In the abutted state, by tightening the tightening bolt 18, the hanging bracket K 1 is attached to the roof frame 19.
Then, the upper end of the suspension bolt 7 is screwed into the screw hole 8 of the raising inclined piece 10 inclined at a required angle with respect to the lower plate portion 2, and the other end of the suspension bolt 7 is connected to a lower portion (not shown). Connect to roof frame.

FIG. 4A is a perspective view showing a hanging bracket K2 according to another embodiment of the present invention, and FIG.
FIG. 5 is a longitudinal sectional view along a section passing through two screw holes 6 and 8. In this hanging metal fitting K2, the positional relationship of the substantially U-shaped cut groove 9 formed in the lower plate portion 2 of the metal fitting body 4 in plan view is the height of the hanging metal fitting K.
Except for the difference from the case of No. 1, the configuration is exactly the same as that of the hanging bracket K1, and the same components are denoted by the same reference numerals and description thereof will be omitted.

A substantially U-shaped cut groove 9 in plan view of the hanging bracket K2 is formed so that the U-shaped opening end 9o is formed between the screw hole 8 and one of the side edges 2b of the lower plate 2. It is formed so that it may be located. That is, the U-shaped cut groove 9 is composed of both lateral grooves 9a, 9a and a vertical groove 9b connecting the both lateral grooves 9a, 9a, and both lateral grooves 9a, 9a are parallel to the front edge 2a of the lower plate portion 2. And the vertical groove 9b is formed so as to be positioned in parallel with one side edge 2b of the lower plate portion 2. The U-shaped cut groove 9 of the hanging metal fitting K2 and the U-shaped cut groove 9 of the hanging metal fitting K1 are in a relationship having a phase difference of 90 degrees on the same plane.

FIG. 5 shows an example of use of the above-mentioned hanging metal fitting K2. In the case where the ceiling material is arranged in an inclined plane shape, the hanging metal fitting K2 is used.
(A) is a side view, (B) is X in (A)
-It is an X-ray sectional view. In this use example, first, a substantially U-shaped cut groove 9 in a plan view of the lower plate portion 2 of the bracket body 4 so that the suspension bolt 7 can be connected to the suspension bracket K2 attached to the inclined roof frame 15 in a vertical posture. The enclosed plate portion is raised downward to be inclined at a predetermined angle (an angle corresponding to the tilt angle of the inclined roof frame 20) with respect to the plate surface of the lower plate portion 2, thereby raising the inclined portion piece 10.

As shown in FIG. 5B, the U-shaped bracket main body 4 of the hanging bracket K2 is connected to the inclined roof frame 20.
, And a suspension bolt 7 is screwed into the screw hole 8 of the raising inclined piece 10, and an upper end of the suspension bolt 7 is attached to the lower flange 20 of the inclined roof frame 20.
a Press strongly against the lower surface, and the reaction force
1 is fixed to the upper surface of the lower flange 20a of the inclined roof frame 20, thereby fixing and holding the hanging fitting K2 to the inclined roof frame 20, and the hanging bolt 7 in the vertical posture.
Connect to 1. In this manner, an inclined bar (not shown) is attached to the lower end of the suspension bolt 7 which is suspended and connected to the suspension fitting K1 by a holder, and a ceiling material is disposed on the inclined bar by a hanger in an inclined plane shape.

As can be seen from the above description of the embodiment,
The hanging metal fittings K1 and K2 according to the present invention are a lower plate of a metal fitting body 4 formed in a substantially U-shape in front view by an upper plate 1, a lower plate 2, and a connecting plate 3 connecting the two plates 1 and 2. A screw hole 8 for screwing the suspension bolt 7 is provided in the part 2, and a substantially U-shaped cut groove 9 is formed so as to surround the screw hole 8, and a plate portion surrounded by the cut groove 9 is formed. Of the lower plate portion 2 so as to be inclined downward by a predetermined angle with respect to the surface of the lower plate portion 2 to form the inclined portion piece 10, so that the structure becomes extremely simple, and the production of the hanging metal fittings K1 and K2. In this case, by pressing a single steel plate having a required size, it can be manufactured as a single component member, and therefore, it can be provided at extremely low cost.

When using the hanging metal fittings K1 and 1K2, the plate portion surrounded by the U-shaped cut groove 9 is formed on the lower plate 2 in accordance with the direction of the hanging bolt 7 connected to the hanging metal fittings K1 and K2. It is only necessary to raise the inclined portion 10 by raising it downward so as to incline at a required angle with respect to the plate surface, so that it is possible to easily cope with various use modes of the suspension bolt 7. In this embodiment, only the case where the inclined portion piece 10 is formed by raising the plate portion surrounded by the U-shaped cut groove 9 by raising it downward has been described.
In the hanging fittings K1 and K2 according to the present invention, the U-shaped cut groove 9 is used.
It can be used as it is without causing the plate portion surrounded by.

In the hanging bracket K1, the U-shaped cut groove 9 provided in the lower plate portion 2 so as to surround the screw hole 8 has a U-shaped opening end 9o sandwiching the screw hole 8 in the lower plate. Since it is formed so as to be located on the opposite side to the tip edge 2a of the portion 2, the plate portion surrounded by the U-shaped cut groove 9 of the lower plate portion 2 is orthogonal to the tip edge 2a of the lower plate portion 2. The hanging bolt 7 can be cut and raised in a direction along the surface, whereby the direction of the hanging bolt 7 can be freely changed along a direction crossing a roof frame or the like to which the hanging metal fitting K1 is attached.

In the hanging bracket K2, the U-shaped cut groove 9 has its U-shaped opening end 9o positioned between the screw hole 8 and the side edge 2a of the lower plate portion 2. Therefore, the plate portion surrounded by the U-shaped cut groove 9 of the lower plate portion 2 can be cut and raised in a direction along a plane parallel to the side edge portion 2b of the lower plate portion 2. The direction of the suspension bolts 7 can be freely changed along a direction that vertically crosses a roof frame or the like to which the suspension fitting K2 is attached.

In the above-described embodiment, the U-shaped cut groove 9 of the lower plate portion 2 is formed with the U-shaped opening end 9 o of the screw hole 8.
Is formed so as to be located on the opposite side to the leading edge 2a of the lower plate portion 2 with the U-shaped opening end 9o between the U-shaped opening end 9o and the side edge 2a of the lower plate portion 2 with the screw hole 8 interposed therebetween. Although only two cases are shown, that is, a case where it is formed so as to be located between, the U-shaped opening end 9o is located between the tip edge 2a of the lower plate portion 2 and the screw hole 8. The cut groove 9 may be formed.

In the above-described embodiment, the case where the U-shaped cut groove 9 is composed of the two lateral grooves 9a, 9a and the vertical groove 9b connecting the both lateral grooves 9a, 9a has been described. The substantially U-shaped cut groove 9 is not limited to the typical U-shaped shape formed by the two lateral grooves 9a, 9a and the vertical groove 9b, but may be formed by deforming the U-shape like a C-shape. It also includes the shape.
