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 applied even in extremely narrow attic spaces.

Conventionally, a field edge support 1 that holds a field edge for holding a ceiling board through a field edge mounting bracket is fixed with a nut 4 to a mounting bolt 3 whose upper end protrudes from a ceiling slab surface 2, as shown in FIG. It is supported by a hanger 6 having a U-shaped holding portion 5 at its lower end. However, according to this, since the length of the hanger 6 is about twice as long as the height of the field edge support 1, the distance between the field edge support 1 and the ceiling slab surface 2 becomes long, and this field edge support 1 This method has the disadvantage that it is not possible to narrow the attic space of the ceiling board that is held through the roof edge.

The present invention enables base assembly even when the distance between the ceiling board and the slab surface is extremely narrow, for example, only about 50 mm, and will be explained in detail below using examples.

FIG. 2 is a perspective view showing an embodiment of the field edge holder fixing fitting according to the present invention. In the same figure, 7 and 8 are horizontal plates, and both horizontal plates 7 and 8 have protruding parts from the ceiling slab surface (not shown). A long mounting hole 40 is formed into which the mounting bolt 9 penetrates. The lower horizontal plate 8 is longer than the upper horizontal plate 7, and the length of the extended portion 10 is set to be approximately equal to the length of the upper horizontal portion 12 of the field fence 11. The end portion of the upper horizontal plate 7 rises upwardly, and a clamping piece 14 facing the extension portion 10 is bent from this rising portion 13. A vertical piece 16 is provided at the end ₁₄₁ of the clamping piece 14. A bent piece 22 bent upward is provided on the side edge of the lower horizontal plate 8 and the side edge of its extension 10, and between the upper end of this bent piece 22 and the lower surface of the clamping piece 14, The upper horizontal portion 12 of the field edge support 11 is clamped.

Moreover, since the bent piece 22 is in contact with the side edge of the upper horizontal plate 7, it is in contact with the elongated hole 4 of the upper horizontal plate 7.
It serves as a guide in the direction of extension of 0,
The horizontal plate 7 can be smoothly moved back and forth.

In such a configuration, in order to fix the field edge holder 11, first insert the bolt 9 into the long mounting hole 40 of the field edge holder fixing fitting, and tighten both horizontally with the upper and lower nuts 21 (the lower nut is not shown). Loosely temporarily fasten plates 7 and 8. In this case, the gap m between the tip of the bent piece 22 and the vertical piece 16 is set wide, and the upper horizontal portion 12 of the field edge receiver 11 is connected to the upper end of the bent piece 22 and the clamping piece 14 via this gap. Then, the horizontal plate 7 or ₈ is moved so as to sandwich the vertical portion 111 of the field edge receiver 11 at the distance m between the tip of the bent piece 22 and the vertical piece 16. Next, by tightening the nut 21, the field edge receiver 11 can be fixed. That is, according to this embodiment, it is only necessary to move the horizontal plates 7 and 8 and tighten the nuts 21, or to tighten the bolts provided separately on the vertical piece 16, or to bend the tongue pieces provided on the vertical piece 16. Since there is no need to press the vertical portion ₁₁₁ of the field edge support toward the tip of the bent piece 22, the installation work becomes simple.

In addition, since the bent piece 22 is provided, the horizontal plate 7 slides smoothly in the front and back direction when installing the field edge receiver 11, making installation easy. Even if the horizontal plate 7 is widened widely, the horizontal plate 7 does not rotate and the positional relationship with the horizontal plate 8 is shifted, and the horizontal plate 7 can always be held facing the horizontal plate 8.

FIG. 3 is a simplified configuration diagram showing another embodiment of the field edge holder fixing fitting according to the present invention, and the same parts as in FIG. 2 are designated by the same reference numerals. In FIG. 3, a falling portion ₇₁ is provided at the rear end of the horizontal plate 7, and this is in contact with the rear end of the horizontal plate 8 and acts as a stopper. To prevent the gap m from widening due to movement of the plates 7 and 8. Such a stopper can also be formed by providing a cut-and-raised or bent portion on the outer edge of the horizontal plate 7.

In addition, in the present invention, the fourth piece is used instead of the vertical piece 16.
As shown in the figure, the tongue piece 4 provided at the end of the clamping piece 14
1 may be used.
