Rebar couplers are used for joining rebars with full tension capacity. The ends of bars to be joined are provided with threads, and the bars are joined using a coupler sleeve that transfers the force on the rebar across the connection.
Rebar couplers are used in reinforced concrete structures to replace normal rebar lap joints. The couplers are also suitable for use in reinforced concrete columns and walls. Each rebar coupler consists of a piece of rebar equipped with a thread and coupler sleeve at the right end as viewed in the direction of installation. In construction joints, rebar couplers can be used to replace all pieces of rebar going through the formwork.
Reinforcement coupler has ETA acceptance ETA 23/0172. Acceptance concern rebar coupler T16, T20, T25, T32 and T40. To acceptance has included tension resistance of static and dynamic loads and fatique resistance with 2.0 E106 load cycles. Also to acceptance has included seismic resistance to couplers with rebars T16, T20 and T25.

A-BEAM® and Anstar’s connection technology form part of the frame system, offering cost-efficiency and flexibility for construction.
Diagonal ties are used in concrete sandwich panels to connect the outer skin with the inner skin through the insulation layer. The ties transfer the self-weight and wind loads of the outer skin to the inner skin.
Fastening plates are used on cast-in-place and prefabricated structures to provide a mounting surface for welding.
Balcony hinges are used to transfer horizontal forces from the balcony to the building frame. The hinged connection enables vertical movement.
Column shoes and anchor bolts are used to connect precast concrete frames to foundations and column extensions.
Anstar has developed bracket and support systems for efficient and affordable construction. The connection parts are easy to install both at the prefabrication factory and on site.
Rebar couplers are used for joining rebars with full tension capacity. The ends of bars to be joined are provided with threads, and the bars are joined using a coupler sleeve that transfers the force on the rebar across the connection.
ADE® and ADK® bracing connections are designed for stabilising the concrete element frame. These connections
are used in the joints between concrete columns and stabilising steel bracings.
