ABSTRACT:
A framework type building panel, having opposed first and second sides, is formed of a plurality of primary and secondary structural members each of which has a web and a flange providing the member with a T-shaped cross-sectional shape; each member also has a series of transverse notches spaced along its web. The panel includes a first series the primary members which are spaced apart and parallel to each other with their flanges defining the first side of the panel, and a second series of the secondary members which are spaced apart and parallel to each other and extend transversely to the primary members and have their flanges defining the second side of the panel, with the webs of the primary members having their transverse notches of their webs engaging areas of opposed webs of the secondary members. The edges of the panel may also be formed by the primary or secondary members, rotated 90.degree. about their axes, so that their webs extend inwardly and engage the ends of the other panel members. The primary and secondary members are preferably differentiated as to their strength.
