Product: Precast concrete parts
Product category: Constructions
For structural reasons, only concrete was used. The precast concrete elements for the ceiling strips on the west side and for the balconies and the cantilevered roof on the east side were designed to appear as filigree and slender as possible. In addition, to avoid thermal bridges, these prefabricated elements had to be designed in such a way that they could be installed in front of the load-bearing structure of the building using specially-developed Schöck Isokorb load-bearing thermal insulation elements. Ultimately, 80 different constructions were used, which were developed and tendered by the structural engineer. All the loads of the balconies as well as those of the ceilings at the top of the building are carried far into the building. In order to ensure water drainage, the precast concrete elements for the balconies were designed with slopes and drip lips. All the elements were produced by Siegl Fertigteile und Beton. The largest elements for the balconies and roof on the east side and the ceiling strips on the west side were 4 to 5 m long.
