The anchor design

The anchor design

vhi manufactures round bar anchors for refractory installations with diameters of between 4 and 12 mm. Various versions of anchors satisfy the requirements of different applications and types of mounting. Whilst the connector of the anchoring to the steel casing of the component part is able to absorb considerable force, special attention must be paid to the transmission of retention forces into the refractory concrete.

The corrugation of the anchor is decisive in this respect, by which we mean the depth of corrugation in relation to the diameter of the anchor. The corrugation of anchoring manufactured by vhi is usually 1.0 d. Where special demands are placed on the mounting, we recommend corrugation of 1.5 d or the use of anchors with double corrugation. The angle of spread is generally 80 °. This can be changed for longer installation lengths in order to maintain a small distance between anchor ends. This takes place either using a smaller angle of spread along the entire installation length or using a smaller angle in the lower part with a wider angle at the upper end of the anchor.
