Planar roofing made of folded metal sheets
First Claim
1. A planar roofing made of folded metal sheets, which comprises a plurality of metal sheets in which two non-adjacent edges are complementarily folded so as to allow the coupling of two adjacent sheets by partial overlap, and a plurality of supporting retainer blocks, which can be anchored to a purlin for the roofing, wherein each supporting retainer block comprises a base portion for resting on the purlin, two lateral parallel portions that rise from the external part of the base portion, each lateral parallel portion having a cantilevered part so as to delimit a recess which is meant to accommodate a relatively deep fold or bend which is provided proximate to, and along, a folded edge of a respective metal sheet, each recess being inclined towards the respective raised portion by a preset angle, said supporting retainer blocks comprising furthermore an intermediate elevated portion which has a lateral recess that is directed towards each one of said recesses, runs parallel to them and delimits, in an upper region, a cradle which is meant to act as a support for a drainage channel delimited between two adjacent plates.

Abstract
A planar roofing made of folded metal sheets which comprises a plurality of metal sheets in which two nonadjacent edges are complementarily folded or otherwise shaped so as to allow the coupling of two adjacent metal sheets by partial overlap, and a plurality of supporting retainer blocks which can be anchored to a purlin for the roofing. Each supporting retainer block comprises a base portion for resting on the purlin and two lateral parallel raised portions that rise from the base and are individually externally flanked by a respective recess which is meant to accommodate a fold which is provided proximate to, and along, a folded edge of a respective metal sheet.
