Mechanische Verbindungen im Metallleichtbau

Abstract

Construction is not possible without joining single parts to components and at the end to the final structure. There exist multifarious kinds of connections whose suitability mainly depends on the characteristic of raw material the structural parts are made of. This article especially deals with joints in metallic light weight structures. Beside the typical connections in metal structures like welding, bolting and riveting in metallic light weight structures further kinds of connections can be found like standing seam, clinch, punch rivet or cartridge fired pin connections. Describing all these single methods would go beyond the scope of this article. That is why only the predominant part of all connections with so called pencil-shaped fastening elements like screwed connections, blind riveted connections and connections with cartridge fired pins will be dealt with. Furthermore the scope of application will be shown, advantages and disadvantages will be compared, the determination of characteristic values or resistance will be shortly explained and advices for calculation and execution will be given

Experimental investigations on the design and execution of shear loaded blind rivet joints in steel lightweight construction

“…by quality assurance tests within the framework of the FPC (Factory Production Control). 2) Only valid for d = 6.4 mm 3) If the thinner part is on the blind side the bearing resistance must be limited by k 1 α b ≤1.5…”

“…Typical application examples of blind rivets in steel lightweight construction are roof and wall cladding as shown in Figure 1. Nevertheless, there is the limiting factor of the lack of design rules according to the standard EN 1993-1-3 [1], which leads in Germany to the requirement of technical approvals (abz/aBG, ETA, ZiE) for blind rivet joints issued by the highest building authority DIBt [2]. They are the result of individual case studies on special joint configurations, which have no general validity and therefore are not transferable to other applications.…”

Extension of the application limits of blind fasteners for joining high‐strength steels in metal lightweight construction

“…Figure 1 shows a typical example of joint design for joining steel sections with blind rivets in high-rack warehouse systems. Short joint dimensions, thin-walled components and one-sided accessibility characterize those joints, where blind rivets as the most common blind fasteners are primarily used [5].…”

Zur Bemessung von Scher‐/Lochleibungsverbindungen mit Blindnieten im Stahlbau

“…B. im Bereich von Fahrtreppen oder Wohncontainern (Bild ) Anwendung. In haben die Verfasser bereits ausführlich über die gängigen Blindniettypen, deren Verarbeitungsprinzipien und Einsatzgebiete im Stahlleichtbau sowie die versuchsgestützte Bemessung gemäß ECCS und deren Defizite berichtet. Umfangreiche experimentelle Untersuchungen aus einem abgeschlossenen AiF‐Projekt 17823BR , welche zur Erarbeitung eines Bemessungsvorschlags für Blindnietverbindungen im Stahlleichtbau führten, wurden hierzu angestrengt.…”
