PROCESS FOR THE INSTALLATION AND TENSIONING OF A BRACE HAVING A FALSE BEARING IN PARTICULAR A STAY CABLE FOR A CABLE-STAYED BRIDGE AND AN ANCHORING DEVICE WITH WHICH TO CARRY OUT THE PROCESS

摘要

PURPOSE: A process for installing and tensioning of brace having false bearing is provided to find a simpler and less costly method of removing the PE jacket in the area of the tensioned end or of exposing the strand in this area in such a manner that, in its final state, the remaining PE jacket ends as close as possible to the area in which the strand is anchored. CONSTITUTION: In order to install or tension a brace(1) 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(2) made of steel, for example, wires, strands of wires or similar, the individual elements(2) are exposed in the area of the anchoring in order that they may be anchored at this point in holes(6) in an anchoring plate(7) which is supported by the building structure(9) by means of wedges(5). In order to ensure that when the strand is anchored the remaining plastic jacket(4) ends as close as possible to the anchoring plate(7), it is suggested that the plastic jacket be prevented from making any longitudinal movement during the extension of each individual element(2) which occurs during tensioning by a stop in the form of an annular shoulder which surrounds the elements(2) in the anchoring area, and thereby compressed.
