Definitions

  • the invention is an effective node solution to successfully design and construct space structures made up of different sectional elements.
  • the node was developed to be capable of connecting the various sectional members located in three dimensional space together to a single joint.
  • the node had to be designed as strong, stiff, structurally stable yet mechanically simple with minimum eccentricity.
  • the invention is aimed towards spaceframe structures of up to approximately 20m clear span, employing an efficient, fast and clean design, manufacture and assembly of such structures, both for aesthetic and functional purposes.
  • space structures are manufactured from any type of member of any material which is structurally adequate, and amenable to the method of manufacture.
  • the size of the elements (10, 20) varies with the structural/aesthetic requirements of the project in hand.
  • the elements are divided into 2 main groups - the main booms (10) , those parallel to the direction of span, and the diagonal members (20) . Welding is removed from the jointing system, implying the possibility of a cost-effective and if required a relocatable solution.
  • the ends of the elements (10, 20) are cut to size and prepared in a pressing machine or other similar equipment to prepare the adequate jointing surface.
  • the edges are squashed to approximately half the flattened width, or one fourth of the pipe circumference.
  • the ends of the diagonal members (20) are also bent to the required angle depending on the design height of the space frame and then cut or sheared to form the 45 degree rotated end shown in FIG 1 and 3 .
  • Two holes (40) are drilled or punched at the ends of the main booms (10), while one hole is drilled or punched at the ends of the diagonal elements (20) .
  • these holes (40) depends on the size of the bolts (41) which in turn are related to the structural/aesthetic requirements of the project and on practical end distances required by the relative British Standards and Eurocodes.
  • These elements are assembled together at the node as shown in FIG 1-4 .
  • Adequate spacers in the form of plates (30) with four holes (40) of a diameter and spacing similar to that of the rest of the node are placed between the diagonal elements (20) and the main booms (10), as shown in FIG 1-4 , to enable the lines of force of the structural system to meet at one point. Therefore, the depth of these spacers (30) , that is, the distance between the main booms (10) and the diagonals (20) at the node, will vary with the particular structural geometry of the specific project.
  • a finishing plate (50) with four holes (40) of a diameter and spacing similar to that for the rest of the node is then placed over the diagonal members before final fixing with four adequate strength bolts (41) .
  • the size and grade of the bolts is generally a result of strength requirements.
