This structural roof expansion joint detail connects a framing beam per plan to a supporting grid line with a sliding bearing assembly. A continuous 3/8-inch by 15-inch plate is welded to the beam using three-inch quarter-inch fillet welds at each side. A continuous bent plate measuring 5/16-inch by 1-1/2-inch by 8-inch features 13/16-inch by 5-inch slotted holes to accommodate movement. A Con-Serv slide bearing assembly, Type CSA, is placed at each bolt location with upper dimensions of 09CSA 13CS 3 inches by 7 inches and lower dimensions of 09CSA 13CS 3 inches by 8 inches. The assembly is secured using 3/4-inch diameter ASTM A325 bolts at 5 feet on center in standard holes in the beams. A joist per plan with angles measuring L2-1/2 by 2-1/2 by 1/4 at 6 feet on center and L3 by 3 by 1/4 welded to the top and bottom chord supports the 1-1/2-inch deck per plan. Roofing and insulation are provided per the architectural drawings.
