Prefabricated reinforced components of autoclaved aerated concrete
Prefabricated reinforced components of autoclaved aerated concrete
This European Standard is for prefabricated reinforced components of autoclaved aerated
concrete to be used in building construction for:
a) Structural elements:
. load-bearing wall components (solid or multilayer);
. retaining wall components;
. roof components;
. floor components;
. linear components (beams and piers).
b) Non-structural elements:
. non-loadbearing wall components (partition wall components);
. cladding components (without fixtures) intended to be used for facades of buildings;
. small box culverts used to form channels for the enclosure of services;
. components for noise barriers.
Depending on the type and intended use of elements for which the components are utilised, the
components can be applied - in addition to their loadbearing and encasing function - for purposes of
fire resistance, sound insulation and thermal insulation in the relevant clauses of this European
Standard.
Components covered by this standard are only intended to be subjected to predominantly non-dynamic
actions, unless special measures are introduced in the relevant clauses of this European Standard.
The term "reinforced" relates to reinforcement used for both structural and non-structural purposes.
This European Standard does not cover:
. rules for the application of these components in structures;
. joints (except their strength);
. fixtures;
finishes for external components, such as tiling.
Vorgefertigte bewehrte Bauteile aus dampfgehärtetem Porenbeton
Diese Europäische Norm gilt für vorgefertigte bewehrte Bauteile aus dampfgehärtetem Porenbeton, die für die Verwendung in Gebäuden vorgesehen sind für:
a) tragende Bauglieder:
- tragende Wandbauteile,
- Bauteile für Stützwände,
- Dachbauteile,
- Deckenbauteile,
- stabförmige Bauteile (Balken und Pfeiler);
b) nicht tragende Bauglieder:
- nicht tragende Wandbauteile (Trennwände),
- Bauteile für Verkleidungen (ohne Befestigungsmittel), die zur Befestigung an den Außenfassaden von Gebäuden bestimmt sind,
- kleine kastenförmige Hohlquerschnitte, die zur Herstellung von Kanälen zur Aufnahme von Versorgungsleitungen dienen,
- Bauteile für Lärmschutzwände.
Je nach der Art und dem vorgesehenen Verwendungszweck der Bauglieder, für welche die Bauteile eingesetzt werden, können die Bauteile - zusätzlich zu ihrer tragenden und Raum abschließenden Funktion - für Zwecke des Brandschutzes, der Schalldämmung und der Wärmedämmung entsprechend den diesbezüglichen Abschnitten dieser Europäischen Norm verwendet werden.
Bauteile nach dieser Europäischen Norm sind nur für den Einsatz unter vorwiegend ruhenden Lasten bestimmt, sofern nicht in den diesbezüglichen Abschnitten dieser Europäischen Norm besondere Maßnahmen vorgesehen werden.
Der Ausdruck "bewehrt" schließt Bewehrung für tragende und nicht tragende Zwecke ein.
Diese Europäische Norm befasst sich nicht mit:
- Anwendungsregeln für diese Bauteile in Bauwerken;
- Fugen (außer ihres Tragwiderstands und der Unversehrtheit E bezüglich des Feuerwiderstands);
- Befestigungsmitteln;
- der Oberflächenausbildung bei Außenbauteilen, wie z. B. eine Verfliesung.
ANMERKUNG Bauteile aus dampfgehärtetem Porenbeton dürfen in Lärmschutzwänden verwendet werden, wenn sie so bemessen sind, dass sie auch die Anforderungen von EN 14388 erfüllen.
Eléments préfabriqués armés en béton cellulaire autoclavé
La présente Norme européenne s’applique aux éléments préfabriqués armés en béton cellulaire autoclavé destinés a etre utilisés pour la construction de bâtiments en :
a) éléments structuraux :
- éléments de murs porteurs (pleins ou multicouches) ;
- éléments de murs de soutenement ;
- éléments de toiture ;
- éléments de plancher ;
- éléments linéaires (poutres et trumeaux).
b) éléments non structuraux :

- éléments de bardage (sans supports de montage) destinés a etre utilisés pour les façades externes des bâtiments ;
- cadres enterrés de petite dimension utilisés pour former des canaux pour les gaines d'équipement ;
- éléments pour écrans antibruit.
Selon le type et l'usage prévu des installations pour lesquelles les éléments sont utilisés, ces derniers peuvent s'appliquer – en plus de leur fonction de portance et d'enrobage – pour les besoins de la résistance au feu, l'isolation acoustique et l'isolation thermique dans les articles appropriés de la présente Norme européenne.
Les éléments couverts par la présente norme sont uniquement destinés a etre soumis a des actions a prédominance non dynamique, sauf si des mesures particulieres sont présentées dans les articles appropriés de la présente Norme européenne.
Le terme « armé » comprend tout type d'armature a but structural et non structural.
La présente Norme européenne ne couvre pas :
- les regles pour l'utilisation de ces éléments dans les structures ;
- les joints (excepté leur résistance et leur étanchéité E de résistance au feu) ;
- les supports de montage ;
- les finitions pour éléments externes, tels que le carrelage.
NOTE Les éléments en BCA (béton cellulaire autoclavé) peuvent etre utilisés dans les écrans antibruit s'ils sont conçus pour satisfaire également aux exigences du prEN 14388.
