BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the drawings. FIG. 1-5 is a diagram showing a preferred embodiment of the present invention. Site members that are the same as or equivalent to those of the related art will be denoted by the same reference numerals and redundant description will be omitted.

In the figure, reference numeral 10 denotes a main body, which is formed by punching, cutting, bending, and the like of a single metal plate, and has a shape in which a generally U-shaped cross section has an upper side inclined and an open side opened. The sandwiching portion 20 and the tilting prevention portion 30 are formed separated by the vertical wall portion 11.

The holding portion 20 is a portion where the holding portion 4 having a hole 4 into which the stud 1 of the ceiling hanger 2 is loosely fitted is inserted and mounted, and is shaped like a U-shape with its opening side narrowed. The two surface portions 21 and 22 are formed to face each other. Insertion holes 23 through which the studs 1 are inserted are formed in the respective surface portions 21 and 22 at opposed positions. Insertion hole 23
Is formed by arranging a loose fitting hole 24 for loose fitting, a temporary fixing hole 25 for temporary fixing, and a locking hole 26 for positive fixing on the stud 1 in a line along the vertical wall portion 11. There is. Therefore, as shown in FIGS. 1 and 3, the insertion hole 23 is a loose fitting hole 24 that is sufficiently larger than the mountain diameter of the stud bolt 1.
However, the loose fitting hole 24 is formed on the open side of the temporary fixing hole 25 and the locking hole 26, which are smaller than the peak diameter and larger than the root diameter. The plate thickness of the main body 10 does not have to be the same as a whole, and at least the peripheral edge of the insertion hole 23 may be equal to or less than the screw pitch of the stud bolt 1.

One surface portion 22 is formed so that its free end portion is warped so as to be separated from the other surface portion 21, and the tip of a claw 27 that is cut and raised on both sides of the free end portion is the other surface portion 21. Is formed in contact with. Nail 27
Is brought into contact with the end surface of the clamped portion 3 of the ceiling hanger 2 mounted between the two surface portions 21 and 22 of the clamp portion 20, and the hole 4 of the clamped portion 3 coincides with the loose fitting hole 24 of the insertion hole 23. It is formed to prevent that. In addition, the claw 27 is the surface portion 2 here.
Although the example formed on No. 2 is shown, it goes without saying that it may be formed on the surface portion 21.

In the tilting prevention portion 30, a surface that is inclined with respect to the surface portion 21 of the sandwiching portion 20 and is separated via the vertical wall portion 11 and the stud 1 inserted through the surface is abutted. Tilt prevention holes 31 are formed which are engaged with each other to keep the posture of the ceiling suspender 2. It is desirable that the tilt-preventing hole 31 has a shape (see FIG. 3) in which the loose fitting hole 24 and the locking hole 26 are connected by an outline when projected vertically on the surface portion 21, but is slightly larger than this. However, the shape is not limited as long as it can appropriately prevent tilting, such as an ellipse.

Next, referring to FIGS. 4 and 5, a method of using the fastener for a ceiling hanger of the present invention will be described.

There are various methods for mounting the metal fittings on the studs 1 which are hung and suspended in the building frame at predetermined intervals, but one example thereof will be described. First, insert the sandwiched portion 3 of the ceiling hanger 2 from the open side of the sandwiching portion 20 of the main body 10 to a position where the loose fitting hole 24 and the hole 4 are aligned (see FIG. 1), and sandwich them with the claws 27 to hold them. Then, this is inserted from the lower end of the stud 1 through the tilting prevention hole 31, the loose fitting hole 24 and the hole 4 to the position indexed from the position where the ceiling material 9 is stretched, and temporarily fixed.

In this temporary fixing, by moving the main body 10 horizontally to the position of the temporary fixing hole 25, the peripheral edge of the temporary fixing hole 25 engages with the root of the screw of the stud bolt 1 and stays.

Since the temporary fixing hole 25 has only a slight arc at the facing position, the temporary fixing hole 25 is not a reliable locking, but is a temporary locking and can be immediately released by the intention. The main body 10 is rotated at that position so that the U-shaped portions 5 of the ceiling suspenders 2 are aligned so that the channel material 7 is attached to the U-shaped portions 5 of the ceiling suspension fitting 2.
From the state of the dotted line, push it open as shown by the solid line to fix it. In this way, a large number of channel materials 7 are arranged in parallel, and the base material 8 is laid so as to be orthogonal to them so as to form a grid-like framework. The base material 8 may be a thin steel plate of the same type as the channel material 7, but may be wood or synthetic resin.

In this state, it is confirmed whether or not the base material 8 is corrugated, and the main body 10 at a position requiring adjustment is released from the position of the temporary fixing hole 25 by moving the body 10 horizontally by releasing the claw 27. At the position of, the main body 10 is made to move freely in the vertical direction by aligning with the stud 1 and further moved to the position of the temporary fixing hole 25, and it is confirmed that there is no waviness, and the main body 10 is inserted into the locking hole 26 position. The main body 10 is pushed in and fixed so that the bolt 1 is locked.

By stretching the ceiling material 9 here, a flat ceiling without waviness can be obtained. If adjustment is necessary in some cases, the ceiling material 9 in the vicinity may be removed and the adjustment may be performed to flatten the surface. In this state, even if the ceiling suspender 2 tries to move out of the holding portion 20, it is blocked by the claw 27, so that the stud bolt 1 does not coincide with the loose fitting hole 24 and the ceiling does not fall.

Further, the peripheral edge of the tilting prevention hole 31 of the tilting prevention part 30 abuts and engages with the screw of the stud bolt 1 to assist the hooking force and maintain the posture of the ceiling suspension 2.

[0021]

According to the first aspect of the present invention, the ceiling suspension is straight, the height can be easily adjusted, and the adjustment position can be easily and quickly fixed in one operation without tightening or loosening the screw. It is possible to provide a fastener for a ceiling hanger that can be released and can be easily attached to the ceiling hanger. Therefore, in the ceiling hanging work for adjusting and attaching a lot of fasteners for the ceiling hanging device, it is possible to reduce the immeasurable number of man-hours and extremely reduce the fatigue of the worker.

According to the second aspect of the invention, in addition to the effect of the first aspect, the ceiling of the ceiling suspender or the ceiling is not disengaged from the stud by securely engaging the valley of the screw with a small force.

According to the third aspect of the present invention, in addition to the effect of the first aspect, the studs are prevented from aligning with the loose fitting holes, so that the metal fittings for the ceiling hanger do not come off.
Therefore, the ceiling hanger and the ceiling do not fall out and come off from the stud.

According to the invention of claim 4, in addition to the effect of claim 1, the insertion of the stud can be facilitated and the tilt angle of the ceiling hanger can be minimized.
