Description:
?
Plain couplers is used to connect reinforcing bars of the same size.? Couplers are easy to install and achieve failure loads higher than 115% of the characteristic yield strength of grade 500 reinforcing bar. Neither bar end preparation to form threads, nor bar rotation are required. couplers can also be used to join imperial, plain round or deformed reinforcing Bars. The bar ends are supported within the coupler by two serrated saddles, and as the lockshear bolts are tightened, the conical ends embed themselves into the bar. As this happens the serrated saddles bite into both the bar and the shell of the coupler. The lockshear bolts of couplers up to and including the 20mm can be tightened using a ratchet wrench. For larger couplers a nut runner is recommended.
?
In all cases heavy duty sockets should be used. When the pre-determined tightening torque for the bolts is reached, the heads shear off leaving the top of the installed bolt slightly proud of the coupler. This provides an instant visual check of correct installation.

Competitive Advantage:
?
1. Meets or exceeds major international building code and the request of ISO9001, ACI 318, and BS8110.
2. Is smaller than other bolted splices currently available.
3. Performs like a continuous piece of rebar.
4. Works in repair, bent bar, retrofit, precast closure pour and new construction applications.
5. Meets slip criteria of less than 0.10 mm (0.0039 in).
6. Provides superior fatigue performance.
7. Works with a variety of standard US and international rebar grades.
8. Installs quickly and easily using simple hand tools — does not require special skilled labor.
9. Allows for simple visual inspection.
10. Works as one-step transition on ASTM (in-lb) and metric rebar.LCD AD player
