Parallel threaded joint is a cold-headed parallel threaded
reinforced joint with high-strength threads inside. (Rebar
connector) In this method, threads are cut on each side of the
rebar. The depth of these threads will be half the length of the
coupler. Then rotate around the rebar and complete the assembly. If
necessary, you will assemble the coupler on one side of the short
thread and use the required plastic protection accessories.
The use of parallel threaded connectors can simplify the planning
and construction of reinforced concrete and reduce the number of
steel bars required.
Each end of the steel bar to be connected is cut into a square and
enlarged using a cold forging process. A thread rolling machine is
then used to form threads on the enlarged rod end. The thread makes
the cross-sectional area of the top of the steel bar not reduce,
and ensures that the connection strength matches or exceeds the
strength of the parent steel bar.
Verify that the top load of each threaded rolled steel bar is
sufficient to meet the characteristic yield strength of the steel
bar. It is the combination of these processes that provides a
connection that enhances fatigue resistance.
