Abstract

The invention relates to a timber-concrete composite slab with a planar timber element, which allows for spans to be achieved with little dependence on the relative self-weight of the slab. The slab layer structure comprises a timber layer, an insulation layer, and a concrete layer (4). In one embodiment, the layer structure is interrupted by at least one beam (8) that extends through at least the concrete layer (4) and the insulation layer and reaches downwards at least to the timber layer. This internal beam (8) can also be designed as a cantilevered element projecting from the composite layers. In another embodiment, the slab incorporates two insulation materials of different densities in its insulation layer for enhanced sound insulation, with the denser insulation material resting directly on the timber layer, thus acting as vibration damping. In a further embodiment, the timber panels forming the planar timber element of the timber-concrete composite slab are tensioned against each other to transmit tensile forces. According to the invention, the efficiency of manufacturing timber-concrete composite slabs with large spans can be significantly increased.
