Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a new method of constructing a ceiling structure used in, for example, an office automation ceiling of an intelligent building.

[0002]

2. Description of the Related Art In recent years, facilities such as air conditioning and disaster prevention have been changed to centralized control type with the increase in construction of a type called intelligent building, and system ceilings have become widespread in order to adapt to it. Among them, the system ceiling structure that is a semi-concealed type, commonly known as the double line construction method, which has been particularly popular in Japan, has a lighting fixture between two generally parallel inverted T-shaped support bars (T bars) arranged in parallel. An equipment plate is arranged, two outer T-bars are arranged at equal intervals on the outside of these two inner T-bars, and air-conditioning is sucked into the evenly-spaced spaces provided between the inner T-bar and the outer T-bar. An outlet is provided. The luminaire is exclusively for the system ceiling and is attached to the inner T-bar with a mounting bracket. The mounting bracket has a height-adjustable structure for mounting the lower end of the reflector flange of the lighting fixture on the inner upper surface of the inner T-bar horizontal flange, and a structure that is mounted on the T-bar head. It is an accessory specification. As for the equipment plate, equipment and the like are set as required, and they are placed continuously in parallel with the lighting equipment inside the inner T-bar horizontal flange. Inside T
Spacers are provided to make the gap between the bar and the outer T bar parallel and uniform. The ceiling material is mounted with its ends on the outside of the outer T-bar horizontal flange.

[0003]

In the equipment line of the so-called double line construction method, which is the conventional ceiling structure, two parallel T-bars are required for arranging the lighting fixtures and equipment plates, and further air conditioning is required. In order to install the outlet / suction port, it was necessary to straighten and fix the two T-bars arranged in parallel on the outside so that the gaps would be uniform. In addition, a lighting fixture has been developed and used for each model with a dedicated fixture having a unique mounting bracket and a reflector so that it can be loaded on the T-bar. For this reason, there is a problem that the double-line construction method requires time and effort because it requires special consideration and a certain number of members. Also, a flange width of 25 mm for mounting the reflector and equipment plate of the lighting equipment.
It is necessary to use four wide T-bars, so two wide lines and slits run on the ceiling,
There is a surface that is unfavorable in terms of design. In addition, it is difficult to match the colors of each other because the T-bar, the reflector of the lighting fixture and the equipment plate are in contact with each other. There is a problem that an inexpensive general-purpose embedded luminaire cannot be used and becomes expensive. The present invention solves these problems and does not require special consideration, can be easily installed with a small number of members, and can also be an inexpensive general-purpose general-purpose embedded luminaire used in the discarding and pasting method. It is an object to provide a so-called double line construction method that is inexpensive and has an excellent appearance.

[0004]

In the system ceiling of the semi-concealed construction method of the present invention, the above-mentioned problem is to illuminate between two T bars arranged in parallel and having a ceiling plate mounted on an outer horizontal flange. The equipment and the equipment plate are provided in parallel with the T bar by providing a slit line and continuously arranged,
Simplified construction system with air-conditioning outlet / suction port arranged in the slit line or two T-bars arranged in parallel are bridged with a U-shaped hanging bracket, and air-conditioning is blown to the U-shaped hanging bracket. -It is solved by the above-mentioned simple construction system ceiling with a suction port and a lighting fixture attached.

The main parts are the T-bars 3, 4 of the book, the equipment line connecting the luminaire 5 and the equipment plate 6, the air conditioning outlet / suction port 18, and the two brackets 7, 7 having a substantially U-shaped cross section. Two substantially U-shaped hanging brackets 7, 7 (hereinafter referred to as hanging brackets)
Both ends of each of the T-bars 3 and 4 are attached to the heads of the T-bars 3 and 4 by bridging, and the two T-bars 3 and 4 are securely fixed in parallel to a predetermined width. The lighting fixture 5 is attached to a predetermined position of the metal fittings 7, 7 and slit lines 10, 11 are provided between the T-bars 3, 4 and the equipment line. Further, the two hanging metal fittings 7, 7 are bridged to each other, and an air-conditioning outlet / intake port 18 is attached at a predetermined position and is arranged in the slit lines 10, 11. The luminaire 5 and the equipment plate 6 may be connected by a joiner 23, for example, as shown in FIG. 4, or the short side of the reflector plate flange of the certification equipment and the end of the equipment plate are fitted as shown in FIG. It may be directly connected.

[0006]

Embodiments of the present invention will be described in detail with reference to the drawings. The equipment line in which the lighting fixture 5 and the equipment plate 6 according to the present invention are connected to each other is formed in a line shape in the T-bars 3 and 4 in which the ceiling plates 1 and 2 are placed in parallel as shown in FIG. ing.
As shown in FIGS. 1 and 2, the two T bars 3 and 4 are fixed to the lighting device 5 with screws 8 and 9 so as to be equally spaced by two hooks 7 and 7. The hanging metal 7 is T bar-3, 4
Has a structure that can be fixed to the heads of T-bars 3 and 4 with screws 8 and 9, and screw holes so that the lighting fixture 5 and the air conditioning outlet / suction port 18 can be attached as shown in FIG. 1
6 or the locking claw 15 is arranged at the mounting position. The lighting fixture 5 has a frame 1 of the lighting fixture 5 mounted on a metal fitting 7 in which a locking claw 15 is arranged so as to come to the central position of the T-bars 3 and 4.
4 and can be fixed with a locking screw 19 or the like if necessary. By making the horizontal length of the hanging metal fitting 7 the width of the lighting fixture + the slit line width + the width of the T bar, the slit lines are equally spaced between the T-bar horizontal flanges 3 and 4 and the flange of the reflector 12 of the lighting fixture 5. 10 and 11 are formed.
The equipment plate 6 is connected to the short flange of the reflection plate 12 of the luminaire 5 as shown in FIG. 4 or FIG. 5, and the equipment plate width is made equal to the luminaire width so that the luminaire 5 and the equipment plate 6 are connected to each other. An equipment line that provides a clean finish by the continuous configuration of is formed. The hanging metal 7 is preferably attached so as to be located between the reflector 12 and the frame 14 of the lighting fixture 5, but may be attached to the upper portion of the frame 14 of the lighting fixture 5. When the air conditioning outlet / suction port 18 is attached to the slit lines 10 and 11, as shown in FIG. 3, the locking screw holes 17 on the locking plate 20 of the air conditioning outlet / suction port 18 and the air conditioning of the metal fitting 7 are provided. The mounting position of the metal fitting 7 can be adjusted in advance so that the positions of the mounting screw holes 16 of the blowout / suction port 18 are aligned, and the mounting members 7 can be mounted by the locking screws 21.

[0007]

As described above, according to the present invention, a facility line formed by connecting a lighting fixture and a facility plate can be formed without using a T-bar, so that there are three colors of the T-bar flange, the lighting fixture reflector and the facility plate. There is no difficulty in harmonizing
By adjusting the colors of the reflector of the lighting fixture and the equipment plate, the flange shape can be made the same, so no labor is required and a wide line such as 25 mm of the T-bar flange appears. In addition, it is possible to form a facility line that is slim and has an excellent design, with a reflector flange width of 10 to 15 mm for lighting equipment. In addition, since the equipment line formed by connecting the lighting fixture and the equipment plate can be formed excluding the T-bar of the conventional method, the width of the T-bar flange can be narrowed, so that the ceiling plate can be placed on the outer horizontal flange. Since the width of the equipment line sandwiched between two existing T-bars can be narrowed, the equipment line is slim and the appearance is excellent. Further, since the number of T-bars is reduced to two, the number of ceiling constituent members is reduced to the level commonly known as the single line construction method.
