Epoxy Coated 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 Coupler, Transition Coupler and more.
Epoxy Coated Rebar Coupler is designed to splice epoxy-coated reinforcing bar which is used in place of plain reinforcing bars to protect against corrosion. It is mainly used in bridges, reservoirs, parking structures, pavement, marine structures, and repair work.
The normal one is used to connect rebar with right-handed thread, and the same diameter. It is mostly adopted under Base Slab and middle section of R.C. Column.

Product Advantage
-
Good performance of anticorrosion
-
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.

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, you should process thread on rebar end with the Rebar Threading Machine, ensure these two rebar threaded sectors with right-handed thread and the same diameter.
Then splice these two rebar threaded sectors.
(a) Rotate the coupler to one rebar threaded sector.
(b) Screw the other rebar threaded sector into the coupler, ensure these two rebar ends are touched to each other.
(c) Rotate the coupler reversely, adjust to ensure the exposedly effective threads of two sides are the same and not more than 2P.
(d) Tighten rebar with torque spanner or socket wrench.
