Abstract

A rail assembly is provided, suitable for embedding in concrete, including a profile rail having a rail body, wherein the rail body has a first lateral wall, a second lateral wall, a first rail lip protruding from the first lateral wall, and a second rail lip protruding from the second lateral wall. The rail assembly has a reinforcing element with a force-absorbing body, wherein the force-absorbing body is positioned in front of the first lateral wall of the profile rail for contacting the first lateral wall of the profile rail with the force-absorbing body. A construction body having a concrete element, in which a rail assembly of this type is embedded is also provided.

First claim

What is claimed is:

1. A rail assembly, suitable for being cast into concrete, comprising:
a profile rail having a rail body, the rail body having a rail bottom, a first lateral wall, a second lateral wall, a first rail lip projecting from the first lateral wall, and a second rail lip projecting from the second lateral wall;
a reinforcing element contacting the rail bottom and having a force-absorption body, the force-absorption body being arranged in front of the first lateral wall of the profile rail over a length of at least 50% of the length of the profile rail in order for the first lateral wall of the profile rail to contact the force-absorption body, the reinforcing element including at least one reinforcing rib protruding perpendicularly to the force-absorption body in a plane spanned by the first and second rail lips; and
at least one force-dissipating rod connected to the reinforcing element;
wherein the reinforcing element has an eyelet element arranged on the force-absorption body, the eyelet element contacting the rail bottom and wherein the profile rail includes an anchor projecting on the rail body, the eyelet element having at least one passage for the anchor.

2. The rail assembly as recited in claim 1 wherein the force-absorption body is a plate.

3. The rail assembly as recited in claim 1 wherein the profile rail includes a further anchor projecting on the rail body.

4. The rail assembly as recited in claim 1 wherein the reinforcing element is connected to the profile rail.

5. The rail assembly as recited in claim 1 wherein the force-absorption body has a same length as the first lateral wall.

6. The rail assembly as recited in claim 1 wherein the at least one force-dissipating rod includes at least two force-dissipating rods connected to the reinforcing element.

7. The rail assembly as recited in claim 1 wherein the at least one force-dissipating rod includes at least three force-dissipating rods connected to the reinforcing element.

8. The rail assembly as recited in claim 1 wherein the at least one force-dissipating rod is directly connected to the force-absorption body.

9. The rail assembly as recited in claim 1 wherein the at least one force-dissipating rod intersects the rail body beneath the rail bottom.

10. The rail assembly as recited in claim 1 wherein the at least one force-dissipating rod intersects the rail body beneath the rail bottom perpendicularly to a lengthwise direction of the rail body.

11. A building structure comprising a concrete element and the rail assembly as recited in claim 1 , the rail assembly being embedded in the concrete element.

12. The building structure as recited in claim 11 wherein the reinforcing element emerges on a surface of the concrete element.
