  • Method of reinforcing structural components
    Patent number: 5115622
    Abstract: Metal reinforcing members (3) are attached by bonding to a surface in the tension zone (1a) of a concrete structure component (1) for reinforcing the component. To prevent the ends of the reinforcing members (3) from separating from the structural component (1) when the component is subjected to load, attachment elements (4) clamp the ends of the reinforcing members against the surface of the component in addition to the bonding action. The attachment elements (4) apply such high compressive forces to the structural component, so that potentially damaging tension and shear forces can not be effective.
