Definitions

  • the invention relates to buoyant, essentially flat trusses and modularly composed, buoyant 3-dimensional support structures, for example as a support structure for floating platforms, for example for the uprising of solar panels and wind turbines, or as a support structure for wave power plants.
  • Floating platforms such as platforms supported by floating bodies or pontoons and the like, are widely known in the prior art. Many of these structures are complicated in their construction and are therefore often assembled on land in order to be brought to their place of use in the assembled state. This particularly limits the size of such platforms.
  • Support structures with a larger area, which are assembled offshore, are often difficult to manipulate or maneuver, especially when they are on the open sea, i.e. in the sea.
  • the construction “offshore” in particular causes a high use of resources and thus costs, which can be very high with these extensive support structures.
  • the manufacturing and assembly effort should be reduced to a minimum, especially the assembly effort offshore.
  • With the support structure according to the invention it should also be possible to provide a robust, floatable support structure that can be flexibly adapted in terms of its dimensions and load-bearing capacity.
  • the object is achieved by a buoyant, essentially planar framework according to claim 1.
  • Advantageous embodiments are specified in the dependent claims 2-7.
  • the object according to the invention is further achieved by a buoyant truss structure according to claim 8 or 9.
  • Preferred embodiments of these truss structures are indicated with the dependent claims give.
  • floating bodies are also specified according to claim 14, preferred further developments being specified with the dependent claims thereon.
  • a wave power plant is also given, which is modularly constructed from a plurality of truss structures according to the invention, which in turn are modularly constructed from the trusses according to the invention.
  • the floating bodies mentioned above are used to convert wave energy into electrical energy.
  • the base unit according to the invention forms a framework, which is provided for the modular construction of an offshore framework structure and is essentially flat.
  • the framework according to the invention has a first bolt functioning as a floating body and a second bolt which are supported parallel to one another by means of two lateral posts.
  • the framework can be held diagonally in shape or tensioned using two straps.
  • connecting elements with flanges are arranged at the end of the bolt. If the first and / or the second bolt is constructed from a hollow body, the flanges close the bolt in a fluid-tight manner, so that an air volume received therein generates a corresponding buoyancy force. When using metallic materials, this can be done, for example, by welding the flanges to the bolts. Other connections customary in the art, such as screwing or gluing, possibly with seals, are also included in the inventive concept.
  • at least the first bar is designed as a fluid-tight hollow body, at the ends of which the connecting elements can be fastened.
  • the bolts together with the connecting elements attached to them at their ends form an assembly of the framework according to the invention, which is particularly preassembled on land.
  • the connecting elements have in addition to the flanges Aufnah men for tying the post to the bolt transversely to the longitudinal direction of the bolt in order to keep the bolt parallel spaced.
  • These lateral posts, which are essentially aligned perpendicular to the bars, are preferably only plugged together with the recordings. More preferably, this is done without the aid of tools, so that all known types of rigid or articulated plug, clamp, clip connections are included in the concept of the invention, which are suitable for connecting the posts to the connecting elements without tools.
  • tapes which have tensioning devices. These tapes can be fastened to fastening means on the connec- tion elements and fix the framework diagonally or keep it in the substantially rectangular shape.
  • straps includes tension and lashing straps, as well as struts with tensioning devices, for example with corresponding Unks right-hand threads, ropes, etc.
  • bolts are used transversely to the longitudinal direction of the latch and transversely to the longitudinal direction of the posts in the connecting elements, the bolts are more preferably rotatable, but are axially fi xed in the connecting elements by the bands inserted therein.
  • the lattice struts designed as bands are divisible on the clamping device and each have a collar at the end opposite the clamping device, the diameter of which is greater than that of the transverse bore of the bolt received in the connecting element.
  • the framework according to the invention is scalable, since when the transoms and / or posts are lengthened, in addition to the length of the framework diagonals, their angle also changes.
  • the bolts rotatably accommodated in the connecting elements are unnecessary, since the fastening means for the straps are designed, for example, in the form of a lead-through, an eyelet or a slot.
  • a framework according to the invention can be held in shape or together by simply tying the bolts with connecting elements to the posts and inserting (divisible) straps into rotatable bolts with transverse bores, using clamping devices alone.
  • the first bars are buoyant or function as a float. In this way, they generate a buoyancy force that reduces, balances or even exceeds the weight of their own weight in water.
  • the buoyancy force of the first bolt is so high that a framework can be held floating on a water surface, in other Ausure approximate forms the buoyancy of the first bolt is lower, and additional floating bodies can be arranged by, for example, in an extension of the posts on the framework.
  • the truss according to the invention can therefore preferably be built up as an assembly, for example on land, and can be created on land or offshore to form a truss structure, or be moved “offshore” to expand a truss structure.
  • an offshore support structure module can be assembled from several trusses according to the invention on land or near the shore and, for example, brought to its place of use by means of a tug, where it can be connected to further offshore truss structure modules. More on this below.
  • the buoyancy of a framework according to the invention can, as already indicated above, be ensured by the design of the first bolt as a hollow body, which is fluid-tightly sealed with the connecting elements, or which is designed as a fluid-tight hollow body that can be attached to the connecting elements according to the invention.
  • the first and second latches can have different cross-sections or different diameters, or be made from different materials, since the second latch does not have to contribute to the buoyancy force, even if this is feasible. This is especially true in applications in which the trusses according to the invention are aligned vertically in a support structure, with the first bars forming the lower bars for example.
  • the first bars floating on or just below the surface of the water are decisive for generating a buoyancy force.
  • the diameter of a first bolt it is therefore conceivable to design the diameter of a first bolt to be much larger than the diameter of the other, second bolt, in order to save weight, for example.
  • the two bars it is also conceivable to design the two bars as identical parts, since then the connec tion elements, four of which are installed in each framework, can be designed as identical parts without adapter pieces being required. Possibly. are then required to generate sufficiently high buoyancy forces, the arrangement of further floats in extension of the Pfos th or on the bars.
  • the first bar generating a buoyancy force is made, for example, of a plastic or plastic composite Material can be produced, wherein the other parallel (upper) second bolt can consist of a metallic material and, for example, has a cross-sectional shape of a double T-beam and is further made, for example, of seawater-resistant aluminum.
  • all materials can be used that can be used in the industry to generate a buoyancy force, such as hollow bodies, materials with a density lower than that of water, in particular salt water.
  • foamed materials that surround, for example, a solid core of the bar, which is necessary for reasons of strength.
  • a floating body can be attached to the frameworks, for example in extension of the posts that spaced the two bars parallel to one another.
  • a fastening of a floating body halfway between the two connecting elements is also included in the concept of the invention, as is the arrangement of two or more floating bodies on top of each other on the framework that is preferably floatable alone.
  • the connecting elements have an asymmetrical shape with respect to the longitudinal direction of the bars, with an extension being formed on one side and a bracket on the opposite side , so that the extension of a connecting element of a first framework can be connected by means of the holder of another connecting element of a further, two-th framework.
  • the connecting elements can thus be designed as identical parts at all corner points of the framework according to the invention. Since always two adjacent connecting elements of two frameworks of a kind of male-female connection can be connected.
  • One embodiment of the invention has extensions on the connecting elements into which a connecting eye is introduced, into which a connecting bolt can in turn be placed.
  • screwing points are provided on the opposite side of the connecting element for Hal extensions that can fix the respective connecting bolts in the connecting eye of an adjacent connecting element in the axial direction.
  • the inventive and possibly only floating trusses can be used to form a floatable three-dimensional offshore truss structure, in particular to a 3-dimensional truss structure module according to the invention in the form of a straight triangular prism or a straight square or polygonal prism using suitable Fasteners are assembled. Characteristic of such straight prisms are their congruent base and top surfaces. According to the invention, the trusses described above form the side surfaces of such offshore truss structure modules as basic assemblies according to the invention.
  • the trusses in the offshore truss structure modules according to the invention are perpendicular, i.e. vertical to a water surface, are aligned, with the first bars floating in or on the water.
  • These truss structure modules which in particular form modular base bodies for planar support structures, for example to build a large-scale truss structure, can be put together both on land and at sea, since the trusses are inherently rigid and braced, making them simpler can be transported, assembled and manipulated as their individual parts. This is especially true if the trusses are to be joined together when there is a swell.
  • a truss structure formed from three trusses according to the invention represents the smallest module, a straight triangular prism.
  • the first bars span an approximately triangular base area, the second bars spanning a triangular top area that is congruent therewith. Since the three trusses are arranged vertically in this case, the side edges of such a triangular prism are formed by two lateral Stan conditions of two adjacent trusses.
  • the trusses are connected via the connecting elements. Specifically - as already stated above - for example via to the Connecting elements formed extensions with connecting eyes, in which connec tion bolts can be used, which are held by brackets, which are for example screwed to the adjacent connecting element. Due to the straight triangular prism structure, such a module is inherently stable and does not require any tension in the respective base or top surface, although such is conceivable.
  • trusses according to the invention are connected to one another in a vertically upright position, a substantially cuboid structure results, the vertical side edges being formed from two lateral bars of adjacent trusses.
  • the first bars and the second bars each form a substantially rectangular base or top surface.
  • adjacent trusses are connected to one another by means of the connecting elements, as already described above.
  • the connecting bolts of the individual connecting elements can have transverse bores into which connectors provided with clamping devices can be inserted in order to brace the frameworks with one another, for example in the base area as well as the top area. If the transverse bores are designed as inclined bores, connectors in the room diagonal, i.e. from a connection point in the base to a connection point of the top surface, which is not part of the same framework, are connected.
  • the connecting bolts rotatably in the connec tion elements so that the three-dimensional offshore truss structure module built up from preferably scalable trusses is also scalable.
  • straight triangular prisms or straight quadrangular prisms or straight polygon prisms which can form an offshore truss structure module of an extensive supporting structure, are created.
  • individually designed supporting structures can then be built depending on the application, which can represent platforms or support support devices for renewable energies or maintenance platforms or for wind turbines or drilling rigs.
  • the frameworks according to the invention can also be used in supporting structures for leisure bathing platforms or as equipment or break platforms for dives.
  • the field of application of offshore support structures according to the invention is not limited to this, so that, for example, driving bridges or the like are also conceivable.
  • floating bodies can additionally be attached to or under the first bolts provided for the buoyancy.
  • appropriate recording devices for handrails or lugs for floating bodies in extension of the post, with which the truss structures can be supported at the respective connection points / nodes.
  • four floating bodies can be arranged on a cuboid lattice structure at the respective four corners of the rectangular base, with a higher number of floating bodies divisible by four being possible.
  • holding rods can also be attached to the upper counter or corner points of the truss structure modules in order to attach further structural elements for holding devices to them.
  • floating bodies are preferably used which have a torus-like structure made of torus segment-like pontoons.
  • a torus-like floating body preferably has a large number of similar torus segment-like pontoons.
  • Each of these toroidal segments shows, on its essentially flat / planar side surfaces, connecting means, with which pontoons with a shape similar to pieces of cake can be connected to one another in an axially and / or radially form-fitting manner.
  • a preferred type of connection in accordance with the invention is the formation of tongue and groove connections.
  • the floating bodies preferably used according to the invention are thus put together like pieces of cake, with the center of the torus, i.e.
  • receptacles are designed to provide a connecting component, for example for connection to the connecting elements of the nodes of the truss structures.
  • On the outer periphery of the individual pontoons holding means are provided with which the individual segment-like pontoons are held together so that they are secured against drifting apart.
  • these are belts which engage in circumferential grooves of the toroidal segments and thus prevent the toroidal segments from drifting apart.
  • a torus - also within the meaning of the invention - is a body that is formed from a closed contour, essentially formed from convex lines, which rotates about a toroidal axis of rotation at a distance therefrom.
  • the contour made up of convex lines for example, is a circle - which in this special case leads to a “donut” shape.
  • any other contour including concave areas can be used according to the invention, which rotates at a distance from the toroidal axis of rotation to form a central toroidal eye around it.
  • the directions given below, such as axial, radial or circumferential, therefore relate - unless otherwise stated - to the torus axis of rotation.
  • a pontoon forms a torus segment of such a torus, i.
  • a complete torus-like floating body can be built up.
  • the number of torus segment-like pontoons required to form a complete torus-like floating body is irrelevant for the idea of the invention.
  • Each pontoon can swim on its own and represents, for example, a closed hollow body.
  • the floatable torus segment-like pontoons according to the invention have suitable connecting means on the essentially flat side surfaces for positively locking, axial, radial and / or oblique radial connection of adjacent pontoons.
  • flat side surfaces are preferred here, since a good form-fitting and force-fitting connection of adjacent pontoons can be achieved in this way, in particular in the axial direction of the torus rotation axis.
  • the invention provides holding means on the radially outer pontoon surfaces in order to connect adjacent pontoons to one another in the circumferential torus direction and / or in the radial direction.
  • the inventive arrangement of connecting means on the side surfaces and holding means on the radial outer pontoon surfaces the individual torus segment-like pontoons can be put together to form a floating body according to the invention, which has a central torus eye. This results in a simple removal option in the radial direction for the dismantling of a single torus segment-like pontoon without the entire floating body having to be dismantled.
  • these holding means can be a ring, in particular a metal ring or also a belt, for example an endless belt, which can be inserted / snapped into the holding means around the pontoons.
  • a torus segment-like pontoon according to the invention has receptacles on the radially inner pontoon surfaces, in which a further component, ok
  • a pontoon carrier can be included.
  • a pontoon carrier is preferably partially positively connected to each individual pontoon and thus also to the entire floating body in a planar manner, so that forces that act in the axial direction of the torus axis of rotation can be easily transmitted.
  • a planar connection / mounting of the pontoon carrier in the torus eye ensures that forces acting on the floating body are not transmitted selectively to the individual pontoons.
  • other devices that may be required for the functioning of a wave power plant such as a lifting rod, be fastened in the usual way.
  • a torus-like floating body can thus be assembled in a simple manner from the torus segment-like pontoons according to the invention, which float has a compact shape and structure.
  • the compact shape gives it the torus-like appearance
  • Float a high stability and a high level of robustness In addition, such a torus-like floating body can, in the event of damage to a single torus-like segment, i. a pontoon can be repaired in a simple manner by replacing the damaged pontoon. A full replacement of the

  • the torus segment-like pontoons according to the invention are manufactured from plastic in the rotary melting process, in the blow extrusion process or in the RIM process, the production of components with internal cavities being possible in all three processes.
  • the manufacture of solid floats is also conceivable.
  • a cost-effective process results which, with a relatively moderately simple basic shape, makes it possible in a cyclic process to produce a large number of pontoons according to the invention in series.
  • the manufacturing processes mentioned above are industrially mature processes familiar to the person skilled in the art and need not be explained in more detail in the context of this description of the invention.
  • the pontoons according to the invention are also preferred to manufacture from a plastic, which is particularly implied in the blow extrusion and the RIM processes.
  • the pontoons according to the invention can be produced as hollow bodies with the rotary melting process as well as with the blow extrusion process
  • pontoons according to the invention can optionally also be produced from aluminum, which, however, requires a special aluminum alloy when used in seawater.
  • plastics are - as unfortunately also the environmental problem shows - more seawater-resistant and therefore preferred for use in torus segment-like pontoons according to the invention.
  • Another preferred property of plastics is that their properties in terms of elasticity, elongation at break, notched impact strength, etc. can be better adapted to the respective application needs than is possible with other materials such as wood, metals or textiles.
  • At least one essentially radially, axially or in the radial direction obliquely extending groove is arranged on a soflä surface as a connecting means to a side surface of an adjacent pontoon, which in an opposite, essentially complementary tongue on the flat connection surface Ver of the neighboring pontoon can intervene in order to achieve a positive fit between two neighboring pontoons.
