Description of stressing flat anchorage
Compact anchorages to facilitate the installation and grouting of the tendons.
Anchorages design to satisfy the Design requirements of Int’l Standards
Wide selection of anchorages & jacks from 1 up to 37 strands (round) & 2 up to 5 strands (flat) allowing the Consultants to provide an economical design and specify improved technical feasibilities (proper cable deviations & losses).
37 different anchorage sizes and different types contributing to the Economy of the Design & Construction.
Easy connection with standard or enlarged steel or plastic sheaths (flat and round).
1. stressing flat anchorage can be used to anchor PC strand which strength below 2000Mpa.
2. stressing flat anchorage has excellent static load anchoring performance. Anchoring efficiency factor is ηA≥0.95 and elongation εa≥2% , and meet International strandard FIP 1993<Post tensioned prestressing system acceptance advice>
3. stressing flat anchorage has excellent fatigue resistance. It pass 200 million fatigue resistance test which stress amplitude is 120MPa, and the upper limit of stress is 0.65fpk.
4. stressing flat anchorage has good self-anchor performance
5. The draw-in of anchor is ≤6mm.
6. The friction loss of anchor is ≤2.5%
7. We have kinds of anchorage and appropriate stressing equipments.
