NKK COLUMN SHOE

Exmet’s NKK Column Shoes are gaining traction as a preferred choice for connecting columns to foundations or other columns. Designed to accommodate a variety of connection needs, Exmet offers an extensive selection of column shoes and anchor bolts.

These column shoes have undergone rigorous testing in European laboratories, demonstrating an equivalent rigidity to continuously reinforced CIP connections. NKK Column Shoe and anchor bolt connections establish robust, moment-resisting links between columns and foundations or between columns themselves. The strength of the column shoe connection is determined by the anchoring resistance of the selected anchor bolt. This connection type efficiently resists axial loads, bending moments, shear forces, and combinations thereof.

Exmet provides supplementary products such as casting blocks and installation plates, which facilitate the hassle-free installation of column shoes in precast elements during factory operations and the precise positioning of precast columns at the desired level during on-site erection. Upon grouting, the column shoe and anchor bolt combination creates a sturdy, moment-resisting joint between columns or between a column and its foundation.

NKK Column Shoes are particularly suitable for connections under moderate load conditions and can be obtained with plain or hot-dip galvanized surface coatings upon request.

Among various benefits, the key advantages of NKK Column Shoes include:

  • Effortless connection through bolted assembly
  • Accelerated erection and adjustable connection
  • Swift transfer of erection forces upon column erection and bolting
  • Erection without temporary bracing or extra support
  • Stiff and robust connection
  • Convenient availability in Exmet’s stock
