Abstract
Abstract A building wall panel (14) is adapted to be mounted directly on the framework of a building and includes an exterior facing composed of thin, presized masonry panels (16) of, for instance, granite or marble, mounted on a support frame (18) by a plurality of attachment assemblies (24). Each attachment assembly (24) also includes a first subassembly composed of a pair of studs (30) extending diagonally rearwardly from panel (16) to extend within a pocket (28) defined by an enclosure member (26) of a second attachment subassembly secured to the support frame (18). The studs (30) together form a forwardly open bight which loops around a crosspin (32) extending through the enclosure member, through the interior of pocket (28) to engage with support frame (18). Pocket (28) is filled with a bonding medium (34) that creates a rigid interconnection between studs (30) and support frame (18).
