A combined structure of insulated panel is disclosed, consisting of a pair of metal sheets which enclose sandwich-like an insulating layer, and of relative attaching means, at least one of said metal sheets being corrugated and provided with ribbings with a cross-section forming undercuts for the engagement of said attaching means, wherein
the section shape of said ribbings is a geometric shape obtained from two equlateral trapetiums one above the other, the bottom one having a major base and with the slanting sides more convergent than the top one, between which an S-shaped fold forming at least an inner undercut recess is provided (6),
said attaching means are essentially in the shape of a fastening box-like body (25) from one side of which a pair of arms which can be elastically spread apart/moved closer together (26) projects and which can snap-engage with said undercut recess, the other side forming an anchoring element for a fastening clamp (27) of a covering and finishing metal sheet (F 1 ), and
said pair of arms (26) crosses the entire thickness of said panel (P) entering from a substantially flat metal sheet (1) of said panel and engaging with said inner undercut recess (6a). |
