[0003]

However, in the conventional structures of this type, since the equipments are supported by the ceiling finishing material, it is necessary to give the ceiling finishing material rigidity. There is a problem in that a large amount of the ceiling finishing material is exposed on the ceiling finishing surface and the appearance is impaired.
Further, in a conventional system ceiling of this type, since the installation (locking) mode between the equipment such as lighting equipment and the ceiling panel is different, the compatibility between the ceiling panel and the equipment is poor, and the equipment is connected in a line. However, the equipment line could not be moved. In addition, when the equipment line was changed, it was necessary to newly perform drilling work for the equipment and repair work for the removed part. In particular, there has been a problem that large-scale equipment such as lighting equipment and air-conditioning equipment has to be repaired for the groundwork, so that the work becomes large. In addition, there is also a problem that a separate ceiling inspection port must be provided for maintenance of equipment and equipment, and in particular, it is necessary to remove all ceiling panels when changing large equipment. there were.

The present invention has been made in view of the above circumstances, and provides a system ceiling that enables compatibility between a ceiling panel and an equipment panel to which equipment is attached, and that can improve the appearance of the ceiling surface. It is intended to do so.

[0005]

The equipment panel 20 is attached. A breath metal fitting 30 is provided at an arbitrary position between the ceiling base material 5 and the ceiling finish material 7 (specifically, the center position of each side of the grid portion 9 formed by the ceiling base material 5 and the ceiling finish material 7). It is mounted and horizontal position adjustment is performed.

The ceiling base material 5 is formed of a channel member made of steel, and is clamped by a hook portion 4a of a hook-shaped hanging metal fitting 4 attached to a hanging bolt 3 with a fixing nut 3a. Suspended (Fig. 4

At the lower end of each holding leg piece 6c, an inward holding claw 6f that engages with the hanging piece 7a of the upper horizontal piece 7b of the ceiling finishing material 7 is formed. In order to connect the ceiling base member 5 and the ceiling finishing member 7 orthogonally with the fixing member 6 configured as described above, the fixing member body 6d is straddled from above the ceiling base member 5 and then held on both sides. The holding claws 6f of the leg pieces 6c are engaged with the hanging pieces 7a of the ceiling finishing material 7 to temporarily hold the ceiling finishing material 7 below the ceiling base material 5, and in this state, are fastened to the screw holes 6a of the rectangular base 6b. By screwing the screw 6e, the ceiling base material 5 and the ceiling finishing material 7 can be attracted and fixed (see FIGS. 4, 6, and 7).

As described above, the ceiling base material 5 and the ceiling finish material 7 are connected to each other at right angles to form the ceiling finish material 7,

And equipment such as an air outlet 22, a speaker 23, a sprinkler 24 or a smoke detector 25. At this time, when attaching a relatively heavy object such as the lighting equipment 21, for example, the above-mentioned ceiling finishing members 7, 7 between the two ceiling base materials 5, 5 arranged in parallel are placed between the ceiling finishing members 7, 7. The equipment panel 20 is erected in the same manner as the ceiling panel 10, and the lighting equipment 21 is supported by fixing bolts 71 and nuts 72 attached to the equipment mounting member 70 erected between the ceiling base materials 5 and 5 with the mounting bracket 60.

In this case, as shown in FIG. 14, the mounting bracket 60 has a rectangular mounting base 62 having a screw hole 61 at the center, and an L-shape hanging from diagonal positions at both ends of the mounting base 62. It is composed of a mounting bracket main body 65 composed of support legs 64 having a shape of a circle, and a fastening screw 66 that is screwed into the screw hole 61 of the mounting bracket base 62 from above. In this case, locking claws 63 are provided at the lower ends of the support legs 64 and engage with the lower edge of the ceiling base material 5 toward the inside, respectively. Further, the equipment mounting member 70 has a hat-shaped main body 73 having a central portion protruding upward, and reinforcing ribs 74 protruding from both side edges of the hat-shaped main body 73.
5 is formed.

The equipment mounting member 70 constructed as described above
In order to support the lighting device 21 with the mounting bracket 60 and
As shown in FIG. 14, after the mounting bracket 60 is laid over the equipment mounting member 70 placed on the upper surface of the ceiling base material 5, the mounting bracket 60 is rotated in the horizontal direction and the horizontal of the support legs 64.
