Description

The invention relates to a floor covering system, comprising a positioning grid, wherein the positioning grid has first and second webs which intersect each other, wherein the first webs have on their underside a plurality of first insertion openings and the second webs have on their upper side a plurality of second insertion openings, wherein at a crossing point of the first and second webs engage in such a way that a first web is inserted into a second insertion opening and a second web in a first insertion opening. Moreover, the invention relates to a method for assembling a floor covering system.

Barred lattices are used, for example, as a vegetation fixture. Thus, the G 85 27 295 shows a vegetation lattice, which is composed of a plurality of webs. The individual webs have insertion openings arranged at defined intervals, which each extend over half the height of the web. If the webs are arranged perpendicular to one another and crossing each other, they can completely engage in one another by means of their insertion openings. This makes it possible to join the first and second webs together to form a vegetation lattice stone. The grid thus formed has a plurality of open spaces in which plantings introduced into it can find a livelihood and, moreover, be securely held in position. A field of application of such vegetation lattice stones is the greening of embankments to be fixed, in particular also at steeper slope angles.

In a similar way composed of webs is the from the DE 50 2008 015 024 known lawn grid mat. Here, too, intersecting webs form a lattice structure in whose interstices vegetation can be used or grass can grow in. If the webs are formed from an elastomer, these lawn grid mats are suitable as fall protection coverings.

A disadvantage of these lattice structures with vegetation vegetation is that they can fix a loose ground, but the vegetation used therein is not suitable for withstanding a strong and permanent load.

The object of the invention is to propose a floor covering system which has grown to a strong and durable load and which can be adapted flexibly to the respective conditions.

This object is achieved with the flooring system according to claim 1. Some advantageous embodiments of the flooring system according to the invention are mentioned in the subclaims. The inventive method for assembling a floor covering system is set out in claim 10.

A basic idea of the invention is that the intersecting first and second webs define a free space into which a paving stone is inserted. According to the invention thus formed by the webs positioning grid is not used for the insertion or growth of vegetation, but for the positioning of a paving stone. Thanks to the simple structure of the webs, the positioning grid can be assembled quickly and its outer shape easily adapted to the local conditions. The composite grid then serves as a positioning aid for the paving stones. The grid makes it possible to arrange the paving stones at predetermined locations and at certain distances from each other to a floor covering. Such a floor covering is much better suited to a strong and permanent load, as occurs for example on driveways, than a lattice covered with vegetation.

Another basic idea of the invention is that the floor covering grid according to the invention is a particularly simple method for assembling a stable floor covering. For this purpose, it is only necessary in a first step to assemble the first and second webs into a positioning grid and, in a second step, to insert the paving stones into one of the free spaces in the positioning grid thus formed.

In an advantageous embodiment of the paving stone is at least substantially only on a surface of the flooring system. In this case, a vertical force acting on the lining side of the paving stone can be introduced directly into the subsoil. Accordingly, the webs or the web foot need not be designed to accommodate such a burden. In the event that the paving stone also rests on the foot of the webs, it is advantageous if the bottom of the paving stone in this area has a recessed heel, the return ideally corresponds to the strength of the web foot. This ensures that at least a large part of the load from the paving stone can be dissipated directly into the substrate.

It is particularly advantageous if the paving stone is higher than the webs, so that it protrudes into the positioning grid beyond the webs. With this arrangement it is ensured that the webs are not for it must be designed to absorb forces acting perpendicular to the lining side of the paving stone. As a result, they must be less stable and / or can be made of less stable materials.

Moreover, it is advantageous if a gap is formed between the paving stone inserted into the free space and the first and second webs laterally delimiting the free space. The joint facilitates the drainage of water on the pavement in the direction of the ground. At the same time it facilitates the insertion of the paving stone in the lattice opening respectively the space supplemented by the webs.

It is advantageous if viewed in the longitudinal direction of the webs, the lengths of the first and second insertion openings are different. As a result, the nesting of the first and second webs is facilitated. Moreover, it is advantageous if the length of one of the first and / or the second insertion openings runs conically towards the inner end of the insertion opening. This also facilitates the assembly of the webs.

In a further preferred embodiment, the lining side of the paving stone is convex. The convex shape facilitates water drainage to the bars. In addition, it makes the flooring system look like an old plaster.

The paving stone is preferably formed from polyurethane-bound rubber granulate, in particular from EPDM rubber granules and / or recycled rubber granules. Such materials have the advantage that on the one hand they are stable enough to cope with heavy loads, on the other hand allow the setting of a certain elasticity. Furthermore, their porosity improves the water drainage into the ground.

In particular, a manufactured paving stone may have a cavity, in particular a cavity which is open toward the ground of the floor covering system. This brings a certain amount of material savings. If the paving stone made of rubber granules, the cavity also has other advantages. The position and / or size of the cavity has an influence on the material thickness of the lining side of the paving stone and thus determines its elasticity. The shape of the cavity can therefore be used for the interpretation of the elasticity of the paving stone. In addition, it has an effect on the infiltration rate.

In a particularly preferred embodiment, the paving stone is formed higher than the webs so that it protrudes into the positioning grid beyond the webs. This makes it possible to design and certify the flooring system according to the invention as a fall protection coating, without the need for this purpose, the webs must have a corresponding elasticity. A fall on the pavement is already cushioned by the elastic paving stone before contact with the webs comes about. Regardless of the fall protection benefits, the clearance formed by the recessed lands between two paving stones can settle over time, creating a natural feel to the flooring.

Preferably, the first and second webs of a plastic, in particular polyamide, or a glass fiber reinforced plastic formed. The floor covering system according to the invention ensures that, depending on the embodiment, only little or no forces acting perpendicular to the covering surface have to be dissipated via the webs. A bridge made of plastic has sufficient stability for this purpose. At the same time it is easy and inexpensive to manufacture. Depending on the position of the floor covering system, it may also happen that not only forces acting perpendicularly on the covering but also forces acting at an angle thereto must be dissipated. Here it may be necessary to choose a glass fiber reinforced plastic material as the material for the webs instead of a simple plastic.

In a particularly preferred embodiment, the first and second webs form a downwardly open, at least approximately U-shaped profile, wherein the ends of each leg pass into a standing surface which projects at least approximately at right angles from the leg. Such a profile is particularly easy to manufacture.

In a preferred embodiment, the sum of the depths of the first and second Einsteckcköffnung is greater than the height of the first and second web. This ensures that the two end edges of the first and second insertion opening do not lie on one another after the first and second webs are plugged together. This prevents wear caused by friction or pressure generated breakage of the webs at their crossing point.

A particular advantage of the floor covering system according to the invention is that it does not require a specially processed substrate or substructure. Ideally, the surface is as level as possible, but further properties are not required.

The Indian 1 shown first bridge 1 has an upside down, U-shaped profile, whose two legs 2 or. 3 in each case a footprint, which in the further than foot 2a or. 3a be referred to, pass over. The two feet 2a and 3a are relative to the thighs 2 and 3 set in at least approximately a right angle and form a respective outwardly extending footprint of the first web 1 out. The stand ensures a secure stand of the first bridge on the ground.

At the feet 2a and 3a opposite end of the thighs 2 and 3 These are connected via a semicircular first intermediate element with each other. In the preferred embodiment described here, the web has a material thickness of 2 mm, is 36 mm high and 60 mm wide from foot to foot. The axially symmetrical to an axis A trained first ridge 1 has a width of 20 mm at the transition between legs and feet, which tapers towards the top. Between the two thighs 2 and 3 runs a first reinforcement 4 whose special features will be explained later.

The in 2 shown side view of the first bridge 1 can be seen that the bridge 1 in the course of its longitudinal side a plurality of spaced apart first insertion openings 5 on. The insertion openings 5 are down, ie towards the ground, open. They taper upwards, thus forming a kind of truncated cone. In a preferred embodiment, they are 20 mm wide at the bottom and taper at their top to 16.74 mm. Overall, the bridge is 1000 mm long, has five first insertion openings 5 on, with the first insertion 5 equidistant from each other. The distance between the respective insertion openings 5 to the respective end of the first bridge 1 is half the distance between two insertion holes 5 ,

According to the supervision 3 it can be seen that the first bridge 1 Also formed in the longitudinal axis is axisymmetric. The course of the feet 2a and 3a is in the area of the insertion openings 5 interrupted. This allows easy assembly of the first web 1 with the second bridge explained below. In the of the 4 shown sectional view are the inside between the two legs 2 and 3 running first reinforcements 4 shown, which respectively in the longitudinal direction in front of and behind an insertion 5 are arranged. The first reinforcements 4 are integral with the thighs 2 and 3 and the first intermediate element connecting them 6 educated. They improve the stability of the first bridge 1 , the distance between the two of an insertion 5 associated first gains 4 is 60 mm in this embodiment. For a better illustration of the circular section B from the 4 in an enlarged form in the 5 shown.

The in 6 shown second bridge 7 corresponds in its side view with its total U-shaped profile, the second intermediate element 9 , the two thighs 10 with their stands or feet 10a in the side view of the first bridge 1 , In this respect, here on the zu 1 explained be referenced. The first and second bridges 1 . 7 are not arranged head to head when assembled to a positioning grid, so not perpendicular to each other, but in a plane that runs at least substantially parallel to the ground. Thus, both webs can improve the feet on the ground 2a . 3a . 10a form.

At its top, the second bridge 7 five second insertion openings 8th on. The insertion openings 11 extend over the entire width of the second intermediate element 9 and protrude down into the area of the thighs 10 of the second bridge 7 into it. The arrangement of the insertion openings 11 in the longitudinal course of the second bridge 7 corresponds to the first insertion 5 in the first jetty 1 , The insertion openings 11 are each 15 mm long, so shorter than the first insertion openings 5 , This will be a simple mating of the first bridge 1 with the second bridge 2 guaranteed.

The the 8th to be taken view of the second bridge 7 from the top shows that the second bridge 7 in its longitudinal alignment is also formed axially symmetrical. Here too are the feet 10a in the area of the second insertion openings 11 interrupted. The breaks are shorter than those in the first bridge 1 , which is due to the easier assembly.

In the sectional view according to 9 are in the longitudinal direction of the bridge 7 in front of and behind the second insertion openings 11 arranged and this limiting second reinforcements 12 arranged. The second twelve reinforcements also serve to improve stability.

The 10 shows one of a plurality of first webs 1 and second bridges 7 composite, in this way arbitrarily expandable positioning grid 13 , The already described features of the first webs 1 and second bridges 7 with their coordinated first 5 and second 11 Insert openings allow positioning grille 13 to assemble in a simple way. In the embodiment shown here, the first and second webs are arranged at right angles to each other, so that from the positioning grid 13 formed open spaces 14 due to the arrangements of the first and second insertion openings 5 . 11 have a square shape. Just as the units of measure set forth here are given by way of example only for a particularly preferred, mutually co-ordinated embodiment, that of the positioning grid 13 have another quadrangular or even any shape with at least three corners.

In four open spaces 14 of the positioning grid 13 are paving stones 15 used, which, as in the representation of the section EE according to 11 can be seen, a cavity open to the ground 16 and on its lining side 17 stand out over the bars. Also good to see is that the first and second bars 1 . 7 are the same height. For better clarity of the described individual features is with the 12 still an isometric representation attached.
