Published: — with international search report (Art. 21(3)) W O 20 17 / 18 1244 Al (54) Title: AJUSTABLE COMPACT JACKING COUPLER AND METHOD OF USE (57) : A self-centring compact coupler for lifting, jacking or pushing apart and positioning concrete elements via their reinforcement bars (rebar) comprising an adjusting coupler member screwed on a threaded post attached to one rebar to apply a lifting or pushing force against a non-adjustable seating stud with an integral seating head and centring protrusion fixed to a corresponding and opposite rebar. An enclosing coupler member screwed on the adjusting coupler member to enclose and lock the seating head and couple the rebar. The unitary configuration of the seating stud and seating head reduces the number of parts with the attendant possibility of individual component failure or slippage. The centring facility negates need of large internal tolerances to accommodate rebar misalignment, thus substantially ensuring co axial transfer of force from the coupler to the rebar. The coupler used to incrementally vary and accurately adjust the relative positions of the concrete elements ---4 to one another in the building process. A modified embodiment of and a method of use of the coupler. -2a - 1 a FIGURE 1
