Product description
Rebar splicing couplers can simplify the
design and construction of reinforced
concrete by reducing the amount of steel
used in overlaps and avoiding congestion
within the concrete.
Bartek Systems Couplers are produced
from Carbon Steel alloys with high tensile
strength characteristics. The couplers are
being produced with automatic CNC
machines to ensure higher precision to the
thread and make our coupler superior or
equal to the highest standards.
Bartek Systems couplers are suitable for
mechanical splices with reinforcing bars
made according to DIN 488:86,
BS4449:1997, ASTM A615.
Bartek Systems couplers comply with the
following bldg. codes and standards:
The Deutsches Instit für Normung, in
its standard DIN 1045 (2001)
The British standards Institution, in
its standard BAS 8110-1:1997,
section 3, chapter 3.12.8.
The Association “Française de
Normalisation” (AFNOR), in its
standard NF A 35-020 (1999)
The American Concrete Institute
(A.C.I.), in its standard ACI 318
(Chapter 12: Development and
splices of reinforcement)
The International conference of
Building Officials (ICBO), in its
Uniform Building Code (UBC),
Section 1912

Reinforcement rebar
Couplers
BARTEK SYSTEMS Coupler Splicing System Bartek Systems coupler splice is designed to connect two steel rebars without torque wrench;
the installation is fast and simple which increases the productivity and reduce the factor of
worker’s related mistakes.
Bartek Systems coupler spliced connection offers a higher
safety since the breaking load capacity of the splice is higher
than the steel rebar itself: Bar Break System.
The high strength of the coupler connection is being
achieved by cold forging. The pressed rebar end has a larger
core diameter than the bar to ensure that the joint is
stronger than the rebar.
Parallel metric threads are cut on the enlarged ends, the cold
pressing eliminate the risk of steel characteristic changes which
may occur if any other splicing method involving heating has
been used. Bar break couplers are recommended for the
applications with highest safety requirements.
The couplers are available in the standard diameters of 12 mm to 40 mm. Other diameters
could be produced upon request, and special coupler types can also be produced depending
on any project’s requirement.
STEEL REBAR IN CONCRETE WITH COUPLERS
STEEL REBAR CONGESTION IN CONCRETE WITHOUT COUPLERS
Lapped joints are
dependent upon the
concrete for load
transfer. For this reason,
any degradation in the
integrity of the concrete
could significantly affect
the performance of the
joint. The strength of a
mechanical splice is
dependent on the
concrete in which is
located.
We design and produce special
solutions according to the
requirements of our clients.

Fix and rotate the coupler to the rear of the thread on the fixed bar and lock tight. The bar end should be
central within the coupler.
Remove the plastic cap from the coupler. Position and rotate the continuation bar in the coupler.
Tighten the joint using wrench on the continuation bar. After tightening there should be more than 2 - 4 mm of the thread
exposed, depending on the diameter of the rebar.

BARTEK SYSTEMS Threading – Types
Bartek Systems Type – A
This is used where the continuation bar can be rotated. The end
of the bars are upset and threaded for half length of the
coupler.
Bartek Systems Type – B
This is used where it is not possible to rotate the
continuation bar. Therefore the thread of the
continuation bar is extended to full coupler length.

This type has an additional locknut and is used where
the continuation bar cannot be rotated. The
continuation bar is threaded for full coupler length
plus the length of the locknut.
Fix the coupler to the rear of the thread on the continuation bar.
Position the continuation bar with the coupler against the end of the first bar.
Rotate the coupler from the continuation bar to engage against the rear of the tread
on the opposing bar and lock tight.
Using wrench, rotate the continuation bar to lock the two bar ends against each other. After tightening, the length of exposed
thread should not be more than half of the coupler length plus 2 - 4 mm depending on
the diameter of the rebar.
Turn the locknut followed by the coupler to the rear of the thread on the continuation bar.
Position the continuation bar with the coupler against the end of the first bar.
Rotate the coupler from the continuation bar to engage against the rear of the thread on the
opposing bar and lock.

BARTEK SYSTEMS “H” Hydraulic Pressed Couplers
Advantages:
High tensile strength to meet the German standard (DIN 1045), British standard (BS
8110)
The hydraulic pressing method of our couplers complies with ACI439 3.3.1 cold swaged
steel coupling sleeve.
According to the requirement of ACI439 type I, par. 1.1.2, the tensile strength of the
splice should reach 1.25 times of the yield strength of the same rebars used for the
splice, while the type II should achieve the same tensile strength of the rebars. Take
splicing DIN 488, ASTM A615/A615M Grade 60(420) for type I, tensile strength of splice
needs to reach 1.25*420=525 MPa; if type II, tensile strength of splice needs to be
higher than 620 MPa (Grade 60 bar’s min tensile strength). For our standard hydraulic
pressing couplers, they meet type I and type II when splicing DIN 488, ASTM
A615/A615M Grade 40/Grade 60, ASTM A706/A706M and other similar rebars, for
higher strength steel bar, we can supply higher strength couplers.
Rotate the locknut along the continuation bar.
Hold the rebar in its required orientation and with a wrench tighten the locknut against the
coupler.

Chemical couplers
Chemical Coupler is a half-threaded mechanical splicing system specially designed for the
connection of precast concrete elements and filling connection sleeve design. Structural
reinforcement for concrete structures, structural design, there should be the implementation of
the provisions of the current national standard "design of concrete structures" GB 50010,
"Seismic Design Code" GB 50011, "Technical Specification for prefabricated concrete
structures".
Bolt couplers
The Bolt Couplers are used for splicing any grade or
profile of reinforcing bar. These couplers are made for
reinforcement steel with diameters in the range of 10
mm to 40 mm. Connection is made by inserting bars
into both ends of the coupler. The breaking bolts are
then screwed by hand and tightened by ratchet
wrench until bolts shear off. These couplers can be
used in particular cases to replace the damaged
reinforcements with new ones and to connect to old
structure.
We design and produce special
solutions according to the
requirements of our clients.
