Kurtheater Baden

Baden, Switzerland

Project description
As part of the renovation work at the Kurtheater Baden, several reinforced concrete beams had to be retrofitted with pre-stressed shear reinforcements. The principle of the embedded re-bar was chosen for this purpose. Previously, the side surfaces and the underside were hydromechanically removed. After pre-drilling the plates, the U-shaped stirrups made of memory steel could be positioned. The holes in the plate were then filled with grout, and the remaining side surfaces were covered with a levelling mortar after installing a formwork. The final activation (prestressing) of the stirrups was carried out by resistive heating.
