Precast construction offers numerous benefits to different
stakeholders of the value chain in the construction industry . Precast
elements are usually manufactured under controlled factory
conditions, thus allowing the production of high quality and precision.
PEIKKO BOLTED CONNECTIONS provide fast and safe assemblies of
precast concrete elements further improving the competitiveness of the
precast concrete industry (see figure 1).
HPKM® Column Shoes, combined with HPM® Anchor Bolts or COPRA®
Anchoring Couplers, are used to quickly create moment resisting column
connections (see figure 2). Column shoes are cast into precast concrete
columns, whereas anchor bolts are cast into foundations or other
supporting structures. At construction sites, the columns are erected on
the anchor bolts and adjusted to the desired position by tightening nuts
onto the anchor bolts. After installation, the joint between the column and
the foundation is grouted. At the final stage, the grouted joint acts as a
traditional reinforced concrete section.
