Abstract (en)

[origin: EP1287957A1] Long carbon fibers f0 are stretched between a couple of anchor-installing bases 40L, 40R. Continuous carbon fibers f are drawn out of a reel 34 on a carrier 30 and helically wound around the stretched long carbon fibers f0, by combination of rotation of the stands 40L, 40R with unidirectional travel of the base 30. A reinforcing element composed of the long carbon fibers f0 and the continuous carbon fibers f is set in a molding box 60, and fresh concrete is cast from a tank 62 in the molding box 60. Since the stretched reinforcing element is embedded in cured concrete, a fabricated concrete member is very strong with high reliability on quality and performance. <IMAGE>
