Unbonded Internal Post-Tensioning

Unbonded internal post-tensioning facilitates simple bridge maintenance and inspection.

Internal post-tensioning systems that are not bonded are robust, dependable, and corrosion-proof. Systems can make use of Threadbars, wire tendons, strand tendons, and mono-strand tendons.

Unbonded internal post-tensioning systems are used as

Mono-strand tendons: Buildings are frequently constructed using bunched, greased, and PE-sheathed mono-strand tendons, which are also employed in the transversal post-tensioning of bridges.
Internal wire tendons: Bridges and other civil structures with solid cross-sections and slabs where it is necessary to evaluate the straining level subsequently are typical applications for internal wire tendons.
Unbonded strand tendons are frequently used in civil structures, such as bridges.
Threadbars: In projects involving the strengthening and restoration of infrastructure, unbonded internal bar post-tensioning systems are employed. The connecting of precast members, the fixation or tieback anchorages of steel structures, and transverse post-tensioning are examples of typical uses.

Features:

Monostrand systems and strand systems with up to 55 strands
Bar systems up to 47 mm in diameter
Systems with up to 84 wires
The tendon is typically constructed with corrosion protection, shipped to the site, and installed.
Grease, wax, or gel are examples of soft corrosion-prevention materials.
Low range of produced stress
Less worry tiredness
Monitoring of the putting pressure
Possible restressing, if necessary
Replaceable if necessary
