Method for fastening a flat strip lamella to the surface of a building component

A process for securing a flat strip lamella to a construction component surface, the flat strip lamella having a first end and a second end and comprising a plurality of carbon fibers extending parallel to each other in a longitudinal direction in a binder matrix, said process comprising:

• applying an adhesive layer directly to the construction component surface, the adhesive layer comprises a reaction resin in a pasty consistency;
• pressing the flat strip lamella against the adhesive layer;
• and
• hardening the adhesive layer to produce an adhesive bond;
• wherein an electrical current is conducted through at least a portion of the carbon fibers such that the adhesive layer is heated via the flat strip lamella, wherein a metallic contact plate is pressed against each of the first and second ends of the flat strip lamella;
• and
• wherein prior to the heating process the electrical resistance (R) in the flat strip lamella extending between the metallic contact plates is measured, and the electrical voltage and/or the current strength (amperage) is adjusted to a defined value according to the value of a predetermined surface area dependent heating power under consideration of the measured resistance.
