About this detail

Concrete is chipped away to expose existing slab reinforcement and the steel beam web, ensuring existing bars remain undamaged. New rebar couplers splice into the cut slab reinforcement to match the existing size and spacing. Number 6 epoxy dowels with twelve-inch embedment at six inches on center tie into the wall, supplemented by number 6 welded deformed bar anchors at six inches on center. The assembly incorporates specific clearances including three-inch minimum and six-inch maximum dimensions, with shoring provided for the existing slab as required.
