Rebar coupler, also named as rebar connection joint, is a fastening use to connect two rebars.

Straight Threaded Rebar Sleeve is one kind of rebar couplers. It has the advantages of high connection strength, stable & reliable connection quality, convenient construction, fast connection speed, environmental protection construction. etc.

The technical characteristics of straight rebar thread sleeve

1. High connection strength, stable and reliable connection quality. Good fatigue resistance performance. The rebar connection joint has passed two million fatigue strength tests stipulated by industry standards.

2. Convenient construction and fast connection speed. Factory-based processing of steel wire ends does not take up the construction period. On-site connection and assembly operations take a short time. The steel wire head is easy to process. The two processes of rib stripping and thread rolling can be completed once the steel bar is installed. Fast processing speed and high forming thread precision.

3. Environmental protection construction. The steel wire head processing and joint construction site without noise pollution, no fire, no smoke, safe and reliable. Save energy, save materials. The equipment power is only 3~ 4KW, does not need special distribution facilities, does not need to set up special wires. Good resistance to low temperature. Pass the low-temperature test. All-weather condition construction. Not affected by wind, rain, snow, and other climatic conditions.

4. Good mechanics performance, safe and reliable connection: Because the end of the steel bar is formed by rolling and the steel bar material is cold-worked, the thread and steel strength are improved, which compensates for the influence of the thread base diameter is smaller than the base circle diameter of the steel bar on the weakening of the strength and makes the joint strength of the connection. Higher than the strength of the base metal, the base metal can give full play to its strength and ductility.

5. Convenient connection: It can be operated flexibly in the densely arranged steel bars in a small site. Convenient construction and high efficiency: the steel connecting sleeve is prefabricated in the factory, and the quality assurance: on-site rolling thread head equipment can process nearly 400 joints per shift, which has unparalleled advantages in the construction of large works and basement plates. No pollution during construction, no open flame operation, safe and environmentally friendly, and can be constructed in all-weather condition.

6. Easy to detect: the construction does not need to use a piece of specific detection equipment, just look at the steel bar exposed wire teeth can determine the quality of the joint.

7. Strong applicability, a wide range of applications. The steel bar has no weldability requirements, applicable to all seismic and non-seismic reinforced concrete structural engineering steel bar connections, and bending steel bar, fixed steel bar, steel cage, long steel bar, and other occasions can not rotate are applicable.
