Description
La présente addition conformément au brevet principal NO 84 12 229 se rapporte à un noeud d'assemblage destiné à la réalisation de structures spatiales réticulées et à l'organe de liaison entre les barres de structure et le noeud
Le but de la présente addition est d'augmenter de manière appréciable la productivité dans la fabrication et la mise en oeuvre de l'invention, d'améliorer de façon sensible la précision dans le montage des éléments, de faciliter les liaisons avec les ouvrages auxquels se rattachent les structures réalisées selon l'invention, d'accroltre la polyvalence des systèmes constructifs en découlant.The present addition in accordance with main patent NO 84 12 229 relates to an assembly node intended for the production of crosslinked spatial structures and to the connecting member between the structural bars and the node
The purpose of the present addition is to appreciably increase the productivity in the manufacture and implementation of the invention, to appreciably improve the precision in the assembly of the elements, to facilitate connections with the works to which are attached to the structures produced according to the invention, to increase the versatility of the resulting constructive systems.
On rappelle selon les caractéristiques du brevet principal que les noeuds sont constitués de sphères creuses composées de deux demi-sphères assemblées selon divers moyens décrits dans le brevet principal et percées de trous oblongs, permettant d'une part l'introduction et le blocage de la tête marteau de l'organe d'assemblage des barres de structure, et a d'autre part d'autoriser des variations directionnelles continues des dites barres. It will be recalled, according to the characteristics of the main patent, that the nodes consist of hollow spheres composed of two hemispheres assembled by various means described in the main patent and pierced with oblong holes, allowing on the one hand the introduction and the blocking of the hammer head of the assembly member of the structural bars, and on the other hand to allow continuous directional variations of the said bars.
Selon l'invention que constitue la présente addition le noeud comporte des trous oblongs dont la section droite affecte la forme d'un trapèze isocèle s'opposant au déboitement et assurant l'autocentrage de la tête applatie du boulon de liaison avec les barres de structure;la tête du dit boulon est de forme parallélépipédique comportant deux faces parallèles distantes d'une largeur inférieure à celle du trou oblong du noeud, et deux faces inclinées selon le même angle que celui fait par les parois du trou oblong, de telle sorte que le volume de la tête du boulon soit complémentaire de la cavité du trou oblong; les faces inclinées définissent en élévation vue de face un trapèze isocèle délimité par les bases supérieures et inférieures de la tête du boulon; les dièdres opposés formés par les faces inclinées et verticales de la tête du boulon sont arrondis pour affecter la forme d'une fraction de tronc de cône dont l'axe colncide avec celui du boulon et dont les rayons de la grande base et de la petite base ont respectivement pour valeur la moitié de la grande base et la moitié de la petite base du trapèze isocèle défini en élévation de face de la tête du boulon. According to the invention constituted by the present addition, the knot has oblong holes, the cross section of which affects the shape of an isosceles trapezoid opposing the disengagement and ensuring the self-centering of the flat head of the connecting bolt with the structural bars. ; the head of the said bolt is of parallelepiped shape having two parallel distant faces of a width less than that of the oblong hole of the knot, and two faces inclined at the same angle as that made by the walls of the oblong hole, so that the volume of the bolt head is complementary to the cavity of the oblong hole; the inclined faces define in front view elevation an isosceles trapezium delimited by the upper and lower bases of the bolt head; the opposite dihedrons formed by the inclined and vertical faces of the bolt head are rounded to affect the shape of a fraction of a truncated cone whose axis coincides with that of the bolt and whose radii of the large base and the small base respectively have the value of half of the large base and half of the small base of the isosceles trapezoid defined in front elevation of the bolt head.
Ces angles partiellement tronconiques peuvent être opposés vers la droite ou vers la gauche selon que l'on utilise un boulon comportant un filetage à droite ou à gauche
Un même noeud permet selon l'invention et lorsque les trous oblongs s'étendent de part et d'autre de l'équateur,la réalisation de structures à mailles de forme constante et à inclinaison variable des barres de treillis lorsque l'axe passant par les pôles est vertical, et des structures à maille de forme variable et à inclinaison constante des barres de treillis lorsque l'axe passant par les pôles est horizontal.These partially frusto-conical angles can be opposite to the right or to the left depending on whether a bolt having a right or left thread is used
According to the invention, the same node allows, when the oblong holes extend on either side of the equator, the production of mesh structures of constant shape and with variable inclination of the lattice bars when the axis passing through the poles is vertical, and mesh structures of variable shape and with constant inclination of the lattice bars when the axis passing through the poles is horizontal.
Ces propriétés découlant de l'invention augmentent la polyvalence des systèmes constructifs mettant en oeuvre l'invention. These properties resulting from the invention increase the versatility of the constructive systems implementing the invention.
Pour s'opposer lors du serrage du boulon aux poussées latérales sur les parois des trous oblongs il est, selon une variante conforme à l'invention, avantageux de surmonter la tête du boulon d'un relief saillant à l'intérieur du noeud de part et d'autre d'un trou oblong et prenant appui lors du serrage sur la paroi interne du noeud selon une portée sphérique de rayon identique à celui de la sphère intérieure du noeud. To oppose when tightening the bolt to the lateral thrusts on the walls of the oblong holes, it is, according to a variant according to the invention, advantageous to overcome the head of the bolt with a protruding relief inside the knot on the and on the other side of an oblong hole and taking support during tightening on the internal wall of the node according to a spherical surface of radius identical to that of the internal sphere of the node.
Afin de s'adapter aux caractéristiques géométriques des points d'appui des structures et/ou de raccorder à des ouvrages existants les structures réalisées selon l'invention, il est avantageux de réaliser, selon une variante conforme à l'invention, des noeuds affectant la forme d'une demi-sphère prolongée d'une base cylindrique comportant une rainure dans laquelle se fixe une platine solidarisée avec le dit noeud au moyen d'un boulon transversal. In order to adapt to the geometrical characteristics of the support points of the structures and / or to connect the structures produced according to the invention to existing structures, it is advantageous to produce, according to a variant in accordance with the invention, nodes affecting the shape of a hemisphere extended by a cylindrical base comprising a groove in which a plate fixed to the said node is fixed by means of a transverse bolt.
L'invention que constitue la présente addition va considérablement améliorer la productivité à la fabrication du noeud, en effet les trous oblongs s'étendant de part et d'autre de l'équateur du noeud et présentant une section trapézoldale, leur fabrication en une pièce par moulage au noyau est possible, la dépouille nécessaire à la fabrication et au démoulage du noyau étant assurée par l'inclinaison des parois du trou oblong. The invention constituted by the present addition will considerably improve the productivity in the manufacture of the knot, in fact the oblong holes extending on either side of the equator of the knot and having a trapezoidal section, their manufacture in one piece by core molding is possible, the draft necessary for the manufacture and demolding of the core being ensured by the inclination of the walls of the oblong hole.
La productivité à la mise en oeuvre des structures est nettement améliorée par la coopération entre la forme de la section du trou oblong et la forme de la tête du boulon; en effet la mise en place d'une barre de structure munie en ses extrémités d'un boulon fileté alternativement à droite et à gauche, et conforme à l'invention, se décompose en 3 phases::
l)Introduction par déplacement selon une direction perpendiculaire à l'orientation de la barre ,de la tête du boulon selon sa moindre dimension dans le trou oblong, la flêche du trou oblong étant supérieure à la hauteur de la tête du boulon
2)Rotation d'un quart de tour de la barre de structure, cette rotation ne nécessitant aucun déplacement axial de la barre compte tenu de la conicité partielle des dièdres opposés de la tête du boulon, l'immobilisation en position transversale de la dite tête se faisant par contact des parties planes des faces inclinées de la tête du boulon et des parois des trous oblongs; cette propriété est sécurisante en assurant un autopositionnement et un autoblocage de la barre de structure dans une position s'oppcsant à son déboitement; la mise en place des barres ne nécessitant aucun déplacement axial leur montage entre deux noeuds fixes s'effectue sans sujétions, ceci est important notamment lors de la fermeture des structures tridimensionnelles.The productivity in the implementation of the structures is clearly improved by the cooperation between the shape of the section of the oblong hole and the shape of the head of the bolt; in fact the installation of a structural bar provided at its ends with a threaded bolt alternately to the right and to the left, and in accordance with the invention, breaks down into 3 phases:
l) Introduction by displacement in a direction perpendicular to the orientation of the bar, of the head of the bolt according to its smallest dimension in the oblong hole, the arrow of the oblong hole being greater than the height of the head of the bolt
2) Quarter-turn rotation of the structural bar, this rotation requiring no axial displacement of the bar taking into account the partial conicity of the opposite dihedrons of the bolt head, immobilization in transverse position of said head by contacting the flat parts of the inclined faces of the bolt head and the walls of the oblong holes; this property is reassuring by ensuring self-positioning and self-locking of the structural bar in a position opposing its disengagement; the establishment of the bars requiring no axial displacement their mounting between two fixed nodes is carried out without constraints, this is important especially when closing three-dimensional structures.
Les boulons des extrémités des barres étant préférentieilement filetés à droite et à gauche il est possible de réaliser des réglages de structures par simple rotation des barres après montage
3) Serrage de l'écrou dont la base sphérique assure la convergence de l'axe de la barre sur le centre du noeud,la rotation de l'écrou contribuant à entraîner la barre vers l'autoblocage en rotation
Dans sa forme simplifiée composée d'une demi-sphère solidarisée à une platine, le noeud va faciliter l'adaptation des structures aux points d'appuis et/ou de raccordements, lorsque ces dits points constituent une surface plane; leur fabrication par moulage peut s'effectuer très économiquement en coquille; l'utilisation de ce noeud est également envisageable dans la réalisation de structures tridimensionnelles à simple nappe.The bolts of the ends of the bars being preferably threaded on the right and on the left it is possible to carry out adjustments of structures by simple rotation of the bars after assembly
3) Tightening of the nut whose spherical base ensures the convergence of the axis of the bar on the center of the knot, the rotation of the nut helping to drive the bar towards the self-locking in rotation
In its simplified form composed of a hemisphere secured to a plate, the knot will facilitate the adaptation of the structures to the points of support and / or connections, when these said points constitute a flat surface; their manufacture by molding can be carried out very economically in shell; the use of this knot is also conceivable in the production of three-dimensional structures with a single ply.
L'intérieur de la demi-sphère étant, la platine enlevée, accessible à partir de l'intérieur, il est conformément à l'invention possible et avantageux d'envisager la fixation des barres de structure au moyen d'un boulon à tête tronconique mis en place par l'intérieur du noeud et se vissant dans un taraudage réalisé à l'extrémité des barres de structure. The inside of the hemisphere being, the plate removed, accessible from the inside, it is according to the invention possible and advantageous to consider fixing the structural bars by means of a tapered bolt set up from inside the knot and screwed into a thread made at the end of the structural bars.
