Rebar Coupler

Parallel Thread Rebar Splice with Upset End
PrincipleCABR Coupler for rebars

1. 100% Bar Break Performance
CABR Bar Splice is a parallel thread mechanical splicing system designed for the connection of concrete reinforcing bars from ¥´µ12~¥´µ50.

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.

Features:
* High splice strength, which could exert the ultimate and compression strength of rebar, it could satisfy the requirements stipulated in the Chinese standard JGJ107, American standard UBC 1997,and other requirements in the relevant standards home and abroad;
* Simple operation, fast splicing;
* Several types of splices, which could be suitable for rebar splicing when the rebar cage or the winding rebar is used;
* High production efficiency, it only takes less than 1 minute to upset and thread one thread on the site;
* High adaptability, the splicing could be conducted when the power is off, or under water, or at super high position, or windy, rainy and snowy weathers.
* Environment-friendly, material-effective and economic;
* Inexpensive to purchase, maintain and repair.
