Anchor bolt steels
Anchor bolt steels are manufactured in hot rolling mills (by quenching, cold-drawing or additional tempering, alone or in combination) in straight lengths. The steel rod surface is ribbed or threaded.
The anchor bolt acts as a tension member, resisting the forces exerted by the tie anchor locks at either end. In scaffolds, the anchor bolts are used temporarily.
Anchor bolt steels are suitable for use as anchor bolts for formwork ties (DIN 18216) and as components of Scaffold anchors.
Regulatory framework
DIBt grants national technical approvals (abZ) for anchor bolt steels.
Please also note the applicable design and execution rules, cf. in particular MVV TB, Part A 1.
DIN 18216:1986-12: Formwork ties; requirements, testing, use
Section 3.1 of the following document contains information on the application of the Guideline for approval-related and external surveillance testing of prestressing steels (Richtlinie für Zulassungs- und Überwachungsprüfungen für Spannstähle) in relation to formwork ties:
