BUILDING PANEL ASSEMBLIES AND METHODS OF USE IN WALL STRUCTURES

摘要

Light weight fiber-reinforced polymeric (FRP) structural building panels and panel assemblies, sized and configured for construction of non-portable wall structures permanently fixed to the ground. Fibers in the panel are typically oriented within 15 degrees of a top-to-bottom, e.g. axial, direction in the panel providing, in part, enhanced top-to-bottom crush strength of a panel/wall. The panels typically have a bias to deflect toward the surface of the panel which faces outwardly of the building, toward the backfill soil which faces the panel on the outside the building. Panels of the invention typically have mass of no more than 18 pounds per foot height per linear foot length of the building panel, and vertical crush resistance capacity of at least 2000 pounds per linear foot length of the building panel, using a safety factor of 3.

主权项

1. A fiber-reinforced polymeric load-bearing building panel having a length, a top and a bottom, and comprising:
(a) an outer fiber-reinforced polymeric layer about 0.10 inch thick to about 0.30 inch thick, said outer layer comprising a first set of continuous fibers in a first reaction-cured resin composition, said outer layer defining a first outermost surface of said building panel; (b) an inner fiber-reinforced polymeric layer about 0.10 inch thick to about 0.30 inch thick, said inner layer comprising a second set of continuous fibers in a second reaction-cured resin composition, said inner layer defining a second outermost surface of said building panel; and (c) a plurality of load-bearing studs, spaced along the length of said building panel and extending, from said inner layer, away from the second outermost surface to end panels (130) of said studs, including away from said building panel, said studs extending along the height of said building panel, and having walls, defining outer surfaces of said studs, about 0.10 inch thick to about 0.30 inch thick, said walls of said studs comprising a third set of continuous fibers in a third reaction-cured resin composition,said building panel having a thickness between said inner layer and said outer layer, excluding any dimensions of said studs, of about 2 inches to about 5 inches,said building panel having a mass of no more than 18 pounds per foot of height per linear foot length of said building panel, and a vertical crush resistance capacity of at least 2000 pounds per linear foot length of said building panel when tested according to ASTM E72, and using a safety factor of 3.
