BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling plate holding device for preventing a central portion (a joint portion) of a ceiling plate from being bent downward when the ceiling plate is stretched below a field edge.

[0002]

Conventionally, as the ceiling plate holding device, the ceiling plate
Attaching one end of the thus wooden field edge nail, had fitted the ends of the adjacent side ceiling plate to the end portion of the ceiling plate, this nailing is facing upward nailing required However, the construction was difficult and it was impossible to hold it firmly.

[0003] There are also some such as Japanese Utility Model Publication No. 53-33378 which holds a ceiling plate to a wooden field edge by using fasteners. However, since these are wooden edges, these fasteners are used. Since it is necessary to span the field edge and to make the mounting surface large, there is the drawback that the size of the fastener must be large.

Therefore, as shown in FIGS.
As shown in Japanese Patent Publication No. 14), the field edge 11 is made of metal, and both sides of the lower portion of the ceiling hanging metal fitting 12 are bent to opposite sides to form supporting portions 13 and 13, and a cut-and-raised portion 14 is provided at the center of the lower portion. It is proposed that the bent portion 15 is formed.

[0005]

However, in the above-mentioned structure, when the supporting portions 13 and 13 are made large, it becomes difficult to insert them into the field edge 11, and the cut-and-raised portion 1 that fits with the ceiling plate 16 is provided.
4 and the bent portion 15 cannot be made large, the holding force is not sufficient, and the biggest drawback is that the ceiling hanging metal fitting 12 easily shifts in the arrow direction, and the fitting portion of the ceiling boards 16 and 17 comes off. there were.

Therefore, the present invention has been made to solve the above problems, and a holder for holding a ceiling plate can be easily inserted from below the field edge, and a U-shape for fitting with the ceiling plate. -Shaped fitting part can be enlarged, the holder can be firmly attached to the field edge, and the holding force of the ceiling board is strong, so that the holder does not move in the field edge and fits with the adjacent ceiling board. An object of the present invention is to provide a ceiling plate holding device in which the joint portion does not come off.

[0007]

To achieve the above object, according to the solution to ## ceiling plate holding apparatus of this invention includes a metal ceiling joist, next
The ceiling plate has engaging ends that are engaged with each other, and a metal holder for holding the ceiling plate on the field edge. The holder has an upper mounting portion and a lower portion. U
The plate fitting part bent in a letter shape is connected and formed by the connecting part, and the above-mentioned field edge opens the lower part, and the flat part of the upper part is formed with a long hole in the width direction. at least the tip portion of the mounting portion of the holder is protruded upward causes placed on a flat portion of the field edge, one of the ceiling plate fitting portion of the retainer
Fits to the engaging end of the plate and interposes the plate fitting part
The other end of the ceiling plate to engage the one ceiling plate.
It is characterized by being engaged with the end .

[0008]

According to this invention, the holder for holding the ceiling plate can be easily inserted from below the field rim, and the plate fitting portion for fitting with the ceiling plate can be enlarged, so that it can be firmly fitted.
Furthermore, since the upper attachment part of the retainer can be placed on the upper surface through the long hole of the field edge, it can be easily and firmly attached, and the retainer does not move in the field edge. The fitting part does not come off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Several embodiments of the ceiling plate holding device of the present invention will be described below with reference to FIGS. FIG. 1 is an exploded perspective view of a main part of the first embodiment, FIG. 2 is a vertical sectional side view showing an assembled state thereof, and FIG. 3 is a perspective view thereof. Metal field 2
1 and engaging ends that engage with each other at adjacent ends
A ceiling plate 22 and a metal holder 23 for holding the ceiling plate 22 on the field edge 21. The holder 23 has a tip end portion 25 of a horizontal mounting portion 25 having a screw hole 24 on the upper portion.
a and the rear end portion 25b are connected and formed by a lower U-shaped plate fitting portion 26 and a connecting portion 27, and the field edge 21 has a convex side surface and an opening 28 at the lower portion, and a flat portion 29 at the upper portion. Forms a long hole 30 and a through hole 31 in the width direction, and the front end portion 25a of the mounting portion 25 of the holder 23 projects upward from the long hole 30 and is placed on the flat surface portion 29 of the field edge 21. Later, bolt 32
Together is screwed fastened to the threaded hole 24 through the holes 31, one of the engagement of the ceiling plate 22 to the plate fitting portion 26 of the holder 23
After fitting with the convex portion 33a forming the joint end , one ceiling plate
A convex portion that forms an engaging end of the adjacent ceiling plate 22 in the concave groove 33d of 22.
33c is fitted. That is, the plate of the holder 23
Both engaging ends are engaged with each other with the fitting portion 26 interposed.

With the above construction, the holder 23 for holding the ceiling plate 22 can be easily inserted from below the field edge 21, and the plate fitting portion 26 fitted with the ceiling plate 22 can be enlarged. Therefore, the holder 23 can be firmly fitted, and the upper attachment portion 25 of the holder 23 can be placed on the upper surface through the long hole 30 of the field edge 21 so that the holder 23 can be easily and firmly attached. Next to the ceiling plate 2 without moving
The fitting part with 2 does not come off. Further, as shown in FIG. 2, the stepped portion of the mounting portion 25 has a tip portion 25a.
Comes into close contact with the upper surface of the flat surface portion 29 of the field edge 21, and the rear end portion 25b
Since it is configured so as to be in close contact with the lower surface of the flat surface portion 29, it is not always necessary to fix the front end portion 25a with the bolt 32 as shown in the drawing, and the rear end portion 25b side may be bolted, and not the bolt. Both may be fixed by spot welding or the like.

The second embodiment shown in FIG. 4 is a holder 23 of the preceding example.
The other portion is formed wider than the width of the tip end portion 25a of the mounting portion 25 in FIG. 2 to strengthen the fitting of the plate fitting portion 26, and further the rib 27a is formed in the connecting portion 27 to form the holder 2
It is a solid version of 3. The other points are the same as those in the first embodiment, and will be omitted.

In the third embodiment shown in FIGS. 5 to 6 , the stepped portion of the mounting portion 25 of the previous example (Embodiments 1 and 2) is eliminated and the mounting portion 25 is removed.
Is formed so as to be projected entirely above the long hole 30 and placed on the flat surface portion 29 of the field edge 21, and the lower opening 2
The width of the holding tool 23 is made slightly smaller than the width of the field edge 21 of No. 8 to prevent horizontal rotation of the holding tool 23 in the field edge 21, and the plate fitting portion 26 is attached to one of the ceiling plates 22, 22. The convex portion 35a forming the joint end portion and the concave portion 35b forming the other engaging end portion are fitted to each other.
Since it is the same as Further, in the third embodiment, as shown in FIG. 7, the plate fitting portion 26 is joined and the convex portion 38c ( engaging end) is joined to the upper side of the convex portion 38a ( engaging end) of the 37.
It may be so that engage the Yakuri shape. Further, the mounting portion 25 may be bent to the opposite side as shown by the broken line in FIG.

[0013]

According to the present invention, the holder for holding the ceiling plate can be easily inserted from below the field edge, and the plate fitting portion for fitting with the ceiling plate can be enlarged, so that the holder can be firmly fitted. In addition, since the upper mounting portion of the holder can be placed on the upper surface through the long hole of the field edge, it can be easily and firmly attached, and the holder does not move in the field edge, so that it can be attached to the adjacent ceiling plate. The fitting part of does not come off.
