Description

[Detailed Description of the Invention] The present invention relates to a metal fitting for orthogonally connecting a ceiling support and an air conditioning base material in a ceiling base.

When installing various equipment such as lighting equipment, ceiling inspection openings, air conditioning equipment, etc. on the ceiling surface in a ceiling base that is mainly formed of conventional field edge receivers and field edges, the field edge and field edge should be installed within the area surrounding the equipment installation area. It is necessary to cut the edge support and reinforce this cut part by building another field edge and field edge support, which requires cutting and reinforcing work, and in addition to the cost required for this, various other indirect costs are required. shall be.

In view of the above-mentioned prior art, the present invention provides a metal fitting that connects a field edge support and a base material without requiring incisions or reinforcement of the ceiling base material, especially when incorporating a ceiling base material for air conditioning.

One embodiment of the present invention will be described in detail below according to the drawings.
In the figure, 1 and 2 are conventionally known field edge supports and field edges, and the field edge support 1 is a plurality of bolts hung at equal intervals on the ceiling construction surface by hanging bolts suspended from the roof girder material or the upper floor lower girder material. A large number of fences 2 are connected perpendicularly to the lower surface of the fence support 1 to form a ceiling base, and a ceiling board 3 is stretched over the fence 2. This is the same as before.

4 is a conventionally known ceiling base material for air conditioning, and a bottom plate 5 has a plurality of air outlets 6 arranged at equal intervals.

The entire length of the outer surface of the rising pieces 7 connected to both sides of the bottom plate 5 includes:
L-shaped protrusions 8 are provided to protrude so as to face each other vertically, and fitting grooves 8a and 8b are formed, and ceiling mounting pieces 9 are provided in series horizontally below both sides of the bottom plate 5 in the length direction. A chamber (not shown) is installed in this base material 4, and is connected to an air conditioner via a duct.

The present invention connects the field edge support 1 and the base material 4 orthogonally, and will be described in more detail.

The connecting fitting of the present invention, designated by the reference numeral 10, is made by punching out a single metal plate and integrally connecting a connecting piece 11 and a connecting plate 12 with an inclined plate 13, as shown in FIGS. , the connecting piece 11 is bent at right angles to the inclined plate 13 at the fold line a, and the vertical grooves 8 a , 8 b of the rising piece 7
The connection can be made by inserting the connection piece 11 into the
is larger than the distance between the upper and lower edges 8' and 8'' of the protrusion 8 of the rising piece 7, and it is difficult to fit into the grooves 8a and 8b from the side. When fitting the connecting piece 11 between the grooves 8a and 8b, the entire connecting fitting 10 is inclined as shown in FIG. Piece 1
The connecting piece 11 may be brought into contact with the side surface of the rising piece 7 so that the inclined surface 14 of 1 faces the upper and lower grooves 8 a and 8 b, and the fitting 9 may be rotated in the direction of the arrow shown in the figure. , 8. Even if it is possible to move along b, it will not be pulled out.

Incidentally, when removing the connecting pieces 11 from the grooves 8a and 8b, the procedure described above may be reversed.

A fixing piece 15 is connected to the top and bottom of the connecting plate 12 via a folding line to form a holding connecting part 16, and the fixing piece 15 is bent in the same direction as the connecting piece 11 at the folding line. Uke 1
is inserted between the upper and lower fixing pieces 15, and as shown in FIG.
Insert the bolt 18 into the screw hole 17 provided in the connecting piece 12 from the outside surface.
By screwing in, the field support 1 and the connecting part 16 are firmly connected.

The connecting fitting of the present invention has the above-mentioned configuration, and since the number and installation interval of the air conditioning base materials 4 are determined by the indoor space, the length of the field edge holder 1 can be regulated accordingly.
Since the distance between the field edge receiver 1 and the field edge receiver 1 is constant, the connecting fittings can be mass-produced with the same dimensions, and when the ceiling board 3 is used as a reference, the field edge receiver 1 has the field edge 2 interposed, so the base material 4 Although the position is higher, since the connecting piece 11 and the connecting part 16 are connected by providing a step above and below by the inclined plate 13, it is possible to sufficiently connect the field edge support 1 and the base material 4 which are in a high and low position.
