Abstract
A pre-stressed construction element is set forth which includes a rigid member adapted to span longitudinally between upright supports and to define a load bearing construction element. At least one tendon extends longitudinally along the member and is connected at or adjacent the ends of the member. To pre-stress the member, each tendon is tensioned resulting in a pre-stressing compressive force to be imposed on the member at its ends. Pre-stressing enhances the load bearing characteristics of the member. To impose lateral pre-stress forces on the member supports may be provided. One or several tendons engage are deflected by and underlie the support. When the tendon is tensioned, a force is imposed upon the support and thereby the member.
