Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a structure for suspending a ceiling plate by dropping it as a paragraph below the ceiling plate.

[Prior Art] Conventionally, when a drop ceiling board is suspended as a paragraph below the ceiling board, the drop ceiling board is attached to a hanging bolt that is attached with the upper end attached to the ceiling board.

[Problems to be Solved by the Invention] In such a conventional example, since the dropped ceiling plate is hung on the ceiling plate, a large force is applied to the ceiling plate when a large load is applied to the dropped ceiling plate by placing an article on it. However, there is a problem in that the ceiling plate cannot be supported and the ceiling plate is damaged.

The present invention has been made in view of the above points, and an object of the present invention is to drop a ceiling plate so as not to apply a load to the ceiling plate and to damage the ceiling plate by applying a load. The purpose of the present invention is to provide a structure for suspending a dropped ceiling plate that can prevent such a situation.

[Means for Solving the Problems] In order to achieve the above object, the hanging ceiling plate suspension structure of the present invention has an anchor bolt hanging from a ceiling slab and is attached to the anchor bolt above the ceiling plate. Screw the male thread of the suspension bolt so that the suspension bolt can move up and down, insert the suspension bolt into the ceiling plate, and attach it to the lower mounting bracket attached to the upper surface of the drop ceiling plate. The lower ends of are connected.

[Operation] With the above-described configuration, the hanging bolt can be suspended by suspending it with the ceiling slab and inserting it into the ceiling plate, and the ceiling plate can be suspended, and the male screw portion of the hanging bolt can be provided with the female screw hole. It is now possible to adjust the height at which the ceiling plate is suspended by screwing it down.

[Embodiment] The drop ceiling plate 1 has a flash panel structure, and face plates 3 are attached to the top and bottom of a core material 2 so as to be hollow inside. In the case of this embodiment, there are two drop ceiling plates 1a and 1b as the drop ceiling plate 1, which are arranged below the ceiling plate 4. Specifically, the dropped ceiling board 1a is arranged at an appropriate height above the kitchen 5, and the dropped ceiling board 1b is arranged at an appropriate height above the dining table. An upper end of an anchor bolt 7 is embedded in the ceiling slab 6 of the building frame, and the anchor bolt 7 is hung downward. The flat plate-shaped upper mounting member 8 is arranged above the ceiling plate 4, and the anchor bolt 7 is inserted into the through hole 9 of the upper mounting member 8 and the upper mounting member 8 is attached to the anchor bolt 7 with the nut 10. I am doing it. The male screw portion 13 at the upper end of the suspension bolt 12 is screwed into the female screw hole 11 of the upper mounting member 8 to suspend the suspension bolt.
12 vertical positions can be adjusted. The hanging bolt 12 is inserted into an insertion hole 15 formed in the ceiling plate 4 so as to be vertically movable. At this time, the casing having the guide tube 16
17 is attached to the ceiling plate 4, and the hanging bolt 12 is guided by the casing 17. The casing 17 may not have the guide cylinder 16 as shown in FIG.
At the lower part of the hanging bolt 12, there is provided a rotary operation slit 18 on which a rotary tool can be applied when the hanging bolt 12 is rotated to adjust the vertical height. An engaging portion 20 is provided at the lower end of the hanging bolt 12 via a small-diameter portion 19. A lower mounting member 21 is attached to the upper surface of the falling ceiling plate 1 with a screw tool 22, and a small diameter portion 19 is rotatably connected to the lower mounting member 21. One end of the drop ceiling plate 1a of the two drop ceiling plates 1 is connected to the furniture 24, and the other end of the drop ceiling plate 1a and one end of the drop ceiling plate 1b are rotatably connected via a connecting tube 23. .

[Effects of the Invention] As described above, the present invention hangs the anchor bolt from the ceiling slab, connects the hanging bolt to the upper mounting bracket attached to the anchor bolt above the ceiling plate, and inserts the hanging bolt into the ceiling plate. Since the lower end of the hanging bolt is connected to the lower mounting bracket attached to the upper surface of the drop ceiling plate under the ceiling plate, the load from the drop ceiling plate can be borne by the ceiling slab via the hanging bolts and anchor bolts. It is possible to suspend the drop ceiling plate without applying force to it, and it is possible to prevent the ceiling plate from being damaged even if a large load is applied by placing an object on the drop ceiling plate,
Moreover, since the hanging bolt is screwed into the female screw hole of the upper mounting member attached to the anchor bolt so that the vertical position can be freely adjusted, the height of the drop ceiling plate can be adjusted.
