Ja, wirklich: Mecklenburg Vorpommern ist die Avantgarde im experimentellen Strohballenbau in Deutschland. Im kleinen Wangelin, bekannt durch den gleichnamigen und bezaubernden Garten, entsteht derzeit der erste selbsttragende Tonnengewölbebau aus Strohballen. Die 5 Tonnengewölbe werden von einer buntgemischten und sehr engagierten Crew aus Strohballen-, Lehmbauern und Workshopteilnehmern errichtet.
Auch die regionalen Handwerker haben sich an diesem Projekt beteiligt. Der Zimmermann Michael Rückert hat bewegliche Innenschalungen gebaut, die genau die Wölbung der Tonnen vorgibt. Die Maurer von Febe-Bau hatten die Abschlussbögen an der Südfassade und die Nordwand bereits erstellt. Interessant daran ist, dass der Porenbeton direkt aus der Region kommt und nur einen Weg von 15 km hinter sich hat.
Das ganze Gebäude erinnert an orientalische Lehmtonnengewölbe, denen Professor Gernot Minke, der Workshopleiter, seine Inspiration verdankt. Prof. Minke ist für seine Low Budget Experimentalbauten mit Lehm bekannt. Er untersuchte, warum runde Formen wie die Kuppel oder Tonne in orientalischen Ländern Erdbeben besser trotzen, als manch in Beton gegossenem modernem Bau. Doch seine Neugier trieb ihn weiter und er kombinierte die runde Lehmarchitektur mit der Idee der perfekten Dämmung durch Strohballen. Das ganze basiert auf Forschungen, die er zum Thema lasttragender Strohballenbau an der Universität Kassel geleitet hatte. Diese Forschung hat er in verschiedenen Gebäuden umgesetzt. Doch hier in Wangelin werden nun die ersten offiziell genehmigten lasttragenden Tonnengewölbe aus Strohballen in Deutschland umgesetzt.
Believe it or not, Mecklenburg-Vorpommern is upfront when it comes to experimental straw-bale construction in Germany.At present, the first self-supporting barrel-vault construction made of straw-bales is being built in the small village of Wangelin, known for the enchanting garden of the same name.The five barrel vaults concerned are to be erected by a varied and very dedicated crew of straw-bale and earth builders as well as workshop participants.
The regional workmen also have contributed to this project.The carpenter Michael Rückert has built movable internal formworks providing the exact curvature of the vault.The bricklayers of Febe‑Bau Company have already finished the final arches of the south façade as well as the north wall.Note that the aerated concrete used is a regional product and has travelled less than 15 km.
The entire building is a reminder of Middle Eastern mudbrick or adobe barrel vaults, which, indeed, served the workshop leader Prof. Gernot Minke as an inspiration.The professor is known for his low-budget experimental mudbrick buildings.He has studied the reasons for rounded forms, such as the dome or barrel-vault as used in the Middle East, to withstand seismic loads better than many a modern building cast in concrete.But his curiosity drove him further still and he started combining rounded mudbrick constructions with the idea of the perfect insulation enabled by using bales of straw.This is based on research on load-bearing straw-bale constructions which he conducted at the University of Kassel.The results have been implemented in various buildings, but Germany’s first officially approved load-bearing barrel vault made of straw bales is about to be realized here in Wangelin.
