Abstract
A building wall panel (20) adapted for mounting on a building frame includes an exterior facing formed from a plurality of thin stone panels (22) of for instance granite or marble, backed and interconnected by a layer (28) of glass fiber-strengthened concrete underlying the panels and covering and engaging anchor clips (24) secured to the backs of the stone panels (22). The backing layer (28) is bonded to a metal support frame (30) by additional amounts of glass fiber-reinforced concrete (29) overlaying portions of anchor members (36) carried by the support frame and adjacent portions of the backing layer (28). A method of forming the building wall panel (20) involves placing granite or marble panels (20) face down in a form (48), mounting anchor clips (24) or pins (61) in the backs of the stone panels, and spraying a layer of slurry (55) formed from a mixture of concrete and chopped glass fiber strands, over both the panels (22) and the anchor clips (24 ) or pins (61). A metal wall panel support frame (30) is placed over the backing layer (28) so that anchor members (36) carried by the frame (30) abut the backing layer (28). Next, additional amounts (29) of the slurry (55) are app…
