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.
