    [0001] The object of the present invention is a roof and a method for making a roof. In the following discussion we will refer in particular to roofs made with stone slabs. This specific reference is given by way of non-limiting example and a skilled person can immediately understand how the invention can also be used in other similar fields.
    [0002] Covering roofs with stone slabs is a traditional solution in the construction sector, especially in some geographical areas where suitable stones are available for this purpose. There are several rocks, called schists, naturally suitable for making slabs. These rocks are traditionally used for this purpose because they are easily fracturable along parallel planes in order to obtain the desired slabs.
    [0003] In more recent times it has also emerged the use of cutting rocks by means of diamond cutters or blades, so as to obtain the slabs independently of any weak planes of the rock. These slabs, called sawn, milled or flamed, are much smoother than those with natural split.
    [0004] The stone roofs determine a marked characterization of the anthropic landscape in the areas where their use is traditionally widespread. In these areas, therefore, an attempt is made to maintain this use also for new buildings and following any renovations, so as not to alter the traditional landscape.
    [0005] Some salient features of traditional stone roofs are described below with specific reference to figures 1, 3 and 7 attached hereto.
    [0006] A known type of stone roof 10 comprises a structure 12, usually made of wood by means of joists (parallel to the direction p of the slope of the roof) and strips (parallel to the direction c of the eaves line). A covering 20 is superimposed on the structure 12 made by means of a plurality of plates 22 arranged in successive courses 24 partially overlapping one another.
    [0007] Each slab 22 of a course 24n is leaning against a slab 22 of the underlying course 24n-1 and to a strip of the structure 12. In a per se known way, the slabs can be fixed to the respective strips by means of nails or metal brackets. By way of illustration, the plate 22 shown in Figure 3 shows both the holes necessary for fixing by means of the nails, and the grooves necessary for fixing by means of the brackets.
    Traditional stone roofs, however, while widely appreciated, are not free from defects.
    [0009] First of all, the stone slabs 22 cannot be too thin, since they must resist atmospheric agents and the mechanical stresses to which they are subjected, both in the processing stages and during their operating life. The high thickness naturally determines a high weight of each individual slab 22.
    [0010] Furthermore, the sawn, milled or flamed stone slabs are substantially flat and smooth. For this reason, in the area where a slab rests on the slab below, the phenomenon of rising rainwater by capillarity occurs. In other words, when it rains, although most of the water flows from a slab to the slab below following the direction p of the slope of the roof 10, a small part of it rises, against the force of gravity, insinuating itself into the contact zone between the two stone slabs. To avoid that the rising by capillarity involves water infiltrations in the cover 20, some precautions are traditionally necessary.
    [0011] The first expedient is to keep the slope of the upper roof 10 at a minimum angle of about 25 ° equal to about 47%.
    [0012] The second expedient is to superimpose two successive courses 24n and 24n + 1 for a very extended portion, typically for more than half the length of the slabs 22. In figures 1 and 7 it is clearly seen how the first course 241 is covered for a large portion from the second course 242 which immediately follows it and as it is further covered for a small portion by the third course 243. Since three courses of slabs overlap each other repeatedly, this type of installation is also called "triple covering" .
    [0013] The triple covering, necessary in the case of smooth sheets (cut, milled or flamed) to avoid water rising by capillarity, is traditionally also used in the case of natural split sheets, although these do not involve any problem of capillarity . In fact, the triple cover also avoids water infiltrations along the lateral joints between two side-by-side slabs. As can be seen in Figures 1 and 7, the lateral junction between two side-by-side slabs of any course (for example the second course 242) is almost completely covered by the median zone of a slab of the upper course (in this case the third course 243 ) and, in the uncovered portion, rests on the median zone of a slab of the lower course (in this case the first course 241).
    [0014] Ultimately, therefore, the triple covering, which is necessary to guarantee the tightness of the covering 20, implies the use of many stone slabs 22 per unit of surface to be covered.
    [0015] As the skilled person can well understand, the high thickness of the slabs, the high slope and the high number of slabs per surface unit are all factors that combine to make it necessary to use a large amount of stone . This results in a high weight and cost for the roof 20. Furthermore, the weight of the stone roof 20, which by far exceeds the weight of other types of roofing available, usually translates into a higher cost also for the construction of the structure 12.
    [0016] The object of the present invention is therefore to overcome the drawbacks highlighted above in relation to the known art.
    [0017] In particular, an aim of the present invention is to make available a roof and a method which, for the same surface to be covered, make it possible to use a smaller quantity of stone than for traditional laying.
    [0018] Furthermore, a task of the present invention is to make available a roof and a method which, while using less stone, allow not to worsen or improve the performance of the roof with respect to traditional solutions.
    [0019] Finally, a task of the present invention is to make available a lighter and cheaper stone roof than the traditional ones.
    [0020] This object and these tasks are achieved by means of a roof according to claim 1, and by means of a method for making stone roofs according to claim 9.
    [0021] In order to better understand the invention and appreciate its advantages, some exemplary and non-limiting embodiments thereof are described below, with reference to the attached drawings, in which:

    [0032] Figures 11 schematically show some accessories according to the invention, in views similar to those of Figures 9 and 10.
    [0033] In the attached figures, the reference 10 generally indicates a roof comprising a structure 12 and a cover 20.
    [0034] In the following discussion, specific reference will be made to a wooden structure 12 and a stone roof 20. In particular, with the term stone, we refer below both to natural stone, whether split or cut, as well as to reconstructed or artificial stone. Furthermore, this reference is given by way of non-limiting example and the skilled person can immediately understand how the invention can also be used in the context of other similar constructive solutions.
    [0035] In the following discussion, reference will be made to the width and length of the sheets 22 and of the accessories 30. By convention here it is meant that the width is the dimension intended to be oriented in the direction c of the eaves line of the roof. According to the same convention, length is meant to be the dimension intended to be oriented in the p-direction of the slope. As the person can well understand, the slope of the roof 10 and the slope of the single slab 22 are different directions. However, for the purposes of this discussion it is not considered necessary to distinguish them since they differ only in the inclination with respect to the horizontal plane, both being perpendicular to the direction c of the eaves line.
    [0036] The invention relates to a roof 10 comprising a structure 12, a cover 20, and a plurality of accessories 30, in which:the structure comprises joists parallel to a direction p of the slope of the roof, and battens parallel to a direction c of the eaves line;the roof comprises a plurality of plates 22 juxtaposed to each other in direction c to form successive courses 24n, 24n + 1 ... partially overlapping each other in direction p.
    [0037] Each accessory 30 comprises:a lower bearing portion 301;a first upper resting area 302; Anda second upper resting area 304; in which:the accessory 30 develops mainly in a π plane;the accessory 30 defines a channel 300 suitable for providing a continuous sliding surface; Andin the direction perpendicular to the plane π, the lower bearing area 301 is spaced from the two upper bearing areas 302, 304 by a distance d comprised between 4 mm and 10 mm.
    [0038] Each accessory 30 is positioned in such a way that:the lower support portion 301 rests on a central area of a plate 221 of a lower course 24n and on a strip of the structure 12;the first upper support portion 302 supports a first slab 222 of an upper course 24n + 1;the second upper support portion 304 supports a second slab 224 of the upper course 24n + 1; Andthe channel 300 is subjected to the lateral juxtaposition zone 220 between the two plates 222, 224 of the upper course 24n + 1.
    [0039] In the roof 10 according to the invention:the two plates 222, 224 of the upper course 24n + 1 are spaced from the plate 221 of the lower course 24n by a distance d between 4 mm and 10 mm in the direction perpendicular to the plane π; Andthe plates of the upper course 24n + 1 are superimposed on the plates of the lower course 24n for less than half the length of the latter in the direction p of the slope of the roof 10.
    [0040] Here and below, the accessory 30 is defined in relation to a plate 221 of a lower course 24n on which it rests and in relation to two plates 222 and 224 of an upper course 24n + 1 which rest on the accessory 30 same. Naturally, as the skilled person may well understand, each slab 22 of the cover 20 can play different roles at the same time, when it is considered in relation to the accessory on which it rests or when it is instead considered in relation to the accessory it rests on. superimposed.
    [0041] In the following discussion it is considered that the accessory 30 is made by bending a metal sheet. As the skilled person may well understand, in principle the accessory 30 can also be made by means of other systems and with other materials. In principle, the accessory could be obtained by cutting to size sections of an extruded profile, made of metal or polymeric material. However, the applicant has noted that the production by bending of a metal sheet is particularly efficient. In fact, the accessory 30, being intended to be part of a stone roof, must be guaranteed for an operational life of several decades. For this purpose it is preferable to use copper, galvanized steel, aluminum or lead, as these materials are traditionally used for these uses. On the contrary, other materials, such as polymeric ones, could easily degrade under the combined effect of bad weather and the weight of the plates. Furthermore, since the accessory has a mainly flat development, the use of a sheet metal is particularly advantageous.
    [0042] As can be seen in the attached figures, the extension of the accessory 30 in the plane π is defined on the basis of the dimensions of the slabs 22 with which it is intended to be laid. As already mentioned, the length l of the accessory 30 is the dimension intended to be arranged parallel to the slope p of the roof 10. The accessory 30 has a length l which is slightly shorter than that of the slabs with which it must be laid. As can be seen in figures 2 and 8, the accessory 30 is slightly shorter than the slabs 22, so as to rest on the back of the same strip on which the slabs rest and, at the same time, so as not to protrude from the front and remain covered by the plates themselves. In particular, the length 1 of the accessory 30 can advantageously be comprised between 85% and 99% of the length of the plates 22.
    [0043] Again, the width w of the accessory 30 is the dimension intended to be arranged parallel to the eaves line c of the roof 10. Incidentally, the width w of the accessory 30 can also be seen as the distance between the two portions upper supports 302 and 304. The accessory 30 has a width w sufficient to include the entire lateral juxtaposition area 220 between the two upper plates 222 and 224 superimposed on the accessory 30. As the skilled person can well understand, the more the plates 22 have regular sides, the more circumscribed the juxtaposition zone will be and, conversely, the more the plates 22 have irregular sides, the wider the juxtaposition zone will be. In the case of sawn slabs 22, the lateral juxtaposition zone 220 will be little more than a line. On the contrary, in the case of split slabs 22, the lateral juxtaposition zone 220 will be a band a few centimeters wide. In order to meet specific needs, the width w of the accessory 30 can be between 5 cm and 25 cm, preferably between 10 cm and 15 cm.
    [0044] The lower support portion 301 can take different shapes in the various embodiments of the accessory 30 according to the invention. With reference to Figures 5, 6, 9, 11.a and 11.b, the lower support portion 301 can take the form of a flat area extending parallel to the plane π. With reference to Figures 4, 10, 11.c and 11.d, the lower support portion 301 can take the form of one, two or three edges, formed for example by the edges and / or folds of the sheet metal. The edges as a whole will be made in such a way as to define a plane substantially parallel to the π plane.
    [0045] Similarly, the upper supporting portions 302 and 304 can take different shapes in the various embodiments of the accessory 30 according to the invention. With reference to Figures 5 and 11.a, each of the upper supporting portions 302 and 304 can take the form of a flat band, obtained for example by bending the sheet metal. With reference to figures 4, 6, 9, 10, 11.b, 11.c and 11.d, each of the upper supporting portions 302 and 304 can take the form of an edge, formed for example by edges and / or folds of the sheet metal. The upper supporting portions 302 and 304 as a whole will be made so as to define a plane substantially parallel to the plane π.
    [0046] As already reported above, considering the direction perpendicular to the plane π, the lower support portion 301 is placed at a distance d from the two upper support portions 302 and 304. The distance d, being greater than 0, implies a interruption in the support between the plates 22 of two successive courses 24n and 24n + 1, and it is therefore the technical characteristic of the accessory 30 which allows to solve the problem of rising water by capillarity.
    [0047] Furthermore, the distance d introduced between two successive courses 24 of sheets 22 allows the roof 10, once finished, to be ventilated. The ventilation of the roof 10 is particularly advantageous when the structure 12 is made of wood. In fact, as the skilled person can well understand, despite all the precautions it may still happen that some humidity infiltrates under the covering 20. If this humidity were to stagnate on the wooden structure 12, it would end up ruining and weakening it. On the contrary, a correct ventilation prevents the stagnation of humidity and thus favors the maintenance of the wooden structure 12 at its best.
    [0048] The distance d should preferably be such as not to alter the overall appearance of the roof 10 once the stone roof 20 has been laid. In light of the above considerations, the distance d can be between 4 mm and 10 mm.
    [0049] As mentioned above, the accessory 30 defines a channel 300 suitable for providing a continuous running surface, typically for rainwater that must be drained from the roof 10. As regards the channel 300, the considerations made apply above for the width w of the accessory 30. The channel 300 is in fact the characteristic of the accessory 30 which allows the water that percolates to flow into the lateral juxtaposition area 220 between the two upper plates 222 and 224. The water that flows into the channel 300 is then conducted along the direction p of the slope up to the lower slab 221.
    [0050] The different embodiments of the accessory 30 represented in the attached figures have specific characteristics which suggest their use in different conditions. For example, the accessories 30 in which the lower support portion 301 takes the form of a flat area (see figures 5, 6, 9, 11.a and 11.b) are particularly suitable for use with naturally split slabs 22 , since in this case the problem of rising water by capillarity does not arise. On the contrary, the accessories 30 in which the lower support portion 301 takes the form of one, two or three edges (see Figures 4, 10, 11 and 11.d) are particularly suitable for use with cut slabs 22 , milled and / or flamed, since in this case the problem of rising water by capillarity arises, a problem that is solved by limiting the support to the edges only.
    [0051] The embodiments schematized in figure 11.a, in which the upper supporting portions 302 and 304 are obtained by multiple bending of the sheet, are particularly suitable for the case in which the accessory 30 is made of a relatively yielding material such as lead or copper. In this case, in fact, any crushing of the accessory 30 due to the weight of the plates 22 does not cancel the distance d.
    [0052] The embodiments schematized in figure 11.d are the most economical and rapid to implement since they require only one fold of the sheet. However, having only one lower support portion 301 with linear development, these embodiments do not guarantee the balance of the support on the lower slab 221 and therefore require particular care during the installation step.
    [0053] In accordance with some embodiments, the accessories 30 may comprise means for fastening to the structure 12. As widely appreciated for the sheets 22, the fastening to the structure 12 prevents unwanted sliding of the roof elements 10 in the direction of the slope p, even under the effect of loads such as wind and snow. The means for fixing the accessory 30 (not shown in the attached figures) can comprise holes for the application of nails and / or a fold parallel to the eaves line c for anchoring to a strip.
    [0054] The invention relates to a roof 10 comprising a structure 12 and a cover 20 comprising a plurality of plates 22. The roof 10 according to the invention further comprises a plurality of accessories 30 as described above.
    [0055] In accordance with some embodiments of the roof 10 according to the invention, in which the slabs 22 are laid sideways side by side to form successive courses 24, each accessory 30 is laid in such a way that:the lower support portion 301 rests on a central area of a plate 221 of a lower course 24n and on a strip of the structure 12;the first upper support portion 302 supports a first slab 222 of an upper course 24n + 1;the second upper support portion 304 supports a second slab 224 of the upper course 24n + 1; Andthe channel 300 is subjected to the lateral juxtaposition zone 220 between the two plates 222 and 224 of the upper course 24n + 1.
    [0056] Again, in accordance with some embodiments of the roof 10 according to the invention, each slab 22 rests on a first upper support portion 302 of a first accessory 30 and on a second upper support portion 304 of a second accessory 30. Furthermore, the lateral juxtaposition area 220 between two plates 22 is superimposed on the channel 300 of an accessory 30.
    [0057] As mentioned above, in the roof 10 according to the invention the plates of the upper course 24n + 1 are superimposed on the plates of the lower course 24n for less than half the length of the latter in the direction p of the slope of the roof 10. In the forms of realization of Figures 2 and 8, the plates of the upper course 24n + 1 are superimposed on the plates of the lower course 24n for about a quarter of the length of the latter. The plates of the course 24n + 1 are therefore superimposed only on the plates of the course 24n while they do not overlap the plates of the course 24n-1.
    [0058] A further aspect of the invention relates to a method for constructing a roof 10. The method according to the invention comprises the steps of:providing a structure 12 of the roof 10, comprising a plurality of strips;providing a plurality of plates 22;providing a plurality of accessories 30 according to the invention;placing a plurality of slabs 22 to form a lower course 24n;placing a plurality of accessories 30 so that the lower support portion 301 of each accessory 30 rests on a central area of a lower plate 221 of the lower course 24n and on a strip of the structure 12; - placing a plurality of slabs 22 to form an upper course 24n + 1, so that: - the slabs 22 are juxtaposed laterally to each other; - each plate 22 rests on a first upper support portion 302 of a first accessory 30 and on a second upper support portion 304 of a second accessory 30; - the lateral juxtaposition zone 220 between two plates 22 of the upper course 24n + 1 is superimposed on the channel 300 of an accessory 30; and - the plates of the upper course 24n + 1 are superimposed on the plates of the lower course 24n for less than half the length of the latter.
    [0059] As the skilled person may well understand, the method for the construction of a roof 10 according to the invention is defined above in recursive form, and therefore applies to all courses 24 of plates. However, some peculiarities must be kept in mind for the first course 241 and for the last course 24max of plates.
    [0060] In the case of the first course 241 in fact there is not a previous course on the slabs 22 of which to place the accessories 30. In this case it is necessary, for example, to place the accessories 30 on two supports provided by the structure 12, for example two strips or a masonry curb and a lath. Once the accessories 30 have been placed, the method continues by laying the first course 241 of slabs as described above, that is, so that:the plates 22 are laterally juxtaposed to each other;each plate 22 rests on a first upper support portion 302 of a first accessory 30 and on a second upper support portion 304 of a second accessory 30; Andthe lateral juxtaposition zone 220 between two plates 22 of the first course 241 is superimposed on the channel 300 of an accessory 30,
    [0061] In the case of the last 24max course, on the other hand, there is no subsequent course to be supported by means of accessories 30. Therefore, once the last 24max course has been laid, the roof construction method provides, in a per se known way, to install some ridge elements (not shown in the attached figures). The ridge elements, known per se, are suitable for covering the ridge line, where the junction of two opposite pitches of the roof 10 is found.
    [0062] As the skilled person can well understand, the roof 10 according to the invention makes it possible to guarantee the watertightness of the roof 20, both with regard to rising by capillarity, and with regard to infiltration in the lateral juxtaposition area between two neighboring plates of the same course. As can well be appreciated by comparing the roofs 10 schematized in Figures 1 and 7 (relating to the prior art) with those schematized in Figures 2 and 8 (relating to the invention), the latter do not adopt the so-called triple roofing, resulting therefore considerably lighter and cheap.
    [0063] As the skilled person may well understand, the invention allows to overcome the drawbacks highlighted above with reference to the known art.
    [0064] In particular, the present invention makes available a roof 10 and a method for the construction of a roof 10 which, for the same surface to be covered, make it possible to use a smaller quantity of stone with respect to traditional laying.
    [0065] Furthermore, the present invention makes available a roof 10 and a method for constructing a roof 10 which, while using less stone, allow to improve the performance of the roof 10 with respect to traditional solutions.
    [0066] Finally, the present invention makes available a stone roof 10 that is lighter and cheaper than traditional ones.
    [0067] It is clear that the specific characteristics are described in relation to different embodiments of the accessory and of the method with an illustrative and non-limiting intent. Obviously, a person skilled in the art will be able to make further modifications and variations to the present invention, in order to satisfy contingent and specific needs. Such modifications and variants are however contained within the scope of protection of the invention, as defined by the following claims.
