About this detail

A concrete curb assembly is supported by a concrete-over-metal-deck floor system framing into a hollow structural section or box column with wide-flange beams. The curb features typical reinforcing with number three bars spaced at eighteen inches center-to-center for curb heights under six inches, number four bars at eighteen inches center-to-center for heights between six and twelve inches, and number four bars at twelve inches center-to-center for heights between twelve and twenty-four inches. Additional continuous number four bars are provided when the curb height exceeds twelve inches, with legs turned inward and longitudinal bars moved inside the hook at the deck edge. Two curtains of dowels and number three hairpins matching the vertical spacing are included where indicated, maintaining three-quarters of an inch clear cover. An optional construction joint is detailed at the deck interface. The plan view shows typical wide-flange beams framing around the HSS or box column with typical two-by-two-by-one-eighth-inch angles, which are omitted if the offset is three inches or less.
