Finger jointed structural timber - Performance requirements and minimum production requirements
This standard specifies requirements for bonded finger joints and minimum requirements for the manufacture of cut, interlocking, bonded finger joints in structural timber members. Requirements are given for timber, adhesive, moisture content, cutting and bonding.
This standard is only applicable to finger joints between timber members of the same species type.
Although most finger joints are produced in coniferous species this standard also applies to broad-leaved species where information is available to enable them to be satisfactorily bonded.
It does not cover impressed (die-formed) joints. In the case of glued laminated timber it applies only to individual laminations. Large finger joints in glued laminated timber are covered by EN 387.
NOTE This standard is elaborated as a supporting standard for a harmononized standard on structural timber with finger joints to be published in the future.
Keilzinkenverbindungen im Bauholz - Leistungsanforderungen und Mindestanforderungen an die Herstellung
Diese Norm enthält Anforderungen an verklebter Keilzinkenverbindungen und Mindestanforderungen an die Herstellung gefräster, ineinandergefügter und verklebte Keilzinkenverbindungen in Bauholz für tragende Zwecke. Die Anforderungen betreffen das Holz, den Klebstoff, die Holzfeuchte, den Zuschnitt und die Klebung.
Diese Norm gilt nur für Keilzinkenverbindungen in Holzbauteilen derselben Holzart.
Obwohl die meisten Keilzinkenverbindungen aus Nadelholzarten hergestellt werden, gilt diese Norm auch für Laubholzarten, sofern Angaben über Anforderungen, die eine zufrieden stellende Verklebung ergeben, vorliegen.
Verbindungen, deren Zinken durch Pressverformung hergestellt werden, sind in dieser Norm nicht berücksichtigt. Im Falle von Brettschichtholz bezieht sich die Norm nur auf die Keilzinkung einzelner Lamellen. Universal-Keilzinkenverbindungen in Brettschichtholz sind in EN 387 enthalten.
ANMERKUNG Diese Norm wurde als unterstützende Norm für eine harmonisierte Norm für Keilzinkenverbindungen im Bauholz, die zu einem späteren Zeitpunkt veröffentlicht werden soll, erarbeitet.
Aboutages à entures multiples dans les bois de construction - Exigences de performance et exigences minimales de fabrication
La présente norme définit des exigences pour les aboutages à entures multiples collés et les exigences minimales pour l'usinage et l'emboîtement des aboutages à entures multiples collés dans les éléments de bois de structure. Les exigences concernent le bois, les adhésifs, la teneur en humidité, l'usinage, l'encollage et les traitements de préservation.
La présente norme s'applique uniquement aux aboutages à entures multiples entre les membrures en bois de même type d'essence.
Bien que la plupart des aboutages à entures multiples soit produite avec des essences résineuses, la présente norme s'applique aussi aux feuillus, si des informations sont disponibles pour leur permettre de réaliser des assemblages collés satisfaisants.
Elle ne concerne pas les aboutages matricés. Dans le cas de bois lamellés collés, elle s'applique exclusivement aux lamelles individuelles. Les aboutages à entures multiples de grandes dimensions dans les bois lamellés collés sont couverts par l'EN 387.
NOTE La présente norme est élaborée en tant que support à une norme harmonisée sur les bois de structure avec aboutages à entures multiples, qui sera publiée dans l'avenir.
