Timber structures - Cross laminated timber - Requirements
This document specifies the requirements for cross laminated timber with rectangular cross-sections shaped by sawing, planning or other methods.
This document covers cross laminated timber, untreated or treated against biological attack.
This document does not cover timber treated by fire retardant products.
Holzbauwerke - Brettsperrholz - Anforderungen
Diese Europäische Norm legt die Leistungsanforderungen und die Mindestanforderungen an die Herstellung der folgenden Brettsperrholzprodukte zur Verwendung im Hochbau und im Brückenbau fest, die Maßabweichungen nach dieser Norm aufweisen:
a) Brettsperrholz;
b) Brettsperrholz mit Universal Keilzinkenverbindungen.
Darüber hinaus enthält die Norm Festlegungen zur Konformitätsbewertung und Kennzeichnung von Brettsperrholzprodukten.
Diese Europäische Norm gilt für Brettsperrholzprodukte aus den in dieser Norm aufgelisteten Nadelholzarten mit mindestens drei rechtwinklig zueinander verklebten Lagen. Je nach Anzahl der Lagen dürfen aneinandergrenzende Lagen parallel zur Faser verklebt werden. Bauholzlagen bestehen aus Bauholz, das entsprechend EN 14081 1 nach Festigkeit sortiert ist und die in dieser Norm festgelegten Maße aufweist.
Diese Europäische Norm gilt auch für Brettsperrholzprodukte mit Lagen aus Holzwerkstoffen.
In dieser Europäischen Norm sind Anforderungen an ebene und gekrümmte Produkte aus Brettsperrholz festgelegt.
Die Festlegungen dieser Europäischen Norm gelten für Brettsperrholzprodukte mit Universal Keilzinkenverbindungen mit einer Keilzinkenlänge von mindestens 45 mm, die ausschließlich aus Bauholzlagen bestehen und zwischen den verbundenen Bauteilen keine regelmäßige Änderung der Faserrichtung aufweisen.
Darüber hinaus legt diese Europäische Norm Anforderungen an Brettsperrholzprodukte fest, die gegen biologischen Befall behandelt wurden. Mit Feuerschutzmittel behandelte Brettsperrholzprodukte sind nicht Gegenstand dieser Norm.
Diese Europäische Norm deckt Brettsperrholz zur Verwendung entsprechend der Nutzungsklasse 1 oder Nutzungsklasse 2 ab.
Structures en bois - Bois lamellé croisé - Exigences

b) bois lamellé croisé avec aboutages à entures multiples de grandes dimensions.
Elle établit également des dispositions concernant l’évaluation de la conformité et le marquage de produits en bois lamellé croisé.
La présente Norme européenne est applicable aux produits en bois lamellé croisé fabriqués à partir des essences de bois de résineux énumérées dans la présente norme et constitués d’au moins trois couches collées orthogonalement. En fonction du nombre de couches, les couches contigües peuvent être collées parallèlement au fil. Les couches de bois sont constituées de bois classé selon la résistance conformément à l’EN 14081-1 et dont la taille est conforme aux spécifications de la présente Norme.
La présente Norme européenne est également applicable aux produits en bois lamellé croisé comprenant des couches de panneaux à base de bois.
La présente Norme européenne définit les exigences pour les produits en bois lamellé croisé plans et courbes.
Les spécifications de la présente Norme européenne sont valables pour les produits en bois lamellé croisé avec des aboutages à entures multiples ayant une longueur d’enture d’au moins 45 mm, constitués exclusivement de couches de bois pour lesquelles le sens du fil ne change pas régulièrement d’un composant à l’autre.
La présente Norme européenne spécifie également les exigences relatives aux produits en bois lamellé croisé traités contre les attaques biologiques. Les produits en bois lamellé croisé traités par des produits ignifuges ne sont pas couverts.
La présente Norme européenne couvre le bois lamellé croisé destiné à être utilisé dans la classe de service 1 ou 2.
