Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention will be described in greater detail below making reference to preferred embodiments that are schematically depicted in the accompanying figures. These figures schematically show the following:

(2) FIG. 1: a longitudinal sectional perspective view of an anchor channel according to the invention;

(3) FIG. 2: a cross-sectional view of one of the fastening points of the anchor channel according to FIG. 1, embedded into a concrete part according to the invention; and

(4) FIG. 3: a side view of an anchor channel according to the invention, with a plurality of different additional elements.

DETAILED DESCRIPTION

(5) One embodiment of an anchor channel according to the invention is shown in FIGS. 1 and 2. The anchor channel has a channel element 1 having a slot 14 that runs along the channel element 1 and that is flanked by two legs 15 and 16 of the channel element 1 that run along the channel element 1, so that the channel element 1 has a C-shaped cross section. The legs 15, 16 are configured with undercuts, so that a T-head bolt 7 inserted through the slot 14 into the interior of the channel element 1 can be turned in order to positively secure the bolt to the legs 15 and 16.

(6) On the bed of the channel, in other words, on the side of the channel element 1 that is opposite from the slot 14, there are numerous nail holes 18 in the channel element 1, and they serve to secure the anchor channel to the formwork before the concrete part 100 is poured.

(7) Moreover, a plurality of identical fastening points 20, 20′, 20″—three of them in the embodiment shown—are provided on the bed of the channel element 1. Particularly as is shown in FIG. 2, at the fastening points 20, each channel element 1 has an opening 23 into which a rivet 26 is placed. The rivets 26, in turn, each have a drilled hole 22 with an internal thread 24. The internal threads 24 define the fastening points 20. In this manner, a plurality of identical internal threads 24—in other words, especially threads having the same dimensions—are present on the channel element 1, and these threads form a plurality of identical fastening points 20.

(8) As is shown in FIG. 1, an identical anchor element 30, 30′ is attached to each fastening point 20 and 20′, especially by screwing the anchor elements 30, 30′ into the corresponding internal thread 24. The identical anchor elements 30, 30′ all have the same shape and the same dimensions. They are configured as cylindrical stud anchors and are each provided with a thickened section 31 at their end facing away from the channel element.

(9) An additional element 40 whose shape differs from that of the identical anchor elements 30, 30′ is attached to the third fastening point 20″. In the embodiment shown, the additional element 40 is configured as a rebar. Therefore, instead of an anchor element 30, an additional element 40 is attached to at least one of the identical fastening points 20, said additional element 40 differing in shape from the identical anchor elements 30, 30′, all of which have the same shape.

(10) As is indicated in FIG. 2, the anchor channel can be cast into a concrete part 100 according to the invention, whereby then the channel element 1 as well as the anchor element 30 are surrounded by concrete.

(11) FIG. 3 shows alternative embodiment variants of the additional element 40 which, aside from the identical anchor elements 30, are also attached to at least one of the fastening points 20. Therefore, the additional element 40′ can be configured as a profiled rebar, for example, in order to withstand additional loads such as, for instance, explosions. The additional element 40″ can also be configured as a specially shaped anchor rod, for instance, with a wider anchor head, in order to increase the load-bearing capacity. The additional element 40′″ can also be configured as a non-load-bearing, especially tab-like, connecting part to be positioned in the formwork or else to be welded onto the rebar. Particularly in this case, the surface characteristics of the additional element 40′″ and of the anchor element 30 can differ: whereas the anchor element 30 can have, for instance, a corrosion-protection coating, this corrosion-protection coating can be absent in the non-load-bearing additional element 40′″, for example, in order to ensure better welding properties.

(12) The additional element 40′″ can also be a grounding strip, for instance, in order to dissipate short-circuit currents. However, the additional element 40′″″ can also be an adapter piece by means of which vertical, horizontal, angled or slanted anchor elements 47 in different versions (e.g. rebars, head bolts, threaded rods, screws) can be affixed to the channel element 1 in a rigid or articulated manner. The additional element 40′″″ configured as an adapter piece is preferably shaped like a screw, a threaded pin, a cylinder, a structural steel part, a lug or the like. The anchor element 47 can be fastened to the adapter piece by means of various joining techniques, but preferably by means of screwing, gluing or welding. For purposes of attaining corrosion protection, the adapter piece can be protected at its connecting point to the channel element 1 or else it can be made of rust-proof material (stainless steel, plastic).

(13) The additional element can also be employed to position the anchor element in the formwork. For this purpose, the additional element can have a threaded rod.
