Spacers

Spacer pads are supports that maintain the required distance between layers of reinforcement.
There are various types of spacer pads, such as the Had and SBA types.
Support cages are designed to withstand the loads during reinforcement installation and concrete placement under normal conditions, provided that the lateral clearances specified in the table below are observed.
For problematic areas (locally high demands or low inherent stiffness of the top reinforcement layer), a slab floor that distributes the load is recommended. Alternatively, it may also be necessary to reduce the spacing.
For higher demands, support cages with the appropriate wire strength must be used.
Determining the dimensions of the supports
| Boční odstup | To odpovídá |
| při slabé výztuži: 0,5 – 0,6 m | 1,0 ks/m2 vrchní výztuže |
| při střední výztuži: 0,6 – 0,7 m | 0,8 ks/m2 vrchní výztuže |
| při silné výztuži: 0,7 – 0,8 m | 0,7 ks/m2 vrchní výztuže |
| Průměr podepíraných prutů | Odstup při pokládce v řadě |
| d < 6,5 mm | 50 cm |
| 6,5 mm > d < 12 mm | 70 cm |
| d > 12 mm | 70 cm* |
* pokud bude zvolen větší odstup pokládky, je třeba jej prokázat výpočtem
