A new re-usable modular concrete construction formwork having both edge ribs and transverse ribs each made of two walls parallel one to the other and perpendicular to the panel of the formwork. Between the parallel walls are various plates parallel one to the other and preferably perpendicular to the walls of the rib and to the panel. The ribs are disposed along the perimeter, and transversally to the panel. Further ribs, of smaller height, diagonally cross the square or rectangular areas delimited by the edge ribs and the transversal ribs. In correspondence to the crossing of two or more main transversal ribs and/or edge ribs, the ribs are shaped as a circle or as a portion of circle. Centrally in said circular shaped area of the ribs, the panel of the formwork includes a hole for the passing of the iron containing rod. On the edge ribs there are holes for the insertion and the closure of the closing keys.
L'invention porte sur un nouveau coffrage modulaire réutilisable muni de nervures latérales et de nervures transversales, lesquelles sont faites de deux parois parallèles entre elles et perpendiculaires au panneau du coffrage. Lesdites parois parallèles circonscrivent un jeu de plaques parallèles entre elles et préférablement perpendiculaires aux parois de la nervure et du panneau. Les nervures sont disposées sur le pourtour et orientées transversalement par rapport au panneau. D'autres nervures plus petites disposées en diagonale dans les surfaces carrées ou rectangulaires sont délimitées par les nervures latérales et les nervures transversales. Aux endroits où elles traversent deux nervures transversales principales ou plus et/ou deux nervures latérales ou plus lesdites nervures adoptent une forme circulaire ou représentant une partie de cercle. Au centre desdites formes circulaires des nervures, le panneau de coffrage est muni de trous pour laisser passer les tiges d'armature ferreuses. Les nervure latérales sont pour leur part munies de trous pour l'insertion et le verrouillage des clés.
