Post Tensioning System
Product Description
Prestressing force is the compressive stress applied to a structure
in advance during construction in order to improve the service
performance of the structure.
Prestressing force is the compressive stress applied to a structure
in advance during construction in order to improve the service
performance of the structure. Pre-added compressive stress during
the service period of the structure can fully or partially offset
the tensile stress caused by the load, avoiding the destruction of
the structure, and is commonly used in concrete structures.
The Concept of Prestressing Force
1. Prestressing force is the stress applied to the member before
loading;
2. Prestressing force makes full use of the compressive strength
and tensile strength of the material, and can improve the crack
resistance of concrete, but will not improve the load carrying
capacity of the member;
4. The inverted arch of the member caused by prestressing can
offset the deflection of the constant load, but it has almost no
effect on the deformation caused by variable loads;
5. prestressing is an internal force in the member, which does not
destabilize the member, but rather improves the stability of the
member. For example, prestressing can be applied to precast piles
to improve the stability of the piles during transportation and
pile driving;
A prestressing system usually consists of several components,
including anchor, wedge, strand, and bellows.
