Abstract
ABSTRACT
A method of weatherproofing building panels is described. The method is straightforward and utilizes readily available materials. The invention is particularly useful with imitation brick panels of the interlocking type which are presently employed to clad houses so as to give an appearance of an all brick dwelling. Field tests showed that wall panels sealed by the present invention remained weatherproof despite movement caused by timber shrinkage and foundation settlement.

Description
~833Z~
The present invention relates to building panels used for the external walls of dwellings and like buildings, and more particularly to methods of joining these panels to form weatherproof walls.
In the construction of such buildings, it is common practice to use bricks for the external walls - however, brick constructions use expensive materials, are time consuming during erection, and hence expensive in labour utilisation. To save costs, and to speed up construction, various other materials are used for external walls, e.g.
asbestos-cement and timber. Unfortunately, these materials per se are not architecturally attractive, and suffer from the disadvantage of requiring continuing maintenance, such as painting.
To overcome these difficulties of appearance and maintenance with the cheaper materials, it has been proposed to construct external walls of preformed panels, comprising a backing material of asbestos-cement or the like, and a facing formed thereon giving the appearance of brick or natural stonework, e.g. the "Stepart" panel.
Stepart is a trade mark, owned by Stepart Sales & Service Pty. Ltd. of Sydney, New South Wales. The Stepart panel may be described as an imitation brick panel with the ends of adjacent panels abutting in interlocking relationship whereby the junction between the panels is not apparent. Such a ~3 panel is described in Australian Using preformed panel construction involves sealing problems along the panel edges where adjacent panels are joined. Usually the problem has been solved - albeit

unsatisfactorily - by using strips of mashing materials (such as tape, paper, synthetics~ along the joints at the backs of the panels, in conjunction with a sealing compound such as a putty along the joint itself. The panels are, of course, abutted along a stud, where the join is vertical, for support, or along a trimmer board or nog~gin where the join is horizontal, although in the teaching of this invention, horizontal joints need not be backed by a trimmer board or noggin.
As stated, the prior art solutions are unsatisfactory, since subsequent movement of the studs and trimmer boards tends to open up the joins, thus permitting entry of water during periods of rain b~hind the panels to the timber frame of the dwelling.
It is an object of the present invention to provide a method o~ forming the external walls of framed dwellings and like framed buildings from preformed panels in such a way that the panel joints are fully sealed against ingress of water, thus rendering the walls r of the dwelling completely weatherproof. The invention also comprehends within its scope a wall construction, and a framed dwelling or like framed building incorporating such wall construction, wh~ich has been made by the method disclosed herein.
Thus, one aspect of the invention provides a framed dwelling or like framed building comprising external walls of preformed panels, said panels respectively having abutting vertically extending edges arranged to overlie respective studs of the external wall frame, a riqid, flat, metal backing member fastened to each stud, said panels being adhered by a waterproof adhesive to respective backing members and said backing members extending the full length of ~8 abutting edges of the panels glued thereto whereby to form weather-

Another aspect of the present invention provides a method of constructing the external walls of framed dwellings or like framed buildings from preformed panels comprising affixing rigid, flat, metal backing strips to the studs of ~he external wall frame, the backing strips extending laterally both sides oE the studs to which they are affixed, affixing a rigid metal backing strip of an~ular cross-section to the corner studs at each corner of the frame, adhering by a waterproof adhesive pairs of preformed panels with vertically extending abutting edges to each backing member whereby all such edges overlie respective backing members, and the backing members extending the full length of such edges, driving fastening members through the panels into the studs, and inserting flashing strips between horizontally extending abutting edges of the panels, the flashing strips being fastened to the studs and/
or the trimmer boards of the external wall frame, whereby to form weatherproof joints.
A better understanding of the invention will be gained by reference to the drawings which illustrate preferred embodiments of the invention and are not intended to be restrictive of the 28 broad scope of the invention. In the drawings:

Figure 1 illustrates a pair of preformed panels of the interlocking type with an imitation ~rick facing, Figure 2 illustrates part of the frame of an external wall of a dwelling, Figure 3 and 3a are front and side views of a pair of panels having a horizontal joint, Figure 4 is a horizontal cross-section of the corner structure of a dwelling in accordance with the present invention~
In Figure 1 a pair of interlocking panels 1 and 2 are is position for abuttment to form a vertical joint. The panels comprise a facing of imitation bricks 4 on a backing 5 (Figures 3, 3a) of a material such as asbestos-cement.
In Figure 2 the wall frame can be seen to comprise vertical studs 6, and trimmer boards or noggins 7, extending more or less horizontally between the studs. Member 8 is a metal plate (suitably galvaniæed iron or steel) extending the full length of that part of the stud to which the wall panels are to be attached.
Items 9 are nails or similar fastening means affixing the plate to the stud. Other plates (not shown) are similarly fixed to the ~a other studs of the wall frame. The joints of adjacent panels are arranged to lie rw/~ - 4a -.,, ., :. . ,: :,- : -.:

along metal plates 8, which are coated with a waterproof adhesive, preferably an epoxy resin such as "araldite"
(araldite is a registered trade mark), the panels are then fitted together over the plates and nailed or screwed through them to the studs. Similarly horizontal joints between adjacent panels can be arranged to lie along the trimmer boards or noggins, and these joints are then constructed and sealed in the same way as are the joints lying along the studs.
Alternatively, referring to Figures 3, 3a, horizontal joins ~etween qdjacent panels need not lie along trimmer boards or noggins. Simply, a metal 1ashing 10 is fixed by a fastener 11 to stud 6. This flashing e~tends the full length of the join around the dwelling - clearly member 10 will not be a single piece but may be formed of a number of flashing lengths overlapping at their respective adjacent ends. Clearly, this flashing will prevent ingress of water through the joint to behind the panels.
At the corners of the dwelling (see Figure 4) a pair ~0 of wall plates 12 meet studs 6. The member equivalent in function to plate 8 is metal angle member 13, which encloses the corner studs, and is affixed thereto. A pair of panels 14 and 15 intersect at the corner to form a vertical joint, and these panels, as before, are adhered by a waterproof adhesive to member 13, and nailed, screwed or otherwise to respective studs 6.
Thus it can be seen that due to the nature o~ the backing plates, and the manner of adhering the panels there-to, as well as fastening the panels to the studs, a dwelling 10833Zl wall can be formed which is quite weatherproof, and will remain so despite movement of the frame members caused by timber shrinkage or foundation settlement. In this way the prior art problems are obviated.
It will be evident to those skilled in the art that various modifications can be made to the preferred methods and wall construction described above, e.g. the plates 8 and 13 need not be galvanised iron or steel. It is important that they be sufficiently rigid and strong to maintain support of the panels in the region of the joining area.
Similarly, plates 8 and 13 need not be formed of a single length, but could comprise a series of members with over-lapping ends.
It should be noted that the invention is applicable to wall constructions using, e.g., plain sheet material such as asbestos-cement as it is to preformed panels with decorative facings.
As mentioned previously, the preformed panels are preferably of the Stepart type. However, other panels ~0 which may or may not interlock are satisfactory. Desirably the~backing is a 26 gauge hot dipped galvanised iron strip 180 mm. wide. The studs are normally 100 mm. by 50 mm. and the clouts used are desirably 25 mm by 14 gauge large head galvanised type. The adhesive preferred is araldi-te - an epoxy type substance but other adhesives or cements may be used.
