3 side.
3, the insertion pieces 25 on both sides of the mounting bracket 24 are inserted and inserted, and the fixing piece 22 of the mounting plate 21 is attached to the mounting bracket 24 by screws 26. The sub-attachment plate 21b is attached to only one of the ceiling frame members 1 at the straight portion or the cross portion of the ceiling frame member 1 as described above, and the main attachment plate 21a is attached to the straight or cross portion of the ceiling frame member 1. In this embodiment, both ends are attached to the ends of two ceiling frame members 1 adjacent to each other in a straight line as described above. Although not shown in FIG. 8, the sprinkler head 5a,
Small equipment members 5 such as various detectors 5b, speakers 5c, emergency lighting fixtures 5d, and downlights are attached. FIGS. 2 and 3 show a state in which the small equipment member 5 is disposed at the connecting portion or the cross portion of the ceiling frame 1 as described above. FIG. 9 shows an embodiment in which a sprinkler head 5a, a sensor 5b, a speaker 5c, and an emergency lighting device 5d are mounted on a mounting plate 21, respectively. Here, if a cable 31 such as a power supply is provided with a through hole in the upper surface of the joiner 30 and is taken out from the through hole, the small equipment member 5 can be attached and detached from the indoor side.
