Description

[Detailed Description of the Invention] The present invention relates to a field edge holder fixing metal fitting, and particularly to a field edge holder fixing metal fitting that can be used in an extremely narrow space under the ceiling.

Conventionally, a channel-shaped field edge support 1 has a length m approximately twice the height l of the field edge support 1, as shown in FIG. 1, and has a hanger 3 fixed to a hanging bolt 2.
Supported by However, according to this, the distance n between the field support 1 and the slab surface 4 increases,
It has a drawback that the space under the attic of the ceiling board provided to the field edge support 1 via the field edge (not shown) cannot be narrowed.

The purpose of this invention is to position the field edge holder as high as possible, bring the ceiling plate attached to the bottom of the field edge holder close to the slab surface, and also make it possible to fix a field edge holder with a small height l. This is to prevent the field edge from touching the nut 20 when fixing the field edge to the receiver, and will be described in detail below using examples.

FIGS. 2 and 3 are a side view and a perspective view showing an embodiment of the field edge holder fixing fitting according to the present invention. In the figures, 5 is a hanging bolt buried in the slab surface 4; A tap screw 7 formed on the field edge receiver fixing metal fitting 6 is screwed into the metal fitting 6, and the metal fitting 6 is fixed to the bolt 5. In this case, a nut 20 is also screwed into the bolt 5, and the metal fitting 6 is held more firmly by this nut 20.

The field edge holder fixing fitting 6 includes a horizontal plate 8, side wall plates 9 and 10 bent downward from the side of the horizontal plate 8, and a horizontal direction from the side of the side wall plate 10, and the side wall plate 9 is bent downward from the side of the horizontal plate 8. It has bolt attachment tongue plates 11 extending in opposite directions. This mounting tongue plate 11 is attached to the lower end 31 of the side wall plate 10.
It is formed by bending the upper portion 30 outward, so that the tongue plate 11 is located at a higher position than the lower end 31. At both ends of the side wall plate 10, a clamping piece 13 having a vertical clamping space 12 between it and the lower surface of the horizontal plate 8 is provided. The upper horizontal body 15 of is inserted. Pressing pieces 17 are provided at both ends of the side wall plate 9 to press the vertical body 16 of the field edge support 14 toward the clamping piece 13 side.

The length S of the clamping piece 13 is set to be approximately the same as or slightly longer than that of the upper horizontal body 15, so that the inside of the vertical body 16 is pressed against the end of the clamping piece 13.
Note that in this embodiment, the end portion 40 of the horizontal plate 8
Although the horizontal plate 8 is not opposed to the upper part of the clamping piece 13 and the pressing piece 17, it goes without saying that the width of the horizontal plate 8 may be made wider and the horizontal plate 8 may be made to face the upper part or protrude to the outside thereof. .

In order to fix the field edge holder 14 in such a configuration, first screw the tap screw 7 into the hanging bolt 5 while rotating the field edge holder fixing fitting 6, and then screw the nut 20 into the mounting tongue plate 11. Then, an upward pressing force is applied to fix the mounting tongue plate 11 to the bolt 5. Next, the horizontal body 15 of the field edge support 14 is inserted into the clamping space 12, the pressing piece 17 is bent, and the outside of the vertical body 16 of the field edge support 14 is pressed with its end.

As a result, the horizontal body 15 is clamped in the clamping space 12, and the vertical body 16 is pressed and clamped between the end of the clamping piece 13 and the end of the pressing piece 17. It also becomes impossible to move in the direction of , and is securely fixed. Generally, the field fence 14 is of a type 1 with a low height l as shown in Fig. 5a.
4 ₁ and a type 14 ₂ with _a high height l as shown in FIG. When attached to the fixing bracket 6, the lower end 2 of the nut 20
Since the lower horizontal body 35 of the field edge support 14 is located lower than in ₀₁ , the field edge does not come into contact with the nut 20 when attaching the field edge to the lower horizontal body 35, which is a disadvantage that the field edge cannot be attached. can be resolved. Furthermore, in this embodiment, the notch a is provided in the bent portion of the pressing piece 17, so that the pressing piece 17 can be easily bent.

FIG. 4 is a perspective view showing another embodiment of the field edge bracket fixing fitting according to the present invention, in which the mounting tongue plate 11
extends from the lower end 31 of the side wall plate 10, and there is a rising portion M on the side wall plate 10 side of this tongue piece 11.
is formed, whereby the tongue piece 11 is lifted above the lower end 31 of the side wall plate 10. Therefore, when fixing the tongue piece 11 with the nut 20, this nut 20 is located at the upper part, so that this nut 20 does not get in the way when fixing the field edge.

In the present invention, a simple circular hole may be provided instead of the tap screw 7, and the bolt 5 may be inserted into this circular hole, and the tongue plate 11 may be held between two nuts positioned above and below the tongue plate 11. Further, the respective ends of the holding piece 13 and the pressing piece 17 are not limited to facing each other, and may be slightly offset.
