EN 845-3:2003+A1:2008
(Main)Specification for ancillary components for masonry - Part 3: Bed joint reinforcement of steel meshwork
Specification for ancillary components for masonry - Part 3: Bed joint reinforcement of steel meshwork
This EN specifies the requirements for welded wire meshwork, woven wire meshwork and expanded metal meshwork for use as reinforcement in bed joints of masonry. Where products are intended for use in cavity wall construction, this European Standard covers only the performance of the meshwork as reinforcement in bed joints and not its performance as wall ties across the cavity.
Festlegungen für Ergänzungsbauteile für Mauerwerk - Teil 3: Lagerfugenbewehrung aus Stahl
Diese Europäische Norm legt die Anforderungen an Lagerfugenbewehrung für Mauerwerk für Konstruktionen mit Bemessung (siehe 5.2.1) sowie für Konstruktionen ohne Bemessung (siehe 5.2.2) fest.
Für Produkte zur Verwendung in zweischaligem Mauerwerk wird in dieser Europäischen Norm lediglich das Verhalten von Stahldrahtgittern als Bewehrung in Lagerfugen, nicht jedoch das Verhalten als Luftschichtanker behandelt.
Diese Norm gilt nicht für:
a) Produkte in Form einzelner Flach- oder Rundstäbe;
b) Produkte, die nicht aus austenischem rostfreien Stahl der festgelegten Güte, Stahlblech mit Zink- Vorbeschichtung oder verzinktem Stahldraht mit oder ohne organischen Überzug bestehen.
ANMERKUNGDer Anhang ZA bezieht sich nur auf geschweißte Stahldrahtgitter für tragende Zwecke für die in 5.2.1 genannten Verwendungszwecke, da keine gesetzlich geregelten Anforderungen an Produkte dieser Familie für Konstruktionen ohne Bemessung bekannt sind.
Spécification pour composants accessoires de maçonnerie - Partie 3: Treillis d'armature en acier pour joints horizontaux
La présente Norme européenne spécifie les prescriptions concernant les treillis d'armature pour les joints
horizontaux de maçonnerie à usage structurel (voir 5.2.1) et non-structurel (voir 5.2.2).
Dans le cas où les produits sont destinés à être utilisés dans la construction de murs doubles, la présente Norme
européenne couvre uniquement les performances du treillis employé comme armature pour les joints horizontaux
et ne s’applique pas aux performances du treillis utilisé comme attache pour mur double traversant la cavité.
Les produits suivants ne sont pas couverts par la présente Norme européenne :
a) produits sous forme de barres ou de tiges individuelles ;
b) produits fabriqués à partir de matériaux autres que les classes spécifiées d'acier inoxydable austénitique, la tôle
d'acier pré-galvanisé ou le fil d'acier galvanisé, avec ou sans revêtement organique.
NOTE L’Annexe ZA fait uniquement référence aux treillis d’armature en fils soudés destinés à un usage structurel, traité
en 5.2.1, car il n’y a pas d’exigences réglementées connues qui s’appliquent aux produits de cette famille destinés à un usage
non structurel.

1 Scope
This European Standard specifies the requirements for masonry bed joint reinforcement for structural
use (see 5.2.1) and for non-structural use (see 5.2.2).
Where products are intended for use in cavity wall construction, this European Standard covers only
the performance of the meshwork as reinforcement in bed joints and not its performance as wall ties
across the cavity.
This European Standard is not applicable to:
a) products in the form of individual bars or rods;
b) products formed from materials other than specified grades of austenitic stainless steel or zinc
pre-coated steel sheet or zinc coated steel wire with or without organic coating.
NOTE Annex ZA refers only to welded wire meshwork intended for structural use for structural use referred
to in 5.2.1 as there are no known regulated requirements for products of this family for non.structural use.
