ABSTRACT:
A re-usable modular formwork comprising at least one panel having edge ribs and transversal ribs, each of the ribs comprising two parallel walls perpendicular to the formwork panel and preferably perpendicular to the walls of the rib and to the panel. Said ribs are disposed along the perimeter of the panel and transversally to the panel. Other ribs of smaller height may be positioned diagonally within the square or rectangular areas delimited by the edge ribs and the transversal ribs. Where two or more main transversal ribs and/or edge ribs intersect, these ribs have rounded joints. Centrally in said rounded joints, there is an opening for introducing a containing rod. Other openings may be present on the edge ribs for inserting and locking closing keys.
