METHOD OF REINFORCING MEMBERS MANUFACTURE FOR PRESTRESSED STRUCTURES Russian patent published in 2000 - IPC

FIELD: civil engineering for erection of prestressed structures with tensioning of reinforcement under conditions of construction. SUBSTANCE: method of reinforcing members manufacture from coil includes unwinding of rope reinforcement, its straightening and cutting into measured members. Each measured member ends is fixed by clamping devices and longitudinal force equalling 0.5-0.7 of rated resistance to tension of reinforcement is applied to one of ends. Then ends of measured member are released from clamps. In places of crumpling of reinforcement, anchor sleeves are installed and pressed around. EFFECT: reduced specific material consumption, higher accuracy of tensioning. 3 dwg
