The distance between the small insertion claw 35 and the vertical piece 33 is greater than the wall thickness of the longitudinal side wall 12 .

As shown in FIG. 3(b), a connecting projecting piece 36 continues to the upper end of the vertical piece 33. As shown in FIG. The connecting projecting piece 36 is perpendicular to the vertical piece 33 and horizontally projects to the side opposite to the horizontal piece 32 . A notch hole 36 a is formed in the connecting projecting piece 36 . The cutout hole 36a extends to the opposite side of the vertical piece 33 in the connecting projecting piece 36 and reaches the edge 36e on the opposite side. A guide opening 36c of the notch hole 36a is formed in the edge 36e of the connecting projecting piece 36. As shown in FIG. The width of the guide opening 36c and the diameter of the notch hole 36a are larger than the diameter of the hanging member 3 (thread diameter). Therefore, the hanging member 2 can be received in the notch hole 36a from the side of the connecting projecting piece 36 through the guide opening 36c. A pair of locking claws 37 are formed on both sides of the edge 36e of the connecting projecting piece 36 across the guide opening 36c.

The mixing chamber 10 is installed on the ceiling of the building as follows.
Nuts 51 to 54 are screwed in advance to the suspending member 2 consisting of a full screw.
The lower connecting fitting 30 is brought close to the hanging member 2 from the side of the hanging member 2, and the lower end of the hanging member 2 is inserted into the notch hole 36a through the guide opening 36c. Then, the connecting projecting piece 36 is placed on the receiving nut 54 . By hooking the locking claw 37 on the receiving nut 54, the connecting fitting 30 can be prevented from coming off from the suspension member 2. - 特許庁
Next, the lower corner 17 of the mixing chamber 10 is applied to the angle portion 31 and the insertion claws 34 and 35 are inserted into the walls 12 and 13 . As a result, the mixing chamber 10 can be suspended and supported by the suspending member 2 via the connecting fittings 30 . The load of the mixing chamber 10 can be received by the connecting fitting 30 . Since the insertion claws 34 and 35 are embedded in the walls 12 and 13 and do not protrude into the air flow path of the mixing chamber 10, the heat in the air flow path can be prevented from escaping through the connecting fitting 30. Insulation can be secured.

After that, the connecting projecting piece 36 is strongly sandwiched between the pressing nut 53 and the receiving nut 54 . Thereby, the mixing chamber 10 is fixed to the hanging member 2 via the connecting fitting 30 .

Subsequently, the upper connecting fitting 20 is brought closer to the suspension member 2 from the side of the suspension member 2, and the intermediate portion of the suspension member 2 is inserted into the notch hole 26a through the guide opening 26c. Then, the connecting projecting piece 26 is placed on the receiving nut 52 . By hooking the locking claw 27 on the receiving nut 52, the connecting fitting 20 can be prevented from coming off from the suspension member 2.例文帳に追加
Around this time, the angle portion 21 is applied to the upper corner 16 of the mixing chamber 10 and the insertion claws 24 and 25 are inserted into the wall members 12 and 11 . Since the insertion claws 24 and 25 are embedded in the walls 12 and 11 and do not protrude into the air flow path of the mixing chamber 10, the heat in the air flow path can be prevented from escaping through the connecting fitting 20. Insulation can be secured.
Further, the connecting fitting 20 is fixed to the suspension member 2 by sandwiching the connecting projecting piece 26 with the nuts 51 and 52 . As a result, the mixing chamber 10 can be pushed from above by the connecting fitting 20 . Even if vibration due to an earthquake or the like is applied, the mixing chamber 10 can be prevented from slipping out of the insertion claws 24, 25, 34, 35 of the connecting fittings 20, 30, and the mixing chamber 10 can be maintained in a supported state.

Note that the construction procedure can be changed as appropriate. After attaching the connecting fittings 20, 30 to the mixing chamber 10 by inserting the insertion claws 24, 25, 34, 35 of the connecting fittings 20, 30 into the corners 16, 17 of the mixing chamber 10 in advance, the connecting fittings 20, 30 are attached. 30 can also be fixed to the hanger 2 . Therefore, the degree of freedom in construction can be increased.

The work of attaching the connecting metal fittings 20 to the suspension member 2 and the work of connecting the mixing chamber 10 and the connecting metal fittings 20 are both simple tasks and can be completed in a short time. Therefore, according to the air-conditioning support structure 1, the construction time can be significantly reduced as compared with the conventional support structure using a hanging frame (see Patent Document 1, etc.).

The present invention is not limited to the embodiments, and various modifications can be made without departing from the scope of the invention.
For example, of the upper and lower connecting metal fittings 20 and 30, the upper connecting metal fitting 20 may be omitted, and the air conditioning support device 3 may be configured only with the lower connecting metal fitting 30. FIG.
Alternatively, of the upper and lower connecting fittings 20, 30, the lower connecting fitting 30 may be omitted, and instead, another supporting means may be used to support the air conditioning member from below.
The air-conditioning member is not limited to the mixing chamber 10, but may be a distribution chamber or an air-conditioning duct.
