Abstract
A reinforced construction panel which is bent around a longitudinal flexure axis. The panel has a plurality of parallel, dovetail-shaped grooves in its inner surface. Each of the dovetail-shaped grooves lies in a plane which is perpendicular to the longitudinal flexure axis. A number of tension elements, each one of which is disposed in a plane which is perpendicular to the longitudinal flexure axis, end in two male fittings, one at either end. Each of the male fittings is sized and shaped so as to be received and held in one of the parallel, dovetail-shaped grooves.
