ANCHORING APPARATUS FOR RE-PRESTRESSING OF STRAND

摘要

The present invention relates to an anchoring device for a prestressed material of re-prestressable configuration using a re-prestressing block forming an external threaded part for each strand which can anchor a plurality of strands simultaneously, and by anchoring using a wedge coupling block (re-prestressed block), which is possible to be re-prestressed and forms a thread on an outer part for each of strands, and when needed, configured to introduce an additional pre-stress by re-stressing a strand in a predetermined range.
