DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a ceiling material mounting member 1 which is an embodiment of the present invention. The mounting bracket 1 is made of a metal plate such as a galvanized lightweight steel aggregate, and the metal plate forms a vertically long vertical piece 2 which occupies most of the metal plate.
At the appropriate positions on the upper side and the lower side, the vertical pieces 2 are nail holes such as round holes or long holes in the up-down direction for nailing the vertical frame portion C or the wooden ceiling frame ha as described later. 3, a plurality of holes 3 are provided, and an opening 4 is formed so as to face the vertical edge 2a on one side of the vertical piece 2 and is cut out in the lateral direction. The opening 4 is the upper edge of the opening 4. The lower edge 2b of the vertical piece is bent in the horizontal direction to form the upper horizontal piece 5, and the upper edge 2c of the vertical piece, which is the lower edge of the opening, is bent in the same direction as the horizontal piece 5. A lower horizontal piece 6 is formed, and a screw hole 7 for screwing a bolt is provided in the center of both horizontal pieces 5, 6 on the same axis.
Further, substantially mushroom-shaped hook portions 8 and 10 are provided on the lowermost edge 2d of the vertical piece 2 and the other vertical edge 2e on the other side of the vertical piece 2, and the hook portion 8 is illustrated. It is preferable to provide a pair of those having the same size as described above. Of these, the hook portion 10 on the side of the vertical edge 2e may be omitted.

As shown in FIG. 1, the vertical piece 2 is bent into a substantially Z shape in a plan view, and this bent portion serves as a reinforcing rib 2f. The reinforcing rib 2f allows the vertical piece 2 to withstand a load. It can have sex.

FIG. 2 shows a refractory board B which is a refractory material through an H-shaped steel (h) which is a ceiling frame through the above-mentioned ceiling material mounting bracket 1.
The state where is attached is shown.

The openings 4 of the ceiling material mounting bracket 1 are inserted into both ends of the lower web portion h1 of the H-section steel (h),
The bolt 9 is screwed into the upper horizontal piece 5 on the upper side of the opening 4 and the tip of the bolt 9 is pressed against the web portion h1 so that the pair of ceiling material mounting brackets 1 and 1 are opposed to the bolt 9 and the lower side. It is sandwiched by the horizontal piece 6 at both ends of the web portion h1 of the H-shaped steel (h).

In this state, the hook portions 8 and 8 projecting from the lowermost edges of both vertical pieces 2 are provided with a substantially C-shaped edge D, and the C-shaped opening is slightly attached to the hook portion 8. By pressing strongly, the elastic deformation is utilized to engage with the hook portion 8.
By providing a pair of hook portions 8 and 8 as shown in the drawing, a wide field edge D can be engaged as shown in the figure, and in the case of a narrow field edge D, one hook section 8 is provided. It only has to be engaged with. As described above, the hook portions 8 of the same size are juxtaposed to the vertical piece 2 so that the field edges D having different widths can be attached.

Further, a hook portion 10 having a substantially mushroom shape is provided on the other vertical end 2e of the vertical piece 2 of the ceiling material mounting bracket 1 so as to project therefrom.
In the same manner as the above, the field edge D is engaged, and the well-known substantially L-shaped runner 11 is fixed to the ceiling skeleton E by the rivet 12 with the rivet, and the vertical piece of the runner 11 and the ceiling material mounting bracket 1 is fixed. A field rim receiver C is nailed or screwed over a nail hole 3 penetrating the portion 2, and a plurality of field rims D are attached to the field rim receiver C by crossing the field rim receiver C by a hook member F known to the field rim receiver C. .

By the above work, the field edges D can be attached around the H-section steel (h) without any welding operation, and the gypsum board and the silicate calcium film can be attached to these field edges D as in the conventional case. The fireproof board B such as a board may be fixed with nails or screws.

By the way, a hanging bolt is fixed to an H-shaped steel (h), a general wooden beam, a ceiling frame frame ha (FIG. 4) of a purlin, etc., and the hook is fixed to the hanging bolt as described above. There are many cases in which a member, a field edge receiver, and a field edge are attached, and a ceiling material is attached to this. The ceiling material mounting bracket 1 according to the present invention is also characterized in that it can be used also as this general ceiling material mounting bracket.

FIG. 3 shows an example in which the above-mentioned hanging bolt 13 is attached to the H-section steel (h).
The opening 4 of the ceiling material mounting bracket 1 is inserted into the web portion h1 of the above, the hanging bolt 13 is screwed into the screw hole 7 of the horizontal piece 6 on the lower side, and the tip portion thereof is attached to the back side of the web portion h1 as shown in the figure. The ceiling material mounting bracket 1 by pressing it against
The hanging bolt 13 can be hung on the H-shaped steel (h) at the same time as being clamped by the web portion h1 of the shaped steel (h). Therefore, in this state, the hanging bolt 13 can be hung on the hanging bolt 13 as described above. It becomes possible to attach a ceiling frame to this, and to attach a field edge receiver and a field edge.

Further, as shown in FIG. 4, when the hanging bolt 13 is attached to the wooden ceiling frame ha such as a beam or a purlin of a wooden building, a nail hole penetrating the vertical piece 2 of the ceiling material mounting bracket 1 is provided. 3 is used to drive nails or tacks 14 into the wooden ceiling frame ha to attach the ceiling material mounting bracket 1 to the wooden ceiling frame h.
Since the bolt 13 can be fixed to the wooden ceiling frame ha by screwing the hanging bolt 13 into the screw hole 7 of the lower horizontal piece 6 of the ceiling mounting bracket 1, the bolt 13 can be fixed to the wooden ceiling frame ha. The ceiling material can be attached to this as described above.

As described above, according to the ceiling material mounting bracket 1 of the present invention, not only is it used for mounting the refractory board B on the H-shaped steel (h), but also as a normal ceiling material mounting bracket. It has a great feature that it can also be used.

[0022]

According to the first aspect of the present invention, there is no welding work for the field rim receiver and the field rim for attaching the refractory material such as the refractory board to the ceiling frame such as the H-shaped steel for supporting the ceiling skeleton. Since it can be easily attached to the ceiling frame without performing, it does not require a skilled worker for welding work,
In addition, it is possible to construct safely without causing an unexpected situation such as a fire.

Further, according to the present invention, it can be used not only as a metal fitting for attaching a refractory material to a ceiling skeleton, but also when a normal ceiling material is attached to a concrete or wooden ceiling skeleton. This type of ceiling material mounting bracket also has the advantage of being versatile.

According to the second aspect of the present invention, since the reinforcing ribs are integrally formed on the vertical piece in the vertical direction, the reinforcing piece has sufficient strength against the load applied to the vertical piece and is stable. Can be used.
