(1) The invention is explained in greater detail in the following with reference to preferred embodiments, which are shown schematically in the accompanying drawings, it being possible to implement individual features of the embodiments shown in the following in principle individually or in any desired combination within the context of the invention. In the drawings, shown schematically:

(2) FIG. 1 is a perspective view of a structure according to the invention comprising a concrete body and a profiled rail assembly according to the invention, the concrete body being shown as transparent;

(3) FIG. 2 is a side view of the profiled rail assembly from FIG. 1 prior to casting of the concrete body; and

(4) FIG. 3 is a perspective view similar to FIG. 1 of a modified embodiment of a structure according to the invention comprising a concrete body and comprising two profiled rail assemblies according to the invention arranged at angles.

DETAILED DESCRIPTION

(5) A first embodiment of a structure according to the invention comprising a profiled rail assembly according to the invention is shown in FIG. 1. The body structure comprises a concrete body 10 having a first surface 11 (the upper face in FIG. 1) and a second surface 12 (the left side face in FIG. 1), the second surface 12 extending perpendicularly to the first surface 11 in this case. An edge 13 is formed at the transition between the first surface 11 and the second surface 12.

(6) The structure further comprises a profiled rail assembly, which in turn has a profiled rail 20 designed as an anchor rail and a reinforcing body 40. The profiled rail 20 has a C-shaped rail body 25 with a rail slot 26 which extends in the direction of the longitudinal axis 99 of the profiled rail 20, i.e. the long extension extends in parallel with the longitudinal axis 99 of the profiled rail 20. The rail body 25 is undercut at the rail slot 26. An elongate hammer head element can therefore be inserted into the rail body 25 through the rail slot 26 and fixed to the rail body 25 by rotation about an axis extending perpendicularly to the longitudinal axis 99 of the profiled rail 20. The profiled rail 20 also comprises a plurality (in this case two, by way of example) of anchors 30 which protrude from the rail body 25 on a rear face of the rail body 25 opposite the rail slot 26.

(7) The profiled rail 20 is embedded in the concrete body 10, specifically in such a way that the profiled rail 20 emerges, with its rail slot 26, on the first surface 11 of the concrete body 10. The longitudinal axis 99 of the profiled rail 20 preferably extends in parallel with the above-mentioned edge 13 of the concrete body 10.

(8) The reinforcing body 40 has a planar head element 41 and a plurality of elongate, preferably rod-shaped tension elements 44, which protrude from the rear face of the head element 41. The reinforcing body 40 emerges, with its head element 41, on the second surface 12 of the concrete body 10, specifically with a front-face contact surface 43. At this contact surface 43, the head element 41 comes into contact with a formwork element for the concrete body 10 before the casting of the concrete body 10. By means of fasteners (not shown), such as nails, which are passed through through-openings 42 in the head element 41, the head element 41 is fixed in this position on the formwork element.

(9) The head element 41 of the reinforcing body 40 has, with regard to the direction of the longitudinal axis 99, a greater length than the profiled rail 20, the reinforcing body 40 completely covering the rail body 25, with regard to the direction of the longitudinal axis 99 of the profiled rail 20, i.e. the opposite ends of the profiled rail 20 are within or at least on the ends of the head element 41, with regard to the direction of the longitudinal axis 99 of the profiled rail 20.

(10) The reinforcing body 40 is arranged so that the contact surface 43 of its head element 41 extends in parallel with the second surface 12 of the concrete body 10, perpendicularly to the first surface 11 of the concrete body 10 and/or perpendicularly to a slot plane 27 spanned by the rail slot 26 and extending in the first surface 11. When viewed perpendicularly to the longitudinal axis 99, i.e. in the viewing direction implemented in FIG. 2, the tension elements 44 extend between the anchors 30 and intersect the anchors 30.

(11) The reinforcing body 40 reinforces the concrete body 10 in the region of the edge 13 and can in particular counteract premature breakage of the concrete body 10 in the case of transverse loads in the profiled rail 20, in particular in the case of loads directed toward the second surface 12 perpendicularly to the longitudinal axis 99.

(12) To further improve the transverse load absorption, the profiled rail 20 may optionally have a stiffening element 60 which is angled, for example, and which stiffens the side wall of the rail body 25 nearer the edge 13.

(13) FIG. 2 shows the profiled rail assembly with the profiled rail 20 and the reinforcing body 40 before casting into the concrete body 10. As FIG. 2 shows, before casting, the reinforcing body 40 and the profiled rail 20 are already in the same arrangement relative to one another which is also maintained after casting. In order that the reinforcing body 40 and profiled rail 20 reliably remain in this arrangement during installation of the profiled rail assembly, the reinforcing body 40 is preferably already fixed to the profiled rail 20 before casting the profiled rail assembly. In the present embodiment, this fastening is implemented on the tension elements 44, which are fastened, for example, to the anchors 30 or the rail body 25, in particular to the rear face of the rail body 25, for example are welded thereto.

(14) FIG. 3 shows a modification of the structure of FIG. 1 close to the corner. In the embodiment of FIG. 3, in addition to the profiled rail assembly described above, a second profiled rail assembly having a second profiled rail 20 and a second reinforcing body 40 is provided, the two profiled rail assemblies being arranged on the concrete body 10 at 90 relative to one another. The longitudinal axes of the two profiled rails 20 and 20 are perpendicular to one another and the two reinforcing bodies 40 and 40 emerge on different surfaces.
