The BESISTA® rod anchors are used to connect tension rods to gusset plates. The anchors are made of top-grade, highly ductile EN-GJS-400-18-LT spheroidal graphite cast iron, with guaranteed notched bar impact work at –20 °C. This cast iron is particularly suitable for these components.
The 100% control of the thread screw-in depth by means of inspection holes is a unique feature of the BESISTA® rod anchors. This obviates the need for the cover sleeves required by other rod systems to ensure an adequate screw-in depth.
Filigree ribs on the BESISTA® rod anchors and the smooth transitions from the straps to the shaft guarantee perfect forming and casting while at the same time serving as wrench flats to prevent wear of the designer contours. The ribs around the inspection hole make up for the cross-sectional area lost due to the hole.
The wrench flats on the tension rods, used in conjunction with those on the rod anchors serving as a counterholder, allow simple tensioning of the rod systems. Particularly by tensioning from both sides at the same time, high tensile strengths can be achieved by hand without distorting either the rod systems or gusset plates.
The patented specially designed internal straps on the BESISTA® rod anchors allow axial offsets of up to 2°. This largely prevents transverse stresses and protects coatings – a major benefit during installation.
