Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a field edge holding metal fitting, and particularly to a field edge holding metal fitting for attaching an intermediate portion of a field edge fixed to the back surface of a ceiling board to a ceiling slab.

[Conventional technology] Conventionally, in order to install a ceiling board, bolts were screwed into inserts buried in the ceiling slab, a hanger was used to fix the frame bracket, and the frame bracket was attached to the ceiling plate.
After installing a plurality of orthogonal roof edges so as to keep them parallel to each other, the vertical position of each roof edge is adjusted to match the height, and the ceiling board is fixed to this roof edge with screws or the like.

However, according to such a conventional method, when narrowing the ceiling space, the length of the bolt and the height of the hanger and the fence holder become obstacles, and there is a limit.

In addition, it takes time and effort to adjust the hanger vertically to match the height of the field edge, and it also requires inserts, bolts, nuts, hangers, etc. to install the field edge holder, which reduces the number of parts. This has the drawback of increasing costs.

Therefore, the present applicant and others fixed runners with U-shaped cross sections with opposing openings to the mutually opposing walls of the room, and installed a field edge with a R-shaped cross section or a U-shaped cross section at the opening of each runner. It has been proposed to fit both ends of the frame and fix the ceiling board to the underside of this edge.
issue)}.

FIG. 5 is a simplified configuration diagram showing an embodiment of the ceiling board mounting structure according to the above application.
Then, runners 4, 4 having a U-shaped cross section, with openings 3, 3 facing each other, are fixed with rivets 6 or the like. The runners 4, 4 are obtained by bending a long metal material into a U-shaped cross section. Reference numeral 5 denotes a field edge having a square-shaped cross section, and both ends thereof are connected to the openings 3, 3 of the respective runners 4, 4.
mated to.

After the field edges 5, 5 are attached, a ceiling plate (not shown) is attached to the lower side of each field edge 5, 5 using screws such as tapping screws. When the screws are screwed in when installing the ceiling board, an upward force may be applied to the edges 5, 5, and the edges 5, 5 may be pushed upward, but this movement is caused by the runners 4, 5.
4 is blocked by the upper plate 4a. Each field edge 5,5 is placed on the lower plate 4b of the runners 4,4, and the vertical position is set at a constant position along the lower plate 4b, so there is no need to adjust the vertical position at all. Further, in order to narrow the ceiling space, it is sufficient to simply move the runners 4, 4 as close as possible to the ceiling slab, and the ceiling space can be narrowed approximately within the allowable range of the height of the roof edge 5.

In addition, since there is no need to use inserts, bolts, nuts, hangers, and edge supports that were conventionally buried in ceiling slabs, the labor required for insert burying work is saved, and the number of parts is reduced, reducing assembly costs. Can be reduced.

In addition, if the span of the roof edges 5, 5 is long, there is a risk that the roof edges 5, 5 will warp downward, but this problem can be avoided by attaching studs to the ceiling slab as shown in Figure 6. Field edges 5, 5 are attached to the fixed hanging frame 30.
What is necessary is just to screw 30a in the middle part.

The above-mentioned Utility Application No. 60-21724 (Utility Application No. 61-
According to the invention of No. 137710), the ceiling space can be narrowed, and there is no need to adjust the vertical direction of the roof edge.
Moreover, since there is no need for hangers, edge holders, etc., assembly costs can be reduced. Additionally, the ceiling can be made deeper as needed, eliminating the need for long, expensive bolts.

[Problems to be solved by the invention] However, if the hanging frame 30 is used to fix the field edge 5 to the ceiling slab as described above, the field edge 5 may be moved in the direction of extension of the runners 4, 4. Therefore, if it becomes necessary to finely adjust the field edge 5 in the left-right direction, this becomes impossible.

That is, the joints between the ceiling panels are made to correspond to the lower surface of the roof edge 5, and the joint sides of the ceiling panels are fixed with screws, etc., but the roof edge 5 is fixed to the ceiling slab with the hanging frame 30a, and multiple screws are used. If they are installed side by side, the joint between the ceiling panels may not be located along the center of the edge 5 when the ceiling panels are installed due to the dimensional error. Therefore, the position of the field edge 5 must be finely adjusted from side to side, which requires a great deal of effort and time.

The present invention was developed to solve the above problems.When the joint between ceiling panels is not located in the center of the roof edge, fine adjustment of the studs in the left and right direction can be easily and quickly made. The purpose of the present invention is to provide a holding fitting.
