Zusammenfassung:A system for a strand-to-threadbar coupler block for prestressed concrete is disclosed. A system includes a concrete member, one or more multi-wire strands disposed within the concrete member, and a strand-to-threadbar coupler block disposed within the concrete member. The strand-to-threadbar coupler block is formed with a threadbar opening to admit a threadbar, and with one or more strand openings. The system includes one or more strand chucks coupled to the strand-to-threadbar coupler block at the one or more strand openings. A chuck diameter for the one or more strand chucks is greater than a diameter for the one or more strand openings, and the one or more multi-wire strands extend through the one or more strand openings and engage the one or more strand chucks.
