Patent ID: 7395999

Claim:
A method for forming a building structure, comprising: placing a mold for a reinforced building panel on a generally horizontally oriented bottom press wall member of a press mechanism having relatively moveable generally horizontally oriented top and bottom press wall members, said mold having top and bottom generally horizontally oriented mold walls defining a rectangular mold cavity and being configured to mold interior and exterior surfaces of said reinforced building panel, said mold having mold edge members configured for molding top bottom and side edges of said reinforced building panel, said top generally horizontally oriented mold wall being removable from said mold; with said top generally horizontally oriented mold wall removed from said mold locating panel reinforcing members and external weather resistant members within said mold cavity; introducing a two-part polyurethane and Portland cement molding medium into said mold cavity in a substantially liquid state, the molding medium establishing intimate contact with said mold walls said panel reinforcing members and said external weather resistant members; closing said mold by assembling said top generally horizontally oriented mold wall to said mold; moving a said top and bottom press wall members toward one another and establishing compressive engagement with said top and bottom mold walls and securing said mold walls against movement during curing of the molding medium to define a hardened and dimensionally stable building panel structure for use as a wall panel or roof panel of a building; after desired hardening of said molding medium causing separating movement of said at least one of said top and bottom press wall members and releasing said compressive engagement of said mold walls; opening the mold by removing said top mold wall member from said mold and removing the hardened, dimensionally stable building panel from the mold cavity; fixing a panel mounting member to outside edge portions of a building foundation at a construction site; and assembling a plurality of said reinforced building panels in side by side relation and with bottom portions thereof located within said panel mounting member and forming walls of a building structure having external weather resistant surfaces defined by said external weather resistant members.
