KS Threaded Anchors

The use of Ancon KS Threaded Anchors with Bartec 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.

This system eliminates the need to drill either formwork or concrete. It replaces cogged or hooked bar ends simplifying bar scheduling and can be used to minimise congestion in the wall.

Alternatively, the Ancon KS Anchor can be used to provide a high capacity fixing point for a standard metric bolt.

System Components

KS Threaded Anchor
The KS Threaded Anchor is machined from solid bright drawn steel bar. The head is hot forged. It complies with AS3600 (2001), whereby the area under the anchor head must be at least ten times the cross-sectional area of the reinforcing bar for it to be considered fully anchored.

Threaded Bar
KS Anchors are designed for use with 12mm and 16mm grade 500 reinforcing bar, threaded with a Bartec metric thread. The Bartec system produces a full strength joint. The bar end is cut square and enlarged by cold forging. This increases the core diameter of the bar to ensure that the joint is stronger than the bar. Parallel metric threads are cut onto the enlarged ends. The threaded ends are protected by an external plastic sheath. An M16 thread is cut onto an 12mm bar and an M20 on an 16mm bar. Standard lengths, 40 times the bar diameter, are held in stock. The maximum bar length is 6000mm.

Performance data for this system is given in the 'KS Threaded Anchors' brochure available to download here.
