Prefabricated reinforced components of lightweight aggregate concrete with open structure
This European Standard is for prefabricated reinforced components of lightweight aggregate concrete with open structure intended to be used in building constructions: a) for structural elements: - loadbearing wall components (solid, hollow core and multilayer); - retaining wall components (solid) with or without surcharge loading; - roof components (solid, hollow core and multilayer); - floor components (solid, hollow core and multilayer); - linear components (beams and piers).
Vorgefertigte bewehrte Bauteile aus haufwerksporigem Leichtbeton
Diese Europäische Norm ist eine Produktnorm für vorgefertigte bewehrte Bauteile aus haufwerksporigem Leichtbeton. Bei der Verwendung der Bauteile müssen die wesentlichen Anforderungen der Bauproduktenrichtlinie erfüllt sein.Der Zweck der Norm ist es, eine standardisierte Dokumentation der Bauteileigenschaften zu ermöglichen. Die Eigenschaften sind die für die Verwendung der Bauteile maßgebenden Informationen (Festigkeit, Steifigkeit, Rohdichte, Maße usw.).
Produits préfabriqués armés en béton de granulats légers a structure ouverte
La présente Norme européenne traite des éléments préfabriqués armés en béton de granulats légers a structure ouverte, destinés a etre utilisés dans la construction de bâtiments :
a) comme éléments structuraux :
éléments de murs porteurs (pleins, alvéolés ou multicouches) ;
éléments de murs de soutenement (pleins), avec ou sans surcharge ;
éléments de toiture (pleins, alvéolés et multicouches) ;
éléments de plancher (pleins, alvéolés et multicouches) ;
éléments linéaires (poutres ou poteaux) ;
b) comme éléments non structuraux :
éléments de murs non porteurs (par exemple: cloisons) ;
éléments de bardages (sans fixations) destinés a etre utilisés en façades de bâtiments ;
petits caissons pour constituer des caniveaux techniques ;
éléments de murs antibruit.
Selon le type et l'utilisation prévue de parties constitutives réalisées avec de tels éléments, ces derniers peuvent etre employés - outre leur fonction porteuse ou de façade - pour assurer des fonctions de résistance au feu, d'isolation acoustique et d'isolation thermique, selon les articles correspondants de la présente Norme européenne.
Les éléments traités dans cette norme sont seulement destinés a supporter des actions prédominantes non dynamiques sauf si des mesures particulieres sont incluses dans les articles correspondants de la présente Norme européenne.
Le terme " armé " concerne aussi bien les armatures utilisées a des usages structuraux que les armatures non structurales.
La présente Norme européenne ne traite pas :
des regles d'application de ces éléments dans des structures ;
des joints (a l'exception de leur résistance) ;
des fixations ;
des finitions des éléments extérieurs tels que carrelages.
