Tool-Development for Pre-Cast Concrete Elements in Robot-Assisted Flow-Production (2024-10)¶

Future-oriented flow production depends on consistent digitally controlled tool systems in the digital replica network. Concrete spray extrusion, for example, can be used to create facade modules consisting ofa thin layer ofshotcrete and rib-shaped supporting structures with high strength and excellent surface qualities. The newly developed combined nozzle offers the ability to both spray and extrude, adapting to mortar and concrete. Furthermore, flow production includes the automated integration of anchors for attaching facade modules to buildings, for which special anchor and tool systems have been developed. The measured values from the tests demonstrate the feasibility and increase in productivity. The creation of a digital replica (Industry 4.0) was based on the generated data and parameters. The resultant increase in productivity has positive economic effects. The use of lightweight structures enables the series implementation of modular constructions.
