Problems solved by technology

Devices capable of dynamically embedding steel wires are known, but in practice there are disadvantages to using wire-like reinforcement
Reinforcement is less flexible, especially in complex member structures, which is disadvantageous
Another disadvantage is the poor adhesion of steel wires in concrete structures and their susceptibility to corrosion in areas where the reinforcement is not adequately covered by concrete
Even substituting non-corrodible plastic wires for steel wires, in addition to lacking strength, can only bond inadequately to the surrounding matrix
The features of the method in the known solutions are likewise not applicable to suitable reinforcing bars, since for example the aforementioned hard plastic wires are less technologically demanding for transport

Abstract

The invention relates to a method and to a device for producing a concrete component comprising concrete and a textile reinforcement composed of a reinforcement fiber strand (28), wherein firstly a yarn (20) is impregnated with a mineral suspension (35), and the at least one reinforcement fiber strand (28) is formed. According to the invention, the reinforcement fiber strand (28) is guided by means of a moving apparatus such that the reinforcement fiber strand (28) is inserted into a concrete strand (4), applied to a concrete layer (2) or applied to a vertical lateral surface of a plurality of concrete layers deposited one on top of the other such that an externally arranged vertical reinforcement is produce. Furthermore the reinforcement fiber strand (28) is enclosed by the concrete directly during the deposition or subsequently, before the mineral suspension (35) is cured. The invention further relates to the reinforced concrete component (1).

Description

technical field [0001] The invention relates to a method for producing reinforced concrete elements comprising matrix material concrete and a fiber fabric reinforcement (textileBewehrung) formed from at least one reinforcing fiber strand (Bewehrungsfaserstrang), wherein the yarn is impregnated with a mineral suspension, The at least one reinforcing fiber strand is thereby formed. The invention also relates to a device for producing reinforced concrete elements comprising matrix material concrete and a reinforcement formed from at least one fiber strand of a fiber fabric reinforcement, wherein a reinforcing fiber strand supply mechanism is provided as a As for the means for outputting said reinforcing fiber strands, said reinforcing fiber strand supply mechanism comprises a dipping device which provides reinforcing fiber strands formed by soaking yarns in a mineral suspension. [0002] The invention also relates to a reinforced concrete element in which the demolition-free for...
