Reinforcement of Existing Concrete Structures: Outplate Method

Reinforcement of Existing Concrete Structures: Outplate Method

High bending reinforcement effect and high crack control effect! Suitable for the construction of RC and PC hollow slab bridges.

The Outplate method is a reinforcement technique that involves tensioning a prefabricated CFRP plate (Outplate) with anchoring bodies at both ends, fixing and bonding it to an existing concrete structure. Compared to conventional continuous fiber sheet bonding methods, tensioning the Outplate allows for the introduction of prestress into the concrete. This method achieves significant reinforcement effects with a minimal amount of reinforcement material. Since thin CFRP plates are used as tensioning materials, there is almost no change in the appearance or cross-section after reinforcement, making it particularly suitable for the construction of RC and PC hollow slab bridges. 【Features】 ■ High bending reinforcement effect ■ High crack control effect ■ Recovery of deflection ■ Improved durability ■ Minimal maintenance ■ Reinforcement above the supports of continuous girders is possible from the underside *For more details, please refer to the PDF document or feel free to contact us.
