Peikko’s HELKA^® Column Shoes form fast and safe bolted connections between precast concrete columns and foundations, or between precast concrete columns.

HELKA^® Column Shoes, cast into the bottom part of the precast concrete column, are used with HPM^® Rebar Anchor Bolts or COPRA^® Anchoring Couplers, which are cast into the foundation or another column.

By using HELKA^® Column Shoes, a small onsite crew can erect precast columns easily and efficiently and with no need for bracing or welding, minimizing personnel and crane time.

Immediate connections are made simply by accessing the recesses in the column shoes and leveling and tightening the washers and nuts on the anchor bolts. Grouting the open joint between the column and the structure below enables the connection to act as a reinforced concrete structure.

HELKA^® Column Shoes resist significant axial, tensile, compressive and shear forces, and exposure to fire. Four or more are used in one column cross-section depending on the column dimensions and forces involved.

HELKA^® Column Shoes comprise of steel base plates with holes in them for the anchor bolts, and reinforcement steel bars. Available in three standard sizes, 24, 30 and 39, they are designed to connect to the similarly numbered anchor bolts and anchoring couplers.

The cloud-based and free Peikko Designer^® BOLTED CONNECTION software can be used to optimize connections.
