Description

Prior art The invention concerns a modular support post system according to the preamble of claim 1, a construction kit according to claim 9, a support post according to the preamble of claim 13, a protective net installation according to claim 33 and two methods according to claims 34 and 35. From the prior art, e. g. the European patent application EP 1 911 884 A1, a plurality of different support posts for protective net installations are known. The support posts known from the prior art are realized as steel support posts which are assembled in one piece or welded in in a one-part implementation, and which are designed and manufactured depending on the individual requirements for the respective protective net installations, so that the respectively required heights, energy classes etc. can be achieved. Such project-related manufacture of the complete support posts is usually very labor-intensive. The complete manufacture of the known support posts takes place by manufacturing at the support post producer and the support posts are then delivered in one piece to the construction site of the protective net installation. Protective net installations are frequently installed at difficult-to-reach, e. g. mountainous, locations. Therefore the logistics for delivering the support post to the intended installation site may require huge efforts. The prefabricated support posts are usually brought to the intended installation site by helicopters. The heavier and / or more spatially projecting a support post is that is to be delivered by the helicopter, the more cost-intensive and time-intensive its installation will be. The objective of the invention is in particular to provide a generic device with advantageous properties regarding efficiency, in particular with regard to resources, cost expenditure and / or time expenditure. The objective is achieved according to the invention by the features of the independent patent claims, while advantageous implementations and further developments of the invention may be gathered from the subclaims. Advantages of the invention The invention is based on a modular support post system for producing a support post for a protective net installation, comprising at least one beam, in particular a profile beam, comprising at least one support post foot part, and comprising at least one support post head part. It is proposed that at least the support post foot part and / or at least the support post head part are / is (in each case) realized as an, in particular prefabricated, modular component that can be fixed to the beam. As a result, a high degree of efficiency is advantageously achievable. Advantageously, a production effort can be reduced, in particular as it is possible to switch from project-related individual production to series production of modular components. This advantageously allows saving costs, production time and / or resources. Advantageously, the modular support post system allows on-site manufacturing of support posts for protective net installations, i. e. in particular at the location of the construction site. As a result of the associated reduction in size of the individual components that are to be transported, it is advantageously possible to reduce a required logistics effort, in particular with regard to costs and / or resource consumption / CO2 production. Advantageously, identical modular components can be used for different protective net installation systems. Moreover, repair can advantageously be simplified, in particular since it is not always necessary to replace entire support posts, but rather only damaged modular components of support posts need to be replaced. It is also advantageously possible, in contrast to previous project-related individual manufacture, to enable storage of the modular components, such that preferably an availability / delivery time of support posts can be advantageously reduced. Furthermore, it is advantageously possible to reduce a space requirement for storage, for example as it is significantly easier to stack individual beams than fully-assembled support posts having a support post head part and a support post foot part. Advantageously, fewer protective measures will be necessary for the protection against damage during storage and during transport (for example, during transport of a fully-assembled support post, it must be ensured that not the entire weight of the beam acts on portions of the support post head part). Moreover, the modular construction advantageously allows achieving resource-saving shortening of delivery paths, for example as it is now possible, in particular because of the structural simplicity of modular components in comparison with prefabricated complete support posts, to procure individual modular components on-site, e. g. in the respective country in which the protective net installation is to be installed. For example, it is advantageously possible to use locally available steel profiles for modular components of a beam, instead of having to ship the steel profiles from a central production site all over the world. This advantageously allows improving environmental sustainability, e. g. by reducing CO2 production due to shortened delivery paths. In addition, a high degree of flexibility is advantageously achievable. For example, it is advantageously possible to enable adaption of a shape or a design of a support post on-site at the construction site by exchanging a modular component. A support post is preferably realized as a component that is mostly vertical (at least when viewed relative to a ground level). In particular, the support post is configured for receiving and forwarding loads. In particular, the support post is configured for suspending and / or holding at least one cable of a protective net installation and / or of at least one protective netting, preferably a steel-wire protective netting, of a protective net installation. In particular, the support post is configured for suspending and / or holding a net-and-cable construction. A “modular component” is in particular to mean a technical unit that can be joined with other technical units to form a higher-quality whole, in particular the support post. In particular, individual modular components can be combined to form the whole in different ways, depending on requirements and / or on customers' wishes. Advantageously, the modular components form elements of a construction kit system. Advantageously, a modular component implements an exchangeable complex element within an overall system which forms a closed functional unit. In particular, in the modular construction a system, in particular the support post, is composed of the modular components along defined places, in particular along defined interfaces. In particular, the interfaces of all, in particular functionally identical, modules are realized so as to be identical and / or compatible with one another. The modular support post system in particular comprises a plurality of modular components which can be combined with one another and can be joined to form a support post. In particular, each modular component of the modular support post system has at least one interface that is configured for a mounting of the modular component to a further modular component, which is preferably functionally different from the modular component. The beam is in particular likewise realized as a modular component of the modular support post system. In particular, each implementation of the modular component that is a support post foot part of the modular support post system has at least one beam interface allowing and enabling a fixing of the respective support post foot part to each implementation of the modular component that is a beam. In particular, each implementation of the modular component that is a support post head part of the modular support post system has at least one beam interface allowing and enabling a fixing of the respective support post foot part to each implementation of the modular component that is a beam. In particular, each implementation of the modular component that is a beam of the modular support post system has at least one support post foot part interface allowing and enabling a fixing of the respective beam to each implementation of the modular component that is a support post foot part. In particular, each implementation of the modular component that is a beam of the modular support post system has at least one support post head part interface allowing and enabling a fixing of the respective beam to each implementation of the modular component that is a support post head part. The beam interfaces, the support post head part interfaces and / or the support post foot part interfaces may herein be realized as plug-in interfaces, as screw-connection interfaces, as clamping interfaces, as gluing interfaces or the like. "Configured” is in particular to mean specifically programmed, designed and / or equipped. By an object being configured for a specific function is in particular to be understood that the object fulfils and / or carries out this specific function in at least one application state and / or operation state. The beam in particular forms a middle part of the support post. Preferably, the beam extends at least over a large portion of a total longitudinal extent of the support post. A large portion is to mean in particular 51%, preferably 60%, preferably 70% and particularly preferably 85%. In particular, the beam essentially defines a load-bearing capacity of the support post. The beam may be realized as a profile beam with a cross section that remains substantially constant along its longitudinal extent. Alternatively, however, the beam could also have varying cross sections along its longitudinal extent. In particular, the beam may be realized in the manner of a joist. The support post foot part in particular forms a first support post end region of the support post. Preferably, the support post foot part is configured for to be fixed to a first beam end region of the beam. In particular, the support post foot part forms an adapter component for a connection of the beam to a base plate. The base plate is preferably configured for a mounting of the support post on a ground, e. g. a rock or a concrete foundation. The support post head part in particular forms a second support post end region of the support post, which is in particular situated opposite the first support post end region. Preferably, the support post head part is configured for to be fixed to a second beam end region of the beam, which is in particular situated opposite the first beam end region. In particular, the support post head part forms an adapter part for a mounting of cables of the protective net installation. In particular, the support post head part comprises cable guides for guiding cables of the protective net installation. The protective net installation is in particular realized as a rockfall barrier, as a debris flow barrier, as a shallow-landslide barrier, as an avalanche protection barrier, as a temporary or permanent road barrier, as a coast protection barrier, as an anti-cave-in barrier, as a motor sports barrier, as a mine protection barrier, as a counter-terrorism barrier or as a further protective net barrier held by support posts. In particular, the support post is produced by a joining of at least two, preferably at least three, modular components of the modular support post system. However, it is conceivable that the support post consists of more than three modular components or that, in addition to the three modular components, further modular components can be added to the support post optionally. By “prefabricated modular components” are in particular modular components to be understood which are manufactured, preferably manufactured in series, without specific project reference in different implementations, for example strengths, sizes, materials, etc. Advantageously, the modular support post system allows a production of a very large number of different support posts from a relatively small, in particular constant, pool of modular components. Advantageously, the modular support post system allows a production of support posts for a great variety of types of protective net installations from a relatively small, in particular constant, pool of modular components. Furthermore, weld-free mountability of the support post foot part and / or of the support post head part on the beam is proposed. This advantageously allows simplifying production and / or mounting, in particular also on-site at a construction site. Advantageously, good environmental sustainability can be achieved by dispensing with an energy-intensive joining method such as welding. Advantageously, in this way improvement of quality and / or saving of transport costs for an installation of a protective net installation in more remote and / or less developed regions of the world, in which there is a lack of experts and of material for good welding work, are / is achievable. This is advantageous in particular since suppliers who are permitted to weld components of protective net installations must be certified according to EN 1090-1 2009+A1:2011 and to EN 1090-2_2020, and / or must be able to carry out standardized visual tests according to EN ISO 17637:2011. Otherwise, there may be (EAD = European Assessment Document) approval problems for the protective net installations. Thus, if weld-free mounting is possible, this working step can advantageously be carried out everywhere in the world and on-site. In this way approval problems for protective net installations having the support posts according to the invention are advantageously avoided. Advantageously, during the inland mounting of the support post a working step (welding) at a metal builder's can also be dispensed with, as a result of which in particular time, transport costs, transport resources and labor costs can be saved. It is advantageously possible, in particular with critical production steps, to reduce a proportion of manual work, which advantageously allows reducing a risk of error. Furthermore, advantageously utilization of non-weldable materials is enabled, providing additional advantages with regard to weight (for example non-weldable carbon steel, aramid, HDPE, basalt, carbon fiber), to ecology (for example wood or bamboo), to material costs (e. g. glass-fiber-reinforced plastics), etc. Preferably, the support post foot part, the support post head part and / or the beam are / is made of a difficult-to-weld or a non-weldable material. In particular, the support post foot part and / or the support post head part can be mounted on the beam by screwing, by clamping, by plugging together, for example via a press fit, and / or by adhesive bonding with the beam. Furthermore, it is proposed that at least the support post foot part and / or at least the support post head part can be - preferably non-destructively - exchangeably and / or - preferably non-destructively - detachably connected to the beam in order to form the support post. In this way, it is advantageously possible for individual parts of defective protective net installations (for example after a block impact) to be easily and separately exchangeable. In particular, in many cases this allows avoiding exchange of complete support posts. This advantageously allows saving resources, costs and labor expenditure. For example, the support post foot part and / or the support post head part could be mounted on the beam by releasable screwing, by reversible clamping, by detachable plugging together and / or by detachable adhesive bonding with the beam. It is moreover proposed that the modular support post system comprises at least one, in particular prefabricated, further modular component which can be (detachably) fixed to the beam, which is realized as a climbing aid and which is preferably mountable on the beam without welding. This allows further expanding the advantages of the modularity. Advantageously, the support post can be manufactured in a simple manner, optionally with or without a climbing aid. Advantageously, one climbing aid could be sufficient for several support posts of a protective net installation (with demounting from one support post and subsequent mounting on another support post). In particular, the climbing aid is realized such that it can be plugged into recesses of the beam that are provided for this purpose. In particular, the climbing aid is mounted frontally on the beam. As a result, climbing of the support post will be significantly simplified in comparison with a climbing aid that is mounted laterally on the beam, in particular if a protective net has already been suspended. The climbing aid may be composed of several separate step elements. In particular, at least the modular component of the modular support post system that is a beam has at least one climbing aid interface, which allows and enables a fixing of the climbing aid to the beam. The climbing aid interface may herein be realized as plug-in interfaces, as screwconnection interfaces, as clamping interfaces, as gluing interfaces or the like. In addition, it is proposed that the modular support post system comprises at least one, in particular prefabricated, further modular component which can be (detachably) fixed at least to the beam, which is realized as an anti-tilt-back safeguard and which is in particular mountable on the beam without welding, preferably without holes. As a result, a high degree of safety is advantageously achievable. In particular, the anti-tilt-back safeguard is configured to prevent a tipping over of the support post during a mounting of the base plate. In particular, this allows preventing the beam from tilting during an installation of the support post and thus injuring persons or damaging equipment. In particular, the anti-tilt- back safeguard is mounted immediately after the uprighting of the beam. A “connection without holes” of the anti-tilt-back safeguard is in particular to mean a connection of the anti-tilt-back safeguard with the beam that works completely without holes on the beam side, for example for the mounting of screws, shackles or the like. A “connection without welding” of the anti-tilt-back safeguard is in particular to mean a connection of the anti-tilt-back safeguard with the beam that works completely without welding / welding-on of components at least on the beam side. For example, the anti-tilt-back safeguard may be fastened to the beam on the beam side by means of a clamp or by tying to the beam / wrapping around the beam. The opposite-situated fastening of the anti-tilt-back safeguard may be realized in a customary manner, for example by shackling to an eye of the base plate. Beyond this, it is proposed that the modular support post system comprises at least one, in particular prefabricated, further modular component which can be combined with the beam, the support post foot part and / or the support post head part, which is realized as a sensor module and which comprises, for example, at least one pressure sensor, at least one tension sensor, at least one corrosion sensor and / or the like. This advantageously allows increasing safety. Moreover, it is advantageously possible to simplify integration of a sensor system into a protective net installation. Furthermore, it is advantageously possible to retrofit a sensor system into already installed support post systems. In particular, the sensor module itself may in turn be constructed in a modular manner, comprising a variable choice of different sensors, for example pressure sensors, tension sensors, corrosion sensors, weather sensors, gas sensors, light sensors, etc. In particular, at least one modular component of the modular support post system has at least one sensor module interface allowing and enabling a fixing of the sensor module to the respective modular component. The sensor module interface may herein be realized as plug-in interfaces, as screw-connection interfaces, as clamping interfaces, as gluing interfaces or the like. It is also conceivable that the base plate forms a further, in particular prefabricated, modular component which can be combined with the support post foot part. If the beam further comprises at least two beam module components, which can in particular joined in the longitudinal direction of the beam, it is advantageously possible to increase a flexibility of the modular support post system and / or a variety of the support posts that can be produced. Advantageously, a length and / or thickness of the beam can be variably adjusted for the modular support post system. In particular, it is also possible that the beam can be assembled from more than two, for example three, four or more than four beam module components. In particular, the beam module components can be mounted with one another by screwing, by clamping, by plugging together and / or by adhesive bonding. In this context, it is proposed that the beam module components which form the beam by joining have different material thicknesses, different maximum outer diameters and / or different profile types. This advantageously allows increasing a flexibility of the modular support post system and / or a variety of the support posts that can be produced. For example, the beam could become thinner toward the top, i.e. towards the support post head part interface, or could have a more lightweight material or a lower material thickness. Furthermore, a construction kit and / or building set for the modular support post system is proposed, at least comprising two or more, in particular prefabricated, beams and at least comprising two or more, in particular prefabricated, support post foot parts and / or, in particular prefabricated, support post head parts, which can be combined with the beams. As a result, a high degree of efficiency is advantageously achievable. Advantageously, production efforts can be reduced, in particular as it is possible to switch from project-related individual manufacturing to series manufacturing of modular components. This moreover advantageously allows saving costs, production time and / or resources. In particular, the construction kit may additionally comprise two or more different, in particular prefabricated, base plates. In particular, the construction kit may additionally comprise two or more different, in particular prefabricated, climbing aids. In particular, the building set may additionally comprise two or more different, in particular prefabricated, sensor modules. In particular, the construction kit may additionally comprise two or more different, in particular prefabricated, anti-tilt-back safeguards. In particular, the construction kit may additionally comprise two or more different, in particular prefabricated, beam module components. It is further conceivable that the different beams or at least one of the beam module components are / is cut to required lengths, on site or during production, in a flexible manner. It is furthermore proposed that at least two of the beams of the construction kit, at least two of the support post foot parts of the construction kit and / or at least two of the support post head parts of the construction kit have respectively different corrosion protection levels, in particular comprise corrosion protection layers with different compositions or different thicknesses, or comprise surface materials with different corrosion resistance. This advantageously allows adjusting the corrosion resistance for the support post. Advantageously, it is possible to achieve adaptability of protective net installations to local weather differences or to locally different environmental conditions. Furthermore, at least the support post foot parts, the support post head parts and the beams or other components of the construction kit could have corrosion protection levels which are different from one another. For example, it is conceivable that a corrosion protection level of the support post foot part of a support post, of the base plate of a support post and / or of a lower beam module component of the beam of a support post (base region of the support post) is greater than a corrosion protection level of the support post head part of the same support post or of an upper beam module component of the beam of the same support post (superstructure of the support post), in particular if said support post is located, for example, in permanently moist vegetation or near a body of water or the like. Moreover, it is proposed that at least two of the beams of the construction kit in each case have substantially different core materials. This advantageously allows adjusting a weight and / or a bearing strength for a support post. For example, it is conceivable that the support post foot part of a support post, a base plate of a support post and / or a lower beam module component of the beam of a support post have / has a stronger / more tensile / more fracture-resistant / longer-lived, but possibly heavier, core material than the support post head part of the same support post or the upper beam module component of the beam of the same support post. If, in addition, at least two of the beams of the building set are respectively realized as profile beams with profile types that are substantially different from one another, adaption of the load-bearing properties of a support post is advantageously made possible. Moreover, adaption to local profile availabilities is advantageously enabled, as a result of which in particular transport paths can be shortened and thus resource consumption and / or CO2 emission can be reduced. Furthermore, the construction kit may comprise at least two different support post foot parts, at least two different support post head parts and / or at least two different base plates. Herein the different support post foot parts, support post head parts and / or base plates may have different sizes, different shapes, different materials or different functional elements, such as connection points to cables and / or to fastening elements / fastening bolts of the protective net installation. For example, the profile beam may have an H-profile, a T-profile, a U-profile, a Z-profile or an L-profile. Other profiles, including round, rectangular or square solid profiles or hollow profiles, are likewise conceivable. In particular, the profile type of each of the profile beams may be compatible with the standards of different jurisdictions, such as the EU, Australia, the USA or Indonesia. Furthermore, a support post is proposed, in particular produced by means of the modular support post system, preferably using the building set, the support post comprising at least one beam, in particular a profile beam, comprising at least one support post foot part and comprising at least one support post head part, wherein the beam is connected to the support post foot part and / or to the support post head part without welding. This advantageously allows simplifying production and / or mounting, in particular also on-site at a construction site. Advantageously, favorable environmental sustainability is achievable by dispensing with an energyintensive joining method such as welding. Moreover, utilization of non-weldable materials for forming a support post for a protective net installation is advantageously enabled. If furthermore the support post head part, the support post foot part and / or the base plate themselves / itself are / is produced without welding, the aforementioned advantages of non-welding can be expanded even further. In particular, the support post head part, the support post foot part and / or the base plate are / is free of sub-elements that are connected to one another by welding. In particular, the support post head part, the support post foot part and / or the base plate are / is produced merely from one or more plates, in particular metal plates, preferably from one or more bent, lasered and / or punched plates, preferably metal plates. Herein, if the support post head part, the support post foot part and / or the base plate are / is composed of several plates, in particular metal plates, these may be connected by screwing, by plugging together, by adhesive bonding and / or by clamping. It is further proposed that the support post comprises the base plate, which is - in particular without welding - connected to the support post foot part and is configured at least for a bolt-mounting of the support post in a ground. In this way, simple mounting of a support post is advantageously enabled. The base plate in particular comprises at least one support post surface that is configured to lie on the ground. The base plate in particular has a mounting interface for a mounting of the support post foot part on the base plate. The mounting interface may be realized, for example, by a bolt receptacle. In particular, the mounting interface is configured for a mounting of the support post foot part, in particular of the remaining portion of the support post, in different angular positions relative to the support post surface of the base plate, which are adjustable or depend on the respective implementation of the support post foot part. During the bolt-mounting, bolts, which are preferably realized as rock nails, are sunk into the ground and are at least clamped or screwed with the base plate. In particular, the bolts form the anchorings, in particular ground anchorings and / or rock anchorings, of the support post. Herein, if the base plate comprises a plurality of bolt positioning points for bolts that implement the bolt-mounting, with all bolt positioning points of the base plate being arranged in a line with a beam positioning point for the mounting of the beam on the base plate, a force distribution may advantageously be optimized during a force transmission between the base plate and the beam. Advantageously, in this way a torque acting on the bolts and / or on the base plate is substantially reduced. Herein, if the base plate is moreover implemented only by bent metal parts that are screwed with one another, it is advantageously possible to achieve complete non-welding of the support post and the advantages associated therewith. Advantageously, a storage space requirement for base plates can be reduced. Advantageously, a high degree of flexibility is achievable for the implementation of the base plates. In particular, the base plate is composed of merely four screws, four spacer tubes and two bent metal parts. In particular, the bent metal parts of the base plate are at least substantially mirror-symmetrical to one another. The screws are in particular guided through the spacer tubes. The spacer tubes preferably define a distance between the screwed-together bent metal parts. The spacer tubes may herein have different lengths. Advantageously, a length of the spacer tubes approximately corresponds to a diameter of the bolts / rock nails by which the base plate can be fastened to the ground. For example, the spacer tubes have a length of 50 mm, but could also be realized longer or shorter, depending on requirements. In addition, it is proposed that the beam is made at least largely of an, in particular high-tensile, steel, in particular a carbon steel, having a tensile strength of at least 380 N / mm2, preferably of at least 470 N / mm2, preferentially of at least 600 N / mm2 and particularly preferentially of 700 N / mm2. As a result, a low weight is advantageously achievable with a simultaneously high degree of stability and / or safety. In particular, the utilization of this steel as a beam material can only be ensured by the weld-free connectability of the beam to the support post foot part and / or to the support post head part, in particular to all further modular components of the modular support post system, since this, in particular high-tensile, (carbon) steel is usually not weldable or is weldable only very poorly and / or with great effort. Furthermore, it is conceivable that one or more further modular components of the modular components, in particular the support post head part, the support post foot part and / or the base plate, are / is also made of the same steel or of a steel having comparable tensile strength. Alternatively or additionally, it is proposed that the beam is at least partially made of a stainless steel. This advantageously allows achieving a particularly high degree of corrosion resistance of the support post and / or of the protective net installation with the support post, in particular if further components of the protective net installation are also made of a stainless steel. A stainless steel is in particular to mean a corrosion-resistant steel, which preferably fulfils the definition of the European standard DIN EN 10020:2000-07. In particular, the support post is realized as a lightweight support post for the use in protective net installations. Alternatively, it is proposed that the beam is made at least largely of a wood material, such as e. g. acacia wood or larch wood, or from a grass material, such as e.g. lignified bamboo. As a result, a high degree of environmental compatibility is advantageously achievable. Biodegradability at least of a portion of the support post is advantageously achievable. In particular, suitable hard woods achieve sufficient strengths for expedient utilization in many types of, in particular temporarily and / or permanently installed, protective net installations. Alternatively, it is proposed that the beam is made at least largely of a fiber-reinforced plastic (FRP=fiber-reinforced polymer). As a result, advantageous installation properties are achievable. Advantageously, a weight of a beam made of fiber-reinforced plastic is substantially lower than the weight of a beam made of steel, so that the use of heavy-duty helicopters can be advantageously reduced. Advantageously, handling in transport and in installation is substantially simplified. Moreover, fiber-reinforced plastic support posts, in particular when using suitable UV protection, can advantageously have particularly high resistance to corrosion. In particular, the fiber-reinforced plastic does not rust, in contrast to steel. Advantageously, a long service life of the support post is achievable. In particular, studies have surprisingly shown that, despite the substantially different material properties of fiber-reinforced plastic in comparison with steel, a comparable performance of the two beams can be achieved, in particular also in the case of loads / impacts in the protective net installation. In particular, according to the results of the studies, the difference in weight of the beams does not seem to be playing a significant role for their protective effect in a protective net installation. The beam is implemented by fibers impregnated in a polymer / resin, for example glass fibers, carbon fibers and / or basalt fibers. The beams made of the fiber-reinforced plastic are produced quasi as continuous elements in a pultrusion procedure. In the pultrusion procedure, the fibers are brought together, impregnated in the polymer / resin, pulled through an elongate mold, for example a profile mold, and cured. The beams manufactured in this manner can then be coated with one or more protective and / or decorative layers. In particular, the beam completely or almost completely forms that part of the support post which is arranged between the support post head part and the support post foot part of the support post. Beyond this, it is proposed that the beam is at least on a surface made of a difficult-to-ignite and / or self-extinguishing material or is coated with a difficult-to-ignite and / or self-extinguishing material. As a result, a high degree of safety and / or reliability of protective net installations, in particular also when using support posts made at least partially of FRP materials, is advantageously achievable. In particular, the beam is encompassed by at least one difficult-to-ignite sheath / outer sheath. For example, the difficult-to-ignite sheath / outer sheath is made of polyester. Alternatively or additionally, the beam may have a sheath / outer sheath made of polycarbonate, which can in particular have a self-extinguishing effect. Alternative materials, in particular plastic materials, are conceivable. The term “difficult-to-ignite” is in particular to mean comparably more difficult-to-ignite than FRP, for example FRP made of epoxy resin and glass fibers. For example, at least the surface of the beam is made of a material of the building material class B1 according to the standard DIN 4102-1:1998-05. According to this standard, standardized test pieces of tested materials, in order to fulfil the B1 criteria, must still have an average residual length of more than 15 cm after a so-called fire-shaft test and must have a temperature below the average flue gas temperature of 200 degrees Celsius. Alternatively, it is conceivable that already the synthetic resin used to produce the beam is difficult-to-ignite, like for example polyester resin. In addition, it is proposed that the beam is made at least on a surface of a UV-resistant material. In this way, a high degree of reliability and / or a long service life of protective net installations is advantageously achievable, in particular also when using support posts made at least partially of FRP materials. In particular, the beam is encompassed by at least one UV-resistant sheath / outer sheath. For example, the UV-resistant sheath / outer sheath is made of polyester. Alternatively or additionally, the beam may have a sheath / outer sheath made of vinyl ester resin, which can in particular have a UV-protective effect. The term “UV-resistant” is in particular to mean comparably more UV-resistant than FRP, for example FRP made from epoxy resin and glass fibers. Alternatively, it is conceivable that already the synthetic resin used to produce the beam is UV-resistant, like for example polyester resin or vinyl ester resin. It is further conceivable that a sheath / outer sheath is at the same time UV-resistant and difficult-to-ignite. The beam could have a mass of less than 100 kg per meter of length of the beam, preferably less than 50 kg per meter of length of the beam. In this way advantageous installation properties for protective net installations would be achievable, in particular without impairing a protective effect of the protective net installation. Preferentially, the beam and / or a beam modular component of the beam could have a mass of less than 25 kg per meter of length of the beam or of the beam modular component. This would advantageously enable manual lifting of the beam or of the beam modular component, in particular by one person, in particular while observing work protection regulations, like for example those of Swiss SUVA. Beyond this, it is proposed that the support post comprises at least one failsafe element, which is in particular made of a material different from the material of the beam and which is configured, in the event of substantial damage to the beam, like for example a breakage of the beam, to maintain a reduced beam function and / or to ensure a sufficient remaining useful height of a protective net installation / barrier that comprises the support post / is supported by the support post. As a result, a particularly high degree of safety and / or reliability of the lightweight support posts for protective net installations is achievable. In particular, the failsafe element is fastened to the beam. The failsafe element may additionally be fastened to the support post head part and / or to the support post foot part. In particular, the failsafe element extends parallel to a main extension direction of the beam. A “main extension direction” of an object is in particular to mean a direction which runs parallel to a longest edge of a smallest geometric cuboid just still completely enclosing the object. It is in particular conceivable that the support post comprises more than one failsafe element. In particular, the failsafe element is configured, in the event of a breakage of the beam, to keep the resulting fragments together. In particular, the failsafe element is arranged on a valley side or on a slope side of the installed beam. Alternatively or additionally, the failsafe element may be arranged on a side of the installed beam that is perpendicular to the valley side. In particular, if the beam is realized as a profile beam with an H-profile, the failsafe element is arranged on an inner side of the H-profile, in particular on a web of the H-profile. Alternatively, the arrangement of the failsafe element or of further failsafe elements on one of the flanges of the H-profile or on both flanges of the H-profile is also conceivable. In particular, the failsafe element is configured to prevent a complete tipping over of portions of a protective net installation in the event of a breakage of a beam. The failsafe element may be mounted on the beam, e.g. by means of gluing, by means of a screw connection or the like, and / or may be integrated in the beam, e.g. by an implementation of the beam as a multi-part component. The failsafe element is in particular realized as a rigid component, for example as a rod-shaped component. The failsafe element is in particular made of a material different from the FRP. The failsafe element is in particular made of a material that has a substantially higher elasticity than the FRP. In particular, a modulus of elasticity of the failsafe element is higher by at least 30%, preferably by at least 100%, than a modulus of elasticity of the beam. If the failsafe element is realized as a flat steel, which extends parallel to a main extension direction of the beam, which is mounted on the beam (on the outside) and / or which is integrated in the beam, a particularly high degree of safety and / or reliability of the lightweight support posts for protective net installations is advantageously achievable. In particular, the failsafe element extends over at least 80% of a total extent of the beam, preferably over at least 90% of the total extent of the beam and preferentially over the entire beam. In particular, the flat steel contacts the beam with a side having a maximum surface area. In particular, the flat steel bears flat against a surface of the beam. It is conceivable that the flat steel is connected to the support post head part and / or to the support post foot part, for example clamped, adhesively bonded or plugged together with the support post head part and / or the support post foot part. If moreover the flat steel is implemented by a spring steel, a particularly high breaking resistance and / or a particularly good safety effect is advantageously achievable. In particular, the spring steel of the flat steel has a yield strength of at least 800 N / mm2, preferably at least 1000 N / mm2 (with a tensile strength of 800 to 2000 N / mm2). In particular, a ratio of yield strength to tensile strength of the spring steel of the flat steel is greater than 80%. If, in particular in addition to the beam, the support post foot part, the support post head part and / or the bent metal parts of the base plate are / is made of an, in particular high-tensile, steel, in particular a carbon steel, preferably having a tensile strength of at least 380 N / mm2, preferably of at least 470 N / mm2, preferentially of at least 600 N / mm2 and particularly preferentially of 700 N / mm2, a low total weight of the support post is advantageously achievable with a simultaneously high degree of stability and / or safety. In particular, the utilization of this steel as a material for the support post foot part and / or the support post head part can only be ensured by the weld-free connectability of the beam to the support post foot part and / or to the support post head part, in particular to all further modular components of the modular support post system, since this, in particular high-tensile, (carbon) steel is usually not weldable or is weldable only very poorly and / or with great effort. In addition, it is proposed that the support post foot part comprises at least one integrated anti-tilt-back component, in particular an integrated construction anti-tilt-back component. As a result, a high degree of safety is advantageously achievable. Moreover, one-person mounting of the support post is advantageously enabled. As a result, it is advantageously possible to dispense with the need to provide restraining cables during the mounting of a support post, in particular since the support post can already stand on its own in the base plate due to the integrated anti-tilt-back component. As a result, mounting efficiency is advantageously improved, and in particular saving of resources (e. g. fewer helicopter hours) is achievable. In particular, in order to create the securing effect against a tilt-back of the support post, in particular during the construction of the support post, the anti-tilt-back component of the support post foot part interacts with a further anti-tilt-back component of the support post, which is realized as a bolt that can be mounted on the base plate. The further anti-tilt-back component herein preferably serves as an abutment for the anti-tilt-back component of the support post foot part, by which a relative movement between beam / support post foot part and base plate is limited and / or prevented. In particular, the position of the further anti-tilt-back component in the base plate is variable, in particular for an adjustment of a maximally permissible tilt angle. For example, the base plate may comprise several (bolt) receiving recesses, which are spaced apart from one another and are configured for a mounting of the further anti-tilt-back component on the base plate. In particular, the anti-tilt-back component that is integrated in the support post foot part is realized differently from and / or in addition to the modular component of the modular support post system which also forms an antitilt-back safeguard. Preferably, the anti-tilt-back component that is integrated in the support post foot part is configured for an initial anti-tilt-back securing during the construction of the support post, while the modular component of the modular support post system that forms the anti-tilt-back safeguard is configured for a permanent anti-tilt-back securing of the fully-installed support post. However, it is also conceivable that the additional anti-tilt-back safeguard that is realized by the modular component is dispensed with and only the integrated anti-tilt-back safeguard is provided for the permanent operation. It is further proposed that the support post foot part comprises at least one integrated or mounted-on centering aid for a centering of the support post foot part during a mounting on a base plate of the support post. This advantageously allows simplifying a mounting of a support post. As a result, mounting efficiency is advantageously improved, and in particular saving of resources (e. g. fewer helicopter hours) is achievable. Moreover, safety for the fitter, in particular the fitter's fingers, can be increased. The centering aid of the support post foot part interacts in particular with a portion of the base plate, in particular with an outer contour of the mounting interface, in order to achieve the centering of the support post foot part relative to the base plate. In particular, the centering aid is implemented as one or several elements, for example screws, bolts or the like, which protrude laterally beyond the support post foot part and which on their circumferential surfaces come into contact with the contour of the mounting interface of the base plate, said contour then guiding the support post foot part into the correct centered position by its contour profile. Furthermore, a protective net installation comprising one or several support posts and comprising at least one protective netting, in particular a high-tensile steel wire netting, preferably a high-tensile steel wire ring netting, is proposed. This allows obtaining advantageous installation properties, in particular while maintaining a high, in particular at least constant, protective effect. In particular, the protective netting is realized as a wire netting made of wires, preferably of high-tensile steel wires having tensile strengths above 1000 N / mm2. The protective netting may herein be realized as a mesh wire netting with rectangular or rhombic mesh shapes, as a steel wire ring netting with rings which engage into one another or are shackled with one another, as a so-called omega netting having helical cable strands which are pre-curved in a wave-shaped manner and are braided with one another, as a hexagonal netting or as a netting having a further mesh shape, or as a combination of the aforementioned nettings. Protective nettings made of materials other than high-tensile steel are of course also conceivable. In particular, the protective net installation is realized as the net-and-cable construction in which the protective netting is suspended and possibly guided on cables stretched between the support posts. Furthermore, a method is proposed for producing the support post by means of the modular support post system, preferably from the construction kit. As a result, a high degree of efficiency is advantageously achievable. Advantageously, a production effort can be reduced, in particular as it is possible to switch from project-related individual production to series production of modular components. This advantageously allows saving costs, production time and / or resources. Furthermore, a method is proposed for producing the support post with the beam which is made at least largely of a fiber-reinforced plastic, in particular for a protective net installation comprising said support post, the method including the method steps of: a) producing a profile rod from a fiber-reinforced plastic by pultrusion, in particular as a continuous part, b) cutting the profile rod to length, in particular to a respectively required length, in order to produce the beam that is realized as a profile beam, c) providing a support post head part, which is in particular made of steel, d) fixing the support post head part to the beam without welding, for example by means of a connection element, by adhesive bonding and / or by a press fit, e) providing a support post foot part, which is in particular made of steel, f) fixing the support post foot part to the beam without welding, for example by means of a connection element, by adhesive bonding and / or by a press fit, and g) optionally fixing the base plate to the support post foot part without welding. In this way, a particularly lightweight support post can advantageously be produced, which advantageously presents an at least equivalent performance in comparison with a purely steel support post. The modular support post system according to the invention, the construction kit according to the invention, the support post according to the invention, the protective net installation according to the invention and the methods according to the invention shall herein not be limited to the above-described application and implementation. In particular, in order to fulfil a functionality described here, the modular support post system according to the invention, the construction kit according to the invention, the support post according to the invention, the protective net installation according to the invention and the methods according to the invention may comprise a number of individual elements, components and units that deviates from a number given here.

Description of the exemplary embodiments Figure 1 shows a schematic perspective view of a protective net installation 12. In the case shown, the protective net installation 12 is embodied as a rockfall barrier configured for catching impact bodies 96, for example rock boulders. Alternative types of protective net installations 12 are conceivable. The protective net installation 12 comprises a protective netting 80. In the case shown, the protective netting 80 is realized as a steel wire ring netting. In the case shown, the protective netting 80 is embodied as a high-tensile steel wire ring netting. Alternative customary types of protective nettings 80 are conceivable. Figure 1 shows the protective net installation 12 by way of example immediately after an impact of the impact body 96. The impact body 96 was caught by the rockfall barrier and is hanging in the protective netting 80. During the capturing process, the kinetic energy of the impact body 96 was completely absorbed by the protective net installation 12. In the case shown, the protective net installation 12 comprises four support posts 10. The support posts 10 are anchored in a ground 52 which forms a rock wall. The protective net installation 12 comprises cables 98. The cables 98 are at least partly anchored at the rock wall. The cables 98 are fastened to the support posts 10, in particular to support post head parts 18 of the support posts 10. The cables 98 are partly threaded in the protective netting 80. The protective netting 80 is fastened, in particular suspended, at the rock wall and at the support posts 10 by means of the cables 98. The protective net installation 12 comprises upper load-bearing cables 100. The support posts 10 in each case comprise support post head parts 18. The upper load-bearing cables 100 in each case extend between support post head parts 18 of neighboring support posts 10. The upper load-bearing cables 100 are fastened to the support post head parts 18 of the support posts 10. The protective net installation 12 comprises lower loadbearing cables 102. The support posts 10 in each case comprise base plates 50. The lower load-bearing cables 102 in each case extend between base plates 50 of neighboring support posts 10. The lower load-bearing cables 102 are fastened to the base plates 50 of the support posts 10. The protective net installation 12, which is shown by way of example in figure 1, further comprises side guying cables 174 and restraining cables 176. The load-bearing cables 100, 102 are realized as steel cables, which are in particular made of high-tensile steel wire. Figure 2 shows a schematic perspective overall view of an individual support post 10 of the protective net installation 12. In figure 3a a schematic perspective exploded view of a modular support post system is shown, wherein a portion of a beam 14 of the support post 10 is omitted for the sake of clarity. The modular support post system is configured for producing the support post 10. The modular support post system comprises modular components 20, 22, 24, 28, 32, 104, 142. The modular components 20, 22, 24, 28, 32, 104, 142 are in each case prefabricated. The support post 10 is produced by a combination of modular components 20, 22, 24, 28, 32, 104, 142. The support post 10 comprises the beam 14. The beam 14 is realized as a profile beam. The beam 14 forms a modular component 104 of the modular support post system. In the example shown in figure 3a, the modular component 104 that is a beam 14 comprises two separately realized beam modular components 38, 40. The beam 14 has a longitudinal direction 36. The longitudinal direction 36 runs parallel to a main extension direction 74 of the beam 14. The beam modular components 38, 40 can be joined / are joined in the longitudinal direction 36 of the beam 14. Alternatively, it is conceivable that the beam 14 is realized just as a single monolithic beam modular component or that the beam 14 is composed of more than two beam modular components. In the exemplary embodiment shown in figure 3a, the beam modular components 38, 40 are respectively realized with the same material thicknesses, outer diameters and profile types. Alternatively, however, the beam modular components may have different material thicknesses, different maximum outer diameters and / or different profile types, see in this regard in particular the construction kit 42 shown in figure 4. The beam 14 is produced without welding. The beam modular components 38, 40 are connected to one another without welding. In the exemplary embodiment shown in figure 3a, the beam modular components 38, 40 are inserted into one another. The beam 14 is produced from a non-weldable or difficult-to-weld material. The beam 14 shown in the exemplary embodiment of figure 3a is made of a steel, in particular a carbon steel. The steel of the beam 14 has a tensile strength of at least 420 N / mm2. Alternatively or additionally, the beam 14 could be made at least partly (e.g. on an outer surface) or completely of a stainless steel. However, it is also conceivable that the beam 14 is produced from a standard steel, e.g. a structural steel, which could also be weldable. Alternative beam materials are conceivable. For example, in figure 5 an exemplary embodiment is shown in which the beam 14 is made at least largely of a fiber-reinforced plastic (FRP=fiber-reinforced polymer). Moreover, instead of being made of a metal, the beam 14 could be made at least largely of a wood material, like for example acacia wood or larch wood, or of a grass material, like for example lignified bamboo. The support post 10 comprises a support post foot part 16. The support post foot part 16 is realized as a modular component 20 of the modular support post system. The support post foot part 16 is realized as a modular component 20 that can be fixed to the modular component 104 which is a beam 14. In the example shown in figure 3a, the fixing of the modular components 20, 104, which are the beam 14 and the support post foot part 16, is brought about by screwing, using screw elements that are respectively guided through holes in the beam 14 and in the support post foot part 16. The support post foot part 16 is mounted on the beam 14 without welding. The support post foot part 16 itself is produced without welding. The support post foot part 16 is made of a steel, in particular a carbon steel, having a tensile strength of at least 420 N / mm2. Alternatively or additionally, the support post foot part 16 may be made of a stainless steel. The support post foot part 16 is connected to the beam 14 in such a way that it is non-destructively exchangeable. The support post foot part 16 is connected to the beam 14 in such a way that it is non-destructively detachable. The support post foot part 16 is realized differently and / or separately from the base plate 50 of the support post 10. The support post foot part 16 implements an adapter part for a connection of the beam 14 to the base plate 50. The base plate 50 has a mounting interface 88 for a mounting of the support post foot part 16. The mounting interface 88 of the base plate 50 is realized as a bolt receiving recess 86 for a mounting bolt 106. The support post foot part 16 also has a mounting interface 108. The mounting interface 108 of the support post foot part 16 is realized as a through hole. During the mounting of the support post foot part 16 on the base plate 50, the mounting bolt 106 is pushed through the through hole of the mounting interface 108 of the support post foot part 16 and through the bolt receiving recess 86 of the mounting interface 88 of the base plate 50 and is secured there. This type of bolt-mounting allows a pivoting of the support post foot part 16 with respect to the base plate 50. The support post 10 comprises an anti-tilt-back safeguard 136. The support post foot part 16 comprises an anti-tilt-back component 76 of the anti-tilt-back safeguard 136. The anti-tilt-back safeguard 136 of the support post foot part 16 implements a construction anti-tilt-back safeguard. The anti-tilt-back component 76 of the support post foot part 16 is realized so as to be integrated in the support post foot part 16. The anti-tilt-back component 76 of the support post foot part 16 is realized as an (integral) longitudinal extension of the support post foot part 16. The base plate 50 comprises a further anti-tilt-back component 110 of the anti-tilt-back safeguard 136. The further anti-tilt-back component 110 of the base plate 50 is realized as a bolt receiving recess of the base plate 50. Viewed in the setting-up direction 116 of the support post 10, the further anti-tilt-back component 110 of the base plate 50 is arranged below the mounting interface 108 of the base plate 50. The support post 10 comprises a second further anti-tilt-back component 112 of the anti-tilt-back safeguard 136. The second further anti-tilt-back component 112 of the support post 10 is realized as a bolt. For an activation of the anti-tilt-back safeguard 136, the second further anti-tilt-back component 112 of the support post 10 is configured to be pushed into the bolt receiving recess of the further anti-tilt-back component 110 of the base plate 50 and to be fixed there. As a result, if a support post foot part 16 is mounted on the base plate 50, the second further antitilt-back component 112 of the support post 10 is arranged relative to the anti-tilt-back component 76 of the support post foot part 16 in such a manner that the antitilt-back component 76 of the support post foot part 16 abuts against the second further anti-tilt-back component 112 of the support post 10 and thus a rotation of the support post foot part 16 relative to the base plate 50 is limited, i.e. in particular a tilting back of the beam 14 that is mounted on the support post foot part 16 is prevented. The base plate 50 may comprise a plurality of further anti-tilt-back components 110, such that a maximum tilt angle can be set and / or that a secured tilt-back direction can be defined. The support post foot part 16 comprises a centering aid 78. The centering aid 78 is configured for a centering of the support post foot part 16 during the mounting of the support post foot part 16 on the base plate 50. In the exemplary embodiment shown in figure 3a, the centering aid 78 is mounted to the support post foot part 16. Alternatively, the centering aid 78 could also be integrated in the support post foot part 16. In the case shown, the centering aid 78 is implemented by two screw bolts which penetrate the support post foot part 16 and are fixed on the support post foot part 16. The base plate 50 has a centering contour 114. Viewed in the setting-up direction 116 of the support post 10, the centering contour 114 is arranged above the mounting interface 108 of the base plate 50. The screw bolts which form the centering aid 78 contact the centering contour 114 with their circumferential surfaces. As a result of the screw bolts that form the centering aid 78 passing over the centering contour 114, the support post foot part 16 is pushed (automatically / with the assistance of gravity) into a centered position, in which preferably the mounting interfaces 88, 108 have optimum overlap and thus simple insertion of the mounting bolt 106 is enabled. The support post foot part 16 has a beam interface 118. The beam interface 118 of the support post foot part 16 is configured for the weld-free mounting of the support post foot part 16 to the beam 14. The beam 14 has a support post foot part interface 120. The support post foot part interface 120 is configured for the weld-free mounting of the beam 14 to the support post foot part 16. In the case shown in figure 3a, the support post foot part interface 120 and the beam interface 118 of the support post foot part 16 are connected by screws which are inserted through overlapping holes of the beam 14 and of the support post foot part 16. The beam interface 118 of the support post foot part 16 is arranged at a longitudinal end of the support post foot part 16 that is situated opposite the longitudinal end at which the anti-tilt-back component 76 of the support post foot part 16 is situated. The support post 10 comprises a support post head part 18. The support post head part 18 is realized as a modular component 22 of the modular support post system. The support post head part 18 is realized as a modular component 22 that can be fixed to the modular component 104 which is a beam 14. In the example shown in figure 3a, the fixing of the modular components 22, 104, which are the beam 14 and the support post head part 18, is brought about by screwing, using screw elements which are respectively guided through holes in the beam 14 and in the support post head part 18. The support post head part 18 is mounted on the beam 14 without welding. The support post head part 18 itself is produced without welding. The support post head part 18 is made of a steel, in particular a carbon steel, having a tensile strength of at least 420 N / mm2. Alternatively or additionally, the support post head part 18 may be made of a stainless steel. The support post head part 18 is connected to the beam 14 in such a way that it is non-destructively exchangeable. The support post head part 18 is connected to the beam 14 in such a way that it is non-destructively detachable. The support post head part 18 comprises cable guides 122 and / or mounting points for shackles 124 or the like. The support post head part 18 has a beam interface 126. The beam interface 126 of the support post head part 18 is configured for the weld-free mounting of the support post head part 18 to the beam 14. The beam 14 has a support post head part interface 128. The support post head part interface 128 is configured for the weld-free mounting of the beam 14 to the support post head part 18. In the case shown in figure 3a, the support post head part interface 128 and the beam interface 126 of the support post head part 18 are connected by screws inserted through overlapping holes of the beam 14 and of the support post head part 18. The support post 10 comprises a climbing aid 26. The support post 10 comprises a plurality of climbing aids 26 wherein, however, only one climbing aid is provided with a reference numeral in figure 3a and is described in detail. The climbing aids 26 are realized so as to be at least substantially identical to one another. The climbing aid 26 is realized as a further modular component 24 of the modular support post system. The climbing aid 26 is configured for assisting a person (see figure 1) when climbing up the support post 10. The climbing aid 26 is attached to a front side 130 of the support post 10. However, an alternative arrangement of the climbing aid 26 would also be conceivable. The climbing aid 26 is mounted on the beam 14 without welding. The beam 14 has a mounting interface 132 for the mounting of the climbing aid 26. The climbing aid 26 is realized substantially as a (U-shaped) bent rod, in particular metal rod. The mounting interface 132 for the mounting of the climbing aid 26 has holes into which ends of the rod that is bent to form the climbing aid 26 can be inserted. At the ends of the bent rod, the climbing aid 26 respectively comprises a securing element 134, which secures the climbing aid 26 against being detached from the beam 14. The securing element 134 may be realized as an angled end region or as a securing bolt or securing wedge that is inserted through an end of the bent rod of the climbing aid 26. Alternatively, the climbing aid 26 may be implemented by steel straps which are wound and tensioned around the beam 14. The support post 10 comprises an anti-tilt-back safeguard 30. The anti-tilt-back safeguard 30 is realized as a further modular component 28 of the modular support post system. The anti-tilt-back safeguard 30 is realized as a permanent anti-tilt-back safeguard. The anti-tilt-back safeguard 30 may be provided alternatively or additionally to the anti-tilt-back safeguard 136 that is partially integrated in the support post foot part 16. It is conceivable that the anti-tilt-back safeguard 136, which is partially integrated in the support post foot part 16, is used during the construction of the support post 10 and the anti-tilt-back safeguard 30, which forms the modular component 28, secures the support post 10 after assembly. However, it is also conceivable that one of the two anti-tilt-back safeguards 30, 136 is completely dispensed with. The anti-tilt-back safeguard 30 comprises a cable construction. The anti-tilt-back safeguard 30 is mounted on the beam 14 without welding. The anti-tilt-back safeguard 30 is mounted on the base plate 50 without welding. In addition, it is conceivable that the anti-tilt-back safeguard 30 is mounted on the beam 14 without holes (see the component of the construction kit 42 from figure 4 with the reference numeral 30‘). However, in the case shown in figure 3a, the anti-tilt-back safeguard 30 is screwed onto the beam 14 via a mounting interface 138. The support post 10 comprises a sensor module 34. The sensor module 34 is realized as a further modular component 32 of the modular support post system. The sensor module 34 may comprise a pressure sensor, a tension sensor, a corrosion sensor and / or the like. The sensor module 34 may be configured for a monitoring of impact events in the protective net installation 12, of aging or wear of the protective net installation 12 or of environmental parameters of the protective net installation 12. The support post 10 has a sensor module interface 140. The sensor module interface 140 is arranged on the support post head part 18. Alternatively or additionally, the beam 14, the support post foot part 16 or the base plate 50 could also have a sensor module interface 140. The sensor module 34 could be realized in the manner described in the German patent application with the publication number DE 10 2020 122 861 A1. The base plate 50 is realized as a further modular component 142 of the modular support post system. The base plate 50 is connected to the support post foot part 16 without welding. The base plate 50 is configured for a bolt-mounting of the support post 10 in the ground 52. The base plate 50 has a plurality of bolt positioning points 54, 56, 144 for bolts 58, 60 that implement the bolt-mounting. In the exemplary embodiment shown by way of example in figure 3a, the base plate 50 has exactly three bolt positioning points 54, 56, 144. In the example shown in figure 3a, only two bolt positioning points 54, 56 are also occupied by bolts 58, 60. The third bolt positioning point 144, which is configured for an oblique mounting of a further bolt, remains free in this case. The base plate 50 has a beam positioning point 64 for mounting the beam 14 on the base plate 50. The beam positioning point 64 is defined / predetermined by the mounting interface 88 of the base plate 50. All bolt positioning points 54, 56, 144 of the base plate 50 are arranged in a line 62 with the beam positioning point 64 of the base plate 50. The base plate 50 itself is produced without welding. The base plate 50 is realized only by bent metal parts 66, 68 which are screwed with one another. The base plate 50 comprises exactly two bent metal parts 66, 68. The bent metal parts 66, 68 are realized so as to be mirror-symmetrical to one another. The bent metal parts 66, 68 are connected to one another by screws 146. The base plate 50 forms one or several cable guide regions 148. Figure 3b shows the base plate with an alternative arrangement of the bolts 58, 60. One of the two bolts 58 is positioned obliquely relative to the other bolt 60. The base plate 50 comprises an insert part 180. The insert part 180 forms an oblique bolt support for the bolt 58.

Preferably, the obliquely positioned bolt 60 is used if it is not possible to create an underlying concrete foundation. However, it is also conceivable that the obliquely positioned bolt 60 is nevertheless used, even if there are concrete foundations. Figure 4 schematically shows a construction kit 42 for the modular support post system for producing the support posts 10 which are configured for the use in different (types, sizes, etc.) protective net installations 12. The construction kit 42 comprises building sets for a very large number of support posts 10. The construction kit 42 comprises a plurality of different beams 14, 14', 14", 14'", 14’"". The different beams 14, 14', 14", 14'", 14'"" of the construction kit 42 have different lengths, different profile types and / or different transverse extents. In addition, the construction kit 42 may comprise different beam module components 38, 40 which in turn can be assembled to form different further beams 14.

The different anti-tilt-back safeguards 30, 30' may have different strengths or different mounting interfaces 138 for the mounting on the beam 14, etc. The anti-tilt-back safeguard 30', which is fastened without holes, is secured / fastened to the beam 14 by means of a clamp 44. In order to create the holding, the clamp 44 engages, for example, on one of the flanges 152, 154 of a profile of a beam 14 that is realized as a profile beam. In order to create the holding, the clamp 44 engages around the flange 152, 154 of the profile of the beam 14. Alternative hole-free fastenings of the anti-tilt-back safeguard 30, 30' on the beam 14, such as steel straps that are wrapped around the beam 14 or screwing with the beam 14 / clamping with the beam 14 (for example in the manner of a screw clamp or the like), are conceivable.

The different support posts 10 are intended for different sizes, different energy classes and / or different types of protective net installations 12, in particular with different service life requirements or with different projected load situations / load types. In figure 5 a section through a beam 14 of an exemplary support post 10, which is produced by means of the modular support post system, in particular from the construction kit 42, is shown schematically. The beam 14 of the exemplary embodiment of figure 5 is realized by way of example as a beam 14 that is made at least largely of a fiber-reinforced plastic (FRP=fiber-reinforced polymer). A beam 14 realized in this manner advantageously has a mass of less than 100 kg per meter of length of the beam 14. The beam 14 forms an H-profile / I-profile. The beam 14 comprises a web 150. The beam 14 comprises a first flange 152. The beam 14 comprises a second flange 154, which is situated opposite the first flange 152. The beam 14 is at least on a surface 70 made of a difficult-to-ignite material. The beam 14 is at least on the surface 70 made of a self-extinguishing material. Alternatively, it is also conceivable that the entire beam 14 is made of a difficult-to-ignite and / or self-extinguishing material, in particular the fiber-reinforced plastic. The beam 14 is at least on the surface 70 made of a UV-resistant material. Alternatively, it is also conceivable that the entire beam 14 is made of a UV-resistant material, in particular fiber-reinforced polyester resin or vinyl ester resin. The beam 14, which is shown in figure 5 by way of example, has a core 156 and several sheathing layers 158, 160, 162. In the example shown, the core 156 of the beam 14 is made of a glass roving impregnated in a polymer resin. Alternatively, basalt rovings, aramid rovings, carbon rovings etc. are also conceivable. In the example shown, a first sheathing layer 158 of the beam 14 is implemented by a glass fiber mat impregnated in a polymer resin. Alternatively, basalt fiber mats, aramid fiber mats, carbon fiber mats etc. are also conceivable. In the example shown, a second sheathing layer 160 of the beam 14 is implemented by a so-called surfacing veil. The surfacing veil is in particular made of non-woven, evenly distributed glass fiber strands which are impregnated in a polymer resin, and serves to reinforce the surface of a component and to create a smooth, resin-rich and durable surface. In the example shown, a third sheathing layer 162 of the beam 14 is implemented by a coating of a self-extinguishing and UV-resistant material, e.g. polyester. The support post 10 comprises a failsafe element 72 (not shown in the view of the beam 14 of figure 3a). The failsafe element 72 is configured, in the event of substantial damage to the beam 14, to maintain a reduced beam function. The failsafe element 72 is configured, in the event of substantial damage to the beam 14, to ensure a sufficient remaining useful height of the protective net installation 12 comprising the support post 10. The failsafe element 72 is arranged so as to extend parallel to a main extension direction 74 of the beam 14. The failsafe element 72 is mounted on the beam 14 (e.g. by screws). Alternatively, the failsafe element 72 may also be partially or completely integrated in the beam 14, e.g. in the core 156 of the beam 14. The failsafe element 72 is realized as a flat steel. The flat steel is implemented by a spring steel. The failsafe element 72 extends over more than 80%, preferably over more than 90%, of a distance between the support post foot part 16 and the support post head part 18 of the support post 10. Figure 6 shows a schematic flow chart for a method for producing the support post 10 for protective net installations 12. In the method, the support post 10 can be produced using the modular support post system. In the method, the support post 10 can be produced using the construction kit 42. In at least one method step 82, a profile rod is produced by pultrusion from a fiber-reinforced plastic. The profile rod is produced as a continuous element in a continuous process. The produced profile rod may have one of the profile shapes mentioned above. In at least one further method step 84, the profile rod is cut to a respectively required length. Herein the desired beam 14 for the respective support post 10 is produced. Alternatively, in at least one method step 46, the desired beam 14 may be produced by a joining of several beam module components 38, 40. In a further, alternative method step 48, the beam 14 could also be produced from a material different than the fiber-reinforced plastic, for example from a high-tensile steel, from a stainless steel, from a wood material or from a grass material etc. In at least one further method step 90, the respectively fitting support post head part 18 is provided. In at least one further method step 92, the support post head part 18 is fixed to the beam 14 without welding. In at least one further method step 92, a support post foot part 16 is provided. In at least one further method step 94, the support post foot part 16 is fixed to the beam 14 without welding. In at least one further method step 164, a base plate 50 is provided. In at least one further method step 166, the base plate 50 is fixed to the support post foot part 16 without welding. In at least one further method step 168, the failsafe element 72 is fastened to the beam 14. Alternatively or additionally, the failsafe element 72 may be fastened to the support post head part 18, the support post foot part 16 and / or the base plate 50. Moreover, the failsafe element 72 may alternatively already have been integrated in the beam 14 during the pultrusion of the method step 82. In at least one further method step 170, the support post 10 is installed in a protective net installation 12. 5 Figure 7 shows a schematic flow chart of a failsafe method for support posts 10 of protective net installations 12 for preventing support post breakage. In at least one method step 172, at least two fragments of support posts 10 are held together by the failsafe element 72, so that a reduced beam function of the broken support post 10 is maintained and / or so that a sufficient remaining useful height of the 10 protective net installation 12 is ensured. In at least one further method step 178, a modular component 20, 22, 24, 28, 32, 104, 142 that was damaged, for example by an impact, is exchanged, preferably at the location of the protective net installation 12. For this purpose, the damaged modular component 20, 22, 24, 28, 32, 104, 142 is removed from the support post 10 without damaging undamaged 15 modular components 20, 22, 24, 28, 32, 104, 142, and is replaced by a new, undamaged modular component 20, 22, 24, 28, 32, 104, 142 having the same function as the damaged modular component 20, 22, 24, 28, 32, 104, 142.
