Description

La présente invention concerne un noeud d'ancrage d'une pluralité de tubes ou de barres métalliques utilisable pour l'assemblage d'un ouvrage de construction, d'une décoration intérieure ou d'un jeu d'ossemblage.The present invention relates to an anchoring node of a plurality of tubes or metal bars usable for the assembly of a construction work, an interior decoration or a game of assembly.

Les méthodes de construction modernes font de plus en plus appel aux structures portantes métalliques tridimensionnelles constituées par des tubes ou des barres métalliques assemblés en résilles modulaires, ces tubes ou ces barres recevant des orientations polydirectionnelles imposées par le système structural choisi. Les points de liaison des tubes ou barres, appelés "noeuds", constituent les éléments les plus importants pour la stabilité et pour les dispositions fonctionnelles des édifices ainsi réalisés. Ces noeuds doivent en effet reprendre non seulement la charge des éléments constitutifs de la structure mais encore des sollicitations extérieures diverses, notamment celles dues au vent.Modern construction methods increasingly use three-dimensional metallic load-bearing structures constituted by metal tubes or bars assembled in modular nets, these tubes or these bars receiving polydirectional orientations imposed by the chosen structural system. The connection points of the tubes or bars, called "nodes", constitute the most important elements for the stability and for the functional arrangements of the buildings thus produced. These nodes must in fact take over not only the load of the constituent elements of the structure but also various external stresses, in particular those due to the wind.

En général, les noeuds consistent en des pièces métalliques de forme géométrique adaptée aux orientations que doivent prendre les tubes ou les barres à assembler, ceux-ci étant ensuite solidarisés au moyen de plusieurs boulons ou par soudage. Il en résulte que le montage est lent et compliqué du fait de la multiplicité des peints d'attache. Par ailleurs, la forme des noeuds utilisés ne se prêtent guère à de grandes variations quant aux directions des éléments à assembler.In general, the nodes consist of metallic parts of geometric shape adapted to the orientations which the tubes or the bars to be assembled must take, these being then joined by means of several bolts or by welding. As a result, assembly is slow and complicated due to the multiplicity of attachment paints. Furthermore, the shape of the nodes used hardly lend themselves to large variations in the directions of the elements to be assembled.

La présente invention vise à remédier à ces inconvénients en procurant des noeuds d'ancrage offrant de multiples possibilités directionnelles pour les tubes ou barres à assembler, assurant une stabilité efficace et maintenant les divers éléments e:. place par un seul moyen de fixation, ce qui permet d'accélérer le montage tout er. lui donnant une grande souplesse.The present invention aims to remedy these drawbacks by providing anchoring nodes offering multiple directional possibilities for the tubes or bars to be assembled, ensuring effective stability and maintaining the various elements e :. place by a single fastening means, which allows to accelerate the er er assembly. giving it great flexibility.

L'invention concerne, en fait, un noeud d'ancrage d'une pluralité de tubes ou de barres métalliques utilisable pour l'assemblage d'une structure tridimensionnelle pour un ouvrage ie construction ou une décoration intérieure, ledit noeud con- sistant en un ensemble sphérique plein qui comporte une pièce centrale formant le noyau du noeud et une partie médiane de la surface de la sphère, entourée d'un certain nombre de coquilles formant dans la sphère une coupole supérieure et une coupole inférieure, les différentes pièces constituant cet ensemble étant moulées en un alliage coulable à chaud en des formes à bords non rectilignes capables de s'intégrer étroitement et fermement les unes aux autres en réalisant une sphère pleine cohérente :nais en laissant toutefois une multiplicité d'orifices de pénétration et des surfaces d'appui et de retenue pour des embouts à téton solidarisés chacun à un des tubes ou une des barres métalliques à assembler, le tout étant rendu cohérent par un moyen de fixation unique.The invention relates, in fact, to an anchoring knot of a plurality of tubes or metal bars usable for assembling a three-dimensional structure for a work ie construction or interior decoration, said node con- s istant in a full spherical assembly comprising a central component forming the core node and a middle portion of the surface of the sphere, surrounded by a number of shells forming in the sphere an upper dome and a lower dome, the various parts constituting this set being molded from a hot-pourable alloy into shapes with non-rectilinear edges capable of integrating tightly and firmly with each other by producing a coherent solid sphere: nais however, leaving a multiplicity of penetration orifices and bearing and retaining surfaces for nipple ends each secured to one of the tubes or one of the metal bars to be assembled, the whole being made coherent by a single fixing means.

Suivant une forme d'exécution avantageuse de l'invention, on assure une bonne cohésion entre le noyau central et les coquilles en donnant aux bords et aux surfaces de contact de la pièce centrale et des coquilles un tracé plus ou moins sinusoïdal. Ceci permet d'éviter le glissement des pièces les unes sur les autres.According to an advantageous embodiment of the invention, good cohesion is ensured between the central core and the shells by giving the edges and the contact surfaces of the central part and the shells a more or less sinusoidal outline. This prevents parts from sliding over each other.

La pièce centrale peut être entourée de deux à quatre coquilles formant des coupoles supérieure et inférieure.The central part can be surrounded by two to four shells forming upper and lower domes.

Les orifices de pénétration des embouts à téton qui pro- longent les tubes ou les barres sont réalisés par la superposi- ticn d'encoches spécialement prévues à cet effet dans les parties de la pièce centrale et des coquilles avoisinant la surface extérieure de la sphère. Ces orifices ont un diamètre un peu supérieur à celui de l'extrémité de l'embout (avant le téton) et sont suivis dans le noeud, à une distance suffisante pour la solidité, par une cavité plus spacieuse permettant de loger et de retenir le téton de l'embout. Il va de soi que lesdits embouts doivent être placés dans le noeud avant la fermeture définitive du noeud sphérique.The penetrations of the nipple ends which extend along the tubes or the bars are made by superimposing notches specially provided for this purpose in the parts of the central part and of the shells surrounding the outer surface of the sphere. These orifices have a diameter slightly greater than that of the end of the end piece (before the nipple) and are followed in the knot, at a distance sufficient for solidity, by a more spacious cavity making it possible to house and retain the tip nipple. It goes without saying that said tips must be placed in the knot before the final closure of the spherical knot.

Selon un mode de réalisation avantageux de l'invention, le moyen de fermeture du noeud, c'est-à-dire le moyen de fixation unique des divers éléments de l'ensemble, consiste en un boulon noyé ou en une fixation rapide ("clips") placé de manière à pénétrer dans tous les éléments.According to an advantageous embodiment of the invention, the means of closing the node, that is to say the means of single fixing of the various elements of the assembly, consists of a submerged bolt or a quick fixing ("clips") placed so as to penetrate all the elements.

Dons certains cas, par exemple si l'assemblage est susceptible de subir de fortes sollicitotions, le moyen de fixation unique des divers éléments de l'ensemble peut être réalisé par soudage.In some cases, for example if the assembly is likely to be subjected to high stresses, the single means of fixing the various elements of the assembly can be produced by welding.

On a vu que les divers éléments du noeud sont moulés en un alliage coulable à chaud. On peut mentionner à titre d'exemple l'utilisation de l'acier ou d'une matière synthétique plcstique.We have seen that the various elements of the knot are molded from a hot-cast alloy. By way of example, mention may be made of the use of steel or of a plastic synthetic material.

Il est avantageux que les embouts des tubes ou des barres à assembler présentent un téton raccordé par l'intermédiaire l'une surface en biseau à une partie cylindrique raccordée elle-même à une partie tronconique associée au tube ou à la barre. On offre ainsi une meilleure résistance aux efforts et on facilite l'autoblocage des embouts.It is advantageous that the ends of the tubes or bars to be assembled have a stud connected via one beveled surface to a cylindrical part itself connected to a frustoconical part associated with the tube or the bar. This provides better resistance to forces and facilitates the self-locking of the tips.

Les noeuds d'ancrage de la présente invention peuvent notamment être utilisés pour l'assemblage de tubes ou de barres métalliques formant la charpente d'une construction. Ils peuvent aussi être employés pour l'érection de serres ou de halls de toute nature, notamment des halls industriels, des préaux d'écoles, etc. Ils peuvent également servir à la réalisation d'une structure tridimensionnelle de décoration intérieure.The anchor nodes of the present invention can in particular be used for the assembly of tubes or metal bars forming the frame of a construction. They can also be used for the erection of greenhouses or halls of all kinds, in particular industrial halls, school yards, etc. They can also be used to create a three-dimensional structure for interior decoration.

On va décrire à présent, à titre d'exemple non limitatif, des exemples de réalisation de l'invention illustrés dans les figures ci-annexées.We will now describe, by way of nonlimiting example, exemplary embodiments of the invention illustrated in the attached figures.

Dans ces figures :

  • - la figure 1 montre une vue en élévation d'un noeud d'ancrage conforme à l'invention,
  • - la figure 2 représente une vue en perspective éclatée d'un noeud de l'invention reliant six tubes métalliques,
  • - la figure 3 montre la partie centrale du noeud de la figure 2 en une coupe verticale effectuée dans le plan AAAA de la figure 2,
  • - la figure 4 représente,en coupe verticale, les coupoles supérieure et inférieure du noeud de la figure 2 ainsi que le boulon unique de fixation.
  • - la figure 5 montre la partie centrale du noeud de la figure 2 en une coupe oblique effectuée dans le plan BBBB de la figure 2 et
  • - la figure 6 montre le noeud de l'invention, en vue en plan, coupole supérieure enlevée, raccordé à huit embouts.
In these figures:
  • FIG. 1 shows an elevation view of an anchoring node according to the invention,
  • FIG. 2 represents an exploded perspective view of a node of the invention connecting six metal tubes,
  • FIG. 3 shows the central part of the node of FIG. 2 in a vertical section made in the plane AAAA of FIG. 2,
  • - Figure 4 shows, in vertical section, the upper and lower domes of the node of Figure 2 and the single fixing bolt.
  • FIG. 5 shows the central part of the node of FIG. 2 in an oblique section made in the plane BBBB of FIG. 2 and
  • - Figure 6 shows the node of the invention, in plan view, upper dome removed, connected to eight tips.

La figure 1 représente un noeud d'ancrage de l'invention, fermé mais non raccordé à des tubes ou des barres. On peut distinguer, dans cette vue en élévation, la partie centrale ou ncyau du noeud 1, la coupole supérieure 2 et la coupole inférieure 3. Tous ces éléments sont fabriqués, par exemple, en ccier ou en nylon. Les surfaces hachurées 4 indiquent les orifices de pénétration des embouts, orifices formés par la superposition d'encoches prévues à cet effet dans la partie centrale 1 et dans les coupoles 2, 3.Figure 1 shows an anchor node of the invention, closed but not connected to tubes or bars. We can distinguish, in this elevation view, the central part or nc y au of node 1, the upper dome 2 and the lower dome 3. All these elements are made, for example, of steel or nylon. The hatched surfaces 4 indicate the holes for penetration of the end pieces, holes formed by the superposition of notches provided for this purpose in the central part 1 and in the domes 2, 3.

La figure 2 donne une vue en perspective du noeud de l'invention, la coupole supérieure 2 étant soulevée pour faciliter la vision de six embouts 5 de tubes métalliques 6 ancrés dans le noeud. Deux autres embouts, non visibles sur cette figure, sont encore raccordés de l'autre côté du noeud (voir figure 6). On distingue bien dans cette figure la forme des embouts 5 : partie tronconique raccordée au tube 6, suivie d'une partie cylindrique et d'un téton raccordé à la partie cylindrique par une surface en biseau qui améliore la resistance aux efforts et facilite l'autoblocage des embouts. On voit aussi que les tétons des embouts sont plus grands que les orifices de pénétration et sent retenus dès lors, après fermeture du noeud, par l'épaisseur 7 laissée entre la surface de la sphère-et le logement du téton.Figure 2 gives a perspective view of the node of the invention, the upper dome 2 being raised to facilitate the vision of six end pieces 5 of metal tubes 6 anchored in the node. Two other end pieces, not visible in this figure, are also connected on the other side of the node (see Figure 6). We can clearly see in this figure the shape of the end pieces 5: frustoconical part connected to the tube 6, followed by a cylindrical part and a stud connected to the cylindrical part by a bevelled surface which improves the resistance to the forces and facilitates the self-locking tips. We also see that the nipples of the tips are larger than the penetration holes and feels retained therefore, after closing the node, by the thickness 7 left between the surface of the sphere and the housing of the nipple.

La figure 3 représente, en coupe verticale , la partie centrale 1 du noeud de la figure 2 suivant le plan AAAA. On distingue deux embouts 5. Les axes 8 sont les axes de barres obliques. Cette partie centrale constitue le noyau du noeud et est pleine.Figure 3 shows, in vertical section, the central part 1 of the node of Figure 2 along the AAAA plane. There are two tips 5. The axes 8 are the axes of slashes. This central part constitutes the core of the node and is full.

La figure 4 représente, en coupe verticale, les coupoles supérieure 2 et inférieure 3 d'un noeud de l'invention. Elle montre aussi le boulon 9 et son écrou de serrage 10 qui assurent, à eux seuls, la fermeture de la cohésion du noeud.FIG. 4 represents, in vertical section, the upper 2 and lower 3 domes of a node of the invention. It also shows the bolt 9 and its tightening nut 10 which, by themselves, ensure the closure of the cohesion of the node.

La figure 5 montre la partie centrale 1 du noeud de la figure 2 en une coupe oblique effectuée selon le plan BBBB de la figure 2. On y voit les embouts 5 des barres obliques et, en ligne interrompue, le passage pour le boulon de serrage.Figure 5 shows the central part 1 of the node of Figure 2 in an oblique section made along the plane BBBB of Figure 2. We see the ends 5 of the oblique bars and, in broken line, the passage for the tightening bolt .

La figure 6 montre le noeud de l'invention, en vue en plan, coupole supérieure enlevéee, raccordée à huit embouts. Les embouts 51 sont ceux des tubes horizontaux et les embouts 5" se rapportent à des tubes obliques.Figure 6 shows the node of the invention, in plan view, upper dome removed, connected to eight tips. The end pieces 5 1 are those of the horizontal tubes and the end pieces 5 "relate to oblique tubes.

L'invention n'est évidemment pas limitée à l'exemple de réalisation qui vient d'être décrit. On peut faire varier notamment le nombre de coquilles, la forme du tracé de séparation entre les éléments du noeud, en fonction des angles désirés pour les barres, le nombre des orifices de pénétration des embouts et leur orientation, la nature de l'alliage coulable à chaud utilisé pour le moulage des éléments, etc. Les dimensions des noeuds peuvent varier suivant leur destination et le nombre des tubes ou des barres qu'ils doivent raccorder; cette notion est indépendante du principe de la présente invention.The invention is obviously not limited to the embodiment which has just been described. We can vary in particular the number of shells, the shape of the separation path between the elements of the node, depending on the desired angles for the bars, the number of holes for penetration of the tips and their orientation, the nature of the castable alloy hot used for molding elements, etc. The dimensions of the nodes can vary according to their destination and the number of tubes or bars they must connect; this notion is independent of the principle of the present invention.
