A ceiling joist framing connection to an existing concrete panel or masonry wall utilizes a continuous L3x3x1/4 angle attached to the wall with 5/8-inch diameter Hilti KB-TZ2 anchors spaced at twenty-four inches on center with four-inch embedment. The joist connects to the angle with a 1/8-inch fillet weld and a two-inch weld length, supported by a 3x3 sixteen-gauge clip angle fastened with two number-ten screws at each leg typically at each ceiling joist. An alternate detail employs Hilti X-U shot pins spaced at twenty-four inches on center to fasten the joist framing directly to the wall.
