Position Upsetting Coupler

Position Upsetting Coupler

Specifications

Aleono Upsetting Parallel Threaded Rebar Coupler is designed to produce a full strength mechanical joint between reinforcing bars with upsetting ends. It is used for rebar mechanical splicing in the concrete structure. It can connect re-bars of same or different diameters laterally, vertically and slantingly. It is broadly applied to the Tunnel, Tower, Bridge, Subway, Airport, Nuclear Power Station, High Rise Building and more. Aleono Parallel Thread Rebar Coupler including Standard Upsetting Coupler, Position Upsetting Coupler,  Transition Upsetting Coupler and more.

Position Upsetting Coupler is also known as Left-handed & Right-handed Rebar Coupler, It is designed to splice two upsetting reinforcing bars when both of them can not be rotated but at least one of them can be moved axially. The position upsetting coupler has the female thread with half left-handed thread and half right-handed thread, the left-handed thread, and right-handed thread cross together in the middle of the coupler.

It is mostly adopted under the steel bar with Bended-hook.

Technical Parameters

Product Advantage

1. Raw material-saving, high energy saving, high work efficiency.

2. Construction Environmental Protection. no flame, no noise pollution.

3. It is not be affected by the chemical compositions and types of reinforced bars and won’t be influenced by weather and work-site.

4. Low cost, simple operation.

5. Can be prefabricated and the construction period can be shortened.

6. High dimension precision, reliable quality and Stable performance.

7. High strength. The tensile strength usually more than 600 Mpa, it can reach 110% of yield strength of parent rebar.

8.  After 2 million times of fatigue strength test, the connection is in good condition.

9. According to the inspection of National Construction Quality Supervision and Testing Center, the rebar coupler joint performance has reached the Grade I splicing rebar joint of JGJ107-2016 Industry Standard.

Packaging

PP Woven Bags are used inside, Wooden Case is used outside. Products also can be packed according to customer’s special demands.

Protection

To prevent dust and debris into the rebar coupler, we suggest you protect the coupler with Protective Cap before you use it.

Operation

First of all, you should process thread on the upset rebar end, ensure rebar threaded sectors with the same diameter and one of the rebar threaded sectors with left-handed thread, the other one with right-handed thread.

(1) Cut the rebar end with the Rebar Sawing Machine, ensure the cut surface is flat.

(2) Enlarge the rebar end with the Rebar Upsetting Machine,  ensure the upset end can meet the requirements of rebar thread processing, and the length of upsetting rebar end should be more than 1/2 of the coupler length.

(3) Cutting Thread on the upsetting rebar end with the Rebar Threading Machine.

Then splice the upset reinforcing bars.

(1) Shift two threaded rebars to the steel bar coupler position, ensure the male thread and female thread can be touched.

(2) Rotate the steel coupling, until these two rebar ends are touched to each other, then tighten rebar with torque spanner or socket wrench.
