Timber structures - Glued laminated timber and glued laminated solid timber - Requirements
This European Standard specifies the requirements for glued laminated timber for use in load bearing structures. It also specifies the requirements for large finger joints in the glued laminated timber. This European Standard specifies the requirements for glued laminated timber produced from untreated timber or from timber treated against biological attack.
Holzbauwerke - Brettschichtholz und Balkenschichtholz - Anforderungen
Diese Europäische Norm legt die Leistungsanforderungen und die Mindestanforderungen an die Herstellung von Brettschichtholz, Balkenschichtholz, Verbundbauteilen aus Brettschichtholz und Universal-Keilzinkenverbindungen in Brettschichtholz zur Verwendung im Hochbau und im Brückenbau fest.
Die Anforderungen müssen ergänzt werden, um besondere Herstellungsbedingungen, Baustoffe oder Anforderungen an die Funktion zu berücksichtigen.
Diese Europäische Norm gilt für Brettschichtholz aus bestimmten aufgelisteten Nadelholzarten oder aus Pappel mit mindestens zwei Lamellen mit einer Dicke zwischen 6 mm und 45 mm.
Diese Europäische Norm gilt für Balkenschichtholz aus bestimmten aufgelisteten Nadelholzarten oder aus Pappel mit zwei oder drei Lamellen mit einer Dicke über 45 mm, jedoch weniger als oder gleich 85 mm. Die maximale Höhe von Balkenschichtholz beträgt 240 mm, die maximale Breite beträgt 280 mm.
Diese Europäische Norm gilt für Verbundbauteile aus Brettschichtholz mit massivem rechteckigem Querschnitt.
Die Festlegungen dieser Europäischen Norm gelten für Universal-Keilzinkenverbindungen in Bauteilen aus Brettschichtholz mit einer Zinkenlänge von mindestens 45 mm.
Diese Europäische Norm legt Anforderungen an Brettschichtholz aus unbehandeltem Holz oder aus Holz, das gegen biologischen Befall behandelt wurde, fest. Mit Feuerschutzmittel behandeltes Brettschichtholz ist nicht Gegenstand dieser Norm.
Structures en bois - Bois lamellé-collé et bois massif reconstitué - Exigences
La présente Norme européenne spécifie les exigences de performance et les exigences minimales relatives à la fabrication de bois lamellé-collé, de bois massif reconstitué, d'éléments collés constitués de composants en bois lamellé-collé et d'aboutages à entures de grandes dimensions dans des éléments en bois lamellé-collé, destinés à être utilisés dans les bâtiments et les ponts.
Ces exigences devront être complétées pour prendre en compte des conditions particulières de fabrication, des matériaux particuliers ou des exigences fonctionnelles particulières.
La présente Norme européenne est applicable au bois lamellé-collé fabriqué à partir de certaines essences de bois de résineux énumérées ou de peuplier, constitué de deux lamelles ou plus, ayant une épaisseur comprise entre 6 mm et 45 mm.
La présente Norme européenne est applicable au bois massif reconstitué fabriqué à partir de certaines essences de bois de résineux énumérées ou de peuplier, constitué de deux ou trois lamelles ayant une épaisseur supérieure à 45 mm et inférieure ou égale à 85 mm. La hauteur maximale du bois massif reconstitué est de 240 mm et sa largeur maximale de 280 mm.
La présente Norme européenne est applicable aux éléments collés constitués de composants en bois lamellé-collé de sections transversales rectangulaires massives.
Les spécifications de la présente Norme européenne sont valables pour les aboutages à entures de grandes dimensions réalisés dans des éléments en bois lamellé-collé, avec une longueur d'enture d'au moins 45 mm.
La présente Norme européenne spécifie les exigences relatives aux éléments collés produits à partir de bois non traité ou de bois traité contre les attaques biologiques. Les éléments collés traités par des produits ignifuges ne sont pas couverts.
