초록 ▼

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.

대표청구항 ▼

In a structural fastener/stiffener member having two oppositely positioned bearing point ends and a mid-point center of the member between the two opposite ends, with the space between being divided into three areas on each side of the midpoint center and with the areas being called the end one-third, the next one-third and the center one-third of the flange section, the fastener/stiffener member being designed for use with a separate penetrable plate which is fastened to the member and is rigidly held thereto by fastener/stiffener prongs with the member and the fastened penetrable plate forming a composite structural unit that may be used as a structural beam which rests on the bearing point ends and is capable of accepting increased downward forces that cause bending to occur in a beam, the improvement comprising: (a) the member being formed with at least one elongated web section and with at least one continuous elongated perpendicular flange section; (b) the flange section having formed thereon a predetermined total number of integral fastener/stiffener prongs protruding from the continuous flange section; and (c) over 50% of the total number of fastener/stiffener prongs in the flange section are formed near the two oppositely positioned bearing point ends in the end one-third of the continuous flange section closest to each bearing point end.
