ABSTRACT:
This invention relates to wall facing systems of the type including horizontally elongate facing plates of stone material supported by mounting bars adapted to be secured in a vertical position on a building wall. More particularly, the invention relates to a wall facing system of the kind set forth in the precharacterizing portion of the independent claim.
A wall facing system of that kind is known from, for example, W
0
92/08857.
In an embodiment of the prior art system which is now available on the market, the length of the facing plates or tiles is 300 mm, alternatively 600 mm, and their height (width) and thickness are respectively 100 mm and 30 mm. They are artificial stones made from granular marble, cement and pigment.
As will be readily appreciated, the facing tiles have a considerable weight. Because of the weight, on the order of 50 kg per square meter of faced wall surface, the costs for transporting the tiles from the manufacturing site to the building site amount to a substantial percentage of the total cost for the facing, especially if the tiles have to be transported over a long distance.
Because of the high costs of transportation it is hardly economically feasible to export the tiles, possibly with the exception of nearby export markets. In certain cases, even the costs for domestic transports may make the system economically unacceptable.
Given the nature of the material of the tiles, a reduction of the thickness of the tiles offers the only possibility of reducing the weight of the tiles. However, a reduction of the thickness is not readily feasible, because the manner of mounting the tiles on the wall necessitates a certain minimum tile thickness, in order that the strength of the plates may not be inadequate. Although it would be possible to reduce the weight by making the thinned lower part of the front portion of the tiles higher (wider) and correspondingly reducing the height (width) of the rear tile portion, the increased height of the lower part of the front portion would substantially increase the danger of damaging the tiles. In addition, the surface by which the rear side of the mounting part of the tiles, i.e. the portion of the rear face of the tiles which is above the support rib, engages the mounting bar, would be smaller (narrower), so that the plate would not firmly engage the mounting bars.
The present invention provides a solution whereby the weight of the tiles may be substantially reduced, by up to about 50 percent, by reducing the thickness of the tile over a substantial portion of the height of the tile, while at the same time balancing the consequent reduction of the strength of the tile by improving the support provided for that thinned tile portion by the mounting bars.
