  • Wooden I-beam
    Patent number: 4191000
    Abstract: A wooden I-beam suitable for use as a joist or a rafter, comprising solid wooden flange members of rectangular cross section joined to opposite sides of a plywood web member by an adhesively fastened joint. Large joint contact surface area, and a small amount of wood removal from flange members to form the joint, cooperate to create a strong joint without unnecessary weakening of the flange members, thus producing wooden I-beam members of consistently high strength.
