Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for fixing a plate material such as a ceiling material or a wall material to a base, and a method for applying the plate material.

[0002]

2. Description of the Related Art Heretofore, a plate metal fitting described in Japanese Patent Laid-Open No. 10-227095 has been known. This construction metal fitting is composed of a hanging metal fitting, a runner material, and two clips. A notch extending in the longitudinal direction is formed on the bottom surface of the hanging fitting, and the hanging fitting can be fixed to the base from below by inserting a screw or other fastening means. In addition, the runner material can be fitted into the notch of the hanging metal fitting. Furthermore, each clip has a substantially U shape, and an upper plate that abuts the bottom surface of the runner material,
It has a lower plate which faces the upper plate and supports a ceiling material as a plate member, and a connecting plate which connects the upper plate and the lower plate. The bottom surface of the runner material, the upper plate and the lower plate are provided with screw holes.
Between the connecting plates of the two clips, a decorative molding material as a parting material capable of concealing the edges of the lower plate and the plate material can be fitted.

When the ceiling material is constructed with this construction metal fitting, first the hanging metal fitting is attached to the base by the fastening means,
Fit the runner material into the notch of the hanging bracket. Then, prepare a clip in which the ceiling material is inserted between the lower plate and the upper plate, and while bringing the upper plate in this state into contact with the runner material, screw the lower plate, the ceiling material and the upper plate through. Secure to the material. After that, a decorative molding material is fitted to both clips. Thus, the construction of the ceiling material is completed.

In the ceiling material thus constructed, the edges of the ceiling materials and the like are hidden by the decorative molding material, so that it has an excellent aesthetic appearance. In addition, when it becomes necessary to remove the ceiling material for renovation after construction, etc., remove the decorative molding material and the screws fixing both clips and the runner material to remove the ceiling material. It is possible to remove it. Therefore, according to this construction metal fitting and its construction method, it is possible to obtain an excellent aesthetic appearance and an excellent construction workability.

[0005]

However, since the above-mentioned conventional metal fittings for plate materials cannot absorb the dimensional error of the plate materials,
It may not be possible to firmly install the plate material, or there may be gaps in the ceiling or walls, which may result in poor aesthetics.

That is, when the size of the plate material is larger than the designed size, even if the edge portion of the plate material is inserted between the lower plate and the upper plate of the clip and the clip and the plate material are fixed to the runner material by screws, The positions of the screw holes in the plate and the upper plate may not match the positions of the screw holes in the runner material, and the plate material may not be fixed to the runner material.

On the other hand, when the size of the plate material is smaller than the designed size, this error can be absorbed only by the width of the lower plate. Even if the error is within the width of the lower plate, the screws that fix the runner material are inserted only in the lower plate and the upper plate, and if they are not inserted in the plate material, the plate material is fixed to the runner material. No, it is just a state of riding on the lower plate of the clip. Further, by inserting a screw near the edge of the plate material, the edge of the plate material may be chipped and the plate material may simply rest on the lower plate of the clip. For this reason,
In these cases, the plate material may be displaced due to a slight force.

Thus, when there is a dimensional error in the plate material,
The plate material cannot be firmly installed, and in an extreme case, the plate material may fall, and a gap may be created in the ceiling or the wall, resulting in an unsatisfactory appearance.

Also, in this metal fitting for plate material, since screws are used to fix both clips to the runner material, the number of parts is large and the manufacturing cost is increased. In addition, when the plate material is installed, it is necessary to fix the screws or remove the screws one by one, and the workability is poor.

The present invention has been made in view of the above-mentioned conventional problems, and can absorb a dimensional error of a plate material, can be manufactured at low cost, and can exhibit excellent construction workability and a construction metal fitting and construction work. Providing a method is an issue to be solved.
