The gap 54 formed by the ceiling beam 52A and the floor beam 50A is closed. Thus, the temperature of the conditioned air in the small sealed area 44 does not change under the influence of the outside air.

The ceiling 32 has blow-out holes 62 at positions corresponding to the sealed small areas 44 and 46 into which the adjusted air flows.
Are formed. The conditioned air that has flowed into the sealed small areas 44 and 46 flows from the air outlet 62 to the first floor living rooms 36 and 3.
Blow out to 8. In addition, since the adjusted air does not flow into the closed small area 48, the outlet 32 is not formed in the ceiling 32 of the building unit 20 corresponding to the closed small area 48.

An exhaust pipe 64 is provided between the ceiling 32 and the air conditioning unit 26. The exhaust pipe 64 is formed in a substantially cylindrical shape, and has a lower end opening toward the living room 40 on the first floor. The exhaust pipe 64 is bent at a substantially right angle at substantially the center, and the upper end thereof is connected to the air conditioning unit 26. The inside of the exhaust pipe 64 is an exhaust path through which air (so-called return air) from the first floor portion 12 of the building is sent back to the air conditioning unit 26, and the return air of the first floor portion 12 is supplied to one building unit 20. From the air conditioning unit 26. The exhaust pipe 64 is attached to the building unit 22 on the second floor in advance, and the building unit 2 is installed at the construction site.
The exhaust pipe 64 is arranged between the ceiling 32 and the air-conditioning unit 26 simply by mounting the second unit 2 on the building units 16, 18, 20 on the first floor.

The duct structure 66 according to the present embodiment includes the blower pipe 28, the ceiling 32 forming the closed area 42,
It is constituted by an exhaust pipe 64. Therefore, the air-conditioning unit 26 and the living rooms 36, 3
A circulation path for circulating air is formed between the first and second air passages 8 and 40.

For the living room 34 on the second floor, a supply pipe and a discharge pipe (both not shown) are provided between the air conditioning unit 26 and the ceiling 24 to supply the adjusted air from the air conditioning unit 26. At the same time, return air is returned to the air conditioning unit 26 to perform air conditioning.

Next, the duct structure 66 according to the present embodiment will be described.
And the operation of the duct structure 66 will be described.

In order to form the duct structure 66, first, the building units 16, 18, and 20 on the first floor are installed. Each building unit 16, 18, 20 has a ceiling beam 50 in advance.
A, 50B, 50C, and 50D are attached.

Next, the second-floor building unit 22 is installed above the first-floor building units 16, 18, and 20. The floor unit 52A,
52B, 52C and 52D are attached, and an airtight material 56 is attached to the floor beams 52A and 52C in advance. For this reason, the building unit 22 on the second floor portion
Is installed, the sealed small areas 44, 46, and 48 are formed, and the conditioned air can be moved between the sealed small area 46 and the sealed small area 44 by the gap 54. The air-tight material 56 prevents the adjusted air from moving between the closed small region 48 and the closed small region 48.

Further, as shown in FIG.
Since the airtight material 56 is also attached to 2A in advance, when the floor beam 52A is installed above the ceiling beam 50A, the floor beam 5
The gap 54 between 2A and the ceiling beam 50A is closed.

When the air-conditioning unit 26 is operated after the completion of the house 10, the adjusted air is sent into the closed small area 46 through the discharge path of the blower pipe 28. The conditioned air further flows into the closed small area 44 from the gap 54 and the wiring small hole 58. Then, the adjusted air is supplied from the outlet 62 to each of the living rooms 36 and 38 on the first floor. Further, the air in the first floor portion 12 is returned from the living room 40 to the air conditioning unit 26 through the exhaust path in the exhaust pipe 64 as return air, and as a result, the air is returned to the air conditioning unit 26.
And the rooms 36, 38, 40. In this way, by circulating the air between the air conditioning unit 26 and the living rooms 36, 38, 40, dew condensation in the sealed small areas 44, 46 and the vicinity thereof is prevented.

The gap 54 between the floor beam 52A facing the building outer wall 60 and the ceiling beam 50A in the closed small area 44 is
The closed small area 44 is closed by the airtight material 56.
The temperature of the conditioned air inside does not change under the influence of outside air. In addition, air does not flow into the sealed small area 48 corresponding to the living room 40 in which the adjusted air need not be supplied by the airtight material 56. Thus, the operation efficiency of the air conditioning unit 26 can be improved.

When hot air is sent from the air conditioning unit 26 to the closed small areas 46 and 44 as adjusted air, the temperature of the second floor 30 is raised by the heat of the hot air.
The living room 34 on the second floor can be heated by so-called floor heating.

As described above, in the duct structure according to the present embodiment, only the building unit 22 of the second floor portion 14 is installed at the construction site, and the space between the first floor portion 12 and the second floor portion 14 of the house 10 is provided. In addition, the closed area 42 serving as the flow path of the adjusted air is formed, and there is no need to install a horizontal duct at the construction site as in the related art. For this reason, the construction process of the house 10 is reduced, and the construction period can be shortened. Also, the construction cost is reduced.

Further, an exhaust pipe 64 is also attached to the building unit 22 on the second floor in advance, and the building unit 22 on the second floor is connected to the building units 16 and 1 on the first floor at the construction site.
The exhaust pipe 64 is disposed between the ceiling 32 of the first floor and the air conditioning unit 26 simply by being installed on the upper surface of the air conditioner 8 or 20.
Therefore, the construction period is further shortened as compared with the case where the exhaust pipe 64 is installed at the construction site.

Since there is no horizontal duct between the floor 30 on the second floor and the ceiling 32 on the first floor, the ceiling beams 50A, 50A
B, 50C, 50D and floor beams 52A, 52B, 52C, 5
There is no need to form through holes for passing horizontal ducts in 2D or the like, and ceiling beams 50A, 50B, 50C, 50
The predetermined strength can be maintained even if the height (beam structure) of D and the floor beams 52A, 52B, 52C, 52D is reduced.
Therefore, the ceiling 32 on the first floor does not become low, and it is possible to secure a certain height in the living rooms 36, 38, 40 on the first floor.

In the above description, an example of a duct structure in which the gap 54 between the floor beam 52C and the ceiling beam 50C is closed by the airtight material 56 so that the adjusted air does not flow into the closed small region 48 is taken as an example. However, the position at which the flow of the adjusted air is blocked by the airtight material 56 is not limited to this. That is, any gap formed by a plurality of ceiling beams and floor beams between the ceiling 32 on the first floor and the floor 30 on the second floor is closed by the airtight material 56, and the conditioned air is provided in a specific closed small area. Can be prevented from flowing.
Of course, if a small hole for wiring or the like is formed in the ceiling beam or floor beam, this small hole is also closed by the airtight material 56. As a result, among the plurality of rooms on the first floor portion 12, the adjusted air can be prevented from flowing into the closed small area above any room that does not need to supply the adjusted air. 26 can improve the operation efficiency.

In the above description, three closed small areas 4
Although the description has been made by taking as an example the house 10 configured with 4, 46, and 48, the number of closed small areas is not limited to this, and can be changed according to the number of ceiling beams on the first floor and the number of floor beams on the second floor. .
Furthermore, the sealed area 42 does not need to be divided into a plurality of sealed small areas by the ceiling beam on the first floor and the floor beam on the second floor.
Two large enclosed areas may be configured.

The size and number of the outlet holes 62 are not limited, and can be set to a desired size and number according to the required amount of adjusted air for each room in the first floor portion 12. In particular, in the duct structure 66 according to the present embodiment, as can be seen from FIG. 1, the adjusted air is present over almost the entire area above the living rooms 36 and 38. It is easy to form a number of blowout holes 62 at any position on the ceiling 32 (in contrast,
In the conventional duct structure, the outlet can be formed only at the position corresponding to the lower end of the duct arranged between the ceiling on the first floor and the floor on the second floor, for example, when changing the position of the outlet Must also change the structure of the duct).

The material forming the ceiling 32 is not particularly limited, and it is possible to use a general material that has been conventionally used. For example, a material having air permeability is formed in a plate shape. The ceiling 32 may be configured by the above. As described above, when the ceiling 32 is made of a material having air permeability, the hot air or the cold air sent into the closed area 42 causes
It becomes possible to heat or cool the rooms 36, 38 on the first floor.

The building in which the duct structure 66 according to the present embodiment is adopted is not limited to a two-story house, but may be a three-story or more building. That is, in a building with three or more floors, the ceiling of the desired floor that supplies the adjusted air from the air conditioner forms a closed space between the ceiling and the floor immediately above the floor, and thereby the present embodiment Is configured. This makes it possible to supply adjusted air from the air conditioner to floors other than the top floor.
