About this detail

A roof davit support pedestal assembly features a top plate with a portable socket and a locking socket hole welded to a support post below. The post extends through the finished roof and concrete layers down to the structural framing, utilizing weld plates and structural angles bolted to glue-laminated beams per structural plans. Load criteria specify a one thousand pound working load per OSHA, four thousand pound factored load per OSHA, and three thousand pound live load per California Building Code. The design accounts for sloping structural steel framing where applicable, with post heights varying between four inches minimum and ten inches maximum above the roof surface. Davit reach and orientation angles ranging from zero to ninety degrees relative to the parapet are detailed in plan and section views.
