Abstract
The present invention relates to a lightweight reinforced beam which utilizes a tendon system to provide tension on a rigid panel structural frame made from wood, wood composite, plastic or other material. An alternative embodiment uses a tendon system to provide tension on a precast form made from a castable material such as concrete by post tensioning a shielded tendon. This tendon, made from steel, carbon fiber or similar materials, will resist a load imposed on the reinforced beam and will support a large load relative to the weight of the tendon. Such a configuration would reduce the manpower and equipment necessary for placement and handling and transporting of such a beam, be easy and inexpensive to manufacture from a variety of materials and in a variety of lengths and sizes so as to be useful in a number of different load bearing situations, allow for post-tensioning of a shielded tendon thus shortening the length of time required for manufacture of the structure, and which would bear an equal or greater load than conventional solid beams at the point of greatest load demand thus providing for a safe, economical alternative to conventional solid beams for construction purposes.
