Festeankere

Festeankere is a term used in the field of anchorage engineering to denote a class of anchor devices designed to secure structural elements to a substrate. The name combines elements meaning “to fix” and “to anchor,” and it is used in contexts where reliable attachment is required for long‑term stability.

A festeankere typically consists of an anchor body, a fixation mechanism (expanding, mechanical locking, or chemical grout), a load‑transfer interface, and a protective coating. Materials commonly used include stainless steel, alloy steel, and high‑strength composites, chosen for strength and corrosion resistance. Many designs are modular to accommodate different load ratings, substrate types, and installation constraints.

Installation involves selecting a suitable borehole, positioning the anchor, and actuating the mechanism to develop bite or expansion, followed by sealing or grout where required. Performance is assessed through design calculations and, where mandated, load testing. Releasable variants are used for temporary works; permanent variants provide long‑term resistance to tension and shear, with considerations for creep and environmental exposure.

Festeankere are used in construction, retrofit projects, seismic reinforcement, offshore platforms, and mining support schemes. They offer high load capacity, good adaptability to different substrates, and, for some designs, reversible installation. Limitations include substrate quality requirements, potential corrosion, installation complexity, and cost. Proper inspection and adherence to relevant standards are essential.
