DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system ceiling.

[0002]

2. Description of the Related Art In general, a system ceiling is configured such that a ridge is attached to a ridge receiver suspended from the lower surface of a slab of an upper floor by hanging bolts and the like, and a ceiling plate is supported by the ridge. 2. Description of the Related Art When a device such as a lighting device or a ventilation device is mounted on a system ceiling, the device has been fitted and fixed in a mounting opening formed in a ceiling plate.

[0003]

However, in the conventional example described above, not only is it necessary to process the ceiling plate when mounting the equipment, but also it is necessary to install a special support beam or the like for supporting the equipment. For this reason, there is a disadvantage that the installation workability is extremely poor.

The present invention has been made to solve the above-mentioned drawbacks, and has as its object to provide a system ceiling with good installation workability.

[0005]

According to the present invention, there is provided the above object.
Is a franc whose cross section is approximately inverted and extends outward from each side edge.
A frame structure is formed by connecting a plurality of ceiling bars, which support a side edge of a ceiling plate to the flange and incorporate devices such as a sprinkler, in a cross-girder shape. A system ceiling in which the body is supported by suspension bolts suspended from the lower surface of the upper floor slab, and a ceiling plate is supported in a lattice of the frame structure, wherein the ceiling bar is radiated from lattice points. This is achieved by providing a system ceiling incorporating lighting fixtures.

[0006] Further, devices to be incorporated in the ceiling bar 2 are arranged at a position other than the center position of the ceiling bar 2, and a ceiling rail 7 is fixed to the center position, and a partition wall is formed by the ceiling rail 7. 8 can be configured to support the upper end.

[0007]

In the present invention, the ceiling surface is formed by supporting the frame structure 3 with hanging bolts 4 suspended from the lower surface of the slab on the upper floor.
It is performed by supporting. Equipment such as the sprinkler 1 can be incorporated into the ceiling bar 2 that constitutes the frame structure 3, and can be processed into the ceiling plate 5 or the like.
The need for supporting beams for special equipment is eliminated.

Further, according to the second aspect of the present invention, the equipment incorporated in the ceiling bar 2 is arranged at a portion other than the center position, and the center position is used as an installation space for the partition wall 8.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIGS. 1 and 2 show an embodiment of the present invention. In the drawings, reference numeral 2 denotes a ceiling bar made of a channel material having a substantially inverted U-shaped cross section, and a hanging bar suspended from the lower surface of an upper slab. It is supported by the tip of the bolt 4 and disposed so as to partition the ceiling into a rectangular shape. In each of these lattices, a ceiling plate 5 is fitted to form a ceiling surface, and in this embodiment, a sprinkler 1, a smoke detector 9, and a lighting fixture 6, which will be described later, are installed using a ceiling bar 2. A speaker 10 is installed on the ceiling plate 5.

FIG. 3 and FIG. 4 show a state in which the ceiling bars 2 are supported.
1, and the fixing plate 11 is fixed to a mounting bracket 12 such as a crescent fitting mounted on the lower end of the suspension bolt 4. A cover member 13 having a square shape in plan view is provided on the lower surface side of the connection portion of the ceiling bar 2.
Are fixed by screws 14 or the like, and the fixing plate 11
Is obscured. The bolt insertion hole 15 of the mounting bracket 12 is a long hole, and absorbs an error in the position where the hanging bolt 4 is embedded or the length of the ceiling bar 2.

The ceiling bar 2 has a flange 1 on its side edge.
6, and supports the side edge of the ceiling plate 5 as shown in FIG. In the ceiling plate 5 in this embodiment, a sound absorbing material 18 is adhered to the back surface of a front plate 17, and a locking portion 19 formed at the upper end edge thereof is locked to the flange 16 of the ceiling bar 2. The surface plate 17 and the cover member 13 are dimensioned such that the surface plate 17 and the cover member 13 are in the same plane in the installed state. When four ceiling plates 5, 5,... Are installed in the lattice as in the present embodiment, the hanging metal fittings 20 are arranged at the contact corners in the same lattice, and the ceiling plate 5
Sagging is prevented.

In the present invention, the lighting fixture 6 is installed in a concentrated manner at the connection portion of the ceiling bar 2, and a socket hole 21 of the lighting fixture 6 is formed at an end of the ceiling bar 2 as shown in FIG. At the same time, a screw insertion hole 22 is drilled near the socket hole 21, and the lighting fixture 6 is fixed to the upper surface of the ceiling bar 2 with the socket 23 exposed from the socket hole 21 to the lower surface. Have been.

A louver assembly 24 covers the fluorescent lamp mounted on the socket 23 from below. The louver assembly 24 is formed by arranging a plurality of louvers 26 in a frame 25 in parallel.
It is fixed to the ceiling bar 2 by appropriate means.

In the state where the frame structure 3 composed of the above-mentioned ceiling bar 2 is suspended from the ceiling, the lattice of the lattice-like frame formed near the abutting portion of the ceiling bar 2, that is, the ceiling portion. The lighting fixtures 6 are arranged radially from the point, and the room is evenly illuminated.

On the other hand, the louver assembly 24 of the ceiling bar 2
The equipment plate 27 is fixed to a part other than the part where the ceiling bar 2 is fixed, and the lower surface opening of the ceiling bar 2 is closed. As shown in FIG. 7, the equipment plate 27 is for installing equipment such as the smoke detector 9 or the sprinkler 1, and has a mounting hole 28 or the like corresponding to the equipment to be installed.

FIG. 8 shows a structure of a ceiling portion for partitioning a room having a ceiling surface formed as described above. A rail mounting bracket 29 is fixed to the center of the ceiling bar 2 and the lower end thereof is fixed. The upper end of the partition wall 8 supported by a support device (not shown) is held by a ceiling rail 7 fixed by rail mounting brackets 29.

Although FIG. 8 shows a case where the ceiling rail 7 is fixed via a special rail mounting bracket 29, the ceiling rail 7 can be fixed directly to the equipment plate 27. Further, since it is desirable that the partitioning is performed at an intermediate portion of each lattice due to lighting or arrangement of the devices, each device is installed at a position deviated from the center of each ceiling rail 7 and is separated from the partitioning wall 8. Interference is prevented.

[0019]

As is apparent from the above description, according to the system ceiling according to the present invention, a frame structure is formed by a ceiling bar into which various devices are incorporated, and the frame structure is supported by hanging bolts. Since the ceiling surface is formed only by supporting the ceiling plate in the lattice of the body, the workability in construction can be greatly improved as compared with the conventional construction method. Further, since the equipment installed on the ceiling surface is incorporated in the ceiling bar, it is not necessary to newly provide a support beam or the like for the equipment, and the mounting workability can be improved.

In addition, since the luminaires are arranged radially from the lattice points of the frame structure, it is possible to evenly illuminate the room.
