Determination of screw pull out forces from screw thread channels
This document provides a test method for determining the bearing capacity (pull out force) of a connection consisting of a screw in a screw thread channel, which cannot be calculated in accordance with current codes or conventional calculations. This document can be applied to several products, including doors, windows and curtain walling.
This document applies to screw thread channels made out of metal as well as metal screws.
The pull out forces of such connections may already be assessed indirectly with another test method e.g. wind load resistance for doors/windows according to EN 12211 or curtain walling kits according to EN 12179. Additional information with respect to the mechanical performance of connections and direct applications can be determined with the test method described in this document.
Bestimmung der Schraubenausziehkräfte von Schraubgewindekanälen
Dieses Dokument enthält ein Prüfverfahren zur Bestimmung der Tragfähigkeit (Ausziehkraft) einer Verbindung, die aus einer Schraube in einem Gewindekanal besteht, die nicht nach geltenden Normen oder herkömmlichen Berechnungsverfahren berechnet werden kann. Dieses Dokument kann auf mehrere Produkte angewendet werden, einschließlich Türen, Fenster und Vorhangfassaden.
Dieses Dokument gilt für Gewindekanäle aus Metall sowie für Metallschrauben.
Die Ausziehkräfte solcher Verbindungen können bereits indirekt mit einem anderen Prüfverfahren bewertet werden, beispielsweise der Widerstandsfähigkeit gegen Windlast von Türen/Fenster nach EN 12211 oder von Vorhangfassadenbausätze nach EN 12179. Zusätzliche Angaben zur mechanischen Leistung der Verbindungen und zu den direkten Anwendungsbereichen können mit dem in diesem Dokument beschriebenen Prüfverfahren bestimmt werden.
Détermination de la résistance à l'arrachement des vis dans les canaux de vissage
Le présent document fournit une méthode d’essai permettant de déterminer la capacité portante (force d’arrachement) d’une liaison composée d’une vis insérée dans un canal de vissage, qui ne peut pas être calculée selon les codes courants ou avec les calculs habituels. Le présent document peut être appliqué à plusieurs produits, notamment les portes, les fenêtres et les façades rideaux.
Le présent document s’applique aux canaux de vissage en métal ainsi qu’aux vis métalliques.
La résistance à l’arrachement de ces types de liaisons peut déjà être évaluée indirectement avec une autre méthode d’essai, par exemple la résistance à la charge due au vent selon l’EN 12211 pour les portes/fenêtres ou selon l’EN 12179 pour les kits de façades rideaux. La méthode d’essai décrite dans le présent document permet de déterminer des informations additionnelles concernant la performance mécanique des liaisons et les applications directes.
