Sprung floor

As sprung floors coverings are used for sports halls designated giving way under stress.

A distinction is made between area-elastic sprung floors, which give way in a large area when subjected to stress, and point-elastic sports floors, in which the so-called deformation trough is hardly larger than the burdening object. In addition, DIN 18032 distinguishes between combined elastic and mixed elastic sports floors, which combine the advantages of area and point elastic floors in their properties.

Area-elastic vibrating floors usually consist of double-laid wooden strips as vibrating beams, a sub-floor with a board spacing of 50 to 70 mm and a load distribution plate screwed onto it. Wood or plastic floor coverings can then be applied as a wear layer . If a parquet is applied as a wear layer , it is called a vibration parquet , as is particularly common in dance schools and ballet halls.

Point-elastic sprung floors are more simply constructed; They consist of a layer of foam that supports an elastic plastic floor covering.
