Position Rebar Coupler

Project Description

Position Rebar Coupler

Specifications

Aleono Rolling Parallel Thread Rebar Coupler is designed to produce a full strength mechanical joint between reinforcing bars. 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 Rebar Coupler, Position Rebar Coupler,  Transition Coupler and more.

position coupler operationPosition Rebar Coupler is also known as Left-handed & Right-handed Rebar Coupler, it is designed to splice two rebars when both of them can not be rotated but at least one of them can be moved axially. The 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.

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.

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, you should process thread on rebar end with the Rebar Threading Machine, 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.

Then splice these two rebar threaded sectors.

splice rebar

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

(b) Rotate the coupler.

(c) During this process, observe whether these two rebar threaded sectors are screwed into the coupler simultaneously. if no, adjust it.

(d) Go on to rotate the coupler, until these two rebar ends are touched to each other. Ensure the exposedly effective threads of two sides are the same and not more than 2P.

(e) Tighten rebar with torque spanner or socket wrench.
