Abstract

La présente invention concerne un support de boîte de dérivation pour fixer une boîte de dérivation, également appelé caisson lumineux, en position pendant le versement de matériau durcissable dans un coffrage. Le support de boîte de dérivation comprend une base et un cadre de fixation. La base est destinée à être fixée au coffrage de manière opérationnelle. Le cadre de fixation est configuré pour s'étendre sur et en prise complémentaire étroite avec la boîte de dérivation lors de l'utilisation pour fixer la boîte de dérivation en position pendant le versement d'un matériau approprié tel que du béton. Le support de boîte de dérivation est également configuré pour être emboîté avec des supports de boîte de dérivation similaires, et est pourvu d'une partie supérieure frangible qui peut être rompue de telle sorte qu'une paire de supports de boîte de dérivation emboîtés peut être utilisée sur une boîte de dérivation ayant une hauteur importante.
