Abstract
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.

Claim 1
Independent Claim
135 words
A knee brace for connecting timbers or glulam beams to a transverse member or members comprising: a. an elongated metal strap having ends adapted for connection to said transverse member; b. said strap being formed with right angle twists so that said ends are in face to face contact with said transverse member; c. a center portion adapted for connection to the underside surface of said glulam beam; and d. bend tab members adapted for connection to the sides of said glulam beam and formed from said strap member adjacent to and on both sides of said center portion by cutting portions of said strap along its longitudinal side and transversely to one edge forming a pair of bendable tabs adapted for bending at a right angle about the lower edges of said glulam beam.
