About this detail

A concrete loading dock ramp curb and concrete steps on grade include associated reinforcing steel and joint details. The ramp curb features a twelve-inch concrete footing reinforced with three continuous number five rebars and vertical number five rebars with standard hooks at twelve inches on center. The wall stem includes number four horizontal rebars at twelve inches on center, two continuous number four rebars at the top of the wall, and a three-quarter-inch chamfer on exposed corners. A guardrail with a cast-in base is anchored at the top of the wall, and a half-inch thick preformed expansion joint material is provided adjacent to the exterior pavement. The stair on grade has concrete treads and risers reinforced with number five rebars at twelve inches on center each way, a number three nosing bar with one and a half inches of clearance, and a lap splice connecting to the slab-on-ground reinforcement. Dowels consisting of number four bars by eighteen inches long at twelve inches on center tie into the foundation, with an isolation joint separating the stair slab from the adjacent slab-on-ground.
