  The problem to be solved by the present invention is that the fixing means of the intersection of the field edge and the field edge receiver has a structure that is relatively easy to come off.

The ceiling fall prevention clip according to the present invention is
At the intersection of the field edge and the field edge receiver,
A clip that fixes the field edge and field edge holder to prevent the ceiling from falling,
It consists of a thin plate material having fixing means at both ends,
The middle part of the thin plate material is turned to the lower side of the field edge, and the field edge is supported from below by the hanging parts on both ends.
A crease is added to the thin plate material so that both end portions can be superimposed on the surface of the edge receiving.
Also, with the above-mentioned ceiling fall prevention clip,
The overall shape of the ceiling fall prevention clip is a thin plate material with a substantially crank shape,
The hanging parts on both ends of the thin plate material are distributed to the left and right sides of the field edge holder so as to be sandwiched from the left and right,
Both end portions of the thin plate material can be fixed to the upper horizontal surface of the field receiver.
Furthermore, in the above-mentioned ceiling fall prevention clip,
Fold the suspension part on both ends of the thin plate material from the crease and place both ends close together,
It is also possible to fix both ends to the vertical surface of the field receiver.
Furthermore, in the above-mentioned ceiling fall prevention clip,
It is also possible to open screw holes at both ends of the thin plate material.

Since the ceiling fall prevention clip concerning this invention has the above structures, the following effects can be acquired.
<a> Turn the middle part of the thin plate to the lower side of the field edge, support the field edge from below, and fix both ends to the field edge receiver. Without falling off, it is possible to prevent the ceiling from falling.
<B> Since the folds are added to the surface of the thin plate material, the thin plate material can be easily bent and formed into a predetermined form, and the mounting work can be performed.
<C> Since both ends of the thin plate material are overlapped and fixed, the fixing operation is easy. If fixing such as a screw, a single screw is sufficient.
<D> By allocating both ends of the thin plate material to the left and right sides of the field edge receiver and sandwiching it from the left and right, the intersection of the field edge and the field edge receiver can be bound with a binding wire, Detachment can be prevented by more flexibly constraining the intersection.
<E> By using a fixing bracket for fixing the intersection of the conventional field edge and the field edge receiver, ensuring the conventional workability, and using the clip of the present invention only at the intersection of the appropriate place It becomes possible to prevent the ceiling from falling.
<F> At the time of mounting, both ends of the thin plate material are overlapped and fixed so that both ends are once opened and then wound and closed at the intersection, so that a spring-like repulsion occurs at the lower end, which is screwed By stopping or the like, the lower end functions as a spring washer. Therefore, the screw is difficult to come off due to the washer effect, and it is difficult to remove it.

The ceiling fall prevention clip according to the present invention is formed by turning the middle portion of the thin plate material to the lower side of the field edge, supporting the field edge from below, and fixing both ends to the field edge receiver, It is intended to flexibly restrain the intersection with the field guard so that it does not leave.
Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

<1> Thin Plate Material A clip 1 shown in FIG. 1 has a strip-shaped thin plate material 2 that is point-symmetrically formed around a center O of an intermediate portion 3 to have a crank shape.
A little crease 4 is added to the both ends from the center O, and the suspending portions 5 extend from the crease 4 to the tip side.
A crease 6 is also provided near the tip of the suspending portion 5, and the tip side of the thin plate 2 is a square-shaped fixing portion 7, and a screw hole 8 is opened at the center.
The thin plate material 2 may be a steel plate material, a synthetic resin material, a composite material, or a film material such as an aramid fiber or carbon fiber.

<2> Supporting the field edge A method for fixing the intersection of the field edge 9 and the field edge receiver 10 by the thin plate material 2 will be described.
Both the field edge 9 and the field edge receiver 10 are channel steel, and extend in a direction intersecting the field edge receiver 10, and the field edge 9 is arranged along the lower surface of the field edge receiver 10.
The intermediate part 3 of the thin plate material 2 is turned around the lower side of the field edge 9.
The thin plate member 2 is bent at the crease 4 and the left and right suspension parts 5 are distributed to the left and right sides of the field edge receiver 10 so that the field edge receiver 10 is sandwiched by the left and right suspension parts 5 from the left and right.

<3> Fixing The thin plate member 2 is bent at the crease 6, and the fixing portions 7 at both ends are vertically stacked on the upper horizontal surface 10 a that is the flange of the edge receiver 10.
A screw 11 is passed through the screw hole 8 of the overlapped fixed portion 7 and screwed into the upper horizontal surface 10a to be fixed.
Since there is only one screw 11 to be screwed in, fixing work is easy.
When both end portions 7 are overlapped, a restoring force is exerted on the thin plate member 2 to return to the original flat state by bending, so that a spring-like repulsive force is generated at the lower end portion 7. By fixing the screw 11, the lower end portion functions as a spring washer, and the screw 11 is hardly detached.
In addition to the screws, the fixing part 7 can be fixed using an adhesive or welding, or a hook-shaped protrusion is formed so that the fixing part 7 can be hooked to each other. The protruding piece may be hooked and fixed.
The ceiling fall prevention clip 1 according to the present invention is not used for fixing the intersections of all the field edges 9 and the field edge receivers 10, but is employed at some of the intersections, and the other intersections are conventionally employed. It is also possible to fix by employing a known fixing clip.
Even if the conventional clip comes off due to the vibration at the time of earthquake, the clip 1 of the present invention turns to the lower side of the field edge 9 and supports it, so that the field edge 9 is not detached from the field edge receiver 10 and Can prevent falling.
