Renovation indoor swimming pool fairy tale hotel, Braunwald

The project
The fairy-tale Bellevue Hotel in Braunwald has an attached indoor swimming pool. Its roof structure was realized from five pairs of twin girders in glulam. The single-span girders span around 10 meters. Due to an overload, two of these girders suffered a bending failure. Along the edge of the pool, the room height had to be maintained, and sufficient space was available above the pool.

The construction method
As part of the refurbishment, both the broken girders and four of the remaining girders (which were too small) were strengthened. The focus was on aesthetics. The solution was to use a steel substructure. Due to the aggressive swimming pool climate, high-quality, authentic chrome steel was used. All tie rods, connecting parts and fasteners are also made of this material. Ribbed CORRFIX tie rods were glued in place to introduce the tensile forces into the glulam beams.
