Spacers for rebar

The innovation relates to a spacer for rebar, in particular for reinforcing iron braided into mats, as used in reinforced concrete construction. When creating ceilings and walls, especially in reinforced concrete structures, reinforcing iron must be inserted into the concrete, which in most cases are braided together to form relatively large mats. Bend these large mat surfaces so that it is evenly spaced from the To ensure that the formwork is set in concrete, that it is provided with spacers «.

The known spacers used are as K'lemmringe formed and made of a plastic, for example PVC or the like made. The area of these clamping rings

is provided with perforations to allow the Eeton to pass through otherwise at the contact points of the clamping rings No concrete connection is created because these are made of plastic .Wings practically a foreign body within the blankets respectively Walls are.

The known clamping rings also form in the processing of Cichtbeton Flt-cKen, because they consist of a non-concrete material, ! - but they have the disadvantage that they are in the shade the concrete can be pressed down by the reinforcing bars. They do not offer fire protection and they are also different Dur '.: Linesser of the reinforcing iron respectively corresponding Models necessary, which means a not inconsiderable inventory · .- r for the 11 c h is.

The innovation is based on the task of creating a ring-shaped To create spacers that are intimately connected with Guaranteed the ketone, does not fall off the reinforcing iron can and also in its design for the various rebars can be used, se that with the known Plastic clamping rings existing disadvantages are avoided and the storage is considerably reduced, This object is achieved according to the fire in that the Äbötanüshalter tez «. -rings made of two hinged together and, in their band position, they sound like king sections consist of iieton or a similar material. This training of the spacer in j.eton is an intimate Connection of the concrete to be poured with the spacer

example. Bs show:

Fig. 1 is a plan view of a reinforcing iron mat with exposed Spacers respectively. -ring, FIG. 2 shows a detail from FIG. 1, FIG. 3 shows a side view of FIG. 2, partially in section, Fig. 4 BEZW a spacer. -ring when open and

5 shows the spacer ring in the closed state. FIG. 1 illustrates a mat 1, which is braided from reinforcing iron 2, 3 and, for example, ^{1 is used} to create a decice. On the rebar 'q are spacers respectively. -rings 4 placed, which hold the mat 1 from the formwork 5 at a distance that BEZW by the wall thickness of the spacers. rings is set.

The spacers respectively. rings 4 are available as ring sections 6 and manufactured, in which a wire 8 is embedded in such a way that a joint 9 is formed on the periphery of the spacer ring 4, the Ends lo, ll of the wire 8 protrude opposite the joint 9, so that by twisting them with one another, the li'.ing sections 6 and 7 hold together (Fig. 5).

As can be seen from FIG. 2, the distance between the reinforcing iron mat 1 is determined by the wall thickness of the spacer ring 4, so that the Starlcr? the reinforcing iron 2, 3 has no effect on the distance between the mat 1 and the formwork 5. The figure 4 shows how the spacer rings 4 respectively on the reinforcing iron 2. 3 with open Hing sections similar to. '. 7 are put on.
