Changsha DLADTO Rebar Splice Co., Ltd

In the building construction, steel bar is an indispensable material, and steel bar joints are an important part to connect steel bars in construction. According to different connection strength requirements and connection methods,   couplers   can be divided into first-level joints, second-level joints, and third-level joints. What is the difference between them? 1. Different mechanical properties Grade I joint: the tensile strength of the joint is greater than or equal to the actual tensile strength of the steel bar to be connected or 1.10 times the standard value of the tensile strength of the steel bar, and it has high ductility and repeated tension and compression properties; Class II joint: the tensile strength of the joint 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; Grade III joint: The tensile strength of the joint is not less than 1.25 times the standard...

The difference between the grade I, II, III   rebar joint ： Different mechanical properties Grade I rebar joint: the tensile strength of rebar joint is greater than or equal to the actual tensile strength of the connected steel bar or 1.10 times the standard value of the steel bar tensile strength, and it has high ductility and repeated tensile and compressive properties; Grade II rebar joint: the tensile strength of rebar joint is not less than the standard value of the tensile strength of the connected steel bar, and it has high ductility and repeated tensile and compressive properties; Grade III rebar joint: the tensile strength of rebar joint is not less than 1.25 times the standard value of the yield strength of the connected steel bar, and it has certain ductility and repeated tensile and compressive properties. Different percentages of rebar joint The percentage of Class I rebar joint has no specified limits unless there are special requirements; The percentage of Class II r...
