Definitions

  • the invention relates to a method for producing a rod element as a construction element, wherein the rod element consists of a plurality of strips preferably made of bamboo and is at least partially formed as a hollow element, wherein the interior of the hollow element is at least partially formed as a groove, and a correspondingly produced rod element ,
  • Such a method for producing a rod element is already known from NL 8 402 779 A1 previously known.
  • a plurality of enclosing wooden parts are joined together, which are held together by intermediate and outer resin-pressed reinforcements.
  • the districts can be put together in various ways to the spatial shape of a cylinder jacket, so that they can be used, for example, as a ship's mast.
  • the wooden parts are attached around one or more discs shaped shaping templates around.
  • the wood parts may be required to a plate into which are then preferably milled V-shaped grooves, so that then the plate can be brought into a cylindrical shape.
  • Another comparable rod element is from the DE 20 2014 101 157 U1 previously known.
  • the invention is based on the object to provide a method for the production of rod elements with which such rod elements can be produced, which also suitable as a construction element for the construction of structures, trusses, grid structures or other spatial bodies and geometric bodies are.
  • the object underlying the invention is achieved in that the groove formation of the rod elements by means of a plastic introduced into the rod elements and / or resin, using a movable body through the interior of the rod element is realized.
  • the advantage over the previously known from the prior art solutions is that the corresponding rod elements are made of a natural and rapidly renewable raw material, namely bamboo, wherein the production of this rod element takes place by joining strips with a defined cross-section to a rod , which has a defined inner cross-section, since the internal formation of the rod element is realized as a groove by a movable molded body is moved through the interior of the rod element, wherein previously the interior of the rod element was provided with an introduced plastic and / or resin, which is brought by means of the shaped body in a defined shape, namely the shape of a groove, and then in this intended Form hardens.
  • the grooves formed in the interior of the rod element can also be realized by means of an inserted into the interior of the rod element inner tube, which is coated on the outside with a, preferably fiber-reinforced, plastic and / or resin outer jacket. After completion of the curing process of the outer shell forming materials, the inner tube can be pulled out against the background of its previous coating with a release agent from the rod member while retaining the outer groove forming the groove.
  • the above-described construction of the interior of the rod element causes a stiffening of the rod elements produced in this way, which accordingly have a higher stability and in particular as components have the required compressive and tensile strength.
  • Another significant advantage of the solution according to the invention is that, in contrast to the naturally grown bamboo, a uniform tube cross-section over an almost any tube length, as well as a precise wall thickness by the production of the rod elements according to claim 1, is achieved. Because the individual rod elements can be produced with a defined cross section and a defined wall thickness, the rod elements produced accordingly can be industrially manufactured, used and further processed.
  • the molded body which can be moved through the interior of the rod element is a movable piston.
  • the strips used to produce the rod elements have a trapezoidal cross section, so that the individual strips can be permanently connected to each other as intended to form a round rod element in the obliquely set longitudinal edges of the strips.
  • six or eight of the above-mentioned strips are connected by means of an adhesive bond to a closed rod member having a hexagonal or octagonal cross-section further.
  • the strips along their longitudinal edges are connected together in such a way that they complement each other to the above-described closed rod element.
  • the longitudinal edges of the strips to form the rod elements are flat, so that in this way a good adhesion of the adjacent strips in the region of these longitudinal edges to form an adhesive bond is ensured.
  • the configuration of the inner contour of the rod elements, by means of the movable molded body, may also be partially eingargbar in order to impress a defined inner contour, in particular in the end-side termination region of the rod elements, such as a three- or quadrangular or round inner contour, which in turn can be helpful if several Bar elements in the longitudinal direction successively with each other, for example by the use of in this inner contour insertable hollow body, to be connected to a corresponding outer contour.
  • an inner hollow body in the defined inner contour, in particular in the frontal inner contour of a rod element are inserted such that this devishohlköper has a projection with respect to the one rod element and on this supernatant a subsequent other rod member is analog pluggable, so that using the inner hollow body two bar elements are interconnected.
  • two rod elements can also be connected to each other by means of an angled or bent inner hollow body, wherein the angled or bent passage of the inner hollow body in the intermediate region between the two rod elements is arranged and thereby also a corner or curved connection between the two at this connection involved rod elements are produced.
  • a plurality of rod elements by means of one or more inner hollow body, which in turn may be provided with several connecting pieces, so branching to these multiple connectors, are joined together to form polygonal structures, grid structures, spatial bodies, geometric bodies or trusses.
  • the rod elements can also be connected to each other by means of suitable hollow body, wherein the hollow body used for the connection in this context are provided in the lying between the rod elements to be connected connection area in each case with at least one articulated connection.
  • articulated connections can be made within the scope of the invention, that is, room bodies that are variable in their outer shape.
  • rod elements according to the invention need not be prepared as a closed rod elements, but rather half-round or other semi-open rod elements can be produced within the scope of the invention, also by means of the strips used for the production of the rod elements.
  • wall-like structures or honeycomb-like wall structures can also be produced in that a plurality of the rod elements according to the invention are joined together along their outer contour to form composite rod arrangements.
  • structures or sections of structures can also be produced with the aid of the composite rod arrangements according to the invention.
  • the constructions according to the invention have the advantage that they are produced in a resource-conserving manner from a natural or at least largely natural raw material and, moreover, have a lower weight and easier processability than conventional constructions of stone or other solids.
  • open rod elements or closed half-cable elements can also be integrated into the mentioned composite rod arrangements.
  • the composite rod assembly can be planked on one or both sides, or be made immediately in a sandwich construction, wherein the inner layer is formed in each case by the above-described composite rod assembly.
  • the composite rod assembly can be supplemented with the intermediate layer of insulating material and / or reinforcing materials.
  • FIG. 1 shows in a perspective view of a bar element 1, which consists of a plurality of strips made of bamboo strips 2, wherein the strips 2 each have a trapezoidal cross-section.
  • the strips 2 are each connected to each other in the region of their longitudinal edges 3 by means of a suitable adhesive connection. After the strips 2 are manufactured with an industrial cutting process, it is ensured that the longitudinal edges 3 are formed flat to form a resilient connection and, moreover, the rod elements 1 produced by means of the method according to the invention are each provided with reproducible cross sections.
  • the rod elements 1 according to FIG. 2 be coated with a plastic and / or resin and in a further step, a movable piston with a round outer cross section, at least in sections, are passed through the rod element 1, with the result that a circular inner cross section 4 is impressed in the rod element 1, ie a groove is formed, which is also resilient after curing of the introduced composite material. Accordingly, the rod elements 1 according to FIG. 2 also a reproducible inner cross-section with clearly defined dimensions.
  • the polygonal pole elements can be processed in such a way that arise from the multi-edged bar elements 1 as such, which also have a round outer cross-section 5.
  • This can be realized by turning the polygonal tubes on their outside until the desired round outer cross section 5 has been created.
  • the existing in this context problem of a reduced due to the outer turning of the outer cross section of the rod member 1 wall thickness, as shown in FIG. 3 be remedied by the fact that in the interior of the rod element 1, a round inner tube is introduced, which is provided with an outer sheath.
  • the outer jacket is applied with the interposition of a release layer from the outside to the inner tube and usually consists of resin or plastic or of a composite material of these materials, in addition to glass, carbon or carbon fibers are further incorporated in this outer jacket for further stiffening in this outer jacket for further stiffening.
  • These fibers can be introduced in a simple manner in the form of a wound around the inner tube fabric mat in the outer jacket or else be incorporated as individual fibers in the longitudinal and / or transverse direction in the outer shell.
  • the inner tube After curing of the outer jacket, the inner tube can be easily pulled out of the rod member 1 due to the intermediate separation layer, which thus has a round inner cross-section, and due to the integrated fiber assembly has a higher rigidity, by the stiffness loss caused by the twisting of the outer cross section of the rod element was caused, compensated or overcompensated.
  • the outer surface of the outer cross section of the rod member 1 is reinforced by the application of a respective further bamboo strip 6 and only then the rod element 1 are turned off, until in turn a round outer cross section 5 is reached. This with the difference that the obtained in this way wall thickness of the rod element 1 with respect to the execution in FIG. 3 is significantly strengthened.
  • the rod elements 1 as shown in the Figures 1-4 can, if necessary, be reinforced and stiffened by means of suitable internal reinforcements, wherein, as shown in FIG. 5 a triangular inner tube 7 was used, which is preferably also made of bamboo and is produced analogously in that the bamboo strips for the production of the inner tube 7 in the region of their longitudinal edges 3 '- are connected to each other - for example by a suitable adhesive connection.
  • This inner tube 7 is introduced in the sense of a press fit in the rod element 1 to the stiffening and accordingly causes a higher load capacity of the rod element 1.
  • the interior of the rod elements 1 can also be filled with a filler, for example, foamed, in this context either only the interior of the inner tube 7 or the entire interior of the rod element 1 can be filled or filled with foam.
  • FIG. 6 also shows in a perspective view a not yet completed rod element.
  • rod elements 1 can be joined together by means of suitable connecting elements.
  • hollow body 10 which may again be bar elements 1,1 'according to the invention, but need not be inserted positively in the defined inner cross section of a rod element 1 in such a way that the inner hollow body 10 as shown in FIG. 7b) an overhang 11 with respect to the one bar element 1 is formed, before then analogously the other bar element 1 'is fitted onto the hollow body 10 and thus a connection of the two bar elements 1,1' according to Fig. 7c) is made.
  • the inner hollow body 10 can be more or less arbitrarily shaped to produce the connection between two rod elements 1,1 ', so for example as an angular element or as a cam element, so that even angular or curvy connections between a plurality of rod elements 1,1' as shown in FIG FIG. 8 are conceivable.
  • curvy connections can only be realized using special, at least not made of bamboo, fasteners, such as die-cast or produced in 3D printing.
