摘要

The floor surface (10) has longitudinal (12) and transverse (16) supports for at least one floorboard (30,32). At least one longitudinal support has at least one suspension groove and at least one support projection assigned to the suspension groove. At least one transverse support is formed as a suspension support, which has a connecting tongue on at least one end face and is placed on the support projection to engage the suspension groove.
