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, 11a 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 successfully 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.
  • US 4 177 615 describes a composite panel and fixing clip where adjacent panels are joined by a "standing seam” type joint.
  • An upper portion of the fixing clip is incorporated into the standing seam joint.
  • the fixing clip is in two parts.
  • An upper part includes the above-mentioned upper portion and a lower plate portion which rests on a part of the insulating material and, at its edge, on a lip formed by deformation of the lower sheet member of the composite panel.
  • a lower part of the clip includes a plate portion which rests in use on the plate portion of the upper part of the clip and a flange which depends downwardly from the plate portion and penetrates the insulating material to contact the lower sheet member of the panel.
  • US 4 177 615 does not provide a complete solution. It is disadvantageous for the clip to penetrate the insulating material as this makes accurate positioning of the clip more difficult and is damaging to the integrity of the insulating material. Also, this design does not overcome the problem of compression of the insulating material by over-tightening of the fixing screw (which acts on the plate portions). In this respect, the fact that the plate portion of the lower part of the clip rests on the lip formed from the lower sheet member is insufficient. A further problem is that the clip does not resist compression of the insulating material caused by foot traffic (which occurs when the panels are being fitted or during maintenance).
  • the plate portion of the upper part of the clip lies below the plate portion of the lower part of the clip and (other than the lip of the lower sheet member, which is not sufficient) there is nothing to present downward movement of the upper part of the clip resulting from the weight of a person standing on the outer surface of the panels. Compression of the insulating material in these ways can result in a loosening of the fixings so that the strength and integrity of the roof structure formed from the composite panels is compromised.
  • 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 clip for securing composite panels comprising inner and outer sheet members and a body of insulating material disposed therebetween to a supporting structure, the clip comprising:
  • first and second wall portions depend from opposite sides of the fastening web.
  • the head portion comprises a hook-like formation which engages corresponding hook-like formations of the adjacent composite panels, the hook-like formation having a leading edge spaced apart from the first upstanding wall portion at a side thereof opposite to the fastening web.
  • the clip comprises first and second fixedly engaged clip parts, the first clip part comprising the head portion, the first upstanding wall portion and a first fastening web portion, the second clip part comprising the second wall portion and a second fastening web portions, said fastening web portions lying one above the other and together forming the fastening web.
  • a layer of thermally insulating material is disposed between the respective first and second fastening web portions.
  • first and second slots are provided in a lower part of the first upstanding wall portion and the second clip part further comprises a third upstanding wall portion disposed adjacent the first upstanding wall portion and including oppositely laterally directed tongues which are deformed into engagement with the respective slots of the first upstanding wall portion, thereby to secure the first and second clip parts together.
  • a composite panel assembly comprising:
  • the head portion of the clip comprises a hook-like structure defining a hollow interior and a head portion of the second engagement formation is inserted in use into said hollow interior.
  • the head portion of the clip is resiliently deformed to a relatively expanded configuration as it engages the head portion of the second engagement formation and returns substantially to its initial configuration when the head portion of the second engagement formation is fully inserted therein.
  • the first engagement formation comprises a head portion comprising a hook-like structure defining a hollow interior and the engaged head portions of the second engagement formation and the clip of an adjacent panel are inserted in use into the hollow interior of said head portion of the first engagement formation.
  • the head portion of the first engagement formation is operatively deformable into engagement with the head portions of the second engagement formation and clip of said adjacent panel.
  • a layer of sealing material is formed along the length of the first and/or second minor faces.
  • a roofing structure comprising:
  • 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.
  • one or both of the minor faces includes a layer of sealing material along its length.
  • the composite panel 50 employed in the invention has an outer sheet member 100 and an inner sheet member 102.
  • 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 is preferably an insulating foam such as a polyurethane or a polyisocyanurate foam which is injected into the void between sheet members 100, 102 during manufacture, to substantially fill the void.
  • 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.
