Post-trimable pre/tensioned stressed architectural member

A prestressed post-tensioned type architectural structural member, serving as a beam, column, and the like, and generally of elongated formation having a rectangular cross-sectional shape comprising opposing upper and lower surfaces and longitudinally opposed ends featuring improved positioning of truss-element terminuses so as to facilitate pre-installation trimming convenience;

• comprising:
• a fabricated multi-ply vertically permanent laminated construction, including at least one longitudinally arranged drape-deflected post-tensionable truss-element set at a desired linear deflection angle from said upper surface into a provisional retaining channel made therein at least one of said vertical laminations, thereby serving to substantially conceal said truss-element except for said opposed terminuses which emerge near the opposed beam ends in local relief notches atop the beam's said rectangular cross-section;
• and including longitudinally opposed end coupling fixture means by which to securely tighten said truss-element in a prestressed manner.
