  • the length of the building element may vary and may be designed to fit any particular roof structure so as to design one long building element for the entire length of the building or so as to design several smaller building elements and interconnecting these smaller building elements. The advantage of having one long building element for the entire length of the building is obviously that the installation may be performed during one working operation. However, utilising smaller building elements provides an easy to handle and install working operation.
  • the building element may further comprise a bird barrier integrally connected to the building element and extending from the building element in a direction perpendicular to the longitudinal direction and substantially transverse to the first and second direction toward the outer roof covering.
  • the bird barrier may have insect grating preventing insects and birds from entering the pitched roof structure and in particular preventing insects and birds from entering an inner space defined between said outer roof covering and said underroof layer.

  • the second airing element may be constituted by an eaves panel having air ducts and thus may provide a complementary finish to the roof structure.
  • the main purpose of the second airing element is to provide extra support for the gutter member so as to establish a rigid arrangement capable of withstanding heavy loads.
  • the splashing guard section of the gutter member may define a cross sectional profile being shaped as a L, a P, an O, a C, being shaped like a hook or having a semi-circular, circular, semi-elliptic, elliptic, triangular or rectangular cross sectional profile or any combinations thereof.
  • the various profiles of the splashing guard section ensure at least two objectives. One objective is to prevent splashing of drain water out of the gutter member thus providing a splash free zone directly below the gutter member.
  • a second objective is to further increase rigidity of the gutter member by shaping the upper part of the gutter member namely the splashing guard section so that upper part folds down either into the gutter section or on to or along the outside of the gutter section.
  • a further objective is to improve the artistic design of the gutter member.
  • the first and the second airing element respectively may define an inner space or inner spaces having cross sectional profiles shaped semi-circularly, circularly, semi-elliptically, elliptically, triangularly, rectangularly or shaped in any combinations thereof.

  • the outer roof covering may be tiles, slates, metal plates e.g. steel or aluminium plates, ceramic plates, wooden shingles or a thatched roof. The tiles may due to rough surfaces induce holes or scratches in the underroof layer, thus weakening the sealing of the roof structure.
  • elevating the tiles away from the underroof will ensure that the underroof is protected and in some cases provide air ventilation between the underroof layer and the outer roof covering.
  • the air ventilation may be achieved by introducing transverse air ducts in the elevated support or by utilising the outer roof covering's profile, which in some cases provides for a gap between the elevated support and the outer roof covering.

  • the third hollow airing element 118 engages with the first hollow airing element 114 and with an upper part of an eaves guard section 120. This increases significantly the rigidity of the entire building element 112 without significantly increasing the weight of the building element 112.
  • FIG. 5d shows a cross sectional view of a building element according to a fourth embodiment of the present invention, which building element is designated in its entirety by numeral 122.
  • the building element 122 comprises a first hollow airing element 124, a second hollow airing element 126 and a third hollow airing element 128.
  • the third hollow airing element 128 engages with the first hollow airing element 124 and constitutes the upper part of an eaves guard section 130.
  • the second hollow airing element 126 engages with the third airing element 128 so as to increase the rigidity of the upper part of the eaves guard section 130.
  • the building element 122 further comprises an elevated support 132 providing support for the outer roof covering.
  • the elevated support 132 is integrally connected to the building element 122 and protrudes upward from a supporting element 134 described with reference to figure 3 as numeral 78.
  • the elevated support 132 is shown in figure 5d as being hollow and may define any cross sectional shape as well as being solid and define any cross sectional shape.
  • the outer roof covering may be tiles, slates, metal plates e.g. steel or aluminium plates, ceramic plates, wooden shingles or a thatched roof, which all may due to rough surfaces induce holes or scratches in an underroof layer and thus weakening the sealing of the roof structure. Hence, elevating the tiles away from the underroof will ensure that the underroof is protected.
  • the elevated support 132 comprises transverse air ducts for supplying exterior air to a space defined between the outer roof covering and the underroof layer.
  • the transverse air ducts in the elevated support 132 constitute the first airing element thus in this alternative embodiment no transverse air ducts are provided for on the lower side of the building element in the elements designated by numeral 124 and 126.
  • this alternative embodiment is particularly utilised for non-ventilated roof structures having an underroof layer with a water impermeable and water vapour permeable barrier layer.
  • Figures 5a to 5d show a variety of different implementation types of splashing guard sections.
  • Figure 5a shows a splashing guard section 100 shaped as an "O”
  • figure 5b shows a splashing guard section 105 shaped as a mirrored “C”
  • figure 5c shows a splashing guard section 113 shaped as a hook
  • figure 5d shows a splashing guard section 123 shaped as a semi-fold.
  • the various shapes of the splashing guard sections 100, 105, 113 and 123 generally improve the overall rigidity of the gutter member of the building elements 90, 104, 112 and 122 so as to increase the strength of the building element 90.
  • any of the splashing guard sections 100, 105, 113 and 123 may be combined with any building element according to the present invention.
  • the combinations shown in figures 5a to 5c should only be construed as examples and should not be construed as limitations to the scope of the present invention.
  • Figures 5a to 5d show a variety of different implementations of building elements 90, 104, 112 and 122, which in alternative embodiments may include one or more integrated link connections shown in figure 5d as numerals 136, 138.
  • the first integrated link connection 136 enables the supporting element 134 to be rotated so as to match the angle of any particular angle of the outer surface of a rafter.
  • the second integrated link connection 138 may be implemented in any of the building elements 90, 104, 112 and 122 thus improving the adaptability of the building elements 90, 104, 112 and 122 to any particular roof structure.
  • the integrated link connections 136 and 138 provide for easy storage and improved manoeuvrability during mounting of the building element 122.
  • the building elements according to first through sixth embodiment of the present invention may further implemented in corrugated metal so as to increase the mechanical strength.
