About this detail

A roof screenwall assembly features an HSS6x6 column anchored to a 1/2-inch base plate over the girder top flange and roof slab. The column extends upward to support an HSS6x4 beam at the top of the screenwall, with a continuous 14-gauge by 10-inch steel plate fastened using 0.157-inch diameter Hilti X-U powder-actuated fasteners spaced at 18 inches on center, staggered. Lateral stability is provided by an HSS4x4x1/4 diagonal brace connected via a 1/2-inch knife plate centered on the beam, brace, and column, secured with 1-inch diameter machine bolts. An additional 8-inch extra-strong pipe post with a 1/2-inch base plate and 1/2-inch x 12-inch x 10-inch plate ties back to the roof slab. Fillet welds of 3/16-inch and 3/8-inch sizes are specified throughout the connection plates.
