2. Description of the Related Art Conventionally, in a heat insulating panel 1, as shown in FIG. 6, fitting projections 6 are fitted to both ends of a panel body 5 in which a heat insulating material 2 is filled between front and back metal skins 3 and 4. The concave portion 7 is formed, and the heat insulating panel 1 adjacent to the surface side of the fitting concave portion 7
The cover 10 that covers the front surface side of the fitting convex portion 6 is provided so as to project, and the fitting convex portion 6 of the adjacent heat insulating panel 1 is provided on the rear surface side of the fitting concave portion 7.
Located on the rear surface side of the gap 1 between the fitting concave portion 7 and the fitting convex portion 6
The gutter portion 11 communicating with the gutter portion 2 is provided, and the mounting portion 13 for mounting the fitting convex portion 6 is provided at the panel end position rather than the gutter portion 11.

In the heat insulation panel 1 described above, however, the packing P ₁ is interposed between the fitting concave portion 7 and the fitting convex portion 6, and the fitting convex portion 6 is formed by the packing P ₁ and the cover portion 10. Rainwater is prevented from entering from the fitting portion between the portion 6 and the fitting concave portion 7, and the rainwater leaking to the back surface side through the packing P ₁ is received by the trough portion 11 and the back surface of the heat insulation panel 1 is received. The rainwater is drained to the outside through the trough portion 11 while suppressing its reaching to the side, and it is possible to reliably prevent the rainwater from entering the inside of the building.

A structure in which the adjacent heat insulation panels 1 and 1 are fixed by being locked to the wall surface 30 has been considered, but in the case where the retaining projection 31 is formed on the back surface of the fitting convex portion 6, it projects to the back surface. The retaining projections 31 which interfere with each other make it difficult to insert the fitting convex portion 6 into the fitting concave portion 7, and the work of connecting the heat insulating panels 1 and 1 is troublesome.

The present invention has been made in view of the above problems, and the work of compressing the interposing packing to a predetermined thickness and fitting and connecting it can be easily performed manually, and the packing A heat insulating panel and its connecting structure that can avoid the fluctuation of the amount of compression, can easily compress to a predetermined thickness, can maintain a sufficient watertight function for a long time, and can easily perform connection work. The challenge is to provide.
