Abstract: A combination of an anchor rail with a hammer head element for setting in concrete. In order to achieve the best possible load-carrying capacity in the longitudinal direction L of the anchor rail, the anchor rail has toothing, specifically in a region close to a slot-like opening for the insertion of the hammer head element. The hammer head element, in a force-free state, rests only on the toothing and comes to rest over an entire head upper side only in the case of increased tensile forces, as a result of which the force transmission moves outwards to side walls of the anchor rail. This facilitates the load-carrying capacity of the anchor rail with respect to tensile forces.

Abstract: An anchor channel of C-shaped cross-section for embedding in concrete, wherein a lip which adjoins the slot-like opening has been reinforced. In order to achieve high holding forces against withdrawal of a hammerhead element, a setting angle assumes a maximum value in a region that is located closer to the side wall than to the opening.

Abstract: A method for producing a profile from a sheet-metal strip is disclosed. The sheet-metal strip is bent at least twice during a first stage, where, as viewed in the cross-section of the sheet-metal strip, a center section as well as two flank sections are formed, which project angularly from two opposing end regions of the center section. During a second stage following the first stage, the center section is compressed by two complementary roller arrangements which engage on the two opposing end regions of the center section, and the sheet-metal strip is thereby locally thickened.
