Hereinafter, referring to the specific contents of the present invention based on the above components, first the first frame 10 is a configuration that binds the seam A together with the second frame 20, the vertical cross-section is connected to each other at right angles The first upper plate 11, the first side plate 13, and the first lower plate 15 having a substantially channel shape are formed.

In addition, the first frame 10 is formed by being bent upward from the end of the first upper plate 11 and the first contact plate 17 is formed to be bent upward from the end of the first lower plate (15). The first reinforcing plate 19 is further included.

The second frame 20 has a structure corresponding to the first frame 10.

That is, the second upper plate 21, the second side plate 23, the second lower plate 25, which are connected at right angles to each other, and have a longitudinal channel shape, and are bent upward from the end portions of the second lower plate 25. The second contact plate 27 is formed and the second reinforcing plate 29 is bent downward from the end of the second upper plate 21 is formed.

Here, the second reinforcing plate 29 is selectively provided according to product specifications.

The first lower plate 15 and the second lower plate 25 are in close contact with the bottom of the roof finishing panel and the seam A is disposed between the first and second contact plates 17 and 27. When the first frame 10 and the second frame 20 are bolted to the lower fastening holes 31 and 31 ′ of the fastening part 30 to be described later, the first contact plate 17 and the second contact plate 27 are In close contact with the seam (A) is made and at the same time the roof panel fixing of the frame coupling and connection fixing device is made.

8 is a front view showing an exaggerated lateral deformation, a lateral deformation (K) is generated when a lateral external force (P) is applied to the connection fixing device as shown in FIG. Due to the combination of the tension (T) and the bending moment (M) acts on the nut (N), this complex force repeatedly acts on the nut (N), the bolt loosening occurs.

Accordingly, when the frame is coupled, the first upper plate 11 and the first reinforcing plate 19 are tightly constrained to the inner corners of the second upper plate 21 and the second side plate 23, thereby restraining the first frame in the bolt fastening process. 10 and the second frame 20 serves as a jig for maintaining a proper posture, and also serves as a kind of reinforcing rib to suppress lateral deformation, thereby preventing bolt loosening.
