Thread Rebar Splice Coupling Steel Reinforced Thread Bar Coupler for Rebar Connection
Usage
Steel Reinforced Coupler for Rebar Connection is designed to produce a full strength mechanical joint between reinforcing bars, replacing the need for lap splicing.
Features
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.
Specification
1. Material: Aisi 1045 High quality carbon steel.
2. Use: to splice rebar dia 12--50mm.
3. High strength, low cost, simple operation.
