Definitions

  • the present invention relates to a method to build space framework constructions with a triangular cross section.
  • Space framework constructions occur among other things as unstayed towers, stayed masts and as components of large power-line polyns.
  • the cross section can be square, but one often strives to make them equilaterally triangular, as the number of components will thereby be reduced, which normally above all lowers the costs of manufacture and erection.
  • space framework construc- tions can very well be made with triangular cross section as for towers, masts, power-line polyns, etc. by using an open girder section with flanges at an angle of-60- to each other and an intermediate-web thickness, which is 1,5 - 4 times thicker than the flange thickness.
  • figure 1 shows the frame girder section in cross section figure 2 a longitudinal joint of a frame girder figure 3 a connection between a frame girder and a diagonal stay and figure 4 a connection between a frame girder and a fastening plate fastened e.g. to a foot-plate.
  • frame girders, 1 are used according to the invention in the three corners of the framework.
  • the frame girders of rolled and galvanized steel consist of two flanges of uniform thickness, 2, the elongation of which crosses the symmetry line through the web, 3, with an angle of 30 , a.
  • the web, 3, is to be 1,5 - 4 times thicker than the flanges, 2. It should as shown be twice as thick as the flanges.
  • the web, 3, is somewhat shorter than the flanges, 2.
  • a space framework according to the invention can be built up of componets made in a workshop and can then be assemblied on site by personnel, who is rather unqualified. Manufacture and erection of a space framework according to the invention is calculated to reduce by 40% as for the time compared with hitherto known space frameworks of pipes.

Abstract

Procédé de fabrication de structures à ossature ajourée, présentant une section triangulaire et conçues surtout pour les tours sans haubanage, des mâts haubanés et comme éléments de grands pylônes pour lignes à haute tension. Comme poutres de l'ossature on utilise un profilé en acier laminé, dont les semelles sont plates et de dimensions égales. La lame intermédiaire que relie les bords des semelles a une épaisseur qui est environ le double de celle des semelles.
