Definitions

  • the present invention relates to roofing panels and panels for wall cladding or construction made from a metallic substrate, in particular steel or aluminium. Panels of this sort may be used to construct the roof or walls of a new building or to replace the roof or walls of an existing building.
  • FIG. 1 is a lateral cross-section through a roofing structure.
  • brackets or halters 16 are fixed to suitable supporting locations on the underlying structure 20.
  • a liner sheet 21 is placed over the underlying structure 20, and the halters 16 are attached to the underlying structure 20 through the liner sheet 21, by means of suitable fixing means 22, such as self tapping screws.
  • Panels 11, a of sheet material which form the outer surface of the roof are mounted on the halters 16.
  • the halters 16 include an enlarged head portion 18.
  • a first panel 11 has a hook-like formation 12 which is "snapped” into position over the enlarged head portion 18 of the halter 16.
  • the second panel 11a has a hook-like formation 12a which is substantially identical to formation 12, and a second hook-like formation 14a.
  • the panel 11a is mounted by "snapping" the formation 14a over both the halter head portion 18 and the hook-like formation 12 of the panel 11.
  • the panels 11, 11a are then secured to the halter 16 by means of an electrically driven "zipping tool" which passes along the seam (formed by the halter and formations 12 and 14a) tightening the curl of the formation 14a so that it grips the formation 12 and the halter 16 thus locking the three components and forming a tight seal.
  • This sort of product is widely used and accepted for long-life span metal roofing.
  • composite panels which, as manufactured, include a layer of insulation in the void between the panels forming the exterior of the building (e.g. panels 11, 11a) and the internal liner sheet (21).
  • the insulation may be a polyisocyanurate or polyurethane foam.
  • the applicants are not aware of any commercially marketed composite panel which employs a standing seam type joint between adjacent panels.
  • a particular problem in considering such a system arises because of the need for brackets (halters) to pass from the exterior roofing panel through the entire composite panel in order to attach them to the underlying supporting structure.
  • the presence of the halters makes it extremely difficult to maintain the integrity of the insulation.
  • FIG. 1B One prior art method of providing insulating material is illustrated in Figure 1B. It can be seen that this is not a true composite panel. Each layer of the structure must be applied sequentially to the building structure. Thus, liner 21 and vapour barrier 26 are applied first. The halters 16 are then fixed in position and the insulating material 24 is laid in position around the halters. The insulating material is commonly in the form of foam blocks or strips, or a felt or fibrous material. Finally, the outer roofing panels 11, 11a are applied as indicated above. It will be appreciated that roofs constructed in this way can provide a satisfactory finished product, but a large amount of assembly is required on site which is time consuming and which can be difficult, for example in adverse weather conditions.
  • FIG. 2A shows a section through a composite panel and Figure 2B shows the interlocking of two such composite panels.
  • the composite panel 61 has an outer panel member 62 in the form of a web of metallic material such as steel or aluminium which in use will form the outer surface of the roof or wall.
  • a second panel 64 provides the inner surface of the panel 61 and an insulating material such as a foam insulating material 66 is disposed between the panel members 62, 64.
  • Panel member 62 is so shaped as to include an upstanding formation 72 in the form of a post 84 and an enlarged head portion 86.
  • At the other lateral side of the panel member 62 is another upstanding formation 74 in the form of a post 92 and a hook-like formation 90.
  • FIG 2B two panels 61 and 61a are illustrated.
  • the panels are identical and the same reference numbers are used for like components of the panels, except that the suffix "a" has been added to each reference numeral for the left-hand panel, as illustrated.
  • the panel 61 is secured to the underlying structure 110 by fastening means 112 in the form of a self-tapping screw.
  • the panel member includes a flat surface 96 at its margin which is engaged by the head 114 of the fastening means 112.
  • the panels 61, 61a are secured together by snapping hook-like formation 90a over enlarged head portion 86 and tightening the seam in a similar way to that described above in relation to Figure 1A.
  • the panel 61 is provided with a bead of sealing material 78 to form a vapour seal between the interior and exterior of the building.
  • Panel 61a also includes a portion 100c which serves to cover the fastener head 114 to protect it from damage and deterioration caused by exposure to adverse weather conditions.
  • the panel shown in Figures 2A and 2B does have some disadvantages. Firstly, roofing panels and the like are often subjected to changing external temperatures. Depending on the geographic location of the building, the external temperature may vary from a minimum of about -10°C to about 45°C, while the internal temperature of the building remains essentially constant. This means that the panel must accommodate differential thermal expansion and contraction of the inner and outer layers 64, 62. Usually the outer layer 62 moves to a greater extent than the inner layer 64. In the composite panel shown in Figures 2A and 2B, expansion of the outer layer 62 causes rotation of the fastening means 112 about the point at which it enters this underlying structure 110. The thermal expansion and contraction causes considerable movement of the fastener over time, which can lead to the failure of the fastener and elongation of the hole through the inner layer 64, so affecting the moisture barrier properties of inner layer 64.
  • Figures 2A and 2B may be subject to the phenomenon known as "cold bridging" in which the joint 86, 90 between the panels and the fastening means 112 provides a thermally conductive link between the outer layer 62 and the underlying structure 110 of the building which supports the panel. This results in cold “tracking” from the exterior to the interior of the building and causing condensation on the supporting structure (e.g. purlins) 110.
  • cold bridging the joint 86, 90 between the panels and the fastening means 112 provides a thermally conductive link between the outer layer 62 and the underlying structure 110 of the building which supports the panel.
  • EP 0 900 891 describes a roofing system comprising adjacent thermally insulating panels secured to an underlying structure by a screw.
  • the screw may act on an optional Z-shaped profile.
  • US 4 177 615 describes a roofing system of interlocking adjacent panels according to the preamble of claim 1.
  • a two-paet clip arrangement co-operates with a screw to secure the panels to an underlying structure.
  • the present invention seeks to provide an improved composite panel of the standing seam type which attempts to overcome some of the disadvantages of the above described prior art.
  • a composite panel assembly comprising:
  • the first surface portions are generally planar and extend generally perpendicularly with respect to the first sheet member.
  • the second surface portions are also preferably generally planar and extend generally perpendicularly with respect to the second sheet member.
  • the hook-like structure of the head portion of the clip has a leading edge which is spaced apart from the wall portion of the clip and which is so disposed that the leading edge of the clip and the fastening portion of the clip are on opposite sides of the wall portion of the clip.
  • the head portion of the first engagement formation is desirably operatively deformable into engagement with the head portions of the second engagement formation and the clip of said adjacent panel.
  • a bead of sealing material is formed along the length of the first and/or second minor faces.
  • a second aspect of the invention provides a roofing structure comprising a composite panel assembly as claimed in any preceding claim.
  • the roofing structure comprises at least two of the composite panels joined at their marginal edges, the first, second and third surface portions of a first composite panel lying in spaced apart relation to the respective first, second and third surface portions of a second composite panel thereby to define a void between each pair of confronting surface portions of the panels.
  • the confronting first surface portions are spaced apart by a first distance and the confronting third surface portions are spaced apart by a second distance, which second distance is greater than said first distance.
  • first surface portions are generally planar and extend generally perpendicularly with respect to the first sheet member.
  • the second surface portions are generally planar and extend generally perpendicularly with respect to the second sheet member.
  • each of the first and second engagement formations comprises an upstanding wall portion and a head portion, the head portions co-operating in use to join the panels together, and wherein the respective first and second upstanding wall portions of the first and second panels are spaced apart by a distance not greater than or substantially equal to said first distance.
  • the roofing structure of this aspect of the invention further comprises a fastening means having a head portion acting on an upper surface of said planar fastening portion of the clip and a shank portion when penetrates said insulating material and is securable in a underlying supporting structure.
  • a washer of thermally insulating material is disposed between the head portion of the fastening means and the foot portion of the clip.
  • one or both of the minor faces of at least one panel includes a bead of sealing material along its length.

  • Sheet members 100, 102 may include ridges or other corrugations (not shown) for improved strength.
  • the sheet members 100 and 102 are made from a suitable metallic material such as steel or aluminium. Non-metallic materials may also be used to form sheet numbers 100, 102 provided that they have sufficient strength, rigidity and durability.
  • Outer surfaces 101, 103 of the sheet members 100, 102 form the respective major external surfaces of the composite panel 50.

  • the insulating material may itself be adherent, or may be adhered, to the inner surfaces of the sheet members 100, 102.
  • first and second engagement formations 106, 108 are provided which extend substantially along the length of the composite panel 50.
  • these engagement formations 106, 108 are formed integrally with the outer sheet member 100 and comprise respective upstanding wall portions 110, 112 and head portions 114, 116.
  • the head portions 114, 116 are illustrated to have a hook-like shape and such a construction is much preferred, but other constructions can be used, provided that the respective engagement formations 110, 112 co-operate to join adjacent panels together.
  • the composite panel 50 has minor faces 118, 120 extending between the sheet members 100, 102 and substantially defined by side surfaces of the insulating material 104.
