About this detail

A concrete roof curb is detailed over a sloped metal deck and fill assembly at a 21.50 degree slope. The curb is reinforced with two number five bars at the top, along with deformed bar anchors featuring a Class B lap matching the size and spacing of the deck reinforcement. Where interrupted by a column, deformed bar anchors with a Class B lap are provided. A three-eighths-inch bent plate with an eight-inch horizontal leg lines the curb alongside one-half-inch diameter deformed bar anchors spaced at twelve inches on center. Angle sections measuring L3x3x1/4 by six inches long are attached at both ends with three-sixteenths-inch fillet welds on three sides of each leg against the column beyond.
