A method for fastening a flat strip lamella ( ) to the surface of a building component ( ). According to the inventive method, the face ( ) of the flat strip lamella ( ) is pressed against the surface of the building using an adhesive coating ( ) consisting of a reaction resin applied in a paste-like consistency ( ) and hardened to form an adhesive joint. The flat strip lamella ( ) comprises a plurality of carbon fibers which are embedded in a binder matrix ( ) and placed parallel to each other in a longitudinal direction. In order to increase the speed at which the adhesive coating hardens, the invention provides that an electrical current flows through least one part of the carbon fibers ( ), heating the flat strip lamella ( ) which in turn heats the adhesive coating ( ).

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

Flat strip lamella for reinforcing weight-carrying or weight-transferring building components. It has a composite structure consisting of a plurality of pliant or loose-flex supporting fibers ( ) aligned parallel to each other, and a binding matrix ( ) which connects the supporting fibers to each other so that they are shear-resistant, and is fastenable by means of an adhesive ( ) by its broad side to the surface of the building component ( ) that is to be reinforced. So that the flat strip lamella, to which the binding matrix gives rigid elastic form, can also be bent over corner edges of a building component ( ), the invention proposes that the binding matrix ( ) be removed, in at least an intermediary area ( ), by uncovering the supporting fibers ( ), and that the uncovered supporting fibers be subjected to a liquid or pasty thermosetting plastic, in order to stabilize the bent-over condition.
