DETAILED DESCRIPTION

[0034] A first embodiment of a rail assembly according to the invention is shown in FIGS. 1 to 3; in FIG. 1 as part of a building structure according to the invention.

[0035] The rail assembly comprises a profile rail 2 and a reinforcing element 4 for the profile rail 2. The profile rail 2 comprises a rail body 20 having a first lateral wall 21, a second lateral wall 22, a first rail lip 23, a second rail lip 24 and a rail bottom 25. The first rail lip 23 is arranged at an upper end of the first lateral wall 21 and a second rail lip 24 is arranged at an upper end of the second lateral wall 22, the first rail lip 23 projecting from the first lateral wall 21 toward the second lateral wall 22 and the second rail lip 24 projecting from the second lateral wall 22 toward the first lateral wall 21. A rail slot 26 is formed between the two rail lips 23 and 24. A hammer head element can be inserted into the interior of the rail body 20 through said rail slot 26 and can be secured there by rotation on the rail lips 23 and 24. The rail bottom 25 connects the two lateral walls 21 and 22 on the underside of the rail. In the embodiment shown, the two lateral walls 21 and 22 extend in parallel with one other and the rail bottom 25 is V-shaped. In principle, however, other embodiments are also conceivable, for example with a level rail bottom.

[0036] The profile rail 2 is designed as an anchor rail and as such comprises a plurality (in this case two) of anchors 29 which protrude downwards from the rail body 20. In the present embodiment, the anchors 29 are arranged on the rail bottom 25 by way of example, but other, for example lateral, arrangements are also conceivable.

[0037] The reinforcing element 4 is used to transversely reinforce the first lateral wall 21 and the first rail lip 23 of the profile rail 2. The reinforcing element 4 comprises a planar force-absorption body 41 which is arranged immediately in front of the first lateral wall 21 for contact with the first lateral wall 21. In the embodiment shown, the force-absorption body 41 is substantially the same length as the first lateral wall 21 and thus the profile rail 2. The reinforcing element 4 further comprises a reinforcing rib 47 which protrudes, at the top of the force-absorption body 41, rectilinearly from the force-absorption body 41, in particular away from the rail body 20. The planar reinforcing rib 47 lies in particular in a plane 97 spanned by the rail lips 23 and 24. The rail slot 26 also lies in this plane 97. The reinforcing rib 47 and the force-absorption body 41 are integral here, by way of example.

[0038] The rail assembly further comprises a plurality (in this case three) of force-dissipating rods 45 which are indirectly or directly connected to the reinforcing element 4, in particular to the force-absorption body 41 thereof. Said force-dissipating rods 45 extend approximately in parallel with one another and intersect the rail body 20 beneath the rail bottom 25, preferably at right angles.

[0039] In the embodiment shown, the reinforcing element 4 further comprises an eyelet element 49, by means of which the reinforcing element 4 is attached to the profile rail 2. Said eyelet element 49 is arranged on the force-absorption body 41 and has at least one passage through which an anchor 29 is guided. By means of a nut screwed onto the anchor 29, the eyelet element 49 is pressed against the rail body 20. As a result, the eyelet element 49 and thus the reinforcing element 4 is secured to the profile rail 2. In the embodiment shown, the eyelet element 49 is formed as an angled plate that is integral with the force-absorption body 41. In principle, however, other embodiments of the eyelet element 49 are also conceivable or, as shown for example in FIG. 4, embodiments without an eyelet element 49 are conceivable.

[0040] The rail assembly can be cast into a concrete element 1 in the building structure shown in FIG. 1. The rail assembly is in this case arranged such that the rail lips 23 and 24, the rail slot 26 and the reinforcing rib 47 emerge on the same surface of the concrete element 1. The anchor 29 and the at least one force-dissipating rod 45 are embedded in the concrete element 1.

[0041] If, in the building structure shown in FIG. 1, transverse forces occur in the first rail lip 23 in the direction of the first lateral wall 21, these can be at least partially diverted from the first lateral wall 21 to the force-absorption body 41 resting against the first lateral wall 21, the reinforcing element 4 reinforcing the force-absorption body 41. The force-dissipating rods 45 allow at least partial introduction of the dissipated forces deep into the concrete element 1, as a result of which the load on the edge of the concrete element 1 lying in front of the profile rail 2 and the reinforcing element 4 can be relieved.

[0042] The other embodiments shown in the figures are based substantially on the embodiment in FIGS. 1 to 3, and therefore only the substantial differences will be discussed below.

[0043] The embodiment of FIG. 4 is a modification of the embodiment of FIGS. 1 to 3, in which the eyelet element 49 is missing. In contrast with the embodiment of FIGS. 1 to 3, in which the reinforcing element 4 is Z-shaped, the reinforcing element 4 is L-shaped in the embodiment of FIG. 4.

[0044] In the embodiment of FIGS. 5 and 6, the reinforcing element 4 has an additional rib 81 which connects the force-absorption body 41 and the reinforcing rib 47 such that the additional rib 81, the force-absorption body 41 and the reinforcing rib 47 form a triangular hollow profile. The reinforcing element 4 can in this case be attached to the profile rail 2 via end caps 82 which engage in the interior of the rail body 20 and in the triangular hollow profile of the reinforcing element 4.

[0045] In the embodiment of FIG. 7, the reinforcing element 4 is designed as an annular plate which surrounds the rail body 20.

[0046] In the embodiment of FIG. 8, the force-absorption body 41 is formed as a rod which is integral with two force-dissipating rods 45. The reinforcing element 4 is connected to the profile rail 2 by means of clamps 88 which each act on a force-dissipating rod 45 and an anchor 29.

[0047] The embodiment of FIG. 9 is based on the embodiment of FIG. 4, but the force-dissipating rods 45 are designed differently. In particular, in the embodiment of FIG. 9 two force-dissipating rods 45 are provided which form the legs of a U-profile into which the reinforcing element 4 is centrally inserted.
