Abstract

Poutrelle en béton armé précontraint du type ayant une section en forme de Té composé d'une âme et d'un talon, caractérisée en ce qu'elle comporte sur au moins une partie des flancs de l'âme des crans ouverts sur la face supérieure de la poutrelle, ces crans ayant une faible profondeur par rapport à leur surface. La forme de ces crans, participe au soulèvement de la poutrelle lors de la mise en précontrainte du béton et par conséquent aide au démoulage. Préfabrication de poutrelles en béton précontraint.
