Spacers are supports that allow the desired spacing between the reinforcement layers to be maintained.
There are various of spacers, such as snake and SBA.
The support baskets are dimensioned in such a way as to normally withstand the load when mounting the reinforcement and in the concrete when the lateral spacing according to the table below is respected.
For problematic areas (local high demands or little self-stiffness of the upper reinforcement layer) a load-sharing flooring is recommended. Alternatively, it is also necessary to reduce the spacing.
For higher demands, we recommend that you use a support basket with the appropriate wire strength.
| Side spacing | It means |
| with weak reinforcement: 0,5 – 0,6 m | 1,0 ks/m2 upper reinforcement |
| with middle einforcement: 0,6 – 0,7 m | 0,8 ks/m2 upper reinforcement |
| with strong reinforcement: 0,7 – 0,8 m | 0,7 ks/m2 upper reinforcement |
| Diameter of supported rods | Distance when laying in a row |
| d < 6,5 mm | 50 cm |
| 6,5 mm > d < 12 mm | 70 cm |
| d > 12 mm | 70 cm* |
* if a greater set-up spacing is chosen, it must be proven by calculation
