1. Manufactured with advanced casting technology, the grouted sleeves are equipped with intricate internal structures including ribs and stoppers to improve grout flowability and structural strength.

2. Fabricated from ductile iron, Cheeron grout couplers achieve a tensile strength Rm ≥ 550 MPa, percentage elongation after fracture ≥ 5%, nodularity ≥ 85%, and hardness ranging from 180 to 250 HBW.

3. Grout coupler applications: main types of load-bearing rebar connections in precast elements. Grout coupler is applicable for splicing rebars with diameters ranging from 12 mm to 40 mm in prefabricated composite concrete structures.

4. They are classified into fully-grouted rebar couplers and semi-grouted rebar couplers .

Grout coupler advantage

• Semi-grout sleeve : In the component factory, grout coupler is necessary to process the steel bar threads

• Whole grout sleeve : No need to process the steel bar threads in the component factory, making construction more convenient.

The applications specifically include the connections for:

Longitudinal load-bearing reinforcement in precast columns and precast beams.

Vertical reinforcement in precast shear walls.

Grouted splice coupler can also be utilized for splicing vertical and horizontal rebar in Cast-in-Place (CIP) structures during the refurbishment or reconstruction of existing buildings (Existing Structure Retrofitting).

For the splicing of load-bearing rebar in vertical precast elements, either semi-grouted sleeves or fully-grouted sleeves may be utilized.

For the connection of longitudinal load-bearing reinforcement in horizontal precast elements at the Cast-in-Place (CIP) closure strip, fully-grouted sleeves can be employed.
