Application Technology of Half Grouting Rebar Coupler

Half grouting rebar coupler is a important type of grouting connection, which is used to connect vertical steel bars of prefabricated concrete components, such as the connection of main bars of prefabricated shear walls, prefabricated frame columns, and prefabricated decorative panels. One end of the half grouting rebar coupler is mechanically connected to the steel bar and the other end is a grouting cavity, which is anchored with the steel bar through the grouting material.

JM-GT series half grouting rebar coupler are grouting connection sleeves with straight threads, it including GT4 (connecting with HRB400 steel bars), GT5 (connecting with HRB500 steel bars) grouting rebar coupler. In addition, there are HG-type half grouting rebar coupler specially used for export, and the diameter of connecting steel bars ranges from 12mm to 40mm.

Application Technology of Grouting Sleeve

Grouting connection means that both ends of the grouting sleeve are cavities, which are connected to the steel bars through the grouting material. It is suitable to the connection of the horizontal main bars between the beams and the connection of the main bars of the vertical members.

Grouting sleeves are divided into GTH series vertical grouting sleeves and GTQ4J series beam grouting sleeves. In addition, there are FG series vertical grouting sleeves and FGS series beam grouting sleeves specially designed for export.

The diameter of the grouting sleeve connecting the steel bars ranges from 16mm to 40mm.
