These days, theres a significantly more economical way to assemble steel precast columns. The new HALFEN Column Shoe provides a handy solution for connection to foundations or for linking columns together.
The advantage of the pre-fabricated system with screw connection is the quick assembly. The connection is easy to adjust and immediately force-fit so that braces are not required. The system comprises the HCC column shoe and the suitable HAB anchor bolts for the foundation base. The principle: The column shoes are cast in pre-cast columns, the anchor bolts are cast in foundations on site using a drilling pattern. They are joined force-fit by nuts during assembly. As a last step the bottom of the column and remaining recess are filled with non-shrinking mortar.
