Method and device for producing a reinforced concrete component, and concrete component
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 ).
1. A method for producing a reinforced concrete component ( 1 ) comprising a concrete matrix material ( 2 , 4 ) and a textile reinforcement of at least one reinforcement fiber strand ( 28 ), 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 reinforcement fiber strand delivery unit ( 40 , 50 ) for dispensing the at least one reinforcement fiber strand ( 28 ) moved by a manipulation device ( 90 ), so that the at least one reinforcement fiber strand ( 28 ) is placed in at least one concrete strand ( 4 ) applied on at least one vertical side surface of a plurality of superimposed concrete layers ( 2 ), so that a perpendicular reinforcement ( 26 ) is produced which is arranged on an outer side of the reinforced concrete component ( 1 ), and wherein the at least one reinforcement fiber strand ( 28 ) is further enclosed by the concrete matrix material ( 2 , 4 ) immediately upon deposition or subsequently, before the mineral suspension ( 35 ) has cured.
2. The method according to claim 1 , wherein a flowable cement suspension or mortar is placed between two of the concrete layers ( 2 ) for improved adhesion between the reinforcement fiber strand ( 28 ) and the concrete layer ( 2 ).
3. The method according to claim 1 , wherein a reinforcement fiber strand delivery unit ( 40 , 50 ) arranged on the manipulation device ( 90 ) comprises a strand preparation device ( 62 , 72 , 82 ) and an impregnation device ( 33 ), wherein, according to a first alternative, the at least one reinforcement fiber strand ( 28 ) is formed stationarily in the strand preparation device ( 62 , 72 , 82 ) and transferred to the reinforcement fiber strand delivery unit ( 40 , 50 ), wherein, according to a second alternative, the at least one reinforcement fiber strand ( 28 ) is formed stationarily in the strand preparation device ( 62 , 72 , 82 ), is wound up into a strand coil ( 74 ), the strand coil ( 74 ) is connected to the reinforcement fiber strand delivery unit ( 40 , 50 ) in such a way that the at least one reinforcement fiber strand ( 28 ) is fed from the strand coil ( 74 ) to the reinforced concrete component ( 1 ), wherein, according to a third alternative, the reinforcement fiber strand delivery unit ( 40 , 50 ) comprises a mobile strand preparation device ( 62 , 72 , 82 ) and the at least one reinforcement fiber strand ( 28 ) is formed in the reinforcement fiber strand delivery unit ( 40 , 50 ).
4. The method according to claim 1 , wherein the at least one reinforcement fiber strand ( 28 ) is formed by saturation with the mineral suspension ( 35 ) by performing an impregnation process with the impregnation device ( 33 ) as a padder; squeezing off excess suspension ( 35 ) as well as shaping of the cross-section of the reinforcement fiber strand ( 28 ) being performed with the aid of a strand nozzle ( 34 ) which is conical or funnel-shaped in a dispensing direction.
5. The method according to claim 1 , wherein the concrete layers ( 2 ) form a permanent formwork and flowable concrete is filled into the permanent formwork, wherein the entire formwork is filled at once.
