When bars of different sizes need to be spliced, it is not always possible to reduce the size of the larger bar end and use a standard coupler. For such cases, the Transition Coupler offers transition couplers that conveniently avoid the difficult task of planning in advance the need of transitions.
It is widely applicable to progressive floor-by-floor diameter reduction of vertical reinforcing bars in high-rise buildings, splicing of different-diameter rebars at beam-column joints, rebar transition between pile foundations and pile caps, diameter variation sections of shear wall edge members, as well as variable-diameter reinforcement scenarios including bridge piers and rail transit structures, covering conventional diameter transition combinations within the range of φ16 mm to φ40 mm.
