An elevator pit wall connects to a concrete slab-on-grade and a reinforced concrete footing with continuous vertical and horizontal steel reinforcing bars. The concrete slab-on-grade features number four reinforcing bars spaced at sixteen inches on center. The footing contains number five top and bottom reinforcing bars placed each way with a three-inch minimum cover. An L8x4x1/2 by ten-inch angle acts as an elevator rail support, anchored by two three-quarter-inch by six-inch heavy stud anchors at five-inch gauge and two half-inch diameter by six-inch deformed bar anchors at nine-inch gauge. Vertical wall reinforcement matches the dowels from the footing and extends upward with staggered bar lengths at construction joints.
