Name of Applicant: RUSLING INVESTMENTS PTY. LTD.
Actual Inventor(s): DEAN MORELAND RUSLING Address for Service: SANDERCOCK COWIE SUITE 8C, 50-54 ROBINSON STREET DANDENONG VIC 3175 Invention Title: BUILDING PANEL Details of Associated Provisional Application(s): No(s): Australian Provisional Application No. 2004906986 Filed: 7 th December, 2004 The following statement is a full description of this invention, including the best method of performing it known to us: -1- R2c2O5-2-077.Z:Fingning.fie.wpd. I -la- BUILDING PANEL
TITLE:
FIELD OF THE INVENTION This invention concerns building panels and particularly those suitable for flooring.
BACKGROUND OF THE INVENTION It is common to build suspended floors in stages. A series of mutually parallel timber bearers are secured to the floor piles and a series of mutually parallel floor joists are 2005. 12-O7,Z:Spcifiicationsilusit8&capmwpd, I -2- Snailed to the bearers at 900 to the direction of the bearers. Floor panels or floorboards are
U
Sthen glued or nailed to the joists at 90* to the direction of the joists. This construction results in a load bearing floor of suitable strength because the bearers are at 1800mm 00 Scentres, joists at 400mm centres. This is a span suited to the strength of the flooring panels or strips supplied by manufacturers for this purpose.
Suspended floors require underfloor insulation if they are to contribute to energy savings Nin the building. They impose loading restrictions. They may bum through quickly in a fire and if the floor is an upper floor, will collapse onto a lower floor.
C GB 2 156 874 describes a composite floor for laying on top of parallel concrete bearers bridged by timberjoists which span adjacent pairs of bearers. The tops of the bearers and the tops of the joists lie in a common plane. Thin sheets of polystyrene are laid on the bearers andjoists and a layer of flooring grade chipboard is laid on top of the polystyrene.
Square-section service ducts beneath the floor are accessed through hatch covers. The floor is dry laid using acrylic adhesive. The strength of the floor is limited to the loading capability of the chipboard and this in turn dictates the spacing of the bearers.
SUMMARY OF THE INVENTION The apparatus aspect of this invention provides a building panel comprising a top sheet made of timber, timber derivative, plastic or cellulose/cement sheet and a bottom sheet made of sheet metal both joined face to face to a core sheet of polymeric foam.
The top sheet may be a base sheet to which a further floor layer such as flooring strip may be attached. The top sheet may therefore be plywood or fibreboard. Instead the top sheet may be particle board to which vinyl sheet may be glued. Particle board would take staples for carpet underlay. Consequently the thicknesses of the top sheet material tend to be those of commercially available fibreboard or particle board products.
The bottom sheet may be planar or undulating. The sheets may be serrated, corrugated, grooved or castellated to increase the stiffness in one direction so as to improve the spanning ability of the sheet. The metal may be steel or aluminium or an alloy. A 2005.-12-07Z:'Speciftionszusling.cAp.wpd,2 o -3c thickness range of 0.4-1.0mm suffices for domestic floors at 1900mm support centres.
O
0 Office and commercial floor panels take the greater thickness.
00 O The core is preferably expanded polystyrene beads but could be a solid constructional foam of the type used in constructing large span roof panels or coolroom panels.
Thicknesses of 75-100mm suffice for domestic, commercial and office panels. Larger spans require thicker panels. The top and bottom sheets may be fixed to the core sheet Swith adhesive, suitable examples of which are in the literature.
in 10 BRIEF DESCRIPTION OF THE DRAWINGS One embodiment of the invention is now described with reference to the accompanying drawings, in which: Figure 1 is a cross section of a floor panel.
Figure 2 is a side view of a floor panel as shown in Figure 1 and as a suspended floor.
Figure 3 is a perspective view of the panel of Figures 1 and 2.
DETAILED DESCRIPTION WITH RESPECT TO THE DRAWINGS Referring now to Figure 1, the top layer 2 of the composite panel comprises 2400 x 1200mm sheets of 18mm particle board. The base layer 4 is made of 0.6mm corrugated steel of square wave section. The corrugations 6 are 20 x The core 8 is made of polyurethane foam and is 75mm thick. The core is 1200mm wide, whereas the steel layer is wider, projecting as a margin 10, one and a half corrugations beyond the edge 12. This allows a companion panel to be placed adjacent with one and a half corrugation overlap and contiguous edges. The 2400mm edges of the particle board have grooves 14, 16 which take plastic tongues or a glue in bead 18 in order to align the joint between adjacent panels.
2005-12O7.Z:SpcifwlcaiomVusing.cap.wpd.3 -4- The manner of building a suspended floor is seen in Figure 2. A series of 100 x 50 joists are fixed at 1900mm centres to stumps 22. Panels are laid at 90' to the joists.
Adhesive is applied to the exposed margin of each panel and the panels overlapped as they are laid. The panels are fixed to the joists by countersunk screws 24.
Fastening is done by screwing the building panel through from top to bottom into the supporting bearer and by glueing laps on butt joints of upper and lower sheets.
We have found the advantages of the above embodiment to be: 1. The floor has high thermal insulation.
2. The top layer takes all conventional flooring materials.
3. Portions of the floor may be excised by a portable power saw to take vents, ducts and the like.
It is to be understood that the word "comprising" as used throughout the specification is to be interpreted in its inclusive form, ie. use of the word "comprising" does not exclude the addition of other elements.
It is to be understood that various modifications of and/or additions to the invention can be made without departing from the basic nature of the invention. These modifications and/or additions are therefore considered to fall within the scope of the invention.
