The floor is the component in a building that rests as a walkable area with different floor coverings depending on the technical and aesthetic requirements on a statically load-bearing layer or a horizontal component such as the floor slab or floor .
In the building industry, the term “ floor structure ” refers to the totality of all layers of the floor. Modern floors usually consist of several layers that perform different functions. The floor can be constructed in different ways, depending mainly on the construction and the use of the building. Floor structures in timber construction differ fundamentally from those in solid construction or reinforced concrete construction , for example . In modern buildings, building physics, with requirements for sound insulation ( structure-borne noise and airborne sound ) and thermal insulation, play a major role.
- Constructions in which a screed is on a reinforced concrete slab are widespread today . The floor covering lies on the screed .
- A cavity floor is a system floor construction that is stored on special substructures in order to create a cavity between the base layer and the raw ceiling to accommodate installations. See also: double floor .
