Description

L'invention se rapporte à une structure destinée à supporter un appareil à effets directifs qui est placé sensiblement au sommet d'un mât.The invention relates to a structure for supporting a directional effect device which is placed substantially at the top of a mast.

L'invention intéresse plus particulièrement mais non exclusivement des structures constituées pour supporter des antennes radioélectriques à effets directifs.The invention relates more particularly but not exclusively to structures formed to support radioelectric antennas with directional effects.

L'action du vent sur les antennes du type précité et particulièrement sur les antennes comprenant un réflecteur du type parabolique, provoque généralement la torsion élastique du mât.The action of the wind on the antennas of the aforementioned type and particularly on the antennas comprising a reflector of the parabolic type, generally causes the elastic torsion of the mast.

Cette torsion induit le dépointage de l'antenne et la perte de tout ou partie des informations transmises par son intérmédiaire.This twist induces the depointing of the antenna and the loss of all or part of the information transmitted by its intermediary.

Pour obvier à cette torsion du mât, il est connu de doter son extrémité supérieure d'une structure entravant précisément la torsion de la dite extrémité supérieure autour de l'axe longitudinal du mât.To obviate this torsion of the mast, it is known to provide its upper end with a structure precisely hindering the torsion of said upper end around the longitudinal axis of the mast.

Cette structure comprend classiquement une pluralité de poutres qui, d'une part, s'étendent sensiblement radialement à l'axe longitudinal du mât, et ce, selon une répartition angulaire globalement régulière et, d'autre part, sont chacune, par l'une de leurs extrémités, associée au dit mât par un moyen de liaison du type à encastrement et, à leur extrémité opposée, reliée à un point fixe par rapport au pied du mât notamment via un cable tendu dit cable de haubannage.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.

Si ce type de structure permet effectivement d'entraver la torsion du mât, en revanche, il n'entrave pas sa flexion notamment en sa partie extrême située au dessus de cette structure.If 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.

A cet effet, l'invention a pour objet une structure du type précité notamment caractérisée en ce que, outre les poutres orthogonales au mât, elle comprend une pluralité d'éléments dits de contreventement qui s'étendent chacun au dessus d'un plan déterminé par les poutres précitées, lorsqu'on considère le mât en position verticale, chacun de ces éléments étant interposé via des moyens de liaison démontable entre, d'une part, l'une des poutres vers son extrémité reliée au point fixe et, d'autre part, le mât sensiblement en dessous de la zone du dit mât au droit de laquelle l'appareil directif se trouve porté.To this end, 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.

L'invention sera bien comprise à la lecture de la description ci-aprés faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement:

  • - figure 1: une vue en perspective de l'objet de l'invention,
  • - figure 2: une vue partielle et en coupe de l'objet de l'invention dans un plan longitudinal,
  • - figures 3 et 4: des détails de réalisation de l'invention à différentes échelles.
The invention will be clearly understood on reading the description below made by way of nonlimiting example with regard to the attached drawing which schematically represents:
  • - Figure 1: a perspective view of the subject of the invention,
  • FIG. 2: a partial view in section of the object of the invention in a longitudinal plane,
  • - Figures 3 and 4: details of embodiment of the invention on different scales.

En se reportant au dessin, on voit une structure 1 destinée à supporter au moins indirectement au moins un appareil 2 à effet directif sensiblement au sommet d'un mât 3 approximativement vertical et cylindrique de révolution.Referring to the drawing, we see 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.

Tel que cela apparaît au dessin, la structure 1 comprend classiquement une pluralité de poutres 4 qui, d'une part, s'étendent sensiblement radialement à l'axe longitudinal 5 du mât 3, et ce, selon une répartition angulaire globalement régulière et, d'autre part, sont chacune, par l'une de leurs extrémités 6, associée au dit mât par un moyen 7 de liaison du type à encastrement et, à leur extrémité 8 opposée, reliée à un point 9 fixe par rapport au pied du mât notamment via un cable 10 tendu dit cable de haubannage.As shown in the drawing, 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.

Selon l'invention, outre les poutres 4 orthogonales au mât 3, la structure 1 comprend une pluralité d'éléments 12 dit de contreventement qui s'étendent chacun au dessus d'un plan P1 déterminé par les poutres 4 précitées, lorsqu'on considère le mât 3 en position verticale, chacun de ces éléments 12 étant interposé via des moyens 13, 14 de liaison démontable entre, d'une part, l'une des poutres vers son extrémité reliée au point fixe 9 et, d'autre part, le mât 3 sensiblement en dessous de la zone 15 du dit mât 3 au droit de laquelle l'appareil directif 2 se trouve porté.According to the invention, 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.

L'homme de l'art est à même de déterminer les dimensions des poutres et éléments de contreventement pour qu'ils assurent la rigidité recherchée et n'entravent pas l'orientation de l'appareil à effet directif autour de l'axe longitudinal du mât.Those skilled in the art are able to determine the dimensions of the beams and bracing elements so that they provide the desired rigidity and do not hinder the orientation of the directional effect device around the longitudinal axis of the mast.

Pour constituer le moyen 7 de liaison des poutres 4 avec le mât 3, d'une part, chacune de leur extrémité 7 destinée à coopérer avec le dit mât 3 porte une pièce 16 d'appui sur la paroi cylindrique 17 du mât 3, et ce, selon un secteur cylindrique C s'étendant sur une fraction angulaire déterminée, et, d'autre part, ces pièces d'appui 6 comportent des moyens 18, 19 d'assemblage entre elles et d'application énergique sur la paroi cylindrique 17 du mât.To constitute the means 7 for connecting the beams 4 with the mast 3, on the one hand, 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.

Par exemple, chaque pièce d'appui 16 s'étend sur une fraction du périmètre du mât en rapport avec le nombre de poutres 4 radialement disposées autour du dit mât.For example, 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.

Dans une forme préférée de réalisation, d'une part, chaque pièce d'appui 16 consiste en une fraction de couronne cylindrique de diamètre intérieur équivalent à celui du tronçon du mât 3 avec lequel elle doit coopèrer et, d'autre part, chacune de ces fractions 16 de couronne porte au droit de chacune de ces extrémités 20, 21 une patte 18 qui, s'étendant dans un plan P2 radial à l'axe longitudinal 15 de la couronne et passant par cet axe, présente des portées 22, 23 et/ou des découpes 24 pour l'appui et le passage d'au moins un organe d'assemblage 19 destiné à coopérer avec une patte 18 en vis à vis, c'est à dire située sur une autre fraction de couronne, les divers composants précités constituant les moyens 18, 19 d'assemblage des pièces d'appui entre elles et d'application énergique contre la paroi du mât.In a preferred embodiment, on the one hand, 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.

Par exemple, les organes d'assemblage 11 consistent en des boulons à oeil, chacun articulé par un axe 22 solidaire de l'une des pattes 18 de chaque fraction 16 de couronne et, chacun de ces boulons 19, porte un écrou 25 destiné à coopérer avec la portée 23 d'une patte antagoniste dans laquelle est aménagée une découpe 24 permettant l'engagement de l'organe d'assemblage 19.For example, 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.

Suivant l'invention, le moyen 13 de liaison entre l'extrémité inférieure 26 d'un élément 12 de contreventement et l'extrémité 8 de chaque poutre radiale au mât et comprend une pièce 27 solidaire de l'extrémité inférieure 28 de l'élément 12 de contreventement, notamment via une liaison du type à encastrement, et cette pièce 27 d'une part coopère avec l'extrémité associée de la poutre radiale 4 par un moyen 29 d'articulation autour d'un axe 30 sensiblement horizontal et perpendiculaire à l'axe longitudinal 31 de la dite poutre et, d'autre part, présente au moins une portée 32 d'ancrage au moins indirect pour l'extrémité 33 d'un cable de haubannage 10.According to the invention, 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.

Suivant l'invention, le moyen de liaison 14 au mât de l'extrémité supérieure 34 de chaque élément de contreventement 12, d'une part, comprend un alésage 35 qui, réservé dans le mât 3 selon l'inclinaison et l'orientation de l'élément non seulement par rapport à l'axe longitudinal 5 du mât mais également par rapport aux autres éléments 12 de contreventement est de section au moins suffisante pour coopérer par emboitement avec l'extrémité supérieure 34 d'un élément et, d'autre part, comporte au moins un moyen 36 d'immobilisation contrôlée en position emboitée de l'extrémité supérieure de l'élément dans l'alésage considéré du mât.According to the invention, the means of connection 14 to the mast of the upper end 34 of each bracing element 12, on the one hand, 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.

Conformément à l'invention, le moyen 36 d'immobilisation contrôlée associée à chaque moyen 14 de liaison au mât de l'extrémité supérieure de chaque élément de contreventement consiste en une goupille 36 qui trouve logement dans des alésages alignés 37, 38, 39 réservés (37, 38) dans le mât et transversalement (39) dans l'extrémité supérieure de chaque élément 12 de contreventement.According to the invention, 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.

Selon l'invention, chaque goupille 36 porte un moyen 40 de verrouillage en translation dans les alésages 37, 38, 39 alignés du mât et de l'extrémité supérieure 34 correspondante d'un élément de contreventement.According to the invention, 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.

Selon l'invention:

  • - d'une part, le moyen 40 de verrouillage est du type à pêne oscillant c'est à dire que chaque goupille comprend une butée axiale 41 qui s'étend radialement et localement sur son flanc 42 et qu'au droit de chaque groupe d'alésages alignés du mât et destinés à recevoir une goupille, le mât porte au moins une butée 43 derrière laquelle la butée 41 de la goupille 36 peut être engagée par un mouvement de rotation d'amplitude prédéterminée autour de son axe 44, et ce, aprés engagement de la dite goupille en posistion d'immobilisation de l'extrémité supérieure d'un élément dans un alésage du mât et,
  • - d'autre part, la goupille 36 porte au moins un corps pesant 45 par le biais d'un levier 46 orienté pour, par gravité, induire la rotation de la goupille en position de verrouillage et/ou assurer son maintien en cette position.
According to the invention:

  • - On the other hand, the pin 36 carries at least one body weighing 45 by means of a lever 46 oriented to, by gravity, induce the rotation of the pin in the locked position and / or ensure its maintenance in this position.

Par exemple, le corps pesant est constitué par un tronçon extrême libre de la goupille, lequel est coudé de manière à être déporté par rapport à l'axe longitudinal de la goupille et constituer ainsi au moins indirectement le levier 46 évoqué.For example, 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.

Dans un mode préférentiel de réalisation, lorsque le mât est érigé et que la structure est installée, les alésages 37, 38, 39 prévus dans le mât et dans chaque extrémité supérieure d'un élément de contreventement pour recevoir une goupille sont, à partir de leur entrée, inclinés vers le bas.In a preferred embodiment, when the mast is erected and the structure is installed, 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.

Conformément à l'invention:
