Abstract

L'invention a pour objet un élément d'armature pour plafond à nervures en béton coulé comprenant au moins un élément de déplacement (6), en particulier en mousse, placé entre une armature de principe et une armature de répartition. Cet élément de déplacement est adjacent à des cavités (7, 7') afin de former des nervures de renfort et fixé de manière immuable entre les armatures au moyen de fils jointifs reliant l'armature de principe à l'armature de répartition avec un écart pouvant être sélectionné, pour former une unité indéformable. Des éléments d'armature relevée (8, 8') supplémentaires sont placés dans les cavités nervurées et chaque élément de déplacement fait partie d'un corps en treillis autonome (1) avec une partie d'armature de principe (3) et une armature de répartition (4). Le corps en treillis est disposé sur une armature de base (2) incorporée dans une plaque (12) en béton coulé avec une partie d'armature de principe du corps en treillis et des parties des éléments d'armature relevée. Une membrure supérieure en béton (13), parallèle aux cavités nervurées, de longueur, largeur et hauteur pouvant être sélectionnées, est placée au centre sur l'armature de répartition du corps en treillis ou d'au moins un des corps en treillis.
