536. Free CAD Download: Cantilevered Porch Roof Detail

This CAD drawing presents a detailed cross-section (SCALE 1:50) of a cantilevered entrance porch roof extending from a building at elevation +6.100. The roof construction comprises a top finish of cement mortar spray (#75) with a white exterior paint, reinforced with a wire mesh layer. The primary support structure consists of 30×60 mm rectangular steel purlins spaced at 575 mm centers, spanning across circular steel pipe supports (Ø350, Ø300, Ø220, Ø160) interconnected via welded or bolted connections.

An integrated railing system runs along the porch edge, featuring designed steel profile posts and 30×60 mm rectangular steel horizontal rails. The railing includes a hook/bracket detail, a white aluminum cover for aesthetic and protective purposes, and a Ø6 cable as a top element.

The drawing provides comprehensive dimensional information, including purlin spacing, overall porch roof projection (4600mm), and component heights. The connection detail to the main building structure is partially illustrated. This technical section clearly defines the layered construction, steel framework, railing design, and integration with the building for this entrance porch roof.
