PROBLEM TO BE SOLVED: To solve the problems of conventional connected roofs wherein, since a groove is formed in the surface thereof and it is extremely difficult to bond a heat insulating material thereonto, the heat insulating material is not bonded, but fixed with a screw, since the insulating material is fixed to a tight frame utilizing the groove, the fixing cannot be performed unless the tight frame is formed straight, and since the portion of the groove is present in the surface, water droplets are accumulated in the groove portion, and the heat insulating material is cracked due to the groove during the operation. SOLUTION: The lower surface of a recessed part 6 for fitting a leg-like rib part, formed on the tight frame 5 is mounted on a skeleton 8 by a predetermined mounting means. The leg-like rib part 1 of a roof board A is fitted into the recessed part 6 for fitting the leg-like rib part. A recessed/projecting part for fitting the roof board formed on the tight frame 5 is fitted and integrally mounted on the roof board A between the leg-like rib parts 1. The heat insulating material is bonded to the flat roof board. COPYRIGHT: (C)2007,JPO&INPIT
