Non-sequentially installed dry joint wall panel system
View Patent ↗A wall panel system for attachment to a building surface includes a plurality of generally vertical supports, and a plurality of generally horizontal mounting rails interconnected with the vertical supports to define a panel mounting gridwork. The horizontal mounting rails have an upper mounting feature and a lower mounting feature, on a side opposite from the building surface. A plurality of panels each have a rear surface, an upper extrusion mounted to a top of the rear surface, and a lower extrusion mounted to a bottom of the rear surface. The upper extrusion mates with a corresponding lower mounting feature on the gridwork, and the lower extrusion mates with a corresponding upper mounting feature on the gridwork. The plurality of panels have a gap about a periphery thereof relative to any adjacent panels, whereby the panels can be non-sequentially mounted to the gridwork.
1. A wall panel system for attachment to a building surface, said wall panel system comprising:
a plurality of generally vertical supports;
a plurality of generally horizontal mounting rails interconnected with said vertical supports to define a panel mounting gridwork, said horizontal mounting rails having an upper mounting feature and a lower mounting feature on a side opposite from the building surface; and
a plurality of panels, each said panel having a rear surface, an upper extrusion mounted to a top of said rear surface, and a lower extrusion mounted to a bottom of said rear surface, said upper extrusion mating with a corresponding lower mounting feature on said gridwork, and said lower extrusion mating with a corresponding upper mounting feature on said gridwork, said plurality of panels having a gap about a periphery thereof relative to any adjacent panels, whereby said panels can be non-sequentially mounted to said gridwork, each said panel including an outer surface opposed to said rear surface and a top return flange and a bottom return flange that both extend at an approximate 90° angle relative to said outer surface, said top return flange extending farther than said bottom return flange.
2. The wall panel system of claim 1 , wherein each of said upper mounting feature and said lower mounting feature include a recess, and wherein each of said upper extrusion and said lower extrusion include a projection which mates within a corresponding recess.
3. The wall panel system of claim 2 , wherein each of said upper extrusion and said lower extrusion are identical.
4. The wall panel system of claim 1 , wherein each said panel includes a pair of side extrusions mounted to respective side edges of said rear surface.
5. The wall panel system of claim 4 , wherein said upper extrusion, said lower extrusion and said pair of side extrusions are substantially identical.
6. The wall panel system of claim 1 , wherein said panels may be mounted to said gridwork without the use of tools.
7. The wall panel system of claim 1 , wherein each said mounting rail includes a first extrusion attached to the building surface and a second extrusion connected to said first extrusion.
8. The wall panel system of claim 7 , wherein said first extrusion includes a standoff that abuts the building surface.
9. The wall panel system of claim 7 , wherein said upper mounting feature and said lower mounting feature are a part of said second extrusion.
10. The wall panel system of claim 1 , wherein said top return flange includes a vertical extension plate that extends upward.
11. The wall panel system of claim 10 , wherein said vertical extension plate curves behind a bottom return flange of an adjacent panel but does not contact the rear surface of said adjacent panel.
12. A method of building a wall panel system on a panel mounting gridwork including a plurality of mounting rails, each said mounting rail including a lower mounting feature and an upper mounting feature, including the steps of:
providing a plurality of panels, each said panel having a rear surface, an upper extrusion mounted to a top of said rear surface, a lower extrusion mounted to a bottom of said rear surface, an outer surface opposed to said rear surface, and a top return flange and a bottom return flange that both extend at an approximate 90° angle relative to said outer surface, said top return flange extending farther than said bottom return flange;
mounting a first panel to a first mounting rail and a second mounting rail adjacent to said first mounting rail on said gridwork; and
mounting a second panel to said second mounting rail such that a gap is formed between said first panel and said second panel, wherein said mounting steps can be performed non-sequentially.
13. The method according to claim 12 , wherein said mounting of said first panel is performed by mating an upper extrusion of said first panel with a corresponding lower mounting feature of said first mounting rail and mating a lower extrusion of said first panel with a corresponding upper mounting feature of said second mounting rail.
14. The method according to claim 12 , wherein said mounting of said second panel is performed by mating an upper extrusion of said second panel with a corresponding lower mounting feature of said second mounting rail and mating a lower extrusion of said second panel with a corresponding upper mounting feature of a third mounting rail adjacent to said second mounting rail.
15. The method according to claim 12 , wherein each of said upper extrusions and said lower extrusions are identical.
