The connection technology of steel rebars is a new type of rebar connection technology. Its structural principle is to strip a part of the longitudinal ribs and transverse ribs of the steel bars to be connected by cutting, and then directly roll them into ordinary straight threads. It is connected with a special straight thread sleeve to form the connection of the reinforcement. The advantage of this connection is that it has no false threads, good mechanical properties, safe and reliable connection, and is equivalent to reinforcing bars and base metal. The joint performance of this technology has reached the indexes of Class I joints in JGJ107-2003.
The reinforced steel connecting sleeve produced by our company has the advantages of high joint strength, fast connection speed, strong applicability, high construction efficiency, material saving, energy saving and economy. Rebar connection sleeves are suitable for all kinds of reinforcement connection projects. The rebar connection sleeve produced by the company is inspected by the National Construction Engineering Quality Supervision and Inspection Center. All the items are in compliance with the standard. The performance is not less than 45 carbon structural steel. Its mechanical properties and chemical composition conform to GB699 standards. The standard value of the bearing capacity and tensile strength is reported to be 1.10 times that of the corresponding bearing capacity of the steel bar. Rebar connection sleeve made of connection
The tensile strength of the head is greater than the tensile strength of the reinforcing bar base metal and greater than 0.9 times the measured tensile strength of the reinforcing bar base metal.
