REBAR SPLICING SYSTEM
FROM BAR TO SITE
ONE PROCESS - ONE PRODUCTION WAY - ONE INSTALLATION
Certify :
A CONNECTION ALWAYS STRONGER THAN THE REBAR
Bar break with visible necking during tensile testsA CONNECTION TOLERANT TO MISTAKES
The full efforts are transfered even with defects of the rebargeometry and / or the installation
A FINANCIALLY EFFICIENT CONNECTION
through an industrial process, a manufacturing in large series
, a proximity of construction sites, simple solutions for complex cases.Production ratio
Time saving Standardization Time saving
Competitive prices even for complex connections
Easy installation on site Industrial manufacturing of the couplers
Conception
Thread coss section > rebar cross section, Thread length > standards for nuts and bolts,
Optimization of the external dimensions of the coupler Impossible to connect a continuation bar of a different diameter Impossible to screw the continuation bar on the bias Self centering of the continuation bar inside the coupler
Proper fitting is checked by a simple visual inspection
No Torque Wrench needed
Final control of dimensions isindépendent from
machinery : guaranty of conformity Cold upsetting + ISO profile thread with big pitch
Advantages and tolerated mistakes
Complete transfer of the effort even with a 20% unscrewed connection
Simple use even in projects with reinforcement congestion Security of the installation,
Blind installation of the continuation bar
in projects with reinforcement congestion
Anyone can at any time check the connections
with just one glance and with no tool No special tool, no calibrated tool
No risk to damage the cnnection with a too high torque
No risk that the torque is achieved but the efforts are not fully transfered
Mechanical tools for control : normalised and calibrated, no way to have measurement trouble Profile difference, height of the ribs (depending on the rebar trade marks) : no influence on the result Possible loss of material on the thread : no influence on the strength
PROCESS
COLD UPSETTING
followed by an ISO profile threading

PROduCTION
INSTALLATION
CUTTING :
The rebar end is cut with an automatic bandsaw.
THREADING :
The upset part is then threaded, by cutting for the range C, and by rolling for the range Dyn. All threads are in ISO-profile.
Those operations are done with a specific BARTEC Technology machinery.rond à béton des modes
COLD UPSETTING :
For each diameter, a machinery and specific dies are used to define and control the volume of material to move and ensure the result.
CONTRôLE :
A final check on the thread is proceeded with a predefined frequency :
With a calibrated ring for the profile and diameter, and with a depth gauge for the length.

Manufacturing of couplers
Rebar end treatment and Couplers
At this stage the product manufactured in
certified workshops is able to ensure the total transmission of effort
.
No other additional test or check is needed.
COUPLERS
The coupler is manufactured industrially under strict quality control.
The raw material has mechanical properties that are defined and permanently checked to ensure com-pliance of the connection to the most severe applications (earthquakes, shocks,...), the traceability of the material and manufacturing is ensured by a code stamped on each coupler.

INSTALLATION
The rebar is automatically centered bya chamfr at the end of the coupler. Impossible
to connect a continuation rebar of a
different Ø from that of the first rebar.
Tightened with a spanner with no need to
check the torque. Proper fitting by a simple visual inspection.
Four Types of connections using the same coupler.
