Definitions

  • the invention relates to a lattice girder for trusses with two spaced-apart belt profiles which are connected to one another via stiffeners, the belt profiles being provided with pairs of radially running openings and the stiffening being rods which run alternately in the diagonals and with their bent ends into one Opening are fixed engaging.
  • Space trusses are used as fast construction elements in a wide variety of areas. For example, they are used in exhibition construction to quickly set up exhibition stands.
  • the overall construction results from assembling and connecting individual elements, such as rods, nodes and bars.
  • the latter are flat, but also in terms of composition, spatial support structures with a cross-section of square shape or as an equilateral or isosceles triangle.
  • the sole object of the present invention is the further development of the known lattice girder, which consists of two spaced-apart belt profiles, between which stiffening coils running in alternating directions run and which are welded to the belt profiles.
  • a device of the generic type has become known from WO-A-86/05537. The ones shown there Connections between the bars and the belt profiles is relatively time-consuming and therefore costly to produce, since a direct connection between the ends of the bars and the belt profiles has to be established.
  • the invention has set itself the task of creating a lattice girder that is inexpensive and quicker to manufacture.
  • the lattice girder is consequently formed from two belt profiles, usually running parallel to one another, between which bars are arranged for stiffening and stabilization, which as a whole result in a flat component.
  • Each of the bars runs diagonally, their direction alternating, so that the result is an approximately zigzag course, due to the fact that the openings are each arranged in pairs, ie adjacent and parallel to each other, each belt profile a larger number of such Pairs.
  • the openings acted upon by the ends of the rods are offset.
  • the lattice girders are connected to one another or to girders in a manner known per se via connecting elements to be attached to the ends of the profiles, and the space trusses are thereby produced.
  • a support surface on the belt profile is advantageous, which is produced in that a deformation is carried out at right angles immediately before the end, which is bent relative to the axial direction of the rod.
  • the result is a step-like contact surface that clings to the opening on the edge side.
  • the rods are inserted with their curved ends into the openings of the belt profile and, due to the paired arrangement of adjacent rods, are detachably fixed by an attachment head which is in contact with them from the outside and is attached to the belt profile.
  • the connection can be made specifically via a screw, a pin or the like.
  • the advantages achievable with the invention are significant in several respects: With regard to the production, it is crucial that a dry assembly is possible, ie that all elements are individually manufactured beforehand and only finally get their final shape through assembly. A post-treatment, rework or surface refinement as required by welded joints is not necessary. The production is considerably simplified in this way.
  • the lattice girder receives high rigidity due to the special shape of the ends and the transmission of high tensile and compressive forces via the bars. In the case of detachable fastening of the belt profiles to the bars, there is the possibility of subsequent disassembly into the individual elements and to facilitate transport and storage.
  • the belt profile is a tube or a square, it is advisable to choose the length of the rod equal to this diameter. After insertion into the opening, the rod will be supported on the end face and from the inside on the belt profile and will thus be able to derive forces.
  • fixation and support are obtained at the lowest point by chamfering the rods at the end. Movements in the radial plane are prevented.
  • FIG. 1 shows a lattice girder in its entirety. Between two parallel girder profiles (1) of the same length, the bars (2) are in the diagonal, but in alternating directions arranged and attached to the belt profile (1) each with the end region. At the end of the belt profile (1) there are connecting elements (3) and at the end each end (4).
  • the belt profile (1) is a tube with a pair (5) of two openings, in each of which a rod (2) engages. In between there is another opening (6) into which the pin (7) is later inserted. The end of the rod (2) is bent over, engages radially in the belt profile (1) and lies on the end face from the inside against the wall opposite the openings (5), (6). The tip (8) is chamfered. After leaving the openings (5), the rod (2) is shaped at right angles in a short area and in this way forms a contact surface on the outside of the belt profile (1).
  • the rods (2) are fastened in such a way that the rods (2) are inserted into the opening (5) of the belt profile (1) as far as they will go, then a fastening head (9) is placed over the opening in between (6) to be inserted pin (7) is determined.
  • the fastening head (9) is a form-fit Profile (2) and belt profile (1) enclosing profile.
  • the result is a lattice girder which is particularly simple to manufacture and assemble and which, in the case of a detachable connection, facilitates disassembly and transport.
