(Main)Steel for the reinforcement of concrete - Weldable reinforcing steel - General
Steel for the reinforcement of concrete - Weldable reinforcing steel - General
1.1 This document specifies general requirements and definitions for the essential characteristics of weldable reinforcing steel used for the reinforcement of concrete structures, delivered as finished products in the form of:
- bars (including those produced by the reinforcing steel manufacturer from coil);
- coils;
- sheets of factory-made machine-welded fabric;
- lattice girders.
1.2 Steels according to this document have a ribbed, indented or smooth surface.
NOTE 1 The protrusions between indentations of indented reinforcing steel have the same function as transverse ribs of ribbed reinforcing steel. There is no definition which specifies the difference between ribbed and indented surface geometry. Therefore, in this document, the same bond parameters are used for ribbed and indented steel.
1.3 This document does not apply to:
- non-weldable reinforcing steel;
- galvanized reinforcing steel;
- epoxy-coated reinforcing steel;
- corrosion resistant reinforcing steel;
- prestressing steels;
- indented strip;
- further processing by a processor, e.g. de-coiling/straightening, cutting or cutting and bending.
NOTE 2 Further processing could influence some essential characteristics of the product.
Stahl für die Bewehrung von Beton - Schweißgeeigneter Betonstahl - Allgemeines
1.1 Dieses Dokument legt allgemeine Anforderungen und Definitionen für die Leistungsmerkmale von schweißgeeignetem Betonstahl fest, der für die Bewehrung von Betonbauwerken verwendet und als Fertigerzeugnis geliefert wird in Form von:
- Stäben (einschließlich bei dem Stahlhersteller vom Ring abgewickelten Erzeugnissen);
- Ringen;
- werkmäßig gefertigten maschinell geschweißten Matten;
- Gitterträgern.
1.2 Stähle nach diesem Dokument haben eine gerippte, profilierte oder glatte Oberfläche.
ANMERKUNG 1 Die Erhebungen zwischen zwei Vertiefungen bei profiliertem Betonstahl haben die gleichen Funktionen wie die Schrägrippen bei geripptem Betonstahl. Daher gibt es keine Sonderdefinition mit dem Unterschied der geometrischen Merkmale zwischen dem gerippten und profilierten Betonstahl. Die in diesem Dokument enthaltenen Festlegungen für den Verbund gelten für gerippten und profilierten Betonstahl.
1.3 Dieses Dokument gilt nicht für
- nicht schweißgeeigneten Betonstahl;
- verzinkten Betonstahl;
- epoxibeschichteten Betonstahl;
- korrosionsbeständigen Betonstahl;
- Spannstahl;
- profiliertes Band;
- Weiterverarbeitung, z. B. abwickeln / richten, schneiden oder schneiden und biegen.
ANMERKUNG 2 Die Weiterverarbeitung kann manche Leistungsmerkmale des Erzeugnisses beeinflussen.
Aciers pour l'armature du béton - Aciers soudables pour béton armé - Généralités
1.1 Le présent document énonce les définitions et exigences générales relatives aux caractéristiques essentielles des aciers pour béton armé soudables utilisés pour l’armature des structures en béton, livrés comme produits finis sous forme de :
- barres (y compris celles produites par le producteur d’acier pour béton armé à partir de bobines) ;
- bobines ;
- panneaux de treillis soudé par machine en usine ;
- treillis raidisseurs.
1.2 Les aciers dans le présent document ont une surface à verrous ou empreintes ou lisse.
NOTE 1 Les reliefs entre les empreintes des aciers pour béton armé à empreintes ont la même fonction que les verrous transversaux des aciers pour béton armé à verrous. Aucune définition ne précise la différence entre les géométries des surfaces à verrous et à empreintes. Par conséquent, dans le présent document, les paramètres d’accrochage utilisés pour les aciers à verrous et à empreintes sont les mêmes.
1.3 Le présent document ne s’applique pas aux :
- aciers pour béton armé non soudables ;
- aciers pour béton armé galvanisés ;
- aciers pour béton armé recouverts d’époxyde ;
- aciers pour béton armé résistants à la corrosion ;
- aciers pour armatures de précontrainte ;
- feuillards crantés ;
- transformations ultérieures par un transformateur - comme le déroulage/dressage, la coupe à longueur ou la coupe et façonnage.
NOTE 2 Les transformations ultérieures sont susceptibles de modifier certaines caractéristiques essentielles du produit.
