METHOD FOR TENSIONING AND FIXING OF ROPE REINFORCEMENT Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: method relates to production of articles and structures with pretension of reinforcement. According to method, anchor sleeve is preliminarily slipped over rope reinforcement. Sleeve is compressed over its entire length and thread is made in surface of sleeve over its section of length equal to 0.8 diameter of sleeve. Reinforcement with anchors is located in passages of structure and reinforcement is tensioned. After tensioning of reinforcement, nut is screwed on sleeve up to resting against end of structure, and force of reinforcement of tension is transmitted to structure. As nut rests against end of structure, anchor sleeve can be located within limits of structure itself. Aforesaid method is simple and requires less metal. EFFECT: higher efficiency. 2 dwg
