Process for reinforcing a construction structure, and structure thus reinforced

摘要

Process for reinforcing a construction structure where, laid on one portion of said structure, is at least one portion of a reinforcement (10) of elongated shape comprising continuous fibers in the longitudinal direction of said reinforcement, which are combined with a polymer matrix, wherein said process comprises a step of removing the polymer matrix in one portion (20) of the reinforcement so as to release the fibers of the reinforcement in order to allow their rearrangement following their release from the polymer matrix. It is thus possible to optimize the binding configuration of the reinforcement with a portion of the structure to be reinforced.

主权项

1. A method for reinforcing a construction structure, the method comprising:
providing a reinforcement of elongated shape laid on a surface of said structure, said reinforcement comprising continuous fibers in a longitudinal direction of said reinforcement, said fibers being combined with a polymer matrix; removing the polymer matrix in at least one portion of the reinforcement; releasing the fibers in said at least one portion of the reinforcement from the polymer matrix; rearranging the released fibers of said at least one portion of the reinforcement; and bonding the rearranged and released fibers of said at least one portion of the reinforcement directly onto a portion of the surface of the structure to be reinforced, wherein the surface of the structure is reinforced with two reinforcements that each comprise fibers released from their polymer matrix in respective portions of the two reinforcements, and wherein rearranging the released fibers of said portions of the reinforcements comprises superposing said portions one on top of the other for bonding the fibers of said portions directly to the surface of the structure to be reinforced.
