Patent ID: 11492794

Abstract:
A flange connector is embedded in precast concrete structural member for use in joining adjacent concrete members together, wherein the flange connector is characterized by a center plate and legs extending back from each side of the center plate. Each of the legs is provided with projections extending from the top edge and bottom edge of the leg, in the same plane defined by the height and length of the leg. The projections extending from the top edge and the bottom edge of the leg may be mirror images of each other, so that the cross-sectional area of the leg is substantially the same over the portion of the leg with the projections. The legs of the flange connector may incorporate additional enhancements to increase the resistance to pull out, including a neck formed by notches in the top and bottom of each leg, adjacent the transition region extending from the center plate and one or more embossments creating a convex area on one side of each leg and a concave area on the opposite side of each leg.
