Description

[Detailed description of the invention] (Industrial application field) This invention is a mounting structure for a ceiling-mounted heat exchange unit.
More specifically, the present invention relates to a mounting structure for suspending and supporting a ceiling-mounted heat exchange unit from a ceiling.

(Prior Art) A conventional mounting structure for this type of ceiling-mounted heat exchange unit is described in, for example, Japanese Utility Model Publication No. 58-24096,
There is also one as shown in Fig. 7. That is, four bolts B with nuts N are provided protruding from the ceiling T, while the main body casing 1 of the heat exchange unit U is
Mounting plates A each having an L-shaped cross section in the front-rear direction of the casing 1 are fixed to both sides of the casing 1,
A large hole b is formed at the front and rear bending points of each mounting plate A, through which the nut N portion of the bolt B can be inserted, and a large hole b having a smaller diameter than the nut N is formed continuous with each hole b. A small hole c is formed. After inserting the nut N of the bolt B fixed to the ceiling T into the large hole b, the heat exchange unit U is moved backward, and the small hole c is moved to the nut N position of the bolt B. by causing the mounting plate A to hang on the nut N,
Thereafter, the nut N is screwed until the mounting plate A comes into contact with the ceiling T, so that the heat exchange unit U is suspended and supported on the ceiling T via the mounting plate A.

(Problem to be solved by the invention) However, in the conventional mounting structure, when installing the heat exchange unit U on the ceiling T, the unit U is first lifted by input, and in this state, the nut N of the bolt B is tightened. It is inserted into the large hole b whose inner diameter is not very large, and then, while the unit U is held up, it is moved backward until the small hole c is moved to the nut N position of the bolt B,
Furthermore, after this, it is necessary to screw the nuts N until they are firmly attached to the ceiling, and when installing the heat exchange unit U, the nuts N must be tightened against the bolts B while lifting the heavy heat exchange unit U. Since alignment with the large hole b and bolt tightening must be performed, the installation work is not only hard work but also very dangerous.
