Precast concrete wall panels meet at a 90-degree corner with an internal joint sealed against the exterior. The panels are connected by hot-dipped galvanized angle sections measuring 8 by 4 by 1/2 inches with a length of 0 feet 10 inches. Each angle is secured with two 1/2-inch diameter Wej-It wedge anchors on each leg, spaced with 2-inch edge distances and a 6-inch intermediate span. Panel reinforcement consists of internal steel bars placed within the panels of thickness t. A bead of sealant is applied at the external corner joint between the adjacent precast panels.
