The present invention will be explained in more detail hereinafter with reference to the figures, in which FIG. 1 is a schematic side elevation of a special embodiment of the present sports floor and FIG. 2 is a top plan view of the honeycomb structure as used in FIG. 1.
FIG. 1 shows a schematic side elevation of a special embodiment of the present sports floor 1, which sports floor 1 is suitable for practising a ball sport thereon, for example soccer or hockey. Earth is removed from a piece of land to a particular level below the final surface level, which level is in fact determined by the frost penetration depth. If desired, drainpipes may be provided. Following that, the support base 6 is filled up with a stable material, for example sand, crushed stones or the like, and in a specific embodiment earth from the previously stripped piece of land may be used. Subsequently, a honeycomb structure 4 is placed on the support base 6, which honeycomb structure 4 consists of a series of substantially identical cells arranged in rows, which cells have lateral cell walls adjoining each other according to an annular configuration so as to form cell openings 8. To obtain a stable construction, the cell openings 8 are filled with a filling material 7, for example sand. Following that, a substrate 2 is placed on the honeycomb structure 4, which substrate 2 is a substrate provided with synthetic fibres in the embodiment that is shown in FIG. 1, which synthetic fibres extend substantially transversely to the substrate 2. To prevent movement of the substrate 2 with respect to the honeycomb structure 4 and the support base 6, it is desirable in a specific embodiment to provide an intermediate layer 3, which intermediate layer 3 may be provided with means for preventing movement of the substrate 2 with respect to the honeycomb structure 4 and with respect to the support base 6, which means are present both on the side of the intermediate layer adjacent to the honeycomb structure 4 and on the side of the intermediate layer adjacent to the support base 6. In a specific embodiment it is also possible, on the other hand, to provide the substrate 2 at the lower side thereof with a studded structure, for example, which studded structure makes contact with the honeycomb structure 4, thus preventing movement of the substrate 2 with respect to the honeycomb structure 4 so that intermediate layer 3 may be omitted. In a specific embodiment it is furthermore desirable to provide an additional layer 5 between the honeycomb structure 4 and the support base 6.
FIG. 2 is a top plan view of the honeycomb structure 4 that is shown in FIG. 1, which honeycomb structure 4 consists of a series of substantially identical cells arranged in rows, which cells are provided with cell openings 8, in which cell openings 8 a filling material 7 is present.
