Description

[0001]
[Industrial applications]
The present invention relates to a metal fitting for temporarily temporarily fixing a ceiling panel.
[0002]
[Prior art]
Although ceiling panels are mounted on the ceiling of the room, there are various mounting structures. In general, a hanging metal is hung at a predetermined height with a hanging bolt, and a rectangular ceiling panel of a fixed size is attached to the hanging metal. Since the hanging fitting is configured to fit the side end of the ceiling panel, the ceiling panel is mounted in a run-in manner from one side. Therefore, it is inconvenient to remove such an interposed ceiling panel for some reason.
[0003]
Therefore, instead of the conventional run-in type, it is possible to adopt a structure in which the ceiling panel is screwed to the ceiling base rail so that the ceiling panel can be attached and detached from any place. However, when the ceiling panel is screwed to the baseboard, another worker must be below to support the ceiling panel in order for one of the workers to rise above the ceiling and fix the screw.
[0004]
Even if the ceiling panel is supported from below, the large ceiling panel must be pushed up from below while being placed on a platform (stepladder). Screwing work is not easy because the condition is not stable. Of course, you may lose stability and fall off your stepladder, which is dangerous.
[0005]
[Problems to be solved by the present invention]
As described above, the conventional ceiling panel mounting has the above-described problems. The problem to be solved by the present invention is this problem, and when a ceiling panel is attached by a screwing structure, a temporary fixing metal which can temporarily temporarily fix the ceiling panel without supporting it below is provided. .
[0006]
[Means for Solving the Problems]
The temporary fixing device for a ceiling panel according to the present invention is characterized in that a screw is erected on the back side of the ceiling panel, and the screw is inserted into a fitting hole formed in a ceiling base rail or a member attached to the ceiling base rail. It is configured not to fall out. That is, the ceiling base rail or the screw is provided with some locking means, and the locking means is locked in the fitting hole or the screw to exhibit the function of preventing the falling off. The temporarily fixed screws are fixed to the ceiling base rail by tightening nuts. Here, the locking means is not particularly limited. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
[0007]
【Example】
FIG. 1 is a schematic view showing a ceiling structure, in which 1 is a ceiling panel, 2 is a ceiling base bar, and 3 is a hanging bracket. The ceiling base bars 2, 2,... Are suspended by hanging brackets 3, 3,. The ceiling panel 1 has a rectangular plate shape, and both sides thereof are fixed to a panel hanger 6 attached to the ceiling base bar 2 to form a ceiling. Also, reference numeral 4 in the figure denotes a duct.
[0008]
Although Figure 2 shows a section of the ceiling structure, ceiling foundation hanger 3, 3 a rail 2 has been suspended is not consolidate hanger bolts 5,5 ... and adjusting nut 7a, and 7b This makes it possible to adjust the heights of the hanging bracket 3 and the ceiling base bar 2. By the way, when the height is determined, the ceiling panels 1, 1,... Are attached to the ceiling base bars 2, 2,..., And the attachment means is structured to be fixed using screws 8, 8,. Also, the height of the ceiling panels 1, 1,... Can be adjusted even after the ceiling panels 1, 1,.
[0009]
Incidentally, the ceiling panel temporary fixing metal of the present invention is a metal fitting that can be temporarily temporarily fixed so as not to be supported from below when the ceiling panel 1 is attached to the panel hanger 6. That is, it is a fall prevention fitting. FIG. 3 shows a state in which the ceiling panel 1 is temporarily fixed. A screw 8 projects upward from the surface of the ceiling panel 1 and a conical nut 9 is formed at the upper end of the screw.
[0010]
The panel hanger 6 has fastening pieces 10, 10 formed horizontally on both lower ends thereof, and the ceiling panel 1 is attached to the fastening pieces 10. The fastening pieces 10 have L-shaped temporary fastening blades 11, 11 are mounted in pairs. The nut 9 passes through the hole formed in the fastening piece 10 and pushes up the temporary fastening blades 11, 11 closing the hole to protrude upward. You will not be able to exit. That is, the nut 9 is locked and fastened to the temporary fastening blades 11, 11.
[0011]
FIGS. 4A and 4B show a state before the screw 8 and the nut 9 are locked to the fastening piece 10, and the temporary fastening blades 11, 11 are horizontal on the upper surface of the fastening piece 10. I'm down. In this state, the hole 12 through which the nut 9 passes is closed, and the nut 9 lifts the temporary fixing blades 11 and 11 and passes through the hole. The temporary fixing blades 11, 11 only fit into the grooves formed on both sides of the fastening piece 10, and the tip side can be lifted as shown in FIG.
[0012]
FIG. 5A shows a state in which the nut 9 is engaged with the temporary fixing blades 11 and 11 to temporarily fix the ceiling panel 1, and the ceiling panel 1 is suspended by screws 8. If the tip is lifted by the nut 9, the temporary fixing blades 11, 11 are tilted down as shown in FIG. 3 to close the hole 12 and prevent the nut 9 from falling if the nut 9 descends again. Then, if the user goes up the ceiling and tightens the nut 9, the ceiling panel 1 is lifted up as shown in FIG.
[0013]
FIG. 6 shows another embodiment of the present invention. The temporary fastener shown in FIG. FIG. 7 shows the screw 13, wherein a slit groove 14 is formed on a side surface of the screw 13, and a locking member 15 is attached to the slit groove 14 in a swingable state. A spring 16 is set at the bottom of the slit groove 14, and the spring force pushes up the locking member 15. However, the locking tool 15 compresses and deforms the spring 16 by the external force P, and fits in the slit groove 14.
[0014]
Accordingly, when the screw 13 attached to the ceiling panel 1 passes through the hole formed in the fastening piece 10 of the ceiling base bar 2, the locking member 15 retreats into the slit groove 14 and passes through the hole. By the way, the locking tool 15 protrudes. Therefore, once the screw 13 has passed through the hole, the screw 13 cannot come out of the hole, and the end face 17 of the locking member 15 comes into contact with the fastening piece 10. In this case, the hole must have a size close to the outer diameter of the screw 13.
[0015]
FIG. 6 shows the state in which the ceiling panel 1 is suspended with the locking members 15 locked on the fastening pieces 10. In this state, if a nut 18 is screwed into the screw 13 and fastened, the ceiling panel 1 is fixed by contacting the fastening piece 10. These embodiments are merely one embodiment of the present invention, and there are various means for temporarily fixing the ceiling panel to the fixing pieces. As described above, the temporary fixing fitting of the ceiling panel of the present invention can be temporarily locked to the ceiling base rail, and the following effects can be obtained.
[0016]
【The invention's effect】
The temporary fixing bracket of the present invention is capable of temporarily fixing the ceiling panel to the ceiling base rail or a member attached to the ceiling base rail, that is, the ceiling panel is lifted from below and locked to the fastening piece of the panel hanger. And it is designed not to fall on its own. Therefore, once temporarily fixed to the panel hanger, there is no need to support the ceiling panel from below, and the work of mounting the ceiling panel is simple and labor-saving.
