<div class="application article clearfix" id="description"> New Zealand No. 291351 International No. PCT/AU95/00509 TO BE ENTERED AFTER ACCEPTANCE AND PUBLICATION Priority dates: 18.08.1994;17.03.1995; Complete Specification Filed: 16.08.1995 Classification:^) E04F13/08; E04B2/90.96 Publication date: 19 December 1997 Journal No.: 1423 NEW ZEALAND PATENTS ACT 1953 COMPLETE SPECIFICATION Title of Invention: Brick or tile cladding system Name, address and nationality of applicant(s) as in international application form: THE STEEL BACKED BRICK CO PTY LIMITED, 63/5 The Esplanade, Elizabeth Bay, NSW 2011, Australia 29 1 351 *G&A» 9 5 / 0 05 0 9 ;RECEIVEQ 3 0 AUG iggg ;1 ;BRICK OR TH E* n AnnTNG SYSTEM TECHNICAL FIFT.n The present invention relates to cladding systems for buildings and, more particularly, cladding which in its completed form has the appearance of a solid brick or brick veneer finish. BACKGROUND ART The prior art in this field is exemplified by the disclosure of Australian Patent No. 624139 and International Publication W093/05251, the contents of which specifications are included herein by reference. The prior art arrangement of patent No 624139 suffers some problems and added costs in installation, not the least of which are that the tiles that are used in such an arrangement are required to be slotted on a pair of parallel edges, so that mounting flanges on a mounting plate fit into those slots to retain the tile in position on the mounting plate preparatory to the application of mortar between the bricks. The disclosure of W093/05251 avoids the necessity to use slotted edge tiles but employs a cladding support panel having complicated resilient teeth to retain the tiles in place prior to grouting. The mortar in such applications is typically applied using piping bags, air cartridge guns or low pressure air pots as is known in the art Other prior art arrangements, as shown in W087/02088, have proposed support sheets for brick tiles or similar where the tiles are adhered to the sheet via adhesive with grouting placed between the mounted tiles to provide a desired aesthetic finish while the adhesive functions to permanendy fix the tiles to the sheet DISCLOSURE OF INVENTION The present invention recognises that the complexity of the mounting plate and tiles of the prior art are unnecessary and proposes a much simplified and less costiy arrangement which employs a mounting plate or cladding support panel of the general form of that shown in Australian patent No 624139 but wherein the mounting flanges are provided as ledges or shelves which project normally to the plane of the plate and function to provide a support surface for the bottom edge of a tile as in W087/02088. In accordance with the present invention there is provided a mounting plate for tiles adapted to provide a cladding component comprising a generally planar sheet panel comprising a plurality of shelves or ledges in spaced apart mutually parallel rows, AMENDED SHEET 1PEA/AU per/Ail 95/0050^ RECEIVED 1 8 OCT 1996 2 said plate being used such that during fixing of tiles to said planar sheet panel said shelves or ledges adapted to support lower edges of tiles rested thereon without any interfitment or resilient engagement between the lower edges of the tiles and the shelves or ledges such that the tiles are supported to rest against the panel and remain so without any adhesive interposed between the tiles and the planar sheet panel, a plurality of openings through said panel being adapted to provide for passage of grouting material applied between adjacent tiles when supported on said ledges, such that in use said grouting material passes through said openings to act as the only fixative between the tiles and the panel by keying the tiles to the openings in the panel as well as acting as a grout between adjacent edges of adjacent tiles. By means of the present invention the use of adhesive behind the tiles as a temporary or permanent fixative is eliminated. Fixing of the tile to the mounting plate is achieved by grouting applied between adjacent tiles such that openings or cut-outs in the mounting plate provide for passage of the grouting through the plate to key the tiles to the plate and facilitate permanent fixing of the tiles to the plate. In an embodiment the ledges are inclined upwardly from the horizontal, when the plane of plate is vertically oriented, so as to act to locate a tile against the plate when the tile is rested against a ledge or a plurality of ledges in the same horizontal alignment A preferred incline for the ledges of this form of the present invention is upwardly at about 8° from the horizontal when the plane of the plate is vertically disposed. Once the mortar has been applied between the tiles such that it passes back to the plane of the mounting plate and keys through openings formed in the mounting plate adjacent the tiles, the assembly of the mounting plate, tiles and mortar form a coherent structure which provides substantial resistance to cracking of individual tiles. In the present invention the grouting between tiles to key the tiles to the plate provides not only an aesthetic affect but a functional imperative not previously contemplated as an adequate permanent fixative to hold tiles to the mounting plate in use as a cladding panel. By considering the form of the mounting plate shown in the drawings of patent No 624139, it can be seen that an embodiment of a first form of the present invention relative to Fig. 6 of that patent specification is required to have the flanges 14 formed as base portions 16 without "a tile engaging lip 17", 29135 1 amended sheet IPEA/AU _ pct/au 9 5 / 0 0 5 0 9 29 1 3 51 '8 0CT ®® while doing away entirely with flanges 15 and having openings in the plate so as to enable the grouting to key the tiles to the plate by passing through those openings then setting. In one embodiment the mounting plate comprises a plurality of shelves 5 as aforesaid. In another embodiment the present invention consists in a cladding assembly comprised of at least one mounting plate as aforesaid holding bricks or tiles with grouting applied to form a coherent integrated unit BRIEF DESCRIPTION OF DRAWINGS 10 The present invention will now be described by way of example with reference to the accompanying drawings, in which: Fig 1 is a perspective view of a mounting plate of an embodiment of the present invention; Fig 2 is a front elevation of the plate of Fig 1; 15 Fig 3 is a p?an view of the plate of Fig 1; Fig 4 is a side elevation of the plate of Fig 1; Fig. 5 is a side elevation of the plate of another embodiment of the invention and Fig. 6 is the same view as Fig. 5 but with tiles in place ready for the 20 addition of grouting mortar therebetween. BEST MODES The mounting plate 10 as shown in the drawings comprises a planar section 11 adapted to be mounted to an existing wall surface via battens or similar or to wall framing. Mounting plate 10 comprises a plurality of shelf 25 members 12 cantilevered out from one surface of the planar member 11. Shelves 12 are formed by punching out portions of planar member 11 which are hingedly bent out of the plane of the member 11 and adapted to receive a plurality of tiles 13 in a suitably aligned arrangement. Tiles rest on shelves 12 and are held in their respective relative 30 positions by the addition of grouting mortar between tiles. The grouting mortar keys the tiles to plate 10 by passing through openings 15 and the openings left by displacement of shelves 12 being from the plane of member 11. In the embodiment of Figs 5 and 6 tiles 13 rest on shelves 12 and are 35 held in their respective relative positions by the upward incline (a) of shelves ^msnqeq sheet 'psa/au i 29 1 35 V 12 which act to retain the tiles in situ against planar member 11 preparatory to the addition of grouting mortar between tiles 13. The incline of shelves 12 is relevant to the functioning of the embodiment while forming a cladding panel when member 11 is 5 vertically oriented only insofar as shelves 12 serve to hold tiles 13 in place against member 11 preparatory to grouting. A typical incline may be 5°-10° but any incline that is suitable for achieving the desired results is appropriate. Plate 10 may comprise stiffening ribs to give added rigidity to the 10 plate as well as additional holes 15 or openings to those provided by the formation of shelves 12 so as to provide additional keyways for the mortar to pass through the plate 10 to provide added structural integrity to the finished assembly. INDUSTRIAL APPLICABILITY 15 The present invention has particular suitability for use in earthquake prone regions. A timber, metal or bamboo framed structure could be readily cladded with a cladding support panels or mounting plates of the present invention having tiles, brick panels or cladding pieces affixed to the panel via grouting which also keys the tiles etc to the 20 panel. Upon the occurrence of a quake or tremor the framing of the building may flex causing some or portions of the tiles to break their keyed connections with the panels but repair to the veneer of the structure is easy and relatively inexpensive. It will be appreciated by a person skilled in the art that numerous 25 variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive. pct/au 95/00509 1 3 5 1 s::c;vio ; ?v.-. aa 5 </div>
