About this detail

A reinforced concrete elevator pit wall bears on a continuous concrete footing, intersecting with a concrete slab-on-grade at the top. The concrete footing features top and bottom reinforcing bars consisting of number five bars spaced at twelve inches on center each way, maintained with a three-inch minimum concrete cover. The vertical and horizontal wall reinforcement ties into dowels matching the wall reinforcement above, set with a one-quarter-inch typical roughened surface. At the top wall corner, an L4x3x1/4 angle with one-half-inch diameter by six-inch heavy-duty sleeve anchors at sixteen inches on center is provided as needed for elevator sill attachment. The slab-on-grade transitions with number four reinforcing bars spaced at sixteen inches on center. A reference note directs to detail six on sheet S502 for the sump pit if present.
