These couplers are intended for use in temporary works equipment for example in scaffolds erected in accordance with EN 12811 1 and falsework erected in accordance with EN 12812.

Kupplungen, Zentrierbolzen und Fußplatten für Arbeitsgerüste und Traggerüste - Teil 1: Rohrkupplungen - Anforderungen und Prüfverfahren

Dieses Dokument legt für Normalkupplungen, Drehkupplungen, Stoßkupplungen und Parallelkupplungen, jeweils mit Reibschluss, fest:
—   Werkstoffe;
—   konstruktive Anforderungen;
—   Festigkeitsklassen mit verschiedenen konstruktiven Parametern, einschließlich der Werte für Widerstände und Steifigkeiten;
—   Versuchsdurchführung;
—   Bewertung;
und gibt
—   Empfehlungen für die laufende Produktionskontrolle.
Diese Kupplungen sind für den Einsatz in temporären Konstruktionen vorgesehen, z. B. in Arbeitsgerüsten, die nach EN 12811 1 errichtet werden, und in Traggerüsten, die nach EN 12812 errichtet werden.

Raccords, goujons d’assemblage et semelles pour étaiements et échafaudages - Partie 1 : Raccords de tubes - Exigences et modes opératoires d’essai

Le présent document spécifie, pour les raccords orthogonaux, les raccords à angle variable, les raccords de prolongation et les raccords parallèles travaillant par friction :
- les matériaux ;
