Brief introduction
The ACI 318 rebar Coupler works together with upset forging machine(GD-150) and rebar threading machine(GZL-45) for the connection of rebar whose diameter is between 12mm and 40mm.
As an important parallel thread connection technology, the upset forging parallel thread connection technology posses following advantage:

1,Wide working range: adaptable for Φ12mm-Φ50mm same diameter, different diameter,
bending, new and old, advance covered up rebar of GB 1499, BS 4449, ASTM A615 or ASTM A706 standard.
2,High strength: stronger than the reinforcement bar and guarantees bar break under tensile stress(tensile strength of connection point =1.1 times of connected bar).It can satisfy the requirements stipulated in the Chinese standard JGJ107-2003,JG171-2005.
3,High efficiency: upset forging and threading one joint only needs no more than one minute, and handy operation and quick link.
4,Environmental protection and economy profit: no environment pollution, can work all day, not affected by weather, economize energy source and bar material.

Working principle:
First, we use GD-150 to forge the end of rebar.
Second, we use the GZL-45 to thread the end of rebar.
Third, we use the ACI 318 rebar Coupler to link the two ends of rebar.
