1) The recommended loads have been calculated using the characteristic capacities stated in the ETA-assessment with the partial safety factors given in the ETAG001 and the partial safety factor for loads: f = 1.4.
2) The recommended axial loads are valid for unreinforced concrete and reinforced concrete with a rebar spacing s ≥ 15 cm (any diameter) or with a rebar spacing s ≥ 10 cm, if the rebar diameter is 10 mm or smaller.
3) The figures for shear are based on a single anchor without influence of concrete edges. For anchorages close to edges (c ≤ max [10 hef; 60d]) the concrete edge failure shall be checked per
ETAG 001, Annex C, design method A.
4) Concrete is considered non-cracked when the tensile stress within the concrete is \sigmaL + \sigmaR ≤ 0. In the absence of detailed verification \sigmaR = 3 N/mm² can be assumed ( \sigmaL equals the tensile
stress within the concrete induced by external loads, anchors loads included).
6) The recommended bending moment is only valid for threaded rods.

Installation

In these systems, the interior of the armature is pulled into the expansion sleeve and the sleeve is pressed against the borehole wall. This creates friction between the wellbore and the ever expanding anchor. This principle of action is reliable and allows a high load on the anchor.

Drill the hole

Dusting off the hole

Set the anchor through the fixture

Apply installation torque
