Usage Instruction of Rebar Coupler
.jpg)
1. High connection strength, stable and reliable connection quality. The joint strength meets the industry standard JGJ107-2003. The tensile strength should not be less than 1.10 times of the actual tensile strength of the connected steel bar or the standard value of the tensile strength of the steel bar. 2. Good fatigue resistance. The joints pass the two million fatigue strength tests specified by the industry standard. 3. Material saving. Take the steel connecting coupler with a diameter of 40mm as an example, the mass of the extruded sleeve is 4kg, and the straight thread sleeve is 1.1kg. The quality of the straight thread rebar coupler is 25% of the extruded rebar coupler, and the joint performance is the same as extruded joint. 4. Convenient to connection. The processing of steel wire head is factory-like and don't need lot construction time. On-site connection and assembly operations take a short time. 5. The steel wire head is easy to process. The two proces...
