Definitions

  • the present invention relates to a rooftop covering structure for self-ventilated roofs.
  • the present invention relates to a rooftop covering structure for self-ventilated roofs with slanted pitches; use to which the following discussion will make explicit reference without implying any loss of generality.
  • Each pitch of the roof is usually formed by support beams that rest on the supporting structures of the building; boarding placed to cover the support beams; and a series of imbrices, tegulae or roofing tiles in impermeable material that completely cover the boarding so as to form an impermeable covering that allows rainwater to flow freely on the upper face of the pitch to the eaves of the roof, without reaching the underlying boarding and beams.
  • the support beams, the boarding and/or the impermeable coverings are structured in such a way so as to form a series of cavities or ventilation ducts that extend within the pitch, from the eave lines to the rooftop of the roof, and are open at both ends so as to allow air to penetrate below the impermeable coverings at the side edge of the pitch which forms the eave line, returning along the slanted pitch up to the rooftop line, and finally exiting from the lateral edge of the pitch forming the rooftop of the roof.
  • the self-ventilated roofs with slanted pitches are also provided with an additional covering structure, which is arranged astride the two pitches, at the rooftop line of the roof and for the entire length of the same line, and is structured in such a way to prevent rain water from reaching the side edges of the pitches forming the rooftop, and from there penetrating below the impermeable coverings of the pitches damaging the boarding and support beams; and a row of tegulae or rooftop roofing tiles arranged astride the two roof pitches, covering and protecting the rooftop covering structure .
  • the rooftop covering structure is structured so as to allow free air circulation, and prevent rainwater from reaching the pitches lateral edges forming the rooftop of the roof.
  • Each rectilinear metal section-bar is placed astride the line of junction between the boarding of two slanted pitches of the roof, so as to surface from the longitudinal groove delimited by impermeable coverings of the pitches, and has the two major side edges substantially L folded so that each of said edges can stably rest on the boarding of a respective slanted pitch, below the impermeable coverings of the pitch, and therein be rigidly and immovably anchored.
  • the central band that forms the top of the metal section-bar and the lateral sides of the same section-bar are conveniently perforated in such a way so as to allow the passage of air, while the row of tegulae or rooftop tiles is arranged astride the impermeable coverings of the two roof pitches, covering the crest or top of the metal section-bar with an inverted U- shaped cross section.
  • the above-described rooftop covering structure has shown certain sealing limitations when, in addition to rainfall, strong intensity winds with speeds above 60-80 kilometers per hour are added.
  • the water droplets nebulize due to the impact on the impermeable coverings of the pitch, and the wind can push the nebulized water inside the rectilinear metal section-bar with a substantially inverted U- or ⁇ -shaped (omega) cross-section where the water condenses back into liquid form and can reach and irreparably damage the boarding.
  • a rooftop covering structure for self-ventilated roofs as specified in Claim 1 and preferably, though not necessarily, in any one of the dependant claims.

  • FIG. 2 is a partially exploded perspective view of the rooftop covering structure shown in Figure 1; whereas
  • FIG. 3 is a front view of the rooftop covering structure shown in Figure 2.
  • referral number 1 indicates as a whole a rooftop covering structure which is specifically made to cover the rooftop of a self-ventilated roof 2 composed of at least two slanted pitched 3 that are juxtaposed so as to form/define a longitudinal groove 4 that extends along a preferably, though not necessarily horizontal directrix, at the maximum height from the ground, and is usually called rooftop 4 or rooftop line.
  • the side edges (not shown) of slanted pitches 3 which, on opposite bands of the rooftop 4, are at the minimum height from the ground are instead called eave lines of the roof.
  • each slanted pitch 3 of the roof is preferably, though not necessarily, formed by support beams 5 resting on the support structures of the building (not shown) ; and by two intermediate boarding 6 that are placed to cover the beams 5, one above the other with the interposition of appropriate spacers, so as to form a series of crossed cavities or ventilation ducts that extend within the pitch, from the eave lines to the rooftop 4; and by a series of imbrices, tegulae or roofing tiles 7 in impermeable materials that completely cover the boarding so as to form a coat of impermeable covering 7, which allows rainwater to flow freely on the upper surface of the slanted pitch 3 towards the eave lines of the roof, without reaching the boarding 6 and the beams 5 below.
  • the series of cavities or ventilation ducts 6a delimited by the two boardings 6 are open at both ends so as to allow an air-flow f to penetrate below the impermeable coverings 7 of the rooftop corresponding to the side edge (not shown) of the slanted pitch 3 that forms the eave line, returning along the slanted pitch 3 to the rooftop line, and finally exiting from the lateral edge of the rooftop that defines the longitudinal groove or rooftop 4.
  • the rooftop covering structure 1 is positioned astride the two slanted pitches 3, within the longitudinal groove 4 which defines the rooftop line, so as to engage said longitudinal groove 4 for its entire length, and is structured in such a way so as to prevent rainwater from reaching the lateral edge of the slanted pitch 3 that borders the rooftop 4, and from there flowing below the impermeable coverings 7 damaging the boarding 6 and the support beams 5.

  • the two longitudinal flat shelves 10 serve to prevent the rain from falling directly onto the lateral sides 9b of the rectilinear section-bar 9, and then infiltrate within the section-bar; and the tegulae or rooftop tiles 8 are arranged on either side of the rectilinear section-bar 9, preferably but not necessarily, resting on two longitudinal flat shelves 10.
  • each lateral side 9b of the rectilinear section-bar 9 presents, along the longitudinal plane which is laterally bound by the longitudinal flat shelf 10 and by the side edge 9a where the boarding 6 rests, a series of through-slots 11 of a preferably, though not necessarily, oblong shape, which are aligned one after the other so as to form a number of longitudinal rows which are parallel and side by side to one another and preferably, though not necessarily, also parallel to the underneath part of the major side edge 9a of the section-bar.

  • the protective hoods 12 have preferably, though not necessarily, a substantially semicylindrical shell- shaped profile, and are preferably, though not necessarily, made of one piece with the rest of the body of the rectilinear section-bar 9.

  • the central band 9c of the rectilinear section-bar 9 which forms the crest of the section-bar and is bound by the two longitudinal flat shelves 10, is instead provided with a large quantity of ventilating through-holes of a shape preferably, though not necessarily, circular, which are substantially evenly distributed upon the surface of the section-bar, and have a nominal passage section lesser than that of the slots 11.

  • the hooking fins 14 may be made in one piece with the respective flat sheets 13.
  • the flat sheets 13 forming the rectilinear section-bar 9 are made of metal or plastic material, via a cold-pressing process (in the they are made of metal material) or injection moulding (in the case they are made of plastic material), so as to achieve the various hoods or protective caps 12 and protruding hooking fins 14 together with the rest of the sheet 13.
  • the longitudinal flat shelves 10 can be made of metal or plastic material, preferably but not necessarily, by a cold-pressing or injection moulding process.
  • the operation of the rooftop covering structure 1 is readily apparent from that described above, and therefore does not require further explanation. If not to specify that the projecting protective hoods or caps 12 arranged to cover the slots 11, prevent the entry of nebulized water inside the rectilinear section-bar 9 in the presence of winds with speeds exceeding 100 miles per hour, without hindering the free circulation of air. The advantages deriving from the particular structure of the rectilinear section-bar 9 are significant.
