New construction indoor swimming pool, Frutigen

The project
The new swimming pool is intended to expand the offer and the possibilities of use and to increase the attractiveness. The technical facilities will also be renewed and adapted to today's standards. The new wooden building will be built in line with the existing restaurant and the checkroom wing. Thanks to the large window front, the beautiful view can also be enjoyed while swimming. The main supporting elements of the roof consist of approx. 20 m long glulam beams. To make the view of the mountains even more inviting, the single-span girders were tapered towards the window front. The trusses are supported on pendulum columns and stabilized by the roof slab and walls. Tabs hidden in the wall structure provide the fork bearing. In order not to interfere with the view, the trusses at the glass front are supported on filigree steel columns. The stabilization of the transition from the concrete column to the glulam beam is solved with glued-in threaded rods (GSA system). This invisible fork bearing also serves as transverse pressure reinforcement.

The construction method
The secondary supporting structure consists of box girder elements that were prefabricated and fixed to the glulam beams. The building is braced on the one hand by the existing concrete wall of the checkroom building and on the other hand by bracing timber walls. In order to transfer the large forces, a brace frame is integrated in one wall slab. The roof is braced by OSB panels, which also stabilize the main structure. The walls consist of a prefabricated frame construction.
