Abstract
Abstract A panel wall assembly comprises rectangular pan-like panels mounted close together side by side and end to end. Retainers located at all junctures between the panels are fastened to the building structure, and the panels are fastened to the retainers by clips having arms that extend out through slots in the panel flanges. Troughs on each horizontal retainer drain condensate or water that leaks through seals between adjacent panels to drainage slots in the vertical retainers. Gaskets between the retainers and the panel flanges provide additional control of water flow behind the panel faces.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
249 words
An exterior panel wall assembly having a multiplicity of rectangular pan-like panels arranged in closely spaced-apart relation side by side and end to end, each panel having a principal wall forming a portion of an exterior building wall and a continuous peripheral flange extending inwardly from the principal wall toward the building structure, an elongated vertical retainer joined to building structure and located at and coextensive with each vertical flange of each panel and an elongated horizontal retainer joined to the building structure and located at and coextensive with each horizontal flange of each panel, each retainer having a web portion that at least partly overlaps a portion of the flange of each panel adjacent to it and a lateral seating flange portion extending outwardly from the web portion, underlying the edge of the flange of the panel adjacent to it and constituting a seating surface for that flange edge, and attachment clips fastened to the web portions of the retainers, each clip having an arm extending outwardly through a slot in the flange of the adjacent panel, characterized in that each horizontal retainer has a longitudinally continuous drainage trough located within the space bounded by the flange of the corresponding panel to receive water that might otherwise collect in said space or leak toward the building structure, and each vertical retainer has a longitudinally continuous drainage slot serving the drainage trough of each adjacent horizontal retainer, each trough opening to the drainage slot of the adjacent vertical retainer.
Claim 2
Dependent Claim
249 words
An exterior panel wall assembly having a multiplicity of rectangular pan-like panels arranged in closely spaced-apart relation side by side and end to end, each panel having a principal wall forming a portion of an exterior building wall and a continuous peripheral flange extending inwardly from the principal wall toward the building structure, an elongated vertical retainer joined to building structure and located at and coextensive with each vertical flange of each panel and an elongated horizontal retainer joined to the building structure and located at and coextensive with each horizontal flange of each panel, each retainer having a web portion that at least partly overlaps a portion of the flange of each panel adjacent to it and a lateral seating flange portion extending outwardly from the web portion, underlying the edge of the flange of the panel adjacent to it and constituting a seating surface for that flange edge, and attachment clips fastened to the web portions of the retainers, each clip having an arm extending outwardly through a slot in the flange of the adjacent panel, characterized in that each horizontal retainer has a longitudinally continuous drainage trough located within the space bounded by the flange of the corresponding panel to receive water that might otherwise collect in said space or leak toward the building structure, and each vertical retainer has a longitudinally continuous drainage slot serving the drainage trough of each adjacent horizontal retainer, each trough opening to the drainage slot of the adjacent vertical retainer.
Claim 3
Dependent Claim
55 words
A panel assembly according to claim 1 and further characterized in that each drainage trough is constituted by a portion of the horizontal retainer that is generally U-shaped in cross section, joins the flange portion outwardly of the seating surface, with respect to the web portion, and opens toward the principal surface of the panel.
Claim 4
Dependent Claim
71 words
A panel assembly according to claim 1 and further characterized in that each drainage slot is defined by a second flange portion that joins the web portion of the vertical retainer and lies in spaced relation to the rear of the seating flange portion, with respect to the panel, whereby the drainage slot is defined by the seating flange portion, a part of the web portion and the second flange portion.
Claim 5
Dependent Claim
96 words
A panel assembly according to claim 1 and further having a gasket on each seating surface, the gasket being of a low friction material so as not to inhibit substantially movement of the edges of the panel flanges due to thermal expansion and contraction and characterized in that each gasket includes a portion of generally V-shaped cross section lying flatwise on the seating surface of the seating flange, at least the V-shaped portion being resilient and having a leg portion resiliently urged generally flatwise into engagement with the edge of the flange of the corresponding panel.
Claim 6
Dependent Claim
42 words
A panel assembly according to claim 4 and further characterized in that each gasket on each horizontal retainer is oriented with the opening of the "V" facing upwardly so that it tends to catch and direct water toward an adjacent vertical retainer.
Claim 7
Dependent Claim
52 words
A panel assembly according to claim 4 and further characterized in that each gasket on each vertical retainer is oriented with the opening of the "V" facing inwardly with respect to the web portion so that it tends to retain water in the vertical space at the vertical junctures between adjacent panels.
Claim 8
Dependent Claim
89 words
A panel assembly according to claim 1 and further characterized in that the lower end of an array of panels is finished with flashing behind and under the lower portion of each bottom panel, the bottom flange of each bottom panel being spaced-apart from the flashing to allow entry of air for pressure equalization between the exterior and the interior of the panel principal walls and to allow drainage of water, and the lower end of each vertical retainer opening to the flashing to discharge water onto the flashing.
Claim 9
Dependent Claim
41 words
A panel assembly according to claim 7 and further characterized in that the bottom flange of each bottom panel is secured to the building structure against downward movement by clips so that the spacing between it and the flashing is maintained.
