Abstract:
A reinforcement tie rod for restraining relative movement between a pair of opposed walls of a ventilating duct, said walls being provided with a pair of opposed perpendicularly aligned holes therethrough, said reinforcement tie rod comprising;a. an elongated rod having opposed longitudinal ends adapted to be received through respective ones of said perpendicularly aligned holes provided through said duct walls and protrude outwardly therefrom,b. a pair of abutment structures fastened to said respective opposite longitudinal end portions of said rod, each of said abutment structures having a flange including an outer transverse flange wall adapted to abut an inner wall surface of one of said opposed duct walls, the spacing between said outer transverse surfaces of said flange walls approximating that of said perpendicular spacing between said duct walls, said abutment structure including a tubular portion located longitudinally inwardly of said flange, said tubular portion having a bore which extends through said flange and receives therethrough said rod, andc. a pair of external fasteners, a separate one of which is adapted to be fastened onto a separate one of said opposed rod ends protruding through said duct wall holes, said fastener being adapted to exert a longitudinally inwardly directed force against an outer wall surface of said duct wall to thereby press said duct wall against said flange wall of said abutment structure.
