Various spacers are known, but all of these known spacers have disadvantages. For example, known spacers, which are used in particular for ceiling reinforcement, have to be connected to the reinforcement mats by so-called "knotting", which is extremely cumbersome and time-consuming. Other known spacers that or the like in the manner of a trestle. are designed, have the disadvantage of an unstable stand, so that they can easily fall over when they are loaded v / ground, or there are again additional measures to establish the connection with the reinforcement mat, quite apart from the fact that with all these known arrangements special spacers are assigned to each of the two types. All of this makes attaching and installing the reinforcement relatively cumbersome. In particular for vertical reinforcement there are spacers which consist of a sheet metal strip "which has brackets that can be bent around the mats like a flap and which also has support feet. These known arrangements have the disadvantage that they can be easily bent and that in the case of that the "two mats are offset from one another in the plane of the mat so that the rods and wires corresponding to one another are not exactly opposite one another and cannot maintain the correct distance due to the inclined position. All known arrangements therefore have the disadvantage that the attachment is relatively cumbersome

713291223.11.72

and time consuming and their scope is relatively narrow and is limited.

In contrast, the present invention has the task asked to find a remedy here and to create an arrangement of the type in question here simple oeise "and above all wirelessly or without tying up can be used and connected to the reinforcement mesh and, moreover, practically in all of them without any change Use cases can be used.

For the above purpose it is provided according to the invention, that at least one of the two brackets is designed as a clamping eyelet open on one side and the two Brackets are connected by at least one spacer in the form of a wire or rod made of iron, the is so strong that it can absorb a load from one of the reinforcement meshes without deformation. Here the arrangement is expediently made so that dis the open end of the Kleümöse with its closed end connecting imaginary center line in the plane of the assigned reinforcement mesh uder in a parallel to it Level is included, preferably with two clamping lugs Contains wire or rod elements, between each of which a wire or rod of the reinforcement mat can be clamped. Eg can E.g. the new spacer can be made of a single rod or wire that has a spacing

713291223.11.72

piece forming middle, rectilinear part, the length of which corresponds to the intended distance between the two reinforcement meshes, and two at the two ends in the middle part has elem eyelets in the same plane, roughly in V-shape or U-shape are bent, the free ends of the outer legs of the U or V each bent outwards are.

The arrangement according to the invention has the advantage that the connection between the spacer is now established and the individual reinforcement bars without drainage, i.e. without the so-called "anrödeln" can be made what has the advantage that much less time and work has to be expended. Another benefit of the new Arrangement is that the field of application is much larger than the known arrangements comparable Kind is by having them practically without any change for both vertical and horizontal reinforcement in the production of walls or ceilings of any type and can also be used in the production of recesses or recesses in the wall. One can thus take place now the previously required different types of spacers manage with a single Haiterungstype, which is what it is makes it possible to streamline and simplify production and warehousing to the maximum.

These eyelets are at one end ( at 7j 7a) closed and open at the other end, with the two clamping eyelets open on the same side. 12a, which are connected to one another at one end of the clamping eyelet and extend diverging from this point to the other open end 8 or 8a The free ends 9-10 of the outer legs " ⁵ I are each bent towards the outside, whereby they are arranged coaxially or approximately coaxially to one another and with the middle part 2 in the same way The spacer between the two clamping eyelets, which is formed by the middle section 2, consists of a straight wire or rod made of iron, which is so strong that it is subject to a load from one of the Can accommodate reinforcement meshes without deformation. When used in conjunction with vertical reinforcement, for which this type of application is generally intended, there is hardly any load on the spacer "

The arrangement according to FIG. 3 is a spacer, which consists of a straight rod or wire 14 "extending over its entire length, which in the Area of its axial ends each one on it by welding attached clamping eyelet 15 "or 16 carries, the from an approximately U-shaped bent piece, e.g. a so-called staple or the like. consists and on a level with the other clamping eyelet and the rod or wire is included, such as Pig. 3 clearly shows. The clamping eyes are in two places at 15a, 15b and 16a, 16b Your rod or wire 14 connected, their legs run again slightly converging towards the free end, so that the wires or bars 17 of the reinforcement mat can be clamped between the legs and hold in place. Even Mer is, liie in the embodiment of Fig. 1, which open end 15c or 16a of the Hemmöse with its closed End 15d or 16d connecting center line in the plane of the associated 3ewea approximately mat or on one contain a plane parallel to this (cf. also FIG. 2). The clamping eyelets can of course be attached to the middle section also be connected at a single point.

In the middle part 18 of the rod or wire is a distance from the inner one Section of loading wire piece 19c or 20c attached, z, B. welded on. This braht piece 19c or 20c forms with the inner section 19a or 20a in turn a closed section at one end and a closed section at the other end open clamp eyelets, the legs of which point towards the free ends converge easily. The two pieces of wire and the inner sections are here on the same side of the central part 18 directed. This embodiment 3, like the variant according to FIG. 3, is primarily for use in conjunction with vertical reinforcement - i.e. intended for horizontal arrangement of the spacer.
