Abstract

L'invention concerne un procédé, des fondations de machine sur plaque d'assise et/ou une utilisation qui permettent de réaliser des fondations de machine sur plaque d'assise (38) dans un délai de construction plus court. A cet effet, selon le procédé de l'invention, le béton (42) est coulé en place sur au moins un élément semi-fini en béton (12) placé dans sa position définitive dans les fondations de machine sur plaque d'assise (38). Dans les fondations de machine sur plaque d'assise (38) de l'invention, la plaque d'assise (40) est constituée d'au moins un élément semi-fini en béton (12) et d'un béton (42) coulé en place sur l'élément semi-fini en béton (12). L'utilisation proposée selon l'invention consiste à se servir dudit au moins un élément semi-fini en béton (12) pour réaliser une plaque d'assise (40) dans des fondations de machine sur plaque d'assise (38).
