These days, there is a significantly more economical way to
assemble precast columns. The new HALFEN Column Shoe provides a
handy solution for connection to foundations or for linking columns
The advantage of the pre-fabricated system with screw connection is
the quick assembly. The connection is easy to adjust and
immediately loadable so that bracing is not required. The system
comprises of 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 by load bearing nuts during assembly. As a
last step the bottom of the column and remaining recess are filled
with non-shrinking mortar.
Installation of the HALFEN anchor bolts
The anchor bolts must be installed exactly according to the
location and arrangement shown in the design drawings. It is
expedient to use a mounting template; this will help to firmly and
accurately fix the anchor bolts on the formwork, so that they do
not move during installation of the reinforcement or during the
pouring and compaction of the concrete.
HALFEN column shoes are connecting parts that form rigid column
connections and column stacks in heavily stressed structures. The
rigid connection is effective both in the mounting state and in the
final state. The forces on the HALFEN anchor bolts HAB H (head
bolts) or HAB S (rod anchor) are transferred into the base
The wide range of products covers a wide range of load levels in
order to realize as many installation situations as possible.
HALFEN HAB H anchor studs are made of concrete steel B 500 B with
The anchoring is achieved through a unilaterally forged head (head
HAB H anchor studs are, due to their low installation depth,
especially suitable for anchoring in flat structures such as the
foundations or walls that have sufficiently large edge distances.
HAB S rod anchors, however, are more suitable for thicker
structures with sufficient anchoring length. In this case the edge
distances can be reduced.
