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: For stable anchoring of an anchor channel in concrete, an anchor, the anchor shank of which has a larger diameter than an anchor hole of a C-profile channel of the anchor channel, is inserted through the anchor hole from the inside, so that the anchor shank widens the anchor hole and holds the C-profile channel clamped on the anchor shank. An anchor head configured as a countersink head bears internally against a protrusion of the C-profile channel, and on the outer side of the C-profile channel knurling holds the anchor in addition to the clamped fit.
