Technical Standards for Products of Unbonded Pre-stressed Tendons
The unbonded pre-stressed tendons are mainly used in the post-tensioned pre-stressing systems.
The difference between the unbonded pre-stressed tendon and the bonded pre-stressed tendon is that the unbonded one will not bond to the concrete surrounding it and will always
allow the vertical and relative sliding between the pre-stressed tendon and the surrounding concrete
during operation.
The pre-applied force depends complete on anchors to be passed to the concrete.
During construction, the unbonded tendons can be put into the form woks just as normal reinforcing bars.
After the concrete pouring step is finished and the concrete attains to a designed strength, the tensioning
and anchoring work can be done. There is no need to reserve ducts and there is no need to carry out some
steps such as grouting and etc.
Therefore unbonded pre-stressed tendons have the following characteristics:1. When a large pre-stressed slab is used, this product is very convenient for supporting formworks.
There is no need to build formworks for internal columns and beams. At the same time, it is convenient
to use big formworks for inner and outer surfaces, which speeds greatly the construction.2. This product helps to save about 28% of reinforcing steel bars, about 6% of concrete usage and reduce
the usage of formworks and the waste of transportation and working time.3. The bars can be rapidly placed onto the pre-stressed slab, which avoids the step of drilling through the beam bars like in the normal beam-slab structures
of reinforcement concrete.
This decreases the construction difficulties.4. Unbonded tendons have little friction and are easy to be bended into curves with various spans, which makes
them suitable for structures with complicated and continuous curved reinforcing bars.5. This product helps to expand the utilization area and increase the structural performance.6. It is convenient for structural construction, upholstering and equipment installation.
7. The number of floors can be increased with same building height and interior net story height.
