Claim:
A dry joint wall panel attachment system for attaching multiple wall panels to an exterior building wall, each wall panel having a dead load, and the system comprising: a plurality of wall panels, each wall panel having an exterior flat surface and at least two side surfaces bent generally perpendicularly to the exterior flat surface and defining a hollow interior portion; a plurality of bracket assemblies configured to be fastened to the exterior wall; a plurality of attachment clips configured to be fastened to respective bracket assemblies by a fastener and to carry the dead loads of the respective wall panels, each attachment clip having a central fastening surface fastened to the bracket assembly and a pair of integrally formed wing members, each wing member extending outwardly from the central fastening surface in a substantially symmetrical manner; a plurality of panel perimeter strips configured to be fastened to one side surface of a respective wall panel, each panel perimeter strip comprising: a generally C-shaped member configured to reside inside of and extend along an inside portion of a side surface of a respective wall panel, and a receiving member integrally attached to the C-shaped member configured to extend beyond the side surface of a wall panel and provide a slot adapted to engage and interlock one of the wing members of the attachment clip, thus operatively connecting a respective wall panel to the attachment clip and, thereby, to the wall; one or more rivets provided along the side surface of respective wall panels to connect the side surface to the receiving member of a respective panel perimeter strip; a plurality of infill strips non-sealingly disposed within respective slots of the panel perimeter strips between the corresponding attachment clip and the one or more rivets so as to cover the fastener, each infill strip being fabricated from a substantially rigid material comprising aluminum, polyethylene, or combinations thereof; wherein: the system is held together non-adhesively, the system is configured to allow wall panels to be secured to respective panel perimeter strips in any sequence, and each wall panel is ventilated at least partially through the one or more rivets to permit ingress and egress of air and moisture to provide a pressure-balanced and moisture-drained interior environment.
