- the deformed rebar fixing washer (8) first puts the deformed rebar fixing washer (8) in the female coupler housing (4) or the mail coupler housing (5) when assembling the first and second stage high strength rebar couplers. Next, the coupler body (1) with the coupler lock (2) inserted into the female coupler housing (4) or the male coupler housing (5) is assembled in the order of inserting, and the deformed rebar fixing washer (8) depth limiting The jaws 44 and 54 do not fall out.
- a fixed washer groove 81 is formed in the deformed rebar fixing washer 8 to prevent the node A1 from entering and shaking from side to side.
- the present invention can be carried out quickly and simply by using a high-strength reinforcing bar coupler without tying wires of reinforcing bars, by adopting a molded spring can reduce labor costs by reliability and high construction of the strength of the connection portion Since the air can be shortened, there is an effect that can finally reduce the construction cost.
