GRID-LIKE BUILDING PANEL FRAMEWORK

A framework type building panel having opposed first and second sides is formed of primary and secondary structural members, each primary member having a web and a flange connected to form a T-shaped cross-section, and each secondary member being a flat board having parallel side surfaces. The panel includes a first series of the primary members which are parallel to each other with their flanges defining the first side of the panel, and a second series of the secondary members which extend transversely to the primary members and have outer side surfaces defining the second side of the panel, the primary members having their web outer edges attached to inner overlying surfaces of the secondary members. The panel further includes two additional flat boards forming the opposite ends of said panel and each connected to aligned ends of said primary members.
