Astra Turm, Hamburg, Germany
An Ancon Tension System has been used to support a concrete ring weighing over 500 tonnes, which in turn is suspended above an 80 metre high office block.
Ancon Germany offered significant design assistance and supplied a 42mm Ancon Tension Bar System.
The project is now complete and the tower has become one of Hamburg's landmark buildings, with the suspended ring as its distinctive feature.
Tie bars are increasingly being used in structures and buildings as an architectural as well as a structural element.
Successfully re-engineered by Ancon, the IHR range of internal head restraints can now accommodate gaps at the wall head of up to 75mm, extending the previous maximum of 50mm.
Ancon has been honoured at a Royal reception to celebrate its success in the 2018 Queen’s Awards for Enterprise – the third Queen’s Award for the company.
