[Prior Art] In a conventional ceiling using a T-bar, as shown in FIG. 10, a hanger 2 is attached to the lower end of a suspension bolt 1 having an upper end fixed to a ceiling slab, and a C-shaped channel 3 is attached to the hanger 2. , 4 are hung in a grid pattern, the upper end of the clip 6 is locked to the channel assembly 5, and the lower end of the clip is T-shaped.
The bars 7 are suspended in parallel with each other, and the ceiling plate 8 is mounted so as to be placed over the T bar.

The lighting fixture 9 is mounted by suspending a pair of supporting T-bars 10 in parallel between the T-bars 7 and placing a lighting cover 9a or the like on it, or by omitting it in the drawing, A pair of supporting T-bars are laid across at a right angle, and are mounted by being placed on it.

[Problems to be Solved by the Invention] In a ceiling using this T-bar, there is a limitation in the arrangement of the lighting fixtures because the lighting fixtures are mounted with the T-bar suspended in parallel as a support. The variation of the lighting equipment in one module was limited, and it was difficult to effectively install the lighting system. In addition, since the above channel assembly is used as an intermediate member for suspending the ceiling, a space for arranging the intermediate member is required between the ceiling slab and the ceiling in addition to equipment space such as an air conditioning duct. Since the ceiling height is only low, there is a problem in the lighting effect.

This invention was conceived in order to solve the above-mentioned conventional problems, and its purpose is to directly suspend the ceiling by omitting the intermediate member that was indispensable for suspending the ceiling, thereby Lighting fixtures and the like can be arranged inside the framework of the T-bars without being influenced by the arrangement of the T-bars for the boards, and the ceiling is directly hung so that the ceiling is provided higher than ever. It is an object of the present invention to provide a ceiling having a new structure capable of improving the lighting effect and reducing the number of steps and the construction cost by omitting the intermediate member.

[Means for Solving the Problems] The present invention based on the above object uses a T-bar having a lower edge formed as a receiving edge, and the T-bar is framed in a square shape with the receiving edge in the same plane, and the T-bar is placed inside the frame. The internal T-bars are arranged in parallel with the framework T-bars to form a compartment inside the framework, and the framework T-bars are held by hanging bolts, and the ceiling T-bars are installed at required locations on the ceiling slab. It is directly hung on the frame, and an external T-bar for mounting the ceiling plate is arranged over the frames to connect the frames to each other.

[Operation] In the above configuration, the rectangular frame by T-bars precedes, and thereafter the external T-bars for ceiling mounting between the frames are arranged. Therefore, in the equipment section partitioned and formed in the frame, You can freely set the layout of equipment such as lighting fixtures, and the variations in the layout are diverse, so you can obtain lighting that suits the size of your room and the height of the ceiling. Also improves.

[Embodiment] FIGS. 1 to 9 show an embodiment of the present invention.

In the figure, 11 is a T-bar that forms a frame 14, 12 is an internal T-bar arranged in a frame inside the frame 14, and 13 is a plurality of frames.
It is an external T-bar for mounting the ceiling plate provided over 14.

As shown in FIG. 4, these T-bars 11, 12, and 13 have lower edges formed on the receiving edges a and upper edges formed on the sandwiching edges b protruding laterally. Further, on the side surface of the T-bar 11, a pair of upper and lower fitting pieces d for receiving the lateral mounting pieces c bent at the respective ends of the inner T-bar 12 and the outer T-bar 13 are formed at predetermined intervals by projection molding. I am doing it.

The frame 14 of the T-bar 11 has a square shape. It is performed by holding the same surface. This hanging bolt
Clips 16 are provided at the lower end of the hanging bolts 16 at four sides of the lighting fixture, provided at required intervals.
The clamping edge b is clipped by 17 and the T-bar 11 is directly suspended in a square shape.

In the illustrated example, the T-bars 11 whose both ends are cut off at the same angle form a square double frame 14, but the frame 14 may be a single frame. The above hanging bolt
16 is preferably provided at the connecting portion between the internal T-bar 12 and the external T-bar 13, and in this case, the frame 14 hangs both the internal T-bar 12 and the external T-bar 13 so as to suspend them directly. be able to.

After performing the construction of the framework 14, the internal T-bar 12 is arranged inside the framework 14 in parallel with the framework T-bar in parallel with the position of the suspension bolt 16 as a guide. This T bar
Of the twelve, one parallel pair extends over the inner T-bar 11 of the framework 12 and has both ends hooked on the sides of the inner T-bar 11 and intersects the inner T-bar 12 while the other parallel pair is engaged. The pair consists of a long one extending over the internal T-bar 12 and an internal T-bar.
It consists of a bar 12 and a short length extending over the inner T-bar 11, and they are hooked to the side of the inner T-bar 11 by using a pair of the inner T-bars 12 in parallel as an intermediate joint.

By disposing this internal T-bar 12, an equipment section 20 having a required space 18 and a corner space 19 is partitioned and formed inside the framework 4 between the framework T-bar 11 and each internal T-bar 12.

After a plurality of the frameworks 14 are directly hung on the ceiling slab 15 at required intervals and the arrangement of the internal T-bars 12 is completed, the frameworks are connected to each other by the external bars 13. External T bar 13
Is hung over the framework on the extension of the internal T-bar 12,
Further, the frame members 14 are connected to the outer T-bars 11 of the frame members 14 by hooking to connect the respective frame members 14 to each other, and the inner T-bar members 12
And form a grid-like ceiling base material.

After the arrangement of the external T-bars 13 is completed, the luminaire 21 is installed in the space 18 of each frame 14, and the corner space 19 is provided with a speaker 23 and a smoke detector as shown in FIG. 6 and subsequent figures. Equipped with 24 etc. After the equipment is completed, the central portion partitioned by the internal T-bar 12 is closed by mounting the ceiling plate 22. Ceiling board over the external T bar 13
22 is hung and the ceiling is completed.

FIG. 5 shows an example of equipment of the lighting fixture 21. The lighting cover 25 is housed in the space 18 and the opening edge is placed on the receiving edge a between the inner T bar 11 and the inner T bar 12 of the frame 14. At the same time, the installation members 26 on both sides of the lighting cover 25 are fitted to the holding edge b to fix the lighting cover 25 together with the ballast 27. As a result, the fluorescent lamp 28 is positioned along the four sides of the framework 14.

6 to 9 show some of the arrangement variations of the luminaire 21 in the equipment section 20, and the arrangement variations can be arbitrarily selected according to the scale of the living room or the purpose of use. Further, as shown in FIG. 9, the lighting fixtures 21 can be arranged in parallel by adding the internal T-bars 12 together.

[Effects of the Invention] The present invention has the following effects because the ceiling is configured as described above.

Unlike the case where the lighting equipment is installed between the ceiling T-bars, the equipment such as the lighting equipment is not restricted by the arrangement of the ceiling bar T-bars, and the arrangement of the lighting equipment is not limited in the framework. Since it can be changed in the street, the variation can be selected according to the scale of the living room, the ceiling height, the purpose of use of the living room, etc. without changing the arrangement of the ceiling plate outside the frame. Therefore, the variety of lighting is increased, the lighting effect is further improved, and it is easy to match the interior decoration.

Since the ceiling is hung directly, the space for arranging intermediate members such as beams for suspension is not required between the ceiling slab and the ceiling can be set higher by the amount that the intermediate members are omitted. The overall weight is reduced and the number of processes is also reduced, resulting in a reduction in construction cost.

Since there is no intermediate member, it is easy to fit the air-conditioning ducts and pipes into the ceiling space, and the ceiling can be made higher than before, so it was installed high even in the living room of a building with a low floor. The ceiling and the lighting within the rectangular frame make the ceiling look good.

Since the frameworks are connected to each other by the external T-bars, the frames can sufficiently withstand the external force from the lateral direction, and a strong ceiling can be formed without suspending the external T-bars on the ceiling slab.
