Floor
The term floor is used to describe the component in a building which rests as a walkable surface with different floor coverings, depending on the technical and aesthetic requirements, on a statically supporting layer or a horizontal component such as the floor slab or storey ceiling.
In construction, the floor structure is 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, essentially depending on the construction and the use of the building. Floor structures in timber construction, for example, differ fundamentally from those in solid construction or reinforced concrete construction. In modern buildings, building physics with requirements for sound insulation (structure-borne sound and airborne sound) and thermal insulation play a particularly important role.
- Today, superstructures are widespread in which a screed is located on a reinforced concrete slab. The floor covering lies on the screed.
- A hollow floor is a type of system floor that is supported on special substructures to create a cavity between the load-bearing layer and the raw ceiling to accommodate installations. See also: raised floor.
