Description

Covering for roofs and the like

The inventors were assigned: mauro, MENEGOLI

Technical Field

The present invention relates to coverings for roofs and the like.

More specifically, the present invention relates to a covering for roofs consisting of a plurality of metal sheets, which are arranged adjacent to each other and joined along the lateral edges by means of joining elements to obtain a continuous surface that is easy and quick to assemble.

Background

In most construction and architectural solutions, there are currently coverings for roofs consisting of a plurality of metal sheets, which are arranged adjacent to each other to obtain a continuous surface that is easy to assemble and maintain.

More specifically, such a covering is constituted by a plurality of panels made of a metallic material, such as aluminum, copper or stainless steel, which have a length variable according to the dimensions of the roof and have lateral edges joined to each other at a joint fixed to the surface of the roof.

The use of such a cover may result in various advantages.

First, these covers are completely impermeable, also due to the provision of specific drainage paths.

Furthermore, the fixing of the panel to the roof is performed by the above-mentioned joints, not by perforations, so that the panel can be freely thermally expanded even in the case of lengths exceeding 100 meters.

Furthermore, since this type of covering allows to support the weight of a person, it can be easily stepped on (steppedon), it is easy and quick to assemble, is cheap and has characteristics and advantages that are not variable over time.

Last but not least, this type of covering allows the rapid assembly of solar panels or other similar elements on the roof by means of special coupling means.

This type of covering is described in the european patent EP0964114 by the applicant.

Although already effective in terms of the features outlined above, the covering described in this document presents some drawbacks with respect to the resistance to evenly distributed loads, such as snow, wind, or concentrated loads.

In particular, if the spacing between the fixing joints is greater than 1.8m to 2.0m, the covering can only be achieved by using plates with increased thickness, or reducing the pitch (pitch) between the ribs of the plates at the edges for fixing to the above-mentioned joints, but thus increasing the material used.

This leads to increased costs due to the use of greater amounts of material, which is generally not sustainable.

Disclosure of Invention

The technical task of the present invention is to improve the state of the art.

In this technical task, the covering for roofs and the like is provided that allows to overcome the above mentioned drawbacks, namely the possibility of supporting in a safe and reliable manner evenly distributed loads or concentrated loads, constituting the object of the present invention.

Another object of the present invention is to provide a covering for roofs and the like, which is: which can allow the plate to be assembled between the joint members arranged at a larger distance without having to increase the thickness or size of the rib portion by increasing the use of the metal material.

These tasks and objects are achieved by a covering for roofs and the like according to the appended claim 1. The dependent claims relate to preferred and advantageous embodiments of the invention.

Detailed Description

With reference to fig. 1, a covering for roofs and the like according to the invention is indicated as a whole by 1.

The covering 1 according to the invention can be applied efficiently on any type of roof without any restriction, even roofs of very large dimensions and with uneven surfaces are suitable, since the present covering 1 can also be applied to curved roofs.

The covering 1 according to the invention comprises at least one engaging element 2, which engaging element 2 can be fixed to the surface of the roof.

More specifically, the covering 1 generally comprises a plurality of engaging members 2 arranged aligned in rows and spaced apart at intervals, as shown in fig. 1.

The number of rows of engagement members 2 required to obtain a given roof covering 1 obviously depends on the dimensions of the roof and its specific characteristics.

The joint 2 comprises a first portion 3 and a second portion 4, which are opposed.

In more detail, as can be clearly seen in particular in fig. 4, the first portion 3 and the second portion 4 are symmetrical with respect to an imaginary plane of symmetry of the joint 2.

The first portion 3 of the joint 2 comprises a first upper appendix 5, the first upper appendix 5 defining a first lateral recess 6.

In particular, the first recess 6 is defined by a curved end portion of the first appendix 5.

Furthermore, the second portion 4 of the joint 2 comprises a second upper appendix 7, the second upper appendix 7 defining a second lateral recess 8.

In particular, the second recess 8 is defined by a curved end portion of the second appendix 7.

The first part 3 of the engaging member 2 further comprises a third recess 9.

The third recess 9 is defined by a first lateral area 10 of the engaging member 2, which is inclined towards the centre line of the engaging member 2.

The second portion 4 of the engaging member 2 comprises a fourth recess 11.

The fourth recess 11 is defined by a second lateral area 12 of the engaging member 2, which is inclined towards the centre line of the engaging member 2.

The cover 1 comprises at least a first plate 13.

Furthermore, the cover 1 comprises at least a second plate 14.

The first plate 13 comprises at least a respective first lateral edge 15.

The second panel 14 includes at least one corresponding second lateral edge 16.

The first plate 13 and the second plate 14 can be coupled to the joint 2 by respective first lateral edges 15 and second lateral edges 16 to obtain a continuous surface, as better clarified in the following, as shown in fig. 1 and in the detail of fig. 4.

The above-described assembly constitutes the basic element of the cover 1, i.e. said element comprises a minimum number of components.

Obviously, this basic element can be replicated an infinite number of times identically to itself to obtain a freely extending covering surface, as better illustrated hereinafter.

The first lateral edges 13 define respective first longitudinal ribs 17.

In more detail, such first lateral edge 13 can be coupled fittingly to the first portion 3 of the joint 2 to engage the above-mentioned first rib 17 inside a corresponding first recess 6 provided in the first portion 3 of the joint 2.

Meanwhile, the second plate 14 comprises a respective second lateral edge 16 defining a second longitudinal rib 18.

The second lateral edge 16 can be fittingly coupled to the second portion 4 of the joint 2 to engage the above-mentioned second rib 18 within a corresponding second recess 8 provided in the second portion 4 of the joint 2.

Furthermore, the second lateral edge 16 comprises an end portion 19, which end portion 19 in the assembled state overlaps the first lateral edge 15 substantially at the centre line of the joint 2.

According to an aspect of the invention, the terminal portion 19 of the aforementioned second lateral edge 16 comprises an extension 20, this extension 20 having a free end 21 folded and engaged in the first rib 17 of the first lateral edge 15.

As can be observed in the following description, this feature allows to increase the resistance of the covering 1, in particular at the junction 2, to both distributed loads, such as snow, wind, and concentrated loads.

The first lateral edge 15 of the first plate 13 also comprises a third rib 22.

The third rib 22 is provided in a region included between the flat portion 23 of the first plate 13 and the first rib 17.

The third rib 22 is configured for engagement in a third recess 9 provided in the first part 3 of the engagement member 2.

The area comprised between the first rib 17 and the third rib 22 can be used for fixing elements such as solar panels or the like by means of specific coupling means not shown in the figures.

And the second lateral edge 16 of the second panel 14 includes a fourth rib 24.

The fourth rib 24 is provided in the area comprised between the flat portion 23 of the second plate 14 and the second rib 18.

The fourth rib 24 is configured for engagement in a fourth recess 11 provided in the second portion 4 of the engagement member 2.

As previously mentioned, the area comprised between the second rib 18 and the fourth rib 24 may be used to fix elements such as solar panels or the like by means of specific coupling means not shown in the figures.

The terminal portion 19 of the second lateral edge 16 is configured to form substantially an "M" shape in cross-section.

The second rib 18 and the folded free end 21 are respectively provided at the distal end portions of the above-mentioned "M" shape, thereby defining a substantially symmetrical configuration with respect to an imaginary centerline plane of the joint 2.

While the first lateral edge 15 is configured to generally form a recumbent "S" shape in cross-section, as can be seen in detail in fig. 4.

The first lateral edge 15 comprises: a first portion 25 having a shape complementary to that of the second lateral edge 16, and a second portion 26 which is free and i.e. not intended to be coupled to another surface.

As can be observed in fig. 4, the respective configurations of the terminal portions 19 of the first lateral edge 15 and of the second lateral edge 16 are such as to ensure an accurate superimposition between these portions, which ensures a continuous covering surface avoiding the penetration of water or foreign bodies.

Thus, as previously mentioned, the coupling of the first plate 13 and the second plate 14 to the joint 2 defines the basic elements of the covering 1 according to the invention that have been described in detail so far.

As previously mentioned, the covering 1 according to the invention may be constituted by a plurality of first 13 and second plates having a predetermined length and coupled to the engaging members 2 positioned in one or more rows and regularly spaced with respect to each other, so as to obtain a continuous surface.

Thus, in a preferred embodiment, the covering 1 comprises: a plurality of joints 2 arranged in rows and equally spaced from each other, and a plurality of first plates 13 and second plates 14 coupled to the joints 2 in an alternating manner, as shown in fig. 1.

Obviously, the size and number of plates 13, 14 may vary according to the needs of a particular application.

In the preferred embodiment of the invention shown in the figures, each first plate 13 and each second plate 14 comprises respectively a first lateral edge 15 and a second lateral edge 16, which are opposite.

This is for example as shown in fig. 2.

This solution is particularly advantageous, mainly from an economic point of view, since it allows to obtain the covering 1 using a single type of panel.

Therefore, the first plate 13 and the second plate 14 are the same in this embodiment.

However, in other embodiments, the first plate 13 and the second plate 14 may be different from each other.

For example, the first plate 13 may be provided with two identical first lateral edges 15 and likewise the second plate 14 may be provided with two second lateral edges 16, or vice versa.

The first plate 13 and the second plate 14 of the cover 1 are made of a metal material, such as aluminum, copper, stainless steel, etc.

While each engaging member 2 of the cover is made of a plastic material.

It has thus been observed that the invention achieves the proposed objects.

In particular, it can be seen that the increase in mass at the second lateral edge 16 of the first plate 13 and/or of the second plate 14 contributes to an improved ability to withstand evenly distributed positive and negative loads; in more detail, a better ability to withstand snow loads and air discharges has been observed.

Furthermore, the engagement of the free end 21 of the second lateral edge 16 in the first rib 17 of the first lateral edge 15 achieves a better coupling between the two plates 13, 14, increasing the resistance to concentrated loads.

The above-mentioned advantages also allow laying the covering 1 on roofs where the coupling elements 2 are arranged at a mutual distance of more than 1.8 to 2.0 metres.

A greater distance between the joint parts 2 is also obtained which maintains the desired sealing properties against atmospheric agents.

A further advantage brought about by the engagement of the free end 21 of the second lateral edge 16 in the first rib 17 of the first lateral edge 15 is the fact that the first lateral edge 15 can bend downwards in any way under the action of an external load.

This allows preventing the coupling between the first lateral edge 15 and the second lateral edge 16 from opening, thus allowing ensuring a perfect seal against the penetration of air and water.

The invention has been described according to a preferred embodiment, however, equivalent variants are conceivable without departing from the scope of protection provided by the appended claims.
