Abstract:
Non‐Waste‐Wax Formwork for customized precast concrete construction – Practical example of the digital manufacturing process for small series of large‐format bollards At the Institute for Structural Design, ITE, fundamental research work has been carried out to develop the non‐waste wax formwork technology, which minimizes formwork waste in the production of freely formed concrete components. This is intended to meet the needs of the precast concrete component industry for technologies to reduce production waste and build low‐emission production lines. The current Eurostars‐funded research project “Robocrete” at ITE together with ODICO Construction Roboctics, Odense, Denmark, and BNB, Beton und Naturstein Babelsberg, is investigating, among other things, processes for the production of large‐format wax block blanks for industrial integration into production lines for small series. The aim is to combine the research results in a digitalized robotic production unit for wax formwork for concrete casting. In previous research, it was not possible to efficiently produce crack‐ and stress‐free wax blocks with a volume of more than 1 m 3 . For this purpose, optimized methods for the production of wax block are being researched and developed further into a fully digital manufacturing process. In a case study under real conditions of the precast concrete industry with the company Rinn, the wax formwork technology for casting of a geometrically complex concrete bollard 1.2 t of weight was successfully tested.
