(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 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, austenitic ferritic stainless steel, 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 referred to in 5.2.1 as there are no known regulated requirements for products of this family for non-structural use.
Festlegungen für Ergänzungsbauteile für Mauerwerk - Teil 3: Lagerfugenbewehrung aus Stahl
Spécifications pour composants accessoires de maçonnerie - Partie 3: Treillis d'armature en acier pour joints horizontaux
La présente Norme européenne spécifie les exigences concernant les armatures 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 des treillis employés comme armatures 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, d'acier inoxydable austéno-ferritique, de tôle d'acier pré-galvanisé ou de fil d'acier galvanisé, avec ou sans revêtement organique.
NOTE Étant donné l'absence d'exigences réglementaires connues pour les produits de cette famille destinés à un usage non structurel, l'Annexe ZA fait uniquement référence aux treillis en fils soudé destinés à un usage structurel tel qu'indiqué en 5.2.1.
Specifikacija za dodatne komponente zidovja - 3. del: Jeklene mreže za armiranje naležnih reg
Ta evropski standard določa zahteve za armiranje naležnih reg zidovja za konstrukcijsko (5.2.1) in nekonstrukcijsko uporabo (5.2.2).
Za izdelke, namenjene za uporabo v zidu z votlino, ta evropski standard zajema samo delovanje mrež kot armature v naležnih regah in ne njihovega delovanja kot zidnih stremen v votlini.
Ta evropski standard se ne uporablja za:
a) izdelke, kot so posamezne palice ali drogovi;
b) izdelke iz materialov, ki se razlikujejo od podanih vrst avstenitnega nerjavnega jekla, avstenitnega feritnega nerjavnega jekla, pocinkane jeklene plošče ali pocinkane jeklene žice z organsko prevleko ali brez nje.
OPOMBA: Dodatek ZA se nanaša samo na varjene žičnate mreže, ki so namenjene za konstrukcijsko uporabo kot v 5.2.1, saj ni znanih drugih predpisanih zahtev za izdelke iste družine za nekonstrukcijsko uporabo.
