Abstract

A modular roofing element (1) consisting of a plate-like element of substantially rectangular shape in which one side edge (2) is bent frontwards to U-shape and is provided with a lower appendix (4) bent rearwards to U-shape, the other side edge (5) is bent rearwards to U-shape, and the upper transverse edge (7) is bent frontwards to U-shape.

Ref: 701 042 and the flaps of said edge 2 lie symmetrically with respect to the general plane of element 1; the left side lateral edge 5 is curved rearwardly U-shaped and is provided with a bore 6 corresponding to the right side side bore 3; the upper transverse edge is curved in the U-shaped front direction; although it is not strictly necessary to provide a continuous curvature along the upper edge 7, it is preferable because, as will be apparent hereinafter, this ensures a good seal against water and wind force, and also gives greater freedom in relative positioning of the various elements. However, the shortening of the edge 7 does not include the right side edge 2 or the other flap of the left side side edge 5; - the lower edge 8 has its ends slightly rounded and a slight curvature is given back. As will be apparent from this forward this slight curvature is provided by both aesthetic and functional razbes in which contributes to seal water and wind. The element according to the utility model is constructed from a strip of sheet metal, of which a portion corresponding to the developed element is punched without parts which are not present in the finished element, i.e. the lower portion of the The punch cut piece is then subjected to conventional machining operations to produce the element 1. This can then be surface treated if the initial sheet strip does not had undergone such treatment.

For mounting purposes, a grid-shaped support, advantageously of wood or possibly metal, is required, comprising a plurality of longitudinally disposed elements 9 parallel to each other, at a distance substantially equal to each other between the distance between those lines in the elements 1, around which the upper edge 7 and the lower edge 694

The lower left-hand cover member is then applied to this grid and secured to the corresponding longitudinal member 9 with screws, screwed through the holes 3 and 6 provided in the two side edges 2 and 5. the horizontally adjacent element is then secured to this element so that its rearwardly curved left side edge 5 engages the front curved right side edge 2 of this already fixed element, and is then secured to the same longitudinal element 9 with screws through the holes 3 and 6. When the horizontal row of the elements is complete, the overlapping row is started. The first member is applied in an imbricate arrangement between the two adjacent elements 1, positioned on the left side of the lower row, so that the hook-shaped attachment 4 of the right side edge 2 of the new element engages the edge transverse salt the upper one of the front curved portion 7 of one of said elements of the first row. This procedure is then repeated for the adjacent element until the second row is complete, after which the third row is applied and so on until the water in the roof is completed.

If the roof is two-watered, the upper two rows of elements 1 are connected to each other by the rigid elements 10 and 11 engaging the two curved upper edges 7 of the elements of these two rows, the rigid elements 10, 11 are then joined together both directly (see Fig. 6) or by the U-shaped section elements, 12 (see Fig. 7).

From the foregoing it is evident that the modular elements according to the utility model are extremely advantageous in that: They are extremely easy to assemble. - Allow the construction of roofs of great mechanical stability. - Provide an excellent seal against water and wind - read a pleasing appearance. - Make the roof virtually insensitive to thermal expansion by absorbing it completely. - Build roofs with excellent natural ventilation. 69 444 Ref: 701 042 A l-Ί // ^ /
