Standard Rebar Coupler

Description

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 Rebar Coupler and more.

Standard Rebar Coupler is designed to splice rebars with the same diameter, and at least one rebar is not limited to the rotation and axial movement. The coupler has a single right-handed female thread from one side to the other. Each end of the inner hole has the moderate chamfer.

It is mostly adopted under Base Slab and middle section of R.C. Column.

The epoxy-coated coupler is available.

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

Cartons & Wooden Pallets or Wooden Cases. Products also can be packed according to customers’ 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, you should process the thread on the rebar end with the Rebar Thread Rolling Machine, ensure these two rebar threaded sectors with right-handed thread and the same diameter.
