Definitions

  • the invention relates to a structure for supporting a directional effect device which is placed substantially at the top of a mast.
  • the invention relates more particularly but not exclusively to structures formed to support radioelectric antennas with directional effects.
  • This twist induces the depointing of the antenna and the loss of all or part of the information transmitted by its intermediary.
  • This structure conventionally comprises a plurality of beams which, on the one hand, extend substantially radially to the longitudinal axis of the mast, and this, according to a generally regular angular distribution and, on the other hand, are each, by one of their ends, associated with said mast by a connection means of the built-in type and, at their opposite end, connected to a fixed point with respect to the foot of the mast in particular via a stretched cable said guy cable.
  • this type of structure does indeed make it possible to hinder the torsion of the mast, on the other hand, it does not hamper its bending, in particular in its extreme part situated above this structure.
  • the subject of the invention is a structure of the aforementioned type, in particular characterized in that, in addition to the beams orthogonal to the mast, it includes a plurality of so-called bracing elements which each extend above a determined plane. by the aforementioned beams, when the mast is considered in a vertical position, each of these elements being interposed via removable connection means between, on the one hand, one of the beams towards its end connected to the fixed point and, on the other hand, the mast substantially below the area of said mast to the right of which the directive device is carried.
  • a structure 1 intended to support at least indirectly at least one device 2 with directional effect substantially at the top of a mast 3 approximately vertical and cylindrical of revolution.
  • the structure 1 conventionally comprises a plurality of beams 4 which, on the one hand, extend substantially radially to the longitudinal axis 5 of the mast 3, and this, according to a generally regular angular distribution and, on the other hand, are each, by one of their ends 6, associated with said mast by a means 7 for connecting the built-in type and, at their opposite end 8, connected to a point 9 fixed with respect to the foot of the mast, in particular via a tensioned cable 10 said guy cable.
  • the structure 1 in addition to the beams 4 orthogonal to the mast 3, the structure 1 comprises a plurality of elements 12 called bracing elements which each extend above a plane P1 determined by the above-mentioned beams 4, when we consider the mast 3 in vertical position, each of these elements 12 being interposed via means 13, 14 of removable connection between, on the one hand, one of the beams towards its end connected to the fixed point 9 and, on the other hand, the mast 3 substantially below the zone 15 of the said mast 3 to the right of which the directional device 2 is carried.
  • bracing elements which each extend above a plane P1 determined by the above-mentioned beams 4, when we consider the mast 3 in vertical position, each of these elements 12 being interposed via means 13, 14 of removable connection between, on the one hand, one of the beams towards its end connected to the fixed point 9 and, on the other hand, the mast 3 substantially below the zone 15 of the said mast 3 to the right of which the directional device 2 is carried.
  • each of their ends 7 intended to cooperate with the said mast 3 carries a part 16 bearing on the cylindrical wall 17 of the mast 3, and this, according to a cylindrical sector C extending over a determined angular fraction, and, on the other hand, these support pieces 6 comprise means 18, 19 for assembly together and for energetic application on the cylindrical wall 17 of the mast.
  • each support piece 16 extends over a fraction of the perimeter of the mast in relation to the number of beams 4 radially arranged around said mast.
  • each support piece 16 consists of a fraction of cylindrical crown with an internal diameter equivalent to that of the section of the mast 3 with which it must cooperate and, on the other hand, each of these fractions 16 of the crown carries at the right of each of these ends 20, 21 a lug 18 which, extending in a plane P2 radial to the longitudinal axis 15 of the crown and passing through this axis, has bearing surfaces 22, 23 and / or cutouts 24 for the support and the passage of at least one assembly member 19 intended to cooperate with a lug 18 opposite screw, that is to say located on another fraction of the crown, the various aforementioned components constituting the means 18, 19 for assembling the support pieces together and for energetic application against the wall of the mast.
  • the assembly members 11 consist of eye bolts, each articulated by a pin 22 integral with one of the lugs 18 of each fraction 16 of the crown and, each of these bolts 19, carries a nut 25 intended to cooperate with the bearing surface 23 of an opposing tab in which a cutout 24 is arranged allowing the engagement of the assembly member 19.
  • the means 13 for connection between the lower end 26 of a bracing element 12 and the end 8 of each radial beam to the mast and comprises a part 27 integral with the lower end 28 of the element 12 of bracing, in particular via a connection of the built-in type, and this part 27 on the one hand cooperates with the associated end of the radial beam 4 by means 29 of articulation around an axis 30 substantially horizontal and perpendicular to the longitudinal axis 31 of said beam and, on the other hand, has at least one bearing surface 32 of at least indirect anchoring for the end 33 of a guy cable 10.
  • the means of connection 14 to the mast of the upper end 34 of each bracing element 12 comprises a bore 35 which, reserved in the mast 3 according to the inclination and the orientation of the element not only with respect to the longitudinal axis 5 of the mast but also with respect to the other bracing elements 12 is of at least sufficient cross-section to cooperate by interlocking with the upper end 34 of an element and, on the other part, comprises at least one means 36 of immobilization controlled in the nested position of the upper end of the element in the bore in question of the mast.
  • the means 36 of controlled immobilization associated with each means 14 for connection to the mast of the upper end of each bracing element consists of a pin 36 which finds housing in reserved bores 37, 38, 39 (37, 38) in the mast and transversely (39) in the upper end of each bracing element 12.
  • each pin 36 carries a means 40 for locking in translation in the aligned bores 37, 38, 39 of the mast and of the corresponding upper end 34 of a bracing element.
  • the heavy body is constituted by an extreme free section of the pin, which is bent so as to be offset relative to the longitudinal axis of the pin and thus constitute at least indirectly the lever 46 mentioned.
  • the bores 37, 38, 39 provided in the mast and in each upper end of a bracing element for receiving a pin are, from their entrance, tilted down.
