(Main)Timber structures - Product requirements for prefabricated structural members assembled with punched metal plate fasteners
Timber structures - Product requirements for prefabricated structural members assembled with punched metal plate fasteners
This European Standard specifies material, product and documentation requirements for prefabricated structural members (e.g. trusses for roofs, walls and floors, frames, composite beams and girders) for use in buildings made from solid structural timber according to EN 14081-1 with or without finger joints assembled with punched metal plate fasteners.
The standard also covers tests and/or calculation methods to carry out the evaluation of conformity and requirements for the marking of these members.
As regards resistance to biological organisms, this standard covers prefabricated structural members manufactured from either untreated timber or timber treated to improve its natural durability.
This standard does not cover prefabricated timber structural members intended to be used in constructions under predominantly dynamic loads (e.g. bridges) or for use in unprotected external conditions (i.e. use class 3 in accordance with EN 335-1).
Furthermore, it does not cover members treated to improve their fire performance.
Holzbauwerke - Produktanforderungen an vorgefertigte tragende Bauteile mit Nagelplattenverbindungen
Diese Europäische Norm legt die Werkstoff-, Produkt- und Dokumentationsanforderungen an vorgefertigte tragende Bauteile (z. B. Fachwerkträger für Dächer, Wände und Decken sowie Rahmen, Verbundbalken und Träger) fest, die aus Bauvollholz nach EN 14081-1 mit oder ohne Keilzinkenverbindungen unter Verwendung von Nagelplatten gefertigt werden und die für die Verwendung in Gebäuden bestimmt sind.
Dieses Dokument gilt für Fachwerkträger mit Längen bis 35 m und für weitere vorgefertigte tragende Bauteile mit Spannweiten bis 12 m.
Diese Norm enthält auch Prüf- und/oder Berechnungsverfahren zur Durchführung der Konformitätsbeurteilung, Kennzeichnung dieser Bauteile und zu Bedingungen im Freien (Nutzungsklasse 3 nach EN 1995-1-1 oder Gebrauchsklasse 3, 4 und 5 nach EN 335-1).
Bezüglich der Widerstandsfähigkeit gegen biologische Organismen behandelt diese Norm vorgefertigte tragende Bauteile, die entweder aus unbehandeltem Holz hergestellt sind, oder aus Holz, das behandelt wurde, um seine natürliche Haltbarkeit zu verbessern.
Diese Norm behandelt keine vorgefertigten tragenden Bauteile, die zur Verwendung in Anlagen unter vorwiegend dynamischen Belastungen (z. B. für Brücken) oder unter ungeschützten Bedingungen im Freien (d. h. Gebrauchsklasse 3 nach EN 335-1) vorgesehen sind.
Ebenso nicht enthalten sind Bauteile, die behandelt wurden, um das Verhalten im Brandfall zu verbessern.
Structure en bois - Exigences de produit relatives aux éléments de structures préfabriqués utilisant des connecteurs à plaque métallique emboutie
La présente norme spécifie les exigences de matériau, de produit et de documentation relatives aux éléments
de structure préfabriqués (par exemple, fermes pour toits, murs et planchers, cadres, poutres et poutrelles
composites) destinés à être utilisés dans des bâtiments fabriqués à partir d’éléments en bois de structure
conformément à l’EN 14081-1 avec ou sans aboutages à entures multiples, assemblés au moyen de
connecteurs à plaque métallique emboutie.
Ce document est valable pour les fermes de longueur jusqu’à 35 m et pour d’autres éléments préfabriqués de
structure avec des portées jusqu’à 12m.
Cette norme traite également des méthodes d’essai et/ou de calcul servant à l’évaluation de la conformité,
des exigences pour le marquage de ces éléments, et des conditions extérieures (classe de service 3 selon
EN 1995-1-1 ou classes d’emploi 3,4 et 5 selon EN 335-1).
En ce qui concerne la résistance vis à vis des organismes biologiques, la présente norme traite des éléments
de structure préfabriqués soit à partir de bois non traité, soit à partir de bois traité afin d’améliorer sa durabilité
naturelle.
La présente norme ne traite pas des éléments de structure préfabriqués en bois destinés à être utilisés dans
des constructions soumises de manière prédominante à des charges dynamiques (par exemple des ponts) ou
pour une utilisation dans des conditions extérieures non protégées (c’est à dire classe d’emploi 3 selon l’EN
335-1).
De plus, la norme ne couvre pas les éléments traités afin d’améliorer leur performance au feu.
Lesene konstrukcije - Zahteve za proizvodnjo predhodno izdelanih konstrukcijskih elementov s kovinskimi ježastimi ploščami
Ta evropski standard določa zahteve glede materiala, proizvodov in dokumentacije za proizvodnjo predhodno izdelanih konstrukcijskih elementov (npr. nosilnih tramovov za strehe, stene in tla, okvirjev, sestavljenih gredi in tramov) za uporabo v stavbah, ki so izdelani iz trdnega konstrukcijskega lesa v skladu z EN 14081-1 z ali brez spojev z zobci, s kovinskimi ježastimi ploščami. Ta dokument se uporablja za nosilne tramove dolžin do 35 m in za druge predhodno izdelane konstrukcijske elemente z razponi do 12 m. Standard zajema tudi metode za preskušanje in/ali izračun za izvedbo ocene skladnosti, zahteve za označevanje teh elementov in zunanje pogoje (razred storitve 3 v skladu z EN 1995-1-1 ali razredi uporabe 3, 4 in 5 v skladu z EN 335-1). Glede odpornosti proti biološkim organizmom ta standard zajema predhodno izdelane konstrukcijske elemente iz bodisi neobdelanega lesa ali lesa, ki je obdelan zaradi izboljšanja njegove naravne trajnosti. Ta standard ne zajema predhodno izdelanih lesenih konstrukcijskih elementov, namenjenih za uporabo pri konstrukcijah pod pretežno dinamičnimi obtežbami (tj. mostovih) ali za uporabo v nezaščitenih zunanjih pogojih (tj. razred uporabe 3 v skladu z EN 335-1). Poleg tega ne zajema elementov, ki so obdelani zaradi izboljšanja njihove požarne odpornosti.
