For the thermal decoupling of the balcony slabs, over 1,650 Egcobox® thermally insulating cantilever connectors have been installed in the SKY construction project.
The first ten storeys are designed for exclusive business use while the upper eight storeys, with unique views, are reserved for residential use.
The Egcobox® thermally insulating cantilever connector from MAX FRANK is one of the most extensively used components in the building shell; more than 1,650 units over 16 floors. The product will be used on site for the thermal decoupling of the balcony slabs. The Egcobox® is designed to minimize thermal bridges, based on the static requirements of the loads on the balcony slab.
The individual adaptability of the Egcobox® has already allowed great flexibility in the planning of the SKY project. With cantilever lengths of the wrap-around balconies varying from 1 to 4 meters, the static requirements for the balcony connection are very high and require centred introduction in some cases.
In order to ensure a smooth and efficient workflow, it was necessary to coordinate in detail the Egcobox® reinforcement layout with the ceiling, especially in the highly-reinforced corner areas, and the column structure. In addition to the standard length of 1,000 mm, custom lengths of 300, 500 and 900 mm also contributed to the optimization of the balcony slab connection. Cutting of elements to metric lengths on site was thus eliminated.
Delivery of additional MAX FRANK formwork technology products rounded off the successful "SKY" project.
