Abstract

Abstract WOOD AND METAL BUILDING COMPONENT ADAPTED FOR PREFABRICATED MANUFACTURE ABSTRACT The following specification discloses a prefabricated building component for use as a rafter, stud or joist and comprises the following elements; a first wooden member of rectangular cross section has a pair of planar side faces aligned in planar relationship with a pair of planar side faces of a second wooden chord member of rectangular cross section. A first sheet steel web plate is spaced between said chord members and partially overlies one of the side faces of the first wooden member and partially overlies the adjacent side face of the second wooden member. A second sheet steel web plate partially overlies the adjacent side faces of the other side of the aligned chord members. Gang nail means are struck out perpedicularly from one side of each of the web plates to face the portions of the chords overlain by the web plates and are driven into the wooden chords simul-taneously while the webs and chords are held in a jig thereby connecting the elements together to form the novel product herein.
