Apartment Buildings in Hybrid Construction
Manufacturer: Dennert Baustoffwelt GmbH & Co. KG
Product: Prefabricated concrete ceilings
Product category: Constructions
A total of 3,000 m2 of ceilings were installed in the three five- to seven-storey apartment buildings. The individual ceiling elements are up to 7.4 m long and 2.24 m wide. The prefabricated walls of the building are made of wood. One floor per building was erected each week. The concrete ceiling elements are prefabricated in the factory as individual pieces and delivered to the construction site as dry components. The ceiling thicknesses vary from 20 to 24 cm and reach fire resistance class F90. After installation, the ceilings are immediately loadable and walkable. According to the manufacturer, the DX ceilings weigh less than wooden versions equipped with sound insulation and fire protection of comparable quality. Cavities are integrated into the ceilings, inside which cable ducts can be accommodated. A special locking system creates a stable and friction-locked composite structure.
