Field of the Invention The present invention relates to an insulated roof panel constituting a building roof and a connection structure of the insulated roof panel. 2. Description of the Related Art Conventionally, roof panels of various shapes have been proposed from the viewpoint of the design of a roof, and as an example, a roof panel having an uneven surface or a flat surface. Known roof panels and the like are known, and an example of a construction method of these roof panels is shown in FIG. In the same figure, a plurality of heat insulating materials 90 are provided with a gap in the roof base material 9.
2 and the upper surface of the heat insulating material 90 is covered with a face plate 91 having a flat surface.
3a is inserted, and both ends of the hanger 93 are fixed to the roof base material 92 with fixtures 94.
An inner gutter 96 surrounding the concave groove 93a of the hook 93 is fixed on the roofing 95, and the upper part of the inner gutter 96 is covered with a joint cover 97. When the rain falls, the joint cover 9 is closed.
The rainwater entering through the gap 7 is drained to the outside via the inner gutter 96. [0003] However, in the conventional method of constructing the insulated roof panel 1 ", the entire surface of the roof panel 1" is formed flat, so that when the rainfall occurs, the insulated roof panel 1 "is not used. Rainwater flows under the same conditions as the surface of the insulated roof panel 1 "at the joint portion"", and since the joint cover 97 at the joint portion is recessed in a step-like manner, rainwater concentrates at the joint portion and flows into the inner gutter 96. The amount of water will increase. Particularly in the case of strong rain, the amount of water in the inner gutter 96 increases, and the rainwater overflows on the roof base material 92 side along the outer surface of the inner gutter 96 from the gap G between the upper end edge of the inner gutter 96 and the heat insulating material 90. Out of the building, causing a problem of rain leaking inside the building. Conventionally, a heat insulating material 90 is placed on a roof base material 92.
And the roof panel 1 ″ is laid on the heat insulating material 90. Therefore, there is a problem that the construction work is troublesome, and the roof panel 1 ″ is a long product. Even in this case, the joining in the width direction is necessary. Conventionally, the joining is performed by using the joints 97 and the inner gutter 96 which are separate from the hangers 93 and the roof panel 1 ″. [0004] The present invention has been made in view of the above-mentioned conventional problems, and has as its object to improve the watertightness of a fitting portion between a fitting concave portion and a fitting convex portion. Another object of the present invention is to provide an insulated roof panel and a connection structure thereof, which secures and reliably prevents rainwater from entering the inside of a building, and enables installation work on a roof base material with a small number of parts. However,
An object of the present invention is to provide an insulated roof panel capable of improving the appearance of a fitting portion between a fitting convex portion and a fitting concave portion. Still another object is to provide a structure in which rainwater flowing down from the panel surface is received by an eaves gutter. It is another object of the present invention to provide an insulated roof panel in which the eaves gutter can be installed easily and easily. [0005] In order to solve the above-mentioned problems, an insulated roof panel according to the present invention comprises a panel body 5 in which a heat insulating material 2 is filled between two metal shells 3 and 4.

At the same time, since the packing 15 is inserted in the gap 14, it is possible to prevent rainwater from entering as much as possible. This is the same regardless of whether the rib 6 is formed on the panel surface 5a or the case where the rib 6 is not formed. Therefore, the amount of rainwater leaking from the packing 15 and flowing down to the gutter portion 13 is much smaller than in the past. Further, the packing 22 is provided also in the gap 14 'between the fitting projection 9 and the fitting recess 10 outside the gutter portion 13.
