Abstract
A jig system for aligning wooden chords and metal web members in the manufacture of joists, the system includes an assembly surface having a longitudinally extending track therein, and a plurality of jigs positionable in the track. The jigs have upwardly projecting pins for engaging alignment holes in the webs for properly orienting and spacing the webs. The jigs may also have generally parallel alignment bars on either side of the pin for holding the portion of the metal web surrounding the alignment hole therebetween. The jig system can be used in a method of assembling joists which includes the steps of providing web members having a alignment hole at a predetermined height; providing at least one jig having a plurality of pins adapted to engage the alignment holes on the web members; mounting the web members on the jig to vertically align the web members; aligning the top and bottom chords with the aligned web members on the jigs; and pressing the chords and web members together to embed the integral nails on the web members in the top and bottom chords.
