Definitions

  • the invention relates to a floor surface attachment, which develops a filter effect for flowing fluids and is formed from porous material, such as concrete or plastic, and has at least two superimposed layers in the flow direction from the inlet top to the outlet underside, of which the top layer on the inlet side is much thinner than each of the layers below is and the free flow cross-section of the inlet-side layer formed by the pores of the porous material is smaller than the free flow cross-sections of each of the layers below, the dimensions of the free flow cross-sections increasing in the layers successive in the flow direction.
  • porous material such as concrete or plastic
  • Such a floor mounting is known from Van Gelder: “Wegenbouwers Beperken Verkeerslawaii”, de Herbstkrant, June 8, 1991, Amsterdam (NL).
  • This article discloses a sound-absorbing road surface made of "highly open asphalt concrete” (ZOAB), in which a two-layer structure (“TWINLAY”) is proposed to avoid clogging of the pores due to sludge formation, etc.
  • the covering consists of a 1.5 cm thick surface layer with a grain size of 4 to 8 mm and an underlying 5 cm thick layer with a grain size of 11 to 16 mm.
  • EP-A-0 471 978 also discloses a water-permeable surface fastening element made of mineral grains bonded with binders with the release of continuous pores.
  • the element has a two-layer structure with a thinner facing layer and an underlying thicker layer.
  • the mean free passage cross section of the facing layer is smaller than the mean free passage cross section of the layer below.
  • the invention aims to provide a floor surface fastening of the type mentioned, which has an improved throughput in terms of water permeability, but at the same time retains the advantages of the known constructions with regard to avoiding a laying of the pores.
  • the solids contained in the surface waters can only penetrate into the soil element up to a certain grain size; however, due to the increase in the free flow cross-section, they are not retained in the base element, but are carried into the substructure.
  • the ventilation of the sub-floor is retained after the floor surface has been fixed.
  • the solids retained on the surface of the floor surface fastening or the floor element can be easily picked up and removed.
  • the pores on the surface as well as inside cannot become overgrown due to dirt particles, so that the drainage effect and the biological degradation activity are retained within the surface fastening and also in the sub-floor.
  • the cleaning and maintenance of the sewage shafts and sewers is reduced to a minimum. In addition, amphibians no longer get into the sewage shafts.
  • the invention enables the execution and erection of walkable and passable surface fastenings for squares, streets and road sections as well as for converted surfaces, e.g. to form a bandage, this surface fastening directly on a mechanically stable base layer, e.g. Split, inclined concrete or water-permeable floor substructure (e.g. ballast bed) can rest.
  • the floor elements can be drained into the substructure or via drainage pipes, in which the leachate or other liquid media are fed to a central collector.
  • openings can also be formed in the individual floor elements, which are arranged in such a way that in the surface fastening they result in channels oriented transversely to the flow direction, in which the infiltrating liquid, insofar as it cannot be adsorbed, flows away.
  • the invention also relates to a floor element for producing a floor surface fastening, which has the features described in connection with the floor surface fastening and has such an outline shape that it can be used e.g. can be laid seamlessly.
  • the floor surface fastening or the floor element according to the invention can be made of single-grain or multigrain concrete or similar porous materials, such as e.g. Plastics, asphalt mixtures, etc.
  • the floor elements can be placed on a corresponding sub-floor.
  • the porous material is preferably surrounded and held by a frame body, the frame opening of which tapers from top to bottom, as is known per se from AT-PS 391 629 in connection with other floor elements.
  • the additionally molded, downwardly widening channels compensate for, or even outweigh, the decrease in the free flow cross section in the downward direction, which is due to the frame opening tapering downwards.
  • the cover layer 1, i.e. the first layer forming the inlet upper side of the floor element or filter stone has only a limited layer thickness d1 in the flow direction, the idealized free flow cross section a of layer 1 (see FIG. 2a) depending on the composition of the inlet or the layer forming the layer Multigrain concrete or another porous material, such as plastic, also has a defined size.
  • a two-layer floor element with a frame body 4 is shown to improve the static strength properties of the floor element.
  • each of the following layer 1 in the flow direction D Layer (s) 2, 3 ... differs from the first layer 1 in that the free flow cross-sections are each larger than the free flow cross-sections of the previous layer, which is achieved in that for the production of layers 2, 3. .. for example, an increasingly coarse-grained one- or multi-grain concrete is used. In any case, it must be ensured that in the flow direction D the spaces between the grains produce increasingly larger free flow cross sections b, c ... It is also essential that the thickness d1 of the first layer 1 is significantly smaller than the thickness d2 or d3 ... of each further layer 2, 3 ...
  • Free flow cross-sections a, b, c ... with increasing dimensions in the flow direction D, as shown in Fig. 2b, are additionally mechanically formed using suitable manufacturing processes, e.g. through conical or stepped or corrugated mandrels etc.
  • the floor element can be produced with a support or frame body 4 according to FIG. 1b to increase the strength or load-bearing capacity, as is also described in AT-PS 391 629.
  • the frame body With lower strength requirements, such as walk-in surface fastenings with a corresponding substructure, the frame body can be omitted.
  • the outline of the individual floor elements is the simplest rectangular or square, but other shapes, which can preferably be assembled without gaps to form a floor surface, can also be used, as are shown by way of example in FIGS. 4 and 5.
  • the size of the floor elements is not restricted and can be selected depending on the manufacturing process or also on the transport and insertion devices.
  • each layer of the floor element is made, for example, from a predetermined single-grain or multigrain concrete or similar materials.
  • the free flow cross-sections a of layer 1 those solids in surface water that are larger than this flow cross-section a are retained on the surface of the base element.
  • the free flow cross-section b in the flow direction D is larger than in the previous layer 1. This ensures that solid particles which have already penetrated into layer 1 are no longer retained in layer 2 can.
  • the free flow cross-sections a in the first layer 1 of the floor element cannot be blocked by dirt parts, because due to the fluctuations in moisture and dryness, the dirt particles experience volume changes and are subject to pressure fluctuations due to driving on the surface of the floor element, which the dirt particles penetrate into the underlying (n) Promote shift (s). Because of the larger free flow cross sections, the particles can be transported from this layer or these layers without hindrance.
  • Layer 1 expediently has only a minimal layer thickness d1 in order to avoid penetrating solids already being deposited in layer 1. In theory, therefore, it is not possible to lay or overgrow the floor element.
  • the invention can be modified in various ways, in particular with regard to the shape and size of the floor elements or the floor surface fastening, which can be provided with a smooth, rough or otherwise structured surface, as defined in the appended claims.
