DESCRIPTION OF PREFERRED EMBODIMENT OF INVENTION

[0076] One aspect of the invention is best explained by turning first to FIG. 7 which shows cladding panel walling fixed in place on a building. As seen in FIG. 7, the building assembly of the present invention includes a plurality of elongate jointing elements 12 (of which only one is shown) adapted to be fastened relative to a building frame in the form of top hat section 11 by screws 13. Each jointing element 12 is in the form of a top hat section and includes an outwardly facing channel portion 22 and at least one flange 17 (see FIG. 4 wherein, as is preferable, a pair of flanges 17 are shown) extending laterally from the channel portion 22 for engaging a cladding panel 10. A plurality of cladding panels 10 have elongate recesses 18 formed in their edges (see FIG. 6) for engaging the flanges 17 for supporting the cladding panels 10 to form a wall. Sealing means in the form of an elongated or longitudinally extending gasket 14 is positionable between building frame 11 and elongate jointing elements 12 when fastened thereto for substantially sealing the space between building frame 11 and the cladding panels 10 against the ingress of moisture.

[0077] Gasket 14 is made from a resilient flexible material such as EPDM or neoprene for example and has longitudinally extending parallel ribs 16 which are adapted to resiliently engage the inner surface of cladding panels 10 when flanges 17 engage in recesses 18 in cladding panels 10. Ribs 16 extend outwardly of building frame 11 when gasket 12 is positioned thereagainst by jointing element 12 when fastened to the building frame by screws 13.

[0078] As is best seen in FIGS. 6 and 7 ribs 16 are dimensioned such that engagement of flanges 17 in recesses 18 biases the ribs against the inner surface of cladding panels 10. Thus the outwardly extending height of ribs 16 is slightly greater than the external dimension of the channel portion 22 of jointing elements 12 less the width of the inner portion of walling panel 10 formed by recess 18. This results in the biasing configuration seen in FIG. 7 when the panels are slid over the flanges as seen in the directions of the arrows in FIG. 6.

[0079] In use, as seen progressively in FIGS. 4-7, cladding panels are fastened to building frames in the method of the present invention by positioning sealing means 14 between an elongate jointing element 12 and the building frame 11, fastening the elongate jointing element 12 relative to the building frame, forming an elongate recess 18 in the edge of a cladding panel 10, and engaging flange 17 in recess 18. The jointing element 12 includes an outwardly facing channel portion 22 for fixing jointing element 12 relative to the building frame 11 and flanges 17 extending laterally from the channel portion 22 for engaging cladding panels 10. The sealing means 14 is adapted to substantially seal the space between the building frame 11 and the cladding panels 10 against the ingress of moisture.

[0080] It will thus be appreciated that in one aspect the present invention can be seen as a wall cladding assembly having elongate jointing elements 12 for mounting to a frame 11 and having flanges 17 extending therefrom, sealing means 14 positionable between the frame 11 and an elongate jointing element 12 when fastened thereto for substantially sealing the wall cavity against the ingress of moisture, and a plurality of walling members 20 having elongate recesses 18 along opposed sides thereof for receiving the flanges 17 whereby the plurality of walling members 20 is supported by the plurality of jointing elements 12 to form a wall.

[0081] In use, a wall is assembled in accordance with the method of one aspect of the invention by positioning sealing means 14 between a frame 11 and a plurality of elongate jointing elements 12, the sealing means 14 being adapted to seal the wall cavity against the ingress of moisture and the jointing elements 12 having flanges 17 extending therefrom. The jointing elements 12 are mounted to the frame 11, and a walling member 20 having elongate recesses 18 along opposed sides thereof is supported between a pair of jointing elements 12 by positioning the flanges 17 in the recesses 18.

[0082] Another aspect of the invention is illustrated in FIGS. 1-3 wherein elongate cover means in the form of strips 15 are fastened to the flanges 17 as seen in FIG. 2 for covering the channel portion 22. Strips 15 and flanges 17 when fastened together are receivable within recesses 18. Strips 15 are provided in a range of colours so that a range of aesthetic choices are available to coordinate with a range of panel colourings and tonings.

[0083] It will be appreciated that cover strip 15 may be fastened to flanges 17 before panels 10 are slid over the flanges (as illustrated) or alternatively can be inserted into recesses 18 and fastened to flanges 17 when the panels 10 have already been slid over flanges 17.

[0084] An alternative arrangement to that described above is illustrated in FIG. 3 wherein recess 18 is in the form of a rebate, flange 17 being received in the rebate to retain the panel 10, the arrangement being such that cover strip 15 finishes flush with the face of panel 10.

[0085] Thus it will be appreciated that a building assembly in accordance with this aspect of the invention includes a plurality of elongate jointing elements 12 adapted to be fastened relative to a building frame 11 and each including an outwardly facing channel portion 22 and at least one flange 17 extending laterally from the channel portion 22 for engaging a cladding panel 10. The building assembly also has a plurality of cladding panels 10 having elongate recesses 18 along and proximate the edges thereof for engaging the at least one flange 17 for supporting the cladding panel 10 to form a wall, and elongate cover means 15 fastenable to the at least one flange 17 for covering the channel portion 22.

[0086] In use, cladding panels are fastened to building frames in accordance with the method of this aspect of the invention by fastening an elongate jointing element 12 relative to the building frame 11, the jointing element 12 including an outwardly facing channel portion 22 for fixing the jointing element 12 relative to the building frame 11 and at least one flange 17 extending laterally from the channel portion 22 for engaging a cladding panel 10. An elongate recess 18 is formed along and proximate the edge of a cladding panel 10, the flange 17 is engaged in the recess 18, and elongate cover means 15 are fastened to the at least one flange 17 for covering the channel portion 22.

[0087] It will also be appreciated that a wall cladding assembly in accordance with this aspect of the invention includes elongate jointing elements 12 for mounting to a frame 11 and having flanges 17 extending therefrom, a plurality of walling members 10 having elongate recesses 18 along opposed sides thereof for receiving the flanges 17 whereby the plurality of walling members 10 is supported by the plurality of jointing elements 12 to form a wall, and elongate cover means 15 for fastening to the jointing elements 12 to cover the jointing elements 12 between adjoining walling members 10.

[0088] In use, a wall is assembled in accordance with the method of this aspect of the invention by mounting a plurality of elongate jointing elements 12 having flanges 17 extending therefrom to a frame 11; supporting a walling member 10 having elongate recesses 18 along opposed sides thereof between a pair of jointing elements 12 by positioning the flanges 17 in the recesses 18, and fastening elongate cover means 15 to the jointing elements 12 to cover the jointing elements 12 between adjoining walling members 10.

[0089] Another aspect of the building assembly of the present invention is best seen in FIG. 8 and includes a plurality of elongate jointing elements 12 (of which only one is shown) adapted to be fastened relative to a building frame in the form of top hat section 11 by screws 13. Each jointing element 12 is in the form of a top hat section and includes an outwardly facing channel portion 22 and at least one flange 17 (as is preferable, a pair of flanges 17 are shown) extending laterally from the channel portion 22 for engaging a cladding panel 10. A plurality of cladding panels 10 have recesses 18 formed along and proximate their edges for engaging the flanges 17 for supporting the cladding panels 10 to form a wall. Recesses 18 are formed by affixing a longitudinally extending strip 19 to panel 10 proximate an edge thereof. Strip 19 is preferably an aluminium extrusion bonded to panel 10 and has a longitudinally extending rebated lap 20, the rebate constituting recess 18 when strip 19 is fixed to panel 10.

[0090] A longitudinally extending gasket 21 is fixed to the outer edge of the lap 20 for sealing against the outwardly facing channel portion 22 when flange 17 is received in recess 18. Gasket 21 is preferably made of a closed cell foam. Strip 19 is fixed to panel 10 such that the distance between the outer edge of lap 20 and the edge of panel 10 is slightly less than the combined thickness of the outwardly facing channel portion 22 and gasket 21. Consequently gasket 21 will be compressed to seal against the outwardly facing channel portion 22 when flange 17 is received in recess 18.

[0091] In use, cladding panels 10 are fastened to building frames 11 in the method of this aspect of the present invention by fastening an elongate jointing element 12 relative to the building frame, the jointing element having an outwardly facing channel portion 22 for fixing the jointing element relative to the building frame and at least one flange 17 extending laterally from the channel portion 22 for engaging a cladding panel 10. An elongate recess 18 is formed along and proximate the edge of the cladding panel 10, the recess being formed by affixing a longitudinally extending strip 19 to the panel proximate an edge thereof. Flange 17 is then engaged in recess 18.

[0092] FIGS. 9 to 18 illustrate the use of the various aspects of the present invention in a variety of applications as listed above in the description of the drawings.

[0093] A range of materials can be used for the various components and the scope of protection is not limited in this regard. Thus the panels for example can be made of any suitable cladding material.

[0094] It will be appreciated that the various preferred embodiments of the present invention have a number of advantages over known methods and assemblies of fastening cladding panels to building frames. These include:—

[0095] The aesthetic flexibility possible by use of the coloured cover strip.

[0096] Removal of sealing gaskets from direct UV light (possible by use of the real sealing arrangement) significantly extends the gasket effective life.

[0097] Furthermore suitable gaskets for external mounting as in the prior art are available in a limited colour range and the replacement of the external gasket by a cover strip allows for the space between adjoining panels to be better colour coordinated with panel colours.

[0098] The fixing of relatively thin panels to building frames is facilitated, particularly panels which are sufficiently thin not to allow for grooves to be formed in the edges.

[0099] It will of course be realised that whilst the above has been given by way of an illustrative example of this invention, all such and other modifications and variations hereto, as would be apparent to persons skilled in the art, are deemed to fall within the broad scope and ambit of this invention as is herein set forth.
