Abstract

A flat steel anchor for a pre-cast concrete component is comprised of an anchoring portion to be positioned within the concrete component and a connecting portion protruding from the concrete component. The anchoring portion has lateral bars that enclose therebetween a first opening with a first opening cross-section in a plane of the flat steel anchor. The lateral bars are oppositely bent relative to one another and relative to the plane of the flat steel anchor. The respective outer curved planes of the lateral bars form anchoring surfaces of the anchoring portion. The first opening has a second opening cross-section in a plane perpendicular to the plane of the flat steel anchor defined by respective inner curvatures of the lateral bars. The connecting portion has a second opening for receiving a lifting device.
