[0001] Plastic multi-purpose system for irrigation and / or drainage and its use

[0002] Description

[0003] The present invention relates to a plastic multi-purpose system for irrigation and / or drainage and its use.

[0004] background

[0005] State-of-the-art plastic grid components are known, which can be used as a flat composite for ground stabilization, as a foothold for animals, or even on roofs for green roofs. Such plastic grid components often prove disadvantageous in practice, as plant growth in open spaces made almost impossible by the plastic multi-purpose components, particularly during hot, dry periods. The goal of holistic greening for visual enhancement and the creation of additional habitats for insects and soil organisms is missed.

[0006] Task

[0007] It is therefore the object of the present invention to provide a plastic multi-purpose system for irrigation and / or drainage which can be used in a multi-functional way. It is also the object of the present invention to provide a plastic multi-purpose system for irrigation and / or drainage which can be used permanently even when subjected to heavy traffic. It is also the object of the present invention to provide a plastic multi-purpose system for irrigation and / or drainage which can be produced cost-effectively. It is also the object of the present invention to enable reliable and permanent water control for roofs and floors so that the soil fauna is strengthened and new habitats for insects are created.

[0008] Solution

[0009] The problem is solved by the technical features specified in claim 1.

[0010] The core idea of ​​the present invention is to provide a plastic multi-purpose system for forming a planar composite for floor areas and / or roof areas with at least one cable routing means and at least one plastic grid multi-purpose module, which has at least a first type of cylindrical hollow body arranged at a distance from one another, which together with non-linear connecting struts span a frame. At least one further, second type of cylindrical hollow body is arranged within the stretched frame, with at least one cylindrical hollow body of the second type being connected to at least one cylindrical hollow body of the first type via at least one connecting web.Furthermore, the plastic grid multi-purpose module has at least one cylindrical hollow body of the third type, which is connected to the at least one cylindrical hollow body of the second type via at least one connecting web, wherein the at least one cylindrical hollow body of the third type has at least one recess and / or at least one through-opening in its outer surface and / or a base section, wherein all cylindrical hollow bodies have the same orientation. Finally, some of the cylindrical hollow bodies of the second type have at least one projection to which the at least one line guiding means can be coupled.

[0011] The advantage of the invention described here is that the special geometric design allows the provision of a highly stable plastic grid multi-purpose module. Several of these plastic grid multi-purpose modules can be coupled together to form a flat composite and laid on a wide variety of surfaces. For example, tire treads on heavy-duty trucks can be guided over the plastic grid multi-purpose module described here for the first time, even during tight turning maneuvers or small-wheel axle steering on a rear axle, without the tire tread becoming caught in the geometry of the plastic grid multi-purpose module and lifting, raising, or perhaps even displacing it from the composite. This makes it possible for the first time to provide a plastic grid multi-purpose module which can be laid in a flat composite and which can also be used permanently for driveways with heavy-duty traffic.At the same time, the proposed geometry has also proven advantageous for use in green roofs. Using the same geometry, but with a reduced material weight, it is possible to arrange flat, installable composites on roofs that are lightweight yet sufficiently stable. The additional at least one cable routing means allows at least one supply line to be provided.

[0012] A supply line is advantageously understood to mean a line that carries or can conduct electricity, data, and / or water. This also includes empty conduits.

[0013] Advantageous further training can be found in the subclaims.

[0014] The geometry of the plastic grid multi-purpose module described here for the first time advantageously has three differently cylindrical hollow bodies which, at least together with connecting webs and at least with connecting struts, form the flat plastic grid multi-purpose module.

[0015] It is advantageous to distinguish between at least three different types of cylindrical hollow bodies, since these are either geometrically different from one another and / or have different functions in the plastic grid multi-purpose module.

[0016] The plastic grid multi-purpose module is initially spanned by a frame which has a first type of cylindrical hollow body which is spaced apart from one another by connecting struts and at the same time connected to one another by the connecting struts. It has proven particularly advantageous if two cylindrical hollow bodies of the first type are permanently connected to one another by at least one connecting strut. In the simplest embodiment, a frame can thus be spanned in which cylindrical hollow bodies of the first type are arranged alternately and connecting to one another via connecting struts. A second type of cylindrical hollow body is provided within the spanned frame, which is advantageously of closed design. This second type of cylindrical hollow body is also arranged at a distance from one another.Advantageously, the fixation in the plastic grid multi-purpose module is achieved by connecting at least one cylindrical hollow body of the second type to at least one cylindrical hollow body of the first type via at least one connecting web. This advantageously ensures that the cylindrical hollow bodies of the second type are also fixed accordingly throughout the entire module and can be easily manufactured using the manufacturing process, for example, by injection molding.

[0017] Furthermore, the plastic grid multi-purpose module described here is characterized in that it further comprises at least one cylindrical hollow body of the third type. The at least one cylindrical hollow body of the third type can furthermore advantageously be connected to at least one cylindrical hollow body of the second type via at least one connecting web. The advantageous provision of connecting webs within the frame makes it possible to provide a particularly stable plastic grid multi-purpose module. Connecting webs and connecting struts are particularly advantageously designed with a different geometry to one another.

[0018] Furthermore, it has proven advantageous if the at least one cylindrical hollow body of the third type has at least one recess and / or at least one through-opening in its outer surface and / or a base section. Advantageously, through-opening is understood to mean a direct opening. Furthermore, recess is not an opening, but rather merely a modified shape of the geometry of the outer surface. For example, a recess can be understood to mean a depression, a bulge, or the like, at the position of which the outer surface continues to be continuous and closed.

[0019] Furthermore, it has proven to be particularly advantageous if all of the cylindrical hollow bodies of the first type, the second type and the third type have the same alignment. It is particularly advantageous if all of the cylindrical hollow bodies are arranged parallel to one another and spaced from one another by connecting struts and / or connecting webs. It has proven to be particularly advantageous if all of the cylindrical hollow bodies are aligned vertically and their first free end is open at the top. This is advantageous because it allows filling material to be poured into the open cylindrical hollow bodies, for example when laying floor surfaces, so that additional stability and driving safety can be created.In this context, it has also proven advantageous if the connecting struts and / or connecting webs are shorter and / or have the same vertical extension as the cylindrical hollow bodies. This can further improve stability and force dissipation.

[0020] Furthermore, the special geometric shape of the plastic grid multi-purpose module has proven to be advantageous, as it can compensate for thermal expansion of the material on hot days.

[0021] In a further advantageous embodiment, the at least one cable guide means has a coupling means on at least one free end, so that a positive connection and / or a non-positive connection is formed with the at least one projection in the use position. This coupling is advantageously reversible, so that it is also possible to separate the cable guide means from the plastic grid multi-purpose module again. This is advantageous because the at least one coupling means can form a secure and reliable connection between the cable guide means and the projection of the connecting struts. In one embodiment, the free ends of the cable guide means can be detachably coupled to the projections via a click connection. The at least one cable guide means is advantageously inserted from below.

[0022] The use position is advantageously understood to mean the position when the at least one line guide means has received a supply line and is coupled to it on at least one, advantageously on two mutually opposite projections, via a positive connection and / or frictional connection.

[0023] In a further advantageous embodiment, the coupling means can be designed as a projection. For this purpose, the coupling means is advantageously designed as a nose-like extension. The bevel provided here serves for easy insertion into the cylindrical hollow body of the second type. The horizontal line adjoining the bevel serves for fixation and is advantageously gripped by the projection in a use position. Thus, a detachable but very stable coupling can be achieved.

[0024] In a further advantageous embodiment, the at least one cable guide means is U-shaped. This is advantageous because the U-shaped curvature of the base allows at least one supply line to be accommodated securely and stably. Supply lines generally have a round cross-section, so that the base of the U-shaped cable guide means is also advantageously curved. In use, the base forms at least one common contact surface with the at least one supply line.

[0025] This is, of course, not to be understood as limiting; it is also conceivable for the base to have a flat profile, i.e., not be curved. This is the case, for example, if at least one rectangular cable duct is provided as the supply line. This, too, can be coupled with a plastic mesh multi-purpose module if appropriately designed.

[0026] In a further advantageous embodiment, two legs are designed to be increasingly spaced apart from one another as they extend towards a respective free end. One leg adjoins each end of the U-shaped base. Both legs extend in the same direction. In an advantageous embodiment, the distance between the legs changes. For example, the distance between the legs is greater at the free ends of the two legs than near the base. This is advantageous because it provides additional mobility of the legs. The coupling to the at least one projection of the cylindrical hollow body of the second type can thus be improved and carried out with reduced force application.

[0027] In a further advantageous embodiment, the two

[0028] Under the application of force, the legs are designed to be resilient at their free ends. This is advantageously made possible by the U-shaped design.

[0029] In a further advantageous embodiment, the cable guide is made of plastic. This is advantageous because it results in a particularly lightweight component. Furthermore, it can be easily manufactured, for example, by injection molding or 3D printing. The plastic also proves to be corrosion-resistant and durable. In the simplest case, polyolefins such as polyethylene and / or polypropylene can be selected for this purpose.

[0030] This is advantageous because it allows the cable guide to be given a resilient property. The two free ends then each have a nose-like extension on the legs. If a laterally acting compressive force is then exerted on the two free ends of the U-shaped cable guide, the two ends are brought towards one another. This makes it possible to feed the cable guide from below into the plastic grid multi-purpose module. More precisely, it is possible to guide the cable guide between two opposing projections of a cylindrical hollow body of the second type. If the compressive force is then removed, the restoring force causes the free ends to move away from one another again. This advantageously creates at least one positive connection and / or non-positive connection with the projections of the hollow body of the second type.Advantageously, the projections of the hollow body of the second type engage horizontally beneath the nose-like extensions of the free leg ends, thus creating a secure but reversible attachment. Subsequently, it is possible to pass at least one supply line through the thus created tab.

[0031] This is, of course, not to be understood as limiting, so that it is also conceivable that the at least one supply line is already partially inserted into the at least one line guide means before the reversible fastening thereof. The particularly advantageous provision of the projections of the cylindrical hollow body of the second type creates a high degree of individuality and flexibility, so that several supply lines can be reversibly arranged on the underside of the plastic multi-purpose module as required, thus forming a plastic multi-purpose system.

[0032] In a further advantageous embodiment, at least one connecting strut has at least one passage opening through which at least one supply line can be passed without being crushed. This is advantageous because at least one supply line can thus be arranged underneath a flatly laid plastic multi-purpose system without its function being impaired. The further passage openings can therefore advantageously also be understood as guides and / or receptacles for possible supply lines. Of course, it is not limited to irrigation lines, but can also be understood as any type of line, such as power lines or empty conduits which can later be filled with data cables or power cables. Furthermore, it has proven advantageous if the cylindrical hollow bodies of the second type also have passage openings.Another advantage is that they are arranged in alignment with the openings in the connecting struts. The additional openings in the connecting struts mean that cables, such as supply lines or empty conduits, can be laid at least partially underneath the cylindrical hollow bodies and are not crushed or damaged by the plastic grid multi-purpose modules when placed on the ground. The additional openings can therefore advantageously be understood as guides and / or receptacles for possible cables. Of course, this is not limited to irrigation lines, but can include any type of cable, such as power lines or empty conduits, which can later be filled with data cables or power cables.

[0033] In a further advantageous embodiment, the at least one passage opening of the connecting strut extends vertically from bottom to top. This is advantageous because it allows the possible lines and / or pipes to be arranged particularly easily in the corresponding passage openings without damaging the lines and / or pipes themselves. In the simplest case, these additional passage openings are U-shaped. This enables a precise arrangement of, for example, round irrigation lines or round empty conduits.

[0034] In a further advantageous embodiment, the vertical extent of the passage opening of the connecting strut is smaller than the vertical extent of the passage opening of the cylindrical hollow body of the first type. This is advantageous because the passage openings of the connecting struts are designed to accommodate cables and / or pipes. The passage openings in the lateral surfaces of the cylindrical hollow bodies of the first type, however, are necessary so that the coupling means of adjacent plastic grid multi-purpose modules can be at least partially inserted and the modules can be coupled to one another. Consequently, the passage openings differ in their technical functions.

[0035] In a further advantageous embodiment, the plastic grid multi-purpose module further comprises at least one supply line. In an advantageous embodiment, the at least one supply line is designed as a water pipe or drip hose. This is advantageous because it can provide irrigation and / or drainage. It has also proven particularly advantageous if the at least one supply line is designed to be at least partially or sectionally permeable to water. This makes it possible, on the one hand, to supply the floor area in which the plastic multi-purpose system is arranged with water. The low-lying arrangement of the at least one supply line on the underside of the plastic grid multi-purpose module prevents unnecessary evaporation of the supplied water in warm or hot environments.

[0036] Provided water can rise upwards toward the surface of the plastic multi-purpose system via capillary action. This ensures a constant level of basic humidity while simultaneously providing significant protection against evaporation.

[0037] This is of course not to be understood as limiting, so that the at least one supply line described here can also be designed for drainage. If, for example, the plastic multi-purpose system is arranged so that it is at least partially submerged in water due to heavy rain, standing water from at least one plastic grid multi-purpose module can be drained away directly via the at least one supply line and the openings provided at least in some sections. This can advantageously prevent damage to buildings or road surfaces from becoming soft when heavy goods vehicles are driving over it. It is also beneficial for plants as it prevents waterlogging. To drain away excess water, for example, at least one coupled pump can be made possible. This can advantageously suck water out of the at least one supply line at predetermined intensities and / or time intervals.

[0038] In a further advantageous embodiment, all of the cylindrical hollow bodies are of equal vertical length. This is advantageous because it creates a flat surface on both the top and bottom, ensuring high slip resistance and easy installation. In this first and simplest embodiment, it is also advantageous if the connecting struts and the connecting webs also have the same vertical length as all of the cylindrical hollow bodies. This creates a particularly stable and force-dissipating lattice structure that is flat on both its top and bottom.However, this is not to be understood as limiting, so that, depending on the use of the plastic grid multi-purpose module, the vertical extensions and / or the wall thicknesses of cylindrical hollow bodies, connecting struts and connecting webs can also differ.

[0039] In a further advantageous embodiment, the

[0040] Rectangular or square frames. The rectangular or square design has proven advantageous because the multi-purpose plastic grid modules can be installed particularly quickly and easily.

[0041] In another advantageous embodiment, the frame is rectangular or square. The rectangular or square design has proven advantageous because the plastic mesh multi-purpose modules can then be installed particularly quickly and easily.

[0042] If the frame is designed as a rectangle, it is conceivable that a cylindrical hollow body of the third type is also provided, centered in the middle. The articulation via the connecting webs takes place as already described for the square design. Furthermore, in the rectangular design of the frame, it is also conceivable that more than one cylindrical hollow body of the third type is provided. For example, it is conceivable that two, three or more of the cylindrical hollow bodies of the third type are arranged, advantageously along a straight line which runs through the center point.

[0043] In a further advantageous embodiment, the cylindrical hollow bodies are arranged vertically in the plastic grid multi-purpose module. This is advantageous because it provides cylindrical hollow bodies that are open at the top and can be filled, for example, with free-flowing bulk material. Free-flowing bulk material can be, for example, gravel, earth, sand or similar materials. This also allows the plastic grid multi-purpose module to be at least partially weighted down and filled in and / or on the corresponding subsurface. Advantageously, the cylindrical hollow bodies, regardless of their type, are open at the top when the plastic grid multi-purpose module is installed. This is to be understood as advantageous that they are openly accessible in the direction of the tread.In a further advantageous embodiment, four symmetrically arranged hollow bodies of the second type are arranged next to the at least one hollow body of the third type, which is particularly advantageously arranged centrally in the frame. Further advantageously, the at least one hollow body of the third type is each connected to a hollow body of the second type via a connecting web. In the case of the four hollow bodies of the second type provided here as an example, this means that four connecting webs branch off from the at least one hollow body of the third type and run to the hollow body of the second type. In the simplest case, the connecting webs extend outwards away from the hollow body of the third type. All four connecting webs converge at the center point or on a center line. It should be noted here that the convergence at the center point is advantageous in a square frame design.Furthermore, it should be taken into account that the convergence on a center line is advantageous in a rectangular frame design.

[0044] Of course, the four cylindrical hollow bodies of the second type are not to be understood as limiting, so that it is also conceivable for the at least one cylindrical hollow body of the third type to be surrounded by 6, 8 or even ten correspondingly symmetrically spaced cylindrical hollow bodies of the second type. Depending on the number of cylindrical hollow bodies of the second type, there is advantageously also at least the same number of connecting webs. In a further advantageous embodiment, the hollow bodies of the second type have a smaller outer diameter than the hollow bodies of the first type. This is advantageous because the hollow bodies of the second type are arranged inside the frame and are provided for additional stabilization and driving safety. It is therefore possible and practical to make their outer diameter smaller than the outer diameter of the hollow bodies of the first type.This allows for savings in material and overall weight. In contrast, the cylindrical hollow bodies of the first type advantageously have a larger outer diameter, as they are equipped with an additional function. This additional function consists in the fact that the cylindrical hollow bodies of the first type are designed for coupling several plastic grid multi-purpose modules together in a planar composite.

[0045] For this purpose, it has proven advantageous in a further advantageous embodiment if an outwardly extending coupling means is arranged on a jacket surface of at least one cylindrical hollow body of the first type and / or at least one passage opening is provided in a jacket surface of at least one cylindrical hollow body of the first type.

[0046] In a further advantageous embodiment, an outwardly extending coupling means is arranged on a lateral surface of at least one cylindrical hollow body of the first type, and / or at least one passage opening is provided in a lateral surface of at least one cylindrical hollow body of the first type. This is advantageous because it allows the surface assembly to be formed from several plastic grid multi-purpose modules that can be arranged next to one another. Individual plastic grid multi-purpose modules can be laid directly adjacent to one another using this locking mechanism.The at least one outwardly extending coupling means of a first plastic grid multi-purpose module and the correspondingly provided at least one lateral passage opening of a further plastic grid multi-purpose module arranged adjacent thereto make it possible to securely connect several plastic grid multi-purpose modules to one another, thus creating a surface composite. This is advantageous because it prevents an individual plastic grid multi-purpose module from tipping and allows a highly stable, durable surface composite shape to be provided. The lateral passage opening advantageously serves to at least partially accommodate the respective opposite coupling means.

[0047] A quick and easy production of the surface composite from several interconnected plastic grid multi-purpose modules is achieved by, for example, providing two plastic grid multi-purpose modules. Advantageously, both plastic grid multi-purpose modules have cylindrical hollow bodies of the first type with passage openings and cylindrical hollow bodies of the first type with coupling means. For example, it is conceivable for the provided plastic grid multi-purpose modules to have cylindrical hollow bodies of the first type with passage openings on two adjacent frame sides. Cylindrical hollow bodies of the first type with coupling means are then advantageously provided on the two remaining adjacent frame sides. The two plastic grid multi-purpose modules are now positioned in such a way that one frame side with passage openings faces a frame side with coupling means.The plastic grid multi-purpose module with the frame-side passage openings is then guided over the coupling means of the other plastic grid multi-purpose module and / or the coupling means are inserted into the passage openings from below and locked into place under force. The coupling means are then advantageously arranged at least in sections within the passage openings. It is particularly advantageous to place one coupling means in each passage opening at least in sections. This positive and / or non-positive connection creates a highly stable surface composite which is designed to be tilt-proof and slip-resistant. It is particularly advantageous here if the number of coupling means corresponds to the number of passage openings.

[0048] In a further advantageous embodiment, the at least one coupling means is hook-shaped. In the simplest embodiment, the hook shape can also be T-shaped. To form the corresponding surface connection, a T-shaped coupling means of a first plastic grid multi-purpose module can be introduced into a passage opening of a further plastic grid multi-purpose module arranged adjacent to it and connected to this in an advantageous locking position. For this purpose, both the T-shaped coupling means and advantageously the wall of the passage opening each have a corresponding projection which, after coupling, engage over and / or under one another and thus form a positive and / or non-positive connection.This prevents unwanted slipping out and dissolution of the surface connection, which can be formed by several plastic grid multi-purpose modules described here. In a further advantageous embodiment, the cylindrical hollow bodies of the first type and / or the cylindrical hollow bodies of the second type and / or the cylindrical hollow bodies of the third type are delimited on one side, at least in sections, by a base section. This is advantageous because the base section forms a lower boundary on the underside. This makes it possible for the plastic grid multi-purpose module to be easily arranged and leveled on the surface to be arranged.

[0049] Furthermore, the floor section serves to stabilize the plastic grid multi-purpose module against external forces, for example when driving over it with heavy goods vehicles.

[0050] To ensure rapid drainage, it has proven advantageous if the bottom section is not closed. It is particularly advantageous if the bottom section is provided with openings so that any accumulated water can be drained directly from the cylindrical hollow bodies into the surrounding soil.

[0051] For example, it is conceivable that in a first embodiment of the plastic grid multi-purpose module all cylindrical hollow bodies of the first and third type have, at least in sections, a molded-on base section. Advantageously, the base section is smaller than the inner diameter of the cylindrical hollow bodies, so that at least one, advantageously several, free spaces are created through which the water can be drained out of the cylindrical hollow bodies. Particularly advantageously, the base section of the cylindrical hollow bodies of the first type is geometrically different from the base section of the cylindrical hollow bodies of the second type and from the base section of the cylindrical hollow bodies of the third type. Furthermore, it is also conceivable that the base sections of the cylinders of the first type are also geometrically different from one another.This geometric design is advantageous when the plastic grid multi-purpose module is to be used as a heavy-duty grid plate.

[0052] In a further possible embodiment, it is again conceivable that only the cylindrical hollow bodies of the first and third type have a base section, at least in some sections. In this second embodiment, the cylindrical hollow bodies of the second type are designed without a base section. The cylindrical hollow bodies of the second type are completely open at the bottom; this embodiment is used when a low weight for the plastic grid multi-purpose module is desired. At the same time, the wall thicknesses of the plastic grid multi-purpose module in this second embodiment are smaller than in the first embodiment for heavy-duty use. The lightweight construction described here in this second embodiment can be advantageously used on roof surfaces.

[0053] In a further advantageous embodiment, it has proven advantageous if the cylindrical hollow body of the third type has at least one recess in its inward-facing outer surface. It has proven particularly advantageous if at least two or four such recesses are provided. The recesses are advantageous in that they enable particularly easy insertion of the connecting element. In the simplest case, the recesses are L-shaped and merge into L-shaped through-openings in the outer surface, so that the connecting element with complementary projections can be easily inserted and then locked into place by rotation. However, other shapes of the through-openings are also conceivable, for example elongated or slit-like. The outer surface then advantageously overlaps at least one projection of the connecting element, at least in section.This can be designed as a positive connection and / or a non-positive connection. If a connecting element is arranged in a cylindrical hollow body of the third type, its geometry is designed such that it is flush with the upper edge of the cylindrical hollow body. This advantageously also provides a flat tread surface.

[0054] A bayonet-type fastening is also possible. This ensures that the connecting element can always be easily removed. In the simplest case, the connecting element is also cylindrical and has corresponding projections on its outer surface that precisely fit the recesses and / or through-openings of the cylindrical hollow body of the third type, allowing for quick and easy insertion and rotation.

[0055] On its cover surface, which can advantageously be designed to be closed, the connecting element can have further openings, projections or the like, so that further geometric bodies can be arranged on the connecting element. This design is advantageous because it makes it possible for the first time to further develop a surface composite for floor areas and / or roof areas in such a way that additional objects, which can advantageously be detachably connected, can be connected to it. This creates a particularly high level of flexibility, so that the surface composite can, for example, be provided with additional signs, information panels, additional structures and the like. These can always be dismantled and reassembled at a different location if necessary.

[0056] In addition, the openings in the base section of the at least one cylindrical hollow body of the third type can also have a further function. For example, it has proven advantageous that the centrally arranged opening in the base section can also have a fixing function in addition to the drainage function. For example, it is possible to pass a ground spike or earth spike through this central opening via the cylindrical hollow body of the third type for long-term fixing under particularly high loads. The earth spike or earth spike advantageously has an enlarged material at its upper free end so that the base section can be spanned, at least in sections, and fixed accordingly to the subsurface. In the simplest case, the ground spike or earth spike is inserted by applying compressive force, for example by driving it into the subsurface.

[0057] To ensure sufficient adhesion to the ground, the plastic grid multi-purpose module filled with free-flowing material may be too light to be positioned securely on a surface without tipping or slipping. In this case, it is advisable to use at least one or more ground spikes or earth spikes to connect the floor sections of the plastic grid multi-purpose module to the ground. In the simplest case, ground spikes or earth spikes are driven or screwed through at least one central opening in a floor section. This method is reversible and can be removed again.

[0058] Of course, this is not to be understood as limiting. It is also conceivable that a ground spike or earth spike could be screwed into the ground, ensuring stable and permanent fixation of the plastic mesh multi-purpose module even under very heavy loads. This is particularly advantageous if only a single plastic mesh multi-purpose module is to be used. The ground spike or earth spike can provide secure ground fixation even when a plastic mesh multi-purpose module is used individually.

[0059] Furthermore, in a further advantageous embodiment, further openings can be provided in the base section of the cylindrical hollow body of the third type. For example, it is possible to provide at least one, advantageously two, further through-openings offset outwards relative to the central opening. These can also be smaller in diameter than the central opening. This at least one further through-opening in the base section is suitable for arranging a further component, for example in the form of a connecting element, which is provided for further fixing, for example, a rod, post, pipe or other geometric body which advantageously extends upwards in a vertical direction. For example, projections of the connecting element can be screwed or snapped into place through these through-openings.

[0060] This is also not limiting and should be understood as meaning that it is also conceivable for the geometric body, which advantageously extends upwards in the vertical direction, to have at least one or more projections at its lower free end, which projections can be inserted into the at least one, advantageously into the two further through-openings of the respective base section. This can provide further securing of the geometric body, which is advantageously inserted into the cylindrical hollow body, at least in sections.

[0061] In a further advantageous embodiment, the base section is connected to the outer surface of the cylindrical hollow bodies of the first and third type via base struts. This also further increases stability. Openings are advantageously provided between the base section and the base struts so that any accumulated water can be drained from the cylindrical hollow bodies.

[0062] In a further advantageous embodiment, imaginary extensions of the connecting struts converge and / or intersect at the center of each floor section. This has proven particularly advantageous because it ensures that the familiar truck tire treads do not interact with the geometry of the plastic grid multi-purpose module and hook into it. This permanently ensures that the plastic grid multi-purpose module can be used permanently and securely for driveways used by heavy-duty vehicles. Complex repair work on displaced or tilted components is no longer necessary. This can result in significant cost savings. The result is a highly stable heavy-duty plastic grid multi-purpose module.This can divert and distribute external forces, for example from the tires of a heavy-duty vehicle, particularly easily and quickly.

[0063] It should also be mentioned that the use with heavy-duty vehicles described here is of course not to be understood as limiting, but also includes any use of routes with trucks, for example fire service bypasses, shunting areas of industrial buildings, escape routes and the like. The heavy-duty plastic grid multi-purpose module can therefore be used to provide road surfaces for heavily used roadways in a permanent, reliable and safe manner. The special geometric design of the heavy-duty plastic grid multi-purpose module prevents it from being lifted out, lifted or moved. This ensures that the relevant roadway can always be used safely.

[0064] In a further advantageous embodiment, the outer surface of the hollow bodies of the second type has at least one passage opening which extends upwards from the underside and / or which extends downwards from the upper end of the hollow bodies towards the bottom section.

[0065] This embodiment is advantageous if at least one hollow body of the second type has at least one further upwardly extending passage opening. These passage openings are advantageous if, for example, lines and / or pipes are to be laid beneath the plastic grid multi-purpose module. In order to prevent the pipes and / or lines from becoming crushed, it has proven advantageous if the plastic grid multi-purpose module has, at least in sections, cutouts through which the pipes and / or lines can be passed. This saves a lot of space and the pipes and / or lines are held securely and protected from being crushed. These cutouts are implemented by the passage openings described here in the cylindrical hollow bodies of the second type.It is particularly advantageous if two passage openings of a cylindrical hollow body of the second type are always arranged in alignment with one another.

[0066] In a further advantageous embodiment, the connecting struts are curved inwards. This has proven to be advantageous because this design ensures particularly high stability against external forces. Twisting or breaking of the plastic grid multi-purpose module is thus ruled out. It has proven particularly advantageous if the individual connecting struts are each curved inwards. This is advantageous because, when laid in a flat composite, additional spaces are created between two adjacent plastic grid multi-purpose modules, which can be quickly and easily filled with free-flowing material. If the connecting struts were curved outwards, the connecting struts of plastic grid multi-purpose modules laid in a flat composite would butt against one another and thus create predetermined breaking points.

[0067] In the simplest case, it is conceivable that the connecting struts are continuously curved, i.e., bent. This is not to be understood as limiting, however; it is also conceivable that the connecting struts are flattened at their maximum curvature. Geometrically, this would then result in a widened U-shape.

[0068] The variants of the plastic grid multi-purpose module described here can advantageously be manufactured in different weights. The material weights are advantageously based on the intended use. For example, if an installation assembly with plastic grid multi-purpose modules is to be laid in fire service access routes, the requirements for this are as a heavy-duty plastic grid multi-purpose module. Consequently, the modules will have a higher material weight and thicker walls than if they were installed on the roof. In this case, lightweight plastic grid multi-purpose modules would be used, which are lighter and have thinner walls. Furthermore, the plastic grid multi-purpose modules described here can also have different heights.

[0069] Different heights are necessary, for example, if the terrain has a stepped shape or if lateral step boundaries are required when laying the tiles.

[0070] Furthermore, the present invention relates to a planar installation assembly with at least two plastic multi-purpose systems which are connected to one another via coupling means and passage openings.

[0071] Furthermore, the present invention also relates to the use of a plastic grid multi-purpose system as a modular component of a flat composite, in use as a floor covering for driveways with heavy load use or particularly stressed driveways such as shunting areas of industrial buildings or commercial properties, as a modular component of a flat composite for roof areas, as a modular component of a flat composite in roof greening, as a modular component of a flat composite in the floor area, as a modular component of a flat composite for the irrigation of equestrian facilities, riding halls, riding arenas, livestock stables both indoors and outdoors.

[0072] The flat composite consisting of a large number of plastic multi-purpose systems is particularly advantageous. The plastic grid multi-purpose modules used for this purpose are connected to one another by the coupling mechanism described above. Due to the special geometry of the plastic grid multi-purpose module, it can also be used in escape routes, parking lots, roadways with high and heavy loads or even in fire service access routes. The special geometry between the connecting struts and / or connecting webs and the cylindrical hollow bodies prevents the individual plastic grid multi-purpose modules, which can also be referred to as modules, from being levered up or shifted out of the flat composite when heavy-duty vehicles drive over them and / or perform turning maneuvers on them.By having at least one pipe routing system, these driveways can also be irrigated underground and will no longer silt up in hot temperatures.

[0073] The same applies to the use of the lightweight construction on roof surfaces. Here, too, permanently greened surfaces can be provided. Furthermore, in a further embodiment of the plastic grid multi-purpose module, this can be designed with an additional irrigation function. This is advantageous because the at least one supply line, which can be laid without crushing through the openings in the connecting struts and / or through the openings in the connecting webs, allows green roofs that are particularly susceptible to drought to be supplied with sufficient moisture quickly and easily. Here, too, it is advantageous that the at least one supply line does not run directly on the tread surface, but rather at a depth of 4-35 cm.

[0074] Particularly advantageous for this purpose is at least one plastic grid multi-purpose module, more advantageously several plastic grid multi-purpose modules, coupled together as a flat composite, each having at least one cable routing means, at least partially filled with soil or other filling material and / or covered with soil or other filling material to a depth of 5-25 cm. This provides sufficient soil material for planting and for additional fastening. This allows moisture to be provided from below, which can spread upwards via capillary action. This makes it possible to water green roofs indirectly, so that they remain attractively green even in summer or in particularly dry regions, without too much water being wasted through direct irrigation. At the same time, it is possible to provide a substrate with a predeterminable moisture content.This can also prevent cracks and hardening of the soil. It has proven particularly advantageous if the soil moisture is recorded by at least one sensor and the irrigation intensity is regulated accordingly by at least one control unit. At the same time, the plastic multi-purpose system described here makes it possible to drain standing water on roofs in the event of heavy rainfall. This can be done, for example, using at least one additionally connectable pump which actively pumps out the standing water via the laid pipes once a pre-determined water level is reached. For this purpose, too, at least one sensor which records the water level can advantageously be provided.

[0075] Furthermore, the plastic multi-purpose system described here can also be used as a single foundation for posts, preferably made of wood or plastic, fence posts, preferably made of wood or plastic, sign poles, preferably made of wood or plastic, and / or roof structures made of metal or the like. This also provides an additional use. This can be used, for example, when sunlight is to be used to generate electricity using suitable modules, and these must be attached to roofs.

[0076] It is also conceivable that plastic multi-purpose systems could be used in a wider range of areas. It has proven particularly advantageous to use the plastic multi-purpose system as a surface-mounted assembly for the irrigation and / or drainage of equestrian facilities, riding arenas, riding halls or riding arenas, both indoors and outdoors. In equestrian sports in particular, it has been common practice to moisten riding facilities using the so-called "ebb and flow" method. This involves flooding sand arenas, for example, with water to prevent dust from forming on hot, dry days. At the same time, this watering makes the sand firmer, giving the horses a sure footing and making riding easier on the horses' joints. This method is disadvantageous in that it constantly uses up a lot of water and does not provide a permanently, evenly moist surface.With the modular plastic grid multi-purpose module described here, which can optionally be supplemented with at least one water pipe and which can be laid as a flat composite, it is possible to provide a constant, permanent soil moisture.

[0077] When used for this purpose, it has proven advantageous if the plastic grid multi-purpose module is laid in the ground, for example at a depth of 4-15 cm. It is advantageous to fill in sand directly above the plastic grid multi-purpose module to create a sand footing for the horses. If watering is carried out from below via several, optionally interconnected plastic grid multi-purpose systems, preferably with several water supply lines, it is possible to keep the sand footing permanently moist from below in order to provide the best possible training surface for the horses. It is also particularly advantageous here that the soil moisture can be recorded by at least one sensor and regulated by at least one control unit.Furthermore, it has proven particularly advantageous to install the flat-laying plastic grid multi-purpose module described here directly in the ground without any additional tools. No further protection of the supply lines is necessary, as these are already incorporated into the underside of the plastic grid multi-purpose modules and are thus secured by the cable routing means. It is therefore possible to lay the plastic grid multi-purpose system described here in a flat composite, with the supply lines already pre-assembled. During final assembly, the supply lines are then connected to one another to create a closed pipe network. Irrigation can also be additionally supported by at least one pump, which is particularly advantageous.It has proven particularly advantageous if the plastic mesh multi-purpose module is made at least partially, preferably entirely, from plastic, even more preferably from thermoplastic. Examples of this are advantageous olefins, such as polypropylene and / or polyethylene.

[0078] The plastic used can, for example, be unprocessed, recycled, fiber-reinforced, filled in some other way, for example with nanoparticles, biodegradable, and / or mixtures and / or combinations thereof. In the simplest case, acrylonitrile butadiene styrene, polyamide, polyethylene, or polypropylene are used.

[0079] To achieve sufficient stabilization of the plastic grid multi-purpose module described here once installed, it has proven advantageous to fill the resulting chamber-like structures with free-flowing material. In the simplest case, this could be soil, for example. It is also conceivable to use other free-flowing materials, such as stones, sand, gravel, or mixtures thereof.

[0080] Further advantages, features and design options emerge from the following description of non-limiting embodiments.

Furthermore, components that are not essential to understanding the technical teaching disclosed herein are not shown or described. In the following, the reference symbols will not be repeated for all elements already introduced and illustrated, provided that the elements themselves and their function have already been described or are known to a person skilled in the art.

[0096] Detailed description of working examples

[0097] Figure 1 shows a first embodiment of the plastic grid multi-purpose module 100 in a top view. It shows a total of eight cylindrical hollow bodies 102 of the first type, which are at least partially bounded at the bottom by a bottom section 104. The bottom sections 104 are, as shown, discontinuous, so that, for example, waterlogging can be drained directly into the surrounding soil.

[0098] The cylindrical hollow bodies 102 of the first type are connected to one another via inwardly curved connecting struts 106. The cylindrical hollow bodies 102 of the first type, together with the connecting struts 106, form the frame R. The frame R represents the boundary of the plastic grid multi-purpose module 100. Furthermore, the hollow bodies 102 of the first type are not all of the same design, but may differ in the base section 104 and / or in the design of the lateral surfaces.

[0099] Within this tensioned frame R, further cylindrical hollow bodies 108 of the second type are arranged. These cylindrical hollow bodies 108 of the second type are in turn firmly and permanently connected to the cylindrical hollow bodies 102 of the first type via connecting webs 110, which are advantageously shorter than the connecting struts 106. In this exemplary embodiment, a cylindrical hollow body 108 of the second type is connected to three cylindrical hollow bodies 102 of the first type via a total of three connecting struts 110, i.e. with one connecting strut 110 per connection. Finally, a cylindrical hollow body of the third type 112 is provided centered in the middle.

[0100] Overall, the plastic grid multi-purpose module 100 thus has a square basic shape. This square basic shape is advantageous in all versions of the plastic grid multi-purpose module.

[0101] Furthermore, it is shown that the cylindrical hollow bodies 102 of the first type can have both outwardly projecting coupling means 114 and passage openings 116. Cylindrical hollow bodies 102 of the first type are also shown which can have only one coupling means 114, only one passage opening 116, or even two passage openings 116. This is advantageous because it allows several plastic grid multi-purpose modules 100 to be connected to one another to form a laying assembly. The different arrangement of coupling means 114 and passage openings 116 makes it possible to create a stable laying assembly.

[0102] Particularly advantageously, the laterally projecting coupling means 114 are T-shaped. In order to be able to form a planar laying connection, the base sections 104 in the area of ​​the passage openings 116 also have a T-shaped head geometry. This is advantageous because the T-shaped coupling means 114 can be inserted into this geometry and can also be locked therein via projections 115. Furthermore, the base sections 104 can have different sizes

[0103] Have openings, for example, in a round shape. This is advantageous because it allows for targeted water drainage and prevents waterlogging.

[0104] It can also be seen that the cylindrical hollow bodies of the second type 108 have a smaller outer diameter than the cylindrical hollow bodies of the first type 102. It can also be seen that the cylindrical hollow bodies of the second type 108 do not have a delimiting base section 104. They are designed without a base section. The cylindrical hollow bodies of the second type 108, on the other hand, have a plurality of passage openings 118, which are each additionally delimited by an advantageously continuous projection 120. These passage openings 118 are advantageous in that they allow lines, pipes or the like (not shown) to be guided through underneath the plastic grid multi-purpose module 100 without being crushed. The passage openings 118 of the cylindrical hollow bodies of the second type 108 are particularly advantageously arranged in alignment with one another.

[0105] Furthermore, it is also advantageous if at least some of the connecting struts 106 also have at least one further passage opening (not shown here), which can also be arranged in alignment with the passage openings 118. In this way, lines, pipes and the like can be laid in a particularly simple and quick manner without them being crushed or damaged in any other way. At the same time, an irrigation system can then also advantageously be provided. Particularly advantageously, the provided passage openings are designed to be congruent with the passage openings 118, so that arranging and laying lines, pipes and the like can be carried out particularly simply and quickly.

[0106] In this exemplary embodiment, the centrally arranged cylindrical hollow body of the third type 112 has four internal recesses 122. These recesses are designed as guide grooves into which a connecting element (not shown here), also referred to as an adapter, can be inserted and rotated in. In order to enable this rotating in in the sense of a bayonet mechanism, the base section 104 and / or the outer surface of the cylindrical hollow body of the third type advantageously has four through openings 124. These can advantageously be elongated or L-shaped. It is possible to insert projections of the connecting element (not shown) into these through openings 124 and to fix them by rotation at least in sections below the outer surface and / or that of the base section 104.

[0107] Finally, the surfaces of connecting struts 106, connecting webs 110, and the cylindrical hollow bodies 102, 108, 112 are at least partially covered with projections 126, which in the simplest case can be hemispherical. The projections 126 serve to provide slip resistance and additional grip to the surfaces, for example, when it is raining and wet or when they are transported stacked. Furthermore, these projections 126 also serve as a positioning aid for attachments, so that they can be arranged quickly and securely in a slip-proof manner on the plastic grid multi-purpose module 100, 200, 300.

[0108] Figure 2 shows a side view of the plastic grid

[0109] Multi-purpose module 100 from Figure 1. Here it can firstly be seen that the clamped frame R is uniformly designed on the upper side and has a flat surface from which only the projections 126 protrude upwards. The T-shaped coupling means 114 is shown protruding laterally on the right-hand side. This connects to a cylindrical hollow body of the first type 102. The side view shown here shows the passage openings 116 through which the installation connection can later be formed by a T-shaped coupling means 114 of a further plastic grid multi-purpose module 100 being introduced at least in section through this passage opening 116 and locked into place.

[0110] In addition to the passage openings 116 in the cylindrical hollow bodies of the first type 102, further passage openings 128 are shown, which are arranged in the connecting struts 106. Both the passage openings 116 and the further passage openings 128 extend from the underside in a vertical direction upwards and are advantageously rounded at their ends. The further passage openings 128 of the connecting struts 106 are lower in their vertical extent than the passage openings 116. This is due to the fact that the further passage openings 128 are provided for cable routing, whereas the passage openings 116 have the corresponding vertical extent, as also shown by the T-shaped coupling means 114. Only then is it possible for the coupling means 114 to be arranged completely and safely in the passage openings 116.This is particularly important because the resulting installation assembly is also flat on its underside so that it can be leveled accordingly. Figure 3 shows a perspective view of the plastic grid multi-purpose module 100 from Figure 1. Here it is particularly clearly shown that the connecting struts 106 are curved inwards. At the same time, both the passage openings 128 and the further passage openings 116 are shown. Furthermore, it can be seen that locking projections 115 are provided on the inner surface of the passage openings 116, which latching projections interact with the coupling means 114 to be introduced and advantageously form a positive connection and / or a non-positive connection.

[0111] Furthermore, it is evident that the connecting webs 110 are short and run in a straight line. Also visible in this perspective view are the recesses 122 in the inner surface of the cylindrical hollow body of the third type 112. These can be understood in the simplest case as guide grooves. The recesses 122 cause an outward bulge. This allows material to be saved, since the entire hollow body 122 does not have to be formed with a thicker wall to provide the recesses 122.

[0112] The embodiment of the plastic mesh multi-purpose module 100 shown in Figures 1-3 is used in the heavy-duty sector and can therefore also be referred to as a heavy-duty plastic mesh multi-purpose module 100. For this purpose, it has particularly thick walls. The walls can be single-piece or double-walled.

[0113] Figure 4 shows a further top view of another plastic grid multi-purpose module 200. The embodiment shown here differs visually from the embodiment shown in Figure 1 in that the walls of the entire plastic grid multi-purpose module 200 are significantly thinner and narrower. This means that the plastic grid multi-purpose module 200 shown here can be advantageously used in lightweight construction. The wall reduction allows material and thus weight to be saved. The embodiment shown here can also advantageously be referred to as a lightweight plastic grid multi-purpose module 200.

[0114] Shown here are a total of eight cylindrical hollow bodies 202 of the first type, which are at least partially delimited at the bottom by a bottom section 204. The bottom sections 204 are, as shown, discontinuous, so that, for example, waterlogging can be drained directly into the surrounding soil.

[0115] The cylindrical hollow bodies 202 of the first type are connected to one another via inwardly curved connecting struts 206. The cylindrical hollow bodies 202 of the first type, together with the connecting struts 206, form the frame R. The frame R represents the boundary of the lightweight plastic lattice multi-purpose module 200.

[0116] Within this tensioned frame R, further cylindrical hollow bodies 208 of the second type are arranged. These cylindrical hollow bodies 208 of the second type are in turn firmly and permanently connected to the cylindrical hollow bodies 202 of the first type via connecting webs 210. In this exemplary embodiment, a cylindrical hollow body 208 of the second type is connected to three cylindrical hollow bodies 202 of the first type by a total of three connecting struts 210, i.e. one connecting web 210 per connection. Finally, a cylindrical hollow body of the third type 212 is provided centered in the middle. Overall, a square basic shape of the lightweight plastic grid multi-purpose module 200 is thus tensioned.

[0117] Furthermore, it is shown that the cylindrical hollow bodies of the first type 202 can have both outwardly projecting coupling means 214 and passage openings 216. Cylindrical hollow bodies 202 are also shown which can have only one coupling means 214, only one passage opening 216, or even two passage openings 216. This is advantageous because it allows several plastic grid multi-purpose modules 200 to be connected to one another to form a laying assembly. The different arrangement of coupling means 214 and passage openings 216 can produce a stable, planar laying assembly.

[0118] Particularly advantageously, the laterally projecting coupling means 214 are T-shaped. In order to form a planar installation connection, the base sections 204 also have a T-shaped head geometry in the area of ​​the passage openings 216. This is advantageous because the T-shaped coupling means 214 can be inserted into this geometry and also locked therein via projections 215.

[0119] Furthermore, the base sections 204 can have openings of different sizes, for example, in a round shape. This is advantageous because it allows for additional targeted drainage of water and prevents waterlogging.

[0120] Furthermore, it can be seen that the cylindrical hollow bodies of the second type 208 are smaller in their outer diameter than the cylindrical hollow bodies of the first type 202.

[0121] Furthermore, it can be seen that the cylindrical hollow bodies of the second type 208 do not have a delimiting base section 204. The cylindrical hollow bodies of the second type 208, on the other hand, have a plurality of passage openings 218, which are each additionally delimited by an advantageously continuous projection 220. These passage openings 218 are advantageous in that they allow lines, pipes or the like (not shown) to be guided through below the plastic grid multi-purpose module 200 without being crushed. The passage openings 218 of the cylindrical hollow bodies of the second type 208 are particularly advantageously arranged in alignment with one another.

[0122] Furthermore, it is also advantageous if at least some of the connecting struts 206 also have at least one further passage opening (not shown here), which is also arranged in alignment with the passage openings 218. In this way, lines, pipes and the like can be laid in a particularly simple and quick manner without them being crushed or otherwise damaged. At the same time, an irrigation system can then also advantageously be provided. Particularly advantageously, the provided passage openings are designed to be congruent with the passage openings 218, so that arranging and laying lines, pipes and the like can be carried out particularly simply and quickly.

[0123] The centrally arranged cylindrical hollow body of the third type 212 has, in this exemplary embodiment, a base section 204. This advantageously has four through-openings 224. These can advantageously be elongated or L-shaped. Projections of the connecting element (not shown) can be inserted into these through-openings 224 and fixed by rotation at least in sections below the jacket surface (not shown here) and / or below a projection 225 and / or below the base section 204. This fixing is advantageously carried out by means of a bayonet mechanism. It is advantageous if, for this purpose, inwardly directed projections 225 are provided on the inner surfaces of the jacket, which projections can be provided for additional holding.

[0124] Finally, the surfaces of connecting struts 206, connecting webs 210, and the cylindrical hollow bodies 202, 208, 212 are at least partially covered with projections 226, which in the simplest case can be hemispherical. The projections 226 serve to provide anti-slip properties and additional grip to the surfaces, for example, when it is raining and wet or when they are transported stacked. Furthermore, these projections 226 also serve as a positioning aid for attachment devices, so that they can be arranged quickly and securely in a non-slip manner on the plastic grid multi-purpose module 100, 200, 300.

[0125] Figure 5 shows a side view of the plastic grid multi-purpose module 200 from Figure 4. Here, it can firstly be seen that the stretched frame R is uniformly formed on the upper side and forms a flat surface from which only the projections 226 protrude upwards. The T-shaped coupling means 214 is shown protruding laterally on the right-hand side. This connects to a cylindrical hollow body of the first type 202. The side view shown here shows the passage openings 216 through which the installation connection can later be formed by a T-shaped coupling means 214 of a further plastic grid multi-purpose module 200 being introduced at least in section through this passage opening 216 and locked into place.

[0126] In addition to the passage openings 216 in the cylindrical hollow bodies of the first type 202, further passage openings 228 are shown, which are arranged in the connecting struts 206. Both the passage openings 216 and the further passage openings 228 extend from the underside in a vertical direction upwards and are advantageously rounded at their ends. The further passage openings 228 of the connecting struts 206 are lower in their vertical extent than the passage openings 216. This is due to the fact that the further passage openings 228 are provided for cable routing, whereas the passage openings 216 have the corresponding vertical extent, as also shown by the T-shaped coupling means 214. Only then is it possible for the coupling means 214 to be arranged completely and safely in the passage openings 216.This is particularly important because the resulting installation composite is also flat on its underside so that it can be levelled accordingly.

[0127] Figure 6 shows a perspective view of the plastic grid multi-purpose module 200 from Figure 4. It is particularly clearly shown here that connecting struts 206 are curved inward. At the same time, both the additional passage openings 228 and the passage openings 216 are shown. Furthermore, it can be seen that locking projections 215 are provided on the inner surface of the passage openings 216, which interact with the coupling means 214 to be introduced and advantageously form a positive and / or non-positive connection.

[0128] Furthermore, it can be seen that the connecting webs 210 are short and run in a straight line.

[0129] Also shown in this perspective view is the cylindrical hollow body of the third type 212, which is designed differently from the cylindrical hollow body 112 of Figure 3. The reduction in material results in thinner walls overall. For this lightweight plastic grid multi-purpose module 200, this means that the cylindrical hollow body of the third type 212 has no outwardly directed recesses.

[0130] The embodiment of the plastic grid multipurpose module 200 shown in Figures 4-6 is used in lightweight construction and can therefore also be referred to as a lightweight plastic grid multipurpose module 200. For this purpose, it has particularly thin walls. The walls can be single-piece or double-walled.

[0131] Figure 7 shows the bottom view of the plastic grid multi-purpose module 100 from Figure 1. The same reference numerals refer to the same components and will not be explained again here. The passage openings 128 of the connecting struts 106 are shown on the bottom side shown. These are arranged in alignment with the passage openings 118. In the simplest exemplary embodiment, the passage openings 118, 128 have the same geometry. The plastic grid multi-purpose module 100 also has a cable guide 4. This is U-shaped and coupled to the projections (not shown) of the cylindrical hollow body of the second type 108. In this embodiment, the coupling is effected via a click mechanism, so that the free ends (not shown) of the cable guide are gripped under by the projections (not shown) and thus fixed. The cable guide means 4 holds a supply line 16 at least in sections.As can be seen, it is essential that the through-holes 118, 128 are aligned with each other. Only in this way is it possible to quickly and easily click the supply line 16 into place via the cable guide on the underside of the plastic mesh multi-purpose module. A plastic multi-purpose system 1 with a supply line 16 is formed.

[0132] Figure 8 shows a further bottom view of a plastic mesh multi-purpose module 200 from Figure 4. The same reference numerals refer to the same components and will not be explained again. The through-openings 228 of the connecting struts 206 are shown on the illustrated underside. These are arranged in alignment with the through-openings 218. In the simplest embodiment, the through-openings 218, 228 are of identical geometry. Furthermore, the plastic mesh multi-purpose module 200 has a cable guide 4. This is U-shaped and coupled to the projections (not shown) of the cylindrical hollow body of the second type 208. In this embodiment, the coupling is achieved via a click mechanism, so that the free ends (not shown) of the cable guide are gripped by the projections (not shown) and thus fixed. The cable guide 4 holds a supply line 16, at least in sections.As can be seen, it is essential that the through-openings 218, 228 are aligned with each other. Only in this way is it possible to quickly and easily click the supply line 16 into place via the cable guide on the underside of the plastic mesh multi-purpose module. A plastic multi-purpose system 2 with a supply line 16 is formed.

[0133] Figure 9 shows another enlarged view of Figure 7, which can also be transferred to Figure 8.

[0134] Figure 10 shows another sectional view from Figure 9. The cylindrical hollow body of the second type 108, 208 is shown here in vertical section. The cylindrical hollow body of the second type 108, 208 is open at the top. In its lower region, the projections 120, 220 are arranged, which extend horizontally into the free internal volume of the cylindrical hollow body of the second type 108, 208. The passage openings 118, 218 are provided below the projections 108, 208. Advantageously, each cylindrical hollow body of the second type 108, 208 has four passage openings 118, 218 and thus also four projections 120, 220. These are arranged opposite one another in pairs.

[0135] The line guiding means 5 is U-shaped here. It has a curved base 8. This base advantageously forms a common contact surface, at least in sections, with the supply line 16 that can be arranged therein. The supply line 16 rests on the base 8 and is held by the latter. Starting from the curved base 8, two legs 10, 12 extend upwards. Both legs each have a free end 14, which is also designed as a coupling means 6. Furthermore, it is shown that the legs diverge in the direction of their free ends. The U-shape widens. This widening is advantageous because it allows the legs 10, 12 and in particular the coupling means 6 to be given a resilient property. The coupling means 6 are designed as nose-like extensions.On the one hand, they have a bevel directed diagonally downwards, which then merges into a horizontal border. The bevel is advantageous for the easy introduction of the two coupling means 6 from below into the cylindrical hollow body of the second type 108, 208. The coupling means 6 are subjected to force by the introduction and slide particularly easily past the projections 118, 218 due to the bevel. Here, an additional force can again act on the coupling means 6. The legs 10, 12 are moved towards one another. When the projections 118, 218 are passed over, the legs 10, 12 are reset, so that the coupling means 6 are guided outwards. At this point they are already gripped by the projections 118, 218 and are held in the click position. Thus, an easily implemented, detachable fixing of the supply line 16 can be provided.

[0136] To remove the cable guide means 4, the legs 10, 12 are again subjected to a force, advantageously a compressive force, so that the nose-like extensions 6 are guided away from the projections 120, 220 and, in the compressed state, are removed downwards from the cylindrical hollow body of the second type 108, 208.
