Selon l'invention, la machine vibrante comprend un bâti de base, un dispositif de production de vibrations, une table vibrante qui peut être mise en vibration par le dispositif de production de vibrations et sur laquelle le moule à béton destiné à la formation de pièces moulées en béton peut être mis en place, des éléments permettant le couplage du moule à béton et de la table vibrante pour limiter les bruits. L'invention a pour objet la mise au point d'un moule économique pour la réalisation de blocs de pierre composites et d'une machine vibrante qui, tout en conservant sa puissance ou pour une puissance améliorée, a un niveau sonore significativement réduit et impose des vibrations limitées à son environnement. L'invention concerne un procédé de réalisation d'un bloc de pierre composite comprenant une première plaque composée de pierre naturelle ou d'un matériau analogue à la pierre naturelle, la plaque étant reliée à un noyau de béton. Selon le procédé, pour permettre la réalisation du bloc de pierre composite, ladite plaque est introduite dans un moule à béton, puis une masse de composite est appliquée sur la plaque puis recouverte de béton, de préférence de béton brut à consistance de terre humide. Le béton brut est compacté dans une machine vibrante qui comprend un bâti de base, un dispositif de production de vibrations, une table vibrante qui peut être mise en vibration par le dispositif de production de vibrations et sur laquelle le moule à béton destiné à la formation du bloc de pierre composite peut être mis en place, des éléments permettant le couplage du moule à béton et de la table vibrante pour limiter les bruits. Les éléments de couplage correspondent à un système de couplage par dépression grâce auquel, au cours du processus de mise en vibration, une dépression provoque une attraction par liaison de force entre la table vibrante et le moule à béton.
