DONGYANG Mechanical Coupler

  • Adopt 45# high quality carbon steel
  • Used to splice rebar grade 60 with Dia. 16mm–40mm
  • High splice strength, which could exert 125% of the tensile and compression strength of rebar. Provides full load transfer with the slimmest and shortest coupler possible
  • Quick and easy to install
  • Standard type, right and left threading type and transition type 3 series and more than 50 varieties of products. Being able to satisfy rebar splicing demand of horizontal, vertical, slant and any position

Benefits:

  • No staggering of spliced bars required.
  • Practical alternative to lap splicing.
  • Solves bar congestion problems.
  • Shortens construction cycle time.
  • Reduces steel wastage.

Parallel Thread Rebar splicing with Rolled Thread End:

Rolling after stripping rib:
(1) Cutting off the end of the rebar;

(2) Stripping the ribs at the end of the rebar and rolling thread;
Splicing the rebar by using the coupler.

PRODUCT DATABuilding Code-International Standards

ACI 318:

12.14.3.1-MECHANICAL AND WELDED SPLICES SHALL BE PERMITTED.

12.14.3.2-A FULL MECHANICAL SPLICE SHALL DEVELOP IN TENSION OR COMPRESSION AS REQUIRED AT LEAST 1.25fy OF THE BAR.

UBC 1997:

“Tension tie members shall be made with a full-welded splice or use full mechanical connection:

BS 8110:  1997

“To achieve full strength but joint for a bar in tension requires mechanical connection”

Also conforms to NSCP 412.15.3.2, DIN 488, BS 4449, ASTM A615, ASTM A706, NF A35-016, NEN 6008, NBN A24-302, SIA 162101, GB1499 & I5 1786
