Description

[0001] Design and production process of a support structure as a building element or panel element for structures such as buildings, BI PV and floating photovoltaic systems (FPV), and much more.

[0002] The invention relates to the field of building elements such as panel elements or beam elements, e.g. for a house wall, carport roof, house ceiling, soundproof wall, house roof, floating photovoltaic modules and their manufacturing processes. In particular, the invention relates to a support structure according to the preamble of claim 1, specifically - but not only - in the above-mentioned fields. The invention also relates to panel elements or other building elements produced with such a support structure, such as walls, wall elements, roofing, roof elements, roofs, flat roofs, for example for the construction of houses but also for soundproof walls and for all types of buildings and facilities such as bus stops, post and beam constructions, garages, carports, as well as photovoltaics integrated into the special building, thermal solar elements and floating photovoltaic modules or systems and their floating elements.The invention also relates to corresponding methods for producing such support structures or components comprising them.

[0003] Wall elements are traditionally constructed using bricks, Ytong blocks or similar mineral stones, clay, concrete or timber. However, modular construction or lightweight construction is becoming increasingly popular in prefabricated house construction as well as in high-rise building. Here, processed wood in the form of wooden beams, slats and boards is used as the base support, to which corresponding wall elements such as insulation panels are then added. Overall, these materials are relatively expensive and even light wood species such as spruce have a high bulk density compared to their load-bearing capacity and therefore weight. Final assembly is also relatively time-consuming, as appropriate machinery with corresponding lifting capacity is required for the assembly of the relatively heavy building components. The base supports are also often sawn to size first, e.g. with bevel cuts, so that the supports can be easily connected to one another.

[0004] Carports are often offered as kits consisting of a support structure made of individual pre-cut wooden elements, or steel or aluminum elements. Lightweight, highly processed wooden elements often require additional maintenance and are not as durable. Heavy steel structures, on the other hand, often cannot be assembled without heavy machinery.

[0005] The construction is therefore time-consuming and, especially in connection with photovoltaics and electric charging stations, often very technically demanding.

[0006] BI PV structures, such as those used for soundproof walls or roofing, often consist of aluminum supports mounted on standard soundproof walls. Installation is time-consuming and complex, and therefore expensive.

[0007] Floating photovoltaic systems or modules usually consist of a floating plastic element, a so-called floater, and a support system, usually made of stainless steel or aluminum for the photovoltaic system.

[0008] Examples can be found in DE102006000864A1, DE102009051051 A1, etc. The installation of such classic wall elements often incurs high costs and, depending on the material, they are difficult to reuse or recycle.

[0009] In WO2023 / 194792, bamboo is used as a structure, whereby the structure is enclosed by a solid / filler in a tank to form a smooth and closed surface, which means more weight and material requirements.

[0010] The invention aims to eliminate such disadvantages. Specifically, the objective is to provide improved components or panel elements—in particular, the support structure therefor—that can be reused for various purposes. Synergy effects in production should also be enabled. These components should be simpler and more cost-effective to manufacture and assemble, and / or exhibit higher load-bearing capacity than the state of the art while being lighter in weight. Assembly costs should also be significantly reduced, and the products should be easier to recycle. Furthermore, the CO2 footprint should be reduced, primarily through reduced preprocessing effort.

[0011] This is achieved by the present invention. One aspect is the standardization of naturally grown bamboo. Bamboo, or other round trees, grows back quickly. Among other things, the invention overcomes the problem that such naturally grown round sticks do not have a standardized shape. Diameter, straightness, etc. vary not only between individual bamboo sticks, but also within a single stick. One aim is to provide a bamboo support structure that is as light as possible, close to nature and requires little processing, with connecting elements and frames made of plastic, wood and / or metal. These can also be easily recycled, for example using a bamboo-metal connection, which is lighter, has lower CO2 emissions and is cheaper than a support structure made entirely of metal.

[0012] In particular, with sleeve-forming connecting elements, which serve as standardization and support elements, cost and weight savings are achieved, as well as advantages during assembly.

[0013] The invention specifically relates to a support structure for a composite building element or such a building element, which may specifically be a panel element according to the invention. Composite building element here refers to the fact that it is constructed from several different components, each of which fulfills a specific functional task and which together, in synergy, shape the special properties of the building element. Support structures or building elements according to the invention can in particular be designed to construct a roof element or wall element for a structure or building such as a garage, house, soundproof wall, bus stop, house roof, roofing, carport, in particular as a photovoltaic carport, open-space PV system or BI PV as well as a floating photovoltaic module (FPV) or FPV system, etc. According to the invention, the support structure orThe structural element consists at least of: several naturally grown round rods, in particular bamboo rods, which are arranged with connector elements for creating (or for creating or providing) a fixation or connection at several points on the naturally grown round rods. Preferably rigid or solid or stiff, in particular made of plastic, metal, or wood.

[0014] The connecting elements form sleeves, for example in the form of holes, bores, or cavities, each of which encloses at least one of the naturally grown round rods. In particular, each sleeve comprises a single round rod or a bundle of several round rods to increase stability or to improve the material utilization of the different natural growths by combining round rods of different thicknesses.Specifically, these are designed so that the naturally grown round rods pass through these connecting elements. In other words, in one embodiment, the connecting elements serve to give the individual bamboo a uniform shape and circumference at the connecting points, so that they have a standardizable shape at the connecting points. These connecting points serve to provide an assembly, fastening, and support surface, for example for commercially available layered elements such as panel elements, photovoltaics, or solar modules, as well as to form assembly structures to which additional elements such as metal elements, steel connections, or even a separate support structure can be connected. The sleeve has a larger inner diameter than the largest outer diameter of the bamboo rods, so that it is loose in the sleeve when inserted.

[0015] The naturally grown round rods are then secured in the sleeves with a fixing agent, preferably at at least one or both ends of the naturally grown round rods and / or along them. The connector elements are designed and arranged in such a way that they provide a support surface for external components – preferably in a flat plane.

[0016] Preferably, the support surface is covered by a cover layer, in particular in the form of a plate or a film, which can be or is fastened to the connector elements of the support structure.

[0017] The support structure is preferably surrounded by a frame as the main girder of the support structure, which frame preferably encloses the support structure completely along its outer contour. Such a frame is particularly designed as an L-profile or U-profile shape or with a frame structure made of wall elements from house construction, which may have sleeves / connector elements. In some embodiments, the frame is on at least one side, but preferably enclosing it along the circumference of the support structure. The frame is designed with connector elements which receive the ends of the naturally grown round bars, in particular wherein the naturally grown round bars are arranged essentially flat, preferably in one plane. In particular wherein a frame is on at least one of the open areas or areas enclosed by it.The sides can be spanned by the cover layer or an external component, in particular in the form of a film or plate, which can be fastened to the frame and / or the connector elements of the support structure. The frame and / or the connector elements can be designed and arranged such that they form a flat structure toward the plate. Preferably, the frame can be designed with openings that contain connector elements or are formed by the support structure.

[0018] Preferably, an intermediate space between the sleeve and the naturally grown round rod enclosed by it is filled with an introduced fixing agent. For example, a hardening filler material which in particular changes from a liquid or plastic to a solid or elastic state. In another embodiment, the fixing agent can also be in the form of screws, nails, etc. In particular, the fixing agent can be a filler material such as adhesive, epoxy resin, silicone, hot melt glue, glue or liquefied plastic, cement, polymer concrete or resin, preferably wherein this is introduced or injected into the connector element in liquid form and hardens there. For this purpose, the connector elements can be designed with an injection channel and / or with a channel for distributing the fixing agent.

[0019] Preferably, the naturally grown round bars are arranged in a grid or honeycomb arrangement which intersect at nodes, wherein at least a subset of these nodes a connection is formed between the intersecting naturally grown round bars by means of the connecting elements.

[0020] Preferably, the naturally grown round rods are bamboo sticks or bamboo tubes or wooden branches, or a renewable material that is primarily based on bamboo DNA or is bamboo.

[0021] Preferably, the sleeves each enclose the naturally grown round rod circumferentially, wherein the sleeve is designed such that the naturally grown round rod can be loosely inserted into the sleeve without the filling material, i.e. in particular with a gap of at least 2 mm to approximately 2 cm, and preferably the filling material encloses the round rod in the sleeve circumferentially.

[0022] Preferably, at least one of the connector elements is formed from at least two parts, each forming a sleeve and connected or connectable to one another, in particular wherein the parts are rotatable relative to one another and / or the parts are designed to snap together. Preferably, the parts are identical parts. Alternatively or additionally, there are also embodiments in which the connector elements integrally form at least two sleeves.

[0023] Preferably, the connector element is designed in two parts or can be folded open such that its sleeve can be placed around the naturally grown round rod in an open state and then closed comprehensively around the naturally grown round rod so that it is enclosed by the sleeve. This, in addition to a solid, one-piece embodiment. In other words, the connector element can also be designed such that the naturally grown round rod does not have to be pushed through, but rather an opened connector can be snapped open from the side and then closed, in particular not in a form-fitting or force-fitting manner. Preferably, the support structure or the component or plate element is provided in its individual parts or in disassembled form, in particular in the form of a kit.

[0024] Preferably, the frame—on at least one of the open surfaces or sides encompassed by it—is covered by a cover layer, in particular in the form of a film or plate, which is or can be attached to the frame and / or the connector elements of the support structure. In particular, the frame and the connector elements are designed and arranged such that they form a flat structure toward the plate.

[0025] The covering layer is preferably made of photovoltaics, solar modules, fire protection panels, insulation panels, layered elements such as foil, plasterboard or gypsum fiberboard, stone panels, wood panels, glass panels, plastic panels, cement fiberboard, roofing foils.

[0026] Preferably, the connecting elements or the sleeves or the frame are designed to create connections with metal elements, in particular with metal pipes, supports, screws, bolts, eyelets, with which, for example, the support structure can be connected to a metal structure. For example, with an anchor system or connection system in a floating photovoltaic system or with steel supports for a roof such as a carport or with a house wall such as a concrete or brick wall. Preferably, additional cross connections are present in the panel element and / or frame, which form cavities inside the panel element. These can be designed in particular for air circulation, for electrical or fluid lines, electronic components, installation of insulation material, windows, doors, brackets or anchors or metal supports.These are preferably mounted in the frame or on the connecting elements and are made of metal, plastic or wood, for example.

[0027] Preferably, the sleeves - for inserting the round rods - are laterally closed with a film or membrane which is pierced when the naturally grown round rods are inserted, in particular wherein this is designed and arranged to form a sealing effect against a lateral escape of the filling material between round rods and connecting elements.

[0028] The invention specifically relates not only to the support structure itself, but also to a structural element or building component, in particular in the form of a plate element. A plate or plate element can be understood here, for example, specifically as a three-dimensional component that has a thickness t and a flat, planar shape. The thickness t is small relative to the other dimensions of the component. In technical mechanics or construction engineering, a plate is a component that is spread out in a plane and consists of rigid material (flat surface structure). A surface component that is not flat but curved is often referred to in the literature as a shell - however, for the purposes of this invention, such a component is also included in the term plate element. This structural element is in a grain-positive construction orSandwich construction and has a support structure as described in this document, wherein the support structure is filled or filled, can be filled, or surrounded by a solid material. For example, with clay, Styrofoam, insulation (as with blown-in insulation), sand, etc.

[0029] The invention also relates to a method for producing a support structure from naturally grown round rods, in particular bamboo rods or wooden branches, specifically for construction elements, building elements, or panel elements as already mentioned above. The method involves providing connector elements, each forming at least one sleeve. Or, in embodiments, two or more than two sleeves - or two connectable / connected elements, each with a sleeve, which are arranged / aligned at an angle to the grid arrangement to one another - or two-part connector elements, each with a sleeve, which are rotatable relative to one another. A sleeve can be designed, in particular, as an opening, hole, bore, or cavity.

[0030] The process involves inserting the naturally grown round rods, particularly loosely, into the sleeves of the connector elements. This can be done in a grid-like or honeycomb-like arrangement, with the connector elements each being located at at least some or all of the nodes of the grid arrangement. This is followed by filling or filling any remaining space between the sleeve and the naturally grown round rod(s) enclosed by it with a fixing agent to secure the naturally grown round rod, particularly with adhesive, hot melt glue, silicone, resin, cement, or other fixing or filling agents mentioned here.

[0031] Preferably, the ends of the naturally grown round rods are inserted into sleeves formed or attached to at least one side wall (or preferably to a surrounding frame) of the support structure. These sleeves are also filled to secure the naturally grown round rod(s).

[0032] Preferably, the naturally grown round rods are flexible when inserted, for example by being still fresh / green or by being made flexible with moisture, heat and / or steam.

[0033] The invention also relates to a method for producing a support or support rod or support element from naturally grown round rods, in which method individual bamboo rods or bamboo tubes, or a bundle thereof, are inserted into a sleeve. The sleeve is preferably made of metal or plastic and can form a connecting element. During insertion, the sleeves or the connecting elements are inserted into a mounting bracket such that the sleeves or the connecting elements each lie on the same level, in particular while the bamboo rods are being passed through the sleeves, and preferably also while an adhesive, in particular made of epoxy resin or polymer concrete, is being filled into the sleeve and curing. In particular, this filling takes place before the bamboo is inserted or after the bamboo is inserted. The sleeves orConnector elements or their mounting surfaces in a defined geometric position, for example in a plane, in order to later mount a panel to them. In another embodiment according to the invention, it is not the sleeves or connector elements that are inserted into a mounting bracket, but the bamboo sticks - and then the sleeves or connector elements are aligned such that they are in a desired position, e.g. all in one plane. In particular, the sleeve can be sealed at open points during filling by an assembly device (plug, seal, air pressure) so that no adhesive can escape. Alternatively or additionally, there can be a collecting basin for the adhesive underneath the mounting bracket. In particular, supports consisting of round bamboo sticks of different thicknesses can be joined together in this way.This allows bamboo with large diameters to be inserted centrally in a bundle of bamboo to provide a load-bearing effect, whereas rods with smaller diameters can be used laterally.

[0034] The invention also relates to a method for producing a lattice arrangement from naturally grown round rods, in particular bamboo rods, with a provision of connector elements with at least two sleeves (or two connectable / connected elements, each with an opening / hole / bore / sleeves, which are arranged at an angle to the lattice arrangement to one another, or two-part connector elements, each with a hole which are rotatable / movable relative to one another). The naturally grown round rods are inserted into the openings of the connector elements in a lattice-like arrangement, wherein the connector elements each come to lie at at least some of the nodes of the lattice arrangement, and the remaining openings between the naturally grown round rods and the sleeves of the connector elements are filled / filled with an adhesive, in particular with epoxy resin, polymer concrete.

[0035] Preferably, the grid arrangement is enclosed or encompassed by at least one side wall or preferably a continuous frame, which also has (at least on one side) sleeves into which the naturally grown round bars are inserted and also inserted.

[0036] In other words, various embodiments of the invention can also include the following: A building element or panel element, particularly designed for constructing a roof element or wall element for a structure or building such as a garage, house, soundproof wall, bus stop, house roof / ceiling, flat roof, roofing, carport, particularly as a photovoltaic carport, as well as a support element for an open-space PV system or BI PV, as well as a floating photovoltaic module (FPV) or FPV system, which is designed in a composite or sandwich construction. This can be specially designed with a combination or partial combination of the features: a support structure made of bamboo or a renewable material made from bamboo DNA (hereinafter referred to as "bamboo") and therefore has similar properties to bamboo, which tends to form an irregular shape, e.g.by knots, as well as deviations in thickness / diameter or in straight growth; whereby the bamboo is preferably naturally grown; whereby connecting elements are attached to one or more bamboo sticks / bamboo tubes (of the support structure); whereby on the main beams of the support structure, at each end of the bamboo.

The sleeve is preferably made of plastic or metal. The sleeve completely encloses the bamboo and preferably the filling material also encloses the bamboo. The filling material is an adhesive,Epoxy resin, silicone, hot melt adhesive, or liquefied plastic, polymer concrete, cement, or resin, preferably in liquid form, is injected into the connecting element(s) and hardens there. This serves to enable a uniform transmission of force from the outside via the connecting element to the bamboo. Preferably, the connecting elements are designed with an injection channel for this purpose. The connecting element can comprise a single bamboo of the support structure or multiple bamboos of the support structure.Both side by side and / or one above the other (bamboo bundles) as well as intersecting bamboo (e.g., as a lattice) on multiple levels. Preferably, the bamboo extends through the sleeve, or the sleeve consists of several parts that are joined to the bamboo; at least one of the sleeves is a grid sleeve with a mounting plate (e.g., with pre-drilled holes) and / or a threaded sleeve with an internal or external thread. Preferably, such sleeves are located at each end of a bamboo main support; the support structure is formed on at least one side, preferably enclosing, with a frame, in particular with a frame with an L- or U-shaped cross-section. Preferably, assembled from L-profiles or U-profiles. The support structure preferably rests against the support surface at the angle or at the bend of the L-shape; the connecting element of the bamboo has a sleeve.which has direct contact or a connection with the profile, which is also formed with filled or fillable sleeves, into which the ends of the bamboo are inserted, so that a force transfer from the support surface of the profile to the structure is possible. The frame is preferably made of plastic such as acrylic glass, HDPE, WPG, BPC or metal (steel, aluminum); whereby the bamboo support structure forms a lattice or honeycomb arrangement and intersects at nodes, whereby at least a subset of these nodes forms a connection between the intersecting bamboo with one of the connecting elements; whereby the support structure can be arranged on one level, e.g. side by side as a lattice or honeycomb pattern, or can also consist of several layers or levels in which the bamboo sticks rest on one another; whereby additional cross connections or reinforcements in the frame, in particular made of metal,Plastic or wood, which form cavities inside the panel element, in particular for air circulation, installation of buoyancy aids, insulation material, windows, doors, brackets or anchors or metal supports that are attached in the frame or to the frame (sleeves), in particular for electrical cables and / or electronic components or pipelines; wherein the support structure is provided in disassembled form or in individual parts, in particular in the form of a kit; wherein the frame with the grid arrangement is at least partially, in particular completely, filled with a solid, in particular in the form of an insulation material, buoyancy aid or fire protection material.

[0039] In other words, according to the invention, a method for producing a support or support rod or support element from naturally grown round rods can also be carried out, in which individual bamboo rods or bamboo tubes are bundled together in a sleeve, preferably made of metal or plastic. In particular, with at least a subset of the following features: sleeves are inserted into a mounting bracket so that the sleeves each lie on the same plane.The bamboo or bundle of bamboo is guided through the sleeves; the sleeve is filled with an adhesive, preferably made of epoxy resin or polymer concrete, before or after the bamboo is inserted; the sleeve is sealed at the open points during filling using an assembly device (plug, seal, air pressure) so that no adhesive can escape and / or there is a collecting basin for the adhesive below the assembly bracket. In this way, supports can be joined together which consist of round bamboo rods of different thicknesses. For example, bamboo with a large diameter can be inserted centrally in the bundle of bamboo to provide a load-bearing effect, with rods with smaller diameters being inserted laterally.

[0040] Production of a lattice arrangement from naturally grown round rods (in particular bamboo rods), with the provision of connector elements with at least two sleeves or holes / openings (or two connectable / connected elements, each with a sleeve, which elements are optionally rotatable / movable against each other), which are arranged at an angle to the lattice arrangement to one another; inserting the naturally grown round rods into the openings of the connector elements in a lattice-like arrangement, wherein the connector elements each come to lie at the nodes of the lattice arrangement; filling / filling the remaining openings between the naturally grown round rods and the connector elements with an adhesive, in particular with epoxy resin, polymer concrete, optionally with biological or biodegenerative adhesive such as glue; wherein the lattice arrangement is connected by at least one side wall orpreferably enclosed in a continuous frame, which also has sleeves (at least on one side) into which the naturally grown round rods are inserted and also fixed or filled;.

[0041] A building element or panel element according to the invention consists, for example, of individual bamboo or bamboo-like plants based on the DNA of bamboo. These were preferably only pre-processed in such a way that they are as straight and durable as a rod or tube in their raw form, e.g. by drying and bending. As a natural product used directly, bamboo has curves and unevenness and is not perfectly straight along its length. This makes bamboo difficult to process for standardized products or in the industrial sector. Industrially, only its fibers are primarily processed, or in handicrafts, split bamboo is often further processed, which reduces the stability of the bamboo. Any drilling or sawing often weakens the naturally grown structure of the bamboo.

[0042] The element according to the invention forms a support structure with the bamboo. To connect the bamboo to other elements, the support structure or an individual bamboo of the support structure—hereinafter also referred to as the bamboo support or main bamboo support—has connecting elements, preferably sleeves, at the respective ends of the bamboo. The bamboo extends into or through the connecting element or its sleeve, or is preferably completely enclosed by the connecting element or sleeve along its cross-sectional circumference.

[0043] In addition to the connecting elements or sleeves at the ends of the bamboo, one or more additional sleeves are attached to the bamboo. The bamboo extends completely through these connecting elements or sleeves and is preferably completely enclosed by them.

[0044] These connecting elements, especially sleeves, perform several functions. One of these is their standardization as a construction element. Because bamboo is often uneven and not perfectly straight in length, its use as a construction element is often difficult due to the lack of standardization.

[0045] In one embodiment of a production process according to the invention, for example, the bamboo is fastened in a standardized holder, to which the connecting elements or sleeves are then attached to the bamboo stick. Optical inspection and / or sensors can ensure that the connecting elements are aligned and mounted in such a way that they have a uniform height and width along the outside length of the support, and that any bulges and bends in the bamboo are compensated for towards the outside. The bulges and bends in the bamboo cane can cause cavities to form inside the connecting element or sleeve facing the bamboo, which can make perfect force transmission from the outside to the bamboo more difficult. These cavities are bridged using a filler or fixing agent, in particular adhesives such as epoxy resin, PUR adhesive, polymer concrete, or other cement-containing fillers.The bamboo is therefore only loosely inserted into the sleeve, which has a larger inner diameter or inner surface than the outer diameter or cross-sectional area of ​​the bamboo. The resulting gap is filled with the fixing agent, preferably essentially all the way around.

[0046] A further functional effect of the connecting element or sleeve is the connection of the bamboo support or bamboo with other elements, as well as a direct transfer of force from or to these elements.

[0047] These additional elements can in particular be panel elements such as plastic panels, plastic films, drainage panels, wooden panels, metal panels, building material panels such as gypsum fiberboard, insulation panels such as mineral wool panels, cement fiberboard or photovoltaic modules. Here, a standardized external shape of the connecting element can serve as a standardized support surface for the panels distributed along the entire length of the bamboo. This enables direct force transfer from the panel to the bamboo underneath. So that forces acting on the panel element from below, e.g. due to wind or waves, can be cushioned via the bamboo structure, the connecting element preferably also forms bores and / or an assembly structure which enables the panels to be assembled using connection techniques such as screwing, riveting, welding, gluing or binding, in particular better and faster than with bamboo-only constructions.In particular, holes in the connector elements preferably provide such mounting structures. Alternatively, loops, binding, or clip systems for attaching the panels to the connector element of the bamboo support can be provided from or to the connector element. In particular, the connector elements or sleeves that are not located at the ends can have or form such mounting options for additional elements, such as panel elements.

[0048] The connector elements are preferably made of plastic and / or metal, but can also be made of wood. Particularly at the ends of the bamboo or bamboo supports, these connector elements or sleeves can be used to create connections with metal elements. In particular, metal tubes, supports, screws, bolts, and eyelets can be used, for example, to connect the bamboo support to a metal structure - for example, an anchor system or connection system for a floating photovoltaic system, steel supports for a roof such as a carport, or even to a house wall such as a concrete or brick wall.

[0049] Depending on the intended use, the sleeve can have special features for connection technology. For example, the sleeves at the respective ends of the bamboo can be designed as post sleeves or threaded sleeves. The post sleeves can, in particular, have mounting plates to which additional elements can be attached, e.g., by drilling, welding, or other known mounting methods. Such a threaded sleeve can have an internal and / or external thread, allowing extremely stable, permanent, or detachable metal connections to be created, preferably without the need for welding.

[0050] The connecting elements, particularly those sleeves that are not located on the outside of the bamboo support structure, can be used not only to connect them to other elements but also to connect the support structure itself to produce a panel element according to the invention. The support structure preferably consists of a lattice or honeycomb structure. The lattice can consist of a single level of bamboo supports or can be formed from multiple levels or layers of individual bamboo supports. Since it is a natural material, the stability and availability of corresponding thicknesses of the naturally grown round rods can vary. In order to nevertheless produce or ensure the necessary load-bearing capacity, in one embodiment several bamboos can be combined, e.g. as a bundle of bamboo sticks or bamboo tubes, and these can then be joined together as a complete, single element in the support structure.Such a bundle can also be enclosed by a single connector element or a single sleeve. In principle, not all lattice elements need to be directly connected to the frame; some or all of the naturally grown round bars can simply rest directly on the frame, so that external forces are transmitted to the frame and the support structure, even without a sleeve.

[0051] The connecting elements, especially their sleeves, can enclose the individual bamboo supports and be connected to form a support structure using additional joining techniques such as ties, loops, screws, and clamps. The connecting element or sleeve can also completely enclose the respective bamboo supports at the connection points, even with multiple levels or layers. This makes it easier and more configurable to transfer forces via these connecting elements to the entire support structure.

[0052] To ensure the support structure can be easily used, especially as a panel element or construction element according to the invention, and / or to protect the bamboo from environmental influences such as moisture, sunlight, or insects, a finished panel element preferably has a frame that completely encloses the side edges of the panel element and its support structure. This frame is made, for example, of plastic such as PE, HDPE, acrylic glass, PVC, wooden plastic composite (WPG), bamboo plastic composite (BPC), PC, or PP, or of wood, or of metal such as steel or aluminum.

[0053] The frame preferably has an L-shape or U-shape so that the bamboo or the bamboo supports with the outer connecting elements, in particular the sleeves, lie directly against the angle of the L-profile or U-profile of the frame, thus ensuring direct force transmission here too. In addition, the frame can form further reinforcing structures, such as metal plates or metal supports. Such a reinforcing structure can serve, for example, to connect the roof of a carport to another panel element according to the invention or to a metal support which is designed to hold the panel element according to the invention as a roof element. Such a reinforcing structure can also be formed between an angle of the frame and the bamboo support so that the force is transmitted via the frame and its reinforcing structure to the bamboo support via its connecting element or its sleeves.A design with a U-shape or L-shape of the frame offers the most stable but at the same time cost-optimized form for attaching photovoltaic modules or other smaller plate elements such as insulation panels, drainage panels, gypsum fiber panels, foil, etc. to the building element or plate element according to the invention.

[0054] Such a frame can also be created by an enclosing wall structure made of common wall materials such as concrete or brick. Connecting elements or sleeves can then be attached to these, into which the naturally grown round bars are then inserted according to the invention, thus creating, for example, a combination or a static connection between classic solid construction and the inventive support structures or panel elements.

[0055] Via the frame with the support structure, the inventive component can be connected to other inventive components or panel elements, as well as to other structural elements of a product. Thus, force can be transmitted outward via the frame and the grid structure, allowing several floating photovoltaic modules or components to be combined to form a closed and connected system, or a building to be constructed in which the forces can act across the entire structure of the system or building.

[0056] The frame can serve as a further standardization of the support structure, which provides additional connecting elements and assembly structures, such as indentations, sleeves, snap-in devices and indentations in which elements from the support structure such as a bamboo stick or a bamboo bundle can be inserted and thus can be directly connected to the frame.

[0057] To enable the building elements to be connected to other house walls or floating photovoltaic modules, e.g., as a house wall or as a floating photovoltaic module, one embodiment of a building element according to the invention can have openings to the outside. This is preferably achieved via an additional connecting element, such as a sleeve (T-beam sleeve, threaded sleeve, post sleeve, or similar). Threaded rods, metal rods, or other rods can thus be inserted into the sleeve from the outside via this sleeve. The sleeve is preferably directly connected from the interior of the frame to the internal support structure.

[0058] As a result, the structural element according to the invention can be firmly connected to another structural element according to the invention or to other conventional structural elements such as a basement ceiling or floor base plate, etc., for example by means of joining techniques such as welding, gluing, plugging, wedging, riveting, or screwing. To provide additional stability to the internal support structure, additional reinforcements or rods made of metal or plastic can be inserted - in addition to the support structure according to the invention with naturally grown round rods - particularly in places with high or special load requirements or in safety-critical areas.

[0059] Bamboo, in particular, as a naturally grown round rod, has more buoyancy thanks to its air inclusions and its internal chamber system, as well as better insulating properties than a normal, solid wooden trunk or a solid wooden slat.

[0060] Because these natural round bars are always slightly misshapen and uneven, some applications require an additional layer to give the building element, such as a house wall, a smooth appearance and feel on the outside - even across the entire surface and not just in the area of ​​the support structure frame. Suitable materials for this include free-flowing materials or solids such as fire protection mats, insulation materials such as rock wool impact sound insulation boards, or buoyancy materials such as Styrofoam balls / EPS. Materials such as clay, plaster, cement, seaweed, bagasse, hemp, lime, mineral wool flakes or stuffing materials (e.g. rock wool flakes, glass wool, glass wool flakes), or sand. This allows a smooth surface to be created on the outside despite a very natural and not perfectly straight or flat internal support structure.The support structure is preferably completely enclosed by a frame, which frame is preferably made of a bio-composite or natural fiber-reinforced plastic such as wooden-plastic composite (WPC) or bamboo plastic composite (BCP), PE (polyethylene), HDPE, polycarbonate, acrylic, PET (polyethylene terephthalate), PP (polypropylene) or another plastic material, such as a bio-plastic such as PLA (polylactide).

[0061] These frames are preferably manufactured from large-format compression molding (thermoforming, deep drawing, pressing) or from a profile using a continuous extrusion process, and are then cut to size, bent, and / or joined using joining techniques such as welding or gluing. Flat profiles, but also L-profiles in particular, are suitable for this purpose, as they offer increased stability and additional mounting surface. However, other profile types such as U-profiles, T-profiles, or other profiles can also form the frame. Alternatively, the frame can also be assembled from individual panels using sawing, bending, and / or joining techniques such as welding. These panels can also be manufactured using an extrusion process. Alternatively, other thermoforming processes or other plastic molding methods can be used to produce the required elements, such as compression molding, deep drawing, etc.

[0062] The frame can also have openings, preferably created by drilling or punching, and / or form connecting elements such as recesses, which can serve to secure the internal support structure. These openings or recesses can also be used to secure connecting elements such as nuts, threads, and sleeves (screw-on sleeves, threaded sleeves), or to provide support, and optionally also to make the internal support structure itself accessible or visible from the outside.

[0063] Additional cross members and reinforcements made of the same material as the frame can be attached to the frame itself, preferably plastic and / or other materials such as wood and / or metal. Such cross members can provide additional stabilization of the frame. Furthermore, they can also be designed and arranged to provide support and structure for other elements, for example door frames, window frames, sockets, solar modules, photovoltaic modules, solar thermal modules, power lines, insulation materials such as rock wool panels, mounting plates / insulation panels made of wood or metal (e.g. for wall cabinet installation), electronic components (such as sensors, lighting devices or inverters), pipelines, pipe couplings, drain pipes, ventilation pipes and / or empty conduits, etc.

[0064] In designs for a house, openings can also be provided in the frame which serve to fill a liquid or free-flowing filler during final assembly, for example clay, polystyrene balls, mineral wool flakes such as rock wool flakes and glass wool flakes, seaweed, hemp, cement or sand, etc. These fillers can be specially selected depending on the application in order to provide weighting, fire protection, thermal insulation and / or soundproofing, etc. Cross beams or cross connectors can also be used for this purpose.

[0065] These openings in the frame can also be used to connect the inner or internal support structure of the building element to other building elements, particularly for load-bearing connections. These can be detachable or permanent connections.

[0066] In the case of a floating photovoltaic module, for example, a sleeve (e.g. a threaded sleeve), preferably made of metal or plastic, can be inserted into the frame. Elements of the inner support structure are inserted directly into the sleeve. In particular, since the naturally grown round rods are natural materials whose shape is not standardized, they do not completely fill the sleeve, but rather a gap remains which is different for each pairing of its shape and size. The round rod is fixed in the sleeve using a fixing agent or additional material or filler. The fixing agent for attaching the naturally grown round rod, preferably bamboo, can in one embodiment be a tightenable screw or bolt, with which the round rod is fixed in the sleeve. In another embodiment, this fixing agent is a hardening orAdhesive filler material, which is preferably introduced in liquid or plastic form and hardens into a solid or elastic material after introduction. The fixing agent can alternatively be a wedge or stuffing material such as stuffing wool, mineral wool flakes, rock wool flakes, Styrofoam particles, foams such as PUR foam, or adhesives or resins (e.g. epoxy resin), or clay, polymer concrete, adhesive, glue, cement, or cement-based material. In addition to the additional material, a rivet, bolt, screw or nail can also be inserted to fix the sleeve or thread to the internal support structure. To prevent these round rods from slipping, the internal support structure is connected to itself via additional connecting elements.

[0067] Using one or more metal rods or special threaded rods, individual structural elements can be connected via their frames and / or crossbeams using their sleeves or threaded sleeves. This allows for force transmission between the internal support structures of the connected structural elements. Additionally, reinforcements or additional such rods can be added to further strengthen the connection, and additional reinforcement plates or reinforcements (e.g., beams) made of metal, plastic, or wood can be added to the frame and / or frame structure (crossbeam) to reinforce this point.

[0068] Pipe connections and / or electrical cables of the individual components can also be connected to one another via openings in the frame or on the frame cross members or frame structures. The frames can have corresponding openings, connections or contacts for this purpose. In this way, for example, various components according to the invention, such as the walls of a house or floating photovoltaic modules, can be combined to form an integrated overall system in which a system of electrical and / or flow connections adapted to the intended use is produced or provided. When connecting the modules or components according to the invention, additional sealant can optionally be added to close any gaps between the components and also between the individual openings or connecting elements such as the threaded rods. This prevents water or other environmental influences from affecting the respective connection.Depending on the application, different sealants can be used, such as silicone, glass, plaster, cement, resins, foams such as PUR foams, adhesives or other sealants.

[0069] In the case of floating photovoltaic modules, additional anchor systems or brackets can be attached to the frame, to which an anchor rope or anchor chain (mooring line) can be attached, at the end of which an anchor, preferably made of concrete and / or a sea anchor, can be attached. The sea anchors serve to keep the system in the water, even in strong waves. The electrical contacts or cables can also be provided or run over the frame, so that the individual modules can be connected to one another or the power lines can be bundled to form a main connection on the system. This main connection can then be connected to the power grid on land using a submarine cable, power line, or cable bundle. Such a main connection can optionally have a predetermined breaking point orIntended decoupling should the forces (waves) on the system become too great in order to limit any damage and enable faster reconnection.

[0070] In the case of floating solar modules or such an entire system (the connected floating modules), the outer floating modules of the system can also be equipped without commercially available photovoltaic modules in order to save costs and to provide these as a kind of buffer against wave action. This can also prevent or reduce algae growth on the actual photovoltaic modules. A special covering layer can be applied to the modules for this purpose, which prevents algae growth. Furthermore, the additional space created can also be used to park autonomous cleaning robots, which can be automatically charged on the floating modules via a plug and play system or via wireless power transmission. In addition, an object or bird protection orWaterfowl protection can be installed to prevent birds from landing on the system, such as cannons (e.g. deterrent screens) or simply protruding barbed wire, nails or nail boards. To enable easy installation of the system or the individual modules on the water, as well as to provide expandability, the inner modules can be connected using detachable and / or permanent plug-in connections (e.g. threads or bolts). The outer modules of the system serve to fix the modules of the overall system and are firmly connected to one another, forming a type of frame around the entire system, which is secured and connected using bolts, screws, nuts or other connecting elements, so that the inner plug-in connections of the inner modules cannot come loose.For example, this can be achieved using appropriate metal connections made of metal supports or even cables (wire). Standard module openings, plug-in connections, or metal plates can serve as supports for these external connecting elements. Alternatively, the individual modules can be firmly connected to one another, e.g., via threaded rods or by welding or by applying heat / cold (expansion) to metal connecting elements.

[0071] In all applications, the frame can also be used to assemble and connect the internal support structure. Through its standardized openings, the frame provides fixed specifications for the natural and non-uniform internal structure made of virtually randomly shaped, naturally grown round rods, which are compensated for by the support structure's connector elements according to the invention. Especially with small diameters, a low degree of drying, or special pretreatment such as soaking, the naturally grown round rods can be at least partially bent during the manufacture of the inventive support structure or a building element, which can facilitate the insertion or manufacture of the support structure.

[0072] Overall, in one embodiment the frame - optionally with a further frame structure such as the cross members and an outer shell - forms a type of tank which completely surrounds the component and preferably hermetically seals it off from the outside. At best, such a tank can only be accessible through provided openings or through an openable part of the tank or frame structure, so that insulating materials, fillers, fire protection agents, soundproofing agents, electronics, pipes or the like can be filled into or installed in the tank or the frame of the tank or corresponding support structures of the tank or frame. In this case, the frame in the aforementioned embodiment can also form its own internal structure which serves to better fasten the outer shell or to make internal components, e.g. electronic cables or electronic assemblies, accessible from the outside and / or to better store these in the tank or frame.Frames can be attached. For example, in the case of photovoltaic systems or components, the frame can contain plug-in contacts and fastening elements for easy connection and mounting of photovoltaic modules, allowing them to be installed virtually as a plug-and-play solution, with standardized power transmission within the module. This also allows for the connection of the individual components, roofing, or floating photovoltaic modules, so that they can form a functioning system that produces electricity and in which the electricity is transported via an internally designed or arranged main cable.

[0073] The openable part of such a tank can, for example, be an entire house wall, so that, for example, clay can be introduced here and then sealed or closed with the tank shell or outer shell, e.g., as a film. The outer shell can also preferably have openings facing inwards (inside the house) – in addition to, for example, electrical outlets – so that, for example, the clay introduced can positively influence the room ventilation by regulating humidity. For this purpose, additional ventilation shafts can be integrated into the frame, forming the frame structure.

[0074] The tank's outer shell or covering layers, which can be attached to the frame or a frame structure, serve to prevent or significantly mitigate external influences such as sunlight, insects, mold spores, moisture, and air from affecting the internal support structure. Depending on the intended use, different shells and materials are required.

[0075] Floating photovoltaic modules, which can also be used in seawater, require a particularly hermetic seal. This can be achieved using LDPE film, metal, or other plastic materials, for example. This is preferably done on both or all sides of the module, so that the interior is truly hermetically sealed and accessible only through designated openings and / or contacts. The commercially available and standardized photovoltaic modules can then be attached to the frame or frame structure such as crossbeams, L-profiles, U-profiles, or other profile shapes and can optionally be additionally secured with sealant and clamps. Glass-glass photovoltaic modules are preferably suitable for seawater, but thin-film modules or even normal glass-film modules are also suitable.

[0076] In all embodiments, the sleeves can preferably be made of metal or plastic and preferably have a thread or a mounting plate. Bamboo (bamboo stick, bamboo tube, bamboo bundle) is added to the interior of the frame or between the sleeves of the frame, and the bamboo is fixed in the sleeve, for example by stuffing or gluing. On the other side of the sleeve opening - i.e. outside the frame - a threaded rod or bar can then be inserted, which can serve to connect components or modules according to the invention to one another. The bamboo preferably forms a lattice structure inside, although not every individual bamboo needs to be in a sleeve. Additional bamboo can also lie loosely in the frame and be firmly connected to the lattice bamboo structure with connecting elements such as loops, wire, ropes, clamps, or sleeves.Such loose bamboo without pods preferably abuts directly against the frame so that it can support the frame structure.

[0077] In particular, designs of floating photovoltaic modules or building elements for carport roofs or roofing in general have an L-profile frame or a frame in the shape of a half-shell. Preferably, the L is upside down, meaning the bend of the L is at the top, not the bottom - an essentially horizontally aligned leg of the L is therefore at the top. Sleeves are inserted into the frame directly within the L-shape - i.e. below the bend or angle, so that they support the L-shape or the surface of the bend or angle. The standardized sleeves thus form the main supports for the frame, as they connect the irregular bamboo structure within the frame, so that the entire force acting on the frame is transmitted via the sleeves to the bamboo structure. The bamboo structure should not be higher at the top than the L-profile itself, so that corresponding crossbeams or standardized photovoltaic modules can be mounted flush here.However, the bamboo may protrude slightly downwards or to the sides.

[0078] In order to enable smaller standard photovoltaic modules, films or sheet materials to be installed as the cover surface of a panel element or component according to the invention, the fastening surfaces of an L-profile of a frame may not be sufficient. Here, the connecting elements - in particular their sleeves - can be used to provide additional support for the cover surface and to transfer the forces cleanly to the support structure. Additional cross members or structures can also be used - preferably made of the same material as the frame and in particular mounted on the frame or integrated into it so that they are flush with the cover surface formed by the L-profile, resulting in a flat overall surface for mounting the standard photovoltaic modules or for attaching the film or sheets. For example, buoyancy aids such as Styrofoam panels can be attached to make the photovoltaic modules float.

[0079] Additionally or alternatively, structures in the form of hollow spaces can be created to contain buoyancy aids, such as polystyrene balls. Such cross members or additional structures of the frame itself can also be thinner, just as thick as the frame profile, or even thicker. It should ideally be ensured that such a cross member or additional structure can transfer force to the inner support structure (e.g. the bamboo). For this purpose, there can be some additional supports from the cross member to the underlying inner support structure made of bamboo, or its connecting elements. These can be made of the same material as the frame (e.g. plastic or metal). For example, in the form of a very large sleeve which is connected to the cross member orthe additional structure of the frame and the sleeve through which the bamboo is inserted, which is preferably secured in this sleeve with additional stuffing material, wedges, adhesive, or filling material (such as rock wool flakes, PUR rigid foam, resin, or similar). If additional plastic supports are provided, these can be sawn or milled to fit the shape of the bamboo so that they rest perfectly on the bamboo.

[0080] As an alternative to standard photovoltaic modules or the photovoltaic modules available on the market, a floating photovoltaic module, BI PV or PV roofing for e.g. a carport can also be manufactured based on a component according to the invention, also based on individual solar cells or photovoltaic cells (instead of modules with multiple cells). For this purpose, an additional damping layer is preferably introduced between the internal, inventive support structure (e.g. made of bamboo) and the cells. This damping layer is preferably made of EVA or another plastic material and preferably covers the entire support structure. The solar cells or photovoltaic cells can be manufactured from conventional wafers or sprayed or attached directly onto a plastic film, e.g. made of PET, acrylic glass, FER or PTFE, for example using known aSi solar cell processes or Perwoskit.

[0081] As an alternative to photovoltaics, solar thermal energy can also be provided with a support structure according to the invention. For this purpose, pipes are inserted into the interior of the frame structure, and a heat-conducting or heating plastic or glass outer shell is attached to the frame structure, allowing the liquid contained in the pipes to be heated by solar radiation.

[0082] In another embodiment of the invention, house walls can be provided with clay as a component with which the support structure is filled, which provides a certain degree of breathability and allows for better regulation of the room air. PET fleece or other breathable plastic materials are particularly suitable for this, in particular glass fiber, such as glass fiber mats or glass fiber wallpaper. Different materials can also be combined to form the outer shell. For example, a layer of plastic film or PET fleece as the first layer of the outer shell of a house wall can ensure that the insulation mats, fire protection boards or insulation boards inserted into the frame, which rest on the internal support structure and are held in place by the frame, are also fixed to the surface. With such an outer shell, the filling cannot fall out, even during transport.A layer of fiberglass applied to this layer, such as fiberglass wallpaper, provides a surface for the room and can add additional rigidity, which subsequently allows plaster or paint to be applied directly to the wall element.

[0083] For regions with low rainfall, clay alone can be applied directly to the internal support structure as an outer shell. To provide a degree of protection against insects and / or moisture, gypsum or tapioca starch can then be additionally applied to this outer shell. Particularly for building walls such as houses, the frames can be formed from a U-profile, L-profile, or a half-shell, with sleeves inserted at the bends (angles) of the profile. These sleeves form a standardized connection to the internal support structure, e.g., made of bamboo. This ensures that forces are transferred via the frame and sleeves to the entire support structure.

[0084] For building walls, plastic sleeves are preferably used, into which a cement-based or polymer concrete filler material is poured to secure the internal natural round bars within the sleeves. Alternatively, metal sleeves and / or lighter filler or fixing materials can be used.

[0085] Additional cross members or additional structures can be incorporated into the outer surfaces of the U-profiles. These can be used to form window or door frames, integrate electrical wiring, and / or create recesses for fire protection panels or insulation panels such as rock wool, particularly pressure-resistant insulation panels. If the frame or tank is made from a single half-shell, this can already incorporate such additional structures.

[0086] The frame structure or half-shell itself can have openings for filling the grid or honeycomb structure of the supporting structure with a filler, such as clay or insulation. These openings are usually only temporary for filling the clay, which preferably takes place directly on site, and are then closed again. In addition to permanently installed insulation panels, wooden or metal plates can also be temporarily attached or installed on site, allowing the clay to be injected under very high pressure without deforming the wall.

[0087] For efficient assembly of a house based on building elements according to the invention, these can be manufactured with a frame or a half-shell, preferably from plastic which is produced by extrusion, thermoforming and / or compression molding, welding and / or bending. Connecting elements, preferably sleeves such as threaded sleeves or post sleeves, are preferably already embedded in this frame. These connecting elements can be assembled manually or using robotic systems. The internal support structure made of naturally grown round rods, preferably bamboo in a lattice or honeycomb pattern, is then integrated over the connecting elements. To integrate power lines, pipes (empty conduits), windows, doors or to provide recesses for insulation materials, additional cross beams, brackets or general additional structures can be attached to the frame.These are preferably made of the same material as the frame and connected by welding, or a half-shell with openings forms the openings directly. The corresponding brackets, crossbeams, and even frames can be additionally reinforced with metal or wooden plates where necessary, e.g., to provide sufficient support for a door frame, to later provide sufficient support for wall cabinets in a kitchen, or to mount a support for a carport.

[0088] The support structure itself (e.g., the individual bamboo canes) is also connected to each other using connector elements, preferably forming a lattice or honeycomb structure. The connection can also be done manually or using robotic systems. Electrical cables and / or pipes such as conduits can then be installed, preferably manually. Insulation materials, window and door frames, and exterior shells can also be installed.

[0089] Assembly preferably takes place in a factory, after which the support structure or building element can be transported to a construction site. At the construction site, the support structure or building element can then be inserted as a house wall or ceiling element. For this purpose, metal rods, for example, are inserted from the outside into the frame of the building element, with which it can be firmly connected, for example, to a floor slab or basement slab or to other building elements according to the invention. This can be done using conventional joining techniques such as welding or screwing (threaded nuts or threaded sleeves). Subsequently, a filler, preferably a free-flowing solid such as clay, cement-based material, seaweed, rock wool flakes, or glass wool flakes, can be poured into the frame or structure, preferably on the construction site. This can be done manually or using an appropriate filling, blowing, or injection-molded system.To create a flat wall surface and prevent the corresponding filler from leaking out, an outer shell can be attached. This can be temporary or permanently attached to the building element. Finally, or before the outer shell is attached, an insulation layer, preferably made of mineral wool panels, can be applied to the designated recesses. This can ideally be done in the factory.

[0090] When assembling a roof element, a carport, or a floating photovoltaic module, a frame or half-shell with openings is preferably manufactured, preferably from plastic, e.g. by extrusion or thermoforming and / or compression molding, welding, and / or bending. The frame or half-shell can also be provided as a kit in several individual parts, which are put together during assembly. Connecting elements, preferably sleeves such as threaded sleeves or grate sleeves, are embedded in this frame or half-shell. These connecting elements can be installed manually or using robotic systems. The internal support structure, preferably made of bamboo and in the form of a grid or honeycomb pattern, is then integrated over the connecting elements.To integrate power lines, standard / commercially available photovoltaic modules and / or piping (empty conduits, drain pipes, ventilation pipes), additional crossbeams or brackets (generally additional structures) can be attached to the frame, preferably made of the same material as the frame and connected using welding. Such brackets, crossbeams and even frames can be additionally reinforced with metal or wooden plates where required, for example, to provide greater stability for an anchor system or roof rack. An outer shell can then be attached for sealing and / or the corresponding photovoltaic modules can be mounted and connected. When designed, for example, as a carport roof element or other building element, or as a roof covering or roof for a house, the outer shell can be constructed similarly to that of a floating photovoltaic module, provided that photovoltaic modules are to be integrated.If not, decorative foil, bitumen foil, shingles, plastic panels with and without a lacquer layer, glass, wood, MDF, plastic laminates (DKS, HPL, CPL, etc.), marble veneer (thin slate), glass fibre wallpaper, glass fibre mats, metal such as stainless steel or aluminium sheets can also serve as the outer shell.

[0091] Particularly for a carport, the panel element or roof element can be connected to the bamboo lattice using metal posts or supports, with bamboo tubes from the lattice being inserted into an opening in the support. The opening in the support can be filled with a filler or fixing agent, and / or a bamboo tube with a sleeve at the end is pushed into an opening in the support and secured in the support with a connecting device, such as a screw, bolt, or thread.

[0092] In particular, the bamboo sticks or bamboo tubes can each have sleeves at their ends to enable standardization. The bamboo is clamped in a holder, and the sleeve is then attached and filled with a filling or fixing material, particularly an adhesive or glue such as epoxy resin. This can be done manually or fully automatically using a camera or sensor and a robotic system.

[0093] As a flat roof for a garage, house, carport, parking lot roof or other roofing, the panel element or building element according to the invention can in particular also form a green or planted roof, wherein a corresponding protective film, drainage plate, root protection films, felt materials are attached to the frame and / or the connecting elements.

[0094] Particularly for general roofing or carports, frame reinforcements can also be designed as metal supports, which additionally support and stiffen the panel element or structural element according to the invention and can be attached, for example, to the roof support, which can also be made of metal. Thus, a kit can be provided in which the roof support, for example, is made of metal, can be inserted into the ground, e.g., stabilized with cement, and a horizontal metal support is mounted on each of the supports, to which the frame of a panel element according to the invention is attached.

[0110] Fig. 1 shows the frame (50, 51 a) of the building element (60) according to the invention with an internal support structure made of bamboo (56b), which is designed as a grid and is fixed by means of connector elements or connecting elements (55).

[0111] In the frame itself, the connecting elements to the bamboo lattice consist of sleeves (72, 66), the individual bamboo itself is also fixed to each other by means of connecting elements, so that they form a lattice (51 c).

[0112] Fig. 2, like Fig. 1, shows the frame (50, 51a) of the building element (60) according to the invention with an internal support structure made of bamboo (56b), which is designed as a lattice and is fixed by means of connecting elements (55). In addition, the frame or the half-shell forms an internal support structure made of cross members or additional structure (51). They can serve as an additional fastening surface for other components of the building element, as well as additionally stabilize the frame of the building element. Fig. 3 shows two building elements (60) according to the invention, in the form shown in Fig. 2, each with the frame (50, 51a) with an internal support structure made of bamboo (56b), which is designed as a lattice and is fixed by means of connecting elements (55). In addition, the frames form an internal support structure made of cross members (51). These serve here as a fixing option for an electrical line, pipe or empty pipe (54).Form corresponding recesses for the electrical wires. The two components are connected to each other by means of connecting elements (55) via the inner connecting elements, preferably sleeves (72). Metal supports / metal rods / threaded rods are preferably used as connecting elements between the components.

[0113] Fig. 4, like Fig. 2, shows the frame (50, 51a) of the inventive building element (60) with an internal support structure made of bamboo (56b), which is designed as a lattice and fixed by means of connecting elements (55). In addition, the frame forms an internal support structure made of crossbeams (51). These crossbeams additionally form recesses for fastening or stuffing insulation panels (56d). Additionally, reinforcements (76) are incorporated in the frame, forming an opening for the attachment of a door frame and window frame.

[0114] Fig. 5 shows the roof element of a carport (60) with a support from a bird's eye view (top view). The roof element forms a frame (50), which is preferably made from L-profiles (51b) or a half-shell with openings, so that the frame structure acts as a cross member or fastening surface (51a) for the fastening of commercially available and standard photovoltaic or solar thermal modules (71). In the middle, the frame additionally forms a cross member or structure (51a), preferably as a U-profile, so that large-area carports or roofs can also be made, and much smaller photovoltaic modules can also be securely fastened. These cross members, which are connected to the frame and are preferably made from the same material as the frame, also serve to absorb the effects of forces, such as, for example,to transfer snow load from the photovoltaic modules to the internal support structure; for this purpose, these cross beams form supports (51 a) and / or the internal support structure is directly connected to these cross beams by means of connecting elements such as sleeves.

[0115] In addition, an electrical cable is integrated into this cross member, which enables easy connection (plug and play) via this structure.

[0116] The frame also provides a mounting option for pipes (54b) which are used to drain (54c) rainwater.

[0117] The support (75) of the carport is preferably made of metal, preferably a sturdy metal rod made of aluminum or steel, and this support is directly connected to the internal support structures of the roof element via a particularly sturdy and large sleeve. Fig. 6 shows the connection of two structural elements according to the invention, more precisely in the form of a ceiling or ceiling wall, with a house wall in cross-section. The connection is established via sleeves (72) in each structural element and a metal support or metal bolt / metal rod or metal threaded rod (75).In addition, reinforcements (76) are incorporated into the frame of the ceiling component to stabilize the connection and provide additional connecting elements with support and fastening options. The internal support structure (56, 56b) of the component, preferably made of bamboo or wood (tree trunks), shown in the figure as a bundle of bamboo (56b), ensures that the components are connected in this way that forces are transferred from the ceiling structure to the structure of the house wall. In addition, filling materials have been added to the components. In the ceiling, preferably a light material with good insulating properties such as glass wool, rock wool, Styrofoam / EPS, hemp, seaweed, as well as materials similar to those used in house walls, or heavier, free-flowing materials such as clay, sand, or cement-based building materials.

[0118] Fig. 7 shows the connections between two house walls and ceiling construction elements, whereby the connection is made via metal bolts / metal rods or metal threaded rods (75) and additionally pipe couplings or openings and connection connections for power lines (54a), empty pipes or pipelines, which are located inside the house walls, are connected via the frame.

[0119] Fig. 8 shows two components according to the invention embodied as floating photovoltaic modules, which contain electrical lines (54) and / or pipes (54b) for draining rainwater or water from wave action. Rainwater can be directed to the drainage pipes via a structure embedded in the frame or structure.

[0120] Additionally, these pipes can be used to aerate the water below, directing air from the surface of the floating photovoltaic module into the water via funnels or electrical components or other elements.

[0121] Similar to Fig. 5, commercially available and standard photovoltaic or solar thermal modules (71) are mounted on the surface of the component. These are attached via an additional structure of the frame, preferably using L-profiles or a half-shell.

[0122] The component forms connecting elements (55) such as sleeves (72), preferably made of metal, with corresponding openings across the frame, through which metal rods (threaded rods) or metal bolts (75, 75a) can then be inserted. These connections can be either non-detachable or detachable.

[0123] Fig. 9 shows the component according to the invention in the form of floating photovoltaic modules (60) and its connection to an anchor system (77) and a submarine cable or land line. The anchor system preferably consists of a reinforcement (76) embedded in the component according to the invention in the frame (50), into which a connecting element, preferably a sleeve, is mounted, which connects the internal support structure to the frame. A connecting element (55), such as a screw, is inserted into this sleeve (72) via openings in the frame. B. a metal bolt or metal rod (threaded rod (75, 75a) is introduced, which preferably forms an eyelet or other connecting element at the end (77, 77c) so that a rope or chain or mooring line can be attached to it (77, 77b). At the point where corresponding mooring lines or anchor ropes are attached, the connecting element is particularly strongly connected to the internal support structure, preferably made of bamboo.This can be achieved by means of reinforcements in the frame as well as additional reinforcements which enable force transmission to several support elements of the internal support structure (preferably made of bamboo) rather than sufficient to a single connection of the internal support structure.

[0124] This can be directly attached to an anchor (77, 77d) and / or a buoy (77, 77a), with the buoy itself being attached to an anchor (77, 77a). A firm anchoring can then be ensured via the buoy. In addition to a firm anchoring, a sea anchor or floating anchor can also be attached via this connecting element (77, 77c) of the inventive component.

[0125] In order to enable any number of floating photovoltaic modules to be connected together to form a platform, these form corresponding connections via connecting elements (55) or sleeves (72) and metal rods (75) as well as electrical lines (54, 54a) embedded or mounted in the frame in order to connect further modules and also to connect a submarine cable or land lines to the platform.

[0126] To prevent damage to either element in the event of strong wave action and the resulting tension on the connection between the module and the submarine cable, this connection features a predetermined breaking point (78a) or a detachable power line (78) that releases the connection if excessive force is applied. This allows for repair without major effort or minimal damage.

[0127] Fig. 10 shows the component according to the invention as a carport (60, 60a) in a side view with electrical components (53) such as lighting elements (53a) and proximity sensor or IR sensor, distance sensor (53b), as well as an optional e-charging station and / or battery (53c).

[0128] Fig. 1 1 shows the building element according to the invention in the form of a house wall (60b), which has been prepared and pre-assembled accordingly for transport to the construction site. Accordingly, the frame itself forms sleeves (72) or indentations, which can also be assembled (e.g. metal sleeves), with which the frame is connected to the internal support structure. The internal support structure preferably consists of a lattice made of bamboo (56b) or wood (tree trunks). The support structure is connected to one another by means of connecting elements (55). The frame (50) additionally forms cross members (51a), these cross members form corresponding openings for filling the interior of the building element with filler (58d) or for connecting electrical devices such as a socket (53e). Corresponding electrical cables or pipe couplings / pipelines and / or empty pipes (54) integrated in the building element are led through openings orConnections accessible from the outside. Additional recesses or other structural features are provided on the crossbeams (51) to accommodate the installation of insulation material or reinforcements. Preferably, insulation panels such as mineral wool panels, rock wool panels, wood panels, plastic panels, and / or steel panels.

[0129] Fig. 12, like Fig. 11, shows the inventive building element in the form of a house wall (60b), wherein the house wall has arrived at the construction site and has been connected to a base plate (79) via the integrated sleeve or connecting elements (72, 55) in the frame and a metal rod / bolt (75). Additionally, a filler (56), preferably clay, was introduced via the filling openings (58d).

[0130] Fig. 13 shows the components according to the invention embodied as floating photovoltaic modules (60), which are interconnected and additionally comprised of an outer frame made of floating modules without photovoltaic modules (81). These serve, among other things, to deter birds, reduce wave impact (81) on the photovoltaic modules, protect their technology, and prevent the growth of algae on the photovoltaic modules. In addition, they offer cleaning robots (80) the possibility of charging themselves, as well as being able to charge themselves (82) and house themselves stably and safely during storms and high waves.

[0131] Fig. 14 shows the crossbeams or frame structure (50) of the inventive construction element, preferably as a carport or floating photovoltaic module, in which the load of the photovoltaic modules is transferred by means of the frame structure to the internal support structure made of bamboo (56b) by means of supports from the frame structure and alternatively via a connecting element (55), here a sleeve (72). The sleeve is connected to the frame structure, and the internal support structure, here the bamboo, passes through the sleeve and is secured in the sleeve by means of additional fixing elements or filling elements.

[0132] Fig. 15 shows a house wall in which a two-layer bamboo lattice is used as a supporting structure. It consists of vertically bundled bamboo supports of various diameters, as well as simple, unbundled bamboo horizontally.

[0133] In the figure, the vertically bundled bamboo supports consist of bamboo with a diameter of 14 cm, as well as thinner bamboo with a diameter of 5 cm attached to the sides. The thicker bamboo stick has the task of bearing the load, while the bamboo sticks attached to the sides stabilize the load-bearing bamboo. Because they are bundled, the load-bearing bamboo cannot bend arbitrarily. For this purpose, the laterally attached bamboo sticks are not the same length as the load-bearing bamboo, so that the corresponding load does not rest on them. Fig. 16 shows a floor with three-layer bamboo lattices, where the sticks are bundled side by side in each layer. This means that the lattice is flat overall in height, but the load-bearing capacity is still relatively high.

[0134] Fig. 17 shows a wall element with a two-layer grid with sleeves on each of the round bars, so that a flat support surface or mounting surface is created for the frame, which forms a holder for fire protection or insulation panels.

[0135] Fig. 18 shows a cross-section of the frame profile (L-profile) and one of the bamboo supports (individual bamboo or bundled bamboo) with sleeves. A sleeve is mounted at each end of the bamboo. At one end there is a threaded sleeve, preferably with an external thread. At the other end there is a post sleeve, in particular with a mounting plate with drill holes, so that in a frame with openings for inserting the bamboo supports from the outside, the sleeve with external thread can be inserted on one side of the frame and screwed in and on the other side the mounting plate of the grating sleeve rests on the outside of the frame and the frame can be screwed, welded or riveted to the drill holes in the mounting plate. Additional sleeves can be mounted between the two ends of the bamboo support, which can be used to fasten and / or transmit force to mountable panels and surfaces such as photovoltaic modules.In particular, these sleeves can also contain additional connecting elements such as screw connections or clamps, whereby connecting elements are used in particular which enclose the sleeve and the bamboo contained therein and firmly connect them to the panel.

[0136] Fig. 19 shows only the prefabricated bamboo support from Fig. 18, which can be inserted into a frame. With several sleeves that completely enclose the bamboo and are filled with a filler.

[0137] Fig. 20a and Fig. 20b show an example of a connector element 55 according to the invention with a sleeve 72 into which a naturally grown round rod 56b, such as a bamboo stick or branch, is inserted. The round rod 56b is loose in the sleeve, i.e., with play. In the finished support structure, this round rod 56b is fixed, e.g., glued, in the sleeve 72 of the connector element 55. In variant 20b, the two sleeves 72 of the connector element parts are movable relative to one another, which may preferably not be necessary with a larger inner diameter of the sleeve 72, since the play is sufficient to compensate for the shape or bending of the naturally grown round rods 56b.

[0138] Fig. 21 shows a connector element 55 with sleeve 72 as before and a frame 50 or a fastening element with sleeve 72 (or a frame 50 with connector).
