Various Types of Threaded Rebar Couplers

Straight Threaded rebar couplers are very common equipment is construction, which is usually used  to connect reinforcement to make the reinforcement structure much stronger. Of course, the products contains many kinds of types, with each type for different uses and different steel bars. 

Straight Threaded Coupler with Upset Rebar Ends

This is a mechanical splice consisting of forming heads on the ends of the bars to be connected using a hydraulic machine from the splice manufacturer, which is designed to fit between closely-spaced bars. The upset bar ends are butted to each other and are held in place using a male and female straight-threaded coupler that is positioned onto the bars prior to forming the heads. The coupler is installed by turning either the male or female component and tightening to the manufacturer's recommended torque; no rotation of the bar is required. Bent or curved bars can be spliced with the same device. Adaptations permit use for end anchorages in concrete or connection to threaded rod.

Extruded Coupling Sleeve

This type of mechanical splice is produced by cold extruding a coupling sleeve over both bar ends in one operation. The coupling sleeve is then centered over the butted bar ends and is connected to one bar by tightening a set screw. A hydraulic press, designed to fit between closely-spaced bars of reinforcing steel, then pushes a drawing die over the entire length of the coupling sleeve. The coupling materials flow tightly around the bar deformations, which creates a splice. Extruded transition coupling sleeves for splicing two different size reinforcing bars are also available. Bars may be shear-cut, flame-cut or saw-cut; however, a bar-end check is recommended.

Taper-Threaded Coupler

This is a mechanical splice consisting of a taper threaded coupler that joins bars with matching tapered threads. The coupler is installed by turning the the bar or sleeve with wrenches to the manufacturer's specified torque. For splicing bent or curved bars, special position couplers with collars are used. Adaptations permit the use for end anchorages in concrete or connection to structural steel members. Bar ends may be shear-cut or saw-cut. Bar ends require taper threading over a specified length. And to process the steel bars that can connected with threaded rebar couplers, you need to buy a steel bar threading equipment.  

Coupling Sleeve with Double Wedge

This coupling sleeve consists of a ductile iron sleeve with two internal wedges. Two series of cone-pointed screws are arranged a long the sleeve length, opposite a wedge-shaped profile in the sleeve. Each reinforcing bar extends out of the sleeve by approximately one bar diameter. No special bar end preparation is required. As the screws are tightened, they indent into the surface of the bars, and wedge the bars into converging sides of the sleeve profile. Screws can be tightened using suitable impact wrenches or hand-held ratchet wrenches. The heads of the screws are designed to shear off at a prescribed tightening torque.
