となった。To solve the above problem, a construction method of laying a heat insulating inclusion and a waterproof sheet with a heat insulating layer on the outer surface of a metal roof has been proposed (Japanese Patent Laid-Open No. Sho 62-62).
182154). However, in this construction method, since the fastening bolts for attaching the metal roof to the eaves girder protrude from the upper surface of the insulating sheet or the waterproof sheet with the insulating layer, rainwater or the like intrudes from the fastening bolt insertion holes, and the painted metal plate Became the cause of corrosion.
