type of slab in wood-concrete composite construction, in which a reinforced in-situ concrete layer (from 6 cm thick) is shear-resistant to a layer of wooden beams underneath. Both material components act statically as a single component, with the timber cross-sections absorbing the tensile stresses and the concrete bearing the compressive load. The composite is created using suitable composite materials, usually approved by the building authorities, which can usually also be installed by means of a wooden formwork resting on the beams.
This type of ceiling is mainly used in the renovation of the ceilings of old buildings, whereby existing intact wooden components are retained and the ceiling meets modern requirements thanks to the additional layer of concrete. This beam ceiling is also used in new buildings, for example in multi-storey residential buildings or multi-storey timber construction. It can be produced on site, but can also be delivered to the construction site in the form of precast elements in full assembly. The reinforced concrete layer has already been installed in these elements. On site, only the joint grouting has to be carried out to connect the elements with each other.
