Reinforcement Continuity Systems
Leviat manufactures three Ancon products which provide continuity of reinforcement across construction joints in concrete.
Ancon Keybox consists of a galvanised steel casing which is dimpled to provide an effective concrete bond. Pre-bent bars are housed within the casing and are enclosed by a protective cover. When the cover is removed the bars can be straightened ready for lapping onto the main reinforcement.
Ancon KSN Anchors with BT threaded reinforcing bars can simplify concrete design at construction joints, typically in wall-to-slab applications. The anchor is cast into the face of the concrete wall. When the formwork and thread protection is removed, the reinforcing bar is screwed into the anchor. Once all other reinforcement is installed, the adjoining slab is cast to complete the installation.
Where the connecting bar is larger than 12mm, continuity of reinforcement can be provided by the installation of an Ancon Coupler Box. These boxes combine standard Keybox casings with the BT mechanical splicing system.
With their new European Technical Assessment (ETA), Halfen HZA serrated anchor channels fulfil all requirements of AS 5216:2021 and can be used in projects across Australia.
Leviat has released an enhanced version of its popular Ancon Shearfix design software that enables engineers to maintain a flat concrete slab at column heads by reinforcing the area against punching shear with a prefabricated, stud-rail system.
