<p>PROBLEM TO BE SOLVED: To provide a joint structure of a heat insulating roof panel eliminating notch work at a construction field and connecting the heat insulating roof panel at a joint section excellent in water-tightness by eliminating four thickness of heat insulating roof panel resulting in a highly uneven step to make the joint structure as a butt joint structure of two heat insulating roof panels. SOLUTION: A heat insulating roof is constructed by connecting a plurality of heat insulating roof panels 10, 20, 30 and 40 to each other in the horizontal direction and the direction of an eaves-ridge. An eaves side extension section 31a of the ridge side heat insulating roof panel 30 overlaps with the ridge side end section of the eaves side heat insulating roof panel 10, and metal-made face materials 11 and 21 do not overlap each other between the heat insulating roof panels 10 and 20 adjacent to each other in the horizontal direction. The heat insulating roof panel 20 is positioned to the heat insulating roof panel 10 by simple work for a fitting section 26 to fall in a receiving section 17. Favorably, a packing 7 is inserted into an opposing section to the receiving section 17 and the fitting section 26, and a batten seam 8 sticking a sealing compound 8a on the rear side is put on the opposing section.</p> |
