Definitions

  • the invention relates to a node for connecting a plurality of beams in a structure, in particular for connecting bars in a framework, use being made of a connecting device which is attached to the edge or end of the beam and has a base body which relates to one or more the support axis and / or side has inclined wall sections for resting within the knot on wall sections of adjacent, similar connection devices or other bodies, and the superimposed wall sections are interspersed and held together by connecting elements.
  • the invention relates to a carrier connection device which is particularly suitable for forming this node, by means of which a plurality of carriers of the supporting structure, in particular rods of a truss, are connected to the node;
  • the connection device is based on a base body which has one or more wall sections which run obliquely with respect to the support axis and / or side and which are each penetrated by at least one access channel which runs in the base body and which is for receiving and for Intervention or engagement is formed by knot connection elements (eg screw elements).
  • Node and carrier connection devices of approximately this type are known from the previously published patents FR 2 143 644 and EP 0 031 804.
  • connection parts are manufactured as separate knot-forming parts, which increases the assembly effort and the necessary screw connections.
  • the walls of the connecting parts are so thin that these penetrating internal threads cannot be effective; this requires additional parts and assembly work for separate lock nuts in nodes.
  • the problem on which the invention is based is raised to create a node structure and / or a connection device for connecting a support to a node for net-like structures, which increases the ease of handling and assembly, reduces the overall weight of the structure, a compact design enables and the number of necessary connecting elements are minimized; At the same time, the customary flexibility in the design of different spatial structure shapes and movements should be maintained or increased.
  • each connecting element is received in an access channel and / or leads, which runs from the inclined wall section inside the base body to the outside of the knot and consequently ends outside the knot area.
  • This provides access to the connecting elements, for example screw elements, which can be of a slightly linear design and thus enables several carriers, for example rods, to be electrically screwed to one another.
  • the access channels guided according to the invention result in a cavity which is accessible outside the node area and still in the area of the beam or rod end or edge, from which the connecting elements can be actuated manually, in particular mechanically, in particular by machine, in particular rotatably.
  • two base bodies of two similar connection devices each lie with their inclined wall section together on an intermediate body, the wall section of which lies against the inclined walls and lies in a plane that corresponds to one side or the central axis of the support. in particular runs parallel to it or forms a common plane.
  • These intermediate bodies can be, for example, spacers, clamping jaws or other supports (e.g. rods) with (internal thread) bores and without the specifically inclined wall sections which are connected to the structure node either at a fixed angle or in an articulated manner.
  • a carrier connection device with the features mentioned at the outset is also proposed, which is characterized in that at least one access channel to the assigned wall section runs from a plane which corresponds to the side wall of the carrier to be connected, which is the node not closed turns.
  • the connection device By equipping the connection device, the end of the beam or rod in the node connection area can be designed in such a way that it can be directly fastened to one another there with intersecting screw or other connecting bolt axes. Because of the abutting sloping wall sections, there is the possibility of orthogonally connecting two beams to one another. The need for separate, central node parts is eliminated.
  • the connection can instead be brought about by direct inclined screwing of the supports in their respective end region.
  • the carrier ends or edges have cavities which form channels for screw connections into which tools can be used to penetrate outside the knot area.
  • the wall sections arranged obliquely to the support side or axis or plane of symmetry are arranged prismatically with respect to one another at such an angle and thereby expanded that the access channel of the one wall section does not affect the other wall section when it extends in a straight line and therefore does not affect it is not disabled.
  • a special design of the basic body in the form of a saddle roof is conceivable, from the apex (gable) of which a connecting sheep leads to the end face of the carrier.
  • the base body is made from a solid workpiece, which preferably has a cross section corresponding to the carrier to be connected, the access channels being able to be produced with little manufacturing outlay by means of bores which are oblique with respect to the base body symmetry axis.
  • the connecting device in particular the base body thereof, is particularly advantageously formed in one piece with the body of the support or rod and / or is structurally integrated in such a way that a (one-piece) node connection end is formed for the support.
  • This makes it possible to design flat and spatial structures without separate node elements, which are inexpensive with only one standard beam or rod type and can be screwed on mechanically and so quickly, for example, using conventional hexagon socket head cap screws according to the invention are mountable.
  • a structural integration is also to be understood when the aforementioned massive workpiece is welded to the front end of the support, which for example has a hollow profile.
  • a variety of geometric shapes can be used for the base body.
  • Rounded shapes or angular shapes with at least rounded corners have the advantage that intermediate bodies, for example diagonal struts, which are arranged between two connecting devices according to the invention, still have sufficient play for pivoting.
  • Polygonal shapes with flat support sloping walls result in a form fit when they are in contact with correspondingly flat wall sections, so that such a node can absorb torques.
  • six carriers can be connected to each other orthogonally in a node.
  • additional channels are provided which preferably penetrate the base body diametrically without an inclined support wall section affect.
  • these additional channels are arranged in such a way that they penetrate a plane, preferably vertically, which is spanned, for example, by two access channels assigned to the inclined support wall sections. If a support, which is provided with such a connection device with both access and additional channels, is rotated through 90 ° about its associated longitudinal axis, it can then be clamped between two oblique wall sections, each with an adjacent, similar connection device, or pivoted about connecting bolts be articulated.

For example, the force exerted by the sprag is on Another intermediate body (rope or rod) can be set depending on the application.
  • the bearing surface of the sloping wall section runs at an oblique angle with respect to the sides of the base body and / or carrier not lying in the node area. If, for example, two immediately adjacent sloping wall sections form a common apex edge, this runs at an angle greater or less than 90 ° with respect to all other planes of symmetry or outer sides of the base body or carriers attached to it. It goes without saying that the longitudinal axis of the access channel and / or the connecting element need not necessarily run perpendicular to the contact surface of the oblique wall section penetrated by it or to the other side surfaces of the base body or carrier.
