Definitions

  • the invention relates to a mast-like, spatial framework structure according to the preamble of claim 1.
  • a known truss structure of the type mentioned (US-A 30 11 586) two flat trusses are arranged opposite one another.
  • the third side is formed by struts which carry bushes in the area of the truss nodes, with which they are pivotally mounted on the adjacent longitudinal members of the two flat trusses.
  • the struts are in turn connected at one end to sleeves pivotally mounted on the adjacent longitudinal beam of one of the flat trusses.
  • the opposite ends carry releasable connecting means with which they can be connected to the corresponding longitudinal member of the other truss.
  • This truss structure can be folded like a leporello to a width corresponding to the width of the flat trusses forming one side of the structure. During assembly, they are brought to a square cross-section by inserting rigid end plates.
  • Mast-like, spatial framework structures with a square cross-section appear expedient for the creation of larger spatial structures in earth orbits.
  • the object of the invention is to develop a truss structure that largely meets the requirements of a small transport volume, an extremely low weight and easy assembly in the orbit.
  • the truss structure designed according to the invention can be transported flat folded into the room and can be brought into its final shape by actuating the tensioning rope, in which it has a high stability.
  • a truss structure is shown schematically in the folded state.
  • the spatial truss structure has four strut trusses 2, 4 and 6, 8 of the same height H, the compartments of which are preferably designed as isosceles triangles.
  • the strut trusses each have parallel longitudinal beams 10, 12, between which the struts 12 are arranged at an angle of 60 °.
  • the connection nodes are not shown in detail in FIG. 1.
  • the strut trusses are each connected to one another on their longitudinal beams 10 and 12 via articulated connections 16, 18 which are arranged in the region of the nodes.
  • the longitudinal beams 10, 12 and the struts 14 are wound CFRP tubes and the nodes are also wound as tubular bodies using CFRP technology.
  • the pipe elements are glued to the nodes.
  • Such a structure has a high strength with an extremely low weight.
  • the tubular structure can be seen from FIGS. 2 to 4.
  • two strut trusses 2, 6 and 4, 8 are connected to each other via the articulated connections 16 and 18 so that two adjacent strut trusses 2 and 6 or 4 and 8 are stretched and these two are arranged stretched Couples lie directly on top of each other.
  • tension cables 20 are arranged, the fixed length of which corresponds to the diagonals of the truss structure in the unfolded state. They are held on tabs on the hinge pin, which will be described in more detail below.
  • U-shaped tabs 24, 26 are in each case on the hinge pins of the hinge connections 16 which are on the outside in the folded state pivoted.
  • lugs 24 on one side is mounted a guide roller 28, while the tabs 26 on the opposite side two independent Uml 'enkrollen 30, are rotatably mounted 32 which, as shown in the drawing, preferably independently on parallel axes from each other, are arranged, but can also be rotatably mounted on a common axle pin.
  • the tensioning cable 22 is guided between the individual nodes along one of the supports 10 of the strut trusses 6 and 8 that are located outside in the folded position.
  • the tensioning cable is guided across the roles of the tabs 26 across the roll of the opposite tab 24 and from there back to the structure. In this way, a two-strand bottle is formed. In this way, the tensioning rope extends across the structure in the area of preferably all nodes.
  • the flat-folded structure is unfolded, as can be seen from the sequence of the illustrations in FIGS. 2, 3 and 4.
  • the deployment movement is complete when the fixed cables are stretched.
  • the quadrangular, preferably square, cross-sectional shape according to FIG. 4 is reached.
  • the tensioning rope is then fixed by locking the drum or using a locking mechanism.
  • the two-strand bottle guide of the tensioning rope achieves a high tensioning force in the diagonal of the truss structure with low tensile force on the rope. Since this tension is absorbed by two strands of rope, the rope as a whole can be made relatively thin and therefore of low mass. With a truss height H of 2 m, the tensioning rope can have a diameter of 2 mm, for example.
  • the truss structures formed in the manner described preferably form individual sections from which longer truss structures can be created by stringing them together, from which in turn frame-shaped structures can be constructed.
  • the individual strut trusses can, as shown in dashed lines in Fig. 1, be closed at their ends by vertical supports 3, so that individual shots are formed in this way, a plurality of which can be put together.
  • free pipe ends can also be provided at one end, which can be inserted during assembly into appropriately designed node connections of a structural section to be connected.
  • a plurality of collapsed shots can also be connected to one another in a pivotable manner, the connection advantageously being made like a leporello with more than two structures.
  • the connections can be designed such that the individual structures connected in this way are automatically unfolded and, if necessary, are still connected to one another in the folded state when the stretched position is reached.
  • the longitudinal connection can then be made, for example, by means of longitudinal tensioning cables which are guided within the longitudinal beams.
  • the entire structure of several structure sections can then be unfolded by means of the tensioning cable, which can also be guided over several structure sections. Then the longitudinal tension cables in the longitudinal beams can be brought to the final tension and locked.
  • FIGS. 5 and 6a and 6b show a preferred embodiment of an articulated connection, specifically one of the articulated connections 16 between the longitudinal members 10 which are on the outside in the folded state.
  • the articulated connection 16 lies in the region of two opposite node elements 36, 38. These node elements have continuous Socket sections 40, 42 in the area of the side members into which the tubular elements of the side members are inserted and glued. At an angle of 30 ° to the vertical then connection sleeves 44, 46 are provided at each node, which are wound in one piece with the pipe sleeves 40.
  • the two node elements 36 and 38 are further provided with hinge plates 48, 50 in the region of their ends.
  • These hinge straps have hinge bushings 52 which are held in contact with winding strands on the outer circumference of the pipe sleeve 40.
  • the hinge bushings can also be formed in shaped pieces which are wrapped by the winding strand.
  • the axis of the joint bushings lies at an angle a, which corresponds to half the swivel angle of the joint, to the perpendicular through the plane E of the nodes.
  • the winding strands are wound in one work step with the truss knot.
  • Two such link plates 48, 50 are provided at each end of the knot.
  • the hinge pin extends over the entire length.
  • Further bearing bushes can be provided in the central region of the knot, as indicated by the winding strand 56 in FIG. 6b.
  • the hinge axis lies at a distance D from the axis of the sleeve sections 40, 42 and thus the tubular longitudinal beam 10.
  • the U-shaped hinge bracket 24 or 26 is pivotably mounted on a continuous hinge pin 60. 5 and 6a and 6b, this is the tab 26 with the two profiled pulleys 30 and 32, which are spaced apart from one another on parallel axle bolts 31. If a central articulated connection is also provided, the tab 26 can overlap this articulated connection in a bridge-like manner . Spacers 58 can also be arranged on the hinge pin 60 for axially fixing the tab 26. The tensioning cable is guided laterally through the legs of the tabs.
  • the packing height of the folded structure is determined by the thickness of the tabs 26 between the nodes.
  • the outer contour of the tab of the outer contour of the knots can be adapted, for example, by forming a concave constriction 54 on both sides in the longitudinal direction in the region in which it lies between the knots when the structure is folded. The two legs can lie directly against each other at the deep point of the constriction. The distance D is determined accordingly.
  • the tab 24 is mounted on the articulated connection on the opposite side of the structure.
  • the tab is only provided with a deflection roller.
  • the fixed cables can be provided with thimbles or the like at their ends, and a U-shaped fastening tab can then be provided, into which the thimble is inserted and fixed by a plug pin.
  • These fastening tabs can be pivoted in the same way on the articulated connections 18, which are otherwise formed in the same way on the nodes as the articulated connections 16.
  • FIG. 7 shows two adjacent strut trusses that lie next to each other in the folded position, that is to say trusses 2 and 6 or 4 and 8.
  • the two other trusses are not shown in order to achieve greater clarity. They are articulated in the nodes 36 and 38 of the two strut trusses 2 and 6.
  • the fixed tensioning cables 20 are only hinted at. In the unfolded position, as shown in FIG. 4, they are stretched taut between the articulated connections between the strut trusses 2 and 4 or 6 and 8.
  • deployable sun wings can be mounted so that the spatial transport volume is not increased.
  • preassembled units can create large areas of sun wing fields within a closed frame structure formed by truss structures of the described space.
  • the arrangement of the solar wings can and should thereby he f ol gene that occurs due to one-sided loading shear forces are transmitted via the fixed rope diagonals on the other structure.
