Title:
Abstract:	Infraleichtbeton (ILC) erlaubt mehrgeschossige Wohnungsbauten aus großformatigen Fertigteilen, weil er fester ist als andere Dämmbetone. Da der Werkstoff gleichzeitig trägt und dämmt, entfallen komplizierte (bau-)konstruktive Schnittstellen. Er bietet somit eine monolithische Alternative zum Bauen mit Wärmedämmverbundsystemen (WDVS). Großformatige Elemente aus diesem Werkstoff haben den Vorteil, dass der Fugenanteil minimiert werden kann, wodurch die Kosten für Fügung und Montage reduziert werden. Im Folgenden wird das Konzept des DBU-geförderten Forschungsprojekts ILVO (Vorfabrikation von Fertigteilen aus Infraleichtbeton) vorgestellt. Der Bezug zur Geschichte des Bauens mit vorgefertigten Elementen aus Beton der 1960er-Jahre wird erörtert. Vorbilder bzw. Referenzen, welche die Bearbeitung der Varianten begleitet haben, werden erläutert. Für jede Variante werden ein historisches Referenzprojekt, das Konzept, das Element und die Konstruktion erklärt. Constructing with large components of infra-lightweight concrete (ILC) - three constructive design options for multi-story housing In contrast to other insulating concretes, due to its strength, it is possible to build multi-story housing with Infra-Lightweight Concrete (ILC). Since the material simultaneously supports and insulates, complicated (structural) design interfaces are eliminated. It thus offers a monolithic alternative to building with external thermal insulation composite systems. Large components made of this material have the advantage that the proportion of joints can be minimized, which reduces the costs of joining and assembly. In the following the DBU funded project ILVO (prefabrication of large components of ILC) is introduced, and the developed concept explained. A connection to the history of building with prefabricated elements of concrete in the 1960s is drawn - role models and references that have accompanied the development of variations, are introduced. For every variation a historic reference, the concept, the element, and the construction are explained.
