Anchorage Round Post-tensioning Anchor Head 4Holes
Description of Anchorage
Anchorage is a permanent anchoring device used in prestressed concrete and is an important part of applying the shrinkage force generated by the prestressed tendons to the construction. In post-tensioned structures or components, in order to maintain the tension of the prestressed tendons and transmit them to the inside of the concrete, the anchoring tool can improve the bearing capacity of the bridge, increase the span of the bridge, and reduce the weight of the bridge.
GYM System is consist of stress-end anchor, fixed end anchor,anchor coupler and corrugated pipe.
It can be divided into GYM13, GYM15, GYM18 series of round anchors and GBM13, GBM15 series of flat anchors, we also have high-strength steel wire GYM5, GYM7 series anchor.

Main Classification of Bridge Anchorage
General anchorage construction and installation method
The general anchorage construction and installation method are to put a small number of explosives at the bottom of the hole, expand it into a spherical shape after several anchorage constructions and installations, and finally put the explosives into the anchorage construction and installation. Compared with the hole anchorage construction and installation method, this method has the advantages of good anchorage construction and installation effect, high work efficiency, fast progress, and low consumption of explosives. This method is often used in the construction and installation of short pile anchors for shallow foundations.
Warm tips
1. The anchors should be kept properly, and there should be no rust, water, and other sundries in use.
2. Apply lubricant on the outer surface of the tool clip and the inner surface of the taper hole of the anchor plate before use, and often remove the debris on the surface of the clip.
3. Safety measures should be taken during tensioning, and no one can stand after the tensioning jack.
4. The anchor system should be used together and cannot be mixed with other systems.
