  • Knee brace for glulam and heavy timber construction
    Patent number: 4022537
    Abstract: A knee brace to provide lateral resistance at the bottom of glued laminated beams and solid heavy timbers. The brace consists of an elongated strap connected at its mid point to the bottom of the glulam or heavy timber. Legs angled outwardly are connected at their ends to transverse members. Special cut sections in the strap provide tabs running perpendicular to the bottom of the braced glulam or timber. The tabs are held to the side faces of the braced member by nails. The bent tabs and nails in the bottom of the glulam provide the resistance to overturn loads.
