About this detail

A concrete-filled metal deck runs parallel to a concrete masonry unit wall, tied together with a C12x20.7 channel support assembly. A one-inch gap is maintained between the top of the CMU wall and the underside of the deck, filled with a compressible material. The channel is anchored to the wall using a three-eighths-inch thick plate with two half-inch diameter expansion anchors featuring three-and-a-quarter-inch embedment. Two five-eighths-inch diameter by four-inch embedded headed anchor bolts or expansion anchors secure the top plate through two-and-a-half-inch oversized holes, covered by three-and-a-half by three-and-a-half by three-eighths-inch thick plate washers. A quarter-inch fillet weld on three sides connects the plate to the C12x channel. The assembly is placed at each end of the wall and at forty-eight inches on center maximum intermediately.
