Description

[0001] The present invention relates to a plastic multi-purpose irrigation system and its use. State of the art

[0002] Multi-purpose plastic components are known from the state of the art, which can be installed as a flat composite for ground reinforcement or as a foothold for animals. Such multi-purpose plastic components often prove disadvantageous in practice, as plant growth in the open spaces of the multi-purpose plastic components is virtually impossible, especially during hot, dry periods. Task

[0003] Therefore, the object of the present invention is to provide a plastic multi-purpose system for irrigation and / or drainage that can be used for a variety of purposes. Furthermore, the object of the present invention is to provide a plastic multi-purpose system for irrigation and / or drainage that can be used continuously, even under heavy traffic. Furthermore, the object of the present invention is to provide a plastic multi-purpose system for irrigation and / or drainage that can be manufactured cost-effectively. Furthermore, the object of the present invention is to enable reliable and permanent water control for roofs and floors. Solution

[0004] The problem is solved by the technical features specified in patent claim 1.

[0005] The core idea of ​​the present invention is to provide a plastic multi-purpose system for forming a planar composite with at least one cable routing means and at least one plastic multi-purpose component which has at least one repeating unit. Particularly advantageously, the at least one repeating unit has two cylindrical hollow bodies arranged at a distance from one another and non-linearly extending connecting struts connecting these hollow bodies, so that a chamber-like structure is present. In order to further form a particularly stable plastic multi-purpose component, the connecting struts of a repeating unit and / or the connecting struts of two repeating units connected to one another thereby have a symmetrical curvature and, moreover, the connecting struts are arranged opposite one another.

[0006] Furthermore, a portion of the connecting struts has at least one projection, to which the at least one cable guide means can be coupled in sections. This is advantageous because it allows at least one or more supply lines to be flexibly and individually coupled to the plastic multi-purpose component via at least one cable guide means. This provides a particularly high degree of variability, so that the plastic multi-purpose system described here, laid in a planar composite, can be used in many different applications.

[0007] A further advantage of the invention described here is that the special geometric design allows for the provision of a highly stable, flatly deployable composite, which is composed of a plurality of the modular plastic multi-purpose systems described here and coupled together. The additional at least one cable guide means allows for the provision of at least one supply line.

[0008] Advantageously, a supply line is understood to be a line that can carry or conduct electricity, data and / or water.

[0009] It has also proven particularly advantageous that the plastic multi-purpose component described here is made of plastic, resulting in a low weight. This allows for labor savings, particularly during installation. Furthermore, production, for example, using injection molding, is cost-effective and quickly reproducible.

[0010] The geometry of the plastic multipurpose system, or more advantageously the plastic multipurpose component, described here for the first time, advantageously has at least one repeating unit. Of course, this is not to be understood as limiting, so it is also conceivable for a plastic multipurpose system to have several repeating units, which are then connected to each other with individual connecting struts.

[0011] Particularly advantageously, a repeating unit is formed by two cylindrical hollow bodies, which are permanently connected by two connecting struts that are advantageously spaced apart from one another but symmetrically curved. Advantageously, the connecting struts are not formed as straight longitudinal and / or transverse struts, but rather have a curved shape.

[0012] Furthermore, the curvatures of two connecting struts of a repeating unit are symmetrical to each other. This is, of course, not to be understood as limiting, so it is also conceivable that the connecting struts may have additional recesses, projections, or the like. This does not in itself affect the symmetrical curvature disclosed here.

[0013] A plastic multi-purpose system disclosed here for the first time can advantageously have several such repeating units.

[0014] Furthermore, the special geometric shape of the multi-purpose plastic component has proven to be advantageous, as it can compensate for thermal expansion of the material on hot days.

[0015] Advantageous further training can be found in the subclaims.

[0016] In a further advantageous embodiment, the at least one cable guide has a coupling element at each free end, so that a positive and / or non-positive connection is formed with the at least one projection. This is advantageous because the at least one coupling element allows a secure and reliable connection to be formed between the cable guide and the projection of the connecting struts. In one embodiment, the free ends of the cable guide can be releasably coupled to the projections via a click connection. For this purpose, the coupling element is advantageously designed as a nose-like extension.

[0017] In a further advantageous embodiment, at least one cable guide is designed as a plastic tab. This is advantageous because it provides a resilient property for the cable guide. For example, the cable guide can be U-shaped. In this case, the two free ends on the legs each have a nose-like extension. If a compressive force is now exerted on the two free ends of the U-shaped cable guide, the two ends are guided towards each other. This makes it possible to guide the cable guide from below into the plastic multi-purpose component. More precisely, it is possible to guide the cable guide between two opposing projections of two opposing connecting struts.When the compressive force is then removed, the restoring force causes the free ends to move apart again. This advantageously creates at least a positive and / or non-positive connection with the projections of the connecting struts. The projections of the connecting struts advantageously engage under the nose-like extensions of the free ends, thus creating a secure yet reversible attachment. Subsequently, it is possible to pass at least one supply line through the thus created tab.

[0018] However, this is of course not to be understood as limiting; it is also conceivable that the at least one supply line is already partially inserted into the at least one line guide means before the reversible fastening thereof. The particularly advantageous provision of the projections of the connecting struts creates a high degree of individuality and flexibility, allowing multiple supply lines to be reversibly arranged on the underside of the plastic multi-purpose component as needed, thus forming a plastic multi-purpose system.

[0019] In a further advantageous embodiment, a portion of the connecting struts has at least one through-hole through which a supply line can be passed without crushing. This is advantageous because at least one supply line can be arranged beneath a flatly laid plastic multi-purpose system without compromising its function. The at least one through-hole is also to be understood as a guide for the at least one supply line.

[0020] In a further advantageous embodiment, the plastic multi-purpose system further comprises at least one supply line. In an advantageous embodiment, the at least one supply line is designed as a water pipe or drip hose. This is advantageous because it can provide irrigation and / or drainage. It has also proven particularly advantageous if the at least one supply line is designed to be at least partially or sectionally permeable to water. This makes it possible, on the one hand, to supply the floor area in which the plastic multi-purpose system is arranged with water. The low-lying arrangement of the at least one supply line on the underside of the plastic multi-purpose component prevents unnecessary evaporation in warm or hot environments.Provided water can rise upwards toward the surface of the plastic multi-purpose system via capillary action. This ensures a constant level of basic humidity while simultaneously providing significant protection against evaporation.

[0021] This is, of course, not to be understood as limiting; the at least one supply line described here is also designed for drainage. For example, if the plastic multi-purpose system is positioned at least partially submerged due to heavy rain, standing water can be directly drained away via the at least one supply line and its openings, which are provided at least in sections. This can advantageously prevent damage to buildings or softening of the road surface due to heavy traffic. This can be achieved, for example, by means of at least one coupled pump.

[0022] In a further advantageous embodiment, the cylindrical hollow bodies are delimited on one side, at least in section, by a base section. This is advantageous because the base section forms a lower boundary. This makes it possible for the plastic multi-purpose system to be quickly and easily positioned and leveled on the subsurface to be installed. Furthermore, the base section serves to stabilize the plastic multi-purpose system against external forces, for example when driving over it with heavy goods vehicles. In order to provide the best possible drainage, it has proven advantageous if the base section is not closed. It is particularly advantageous if the base section is provided with openings so that any accumulated water can be drained directly from the cylindrical hollow body into the surrounding soil.

[0023] The openings in the base section also have another function. For example, it has proven advantageous that the centrally located opening in the base section can also have a fixing function in addition to its drainage function. This makes it possible, for example, to thread a ground spike or earth spike through this central opening for long-term fastening under particularly high loads. The ground spike or earth spike advantageously has an enlarged material at its upper free end so that it can span the base section, at least in sections, and fix it accordingly to the ground. In the simplest case, the ground spike or earth spike is inserted by applying compressive force, for example by hammering it into the ground.

[0024] Of course, this is not to be understood as a limitation; it is also conceivable that a ground spike or earth spike could be screwed into the ground, ensuring stable and permanent fixation of the plastic multi-purpose component even under very heavy loads. This is particularly advantageous if only a single plastic multi-purpose component is to be used. The ground spike or earth spike can provide secure ground fixation even when a plastic multi-purpose component is used individually.

[0025] Furthermore, in a further advantageous embodiment, further openings can be provided in the base section. For example, it is possible to provide at least one, advantageously two, further through-openings offset outwards relative to the central opening. These can also be smaller in diameter than the central opening. This at least one further through-opening in the base section proves advantageous for arranging a further component, for example in the form of a rod, post or other geometric body which advantageously extends upwards in the vertical direction. For example, fixing means such as screws or nails can be passed through these through-openings to additionally secure and fix the body which extends upwards in the vertical direction and which is arranged at least with its lower free end in the cylindrical hollow body.

[0026] This, too, is not limiting and should be understood as meaning that it is also conceivable for the geometric body, which advantageously extends vertically upwards, to have at least one or more projections at its lower free end, which can be inserted into the at least one, advantageously 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.

[0027] In another advantageous embodiment, the floor section is connected to the shell surface via floor struts. This also further increases stability.

[0028] It is advantageous to provide openings between the base section and the base struts so that any accumulated water can be drained away from the cylindrical hollow bodies.

[0029] In a further advantageous embodiment, imaginary extensions of the connecting struts converge and / or intersect at the center of the respective floor section. This has proven particularly advantageous because these intersection points allow circular radii to be formed. This is particularly the case when at least two repeating units are provided in the plastic multi-purpose system. These additional circular radii make it possible for the plastic multi-purpose system described here to have additional stability, thus ensuring that the known truck tire treads do not interact with the geometry of the plastic multi-purpose system and hook into it. This permanently ensures that the plastic multi-purpose system can be used reliably and without tipping over for driveways used by heavy-duty vehicles.Complex repair work for shifted or tilted components is no longer necessary, resulting in significant cost savings.

[0030] Depending on the requirements, the plastic multi-purpose system described here can have a different number of repeat units.

[0031] This results in a highly stable plastic multi-purpose system that can easily and quickly divert and distribute external forces, for example from the tires of a heavy-duty vehicle.

[0032] It should also be noted that the use described here with heavy-duty vehicles is, of course, not intended to be limiting, but also includes any use of roadways with trucks, such as fire department bypasses, shunting areas of industrial buildings, escape routes, and the like. The plastic multi-purpose system described here can thus be used to provide permanent, reliable, and safe road surfaces for heavily used roadways. The special geometric design of the plastic multi-purpose system prevents it from being lifted, dislodged, or moved. This ensures that the respective roadway can always be used safely.

[0033] In a further advantageous embodiment, some of the connecting struts are curved with a mirror-symmetrical appearance to one another. This has proven advantageous because this mirror-symmetrical design ensures particularly high stability against external forces. Twisting or breaking of the plastic multi-purpose system is thus ruled out. The connecting struts can particularly advantageously be designed both with mirror-symmetrical appearance and with point-symmetrical appearance to one another. It has proven particularly advantageous if the individual connecting struts are each curved. In this case, the curves can advantageously be arranged opposite one another. This is the case, for example, with the inner connecting struts, which advantageously have at least one projection on their outer surface that also extends outwards.

[0034] In a simple embodiment, for example, it is conceivable that only two repeating units are provided. Consequently, a total of four cylindrical hollow bodies are arranged, advantageously symmetrically to one another and spaced from one another. Two cylindrical hollow bodies each form a repeating unit with the connecting struts running between them. To ensure sufficient stability of the entire plastic multi-purpose system, the individual repeating units themselves are in turn connected to one another via the cylindrical hollow bodies with further connecting struts running between them. These connecting struts are also particularly advantageously arranged symmetrically to one another and opposite one another. It has proven particularly advantageous if all connecting struts of the plastic multi-purpose component described here have the same longitudinal extent.If the geometry described here is viewed from above, the four outer connecting struts form a complete circle. This also provides additional stability and improved force dissipation, especially during heavy-duty use.

[0035] If, however, a larger plastic multi-purpose system is required, this can also be spanned by nine or more cylindrical hollow bodies, which in turn are connected to adjacent cylindrical hollow bodies via at least two or more connecting struts. It is particularly advantageous for the plastic multi-purpose system to be flush on the outside. For example, if a cylindrical hollow body is arranged centrally in the plastic multi-purpose system, it is connected to the other cylindrical hollow bodies regularly arranged adjacent to it via a total of eight connecting struts.

[0036] A cylindrical hollow body at one corner of the plastic multi-purpose system, on the other hand, has only two other cylindrical hollow bodies arranged regularly next to each other, resulting in a total of four connecting struts.

[0037] If nine cylindrical hollow bodies are provided, a portion of the connecting struts forms a total of four closed circles. It has proven advantageous for the stability of the entire plastic multi-purpose system that two adjacent circles always form a common intersection. This further prevents the truck tires from prying the structure open.

[0038] In a further advantageous embodiment, an outwardly extending coupling means is arranged on a lateral surface of at least one cylindrical hollow body and / or at least one passage opening is provided on a lateral surface of at least one cylindrical hollow body. This is advantageous because it allows the surface composite to be formed. Individual plastic multi-purpose systems can thus be laid directly adjacent to one another. The at least one outwardly extending coupling means and the passage openings also provided accordingly make it possible to securely connect several plastic multi-purpose systems to one another, thus creating a surface composite. This is advantageous because it prevents an individual plastic multi-purpose system from tipping over and can provide a highly stable, durable surface composite shape.

[0039] 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 composite, a coupling means of a first plastic multi-purpose system can be inserted into a passage opening of a further plastic multi-purpose system arranged adjacent to it and connected to this in an advantageous locking position. For this purpose, both the coupling means and advantageously the wall of the passage opening each have a corresponding projection which, once inserted into one another, engage over or under one another and thus form a positive and / or non-positive connection. This prevents undesired slipping out and dissolution of the surface composite, which can be formed by several plastic multi-purpose systems described here.

[0040] In a further advantageous embodiment, each connecting strut has at least one through-hole. This is additionally advantageous because it allows for the passage of cables. This is relevant, for example, if irrigation lines are laid beneath the plastic multi-purpose component. The through-holes allow the irrigation lines to continue functioning and prevent them from being crushed or damaged by the plastic multi-purpose components.

[0041] In a further advantageous embodiment, the at least one passage opening extends vertically from bottom to top in a portion of the connecting struts. This is advantageous because it allows the possible hoses for improvements to be arranged particularly easily in the corresponding passage openings without damaging the hoses themselves.

[0042] In a further advantageous embodiment, the vertical extension of the connecting strut's through-hole is smaller than the vertical through-hole of the cylindrical hollow body. This is advantageous because the connecting strut's through-holes are designed to accommodate irrigation. The through-holes in the lateral surfaces, however, are necessary so that the coupling elements of adjacent plastic multi-purpose systems can be at least partially inserted and coupled together.

[0043] Furthermore, the present invention relates to different uses of a plastic multi-purpose system. For example, it has proven advantageous to use the plastic multi-purpose system as a modular component of a flat composite for heavy-duty traffic. In particular, due to the known tire treads of heavy-duty trucks, the plastic multi-purpose system described here for the first time can be guided over even during tight turning maneuvers or small-wheel axle steering of a rear axle, without the tire tread hooking into the geometry of the plastic multi-purpose system and lifting it out of the composite, or perhaps even shifting it. This makes it possible for the first time to provide a plastic multi-purpose system that can be laid in a flat composite and that can be used permanently, especially for roadways with heavy-duty traffic.

[0044] The flat composite of a multitude of plastic multi-purpose systems is particularly advantageous when laid flat. The plastic multi-purpose systems are connected to one another using the coupling mechanism described above. Due to the special geometry of the plastic multi-purpose system, it can also be used in escape routes, parking lots, roadways subject to high and heavy loads, or even for fire department access routes. The special geometry between the connecting struts and the cylindrical hollow bodies prevents the individual plastic multi-purpose systems, which can also be referred to as modules, from being pried open or shifted out of the flat composite when heavy-duty vehicles drive over them and / or perform turning maneuvers on them.

[0045] At the same time, the at least one supply line, advantageously several supply lines, makes it possible to provide indirect irrigation in the upper soil. This prevents plants from being damaged on hot days when irrigation is carried out and / or the applied water from evaporating again very quickly, as is the case with conventional lawn sprinklers, for example. With the indirect irrigation of fire department access roads, escape routes or other heavily used road surfaces for heavy goods vehicles provided here, irrigation takes place in a range of approximately 4 to 15 cm below the direct soil surface. This depends on the height of the plastic multi-purpose system. In this example of use, the flatly laid plastic multi-purpose system forms the upper road surface directly, so that irrigation can take place from below.This allows moisture to be provided from below, which can spread upwards via capillary action. This makes it possible to indirectly water driveways for heavy goods vehicles, so that they remain attractively green even in summer or in particularly dry regions, without wasting too much water through direct irrigation. At the same time, it is possible to provide a subsoil with a predeterminable moisture level. This can also prevent soil cracking and hardening. It has proven particularly advantageous to measure soil moisture using at least one sensor and regulate the irrigation intensity accordingly using at least one control unit.

[0046] Another advantageous use of the flat-laying plastic multi-purpose system is as a retention plate on the ground and / or on flat roofs. This is advantageous because the at least one supply line, which can be laid without crushing through the openings in the connecting struts, allows green roofs that are particularly susceptible to drought to be supplied with sufficient moisture quickly and easily. Here, too, it is advantageous that the at least one supply line does not run directly on the subsurface, but rather at a depth of 10-35 cm. It is particularly advantageous if the provided assembly is at least filled with soil and / or covered with soil to a depth of 5-25 cm. This provides sufficient soil material for planting. Thus, moisture can 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 wasting too much water through direct irrigation. At the same time, it is possible to provide a subsoil with a pre-determined moisture content. This can also prevent soil cracks and hardening. It has proven particularly advantageous if the soil moisture is recorded by at least one sensor and the irrigation intensity is regulated accordingly via at least one control unit. At the same time, the plastic system described here makes it possible to drain standing water on roofs in the event of heavy rainfall. This can be done, for example, using at least one connectable pump, which actively pumps out the standing water once a pre-determined water level is reached.For this purpose, at least one sensor can also be advantageously provided which detects the water level.

[0047] Finally, the plastic multi-purpose system described here can also be used in a third way. It has proven particularly advantageous to use the plastic multi-purpose system as a surface-laid composite for the irrigation and / or drainage of equestrian facilities, riding arenas, indoor riding arenas, or riding arenas, both indoors and outdoors. In equestrian sports in particular, it has been common practice to moisten riding arenas using the so-called "ebb and flow" method. This involves flooding sand arenas, for example, with water to prevent dust buildup on hot, dry days. At the same time, this watering firms the sand, giving the horses a sure footing and making riding easier on the horses' joints. This method is disadvantageous in that it constantly consumes a lot of water and does not provide a permanently, evenly moist surface.With the modular plastic multi-purpose system described here, which can be laid as a flat composite, it is possible to provide consistent, permanent soil moisture.

[0048] For this application, it has proven advantageous if the plastic multi-purpose system is laid in the ground, for example at a depth of 10-20 cm. It is advantageous to add sand directly above the plastic multi-purpose system, which is laid as a flat composite, to create a sand footing for the horses. If the plastic multi-purpose system is then watered from below using, preferably 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 multi-purpose system described here directly in the ground without the need for any additional tools.No additional protection of the supply lines is necessary, as these are already integrated into the underside of the plastic multi-purpose systems and thus secured. It is therefore possible to install the plastic multi-purpose system described here in a flat, interconnected system, 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.

[0049] Furthermore, the plastic multi-purpose component described here can also be used as an individual foundation for posts, advantageously made of wood or plastic, fence posts, advantageously made of wood or plastic, sign posts, advantageously made of wood or plastic, or the like.

[0050] To ensure sufficient adhesion to the ground, the heavy-duty plastic multi-purpose component filled with free-flowing material may be too light to be securely 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 base sections of the heavy-duty plastic multi-purpose component to the ground. In the simplest case, ground spikes or earth spikes are driven or screwed through at least one central opening in a base section. This method is reversible and can be removed again.

[0051] It has proven particularly advantageous if the plastic multi-purpose system is made at least partially, preferably entirely, of thermoplastic material. Examples of this are advantageous olefins, such as polypropylene and / or polyethylene.

[0052] The plastic used can be, for example, 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, and polypropylene are used.

[0053] To achieve sufficient stabilization of the multi-purpose plastic system 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. It is also conceivable to use other free-flowing materials, such as stones, sand, gravel, or mixtures thereof.

[0054] It is also advantageous to construct the cable routing elements from plastic. This proves to be corrosion-resistant and durable. In the simplest case, polyolefins such as polyethylene and / or polypropylene can be selected for this purpose.

[0055] Further advantages, features and design options emerge from the following description of figures of non-limiting embodiments. Brief description of the drawings

[0057] Elements provided with the same reference numerals in the drawings essentially correspond to one another unless otherwise stated.

Detailed description of implementation examples

[0058] Fig. Figure 1 shows a top view of a first embodiment of the plastic multi-purpose component 100. It shows a total of nine cylindrical hollow bodies 102, which are at least partially bounded at the bottom by a bottom section 104. As shown, the bottom sections 104 are designed to be discontinuous, so that, for example, waterlogging can be drained directly into the surrounding soil.

[0059] Two cylindrical hollow bodies 102 are each permanently connected by two connecting struts 106a, 106b. A distinction must be made between a first connecting strut 106a and a second connecting strut 106b. This forms the repeating unit. It can be seen that the two connecting struts 106a, 106b are symmetrical to each other in their curvature K.

[0060] In this exemplary embodiment, the connecting strut 106b has at least one projection 108 on its outer side. This projection 108 can be used, for example, for the subsequent arrangement of a watering hose (not shown here), in that it can be locked directly or held using possible aids. The cylindrical hollow bodies 102 each partially have an outwardly directed coupling means 110. This coupling means 110 is T-shaped in plan view. It is required to connect several plastic multi-purpose components 100 to one another, so that a planar composite, for example as a floor covering, can be formed.

[0061] The base sections 104 are connected to the lateral surfaces of the cylindrical hollow bodies 102 via base struts 112. In this exemplary embodiment, the base struts 112 are of the same thickness as the connecting struts 106a, 106b. The base struts 112 can therefore be viewed as an extension of the connecting struts 106a, 106b. The center point 114 of each base section 104 forms an intersection point of the extended connecting struts 106a, 106b.

[0062] In Fig. Figure 2 shows another embodiment. The plastic multi-purpose component 200 shown here is also shown in plan view. Here, a total of nine cylindrical hollow bodies 202 are shown, which are at least partially bounded at the bottom by a bottom section 204. As shown, the bottom sections 204 are designed to be discontinuous, so that, for example, waterlogging can be drained directly into the surrounding soil.

[0063] Two cylindrical hollow bodies 202 are each permanently connected by two connecting struts 206a, 206b. A distinction must be made between a first connecting strut 206a and a second connecting strut 206b. This forms the repeating unit. It can be seen that the two connecting struts 206a, 206b are symmetrical to each other in their curvature K.

[0064] In this exemplary embodiment, the connecting strut 206b has at least one projection 208 on its outer side. This projection 108 can be used, for example, for the subsequent arrangement of a watering hose (not shown here), in that it can be locked directly or held using possible aids. The cylindrical hollow bodies 202 each partially have an outwardly directed coupling means 210. This coupling means 210 is T-shaped in plan view. It is required for connecting several plastic multi-purpose components 200, 100 to one another, so that a planar composite, for example as a floor covering, can be formed.

[0065] The floor sections 204 are connected to the lateral surfaces of the cylindrical hollow bodies 202 via floor struts 212. In this exemplary embodiment, the floor struts 212 are designed to be thicker or wider in some sections than the adjacent connecting struts 206a, 206b. The floor struts 212 can nevertheless still be viewed as an extension of the connecting struts 206a, 206b. The center point 214 of each floor section 204 forms an intersection point of the extended connecting struts 206a, 206b. The embodiment shown here proves advantageous if, for example, installation on a coarse-grained subsurface is desired. In this case, the widened floor sections 204 and the likewise wider floor struts 212 ensure a more break-resistant variant than is the case with the thinner floor struts 112 of the first exemplary embodiment 100.

[0066] At the same time, the center point 214 can also be formed as an opening in the base section 204. In this case, the diameter of the opening can advantageously be differentiated. In the exemplary embodiment shown here, two different diameters of the openings are shown. The cylindrical hollow bodies 202, which are arranged at the corners of the plastic multi-purpose component 200 disclosed here, have three diagonally offset openings 214a. Advantageously, the openings 214a all have the same diameter.

[0067] Particularly advantageously, all of the openings 214a, or at least one of the openings 214a, can be used for the additional fastening of a vertically upwardly extending geometric body, which can be arranged at least partially in the cylindrical hollow body 202. Via the at least one opening 214a, it is possible to connect the vertically upwardly extending geometric body (not shown), more precisely, its free lower end (also not shown), to the base section 204 using fixing means (not shown), such as screws or nails. Particularly advantageously, the fixing means is introduced from the outside, i.e., from the underside of the plastic multi-purpose component, through the at least one opening 214a into the interior volume of the cylindrical hollow body 202 and simultaneously into the free end of the geometric body (not shown), thereby fixing the latter.

[0068] Furthermore, another type of opening 214b can advantageously be provided. This additional type has a significantly larger diameter than the openings 214a. This is advantageous because these openings 214b are used for additional fixation of the plastic multi-purpose component 200 to the substrate. In this exemplary embodiment, a total of four openings 214b are provided. Particularly advantageously, the at least one opening 214b is provided centrally in the base section 204.

[0069] The additional fixation of the plastic multi-purpose component 200 is advantageous if it is to be used as a single module, i.e., on its own without being laid in a composite structure. If the plastic multi-purpose component 200 is used as a single module, there is a risk that, despite filling the chamber-like structure with a free-flowing material, the total weight of the plastic multi-purpose component 200 and the free-flowing material arranged therein will be too low to ensure sufficient slip resistance on the subsurface. Therefore, some of the base sections 204 can each have a centrally arranged opening 214b. This opening 214b is used to guide a ground spike or ground rod (both not shown) through the respective cylindrical hollow body 202 and through the opening 214b into the subsurface directly adjacent to it. The guiding is particularly advantageously carried out by hammering or screwing.This makes it possible to safely arrange individual heavy-duty plastic multi-purpose components 200 on the surface.

[0070] Depending on the expected load and also depending on the respective subsurface, the plastic multi-purpose component 200 can advantageously be fixed to the subsurface in a slip-resistant and displacement-proof manner via at least one opening 214b, but also advantageously all openings 214b, using ground spikes or ground spikes (not shown). This is not to be understood as limiting; therefore, plastic multi-purpose components laid as a flat, coupled composite can also be at least partially additionally secured to the subsurface with such fixings.

[0071] In the perspective view of the plastic multi-purpose component 100, 200 in Fig. 3 further shows that four adjacent cylindrical hollow bodies 102, 202, with the connecting struts 106a, 106b, 206a, 206b connecting them, form a full circle V. Due to the highly symmetrical design of the cylindrical hollow bodies 102; 202 and the connecting struts 106a, 106b, 206a, 206b, the full circles V form intersecting sectional surfaces S.

[0072] Furthermore, this perspective view shows that the connecting struts 106a, 206a have passage openings 116, 216 in their lower region. These passage openings 116, 216 are advantageously provided to allow optional irrigation or other lines to pass underneath the plastic multi-purpose component 100, 200 without causing crushing or damage to the lines.

[0073] Also shown are the through-openings 118, 218, which interrupt the lateral surfaces of the cylindrical hollow bodies 102, 202. These through-openings 118, 218 extend vertically upward. These through-openings 118, 218 are required so that coupling means 110, 210 from adjacent plastic multi-purpose components 100, 200 can be introduced and coupled therein. This makes it possible to form a modular surface assembly from several interconnected plastic multi-purpose components 100, 200.

[0074] Furthermore, it is shown that the passage openings 116,216 are lower in their vertical extent than the passage openings 118,218.

[0075] In Fig. Figure 4 shows a perspective bottom view of the first exemplary embodiment. The underside of the plastic multi-purpose component 100 has, in addition to the previously described base sections 104, aligned through-openings 116. This arrangement of the through-openings 116 in the connecting struts 106a, 106b is advantageous because it allows cables or hoses (not shown) to be particularly easily routed both into and out of the plastic multi-purpose component 100 without resulting in crushing or damage.

[0076] The passage openings 118, on the other hand, only interrupt a part of the lateral surface of the cylindrical hollow bodies 102, so that it is ensured that the coupling means 110 of adjacently arranged plastic multi-purpose components 100, 200 can be inserted and locked therein.

[0077] Finally, Fig. 5 shows a perspective bottom view of embodiment 2. The plastic multi-purpose component 200 shown here also has the through-openings 218, which interrupt the lateral surfaces of the cylindrical hollow bodies 202. Furthermore, the through-openings 216 are also provided here in alignment with one another, so that here too, cables or hoses (not shown) can be laid both into the plastic multi-purpose component 200 and out of it. It is also evident that the aligned alignment of the through-openings 216 can be implemented both longitudinally and transversely.

[0078] Furthermore, the two types of openings 214a and 214b are also shown. Both types of openings 214a, 214b are continuous. Furthermore, the bottom section 204 of the centrally arranged cylindrical hollow body 202 has a different geometry than the bottom sections 204 of the other cylindrical hollow bodies 202.

[0079] To ensure particularly effective production of the plastic multi-purpose component 200 shown here, in particular to enable its production by injection molding, it has proven advantageous not to provide a through-opening 214a or 214b in the base section 204 of the central cylindrical hollow body 202. Instead of the through-openings 214a, 214b, only a material bulge 215 is provided. This ensures easy demolding from the cavity during the injection molding process.

[0080] In Fig. 6 shows a top view of a plastic multi-purpose system 300. The second embodiment is shown here as the plastic multi-purpose component 200. Naturally, this is not limiting, but merely an example. Regarding the reference numerals of the plastic multi-purpose component 200, reference is made to Fig. 2. Identical components are also marked with the same reference numerals.

[0081] In addition to the plastic multi-purpose component 200 made of Fig. 2 shows a plastic multi-purpose system 300 which further comprises two supply lines 303. In this exemplary embodiment, the supply lines 303 are aligned orthogonally to one another. Furthermore, it can be seen that both supply lines 303 are arranged so as to protrude beyond the edge of the plastic multi-purpose component 200. This is particularly relevant for the subsequent assembly of the plastic multi-purpose system 300, namely when several of the modules 200 shown here are arranged next to one another so that a flat, laid composite is formed. In this context, it is likewise important that the supply lines 303 can be coupled or connected to one another. This ensures a reliable supply, for example with water. The supply lines 303 are particularly advantageously designed here as water pipes.

[0082] In order to securely connect the supply lines 303 to the plastic multi-purpose component 200, the free ends of two line guides 301 are shown here, as an example, in a top view. The line guides 301 are designed such that they can be connected to the projections 208 of the connecting struts 206a, 206b via a click mechanism by means of a positive and / or non-positive connection. Advantageously, the line guides 301 are designed as tabs into which the supply lines 303 can be placed, at least in sections. The supply lines 303 are thus gripped from under by the line guides 301, at least in sections, and thus stabilized.

[0083] In Fig. 7 is a bottom perspective view of the plastic multi-purpose system 300 of Fig. 6. The two supply lines 303 are also shown here. The base area of ​​the plastic multi-purpose component 200 is shown in black. The base area refers to the area that is placed on the floor during installation. It is thus evident that both the floor sections 204 and the connecting struts 206a, 206b, as well as the lower edges of the hook-shaped elements 210, lie in one plane. This facilitates assembly and ensures that a flat, installable composite can be formed.

[0084] Furthermore, in this bottom view, the cable guide means 301 are shown as tab-like elements. It can be seen that the supply lines 303, which in the simplest case can be designed as water lines, are gripped underneath by the cable guide means 301 and thus held.

[0085] In Fig. Figure 8 shows a further perspective view of the plastic multi-purpose system 300, whereby it should be noted that here too the surface is fully structured. This perspective view also illustrates how the two supply lines 303 can be arranged below the plastic multi-purpose component 200, 100 without crushing. Particularly advantageously, the through-openings 116, 216 correspond at least to the height or diameter of the supply lines 303. This makes it possible for the supply lines 303 to be at least flush with the lower end edge of the plastic multi-purpose component 100, 200. Consequently, crushing of the supply lines 303 is avoided. Excessive play of the supply lines 303 within the through-openings is also avoided, so that a reliable supply, for example with water, can always be guaranteed.

[0086] The plastic multi-purpose component 100,200 in Fig. 9 is a sectional view along the vertical axis of Fig. 6. The left-hand section of the image shows projections 108, 208 arranged on the connecting struts 106, 206. Particularly advantageously, the projections 108, 208 are designed such that the passage opening 116, 216 arranged underneath remains freely accessible. For increased stability of the projections 108, 208, they are not merely formed by a projection extending horizontally away from the connecting struts. Particularly advantageously, the projections 108, 208 are designed in a gate-like manner next to the support surface, so that two lateral stabilizing thickenings 109, 209 are advantageously provided, which connect and stabilize the support surface for the free ends of the cable guide means 301.

[0087] The right-hand section then shows a supply line 303, which rests on the line guide means 301 and is gripped and held by it. Furthermore, a free end of the line guide means 301 is shown here as an example, which is coupled as a nose-like extension 302 to the projection 108, 208 in a form-fitting and / or force-fitting manner. Particularly advantageously, the free ends of the line guide means 301 are resiliently designed and can be guided toward one another, for example, under the application of compressive force. Consequently, the free ends are tensioned.

[0088] In this tensioned state, it is possible to insert the free ends from below into the plastic multi-purpose component 100, 200 and guide them past the projections 108, 208, which are advantageously arranged opposite one another. Once the compressive force is removed, the nose-like projections 302 are repositioned due to the restoring force and can be gripped by the projections 108, 208, or more precisely, by the respective support surface.

[0089] This is, of course, not to be understood as limiting; it is also conceivable that, due to the special geometric design of the nose-like extensions 302, they initially make contact with the projection 108, 208 upon insertion into the plastic multi-purpose component 100, 200 from below. This contact also generates a compressive force, causing the nose-like extensions 302 to be resiliently deflected and guided toward one another. By compressing the free ends, or more precisely, the nose-like extensions 302, they can be easily and quickly guided past the projections 108, 208.

[0090] Once the passage is complete, the resilient free ends of the cable guide means 301 expand again due to the restoring force and snap back over the contact surfaces of the projections 108, 208. Thus, each contact surface can engage under the respective nose-like extension 302 and retain itself.

[0091] To further ensure improved stabilization between the cable guide means 301 and the supply lines 303, it is optionally advantageous if the at least one supply line has at least one recess 305 into which at least a portion of the cable guide means 301 can be inserted. In the simplest case, this can be designed as an additional click or snap connection.
