Accordingly, the locking edge portions 3 and 3 for supporting the ends of the ceiling plate p (see FIG. 17) are provided, and the wide locking ridge portion 2 is provided at the upper end of the main plate portion 4.

The ceiling plate suspension rods 1 and 1 are connected to each other in a T-shape. As shown in FIG. 2, the ceiling rods 1, 1, 1 are connected to the ceiling rods 1 and 1 at the same position on both sides of the ceiling rods 1 by connecting them in a T-shape. Are connected in a cross shape.

The connecting mechanism will be described. Figures 3 and 4
As shown in FIG. 2, one of the suspension rods 1 has a main plate portion 4,
Vertically long insertion holes 10 and 10 are formed adjacent to each other so as to communicate with each other. A regulation groove edge 11 is formed on the side edge of each insertion hole 10. Due to the insertion holes 10 and 10, the suspension rods 1 and 2 on one side of the main plate portion 4 and the suspension rods 1 and 2 on the other side, respectively.
The one end can be connected, and can have a cross-shaped connection configuration as described above.

On the other hand, a connecting plate 20 is fixed to the main plate portion 4 of each of the suspension rods 1 and 1 connected to both sides of the suspension rod 1 through the insertion holes 10 by screws 19 and 19, respectively. The connecting plate 20 is made of a metal plate made of steel or the like having a high spring property, and has a base plate portion 21 protruding from the end edge of the suspension rod 1 by an amount corresponding to the width W of the locking edge portion 3, and the base plate portion 21. A U-shaped connecting protrusion 22 protruding from the end edge e of the portion 21 is formed in series. As shown in FIGS. 5 and 6, the U-shaped connecting protrusion 22 includes a straight line portion 23 extending from an edge e of the base plate portion 21 and a folded portion formed by bending the straight line portion 23 by approximately 180 degrees. 24, and the insertion hole 10 and the vertical length are substantially equal to each other,
In addition, the distance t (see FIGS. 5 and 6A) between the front edge of the base plate portion 21 and the end edge f of the folded portion 24 is made substantially equal to the wall thickness of the main plate portion 4 of the suspension rod 1. Further, a regulation tongue piece 25 that is inserted into the regulation groove edge 11 projects from the center of the end edge f of the folded portion 24 . As shown in FIG. 6A, the folded-back portion 24 is formed in advance so as to be slightly expanded with respect to the straight portion 23.

Just press fit into 10. As a result, the folded-back portion 24 is pressed by both side edges of the insertion hole 10 and elastically deformed, becomes substantially parallel to the linear portion 23, and can be passed through the insertion hole 10. At the position where the end edge e of the portion 21 contacts the main plate portion 4, the restraint of the folded portion 24 by the insertion hole 10 is released, and the folded portion 24 returns to the expanded position. At this time, the restriction tongue piece 25 penetrates the restriction groove edge 11 (see FIG. 6B). Thus, at this position, the regulating tongue piece 25 has the regulating groove edge 11
The expansion of the folded-back portion 24 is restricted, and the restricting tongue piece 25 is held at the elastic contact position on the side edge of the restricting groove edge 11 to be in the connected state.

When a pulling force acts on one of the suspension rods 1, the end edge f of the folded portion 24 abuts the main plate portion 4 near the insertion hole 10 (see FIG. 6B). Therefore, since the U-shaped connecting protrusion 22 is constrained to be unseparable from the insertion hole 10 and the fold-back portion 24 is constrained from expanding by the regulation groove edge 11, it is The folded portion 24
Does not open outwards and deform. Further, in this configuration, in order to release the connection, the restricting tongue piece 25 protruding from the insertion hole 10 is moved by the driver or the like to form the linear portion 23.
Since the end edge f of the folded portion 24 is located in the insertion hole 10 and the constraint is released only by pushing in parallel with the U-shaped connecting projection 22, the U-shaped connecting projection 22 can be easily removed from the insertion hole 10. Therefore, the connection can be released easily.

As described above, this connection is made for the insertion holes 10, 10 which are adjacent to each other on both sides of the suspension rod 1, respectively. Therefore, as shown in FIG. 2, the suspension rods 1, 1, 1 are connected to each other. Becomes orthogonal.

9 to 11, 12 to 14 and 17, the restricting tongue piece 25 is replaced by the side of the insertion hole 10 instead of the restricting tongue piece 25.
The regulation projections 30a, 30b, 30c are formed so that the edge f of the folded-back portion 24 of the U-shaped connection projection 22 makes elastic contact with the surface direction. In this configuration, when the U-shaped connecting protrusion 22 is press-fitted into the insertion hole 10, the end edge e of the base plate portion 21 comes into contact with the side surface of the main plate portion 4 of the one ceiling plate suspension rod 1, and The end edge f of the folded-back portion 24 elastically comes into contact with the restriction protrusions 30a, 30b, 30c due to the expanding action. Therefore, there is no looseness in the width direction at the edge f of the folded-back portion 24, and even when a force in the pulling direction acts on the other ceiling plate suspension rod 1, the folded-back portion 24 has a slack. The edge portion f is held without expanding. That is, in the expanding and holding action, the same action and effect as those of the regulating tongue piece 25 described above are obtained.

9-11, the cutout hole 31 is formed at the side edge of the insertion hole 10 and the cutout hole 31 is bent at a right angle, so that the regulating projection 30a is orthogonal to the main plate portion 4. Is formed.

In addition, in FIGS. 12 to 14, the semicircular regulating projection 30b is formed by caulking the side of the insertion hole 10.
Are formed.

Furthermore, in FIG. 15, the semi-spherical caulking process is applied to the side of the insertion hole 10 so that the semi-spherical spherical restricting protrusion 3 is formed.
0c is formed.

In each of the above-mentioned structures, the U-shaped connecting projection 22 that can be press-fitted into the insertion hole 10 is formed by fixing the connecting plate 20 to the main plate portion 4.
As shown in, the base plate portion 21 and the U-shaped connecting projection portion 22 can be formed directly on the edge of the main plate portion 4 of the suspension rod 1. In this case, in order to improve the holding strength of the substrate portion 21, the reinforcing rib 32 is formed along the protruding direction of the substrate portion 21.

In each of the above-mentioned configurations, the regulating tongue piece 25 is connected to the folded-back portion 24 or the regulating projection 30 is formed.
Although the a, 30b, and 30c are provided so as to generate the expansion holding action, the restricting tongue piece 25 and the restricting protrusion 30 are provided by increasing the rigidity of the folded-back portion 24.
A configuration in which a, 30b, and 30c are omitted is also within the scope of the present invention.
