5176 5 9 PATENTS FORM 5 Our Ref: 583517NZ PATENTS ACT 1953 Dated: 6 March 2002 COMPLETE SPECIFICATION Building Panel We, CSR Limited, an Australian company, ACN 000 001 276, of Level 1, 9 Help Street, Chatswood, New South Wales 2067, Australia, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: INTELLECTUAL PROPERTY OFFICE OF N.Z. > 7 MAR 2002 RECEIVED [R:\LIB W]46493.doc:jng 1 BUILDING PANEL Technical Field The present invention relates to building panels and more particularly to panels used to form walls of buildings.

Background of the Invention Typically external and more particularly internal walls are supported by a frame consisting of a top and bottom plate between which stud members pass. Sheet material such as plasterboard is then secured to the frame so as to be supported thereby. In particular, each plasterboard sheet would be supported by a plurality of the stud members as well as the top and bottom plate.

The above typical wall structure has the disadvantage that it is reasonably low security. It is relatively easy for an intruder to destroy part of the plasterboard in order to provide a passage. This is of particular prominence when such walls are used to separate adjacent premises or hotel rooms.

Object of the Invention It is the object of the present invention to overcome or substantially ameliorate the above disadvantages.

Summary of the Invention There is disclosed herein a building panel for a wall, said panel including; a metal sheet having opposite major surfaces and to be generally vertically oriented so as to have a top and a bottom edge and generally vertically extending side edges, a plurality of ridges extending generally vertically and parallel to the side edges but transversely spaced, said ridges extending from one of said major surfaces; and a generally planar sheet member extending from the other major surface.

Preferably the metal sheet is corrugated so as to provide said ridges.

Preferably said corrugations have planar portions providing said major surfaces.

Preferably said planar sheet member is plasterboard.

Preferably said building panel is incorporated in a wall in which the building panel is supported adjacent its periphery only.

Brief Description of the Drawings A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein: Figure 1 is a schematic section side elevation of an internal building wall; Figure 2 is a schematic top plan view of a portion of the wall of Figure 1; Figure 3 is a schematic top plan view of a modification of the wall of Figure 1; and Figure 4 is a further schematic top plan view of a modification of the wall of Figure 1.

Detailed Description of the Preferred Embodiments In the accompanying drawings there is schematically depicted a wall 10 which would be typically an internal dividing wall of a building. The wall 10 extends between a floor 11 and ceiling 12. Attached to the floor 11 is a bottom plate 13 while attached to the ceiling 12 is a top plate 14.

The wall 10 includes a metal sheet member 15 that in this instance is corrugated so as to have longitudinally extending ridges 16. The ridges 16 extend from a major surface of the sheet member 15, which major surface is provided with flat portions 17.

Secured to the flat portions 17 by means of fasteners 18 or adhesive is a planar sheet member 19 which in this preferred embodiment is a sheet of plasterboard.

The sheet member 15 and plasterboard 19 form a building panel 20 which is supported adjacent its periphery only by means of vertically extending studs adjacent the vertical edges, and by the top and bottom plates 13 and 14. That is there are no stud members located between the vertically extending edges of the building panel 20.

In the embodiment of Figure 3 the wall 10 has two sheet members 15 and two plasterboard sheets 19 and further incorporates an insulation layer 21.

In the embodiment of Figure 4 there is no insulation layer 21.

In the above-described preferred embodiments the building panel 20 provides a number of advantages: 1. increased security in that the metal sheet member 15 inhibits penetration; 2. increased fire protection; 3. increased strength; and 4. elimination of studs intermediate to the edges of the building panel.

Typically the above-mentioned building panel 20 would be delivered to a building site with a plurality of the sheet members 19 secured in a stack and the metal members 15 3 secured in a separate stack. This ideally minimises the volume of material being transported. The panel 20 would be assembled on site.

Claims (7)

4 The claims defining the invention are as follows:

1. A building panel for a wall, said panel including: a metal sheet having opposite major surfaces and to be generally vertically oriented so as to have a top and a bottom edge and generally vertically extending side edges, a 5 plurality of ridges extending generally vertically and parallel to the side edges but transversely spaced, said ridges extending from one of said major surfaces; and a generally planar sheet member extending from the other major surface.

2. The panel of claim 1 wherein the metal sheet is corrugated so as to provide said ridges. 10

3. The panel of claim 2 wherein said corrugations have planar portions providing said major surfaces.

4. The panel of claims 1, 2 or 3 wherein said planar sheet member is plasterboard.

5. A wall incorporating the building panel of any one of claim 1 to 4 wherein 15 said building panel is supported adjacent its periphery only.

6. A building panel substantially as hereinbefore described with reference to the accompanying drawings.

7. A wall substantially as hereinbefore described with reference to the accompanying drawings. 20 CSR Limited By Attorneys for the Applicant SPRUSON & FERGUSON BUILDING PANEL Abstract A wall 10 to extend between a floor 11 and ceiling 12. The wall 10 includes a metal sheet member 15 that is corrugated so as to have longitudinally extending ridges 16. The ridges 16 extend from a major surface of the sheet member 15, which major surface is provided with flat portions 17. Secured to the flat portion 17 by means of fasteners 18 or adhesive is a planar sheet member 19 which in its preferred form is a sheet of plasterboard.
