Structural Strengthening Systems

Prestressing system for the structural strengthening of concrete structures after the concrete has hardened

The post-tensioned CFRP plate prestressing system is designed with compact anchorage components that maintain consistent tension throughout the structure's service life. Instead of cutting channels into the concrete, the anchors can be mounted directly onto the surface, thanks to a wave-shaped profile that simplifies installation and preserves the integrity of the original structure. The clamping mechanism combines curved surfaces, serrated grips, and adhesive bonding to hold the CFRP plate securely in place, ensuring reliable performance with built-in capacity beyond design requirements. This setup saves time, reduces labor, and minimizes structural disturbance.

Features

The reverse tensioning approach allows full flexibility in defining the effective length of the prestressing system, without being limited by site conditions.
Although compact in appearance, the anchorage is designed with an extended clamping chamber that increases contact with the CFRP plate and enhances both grip and load transfer.
A curved and serrated surface profile, combined with adhesive bonding, ensures secure clamping of the CFRP plate during tensioning.
The integration of wave-shaped geometry, serrated grip, and adhesive allows anchors to be mounted directly onto the concrete surface, avoiding groove cutting and preserving the original structure, saving time and labor.
Optimized anchor bolt size and layout simplify drilling and reduce the risk of hitting internal reinforcement.
