An innovative structure was built in Salzburg in 2019. The tower building of the Salzburg Regional Health Insurance Fund is one of the first timber hybrid high-rise building in Austria. The supporting structure was planned as a skeleton construction, with glulam columns and beams and ceilings in wood-concrete composite construction. The beams of the ceilings were screwed "dry" to the prefabricated reinforced concrete slabs. These are used for cooling and heating by means of component activation. The total ceiling area is approx. 2,000 m².
The tower is approx. 18.0 m long, 19.5 m wide and extends over a height of approx. 33.2 m. The building consists of nine full stories and has a full basement. In addition to the basement and first floor, the central access corridor as well as the staircases and elevator shaft are made of reinforced concrete. The building is braced by the massive staircases. The ceilings above OG 1 to OG 8 are of wood-concrete composite construction (WCC) and the exterior columns adjacent to the WCC ceilings are made of glulam. The design of the roof structure corresponds to the ceilings of the subjacent floors.
The hybrid construction method and the resulting building height render the building special. In addition, the chosen design in combination with the modular construction enables a fast constructiontime of the timber structure of only approx. 48 h per floor.
