Long Coiled Reinforcement Produced by Drawing

Аннотация

Long multiturn coiled reinforcement may be produced by drawing without torsion. It offers several benefits over existing Vr-1 reinforcement. The influence of the roller inclination and the number of helical turns on the drawing force is studied. The mechanical properties of a four-turn helical profile are compared with those of Vr-1 reinforcement (diameter 4 mm).
