It is a coupler designed for projects where steel and reinforced concrete are used together. One side of the coupler is a butt left open for welding and the other side is upset threaded system coupler. With this method, transition from steel to reinforced concrete is provided by a coupler. When this coupler is used, the coupler is first welded to the steel area. Cold headed threaded reinforcement is rotated to coupler and the assembly is completed.PRODUCT VIDEO

Welding of Couplers
Regbar Weldable Couplers offer the perfect solution for connecting the iron rod to a steel superstructure or individual assemblies. The fasteners have the same mechanical properties withRegbar’s Weldcoup Standard Couplers and an inclined tip for welding.
Welded joints can be arc welded at the manufacturing workshop or in the work site. Some welding factors and welding design depend on the material to which the couplers are welded. Regbar recommends a qualified engineer to review all common design and data requirements, including the procedure for selection of welding filler, local rules and advises.
For reasons of applicability, there are normally two general arc welding processes used in construction sites and manufacturing workshops:
1-Manual metal arc welding (MMA) / (SMAW): Suitable for accessibility problems and / or welding conditions at construction site.
2-Active Metal active gas welding (MAG) / (GMAW): Mainly used in manufacturing workshops.
According to the dominant application codes Regbar Weldable Couplers don’t require pre-heating before welding. However, there are several factors that may require pre-heating. Therefore, carbon equivalent and thickness measurements of the material to which the coupler is welded are important. Regbar recommends you to follow the American Resource Association (AWS) Structural Source Code D1.1.
Before welding Regbar Couplers the local area must be cleaned or wire brushed and the plastic cover should be removed from the couplers. In the correct assembly, both surfaces should be aligned without any visible voids between the coupler and the material it is welded. The couplers should be welded in three symmetrical positions and then balanced to ensure proper alignment.
Reinforcing Bar Couplers- Sleeved Reinforcing Bars
Overlapped inserts are not always appropriate tools for coupling rebars. Regbar Reinforcing Rebar Couplers Using Rebar Couplers simplifies the design and construction of reinforced concrete and reduces the amount of required bars. Regbar Mechanical Reinforcement Couplers provide solutions for construction reinforcement bundles such as overlap and welding.
Our strategy is offering more affordable and extremely safe rebar inserts as compared to the options of overlapping and welding. RegbarMechanical Reinforcement Couplersand equipment are economic, safe, designer-friendly and easily applicable. In brief, Regbar provides matchless benefits and higher earnings to its customers!
In the Overlapping Method, concrete is required for load transfer. In addition, when the reinforcement reaches the zone of leakage and its diameter changes, clamping ends and the joint doesn’t work. At joints made by Regbar Reinforcing Rebar Couplerssuch clamping is not needed and thus, the joint continues to take on load in keeping with the tensile strength. It delivers outstanding performance at cold joints formed between the floor columns.

Regbar Upset Parallel Thread Rebar Couplerscover the processes of cutting bars, upset forging and high profile tangential threading of rebar ends by using Regbar equipment designed for this purpose.
This method provides larger diameter reinforcement ends for thread cutting and loss of cross-section equilibrium. Ends of the rebars previously cut by rebar manufacturers/subcontractors in the field have an undulated surface.
Regbar recommends utilization of professional, highly efficient, cost-effective Reinforcing Rebar Couplers which prevent intensive rebar loss and reduce labor time by professional rebar applicators.
ARegbar Upset Parallel Thread Equipment Setconsists of a rebar cutter or a hacksaw, a high-pressure cold press and a section (cutting ?) thread cutting machine designed for ribbed rebars.

As seen in the attached photos of the mobile equipment which can be quickly installed in the field, our products facilitate thread cutting on the rebar and reduce the logistics cost as the reinforcements will not be transported for thread cutting. All of the machines and equipment provided are designed and manufactured by Regbar. Quality of our equipment has received CE and ISO 9001 certificates. The equipment is shipped to the field in the container area ready for operation. It contains Cold Forging Press, Rebar Thread Cutting Machine, Band Saw and Grinding Machine.
