A covering plate (5), for flooring in conveyances such as a railway car, is provided with a securing track (11) for securing seats, etc. The covering plate (5) is formed by a sandwich structure having a central core (24) arranged between an outer plate (25), which extends across the entire size of the covering plate, and second outer plates (26). The securing track (11) is formed in a profile (27) embedded in the sandwich structure so that a securing track (11) extends at a right angle to lateral edges (14) of the covering plate (5). As either end of the profile is provided with tracks (29) for receiving tight-fitting pins (30), a floor structure can be mounted easily and rapidly.
