Hybrid constructions: Deltabeam optimises material combinations

Hybrid construction methods have been an important trend in the construction industry for some time now. In the public perception, however, concrete as a building material is often criticised and steel is also questioned from an ecological point of view. Nevertheless, concrete and steel are essential components of hybrid constructions and their use can hardly be replaced due to their excellent material properties.
Deltabeam is an excellent solution for slender constructions such as timber or timber-concrete composite ceilings. Conventional timber constructions usually reach the limits of what is feasible with large spans. By using Deltabeam, larger column spacings are possible with up to 30 per cent less slab thickness. The composite effect of concrete and steel with Deltabeam enables large spans that create open spaces with a minimum number of columns. In addition, fire protection is integrated when Deltabeam is used, so there is no need for time-consuming fire protection coating on the construction site or during building operation.
In the latest fire tests with the timber hybrid construction system from Cree Deutschland GmbH and the Deltabeam composite beam from Peikko, a fire resistance class of REI120 was achieved. This means a fire resistance duration of 120 minutes in terms of load-bearing capacity, room closure and thermal insulation.
More information on Deltabeam in combination with timber hybrid buildings and the results of the fire tests will be available to interested parties at the Bau trade fair in Munich from 13 to 17 January 2025 at the Peikko stand in Hall A2, Stand 408.
