(54) | Folded sheet metal roofing structure |
(57) A folded metal sheet roofing structure, which comprises: a plurality of metal sheets
(33) with two non-adjacent edges (36, 37) complementarily folded or otherwise shaped
so as to allow mating of two contiguous metal sheets (33) by partial overlapping and
snap engagement; a plurality of supporting and holding blocks (1), which can be anchored
to a roofing purlin and have a base portion with two protruding raised portions (3,
4), each raised portion being externally flanked by a respective recess. One raised
portion of each supporting block (1) has a diverging inclination with respect to the
other and each one of the recesses is externally adjacent to an inclined-plane cradle
which is inclined toward a corresponding raised portion with its access delimited
by a shoulder or abutment tooth (11) on one side, and by inclined-plane surfaces at
the other side, thereby allowing the anchoring and quick overlapping coupling of one
metal sheet (33) with a contiguous one simply by applying pressure from above to cause
the metal sheet to slide on the inclined-plane surfaces. |
