Abstract (en)

[origin: WO2020256559A1] A supporting beam 1 has a reinforcement 3 consisting of a number of parallel rods 5 extending in the longitudinal direction of the supporting beam and a number of strands 7, 9 of basalt fibers which are wound helically to the left and right around the rods, thereby crossing each other. In the places 13, 15 where the strands 7, 9 are in contact with the rods 5, the strands are attached to the rods and at the places where the strands 7, 9 intersect the strands are attached to each other. The reinforcement 3 is embedded in concrete 11, wherein a lower part 1A of the supporting beam which is subjected to tension during use has a trapezoidal cross-section and an upper part 1B of the supporting beam which is subjected to compression during use has a rectangular cross-section and the cross section of the lower part is smaller than the cross section of the upper part.
