Abstract
A tie anchor for strip-type tension members includes an anchor body disposed on at least one side of the tension member. The anchor body includes a plurality of clamping blocks arranged at a distance from each other in a longitudinal direction of the tension member. The clamping blocks are connected to tension member by adhesive and/or friction (clamping friction). An end-most (final) one of the clamping blocks is attached to a fixed abutment. Adjacent clamping blocks are interconnected by expansion members whose spring stiffness becomes progressively stronger toward the end-most clamping block.
Claims16
A tie anchor for tension members, the tension member comprising a strip having opposing sides, the tie anchor comprising an anchor body disposed on at least one of the strip sides and including at least first, second, and third clamping blocks arranged at a distance from one another in a longitudinal direction of the strip, the clamping blocks connected to the one strip side by at least one of:
- adhesive and friction;
- wherein the first clamping block constitutes a last clamping block disposed at an anchoring end of the tension member and is adapted to be supported on a fixed abutment, wherein the second and third clamping blocks are interconnected by a first extension section having a first spring stiffness, and the first and second clamping blocks are interconnected by a second extension section having a second spring stiffness greater than the first spring stiffness.
A building structure including a fixed abutment, a tension member comprising a strip having opposite sides, and a tie anchor interconnecting the strip and the fixed abutment;
- the tie anchor comprising an anchor body disposed on at least one of the strip sides, and including a plurality of clamping blocks arranged at a distance from each other in a longitudinal direction of the strip;
- the clamping blocks being connected to the one strip side by at least one of:
- adhesive and friction;
- wherein an end-most clamping block is secured to the fixed abutment;
- adjacent clamping blocks being interconnected by expansion sections, each expansion section defining a spring stiffness, wherein the respective spring stiffnesses become progressively stronger toward the end-most clamping block.
