[Background of the invention]

Recently, as a simple air conditioning system that eliminates the intake duct installed in the ceiling of a building, the space formed between the ceiling wall and the ceiling board installed below the ceiling wall is used as a supply chamber for introducing conditioned air. A technology has been developed to do so.

In the conventional ceiling supply chamber structure for air conditioning, for example, as shown in FIG.
installed vertically and horizontally (ceiling rails in each direction are 16A, 16A)
Furthermore, a ceiling reinforcing material 20 is attached vertically or horizontally to the ceiling surface to the hanging fixtures 18 suspended from each ceiling beam 16, and a ceiling base plate 22 is attached to this ceiling reinforcing material 20. The structure includes a large number of parts, which are pasted without interruption and then overlaid on the front surfaces of the ceiling board 24 and ceiling base board 22. In particular, the use of the ceiling reinforcing material 20 and the ceiling base plate 22 increases equipment costs and requires a long time for construction.

In addition, from the supply chamber 26 to the building interior 28
The air outlet 30 for supplying air to the ceiling plate 22 and the ceiling plate 24 is constructed by fitting the outlet parts 32 into through holes provided in series with the ceiling base plate 22 and the ceiling plate 24, which further reduces the number of parts. The number of construction projects is increasing and the construction period is becoming longer.

Furthermore, with such an upper surface configuration of the ceiling plate 26 of the supply chamber 26, the air supplied from the air supply duct 36 may not be smoothly blown into the building interior 28 along the ceiling plate 26 through the air outlet 30. ,
There is a possibility that the liquid may locally accumulate in the supply chamber 26. Furthermore, air cooled by the air conditioner is introduced, and due to its retention, etc.
If a temperature and humidity difference occurs between the air conditioner and the inside of the building 28, dew condensation may occur on the ceiling plate 26 and the like, which may cause trouble to the air conditioning ceiling supply chamber 26.

The present invention was made in view of the above circumstances, and it is possible to reduce equipment costs and shorten the construction period, and allows air to flow smoothly within the supply chamber to be formed, thereby creating a space between the supply chamber and the inside of the building. It is an object of the present invention to provide a ceiling supply chamber structure for air conditioning that does not cause problems even when temperature and humidity differences occur.

[Summary of the invention]

In order to achieve the above object, the present invention provides an air conditioning ceiling supply chamber in which a space formed between a ceiling wall of a building and a ceiling board installed below the ceiling wall is used as a sublit chamber for introducing conditioned air. In the structure, a hanging fixture hangs down from a predetermined position on the ceiling wall, a ceiling rail attached to the hanging fixture, and a heat insulating material is placed inside the hanging fixture that is placed side by side with a predetermined gap above the ceiling rail. a ceiling plate material, the ceiling plate material has a peripheral portion formed thinly, a central portion thickly formed, and an upper surface formed on an arc;
It is characterized in that an air outlet is formed by a gap between the ceiling plate materials arranged side by side.

〔Example〕

Preferred embodiments of the air conditioning ceiling supply chamber structure according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 2 is an overall sectional view of the air conditioning ceiling supply chamber structure according to the present invention.

As shown in FIGS. 2 and 3, in the ceiling supply chamber structure for air conditioning, the ceiling wall
A plurality of hanging tools 44 are suspended from the beam 42 at equal intervals, and a ceiling rail 46 is horizontally attached to the hanging tools 44. This ceiling rail 46 is constituted by a rectangular piece-shaped ceiling plate mounting portion 46A and a box-shaped hanging fixture attachment portion 46B connected to the center of one side (upper surface) of the ceiling plate mounting portion 46A. Each corner of the plurality of ceiling board materials 50 forming the ceiling board 48 is placed on the ceiling board mounting portion 46A of the ceiling rail 46, and each of the ceiling board materials 50 is placed in one direction (in the direction of arrow A). ), a certain gap 52 is formed in the same direction by abutting the adjacent edges of the hanger attachment portion 46B. The ceiling board materials 50 are joined to each other without gaps in a direction perpendicular to one direction (in the direction of arrow B), and are each fixed to the ceiling rail 46 with fasteners such as screws (not shown).

The upper surface of the ceiling plate material 50 is formed into an arc shape along the direction A in which the gap 52 is formed, and the center portion is thick and the adjacent peripheral edge portions of each ceiling plate material 50 are thin. . This ceiling board material 50 is made of a metal material, for example, a grain 5 made of a colored iron plate.
4, and the inside thereof is filled with a heat insulating material 56, so that even if the upper surface of the material 50 is cooled by air from the air supply duct, the heat insulating material 56 is filled.
Due to this action, the lower surface is cooled and no condensation occurs on the lower surface.

With this configuration, the upper floor 40, the beam 4
2. A supply chamber 60 is formed in the ceiling by the ceiling plate 48 and side walls 58, and air 64 is supplied to this supply chamber 60 from an air supply duct 62.
is supplied to the building interior 66 using the gaps 52 between the ceiling panel materials 50 as air outlets, and is supplied to the building interior 66 through the exhaust duct 68.
It is discharged from

According to the air conditioning supply chamber structure according to the present embodiment configured as described above, the ceiling plate 48 is composed only of the ceiling plate material 50 placed on the ceiling rail 46, so that the structure shown in FIG. The conventional ceiling reinforcing material 20 and ceiling base plate 22 as shown are omitted, and manufacturing and assembly costs can be significantly reduced due to the reduced number of parts. In addition, since the gaps 52 formed between the ceiling plate materials 50 are used as air outlets, unlike the conventional air outlets 30, no special hole-drilling process is required, and fitting of the outlet parts 32 is also not required. I don't. Therefore, in this sense as well, the number of parts can be reduced, equipment costs can be reduced, and construction can be made easier and shorter. In particular, if the ceiling beam 46 is made into a piece, supporting the corner portions of each ceiling plate material 50, and opening the mutual spacing between the ceiling plate materials 50, the air outlet does not require any members. It will be formed together with the installation of the ceiling panel. In addition, since each ceiling plate material 50 is thick at the center and thin at the adjacent edge forming the air outlet, the supply chamber 6
The air within 0 is smoothly blown out into the building interior 66 from the gap 52 serving as an air outlet without being stagnant along the arcuate upper surface of the ceiling plate material 50. Moreover, based on its arcuate cross-sectional shape, the ceiling plate material 50 can ensure sufficient mechanical strength, so there is no possibility of local contraction or expansion caused by the cold and warm air supplied into the supply chamber 60. There is no such thing. In addition, since the ceiling board material 50 has a structure in which a heat insulating material 56 is filled between shells 54 made of colored iron plates, it is possible to reduce weight, and the color effect is directly exhibited, making it suitable for stores with large ceiling areas. Even when there is a temperature and humidity difference between the supply chamber 60 and the building interior 66, the thick ceiling board material 50 has an effect of reliably preventing dew condensation due to its heat insulating effect.

In addition, in the above-mentioned embodiment, the ceiling beam 46 is made into a piece, and the mutual spacing 52 of the ceiling board material 50 is opened, but the present invention is not limited to such a structure.
For example, as shown in FIG. 4, the ceiling rail 46 may be formed into a long plate shape that closes the mutual interval between the ceiling board materials 50, and one or more holes 70 for blowing out air may be formed. good.

With such a configuration, it is of course possible to achieve substantially the same effect as the above embodiment without the need to form a special air outlet in the ceiling plate itself, but the opening area of the air outlet can be adjusted arbitrarily. Since the distance air volume changes depending on the distance to the air outlet, this can be made uniform by setting the area of the holes 70 according to the distance. is also possible.

Further, in the above embodiment, the ceiling plate material 50 has a structure in which the shell 54 is filled with the heat insulating material 56, but as shown in FIG. 5, the heat insulating material 56 is housed at intervals, It is also possible to further reduce the weight and reduce the number of equipment.

Furthermore, as shown in FIG. 6, the ceiling plate material 50 may be formed hollow using only a heat insulating material to further reduce the weight.

〔Effect of the invention〕

As explained above, according to the air conditioning ceiling supply chamber structure according to the present invention, efficient air conditioning equipment can be realized with a small number of parts, and it has practical effects such as reducing equipment costs and shortening construction time. Air flows smoothly within the ceiling supply chamber, and since the ceiling board material has a heat insulating effect, no condensation occurs even if there is a temperature or humidity difference between the interior and the interior of the building.
