Different Mechanical Splicing Methods of Rebar

Type A:

When the connecting bar can be rotated.                     

Consisting of 2 standard threads and 1 coupler.

The first bar is fully engaged inside the coupler (at the production line).

The assembly is completed by rotating the connecting inside the coupler 

until full engagement.          

       

Type B:

When the connecting bar is too long or too heavy to turn.

Consisting of 1 standard thread,1 left hand thread,1 right-and-left thread 

coupler. The two bars are placed in position,The assembly is completed by 

turning the wrench until full engagement.

 

 

Type C:

When the connecting bars have different diameters.

Consisting of 2 standard thread and 1 different diameter coupler.

The first bar is fully engaged inside the different diameter coupler

(at the production line).

The assembly is completed by rotating the connecting bar inside the coupler until full engagement.

 

Type W:  Weldable ( connected with steel column)

Consisting of 1 standard thread and 1 weldable coupler

A weldable coulper is welded onto a steel member.

The assembly is completed by rotating the connecting bar inside the coupler until full engagement.
