To provide a coupling construction for fire-resisting roof having a light weight and maintaining fire resistance at the coupling portion due to deformation under a high temperature condition.
In connecting together a fire-resisting roof panels P by integral forming of a pair of surface plates 1 formed by aluminum members respectively, a frame member 10 interposed between side members of both the surface plates 1, and a core member 2 interposed in a space formed by both the surface plates 1 and frame member 10, a linking groove 15 opening to the outer side and a stripe 14 projected outward are formed at the frame member 10, a coupling member 18 having fire resistance linked to the inside of a linking groove 15 is erected between both the coupled panels P, and a backup member 19 straddled between the projected stripes 14 of both the panels P is received by the back, and a fire resisting seal material 9 is filled between both the panels P. In this way, the fire resistance of the coupling portion (joint portion) of both the panels P in a high temperature condition during a fire can be maintained.
