PEC^® Column Shoes are connecting items of precast concrete columns to form fast and safe column connections under heavy loading conditions. PEC^® Column Shoes are a widely approved product for various types of precast columns.

PEC^® Column Shoes are connecting items that are used with PPM^® Anchor Bolts or COPRA^® Anchoring Couplers to create instantly moment-resisting column connections under heavy loading conditions. Column shoes are cast into precast concrete columns, whereas anchor bolts are cast into foundations or other columns. At construction sites, the columns are erected on the anchor bolts and adjusted to the correct level and vertical position by tightening nuts onto the anchor bolts. Finally, the joint between column and base structure is grouted and, at the final stage, the grouted joint acts as a traditional reinforced concrete cross-section.

As soon as the nuts are tightened, the connection is able to resist erection loads. Therefore, temporary bracing is usually not needed. Typically, four column shoes are enough to create a moment-resisting connection. Peikko’s product range also includes accessories for easy installation of column shoes.
