Pre-Tensioned CFRP Plate Prestressing System
Structural Strengthening Systems
Prestressing system for the structural strengthening of concrete structures prior to the casting of concrete
Structural strengthening of concrete elements before casting is crucial for ensuring long-term performance, especially in demanding construction environments. The pre-tensioned CFRP plate prestressing system offers a reliable method for applying tension to carbon fiber plates prior to pouring concrete. This approach follows a traditional tensioning process and is suitable for controlled job sites. It features a complete anchorage setup, including fixed anchor bolts, locking bolts, and eccentric adjustment sleeves, to maintain proper alignment and consistent tension throughout installation. Designed for single-layer CFRP plates up to 100 mm in width, this system ensures stable, secure prestressing that meets both structural and safety requirements from the earliest stage of construction.
| Model | Anchor block width (mm) (fixed end/tensioning end) | Anchor block length (mm) (fixed end/tensioning end) | Fixed anchor bolt (size/quantity) | Anchor locking bolt (size/quantity) | Eccentricity adjustment unit | Tension rod |
| 333/320 | 150/175 | M16/12 | M12/20 | 12 sets | M20 | |
| 357/300 | 205/210 | M16/10 | M12/20 | 14 sets | M18 |
Pre-tensioned CFRP plate prestressing systems are commonly used to strengthen bridges, buildings, and other load-bearing structures, improving both their load capacity and seismic resistance. Their lightweight yet high-strength characteristics make them ideal for projects where reducing structural weight is essential without compromising on durability or stability.
