Tensioning Accessories & Force / Displacement Measurement

Tensioning Accessories

For the daily use of our jacks and equipment, we offer accessories that are robust, easy to use and perfectly suitable for on-site use. They are perfectly adapted to individual applications and the equipment used, thus facilitating work and ensuring a fast construction progress.

For clamping the strands easily and safely, our equipment either includes an in-built self-clamping device or a clamping bush that is mounted directly behind the jack. Additionally, the jack can be equipped with a wedging device for actively force-fitting the anchor wedges of strand anchors.

Special stressing chairs ensure an easy positioning of the jacks as well as permanent control of the wedge seating and allowance for tolerances during the tensioning and tying down of the anchors.

When used on bar systems, the anchor nuts can be tightened using a hand ratchet or screwed inside the stressing chair using a driver sleeve.

Force / Displacement Measurement

For monitoring installation, tensioning for performance and proof tests and for the long-term controlling of forces, we offer a comprehensive range of measuring equipment such as analog and digital load cells and length gauges of up to 750mm elongation.

Our special force measuring system DYNA Force® allows an extremely precise readout of the anchor forces in strands and bars. The contact-free measuring is carried out inside the anchor so that no troublesome external devices have to be placed at the anchor head.

Torque Equipment

Anchorage elements and coupler connections can be countered for minimizing slippage in anchorages and threadbar connections and for increasing fatigue resistance. By defined tightening, the GEWl® and GEWl® Plus screw parts are tensioned against each other so that the spliced bars cannot be distinguished from non-spliced bars with regards to stress-strain behavior.

In addition, systems for alternating loads can be developed so deformation resistant by countering that a large number of load changes does not have any influence on the load-bearing behavior of the connections and anchorages.

DSI offers manual torque wrenches and hydraulic impact wrenches that cover the complete force range.

Regular inspections guarantee highest safety standards to eliminate possible risks for the operator and the environment. In our internal workshops, the equipment is regularly maintained, checked and repaired quickly and economically if needed.
