Abstract
An athletic floor assembled on a foundation having a capacity to absorb vibration, eliminate dead spots, and remain stable and resistant to the damaging effects of moisture which comprises discrete sections of reproducible subflooring constructions which are separated from each other so there are gaps between every section which prevents the ripple effect transmission of vibration forces which combines a wood nailing bed underlayment engaged inside the open face of a c-channel support system in which such engaged components are held in fixed elevation over the foundation and supported on strips of resilient material, and further comprising anchoring clips having a vertical riser member and engagement tabs at a top and which are engaged to the channels inside deflexure slot aperture cut in the channels and engaged to the foundation by fastening tab means at the bottom end and adapted to permit the entire floor construction to experience slidable vertical deflexure movement as limited by the limits of the deflexure riser element.
