Definitions

  • the present invention relates to a trellis structure advantageously made of reinforced resin which can be used in particular as a mast for supporting high power antennas at significant heights, of several tens of meters.
  • reinforced resin antenna masts are known compared to metal masts.
  • the reinforced resin is non-magnetic and insulating and therefore does not create any electromagnetic disturbance. Its low density facilitates transport and handling. Its corrosion resistance allows very long lifetimes.
  • the invention relates to a trellis structure, usable as a mast and which, made of reinforced resin, has a mechanical resistance comparable to that of metallic structures.
  • US-A-3 100 555 discloses a tubular lattice structure, constituted by a plurality of continuous cylindrical uprights, assembled by braces constituted by members enveloping these uprights and fixed to them, provided with sockets receiving the ends of bracing struts.
  • the invention aims to provide a structure of the type indicated above, but the assembly of which can be prepared in the factory and carried out in a simple manner at the place of use.
  • the structure is divided into successive adjacent sections and that, in each section, the entire bracing is a rigid and independent module, like those described in DE-U-1 626 712, but comprising a plurality spacers engaged in sockets integral with the sleeves in which the uprights are threaded and which, on each side, constitute the ends of this module.
  • bracing panels of the same section of the structure are assembled together in advance via said sleeves to form a module, the continuous series of adjacent modules being finally traversed by the frames and assembled therewith appropriately.
  • each panel is constituted by four spacers, in the form of cylindrical bars, assembled in the same plane by a crosspiece comprising for this purpose four cross sockets.
  • each sleeve open inside of it, their axes compete with each other and with the axis of the sleeve.
  • this sleeve is limited, towards the neighboring module, by a plane perpendicular to its axis passing through the point of intersection of these axes.
  • the diameter of the sleeve being larger than that of the sockets, it is possible for mounting the modules on a template to engage each of the spacers in its socket by passing through the sleeve and then advancing it to the crosspiece, this which avoids the difficulty of assembling a panel by engaging both the ends of the spacers in the sleeves for housing the sleeves and the spider and then gradually reducing the size of the geometric figure thus produced.
  • the structure (beam or mast) may be of any length in one piece or formed of sections assembled by end-to-end connection of the sections of members, this assembly and the modes of use of the structures are not part of the invention.
  • this mast is held in its erected position by a set of shrouds, not shown.
  • the mast 1 is formed, in the example shown, of three identical structures A, B, C fixed end to end.
  • Each structure can have three parallel members 2 arranged ( Figure 3) along the edges of a regular prism of triangular section.
  • the members 2 are connected two by two by cross-shaped bracing panels 3. As shown in FIG. 2, this panel comprises four identical spacers 4 fixed by one end in the sockets 9 of a spider 5. The spacers 4 are engaged and fixed by their other end in the sockets 6 formed projecting from the sleeves 7 , threaded and fixed on the uprights 2.
  • the sockets 6 are inclined at 45 ° relative to the axis of the sleeve 7 to correspond to the angles of the branches of the spider 5.
  • each corner sleeve element 7 then comprises two sockets 6 situated in planes at 60 ° around the axis of the member.
  • the sockets 6 integral with the same sleeve 7 open inside thereof, which allows to engage each spacer 4 from the inside of the sleeve 7, in its socket 6 until bringing it into the corresponding socket 9 of the spider 5.
  • each point 0 becomes a point node of articulation of the lattice structure.
  • the set of three panels of the same floor and the associated sleeves constitutes a bracing module, composed in this case of six sleeves 7, three cross-pieces 5 and twelve spacers 4.
  • the bracing modules are joined, the sleeves 7 belonging to successive modules having their end faces 8 in contact. After which the members 2 are engaged in the sleeves 7 of the modules and fixed therein in an appropriate manner.
  • Membranes, spacers and sleeves may be of any material provided that they are suitable for assembly by gluing, welding, keying, etc.
  • all of these elements - frames, spacers, cross-pieces and sleeves - are made of fiber-reinforced resin, which allows for resistant bonding.
  • the members and the spacers are tubes which can be obtained by "pultrusion", that is to say by extrusion combined with a traction exerted on the end of the tube during manufacture.
  • they can be filled with a cellular material 10 forming an electrical insulator such as a polyurethane.
  • the cross-pieces 5 and the sleeves 7 can be made of non-rigid thermoplastic material, loaded with glass fibers and injection molded. In this way, each of these elements can play in the structure the role of a joint within the meaning of the theory of articulated trusses; the embedding moments can be considered negligible and the knots being punctual, the spacers and the free portions of the members are stressed in tension or in compression.
  • the sections once assembled in the factory are dismantled for transport, which therefore poses no problems.
  • the invention applies to support masts, in particular for antennas, to provisional or definitive framework elements and other applications which must combine lightness and great range.
