Changsha DLADTO Rebar Splice Co., Ltd

Rolled straight threaded rebar splice   is the joint formed by rolling the end of the steel bar or the extrusion (rolling) of the rib rolling or the stripping of the rib and the rolling of the straight thread and the thread of the connecting piece. The basic principle is to use the characteristics of metal materials that are plastically deformed and then cold hardened to enhance the strength of metal materials, and the plastic deformation and cold hardening occur on the surface of the metal, while the performance of the original metal is still maintained inside the metal, so that the steel bar joint and the base metal reach equal strength. There are three types of rolled straight threaded rebar splice: direct rolled threaded, extruded (rolled) rib rolled threaded, and stripped rib rolled threaded. The threaded accuracy and size obtained by these three types of connection joints are different, and the quality of the joints also different.

Quality requirements for   reinforcement joint sleeve : ① There are no cracks on the surface of the connecting sleeve, the threads are full and there are no other defects. ② If the profile specification is qualified, check the dimensional accuracy with a straight thread plug gauge. ③ There type and specification such as steel grades, diameter of connecting sleeve must be marked on the surface of it.  ④ The holes at both ends of the connecting sleeve must be sealed with plastic caps to keep the interior clean to protect it from rust-proof. Changsha DLADTO Rebar Splice Co., Ltd  is a professional rebar coupler producer, we have been in this field for a long time with customers for all over the world. If you have any inquiry, welcome to contact us.

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...
