Reinforcement Continuity Systems

Reinforcement Continuity Systems

Leviat manufactures six Ancon products which provide continuity of reinforcement at slab-to-wall construction joints in concrete.

KSN Anchors

The KSN system comprises internally-threaded anchors which are cast into the wall and, during construction of the adjoining slab, accept continuation bars prepared with a Bartec parallel-thread.

There is no on site bar straightening and virtually no restriction on bar length, so EC2 lap lengths are easily accommodated. A standard timber carrier allows multiple anchors to be installed simultaneously. Unlike re-bend systems where bar length, spacing and diameter are restricted by physical box dimensions, KSN Anchors provide total design flexibility.

KSN Anchor Box

Our internally threaded KSN Anchors, supplied in a metal casing and used in combination with Bartec Plus parallel-threaded reinforcing bars, can be detailed in a single row along the slab section centreline at slab-to-wall connections subjected to a combination of shear and tensile loads.

CB Coupler Box

Ancon CB Coupler Boxes simplify the continuity of reinforcement at concrete construction joints. They allow engineers to design slab-to-wall connections without the traditional restrictions on bar length and bar diameter of re-bend/pull-out continuity systems and help contractors to eliminate manual bar straightening on site.

CS Coupler Strip

Ancon CS Coupler Strips offer all the benefits of the CB Coupler Box above and are specifically designed to simplify rebar continuity at joints where walls are curved on plan. A flexible steel strip with integral Ancon couplers is nailed directly to curved shuttering.

Starter Bar System

Ancon Starter Bars are supplied fixed to an Ancon coupler. Once cast in concrete, the coupler’s end cap is removed and a threaded continuation bar is installed with a calibrated torque wrench to complete the connection.

Eazistrip Rebend System

Ancon Eazistrip consists of pre-bent bars housed within a galvanised steel casing. Once installed, the protective cover is removed and the bars are straightened.
