<p>A tile simulating four tiles having a reticulated mesh support and free assembly, which forms on a single piece two longitudinally superimposed ridge tiles and two adjacent channel tiles that are also superimposed and which are concave on the top face and have a flat support on the bottom face. The longitudinal side of the channel tiles has a flat area in an ascending oblique position. Both the concave area and the flat area on the bottom face have lugs with a trapezoidal section serving as support on the cover. The tile has a posterior peripheral ridge ending in an edge with a descending step at the height in which superimposition of the tiles is simulated. The flat area on the perimeter has a peripheral edge and other vertical ridges extending parallel to the edge and interrupted by oblique channels.</p> |
