ANCHORS > Wedge
For simple and economical
The wedge anchor is installed through the
fixture.Torquing draws the cone end of the stud into the expansion clip. The
expansion clip expands and develops a frictional grip with the sidewalls of the hole.
Application of the installation torque draws
the cone end of the stud into the expansion clip. The expansion clip expands and develops a frictional grip with
the sidewalls of the hole. This gives the anchor its resistance to tension loads.

Recommended loads for single anchors with no
infl uencing edge distance or spacings. Loads are calculated using partial safety factors from ETAG 001 and the
characteristic anchor and installation data.
The recommended loads have been calculated using
the partial safety factors for resistances stated in the pending ETA approval and an partial safety
factor for actions of YF= 1.4. The
permissible loads are valid for unreinforced concrete and reinforced
concrete with a rebar spacing s ≥ 15 cm and reinforced concrete with a rebar spacing s ≥ 10 cm if the
rebar = 10
mm or smaller.
The recommended shear loads are based on a single
anchor without infl uencing concrete edges. For shear loads applied close to an edge (c ≤ 10×hef or
60d) concrete edge failure
must be checked per ETAG 001, Annex C, design method
Concrete is considered non-cracked when the tensile
tress within the concrete is σL + σR ≤ 0. In the absence of detailed verifi cation σR = 3 N/mm2 can be
equates the tensile stress within the concrete as a result of external
loads, forces on anchors included).
If spacings or edge distances become smaller than
the characteristic values (i.e. s ≤ scr,N and/or c ≤ ccr,N) a calculation per ETAG 001, Annex C, design
method A must be
performed. For details, see ETA-11/0080
