Definitions

  • the invention relates to a system for the heavy-duty fastening of outdoor surfaces, comprising a number of profile grid components that can be connected to one another and a surface fastened therewith.
  • Such components made of plastic are for example from DE 195 29 473 C1 known.
  • the profiled grid component referred to as a multi-purpose component is divided into individual surface sections which are connected to one another by spring elements which are integrally molded into the multi-purpose component.
  • the spring elements are designed in the form of a band and also in the form of loops, which means that the multi-purpose components can be largely flexible and still firmly bonded to one another.
  • the multi-purpose components have hook-shaped coupling devices for releasable connection with one another. All surface sections of the multi-purpose components are designed to be open and can be filled with earth or gravel after laying.
  • the invention is now based on the object of creating a system for the heavy-duty fastening of outdoor areas by means of interconnectable profiled grid plates, which can be introduced into the ground by means of rollers and / or vibration, in particular on lawns or meadows, and interlock with the subsurface and paved the area, making it passable but not sealing it.
  • the system for fastening comprises a number of interconnectable profile grid components which have coupling elements and recesses for receiving the coupling elements on the outer circumferential side surfaces, the profile grid components being formed in rows alternating from running surface sections and hollow sections, wherein the tread sections and hollow sections are offset in rows, and the tread sections are surrounded by four side end faces and are connected to one another with a connecting section and half tread sections are alternately arranged on the outer sides, these forming a whole tread section when the profile grid components are assembled.
  • the profile grid components can have a square or a rectangular shape and consist of a plastic.
  • connection between the profile grid components can be done in two ways.
  • mushroom-like connecting elements and two elastic resilient noses are arranged on each half of the running surface section and latching openings for receiving the mushroom-like connecting elements are arranged on half of the running surface sections of the opposite side areas.
  • the half running surface sections arranged on the side surfaces of the profile grid components have latching openings with two elastically resilient lugs, in which connecting elements with two mushroom heads arranged at the ends can be locked in each case to connect adjacent profile grid components.
  • the spring-loaded noses arranged on the half running surface sections can completely absorb material expansions as expansion elements or can act as an elastic connection between the profile grid plates.
  • hook-shaped members are arranged on the underside of the side end faces surrounding the hollow portions between the tread portions. If the hollow sections are provided with intersecting webs in the interior, hook-shaped elements can also be arranged at the intersection.
  • the profile grid components When the profile grid components are introduced into an outdoor area, preferably a lawn, they are connected to one another, placed on the surface and pressed into the ground by means of vibration rollers. Due to the special design on the underside of the profile grid components, on which hook-shaped elements are arranged, the profile grid components get caught in the roots of the lawn and thus prevent the take-off from the ground or the subsurface when aircraft take off due to the resulting negative pressure.
  • the running surface sections of the profile grid components are provided with openings and knobs.
  • the openings can assume regular or irregular geometric shapes. Water can seep in through the openings, which prevents the roots from dying off and the profile grid components from loosening from the subsurface. When aircraft are landing or taking off, a negative pressure is created below the wings, which means that loose profile grille components can be lifted and the profile grille component surface detach from the ground.
  • knobs on the surface of the tread sections of the profile grid components results in an improvement in the rolling resistance of around 20% compared to the pure lawn area.
  • the individual profile grid components are designed on their upper and lower sides in such a way that they can be easily releasably latched to one another when stacking individual profile grid components or pre-connected connections.
  • the upper shape of the surface of the profile grid components is provided with recessed sections into which protruding hook-shaped elements arranged on the underside can be received.
  • the area paved with the system is a flight operations area, in particular a taxiway and / or landing runway, the subsurface of which is a lawn or meadow area.
  • the system composed of the individual profile grid components, whereby the individual profile grid components can be put together by means of the connecting elements that engage in corresponding locking openings, are placed on the outdoor surface and introduced into the ground by means of rollers and / or vibration.
  • the flight operations area equipped with it has a CBR value, which in an experiment determines the load-bearing capacity of the ground, in a range from 9% to 30%, preferably a CBR value in the range from 19% to 24%.
  • the basic load-bearing capacity after the system according to the invention has been introduced is between 35 and 125 MN.
  • the Figure 1 shows the profile grid component 1 in a perspective view in plan view.
  • the profile lattice component 1 comprises running surface sections 2 and open sections 3, which are offset in rows, the running surface sections 2 being surrounded by four side end surfaces 7 and the running surface sections being connected to one another by means of the connecting sections 6 in such a way that the open section 3 results.
  • half running surface sections 2a are arranged, on which either a connecting element 8 or a latching opening 10 are provided.
  • the running surface sections 2 lie on the side of the profiled grid component 1 facing away from the laying ground.
  • knobs in the form of truncated pyramids are provided, which bring about an improvement in the rolling resistance. Furthermore, openings are provided in the surface of the tread sections 2 through which the surface water enters the underlying root areas of the lawn can penetrate in order to prevent the root system from dying off. At the same time, the ground below the running surface sections 2 is also ventilated.
  • the connecting elements 8 are designed in the shape of a mushroom head and, together with the noses 9, create an elastic connection between the profile grid components and can thus also compensate for linear expansions due to temperature fluctuations.
  • the Figure 2 shows the profile lattice component 1 in a perspective view in the view from below.
  • Hook-shaped elements 11 are provided on the side end faces 7. These serve to anchor the profile grid components 1 after rolling into the lawn in the root system.
  • the Figure 3 shows a section of the profile lattice component 1 in the view from below.
  • crossbars 12 for further stabilization can be arranged in the spaces of the running surface sections 2 and / or the open sections 3.
  • hook-shaped elements 11 are arranged, which serve to anchor the profile grid plates 1 in the ground.
  • paved taxiways or landing runways are used as flight operations areas, which are characterized by an improved rolling behavior of the aircraft compared to pure grass or lawns and shorter take-off routes. Furthermore, the sinking of the aircraft in bad weather is reliably avoided.
  • the elastic arrangement of the profile grid components ensures a stable basis for the taxiways and take-off runways as flight operations areas as well as their necessary adhesion.
  • a particular advantage of the system according to the invention is that the profile grid components are rolled into the existing subsoil, such as lawn or grass areas, and the grid plates are not laid on the surface, as described in the known prior art, and then filled with topsoil, for example, and planted become.
  • the individual profile grid components 1 are designed on their upper and lower sides in such a way that they can be easily releasably latched to one another when stacking individual panels or pre-assembled connections.
  • the upper shape of the surface of the profile grid components 1 is provided with recessed sections 13, in which protruding hook-shaped elements 11 arranged on the underside can be received.
