prestressing multi holes round wedge anchorage|post tension anchor

Introduction of prestressing multi holes round wedge anchorage: Prestressing multi holes round wedge anchorage are composed of tensioning anchor,fixed end anchor,connectors. It can be used to lock the steel strand wires on/under classes of 2000Mpa standard strength,which is usually in diameters of 12.7mm /12.9mm/15.2mm/15.7mm. Prestressing multi holes round wedge anchorage can be used for the different kinds of strand wires produced according to ASTM/BS/JIS/JIG/AS and other international standards respectively only if its technical parameters shall mary the related detail materials. 1. prestressing multi holes round wedge anchorage can be used to anchor PC strand which strength below 2000Mpa. 2. prestressing multi holes round wedge anchorage has excellent static load anchoring performance. Anchoring efficiency factor is ηA≥0.95 and elongation εa≥2% , and meet International strandard FIP 1993 3. It 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. It 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.
