Composite installation of lawn or ground fixing panels

at embankment crossings

The invention relates to the installation of known plastic lawn or ground fixing panels at slope transitions and similar terrain situations.

The known plastic lawn and ground fixing panels have a honeycomb grid structure formed in one piece with a floor wall pierced by drainage openings or with floor wall elements, preferably with hexagonal or other grid cells, and are provided with interlocking form-locking elements on their panel edges in order to be able to lay the panels in a composite manner, with the adjacent panels hooking together at their edges to counteract separation in the laying plane as well as mutual height offsets. Such panels can be used to fix lawns by filling the grid cells with soil or substrate and then sowing grass, but they can also be used for other ground fixing, for example on roadsides, embankments and drainage areas, to fix the upper layer of soil and prevent it from slipping or being washed away.

When laying such soil stabilization plates at slope transitions, i.e. at transitions between a roughly horizontal or slightly inclined ground surface and an inclined or more strongly inclined slope surface,

The problem is that the panel bond is interrupted along the bend line of the ground. The dome elements on the edges of the panels only allow the panels to be laid in a bond if they are laid flush with the surface. This means that at slope transitions, the panels on the slope surface can be laid in a bond, as can the panels on the adjacent, roughly horizontal surface, but along the slope bend line, the two panel bonds meet without being connected.

The invention is therefore based on the object of creating a possibility for the composite installation of ground reinforcement plates even over terrain bend lines.

This object is achieved according to the invention by the arrangement specified in claim 1. Advantageous embodiments and further developments of the invention are the subject of the dependent claims.

An embodiment of the invention will be described in more detail below with reference to the accompanying drawings. In the drawings:

ten view.

Figure 1 shows a perspective view of a known lawn and ground fixing plate. This is

"LQ plastic injection molded part and consists of a bottom wall and a honeycomb wall grid connected to it in one piece to form a number of grid cells, each grid cell having a circular drainage opening in the bottom wall. At the edges of the bottom mounting plate

J ₅ coupling elements are arranged which couple the panels together in a form-fitting manner when they are laid in a flat connection. This coupling of adjacent panels is only possible if the panels can be laid flush within certain tolerances. It is not possible if

2Q neighboring plates form a significant angle with each other, as occurs at slope transitions in the terrain.

Figures 2 and 3 show a top view and a side view, respectively, of a coupling plate 1 made of plastic, just like the plates themselves, which is flexible over a large angular range both through the appropriate choice of material and through design measures.

The coupling plate 1 has, at its opposite end portions, upwardly projecting groups of elastic locking claws 2 which can each be pressed into a locking manner through openings in the bottom wall of a plate of the type shown in Figure 1 near the edge of the plate.

The central area of the coupling plate 1 is designed with a wave-like profile 3 which increases flexibility, so that the coupling plate can be bent into an angular shape as required during use, in which its two ends

areas form an angle with each other. In this way, as shown schematically in Figure 4, plates of the type shown in Figure 1 can also be coupled together at slope transitions, so that they can be arranged at a defined mutual distance at any angle depending on the terrain and can be held firmly together, so that the angled plates cannot drift apart or be pushed together by external influences and thus a much better fixation and stabilization of the soil areas or, for example in drainage ditches, corresponding gravel or crushed stone fillings can be achieved.

In the embodiment shown, the coupling tab has two pairs of locking claws arranged at an appropriate distance on at least one end area for locking into two adjacent base plate openings of a plate. This increases stability and also secures the coupled plates against relative displacement in the direction of the coupling joint.

It goes without saying that the locking claw 2 on the coupling bracket can be replaced by other locking means with the same effect, for example ring bead segments/locking fingers, locking lugs and the like, or that locking elements are not arranged on the coupling bracket at all, but on the underside of the base wall of the floor fastening plates to be coupled. It is only important that locking elements are arranged between the coupling bracket and the base wall of the plates to be coupled on one part, which can be locked into corresponding openings or opening elements on the other part.

Claims (4)

1. Arrangement for laying lawn or soil fixing panels coupled in a mutual connection in the area of slope transitions, with flexible or flexurally elastic coupling straps for coupling adjacent panels forming an angle with one another and for simultaneously maintaining a defined distance between the adjacent panel edges of the coupled panels, and with elements ( 2 ) arranged on the one hand on the coupling straps ( 1 ) and on the other hand on the panels to be coupled and counter elements for producing a locking connection between an end region of the coupling strap resting on the underside of the floor wall of one of the panels to be coupled and the panel in question. 2. Arrangement according to claim 1, wherein the elements and counter-elements for the latchable connection of the coupling tab and the plates to be coupled are formed by latching claws ( 2 ), latching fingers or annular bead segments formed on the upper side of the coupling tab ( 1 ) and by opening edges of bottom wall openings of the plates to be coupled. 3. Arrangement according to claim 1 or 2, wherein each coupling tab ( 1 ) can be locked to at least one of the two adjacent plates to be coupled at two locations spaced apart along the edge of the plate. 4. Arrangement according to one of claims 1 to 3, wherein each coupling plate ( 1 ) is provided in its central region with a design which increases its flexibility in the form of half-waves or wave-like wall segments ( 3 ) or local wall thinnings.
