Description

[0040] In the following, the invention of the device will be explained in more detail with reference to drawings. In the drawings:

[0041] FIG. 1 shows a spacer carrier plate having a guide channel for a fastening means and a top-side receiving depression for a reinforcing rod;

[0042] FIG. 2 shows a spacer carrier plate with two hook-shaped adapter elements on the top side of the spacer carrier plate facing away from the spacer;

[0043] FIG. 3 shows a design with two top-side eyelets;

[0044] FIG. 4 shows another design with four receiving hooks arranged at the periphery;

[0045] FIG. 5 shows a design with channel-like guides placed thereon;

[0046] FIG. 6 shows a design with a top-side planar notch for receiving a fastening means;

[0047] FIG. 7 shows a design with hook-shaped fastening elements arranged at the four corners of the carrier plate;

[0048] FIG. 8 shows a design with a receptacle arranged in the manner of a rail for fastening means on the spacer plate, and

[0049] FIG. 9 shows an arrangement of a spacer 20 on reinforcing bars 21 by means of an approximately V-shaped fastening means 22.

[0050] FIG. 1 shows a design of the spacer carrier plate 1, in which a receiving channel 2 as an engagement receptacle is embedded in the spacer carrier plate 1. In addition, the spacer carrier plate has a depression 3 in its top side 4, in which a reinforcing bar, not shown, can engage. In this way, better supporting of the spacer 20 on the reinforcing bar 21 is possible.

[0051] On the underside it can be seen that, in this design, only one fastening extension 5 is provided for insertion into a concrete spacer, for example. That is to say, this element has a centrally arranged fastening extension 5, which, by way of a widened portion at its end, produces a step 6 running around it, which ensures a fixed seat in the cured concrete spacer.

[0052] In principle, all the designs together have a carrier plate 16, which has the fastening extensions 5 on its lower, first surface 17 and the engagement receptacles and/or engagement surfaces in a different design on its upper, second surface 4.

[0053] The first surface 17 thus faces the spacer and, in the installation situation, lies flat on the surface of the spacer 20 or is at least partially recessed therein. In the installation situation, the second surface 4 of the carrier plate 16 forms the free top side of the spacer and is therefore provided with engagement receptacles and/or engagement surfaces for the fastening means, for example wires, with which the spacer 20 can then be fixed to the reinforcement by means of the spacer carrier plate 1.

[0054] FIG. 2, in contrast to FIG. 1, has, on the underside of the first surface 4, a plurality of mandrel-like fastening extensions 5 with steps 6, wherein two hook-shaped engagement extensions 7 running diagonally into two corners are now arranged on the top side 4. Said engagement extensions are used, for example, for receiving fastening wires 23, which can be guided via the open hook ends 8.

[0055] The choice of wire 23, whether eyelet wire or straight wire or black wire or VA wire, can thus be freely se-lected by the end user during installation. The length of the wire is also freely selectable for all shapes.

[0056] FIG. 3 shows a similar but deviating design, which now instead of the open hook-shaped engagement extensions 7 has channel-like eyelets 9 on the top-side second surface 4 of the spacer carrier plate 1. Here, too, the guiding of fastening wires through these eyelets 9 is provided in particular.

[0057] FIG. 4, in turn, shows four hook-shaped engagement extensions 7, which are arranged in pairs at the periphery on the top-side second surface 4 of the spacer carrier plate 1 with their open hook ends 8 facing outward. In this way, for example, criss-crossed wiring to the center of the spacer carrier plate 1 can be carried out and also it is possible to arrange a plurality of fastening wires, as a result of which secure fastening to the reinforcement is made possible since the open hook ends 8 oriented facing away from the center of the spacer carrier plate 1 reliably prevent the fastening wires 23 from sliding during the fixing.

[0058] FIG. 5 shows two engagement channels 10 aligned with respect to each other in pairs on the top-side second surface 4 of the spacer carrier plate 1. Various fastening elements can be inserted into these fastening channels 10 or eyelets. For example, spring steel clamps 22 can also snap laterally here into these fastening channels 10 and can be guided therein in an articulated manner. Alternatively, the use of fastening wires 23 is of course also an option here.

[0059] This spring steel clamp 22 can be pushed with the lower end into the two tunnels. A slightly snake-shaped bend secures the clamp when inserted in the gap between the two tunnels from slipping out. The spring steel clamp 11 can be adapted here on the construction site depending on the size of the rod diameter. It is therefore not necessary to supply an extra type of spacer for every situation.

[0060] FIG. 6 shows a different design, in which it is provided that a planar receiving notch 11 forms a guide rail 12, which is U-shaped in profile, on the top-side second surface 4 of the spacer carrier plate 1. It can be seen that, in this design, six underside fastening extensions 5 on the underside of the spacer carrier plate 1 can be cast into the spacer. This ensures a stable fastening of the spacer carrier plate 1, for example in cast concrete. The top-side approximately U-shaped planar receiving notch 11 as an engagement body for a fastening means also has a top-side tooth profile 13, which serves to bring about secure support on a reinforcing bar.

[0061] FIG. 7 shows an alternative design, which is similar to the design according to FIG. 4. Here, too, open hook ends 8 are provided, which now however are not arranged parallel in pairs but rather at all four corners of the spacer carrier plate 1 which in this case is square. This also ensures that criss-crossed bracings with wires provide secure supporting on a reinforcing bar. Here, too, central tooth profiles 13 are provided centrally in order to avoid twisting of the spacer on the reinforcing bar.

[0062] Finally, FIG. 8 shows a design with a receiving rail 14, which is placed on the top-side second surface 4 of the spacer carrier plate 1. Access to said guide rail takes place via a diagonally running guide channel 15, into which, for example, a fastening spring steel sheet can also be inserted.

[0063] This clamp is intended to be fastened to the reinforcement in conjunction with a metal sheet or spring steel sheet. This sheet is intended to be pre-bent and the spacer can therefore be used on a very wide range of rod diameters. Furthermore, it is possible also to form this V-shaped fastening element from plastic.

[0064] In addition, this fastening means can be fastened with electric binding machines. There is the possibility of forming this V-shaped fastening means in such a way that the spacer with the clip can also be retrospectively fastened to the V-shaped fastening means.

[0065] This means that first the V-shaped fastening means 22 is fastened to the reinforcement and then the spacer is tightly clipped in place. Or first the V-shaped fastening means 22 is clipped into the clip and then tightly clipped onto the reinforcement.

[0066] FIG. 9 shows, by way of example, such an installation situation of a spacer 20, into which the spacer carrier plate 1 according to the invention is inserted. It can be seen here that the fastening extensions 5 protrude into the spacer 20, wherein the carrier plate 16 rests flat on the top side of the spacer 20.

[0067] In this design, a fastening via the spacer carrier plate 1 is shown by means of a guide rail 12. In this guide rail 12, there is a corresponding receiving notch 11, in which an approximately V-shaped fastening means 22 engages. The latter can be made of spring steel, for example.

[0068] In a lower horizontally running section, this V-shaped fastening means 22 engages in the notch 11 and thus secures the spacer 20 to a reinforcing rod 21, shown in cross section. The actual fastening takes place via a reinforcing rod 21 which runs transversely with respect thereto and to which the V-shaped fastening means 22 is fastened by means of fastening wires 23.

[0069] It becomes clear from this that a V-shaped fastening means 22 which is detached from the spacer 20 is present, said fastening means engaging on the spacer carrier plate 1, which is fixedly inserted into the spacer 20, wherein this is merely a V-shaped fastening means by way of example, since other fastening means are also suitable for being able to engage in the notch 11 on the spacer carrier plate 1. This illustrates the flexibility in the arrangement of the spacers 20, provided that they have the spacer carrier plate 1 according to the invention.
