Neuer Kanzlerplatz

Bonn , Germany

A fascinating ensemble of buildings called "Neuer Kanzlerplatz" is currently under construction on the site of the former Bonn Center. The three buildings, one of them a high-rise with a height of 101.5 m and 28 floors, will inspire the future working world with their aesthetics and to serve as a meeting place.

The design of the building's facade is striking - a protruding facade provides a distinctive look at the New Chancellor Square. A load-bearing structure made of white architectural concrete and refined exposed surfaces form the characteristic facade elements. In addition, high-quality graffiti protection was applied to all components in the precast plant for a long-lasting appearance. Construction of the urban quarter is scheduled for completion in 2022 and is expected to provide over 66,000 sqm of office space.

Load-bearing facade with Egcobox®

The special structural feature of the administration buildings is the load-bearing facade. Precast concrete elements were used for this and connected to the floor slabs in each case. The mullion-transom construction of the facade elements was previously concreted in one piece in the precast plant. For the thermal separation of the cold, prefabricated facade and the warm floor slab, the cantilever connection Egcobox® from MAX FRANK was used with the elements. This allows thermal bridges to be reduced, and condensation and associated mold growth to be reduced. The high requirements for horizontal and vertical shear load bearing capacity could also be met with the use of Egocobox®. A highly reinforced edge beam ensured that these forces were transferred to the floor slab.

Product combination for low transport volume and individuality

In order to reduce the transport volume of the façade elements from the precast plant to the construction site in Bonn, the shear force bars of the Egcobox® were shortened by means of MAX FRANK Coupler screw connections. The installation of the corresponding counterpart of the MAX FRANK Coupler screw connection was carried out on site. The product combination of the Egcobox® thermal separation unit and the MAX FRANK Coupler screw connection is credible due to its low transport volume and individuality.
