Building use upsetting rebar coupler parallel threads with high
Multi-section bar when the steel joints, before the use of welding
or lashing overlap, not only a waste of materials, and welding
speed, welding quality is unstable, it is difficult to ensure the
progress and quality of the project. Guangming Expressway extension
line engineering design requirements, diameter ≥ 25mm reinforced
with mechanical connections, combined with the project's
engineering characteristics and standardization of construction
requirements, reinforced with concentrated processing. To meet the
design requirements, saving materials, to ensure the quality of
steel connections, the progress of the project to meet the
requirements of steel connections using upsetting straight thread
Advantage of upsetting rebar splicing coupler:
High strength: upsetting section of steel rolling thread after the
cross section is greater than the steel base section, so as to
ensure that the joint strength is greater than the strength of
Higher bar connection speed: the use of straight thread sleeve
connection, the connection will be tightened with a torque wrench
on the steel can, greatly reduce the labor intensity, saving time.
The connection speed of multi-section steel cage is greatly
accelerated, and the construction efficiency is obviously improved.
Strong adaptability: the implementation of the connection without
electricity, without gas, anonymous fire operations, no air
pollution. After the centralized processing to the scene, in a
small site or reinforced arrangement can also be intensive. Rain,
snow, low temperature and other weather conditions can also be
Stable connection performance: the sleeve for the manufacturers,
steel wire head processing from the processing center, the
construction site only need to connect the sleeve and steel, to
avoid the construction conditions on the joint performance.
Technical parameters of upsetting couplers we have made
(1) We also have Reducing rebar coupler, Left handed and right handed rebar coupler.
(2) We could provide according to your drawings;
(4) The delivery time depends on order quantity
(5) Marking is available
Suitable for bridge and culvert engineering, tunnel engineering and
industrial and civil construction of reinforced concrete works.
Upsetting Straight Thread Sleeve The connection is to use the
upsetting machine to upset the end of the steel bar, and then use
the straight thread rolling mill to wire up the upsetting section,
through the straight end of the steel screw thread and straight
thread sleeve bite the formation of a connection.

Reinforcement ends are flattened
1, steel bending straightening, and then use the grinding machine
cutting cutting, to ensure that the vertical steel bar reinforced
steel plate. The following are the same as the "
2, the entire use of steel, the application of the deformation of
the end of the deformation of the end part (usually 1 ~ 2cm).
