Abstract

The invention relates to an anchor rail arrangement with a concrete body which has two end faces which extend at an angle to one another and meet at an outer edge, and with two anchor rails which are embedded in the concrete body, wherein the two anchor rails each have a rail body with a longitudinal slot, wherein the longitudinal slot of the first rail body emerges on the first end face and the longitudinal slot of the second rail body emerges on the second end face on the concrete body, and wherein the two longitudinal slots extend in a common rail plane, wherein the first anchor rail has a plurality of first anchor bodies arranged on the first rail body, namely a first anchor body closest to the edge and at least one further first anchor body, and wherein the second anchor rail has a plurality of second anchor bodies arranged on the second rail body, namely a second anchor body closest to the edge and at least one further second anchor body. According to the invention, the first anchor body closest to the edge is a headless anchor bar and the second anchor body closest to the edge likewise is a headless anchor bar.

First claim

What is claimed is:

1. An anchor rail arrangement for a concrete body having a first front surface and a second front surface that meet at an adjoining outer edge of the concrete body, the anchor rail arrangement comprising:
a first anchor rail embedded in the concrete body, the first anchor rail comprising:
a first rail body embedded in the first front surface of the concrete body such that a first longitudinal slot of the first rail body is accessible from the first front surface of the concrete body; and
a plurality of first anchor bodies mounted on the first rail body; and

a second anchor rail embedded in the concrete body, the second anchor rail comprising:
a second rail body embedded in the second front surface of the concrete body such that a second longitudinal slot of the second rail body is accessible from the second front surface of the concrete body; and
a plurality of second anchor bodies mounted on the second rail body;

wherein the first longitudinal slot and the second longitudinal slot align along a common rail level for the first front surface and the second front surface;
wherein a first anchor body of the plurality of first anchor bodies, that is closest to the adjoining outer edge of the concrete body, comprises a first headless anchor rod,
wherein a second anchor body of the plurality of second anchor bodies, that is closest to the adjoining outer edge of the concrete body, comprises a second headless anchor rod, and
wherein the first headless anchor rod is angled at least once to permit the first headless anchor rod and the second headless anchor rod to cross and retain the common rail level of the first anchor rail and the second anchor rail.

2. The anchor rail arrangement of claim 1 , wherein:
the first anchor rail and the second anchor rail are two separate parts; and
the first anchor rail is not welded to the second anchor rail.

3. The anchor rail arrangement of claim 1 , wherein:
the first headless anchor rod comprises a first reinforcing bar; and
the second headless anchor rod comprises a second reinforcing bar.

4. The anchor rail arrangement of claim 1 , wherein the first headless anchor rod is angled twice so that a first section of the first headless anchor rod is parallel to, but offset from a second section of the first headless anchor rod.

5. The anchor rail arrangement of claim 1 , wherein:
the first headless anchor rod comprises threads that permit the first headless anchor rod to be connected to a bushing by screwing the first headless anchor rod into the bushing, and
the bushing comprises threads that permit the bushing to be connected to the first rail body by screwing the bushing into the first rail body.

6. The anchor rail arrangement of claim 1 , wherein:
the first rail body comprises a first crosspiece along a first edge of the first longitudinal slot and a second crosspiece along a second edge of the first longitudinal slot;
wherein the first crosspiece and second crosspiece are configured to receive a head of a T-head bolt inserted between the first crosspiece and the second crosspiece, and engage the head of the inserted T-head bolt when the T-head bolt is turned after being inserted.

7. An anchor rail installation, comprising
a concrete body comprising a first surface having a first outer edge, and a second surface having a second outer edge, wherein the first surface is angled with respect to the second surface, and wherein the first outer edge of the first surface abuts the second outer edge of the second surface to form an outer edge of the concrete body;
a first anchor rail embedded in the concrete body, the first anchor rail comprising:
a first rail body embedded in the first surface of the concrete body such that a first longitudinal slot of the first rail body is accessible from the first surface of the concrete body; and
a plurality of first anchor bodies mounted on the first rail body; and

a second anchor rail embedded in the concrete body, the second anchor rail comprising:
a second rail body embedded in the second surface of the concrete body such that a second longitudinal slot of the second rail body is accessible from the second surface of the concrete body; and
a plurality of second anchor bodies mounted on the second rail body;

wherein the first longitudinal slot and the second longitudinal slot align along a common rail level for the first surface and the second surface;
wherein a first anchor body of the plurality of first anchor bodies, that is closest to the outer edge of the concrete body, comprises a first headless anchor rod, and
wherein a second anchor body of the plurality of second anchor bodies, that is closest to the outer edge of the concrete body, comprises a second headless anchor rod.

8. The anchor rail installation of claim 7 , wherein:
the first anchor rail and the second anchor rail are two separate parts; and
the first anchor rail is not welded to the second anchor rail.

9. The anchor rail installation of claim 7 , wherein:
the first headless anchor rod comprises a first reinforcing bar; and
the second headless anchor rod comprises a second reinforcing bar.

10. The anchor rail installation of claim 7 , wherein the first headless anchor rod and the second headless anchor rod cross.

11. The anchor rail installation of claim 7 , wherein the first headless anchor rod is angled at least once to permit the first headless anchor rod and the second headless anchor rod to cross and retain the common rail level of the first anchor rail and the second anchor rail.

12. The anchor rail arrangement of claim 7 , wherein the first headless anchor rod is angled twice so that a first section of the first headless anchor rod is parallel to, but offset from a second section of the first headless anchor rod.

13. The anchor rail arrangement of claim 7 , wherein:
the first headless anchor rod comprises threads that permit the first headless anchor rod to be connected to a bushing by screwing the first headless anchor rod into the bushing, and
the bushing comprises threads that permit the bushing to be connected to the first rail body by screwing the bushing into the first rail body.

14. The anchor rail arrangement of claim 7 , wherein:
the first rail body comprises a first crosspiece along a first edge of the first longitudinal slot and a second crosspiece along a second edge of the first longitudinal slot;
wherein the first crosspiece and second crosspiece are configured to receive a head of a T-head bolt inserted between the first crosspiece and the second crosspiece, and engage the head of the inserted T-head bolt when the T-head bolt is turned after being inserted.

15. An anchor rail installation, comprising
a concrete body comprising a first vertical surface having a first vertical edge and a second vertical surface having a second vertical edge, wherein the first vertical surface is angled with respect to the second vertical surface, and wherein the first vertical edge of the first vertical surface abuts the second vertical edge of the second vertical surface to define a corner of the concrete body;
a first rail body embedded in the first vertical surface of the concrete body such that a first longitudinal slot of first rail body horizontally traverses at least partially across the first vertical surface and is accessible from the first vertical surface of the concrete body;
a second rail body embedded in the second vertical surface of the concrete body such that a second longitudinal slot of second rail body horizontally traverses at least partially across the second vertical surface and is ac
