Definitions

  • the invention relates to a construction system with rod elements which have a plurality of coupling connections at at least one of their ends and can be connected by means of angular connecting elements to be arranged in nodes.
  • a wide variety of construction systems are known for the creation of essentially linear space constructions, in particular showcases for trade fairs, exhibitions and department stores. They comprise a plurality of rod-shaped components and various coupling or connecting elements, which are used to connect several components to one another.
  • a set of components for the construction of load-bearing metal structures is known from German utility model G-66 04 584.
  • a knot angle is used in connection with supports and struts made of tubular profiles with a square or rectangular cross-section.
  • the node angle essentially consists of a central cuboid component with three or more connections, onto which the tubular profiles can be attached.
  • the metal profiles converging in a node are therefore all connected by a single node element.
  • a cross connection, with which four flat profiles can be connected in one plane, is known from DE-OS 1 559 241.
  • the hollow profile is divided into three by two webs separated cavities.
  • Right-angled core pieces can be inserted into the cavities.
  • the cross connection is e.g. B. created in that two adjacent, mutually perpendicular hollow profiles are connected by a Kern ⁇ piece. Instead of four core pieces, a single cruciform can occur.
  • US Pat. No. 4,136,984 discloses a clamp connection with which tubular elements can be connected at right angles.
  • the pipes are attached to an elbow by metal brackets.
  • connection systems are neither versatile nor aesthetically satisfactory. So z. B. only strictly right-angled construction systems can be implemented. Another disadvantage is the fact that a number of bar elements specified by the system must converge in a node.
  • the object of the invention is now to provide a construction system of the type mentioned, which has a high degree of flexibility with a small number of different individual parts.
  • the solution is that in a construction system mentioned at the outset, the coupling elements for connecting the rod elements in a plurality of different angular positions in each case. can be fixed in the coupling connections.
  • the construction or frame system according to the invention essentially comprises only two construction elements, namely a rod and a connecting angle. These two basic elements can be used to build not only right-angled but also non-right-angled support structures. With the help of plates of suitable size, racks, room dividers, cupboards and the like can be realized.
  • the coupling elements are generally visible. However, they are not disturbing, but are aesthetically integrated into the overall appearance.
  • the coupling elements can be fastened in the coupling connections in more than two angular positions.
  • the system becomes particularly variable when not only 90 ° positions but also intermediate positions are possible. If the coupling connections are rotationally symmetrical (circular), in principle any angular position can be realized. If a high stability of the system is required, several defined locking positions can be specified.
  • the coupling connections are then preferably polygonal.
  • An aesthetically particularly appealing embodiment is characterized by bundle tubes as rod elements.
  • the bundle tubes are formed from a plurality of cylindrical individual tubes which are essentially connected to one another over their entire length, each individual tube having a coupling connection at each end. Two, three and four bundle tubes are preferred.
  • the individual tubes are arranged at equal distances around the central axis of the rod element. In the case of a three-bundle tube, viewed in cross section, the individual tubes form e.g. B. an equilateral triangle. In the case of a four-pipe, the individual pipes are preferably diamond-shaped or square in cross-section.
  • the coupling elements advantageously have either the same cross section as a single tube or a much smaller one.
  • the coupling element (angle) has essentially the same diameter as a single tube, it is advantageous if a tapered area is formed in the transition area between the single tube and the angle. This not only has an aesthetic effect, but is also suitable for attaching a clip for fastening intermediate plates or the like.
  • the tapered area can e.g. B. be formed by a bolt on which a union nut is rotatably and captively mounted.
  • the union nut mentioned can be screwed onto a corresponding threaded bolt of the angle or rod to be connected. In this way, a rotatable connection between the coupling and rod element can be realized.
  • the coupling element can have a plate-shaped web on the inside of the angle.
  • a corner of a wall or base plate can be supported on the web.
  • the two arms of the angle may or may not be brought together in the angle tip. However, this is not just a question of aesthetics. If the angle is formed by two pieces of pipe that unite in the corners, then in principle dustproof showcases can be put together. If the connection between rod and coupling element can be rotated, display cabinets and the like can be made with integrated doors or flaps.
  • the rod elements are cylindrical in cross section and at the end have several, in particular four, coupling connections for coupling elements.
  • the diameter of an arm of the angle (coupling element) is less than half the rod diameter.
  • a clamping body split into several, in particular four, clamping jaws is provided at the end of the rod, which can be clamped together by a screw sleeve, so that the connecting elements used are all clamped at the same time.
  • At least one transverse bore can also be provided, into which locking bolts can be inserted to hold the angles.
  • the coupling elements are characterized by a particularly simple, in particular angular, structural design and, because of the force distribution achieved in the nodes of the room structure, can be produced inexpensively using less material.
  • the possible combinations in the formation of the coupling body from individual coupling elements also advantageously ensure a considerable range of variation in the assembly of a desired spatial structure.
  • individual coupling elements are omitted, there are additional degrees of freedom of the construction with regard to the pivotability of parts of the construction about individual spatial axes which cross adjacent node areas.
  • the introduction of plate-shaped components can be realized with a high form fit.
  • the rod-shaped elements are designed as hollow profiles, which have a plurality of individual, separate chambers.

  • the rod-shaped one Elements a node are formed, from which the rod-shaped elements extend to mutually ordered directions.
  • the chambers of the hollow profile of the rod-shaped elements have a rectangular, square or circular cross-sectional profile.
  • the pins of the coupling elements are of a stepped design, with respect to the external dimensions of the legs. As a result, essentially smooth surfaces are created in the area of the insertion points, which contribute to improving the visual impression of the entire construction. This also applies if adjacent chambers of the profiles - at least in some areas - only adjoin one another with simple wall thickness. Furthermore, it is for the assembly is advantageous if the pins are designed as removable parts to be connected to the coupling element.
  • connection device with a union nut has, for. B. the advantage that a characteristic taper can be used to hold clips that in turn hold plates or for z. B. colored marking can serve. It is optically important that a connection is largely invisible in the representative area, which is ensured with the aid of the variants described below. Another advantage is that it can be installed regardless of the direction, as each rod can be installed or removed at any point without constraint.
  • connection is made using a union nut, which is located either at the rod end or at the corner element.
  • the connecting part located at the end of the rod is screwed in, hammered in or glued, soldered or welded.
  • the necessary bolt-head-like expansion to hold the union nut can also be done by widening or compressing the bolt.
  • the union nut in turn, is screwed directly onto the matching threaded part of a connecting bolt or onto the corner element.
  • the bolt which is screwed or inserted into the rod can have a stop part which is adapted to the diameter of the tube and which is homogeneous or mounted or welded, glued or soldered.
  • the stop can also be achieved by reducing the cross section. gen.
  • a profiling located on the end face of the union nut serves to hold tools which have a complementary profile and thus ensure that the union nut is securely tightened.
  • Clips for receiving wall and floor panels or covering or marking clips are advantageously designed such that they engage in the tapered part of the connecting device of the corner element or the rod-shaped component with a positive fit.
  • the clips can be designed such that they receive the plate-shaped elements either centrally or flush with the uppermost edge of the plate-shaped structure.
  • one-piece components can act as two clips.
  • connection possibility is to screw a bolt held in the corner element by a glued-in, welded-in, soldered or assembled sleeve through a driving sleeve into the tube part.
  • the bolt sleeve and the inner part of the driving sleeve must have profiles or openings or have other arrangements which ensure that the bolt is carried along and possibly make it impossible to lose.
