3D concrete printing with flexible reinforcing structure
A concrete construction is made by 3D concrete printing and comprises: - two or more layers (100, 102) of cementitious material extruded one above the other, and - a reinforcing structure (104) reinforcing the two or more layers (100, 102). The reinforcing structure (104) has a length and a height. The reinforcing structure (104) comprises at least two flexible longitudinal elongated steel elements (208, 210, 308, 310) running in lengthwise direction. The reinforcing structure (104) further comprises one or more flexible transverse steel elements (214, 314) forming an angle with the lengthwise direction so that these flexible transverse steel elements (214, 314) are present in the two or more layers (100, 102). The structure (104) further comprises a positioning element for positioning the at least two flexible longitudinal elongated elements (208, 210, 308, 310) and the flexible transverse steel elements (214, 314), a polymer coating or yarns making stitches. The polymer coating or the stitches are applied on the at least two flexible longitudinal elongated steel elements (208, 210, 308, 310), on the flexible transverse steel elements (214, 314) and on the positioning element thereby making a bond between the at least two flexible longitudinal elongated steel elements (208, 210, 308, 310), the flexible transverse steel elements (214, 314) and the positioning element. A concrete construction made by 3D concrete printing comprises: - two or more layers (100, 102) of cementitious material extruded one above the other, and - a reinforcing tape (104) reinforcing at least two of the layers (100, 102). The reinforcing tape (104) comprises at least one steel cord (106). The presence of a steel cord (106) gives more flexibility to the reinforcement.
