Definitions

  • the invention relates to a water-permeable surface fastening element for traffic areas according to the preamble of claim 1.
  • Traffic areas are understood to mean in particular roads, paths, parking lots, courtyards and terraces, traffic being understood to mean both motor vehicle traffic and traffic with bicycles or people.
  • Surface fasteners are understood to be, in particular, paving stones or path slabs, with or without interlocking.
  • Water-permeable surface fastening elements have therefore already been developed, which in turn have to be installed on a water-permeable substructure.
  • the water permeability also requires air permeability.
  • the invention relates to a development of such surface fastening elements.
  • the invention is based on a water-permeable concrete paving stone on the market with the features of the preamble of claim 1.
  • Known surface fasteners of this type generally have a relatively coarse-grained structure with a rough surface and coarse pores extending to the surface.
  • Surface contaminants including contaminants washed up by precipitation, gradually set these as coarse Pores, so that the water and air permeability decreases significantly over time and is ultimately no longer guaranteed in the limit. Since such contamination extends into the depth of the stone body, it is difficult or impossible to flush it out.
  • the rough surface causes a relatively high rolling resistance and thus not only a braking effect, for example on bicycles, but also generally a relatively high traffic noise. Even pedestrians find walking on rough artificial stone surfaces uncomfortable, for example because of the danger of getting caught while walking.
  • the invention is therefore based on the object of creating a water-permeable surface fastening element which is less sensitive to dirt, possibly even cleanable, and has a lower rolling resistance.
  • the relatively fine, continuous pores of the facing layer have a filtering effect with regard to contaminants.
  • Coarser contaminants are retained on the top of the surface fastening element and can be easily swept away or washed away there.
  • Finer contaminants, which penetrate into the continuous pores of the facing layer are gradually taken into the coarsely structured substructure at least to a large extent under the effect of the rainwater and can seep into the substructure there together with the rainwater. This drastically reduces the risk of clogging of the entire surface fastening element.
  • a side effect of the more pore-shaped formation of the facing layer even if one does not explicitly provide additional smoothing measures for the surface (see claim 13), a reduction in rolling resistance and thus a reduction in the other negative effects mentioned in connection with rolling resistance.
  • Facing layers are known per se in the case of non-water-permeable surface fastening elements, e.g. for decorative design of the surface.
  • the "pore diameter” is understood here to mean the largest possible diameter of a ball that just fits into the pore or can “slip” through it.
  • Average pore diameter is the average of the pore diameters of all pores in the body or the facing layer. According to the literature, the "average pore diameter” for a single-grain concrete is approximately 0.24 x average grain size, which is to be understood as the mean value of the grain group used according to DIN 4225 Part 1.
  • claim 2 defines preferred pore diameter ranges which give the desired filter effect mentioned while reducing the risk of clogging but maintaining the water permeability.
  • the strengths of claims 3 and 4 and of claim 8 are coordinated.
  • Claims 5 to 7 relate to preferred material selections in the context of a production of the surface fastening element according to the invention from the usual basic materials.
  • a binder based on epoxy resin can be used as the binder based on plastic.
  • the surface fastener according to the invention is modified with respect to the body so that the mineral grains are formed by the binder to an inherently water-impermeable body in which continuous pores are formed as through channels.
  • the facing layer which is then more porous in comparison to these channels, distributes the absorbed liquid together with the absorbed micro-dirt particles to the individual channels, which can be provided with a lower surface density than otherwise in a body of the known type with pore formation between the individual grains.
  • the invention also relates to the use of a high-pressure water jet method for flushing the continuous pores of the facing layer in the traffic area composite of the area fastening elements. It has been shown that the inevitable slow addition of the facing layer according to the invention can be remedied by appropriate flushing, so that, unlike the known water-permeable surface fastening elements, the surface fastening elements according to the invention can also be regenerated in the application.
  • High-pressure water jet is understood to mean a water jet in particular in a pressure range of 20 to 40 bar, i.e. a very common area for such high pressure water jet processes.
  • the average grain size (see e.g. Claim 8) is based on the mean value of the grain group according to DIN 4226.
  • a surface fastening element 2 is composed of a body 4 located at the bottom and an upper facing layer 6 which is thinner than the body.
  • the top 8 of the facing layer forms an element of a traffic area to be produced.
  • the body 4 is laid on a water-permeable substructure, not shown.
  • the body 4 and the facing layer 6 each have approximately the same thickness over the respective cross section shown, so that the top 8 of the facing layer, the underside 12 of the body 4 and the boundary layer 10 between the facing layer 6 and body 4 form essentially flat parallel surfaces.
  • the top side 8 is expediently designed to be smooth, while the boundary layer 10 between the facing layer 6 and the body 4 expediently represents only an ideal surface which in practice describes a form-fitting engagement of the facing layer 6 and the body 4.
  • the underside 12 of the body 4 can also be structured rough to jagged.
  • the facing layer 6 consists of mineral grains 14, the respective surface 16 of which is covered by a binder, not shown, so that a structure in the manner of a single-grain pore concrete is formed.
  • the space between the mineral grains 14 is not completely filled with binder, but the binder serves essentially only for the superficial mutual bonding of the mineral grains 14 to one another, a largely coherent mesh of open pores being formed in the space.
  • vertically continuous pores 20 are formed in particular from the top 8 of the facing layer 6 to the boundary layer 10.
  • FIGS. 1 and 2 differ in the following:
  • the structure of the body 4 is basically the same as that of the Front layer 6, with the only exception that the mineral grains 22 of the body 4 have a substantially larger grain size than the mineral grains 14 of the front layer 6.
  • the mineral grains 22 are bonded to one another on their respective surface 24 by a binder (not shown).
  • the continuous or open pore mesh of the facing layer and the continuous or open pore mesh of the body must communicate at least in the vertical direction; therefore, even when connecting the facing layer and body in the interface 10, the binder should only be used sparingly, insofar as it also connects the facing layer 6 and body 4 to one another.
  • the vertical pores 20 of the facing layer 6 must communicate with the vertical pores 28 of the body 4. Due to the larger grain size of the mineral grains 22 in the body, the averaged free passage cross section of the vertically continuous pores 28 of the body is also larger than that of the vertically continuous pores 20 of the facing layer 6.
  • mineral grains that are still used are instead formed by the binder to form an otherwise dense body 30, in which instead of the vertically continuous pores 28 of the exemplary embodiment according to FIG. 1, vertical vertical ones run from top to bottom Channels 32 are preformed, which have a significantly larger passage cross section than the vertical pores 20 of the facing layer 6 and also a larger one Passage cross section than the vertical pores 28 of the body 4 of the embodiment of FIG. 1 can have.
  • a substantially smaller number of vertical channels 32 in the embodiment of FIG. 2 than in the case of vertical pores 28 in the embodiment of FIG. 1 are sufficient. No preformed channel analog need be provided for the horizontal pores 26 of the embodiment of FIG. 1.
  • the vertical channels 38 are distributed over the horizontal cross-sectional area of the surface fastener so that the water entering the body 4 through the pore mesh in the facing layer 6 is discharged as evenly and as completely as possible to the underside 12 of the body 4, even in the second embodiment of FIG. 2 becomes.
