Product Overview
The 1-hole round anchor head is a prestressed anchorage assembly designed specifically for single strands. It consists of an anchor ring, wedges (with threaded tooth surfaces), and a locking device. Commonly available in models like YJM15-1, it is used for reliable anchoring of strands in infrastructure projects.
✅ Core Structure & Materials
Anchor Ring: Made of 45# steel with quenched and tempered heat treatment; its surface is typically finished with black oxidation, and it features a conical inner hole to match the wedges.
Wedge Assembly: Crafted from alloy steel, usually composed of 2-3 pieces combined into a conical shape. The inner side is equipped with oblique fine teeth (to enhance friction with strands), and some wedges have elastic grooves to optimize anchoring performance.
Locking Device: Optional nuts (fastened via threads) or pins to prevent wedge loosening or disengagement.
✅ Key Advantages
Low Preload Loss: Thanks to the conical hole + wedge structure, preload loss is reduced to less than 5% (compared to traditional U-block anchors).
Easy Installation: Simply thread the strand through the anchor ring, fit the wedges, apply preload, and secure with the locking device.
High Reliability: The tooth surface hardness and material strength meet industry standards, enabling stable anchoring of single unbonded/bonded strands.
Wide Application Scope: Suitable for infrastructure scenarios like anti-floating anchor bolts, pretensioning construction, and underground engineering support.
✅ Typical Applications
Anti-floating anchor bolt projects for basements/underground passages;
Pretensioning construction of precast concrete components;
Support projects such as mine roadways and slope reinforcement.
