Re-Fer

Description
In an apartment building, it turned out that a reinforced concrete balcony was sagging excessively and had structural deficiencies. As the balcony is directly connected to the internal concrete ceiling, negative bending reinforcement was possible to ensure the load-bearing capacity.

To further correct the sagging of the balcony, pre-tensioned re-bars were used. The team from Iten Spezialhochbau first relieved the balcony by lifting it with a hydraulic press. The re-bars were inserted in grooves, anchored, prestressed, and grouted to hold the balcony in the desired position, even after the support had been removed.

Thanks to this reinforcement method, the bending load-carrying capacity of the balcony was improved and the deflection reduced by 20 mm.
