Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting device for ceiling installation equipment.

(Conventional technology and problems) Conventionally, so-called ceiling-mounted water heaters, heaters, bathtubs, and other appliances that are installed on the ceiling have a mounting bracket A that is fixed to the ceiling as shown in Figure 3. The device body B was fixed with bolts and nuts C. Therefore, during construction, it was necessary to lift the appliance B in the installed position, requiring two workers, and it was very dangerous because it had to be fixed while supporting a heavy object underneath.

(Means for Solving the Problems) The present invention aims to eliminate the above-mentioned conventional drawbacks and improve workability and safety, and is characterized by the following configuration. That is, a pair of mounting frames fixed to the ceiling surface with a predetermined interval, and a pair of mounting frames fixed to the mounting frames,
A reinforcing channel with a nut into which an eye bolt can be screwed, and a low
It consists of a lifting bracket to which a pulley combined with a pulley is attached.

(Example) In the figure, 1 is the ceiling of a balcony or the like (that is, the floor of the upper floor), and 2 is a wall. 3 is a pipe for water, gas, hot water, etc., which is drawn through the wall 2. 4 is the main body of the water heater. Reference numeral 5 designates a pair of mounting metal frames that are fixed to the ceiling surface at a predetermined interval, and are formed with irregularly shaped holes 51 and 52 through which bolts to be fixed to the ceiling are inserted, and both ends of each frame are connected by a channel 6 so that they are integrated. It is becoming. Reference numeral 7 denotes a slide plate that is slidably hooked in the longitudinal horizontal direction of the mounting frame 5, and a screw that is inserted from below through a slit 54 formed in the longitudinal direction of the mounting frame 5 through a spacer 71. 72
The screw 72 is connected without being fixed to prevent it from falling off, and the screw 72 is guided by the slit 54 to slide. 8 is a hook fixed to the slide plate. Reference numeral 9 denotes a hanging metal fitting rotatably attached to one side of the instrument main body 4, and the hook 8
It is something that engages with. Although not shown, a stopper screw is attached to the hook 8 to prevent the hanging fitting 9 from falling off after it is engaged. Reference numeral 10 denotes a bolt for fixing an instrument, which is attached to the mounting frame 5, and is used to tighten and fix an instrument fixing plate 12 fixed to the opposite side of the instrument body 4 from the hanging fitting 9 with a nut (not shown). 11 is a reinforcing channel fixed to the mounting frame 5, and a nut constituting a nut portion 112 into which the eye bolt 111 is screwed is welded. Reference numeral 13 denotes a lifting metal fitting fixed to the upper surface of the instrument main body 4, and has a hole 131 formed therein.

In the above configuration, the construction procedure will be explained. First, fix a pair of bolts to the ceiling surface 1, and then
is inserted into the irregularly shaped hole 51 of the mounting frame 5 to which it is attached and temporarily fixed. Now you can use both hands,
A fixing bolt is inserted into the other hole 52 and fixed. In this state, the slide plate 7 is moved to a suitable position for lifting the instrument body 4. Next, the eye bolt 111 is attached to the reinforcing channel 11, and then the rope 15 combined with the pulley 14 is attached to the eye bolt 111 and the hole 131 of the lifting fitting 13.
Attach to. Then, the rope 15 is pulled to lift the instrument body 4, and the hanging fitting 9 is engaged with the hook 8. This prevents the instrument body 4 from falling, so the pulley 14, rope 15 and eye bolt 111
is removed, the slide plate 7 is slid to the fixed position while the instrument body 4 is suspended from the hook 8, and the instrument fixing plate 12 is fixed to the bolt 10 by lifting the lower end of the instrument body 4 while rotating. Then, connect the pipe 3 to the equipment and the process is complete. In addition, when performing maintenance inspection or removing the equipment, the operation can be performed in the reverse order.

(Effects of the invention) As described above, the invention forms a nut part into which an eye bolt can be screwed into the reinforcing channel of the mounting frame, and fixes a lifting fitting to which a pulley combined with a rope is attached to the top surface of the device body. Therefore, one worker can lift heavy equipment without having to support it under the equipment, which greatly improves workability and safety.
