DESCRIPCIÓN
 
Smart Coupler innovatively improves the drawbacks of existing couplers. Perfect splicing can be completed by a single worker with a simple push and click. Along with its easy application comes top-notch structural performance. Simply put, Smart and Easy.
 
SECURING THE COMPLETION OF SPLICING
 
When a rebar is connected to the Smart Coupler with minimum hand pressure, not only you would hear a ‘Click’, but also feel the completion of coupling. This eliminates the possibilities of incomplete splicing without quality control.
 
MAXIMIZING THE EFFICIENCY OF SPLICING WORK
 
Typical Coupler – More than 2 trained workers needed
Smart Coupler – 1 worker needed – Only 2 seconds to spliceSmart Coupler saves you 80% of splicing time and 75% of manpower, which translates into substantial cost reduction.
 
ENHANCING THE APPLICABILITY
 
It can be easily spliced not only in general vertical beam, but also in difficult areas of splicing, such as floor (horizontal) beam, wall, and bridge sections.
 
STRUCTURAL EXCELLENCE
 
It is equipped with sufficient tensile strength for rebars over SD600, and also structurally optimized for Earthquake resistance.
 
WHY COUPLERS ARE NECESSARY
 
In construction, typical ways to splice rebar after rebar incur :
 
Rebar loss from overlapping
Structural defects
Lack of independent structural support in case of earthquake or natural disaster (Lap Joint method prohibited in Japan)
 
Due to above reasons, typical methods of rebar splicing are being replaced by Mechanical Splicing System, such trend prevalent in most developed countries
(Lap Splices)
 
PROBLEMS OF EXISTING COUPLERS
 
Problems of the existing couplers (Threaded Splices and Wedge Splices, etc.) include :
Incompleteness: It is difficult for workers to anticipate the timing of completion as they need to continuously apply force to tighten the threaded splice; this causes the need for control and increase in consequential costs.
Ineffectiveness: It requires additional craftspersons with specific tools to work for over 60 seconds.
 
LIMITATIONS
 
It is not readily applicable to difficult splicing construction surface, such as floor (horizontal), beam, and wall sections, requiring extra time and labor.
 
UNDERSTANDING THE TECHNOLOGY
 
As for the existing types of mechanical coupler, rebar is locked by the joint with the groove of the coupler. But since rebar joint’s width, height and pitch varies by manufacturer, it is difficult to expect consistent tensile strength from the existing types. When rebar is inserted to the ‘Smart Coupler’, the center of plastic holder (30) breaks through and the inner shell (20) strongly grasps not only the joint, but also the body and rib of rebar with its sharp teeth(21). This mechanism allows to perfectly grip all kinds of rebar and results in steady tensile strength regardless of rebar type, manufacturer or country of origin.
