Profile for ridge aeration in ventilated roofs

Abstract

 A profile for ridge aeration in ventilated roofs, characterised by comprising:
- two angular profiles (2), of contained angle greater than 90°, with substantially vertical parts (4) and with substantially oblique parts (6) provided with holes (8) for their fixing to the roof covering,
- two profiles (10) positioned external to the substantially vertical parts (4) of the angular profiles (2), said profiles consisting of a part (12) rigid with the oblique part (4) and of two perforated parts (14, 18) of different height, the end of that part (18) of greater height being secured to an inverted V-shaped cover (24).

Description

[0001] The present invention relates to a profile for ridge aeration in ventilated roofs.

[0002] Ventilated roofs are known, i.e. roofs in which the roofing tiles do not rest directly on the concrete filling, but are spaced therefrom by a plurality of slats to allow air movement.

[0003] This air movement, which begins at the gutter line and, caused by the solar heating effect, leaves at the highest part of the roof along the ridge line, preserves the roofing materials (roofing tiles) and the roof insulation, especially if of wooden construction.

[0004] Components to be applied along the ridge line have already been proposed, consisting of two horizontally extending parallel bands lowerly presenting roof fixing slots and upperly comprising air passage perforations, the upper edges of said bands being connected together by a metal cover plate of substantially inverted V-shape.

[0005] These components present however the drawback of possible water passage through the perforated part, especially in strong rainstorms, followed by descent into the ventilated region, leading to humidity in that region.

[0006] According to the invention, these drawbacks are eliminated by a profile for ridge aeration in ventilated roofs as claimed in claim 1.

[0007] The present invention is further described hereinafter with reference to the accompanying drawing, showing a perspective view of a profile for ridge aeration according to the invention.

[0008] As can be seen from the figure, the profile of the invention comprises substantially two angular profiles 2, of contained angle greater than 90°, with their vertical parts 4 parallel to each other and their oblique parts 6 provided with a plurality of holes 8 for their fixing to the concrete filling or wooden boarding.

[0009] Along the fold between the vertical parts 4 and the oblique parts 6 there are secured two further perforations 10 presenting a part 12 rigid with the oblique sides 6, a bent rim 14 comprising a plurality of perforations 16 and a further inner band 18 also comprising a plurality of perforations 20 and which is upperly bent to form a strip 22 to which the ends of a substantially inverted V-shaped cover 24 are fixed.

[0010] The profile is constructed of painted iron, plastic, stainless steel, copper, etc.

[0011] The upper ends of the vertical parts 4 of the profiles 3 are spaced from the cover 24 by a distance substantially corresponding to half the distance between the parts 4.

[0012] The profile of the invention is assembled in the following manner.

[0013] The two inclined bands 6 are firstly fixed by screws or nails along the roof covering in the ridge region. A traditional roof ridge can be applied to the profile fixed in this manner. Roofing tiles are then secured to the bent rim 14, to rest on the roof covering.

[0014] From the aforegoing it is apparent that the profile of the invention presents numerous advantages, and in particular:

• it prevents water from entering the space bounded by the two parallel bands 4 as any water which enters the interior through the perforations 20 is halted by the presence of the parallel bands 4 and made to again flow to the outside through the holes present in the bent region,
• it can be easily fixed by virtue of the presence of the holes 8.

Claims

1. A profile for ridge aeration in ventilated roofs, characterised by comprising:

- two angular profiles (2), of contained angle greater than 90°, with substantially vertical parts (4) and with substantially oblique parts (6) provided with holes (8) for their fixing to the roof covering,

- two profiles (10) positioned external to the substantially vertical parts (4) of the angular profiles (2), said profiles consisting of a part (12) rigid with the oblique part (4) and of two perforated parts (14, 18) of different height, the end of that part (18) of greater height being secured to an inverted V-shaped cover (24).

2. A profile as claimed in claim 1, characterised in that the parts (4) are vertical and mutually parallel.

3. A profile as claimed in claim 1, characterised in that the parts (14, 18) are mutually parallel.

4. A profile as claimed in claim 1, characterised in that the distance between the parts (4) of the profile (2) correspond to double the distance between the upper end of the part (4) and the cover.
