General remarks
Anchoring on the structure
With Anchoring shoe for stair tower
Q ... shear force
Z ... tensile force
Methods for fixing in concrete:
▪
By using a Cone screw B 7cm to fix the anchoring
shoe to an existing suspension point prepared with
Universal climbing cones 15.0 (diameter of hole in
anchoring shoe = 32
mm). Hardwood shim (essen-
tial for ensuring a firm fit) prevents damage to the
concrete (scratch marks).
This fixing method is only possible with anchoring
shoes manufactured from 05/2009 onwards.
▪
With one or two dowels (diameter of hole in anchor-
ing shoe = 18
mm).
Design of the anchoring planes
The load-bearing tower is connected to the Anchoring
shoe for stair tower by scaffold tubes and couplers.
