A method and an apparatus for producing a concrete component, comprising concrete and a textile reinforcement composed of a reinforcement fiber strand (28), wherein first a yarn (20) is saturated with a mineral suspension (35) and forms the at least one reinforcement fiber strand (28). According to the invention, the reinforcement fiber strand (28) is fed by means of a moving device, so that the reinforcement fiber strand (28) is placed in a concrete strand (4), placed on a concrete layer (2), or placed on a vertical side surface of a plurality of concrete layers placed on top of each other, so that a perpendicular reinforcement is produced when arranged on the outside, and wherein the reinforcement fiber strand (28) is further enclosed by the concrete immediately upon placement or subsequently before the mineral suspension (35) has cured. The invention also relates to a reinforced concrete component (1).
A method for producing a reinforced concrete component comprising a concrete matrix material and a textile reinforcement of at least one reinforcement fiber strand, wherein a yarn (20) is saturated with a mineral suspension (35) and is used to form the at least one reinforcement fiber strand (28), characterized in that the at least one reinforcement fiber strand (28) is dispensed from a moving device for dispensing the at least one reinforcement fiber strand (28), so that the at least one reinforcement fiber strand (28) is introduced into at least one concrete strand (4) according to a first embodiment, is placed on at least one concrete layer (2) according to a second embodiment or, according to a third embodiment, is placed on at least one vertical side surface of a plurality of superimposed concrete layers (2) of the concrete component (1) or is placed in the concrete strand (4) applied there, so that a perpendicular reinforcement (26) is produced which is arranged on the outside, and wherein the at least one reinforcement fiber strand (28) is further enclosed by the concrete immediately upon deposition or subsequently, before the mineral suspension (35) has cured.
An apparatus for producing a reinforced concrete component (1), the concrete component (1) comprising a concrete matrix material and a reinforcement of at least one textile reinforcement fiber strand (28), wherein a reinforcement fiber strand delivery unit (40, 50) is provided as a device for dispensing the reinforcement fiber strand (28), comprising an impregnation device (33) forming from a yarn (20) the reinforcement fiber strand (28) saturated with a mineral suspension (35), characterized in that the reinforcement fiber strand delivery unit (40, 50) is movable relative to a substrate or a previously produced concrete layer (2) and is adapted to place the reinforcement fiber strand (28), according to a first embodiment, in a concrete strand (4) dispensed from an extrusion nozzle (6), to place it, according to a second embodiment, on a previously applied concrete layer (2), or to place it, according to a third embodiment, on a vertical side surface of a plurality of superimposed concrete layers (2) of the concrete component (1), or to place it in the concrete strand (4) to be applied thereon, so that, in each of the embodiments, immediate or subsequent enclosure of the reinforcement fiber strand (28) with concrete can take place before the mineral suspension (35) has cured.
A reinforced concrete component (1) produced in an extrusion-based additive manner, comprising concrete layers (2) formed by at least one concrete strand (4) extruded from at least one extrusion nozzle (6), characterized in that the reinforcement provided is a yarn (20) which, for installation in the concrete strand (4) or between two concrete strands (4) or between two concrete layers (2), is saturated with a mineral suspension (35) to form at least one reinforcement fiber strand (28) which is completely enclosed with concrete in the concrete component (1), the installation and the enclosure having taken place before curing of the mineral suspension (35), the at least one reinforcement fiber strand (28) being provided as longitudinal reinforcement (22), transverse reinforcement (24) and/or vertical reinforcement (26).
