Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method and apparatus for installing ceiling-mounted equipment such as water heaters and air conditioners on the ceiling.

[Conventional technology]

The first step is to explain how to install conventional ceiling-mounted equipment and its equipment.
This will be explained with reference to FIG.

In the figure, 1 is an anchor bolt. Reference numeral 2 denotes a mounting frame, and the mounting frame 2 is rectangular and has through holes 2a at four corners for passing through anchor bolts.

Both ends of the mounting frame 2 are bent vertically downward, horizontally bent mounting pieces 2c are extended from both ends of the tip, and tapped holes 2b are provided in the mounting pieces 2c. 4 is a washer, and 5 is a nut screwed into the anchor bolt 1.

Reference numeral 6 denotes a device body of a ceiling-mounted device, and L-shaped connection pieces 7 are fixed on both end faces of this device body 6 with screws in correspondence with the mounting pieces 2c of the mounting frame 2, and the connections are made. Piece 7
A threaded through hole 7a is provided corresponding to the threaded hole 2b of the mounting piece 2c. 8 is a screw.

Hereinafter, a method for mounting a conventional ceiling-mounted device using the above-described conventional ceiling-mounted device mounting device will be described.

First, prepare pilot holes 1a for driving four anchor bolts 1 into the ceiling slab W using a power tool, and insert the four through holes 2a in the mounting frame 2.
Position and drill the hole so that it corresponds to the hole. Four wooden anchor bolts 1 are respectively driven into the four pilot holes 1a and planted. Next, attach the mounting frame 2 to the four anchor bolts 1.
is fitted through the anchor bolt 1 into the through hole 2a of the mounting frame 2, and the nut 5 is screwed into the anchor bolt 1 with the washer 4 interposed, so that the mounting frame 2 is horizontally mounted on the ceiling slab W. Then, use a stepladder or the like to lift the device body 6 in a horizontal position, and then lift the mounting piece 2 of the mounting frame 2.
Place the connecting piece 7 of the device main body 6 on top c. Subsequently, while moving the device main body 6, the screw through hole 7a of the connecting piece 7 on the device main body ε side is aligned with the screw hole 2b of the mounting piece 2c on the mounting frame 2 side. When the screw through hole 7a and the screw hole 2b match, screw the screw 8 through the screw through hole 7a and into the screw hole 2b, fix the mounting piece 2c and the connecting piece 7, and attach the device main body 6 to the mounting frame. Attach to 2. As a result, the device body 6
is installed on the ceiling. The above-mentioned mounting method and device are disclosed in Japanese Utility Model Publication No. 19892-1989.

[Problem that the invention seeks to solve]

However, the above-mentioned conventional method for installing ceiling equipment is
Place the connecting piece 7 of the device body 6 on the mounting piece 2C of the mounting frame 2 fixed to the ceiling slab W, and fix the mounting piece 2C and the connecting piece 7 with screws 8 to attach the device body 6 to the mounting frame 2. Therefore, while the device main body 6 is attached to the mounting frame 2 with the screws 8, the connecting piece 7 of the device main body 6 is merely placed on the mounting piece 2c of the mounting frame 2. For this reason, when fixing the connecting piece 7 and the mounting piece 2c with the screws 8, the device body 6 is held horizontally so that the connecting piece 7 does not shift from the mounting piece 2c and the device body 6 does not fall from the mounting frame 2. It is also necessary to tighten the screw 8 while holding it firmly. It is dangerous to perform such work alone at high places, so multiple workers are required. Furthermore, when performing maintenance inspection, repair, or parts replacement of the device body 6, the device body 6
from the mounting frame 2, and then put the device body 6 back into the mounting frame 2.
Even in such a case, multiple workers are required to avoid the dangers mentioned above.

Further, the above-mentioned conventional ceiling-mounted equipment mounting device has a mounting piece 2c provided on the mounting frame 2, and a threaded hole 2b in the mounting piece 2c.
A connection piece 7 is fixed to the connector body 6 on the one hand, a threaded through hole 7a is provided in the connection piece 7, and the mounting piece 2c and the connection piece 7 are fixed with screws 8 to mount the device body 6. Since it is to be attached to the frame 2, after placing the connecting piece 7 on the mounting piece 2c, connect the screw through hole 7a of the connecting piece 7 and the screw hole 2 of the mounting piece 2c.
It is necessary to carry out accurate positioning work in order to match the position b, and the work is troublesome.

0 can be attached or removed.

〔Effect of the invention〕

As is clear from the above, the method for mounting a ceiling-mounted device of the present invention involves supporting one side of the device main body on a hanging support on one side of the mounting frame, and attaching the connecting piece on the other side of the device main body. The main body of the device is temporarily fixed to the mounting frame by sandwiching it between the other side of the frame and the slide fixture attached to the other side, and in the temporarily fixed state, it is permanently fixed with screws, so it is difficult to fix the device with screws. The main body of the device will not fall off or fall from the mounting frame. Therefore, the main body of the device can be safely and easily attached to and detached from the mounting frame by one person.

In addition, in the ceiling-mounted equipment mounting device of the present invention, the hanging support is integrally provided by hanging down an example of the mounting frame, and the hanging support is fixed to one side of the equipment body. The suspended support of the equipment body can be supported on the suspension support, and the slide fixture is slidably attached to the other side of the mounting frame, and the connection piece is fixed to the other side of the equipment body, making it easy to connect the equipment body. The piece can be held between the mounting frame and the slide fixture.
Therefore, the main body of the device can be temporarily fixed to the mounting frame, and the slide mount and connection piece can be attached in the temporarily fixed state.

The mounting frame can be fixed with screws. Further, a screw hole and a screw through hole are provided in the connection piece of the mounting frame and the device body so as to face each other when the device body is horizontal, and the screw hole and the screw through hole are provided with the screw hole and the screw through hole of the slide mount. A stopper is provided to restrict the sliding of the slide mount when the holes match, so by simply sliding the slide mount until the stopper operates while keeping the main body of the device horizontal, the screw holes and screw through holes can be removed. can be easily aligned.
