AHK® Column Shoe
The connection consists of a prefabricated shoe that is installed in the element formwork before casting. The shoe connection is in working order when its grouting concrete has reached the design strength. Shoe connection design is made easy and fast with A-COLUMN® design software. The bolts used for the shoes are ATP and AHP® rebar bolts.
AHK shoes are used in office, commercial and public buildings for connecting light concrete element frames to foundations and for column extensions. The shoes are also suitable for connecting concrete columns to the foundations of industrial buildings. The product is tested and rated to withstand demanding building conditions and is manufactured in accordance with SFS-EN 1090-2:2018.
AHK® column shoes are used in light- and heavy-duty column extension and foundation connections of concrete frames, in corner connections of rectangular columns.
AHK®-K middle shoes are for use in the middle of the sides of rectangular columns and in round columns.
AHK-K® shoes are middle shoes used in the middle of rectangular columns’ sides or in wall-like elements in connections transferring normal and shear forces as well as bending moment. AHK-K® shoes are also suitable for round columns, since their bonds are optimally located at the surface of a round column’s stirrups. The shoes are used for extending columns and connecting them to foundations. A connection with two shoes only transfers normal force, and a connection with 4–8 shoes transfers normal and shear forces as well as bending moment.
