Definitions

  • the invention is directed to a system for the production of a framework Bar elements and with connecting elements for connecting the bar elements with each other, wherein the rod elements are designed as tubes and the Connecting elements have planar side surfaces which along Polyeder inhabit run and of which at least one, preferably at least two, provided with at least one recess.
  • the local connection body has the form of a Hollow cube with parallel to its edges, projecting obliquely outwards Flanges. Both the cube sides and the edge flanges are with Drilled holes to which to form a space frame tubes can be recognized. Their ends are squeezed flat and also pierced so that they are screwed to the holes of the edge flanges can be fixed. Thus, to build a truss with this system per bar at least two, possibly even four screw to press. This leads to the fact that with larger frameworks a huge amount of To make screw connections are what the prior art system very makes it seem impractical.
  • At least one with one or more Recessed side surface of a connecting element at least in the environment of the recess is formed as a flat flat body of the relevant recess is completely penetrated.
  • a connecting element of parts of an inserted tube to the Fixation is underlaid.
  • the entire connecting element be designed as a hollow body, so that its weight is minimized. among them the stability does not suffer, since the remaining surface especially at completely or predominantly enclosing the cavity in itself extremely stiff; On the other hand, the weight reduction causes especially for large Structures with a variety of fasteners a significant Discharge.
  • lateral Direction of movement of the assembled structural elements can be pretend different, eg. In a spatial direction parallel to the relevant pipe end side or side surface of the connecting element.
  • a relative rotation around the relevant Pipe longitudinal axis because this is one of the orientation of the elements in space is largely independent movement.
  • the elements are in each (rotary) position in an (indifferent) balance.
  • This Advantage can be used in particular in the context of the so-called. to create a structure that can be built up and dismantled with just a few simple steps.
  • a side surface of a connecting element at least two, preferably three or four, recesses, in particular openings are provided, which lie on a circular line whose diameter is about the Pipe diameter corresponds, so can each of these openings with exactly one extension on the front side of an attachable pipe correspond.
  • some or all of them may have one Extension associated recesses be formed so that the Total number of apertures per side surface of the connector may also be smaller than the relevant number of extensions on one end face a pipe.
  • a twist of a pipe in a framework always provides one Relative rotation with respect to both adjacent fasteners. Therefore, there is only one common direction of rotation for locking the two Give connections. While doing so with radially inward or outward Undercuts is unproblematic, because thereby the Arresting direction is not set, the latter is at tangent to the given pipe jacket oriented undercuts predetermined. Out For this reason, the invention recommends that the orientation direction of the Undercuts on the extensions of the two pipe ends mirror image with respect to a median plane extending transversely to the longitudinal axis of the tube should lie, i.e. have to lie in tangential undercuts pointing in the same (pipe) direction of rotation.
  • the individual extensions themselves must on the other hand, not necessarily mirror images of each other; you can For example, offset by an arbitrary (circumferential) angle against each other be arranged to special, structural conditions of a structure correspond to.
  • the extensions can cut out at the pipe ends be formed the pipe jacket, in particular by laser cutting.
  • This Machining process can be fully automated with commercially available machines and in be carried out in large quantities, resulting in a highly accurate and at the same time cheap product leads.
  • An undercut of an appendage which as an incision in an approximately radial with respect to the longitudinal axis of the tube extending surface area is formed, can take place simultaneously with the cutting of the extension. As a result, no additional operation is required for this, which is also has a cost-reducing effect.
  • each an elongated shape or at least one elongated Section which (r) runs along the common circular line.
  • a Such construction serves to lock a pipe by relative rotation about its longitudinal axis, wherein the inserted projections in the longitudinal direction of the Slide through openings or along the (longer) circumferential line.
  • the invention further provides that a connecting element of a single blank, preferably made of sheet metal, bent or several, respectively one or more side surface corresponding parts, also preferably made of sheet metal, is composed.
  • a connecting element of a single blank preferably made of sheet metal, bent or several, respectively one or more side surface corresponding parts, also preferably made of sheet metal, is composed.
  • both a possibly common Blank as well as several individual blanks each from a sheet metal be punched or cut out in particular with laser.
  • the Repeated folding of a single blank insuperable, prepare manufacturing problems, so that in this case a Manufacture of several parts is essential.
  • the flat body of at least two side surfaces is through be bent edges of these parts, which by assembling or -biegen parallel to each other and are connected to each other flat. When these edges go out to the outside of the finished fastener are bent, their connection after assembly due promoted their then exposed location.
  • the folded edges of the composite blanks or adjacent side surfaces are parallel to each other and thus adjoin each other over the entire surface, the bending angle ⁇ v between the bevelled edges and their original position in the plane of the respective side surface should be equal to or less than 90 °, if the contiguous polyhedral surfaces (without edges) meet along a convex edge (with an external angle ⁇ > 180 °) and the edges are folded outwards.
  • the collapsed or assembled side surfaces become then welded together, soldered or glued, especially in each case along its folded and flat edges.
  • an electric particular spot welding method is an electric particular spot welding method; the contiguous edges can be conveniently between two Electrodes introduced and of these during the welding process compressed and thereby aligned, so that a predetermined dimensions exactly corresponding connecting body is formed.
  • the invention is further characterized in that at least one with Recesses, in particular openings, provided side surface a quadrangular, preferably rectangular, in particular square base Has.
  • a quadrangular, preferably rectangular, in particular square base Has has.
  • various polyhedra are known, the (also) side surfaces with three, have five or six corners.
  • such connecting bodies are manufacturing technology consuming, because either the edge lengths of the pages would be comparatively large (triangular sides) or per side surface one larger number of folds would have to take place (five- or hexagonal Pages). Therefore, the invention provides, in the conception of a Connecting body emanating from a square side surface. For example, in this way connecting body with a belt from an almost arbitrary number of such, rectangular sides make the then closed with a flat top and / or bottom and thereby can be stabilized.
  • Other polyhedra are conceivable.
  • the invention can be further developed in such a way that the pipes and Connecting elements made of steel, in particular stainless steel, consist.
  • Steel is mechanically very stable and therefore gives such a framework a high Capacity; Steel can also be processed well and especially weld.
  • the framework 1 of FIG. 1 is incomplete and is intended solely to illustrate serve the principle of the invention.
  • both of joined side surfaces 5, 6 with each square base are composed. While that Connecting element 3 from a total of six identical side surface elements 5, the connecting element 4 comprises a total of eighteen with each other identical side surface elements 6.
  • All, shown side surface elements 5, 6 are original formed flat sheet blanks. These blanks have a light weight Cross shape. This arises from the fact that on all four sides of a square 7 each a rectangular or slightly trapezoidal, narrow edge strip 8 with a its longitudinal sides is formed. Since the free longitudinal side 9 of such Edge strip 8 is about five to ten times as long as a narrow side 10 this Marginal strip 8, the cross shape is barely recognizable.
  • connection node 3 are each two diametrically opposite edge strips 8 at identical angles ⁇ ⁇ bent, for example, twice by 60 ° and twice by 90 °.
  • the side surface elements 5 to the connecting element 3rd be composed by tilting each of a total of six Side surface elements 5, each with a bent by 90 ° edge strips 8 placed on a flat surface and then so on the rest it is assumed that a regular hexagon results in the plan view, with all edge strips 8 facing outward. Now there are two together bordering edge strips 8 parallel to each other and lie flat against each other; these are finally fixed together with a few welding points 11 to Completing the connecting element 3.
  • frontal plates instead of flat, frontal plates also two such side surface elements 5 between two diametrically opposite side surfaces 5 of the hexagon ring at the same Attached front side and connected to each other. It results from it two hexagon rings, which penetrate each other.
  • the connecting element has an octagonal basic structure. This results from folding the edge strips 8 of the side surface elements 6 by angles ⁇ v of 67.5 °, so that the edge strips 8 finally with the outer side 12 of a side surface element 6 each have an obtuse intermediate angle ⁇ ⁇ of 112.5 ° include. If these side surface elements 6 are assembled in such a way that their outwardly directed edge strips 8 lie flat against one another, then the (imaginary) extensions of the edge strip planes intersect in the interior of the connecting element 4 in its center.
  • Is such an octagon made and fixed by welding 13 can be converged on each end face of the same four to each other inclined side surfaces 6 attached and finally by a final element 6 to each connected to a roughly truncated pyramidal structure.
  • this structure is not completely closed - in the area of each mutually converging edges of the truncated pyramids remains open triangle - has this connecting element 4 because of his three-dimensional structure a very high stability. If necessary, could even in the gaps are inserted respectively triangular side panel elements.
  • each side surface 5, 6 of a Connecting element 4 can be used, even if it is not square is. However, a usable side surface 5, 6 must be greater than that Cross section of the pipe in question 2. Because for their attachment have the tubular rod elements 2 on their lateral surfaces 14 end extensions 15, for insertion in designed for this purpose openings 16 in the side surfaces 5, 6 of a connecting element 3, 4 are designated. The openings 16 Accordingly, lie on a circular line with the diameter of the tubular Bar elements 2 and therefore require a correspondingly large sized side surface 5, 6 of a connecting element 3, 4th
  • the extensions 15 are from the tube jacket 14 cut out, for example, with a laser. They therefore have a cross section with a curvature corresponding to the pipe jacket 14. This arched cross section is also found in the corresponding with these extensions Openings 16 of the side surfaces 5, 6.
  • Each opening 16 has Accordingly, an arcuate course with a constant width, about the Strength of the tubular jacket 14 corresponds.
  • the length along the arc can are chosen to be variable, but is preferably significantly larger than the width, For example, 2 to 20 times as long, preferably 3 to 15 times as long, especially 4 up to 10 times as big.
  • the cross sections of the extensions 15 and the correspond Openings 16 each other like a transition fit, so that the elements 2, 3 can be put together without jamming, but then if possible have no game.
  • the extensions 15 are each with a lateral undercut 17 provided.
  • the (tangential to Pipe jacket counted) base of an extension 15 can be by a Rewrite rectangle.
  • Whose measured parallel to the pipe axis Longitudinal extension is greater than the thickness of a side surface element 5, 6, for example, two to four times as long, in particular about three times as long.
  • tangential direction (with respect to the tube 2) has an extension 15 a Maximum extent, which is preferably greater than its axis-parallel length, For example, 1.5 to three times as large, in particular about twice as large.
  • the undercuts 17 have approximately the shape of a slot in the relevant narrow side 18 of an extension 15 whose width is about the strength a side surface element 5, 6 corresponds, and its depth preferably about two to five times its width. Preferably, one is aligned Side surface of the slot-shaped undercut 17 with the adjacent Area of the tube end 19.
  • the width of the slit-shaped undercut 17 at least in the region of the slot bottom be minimally smaller than the thickness of a side surface element 5, 6, so that during a locking rotation, the nose 20 is bent up elastically and the restoring force acts as a friction-increasing normal force.
  • Truss 1 additionally by welding, soldering or gluing the tubular rod elements 2 with the connecting elements 3, 4 stabilized become.
  • the highest stability is indeed one the end faces 19 of a inserted pipe 2 completely circumferential weld - to avoid but unwanted loosening can already individual welds be enough.
