Groutec is a mechanical splicing system with one threaded end specially designed for the connection of precast concrete elements. It is designed and manufactured in compliance with Eurocode 2, BS 8110, ACI 318, IBC, AASHTO. The rebar connected on the threaded side and the cavity side are of the same diameter. However, Groutec can also be used to make a transition between rebar of different sizes.
Groutec come with two alternative designs namely Groutec L; large tolerance and Groutec S; slim outside diameter. Groutec-L is for large tolerance that aims at easing one’s site operation by allowing a larger axial misalignment tolerance. It allows connection of continuation bars that are not perfectly aligned: Misalignments of up to 12mm for small bars (Ø12-Ø20), up to 20 mm for medium bars (Ø25) and up to 25 mm for large bars (Ø28-Ø40) can be accommodated. Groutec-S is for slim body which allows precasters to create slim columns and panels. Significantly the grout consumption and preparation time will also reduce.
Advantages
Groutec connects two precast elements with no requirement for in situ wet concrete joint. It is compact and economical splicing solution with one threaded end compatible with bartec, fortec, rolltec or griptec type thread. The product can be used with non-shrink grout easily available from major manufacturers. Groutec has been successfully tested with Sika214 from SIKA, Lanko 701 from PAREX-DAVCO, Cemrok EasiFlow from POZAMENT, Conbextra GP from FOSROC and MasterFlow 870 from BASF. The same coupler model can also be used for the connection of different diameters (transition splices).
Applications
Groutec is designed to connect the precast elements wall or column either horizontally and vertically. In horizontal and vertical applications with the Groutec coupler installed in the top element, the connection is achieved by injecting the grout through the inlet pipe. In vertical applications with the Groutec coupler installed in the bottom element, the grout can simply be poured by gravity directly into the coupler cavity.
