CHALLENGE

Originally designed as a cast-in-place project, Haywood Concrete Products made a proposal to the developer that by using precast load bearing panels manufactured at their plant, they could deliver the finished product to site and install in a fraction of time it would take poured-in-place. Structural load bearing precast panels requiring a continuous rebar splice connection between floors, with the ability to meet tight restrictions on how tall the panels can be for transportation.

SOLUTION

D410 Sleeve Lock Grout Sleeves were used at the bottom of each panel to connect the structural rebars from the panel below it. Once in place and grouted, the Sleeve Lock couplers provided continuous rebar connection from the 6th floor of the building all the way to the 21st. Since the panels were too tall to transport with rebar protruding out of the top, Haywood precast utilized the Dayton Superior DB/DI rebar splice bars with the D101A Dowel bars being placed flush with the top of the panel. Once on site, D101 Dowel-Ins were installed to finish the splice from one panel to the other.
