1)
The permissible loads apply for the design method II (unknown lowest load and unknown load
cycles). The partial safety factor for material resistance and the partial safety factor for action
regarding fatigue as regulated in the approval are considered. When using design method I higher
permissible loads may be possible. As an single anchor counts e.g. an anchor with a spacing s ≥
3 x h ef and an edge distance c ≥ 1,5 x h ef . Accurate data see approval.
2)
Minimum possible axial spacings resp. edge distance while reducing the permissible load.
3)
For combinations of tensile loads, shear loads as well as reduced edge distances or spacings
(anchor groups) see approval.
4)
For higher concrete strength classes up to C50/60 higher permissible loads may be possible.
6)
The given loads are valid for fixations in dry and humid concrete for temperatures in the substrate
up to +50°C (resp. short term up to 80°C) and best possible drillhole cleaning according approval.
