Extended Upsetting Coupler

Description

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.

Extended Upsetting Coupler is designed for long, large, and dense upsetting bars being installed on site, and it is not convenient to rotate the re-bars. The Extended Rebar Coupler is longer than the normal steel upsetting couplings.

Technical Parameters

Product Advantage

Raw material-saving, high energy saving, high work efficiency.
Construction Environmental Protection. no flame, no noise pollution.
It is not be affected by the chemical compositions and types of reinforced bars and won’t be influenced by weather and work-site.
Low cost, simple operation.
Can be prefabricated and the construction period can be shortened.
High dimension precision, reliable quality and Stable performance.
High strength. The tensile strength usually more than 600 Mpa, it can reach 110% of yield strength of parent rebar.
After 2 million times of fatigue strength test, the connection is in good condition.
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 right-handed thread and the same diameter.

(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 the extended upsetting coupler to the longer rebar threaded sector.

(2) Rotate the coupler onto the longer rebar threaded sector. Then shift these two rebar threaded sectors close to each other, ensure two rebar threaded end can be touched.

(3) Rotate the coupler onto the shorter rebar threaded sector side. Then tighten rebar with torque spanner or socket wrench.
