Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for attaching a bathroom ventilation dryer to a ceiling plate of a bathroom, and a method of attaching the apparatus.
[0002]
[Prior art]
For example, as shown in FIG. 1, the bathroom ventilation dryer is formed by a main body 1 including a heater, a blower, and the like, and a decorative panel 2 attached to the lower surface of the main body 1. To install this bathroom ventilation dryer on the ceiling plate of the bathroom, the following procedure is used.
[0003]
As shown in FIG. 1, the mounting opening 4 is formed in the ceiling board 3, and the awning 5 is arranged along the opening edge of the mounting opening 4 on the back surface of the ceiling board 3. The main body 1 is inserted into the mounting opening 4 from inside the bathroom, and as shown in FIG. 2, the mounting flange 6 of the main body 1 is brought into contact with the bathroom side surface of the ceiling board 3 and from the hole 7 of the mounting flange 6 The main body 1 is attached to the ceiling board 3 by screwing the wood screw 8 through the ceiling board 3 and screwing it into the wooden board 5. Thereafter, the panel 2 is mounted by screwing a screw 10 from the hole 9 of the panel 2 into the screw hole 11 of the mounting flange 6 of the main body 1.
[0004]
That is, since the ceiling board 3 is thin, the screw-in allowance of the wood screw 10 is small, and the mounting strength of the main body 1 is insufficient. By screwing the wood screw 10, the screwing allowance is increased and the mounting strength of the main body 1 is sufficient.
[0005]
[Problems to be solved by the invention]
When the main body 1 is mounted as described above, the wood screw 10 is lifted from the ceiling plate 3 without being screwed into the wood plate 5, so that the wood plate 5 is previously attached to the back surface of the ceiling plate 3 with an adhesive or the like. It is fixed, or another worker presses the wooden bar 5 and screws the wooden screw 10 into the wooden bar 5.
[0006]
However, when the wood 5 is bonded in advance with an adhesive or the like, a wood-specific adhesive such as a woodworking bond is used, but this adhesive takes a long time to be applied and dried. Since the main body 1 is attached after a long time until the adhesive dries, the working efficiency is poor.
[0007]
In addition, the fixing with the adhesive is low in reliability, and if the wooden bar 5 is not sufficiently fixed, it moves when the wooden screw 10 is screwed in, so that the wooden bar 5 is fixed again with the adhesive. , Work efficiency will be very bad.
[0008]
In addition, in the method where other workers press the wooden bar 5, two workers are required, and it is possible in the case of new construction of a building, but when it is attached to an existing building by renovation etc. Is impossible because there is no space for a hand or body to enter above the ceiling board.
