DETAILS:

15567/02 FILED ON FEBRUARY 13, 2002 The following Statement is a full description of this invention including the best method of performing it known to me/us: The present invention relates to a wall construction.

In accordance with one aspect of the present invention there is provided a wall construction comprising a plurality of spaced upright stud members and plurality of wall panels mounted on transversely extending pins in the stud members, wherein the pins are encased in a water repellant tube and are arranged to be removed after construction is complete.

The present invention will now be described, by way of example, with reference to the accompanying drawings, in which Figure 1 is a plan view of a wall construction in accordance with one embodiment of the present invention; and Figure 2 is a plan view of a wall construction in accordance with a further embodiment of the present invention.

There is shown in Figure 1 a wall construction 10 comprising a plurality of spaced upright channel-shaped stud members 24 arranged in a row. Further, each channelshaped stud member 24 has an open side 25 facing outwardly.

As shown, the stud members 24 have intumrned flanges 50 adjacent the open sides The flanges 50 extend inwardly from side walls 52 of the stud members 24. The flanges 50 extend along the length of the respective side walls 52 from top to bottom of each stud member 24. As shown the flanges 50 extend partially across the open sides The use of the flanges 50 increases the strength of the construction because concrete contained in the stud member 24 is less easily delaminated under pressure compared to when the flanges 50 are absent.

The wall construction 10 has an exterior formed by concrete panels 30 which have ties 28 projecting from rear faces thereof. The ties 28 are pre-cast in the panels Further, substantially horizontal pins 26 are associated with the channel-shaped studs 24. The pins 26 may extend into the side walls of the channel-shaped stud members 24 so as to be about the same length as the width of a stud member 24. Alternatively, the pins 26 may extend through side walls of the channel-shaped stud members 24 for a longer distance such as from end to end of a wall construction The panels 30 are mounted to the wall construction 10 by engaging downwardly extending ties 28 located adjacent upper ends of the panels 30 with the pins 26.

Concrete panels of the type 30 described herein and wall constructions utilising same are described in more detail in Australian Patent Numbers 243505, 551845 and 641920.

The panels 30 are mounted together in side by side relation to form a complete wall construction 3_ On an inner wall side of each stud member 24 there are attached a plurality of spaced substantially horizontal members 20. Between an inner wall side of each stud member 24 and each substantially horizontal member 20 there is disposed a pad of heat insulating material 32. This pad of heat insulating material 32 may be a heat insulating polymeric plastics material.

On an inner side of the substantially horizontal members 20, a plurality of spaced upright post members 14 are mounted. A layer of reflective foil laminate, such as Sisilation T M paper 16 is attached to inner faces of the post members 14 and extends along the length of the wall construction 10. Another layer of reflective foil laminate 18 is mounted between outer faces of the post members 14 and inner faces of the substantially horizontal members 20 and extends along the length of the wall construction Thus, the layer of reflective foil laminate 18 is placed between the substantially horizontal members 20 and the post members 14. The layer of reflective foil laminate 16 is placed on inner faces of the post members 14. An internal wall cladding 22 is attached to the layer of reflective foil laminate 16.

The construction described creates a water vapour trap in the cavity between the layers 16 and 18 of reflective foil laminate which has the effect of significantly lowering heat transfer coefficient across the wall construction 10 and therefore improving the insulation properties of the wall construction 10. This is because the layer 18 is, in use, relatively cool during cold weather compared to the layer 16. Thus, under these conditions, water vapour in the cavity between the layers 16 and 18 tends to condense and run to the bottom of the cavity.

In Figure 2 there is shown an alternative embodiment of the wall construction 10 of the present invention. In Figure 2 like numerals represent like parts as are found in Figure 1. In the embodiment of Figure 2 a tube 40 is placed around each pin 26 in a tight fit. This embodiment allows for the possibility of the pin 26 being withdrawn from the channel member 24 after construction is complete. Typically, the tube 40 is formed of a water repellant material such as polyvinyl chloride so as to reduce corrosion of the ties 28. This embodiment is also envisaged for use with retaining walls as in which case items 14, 16, 18, 20, 22 and 32 could be dispensed with.

Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of this present invention. The example presented has an outer wall comprised of concrete blocks. The scope of this invention also includes the use of various other walls including but not limited to sandstone, brick veneer, timber, and concrete.

Claims

1. A wall construction comprising a plurality of spaced upright stud members and a plurality of wall panels mounted on transversely extending pins in the stud members, wherein the pins are encased in a water repellent tube and are arranged to be removed after construction is complete.

2. A wall construction substantially as hereinbefore claimed with reference to Figure 1 or Figure 2 of the accompanying drawings. DATED THIS 1 7 T DAY OF JANUARY 2006. DAVID ALLAN BURKE By his Patent Attorneys LORD COMPANY PERTH, WESTERN AUSTRALIA.
