ATTACHMENT FOR ROTATING STRANDED WIRE WEDGE, TENSION KIT FOR STRANDED WIRE, AND STRANDED WIRE CONNECTION COUPLER

摘要

A stranded wire wedge (50), an anchor head (10), and an attachment (20, 20A, 20B, 20C) are used when tensioning a stranded wire. The stranded wire wedge (50) has an inner surface where a plurality of helical grooves (51b) for engaging with the helical outer peripheral surface of the stranded wire is formed, the stranded wire wedge (50) being attached to the outer peripheral surface of the stranded wire. The anchor head (10) has a hollow portion (11) in which the stranded wire wedge (50) is wedged. The attachment (20, 20A, 20B, 20C) has: an accommodation space (21) in which the large-diameter end portion of the stranded wire wedge (50) is accommodated; and a through hole (22) connected to the accommodation space (21) and having a dimension allowing the stranded wire to pass therethrough, wherein a rotating member (25, 25A) for assisting the rotation of the stranded wire wedge (50) along the helical outer peripheral surface of the stranded wire when the stranded wire (1) coming out from the through hole (22) is tensioned is provided in the accommodation space (21).
