1.100% Bar Break Performance CABR Bar Splice is a parallel thread mechanical splicing system designed for the connection of concrete reinforcing bars from Φ 12~Φ 50.
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 Tread 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.
