One-Touch Power Coupler
Social distancing: Possible to be installed by only one worker. Environmental friendliness: Reduced carbon footprint on the job site and reduced fuel emissions caused by cranes Productivity and efficiency improved: Increased economic effects by shortening the construction period and securing safety by improving the working environment
Benefits
- 01Easy (one-touch)
- 02Cheaper (only one worker required)
- 03Faster (5 seconds)
- 04Great cost savings (working hours/period & labor costs)
- 05Simple (no tools required)
- 06Patented technology
As a patented product that complements the durability of existing rebar couplers, there is no risk of damage to the extension of the support members due to the friction or load of the rebar when used at an actual work site. It is a product that can satisfy both the safety of the site and of workers. In addition, the jaw, which is a unique structure formed on the connecting piece that wraps and supports the rebar is excellent for preventing the protrusion and separation of reinforcing bars and while also providing more excellent rebar bonding power than existing products.
Features
* HK Sun Tech’s power coupler with four jaws has been designed to fix steel bars even more tightly.
1) Uses a tapered spring to prevent jaws from being separated by a concentrated force. 2) Manufactured to fit the size of the steel bar by minimizing the inner dimension of the jaw toward the center. 3) The jaws (horizontal/vertical spiral cutting), sharply diamond-cut with a machine (horizontal/vertical spiral cutting), can hold the steel bar tightly like a spiral nail and dig deeper when they are pulled out. Therefore, it is suitable for high-cycle fatigue testing and good for railways, bridges and other infrastructure.

Raw materials
- * Chemical composition
- Carbon(C) : 0.42 - 0.48%
- Sulfur(S) : ≤ 0.035
- Silicon(Si) : 0.15 – 0.35%
- Copper(Cu) : ≤ 0.30
- Manganese(Mn) : 0.60 – 0.90%
- Nickel(Ni) : ≤ 0.20

- Chromium(Cr) : ≤ 0.20
Method of Construction
1. Insert the one-touch coupler while maintaining straightness at the entry.
(Burrs attached to the cut surface upon rebar production will be connected with a chamfer remover or grinding.)
2. If there is a click sound, it has been connected properly.
3. Visually inspect or shake by hand to check whether the rebar has been inserted in a straight line.
Precautions
- After construction, completely remove any foreign substances inside before pouring concrete. - When storing the coupler, keep it after sealing to prevent foreign substances such as oil from coming into contact with it. - When using a coupler, the cover thickness decreases, so it is necessary to check the cover thickness and joint position.
