Bar couplings are the latest method for reinforcement connection in construction. Couplings are used in Russia, Europe, the USA and Asian countries.
Bar couplings are used in the construction of both public and residential buildings and structures, as well as in the construction of structures with increased load-bearing loads: hydroelectric and nuclear power plants, stadiums, railway and metro stations, bridges and overpasses. They allow to connect any types of reinforcement, including heat-strengthened ones.
The assembly time of a threaded coupling reinforcement connection is up to 10 times faster than tub welding.
Coupling connection of bars is up to 2 times cheaper than tub welding.
Coupling application is recommended for construction in earthquake endangered areas.
TYPES OF STEEL REBAR CONNECTION
There are 3 main types of connection:
Lap joint doesn’t require additional devices making the process easier and less expensive and, thus, widely used in real works. However, when applying lap joint, building bars loses are about 25%.
The tub welding method provides a fairly reliable connection, but takes longer than other methods and requires highly qualified assemblers.
Coupling connection technology is modern and technological reinforcement joint method in construction, having the following advantages:
Our couplings are designed and produced in Russia complying all regulations!!!
