Abstract
Abstract Wood trusses used in building construction which have reinforced chord members. The reinforcing is made of sheet metal steel strips which have nail-like teeth punched from their surface, which are pressed into the wood chord members along their entire length. The steel strips overrun the length of the truss slightly and the ends are used as a tie down means. The continuous steel strips may also be used as connector plates to attach the chords to the truss webbing. The steel strips also serve to hold the trusses in a pre-cambered position.
