ABSTRACT:
This invention provides an improvement related to the well known prestressed-concrete structural member, such as is commonly employed by the construction industry to achieve greater load-supporting ability for beams, columns and the like. Presently, laminated wooden-beams for example, are being mass-produced which exhibit a substantially increased load-bearing ability over an equivalent non-laminated beam. However, the physical dimensions and weight encountered in some applications can not only impose severe architectural design comprises, owing to beam-thickness to walk-under clearance; but often, requirement for special heavy-duty handling equipment at the site as well, owning to their inherent weight/mass. This invention serves not only to reduce the preceding problems, but to reduce problematical installation guess-work by enabling the builder to conveniently trim the beams ends to fit exact site installation spans, spans -without effecting the pretensioned integral truss-element.
