<p>In this panel formed from an outer metal sheet (1) and an inner metal sheet (2), enclosing an inner mass (3), for example rigid foam, support surfaces (7, 22) of the upper metal sheet, intended to interact with those of the upper metal sheet of adjacent panels, form, with the plane of the panel, an angle (A) greater than that (B) made by the support surfaces (24, 26) of the lower metal sheet, this arrangement making one edge of a panel form a sort of bead which is held in a groove with a widened base of the widened panel, preferably with elastic interlocking. The flange (wing) (19) which carries one of the support surfaces of the upper metal sheet may also cover the fastening means (12) of the adjacent panel. <IMAGE></p> |
