Robotically Placed Reinforcement Using the Automated Screwing Device – An Application Perspective for 3D Concrete Printing

Abstract

In structural applications reinforcement is required to achieve sufficient tensile strength and ductility. While several concepts are being developed to achieve this in 3D concrete printing, no generic method has been established yet and as a result all built objects are solved on a case-by-case basis. In this study one of the potential solutions, inserting helical reinforcement by a screwing motion, is further explored by presenting the Automated Screwing Device and its potential application domains in 3DCP.
