DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. The connecting device 3 has a T-bar attachment plate portion 31 formed by bending one continuous metal plate piece at a right angle.
And the peripheral edge attachment plate portion 32. Both side plate parts 31, 3
The lower edges of 2 have different heights, and the difference is equal to the step of the peripheral portion of the regular type ceiling board used.

The T-bar attachment plate 31 is located at a position lower than the upper edge by a distance substantially equal to the height of the head 21 of the T-bar.
The individual movement preventing ridges 8A and 8B are formed at appropriate intervals. The ridges 8A and 8B are formed by a press working technique, which is generally called a "stringing process".

The width in the vertical direction of the peripheral edge attachment plate portion 32 is set on the peripheral edge 4 (of an aluminum extruded product) to be applied,
Is set equal to the distance between the lower insertion grooves 41A and 41B,
Further, at least one push-in locking claw 33 having a V shape is formed on a part of the upper edge thereof.

The state in which the T-bar 2 and the peripheral edge 4 are connected by the connecting device 3 is clearly shown in FIG. That is, the T-bar attachment plate portion 31 of the connecting device 3 is aligned with and in close contact with the vertical plate portion 23 of the T-bar 2, and the peripheral edge attachment plate portion 32 is aligned with and in close contact with the vertical plate portion 41 of the peripheral edge 4. , Between the upper and lower insertion grooves 41A and 41B.

In the peripheral edge adding plate portion 32, when the push-in locking claw 33 is pushed in the direction orthogonal to the vertical plate portion 41 of the peripheral edge, it is plastically deformed and extends upward to insert into the insertion groove 4.
1A inside, thus connecting device 3 and rim 4
And are firmly connected.

Further, in the T-bar 2, the fastening member 6 connects the T-bar 2 and the connecting device 3. The fastening member 6 is composed of a pair of plate pieces having a "U" -shaped recess formed in the middle thereof and a machine screw 7 for fastening them. "Ko"
The V-shaped concave portion is the head mounting portion 61, and one flat portion is the tightening portion 62. The other flat portion is a portion to be tightened with the machine screw 7. The tightening portion 62 presses the T-bar attachment plate portion 31 against the vertical plate portion 23 of the T-bar 2 between the movement preventing ridges 8A and 8B, and fixes the connecting device 3 to the T-bar 2.

As can be seen from the above structure, the coupling device 3 is fixed to the peripheral edge 4 by the cooperation of the insertion grooves 41A and 41B and the push-in locking claw 33, and is fixed to the T bar 2 by the fastening metal piece 6. In this case, the movement prevention ridges 8A, 8
Note that B reliably prevents movement or displacement of the T-bar attachment plate portion 31 along the T-bar 2. Thus T
The bar 2 and the rim 4 are firmly fixed, and there will be no misalignment between them even when an earthquake vibrates.

FIG. 3 shows a modified connecting device 13
This is applied to the peripheral edge 5 which is formed by bending a steel plate into an L-shaped cross section by roll processing. In this connecting device 13, in addition to the T-bar attachment plate portion 131 and the peripheral edge attachment plate portion 132, there is a ceiling plate receiving portion 134 orthogonal to this.
The difference in height between the upper surface of the ceiling plate receiving portion 134 and the lower end edge of the T-bar attachment plate portion 131 is equal to the step of the peripheral edge portion of the regular type ceiling plate used as in the case of the above-described embodiment. .

The manner of connecting the connecting device 13 and the peripheral edge 5 is shown in FIG. That is, as in the previous embodiment, the push locking claw 133 is pushed into the groove above the vertical plate portion 51 of the peripheral edge 5 to fix the peripheral edge 5. The connection between the connecting device 13 and the T-bar 2 is not shown, but it is exactly the same as in the case of the previous embodiment shown in FIG.

[0017]

As described above, according to the present invention, the mounting is very simple and the mounting work is easy.
In addition, since there is a height difference equal to the step of the regular type ceiling plate at the lower end edges of the T-bar attachment plate portion and the peripheral edge attachment plate portion, no skill is required during installation work. There is an advantage that you can get a beautiful finish.

According to the present invention, a further important effect is
Even if a vertical or horizontal vibration force is applied to each element that constitutes the ceiling, such as during a large earthquake, the T-bar and the peripheral edge are firmly connected to each other via a connecting device, and therefore the earthquake resistance There is an advantage that it has good properties and there is no fear of shifting at all, and therefore the aesthetics of the ceiling can be maintained at all times, especially when applied to a regular type ceiling panel.
