The Advantage of Concrete Reinforcing Bar Coupling Sleeve
Steel bar stripping and rolling straight thread connection is a new type of steel connection sleeve technology. Its structural principle is to strip off a part of the longitudinal and transverse ribs at the ends of the steel bars to be connected by cutting, and then directly roll them into ordinary straight After threading, it is connected with a special straight threaded steel connecting sleeve to form a steel connection.
The advantages of this connection method are as follows:
1. Good mechanical properties, safe and reliable connection: because the end of the steel bar is formed by rolling and the steel bar material is cold-worked, the strength of the thread and the steel bar are improved, which makes up for the weakening of the strength of the thread base diameter being smaller than the base circle diameter of the steel bar base material The influence brought about makes the joint strength of the connection higher than the strength of the base material, which can make the base material give full play to its strength and ductility.
2. Convenient connection: flexible operation in tightly arranged steel bars in a small site. Convenient construction and high efficiency: the steel connecting sleeve is prefabricated in the factory, and the quality is guaranteed: on-site rolling thread head equipment can process nearly 400 joints per shift, which has unparalleled advantages in the construction of large quantities of works and basement plates. , No pollution during construction, no open flame operation, safe and environmentally friendly, and can be constructed all-weather.
3. Convenient inspection: No special inspection equipment is required during construction, and the quality of the joint can be determined only by looking at the exposed wire teeth of the steel bar. Strong applicability: It is suitable for the steel connection of all seismic and non-seismic reinforced concrete structural engineering, and it is suitable for bending steel bars, fixed steel bars, steel cages, extra-long steel bars and other occasions that cannot be rotated.
