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:
- loadbearing wall components;
- retaining wall components;
- roof components;
- floor components;
- linear components (beams and piers).
b) Non-structural elements:
- nonloadbearing wall components (partition walls);
- cladding components (without fixtures) intended to be used for external 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 indicated 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 and integrity E of resistance to fire);
- fixtures;
-  finishes for external components, such as tiling.
NOTE AAC components may be used in noise barriers if they are designed to fulfil also the requirements of EN 14388.

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)   nichttragende Bauglieder:
—   nichttragende 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 raumabschließenden Funktion — für Zwecke des Brandschutzes, der Schalldämmung und der Wärmedämmung entsprechend den diesbezüglichen Abschnitten dieser Europäischen Norm verwendet werden.
Bauteile nach dieser Norm sind nur für den Einsatz unter vorwiegend ruhenden Lasten bestimmt, sofern nicht in den diesbezüglichen Abschnitten dieser Europäischen Norm besondere Maßnahmen vorgesehen werden.

Les éléments couverts par la présente norme sont uniquement destinés à être soumis à des actions principalement statiques, sauf si des mesures particulières sont présentées dans les articles appropriés de la présente Norme européenne.
Le terme « armé » se rapporte à tout type d'armature à but structural et non structural.
La présente Norme européenne ne couvre pas :
-   les règles pour l'utilisation de ces éléments dans les ouvrages ;
-   les jonctions (excepté leur résistance mécanique et leur étanchéité E en termes de résistance au feu) ;
-   les accessoires de fixation ;
-   les finitions,  tels que le carrelage, pour éléments extérieurs.
NOTE   Les éléments en béton cellulaire autoclavé (AAC) peuvent être utilisés dans les écrans antibruit s'ils sont conçus pour satisfaire également aux exigences de l'EN 14388.

Montažni armirani elementi iz avtoklaviranega celičnega betona

Ta evropski standard se uporablja za montažne armirane elemente iz avtoklaviranega celičnega betona, ki bodo uporabljeni za naslednje: a) Gradbeni elementi: – komponente za nosilne zidove; – komponente za oporne zidove; – strešne komponente; – talne komponente; – linearne komponente (tramovi in stebri). b) Negradbeni elementi: – komponente za nenosilne zidove (pregradne stene); – obložne komponente (brez priključkov), ki se uporabljajo za zunanje fasade stavb; – majhne škatlaste nosilce, ki tvorijo kanale za ohišje storitev; – komponente za hrupne pregrade. Glede na vrsto in predvideno uporabo elementov, za katere se komponente uporabljajo, je mogoče komponente uporabiti – poleg njihove nosilne in obdajne funkcije – za namene požarne odpornosti, zvočne izolacije in toplotne izolacije, kot je navedeno v ustreznih točkah tega evropskega standarda. Komponente, ki jih zajema ta standard, se lahko izpostavljajo predvsem nedinamičnim vplivom, razen če so v ustreznih točkah tega evropskega standarda predstavljeni posebni ukrepi. Izraz »armirani« je povezan z armaturo, ki se uporablja za gradbene in negradbene namene. Ta evropski standard ne zajema: – pravil za uporabo teh komponent v konstrukcijah; – spojev (razen njihove trdnosti in integritete E za požarno odpornost); – priključkov; – apretur za zunanje komponente, kot so ploščice. OPOMBA: elementi iz avtoklaviranega celičnega betona se lahko uporabljajo pri protihrupnih ovirah, če so zasnovani tako, da izpolnjujejo tudi zahteve standarda EN 14388.
