Abstract (en)
The subject of the invention is a reinforcement member comprising a steel strip (10) which can be reeled up and intended to be incorporated in the concrete. The faces of the steel strip each comprise substantially straight ribs (12) arranged in at least one longitudinal row (R), these ribs being substantially parallel to each other and inclined with respect to the longitudinal direction of the strip. The ribs (12) of one of the faces of the strip are symmetrical with the ribs (12) of the other of the faces of the strip with respect to the mid-plane of the strip parallel to the faces of this strip. The subject of the invention is also a process and a device for manufacturing this reinforcement. <IMAGE>

L'invention a pour objet une armature comprenant un ruban en acier (10) bobinable destiné à être incorporé dans le béton. Les faces du ruban en acier comprennent chacune des nervures (12) sensiblememt rectilignes disposées suivant au moins une rangée (R) longitudinale en étant sensiblement parallèles entre elles et inclinées par rapport à la direction longitudinale du ruban. Les nervures (12) d'une des faces du ruban sont symétriques aux nervures (12) de l'autre des faces du ruban par rapport au plan médian du ruban parallèle aux faces de ce ruban. L'invention a également pour objet un procédé et un dispositif de fabrication de cette armature. <IMAGE>
