Punching shear reinforcement of a hotel, Scuol
Description
During the renovation of a hotel building in Scuol, the existing slab had to be strengthened in the area of new supports. A clever combination of existing internal reinforcement, new ancoSAN punching shear dowels and our memory®-steel re-bar 16 was used.
The advantage: the high ductility of memory®-steel allows optimum utilisation of all load-bearing components – without the risk of local ‘ceiling embrittlement’. The active prestressing brings the reinforcement directly to a stress level comparable to the existing reinforcement. Additional deformations, as would be necessary with conventional systems, are not required – cracking is thus effectively reduced.
To protect the internal reinforcement and the punching shear dowels, the re-bars were heated using electricity to avoid damaging the existing internal reinforcement.
A successful example of the combination of innovation and existing building.
