About this detail

Floor perimeter blocking at a penthouse level frames insulated metal wall panels against structural steel wide flange beams and hollow structural section backing posts. An HSS8x8x1/2 or HSS8x4x1/4 backing post spaced at eight feet on center supports the wall panels, tied back with a 1-inch maximum gap and connected using 3/16-inch fillet welds and a 1-inch diameter ASTM A325 bolt in a longitudinal slotted hole. Two 3/4-inch diameter high-strength bolts secure angles to the beam, with 1/4-inch fillet welds typical at the angle-to-beam connections. Shotpins spaced at 4 inches on center fasten members where applicable, and 3/8-inch plates are welded to each side of the HSS5x5 support. Double angle braces (2L3x3x1/4) at eight feet on center max provide diagonal bracing, featuring clipped or rounded corners at work points. A note indicates that insulated metal wall support is a delegated design under a deferred submittal.
