Reinforcement element for load-carrying or load-transferring structural parts and method for fixing said reinforcement element to the surface of a structural part

A reinforcing element for load-bearing or load-transmitting structural components (12) comprising

• a flat strip lamella secured to a structural component outer surface by means of an adhesive layer (16),
• wherein the flat strip lamella is comprised of a plurality of parallel to each other and parallel to the lamella longitudinal direction oriented reinforcing fibers (26) embedded in a binder matrix (28),
• wherein the flat strip lamella further comprises anchor plates (18) having a tube (46) with at least partially flexible, preferably with right-angle internal cross section, and lever elements (48, 50) pressed into the tube (46), and that the respective lamella ends are tensioned between the facing wedge surfaces (52, 54) of the wedge elements (48, 50) and are adhered to these.

A reinforcing element for load-bearing or load-transmitting structural components (12) with a flat strip lamella secured to a structural component outer surface by means of an adhesive layer (16),

• wherein the flat strip lamella is comprised of a plurality of parallel to each other and parallel to the lamella longitudinal direction oriented reinforcing fibers (26) embedded in a binder matrix (28), wherein at least one of anchor plates (18) exhibits a shoulder as abutment for a tensioning device engaging in the lamella longitudinal direction.

Process for securing a flat strip lamella (10) to the outer surface of a structural component (12), the flat strip lamella comprised of a plurality of reinforcing fibers (26) embedded in a binder matrix (28), parallel to each other and extending in the lamella longitudinal direction, wherein a broad side of the flat strip lamella (10) is pressed against the structural component surface via an adhesive layer (16) applied in a viscous consistency, preferably a reaction or curing resin, and the adhesive layer is hardened with formation of an adhesive bonding, wherein the lamella ends are forced, formed, and/or materially connected with an anchor plate (18), that one of the anchor plates (18) is secured to a structural component and the other anchor plate (18) prior to or after application of the adhesive is engaged with a tensioning mechanism secured to the structural component, and that the flat strip lamella (10) is acted upon with a pull force directed in the lamella longitudinal direction (38) with production of an elastic deformation, and that the flat strip lamella pre-tensioned in this manner is held or pressed against the structural component surface until hardening of the adhesive.

Process for securing to the outer surface of a structural component (12) a flat strip lamella (10) comprised of a plurality of reinforcing fibers (26) embedded in a binder matrix (28), parallel to each other and extending in the lamella longitudinal direction, wherein a broad side of the flat strip lamella (10) is pressed against the surface of the structural component via an intermediate adhesive layer (16) applied in a viscous consistency, preferably a reaction or curing resin, and wherein the adhesive layer is hardened with formation of an adhesive bonding, wherein the lamella ends are force-, form-, and/or materially-connected with an anchor plate (18), that the anchor plates (18) are first secured to a tension beam with production of an elastic pre-tension in the flat strip lamella (10), that the tension beam is pressed or held with the adhesive side of the flat strip lamella (10) against the structural component outer surface until the adhesive is hardened, and that subsequently the tension beam is removed from the flat strip lamella.
