Definitions

  • This invention relates to a cladding element which is suitable for use in cladding the roof or walls of a building.
  • the cladding element has been developed as a roofing element, and is hereinafter described in such context, but it is to be understood that the element may also be used for cladding the walls of a building structure.
  • the cladding element would normally be formed as a pressed sheet metal element and a plurality of the elements would normally be affixed to structural support members in overlapped relationship to thereby cover an area substantially greater than the surface area of a single element.
  • cladding elements including terra-cotta tiles, concrete tiles, pressed or roll-formed metal panels, timber tile elements (shingles), glassfibre reinforced plastic material panels and various composite material panels.
  • a roofing system can be subjected to further dead loads (imposed, for example, by snow), to wind loading and to other dynamic loadings imposed by, for example, seismic disturbances.
  • dead loads imposed, for example, by snow
  • wind loading imposed, for example, by wind loading
  • other dynamic loadings imposed by, for example, seismic disturbances.
  • These various types of load cause stresses to be induced in the structural members and/or in the cladding elements, and the elements may then break free from the structural members.
  • supplementary load bearing support members in the form of roofing battens and/or timber panels are customarily affixed to the skeletal structural members of a roof, and the cladding elements are affixed to the battens.
  • the cladding element of the present invention has been developed to provide an intrinsic, omnidirectional load bearing capability so that it might be affixed directly to roof rafters, trusses and/or stringers and, thus, so as to avoid the cost of providing and fixing the conventional roofing battens.
  • the cladding element may also avoid the need for some of the customary roof frame bracings.
  • WO­A­8 103 196 discloses a roofing sheet which, as in the case of the present invention, is intended to obviate the need for roofing battens.
  • the referenced specification is directed to a cladding sheet which has a Z-shaped beam at one end and a panel portion which is formed with scalloped flutes which extend into a web portion of the Z-shaped beam.
  • the present invention is directed to a sheet metal cladding element which comprises a panel portion having opposed side edges and opposed top and bottom edges extending in a lateral direction between the side edges.
  • a ridge extends along the top edge of the panel portion and is formed integrally with the panel portion, the ridge including an inner wall which forms an upwardly projecting extension of the panel portion.
  • a plurality of upwardly projecting inverted channel-shaped ribs are formed in the panel portion and extend from the inner wall of the ridge in a direction toward the bottom edge of the panel portion.
  • a downwardly projecting lip is formed at and extends along the bottom edge of the panel portion.
  • the cladding element is characterised in that the ridge is shaped as an inverted channel having substantially parallel inner and outer side walls, in that a series of recesses are formed in the inner wall of the ridge, with each recess being in alignment with one of the ribs and defining a cavity into which the associated rib extends, and in that the lower edge of the panel portion, including the lip, is scalloped inwardly in alignment with and for substantially the full width of each of the ribs.
  • Each element preferably includes at least three ribs and most preferably has about twelve ribs.
  • the cladding element is intended in use to span and be secured to at leasttwo structural members of a building.
  • the ridge portion then performs a bracing function somewhat analogous to the conventional roofing battens, and the panel portion, whilst providing a load bearing structure, functions to provide the weather sealing features which are exhibited by other types of roof cladding.
  • Adjacent (side-by-side) elements are affixed in overlapping relationship, with one rib of one element being nested below a rib of an adjacent (overlapping) element.
  • longitudinally arrayed elements are arranged in overlapping relationship, with the lip at the bottom edge of one element extending over the ridge of a lower element.
  • the cladding element 10 comprises a rectangular panel portion 11 having side edges 12, a top edge 13 and a bottom edge 14.
  • An inverted channel-shaped ridge 15 extends along the top edge of the panel portion 11 and is formed integrally therewith.
  • the complete cladding element is pressed from sheet metal and, whilst shown in Figure 1 as having only three ribs 16 and two gulleys 17, the element would normally be sized to include approximately twelve ribs and eleven gulleys.
  • the element may be made in various sizes, to suit the rafter spacing required by different building codes, but it might typically be 1.8 metres long, between the side edges 12, and 0.4 metres deep between the top and bottom edges 13 and 14 of the panel portion.
  • the ribs 16 have a width which is approximately equal to two-thirds of the spacing between the ribs.
  • the cladding element may be considered as having a base plane which contains the lower surface or wall of the gulleys 17. Side projections 18 and an outward projection 19 of the ridge channel 15 also lie in the same base plane.
  • the ribs 16 are formed with side walls 20 which project upwardly from the base plane (i.e., from the lowerwall of the gulleys 17) and the top surface of each rib is disposed approximately parallel to the gu Iley wall 17.
  • the panel portion 11 has a generally corrugated configuration and the underside of the panel has a shape which complements the top surface which is shown in Figure 1.
  • the ribs and gulleys 16 and 17, whilst shown to have flat surfaces, may be formed to provide the panel with a more curvaceous (undulating) configuration.
  • the bottom edge 14 of the panel portion 11 is formed with a downwardly projecting lip 21.
  • the lip 21 extends for the full width of the element and scallops inwardly at the terminal end of each of the ribs 16. Also, as is best seen from Figures 2 and 3 of the drawings, the lip 21 is inclined to lie parallel to an inner wall 22 of the ridge channel 15.
  • the inner wall 22 of the ridge channel projects upwardly at an obtuse angle to the base plane or gulleys 17 of the panel, and the inner wall then joins the top wall 23 of the ridge which lies parallel to the base plane 17.
  • the outer wall 24 of the ridge channel joins the top wall 23 to the outwardly projecting flange 19, and the outer wall 24 is disposed at 90° to the base plane 17 of the panel.
  • Upwardly extending recesses 25 are formed in the inner wall 22 of the ridge channel, the respective recesses being in alignment with the ribs 16.
  • Complementary, but smaller, projections 26 are formed in the outer wall of the ridge channel opposite each of the recesses 25.
  • two such elements may be mounted side-by-side in overlapping relationship as shown in Figure 4.
  • the right hand rib 16 of one element is positioned to overlie the left hand rib 16 of an adjacent element, and the two elements are interconnected by driving a self-tapping screw 27 through the lapped lips 21 of both elements.
  • screws 28 or other suitable fastening devices are employed to connect the outwardly projecting flange 19 of each channel element to each rafter 29 which is spanned by the cladding elements.
  • adjacent (upper and lower) cladding elements are overlapped in the longitudinal direction of the rafters 29.
  • the lip 21 of an upper element is positioned to overlie the ridge 15 of a lower element, and a self-tapping screw 30 is driven through the two elements.
  • the cladding elements 10 are positively connected to one another and to the rafters 29.
  • Figure 6 of the drawings shows an oblique plan view of a portion of a roof structure (including rafters 29 and a facia board 31) and, in particular, the Figure shows a complete cladding element 10, and two partial such elements, spanning three rafters 29.
  • thefirst row When laying the cladding elements,thefirst row . is positioned above the facia board 31 and the cladding elements 10 of such row are secured to the facia board by fasteners 32. Thereafter, successive rows of the cladding elements are overlapped in the manner shown in Figure 5 until the ridge of the roof is reached.
  • the final row of the cladding elements is secured in the manner indicated in Figure 7A. That is, the projecting flange 19 of each element is secured to the rafters 29 adjacent the ridge board 33 by fasteners 28. Then, a pressed metal ridge cap 34 is fitted over the ridge board and secured to the upper edges of the cladding elements.
  • the (new) side edge of the cladding element is turned up to provide a weather barrier 39, and a hip cap 40 is fitted.
  • a valley channel 41 is positioned between the (new) marginal edges of the cladding elements.
  • the channel is located above the valley rafter 42 and is affixed to stringers 43 which are let into the associated valley creeper rafters 29.
  • a strip 44 of an expandable plastics material is laid along the stringers 43 to bar access to the underside of the cladding elements from the valley channel 41.
