Description

The Katharinenkreisel, one of Frankfurt’s most picturesque areas, is home to one of the latest examples of cutting-edge high-rise architecture in the financial hub. Completed in the summer of 2015, the “St Martin Tower” multi-storey building complex comprises 26,000 square metres of lettable floor space over 18 levels and an adjacent seven-floor building. The office block complies with today’s most stringent efficiency standards for energy and floor space and boasts flexible office space that attracts both small businesses and multinational corporations. The developer Hansa AG dedicated the building to St Martin of Tours, and therefore included day-care centres for children and numerous meeting spaces for community events alongside the offices.

The sophisticated design of the building is exemplified in the nine glass lifts by KONE GmbH. The 67m-high lift shafts can carry up to 26 passengers at a speed of 2.5 metres per second and are fitted with JORDAHL® anchor channels and clevises for safety. As high load-bearing components, JORDAHL products guarantee the secure fastening of the steel construction so that each elevator car is controlled in conjunction with a counterbalance. Anchor channels were also used to connect the glass façades; the Berlin-based JORDAHL GmbH supplied the Frankfurt project with hot-rolled anchor channels JTA W 40/22 and JTA W 50/30 in sizes from 250 millimetres to 1800 millimetres. JORDAHL® punching shear reinforcement JDAs were also fitted to transfer high transverse forces into the flat floor structures.

The “just-in-time” principle was used for the construction process, meaning that JORDAHL delivered the required materials just as they were needed.
