ABSTRACT:
A one-piece structural member with integral fastener prongs for joining to a separate penetrable plate such as plywood or the like. The structural member is formed with at least one web section and with at least one continuous perpendicular flange section having the fastener prongs formed therein. The continuous flange section with the integral web section permits a large variety of prong sizes, spacings and structural configurations to be obtained thereby producing a large variety of panel and beam stiffness and span lengths. The method disclosed herein permits the construction of novel composite structural panels and beams at a job site using the one-piece structural member which is pressed together with a penetrable plate such as plywood, wood studs or the like by means of a pair of pressure rollers, a press brake or other means. The plate functions as an extended flange in a composite section with the web of the structural member taking the shear stresses and the plate taking most of the bending stresses as well as performing a sheathing function. The plates may be spliced together longitudinally to form shallow long-span stressed skin panels and transversely to develop diaphragm action to resist high wind and seismic loading.
