Reinforcement system for concrete structures and a method for reinforcing an elongate concrete structure

Method for reinforcing an elongate concrete structure, where the reinforcement comprises at least a first and second set of reinforcement elements, each set comprising a number of uniformly shaped units, configured to be assembled and tied together prior to concreting, to form reinforcement, inside and around which concrete is poured, comprising:

• providing at least the first set of reinforcement elements, comprising several looped, winded or coiled units, interconnected by means of being fixed to at least one interconnecting flexible band, arranged in a reduced volume, flat packed condition and configured to be delivered to a construction site;
• stretching out the first set of reinforcement elements to its full length in formwork in situ;
• placing the second set of the reinforcement elements as reinforcement bars in position with respect to said first set of stretched out reinforcement elements;
• and
• then tying the first and second sets of reinforcement elements together,
• where at least a second row of said first set of reinforcement elements, comprising several looped, winded or coiled units, is arranged adjacent a first row in an overlapping configuration, thereby providing a row of closed loop like opening, into which a number of straight reinforcing bars, with larger diameters than the reinforcement bars incorporated in the second set of reinforcement elements, are threaded and tied to the contacting points, thereby providing a reinforcement for an incorporated integrated girder.
