Description

[Detailed Description of the Invention] The present invention relates to a fixture for fixing a ceiling edge holder, and particularly to a fixture in which a ceiling edge holder is held between fixing pieces divided into upper and lower parts.

2. Description of the Related Art Conventionally, a fixing fitting shown in FIG. 1 is known as a fixing fitting for fixing a channel-shaped ceiling edge bracket to a bolt protruding from a ceiling slab. In the figure, reference numeral 1 denotes a channel-shaped field edge support, onto which a field edge fixed to the back surface of the ceiling board is constructed via mounting fittings (not shown). The fixing fitting 3 for fixing the field frame receiver 1 to the bolt 2 is composed of fixing pieces 5 and 6 made by bending a single plate from the center part 4. The bent portions 7a and 7b are bent upward and downward, and the bent portions 7a,
Bending portion 8 bent horizontally from the upper and lower ends of b
a, b, and bent portions 9a, b which are bent from the tips of the bent portions 8a, b so as to face each other.
U-shaped part 1 that holds the upper and lower sides of the field support with b and 9b
0,11 are formed. A hole through which the bolt 3 penetrates is formed in the flat portion 12 of both fixing pieces 5, 6, and a nut 13, which is screwed onto the bolt 2, is inserted through the flat portion 12.
It can be fixed by pinching it with 14.

In this case, in order to fix the field fence 1, the bent part 9
The space between a and 9b must be widened, and the field frame receiver 1 must be inserted between the U-shaped parts 10 and 11 from this opened part. However, the work of widening the fixing pieces 5 and 6 in this way is not easy due to the thick wall of the fixing metal fittings and puts a heavy burden on the operator.Moreover, the distance between the nuts 13 and 14 is large, and the distance between the nuts 13 and 14 is large. When performing work such as spreading the fixing pieces 5 and 6 up and down with the fixing fittings temporarily fixed, the fixing pieces 5 may come into contact with the ceiling slab side, or the nuts 13 and 14 may become an obstacle, making it impossible to maintain sufficient distance. It has the disadvantage that it cannot be expanded. Further, after the fixing pieces 5 and 6 are spread out, unless the upper and lower nuts are tightened, the field edge bracket will fall off, which requires a great deal of effort.

The purpose of the present invention is to eliminate such drawbacks, and will be explained in detail below using examples.

FIG. 2 is a perspective view showing one embodiment of the fixing fitting for the ceiling edge holder according to the present invention, and in the same figure, 1
5 and 16 are fixing pieces fixed to the bolt 17 by nuts (not shown) so as to face each other. A bent part 20 obtained by bending the bent part 20 downward, and a bent part 21 obtained by bending the lower end of this bent part 20 in the horizontal direction.
and a bent part 22 obtained by bending the end of this bent part 21 upward, and these bent parts 20,
21 and 22 form a U-shaped portion 23. The fixing piece 15 has a notch 24 into which the bolt 17 penetrates, and a flat portion 2 that substantially abuts the flat portion 19.
5, a bent portion 26 obtained by bending the end side of this flat portion 25 upward, a bent portion 27 obtained by bending the upper end of this bent portion 26 in the horizontal direction, and It consists of a bent part 28 obtained by bending the end of the bent part 27 downward, and these bent parts 26, 27, 2
8 forms a U-shaped portion 29 that faces downward. Note that the notch 24 is provided on one side a of both sides a and b of the flat portion 25, and this notch 24 extends parallel to the extending direction of the field edge holder 30. Moreover, a knob piece 31 extending downward is provided on the rear end side of the flat part 25.

According to the above configuration, the flat part 19 of the fixed piece 16 is loosely sandwiched between two nuts screwed onto the bolt 17 in advance, and the fixed piece 1
Attach the field edge support 30 so as to hold the lower end of the field edge support 30 on the U-shaped portion 23 of No. 6, and then attach the fixed piece 1
Hold the knob piece 31 of No. 5, place its U-shaped part 29 on the upper part of the field edge support 30, and insert the fixing piece 15 so that the bolt 17 penetrates into the notch 24 of the flat part 25.
Slide the bolt 17 in the direction of extension of the field support 30.
After adjusting the lower surface of the field edge receiver 30 held by the plurality of fixing pieces 15 and 16 set in this way to a predetermined horizontal level, the field edge receiver 30 is tightened in this state by tightening a hat (not shown). 30 can be securely fixed.

Therefore, according to the above structure, the fixing pieces 15 and 16
There is no need to widen the bending pieces 22 and 28 side, and the field edge support 30 can be held between the U-shaped parts 23 and 29 by simply sliding the fixed piece 15 from the side. The work of fixing the receiver 30 becomes easy, and even if the space between the field edge receiver 30 and the ceiling slab is narrow, this work can be easily performed. Further, according to the present invention, when manufacturing the fixing metal fitting, there is no need to bend the fixing pieces 5 and 6 from the center part 4 as in the conventional method, so the number of manufacturing steps can be reduced, costs can be reduced, and material consumption can be reduced. Loss can be reduced. Further, according to the present invention, the upper flat portion 25
Since a knob piece 31 is provided at the tip of the lower flat part 19 and extends downward, this knob piece 31 acts as a guide when the upper fixed piece 15 is slid in the direction of the bolt. It plays its role and allows you to slide easily.
Moreover, since the grip piece 31 can be held, the fixing piece 15 can be easily attached even from a lower work area with poor footing.

As shown in FIG. 3, a downwardly bent stopper 32 may be provided on the side a of the fixing piece 15 where the notch 24 is provided, and this stopper 32 may be brought into contact with the side of the fixing piece 16.
