Rebar sleeve connection is  mechanical connection, which is divided into grades I, II , III. The grade I is that the tensile strength of the joint is not less than the actual tensile strength of the connected steel bar or 1.10 times the standard value of the tensile strength of the steel bar, and has high ductility and repeated tension and compression.

The grade II is that the tensile strength of the street is not less than the standard value of the tensile strength of the connected steel bar, and has high ductility and repeated tension and compression properties. The grade III is that the tensile strength of the street is not less than 1.35 times the standard value of the yield strength of the connected steel bars, and has certain ductility and repeated tension and compression properties.

The primary rebar sleeve is tensile strength of the first-level sleeve reaches or exceeds 596Mpa. In another word, the primary sleeve is a steel bar connection sleeve that reaches or exceeds 1.1 times the tensile strength of the steel bar base material.
