1. A method for reinforcing a concrete component comprising the following steps:
drilling a borehole into the component to be reinforced,
screwing a first threaded sleeve into the borehole, so that the said first threaded sleeve assumes a first position in the component,
screwing a second threaded sleeve into the borehole, so that the said second threaded sleeve assumes a second position in the component, which differs from the first position,
inserting an elongate clamping element through the second threaded sleeve and into or through the first threaded sleeve, and axial clamping of the first and of the second threaded sleeve in such a manner that the first and the second threaded sleeve generate opposed bond stresses in the respective component.
