Abstract
In an anchored tension member individual elements, such as steel rods or the like, extend between a pair of anchoring discs each of which is secured on a support. One support is spaced horizontally and vertically from the other so that the tension member extends at an acute angle to the horizontal. In assembling and installing the tension member, first one individual element is placed through a tubular casing resting on the support of a support structure which incorporates one of the supports. Next, the individual element is tensioned between and anchored to the anchoring discs. During this operation, the tubular casing is lifted off the surface and extends rectilinearly between and is spaced from both of the anchoring discs. In turn, the remaining individual elements are placed through the tubular casing, tensioned and then anchored to the anchoring discs. As a result, the tension member can be installed in position without additional auxiliary apparatus, such as lifting devices and scaffolds.
