Description

La présente invention concerne un système d'accrochage de poutre et, notamment, de poutre de longue portée.The present invention relates to a beam attachment system and, in particular, a long-span beam.

Les poutres et, notamment, les poutres de longue purée connaissent de nombreuses applications, en particulier dans le domaine des structures de grandes portées, pour la construction de bâtiments et d'ouvrages d'art. Des exemples de telles structures sont les entrepôts, hypermarchés, halls d'avions, centres sportifs, immeubles sur pilotis ou de grande hauteur, parkings, ponts et passerelles.The beams and, in particular, the long-mashed beams have many applications, particularly in the field of large span structures, for the construction of buildings and structures. Examples of such structures are warehouses, hypermarkets, aircraft halls, sports centers, buildings on stilts or high-rise, car parks, bridges and footbridges.

Le document FR 2 262 167 divulgue une structure de construction architecturale permettant de recevoir une couverture de grande surface, sans encombrements intérieur tels que piliers ou cloisons-porteuscs a l'aide d'éléments de charpentes métalliques disposés uniquement sur le périmètre extérieur et en utilisant des câbles sous tension comme supports longitudinaux, et comprenant en outre un portique a chaque extrémité et un ou plusieurs arceaux selon les dimensions.The document FR 2,262,167 discloses an architectural construction structure for receiving a large surface coverage, without interior dimensions such as pillars or bulkheads using metal frame members arranged only on the outer perimeter and using live cables as supports longitudinal, and further comprising a gantry at each end and one or more arches according to dimensions.

FR 2 611 781 divulgue un système permettant d'assurer l'appui et l'accrochage de poutres de longue portée. L'accrochage se fait sur des poteaux de support métalliques, chaque poteau étant muni d'au moins une jambe d'arc-boutement articulée à son extrémité inférieure sur un axe d'articulation solidaire du poteau correspondant. L'extrémité supérieure de la jambe d'arc-boutement est munie d'une cornière de réception sur laquelle vient porter un embout de coin solitaire de l'extrémité d'une poutre de longue portée par l'intermédiaire de pièces de contact dont est muni ledit embout. Grâce à ce système, la réaction verticale du poids de la poutre est transférée en effort d'arc-boutement dans l'axe de la jambe correspondant. Cet effort crée à son tour un effort horizontal de contrainte longitudinale dans la poutre correspondante de longe portée, destinée à supporter une structure. FR 2,611,781 discloses a system for providing support and attachment of long-span beams. Fastening is done on metal support posts, each post being provided with at least one arching leg hinged at its lower end on a hinge axis integral with the corresponding post. The upper end of the bracing leg is provided with a receiving angle on which is carried a solitary wedge end of the end of a long-span beam via contact pieces which is provided said tip. Thanks to this system, the vertical reaction of the weight of the beam is transferred in a bracing force in the axis of the corresponding leg. This effort in turn creates a longitudinal force of longitudinal stress in the corresponding beam of long reach, intended to support a structure.

La réfaction du poids de la poutre transférée en effort d'arc-boutement dans l'axe de la jambe sollicite en écartement les poteaux sur lesquels sont accrochées les poutres. On entend par-là que l'effort d'arc-boutement exerce un moment sur les poteaux. Lorsque l'on cherche à augmenter la portée de la poutre, une possibilité est d'augmenter la contrainte longitudinal dans la poutre. Or, un surcroît de contrainte dans la poutre entraîne un surcroît de moment, c'est-à-dirc une contrainte supplémentaire exercée sur les poteaux. Ce surcroît de moment peut conduire à son tour à une déformation ders poteaux telle qu'un flambement de flexion ou à une rupture lorsque le seuil de résistance en flexion du poteau est franchi. Une déformation de poteau menace la stabilité du système d'accrochage. A plus forte raison, une rupture d'une poutre n'est évidemment pas souhaitable.The reduction of the weight of the beam transferred in the effort of buttressing in the axis of the leg solicits in spacing the posts on which are hung the beams. This means that the bracing force exerts a moment on the posts. When looking to increase the span of the beam, one possibility is to increase the longitudinal stress in the beam. However, an additional stress in the beam causes an additional moment, that is to say an additional stress exerted on the poles. This extra moment can in turn lead to deformation of posts such as bending buckling or breaking when the bending resistance threshold of the pole is crossed. Post deformation threatens the stability of the fastening system. All the more reason, a breaking of a beam is obviously not desirable.

Il existe donc un besoin pour un système d'accrochage de poutre qui permette d'augmenter la portée de la poutre et de préserver la stabilité du système.There is therefore a need for a beam attachment system that allows to increase the span of the beam and preserve the stability of the system.

L'invention a pour objet un système d'accrochage de poutre comprenant deux poteaux, une poutre et au moins un tirant, dans lequel les poteaux sont sollicités en écartement par la poutre et sollicités en rapprochement par le tirant, la poutre est reliée au tirant et la poutre et le tirant sont montés à coulissement relatif selon une portion finie de coulissement.The invention relates to a beam attachment system comprising two posts, a beam and at least one tie rod, in which the posts are biased by the beam and urged closer by the tie rod, the beam is connected to the tie rod and the beam and the tie are mounted relative sliding in a finite portion of sliding.

L'invention propose un système d'accrochage de poutre comprenant deux poteaux, une poutre et au moins un tirant, dans lequel les poteaux sont sollicités en écartement par la poutre et sollicités en rapprochement par le tirant. Le tirant compense au moins en partie la contrainte exercée par la poutre sur le poteau. Ce système permet d'allonger la portée de la poutre et de préserver la stabilité du système.The invention proposes a beam attachment system comprising two posts, a beam and at least one tie, in which the posts are biased by the beam and urged closer by the tie rod. The tie compensates at least in part the stress exerted by the beam on the pole. This system makes it possible to extend the span of the beam and preserve the stability of the system.

La figure est une illustration schématique du système d'accrochage selon l'invention. La figure montre un poteau de rive 14 ainsi que plusieurs poteaux 5a, 5b, des poutres 3a, 3b, 3c et des tirants 9a, 9b, 9c. Les poteaux 5a, 5b sont encastrés dans le sol 4 (c'est-à-dire dans la fondation) et forment une charpente métallique destinée à l'accrochage des poutres. Le numéro de référence général 3 désigne une poutre, le numéro 9 désigne un tirant et le numéro 5 désigne un poteau de charpente autre qu'un poteau de rive. Les lettres de références additionnelles a, b, c désignent différentes sections de la charpente. Une poutre est accrochée entre deux poteaux à l'aide de systèmes d'appui qui seront décrite plus loin. Le tirant est un élément du système destiné à résister à la traction. Il peut par exemple être fixé en tête d'un poteau et être réalisé sous la forme d'un câble ou d'un arbre tendu. Le système d'accrochage I de poutre selon l'invention comprend donc deux poteaux 5a, 5b, une poutre 3b et au moins un tirant 9b. La poutre est mise sous contrainte et le tirant relie au moins l'un des poteaux 5a, 5b, de sorte que les deux poteaux 5a, 5b sont sollicités en écartement par la poutre 3b et sollicités en rapprochement par le tirant 9b. La sollicitation par le tirant 9h compense au moins partiellement le moment exercé par une poutre sur les poteaux et crée en outre un surcroît de contrainte longitudinale dans la poutre. Ce système permet ainsi, d'une part, d'allonger la portée de la poutre et, d'autre part, de reprendre une partie de l'effort de contrainte exercé sur un poteau. Il permet donc également de préserver la stabilité du système.The figure is a schematic illustration of the attachment system according to the invention. The figure shows a bank post 14 as well as several posts 5a, 5b, beams 3a, 3b, 3c and tie rods 9a, 9b, 9c. The posts 5a, 5b are embedded in the ground 4 (that is to say in the foundation) and form a metal frame for fastening the beams. The general reference number 3 designates a beam, the number 9 designates a tie rod and the number 5 designates a frame stud other than a rim pole. The additional reference letters a, b, c designate different sections of the frame. A beam is hung between two posts with support systems that will be described later. The tie rod is a part of the system designed to withstand traction. It can for example be fixed at the head of a pole and be made in the form of a cable or a tight shaft. The beam attachment system I according to the invention thus comprises two posts 5a, 5b, a beam 3b and at least one tie 9b. The beam is stressed and the tie rod connects at least one of the posts 5a, 5b, so that the two posts 5a, 5b are biased by the beam 3b and urged closer by the tie 9b. The biasing by the tie 9h compensates at least partially the moment exerted by a beam on the poles and further creates an additional longitudinal stress in the beam. This system thus makes it possible, on the one hand, to lengthen the span of the beam and, on the other hand, to take back part of the stress exerted on a pole. It also helps to preserve the stability of the system.

La figure 2 est une vue de face et en coupe représentant la partie supérieure d'un poteau relié à deux poutres par l'intermédiaire de bielles. La figure montre un poteau 5a, deux poutres 3a, 3b, un calage vertical 17, deux bielles 13a,13b, deux plaques de répartition 19a, 19b et deux tirants 9a, 9b. Un élément a de chaque paire d'éléments a, h précitée se situe à gauche du poteau 5a, l'autre élément se situant à la droite du poteau. Le poteau 5a est encastré dans le sol 4 dans cet exemple et, plus particulièrement, dans la fondation. Selon une variante il peut être articulé sur la fondation. Le poteau 5a est relié aux poutres 3a, 3b par l'intermédiaire d'une bielle 13a,13b articulée d'une part au poteau 5a qu'elle relie à une poutre et d'autre part a une poutre 3a, 3b. L'articulation au niveau du poteau 5a peut être réalisée au moyen d'une liaison pivot 14a, 14b ou, en variante, d'un axe. L'articulation au niveau de la poutre peut, elle, être réalisée au moyen d'une cornière de support 18a, 18b. Une cornière d'embout peut alors être articulée dans la cornière de support 18a, 18b de sorte à former une liaison pivot. Par exemple, la cornière d'embout peut être réalisée sous la forme d'une plaque de répartition 19a, 19b. Cette plaque fixée à une poutre 3a, 3b permet, d'une part, de supporter cette poutre et, d'autre part, de répartir la réaction du support dans cette poutre 3. Deux tirants 9a, 9b sont fixés en tête du poteau 5a, à gauche et à droite, respectivement.The figure 2 is a front view in section showing the upper part of a pole connected to two beams via connecting rods. The figure shows a pole 5a, two beams 3a, 3b, a vertical wedge 17, two connecting rods 13a, 13b, two distribution plates 19a, 19b and two tie rods 9a, 9b. An element a of each pair of elements a, h mentioned above is located to the left of the pole 5a, the other element being to the right of the pole. The pole 5a is embedded in the ground 4 in this example and, more particularly, in the foundation. According to a variant it can be articulated on the foundation. The pole 5a is connected to the beams 3a, 3b by means of a connecting rod 13a, 13b hinged on the one hand to the pole 5a that it connects to a beam and on the other hand to a beam 3a, 3b. The articulation at the pole 5a can be achieved by means of a pivot connection 14a, 14b or, alternatively, an axis. The articulation at the level of the beam can itself be achieved by means of a support bracket 18a, 18b. An end angle can then be articulated in the support angle 18a, 18b so as to form a pivot connection. For example, the end angle may be in the form of a distribution plate 19a, 19b. This plate fixed to a beam 3a, 3b makes it possible, on the one hand, to support this beam and, on the other hand, to distribute the reaction of the support in this beam 3. Two tie rods 9a, 9b are fixed at the top of the pole 5a , left and right, respectively.

Selon une variante, seul un tirant est fixé en tête du poteau 5a. Un même tirant peut alors s'étendre le long d'une charpente comprenant plusieurs poteaux. Une telle structure présente l'avantage de répartir les efforts de contraintes, ainsi que la reprise de ces efforts, le long de la charpente. Il s'ensuit une meilleure cohésion de la charpente.According to a variant, only one tie is fixed at the top of the pole 5a. A same tie can then extend along a frame comprising several poles. Such a structure has the advantage of distributing the stress forces, as well as the recovery of these efforts, along the frame. It follows a better cohesion of the frame.

Les tirants sont au moins partiellement escamotés dans la poutre, comme il sera décrit plus loin. Un calage 17 des deux poutres, en tête du poteau 5a, peut en outre être assuré par deux éléments de calage, situés de part et d'autre des poutres. Ceci sera mieux décrit en référence à la figure 3.The tie rods are at least partially retracted into the beam, as will be described later. A wedging 17 of the two beams, at the head of the pole 5a, can also be provided by two wedging elements, located on either side of the beams. This will be best described with reference to the figure 3 .

La figure 3 est une vue de dessus des éléments représentés sur la figure 2. Chacune des poutres 3a, 3b comprend deux parties latérales, respectivement référencés sur la figure 3 sous 3aG, 3aD, 3bG et 3bD. Les deux parties latérales sont assemblées et reliées par des éléments de fixation 20a, 20b tels que des boulons. Ces éléments de fixation traversent une plaque de répartition 19a, 19b, telle que représentées sur la figure 2. Ces plaques sont cependant occultées par un tirant 9a, 9b et ne sont donc pas visibles sur la figure 3. Les parties latérales 3aG, 3aD, 3bG, 3bD sont enserrées au niveau de leur tête par les deux éléments de calage 17G, 17D, lesquels peuvent ainsi empêcher le déversement des poutres. D'autres éléments fixation 16 assurent le maintien des éléments de calage 17 enserrant la tête des poutres 3a, 3b. Un passage 15a, 15b est formé entre deux parties latérales, permettant à un tirant 9a, 9b de s'y engager. La section des demi-poutres peut être conçue de telle sorte qu'après l'assemblage des deux demi-poutres, un passage 15a, 15b forme une rigole permettant à un tirant 9a, 9b de s'y engager. Un tirant 9a, 9b est ainsi au moins partiellement escamoté dans une poutre, ce qui permet de le protéger, par exemple en cas d'incendie. Dans le mode de réalisation représenté sur la figure 3, deux tirants 9a, 9b sont fixés en tête du poteau 5a.The figure 3 is a top view of the elements represented on the figure 2 . Each of the beams 3a, 3b comprises two lateral parts, respectively referenced on the figure 3 under 3aG, 3aD, 3bG and 3bD. The two lateral parts are assembled and connected by fixing elements 20a, 20b such as bolts. These fasteners pass through a distribution plate 19a, 19b, as shown in FIG. figure 2 . These plates are however obscured by a tie 9a, 9b and are therefore not visible on the figure 3 . The side portions 3aG, 3aD, 3bG, 3bD are clamped at their head by the two wedging elements 17G, 17D, which can thus prevent the spill of the beams. Other fixing elements 16 maintain the wedging elements 17 enclosing the head of the beams 3a, 3b. A passage 15a, 15b is formed between two lateral parts, allowing a tie 9a, 9b to engage. The section of the half-beams can be designed so that after assembly of the two half-beams, a passage 15a, 15b forms a channel allowing a tie 9a, 9b to engage. A tie 9a, 9b is thus at least partially retracted into a beam, which allows to protect it, for example in case of fire. In the embodiment shown on the figure 3 two tie rods 9a, 9b are fixed at the top of the pole 5a.

La figure 4 est une vue partielle, de face, d'un tirant fixé en tête d'un poteau et au niveau d'une extrémité d'une poutre. La ligure montre un tirant 9b, la tête d'un poteau 5a, une poutre 3b ainsi qu'un organe de tension 23b du tirant 9b. Cet organe 23b permet d'ajuster la tension du tirant 9b, par exemple après le montage de la poutre 3b sur les poteaux et du tirant avec la poutre.The figure 4 is a partial front view of a tie rod fixed at the head of a pole and at one end of a beam. The figure shows a tie 9b, the head of a pole 5a, a beam 3b and a tension member 23b of the tie 9b. This member 23b makes it possible to adjust the tension of the tie rod 9b, for example after the mounting of the beam 3b on the posts and the drawing with the beam.

La figure 5 est une vue en coupe transversale d'une poutre, au niveau d'une section centrale de la poutre. Cette figure montre une poutre 3 comprenant deux parties latérales (ou demi-poutres) gauche et droite 3G, 3D reliées fixement par des éléments de fixation 20. La figure montre également une partie de poteau 5 et une bielle 13 articulée au poteau 5 via une liaison pivot 14 et en contact avec la poutre 3 au niveau d'une plaque de répartition 19 de la poutre. Les éléments de fixation 20 traversent cette plaque 19. Les parties latérales gauche 3G et droite 3D de la poutre 3 forment un passage 15 permettant à un tirant (non représenté) de s'y engager.The figure 5 is a cross-sectional view of a beam, at a central section of the beam. This figure shows a beam 3 comprising two lateral parts (or half-beams) left and right 3G, 3D fixedly connected by fixing elements 20. The figure also shows a portion of post 5 and a rod 13 articulated to the post 5 via a pivot connection 14 and in contact with the beam 3 at a distribution plate 19 of the beam. The fastening elements 20 pass through this plate 19. The left-hand 3G and right-hand 3D parts of the beam 3 form a passage 15 allowing a tie rod (not shown) to engage with it.

Il convient de noter que le passage 15 de tirant est autant de matériau en moins dans la poutre. Outre ce qu'il permet au tirant d'être engagé à l'intérieur de la poutre pour la soutenir, le passage 15 libère de la matière et allège donc la poutre 3. La poutre 3 est ainsi moins sujette au flambage causé par sa propre masse. En outre, l'escamotage du tirant à l'intérieur du passage 15 diminue l'encombrement spatial du tirant et permet de protéger le tirant, par exemple, en cas d'incendie. Au besoin, un film ignifuge peut être fixé de sorte à fermer le passage 15, afin de protéger davantage le tirant en cas d'incendie.It should be noted that the pulling passage 15 is less material in the beam. In addition to allowing the tie rod to be engaged within the beam to support it, the passage 15 releases material and thus lighten the beam 3. The beam 3 is thus less subject to buckling caused by its own. mass. In addition, the retraction of the tie rod inside the passage 15 reduces the space requirement of the tie rod and makes it possible to protect the tie rod, for example, in the event of a fire. If necessary, a fire retardant film may be attached to close the passage 15 to further protect the tie rod in case of fire.

Dans un mode de réalisation, le passage 15 est formé de sorte que le tirant viennent soutenir la poutre au niveau du centre de gravité de la poutre. Une plaque de répartition 41 centrale de la poutre repose sur le tirant 9. Cette plaque 41 centrale est traversée par des éléments de fixation 40 reliant fixement les deux parties latérales 3G, 3D de poutre via la plaque 41 centrale.In one embodiment, the passage 15 is formed such that the tie rods support the beam at the center of gravity of the beam. A central distribution plate 41 of the beam rests on the tie rod 9. This central plate 41 is traversed by fastening elements 40 fixedly connecting the two lateral parts 3, 3, 3 of beam via the central plate 41.

De plus, le passage 15 de tirant formé par les parties latérales 3G, 3D permet un coulissement relatif de la poutre par rapport au tirant. Une telle caractéristique permet à la poutre 3 de s'ajuster naturellement par rapport au tirant 9. Cette dernière propriété du système d'accrochage se révèle particulièrement avantageuse lorsque la poutre 3 est soumise à une charge dissymétrique. Ceci est par exemple le cas lorsque des équipements tels que des équipements de climatisation ou de chauffage sont fixés en appui sur la poutre en un endroit éloigné du centre de la poutre. Dans un tel cas, le degré de liberté supplémentaire offert par le coulissement relatif de la poutre 3 par rapport au tirant 9 permet de réduire l'énergie potentielle liée à la contrainte de charge. Une telle propriété permet donc de stabiliser davantage le système d'accrochage.In addition, the pulling passage 15 formed by the lateral portions 3G, 3D allows relative sliding of the beam relative to the tie rod. Such a characteristic allows the beam 3 to adjust naturally with respect to the tie rod 9. This latter property of the attachment system is particularly advantageous when the beam 3 is subjected to an asymmetrical load. This is for example the case when equipment such as air conditioning or heating equipment is fixed in support on the beam at a place remote from the center of the beam. In such a case, the additional degree of freedom offered by the relative sliding of the beam 3 relative to the tie rod 9 makes it possible to reduce the potential energy related to the load stress. Such a property thus makes it possible to further stabilize the fastening system.

Il convient toutefois de noter que si dans le présent mode de réalisation, la poutre 3 est soutenue par le tirant 9, celle-ci peut également être reliée au tirant selon diverses variantes possibles.However, it should be noted that if in the present embodiment, the beam 3 is supported by the tie rod 9, it can also be connected to the tie rod in various possible variants.

Selon une variante, le tirant peut soutenir la poutre par l'intermédiaire d'un anneau ou d'un organe de liaison équivalent permettant à la poutre 3 de coulisser le long du tirant.Alternatively, the tie rod can support the beam through a ring or equivalent connecting member allowing the beam 3 to slide along the tie rod.

Selon une autre variante, le tirant est simplement fixé à la poutre, par exemple au centre de la surface supérieure de la poutre. Cette variante permet de simplifier la fabrication du système d'accrochage 1. On obtient cc-faisant un système d'accrochage 1 dans lequel la sollicitation de poteaux par un tirant compense au moins partiellement le moment exercé par la poutre 3 sur les poteaux et crée en outre un surcroît de contrainte longitudinale dans la poutre 3. Un tel système d'accrochage bénéficie d'une grande simplicité de montage, permet d'allonger la portée de la poutre et de reprendre une partie de l'effort de contrainte exercé sur un poteau. Le fait que le tirant relie la poutre 3 permet en outre de stabiliser l'ensemble poutre - poteaux du système d'accrochage.According to another variant, the tie rod is simply fixed to the beam, for example in the center of the upper surface of the beam. This variant makes it possible to simplify the manufacture of the fastening system 1. This produces a fastening system 1 in which the solicitation of posts by a tie compensates at least partially the moment exerted by the beam 3 on the posts and creates in addition, an additional longitudinal stress in the beam 3. Such a fastening system has a great simplicity of assembly, allows to extend the span of the beam and to take back part of the stress exerted on a post. The fact that the tie rod connects the beam 3 also makes it possible to stabilize the beam-post assembly of the fastening system.

Selon une autre variante, le tirant peut être réalisé en deux parties de tirants distinctes. L'une de ces parties relie un poteau à la poutre et l'autre de ces parties relie la poutre à un autre poteau. Il est alors obtenu une structure tirant - poteaux - poutre de type haubané dans laquelle chacune des deux parties de tirants compense au moins partiellement le moment exercé par la poutre sur chacun des poteaux.According to another variant, the tie rod can be made in two parts of separate tie rods. One of these parts connects a pole to the beam and the other of these parts connects the beam to another pole. It is then obtained a pulling structure - posts - guyed type beam in which each of the two parts tie rods at least partially compensates for the moment exerted by the beam on each of the poles.

Par ailleurs, il a été mentionné plus haut que le degré de liberté supplémentaire offert par le coulissement relatif de la poutre 3 par rapport au tirant 9 permettait de réduire l'énergie potentielle liée à la contrainte de charge et de stabiliser davantage le système d'accrochage. Cependant, il est possible de limiter le coulissement relatif de la poutre par rapport au tirant, afin de prévenir une instabilité du système d'accrochage. A cette fin, un manchon 43 fixé sur le tirant 9 limite le coulissement de la poutre par rapport au tirant. Ceci sera mieux décrit en référence à la figure 6.Furthermore, it has been mentioned above that the additional degree of freedom offered by the relative sliding of the beam 3 with respect to the tie rod 9 made it possible to reduce the potential energy related to the load stress and to further stabilize the system. hanging. However, it is possible to limit the relative sliding of the beam relative to the tie rod, to prevent instability of the attachment system. To this end, a sleeve 43 fixed on the tie rod 9 limits the sliding of the beam relative to the tie rod. This will be best described with reference to the figure 6 .

La figure 6 est une vue partielle et en coupe, le long d'une section longitudinale de la poutre, au niveau de sa partie centrale. La figure montre la partie centrale d'une poutre 3 comprenant deux parties latérales. La coupe est réalisée entre ces deux parties latérales. Le tirant 9 est engagé dans le passage de tirant formé par les parties latérales de poutres et permet un coulissement relatif de la poutre 3 par rapport au tirant 9. Dans un mode de réalisation, illustré à titre d'exemple sur la figure 6, la poutre 3 et le tirant 9 sont montés à coulissement relatif selon une portion finie de coulissement. La portion de glissement est délimitée par deux manchons 43, 45 fixés sur le tirant 9. Les deux parties latérales de poutres sont reliées par une plaque de répartition 41 centrale, percée de plusieurs trous permettant la fixation de la plaque 41 sur les deux parties latérales. La plaque de répartition centrale peut ainsi coulisser le long du tirant 9 et entre les manchons. La différence entre la portion finie de coulissement et la longueur de la plaque de répartition définit un jeu de coulissement, comme illustré sur la figure 6.The figure 6 is a partial view in section, along a longitudinal section of the beam, at its central portion. The figure shows the central part of a beam 3 comprising two lateral parts. The cut is made between these two lateral parts. The tie rod 9 is engaged in the pulling passage formed by the lateral portions of beams and allows relative sliding of the beam 3 with respect to the tie rod 9. In one embodiment, illustrated by way of example on FIG. figure 6 , the beam 3 and the tie rod 9 are mounted relative sliding in a finite portion of sliding. The sliding portion is delimited by two sleeves 43, 45 fixed on the tie 9. The two lateral portions of the beams are connected by a central distribution plate 41, pierced with several holes for fixing the plate 41 on the two lateral parts. . The central distribution plate can slide along the tie rod 9 and between the sleeves. The difference between the finished sliding portion and the length of the distribution plate defines a sliding clearance, as illustrated in FIG. figure 6 .

Selon une variante, les plaques de répartition 19. 41 se subdivisent clles-mêmes en deux plaques. Chacune de ces deux plaques peut être pré-asscmblée sur une partie latérale de poutre 3G, 3D. Ainsi, la phase d'assemblage de la poutre 3 ne nécessite plus que l'assemblage directement par fixation des parties latérales de poutre, par exemple au moyen de boulons. D'autre part, la phase de pré-assemblage étant une phase d'usine, elle peut être facilement maîtrisée. Des erreurs éventuelles lors de l'assemblage de la poutre sont ainsi écartées. L'assemblage de la poutre 3 sur un chantier s'en trouve substantiellement simplifié.According to a variant, the distribution plates 19. 41 are subdivided into two identical plates. Each of these two plates can be pre-assembled on a lateral part of a 3G, 3D beam. Thus, the assembly phase of the beam 3 only requires assembly directly by fixing the side portions of the beam, for example by means of bolts. On the other hand, since the pre-assembly phase is a factory phase, it can be easily controlled. Possible errors during assembly of the beam are thus discarded. The assembly of the beam 3 on a construction site is substantially simplified.

Le jeu de coulissement est typiquement compris entre 0,2/10000e et 5/10000e de la portée de la poutre. Ce jeu est choisi de sorte à être largement inférieur à un seuil d'instabilité du système d'accrochage, c'est-à-dire un seuil au-delà duquel le coulissement de la poutre 3 menace la stabilité du système. Une telle caractéristique permet à la poutre 3, articulée par ailleurs à des bielles, de s'ajuster par rapport au tirant 9, à l'intérieur d'une portion de coulissement délimitée. Ainsi, lorsque la poutre 3 est soumise à une charge dissymétrique, le degré de liberté supplémentaire fourni par le coulissement relatif de la poutre 3 par rapport au tirant permet de réduire l'énergie potentielle liée à la contrainte de charge. Une telle propriété permet de stabiliser le système d'accrochage, comme décrit ci-avant. Pour autant, le coulissement s'effectue à l'intérieur d'une portion de coulissement finie (délimitée par des manchons), afin d'éviter que la poutre ne coulisse au-delà du seuil d'instabilité du système d'accrochage.The sliding clearance is typically between 0.2 / 10000 5/10000 e and e of the span of the beam. This game is chosen to be much lower than a threshold of instability of the attachment system, that is to say a threshold beyond which the sliding of the beam 3 threatens the stability of the system. Such a feature allows the beam 3, also hinged to connecting rods, to adjust relative to the tie rod 9, within a delimited sliding portion. Thus, when the beam 3 is subjected to an asymmetrical load, the additional degree of freedom provided by the relative sliding of the beam 3 relative to the tie rod reduces the potential energy related to the load stress. Such a property makes it possible to stabilize the fastening system, as described above. However, the sliding takes place inside a finite sliding portion (delimited by sleeves), in order to prevent the beam from sliding beyond the threshold of instability of the fastening system.

La figure 7 montre une vue de face, représentant une poutre destinée à être montée dans le système d'accrochage. La poutre 3 se subdivise en trois segments longitudinaux 31,32,33. Le troisième segment 33 est semblable au premier segment 31 mais orienté de façon symétrique par rapport à la section transversale, centrale de la poutre 3. Chacun des segments se termine par un décrochement à l'une, au moins, de ses extrémités, comme représenté sur la figure, de sorte que l'assemblage des segments soit facilité. De préférence, le segment central 32 présente un décrochement tel qu'il repose sur les deux autres segments 31,33. Des plaques de fixation 34 viennent consolider la poutre 3 au niveau des décrochements. Pris séparément, ces segments 31,32,33 sont plus maniables qu'une poutre d'un seul tenant, ce qui simplifie considérablement la logistique relative à la livraison du système d'accrochage sur un chantier. En outre, l'utilisation de segments permet de ne pas avoir à recourir à un transport exceptionnel et, donc, de réduire le coût de revient d'une poutre assemblée.The figure 7 shows a front view, showing a beam to be mounted in the attachment system. The beam 3 is subdivided into three longitudinal segments 31,32,33. The third segment 33 is similar to the first segment 31 but oriented symmetrically with respect to the central cross-section of the beam 3. Each of the segments terminates in a recess at one, at least, of its ends, as shown in the figure, so that the assembly of the segments is facilitated. Preferably, the central segment 32 has a recess such that it rests on the other two segments 31,33. Fastening plates 34 consolidate the beam 3 at the recesses. Taken separately, these 31,32,33 segments are more manageable than a beam in one piece, which considerably simplifies the logistics relating to the delivery of the attachment system on a building site. In addition, the use of segments makes it possible not to have to resort to an exceptional transport and, therefore, to reduce the cost price of an assembled beam.

On peut, au besoin, prévoir autant de segments de poutres qu'il est nécessaire pour ne pas avoir à recourir à un transport exceptionnel. Une telle conception de système d'accrochage, selon l'invention, permet d'envisager la réalisation de poutres de longueur allant de 5 à 120 m. Il est, en lait, théoriquement possible de réaliser des poutres de longueurs supérieures à 120 m, dans un système d'accrochage selon l'invention, en adaptant les dimensions générales des poutres et des poteaux. Parmi les longueurs de poutres typiquement envisagées dans le système d'accrochage selon l'invention, on peut citer les longueurs suivantes: 18, 24, 30, 35, 40, 55 et 70 m.If necessary, as many segments of beams can be provided as necessary to avoid the need for exceptional transportation. Such a fastening system design, according to the invention, makes it possible to envisage the production of beams of length ranging from 5 to 120 m. In theory, it is theoretically possible to produce beams of lengths greater than 120 m in a fastening system according to the invention, by adapting the overall dimensions of the beams and columns. Among the lengths of beams typically envisaged in the fastening system according to the invention, the following lengths may be mentioned: 18, 24, 30, 35, 40, 55 and 70 m.

Le matériau utilisé pour la poutre est du lamellé-collé. En variante, on peut utiliser un profil d'acier reconstitué soudé.The material used for the beam is glulam. Alternatively, a welded reconstituted steel profile may be used.

Typiquement, le tirant est en acier ou est dérivé de l'acier et présente un module d'élasticité compris entre 190.000 et 230.000 MPa.Typically, the tie is made of steel or is derived from steel and has a modulus of elasticity of between 190,000 and 230,000 MPa.

L'invention n'est cependant pas limitée aux variantes décrites ci-avant mais est susceptible de nombreuses autres variations aisément accessibles à l'homme du métier. Par exemple, on peut envisager de scinder une poutre en un nombre impair quelconque de segments longitudinaux. Un nombre impair de segments permet d'envisager une poutre symétrique par rapport à sa section transversale, centrale, la poutre comprenant un segment central reposant sur le tirant. Le nombre de segments peut ensuite être optimisé de sorte à réduire le coût global de montage du système d'accrochage.The invention is however not limited to the variants described above but is capable of many other variations easily accessible to those skilled in the art. For example, it is conceivable to split a beam into any odd number of longitudinal segments. An odd number of segments makes it possible to envisage a beam that is symmetrical with respect to its central cross-section, the beam comprising a central segment resting on the tie rod. The number of segments can then be optimized to reduce the overall cost of mounting the attachment system.
