Couplings Bartec, Dextra, Ankon

The Bartec mechanical (coupling) connection is a joint of two reinforcing bars with a thread pre-cut at the ends, connected by means of a coupling with an internal thread similar to the thread profile on the bars.

The Bartec technology system provides reliable, equally strong joints and continuous structural integrity of reinforcement in reinforced concrete structures. Composite reinforcing bars connected by couplings behave as continuous sections of reinforcing steel, providing design tensile, compressive, and in cases of alternating stresses.

Elements of the Bartec technology system:
- couplings of various types (standard, transitional, positional, welding, anchor),
- equipment for forming threads on reinforcing bars,
- technology for forming threads on reinforcing bars,
- technology of coupling joining of rods in the reinforcing cage

Bartec couplings are a factory-made mechanical device made of steel in the form of a cylindrical tube (sleeve) of a given size (parameter) with a threaded internal parallel (cylindrical) thread.

The set of equipment for forming threads on reinforcing bars includes three types of equipment: a band saw, a cold pressing machine and a thread-cutting machine, as well as special equipment and tools. The equipment is installed in a standard 20-foot container (dimensions: 2.50m x 6.08m x 2.58m).

The technology for forming threads on reinforcing bars consists of three sequential operations:

1) Trimming (trimming) the end of the reinforcing bar

2) Cold pressing: increase the initial outer diameter of the end of the reinforcing bar to the required size using the patented method of cold pressing.

  3) Threading at the sealed end of the reinforcing bar

The technology of coupling joining of reinforcing bars does not provide for a special mounting and control tool.
