[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling panel mounting device having an improved mounting device for fixing a ridge and a ridge support.

[0002]

2. Description of the Related Art A ceiling panel mounting device basically fixes both at a ridge supporting a ceiling panel, a ridge receiver orthogonal to the ridge, and an intersection of the ridge and the ridge receiver. It has a fixture and has a structure in which a field margin is hung from a building. A representative example thereof is disclosed in Japanese Utility Model Laid-Open No. 56-71813.

An example disclosed in the above publication is shown in FIGS. 4 to 6 and a conventional example will be described. Conventional ceiling panel mounting equipment,
The ridge 1 supporting the ceiling panel (not shown) is crossed with the ridge receiver 2 serving as a base material of the C-shaped channel,
There is a structure in which the two 1 and 2 are fixed by the fixture 3 at this intersection. The ridge 1 has opposite engaging portions 4 having a U-shaped cross section on both upper sides thereof. The lower wall 5 of the ridge receiver 2 is the engaging portion 4
Abut on the upper wall 6. FIG. 4 shows a fixture 3 for fixing the ridge 1 and the ridge receiver 2.

[0004] The mounting fixture 3 includes a substrate 7 extending in the longitudinal direction of the field receiver 2, a single first mounting piece 8 hanging down from the front side of one side of the substrate 7, and an opposite side of the substrate. And a second mounting piece 9 hanging down from the rear side of the mounting piece, and a hook portion 10 is provided below each of the mounting pieces 8 and 9. As shown in FIG. 6, the attachment 3 is arranged between the upper walls 6 of the engaging portions 4 of the ridge 1 and obliquely in the longitudinal direction of the ridge receiver 2. The rim receiver 2 is located between the mounting pieces 8 and 9 of the mounting tool 3.

From the state shown in FIG. 6, the attachment 3 is rotated in the direction of the arrow, and the hook portion 10 of the attachment 3 is engaged with the engagement portion 4 of the ridge 1 (see FIG. 5). Due to this engagement, the board 7 of the attachment 3 is opposed and separated along the longitudinal direction of the upper wall 11 of the ridge receiver 2. A bolt 12 is screwed into the substrate 7, and the tip of the bolt 12 is brought into contact with the upper wall 11 of the edge support 2.
The lower wall 5 is pressed against the upper wall 6 of the engaging portion 4 of the ridge 1 to fix the ridge receiver 2 to the ridge 1. The field support 2 is suspended from the ceiling using a fishing tree or support.

[0006]

As described above, in the prior art, the attachment 3 is rotated in the direction of the arrow in FIG. There is a need. When this rotation work is performed at the site of the execution, some workers start bolting work before obtaining a required amount of rotation angle. For this reason, the hook portions 1 of the mounting pieces 8 and 9 of the mounting tool 3
When 0 is inadequately engaged with the engaging portion 4 of the ridge 1 and an unexpected external force acts, the fixture 3 separates from the ridge 1, the ridge receiver 2 moves with respect to the ridge 1, and the ceiling Deform the panel.

[0007] Therefore, the present invention is to solve the problems of the prior art as described above.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention intersects a base plate of a fixture with an upper wall of a field margin receiver, and directly rotates the field without rotating the attachment piece. Means for engaging the rim is used.

Specifically, the present invention provides a groove having a substantially U-shaped cross-section with a groove-shaped engaging portion sandwiching an opening and supporting a ceiling panel; A U-shaped field edge receiver, and a fixture for fixing the intersection of the field edge and the field edge receiver in a fixed relation, wherein the fixture is located above the upper wall of the field edge receiver in the longitudinal direction of the field edge receiver. And a pair of spaced-apart mounting pieces that hang down from one side of the board and are integral with the board, and a pair of spaced-apart mounting pieces that hang down from the other side of the board and are integral with the board. A flat surface of a pair of mounting pieces hanging from each side of the substrate and facing each other extends along the longitudinal direction of the field edge, and the pair of mounting pieces are individually and independently facing each other. It is elastically deformable in the direction of approaching and separating, and engages a hook portion having a U-shaped cross section at the tip of each mounting piece with a groove-like engaging portion on a field edge, Through ceiling joist receiving the mounting pieces of, providing a ceiling panel mounting device is brought into contact with the receiving ceiling joist bolts through the substrate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. The panel support member or the edge 21 for supporting the ceiling panel 20 has opposed engaging portions 22 having a U-shaped cross section at an upper portion thereof. The engaging portion 22 opens downward, and has an opening 24 between its upper walls 23. A base channel material, that is, a ridge receiver 25 is arranged orthogonal to the ridge 21. The edge support 25 has a channel shape in cross section, and its lower wall 26
Is seated on the upper wall 23 of the rim 21.

The mounting fixture 27 includes a substrate 28 and a pair of spaced-apart mounting pieces 29, 2 extending downward from one side of the substrate 28.
9 ′ and a pair of spaced apart mounting pieces 30, 30 ′ extending downward from one side of the substrate 28. Each mounting piece 29,2
Outward hook-shaped hook 3 at the lower part of 9 ', 30, 30'
Has one. Screw the bolt 32 into the center of the substrate 28,
The tip is brought into contact with the upper wall 33 of the ridge 25, and the ridge 25 is fixed to the ridge 21. The field support 25 is fixed to a support 34, and is suspended from the support 34 by bolts on the ceiling with nuts.

When fixing the ridge 21 to the ridge receiver 25,
Between one pair of mounting pieces 29, 29 'and the other pair of mounting pieces 3
The edge receiver 25 is passed between 0 and 30 'so that the edge 21 is orthogonal to the edge receiver 25. Each mounting piece 29, 29 ', 30, 3
As shown by the phantom line in FIG. 2, the hook portions 31 of the mounting pieces are inserted into the openings 24 in the upper portions of the ridges 21, and then the elastically deformed mounting pieces are inserted. 2
9, 29 ', 30, 30' are returned to their original shapes, and the hook portions 31
Is engaged with the engaging portion 22.

This work is performed by the operator using the mounting pieces 29, 2
9 ', 30, 30', the opposing mounting pieces 29, 30 in the direction approaching each other, and the opposing mounting pieces 29 ', 3
The hooks 31 may be engaged with the engaging portions 22 by elastically deforming the 0's toward each other. Insufficient engagement between the hook portion 31 and the engaging portion 22 can be immediately discriminated by the operator because the substrate 28 and the upper wall 33 of the ridge receiver 25 are not parallel, and correct engagement can be made. . This engagement does not disengage even when an unexpected external force acts.

The example shown in FIG. 3 is a modification in which a ceiling panel 20 such as a square is attached to a ridge 21. The edge of the ceiling panel 20 is brought into contact with the lower end surface of the ridge 21, and this side edge is fixed to the ridge 21 by screwing an elastic mounting material 35 to the ridge 21. Screws or the like make the decorative panel 36 invisible by snapping it to the mounting member 35.

[0016]

According to the present invention, by properly selecting the dimension between the opposed mounting pieces and the opening dimension of the field edge, the mounting piece can be strongly engaged with the field edge, and the fixed relationship between the two can be strengthened. Also, the mounting operation is extremely simple, since the opposing mounting pieces are only elastically deformed in a direction approaching each other and the hook portion is engaged with the engaging portion.
