'* Plastic grid tile

Räster tile made of plastic for pesting and making it passable, of lawns. '

The durability of lawns is heavily dependent on the respective weather, i.e. on whether the soil is dry or damp or is wet. Therefore, lawns are not readily suitable as permanent parking areas for motor vehicles. . . '

Openwork concrete blocks have already been developed with which the parking area is laid out. The openings are filled with topsoil and then lawn is sown. '

Due to the strength properties of the concrete, it is later The area of the perforations overgrown with turf is relatively small in relation to the total area, so that the turf appears to be patchy. . To remedy this disadvantage is the task of the present one Invention. '■

This object is now achieved in that between a frame made of a circumferential, downwardly open U-profile several narrow webs are arranged. ■

With the help of the figures, two exemplary embodiments are shown explained.

FIG. 7 shows this embodiment in plan view

The grid tile consists of the relatively wide, circumferential frame 1 which, as FIG. 2 shows, has the shape of a TJ profile that is open at the bottom. The grid tile shown here is divided into four fields by TJ profile webs 2 of the same type, but with a smaller cross-section, which in turn are divided by ^! simple narrow fo webs 3 are traversed in a diagonal direction. . '·

* To form-fit around adjacent grid tiles to be able to connect, are in the frame T on the outside of two adjacent Sides torn-tail-shaped projections, while on the other two sides in the outer leg of the U-shaped frame 1 corresponding recesses

5 (Figure 2) are cut out * The U-profile-shaped frame 1 is made more torsion-resistant in the corners by diagonal ribs 6 (Frgur 3;). These ribs 6 are arranged in such a way that the dovetail-shaped projections 4 grip behind these ribs β when the f ■ Rauterfliesgn is being laid.

* Both the dovetail shaped projections 4 and the

corresponding recesses 5 are in the lower area of the grid · Tile arranged so that after laying either of adjacent grid tiles or of the topsoil or the Gfrasnarbe be covered. In the dovetail-shaped projections 4 openings are provided to allow the grid tiles to be To anchor pegs 7 (Figure 4) in the ground better '.

The surface is roughened so that it is safe to walk on, i.e. grooved or provided with warts. · '■ ■

f It is also thought to weight down the plastic grid tiles and make them stiffer by using the U-profile

Fe-shaped frame 1 and possibly also the webs 2 with concrete, --Mor - '* ¹ ' tel or cast resin. This filling is marked in Figure 4 dxirch -8. ■

Figure 5 now shows schematically how the grid tiles described above are laid interlocking with each other. After laying, they are filled with mother soil and lawn sown.

In the figures β and 7 another embodiment is shown, in which the U-shaped frame 11 is not up to the. surface

$ * comes, but is surmounted by the webs 12 forming a network. In this embodiment, it is advantageous to have the web network 12

** genüber the frame 11 is placed to arrange, in order to facilitate installation and einerseits'ein height equal to the other part of production engineering ¹ light perforations 13 to the irrigation and drainage of the arranged above the frame 11 Rasterfelder_anbringen.

Not only by the color of the plastic grid tiles .Even a strange effect can be achieved, it is also possible to fill the individual Rasterfeider with different colored mortar or · j G-ießharz and to create a kind of mosaic.
