On site rebar coupler threading machine

Mechanical splices on site coupler system

The Terwa mobile units are created for the need to optimize and streamline the work of the builders
at the construction sites and to have the products available on site in the fastest way possible.
At this time, Terwa owns various fully equipped mobile units that can be used to press couplers on a
length of 1-12 meters of rebar steel or, occasionally, even longer lengths.

Properties and benefits of the mobile unit for rebar coupling include:

• Local installation for the direct connection of rebars with diameters between 12 and 40 mm.
  
• Completely self-supporting, including necessary energy supply.
  
• Connection of rebars of any length.
  
• Tested and certified to national and international standards.
  
• Possibility to use locally supplied reinforcing steel.
  

Product variants:
Terwa rebar connection system: PSA/PSC/PSA couplers for reinforcing bars with dimensions between 10 and 40 mm.

Mechanical splices on site threading system

Threaded bars on site
The mobile units for threaded bars on site provide a simple and fast way of connection the rebars on
site. The splicing system is designed for the connection of reinforcement steel bars from Ø12 to 40
mm.

The system is produced using 3 machines with high productivity:

• Cutting machine.
• Upset cold forging machine.
• Threading machine.

Connection consists in a threaded bar which is connected using a threaded coupler. Before
threading, the bar is first cut so it has a straight surface, after the diameter of the rebar is enlarged to
increase the nominal area and the strength.
