Abstract

Dispositif de formation de vide à appliquer sur la tête d'une ancre de levage noyée pour un composant en béton coulé. Ledit dispositif comprend deux parties de corps aptes à venir en prise avec la tête de l'ancre pour enserrer ladite tête. Ledit dispositif comprend en outre des moyens définissant au moins une zone prédéterminée dans une paroi supérieure du dispositif de formation de vide pour l'insertion d'un outil de retrait à l'intérieur dudit dispositif. Ledit dispositif comprend enfin des moyens définissant une zone prédéterminée à l'intérieur pour l'engagement d'une extrémité de l'outil, ce qui permet à l'outil d'être utilisé pour tirer le dispositif de formation de vide hors de la tête suite au coulage.
