METHOD FOR REINFORCING A DOUBLE-SHELL STRUCTURE

METHOD FOR REINFORCING A DOUBLE-SHELL STRUCTURE

The invention concerns a method for reinforcing a double−shell structure in which a cellular core (2) is arranged between a first shell (5) and a second shell (6). In the method according to the invention, at least one cavity is formed in the double−shell structure from an opening in the first shell...

description The invention concerns a method for reinforcing a double−shell structure in which a cellular core (2) is arranged between a first shell (5) and a second shell (6). In the method according to the invention, at least one cavity is formed in the double−shell structure from an opening in the first shell into the cellular core (2) so that the cavity substantially extends through the cellular core (2) to the second shell. Fixative (8) is injected into the cavity. A stiff bar (7) is introduced into the cavity, whereupon excess fixative (8) is allowed to pass out of the cavity. Finally, the fixative left in the cavity is cured.

Cette invention a trait à un procédé de renforcement d'une structure à double coque, dans le cadre duquel on place une âme alvéolaire (2) entre deux coques (5, 6). On ménage au moins une cavité dans la structure double coque à partir d'une ouverture dans la première coque, laquelle cavité traverse l'âme alvéolaire (2) d'une coque à l'autre. On injecte un agent fixatif (8) dans la cavité. On introduit une barre rigide (7) dans la cavité, ce qui a pour effet d'évacuer de la cavité l'excès d'agent fixatif, l'agent fixatif resté en place étant alors mis à prendre.
