Abstract
Description
L'invention se rapporte à des moyens d'assemblage pour structure tridimensionnelle et à la structure ainsi assemble. The invention relates to assembly means for a three-dimensional structure and to the structure thus assembled.
Il est connu de realiser des structures tridimensionnelles à partir de noeuds d'assemblage sur lesquels se rapportent des entretoises pouvant s'tendre dans diverses directions. It is known to produce three-dimensional structures from assembly nodes on which there are spacers which can extend in various directions.
On connaît notamment (FR-A-2.352.199) un noeud constitué par une enveloppe moulée, laquelle présente dans l'épaisseur de sa paroi des perçages taraudés répartis sur toute l'enveloppe et dans chacun desquels vient se fixer une tige filetée associee à une extrémité d'entretoise. We know in particular (FR-A-2,352,199) a knot constituted by a molded casing, which has in the thickness of its wall threaded bores distributed over the entire casing and in each of which is fixed a threaded rod associated with a spacer end.
Ce type de noeud obtenu par moulage et usinage nécessite un matériel de production couteux. This type of knot obtained by molding and machining requires expensive production equipment.
On connaît aussi, un noeud constitué de deux demi-coquilles obtenues par matriçage et rapportées par soudage sur un diaphragme équatorial de faible épaisseur de manière à reconstituer une sphère. There is also known a knot consisting of two half-shells obtained by stamping and added by welding on an equatorial diaphragm of small thickness so as to reconstitute a sphere.
Si elle est moins croûteuse, avec cette forme de réalisation, il est toutefois impossible de rapporter des entretoises dans la zone du diaphragme. If it is less crusty, with this embodiment, it is however impossible to add spacers in the region of the diaphragm.
Un résultat que l'invention vise à obtenir est de proposer un moyen d'assemblage facile à réaliser et ne présentant pas les défauts precédenent cites. One result which the invention aims to obtain is to propose an assembly means which is easy to produce and which does not have the above-mentioned defects.
A cet effet, elle a pour objet des moyens d'assemblage caractérisés en ce que le noeud est constitué par
- au moins une demi-coquille de forme sensiblement hémisphérique et,
- une rondelle dont l'épaisseur est au moins suffisante pour pouvoir présenter des perçages radiaux sans pour autant en diminuer excessivement la résistance et, sur au moins l'une des faces de laquelle rondelle, est solidarisée par tout moyen connu, tel par exemple une soudure, une demi-coquille du type précité de sorte que le noeud realise alors sensiblement au moins une demi-sphère de diamètre semblable à celui de la rondelle.To this end, it relates to assembly means characterized in that the node is constituted by
- at least one half-shell of substantially hemispherical shape and,
- A washer whose thickness is at least sufficient to be able to present radial holes without excessively reducing its resistance and, on at least one of the faces of which washer, is secured by any known means, such as for example a welding, a half-shell of the aforementioned type so that the knot then realizes substantially at least a half-sphere of diameter similar to that of the washer.
Elle a également pour objet la structure comprenant de tels moyens d'assemblage. It also relates to the structure comprising such assembly means.
L'invention sera bien comprise à l'aide de la description ci-aprés faite à titre d'exemple non limitatif qui représente schématiquement
- figure 1 : en vue partielle une structure tridimensionnelle,
- figure 2 : le noeud vu en coupe,
- figure 3 : une coupe selon III-III de la figure 2,
- figure 4 : l'extrémité d'une entretoise vue en coupe,
- figure 5 : une coupe V-V de la figure 4.The invention will be better understood with the aid of the description below made by way of nonlimiting example which schematically represents
- Figure 1: in partial view a three-dimensional structure,
- Figure 2: the knot seen in section,
- Figure 3: a section on III-III of Figure 2,
- Figure 4: the end of a spacer seen in section,
- Figure 5: a section VV of Figure 4.
En se reportant aux dessins, on voit que la structure tridimensionelle I comprend des noeuds de liaison 2 et des entretoises 3 reliant ces noeuds et s'tendant dans l'espace suivant des directions 4 definies en fonction de la forme de la structure à réaliser. Referring to the drawings, it can be seen that the three-dimensional structure I comprises connecting nodes 2 and spacers 3 connecting these nodes and extending in space in directions 4 defined according to the shape of the structure to be produced.
Chaque noeud 2 comporte une pluralité de moyens d'ancrage 5 sur chacun desquels, au moyen d'un dispositif de jonction 6, vient se fixer l'extrémité 7 d'une entretoise. Each node 2 comprises a plurality of anchoring means 5 on each of which, by means of a joining device 6, is fixed the end 7 of a spacer.
Selon l'invention, le noeud 2 est constitué par
- au moins une demi-coquille 8 de forme sensiblement hémisphérique et,
- une rondelle 9 dont l'épaisseur est au moins suffisante pour pouvoir présenter des perçages 10 radiaux sans pour autant en diminuer excessivement la résistance et sur au moins l'une des faces 11, 12 de laquelle rondelle est solidarisée par tout moyen connu tel par exemple une soudure, une demi-coquille 8 du type précité de sorte que le noeud réalise alors sensiblement au moins une demi-sphère de diamètre d semblable à celui D de la rondelle.According to the invention, node 2 consists of
at least one half-shell 8 of substantially hemispherical shape and,
a washer 9 the thickness of which is at least sufficient to be able to present radial holes 10 without excessively reducing the resistance thereof and on at least one of the faces 11, 12 of which the washer is secured by any known means such as example a weld, a half-shell 8 of the aforementioned type so that the knot then produces substantially at least one half-sphere of diameter d similar to that D of the washer.
Dans une forme de réalisation préférée, on associe une demi-coquille 8 à chacune des faces de la rondelle 9 pour réaliser sensiblement une sphère complet. In a preferred embodiment, a half-shell 8 is associated with each of the faces of the washer 9 to produce substantially a complete sphere.
L'utilisation d'une rondelle 9 d'epaisseur importante permet de realiser dans le plan équatorial de la sphère passant par la rondelle des perçages taraudés 10 de dimensions importantes sans pour autant réduire la longueur du cordon de soudure. The use of a washer 9 of large thickness allows to realize in the equatorial plane of the sphere passing through the washer tapped holes 10 of large dimensions without reducing the length of the weld bead.
Par exemple, pour un noeud sensiblement sphérique ayant un diamètre égal à soixante trois millimètres, on choisira une rondelle de quatorze millimètres d'épaisseur dans laquelle il sera possible de realiser des perçages et taraudages pour vis de huit millimètres de diamètre. For example, for a substantially spherical knot having a diameter equal to sixty three millimeters, a washer of fourteen millimeters thick will be chosen in which it will be possible to make holes and tappings for screws of eight millimeters in diameter.
Classiquement, pour permettre la fixation sur la demi-coquille par des vis associées à chaque entretoise, celle-ci présente, repartis suivant des directions préétablies, des perçages radiaux concentriquement à chacun desquels est fixé un écrou 13, par exemple par sertissage, afin de l'immobiliser entre deux collerettes 14a, 14b. Conventionally, to allow attachment to the half-shell by screws associated with each spacer, the latter has, distributed in predetermined directions, radial holes concentrically to each of which is fixed a nut 13, for example by crimping, in order to immobilize it between two flanges 14a, 14b.
Les écrous 13 peuvent former sur la face externe 15 de la demi-coquille 8 une certaine surépaisseur e. The nuts 13 can form on the external face 15 of the half-shell 8 a certain extra thickness e.
La rondelle 9 a un diamètre D égal au diamètre d de la demi-sphere reconstituée majorée de deux fois cette surépaisseur e due à l'écrou. The washer 9 has a diameter D equal to the diameter d of the reconstituted half-sphere increased by twice this extra thickness e due to the nut.
Ainsi, lors du serrage des entretoises sur le noeud d'assemblage, les surfaces frontales des extrémites des entretoises peuvent prendre appui sur des surfaces équidistantes du centre 0 de la demi-sphère reconstituée. Thus, during the tightening of the spacers on the assembly node, the front surfaces of the extremities of the spacers can bear on equidistant surfaces from the center 0 of the reconstituted hemisphere.
Dans une forme de réalisation, au moins la face de la rondelle sur laquelle s'appuie la demi-coquille presente un épaulement 16 de centrage de la demi-coquille, par exemple, obtenu par reduction locale de l'épaisseur de la rondelle. In one embodiment, at least the face of the washer on which the half-shell rests has a shoulder 16 for centering the half-shell, for example, obtained by local reduction of the thickness of the washer.
Le dispositif de jonction 6 présente un embout 6, par exemple de forme tronconique, rapporté sur l'entretoise 3 et traverse axialement par un perçage 17, à l'arrière duquel est constitué un épaulement 19 sur lequel prendra appui, lors du serrage, la tête 20 d'une vis 21, lequel épaulement 19 pourra être constitué par la face interne de l'embout ou par un lamage ou alésage 18 centré sur l'axe du perçage qu'il prolonge. The joining device 6 has a tip 6, for example of frustoconical shape, attached to the spacer 3 and passes axially through a bore 17, at the rear of which is formed a shoulder 19 on which will bear, during tightening, the head 20 of a screw 21, which shoulder 19 may be constituted by the internal face of the end piece or by a countersink or bore 18 centered on the axis of the bore that it extends.
Pour permettre la manoeuvre de la vis de serrage, selon l'invention
- entre la tête 20 et l'extrémité filetée 22 destinee à être engagee dans l'un des écrous du noeud 2, la vis présente un corps 23 dont la longueur est au moins suffisante pour traverser le perçage 17 de l'embout 6 puis une piece de manoeuvre 24 par exemple semblable extérieurerient à un écrou, laquelle piece 24 s'intercale alors entre la surface frontale 25 de l'embout et l'écrou 13 du noeud,
- la piece de manoeuvre 24 et, dans son tronçon 26 dit de manoeuvre, le corps 23 ont des formes complémentaires autres que de revolution autour de l'axe de la vis de sorte que la pièce de manoeuvre 24 est immobilisée en rotation mais libre en translation sur le dit tronçon de manoeuvre du corps de la vis,
- le corps 23 de la vis et la pièce de manoeuvre 24 comprennnent des moyens complémentaires 27, 28 limitant la translation de la pièce de manoeuvre sur le corps de la vis comme, par exemple, une tige 27 traversant la paroi de la pièce de manoeuvre et dont l'extrémité interne coopere avec une rainure 28 parallèle à l'axe longitudinal de la vis. To allow operation of the clamping screw according to the invention
- Between the head 20 and the threaded end 22 intended to be engaged in one of the nuts of the node 2, the screw has a body 23 whose length is at least sufficient to pass through the bore 17 of the end piece 6 and then a operating part 24, for example, similar to the outside of a nut, which part 24 is then inserted between the front surface 25 of the end piece and the nut 13 of the knot,
the maneuvering piece 24 and, in its so-called maneuvering section 26, the body 23 have complementary shapes other than of rotation about the axis of the screw so that the maneuvering piece 24 is immobilized in rotation but free in translation on said maneuvering section of the body of the screw,
- The body 23 of the screw and the operating part 24 include complementary means 27, 28 limiting the translation of the operating part on the body of the screw such as, for example, a rod 27 passing through the wall of the operating part and the internal end of which cooperates with a groove 28 parallel to the longitudinal axis of the screw.
