Abstract

L'invention propose un dispositif de centrage (10) prévu pour être monté sur une barre de renfort (12) du type fer à béton avant l'insertion de la barre de renfort (12) dans un trou de forage, caractérisé en ce qu'il comporte deux demi-coquilles (16, 18) prévues pour être fixées l'une sur l'autre en enserrant un tronçon (20) de la barre de renfort (12), chaque demi-coquille (16, 18) comportant des éléments de fixation (22) coopérant avec des éléments de fixation complémentaires (24) agencés sur l'autre demi-coquille (16, 18), et chaque demi-coquille (16, 18) comportant un organe de centrage (34) prévu pour venir au contact de la paroi interne du trou de forage après l'insertion en vue d'assurer le centrage de la barre de renfort (12) dans le trou de forage. L'invention propose aussi une méthode d'installation d'une barre de renfort (12) dans un trou de forage.The invention provides a centering device (10) intended to be mounted on a reinforcing bar (12) of the rebar type before the insertion of the reinforcing bar (12) in a borehole, characterized in that 'it comprises two half-shells (16, 18) intended to be fixed one on the other by enclosing a section (20) of the reinforcing bar (12), each half-shell (16, 18) comprising fixing elements (22) cooperating with complementary fixing elements (24) arranged on the other half-shell (16, 18), and each half-shell (16, 18) comprising a centering member (34) provided for come into contact with the internal wall of the borehole after insertion in order to ensure the centering of the reinforcing bar (12) in the borehole. The invention also provides a method of installing a reinforcing bar (12) in a borehole.
