IMPROVED COMBINATION WOOD AND METAL FLOOR JOIST ABSTRACT Pairs of small dimensioned lumber members are used for the top and bottom chords of a truss member for a floor joist and the like, A zig-zag series of truss strut members are integrally formed with chord connector plates, from a sheet of metal. The connector plates are located at the apexes of the converging struts and have pointed fastening teeth struck out from either side to project into and be embedded into the inner side faces of the pairs of wood members when the wood members are placed in overlapping parallel relation one with another. The joist is assembled in a factory by placing each pair of wood members in parallel spaced apart with the zig-zag web of struts between them and the connector plates sandwiched within the inner side faces of the pairs of wood members, for simultaneous pressing together in a one-step operation to produce a wood-metal laminated joist structure.
