Roof assembly with corrugated sheets held to roof structure via plastic elements engaging grooves in sheets and spaced apart by openings in modular rails

摘要

A roof assembly consists of a roof structure defining a fall, and a plurality of roof cladding sheets attached to the roof structure via at least two rows of plastic members, the plastic members engaging in grooves in the cladding sheets, the grooves being perpendicular to the rows, so as to hold the sheets to the roof structure, wherein at least some of the plastic members are held to the roof structure, in each row via one or more openings in modular rails indexed to one another in series in the row, each plastic member interacting with an opening or openings.
