This threaded rebar coupler is belong to Upset forging parallel thread connection system, different from our standrad coupler, one end of rebar coupler is concave, which can meet different project requirements.
Working principle:
First, use GD-150 Upset forging machine to enlarge the end of rebar.
Secong, use GZL-45 Threading machine to process screw on the enlarged end.
Third, use one rebar coupler to connect two rebar ends.
Advantages of the technology:
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.
