Definitions

  • the present invention has as its subject a tubular tower and a relative construction procedure.
  • it refers preferably to an entirely bolted monotubular tower for use in wind power stations as a support for wind turbines with revolving blades. For this reason this type of tower is commonly known as a "wind tower”.
  • Blades and towers are known having fairly limited dimensions and therefore made in monolithic taper sections longitudinally welded directly in the factory and subsequently assembled on site, joined by lapped joints or flanges welded to the ends.
  • Wind towers are known in which the various taper sections are fixed to each other by means of welded flanges or, in the case of larger sizes, by the use of drilled plates joining the taper sections by means of bolts. Moreover, in all the most current realisations, the connection to the foundations is made by wholly or partially welded elements. These however are structural solutions whose execution is both demanding to perform and imposes limitations.
  • Wind towers running at full speed are subject to oscillations and vibrations of very significant size and frequency and are therefore extremely sensitive to fatigue, which becomes particularly critical especially in the area of welds, where the possible presence of cracks dangerously amplifies the effects.
  • An object of the present invention is to eliminate the above disadvantages, and to make available a wind tower and a procedure for constructing it which provide the tower with better functionality and resistance to stresses, as well as making it easier to assemble.
  • FIG. 1 illustrates the tower in a front view, without the turbine on the top
  • - figure 2 illustrates a drilled flat sheet before folding
  • - figures 3a, 3b and 3c illustrate the folded sheet, respectively in a front view, on plan and in a perspective view
  • FIG. 4a, 4b and 4c illustrate a taper section forming part of the tower, respectively in a front view, on plan and in a perspective view;
  • FIG. 5a, 5b and 5c illustrate the "joining elements", respectively in a front view, on plan and in a side view;
  • FIG. 6a and 6b illustrate a top "joining element", respectively in a front view and in a sectioned side view;
  • - figures 7a and 7b illustrate intermediate "joining elements", respectively in a front view and in a sectioned side view
  • - figures 8a and 8b illustrate a base "joining element”, respectively in a side view and in a front view
  • no. 1 comprehensively indicates a tower, made by assembling a plurality of overlapping taper sections 2.
  • Each taper section which is conical with a hexadecagonal cross-section (i.e. with 16 sides) is made by assembling four segments 3 (illustrated in figures 3a, 3b and 3c) with their lateral flaps 4 folded towards the inside of the tower.
  • the diameter of the taper section can even be greater than 4 metres, and numerous assembly operations carried out on site can be performed by working from inside the taper section. Assembly of the four segments (illustrated in figures 4a, 4b and 4c) is performed by longitudinal bolting of the flaps 4 , folded so as to form a single body. For this bolting operation, holes 5 are used, into which appropriate bolts are fitted.
  • Some operations are carried out on site, i.e. in the place where the tower is being erected, other operations are carried out in the factory, i.e. in the place where the individual constituent elements are prepared before being transported to the site.
  • the constituent segments 3 are equipped with joining elements 6 pre- fitted (bolted) in the factory to the ends of the segments on the inner side of the sheet, in such a way that the corresponding joining elements can be connected by means of high-strength tie-rods 7 secured by nuts 8, thus making the joint between the taper sections as illustrated in figures
  • the tubular tower comprises: - a plurality of superimposed taper sections 2 connected together;
  • said tower is preferably (but not exclusively) configured to support a wind power station.
  • a taper section 2 A is connected to a taper section 2B adjacent thereto (when the taper sections 2A and 2B are superimposed to form the tower) by means of couples of joining elements 6 preliminarily fixed to the taper sections and tie-rods 7 successively (when the taper sections 2A and 2B are already superimposed) inserted therein.
  • At least one of the taper sections 2 is provided with at least a fist and a second joining element 6 fixed to opposite ends of the taper section 2, to connect said taper section 2 to correspondent taper sections 2 arranged at opposite sides of said t least one taper section 2, when the taper sections 2 are superimposed to form the tower.
  • the joining elements intended for attaching a top plate 10 are also pre- fitted to the inside.
  • the joining elements are preferably pre-fitted to the outer surface of the sheet, in order to optimise the coupling to the anchor bolts 11 emerging from the foundations, as illustrated in figures 8a and 8b.
  • the joining elements 6 and the relative tie-rods 7 constitute joining devices.
  • the procedure normally provides for the following stages: a) in the factory:
  • the joining elements could be internal or external, or both internal and external, according to the type of stresses which the tower is destined to bear. In the preferred embodiment illustrated, however, they are internal to the tower, except in the case of the joining elements securing the base taper section to the anchor bolts.
  • Figures 9-13 illustrate schematically a possible procedure for assembling the tower on site which includes:
  • figure 15 shows holes 14 and 15 respectively for fixing the first brackets and the second brackets;
  • a guide cradle 21 which can be adjustable for width by means of movable lateral stands 23 comprising square section tubular elements 24 and round section tubular elements 25;
  • Another construction process provides for setting up two cradles adjacent to each other along a common longitudinal edge of the structures contained in them, in such a way as to allow one structure to be rotated over the other around this longitudinal edge.

Abstract

L'invention est relative à une tour tubulaire, du type utilisé pour des stations d'énergie éolienne, caractérisée en ce qu'elle comprend une pluralité de sections coniques superposées (2) qui sont connectées les unes aux autres en utilisant des éléments de jonction spéciaux (6) qui sont boulonnés aux extrémités des sections coniques, ainsi que des tirants d'assemblage (7) qui sont insérés de façon longitudinale dans lesdits éléments de jonction (6) et fixés à l'aide d'écrous (8). L'invention revendique également une procédure innovante pour construire la tour. Contrairement à la technique antérieure, les tirants d'assemblage, qui sont agencés de façon longitudinale et contraints uniquement en traction, sont utilisés pour connecter les sections coniques. En outre, une partie de la tour est pré-assemblée dans l'usine, pour former une pluralité de composants qui sont ensuite assemblés sur le site.
