ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
This invention relates to an exterior sheathing element and a method of applying exterior sheathing to a structure. More particularly the invention relates to a sheet metal sheathing element useful for roofing.
BACKGROUND ART OF THE INVENTION
A variety of exterior sheathing elements including those formed from sheet metal are known. Traditionally with exterior sheathing, particularly roofing, the word “tile” is used to indicate a single tile such as a concrete tile. With the development of sheet metal sheathing it has become well established to manufacture elements that visually replicate the designs of such traditional tiles. Because these sheet metal tiles are substantially lighter than their concrete counterparts they are normally manufactured as multiple units, that is, as to replicate say three or four traditional tiles. This capability is one of the advantages these tile have over the traditional “single” tile. This invention is primarily concerned with a multiple sheet metal tile and herein the term “tile” is used accordingly. However, the nature of the invention does lend itself for manufacture and use as a single tile element and the term is to be considered as being applicable to either form of tile.
A first object of this invention is to provide a sheet metal sheathing element particularly useful as a roofing tile that can be manufactured utilising thinner sheet metal than typically used with sheet metal tiles. A second object is to provide a sheet metal tile that replicates a traditional wooden shingle “tile” particularly in a multiple configuration thereof as discussed above relative to concrete tiles. A further object of this invention is to provide such a sheathing element adapted for individual fixing to a supporting structure and subsequent conjoining and fixing of further tiles both laterally and longitudinally of the first tile. The steps can be repeated to cover a desired area of a supporting structure and thus a further object is to provide a method of affixing sheathing tile to a structure. Yet a further object is to provide the public with a further choice in sheathing elements in particular a sheathing element suitable for mounting by relatively unskilled people.
DISCLOSURE OF THE INVENTION
According to a first aspect of this invention there is provided an exterior sheathing element having a first edge portion forming a channel on what, in situ, will be an innerface of the element, and having a second and opposite edge portion forming a channel on what, in situ, will be an outerface of the element, with a part of that second edge portion, being a part set-back from at least one side of the tile, having a mounting tab projecting clear of the second edge portion in a substantially co-planar relationship to a main body of the element, the structure enabling a mounting tab free part at one side of a first sheathing element to be overlapped with a side of a second element with their corresponding folded edge portions engaged, and a first folded edge portion of a third sheathing element to be engaged over and about the second folded edge portion of at least one of the first and second sheathing elements.
According to a second aspect of this invention there is provided a sheet metal exterior sheathing element configured to replicate at least one wooden shingle and comprising a substantially planar body save for strengthening indentations including, adjacent one side, a series of longitudinally extending ribs, the ribs being on that side of a tile intended, in use, to be disposed on the underside when overlapped with a side of a second element to also act as weathering indentations, and having a first edge portion turned back on itself to form a channel on what, in situ, will be an innerface of the element, and having a second and opposite edge portion also turned back on itself to form a channel on what, in situ, will be an outerface of the element with a part of that second edge portion set-back from at least one side thereof having a return fold to extend back on itself and project clear of and substantially co-planar to the body of the element to form a mounting tab, the structure enabling a first and second sheathing element disposed with their sides overlapping and their corresponding folded edge portions engaged, the first folded edge of the lowermost tile being located within the channel of the first folded edge of the uppermost element and the mounting tab free part of the second folded edge of the uppermost element being located within the channel of the lowermost element and a first folded edge portion of a third tile to be engaged over and about the second folded edge portion of at least one of the first and second tiles.
According to a third aspect of this invention there is provided an exterior sheathing element having a substantially planar body and having a first edge portion folded over to overlay, in adjacent spaced relationship to thereby form a first transversely disposed channel, what in situ will be a lower section of an innerface of the element, and having a second edge portion opposite the first edge portion, folded over to overlay, in adjacent spaced relationship to thereby form a second transversely disposed channel, what in situ will be an upper section of an outerface of the element, at least a part of the second edge portion being further folded back on and over itself to form a mounting tab projecting clear of the second edge portion in a substantially co-planar relationship to the plane of the body of the element, the structure of the element enabling a first side portion of a first sheathing element to be overlapped with a second and opposite side portion of a second element without engagement except for the overlapping sections of the first and second folded edge portions, engagement of those sections being by the side section of the first folded edge portion of the underlay element being located in the groove formed by the corresponding section of the overlay element, and the side section of the second folded section of the overlay element being located in the groove formed by the corresponding section of the underlay element, and a first folded edge portion of a third sheathing element to be engaged over the overlapping sections and adjacent sections of the second folded edge portions of the first and second sheathing elements with those second folded edge sections being located in the groove formed by the first folded edge portion of the third element.
According to a fourth aspect of this invention there is provided a method of exterior sheathing a structure with a plurality of sheathing elements as described in any one of the three immediately preceding paragraphs comprising substantially of repeating the steps of positioning a first sheathing element on a sheathing element support of the structure, positioning a second sheathing element with a side section thereof in an overlapping relationship with a section side of the first element and in so doing ensuring their corresponding folded edge portions engage one within the other by the side section of the first folded edge portion of the underlay element being located in the groove formed by the corresponding section of the overlay element, and the side section of the second folded section of the overlay element being located in the groove formed by the corresponding section of the underlay element, and positioning a first folded edge portion of a third sheathing element in engagement over the overlapping sections and adjacent sections of the second folded edge portions of the first and second sheathing elements with those second folded edge sections being located in the groove formed by the first folded edge portion of the third element, and throughout utilising mounting means with the mounting tabs to affix the sheathing elements to the support.
