Description

[0001] Plastic grid multi-purpose module for the formation of a flat installation connection for floor and / or roof surfaces and its use

[0002] Description

[0003] The present invention relates to a plastic grid multi-purpose module for forming a planar composite, which is particularly suitable for heavy goods traffic and / or for arrangement on roof surfaces, but also for other uses.

[0004] background

[0005] Concrete floor reinforcements are known from practice, in particular for keeping fire brigade access routes or other escape routes permanently accessible. However, such floor reinforcements have proven to be disadvantageous because they are very heavy when laid. Furthermore, the known concrete floor reinforcements have proven to be disadvantageous because permanent interlocking of the individual roadway reinforcement elements with one another is not possible. In practice, it is therefore often observed that the floor reinforcement elements settle or tip over sideways, particularly in emergency access routes. Safe driving, especially when, for example, injured people have to be transported, can therefore no longer be guaranteed. There is also an increasing demand for roof surfaces to be greened. This also requires modules that can be arranged flexibly and have a particularly low dead weight due to the roof load limitations.

[0006] Task

[0007] Therefore, the object of the present invention is to provide a multi-purpose plastic grid module that can be used for secure and permanent ground reinforcement for traffic routes with heavy loads, ambulances, fire service access routes, or other escape routes. Furthermore, the object of the present invention is to be particularly cost-effective to manufacture. Furthermore, the object of the present invention is to have a significantly reduced dead weight, particularly compared to the concrete fastening elements or roof surface elements known from the prior art, so that the present invention can also be used in green roofs.

[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 grid multi-purpose module for forming a planar installation assembly for floor surfaces and / or roof surfaces. This comprises at least a first type of spaced apart, cylindrical hollow bodies which, together with non-linear connecting struts, span a frame, wherein at least one further, second type of cylindrical hollow bodies is arranged within the stretched frame and at least one cylindrical hollow body of the second type is connected to at least one cylindrical hollow body of the first type via at least one connecting web. Furthermore, the

[0011] Plastic grid multi-purpose module at least one centrally arranged cylindrical hollow body of the third type, which is connected via at least one connecting web to the at least one cylindrical hollow body of the second type, 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 in a base section and wherein all cylindrical hollow bodies have the same orientation.

[0012] 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 laid as a flat composite 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 hooking into the geometry of the plastic grid multi-purpose module and lifting it out of the composite, or perhaps even shifting it. This makes it possible for the first time to provide a plastic grid multi-purpose module which can be laid as a flat composite and which can also be used permanently for driveways with heavy loads.At the same time, the proposed geometry has also proven advantageous for use in green roofs. Using the same geometry, but with simply a reduced material weight, it is possible to arrange composites that can be laid flat on roofs and are lightweight yet sufficiently stable. It has also proven particularly advantageous that the plastic grid multi-purpose module described here is made of plastic, so that it itself has a low dead weight. This can save labor, especially during the installation process. Furthermore, production, for example using injection molding, is cost-effective and can be reproduced quickly.

[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, 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 connecting webs also have the same vertical length as all of the cylindrical hollow bodies. This creates a particularly stable and force-dissipating grid structure that is flat on both its top and bottom. Depending on the application of the plastic grid multi-purpose module, the vertical lengths and / or the wall thicknesses of the cylindrical hollow bodies, connecting struts and connecting webs can vary.

[0022] 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.

[0023] If, for example, the frame is square, the cylindrical hollow body of the third type is arranged centrally in this frame. Starting from the cylindrical hollow body of the third type, connecting webs extend to cylindrical hollow bodies of the second type. Starting from the cylindrical hollow bodies of the second type, further connecting webs extend to the cylindrical hollow bodies of the first type. In this way, a lattice structure is formed.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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 cylindrical hollow bodies of the second type, which are spaced symmetrically therefrom. Depending on the number of cylindrical hollow bodies of the second type, at least the same number of connecting webs is advantageously present.

[0028] 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 can save material and overall weight. In contrast, the cylindrical hollow bodies of the first type advantageously have a larger outer diameter because they are equipped with an additional function. This additional function consists in the cylindrical hollow bodies of the first type being provided for coupling several plastic grid multi-purpose modules to one another in a planar composite.

[0029] 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.

[0030] 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 composite to be formed from a plurality of plastic grid multi-purpose modules that can be arranged next to one another.

[0031] Individual plastic grid multi-purpose modules can be laid directly next 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 to it make it possible to connect several plastic grid multi-purpose modules to one another in a displacement-proof manner, thus creating a surface composite. This is advantageous because it prevents an individual plastic grid multi-purpose module from tipping over and can provide a highly stable, durable surface composite shape. The lateral passage opening advantageously serves to at least partially accommodate the respective opposite coupling means.

[0032] 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.

[0033] 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 composite, which can be formed by several plastic grid multi-purpose modules described here.

[0034] In a further advantageous embodiment, at least one connecting strut has at least one further opening. This is additionally advantageous because it allows for the passage of cables. This is relevant, for example, when irrigation lines are to be laid under the plastic grid multi-purpose module described here and / or the plastic grid multi-purpose module surface composite.

[0035] The additional openings in the connecting struts allow cables, such as supply lines or empty conduits, to be laid at least partially beneath the cylindrical hollow bodies and, when placed on the ground, to avoid being crushed or damaged by the plastic grid multi-purpose modules. The additional openings can therefore also be advantageously understood as guides and / or receptacles for possible cables. Of course, this is not limited to irrigation lines; it can also be understood as any type of cable, such as power lines or empty conduits, which can later be filled with data cables or power cables.

[0036] 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.

[0037] 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.

[0038] 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 installed.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] In a third possible embodiment of the plastic grid multi-purpose module, however, it is also conceivable for the base section to be almost completely closed and for only the cylindrical hollow body of the third type and, at least in sections, the cylindrical hollow bodies of the first type to have base section openings in the area of ​​the passage openings. This means that the base section is continuous in the remaining areas. Both the cylindrical hollow bodies of the second type and the free areas, which are bordered by connecting struts and connecting webs, also have a closed base section. The almost completely closed base section makes it possible to specifically keep rainwater in the plastic grid multi-purpose module and to prevent it from flowing out of the plastic grid multi-purpose module too quickly. This way, a retention function can be provided.This is particularly advantageous when the plastic grid multi-purpose modules are laid in a flat assembly, used on roof surfaces and planted. This retention function, which can also be understood as a water retention function, makes it possible to allow plants that are planted, for example, directly in the cylindrical hollow bodies that are open at the top and / or the corresponding spaces between connecting struts, hollow bodies or connecting webs, to be watered for longer during the drying period. By providing the additional retention function, a plastic grid multi-purpose module designed in this way can also be referred to as a retention plastic grid multi-purpose module. In addition, additional stability is gained by additionally closing the base section.It should be noted here that the base section is not completely closed but that excess water can flow out of the multi-purpose plastic retention grid module via at least one opening in the base section. In the simplest case, the wall area of ​​at least one hollow cylinder of the first type is designed with a passage opening for coupling with further multi-purpose plastic retention grid modules. This passage opening is separated from the internal volume of the cylindrical hollow body, for example with a suitable wall. Advantageously, the wall is in a tight fit with the base section. The height of the wall can be freely determined and depends on how high the water should be in the multi-purpose plastic retention grid module before it can flow over the edge of the wall.Advantageously, the area of ​​the outer surface of the hollow cylinder of the first type, separated by the wall, is open at the bottom, allowing water to flow out of the multi-purpose plastic grid retention module. The wall serves as an overflow and prevents permanently stagnant water, which can also promote root rot.

[0044] This also allows planted attachments with a water retention function to be supplied with additional water. The attachments can advantageously be inserted via their base elements into the upwardly open cylindrical hollow bodies of the first type and held securely therein. This makes it possible to provide the plastic grid multi-purpose modules for supplying water to attachments, into which the plants can then advantageously be planted. It is possible to use these attachments in retention plastic grid multi-purpose modules and / or in plastic grid multi-purpose modules with an irrigation function and / or in plastic grid multi-purpose modules of the simplest design. At the same time, the retention plastic grid multi-purpose module variants described here can also always be installed in combination with one another.

[0045] In a third embodiment, the remaining base section openings can also be closed in a targeted manner. This can be achieved, for example, by the locking mechanism, as already described above. Furthermore, it is conceivable that the base section opening in the at least one cylindrical hollow body of the third type can be closed by at least one connecting element, which can advantageously also be referred to as an adapter, which has at least one rib structure.

[0046] The at least one connecting element particularly advantageously serves to form a connection between the plastic grid multi-purpose module and a geometric body which can advantageously be arranged vertically for this purpose. Such a body can be, for example, a pipe, a post, a holding device or the like. It is also conceivable for the geometric body to have the connecting element directly formed thereon. In the simplest case, the at least one connecting element can be understood as an adapter. For particularly high stability in the installation assembly, it is therefore advantageous if the at least one connecting element is coupled into the cylindrical hollow body of the third type. This is advantageously arranged centrally in the plastic grid multi-purpose module.

[0047] 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.

[0048] 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.

[0049] 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 surfaces and / or roof surfaces in such a way that additional objects, advantageously detachable ones, can be connected to it. This creates a particularly high level of flexibility, so that the surface composite can, for example, be additionally provided with signage, information panels, additional structures and the like.

[0050] These can always be dismantled and rebuilt at a different location if necessary.

[0051] 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.

[0052] In order to ensure sufficient adhesion to the ground, the plastic grid multi-purpose module filled with free-flowing material may not be lightweight enough to be positioned 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 hammered or screwed through at least one central opening in a floor section. This method is reversible and can be removed again. This is of course not to be seen as limiting; it is also conceivable that ground spikes or earth spikes can be screwed into the ground, thus ensuring stable and permanent fixing of the plastic grid 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 be used to provide secure ground fixation even when a single plastic mesh multi-purpose module is used.

[0053] In addition, in another advantageous

[0054] In this embodiment, further openings can be provided in the base section of the cylindrical hollow body of the third type. For example, it is possible for at least one, advantageously two, further through-openings to be provided 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 vertically upwards. For example, projections of the connecting element can be screwed or snapped into place through these through-openings.

[0055] 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.

[0056] 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.

[0057] 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, as 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 financial savings.

[0058] This creates a highly stable, heavy-duty, multi-purpose plastic mesh module. This module can easily and quickly dissipate and distribute external forces, such as those from the tires of a heavy-duty vehicle.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] If, however, in a third exemplary embodiment the water storage is the focus, the cylindrical hollow bodies of the second type and / or the cylindrical hollow bodies of the first type can have further passage openings. These are aligned downwards towards the base section, starting from the free, upward-facing end of the respective hollow body. This can advantageously prevent water from being stored in a closed cylindrical hollow body of the first and / or second type, whereas the other, adjacent cylindrical hollow bodies are dry or have a water shortage. The openings extending from top to bottom can ensure a uniform water exchange. Advantageously, however, these passage openings do not penetrate the closed base, so that water storage is also ensured.

[0063] In this way, a retention plastic grid multi-purpose module can be formed which has a closed, and therefore advantageously watertight, base. This creates a trough in which water can be held and stored. In a further advantageous embodiment, the base can be at least partially curved inwards. In the simplest case, this can be achieved, for example, using arched extensions. This is advantageous if at least one supply line still has to be laid beneath the plastic grid multi-purpose module. For example, it may be necessary to lay power lines, data lines or even water lines. Due to the closed shape of the base of the above-mentioned plastic grid multi-purpose module with retention function, it is not possible for the at least one supply line to be passed directly through the cylindrical hollow body.In order to be able to provide this quickly and easily, the retention plastic grid multi-purpose module can have at least one passage opening in at least one connecting strut. This passage opening is advantageously arranged at least partially vertically offset from the closed floor. But in any case is tightly spanned by it. In this exemplary embodiment, too, the passage opening can be curved. This is the simplest geometry for supply lines such as empty conduits to be led through. This geometry advantageously continues in the floor. Consequently, the watertight, closed floor is curved inwards at least in sections. This allows the optionally inserted supply lines to be positioned in the curve at least in sections and held in the desired position.To this end, the supply lines can be selected depending on the shape of the curve to ensure adequate protection. However, this is not to be understood as a limitation; it is also conceivable that supply lines with smaller diameters can be quickly and easily routed through the lower section of the multi-purpose plastic grid retention module. This can also be done retrospectively. The "floor" is advantageously understood to mean the area consisting of several floor sections. Another advantage is that the floor is designed to be watertight.

[0064] 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.

[0065] 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.

[0066] 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 combination 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. However, it is possible to couple the different variants of the retention plastic grid multi-purpose modules with one another and form an installation combination.Different heights are necessary, for example, if the terrain has a stepped shape or if lateral step boundaries are required when laying the tiles.

[0067] In a further advantageous embodiment, imaginary extensions of the connecting struts converge and / or intersect at the center of each floor section. This is advantageous because it can increase stability.

[0068] Furthermore, the present invention relates to a planar installation assembly with at least two plastic grid multi-purpose modules, which are connected to one another via coupling means and passage openings.

[0069] Furthermore, the present invention also relates to the use of a plastic grid multi-purpose module as a modular component of a planar 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 planar composite for roof surfaces, as a retention component for irrigation.

[0070] Furthermore, the use described here also includes at least use as a floor covering for driveways with heavy loads or driveways subject to particularly high levels of wear, such as shunting areas in industrial buildings or commercial properties. The flat composite of a large number of plastic grid multi-purpose modules laid over a large area is particularly advantageous. The plastic grid multi-purpose modules 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 subject to high and heavy loads, or even in fire service access routes.

[0071] The special geometry between connecting struts and / or connecting webs and cylindrical hollow bodies prevents the individual plastic grid multi-purpose modules, which can also be referred to as modules, from being levered up and shifted out of the flatly laid assembly when heavy-duty vehicles drive over them and / or perform turning maneuvers on them.

[0072] This is, of course, not intended to be limiting; it is also conceivable that the plastic grid multi-purpose modules described here could be used as retention panels, also known as retention plastic grid multi-purpose modules, on the ground and / or on roofs. This is advantageous because it allows green roofs to be supplied with water even during dry periods.

[0073] Furthermore, in a further embodiment of the plastic grid multi-purpose module, it can be designed with an additional irrigation function. This is advantageous because, via 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, green roofs that are particularly susceptible to drought can be supplied with sufficient moisture quickly and easily. Here, too, it is advantageous that the at least one supply line does not run directly along the tread surface, but rather at a depth of 4-35 cm. A supply line can be understood, for example, as a water pipe, an electrical line, or even a conduit.

[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, at least partially filled with soil or other filling material and / or covered with soil or other filling material to a depth of 4-25 cm. This provides sufficient soil material for planting and for additional stabilization. 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 subsoil with a predetermined moisture content. This also prevents cracks in the soil and hardening of the soil.It has proven particularly advantageous in this regard if soil moisture is detected by at least one sensor and the irrigation intensity is regulated accordingly by at least one control unit. At the same time, the plastic grid multi-purpose module described here makes it possible to drain standing water on roofs in the event of heavy rain. This can be achieved, for example, additionally via at least one connectable pump, which actively pumps the standing water out via the installed pipes once a predeterminable water level is reached. For this purpose, too, at least one sensor can advantageously be provided to detect the water level.

[0075] Furthermore, the plastic grid multi-purpose module 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.

[0076] It is also conceivable to use plastic grid multi-purpose modules in a wider area. It has proven particularly advantageous to use plastic grid multi-purpose modules as a surface-laying composite 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 formation 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 has proven 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 10-20 cm. It is advantageous to add sand directly above the plastic grid multi-purpose module to create a sand footing for the horses. If water is then provided from below via several, optionally interconnected plastic grid multi-purpose modules, preferably with several water supply lines, it is possible to keep the sand footing permanently moist in order to provide the best possible training surface for the horses. It is 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 aids.No additional protection of the supply lines is necessary, as they are already integrated into the underside of the plastic mesh multi-purpose modules and thus secured. It is therefore possible to install the plastic mesh multi-purpose module described here in a flat assembly, with the supply lines already pre-assembled. During final assembly, the supply lines are then connected to each other, creating a closed network. Irrigation can also be advantageously supported by at least one pump.

[0078] It has proven particularly advantageous if the plastic mesh multi-purpose module is made at least partially, preferably entirely, from thermoplastic material. Examples of this are advantageous olefins, such as polypropylene and / or polyethylene.

[0079] 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.

[0080] 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.

[0081] Further advantages, features and design options emerge from the following description of non-limiting embodiments.

[0097] Detailed description of working examples

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] Particularly advantageously, the laterally projecting coupling means 114 are T-shaped. In order to form a planar installation connection, the base sections 104 also have a T-shaped head geometry in the area of ​​the passage openings 116. This is advantageous because the T-shaped coupling means 114 can be inserted into this geometry and also locked therein via projections 115.

[0104] Furthermore, the base sections 104 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.

[0105] 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.

[0106] 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.

[0107] 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.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 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 forms 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.

[0109] 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 composite is also flat on its underside so that it can be levelled accordingly.

[0110] Figure 3 shows a perspective view of the plastic mesh multi-purpose module 100 from Figure 1. It is particularly clearly shown here that the connecting struts 106 are curved inward. At the same time, both the passage openings 128 and the additional 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 interact with the coupling means 114 to be introduced and advantageously form a positive and / or 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.

[0117] Overall, a square basic shape of the lightweight plastic grid multi-purpose module 200 is created.

[0118] 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.

[0119] Particularly advantageous are the laterally protruding

[0120] Coupling means 214 is 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] Furthermore, it can be seen that the connecting webs 210 are short and run in a straight line.

[0131] 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.

[0132] The embodiment of the

[0133] The 200 plastic mesh multi-purpose module is used in lightweight construction and can therefore also be referred to as the 200 lightweight plastic mesh multi-purpose module. It features particularly thin walls. The walls can be single-piece or double-walled.

[0134] Figure 7 shows a further advantageous embodiment of the plastic grid multi-purpose module 300. The embodiment of the plastic grid multi-purpose module 300 shown here in plan view has a retention function. This advantageously means that the module 300 shown here is designed for water storage. The embodiment shown here differs from the two previously described embodiments in that it has a nearly closed base section 304. The plastic grid multi-purpose module 300 shown here can therefore also be referred to as a plastic grid tray multi-purpose module 300 or retention plastic grid multi-purpose module 300.

[0135] The embodiment shown here differs visually from the embodiment shown in Figure 1 in that the walls are significantly thinner and narrower. This means that the plastic mesh multi-purpose module 300 shown here can be advantageously used in lightweight construction. The embodiment shown here can also be advantageously referred to as a lightweight retention plastic mesh multi-purpose module 300.

[0136] A total of eight cylindrical hollow bodies 302 of the first type are shown here, which are largely delimited on the base side by a single base section 304, which can also be referred to as the base as a whole. The base section 304 is, as shown, only interrupted in the coupling areas of the passage openings 316, so that the T-shaped coupling means 314 of adjacent modules (not shown) can also be safely and reliably inserted and fixed. Advantageously, the interruptions have the corresponding, precisely fitting shape to the coupling means head 314. Finally, a further opening 332 can also be provided, which is arranged centrally in the cylindrical hollow body of the third type 312. This is advantageous if the plastic grid multi-purpose module 300 has to be additionally anchored in the ground using ground hooks or other fastening means (not shown here).This is the case, for example, if further structures follow and their wind load has to be taken into account. Alternatively, this opening 332 can simply be omitted, resulting in a floor section 304 that is closed except for the L-shaped through openings 324. The cylindrical hollow body of the third type 312 has, as in the previous exemplary embodiment 212, no further through openings extending vertically from top to bottom in the shell surface. Thus, for the water storage in the entire plastic grid multi-purpose module 300, it is irrelevant whether the third hollow body 312 is closed or partially open through the through openings 324, 332. The vertical extension of the hollow body of the third type 312 is flush with the other hollow bodies 302, 308 in terms of its surface.

[0137] In all other floor areas, floor section 304 is designed to be continuous. Continuous means closed, so that no water can escape and / or enter.

[0138] The cylindrical hollow bodies 302 of the first type are connected to one another via inwardly curved connecting struts 306. The cylindrical hollow bodies 302 of the first type, together with the connecting struts 306, form the frame R. The frame R represents the boundary of the plastic grid multi-purpose module 300.

[0139] Within this tensioned frame R, further cylindrical hollow bodies 308 of the second type are arranged. These cylindrical hollow bodies 308 of the second type are in turn firmly and permanently connected to the cylindrical hollow bodies 302 of the first type via connecting webs 310. In this exemplary embodiment, a cylindrical hollow body 308 of the second type is connected to three cylindrical hollow bodies 302 of the first type by a total of three connecting struts 310, i.e. one connecting web 310 per connection. Finally, a cylindrical hollow body of the third type 312 is provided centered in the middle.

[0140] Overall, a square basic shape of the plastic grid multi-purpose module 300 is created.

[0141] Furthermore, it is shown that the cylindrical hollow bodies of the first type 302 can have both outwardly projecting coupling means 314 and passage openings 316. Cylindrical hollow bodies 302 are also shown which can have only one coupling means 314, only one passage opening 316, or even two passage openings 316. This is advantageous because it allows several plastic grid multi-purpose modules 300 to be connected to one another to form a laying assembly. The different arrangement of coupling means 314 and passage openings 316 can produce a stable laying assembly.

[0142] The laterally projecting coupling means 314 are particularly advantageously T-shaped. In order to be able to form a planar laying connection, the base section 304 also has a T-shaped head geometry in the region of the passage openings 316. This is advantageous because the T-shaped coupling means 314 can be inserted into this geometry and can also be locked therein via projections (not shown). The base section 304 is therefore offset in the region of the passage openings 316 so that the coupling means 314 can be locked via the passage openings 316 and precisely do not collide with the base section 304.

[0143] Furthermore, it can be seen that the cylindrical hollow bodies of the second type 308 are smaller in their outer diameter than the cylindrical hollow bodies of the first type 302.

[0144] In this exemplary embodiment, the centrally arranged cylindrical hollow body of the third type 312 has an adapted base section 304a. This advantageously has four through-openings 324. These can advantageously be elongated or L-shaped. Projections of the connecting element (not shown) can be inserted into these through-openings 324 and fixed by rotation at least in sections below the jacket surface (not shown here) and / or below at least one projection 325 and / or below the base section 304. This fixing is advantageously carried out by means of a bayonet mechanism. It is advantageous if inwardly directed projections 325 are provided on the jacket inner surfaces for this purpose, which projections can be provided for additional holding.

[0145] Finally, the surfaces of connecting struts 306, connecting webs 310, and the cylindrical hollow bodies 302, 308, 312 are at least partially covered with projections 326, which in the simplest case can be hemispherical. The projections 326 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 326 also serve as a positioning aid for attachment devices, so that they can be arranged quickly and securely in a slip-proof manner on the plastic grid multi-purpose module 100, 200, 300.

[0146] Figure 8 shows a side view of the plastic grid multi-purpose module 300 from Figure 7. 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 326 protrude upwards. The T-shaped coupling means 314 is shown protruding laterally on the right-hand side. This connects to a cylindrical hollow body of the first type 302. The side view shown here shows the passage openings 316 through which the installation connection can later be formed by a T-shaped coupling means 314 of a further plastic grid multi-purpose module 300 being introduced at least in section through this passage opening 316 and locked into place.

[0147] Apart from the passage openings 316 in the cylindrical hollow bodies of the first type 302, no further passage openings are provided. The connecting struts 306 are closed. Only the passage openings 316 extend from the underside in a vertical direction upwards and are advantageously rounded at their ends. A cable routing is not provided in this exemplary embodiment. Figure 9 shows a perspective view of the plastic grid multi-purpose module 300 from Figure 7. Here it is particularly clearly shown that the connecting struts 306 are curved inwards. The passage openings 316 are also shown.

[0148] Furthermore, it can be seen that locking projections 330 are provided on the inner surface of the passage openings 316, which interact with the coupling means 314 to be introduced and advantageously form a positive connection and / or a non-positive connection.

[0149] Furthermore, it can be seen that the connecting webs 310 are short and run in a straight line. This perspective view also shows the cylindrical hollow body of the third type 312, which is different from the cylindrical hollow body 112 of Figure 3, but identical to the cylindrical hollow body 212 of Figure 6. The reduction in material results in thinner walls overall. For this plastic grid multi-purpose module 300 of Figure 9, this means that the cylindrical hollow body of the third type 312 has no outward-facing recesses.

[0150] Finally, this perspective view also shows that both the cylindrical hollow bodies of the first type 302 and the cylindrical hollow bodies of the second type 308 have openings 334 in their outer surfaces that extend vertically downwards. These openings 334 are advantageously U-shaped. These openings 334 advantageously serve to distribute incoming water, for example in the event of rain, evenly throughout the entire frame R. This prevents, for example, water from accumulating in a single cylindrical hollow body 302. The water can always flow away evenly through the openings 334 and be evenly distributed overall within the frame R. The water can be held accordingly and thus stored at the same time by the closed base section 304. These openings 334 advantageously do not penetrate the base section 304.Only the hollow body of the third type 312 is exempt from this. It does not have such flow openings 334.

[0151] In addition, there are wall boundaries in at least one cylindrical hollow body of the first type 302. This is shown as a section in Figure 10. The cylindrical hollow body of the first type 302 shown here has a coupling means 314 and at the same time also a passage opening 316. Connection to further hollow bodies, not shown, is made via the connecting struts 306 and the connecting web 310. This section shows, on an enlarged scale, that the base section 304 is almost completely closed. Since, as already described above, several plastic grid multi-purpose modules are coupled together to form a laying assembly, the retention function also requires areas in the base section 304 where coupling means from further plastic grid multi-purpose modules can be introduced from below through the passage opening 316. A cavity 336 is formed behind the passage opening 316.Its geometric extension conforms to the coupling means (not shown here). To prevent unwanted water leakage, the cavity 36 is vertically and laterally delimited by a wall section 338. This results in a widened C-shape.

[0152] The cavity 336 is therefore still open towards the bottom. This results in an opening in the base section 304. However, the wall section 338 ensures that the water is held in the frame and does not flow out again directly via the opening in the base section 304. It is particularly advantageous for the wall section 338 to be of different heights in its vertical extension upwards. This is advantageous because the wall section 338 also serves as an overflow and excess water can drain out of the frame via this. This is the case when the wall section 338 only delimits the cavity laterally and vertically, and the cavity is also open at the top and bottom.

[0153] The embodiment of the plastic grid multi-purpose module 300 shown in Figures 7 to 10 is used in lightweight construction as a retention plate and can therefore also be referred to as a lightweight plastic grid retention plate module 300. For this purpose, it has particularly thin walls and a largely closed base section 304. The walls can be formed as one piece or as double walls.

[0154] Figure 11 shows a further advantageous embodiment of the plastic grid multi-purpose module 400. This corresponds to the plastic grid multi-purpose module 300 from Figure 7, wherein in the embodiment shown here, the base section 404 is curved inward in regions 405.

[0155] The embodiment of the plastic grid multi-purpose module 400 shown here in plan view has a retention function. This advantageously means that the module 400 shown here is designed for water storage. The embodiment shown here differs from the two previously described embodiments in that it has a nearly closed bottom section 404. The plastic grid multi-purpose module 400 shown here can therefore also be used as a plastic grid tray multi-purpose module

[0156] 400 or retention plastic grid multi-purpose module 400.

[0157] The embodiment shown here differs visually from the embodiment shown in Figure 1 in that the walls are significantly thinner and narrower. This means that the plastic mesh multi-purpose module 400 shown here can be advantageously used in lightweight construction. The embodiment shown here can also be advantageously referred to as a lightweight retention plastic mesh multi-purpose module 400.

[0158] Here, a total of eight cylindrical hollow bodies 402 of the first type are shown, which are largely delimited on the bottom side by a single bottom section 404, which can also be referred to as the bottom. As shown, the bottom section 404 is interrupted only in the coupling regions of the passage openings 416, so that the T-shaped coupling means 414 of adjacent modules (not shown) can also be safely and reliably inserted and fixed.

[0159] Advantageously, the interruptions have a corresponding, precisely fitting shape to the coupling means 414. Finally, a further opening 432 can also be provided, which is arranged centrally in the cylindrical hollow body of the third type 412. This is advantageous if the plastic grid multi-purpose module 400 has to be additionally anchored in the ground using ground hooks or other fastening means (not shown here). This is the case, for example, if further structures follow and their wind load has to be taken into account. Alternatively, this opening 432 can simply be omitted, resulting in a closed base section 404 except for the L-shaped through openings 424. The cylindrical hollow body of the third type 412 has, as in the previous exemplary embodiment 212 from Figure 4, no further through openings extending vertically from top to bottom in the shell surface.Thus, for the water storage in the entire plastic grid multi-purpose module 400, it is irrelevant whether the third hollow body 412 is closed or partially open through the through openings 424, 432. The vertical extension of the hollow body of the third type 412 is flush with the surface of the other hollow bodies 402, 408.

[0160] In all other floor areas, floor section 404 is designed to be continuous. Continuous means closed, so that no water can escape and / or enter.

[0161] The cylindrical hollow bodies 402 of the first type are connected to one another via inwardly curved connecting struts 406. The cylindrical hollow bodies 402 of the first type, together with the connecting struts 406, form the frame R. The frame R represents the boundary of the plastic grid multi-purpose module 400.

[0162] Within this tensioned frame R, further cylindrical hollow bodies 408 of the second type are arranged. These cylindrical hollow bodies 408 of the second type are in turn firmly and permanently connected to the cylindrical hollow bodies 402 of the first type via connecting webs 410. In this exemplary embodiment, a cylindrical hollow body 408 of the second type is connected to three cylindrical hollow bodies 402 of the first type by a total of three connecting struts 410, i.e. one connecting web 410 per connection. Finally, a cylindrical hollow body of the third type 412 is provided centered in the middle.

[0163] Overall, a square basic shape of the plastic grid multi-purpose module 400 is created.

[0164] Furthermore, it is shown that the cylindrical hollow bodies of the first type 402 can have both outwardly projecting coupling means 414 and passage openings 416. Cylindrical hollow bodies 402 are also shown which can have at least one coupling means 414, only one passage opening 416, or even two passage openings 416. This is advantageous because it allows several plastic grid multi-purpose modules 400 to be connected to one another to form a laying assembly. The different arrangement of coupling means 314 and passage openings 416 can produce a stable laying assembly.

[0165] The laterally projecting coupling means 414 are particularly advantageously T-shaped. In order to be able to form a planar laying connection, the base section 404 also has a T-shaped head geometry in the region of the passage openings 416. This is advantageous because the T-shaped coupling means 414 can be inserted into this geometry and can also be locked therein via projections (not shown). The base section 404 is therefore offset in the region of the passage openings 416 so that the coupling means 414 can be locked via the passage openings 416 and precisely do not collide with the base section 404.

[0166] Furthermore, it can be seen that the cylindrical hollow bodies of the second type 408 are smaller in their outer diameter than the cylindrical hollow bodies of the first type 402.

[0167] In this exemplary embodiment, the centrally arranged cylindrical hollow body of the third type 412 has an adapted base section 404a. This advantageously has four through-openings 324. These can advantageously be elongated or L-shaped. Projections of the connecting element (not shown) can be inserted into these through-openings 424 and fixed by rotation at least in sections below the jacket surface (not shown here) and / or below at least one projection 425 and / or below the base section 404. This fixing is advantageously carried out by means of a bayonet mechanism. It is advantageous if inwardly directed projections 425 are provided on the jacket inner surfaces for this purpose, which projections can be provided for additional holding.

[0168] Finally, the surfaces of connecting struts 406, connecting webs 410, and the cylindrical hollow bodies 402, 408, 412 are at least partially covered with projections 426, which in the simplest case can be hemispherical. The projections 426 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 426 also serve as a positioning aid for attachment devices, so that they can be arranged quickly and securely in a slip-proof manner on the plastic grid multi-purpose module 100, 200, 300, 400.

[0169] Figure 12 shows a side view of the plastic grid

[0170] Multi-purpose module 400 from Figure 11. Here it can firstly be seen that the stretched frame R is uniformly designed on the upper side and forms a flat surface from which only the projections 426 protrude upwards. A T-shaped coupling means 414, for example, is shown protruding laterally on the right-hand side. This connects to a cylindrical hollow body of the first type 402. In the side view shown here, passage openings 428 are also shown, through which at least one supply line (not shown) can later be led. These passage openings 428 are arranged in the lower region of the connecting struts 306. They advantageously have an arc shape.This is advantageous since the at least one supply line advantageously also has an arcuate or round cross-section, so that easy and quick insertion and passage through the plastic grid multi-purpose module 400 can be provided.

[0171] Figure 13 shows a perspective view of the plastic mesh multi-purpose module 400 from Figure 11. This particularly clearly shows that the connecting struts 406 are curved inward. At the same time, the passage openings 428 in the lower region of the connecting struts 406 are shown.

[0172] Furthermore, it can be seen that locking projections 430 are provided on the inner surface of the passage openings 416, which can interact with the coupling means 414 to be introduced and then advantageously form a positive connection and / or a non-positive connection.

[0173] Furthermore, it can be seen that the connecting webs 410 are short and straight. This perspective view also shows the cylindrical hollow body of the third type 412. The reduction in material results in thinner walls overall. For this plastic grid multi-purpose module 400, this means that the cylindrical hollow body of the third type 412 has no outward-facing recesses.

[0174] Finally, this perspective view also shows that both the cylindrical hollow bodies of the first type 402 and the cylindrical hollow bodies of the second type 408 have openings 434 in their outer surfaces that extend vertically downwards. These openings 434 are advantageously U-shaped. These openings 434 advantageously serve to distribute incoming water, for example in the event of rain, evenly throughout the entire frame R. This prevents, for example, water from accumulating in a single cylindrical hollow body 402. The water can always flow away evenly through the openings 434 and be evenly distributed overall within the frame R. The water can be held accordingly and thus stored at the same time by the closed base section 404. These openings 434 advantageously do not penetrate the base section 404.

[0175] Only the hollow body of the third type 412 is exempt from this. It does not have such flow openings 434. Furthermore, there are wall boundaries in at least one cylindrical hollow body of the first type 402. Reference is made here to Figure 10, which also applies to this embodiment.

[0176] The floor section 404 is here, with the exceptions listed above, closed, i.e. watertight. Since it is nevertheless desirable, if necessary, to lay supply lines (not shown) below the plastic grid multi-purpose module 400, in this exemplary embodiment the laying option is laid vertically downwards, below the closed floor section 404. Advantageously, several passage openings 428 are provided, which can also cross below the floor section 404. Advantageously, a tunnel system is formed. Thus, at least one supply line can be pulled in and laid below the floor section 404 at a later date in a simple and quick manner. For this purpose, the floor section 404 is curved inwards in regions 450.

[0177] In this exemplary embodiment, optional eyelets 440 are also provided. These can be used for additional fastening of the plastic mesh multi-purpose module 400 to a support, such as roof battens, in the ground, or the like. In the simplest case, this fastening is achieved by means of screws.

[0178] Figure 14 shows the plastic grid multi-purpose system 400 again. This time in a bottom view. In this bottom view, the hollow bodies of the second type 408 are not shown separately. It can be seen that the floor section 404, with the above-mentioned exceptions, is closed. Below the floor section 404, a tunnel extension 442 can be seen, through which the at least one supply line (not shown) can be laid. Tunnel intersections are also shown. This provides a high degree of flexibility for subsequently required supply lines.

[0179] The embodiment of the plastic grid multi-purpose module 400 shown in Figures 11 to 14 is used in lightweight construction as a retention plate and can therefore also be referred to as a lightweight plastic grid retention plate module 400. For this purpose, it has particularly thin walls and a largely closed base section 404. The walls can be designed as one piece or as double walls. Although the invention has been illustrated and described in more detail by the advantageous exemplary embodiments, the invention is not limited by the disclosed examples. Other variations can be derived therefrom by a person skilled in the art without departing from the scope of the invention. In particular, the invention is not limited to the combinations of features specified below, but other combinations and partial combinations that are obvious to a person skilled in the art can also be formed from the disclosed features.
