Figure B2: General construction rules for Hilti tension anchor HZA-R

Hilti tension anchor HZA-R may be designed for tension forces only.

The tension forces must be transferred via an overlap joint to the reinforcement in the existing structure.

The length of the bonded-in smooth shaft may not be accounted as anchorage.

The transfer of shear forces shall be ensured by appropriate additional measures, e.g. by shear lugs or
by anchors with a European technical assessment (ETA).

In the anchor plate the holes for the Hilti tension anchor shall be executed as elongated holes with the
axis in the direction of the shear force.
If the clear distance between lapped bars exceeds 4 · ϕ, then the lap length shall be increased by the

difference between the clear bar distance and 4 ·ϕ
