Abstract
Description
L'invention concerne un système de liaison multidirectionnelle pour structures comprenant une pièce de liaison sur laquelle viennent se fixer des barres définissant la structure selon le préambule de la revendication 1.The invention relates to a multidirectional connection system for structures comprising a connection piece to which bars defining the structure are fixed according to the preamble of claim 1.
La conception et la réalisation d'une structure doit satisfaire à des conditions de stabilité :
- - statique, afin que, quelle que soit la variation angulaire des lignes de force, celles-ci restent toujours concourantes en un point ; que les flux des contraintes ne rencontrent pas de discontinuités et que, dans les zones de concours, les contraintes soient dissipées dans la masse en évitant les phénomènes de concentration ;
- - dynamique par la possibilité d'assembler isostatiquement les composants entre eux ;
- - au feu, en remédiant à l'affaissement des caractéristiques mécaniques sous températures élevées par augmentation des épaisseurs et diamètres des éléments constitutifs.
- - static, so that, whatever the angular variation of the lines of force, these always remain concurrent at a point; that the stress flows do not encounter discontinuities and that, in the competition areas, the stresses are dissipated in the mass, avoiding the phenomena of concentration;
- - dynamic by the possibility of isostatically assembling the components together;
- - fire, by remedying the subsidence of mechanical characteristics at high temperatures by increasing the thicknesses and diameters of the constituent elements.
La construction des structures pose actuellement des problèmes au niveau des matériaux de construction, et notamment en ce qui concerne les pièces de liaison. Généralement ces pièces sont fabriquées spécialement et sont différentes selon leur place dans la structure. De telles contraintes aboutissent à un maintien élevé des prix de revient, à des temps de mise en oeuvre longs et à une grande difficulté de modification ou de récupération de structures existantes.The construction of structures currently poses problems in terms of construction materials, and in particular as regards the connecting parts. Generally these parts are specially made and are different depending on their place in the structure. Such constraints result in a high maintenance of cost prices, long implementation times and great difficulty in modifying or recovering existing structures.
Le brevet français 1 520 550 décrit un dispositif d'assemblage creux permettant la circulation d'un fluide entre éléments concourants. Le noeud d'assemblage comporte un corps central creux sur lequel sont fixées des ailettes, selon des plans longitudinaux orthogonaux passant par l'axe du corps creux et par le centre des ouvertures pour le passage du fluide.French patent 1,520,550 describes a hollow assembly device allowing the circulation of a fluid between concurrent elements. The assembly node comprises a hollow central body on which the fins are fixed, along orthogonal longitudinal planes passing through the axis of the hollow body and through the center of the openings for the passage of the fluid.
Les ailettes se prolongent également sur les faces transversales du corps creux. En face des ouvertures et sur les ailettes sont prévus des trous pour la fixation des tubes de structures dont l'extrémité est conformée pour s'adapter exactement sur les bords des ailettes et dans les ouvertures. Les tubes ont alors une direction unique déterminée lors de la construction du noeud par les positions relatives de l'ouverture du corps central, du trou de fixation dans l'ailette et du bord de l'ailette. Il n'y a aucune possibilité de modifier les angles entre deux couronnes.The fins also extend on the transverse faces of the hollow body. In front of the openings and on the fins are provided holes for fixing the structural tubes, the end of which is shaped to fit exactly on the edges of the fins and in the openings. The tubes then have a single direction determined during the construction of the node by the relative positions of the opening of the central body, of the fixing hole in the fin and of the edge of the fin. There is no possibility to modify the angles between two crowns.
Un autre dispositif d'assemblage, décrit dans le brevet français 2079817, est constitué d'un corps en forme de plaque circulaire dont une face porte des segments d'anneaux cylindriques. Le corps peut recevoir deux formes d'ailettes : une destinée à des liaisons dans le plan de la plaque comportant un étrier prolongé par une queue servant à la fixation des éléments de structure ; une autre destinée à des liaisons inclinées sur le plan de la plaque comportant un secteur circulaire, susceptible de coopérer avec les faces du corps central, sur lequel est fixé obliquement une queue. Chaque ailette est fixée séparément sur le corps central à l'aide de boulons.Another assembly device, described in French patent 2079817, consists of a body in the form of a circular plate, one face of which carries segments of cylindrical rings. The body can receive two forms of fins: one intended for connections in the plane of the plate comprising a stirrup extended by a tail used for fixing the structural elements; another intended for inclined connections on the plane of the plate comprising a circular sector, capable of cooperating with the faces of the central body, on which a tail is fixed obliquely. Each fin is attached separately to the central body using bolts.
Les ailettes déterminent une direction unique de fixation des éléments de structure. En outre, l'angle que font les ailettes d'une couronne par rapport aux ailettes de l'autre couronne est défini par construction et ne peut être modifié.The fins determine a single direction of attachment of the structural elements. In addition, the angle which the fins of one crown make with respect to the fins of the other crown is defined by construction and cannot be modified.
L'invention vise à la réalisation d'un système de liaison multidirectionnelle apportant une grande souplesse d'utilisation et se présentant sous forme d'éléments standardisés.The invention aims to achieve a multidirectional connection system providing great flexibility of use and in the form of standardized elements.
Le système de liaison multidirectionnelle pour structure selon l'invention, est caractérisé en ce que le corps central est séparable en au moins deux parties, selon un plan transversal, chacune des parties portant une couronne d'oreilles et en ce que les faces coopérantes des parties du corps central portent des moyens de positionnement permettant des décalages angulaires d'une couronne par rapport à l'autre.The multidirectional connection system for structure according to the invention is characterized in that the central body can be separated into at least two parts, along a transverse plane, each of the parts carrying a ring of ears and in that the cooperating faces of the parts of the central body carry positioning means allowing angular offsets of one crown relative to the other.
Selon des formes de réalisation, les plans des oreilles passent par l'axe du corps central ou coupent ledit axe.According to embodiments, the planes of the ears pass through the axis of the central body or intersect said axis.

La pièce de liaison 1 forme un noeud auquel sont reliées les barres 2 et 3 définissant la structure.The connecting piece 1 forms a node to which the
La pièce de liaison 1 comporte un corps central 4 sur lequel sont fixées des oreilles 5, 6 formant deux couronnes 7 et 8 superposées. Les oreilles 5 de la couronne 7 sont angulairement décalées des oreilles 6 de la couronne 8.The connecting piece 1 comprises a central body 4 on which are fixed ears 5, 6 forming two superimposed
Selon une forme de réalisation préférée : les oreilles 5 de la couronne 7 sont de forme symétrique approximativement rectangulaire, l'axe moyen équidistant des grands côtés coupant l'axe du corps central et les grands côtés des oreilles 6 de la couronne 8 font des angles aigus avec l'axe du corps central, l'axe moyen approximativement équidistant des deux grands côtés coupe l'axe du corps central au même point que l'axe moyen des oreilles 5 de la couronne 7, ce qui conduit à ce que les axes (lignes de force des barres de la structure) se fixant sur les oreilles peuvent être tous concourants en un point sur l'axe du noyau.According to a preferred embodiment: the ears 5 of the
Le nombre des oreilles de chaque couronne a été arbitrairement choisi égal à 4 et le décalage angulaire entre les oreilles de chaque couronne de 45°. Dans cet exemple, comme dans ceux qui vont suivre, le nombre des oreilles de chaque couronne peut être quelconque, le nombre des oreilles d'une couronne n'étant pas nécessairement égal au nombre des oreilles de l'autre, et les décalages angulaires entre les oreilles de chaque couronne ne donnant pas obligatoirement une répartition équidistante des oreilles autour du corps central.The number of ears of each crown was arbitrarily chosen equal to 4 and the angular offset between the ears of each crown of 45 °. In this example, as in those which will follow, the number of ears of each crown can be arbitrary, the number of ears of one crown not necessarily being equal to the number of ears of the other, and the angular offsets between the ears of each crown do not necessarily give an equidistant distribution of the ears around the central body.
La réalisation des figures 2A et 2B comporte un corps central séparable en au moins deux parties 11 et 12. Chacune des parties porte à sa périphérie les oreilles qui sont soit soudées, soit venues directement de moulage. Les faces coopérantes 13 et 14 des deux parties du corps central portent des moyens de positionnement angulaire d'une couronne par rapport à l'autre. Selon une réalisation classique, une partie 15 des oreilles de la partie 12 s'engage dans des fentes 16 prévues dans la couronne 11. Les parties de corps central portent, suivant leur axe, un trou de centre et/ou un alésage 17 dans lequel peut être introduite une pièce de fixation, par exemple un boulon, permettant de bloquer les deux parties dans la position voulue. La partie 11 peut présenter à sa partie supérieure des fentes (représentées en trait interrompu) semblables aux fentes 16 et recevoir un autre élément 12.The embodiment of FIGS. 2A and 2B comprises a central body separable into at least two
Les trous de centre et/ou alésages 17 matérialisent l'axe du corps central et permettent le perçage précis des oreilles.The center holes and / or
Un autre exemple d'un corps central en deux parties est montré dans les figures 3A et 3C. La partie 18 comporte six oreilles et la partie 19 (figure 3C) trois oreilles. Des moyens de positionnement, constitués par exemple d'un ergot 20 dans la partie 18 et de logements 21, permettent des décalages angulaires différents suivant l'utilisation de la pièce de liaison. Selon une autre forme de réalisation (figures 4A à 4E), le corps central est constitué de deux parties semblables 22 et 23 (figures 4A et 4B) sur la surface latérale desquelles on a prévu des rainures 24 parallèles à l'axe du corps central et qui pénètrent dans le corps (figure 4C). Les rainures reçoivent ou positionnent les bases 25 et 26 des oreilles qui y sont maintenues, par exemple, par collage, le corps étant de préférence en matière plastique. Les surfaces de base 27 et 28 des parties de corps portent un ergot 29 et un logement 30 en forme de demi-couronne coaxiale. Vus de dessus, l'ergot et le logement (figure 4C) sont disposés selon une couronne. Les parties de corps portant les oreilles (figures 4D et 4E) sont assemblées, de manière connue, pour former une pièce de liaison. Comme précédemment décrit, les faces des oreilles portent des marques 31 facilitant par positionnement une plage de perçage des oreilles pour recevoir les barres de structure.Another example of a two-part central body is shown in Figures 3A and 3C.
Dans l'exemple des figures 5A à 5D, le corps central est formé d'au moins deux parties 32 et 33, chaque partie portant une rainure périphérique 34 dont le plan de symétrie est perpendiculaire à l'axe du corps central. La rainure est plus large dans le fond qu'à la surface du corps. Les bases des oreilles 37 et 38 présentent des formes approximativement complémentaires de celles des rainures avec lesquelles elles coopérent. Dans cette réalisation, chaque partie 32, 33 du corps central est constituée de deux pièces 39, 40 symétriques ou identiques. Le maintien des pièces l'une par rapport à l'autre est obtenu par les mêmes moyens que ceux décrits dans les figures précédentes 7A à 7E qui présentent deux parties 41 et 42 en demi-couronne faisant office d'ergot et de logement (figure 5D).In the example of FIGS. 5A to 5D, the central body is formed of at least two
Lorsque les pièces sont assemblées, elles définissent une rainure 34 dont la section est approximativement en forme de T, la barre transversale du T étant parallèle à l'axe du corps central et proche de son axe. Les pièces d'extrémité, telle que la pièce 39, présentent sur leur face libre 43 un évidement 44 coaxial à un alésage axial 45. Les bases 35 et 36 des oreilles 37 et 38 sont présentées sur les pièces 40 assemblées dos à dos et sont maintenues par les pièces 39 lors de l'assemblage de la pièce de liaison. Les oreilles peuvent se déplacer le long des rainures dans un plan passant par l'axe du corps central ou faire éventuellement un angle avec cet axe et, lorsque les barres sont fixées, se mettre dans la position du minimum d'efforts.When the parts are assembled, they define a
Les figures 6A et 6C montrent une réalisation dans laquelle le corps central est formé de deux parties symétriques 46 et 47, chacune des parties présentant une rainure périphérique 48 de section approximativement rectangulaire, dont le plan de symétrie est perpendiculaire à l'axe du corps central, le fond de la rainure présentant une nervure 49 plus large en surface qu'en fond et en particulier de section en T, la barre verticale du T ou pied étant fixée sur le fond de la rainure perpendiculairement à l'axe du corps central, la barre transversale du T étant parallèle à l'axe du corps central et affleurant aux bords de la rainure. La partie périphérique de la nervure porte au moins un passage 50 de dimensions égales à la dimension du fond de rainure susceptible de laisser passer la base des oreilles présentant une forme approximativement complémentaire de la rainure et de sa nervure.FIGS. 6A and 6C show an embodiment in which the central body is formed of two
La figure 6C montre en coupe une réalisation dans laquelle la nervure est discontinue et s'étend, par exemple, sur deux ou quatre secteurs de chaque partie du corps central. Chacun des secteurs est séparé du suivant par une paroi longitudinale 51 qui assure une plus grande rigidité de l'ensemble lors de l'assemblage.FIG. 6C shows in section an embodiment in which the rib is discontinuous and extends, for example, over two or four sectors of each part of the central body. Each of the sectors is separated from the next by a
Les oreilles des pièces de liaison sont fixées aux tubes de la structure au moyen de pièces de fixation 52 (figures 1, 7A, 7B). Selon l'exemple de réalisation représenté, cette pièce comporte au moins une chape 53 traversée par un alésage 54 qui est mis en concordance avec l'alésage de l'oreille percé en fonction des données du calcul d'application des forces. La barre 2 de liaison de la structure peut être soudée directement à cette chape ou être maintenue.The ears of the connecting pieces are fixed to the tubes of the structure by means of fixing pieces 52 (FIGS. 1, 7A, 7B). According to the embodiment shown, this part comprises at least one
La pièce de fixation 52 porte, dans la réalisation représentée, une deuxième chape 55 d'axe perpendiculaire à celle coopérant avec l'oreille. La chape 55 peut être percée d'un alésage 56 traversant ou non et qui peut recevoir un dispositif permettant l'irrigation par un fluide de la barre ou encore (figure 7A) des moyens de raccordement étanches 57 et correspond avec un perçage de la barre de structure pour assurer le passage d'un fluide de refroidissement ou caloporteur.The
La figure 1 montre un noeud de liaison dans lequel toutes les pièces de fixation 52 comportent des moyens de raccordement qui sont reliés entre eux par des tuyaux 58 aboutissant à une boîte de raccordement ou de distribution 59, qui est éventuellement reliée à la source de fluide caloporteur de refroidissement ou de chauffage de la structure. Le système de liaison multidirectionnelle selon l'invention permet d'utiliser les barres de structure pour véhiculer des fluides et en particulier de disposer d'un réseau de lutte contre l'incendie efficace par le refroidissement des barres et par l'utilisation d'au moins un alésage de chape comme dispositif d'arrosage. Les applications du système de liaison sont très nombreuses et en particulier permettent la réalisation de structures à double courbure de deux nappes à épaisseur variable, telles qu'utilisées dans les réfrigérants statiques, en influant ou non sur l'effet Venturi, ou dynamiques, de faîtages de type shed « Tuile permettant une grande facilité de transformation et pouvant être entièrement assemblées au sol avec tous les composants et accessoires (couverture, tuyauterie...).FIG. 1 shows a connection node in which all the fixing
La standardisation des pièces de liaison permet une diminution des délais entre le moment de la conception et celui de la livraison de la structure, elle permet également un moindre coût par l'universalité des composants de la structure.The standardization of the connecting parts allows a reduction of the time periods between the moment of design and that of the delivery of the structure, it also allows a lower cost by the universality of the components of the structure.
Selon la forme de réalisation représentée figures 8A-8B, le corps central de la pièce de liaison est réalisé en au moins deux parties superposables, chacune des parties portant une couronne d'oreilles 63, 64. La partie 64 présente des oreilles 58 dont les plans sont, selon l'exemple, verticaux. Le corps central 59 porte des logements 60 dans lesquels sont susceptibles de pénétrer des ergots 61 prévus sur une des faces de la deuxième couronne d'oreilles représentée figure 8B. Les logements prévus sur les deux faces planes et parallèles du corps central 59 permettent la réalisation d'une pièce de liaison à trois couronnes d'oreilles : une couronne centrale 64 conforme à la figure 8A et deux couronnes, une supérieure 62 et une inférieure 63 conformes à la figure 8B. La couronne centrale 64 peut être réalisée selon un des exemples des figures 4A, 5A, 6A avec des oreilles amovibles. Le corps central d'où partent les oreilles 58 est cylindrique ou polygonal et est percé selon son axe par un canal 65 au moins en partie de forme polygonale.According to the embodiment shown in Figures 8A-8B, the central body of the connecting piece is made of at least two superimposable parts, each of the parts carrying an
La partie de pièce représentée figure 8B est formée d'un corps central 66 d'où partent des oreilles 67 dont la direction par rapport aux plans parallèles du corps central fait un angle aigu. Selon une particularité de cette réalisation, le corps central est approximativement tronconique, l'angle du cône permettant une transmission égale des efforts de traction ou de compression s'exerçant sur les oreilles de manière que le point de concours des forces soit au centre O de la pièce de liaison. Ce point 0 est situé à l'intérieur de la partie du corps central et correspond au point de concours des forces de la couronne médiane d'oreilles 64.The part part shown in FIG. 8B is formed by a
Le corps tronconique porte, sur sa base la plus large, les ergots 61 de forme correspondant à celle des logements 60 de la couronne médiane 64, et selon son axe longitudinal, un canal 68 de forme polygonale de section égale à celle du canal 65 de la couronne 64.The frustoconical body carries, on its widest base, the
Selon l'exemple de la figure 8B, la surface latérale du corps central est concave, ce qui permet un allégement de la pièce et une meilleure répartition des forces s'exerçant à l'extrémité des oreilles.According to the example of FIG. 8B, the lateral surface of the central body is concave, which allows a reduction in the workpiece and a better distribution of the forces exerted at the end of the ears.
Selon des formes de réalisation du corps central de la couronne centrale ou des couronnes supérieure et/ou inférieure, au moins une partie du corps est définie par un volume de révolution de section circulaire ou polygonale dont la génératrice est formée par au moins une courbe ou une droite ou par une combinaison de courbes et/ou de droites.According to embodiments of the central body of the central crown or of the upper and / or lower crowns, at least one part of the body is defined by a volume of revolution of circular or polygonal cross section whose generatrix is formed by at least one curve or a straight line or by a combination of curves and / or straight lines.
La figure 9 est une vue de dessus d'une couronne médiane 64 et d'une couronne inférieure 63. Les deux parties de la pièce de liaison sont solidarisées par un moyen de serrage, tel que vis et écrou passant dans le canal axial 65, 68. Ce canal axial reçoit éventuellement une pièce de positionnement 69 de forme correspondante à celle du canal et maintenant les couronnes d'oreilles en position les unes par rapport aux autres. Dans le cas de l'exemple, la pièce de positionnement 69 renforce le dispositif de positionnement angulaire formé par les logements 60 et les ergots 61.FIG. 9 is a top view of a
Selon une autre réalisation non représentée, le dispositif 60, 61 est remplacé par la pièce de positionnement 69.According to another embodiment, not shown, the
Comme dans les exemples précédents, la forme des oreilles est prévue de manière à permettre un positionnement des barres de structure pouvant présenter des écarts angulaires a1, a2, b1, b2 donnés par rapport à l'axe moyen de l'oreille ao, bo en conservant le concours en un même point 0 situé sur l'axe du corps central 14.As in the previous examples, the shape of the ears is provided so as to allow positioning of the structural bars which may have angular deviations a 1 , a 2 , b 1 , b 2 given relative to the mean axis of the ear a o , b o keeping the competition at the same point 0 located on the axis of the central body 14.
Dans l'exemple de réalisation des figures 8A, 8B, les oreilles des couronnes centrale et inférieure et/ou supérieure peuvent être agrandies jusqu'à une limite correspondant approximativement à la tangence des bords voisins 70, 71 des oreilles de couronnes adjacentes 64, 63 et 62, 64. Cette particularité permet de placer des oreilles des couronnes inférieure et/ou supérieure dans le même plan qu'une ou plusieurs oreilles de la couronne centrale. Si l'on ne désire pas obtenir un positionnement continu sur 360°, les oreilles des couronnes inférieure et/ou supérieure peuvent s'interpénéter comme le montrent les figures 2A, 2B ; 3A, 3B ; 5A, 6A.In the embodiment of FIGS. 8A, 8B, the ears of the central and lower and / or upper crowns can be enlarged to a limit corresponding approximately to the tangency of the neighboring
Selon une autre forme de réalisation non représentée, les bords 72 des oreilles des couronnes inférieure 63 et supérieure 62 peuvent à la limite être parallèles à l'axe de la pièce centrale.According to another embodiment, not shown, the
