DETAILED DESCRIPTION OF THE DRAWINGS

[0037] FIGS. 1 to 3 show an anchoring rail according to the invention, which can be manufactured using a method according to the invention.

[0038] The anchoring rail has a rail body 10 which is approximately C-shaped in cross-section and to which a plurality of anchoring bodies 30 are fastened at a distance from one another. The rail body 10 has two side walls 15 and 16, preferably parallel to each other, which are connected by a rail back 17, wherein the rail back 17 is executed in the present case as V-shaped in cross-section. The anchoring bodies 30 are connected to the rail back 17 of the rail body 10. On the first side wall 15, a first tab 11 protrudes toward the second side wall 16. Accordingly, on the second side wall 16, a second tab 12 protrudes toward the first side wall 15. Between the two webs 11 and 12, a longitudinal slot 13 is formed. Through this longitudinal slot 13, the head of a hammer head screw 9 can be inserted into the interior 14 of the rail body 10, wherein the hammer head screw 9 can then be positively fixed by rotation about its longitudinal axis on the two tabs 11 and 12, which each form an undercut. This fixed state of the hammer head screw 9 is shown in FIG. 3.

[0039] On the rail back 17, i.e., on the side of the rail body 10 which is opposite the longitudinal slot 13, a plurality of nail holes 18 are provided in the rail body 10, which serve to set the anchoring rail before setting in concrete on a formwork.

[0040] As will be explained in detail below, at least one part of the anchoring bodies 30, preferably all anchoring bodies 30, are each secured to the rail by means of an annular fastening body 40. The fastening bodies 40 are located in the interior 14 of the rail body 10, and are connected to the rail body 10, in particular with its rail back 17, as well as to the respective anchoring body 30 cohesively, in particular welded. In particular, the anchoring rail has common weld seams 111, preferably laser beam weld seams, which adjoin the respective anchoring body 30, the respective fastening body 40 and the rail body 10.

[0041] As FIG. 3 shows in particular, the anchoring bodies 30 each have an anchor head 31 arranged outside the rail body 10 and an anchor foot 32 arranged in the interior 14 of the rail body 10. The anchor head 31 preferably forms a local cross-sectional widening. The cohesive connection of the anchoring body 30 with the fastening body 40 is formed on the anchor foot 32.

[0042] FIGS. 4 to 8 show a sequence of stages in a first embodiment of a manufacturing method for an anchoring rail according to FIGS. 1 to 3.

[0043] In the method variant of FIGS. 4 to 8, as shown in FIG. 4, the rail body 10 is initially provided with, at least one passage opening 19 in the rail back 17. The passage opening 19 extends from the outside of the rail body 10 into the interior 14 of the rail body 10 and is preferably circular.

[0044] Then, as shown in FIG. 5, an anchoring body 30 is passed through the passage opening 19 of the rail body 10. The anchor foot 32 of the anchoring body 30 is then located in the interior 14 of the rail body 10 and the anchor head 31 of the anchoring body 30 outside of the rail body 10. In particular, the anchoring body 30 can be inserted from the outside into the rail body 10, that is, the anchoring body 30 is in particular with the anchor foot 32 ahead inserted into the passage opening 19 of the rail body 10.

[0045] In the next step, which is shown in FIG. 6, an annular fastening body 40 in the interior 14 of the rail body 10 is attached to the anchoring body 30, namely its anchor foot 32, wherein the anchoring body 30, namely its anchor foot 32, is arranged in an opening 49 of the fastening body 40. Furthermore, the fixing body 40 is brought into contact with the rail body 10, preferably its rail back 17.

[0046] Then, as shown in FIG. 7, a laser beam welding process is performed, in which the anchoring body 30 is integrally connected to the fastening body 40 and the rail body 10. As FIG. 7 shows, a laser beam 100 is preferably directed through the rail body 10 onto the fastening body 40 and/or the anchoring body 30.

[0047] The finished anchoring rail is shown in FIG. 8. As can be seen there, the rail body 10, the fastening body 40 and the anchoring body 30 are connected by a common weld seam 111.

[0048] FIGS. 9 to 13 show a sequence of stages in a second embodiment of a production method for an anchoring rail according to FIGS. 1 to 3.

[0049] In the method variant of FIGS. 9 to 13, as shown in FIG. 9, the rail body 10 is initially provided with at least one passage opening 19 in the rail back 17. The passage opening 19 extends from the outside of the rail body 10 into the interior 14 of the rail body 10 and is preferably circular.

[0050] Then, as shown in FIG. 10, an annular fastening body 40 is provided with an opening 49 and arranged in the interior 14 of the rail body 10, that the opening 49 of the fastening body 40 is aligned with the through hole 19 of the rail body 10 and is open to through hole 19 of the rail body 10.

[0051] In the next step, which is shown in FIG. 11, an anchoring body 30 is passed from the outside through the passage opening 19 of the rail body 10 and thereby, in particular with its anchor foot 32, inserted into the opening 49 of the fastening body 40. Even before this step, or afterwards, the fastening body 40 is brought into contact with the rail back 17.

[0052] Then, as shown in FIG. 12, a laser beam welding process is carried out, in which the anchoring body 30 is adhesively bonded to the fastening body 40 and the rail body 10. As FIG. 12 shows, a laser beam 100 is preferably directed through the rail body 10 onto the fastening body 40 and/or the anchoring body 30.

[0053] The finished anchoring rail is shown in FIG. 13. As can be seen there, the rail body 10, the fastening body 40 and the anchoring body 30 are connected by a common weld seam 111.

[0054] Both in the method variant of FIGS. 4 to 8 and in the method variant of FIGS. 9 to 13, the opening 49 of the fastening body 40 is shown as a passage opening. In principle, however, it could also be designed as a blind hole, which is open towards the anchoring body 30.
