External Prestressing Systems

External prestressing is one of the important branches of post tensioned prestressing systems.

Compared with internal prestressing structures, its prestressing tendons are located outside the main section of the load-bearing structure,

and the prestressing is transmitted through anchoring zones and turning blocks directly or indirectly connected to the main section of the structure.

ADVANTAGES

The external prestressing system adopts non bonded steel strands and an anti-corrosion structure in the anchorage zone, which is safe and reliable, with good anti-corrosion and anti fatigue performance. Special devices are designed in the system to effectively reduce the harm caused by cable vibration.

The construction of the external prestressing system is simple, easy to detect and maintain, and the cables can be replaced if necessary.

The steering device has a reasonable structural setting, which can evenly transmit loads and achieve cable adjustment and replacement functions.

USE

The application of external prestressed structural system is very extensive, which can be used for new structures such as prestressed concrete bridges, special structures, and building engineering structures, as well as for the reconstruction, reinforcement, and maintenance of existing concrete structures.

It can also be used for temporary prestressed concrete structures or construction of temporary steel cables.
