Couplers, spigot pins and baseplates for use in falsework and scaffolds - Part 1: Couplers for tubes - Requirements and test procedures
This document places for normal couplings, rotary clutches, shock couplings and parallel couplings, each with friction, fixed: - materials; - constructive requirements; - strength classes with various constructive parameters, including the values for resistances and stiffnesses; - testing; - Valuation; And gives - recommendations for ongoing production control. These couplings are intended for use in temporary constructions, e.g. B. in scaffolding that are built according to EN 12811-1 and in load scaffolding that are built according to EN 12812.
