Description
- The present invention relates to cladding elements, more particularly to cladding elements adapted for side by side assembly with a like element.
- The invention has been primarily developed in relation to cladding elements which can be connected together along their longitudinal edges to provide roofing/ceiling sheets. However, it will be appreciated by persons skilled in the art that the invention is not limited to this particular use and also finds application in walling, decking and other types of cladding.
- Australian patent no. 711048 discloses a cladding sheet marketed by BHP Steel Pty Ltd under the Trade Mark FLATDEK. FLATDEK has a substantially flat web with generally triangular male and female formations along opposed longitudinal edges. The primarily usage of FLATDEK is of a roofing sheet with the web fastened to a supporting structure, such as battens or purlins by nails or screws which pierce the sheets and engage the support structure. The sheets are installed by pivoting the female formation of the sheet being installed over, and into engagement with, the male formation of the last installed sheet.
- A disadvantage of FLATDEK is the sheets can only be connected by pivoting the female formation over the male formation. This means that, when installing from within a room, FLATDEK can only be installed as ceiling sheets with the male and female formations projecting into the room space, which is visually undesirable. Accordingly, FLATDEK is normally only used a roof sheet.
- Another disadvantage of FLATDEK is the fasteners used to attach it to the support structure are visible. This is also visually undesirable.
- The disadvantages described above in relation to FLATDEK are shared by the majority of the cladding sheets presently available.
- It is an object of the present invention to substantially overcome, or at least ameliorate, one or more of the disadvantages.
- Accordingly, in a first aspect, the present invention provides a cladding element for use in a cladding element assembly, the cladding element including:
- a substantially flat web having a pair of opposed longitudinal edges;
- a male rib formation extending at least partially along one longitudinal edge and having a pair of spaced apart inner and outer upstanding ribs and an engaging formation; and
- a female rib formation extending at least partially along the other longitudinal edge and having an inner upstanding rib, an outer depending rib and a joining section, between the inner and outer ribs and displaced from the plane of the web, and a corresponding engaging formation, at least one of the male or female rib formations being at least partially resiliently flexible,
- wherein the element is adapted for assembly with a like element by positioning of the male formation substantially within the female formation with their respective engaging formations in engagement, whereby the assembled male and female formations together form a substantially rectangular closed channel adapted for concealment of fixing means used to fix the cladding elements to a supporting structure.
- When the major visible surface of the web is the side remote from the male and female formations, the fixing means are positioned between the inner and outer ribs of the male formation. When the major visible surface of the web is the side adjacent to the male and female formations, the fixing means are positioned in the joining section (ie. between the inner and outer ribs of the female formation).
- In one form, the engaging formation of the male rib formation is a flange angled inwardly and towards the web on the distal end of the inner male rib formation and the corresponding engaging formation of the female rib formation is a flange angled inwardly and away from the web on the distal end of the outer female rib formation. At least one of the inner male rib or the outer female rib are preferably flexible to allow resilient flexing displacement as the angled flanges ride over one another during engagement.
- The male and female rib formations are preferably both resiliently flexible.
- In another form, the engaging formation of the male rib formation is an outwardly directed flange on the distal end of the outer male rib formation and the corresponding engaging formation of the female rib formation is an outwardly directed recess on the distal end of the inner female rib formation.
- The cladding element preferably include both forms of the engaging formations defined above.
- Preferably, the proximal end of the outer male rib formation includes an outwardly convex formation adapted to engage with an inwardly concave formation on the proximal end of the outer male rib formation.
- The cladding element is preferably formed from a single piece of roll formed steel.
- The male rib formation is preferably formed by folding some of the web back on itself. A layer of adhesive is preferably included between at least some of the web that is folded back on itself.
- In one embodiment, the layer of adhesive is an adhesive strip, most preferably VHB™ tape marketed by the 3M company. In another embodiment, the layer of adhesive is a glue, most preferably Jetweld TS230™.
- The web preferably includes a plurality, most preferably two, longitudinal stiffening channels. The channels are preferably convex towards the rib formations.
- In a second aspect, the present invention provides a cladding element for use in a cladding element assembly, the cladding element including:
- a substantially flat web;
- a longitudinal interlocking formation formed by folding at least some of the web back onto itself; and
- a layer of adhesive between at least some of the adjacent web folded back on itself.
- In one embodiment, the layer of adhesive is an adhesive strip, most preferably VHB™ tape marketed by the 3M company. In another embodiment, the layer of adhesive is a glue, most preferably Jetweld TS230™.
- Preferred embodiments of the present invention will now be described, by way of examples only, with reference to the accompanying drawings in which:
-
FIG. 1 is a perspective view of the cladding element according to a first embodiment of the invention; -
FIG. 2 is a front view of the element shown inFIG. 1 during installation as a roofing sheet; -
FIG. 3 is a front view after completion of the installation shown inFIG. 2 ; -
FIG. 4 is a front view of the element sheet shown inFIG. 1 during installation as ceiling sheet; -
FIG. 5 is a front view of the element shown inFIG. 4 after installation; -
FIG. 6 is a roll forming flower diagram of the sheet shown inFIG. 1 ; and -
FIG. 7 is a partial front view of the cladding element according to a second embodiment of the invention. - Referring firstly to
FIG. 1 , there is shown a first embodiment of acladding element 10 according to the invention. Theelement 10 is formed from a strip of 0.42 mm base metal thickness (BMT) sheet steel. Theelement 10 is preferably produced by role forming, as will be described in more detail with reference toFIG. 6 . - The
element 10 has a substantially flatcentral web 12 with amale rib formation 14 extending along one longitudinal edge and a female rib formation 16 extending along the other longitudinal edge. When theelement 10 is used as a roofing or ceiling sheet, theweb side 12′ is the lower most part (ie. the underside). When theelement 10 is used as a wall cladding sheet, theweb side 12′ is that which is visible from within the clad room. - The
web 12 also has a pair of longitudinally extending, substantially parallel, spaced apart minorstiffening ribs 18, which are convex in the same direction as the male andfemale rib formations 14, 16. - The web is approximately 260 mm wide with the
stiffening ribs 18 being approximately 12 mm wide and extending away from the plane of the rib by about 5 mm. Themale rib formation 14 is approximately 26 mm wide and extends away from plane of theweb 12 by about 44 mm. The female rib formation is approximately 37 mm wide and extends away from plane of theweb 12 by about 45 mm. Theelements 10 are generally produced in lengths of about 6 meters, with lengths of up to about 9.6 meters possible (generally subject to transporting limitations). - The
male rib formation 14 comprises an innerupstanding rib 20 having anangled flange 22 on its distal end. Theflange 22 is angled inwardly and towards theweb 12. Themale rib formation 14 also includes an outerupstanding rib 24 that has an outwardly directedflange 26 at its distal end and an outwardlyconvex channel 28 at its proximal end. Themale formation 14, with the exception of theinner rib 20, is of double thickness to that of theweb 12 and is formed by folding the web over and back on to itself, as will become more evident fromFIG. 6 . This folding advantageously allows theelement 10 to be formed from a single piece of steel. - The female rib formation 16 has an inner
upstanding rib 30 with an outwardlyconcave recess 32 at its distal end and an outwardlyconcave channel 34 at its proximal end. A joiningsection 36 extends outwardly from the distal end of theinner rib 30 and is substantially parallel to and displaced from theweb 12. Anouter rib 38 depends from the joiningsection 36 and has an angled flanged 40 at its distal end. Theflange 40 is angled inwardly and away from theweb 12. - In the preferred embodiment shown, the thin sheet metal construction of the
element 10 results in various components of the male andfemale rib formations 14, 16 being resiliently flexible under load and able to be displaced from the positions and orientations shown inFIG. 1 and resiliently returned to those orientations when no longer subject to load. -
FIG. 2 shows thecladding element 10, and alike cladding element 10′, during installation as a roofing sheet and being fastened to a supportingbatten 42. The installation process begins with thecladding element 10 being fastened adjacent themale rib formation 14 by a fastener, such as a self tapping/drilling screw 44. Thescrew 44 is driven threw theelement 10 between the inner andouter ribs male rib formation 14. The female rib portion 16 of thecladding element 10′ is pressed over themale rib formation 14 of thecladding element 10 and into locking engagement with same. During this engaging process, therib 38 flexes outwardly as indicated byarrow 46 and therib 20 flexes inwardly as indicated generally by thearrow 48 until theangled flange 22 is received into engagement with theangled flange 40 as shown inFIG. 3 . When this occurs theflange 26 is also located within therecess 32 and thechannel 28 located within thechannel 34. There may also be some flexing of therib formation arrows element 10′ away from theelement 10 to initially position theflange 22 in engagement with theflange 40 and then pivoting the remainder of the male andfemale rib formations 14 and 16 into engagement with one another, as indicated generally by thearrow 54. - Successive elements can thus be sequentially attached to another by following a similar method. The right hand end of the
element 10 is preferably fixed to the batten 42 by initially fastening a section ofcladding element 10 that comprises only the male rib formation 14 (not shown) and engaging thecladding element 10 with thatformation 14 in the manner previously described. - With reference to
FIG. 3 , it can be seen that the male andfemale rib formations 14, 16 form, after assembly, a substantially rectangularclosed channel 56 which advantageously conceals thescrew 44. This advantageously obviates the need for any additional concealed fixing devices or clips, as are required for known cladding sheets. Further, the sheet material adjacent therecesses concave recess 58 in the bottom left hand corner of thechannel 56, which substantially replicates the stiffeningchannels 18 and thus provides a uniform surface appearance to thecladding elements arrow 60. - The installation of the
cladding element 10 as a ceiling sheet will now be described with references toFIGS. 4 and 5 with like reference numerals used to indicate like features in FIGS. 1 to 3. - Turning firstly to
FIG. 4 , theelement 10 is initially fastened to the batten 42 by passing thescrew 44 through the connectingsection 36 of the female rib formation 16. Thecladding element 10′ is then introduced into the position generally shown inFIG. 4 and manoeuvred, in the direction of arrow 62, into engagement with the female rib formation 16 of theelement 10 as indicated inFIG. 5 . During the engaging process theribs arrows rib 24 as generally indicated byarrow 50. Therib 30 will generally not flex due to it being constrained by the attachment of theelement 10 of thebatten 42. - As with the roofing sheet installation, the male and
female rib formations 14, 16 form, after assembly, the substantially rectangularclosed channel 56 which conceals thescrew 44. Further, and again similar to the roofing sheet installation, the male andfemale rib formations 14, 16 also form a downwardlyconvex channel 58 which replicates those provided by theribs 18 to provide a uniform and attractive ceiling appearance when viewed in the direction ofarrow 60. The left hand end of thecladding element 10 is initially fastened to the batten 42 by engagement with a female rib formation 16 (not shown) previously fastened to thebatten 42. -
FIGS. 4 and 5 also represent the top view of an installation of theelement 10 as a wall cladding with thesurface 12′ of theweb 12 presenting a uniform, visually appearing, surface to the interior of the clad room. - The forming of the
closed channels 50 described above also provides improved resistance to leaking compared to known cladding sheets, which rely on the rubber washers between the exposed fastener heads and the cladding sheets. Further, when a roofing installer is notching a tile flushing for a flush fit with the roofing cladding, the substantiallyrectangular channel 56 is a much easier shape for the notched flushing to conform to. This results in reduced installation times and less chance of gaps and associated leaks. - As mentioned above, the
element 10 is preferably formed form a single piece of metal by roll forming in accordance with the process shown in the roll forming flower diagram ofFIG. 6 . - Referring now to
FIG. 7 , there is shown a second embodiment of acladding element 70 according to the invention. Like reference numerals to those used in describing the first embodiment have been used to indicate like features in the second embodiment. - The
element 70 is also formed from a strip of 0.42 mm base metal thickness (BMT) sheet steel and produced by the role forming process described with reference toFIG. 6 . The roll forming process includes folding theweb 12 back onto itself to form themale rib formation 14. This also results in there being two adjacent web layers 72 and 74, between the inner and outerupstanding ribs - In the
element 70, a 6 mm wide strip of adhesive 76 (darkened region) is inserted between thelayers - As stated above, the
adhesive strip 76 prevents the twoweb layers element 70 to be installed between fixings when compared to theelement 10. Alternatively, theelement 70 can withstand higher wind loads than theelement 10, when installed with similar fixing spacing. - Although the invention has been described with reference to a preferred embodiment, it would be appreciated by those skilled in the art that the invention may be embodied in many other forms. For example, although it is preferred, it is not necessary for the male and female rib formation to extend over the entire length of the cladding elements. An alternative is a series of discrete spaced apart lengths of male and female rib formations. Further, the element can alternatively be formed from sheets of plastics or other materials.
