DEVICE FOR ANCHORING REINFORCING ROPES Russian patent published in 2004 - IPC

FIELD: manufacture of reinforced concrete structures using steel ropes.

SUBSTANCE: device has yoke with hole expanded to form truncated cone with central angle of 12^o 05' - 13^o 15', or better 13^o, between generating lines, that accommodates longitudinally split three-fraction conical insert with central angle between generating lines being 13^o20' - 14^o 35', or better 14^o 35', and with central duct to receive rope, insert fractions being mounted for providing clearance between adjacent side surfaces of their split, better parallel ones; common annular groove is made on fractions of conical insert, preferably on sides or on end turning into cylindrical part of its larger base; this groove is designed to receive annular flexible member integrating these fractions; yoke has conical drilling on smaller base end opposing conical insert; smaller base of drilling is connected, better through cylindrical duct, to smaller base of conical expansion whose diameter is larger than that of strand reinforcement by at least 1.13 times.

EFFECT: enhanced reliability of mechanical design of device and of rope fixation thereon.
