Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a device for installing a ceiling-embedded air cleaner.

2. Description of the Related Art Conventionally, this type of ceiling-embedded air cleaner, air conditioner, etc. has been installed in a configuration as shown in FIG. That is, a hanging fitting 5 fixed to the side plate 4 of the main body 3 of the air purifier is attached to the tip of a plurality of bolts 2 suspended from the slab 1.
mounted on. The hanging fitting 5 is formed in an L shape,
The fixed piece 6 is fixed to the side plate 4 with screws 7, and the hanging piece 8 has a through hole in the center, through which the bolt 2 passes, and is suspended by an upper nut 9 and a lower nut 10. Adjust the height accordingly. This height adjustment was performed with the decorative panel 13 removed from the opening 12 of the ceiling material 11.

Problems to be Solved by the Invention With such a conventional configuration, there is no problem if the main body 3 is installed before the ceiling material 11 is installed during construction, but if the main body 3 is installed after the ceiling material 11 is installed or after the existing construction Buildings etc.
Since the ceiling material 11 is installed, it is very difficult to adjust the construction from the slightly thick opening 12 of the main body 3, and it is difficult to adjust the ceiling material to the correct position and height. There was an issue that made it difficult.

The present invention is intended to solve these problems, and aims to facilitate installation of the main body.

Means for Solving the Problem In order to solve this problem, the present invention provides a grommet with a membrane attached to the top surface of the main body, a hanging bolt passing through the grommet with a membrane, and a hanging bolt for connecting with the hanging bolt. The hanging fitting is comprised of a fixing piece having a fixing hole and a hanging piece that protrudes in an L shape, and a hanging piece having a hole through which a hanging bolt passes, and the hanging piece is attached to a side plate. A mounting hole is provided on the inverted board to engage with the provided support hole and to be aligned with the fixing hole, so that the hanging fitting can be attached from both the outside and the inside. .

With this configuration, when the ceiling material is not stretched during construction, hang the hanging piece from the outside of the main body to the support hole, align the mounting hole with the fixing hole, and tighten the bolt and nut. The hanging fitting is fixed, and the hanging bolt is engaged with the hole of the hanging piece.

On the other hand, if the ceiling material is already stretched, pass the hanging bolt through the membrane grommet, hang the hanging piece from the inside of the main body to the support hole, and align the mounting hole with the fixing hole. It is fixed with bolts and nuts, and the hanging bolts are suspended with nuts through holes in the hanging pieces and adjusted.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In FIG. 2, hanging bolts 17 are hung from the slab 16 and are installed at the four corners of the top surface 19 of the main body 18 of the ceiling-embedded air cleaner. It is passed through the inside of the main body 18 as a penetrating means. In the case shown in FIG. 2, the ceiling material (not shown) is already stretched.

At the lower part of the hanging bolt 17, there is an L-shaped hanging fitting 21, an upper nut 22, a lower nut 23, and a bolt 38.
and a nut 39 to suspend the main body 18. The main body 18 is provided with an electric dust collector 25 and a blower 26 for indoor circulation, and the indoor air sucked in from the suction port 27 passes through the dust collector 25, and the purified air is sent to the blower 25. The air is blown out from the air outlet 28. In FIG. 1, the hanging fitting 21 will be explained in detail.

That is, the hanging fitting 21 includes a fixing hole 30, a fixing piece 32 consisting of a hanging piece 31 formed by a notch, and a hanging piece 34 having an elongated hole 33 through which the hanging bolt 17 passes.
It is formed into an L shape. On the other hand, in order to hang the hanging piece 31, the side plate 35 of the main body 18 is provided with a support hole 36, and a mounting hole 37 that matches the fixing hole 30 at a position where the support hole 36 is hung and pushed upward. A bolt 38 passing through the fixing hole 30 and the mounting hole 37, and a nut 3
There are 9. Note that the membrane grommet 20 is normally in a sealed state, but when suspending the hanging fitting 21a from the inside of the main body 18, the membrane grommet 20 breaks the central thin membrane part so that the hanging bolt 17 can pass through. I have to.

In the above configuration, depending on the construction progress of the building, the ceiling material may or may not be stretched. If the ceiling material has not yet been installed, the work can be done with sufficient margin from the outside of the side panels 35. That is, from the state in which the hanging bolt 17 is suspended from the slab 16, the hanging fitting 21 is hung from the outside through the support hole 36 of the side plate 35 and the hanging piece 31, and the bolt 38 is inserted into the fixing hole 30 while being pushed up.
and the mounting hole 37 and tightened with a nut 39 to fix the hanging fitting 21. Then, the hanging bolt 17 is inserted into the hole 33, and the height of the main body 18 is adjusted using the upper nut 22 and the lower nut 23.

On the other hand, if the ceiling material is already stretched, the top surface 19
The membrane grommet 20 is broken with the hanging bolt 17, and the main body 1 is
8, and insert the hanging fitting 21a from the inside into the support hole 3.
6 with the hook 31, and in a pushed up state, align the fixing hole 30 and the mounting hole 37, insert the bolt 38, and fix with the nut 39. Then, the hanging bolt 17 is inserted into the hole 33, and the height of the main body 18 is adjusted using the upper nut 22 and the lower nut 23. After the ceiling material is stretched in this way, construction work will be carried out through the openings that make up the inlet 27 and the outlet 28, so the hanging work will be done inside the main unit. , it becomes very simple.

Effects of the Invention As is clear from the description of the above embodiments, the present invention provides a grommet with a membrane on the top surface, a hanging fitting connected to a hanging bolt, a fixing piece and a hanging piece, and a hanging piece. In addition to providing a hole, a support hole corresponding to the hanging piece and the fixing hole, and a mounting hole are provided in the side plate of the main body, so the hanging fitting can be connected to the hanging bolt from either the outside or the inside of the main body. This makes installation easy regardless of the progress of construction work. In other words, it can be easily installed even in existing buildings.

In addition, the hanging piece of the hanging bracket allows for mounting bolts.

Even when the nuts are tightened, a minimum hanging force remains, allowing the main body to be installed safely and reliably.
