A New Approach for Automated Design and Robot-Assisted Production of Structurally Optimised Reusable Concrete Building Elements
Concrete, the most used construction material worldwide, currently lacks realistic alternatives in terms of performance and availability. Industrialisation resulted in the reduction of price, especially in developed countries, with 1m³ of concrete equivalent to only approximately 1.25 hours of skilled labour in Europe. As a result, the relevance of optimizing the material use diminished, leading to an underutilization of the mechanical properties and consequently, a high environmental impact. Moreover, the current inefficient production approaches hinder its potential for efficient use of the material itself. This contribution presents a new automated design and production approach with focus on increasing the resource efficiency within concrete prefabrication. The design concept represents an automated topology optimisation with a strut-and-tie model running in the background. The production approach is based on a modular assembly concept realised by robot production islands, which can be used individually or in groups either in a prefabrication plant or for on-site production. The backbone is a new automated shuttering concept which is open for different concrete mixtures and therefore also for further developments on material side. This, combined with the development of a modular component kit, allowing for a reuse of the elements, offers the industry the possibility of a higher value circular economy. Within the presentation the concept is introduced alongside first preliminary experiments and an outlook on further planned research demand.
