Abstract
The panel includes a square base of expanded polystyrene, and has two projecting sides which mate with the undercut sides of two identical adjacent panels. All four sides of the base are bevelled slightly, and the front face defines intersecting grooves so that a polymer fortified concrete facing can be applied to the front of the base without warping the base as the concrete shrinks during hardening. An acrylic binder, with quartz granules carried thereon is provided over the concrete facing to enhance the appearance of the panel, and to improve its resistance to impact.
Claims13
An exterior wall panel adapted for assembly with other similar panels, and comprising a base of heat insulating material, said base having a generally regular polygonal configuration and having at least one side defining a projecting edge adapted to mate with a cavity defined in the adjacent side of an identical adjacent panel, said base having a rear face adapted for attachment to a structure or the like, and having a front face defining grooves oriented generally perpendicularly with respect to said projecting edge, and a polymer fortified cementitious facing on said front face of said base, said facing having a thickness in the range of 1/8to 1/2 inch, said facing including rearwardly projecting ribs integrally formed in the facing which ribs fill said grooves in the base to a depth at least as great as that of said facing thickness, and a layer of polymer material adhered to the facing, said front face of said base has a bevelled edge, and wherein said facing also includes a bevelled edge such that an overhanging portion of the facing projects inwardly thereof to further reinforce the base.
An exterior wall panel adapted for assembly with other similar panels, and comprising a base of heat insulating material said base having a generally regular polygonal configuration and having at least one side defining a projecting edge adapted to mate with a cavity defined in the adjacent side of an identical adjacent panel, said base having a rear face adapted for attachment to a structure or the like, and having a front face defining grooves oriented generally perpendicularly with respect to said projecting edge, and a polymer fortified cementitious facing on said front face of said base, said facing having a thickness in the range of 1/8 to 1/2inch, said facing including rearwardly projecting ribs integrally formed in the facing which ribs fill said grooves in the base to a depth at least as great as that of said facing thickness, and a layer of binder material adhered to the facing, and granules entrained in said layer.
An exterior wall panel adapted for assembly with other similar panels, and comprising a base of heat insulating material, said base having a generally regular polygonal configuration and having at least one side defining a projecting edge adapted to mate with a cavity defined in the adjacent side of an identical adjacent panel, said base having a rear face adapted for attachment to a structure or the like, and having a front face defining grooves oriented generally perpendicularly with respect to said projecting edge, and a polymer fortified cementitious facing on said front face of said base, said facing having a thickness in the range of 1/8 to 1/2 inch, said facing including rearwardly projecting ribs integrally formed in the facing which ribs fill said grooves in the base to a depth at least as great as that of said facing thickness, said front face of said base has a bevelled edge, and wherein said facing also facing projects inwardly thereof to further reinforce the base and said bevelled edge including a concave or grooved portion, said bevelled edge of said facing being of complementary convex cross section.
