Spacer for upper reinforcement in reinforced concrete ceilings

Spacers for upper reinforcement in reinforced concrete ceilings are available in different Executions known. In particular, they are known as stools made of wire, or as large-shaped frames, also made of wire.

does. In addition, lattice girder-like spacers are known which Veilegt at intervals, thus large-scale supports of the upper ones

[Form reinforcement. These known spacings have different ones

Disadvantage. In the case of stool-like constructions, the load-bearing capacity is low and the manual effort very high. For large spacers the load capacity is generally limited. The innovation avoids these disadvantages- The innovation relates to spacers for the upper reinforcement in reinforced concrete ceilings and has the output that to keep the upper reinforcement at the prescribed height and to secure it against being pressed down during laying and concreting. The feet of spacing ^ TS give the measure of the distance between the top and bottom Occupation The inner foot of this holder also has the task of to stabilize the holder. The feet of this spacer can j

\ be protected against corrosion by a plastic coating. j

In follow rden the innovation is based merely an exemplary embodiment \ game drawing representing explained. It shows: ;

Spacer for upper reinforcement in reinforced concrete ceilings.

The spacer shown in plan view in FIG. 1 consists from Kundstäben 1 and 2. The rod 1 is straight and has feet 3 and 4 bent downwards. The foot 4 is around the dimension of the rod 2 in Point 5 shorter. The rod 2 is bent in a V-shape at any angle and also has feet 3 bent downwards at the ends. At point 5, bars 1 and 2 are connected to one another, e.g. by resistance spot welding tied together.

The spacer shown in Figure 2 shows in side view next to the welded joint 5, the feet 3 and 4 bent downwards. The length of the feet corresponds to the height de? Spacer. The feet 3 are outside and the foot 4 in the middle of the spacer.

In Figure 3, the spacer is shown in perspective. The feet 3 and 4 can be provided with corrosion protection at the lower ends to avoid rusting later.
