Established systems for the thermal separation of concrete balconies require the structure to be grouted and necessitate support and formwork structures during the hardening period. This results in poor recyclability at the end of the balcony's service life, as well as increased time and cost during manufacture. The balcony connection presented here shows a way in which prefabricated balconies can be permanently fixed in future without grouting and completely without support and formwork structures. At the same time, the structure presented enables high-quality recycling of the building materials used and reuse of complete components.
