The invention relates to a method for producing reticular structures, especially made of metal, and to a device suited therefor. The aim of the invention is to simplify the production of reticular structures so that they can be automatically manufactured. The invention also seeks a method which permits the large scale manufacturing of reticular structures having large dimensions. To these ends, the following steps are used: (1) inserting a reticulated foam preliminary structure into a container that can be opened; (2) infiltrating this structure with a fire-resistant material; (3) hardening the material (4); taking out the hardened fire-resistant material from said container; (5) removing the foam pre-structure; (6) inserting the resulting preheated body into a heat-resistant container; (7) infiltrating the body with a molten metal, and; (8) taking out the resulting body after the molten metal has solidified and removing the fire-resistant material. The device is comprised of a fire-resistant container whose interior is larger than the fire-resistant preheated body.

L'invention concerne un procédé permettant de produire des structures quadrillées, notamment en métal, ainsi qu'un dispositif approprié à cet effet. L'invention vise à simplifier la production de structures quadrillées, de manière à permettre une fabrication automatique. A cet effet, l'invention vise à mettre au point un procédé qui permette de produire des structures quadrillées de grandes dimensions en grosse production. A cette fin, il est prévu les étapes suivantes : (a) introduire une structure préliminaire en mousse réticulée dans un récipient relevable ; (2) infiltrer cette structure avec une matière réfractaire ; (3) solidifier la matière ; (4) sortir la matière réfractaire solidifiée du récipient relevable ; (5) enlever la structure préliminaire en mousse ; (6) introduire le corps préchauffé obtenu dans un récipient résistant aux températures élevées ; (7) infiltrer le corps avec une matière métallique en fusion et (8) sortir le corps obtenu après solidification et enlever la matière réfractaire. Le dispositif comprend un récipient réfractaire, dont l'espace intérieur est plus grand que le corps réfractaire préchauffé.
