In order to install or tension a brace ( ) having a false bearing, for example a stay cable for a cable-stayed bridge, an external tensioning member or similar comprising a bundle of plastic-sheathed individual elements ( ) made of steel, for example, wires, strands of wires or similar, the individual elements ( ) are exposed in the area of the anchoring in order that they may be anchored at this point in holes ( ) in an anchoring plate ( ) which is supported by the building structure ( ) by means of wedges ( ). In order to ensure that when the strand is anchored the remaining plastic jacket ( ) ends as close as possible to the anchoring plate ( ), it is suggested that the plastic jacket be prevented from making any longitudinal movement during the extension of each individual element ( ) which occurs during tensioning by a stop in the form of an annular shoulder ( ) which surrounds the element ( ) in the anchoring area, and thereby compressed.

Process for the installation and tensioning of a brace having a false bearing, in particular a stay cable for a cable-stayed bridge and anchoring device with which to carry out the process

A guide or deflecting unit for a tension member at a structural component of a structure extending outside of the cross-section of the structure. The tension member extends with a change of direction over a deflection point formed at the structural component. The guide or deflection unit is composed of a tubular shaped piece of a deformable material which surrounds the tension member and whose contour is shaped in the longitudinal direction such that its wall thickness decreases from the middle toward the ends in accordance with the curvature of the required deflection. The predetermined curvature is obtained when tensioning the tension member by the contact thereof with a wall of a straight receiving opening.
