Definitions

  • the present invention relates to a tower, in particular for supporting telecommunication appliances, for example antennas.
  • the towers for supporting telecommunication appliances are substantially divided into two categories, according to height: trestles, suitable for reaching high heights, for example more than ten metres, and the simpler towers of tubular shape for smaller height. The latter serve for example for supporting the antennas of shelters for telecommunication appliances.
  • towers consist of tubular elements of cylindrical or polygonal shape with a few metres length. Despite their large thickness, more tubular elements must be piled up on top of each to other to obtain sufficient heights.
  • each tubular element is provided with connecting flanges at the ends thereof that must necessarily be made separately and then welded to the tubular body.
  • each tubular element of the tower has a considerable weight, which requires the use of a crane for handling thereof. Since these towers are mainly intended for movable installations, the problem of the handiness and transportability thereof is much felt.
  • the object of the present invention is to propose a tower of the second type which should allow obviating the disadvantages mentioned above with reference to the towers used so far.
  • the object of the present invention is to propose a tower which should allow reaching much higher heights and which should be at the same time much lighter, much easier to made and assemble and much handier and more convenient to carry and store. [0007] Such objects are achieved with a tower according to the following claims.

Abstract

La présente invention concerne une tour, destinée en particulier mais pas exclusivement au support d'appareils de télécommunication, qui comprend une pluralité de barres disposées les unes à côté des autres le long des côtés respectifs afin de former une structure parallélépipède creuse à section polygonale, chaque barre comportant un corps de barre définissant au moins un côté de ladite structure parallélépipède. Les barres sont reliées les unes aux autres au moyen d'appendices de raccord longitudinaux, qui sont par exemple boulonnés les uns aux autres. De plus, il est possible de superposer de nombreuses barres en hauteur. Dans tous les cas de figure, la tour ainsi obtenue est dépourvue de soudure, facile à entreposer, transporter et monter.
