Prefabricated reinforced components of lightweight aggregate concrete with open structure
This European Standard is for prefabricated reinforced components of lightweight aggregate concrete (LAC) with open structure intended to be used in building constructions.
Vorgefertigte bewehrte Bauteile aus haufwerksporigem Leichtbeton
Diese Europäische Norm gilt für vorgefertigte Bauteile aus haufwerksporigem Leichtbeton (LAC) und mit
statisch anrechenbarer oder nicht anrechenbarer Bewehrung, die für die Verwendung in Gebäuden
vorgesehen sind für

⎯ tragende Wandbauteile (massiv, mit Hohlräumen im Kern oder mehrschichtig);
⎯ Bauteile für Stützwände (massiv) mit oder ohne Auflast;
⎯ Dachbauteile (massiv, mit Hohlräumen im Kern oder mehrschichtig);
⎯ Deckenbauteile (massiv, mit Hohlräumen im Kern oder mehrschichtig);
⎯ stabförmige Bauteile (Balken oder Pfeiler).
b) Nichttragende Bauteile:
⎯ nichttragende Wandbauteile (z. B. für 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.
ANMERKUNG 1 Zusätzlich zu ihrer tragenden und raumabschließenden Funktion können die Bauteile auch für
Zwecke des Brandschutzes, der Schalldämmung und der Wärmedämmung verwendet w
Bauteile nach dieser Europäischen Norm sind nur für den Einsatz unter vorwiegend ruhenden Lasten
bestimmt, sofern nicht in den diesbezüglichen Abschnitten dieser Norm besondere Maßnahmen vorgesehen
werden.
Der Ausdruck „bewehrt“ schließt die statisch anrechenbare Bewehrung und die statisch nicht anrechenbare
Bewehrung ein.
Diese Europäische Norm befasst sich nicht mit
⎯ Anwendungsregeln für diese Bauteile in Bauwerken;
⎯ Fugen (außer mit ihrem Tragwiderstand);
⎯ Befestigungsmitteln;
⎯ Oberflächenausbildung bei Außenbauteilen, wie z. B. eine Verfliesung.
ANMERKUNG 2 LAC-Bauteile können in Schallschutzwänden verwendet werden, wenn sie so bemessen sind, dass
sie auch die Anforderungen von EN 14388 erfüllen.

¾ cadres enterrés de petites dimensions utilisés pour constituer des caniveaux techniques ;
¾ éléments pour écrans antibruit.
NOTE 1 Outre leur fonction porteuse et d'encloisonnement, les éléments peuvent également être utilisés pour les
besoins de la résistance au feu, de l’isolation acoustique et de l’isolation thermique.
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 :
¾ les règles pour l'utilisation de ces éléments dans les ouvrages ;
¾ les jonctions (excepté leur résistance) ;
¾ les accessoires de fixation ;
¾ les finitions, telles que le carrelage, pour les éléments extérieurs.
NOTE 2 Les éléments en LAC peuvent être utilisés dans les écrans antibruit s'ils sont conçus pour satisfaire
également aux exigences de l'EN 14388.

EN 1520:2011 (E) 7 Foreword This document (EN 1520:2011) has been prepared by Technical Committee CEN/TC 177 “Prefabricated reinforced components of autoclaved aerated concrete or lightweight aggregate concrete with open structure”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2011, and conflicting national standards shall be withdrawn at the latest by December 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1520:2002. Among others, the following changes have been made compared to EN 1520:2002: terms and definitions have been updated; the order of clauses has been changed; lightweight aggregate concrete parameters have been adapted; normative references for reinforcement steel have been updated; properties and requirements of components have been adapted, e.g. acoustic properties, thermal resistance; evaluation of conformity has been adapted; Annex A and Annex ZA have been adapted; the standard has been editorially edited. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 89/106/EEC. For relationship with EU Directives, see informative Annex ZA, which is an integral part of this document. This document uses the methods given in the Guidance Paper L, clause 3.3, of the European Commission. This European Standard is used together with a national application document. The national application document may only contain information on those parameters which are left open in this European Standard for national choice, known as Nationally Determined Parameters, to be used for the design of the construction products and civil engineering works to be constructed in the country concerned, i.e.: values and/or classes where alternatives are given in this European Standard; values to be used where a symbol only is given in this European Standard; country specific data (geographical, climatic, etc.), e.g. snow map; the pr
