The invention relates to a connection node (10, 20) for the erection of a three-dimensional framework (100), in particular a geodesic structure, wherein the connection node (10, 20) comprises at least one connection arrangement for connecting to other identical connection nodes (10, 20) by means of a predeterminable number (n) of basic structural elements (3) which engage on the respective connection node (10, 20). Provision is made for the connection node (10, 20) to be designed as a disc (4, 6) which comprises a predeterminable number (n) of keyholes (1n), through each of which passes a connecting means (5), and engages in a receiving element (3A) provided on the basic structural element (3n), with the result that each basic structural element (3n) is held rotatably in the first connection arrangement (5, 3A) formed and can be preadjusted, and thus fastened, at any predeterminable angles. The invention also relates to a three-dimensional framework (100), in particular a geodesic structure, which comprises a plurality of arrangeable basic structural elements (3n) which are fastened between the connection nodes (10, 20) to form the three-dimensional framework.

The present invention relates to a support structure for an aircraft, which support structure comprises one or several bar elements (36) and one or several junction elements (37), wherein at least one bar element (36) comprises a transition region (9) which can be made to engage at least one junction element (37). When the transition region (9) of the bar element (36) engages the junction element (37), of which there is at least one, centric force transmission takes place between the bar element (36) and the junction element (37).

A space trust in which the numbers of chord members in the vertical directions and in the horizontal directions and diagonal members are decreased for simplifying fabricating work and the like is obtained. Chord members 2a, 2b, 3a and 3b in the vertical directions and in the horizontal directions in an upper lattice 2 and in a lower lattice 3, respectively, are formed by arranging long rod members 8 having a length twice as long as the distance between intersection points in a lattice, and by coupling coupling portions 8a at ends of long rod members 8 intersecting with a long rod member 8 to the center of the latter long rod member 8, and the diagonal members 4a and 4b coupling intersection points 5 and 6 of the chord members of both of the lattices 2 and 3 with each other are severally formed by arranging bent rod members 10 shaped in a letter V in a lattice, and by coupling coupling portions 10a at ends of the bent rod members 10 intersecting with a bent rod member 10 to the center the bent rod member 10.

The slots of assemblage points (3) open into mutually parallel cylindrical chambers (6) and the engaging heads of the bars are shaped as thickenings (8) corresponding to the length of the chambers, and adapted to the cross-section of the chambers, and are arranged on flattened ends (1a, 2a) of the supporting bars (1, 2). The simple assembly so obtained makes it possible to construct a stable framework structure. The new set of building elements is useful for constructing temporary structures, for example for fairs and exhibitions.

The joint consists of a hollow prism or cylinder which at its sides normal to one another has openings which are at different levels and permit the passage of elongated structural elements, spigot like sleeves extending from the joint at an angle from at least one side of the joint. The new joint has been designed for use in spatial structures and is specially, but not exclusively, adapted for use in spatial roof construction. This joint permits quick and sure connection of the respective structural parts, the necessary operation being effected-wherever desired-in a workshop, thus permitting semi-finished structural parts to be carried to the respective building site for final assembly.
