Description

La présente invention est relative à un dispositif d'assemblage multidirectionnel pour des constructions métalliques. Elle s'applique plus particulièrement à la réalisation d'ossatures et de constructions métalliques pouvant être utilisées pour des applications multiples, fixes ou provisoires, telles que notamment supports de couverture pour bâtiments de petite et grande portée, façades, auvents, abris, stands, pylones, plafonds décoratifs et tous ensembles d'équipements divers.The present invention relates to a multidirectional assembly device for metal constructions. It applies more particularly to the production of metal frames and constructions which can be used for multiple applications, fixed or temporary, such as in particular covering supports for buildings of small and large span, facades, awnings, shelters, stands, pylons, decorative ceilings and all sets of various equipment.

Ces réalisations entre dans la constitution de structures tridimensionnelles, formées de nappes ou résilles superposées, composées d'éléments ou barres situés dans un plan et reliés entre eux par des éléments situés dans des plans différents et orientés dans diverses directions de l'espace, appelés diagonales.These realizations enter into the constitution of three-dimensional structures, formed of superimposed sheets or nets, composed of elements or bars located in a plane and linked together by elements located in different planes and oriented in various directions of space, called diagonals.

Pour bien faire comprendre le domaine d'application de la présente invention on peut se référer aux figures 1 et 2 des dessins annexés sur lesquelles on a représenté respectivement en coupe suivant A-A et en plan une structure tridimensionnelle à laquelle s'applique l'invention.To clearly understand the field of application of the present invention, reference can be made to Figures 1 and 2 of the accompanying drawings in which there is shown respectively in section along A-A and in plan a three-dimensional structure to which the invention applies.

Sur ces figures la référence 10 désigne la structure composée de nappes superposées 12, 12′, situées dans des plans parallèles P1, P2 et constituées d'éléments ou barres 18 reliés par des diagonales 14. La jonction ou noeud de ces éléments, désigné par la référence 16 constitue l'objet de la présente invention.In these figures the reference 10 designates the structure composed of superimposed layers 12, 12 ′, located in parallel planes P1, P2 and made up of elements or bars 18 connected by diagonals 14. The junction or node of these elements, designated by reference 16 constitutes the object of the present invention.

Cette invention a donc pour objet un dispositif d'assemblage multidirectionnel pour constructions métalliques entrant dans la constitution de structures tridimensionnelles formées de nappes ou résilles superposées, d'éléments ou barres situés dans un même plan et reliés entre eux par des éléments situés dans des plans différents et orientés dans diverses directions de l'espace, ces divers éléments étant raccordés à l'aide de noeuds d'assemblage, ce dispositif étant caractérisé en ce que chaque noeud d'assemblage est réalisé sous la forme d'une sphère percée radialement de trous taraudés dans lesquels viennent se positionner et se fixer les éléments constituants des nappes ou résilles.The subject of this invention is therefore a multidirectional assembly device for metal constructions used in the constitution of three-dimensional structures formed of superimposed sheets or nets, of elements or bars located in the same plane and connected together by elements located in planes different and oriented in different directions of space, these various elements being connected using assembly nodes, this device being characterized in that each assembly node is produced in the form of a sphere pierced radially by threaded holes in which are positioned and fixed the constituent elements of the sheets or nets.

Comme on le comprend le but de l'invention réside dans la fixation sur une sphère, par les moyens les plus simples des multiples éléments ou barres de la structure, pouvant se situer dans toutes le directions de l'espace. Pour mener à bien l'aboutissement de la présente invention on a tenu compte notamment des facteurs suivants esthétique, respect impératif des épures et de l'élimination des efforts secondaires, simplicité de fabrication, application dans les meilleures conditions de la protection des matériaux constituants la structure (notamment l'acier) et facilité du transport, du montage et du rattrapage de jeux éventuels.As can be understood, the object of the invention lies in the attachment to a sphere, by the simplest means, of the multiple elements or bars of the structure, which can be located in all directions of space. To successfully complete the present invention, particular account was taken of the following aesthetic factors, imperative respect for the drawings and the elimination of secondary forces, simplicity of manufacture, application in better conditions for the protection of the materials constituting the structure (in particular steel) and ease of transport, mounting and taking up any play.

  • - la figure 6 est une coupe selon C-C de la figure 5.
Other characteristics and advantages of the present invention will emerge from the description given below with reference to the appended drawings which illustrate an embodiment thereof devoid of any limiting character. In the drawings:
  • - Figure 1 is a sectional view along AA of Figure 2 showing a three-dimensional structure described above and to which the invention applies;
  • - Figure 2 is a plan view of the three-dimensional structure illustrated in Figure 1;
  • - Figure 3 is an enlarged view showing in detail an assembly node according to the invention of the three-dimensional structure shown in Figures 1 and 2;

  • - Figure 5 is a sectional view along BB of Figure 4 and;
  • - Figure 6 is a section along CC of Figure 5.

En se référant aux dessins et plus particulièrement aux figures 3 à 5 on voit que la jonction des éléments en forme de barres 18 et des éléments ou diagonales 14 de la structure tridimensionnelle sont assemblés à l'aide d'une sphère 16 qui peut être pleine ou creuse et réalisée par exemple en acier forgé ou moulé. Ainsi qu'on le voit sur le dessin cette sphère 16 comporte des trous taraudés 20 pour la fixation de l'ensemble des éléments convergents vers cette sphère.Referring to the drawings and more particularly to Figures 3 to 5 we see that the junction of the elements in the form of bars 18 and the elements or diagonals 14 of the three-dimensional structure are assembled using a sphere 16 which can be full or hollow and made for example of forged or cast steel. As can be seen in the drawing, this sphere 16 has tapped holes 20 for fixing all of the converging elements to this sphere.

Au droit de chaque trou taraudé tel que 20 la sphère 16 comporte un méplat 22 réalisé par exemple par usinage afin d'obtenir un appui parfait avec l'élément ou barre tel que 18. Chaque sphère 16 comporte donc autant de trous taraudés 20 et de méplats 22 que d'éléments ou barres 18 convergents vers la sphère. L'axe des trous ou épures 24 est toujours dirigé vers le centre de la sphère.In line with each tapped hole such as 20, the sphere 16 has a flat 22 produced for example by machining in order to obtain perfect support with the element or bar such as 18. Each sphere 16 therefore has as many tapped holes 20 and flats 22 that of elements or bars 18 converging towards the sphere. The axis of the holes or diagrams 24 is always directed towards the center of the sphere.

En fonction de la géométrie des structures à assembler, on détermine pour chaque réalisation les angles donnant la position des trous taraudés sur la sphère. Chaque élément ou barre 18 est constitué par exemple d'un profil creux, rond, notamment en acier sur lequel est soudé en atelier, à chaque extrémité, un embout tronconique 26 par exemple en acier forgé. Cet embout 26 comporte un évidement 28 et un trou 30 qui permettent lors du montage de l'élément ou barre 18 d'introduire et de serrer sur la sphère 16 à l'aide d'une clé coudée une vis à tête cylindrique 32, par exemple à six pans creux.Depending on the geometry of the structures to be assembled, the angles giving the position of the tapped holes on the sphere are determined for each embodiment. Each element or bar 18 consists for example of a hollow profile, round, in particular in steel on which is welded in the workshop, at each end, a frustoconical end piece 26, for example in forged steel. This endpiece 26 has a recess 28 and a hole 30 which allow during the assembly of the element or bar 18 to introduce and tighten on the sphere 16 with the aid of an angled key a cylindrical head screw 32, by example with hexagon socket.

Du côté du profil l'embout 26 comporte un chanfrein 34 permettant de réaliser dans de bonnes conditions un cordon de soudure avec celui-ci.On the side of the profile, the end piece 26 has a chamfer 34 making it possible to produce a weld bead therewith in good conditions.

L'embout 26 peut encore comporter, dans le cas où les structures sont galvanisées par trempage à chaud, un trou 36, du côté du profil de manière à permettre l'évacuation de l'air lors du trempage de l'élément ou barre dans le bain de zinc.The end piece 26 may also include, in the case where the structures are galvanized by hot dipping, a hole 36, on the side of the profile so as to allow the evacuation of air during the dipping of the element or bar in the zinc bath.

Un des points très importants de la présente invention réside dans l'exclusion sur les éléments ou barres de tout filetage ou taraudage ce qui permet de réaliser sans inconvénient et dans des conditions parfaites l'application de toutes les protections d'acier que peut exiger l'utilisateur par exemple un sablage ou grenaillage, décapage, galvanisation à froid ou à chaud, métallisation, électrozingage, peinture traditionnelle ou polymérisation (epoxy-­four).One of the very important points of the present invention resides in the exclusion on the elements or bars of any threading or tapping which makes it possible to carry out without disadvantage and in perfect conditions the application of all the steel protections that may require the user for example sandblasting or shot blasting, pickling, cold or hot galvanizing, metallization, electrogalvanizing, traditional painting or polymerization (epoxy-oven).

Il est certain que, sur d'autres dispositifs d'assemblage constitués de noeuds sphériques et comportant des filetages ou taraudages aux extrémités des éléments ou barres, les fabricants et monteurs se trouvent confrontés à des problèmes très importants de protection des filets lors de l'application du sablage ou de la galvanisation, de la peinture ou lors de la manutention sur le chantier, surtout lorsque celui-ci est implanté sur un terrain boueux ou sablonneux. Dans le noeud d'assemblage selon l'invention, en forme de sphère, l'inexistence de filetage ou taraudage sur les éléments ou barres à assembler constitue donc un avantage primordial permettant de donner à l'utilisateur toutes les garanties de bonne tenue dans le temps des protections appliquées.It is certain that, on other assembly devices made up of spherical nodes and comprising threads or threads at the ends of the elements or bars, the manufacturers and assemblers are faced with very important problems of protection of the threads during the application of sandblasting or galvanizing, painting or during handling on site, especially when it is located on muddy or sandy ground. In the assembly node according to the invention, in the form of a sphere, the nonexistence of threading or tapping on the elements or bars to be assembled therefore constitutes a primordial advantage making it possible to give the user all the guarantees of good behavior in the time of the protections applied.

La vis 32 normalisée du commerce à tête cylindrique et à six pans creux assemble par serrage la sphère 16 et l'élément ou barre 18. Cette vis qui est indépendante de l'élément ou barre est mise en boîte dès sa fabrication et ne peut subir en conséquence aucune détérioration due à des chocs ou à des projections de terre ou de sable jusqu'à sa mise en place définitive.The standard commercial screw 32 with a cylindrical head and a hexagon socket tightens the sphere 16 and the element or bar 18. This screw which is independent of the element or bar is boxed as soon as it is manufactured and cannot undergo consequently no deterioration due to shocks or projections of earth or sand until its final installation.

On prévoit une rondelle 38, d'épaisseur théorique, qui vient s'intercaler entre la sphère 16 et l'élément ou barre tel que 18.A washer 38, of theoretical thickness, is provided which is inserted between the sphere 16 and the element or bar such as 18.

Si pour des raisons de tolérance de fabrication, l'élément ou barre tel que 18 s'avérait trop long ou trop court, le rattrapage de jeu pourrait être alors compensé par la mise en place de rondelles d'épaisseur plus ou moins importantes.If for reasons of manufacturing tolerance, the element or bar such as 18 turns out to be too long or too short, the backlash could then be compensated for by the installation of washers of greater or lesser thickness.

Comme on le voit sur la figure 6 on peut prévoir un capot 40, de préférence en matière plastique qui vient recouvrir et fermer l'évidement 28 prévu dans chacun des embouts 26 d'une barre 18 conférant ainsi à l'assemblage un aspect fini impeccable et sans vis apparente.As can be seen in FIG. 6, it is possible to provide a cover 40, preferably of plastic material which covers and closes the recess 28 provided in each of the end pieces 26 of a bar 18, thus giving the assembly an impeccable finished appearance. and without visible screw.

Il demeure bien entendu que la présente invention n'est pas limitée à l'exemple de réalisation décrit et représenté mais qu'elle en englobe toutes les variantes. Ainsi on peut réaliser la sphère d'assemblage en tout autre matériau que l'acier, par exemple en aluminium, en acier inoxidable, en matière plastique, en bois etc...It remains to be understood that the present invention is not limited to the embodiment described and shown but that it encompasses all variants thereof. Thus, the assembly sphere can be made of any material other than steel, for example aluminum, stainless steel, plastic, wood, etc.

Outre les avantages de l'invention déjà mentionnés ci-dessus on peut citer le fait que les éléments ou barres étant interchangeables, ces derniers peuvent être facilement démontés et remplacés.In addition to the advantages of the invention already mentioned above, mention may be made of the fact that the elements or bars being interchangeable, the latter can be easily disassembled and replaced.
