TECHNICAL FIELD The present invention relates to a roof connecting structure that is connected via a roof receiving frame, and particularly relates to its rain shunting.

[Conventional technology]

BACKGROUND ART Conventionally, a roof connection structure is known in which the ends of two roof plates are connected to a roof support frame (for example, SAIKAISHO).
60-130927 publication). This is shown in FIG.

In FIG. 6, a roof support frame 80 is fixed to the base material 100. The roof receiving frame 80 includes a first frame member 81 fixed to the base material 100 and the first frame member 81.
It comprises a second frame member 82 fixed by fasteners 83.
The second frame member 82 is formed with a protruding piece portion 84 that protrudes outward from a diagonally downward direction from above. One end portion 70 of the first (left) roof plate 7 extends a rising portion 71 that rises obliquely upward along the roof receiving frame 80, and both frame members 81, 82.
A bag-shaped portion 72 is formed by folding back along a recess 85 formed between them, and the bag-shaped portion 72 is further extended and folded back upward to form an engaging portion 73. The other end 90 of the second (right) roof plate 9 horizontally extends a rising portion 91 that rises obliquely upward along the roof receiving frame 80, and the roof receiving frame 80
It has an engaging portion 93 which covers the upper part of the above and further falls to the oblique lower side, and the fall portion 92 is folded back to engage with the lower portion of the engaging portion 73 of the one roof plate 7. The engaging portion 93 is further extended to form a closing portion 94 that abuts the bag-like portion 72 of the one roof plate 7 to close the gap between the roof plates 7 and 9.

[Problems to be Solved by the Invention]

By the way, in the above-mentioned prior art, both roof plates 7 and 9 are manufactured by roll molding of a metal plate, and for example, due to variations in the thickness of the metal plate or variations in the diameter of the molding roll itself in the longitudinal direction. Due to this, it is inevitable that the closing portion 94 and the engaging portions 73, 93 that close the gap between the roof plates 7 and 9 are corrugated along the longitudinal direction to form the gap.
Moreover, when a strong wind pressure acts from the direction of arrow A in FIG. 6 due to storms or the like, the rising portion 71 of the first roof plate 7 is pushed and deformed by the wind pressure, and the gap of the closing portion 94 becomes large. May be. Therefore, when a strong wind pressure acts from the direction of the arrow A, rainwater enters the bag-shaped portion 72 due to the blowing of the wind through the gap generated in the closing portion 94 and the capillary phenomenon. Although the wind pressure reaching the bag-shaped portion 72 is somewhat weaker, the atmospheric pressure is still higher than that indoors.
Due to the blowing of the wind through the minute gap between 3, 93 and the capillary phenomenon, it penetrates into the inner surface of the falling portion 92 of the second roof plate 90 and the tip of the engaging portion 73 of the first roof plate 7. Water drops will accumulate in the area. Further, the engaging portion of the first roof plate 7
The water droplets collected at the tip portion of 73 are guided by the wind that enters through the minute gap between the engaging portions 73 and 93, as shown by the dotted arrow in FIG. The second frame member 82 after being blown to the space below
Flowing along the upper surface of the roof receiving frame 80, and both end edges of the roof receiving frame 80 in the longitudinal direction and the first frame member 81 and the second frame member 82.
It will be dropped indoors along the insertion hole 86 of the fastener 83 for fixing and. In the roof connecting structure of the prior art shown in FIG. 6 as described above, in a storm or the like, rainwater easily intrudes indoors due to wind pressure and a capillary phenomenon, and the rain leak preventing function cannot be reliably achieved. was there.

The present invention has been made in view of the above circumstances, and can prevent rainwater from entering as much as possible during a storm, and moreover, for example, even if a part of rainwater enters, the infiltrated rainwater is collectively drained to indoors. It is an object of the present invention to provide a roof device and a roof connecting structure capable of reliably preventing intrusion.

[Means for Solving the Problem] A first invention is a first invention having an upward rising portion at one end.
