Title:
METHOD AND DEVICE FOR PRODUCING CARBON LONG-FIBER-REINFORCED CONCRETE MEMBERS
Document Type and Number:
WIPO Patent Application WO/2001/068333
Kind Code:
A1
Abstract:
Carbon-long-fiber-reinforced concrete members are produced. Carbon long fibers (f¿0?) are extended between a pair of anchor attaching stands (40L, 40R) and a carriage (30) is moved while rotating the anchor attaching stands (40L, 40R), whereby continuous carbon long-fibers (f) are spirally wound around the carbon long-fibers (f¿0?). Used as a bar arrangement, this is received in a form (60) and concrete is poured from a concrete tank (62) into the form (60), whereby the bar arrangement, in which the continuous carbon long-fibers (f) are spirally wound around carbon long-fibers (f¿0?), is embedded in the concrete, producing a carbon-long-fiber-reinforced concrete member of high strength.
