prestressed element and anchoring of the spanngliedes and processes for the manufacture of anchor

摘要

The invention relates to a tensioning mechanism, comprising at least one tensioning element (1) which is surrounded by a protective covering (2). The tensioning (1) element has a rectangular or square cross-section so that it is possible to achieve a high pretensioning force with a small clamping element cross-section. An anchoring wedge (7) is provided for anchoring the inventive tensioning mechanism in an anchoring body. Said anchoring wedge is configured with a plane surface on the surface facing towards the tensioning mechanism (1) or tensioning elements.
