Description of Preferred Embodiment of Invention
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.
CA 02423734 2003-03-26
WO 02/27109 PCT/AU01/01119

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.
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.
As is best seen in FIGS 6 and 7 ribs l6,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.
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
CA 02423734 2003-03-26
WO 02/27109 PCT/AU01/01119

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.
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.
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.
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.
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.
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
CA 02423734 2003-03-26
WO 02/27109 PCT/AU01/01119
9
rebate to retain the panel 10, the arrangement being such that cover strip 15
finishes flush with the face of panel 10.
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.
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.
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.
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 framel 1; supporting a walling
CA 02423734 2003-03-26
WO 02/27109 PCT/AU01/01119
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.
5 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
10 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.
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.
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
CA 02423734 2003-03-26
WO 02/27109 PCT/AU01/01119
11
being formed by affixing a longitudinally extending strip 19 to the panel
proximate an edge thereof. Flange 17 is then engaged in recess 18.
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.
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.
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:-
The aesthetic flexibility possible by use of the coloured cover strip.
Removal of sealing gaskets from direct UV light (possible by use of the
real sealing arrangement) significantly extends the gasket effective life.
. 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.
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.
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.
