ABSTRACT:
The flat chord truss jig assembly includes a jig pad carrying two pairs of laterally spaced elongated guide bars. Releasable clamps are provided along the opposite outer edges of the pad and engageable with the outermost pair of bars. The innermost pair of bars are connected by longitudinally spaced rods reverse threaded at opposite ends for threaded engagement with the bars whereby rotation of the rods moves the innermost pair of bars toward and away from one another to introduce similar camber in each innermost bar. An end locator plate is positioned between each pair of bars at opposite ends of the truss. The chords and diagonals of a flat chord truss are disposed between the pairs of bars on opposite sides of the jig pad and connector plates of the type having integrally struck teeth are prepositioned at the joints between such chords and diagonals. The jig assembly is moved through a press whereupon the teeth of the connector plates are embedded into the joints to complete a flat chord truss.
