Mechanical Rebar Splicing System

Code: MRS16

Konsa mechanical rebar splicing couplers join reinforcing bars in tension or compression applications without threading or special bar-end preparation. The coupler fits over plain or deformed bars and uses lock-shear bolts to grip the reinforcement; the bolt heads shear at the designed installation torque. The system offers a practical solution where conventional lap splicing is difficult or congested. Select the coupler size that matches the rebar diameter in the specification table.

Weldable Half Couplers

Code: WHC16

Konsa weldable half couplers create a mechanical rebar connection point on structural steel members such as piles, weld plates, beams and columns. The steel connector is welded to the supporting member, after which the reinforcing bar is secured using the integrated lock-shear bolts. A 45-degree chamfer supports preparation of the welded joint. Select the coupler size for the rebar diameter and ensure the weld detail is specified and completed by suitably qualified personnel.

Threaded Rebar Splicing System

Code: MTC16

Konsa threaded rebar splicing couplers join reinforcing bars with parallel threads as an alternative to lap splices. Available in sizes MTC16 to MTC40 for selected bar diameters; confirm thread form and bar preparation with the project specification.

Rebar Pull-Out Box System

Code: POB150140

Konsa rebar pull-out boxes create planned reinforcement continuity between concrete pours in walls, stairs, slabs, balconies and other staged construction. The galvanised steel box has an interlocking lid and pre-bent Grade 500S pull-out bars. After the first pour and formwork removal, the lid is opened, the bar legs are straightened and lapped into the next reinforcement zone. Multiple bar diameters, centres, lap lengths and box widths are available, with custom and stainless-steel versions on request.
