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.

The EN 385:2001 standard provides an essential framework for the performance requirements and minimum production requirements for finger jointed structural timber. This comprehensive standard specifies the necessary conditions and stipulations for producing bonded finger joints, which are critical in ensuring the integrity and strength of structural timber members. One of the strengths of EN 385:2001 lies in its detailed scope, which includes specifications not only for the timber and adhesive used but also the moisture content, cutting, and bonding processes. This thorough approach ensures that all aspects of finger joint manufacturing are covered, allowing for consistent quality and reliability in the construction industry. The standard’s applicability to both coniferous and broad-leaved species enhances its relevance in various contexts, extending the usability of finger joints across different timber types. The inclusion of guidelines for bonding methodologies is particularly beneficial for manufacturers aiming to create cross-species finger joints, promoting versatility in materials selection. Furthermore, the standard recognizes the limitations of its scope, specifically excluding impressed (die-formed) joints and focusing solely on individual laminations in glued laminated timber. This clarity helps stakeholders in the timber supply chain understand the specific applications of EN 385:2001 and reinforces its purpose as a supporting standard for future harmonized standards related to structural timber with finger joints. Overall, EN 385:2001 stands out for its rigorous demand for quality control and its ability to facilitate reliable finger joints in structural timber, making it an indispensable resource for manufacturers and professionals in the timber construction field.
EN 385:2001は、指接合構造木材に関する性能要件と最小生産要件を定めた規格です。この規格の範囲は、構造木材部材における接着された指接合の要件と、カットされた、かみ合う、接着された指接合の製造に関する最小要件を指定しています。具体的には、木材、接着剤、含水率、カットおよび接着に関する要件が含まれています。 この規格の強みは、同種の木材部材間の指接合に適用される点で、特に針葉樹が主に使用される一方で、広葉樹にも適用可能であることです。これにより、さまざまな木材タイプに対応できる柔軟性があります。さらに、指接合の品質を確保するための具体的な要件が明確に定義されているため、製造業者や設計者にとって信頼性の高い基準となっています。 EN 385:2001は、接着された指接合に関する最小生産要件を提供し、将来発表される構造木材に関する調和規格のサポート標準としての役割も果たします。このように、この規格は構造木材業界において非常に重要であり、品質確保のための基盤を提供しています。また、個別のラミネーションに対する要件を提示することで、グルーラム製品における製造プロセスの信頼性を高めることに寄与しています。全体として、EN 385:2001は、指接合構造木材の性能と製造に関する重要な指針を提供する非常に有用な標準と言えます。
SIST EN 385:2002 표준 문서는 접합 나무 구조물의 성능 요건 및 최소 생산 요건을 명시하는 중요한 기준입니다. 이 표준은 구조용 목재 부재의 붙이기 된 엄지손가락 접합에 대한 요건을 설명하며, 목재, 접착제, 수분 함량, 절단 및 접합과 같은 필수 요소들에 대한 구체적인 요구 사항을 제공합니다. 이 표준의 강점은 동일한 종의 나무 부재 간의 엄지손가락 접합에만 적용된다는 점과, 대엽 종에서도 접합이 가능하다는 정보를 제공한다는 것입니다. 일반적으로 침엽수에서 많이 사용되지만, 문서에는 폭넓은 종류의 나무에 대한 정보가 포함되어 있어 접합 품질을 보장하는 데 기여합니다. 이는 고유한 재료의 특성과 접착제를 최대한 활용하여 고품질 구조물 구현에 중요한 요소입니다. 또한, 이 표준은 금형이 적용된 접합에는 적용되지 않으며, glued laminated timber에서는 개별 레미에만 적용됩니다. 이는 생체의 복잡성과 구조적 안정성을 고려하는 데 있어 중요한 범위를 설정합니다. EN 385:2001 표준은 향후 발표될 구조용 나무와 엄지손가락 접합에 대한 조화로운 표준의 지원 기준으로서의 역할을 할 예정입니다. 이러한 점에서 이 문서는 목재 산업의 발전과 안전성을 향상시키는 데 필수적인 표준이라고 할 수 있습니다.
