A profiled rail assembly for casting into concrete. The profiled rail assembly includes a profiled rail including a rail body having a rail slot extending in the direction of a longitudinal axis of the profiled rail, and a reinforcing body including a head element and at least one tension element protruding from the head element, the head element opposite the at least one tension element having a head element major face defining a contact surface for a formwork element. The at least one tension element is connected to the profiled rail.

Structure having edge reinforcement on profiled rail

A structure is provided, including a concrete body having a first surface and having a second surface arranged at an angle to the first surface; a profiled rail embedded in the concrete body, the profiled rail having a rail body having a rail slot extending in the direction of the longitudinal axis of the profiled rail, and the profiled rail emerging on the first surface of the concrete body; and a reinforcing body, which emerges on the second surface of the concrete body and which overlaps with the rail body, with regard to the direction of the longitudinal axis of the profiled rail, at least in some regions. A profiled rail assembly for such a structure is also provided.

A spreading anchor (1) including an anchor rod (2) provided at its front end, when viewed in a setting direction, with a head (3, 30) having at least several regions, which taper outwardly in the setting direction, and extending through an axial through-bore of an expansion sleeve(5) axially displaceable along the anchor rod (2, 20) and having a plurality of axial longitudinal slots (7) extending from a front end of the expansion sleeve (2, 20) and forming at least two, located opposite each other expansion tabs (6) provided at their free front ends with cutters (16), the spreading anchor (1) being supported against an upper surface of a ground (G) and further including rotation-transmitting driver elements for transmitting axial rotation, which is generated during setting of the anchor rod (2, 20), to the expansion sleeve (5).
