Abstract
Abstract Facings for use as building components with a solid molded part constituting the visible side and a foam member of an inorganic and/or organic foam can be produced by shaping and heat curing from inorganic, aqueous molding compositions, wherein the molding composition contains a reactive oxide mixture, an alkali silicate solution, optionally alkali hydroxide, and fillers and auxiliary agents.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
90 words
A facing for use as a building component comprising a solid molding having a visible part of a cured, inorganic molding composition with a specific gravity of 1.3-2.5 g/cm 3 produced from: 10-30% by weight of an aqueous, potassium-alkaline potassium silicate solution; 15-40% by weight of a reacitve pulverulent oxide mixture with contents of amorphous SiO 2 and aluminum oxide; and 20-75% by weight of fillers; and a foam member bonded to the visible part, said foam member having a foamed structure comprised of an inorganic or organic foam material.
Claim 2
Dependent Claim
90 words
A facing for use as a building component comprising a solid molding having a visible part of a cured, inorganic molding composition with a specific gravity of 1.3-2.5 g/cm 3 produced from: 10-30% by weight of an aqueous, potassium-alkaline potassium silicate solution; 15-40% by weight of a reacitve pulverulent oxide mixture with contents of amorphous SiO 2 and aluminum oxide; and 20-75% by weight of fillers; and a foam member bonded to the visible part, said foam member having a foamed structure comprised of an inorganic or organic foam material.
Claim 3
Dependent Claim
99 words
A facing for use as a building component according to claim 1, wherein a projecting rib flush with the underside of the solid molding is molded to a solid body portion, which body portion is fashioned with rectangular basal area, along two successive sides, and the foam member is fashioned, in the zone of the ribs, to be in alignment with the sides of the body portion and projects past the molding body portion alongside the two sides of the body portion that are free of a rib, with a width corresponding approximately to the width of the rib.
Claim 4
Dependent Claim
86 words
A facing for use as a building component according to claim 1 wherein the foam member consists of an inorgainc, cured and foamed panel, said panel having been prepared from a molding composition containing: 20-60% by weight of an aqueous, potassium-alkaline potassium silicate solution; 30-80% by weight of a reactive, pulverulent oxide mixture with contents of amorphous SiO 2 and aluminum oxide; 0-50% by weight of fillers; and 0.5-5% by weight of a blowing agent with a gas formation temperature of between 20° and 95° C.
Claim 5
Dependent Claim
89 words
A facing for use as a building component according to claim 2 wherein the foam member consists of an inorganic, cured and foamed panel, said foamed panel having been prepared from a molding composition containing: 20-60% by weight of an aqueous, potassium-alkaline potassium silicate solution; 3- 80% by weight of a reactive, pulverulent oxide mixture with contents of amorphous SiO 2 and aluminum oxide; 0-50% by weight of fillers; and 0.05-5% by weight of a blowing agent with a gas formation temperature of between 20° C. and 95° C.
Claim 6
Dependent Claim
38 words
A facing for use as a building component according to claim 3, wherein said composition contains as the blowing agent 0.5-4% by weight of sodium perborate or H 2 O 2 , respectively, based on the molding composition.
Claim 7
Dependent Claim
38 words
A facing for use as a building component according to claim 4, wherein said composition contains as the blowing agent 0.5-4% by weight of sodium perborate or H 2 O 2 , respectively, based on the molding composition.
Claim 8
Dependent Claim
31 words
A facing for use as a building component according to claim 3, wherein said composition contains as the blowing agent 0.05-0.8% by weight of pulverized aluminum, based on the molding composition.
Claim 9
Dependent Claim
31 words
A facing for use as a building component according to claim 4, wherein said composition contains as the blowing agent 0.05-0.8% by weight of pulverized aluminum, based on the molding composition.
Claim 10
Dependent Claim
63 words
A facing for use as a building component according to claim 1, wherein said molding composition contains, as the fillers in finely divided form, rock flours, basalts, clays, feldspars, ground mica, ground glass, quartz, bauxite, hydrated alumina, wastes from the alumina, corundum, bauxite manufacture, ashes, slag, fibers such as synthetic resin fibers, mineral fibers, vermiculites, ground pumice or the like, and mixtures thereof
Claim 11
Dependent Claim
30 words
A facing for use as a building component according to claim 1 wherein the visible surface of the visible part is fashioned to be textured, embossed, decorated or the like.
Claim 12
Dependent Claim
29 words
A facing for use as a building component according to claim 1, wherein reinforcing inserts of metal and/or synthetic resins and/or glass fibers are provided in the molding composition.
Claim 13
Dependent Claim
24 words
A facing for use as a building component according to claim 2, wherein the foam member consists of polystyrene, phenolic resin, or polyurethane foam.
Claim 14
Dependent Claim
48 words
A wall arrangement comprised of the facing according to claim 2 wherein one of the facings is positioned vertically above another with the rib of the lower facing contacting both a bottom surface of the body or the upper facing and a front surface of the foamed member.
