Prestressed Concrete Post Tension Cable Wire Monostrand Anchors
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.
Our anchor system has below features:
- Wide range application, it can anchor with standard strength of 1570Mpa-2000Mpa, with the diameter of 8mm,9mm,11mm,12.7mm,15.2mm,18mm pc strand and the high-strength steel wire with standard strength of 1570Mpa-1670Mpa, with the diameter of 5mm,7mm.
- Wide range of choice, GYM series anchor system is suitable for the number of pc strand from 1-55 tendons, and can be produced as per customer requirement.
- With good stressing self-anchored function, Easy operation.
- With high anchoring efficiency and reliable anchor.
- The anchor structure size is reasonable, which can satisfy anchorage efficiency coefficient but also achieve anchorage of strand of short distance.
Definition of Parts:
Wedge:
Wedge is the key part of anchor system, which is made by high-class alloy steel 20CrMnTi. Its form is divided into two-chip and three-chip. The system apply to the two-chip GYM15 series, it can be used for round anchorage, flat anchorage, but also used for porous coupler.
Anchor head:
Anchor head is the key part of bearing the prestressing tension, The round anchor head is made by 45# high-quality carbon construction steel, and the flat anchorage is made by 40Cr steel. Anchor head include round anchor head and flat anchor head
Anchor Bearing Plate:
Anchor bearing plate is the key component, which transfer the load from anchor head to concrete under anchor. The method of transfer and distribution of stress affect the anti-cracking and load capacity of concrete. Bursting reinforcement used for distributing the concrete. For prevent concrete from crazing, and use the bursting reinforcement for strengthening tendons.
Metal Bellows:
Metal bellows used for post tensionning prestress concrete structure or constructive pore-forming. It can be divided into round and flat by the section shape; divided into standard enhanced by radial stiffness; divided into metal and plastic tubes by materials, and the metal duct can be divided into galvanized and non-galvanized.
