Abstract

A quadrilateral roofing tile wherein has two parallel sides present with their edges bent through 90° in opposite directions to engage under traction with a first adjacent tile by ribs and complementary seats, those edges are the seats being provided at their ends with apertures which can be superposed on portions of an adjacent second tile for engagement by roof fixing elements, and can be covered by that bent edge of the first adjacent tile which comprises the ribs.

Description

QUAD TILT FORMAT

The present invention relates to a tile.

Tiles made of plastic polymeric material are available in various forms and have high strength and excellent mechanical properties.

These tiles, which are alternatively substantially flat or in the form of a semi-cylindrical body provided with coplanar side flanges, are fixed to the overlapping roof relative to one another along one side edge or edge by means of a screw or a nail fixed through a hole suitably provided on its surface, which is then covered with a plug.

These known tiles, however, have certain disadvantages, and in particular:

- unreliable characteristics of water impermeability in the orifice region, which even being covered by the plug, in certain cases is not completely free of water infiltration,

- Shingles can rise and split twice as a result of gusts.

The object of the invention is to eliminate these disadvantages by providing a tile which is simultaneously reliably watertight and which can be reliably fixed to adjacent tiles. The objective is achieved by a quadrangle-shaped tile as claimed in claim 1.

A preferred embodiment of the present invention and a variant thereof are described in more detail below with reference to the accompanying drawings, in which:

Figure 1 is a perspective view of a tile according to the invention, top-down view,

Figure 2 "is an emperspective view of the same bottom-up view,

Figures 3, 4, 5 and 6 illustrate steps of tile assembly,

Figures 7 and 8 are plan views of a variant viewed from bottom to top and top to bottom, and

Figures 9 and 10 illustrate enlarged details of the coupling ends. As can be seen from Figures 1 and 2, the invention according to the invention has a substantially triangular shape with a smooth upper surface 2, and with its lower surface 4 comprising a plurality of promoter ribs 6. of rigidity.

In the description, the terms "lower" and "upper" are used to indicate the surface facing the roof and the surface facing the outside, respectively, and the terms "transverse" and "longitudinal" are used to indicate the directions respectively parallel and perpendicular to the runoff line.

The tile is curved downwardly at a 90 ° angle along a first edge to form a first flange 8, the inner surface of which comprises a plurality of appendages perpendicular to it, and which is curved upwardly at an angle of 90 ° to form. a second flange 12 comprising a plurality of slots 14.

The number of slots 14 corresponds to the number of

Appendices 10 and the geometric wheelbases are the same in both cases.

Along one of its longitudinal edges the upper surface of the tile comprises a depression that forms a rainwater drainage chute 16 provided with direct fall inhibiting ribs 1-18. The hook is also provided at the ends of the side which contains "the second flange with a bushing 20 and an appendix 22, which - allow the insertion of the screws or nails for fixing the tile to the roof.

Finally, the upper surface of the shingle has a rib 24 which together with the downwardly curved edge 28 forms one. trunking 16 complementary to trunking 16.

The tile according to the invention is applied to the

roof as described below.

A first tile is applied along the flow line such that the first edge 8 is substantially adjacent to the drain line and is then fixed to the roof by screws or nails inserted through the bushing 20. A second tile is then applied adjacent to the

preceding tile such that rail 28 is overlapped with rail 16 and appendix 22 and bushing 20 are mutually overlapping, thereby allowing the insertion of a second nail.

When the row has been completed, the tile that

The first to be fixed is overlaid by a detail tile so that its edge 8 rests on the surface (see Figure 4). Said tile is then pulled towards the ridge such that the appendages 10 fit into the slots 14 (see Figure 5). By virtue of this separation, the upper transverse edge of the lower tile is covered by the lower transverse edge of the overlapping tile, thereby hiding the appendages and bushings.

The tile fitted in this manner is then fixed in this configuration by inserting nails through the showerhead 20.

It should be noted that coupling between first row ribs (the sliding chute row) and those of the upper row can be obtained even if the tiles are misaligned, as the mutual arrangement of the appendages and slits allows varying degrees of misalignment depending on the number n. In the configuration illustrated in Figures 7 and 8, the tile comprises a semi-cylindrical body 30, the longitudinal edges of which extend two coplanar flanges 32.

The two flanges have the transverse edges 34 closest to the 90 ° angled curved chute line and comprise U-shaped ribs 38 for insertion into corresponding U-shaped seats 40 provided at the distal transverse edges 42 of the runoff line.

The shingles are provided with a bushing 44 and an appendix 46 for fixing them to the roof and have their upper surface provided with a rain drainage rail 48 which cooperates with a rail 50 present on its lower side.

The tiles of this configuration are also applied by applying a first tile to the long runner line with its edge 34 adjacent to the runner line, and subsequently fixing the tile to the roof by screws or nails that are inserted through the bushings. Also in this case a second tab is applied adjacent to the preceding tile such that rail 50 overlaps rail 48 and appendix 46 and bushing 40 mutually overlap to allow insertion of a second nail.

In the above description it is apparent that the tile according to the invention has numerous advantages, and in particular: it provides a reliable waterproofing feature in that the regions through which the inserted screws or stud are covered by the overlapping tiles,

Provides a reliable resistance-to-gust resistance as the tiles are prevented from rising in both directions due to the double, longitudinal and transverse insertion fit.
