Definitions

  • the invention relates to a lattice girder, in particular for space trusses, with two belt profile bars which are connected to one another by struts arranged in a zigzag shape.
  • the invention has for its object to eliminate the above shortcomings and to provide a lattice girder whose individual parts can be economically connected to one another while avoiding welding work.
  • Embodiments of the invention are based on the Sub-claims emerge.
  • the strength of the connection of the struts to the belt profile bars is further improved if the central web of the struts carrying the two flanges has a thickness which practically corresponds to the width of the longitudinal slots in the belt profile bars or if, according to yet another embodiment of the invention, the width of the flanges the struts correspond to the width of the chamber in the belt profile bars.
  • the central web of the struts is preferably perforated or otherwise perforated, which advantageously saves weight on the lattice girders.
  • the lattice girder 10 shown in FIG. 1 has two belt profile bars 11 which are connected to one another by struts 13 of the same type.
  • a screw or clamp connection 14 is attached to both ends of each belt profile rod 11.
  • This connection 14 can be connected to node pieces or profile pieces (not shown), by means of which a number of such lattice girders 10 can be combined to form a spatial structure, as is used, for example, in trade fair and exhibition construction.
  • the struts 13 are of the same type, each consist of a profile with an I-shaped cross section and consequently have a central web 15 and two flanges 16.
  • These struts 13 are, for example, extruded profiles, preferably made of aluminum, which have a surface finish.
  • the belt profile bars 11 also preferably consist of extruded aluminum profiles and are also surface-finished. Furthermore, the belt profile bars 11 have, for example, a box-shaped hollow cross section and a longitudinal slot 18 is arranged in the center on one of their narrow sides. Below the longitudinal slot 18, each belt profile rod 11 contains a chamber 19 which extends continuously in the longitudinal direction and which is delimited, for example, inwardly by a transverse web 20. The I-shaped cross section of the webs 13 is adapted to the belt profile rods 11, which is important in connection with the connection of the struts 13 to the belt profile rods 11.
  • the ends of the struts 13 are cut at an oblique angle, for example in accordance with FIG. 2 at an angle of 43 ° to the main axis of the struts 13.
  • the two flanges 16 of the struts 13 are provided on both sides at each end of the struts 13 with slots 21, which are worked out parallel to the front ends of the struts 13 and at a constant distance from them (FIG. 2).
  • the slots 21 extend to the central web or to a depth at which the remaining center piece c is slightly narrower than the width of the longitudinal slot 18.
  • the height h of the slots 21 is only slightly greater than the thickness d of the legs 22 of the Belt profile bars 11, between which the longitudinal slot 18 extends. Its width practically corresponds to the thickness of the central web 15 of the struts 13, the dimension of the central piece c.
  • the distance A between the respective outer edge of the slots 21 and the respective front end of the struts 13 can correspond, for example, to the clear height H of the chamber 19.
  • the struts 13 are inserted to form the zigzag-shaped arrangement according to FIG. 1, one after the other, in the belt profile bars 11, reversed, and, as can be seen in FIG. 4, they lock each other by touching their ends, while the outermost struts 13 of the lattice girder 10 are fixed to the belt profile rods 11 by clamping screws or similar fastening means, not shown.
  • the belt profile bars 11 with a hollow box-shaped cross section can be replaced by bars with a different hollow cross section, for example by bars 11 'with a round hollow cross section (FIG. 5). These also have a longitudinal slot 18 'and a chamber 19' underneath, which is delimited, for example, inwardly by a transverse web 20 which extends in the longitudinal direction of the rod 11 '.
  • the slots 21 on the struts 13 are here to be designed in a correspondingly arcuate or tangential manner, so that the ends of the struts 13 can be inserted in a suitable manner into the longitudinal slots 18 'and chambers 19' of the belt profile bars 11 '.
  • the latter also consist, for example, of an extruded profile, preferably made of aluminum, and are also surface-finished.
  • the overall height of the lattice girders 10 can be changed in a simple manner.
