Precision Taper Thread Rebar Coupler For Inclined Reinforcement Connection Works

Unlike conventional parallel thread couplers with equal-diameter inner holes, this product adopts gradual conical thread design from end to middle. The tapered profile creates automatic wedging force during screwing. When bearing axial tension, the fitting degree between thread and rebar will become tighter, which effectively stops loosening caused by building vibration and alternating load. The whole body is one-piece forged and machined, owning solid structure and strong anti-deformation capability.

Rebar connection range: from 12mm to 40mm.

Meet the requirements of steel bars: HRB500/B500B/SD600/ASTM 75

Material: 45C/40CR

▎Advantages:

• Allows maximum bar cross-section to be used

• Smallest diameter in the industry reduces need for concrete cover and eliminates rebar congestion

• Short length and slim design ensure the least disturbance to uniform stiffness

• Splice strength is independent of rebar deformation

• Unique tapered thread requires no lock nuts and provides a positive locking, no-slip connection .

• Any length, shape, diameter or combination of bar sizes can be mechanically spliced

▎Application & Installation Position

• Main bar diameter change in columns (most commonly used and recommended): Frame columns, shear wall columns, stair columns, and construction columns. When the diameter of the steel bars decreases as the floor level increases: diameter-changing coupler are the best solution.

• Vertical bar diameter change in shear walls: From large diameter at the bottom to small diameter at the top of shear walls, diameter-changing coupler are faster and more reliable in quality.

• Main bar diameter change in beams: Frame beams, secondary beams, and foundation beams: when the diameters of the longitudinal bars and support bars are different, diameter-changing couplers are more reliable and faster than welding or lapping.

• Diameter-changing parts in foundations and basements: Main bars of pile foundations connecting to columns, and main bars of pile caps and foundation beams: in critical load-bearing parts underground, diameter-changing coupler should be given priority.

▎FAQ

1. Is taper thread coupler reusable after disassembly?

   It is designed for one-time engineering use to ensure long-term structural safety, repeated disassembly is not recommended.

2. Can it match standard threaded rebars?

   Yes, it is processed according to industry standard taper parameters and compatible with matched threaded rebar ends.

3. Can anti-rust coating be added for outdoor projects?

   Hot dip galvanizing and epoxy anti-corrosion treatment are available on request.
