Abstract (en)
[origin: EP0339537A2] A hollow flooring for covering a supporting floor, which has a covering layer, a bearing surface, supports and at least one inner space extending between the supports is formed, at least regionally, from individual adjoining shuttering elements. Arranged in the region of at least one lateral edge of the shuttering element is a seal which impinges on another shuttering element. The adjoining shuttering elements form, in the region of their upper boundaries in the vertical direction, the bearing surface. The covering layer extends over all shuttering elements arranged in the region of the hollow flooring. The seal is, at least regionally, in the form of a labyrinth seal. At least one bead is arranged in the region of the labyrinth seal. The beads are substantially trapezoidal in shape and have, in the region of their bearing surface, their greatest extent in the horizontal direction. <IMAGE>
