steel coupler

 

1. 100% Bar Break Performance 
CABR Bar Splice is a parallel thread mechanical splicing system designed for the connection of concrete reinforcing bars from Φ16~Φ50. 

2. Product Features 
* Designed and manufactured in compliance with ACI318, JGJ107, UBC 1997, BS8110, NF35-20-1, DIN1045, ISO/WD 15835 (Draft). 
* Full-Tension splice, bar break under tensile tests. 
* Easy to operate and maintain, High production efficiency and fast installation, no need for skilled technicians. 
* Several types of splices, which could be suitable for rebar splicing when the rebar cage or the bending rebar is used. 
* The splices could be produced in advance without influencing the construction period. 
* Inexpensive to purchase, maintain and repair. 
* Couplers and threaded bars are protected by plastic cover. 
* Full traceability of material origin and production batch. 
* Manufactured under strict quality assurance plan ISO 9001. 

3. Benefits: 
* No staggering of spliced bars required. 
* Practical alternative to lap splicing. 
* Solves bar congestion problems. 
* Shortens construction cycle time. 
* Reduces steel wastage. 

4. Product type: 
4.1 SYS A: Parallel Thread Rebar Splicing with Cold Upsetting End 
Principle: 
(1) Enlarging ends of reinforced bars by cold upsetting; 
(2) Threading parallel threads; 
(3) Splicing rebars by coupler. 

4.2 SYS B: Parallel Thread Rebar splicing with Rolled Thread End 
The technologies of parallel thread rebar splice include directly rolling and Rolling after stripping rib. 

Directly rolling: 
(1) Cutting off the end of the rebar; 
(2) Rolling the end by using the special rolling machine; 
(3) Splicing the rebar by using the coupler. 

Rolling after stripping rib: 
(1) Cutting off the end of the rebar; 
(2) Stripping the ribs at the end of the rebar and rolling thread; 
(3) Splicing the rebar by using the coupler.
