This is a unique specialization/improvement of a standard precast concrete rebar splicing method. The slab rebar is spliced much like the conventional pour strip, thus requiring only minimal reinforcing adjustment and only in the bay of the coupler. This type of rebar splicing has had a long and successful track record in both the precast industry and in coupling congested rebar in cast-in-place columns. The unique design of the PS=Ø® coupler accommodates the dynamic movement caused by the post-tensioning compression forces in the slabs.
