About this detail

A steel pipe penetrates a concrete roof slab through a steel pipe sleeve and is secured by a specified pipe clamp connected to angle clips or angle brackets. The angle bracket is anchored to the underside of the roof slab using expansion bolts, two on each end at twelve inches on center typically, or welded directly to the pipe clamp with optional bolted connections on each side. A sixteen gauge sheet metal collar and watertight seal surround the pipe above the roof line, complemented by an aluminum jacket over required insulation. Roofing and flashing tie into the assembly according to architectural drawings.
