L'invention est relative à un noeud d'assemblage, pour structure spatiale, constitué par des éléments plats réunis entre eux, en particulier par soudage.The invention relates to an assembly node, for spatial structure, consisting of flat elements joined together, in particular by welding.

On sait que les structuresspatialesoffrent une grande résistance et permettent de réaliser les formes les plus diverses avec de très grandes portées.We know that spatial structures offer great resistance and allow the most diverse shapes to be produced with very large spans.

L'invention concerne plus particulièrement, parce que c'est dans ce cas que son application semble devoir présenter le plus d'intérêt, mais non exclusivement, les noeuds d'assemblages pour structuresspa- tiales utilisées pour les constructions de bâtiments.The invention relates more particularly, because it is in this case that its application seems to present the most interest, but not exclusively, the knots of assemblies for space structures used for the constructions of buildings.

Un des problèmes délicats dans la réalisation de telles structures réside dans l'assemblage des divers éléments de la structure qui convergent, suivant plusieurs directions dans l'espace, vers un point de fixation, cet assemblage étant généralement réalisé à l'aide d'un noeud d'assemblage.One of the delicate problems in the realization of such structures resides in the assembly of the various elements of the structure which converge, in several directions in space, towards a fixing point, this assembly being generally carried out using a assembly node.

L'invention a pour but, surtout/de rendre ce noeud d'assemblage tel qu'il réponde mieux que jusqu'à présent aux diverses exigences de la pratique et notamment tel qu'il soit d'une construction simple et économique tout en assurant de bonnes conditions de travail mécanique pour la matière constituant le noeud d'assemblage.The object of the invention is, above all / to make this assembly node such that it better meets the various requirements of practice than hitherto, and in particular such that it is of a simple and economical construction while ensuring good mechanical working conditions for the material constituting the assembly node.

Selon l'invention, un noeud d'assemblage pour structure spatiale, constitué par des éléments plats, est caractérisé par le fait qu'il comporte au moins un élément plat ayant une fente située sensiblement à mi-largeur de cet élément plat de manière à passer par le point de concours des différentes forces, cette fente étant orientée suivant la direction longitudinale et qu'au moins un autre élément plat notamment formé par une plaque, est engagé dans cette fente et la traverse, cette plaque comportant des moyens, notamment formés par des trous, pour permettre d'attacher des barres, dont l'axe serait situé dans le plan de la plaque, de part et d'autre dudit élément plat, les différents éléments du noeud étant réunis entre eux, notamment le long des bords de la fente.According to the invention, an assembly node for a spatial structure, consisting of flat elements, is characterized in that it comprises at least one flat element having a slot located substantially at the mid-width of this flat element so as to pass through the point of competition of the different forces, this slot being oriented in the longitudinal direction and that at least one other flat element in particular formed by a plate, is engaged in this slot and crosses it, this plate comprising means, in particular formed by holes, to allow the attachment of bars, the axis of which would be located in the plane of the plate, on either side of said flat element, the various elements of the knot being joined together, in particular along the edges of the slot.

Le noeud d'assemblage peut comprendre deux éléments plats formant un dièdre, réunis suivant l'arête de ce dièdre ; au moins un des éléments plats du dièdre comprend une fente dans laquelle est engagé un autre élément plat, notamment formé par une plaque.The assembly node may include two flat elements forming a dihedral, joined along the edge of this dihedral; at least one of the flat elements of the dihedral comprises a slot in which is engaged another flat element, in particular formed by a plate.

Avantageusement, chaque élément plat du dièdre peut comprendre à mi-largeur, une fente, ces deux fentes se rejoignant sur l'arête du dièdre pour former une seule fente située dans un plan perpendiculaire à l'arête du dièdre, à mi-longueur de cette arête, ladite fente étant fermée à ses deux extrémités, ce noeud étant combiné avec une plaque ou autre élément plat engagé dans ladite fente du dièdre.Advantageously, each flat element of the dihedron may comprise at mid-width, a slot, these two slots joining on the edge of the dihedron to form a single slot situated in a plane perpendicular to the edge of the dihedron, at mid-length. this edge, said slot being closed at its two ends, this node being combined with a plate or other flat element engaged in said slot of the dihedral.

Un noeud d'assemblage complexe peut être formé par plusieurs noeuds d'assemblage élémentaires combinés avec une plaque ou élément plat engagée dans les fentes des noeuds d'assemblages élémentaires réunis de manière à former le noeud complexe.A complex assembly node can be formed by several elementary assembly nodes combined with a plate or flat element engaged in the slots of the elementary assembly nodes joined together so as to form the complex node.

Les noeuds d'assemblages élémentaires sont de préférence montés sur la plaque et assemblés de manière que les faces voisines de dièdres différents soient légèrement écartées pour laisser entre elles un espace propre à recevoir l'extrémité de la barre destinée à être accrochée sur le noeud.The nodes of elementary assemblies are preferably mounted on the plate and assembled in such a way that the neighboring faces of different dihedrons are slightly apart to leave between them a space suitable for receiving the end of the bar intended to be hung on the node.

De préférence, le premier élément plat, qui comporte une fente située sensiblement à mi-largeur, s'étend, suivant le sens longitudinal de la fente, de part et d'autre du second élément plat, et comporte des moyens permettant d'accrocher des barres de chaque côté du second élément plat selon la direction longitudinale de la fente, de telle sorte que la transmission des efforts, par le premier élément plat de part et d'autre du centre du noeud soit effectué essentiellement parallèlement à la direction longitudinale de la fente, la petite dimension de la fente étant orientée transversalement à la direction de transmission des efforts.Preferably, the first flat element, which has a slit located substantially at mid-width, extends, in the longitudinal direction of the slit, on either side of the second flat element, and comprises means making it possible to hang bars on each side of the second flat element in the longitudinal direction of the slot, so that the transmission of forces, by the first flat element on either side of the center of the node is effected essentially parallel to the longitudinal direction of the slot, the small dimension of the slot being oriented transversely to the direction of transmission of the forces.

Le premier élément plat peut comporter une fente longitudinale fermée à ses deux extrémités et dont la longueur et la largeur sont suffisantes pour permettre l'introduction de l'autre élément dans cette fente.The first flat element may have a longitudinal slot closed at its two ends and whose length and width are sufficient to allow the introduction of the other element in this slot.

Selon une variante, le premier élément-plat peut être formé par deux plats élémentaires, situés dans un même plan, parallèles l'un à l'autre mais écartés d'une distance suffisante pour permettre le passage du second élément plat, c'est-à-dire au moins égale à l'épaisseur de ce second élément plat ; la fente est alors réalisée de manière continue par l'écart existant entre les deux plats élémentaires, qui peuvent être réunis à leurs extrémités longitudinales.According to a variant, the first flat element can be formed by two elementary dishes, located in the same plane, parallel to each other but spaced apart by a sufficient distance to allow the passage of the second flat element, this is ie at least equal to the thickness of this second flat element; the slit is then produced continuously by the gap existing between the two elementary plates, which can be joined at their longitudinal ends.

Avantageusement, le second élément plat est identique au premier ; en particulier, le second élément plat comporte, sensiblement à mi-largeur, une fente longitudinale fermée à ses extrémités, la longueur de cette fente étant au moins égale à la largeur de l'élément plat, tandis que la largeur de la fente est sensiblement égale à l'épaisseur dudit élément plat ; dans ce cas, une ou plusieurs clés sont prévues pour être engagées dans les parties de la fente du second élément plat qui débordent de part et d'autre du premier élément plat, ces clés étant destinées à assurer le verrouillage de l'ensemble et étant situées dans des plans sensiblement orthogonaux aux arêtes des dièdres formés par le premier et le second élément plat.Advantageously, the second flat element is identical to the first; in particular, the second flat element comprises, substantially at mid-width, a longitudinal slit closed at its ends, the length of this slit being at least equal to the width of the flat element, while the width of the slit is substantially equal to the thickness of said flat element; in this case, one or more keys are provided to be engaged in the parts of the slot of the second flat element which project on either side of the first flat element, these keys being intended to ensure the locking of the assembly and being located in planes substantially orthogonal to the edges of the dihedrons formed by the first and second flat elements.

Les clés de verrouillage peuvent comporter des parties, notamment inclinées, munies de moyen d'accrochage pour des barres diagonales.The locking keys may include parts, in particular inclined, provided with hooking means for diagonal bars.

La largeur du second élément plat est orientée parallèlement à la longueur du premier élément plat.The width of the second flat element is oriented parallel to the length of the first flat element.

Le premier et le second éléments plats peuvent être orthogonaux.The first and second flat elements can be orthogonal.

Des éléments plats supplémentaires munis de moyens d'accrochage et ayant des inclinaisons appropriées, peuvent être réunis aux premier et second éléments plats pour permettre l'accrochage de barres diagonales.Additional flat elements provided with attachment means and having suitable inclinations, can be joined to the first and second flat elements to allow the attachment of diagonal bars.

Chaque élément plat peut être doublé par un autre élément plat écarté de lui suivant une direction orthogonale à son plan, les deux éléments plats étant parallèles et déterminant entre eux un espace propre à recevoir l'extrémité d'une barre de la structure ; on assure ainsi un accrochage de la barre exactement le long d'une direction passant par le centre du noeud, ce qui évite un décalage de la fixation de la barre par rapport à cette direction.Each flat element can be doubled by another flat element spaced from it in a direction orthogonal to its plane, the two flat elements being parallel and determining between them a space suitable for receiving the end of a bar of the structure; this ensures a hooking of the bar exactly along a direction passing through the center of the knot, which avoids a shift in the fixing of the bar relative to this direction.

L'invention concerne également les structures spatiales équipées de tels noeuds d'assemblage.The invention also relates to space structures equipped with such assembly nodes.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en certaines autres dispositions dont il sera plus explicitement question ci-après à propos de modes de réalisation particuliers décrits avec référence aux dessins ci-annexés, mais qui ne sont nullement limitatifs.

  • La figure 1, de ces dessins, est une vue en perspective d'un noeud d'assemblage élémentaire conforme à l'invention.
  • La figure 2 est une vue en perspective d'une plaque destinée à être engagée dans la fente du noeud de la figure 1.
  • La figure 3 représente, en perspective, un noeud d'assemblage complexe, destiné à se trouver au sein d'une structure spatiale, formé par quatre noeuds élémentaires munis d'une fente et montés sur une plaque.
  • La figure 4 montre, schématiquement, en perspective, une variante d'un noeud d'assemblage selon l'invention, en cours de réalisation.
  • La figure 5 montre, en perspective, le noeud d'assemblage terminé correspondant à la réalisation de la figure 4.
  • La figure 6, enfin, montre une autre variante de réalisation du noeud d'assemblage en perspective.
  • En se reportant à la figure 1 des dessins, on peut voir un noeud d'assemblage élémentaire ou noeud d'assemblage d'angle désigné par la référence 1. Ce noeud est constitué par des éléments plats 2, 3 et 5. Les éléments plats 2 et 3 forment un dièdre D et sont réunis suivant l'arête4 du dièdre. Les plats 2 et 3 peuvent être formés par les branches d'un plat unique qui a été plié de manière à former le dièdre D ; selon une variante, les plats 2 et 3 peuvent être distincts l'un de l'autre et réunis suivant l'arête 4 par tout moyen approprié tel que soudage, collage.
The invention consists, apart from the arrangements set out above, of certain other arrangements which will be more explicitly discussed below in connection with particular embodiments described with reference to the attached drawings, but which are in no way limiting. .
  • Figure 1 of these drawings is a perspective view of an elementary assembly node according to the invention.
  • FIG. 2 is a perspective view of a plate intended to be engaged in the slot of the node of FIG. 1.
  • FIG. 3 represents, in perspective, a complex assembly node, intended to be located within a spatial structure, formed by four elementary nodes provided with a slot and mounted on a plate.
  • Figure 4 shows, schematically, in perspective, a variant of an assembly node according to the invention, in progress.
  • FIG. 5 shows, in perspective, the completed assembly node corresponding to the embodiment of FIG. 4.
  • Figure 6, finally, shows another alternative embodiment of the assembly node in perspective.
  • Referring to Figure 1 of the drawings, one can see an elementary assembly knot or knot angle assembly designated by the reference 1. This node consists of flat elements 2, 3 and 5. The flat elements 2 and 3 form a dihedral D and are joined along the edge4 of the dihedron. The dishes 2 and 3 can be formed by the branches of a single dish which has been folded so as to form the dihedral D; alternatively, the dishes 2 and 3 can be separate from each other and joined along the edge 4 by any suitable means such as welding, bonding.

L'autre plat 5 est sensiblement orthogonal au plan bissecteur B du dièdre D. Ce plat 5 a une extrémité 6 engagée dans le dièdre D et limitée par les droites d'intersection 7, 8 du plan moyen de ce plat 5 avec les plans des faces du dièdre D, c'est-à-dire avec les plans des faces intérieures des plats 2 et 3. L'extrémité 6 est donc limitée par deux droites 7, 8 formant un angle aigu. Le plat 5 est assemblé aux faces du dièdre le long des droites d'intersection 7, 8 par soudage, collage ou autre moyen approprié.The other plate 5 is substantially orthogonal to the bisector plane B of the dihedron D. This plate 5 has one end 6 engaged in the dihedron D and limited by the straight lines of intersection 7, 8 of the mean plane of this dish 5 with the planes of the faces of the dihedral D, that is to say with the planes of the interior faces of the dishes 2 and 3. The end 6 is therefore limited by two straight lines 7, 8 forming an acute angle. The plate 5 is assembled to the faces of the dihedral along the intersection lines 7, 8 by welding, gluing or other suitable means.

Les extrémités des branches, formées par les plats 2, 3 et 5 du noeud sont munies de moyens pour permettre l'accrochage du noeud 1 à des barres telles que 10 de la structure spatiale. Ces moyens sont généralement formés par des trous 9 ; la réunion du noeud 1 et de la barre 10 peut être assurée par une vis, traversant le trou 9 et un trou correspondant de la barre 10, et un écrou non représenté.The ends of the branches, formed by the plates 2, 3 and 5 of the node are provided with means to allow the attachment of the node 1 to bars such as 10 of the spatial structure. These means are generally formed by holes 9; the union of node 1 and bar 10 can be ensured by a screw, passing through hole 9 and a corresponding hole in bar 10, and a nut not shown.

Les lignes de fixation 4, 7 et 8 sont orientées suivant trois directions concourantes non coplanaires. Il en résulte une bonne rigidité du noeud d'assemblage.The fixing lines 4, 7 and 8 are oriented in three non-coplanar concurrent directions. This results in good rigidity of the assembly node.

Au moins un élément plat, par exemple l'élément plat 2, comporte une fente f située sensiblement à mi-largeur de cet élément plat, notamment de manière à passer par le point de concours des différentes forces agissant sur le noeud. Cette fente f est orientée suivant la direction longitudinale du plat 2. Au moins un autre élément plat 13, comme visible sur la figure 3, notamment formé par une plaque, est destiné à être engagé dans cette fente f et à la traverser ; la plaque 13 comporte des moyens, notamment formés par des trous 14, pour permettre d'attacher des barres dont l'axe serait situé dans le plan de la plaque, de part et d'autre dudit élément plat 2, les différents éléments du noeud étant réunis entre eux, notamment le long des bords de la fente f en particulier par un cordon de soudure.At least one flat element, for example the flat element 2, comprises a slot f situated substantially at the mid-width of this flat element, in particular so as to pass through the point of competition of the various forces acting on the knot. This slot f is oriented in the longitudinal direction of the plate 2. At least one other flat element 13, as visible in FIG. 3, in particular formed by a plate, is intended to be engaged in this slot f and to pass through it; the plate 13 comprises means, in particular formed by holes 14, to allow the attachment of bars whose axis would be located in the plane of the plate, on either side of said flat element 2, the various elements of the node being joined together, in particular along the edges of the slot f in particular by a weld bead.

Avantageusement, chaque élément plat 2, 3 comprend, à mi-largeur, une fente f, ces deux fentes se rejoignant sur l'arête 4 du dièdre pour former une seule fente située dans un plan perpendiculaire à l'arête 4 du dièdre, à mi-longueur de cette arête. Cette fente est fermée à ses deux extrémités e2, e3. Généralement la fente f s'étend d'une même longueur 1 dans les deux faces du dièdre D.Advantageously, each flat element 2, 3 comprises, at mid-width, a slot f, these two slots joining on the edge 4 of the dihedron to form a single slot located in a plane perpendicular to the edge 4 of the dihedron, with mid-length of this edge. This slot is closed at its two ends e2, e3. Generally the slot f extends with the same length 1 in the two faces of the dihedral D.

La plaque 13, représentée sur la figure 2, est engagée dans les deux fentes élémentaires prévues dans les plats 2 et 3, comme visible sur la figure 3.The plate 13, shown in FIG. 2, is engaged in the two elementary slots provided in the dishes 2 and 3, as visible in FIG. 3.

La plaque 13 peut avoir une forme carrée, comme représenté sur la figure 2, pour une structure bi-directionnelle.The plate 13 may have a square shape, as shown in Figure 2, for a bi-directional structure.

Toutefois, cette plaque 13 peut avoir d'autres formes, par exemple hexagonale ou triangulaire, pour une structure tridirectionnelle ou pour la réalisation d'un noeud de rive.However, this plate 13 can have other shapes, for example hexagonal or triangular, for a three-directional structure or for the production of an edge knot.

Sur la figure 2, on a représenté, en traits . mixtes, la trace moyenne des fentes f de noeud d'assemblage tel que le noeud 1 de la figure 1 qui serait engagé sur la plaque 13 ; on a représenté quatre angles droits en traits mixtes, passant près des sommets de la plaque 13 et correspondant à quatre dièdres tels que 1, figure 1, engagés sur cette plaque. On comprend que les faces telles que 2 et 3 des dièdres sont perpendiculaires au plan de la plaque 13 et sont orientées suivant les diagonales de cette plaque .In Figure 2, there is shown in lines. mixed, the average trace of the slots f of the assembly node such as the node 1 of FIG. 1 which would be engaged on the plate 13; four right angles have been shown in phantom, passing near the tops of the plate 13 and corresponding to four dihedrons such as 1, FIG. 1, engaged on this plate. It is understood that the faces such as 2 and 3 of the dihedrons are perpendicular to the plane of the plate 13 and are oriented along the diagonals of this plate.

On peut prévoir une ou plusieurs pattes telles que 15, 16 soudées sur la plaque 13 de part et d'autre de cette plaquer et admettant un même plan moyen perpendiculaire à la plaque 13 et passant par une diagonale de cette plaque. Ces pattes 15 et 16 se trouvent prises en sandwich, lors du montage des dièdres tels que l,figure 1; sur la plaque 13, entre les faces contiguës de dièdres.Ces pattes 15 et 16 sont munies de trous 17 permettant l'accrochage de barres dont l'axe est perpendiculaire au plan de la plaque 13.One or more legs such as 15, 16 can be provided welded to the plate 13 on either side of this plate and admitting the same mean plane perpendicular to the plate 13 and passing through a diagonal of this plate. These legs 15 and 16 are sandwiched, during the mounting of the dihedrons such as l, Figure 1; on the plate 13, between the contiguous faces of dihedrons. These legs 15 and 16 are provided with holes 17 allowing the attachment of bars whose axis is perpendicular to the plane of the plate 13.

Selon une variante, les pattes 15 et 16 peuvent être formées par les parties d'un seul et même plat qui traverse une fente prévue dans la plaque 13 et qui s'étend de part et d'autre de cette plaque. Ce plat peut être soudé à la plaque 13 le long des bords de la fente prévue dans ladite plaque pour le passage du plat.According to a variant, the legs 15 and 16 can be formed by the parts of a single flat which passes through a slot provided in the plate 13 and which extends on either side of this plate. This dish can be welded to the plate 13 along the edges of the slot provided in said plate for the passage of the dish.

Sur la figure 3, on peut voir le noeud complexe obtenu par la réunion de la plaque 13 de la figure 2 avec quatre noeuds d'assemblage élémentaires, comprenant, chacun,deux plats tels que 5a, 12a pour le dièdre D , situés dans un plan perpendiculaire au plan bissecteur du dièdre et s'étendant de part et d'autre du plan de la plaque 13. On a utilisé les références Da, Db, Dc, Dd, pour désigner les quatre dièdres formant les noeuds d'assemblage élémentaires montés sur la plaque 13.In Figure 3, we can see the complex knot obtained by joining the plate 13 of Figure 2 with four elementary assembly nodes, each comprising two plates such as 5a, 12a for the dihedral D, located in a plane perpendicular to the bisector plane of the dihedral and extending on either side of the plane of the plate 13. The references Da, Db, Dc, Dd have been used to designate the four dihedrons forming the elementary assembly nodes mounted on plate 13.

On note, cependant, que les plats tels que 2a, 3a sont propres à chaque dièdre.We note, however, that dishes such as 2a, 3a are specific to each dihedral.

Un espace tel que j est ménagé entre les faces telles que 3a, 2b ou 3b, 2c, etc... voisines de dièdres différents.A space such as j is provided between the faces such as 3a, 2b or 3b, 2c, etc., which are adjacent to different dihedrons.

Cet espace j permet d'introduire l'extrémité d'une barre de la structure (extrémité notamment formée par l'aile d'un té soudé à l'extrémité de la barre) entre deux faces telles que 3a, 2b, voisines de dièdres. On assure ainsi l'accrochage de la barre exactement le long d'une direction passant par le centre du noeud, ce qui réduit tout moment de flexion dû à un décalage de la fixation de la barre par rapport à ladite direction.This space j makes it possible to introduce the end of a bar of the structure (end in particular formed by the wing of a tee welded to the end of the bar) between two faces such as 3a, 2b, adjacent to dihedrons . This ensures the attachment of the bar exactly along a direction passing through the center of the knot, which reduces any bending moment due to a shift in the fixing of the bar relative to said direction.

Les différents dièdres sont réunis entre eux, notamment par soudage, à leurs sommets et/ou avec la plaque 13 ; le soudage des faces des dièdres et de cette plaque 13 le long des bords des fentes f assure un assemblage particulièrement rigide.The various dihedrons are joined together, in particular by welding, at their vertices and / or with the plate 13; the welding of the faces of the dihedrons and of this plate 13 along the edges of the slots f ensures a particularly rigid assembly.

Il serait naturellement possible de monter les dièdres sur la plaque 13 de sorte que les faces voisines soient au contact l'une de l'autre, tout au moins pour les faces dont la mise en contact n'est pas gênée par la présence d'une patte telle que 15.It would naturally be possible to mount the dihedrons on the plate 13 so that the neighboring faces are in contact with one another, at least for the faces whose contacting is not hampered by the presence of a tab such as 15.

En se reportant à la figure 4, on peut voir une variante de réalisation d'un noeud d'assemblage 101, pour structure spatiale, conforme à l'invention, en cours de préparation. Ce noeud d'assemblage est constitué par des éléments plats réunis ou destinés à être réunis entre eux lorsque le noeud est terminé.Referring to Figure 4, we can see an alternative embodiment of an assembly node 101, for spatial structure, according to the invention, in preparation. This assembly node consists of flat elements joined together or intended to be joined together when the node is finished.

Le noeud 101 comprend au moins un premier élément plat 102 qui comporte une fente f située sensiblement à mi-largeur de l'élément 102 de manière à passer par le point de concours des différentes forces qui s'exercent sur le noeud monté dans la structure spatiale. La direction longitudinale de la fente f est orientée parallèlement à la direction longitudinale L de l'élément plat 102.The node 101 comprises at least a first flat element 102 which comprises a slot f situated substantially at the mid-width of the element 102 so as to pass through the point of competition of the various forces which are exerted on the node mounted in the structure spatial. The longitudinal direction of the slot f is oriented parallel to the longitudinal direction L of the flat element 102.

Au moins un deuxième élément plat 113 est engagé dans la fente f et la traverse, ce deuxième élément plat 113 comportant des moyens, notamment formés par des trous 114, pour permettre d'attacher des barres de part et d'autre du premier élément plat' 102.At least one second flat element 113 is engaged in the slot f and crosses it, this second flat element 113 comprising means, in particular formed by holes 114, to enable bars to be attached on either side of the first flat element '102.

Le premier élément plat 102 comporte également des moyens d'attache, par exemple formés par des trous 109.The first flat element 102 also includes attachment means, for example formed by holes 109.

Les deux éléments 102, 113 sont réunis l'un à l'autre ; dans le cas où les éléments plats sont en acier, la réunion de ces éléments est avantageusement assurée par soudage le long du contour de la fente f, ce contour constituant l'arête des dièdres formés par les deux éléments 102, 113.The two elements 102, 113 are joined together; in the case where the flat elements are made of steel, the joining of these elements is advantageously ensured by welding along the contour of the slot f, this contour constituting the edge of the dihedrons formed by the two elements 102, 113.

Le premier élément plat 102 s'étend suivant la direction longitudinale L, de part et d'autre du second élément plat.The first flat element 102 extends in the longitudinal direction L, on either side of the second flat element.

Les moyens formés par les trous 109 permettent d'accrocher des barres de chaque côté du second élément plat 113, selon la direction longitudinale L de la fente, de telle sorte que la transmission des efforts, par le premier élément plat 102, de part et d'autre du centre 0 du noeud est effectuée essentiellement parallèlement à la direction longitudinale de la fente f. La petite dimension ou largeur e de la fente est orientée transversalement, pratiquement perpendiculairement, à la direction des efforts transmis par l'élément 102 dans la région du centre du noeud.The means formed by the holes 109 make it possible to hang bars on each side of the second flat element 113, in the longitudinal direction L of the slot, so that the transmission of forces, by the first flat element 102, from both on the other side of the center 0 of the node is carried out essentially parallel to the longitudinal direction of the slot f. The small dimension or width e of the slot is oriented transversely, practically perpendicular, to the direction of the forces transmitted by the element 102 in the region of the center of the node.

L'ensemble est donc tel que le premier élément plat 102 et le second élément plat 113 permettent le passage et la transmission des efforts de part et d'autre du centre 0 du noeud, suivant la direction longitudinale de chaque élément plat 102, 113, sans interruption totale de la matière de ces éléments plats.The assembly is therefore such that the first flat element 102 and the second flat element 113 allow the passage and the transmission of the forces on either side of the center 0 of the node, in the longitudinal direction of each flat element 102, 113, without total interruption of the material of these flat elements.

Les éléments plats 102, 113 représentés sur les fig. 4 et 5 ont une forme rectangulaire allongée. Les trous 109 sont situés aux extrémités longitudinales de l'élément 102 et sont disposés de manière à assurer l'accrochage de barres dont la direction moyenne est dans le prolongement de la direction longitudinale moyenne de la fente f, dans le plan de l'élément 102.The flat elements 102, 113 shown in FIGS. 4 and 5 have an elongated rectangular shape. The holes 109 are located at the longitudinal ends of the element 102 and are arranged so as to ensure the attachment of bars whose mean direction is in the extension of the mean longitudinal direction of the slot f, in the plane of the element 102.

Les trous 109 pourraient être disposés autrement, par exemple de manière à assurer l'accrochage de barres dont les directions moyennes, situées dans le plan de l'élément, sont inclinées, par exemple de 45°, de part et d'autre de la direction longitudinale L de la fente. Il convient, toutefois, que la résultante des efforts exercés sur chaque extrémité longitudinale de l'élément 102 (de part et d'autre de l'élément 113) soit orientée suivant, ou sensiblement suivant, la direction longitudinale de la fente f.The holes 109 could be arranged otherwise, for example so as to ensure the attachment of bars whose mean directions, located in the plane of the element, are inclined, for example by 45 °, on either side of the longitudinal direction L of the slot. It should, however, that the result of the forces exerted on each longitudinal end of the element 102 (on either side of the element 113) be oriented along, or substantially along, the longitudinal direction of the slot f.

Ces remarques peuvent également s'appliquer à l'élément 113 dont les extrémités pourraient comporter un élargissement formé, par exemple, par des oreilles, pour l'accrochage de barres suivant plusieurs directions dans le plan de l'élément 113.These remarks can also apply to element 113, the ends of which could include a widening formed, for example, by ears, for the attachment of bars in several directions in the plane of element 113.

On a schématiquement représenté par des flèches, sur la figure 4, les efforts F1 et F2 qui s'exercent aux extrémités de l'élément plat 102 et les efforts F3, F4 qui s'exercent aux extrémités de l'élément plat 113. Ces efforts sont parallèles ou sensiblement parallèles aux directions longitudinales des éléments plats correspondants.There is diagrammatically represented by arrows, in FIG. 4, the forces F1 and F2 which are exerted at the ends of the flat element 102 and the forces F3, F4 which are exerted at the ends of the flat element 113. These forces are parallel or substantially parallel to the longitudinal directions of the corresponding flat elements.

On voit immédiatement que dans la région centrale du noeud ce sont les bandes continues de matière, telles que bl, b2 pour l'élément plat 102, qui assurent la transmission principale des efforts. Les liaisons, notamment les soudures, entre les éléments plats102, 113 n'interviennent pratiquement pas dans la transmission de ces efforts.We can immediately see that in the central region of the knot it is the continuous strips of material, such as bl, b2 for the flat element 102, which ensure the main transmission of forces. The connections, in particular the welds, between the flat elements 102, 113 practically do not intervene in the transmission of these forces.

La fente longitudinale f du premier élément plat 102 peut être fermée à ses deux extrémités longitudinales comme représenté sur la figure 4. La largeur de cette fente f est égale ou légèrement supérieure à l'épaisseur du second élément plat 113 pour permettre le passage de cet élément plat dans ladite fente f.The longitudinal slot f of the first flat element 102 can be closed at its two longitudinal ends as shown in FIG. 4. The width of this slot f is equal or slightly greater than the thickness of the second flat element 113 to allow the passage of this flat element in said slot f.

Comme visible sur la figure 4, la direction longitudinale de l'élément plat 113 est orientée transversalement par rapport à la direction longitudinale L du premier élément plat 102.As can be seen in FIG. 4, the longitudinal direction of the flat element 113 is oriented transversely with respect to the longitudinal direction L of the first flat element 102.

La largeur du second élément plat 113 est orientée parallèlement ou sensiblement parallèlement à la direction longitudinale L du premier élément plat 102.The width of the second flat element 113 is oriented parallel or substantially parallel to the longitudinal direction L of the first flat element 102.

Les deux éléments plat 102, 113 peuvent être orthogonaux, comme représenté sur la figure 4 et déterminer par leur intersection quatre dièdres droits. Toutefois, l'angle formé entre les plans des éléments plat 102 et 113 peut être différent de 90°.The two flat elements 102, 113 can be orthogonal, as shown in FIG. 4 and determine by their intersection four straight dihedrons. However, the angle formed between the planes of the flat elements 102 and 113 can be different from 90 °.

La fente f peut être réalisée directement dans un élément plat , dans sa partie médiane, à mi-longueur.The slot f can be made directly in a flat element, in its middle part, at mid-length.

Selon une autre possibilité, l'élément plat 102 pourrait être réalisé à l'aide de deux plats, situés dans le même plan, et placés en appui l'un contre l'autre suivant un côté longitudinal X1-X1 , ces deux plats seraient ensuite soudés l'un à l'autre suivant ce côté X1-X1 qui formerait alors l'axe correspondant à la fibre neutre. Dans ce cas, avant assemblage des deux plats par soudage suivant la ligne X1-X1, on réaliserait sur les bords longitudinaux de chacun des plats destinés à venir l'un contre l'autre, une ouverture s'ouvrant sur ce bord longitudinal et ayant une largeur égale à e/2, c'est-à-dire à la moitié de la largeur de la fente f ; lors de l'assemblage des deux plats, ces deux ouvertures viendraient en regard l'une de l'autre, symétriquement par rapport à la ligne X1-X1 de telle sorte que la fente f serait ainsi reconstituée après assemblage des deux plats.According to another possibility, the flat element 102 could be produced using two dishes, located in the same plane, and placed in abutment one against the other along a longitudinal side X1-X1, these two dishes would be then welded to each other along this side X1-X1 which would then form the axis corresponding to the neutral fiber. In this case, before assembling the two dishes by welding along the line X1-X1, there would be produced on the longitudinal edges of each of the dishes intended to come against one another, an opening opening on this longitudinal edge and having a width equal to e / 2, that is to say half the width of the slot f; during the assembly of the two dishes, these two openings would come opposite one another, symmetrically with respect to the line X1-X1 so that the slot f would thus be reconstituted after assembly of the two dishes.

Selon une variante, le premier élément plat 102 peut être formé par deux plats élémentaires, situés dans un même plan, parallèles l'un à l'autre, mais écartés d'une distance e suffisante pour permettre le passage du second élément plat 113 entre ces deux plats élémentaires. La fente ou passage du plat 102 serait alors réalisée de manière continue, sensiblement suivant toute la longueur des deux plats élémentaires qui pourraient être réunis l'un à l'autre à leurs deux extrémités longitudinales.According to a variant, the first flat element 102 can be formed by two elementary dishes, located in the same plane, parallel to each other, but spaced apart by a distance e sufficient to allow the passage of the second flat element 113 between these two elementary dishes. The slot or passage of the dish 102 would then be carried out continuously, substantially along the entire length of the two elementary dishes which could be joined to one another at their two longitudinal ends.

Avantageusement, le second élément plat 113 comporte également une fente longitudinale f2 située à mi-largeur de cet élément. De préférence, la fente f2 est identique à la fente f et l'élément 113 est identique à l'élément plat 102. Dans la représentation des figures 1 et 2, la fente f2, identique à la fente f, a une longueur au moins égale à la largeur de l'élément plat, tandis que la largeur de la fente est au moins égale à l'épaisseur dudit élément plat.Advantageously, the second flat element 113 also includes a longitudinal slot f2 located at the half-width of this element. Preferably, the slot f2 is identical to the slot f and the element 113 is identical to the flat element 102. In the representation of Figures 1 and 2, the slot f2, identical to the slot f, has a length at least equal to the width of the flat element, while the width of the slot is at least equal to the thickness of said flat element.

Deux clés C1, C2 (fig. 4 et 5) sont alors prévues pour être engagées dans les parties de la fente f2 qui débordent de part et d'autre du premier élément plat 102 ; ces clés sont destinées à assurer le verrouillage de l'ensemble et sont situées dans un plan orthogonal à l'arête des dièdres formés par les éléments 102 et 113. Comme visible d'après les figures 4 et 5, les clés C1, C2 traversent complètement la fente f2 et sont formées, par exemple, par un élément rectangulaire dont un grand côté vient s'appliquer contre l'élément 102, suivant la largeur de cet élément. Les clés C7. et C2 sont assemblées aux éléments plats 102, 113, notamment par soudage, ou par effet de coin, ou autre, suivant les lignes des arêtes des différents dièdres ou trièdres formés par des éléments plats imbriqués les uns dans les autres.Two keys C1, C2 (fig. 4 and 5) are then provided to be engaged in the parts of the slot f2 which project on either side of the first flat element 102; these keys are intended to ensure the locking of the assembly and are located in a plane orthogonal to the edge of the dihedrons formed by the elements 102 and 113. As visible from FIGS. 4 and 5, the keys C1, C2 pass through completely the slot f2 and are formed, for example, by a rectangular element of which a large side is applied against the element 102, along the width of this element. The keys C7. and C2 are assembled to the flat elements 102, 113, in particular by welding, or by wedge effect, or the like, along the lines of the edges of the various dihedrons or trihedra formed by flat elements nested one inside the other.

Il est à noter que chaque clé de verrouillage C1, C2 peut comporter une partie, notamment une partie-telle que g2, inclinée par rapport au plan de la clé orthogonal à l'arête du dièdre formé par les éléments 102, 113, et munie de moyens d'accrochage (trou 109a) pour des barres diagonales.It should be noted that each locking key C1, C2 may comprise a part, in particular a part such as g2, inclined relative to the plane of the key orthogonal to the edge of the dihedron formed by the elements 102, 113, and provided hooking means (hole 109a) for diagonal bars.

Des éléments plats supplémentaires tels que 105 (fig.5 ) munis de moyens d'accrochage tels que les trous 109b, et ayant des inclinaisons appropriées sont prévus pour permettre l'accrochage de plusieurs barres diagonales.Additional flat elements such as 105 (fig.5) provided with attachment means such as holes 109b, and having suitable inclinations are provided to allow the attachment of several diagonal bars.

Ces éléments plats 105 ont leur plan orthogonal ou sensiblement orthogonal au plan bissecteur d'un dièdre, notamment d'un dièdre formé par une clé telle que la clé C1 et l'élément plat 102. Dans la représentation de la figure 5, l'élément plat supplémentaire 105 est engagé dans un dièdre situé au-dessous de l'élément plat 113.L'extrémité du plat 105 est limitée par les droites d'intersection entre ce plat et les faces du dièdre formé par la clé C1 et l'élément plat 102 ; l'extrémité du plat 105 épouse la surface intérieure du dièdre et est assemblée aux faces de ce dièdre, le long des droites d'intersection, notamment par soudage.These flat elements 105 have their plane orthogonal or substantially orthogonal to the bisector plane of a dihedron, in particular of a dihedron formed by a key such as the key C1 and the flat element 102. In the representation of FIG. 5, the additional flat element 105 is engaged in a dihedral situated below the flat element 113. The end of the flat 105 is limited by the straight lines of intersection between this flat and the faces of the dihedral formed by the key C1 and the flat element 102; the end of the dish 105 follows the inside surface of the dihedral and is assembled to the faces of this dihedral, along the lines of intersection, in particular by welding.

D'autres éléments plats supplémentaires, tels que 105a, 105b, 105c, semblables à l'élément 105, peuvent être prévus dans les autres dièdres.Other additional flat elements, such as 105a, 105b, 105c, similar to element 105, can be provided in the other dihedrons.

Comme visible sur la figure 6, chaque élément plat peut être doublé par un autre élément plat écarté de lui suivant une direction orthogonale à son plan.As shown in Figure 6, each flat element can be doubled by another flat element spaced from it in a direction orthogonal to its plane.

Ainsi, deux éléments plats 102a, 102b sont prévus ; ces deux éléments plats sont parallèles et déterminent entre eux un espace j propre à recevoir l'extrémité 110e d'une barre 110 de la structure spatiale ; l'extrémité 110e comporte des trous propres à venir en face des trous 109 des éléments 102a, 102b pour permettre l'accrochage par tous moyens appropriés tels que boulons, clavettes. La barre 110 peut être une barre cylindrique dont l'extrémité 110e a été aplatie pour s'engager dans l'espace j. On assure, ainsi, un accrochage de la barre exactement le long d'une direction passant par le centre du noeud, en évitant un décalage de la fixation de la barre par rapport à cette direction.Thus, two flat elements 102a, 102b are provided; these two flat elements are parallel and determine between them a space j suitable for receiving the end 110e of a bar 110 of the spatial structure; the end 110e has clean holes to come in front of the holes 109 of the elements 102a, 102b to allow hooking by any appropriate means such as bolts, keys. The bar 110 can be a cylindrical bar whose end 110e has been flattened to engage in the space j. We thus ensure a hooking of the bar exactly along a direction passing through the center of the node, avoiding a shift in the attachment of the bar relative to this direction.

Le deuxième élément plat est également doublé et formé par l'ensemble des éléments 113a, 113b parallèles et écartés l'un de l'autre pour déterminer également un espace j.The second flat element is also doubled and formed by all of the elements 113a, 113b parallel and spaced from one another to also determine a space j.

Ces deux éléments 113a, 113b, traversent les deux premiers éléments 102a, 102b qui sont chacun munis, à mi-largeur, d'une fente longitudinale f, fermée à ses deux extrémités longitudinales. La largeur de la fente f de la figure 6 est suffisante pour permettre le passage des éléments 113a, 113b écartés l'un de l'autre ; les divers éléments 102a, 102b, 113a, 113b sont assemblés le long des arêtes des dièdres qu'ils déterminent.These two elements 113a, 113b, pass through the first two elements 102a, 102b which are each provided, at mid-width, with a longitudinal slot f, closed at its two longitudinal ends. The width of the slot f in FIG. 6 is sufficient to allow the passage of the elements 113a, 113b separated from one another; the various elements 102a, 102b, 113a, 113b are assembled along the edges of the dihedrons that they determine.

Il est à noter que les éléments 113a; 113b de la figure 6 sont dépourvus de fentes longitudinales ; dans la réalisation de cette figure 6, cette fente ne serait pas utilisée.It should be noted that the elements 113a; 113b of Figure 6 are devoid of longitudinal slots; in the embodiment of this figure 6, this slot would not be used.

Le noeud d'assemblage est complété par des éléments plats supplémentaires permettant l'accrochage de barres diagonales.The assembly node is completed by additional flat elements allowing the attachment of diagonal bars.

Ces éléments plats supplémentaires sont également doublés ; ils forment deux groupes symétriques par rapport au plan parallèle aux éléments 102a, 102b et équidistant de ces éléments.These additional flat elements are also doubled; they form two groups symmetrical with respect to the plane parallel to the elements 102a, 102b and equidistant from these elements.

Le groupe des éléments plats supplémentaires, situé sur la droite, selon la figure 6 , par rapport au plan équidistant des éléments 102a, 102b, comprend deux éléments plats extérieurs 120, 121 et un élément plat 122 plié de manière à former un dièdre.The group of additional flat elements, located on the right, according to FIG. 6, with respect to the equidistant plane of the elements 102a, 102b, comprises two external flat elements 120, 121 and a flat element 122 folded so as to form a dihedron.

Les éléments plats 120, 121, sont orthogonaux aux plans des éléments 113a, 113b, et forment un angle, par exemple de 45°, avec l'élément plat 102a. Les éléments plats 120, 121, s'étendent de part et d'autre des plats 113a, 113b ; chaque élément plat 120, 121, comporte une fente telle que f3 qui enserre les deux éléments 113a, 113b, comme visible sur la figure 6. Cette fente f3 est fermée vers l'extérieur, mais débouche sur les bords de l'élément 120 vers le centre du noeud. Il en est de même pour l'élément 121.,The flat elements 120, 121 are orthogonal to the planes of the elements 113a, 113b, and form an angle, for example of 45 °, with the flat element 102a. The flat elements 120, 121 extend on either side of the dishes 113a, 113b; each flat element 120, 121, has a slot such as f3 which encloses the two elements 113a, 113b, as visible in FIG. 6. This slot f3 is closed towards the outside, but opens at the edges from element 120 to the center of the node. The same is true for element 121.,

Ces éléments 120, 121, sont en contact, vers leur extrémité intérieure, avec la surface de l'élément 102a.These elements 120, 121 are in contact, towards their inner end, with the surface of the element 102a.

L'élément intérieur 122 est plié, notamment à angle droit, de manière à former un dièdre dont les deux faces sont parallèles, respectivement, aux éléments 120, 121 ; toutefois, les faces du dièdre 122 sont écartées des éléments 120, 121 de manière à déterminer entre eux un espace jl, propre à recevoir l'extrémité d'une barre diagonale, telle que 110b.The internal element 122 is folded, in particular at a right angle, so as to form a dihedral whose two faces are parallel, respectively, to the elements 120, 121; however, the faces of the dihedral 122 are separated from the elements 120, 121 so as to determine between them a space jl, suitable for receiving the end of a diagonal bar, such as 110b.

L'élément platl22 plié de manière à former un dièdre comporte, à mi-longueur de l'arête du dièdre, une fente f4, fermée à ses deux extrémités, coupant l'arête du dièdre et s'étendant sur une partie de chaque face du dièdre, suivant une direction perpendiculaire à l'arête.The platl22 element folded so as to form a dihedral comprises, at mid-length of the edge of the dihedral, a slot f4, closed at its two ends, cutting the edge of the dihedral and extending over a part of each face. dihedral, in a direction perpendicular to the edge.

La fente f4 a des dimensions suffisantes pour permettre le passage de l'ensemble des éléments 113a, 113b, écartés l'un de l'autre, comme visible sur la figure 6.The slot f4 has sufficient dimensions to allow the passage of all of the elements 113a, 113b, separated from one another, as visible in FIG. 6.

Les éléments 120, 121, 122 sont réunis aux autres éléments du noeud d'assemblage suivant les lignes formées par les arêtes des divers dièdres ou trièdres déterminés par ces éléments.The elements 120, 121, 122 are joined to the other elements of the assembly node along the lines formed by the edges of the various dihedrons or trihedra determined by these elements.

Les éléments 120, 121, 122 comportent des moyens d'accrochage notamment formés par des trous 109c pour les diverses barres diagonales.The elements 120, 121, 122 comprise attachment means in particular formed by holes 109c for the various diagonal bars.

Les éléments supplémentaires situés sur la gauche, selon la figure 6, par rapport à l'élément plat 102b, se déduisent des éléments 120, 121, 122 par la symétrie évoquée précédemment. La description de ces éléments n'est pas reprise ; les éléments en question sont désignés par les mêmes références, suivies de la lettre "s".The additional elements located on the left, according to FIG. 6 , relative to the flat element 102b, are deduced from the elements 120, 121, 122 by the symmetry mentioned previously. The description of these elements is not repeated; the elements in question are designated by the same references, followed by the letter "s".

La combinaison du premier élément plat 102 ou 102a, 102b muni d'une fente longitudinale à mi-largeur, avec le second élément plat 113 ou 113a, 113b, traversant cette fente, permet d'obtenir un noeud d'assemblage transmettant les efforts dans de bonnes conditions.The combination of the first flat element 102 or 102a, 102b provided with a mid-width longitudinal slot, with the second flat element 113 or 113a, 113b, passing through this slot, makes it possible to obtain an assembly node transmitting the forces under good conditions.

En effet, la petite dimension de la fente du premier élément plat 102 ou 102a, 102b, est orientée transversalement, et, de préférence, perpendiculairement à la direction des efforts transmis par élément plat.Indeed, the small dimension of the slot of the first flat element 102 or 102a, 102b, is oriented transversely, and, preferably, perpendicular to the direction of the forces transmitted by the flat element.

Il en résulte que la section utile de la matière de l'élément plat travaillant en traction ou en compression n'est que faiblement réduite au niveau de la fente, la largeur de cette fente étant égale (ou sensiblement égale) à l'épaisseur seulement de l'élément plat ou de l'ensemble d'éléments plats qui la traversent.It follows that the useful cross-section of the material of the flat element working in tension or in compression is only slightly reduced at the level of the slot, the width of this slot being equal (or substantially equal) to the thickness only of the flat element or of the set of flat elements which pass through it.

Dans le cas où le second élément plat 113 ne comporte pas de fente f2 les clés Cl, C2, montrées sur la figure 2 ne sont plus utilisées.In the case where the second flat element 113 does not have a slot f2, the keys C1, C2, shown in FIG. 2 are no longer used.

Les éléments plats supplémentaires tels que 105, 105a sont alors fixés aux faces des dièdres formées par les éléments 102, 113. Les deux éléments plats 105, 105a pourraient former les faces d'un dièdre obtenu par pliage d'une plaque suivant une arête qui viendrait, par exemple, s'appliquer contre le plat 113, pour y être fixée.The additional flat elements such as 105, 105a are then fixed to the faces of the dihedrons formed by the elements 102, 113. The two flat elements 105, 105a could form the faces of a dihedron obtained by folding a plate along an edge which would, for example, be applied against the plate 113, to be fixed there.

Généralement, lorsqu'il s'agit de noeuds d'assemblage pour une structure spatiale métallique, les plats constitutifs du noeud d'assemblage sont réalisés en acier courant du commerce. En effet, grâce aux bonnes conditions.dans lesquelles la matière travaille, il n'est pas nécessaire d'utiliser un acier présentant des caractéristiques mécaniques exceptionnelles.Generally, when it comes to assembly nodes for a metallic space structure, the constituent plates of the assembly node are made of commercially available steel. In fact, thanks to the good conditions in which the material works, it is not necessary to use a steel having exceptional mechanical characteristics.

L'assemblage des différents plats est alors réalisé par soudage.The assembly of the various dishes is then carried out by welding.

Le noeud d'assemblage propose par l'invention pourrait, naturellement, convenir pour tout type de charpente, notamment des charpentes en bois auquel cas les éléments plats constitutifs du noeud d'assemblage pourraient eux- mêmes être réalisés en bois, les fixations de ces différents éléments étant notamment assurées par collage.The assembly node proposed by the invention could, of course, be suitable for any type of frame, in particular wooden frames in which case the flat elements constituting the assembly node could themselves be made of wood, the fasteners of these various elements being in particular provided by gluing.

Chaque branche du noeud d'assemblage peut être constituée par un ou plusieurs plats juxtaposés de manière à obtenir l'épaisseur souhaitée pour la branche.Each branch of the assembly node can be formed by one or more juxtaposed dishes so as to obtain the desired thickness for the branch.

Les axes des différents éléments plats concourent au centre du noeud d'assemblage.The axes of the various flat elements compete in the center of the assembly node.

Chaque plat ou groupe de plats s'inscrit à l'intérieur de la section transversale de la barre de la structure spatiale qui vient s'attacher sur ce plat.Each dish or group of dishes fits within the cross section of the bar of the spatial structure which is attached to this dish.

Le noeud d'assemblage proposé peut être utilisé pour des maquettes ou même des jeux.The proposed assembly knot can be used for models or even games.

Ce noeud d'assemblage est d'une grande simplicité de conception de telle sorte qu'il peut être obtenu facilement et économiquement tout en permettant une grande précision d'usinage. Il en résulte que le jeu imposé par les assemblages normaux peut être pratiquement annulé ce qui autorise l'emploi d'organes de liaison économiques tels que des axes, des goupilles, des clavettes, etc.This assembly knot is very simple in design so that it can be obtained easily and economically while allowing great machining precision. As a result, the clearance imposed by normal assemblies can be practically canceled which authorizes the use of economic connecting members such as pins, pins, keys, etc.

En outre, il est possible de réaliser une grande standardisation des composants du noeud d'assemblage en effet, une série de trois ou quatre types de plats permet de couvrir économiquement non seulement toutes les formes géométriques de noeuds mais aussi de "reprendre" exactement l'effort à transmettre quelle que soit l'importance de celui-ci grâce à la combinaison de plusieurs plats de sections différentes.In addition, it is possible to achieve a great standardization of the components of the assembly node in fact, a series of three or four types of dishes makes it possible to economically cover not only all the geometric shapes of nodes but also to "pick up" exactly the 'effort to transmit whatever the importance of it through the combination of several dishes of different sections.

Ainsi, chaque branche du noeud d'assemblage peut être adaptée parfaitement à l'effort et à la géométrie de la liaison à effectuer.Thus, each branch of the assembly node can be perfectly adapted to the effort and to the geometry of the connection to be made.

Il est clair que le nombre des branches constituant le noeud est de préférence identique au nombre de barres de la structure spatiale que ce noeud doit assembler, l'orientation des branches étant déterminée en fonction de celles des barres à réunir.It is clear that the number of branches constituting the node is preferably identical to the number of bars of the spatial structure that this node must assemble, the orientation of the branches being determined as a function of those of the bars to be joined.
