Description

FIELD OF THE INVENTION

[0001] The present invention relates in particular but not exclusively to a versatile prefabricated panel building system incorporating wall panels having a roller track sliding means and an integrated stud assembly which confers substantial rigidity and integrity and which significantly reduces construction time by dispensing with traditional and prior art stud framing. The lightweight construction of the panels are such that they can also be prefabricated or manufactured on site in a portable or re-locatable factory or plant from raw and component materials thereby further reducing or eliminating time and transport costs.

BACKGROUND OF THE INVENTION

[0002] The main disadvantage of prior art prefabricated wall building systems is that they require labor and time in which to erect traditional stud framing, to affix wall cladding panels, insert insulation material and then render, sand and paint the finished product. Furthermore, prior art composition boardroom wallboard panels are not designed for convenient water and electricity installation. Water pipes and electric cables are usually installed on the outside surface of prior art panels. While it is possible to install water pipes and electric conduits under the panel surface, this requires cutting into the surface and then having to restore and redecorate the panel post installation. If this is not skillfully undertaken, the repair work will not only be unsightly, but may result in permanent damage to the structural integrity of the panel thereby degrading overall performance. Most prior art wallboard panels have poor weight bearing capacity. Upright walls constructed from these panels inevitably have poor wind shear load resistance.

[0003] Existing composition panels must also be able to withstand diagonal torsion or twisting forces according to various relevant municipal building regulations and requirements. This results in prior art wallboard panels having to be of a substantial construction which are not conducive to being prefabricated on site which is not only costly but is often also aesthetically less pleasing in appearance.

[0004] In view of the above-mentioned limitations, it is an object of the present invention to overcome the disadvantages of the prior art by providing & novel prefabricated wall panel building system which confers substantial rigidity and integrity and which is also characterized by relatively speedy installation and construction, high fire resistance, high weight bearing capacity, good sound, insulation and most importantly, is cost effective relative to performance when compared to existing and traditional building systems.

DETAILED DESCRIPTION OF EMBODIMENTS

[0059] As shown in the following drawings, the invention aims to provide a novel and versatile prefabricated panel building system characterized by fast installation, rapid construction, high fire resistance, high weight capacity, high cost performance and good sound insulation when compared to the prior art. The present invention comprises a plurality of wallboard panels joined together. Each panel 10 as typically shown in FIG. 1 includes specially adapted interlocking edge members 12,14 having complementary profiles configured to be interlocked with the edge members of adjoining panels (not shown) to form integrated stud or cross members. The resulting integrated arrangement conferring substantial rigidity and integrity to the erected structure.

[0060] The preferred panel includes an inner waif decoration layer, a fiber calcium silicate board, a thermal-protective layer and an external wallboard cladding, which are preferably arranged in this sequence. A gap is preferably provided between the external wallboard cladding and the thermal-protective layer. In a preferred example, the thermal-protective layer is made up of PU or EPS foaming as a thermal insulation layer. The fiber calcium silicate hoard which is in contact with the thermal-protective layer is located between the thermal-protective layer and the external wallboard cladding. The external wallboard cladding is comprised of a base plate of fiber calcium silicate board and an external aluminum composite plate glued to the base plate. The edge members can have passages (not shown) extending their length wherein water and electric pipe and lines can be installed. Both top and bottom ends of the panels are provided with integrated rollers 20,21 and 23, 25 which engage tracks of the building's frame (not shown) whereby adjacent panels are able to be slid into position against each other.

[0061] FIG. 2 shows partial detail of adjacent panels 16, 18 about to be joined by clipping together their respective complementary serrated longitudinal edge members 12, 14.

[0062] Both top and bottom (not shown) ends of the panels are provided with integrated rollers 20,22 which engage tracks of the building's frame (not shown) whereby adjacent panels are able to be slid into position against and on top of each other thereby substantially reducing onsite assembly time. In the alternative to rollers, skids or buttons of an anti-friction material such as Teflon may be used.

[0063] FIG. 3 shows detail of a pair of complementary serrated longitudinal edge members 24, 26. The edge members which when clipped together comprise an integrated stud are aluminum extrusions incorporating a tongue profile 24a and a groove profile 26a wherein the grooves are serrated to lock the panels (not shown in this view) when pushed together. There are also one or more slots 28,30 adapted to receive a barbed bracket or mounting member for the mounting of accessories, including lights, ornaments, removable cladding and decorative panels.
