Abstract

Lattice-type structure, formed by uprights disposed like the parallel edges of a regular prism, and by windbracing panels connecting said uprights in two's via sleeves fitted and fixed on these respective uprights, said sleeves comprising at least one pair of projecting sockets for connecting the upright with two adjacent windbracing panel elements.

Description

La présente invention concerne une structure en treillis avantageusement réalisée en résine armée utilisable notamment comme mât pour supporter des antennes de grande puissance à des hauteurs importantes, de plusieurs dizaines de mètres.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.

On connaît les avantages des mâts d'antennes en résine armée par rapport aux mâts métalliques. La résine armée est amagnétique et isolante et ne crée donc aucune perturbation électromagnétique. Sa faible densité facilite le transport et la manutention. Sa résistance à la corrosion autorise de très longues durées de vie.The advantages of 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.

Mais lorsque le dispositif à supporter, par exemple une antenne, montée au sommet du mât, représente une charge très importante, de l'ordre de plusieurs tonnes, et que le mât doit avoir une hauteur de plusieurs dizaines de mètres, la résistance mécanique des mâts en résine armée classiques, formés d'éléments cylindriques emboîtés bout à bout, est évidémment insuffisante.But when the device to be supported, for example an antenna, mounted at the top of the mast, represents a very large load, of the order of several tonnes, and the mast must have a height of several tens of meters, the mechanical resistance of the conventional reinforced resin masts, formed of cylindrical elements nested end to end, is obviously insufficient.

L'invention vise une structure en treillis, utilisable comme mât et qui, réalisée en résine armée, présente une résistance mécanique comparable à celle des structures métalliques.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.

La structure selon l'invention est caractérisée par le fait qu'elle est formée de membrures, ou montants,avantageusement cylindriques, disposées comme les arêtes parallèles d'un prisme régulier, et de panneaux de contreventement reliant deux à deux lesdites membrures par l'intermédiaire de manchons enfilés et fixés sur les membrures respectives, manchons comportant au moins une paire de douilles en saillie pour la liaison de la membrure avec deux éléments de panneaux adjacents.The structure according to the invention is characterized in that it is formed of members, or uprights, advantageously cylindrical, arranged like the parallel edges of a regular prism, and of bracing panels connecting two by two said said members by the intermediate sleeves threaded and fixed on the respective members, sleeves comprising at least one pair of projecting sockets for the connection of the member with two adjacent panel elements.

De préférence, les panneaux de contreventement d'une même section de la structure (ou du même étage pour un mât) sont d'avance assemblés entre eux par l'intermédiaire des dits manchons pour constituer un module, la suite continue des modules adjacents étant finalement traversée par les membrures et assemblée avec celles-ci de manière appropriée.Preferably, the bracing panels of the same section of the structure (or of the same floor for a mast) are assembled beforehand by means of said sleeves to form a module, the continuous series of adjacent modules being finally crossed by the members and assembled therewith in an appropriate manner.

Dans une forme avantageuse de réalisation, chaque panneau est constitué par quatre entretoises, en forme de barreaux cylindriques, assemblées dans le même plan par un croisillon comportant à cette fin quatre douilles en croix.In an advantageous embodiment, each panel consists of four spacers, in the form of cylindrical bars, assembled in the same plane by a crosspiece comprising for this purpose four cross sockets.

De plus, les douilles de chaque manchon débouchent à l'intérieur de celui-ci, leurs axes concourent entre eux et avec l'axe du manchon. Enfin de préférence, ce manchon est limité, vers le module voisin, par un plan perpendiculaire à son axe passant par le point de concours de ces axes.In addition, the sockets of each sleeve open inside of it, their axes compete with each other and with the axis of the sleeve. Finally, preferably, this sleeve is limited, towards the neighboring module, by a plane perpendicular to its axis passing through the point of intersection of these axes.

Ainsi, le diamètre du manchon étant plus grand que celui des douilles, il est possible pour le montage des modules sur un gabarit d'engager chacune des entretoises dans sa douille en passant par le manchon puis de la faire progresser jusqu'au croisillon, ce qui évite la difficulté de réaliser l'assemblage d'un panneau en engageant à la fois les deux extrémités des entretoises dans les douilles de logement des manchons et du croisillon puis en réduisant progressivement la dimension de la figure géométrique ainsi réalisée.Thus, 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.

En outre lorsque deux manchons appartenant à deux modules voisins sont accolés, tous les axes des entretoises appartenant à ces deux manchons concourent en un même point sur l'axe de la membrure, point constituant un noeud d'articulation de la structure en treillis.In addition, when two sleeves belonging to two neighboring modules are joined, all the axes of the spacers belonging to these two sleeves compete at the same point on the axis of the frame, point constituting an articulation node of the lattice structure.

La structure (poutre ou mât) peut être de longueur quelconque d'une seule pièce ou formée de tronçons assemblés par raccordement bout à bout des tronçons de membrures, cet assemblage ainsi que les modes d'utilisation des structures ne font pas partie de l'invention.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.

L'invention sera bien comprise à la lecture de la description ci-après d'un exemple de réalisation, faite en référence aux dessins annexés.The invention will be clearly understood on reading the description below of an exemplary embodiment, made with reference to the accompanying drawings.

  • La figure 1 montre une structure selon l'invention, en l'espèce un mât d'antenne formé de plusieurs tronçons.Figure 1 shows a structure according to the invention, in this case an antenna mast formed of several sections.
  • La figure 2 représente à plus grande échelle une partie de structure, une seule des faces étant représentée.FIG. 2 shows a part of the structure on a larger scale, only one of the faces being shown.
  • La figure 3 est une coupe transversale suivant le plan III-III de la figure 2.FIG. 3 is a cross section along the plane III-III of FIG. 2.
  • La figure 4 est l'élévation d'un manchon destiné à une structure quadrangulaire.Figure 4 is the elevation of a sleeve for a quadrangular structure.
  • La figure 1 montre un mât 1 destiné à supporter à son sommet un dispositif tel qu'une antenne d'émission ou de réception radioélectrique, non représentée.Figure 1 shows a mast 1 intended to support at its top a device such as a radio transmission or reception antenna, not shown.

De manière connue, ce mât est maintenu dans sa position érigée par un ensemble de haubans, non représentés.In known manner, this mast is held in its erected position by a set of shrouds, not shown.

Le mât 1 est formé, dans l'exemple représenté, de trois structures identiques A, B, C fixées bout à bout. Chaque structure peut comporter trois membrures parallèles 2 disposées (figure 3) suivant les arêtes d'un prisme régulier de section triangulaire.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.

Les membrures 2 sont reliées deux à deux par des panneaux de contreventement 3 en forme de croix. Comme montré sur la figure 2, ce panneau comprend quatre entretoises identiques 4 fixées par une extrémité dans les douilles 9 d'un croisillon 5. Les entretoises 4 sont engagées et fixées par leur autre extrémité dans les douilles 6 formées en saillie sur les manchons 7, enfilés et fixés sur les montants 2. Dans le présent exemple, les douilles 6 sont inclinées à 45° par rapport à l'axe du manchon 7 pour correspondre aux angles des branches du croisillon 5.The members 2 are connected two by two by cross-shaped bracing panels 3. As shown on 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 to the uprights 2. In the present example, the sockets 6 are inclined at 45 ° with respect to the axis of the sleeve 7 to correspond to the angles of the branches of the spider 5.

Sur la figure 3, trois panneaux de contreventement identiques relient en triangle les trois membrures 2; chaque élément manchon d'angle 7 comprend alors deux douilles 6 situées dans des plans à 60° autour de l'axe de la membrure. Comme on peut le voir sur la figure 4, les douilles 6 solidaires d'un même manchon 7 débouchent à l'intérieur de celui-ci, ce qui permet d'engager chaque entretoise 4 par l'intérieur du manchon 7, dans sa douille 6 jusqu'à l'amener dans la douille 9 correspondante du croisillon 5.In FIG. 3, three identical bracing panels connect the three members 2 in a triangle; each corner sleeve element 7 then comprises two sockets 6 situated in planes at 60 ° around the axis of the member. As can be seen in Figure 4, 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 cross 5.

De plus les axes, X du manchon et Y de chacune des douilles 6, concourent au même point 0 par lequel passe le plan 8 qui limite chaque manchon en direction du manchon voisin. Ainsi le passage de l'entretoise 4 à travers le manchon est-il bien dégagé; de plus lorsque les manchons 7 appartenant à des modules sont accolés de façon que leurs plans 8 soient confondus, chaque point 0 devient un noeud ponctuel d'articulation de la structure en treillis.In addition, the axes, X of the sleeve and Y of each of the sockets 6, compete at the same point 0 through which the plane 8 which limits each sleeve in the direction of the neighboring sleeve passes. Thus the passage of the spacer 4 through the sleeve is it clear; more when the sleeves 7 belonging to modules are joined so that their planes 8 are combined, each point 0 becomes a point node of articulation of the lattice structure.

Dans la réalisation selon la figure 3, l'ensemble de trois panneaux du même étage et des manchons associés constitue un module de contreventement, composé en l'espèce de six manchons 7, trois croisillons 5 et douze entretoises 4.In the embodiment according to FIG. 3, 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.

Pour le montage, les modules de contreventement sont accolés, les manchons 7 appartenant à des modules successifs ayant leurs faces d'extrémité 8 en contact. Après quoi les membrures 2 sont engagées dans les manchons 7 des modules et fixées dans ceux-ci de manière appropriée.For mounting, 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 appropriately.

Membrures, entretoises et manchons peuvent être en matières quelconques pourvu qu'elles se prêtent à l'assemblage par collage, soudure, clavetage, etc.Membranes, spacers and sleeves may be of any material provided that they are suitable for assembly by gluing, welding, keying, etc.

De préférence, tous ces éléments - membrures, entretoises, croisillons et manchons - sont en résine armée de fibres, ce qui permet des assemblages résistants par collage.Preferably, all of these elements - frames, spacers, cross-pieces and sleeves - are made of fiber-reinforced resin, which allows for resistant bonding.

Les membrures et les entretoises sont des tubes pouvant être obtenus par "pultrusion", c'est-à-dire par extrusion combinée avec une traction exercée sur l'extrémité du tube en cours de fabrication. Dans le cas des antennes, ils peuvent être remplis d'une matière alvéolaire 10 formant isolant électrique telle qu'un polyuréthane.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. In the case of antennas, they can be filled with a cellular material 10 forming an electrical insulator such as a polyurethane.

Les croisillons 5 et les manchons 7 peuvent être en matière thermoplastique non rigide, chargée de fibres de verre et moulée par injection. De la sorte, chacun de ces éléments peut jouer dans la structure le rôle d'une articulation au sens de la théorie des treillis articulés; les moments d'encastrement peuvent être considérés comme négligeables et les noeuds étant pnnctuels, les entretoises et les portions libres des membrures sont sollicitées en traction ou en compression.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 nodes being pnnctual, the spacers and the free portions of the members are stressed in tension or in compression.

Lorsque la structure est formée de tronçons, leur assemblage est nécessairement effectué sur le lieu d'utilisation, mais il est préparé en usine.When the structure is formed of sections, their assembly is necessarily carried out at the place of use, but it is prepared in the factory.

Les tronçons une fois assemblés en usine sont démontés pour le transport, qui ne pose donc pas de problèmes. L'invention s'applique aux mâts-supports notamment pour les antennes, aux éléments de charpente provisoire ou définitive et autres applications devant associer légèreté et grande portée.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 large span.
