DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the ceiling frame member support of the present invention will be described with reference to FIGS.

Generally, in the ceiling of a building, a lightweight iron ceiling frame member is hung from a long hanging bolt 2 hung from a ceiling structure via a hanging metal member 3, and a base plate is attached below the ceiling frame member, and further below it. The surface is finished with lath mortar coating.

In the ceiling frame material support of the present invention, the hanging hardware 3 having the support plates 31 projecting from both sides of the upper back surface and the bolts 5 inserted into the long holes 32 formed in the support plate 31 are provided.
And a nut 7 tightened at its end.

The hanging hardware 3 is formed by projecting support plates 31 on both sides of the upper back surface of the conventional one shown in FIGS. 4 and 5. The spacing between the support plates 31 is slightly larger than the outer diameter of the suspension bolt 2. In addition, the opposing surface of each support plate 31 is formed with unevenness 33 that engages with the thread of the suspension bolt 2 when it is attached to the suspension bolt 2. The elongated hole 32 formed in the support plate 31 is formed obliquely as shown in FIG. 2 so that the bolt 5 to be inserted is closer to the hanging hardware 3 main body side. It is designed so that no gap is created between the hanging hardware 3 main body and the hanging bolt 2 when the bolt 5 approaches the hanging hardware 3 main body side. Instead of providing the elongated hole 32, a round hole may be provided at a position corresponding to the lowermost end of the elongated hole 32. Even in that case, some play must be present between the round hole and the bolt 5.

The bolt 5 is formed by forming an annular concave portion 51 having an unevenness in which a mountain portion and a valley portion run in the axial direction at the center portion of an ordinary bolt. The annular recessed portion 51 covers a range in which the suspension bolt 2 is engaged as shown in FIG. 1, and is also a small-diameter portion 51 ′ in which the recessed portion extends to the vicinity of the end portion as shown in FIG. It may be one. In the case of the small-diameter portion 51 ′, when the thin-diameter portion 51 ′ is moved for attachment to the suspension bolt 2, the bolt 5 is retracted so that the small-diameter portion 51 ′ faces the suspension bolt 2, and then the small-diameter portion 51 ′ is advanced to a normal position for positioning. And then tighten the nut 7,
The hanging hardware 3 can be easily moved.

In order to attach the ceiling frame member support thus constructed to the suspension bolts, first, the bolts 5 are inserted into the elongated holes 32 of the respective support plates 31 of the suspension hardware 3 and the nuts 7 are lightly attached.
Tighten. In this state, the lower end of the hanging bolt 2 is inserted between the hanging hardware 3 main body and the bolt 5 to move the supporting tool to a position near the target position. At this time, if the user pulls the bolt head 52 and the nut 7 by hand, the bolt 5 moves to the upper end of the elongated hole 32 and the interval between the hanging hardware 3 main body and the bolt 5 is widened, which facilitates the movement. . When the hand is removed from the bolt 5 while supporting the hanging hardware 3 from below near the target position, the bolt 5 moves to the lower end of the elongated hole 32 and engages with the hanging bolt 2. Then, after finely adjusting the position, the nut 7 is strongly tightened. Since the plates constituting the hanging hardware 3 are as thin as about 2 mm, the nuts 7 are tightened so that the supporting plates 3
1 is pulled inward, and the unevenness 33 formed on each support plate 31 comes into engagement with the hanging bolt 2. Even when a simple round bar having no thread is used instead of the hanging bolt, since the material of the round bar is softer than that of the hanging hardware 3, the concavo-convex 33 bites into and engages with the round bar by tightening the nut 7.

[0014]

Since the present invention is constructed as described above, it has the following effects.

That is, even when a simple long round bar is adopted in place of the hanging bolt, the nut can be tightened several times after temporary mounting and positioning, so that it can be easily mounted in a short time. Moreover, as shown in FIG. 2, it is possible to obtain the same supporting strength as the conventional one in which the hanging metal object is sandwiched by the two nuts and assembled to the hanging bolt, and there is no displacement.
