Strands or prestressing steel wire positioning device for framing, has traction unit for traction of fastener unit, and realizing course of translation movement of strand via framing and another traction unit for realizing reverse course

摘要

The device has a fastener unit (M) fixed temporarily at the end of a strand (T). A traction unit (400b) provided for the traction of the unit (M) is controlled to permit to realize the course of translation movement of the strand through a framing (200). The unit (M) is connected to a traction unit (400a) for realizing reverse course at the unit (M) so that the unit (M) has back and forth motion.
