Re-Fer

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.
