Abstract

A first tie rod (10A) is provided with a threaded rod (12) on which a nut (13) of a second tie rod (10B) is screwed. The threaded rod is engaged in a hole (14) in the centre (30) of the beam (2). The first tie rod is provided with a support (15) comprising a strap (16) having two rings (17,18) distanced from each other to form a throat (19). The nut also has a strap (16) with two rings (17,18) with a throat formed between them. The beam centre is locked between the support and the nut. The external edges of the rings adjacent to the beam centre define a surface situated in the volume (V) in the axial extension of the external wall of the first or second tie rod and between the extreme edges (100,101) of the tie rods between which the beam centre is fixed.

Description

La présente invention a pour objet un système pour relier ensemble des poutres qui font partie d'une structure montée sur une structure ou armature principale. Ce système comprend des tirants qui sont placés dans le prolongement l'un de l'autre, l'âme d'une poutre étant fixée entre deux tirants placés dans le prolongement l'un de l'autre.The present invention relates to a system for connecting together beams which are part of a structure mounted on a main structure or frame. This system comprises tie rods which are placed in the extension of one another, the core of a beam being fixed between two tie rods placed in the extension of one another.

Les tirants sont connus pour reprendre des forces de traction ou de compression (poussée) et pour assurer une résistance à la torsion suffisante, grâce à quoi les déplacements latéraux et la torsion des poutres, par exemple de toitures, de mezzanines et de supports de palettes, peuvent être évités.The tie rods are known to take up tensile or compressive forces (thrust) and to ensure sufficient resistance to torsion, whereby the lateral displacements and the torsion of the beams, for example of roofs, mezzanines and pallet supports , can be avoided.

Par exemple, le brevet US-A-5 077 953 décrit un écarteur qui n'empêche pas la torsion des poutres. L'écarteur nécessite une perforation importante des poutres, cette perforation affaiblissant les poutres. Les lignes de force ne s'étendent pas dans le prolongement l'une de l'autre. Des forces parasitaires sont ainsi créées, elles-ci réduisant la solidité des matériaux utilisés.For example, US-A-5,077,953 describes a spacer which does not prevent the torsion of the beams. The retractor requires significant perforation of the beams, this perforation weakening the beams. The main lines do not extend in line with each other. Parasitic forces are thus created, which reduce the solidity of the materials used.

Un autre système est constitué par le soudage d'une plaque extrême sur un tirant. On relie deux plaques extrêmes de deux tirants avec interposition entre eux d'une poutre, au moyen de boulons. Le coût d'un tel système est onéreux par rapport à la solution proposée par l'invention. La surface de la buse prézinguée est abîmée et perd dès lors de sa résistance à la corrosion.Another system consists of welding an end plate to a tie rod. Two end plates of two tie rods are connected with a beam between them, using bolts. The cost of such a system is expensive compared to the solution proposed by the invention. The surface of the nozzle pre-galvanized is damaged and therefore loses its resistance to corrosion.

Un grand défaut de ce système est son montage compliqué de par le fait que deux boulons doivent être engagés dans les plaques d'extrémité et dans la poutre située à une hauteur élevée.A big drawback of this system is its complicated assembly due to the fact that two bolts have to be engaged in the end plates and in the beam located at a high height.

Le brevet anglais GB-B-2169678 permet d'éviter mais de façon insuffisante la torsion de la poutre qui est fixée entre deux tirants, car les deux demi-supports des boulons s'ouvrent par cisaillement par le moment de flexion dans le tirant.British patent GB-B-2169678 makes it possible to avoid, but insufficiently, the torsion of the beam which is fixed between two tie rods, since the two half-supports of the bolts open by shearing by the bending moment in the tie rod.

Les problèmes ci-dessus sont résolus par la présente invention par l'utilisation d'écrous et d'appuis, chacun de préférence réalisé en une pièce sans pièce intermédiaire.The above problems are solved by the present invention by the use of nuts and supports, each preferably made in one piece with no intermediate piece.

Le système suivant l'invention est un système qui présente une résistance suffisante à la flexion, qui peut résister à des hautes forces de traction et de pression, par quoi l'âme d'une poutre est fixée fermement (le desserrage étant difficile), et qui peut facilement être monté.The system according to the invention is a system which has sufficient resistance to bending, which can withstand high tensile and pressure forces, whereby the core of a beam is firmly fixed (loosening being difficult), and which can easily be mounted.

Selon un système selon l'invention, système pour relier ensemble des poutres d'une structure entre des points de fixation de ces poutres sur une structure principale, ledit système comprend des tirants axiaux situés dans le prolongement l'un de l'autre. L'âme d'une poutre est fixée entre deux tirants situés dans le prolongement l'un de l'autre, un premier tirant étant muni d'une tige filetée sur laquelle un écrou d'un deuxième tirant est vissé, ladite tige filetée étant engagée dans un trou que présente l'âme. Le premier tirant est muni d'un appui de sorte que l'âme de la poutre est bloquée entre ledit appui et l'écrou. Cet appui ou écrou comprend une bride qui est munie d'au moins une protubérance ou anneau dont le bord extérieur adjacent de l'âme définit une surface située (ou dont la majeure partie est située) dans le volume obtenu en prolongeant axialement la paroi extérieure du tirant au voisinage dudit appui ou située dans le volume V défini entre les bords extrêmes de deux tirants entre lesquels la poutre est fixée.According to a system according to the invention, system for connecting together beams of a structure between points of attachment of these beams on a main structure, said system comprises axial tie rods located in the extension of one another. The core of a beam is fixed between two tie rods located in the extension of one another, a first tie rod being provided with a threaded rod onto which a nut of a second tie rod is screwed, said threaded rod being engaged in a hole in the soul. The first tie is provided with a support so that the core of the beam is blocked between said support and the nut. This support or nut comprises a flange which is provided with at least one protuberance or ring whose outer edge adjacent to the core defines a surface located (or most of which is located) in the volume obtained by axially extending the outer wall of the tie rod in the vicinity of said support or located in the volume V defined between the extreme edges of two tie rods between which the beam is fixed.

De préférence, l'écrou et l'appui comprennent une bride munie d'au moins une protubérance ou anneau dont le bord extérieur adjacent de l'âme définit une surface située dans le volume obtenu en prolongeant axialement la paroi extérieure du tirant au voisinage dudit écrou ou située dans le volume défini entre les bords extrêmes des deux tirants entre lesquels la poutre est fixée.Preferably, the nut and the support comprise a flange provided with at least one protuberance or ring whose adjacent outer edge of the core defines a surface located in the volume obtained by axially extending the outer wall of the tie rod in the vicinity of said nut or located in the volume defined between the extreme edges of the two tie rods between which the beam is fixed.

Selon un autre système pour relier ensemble des poutres d'une structure entre des points de fixation de ces poutres à une structure principale, ledit système comprend des tirants axiaux s'étendant entre deux poutres ou une poutre et la structure principale, l'âme d'une poutre étant fixée à l'extrémité d'un ou de plusieurs tirants. Ladite extrémité du tirant est munie d'une tige filetée ou d'un écrou, sur laquelle un écrou d'un appui est vissé ou dans lequel est vissée une tige filetée d'un appui ou boulon, la tige filetée s'étendant à travers une ouverture ou trou que présente l'âme de la poutre, cette âme étant alors fixée entre l'appui ou boulon et l'écrou. Cet appui comprend une bride qui est munie d'au moins une protubérance ou anneau dont le bord extérieur adjacent de l'âme définit une surface située dans le volume obtenu en prolongeant axialement la paroi extérieure du tirant considéré au voisinage de la poutre, tandis que l'écrou comprend une bride qui est avantageusement munie d'au moins une protubérance ou anneau dont le bord extérieur adjacent de l'âme définit une surface située dans le volume obtenu en prolongeant axialement la paroi extérieure du tirant considéré au voisinage de la poutre.According to another system for connecting together beams of a structure between points of attachment of these beams to a main structure, said system comprises axial tie rods extending between two beams or a beam and the main structure, the core d 'a beam being attached to the end of one or more tie rods. Said end of the tie rod is provided with a threaded rod or a nut, on which a support nut is screwed or in which a threaded rod with a support or bolt is screwed, the threaded rod extending through an opening or hole that has the core of the beam, this core then being fixed between the support or bolt and the nut. This support comprises a flange which is provided with at least one protuberance or ring whose adjacent outer edge of the core defines a surface located in the volume obtained by axially extending the outer wall of the tie rod considered in the vicinity of the beam, while the nut comprises a flange which is advantageously provided with at least one protuberance or ring whose adjacent outer edge of the core defines a surface located in the volume obtained by extending axially the outer wall of the tie rod considered in the vicinity of the beam.

De façon particulièrement avantageuse, dans les systèmes selon l'invention, l'appui est une bride présentant deux protubérances circulaires ou anneaux, lesdites protubérances ou anneaux étant séparés l'un de l'autre de manière à définir entre eux une gorge. La bride de l'écrou présente également deux protubérances circulaires ou anneaux séparés l'un de l'autre de manière à définir entre eux une gorge. De tels systèmes permettent d'obtenir d'excellentes caractéristiques.In a particularly advantageous manner, in the systems according to the invention, the support is a flange having two circular protuberances or rings, said protuberances or rings being separated from each other so as to define a groove therebetween. The nut flange also has two circular protrusions or rings separated from each other so as to define a groove therebetween. Such systems make it possible to obtain excellent characteristics.

Lorsque la bride de l'appui ou de l'écrou présente une gorge s'étendant entre deux protubérances ou anneaux, l'anneau ou protubérance central ( c-à-d adjacent de l'axe du tirant considéré ) peut présenter un bord extérieur ( c-à-d éloigné de l'axe ) adjacent de l'âme de la poutre définissant une surface dont le bord extérieur n'est pas situé dans le volume défini en prolongeant axialement la paroi extérieure du tirant au voisinage de la poutre. Bien que cette forme de réalisation est avantageuse, les formes de réalisation décrites dans les paragraphes précédents semblent souvent encore plus propices, si pas préférées.When the support or nut flange has a groove extending between two protrusions or rings, the central ring or protuberance (i.e. adjacent to the axis of the tie in question) may have an outer edge (ie distant from the axis) adjacent to the core of the beam defining a surface whose outer edge is not located in the defined volume by axially extending the outer wall of the tie rod in the vicinity of the beam. Although this embodiment is advantageous, the embodiments described in the preceding paragraphs often seem even more favorable, if not preferred.

Selon une forme de réalisation avantageuse des formes de réalisation d'appui et d'écrou présentant une gorge s'étendant entre deux protubérances ou anneaux, l'appui et l'écrou sont agencés de manière à ce qu'une partie de l'appui touche une partie de l'âme de la poutre qui ne se trouve pas dans le prolongement (axial) de la partie de l'âme que touche une partie de l'écrou, tandis qu'une partie de l'écrou touche une partie de l'âme qui ne se trouve pas dans le prolongement (axial) de la partie de l'âme que touche une partie de l'appui.According to an advantageous embodiment of the embodiments of support and nut having a groove extending between two protrusions or rings, the support and the nut are arranged so that part of the support touches a part of the core of the beam which is not in the (axial) extension of the part of the core which a part of the nut touches, while a part of the nut touches a part of the core which is not in the (axial) extension of the part of the core which a part of the support touches.

Selon une autre forme de réalisation des formes de réalisation d'appui et d'écrou présentant une gorge s'étendant entre deux protubérances ou anneaux, l'appui et l'écrou sont agencés de manière à ce qu'une partie de l'appui touche une partie de l'âme qui se trouve dans le prolongement de la partie de l'âme que touche une partie de l'écrou.According to another embodiment of the support and nut embodiments having a groove extending between two protrusions or rings, the support and the nut are arranged so that part of the support touches a part of the core which is in the extension of the part of the soul touched by part of the nut.

Dans une forme particulière, l'appui comprend une bride munie de deux protubérances circulaires ou anneaux, lesdites protubérances circulaires ou anneaux étant distants l'un de l'autre pour former entre eux une gorge. L'écrou comprend une bride présentant deux protubérances circulaires ou anneaux distants l'un de l'autre pour former entre eux une gorge. Une protubérance ou anneau de l'appui ou de l'écrou se trouve dans le prolongement d'une gorge de l'écrou ou de l'appui.In a particular form, the support comprises a flange provided with two circular protuberances or rings, said circular protuberances or rings being spaced from one another to form a groove between them. The nut comprises a flange having two circular protrusions or rings spaced from each other to form a groove between them. A protuberance or ring of the support or nut is located in the extension of a groove of the nut or support.

De façon avantageuse, les brides de l'appui et de l'écrou sont munies d'ailettes, ces ailettes s'étendant de préférence entre les anneaux ou protubérances, c'est-à-dire dans les gorges.Advantageously, the flanges of the support and the nut are provided with fins, these fins preferably extending between the rings or protuberances, that is to say in the grooves.

D'autres caractéristiques et détails de l'invention ressortiront de la description détaillée suivante dans laquelle il est fait référence aux dessins ci-annexés montrant à titre d'exemple uniquement des tirants munis à ses extrémités de brides présentant une gorge s'étendant entre deux protubérances ou anneaux.Other characteristics and details of the invention will emerge from the following detailed description in which reference is made to the accompanying drawings showing by way of example only tie rods provided at its ends with flanges having a groove extending between two protrusions or rings.

La figure 1 montre en perspective une partie d'une structure d'une construction qui comprend des piliers, traverses, etc 1 sur lesquels sont attachées des poutres 2 par des moyens de fixation tels que les moyens représentés à la figure 4.FIG. 1 shows in perspective a part of a structure of a construction which includes pillars, crosspieces, etc. 1 to which beams 2 are attached by fixing means such as the means represented in FIG. 4.

Le moyen 3 représenté à la figure 4 sert pour attacher un profilé 2 en forme de Z, C ou sigma sur un montant principal 1. Le moyen 3 comprend une plaque 5 pliée le long d'un axe 7 et muni d'une gorge ou pli 6.The means 3 shown in Figure 4 is used to attach a profile 2 in the form of Z, C or sigma on a main post 1. The means 3 comprises a plate 5 folded along an axis 7 and provided with a groove or fold 6.

Le moyen 3 est fixé par exemple au moyen d'écrous ou boulons 9 sur le montant principal 1, tandis que des boulons peuvent par exemple être utilisés pour fixer le profilé en forme de Z, C ou sigma sur le moyen 3.The means 3 is fixed for example by means of nuts or bolts 9 to the main upright 1, while bolts can for example be used to fix the profile in the form of Z, C or sigma on the means 3.

Entre des points de fixation 3 des poutres 2 sur les piliers ou traverses 1, se trouvent des systèmes 10,11 selon l'invention.Between fixing points 3 of the beams 2 on the pillars or crosspieces 1, are systems 10, 11 according to the invention.

Le système 10 comprend des tirants 10A, 10B, etc qui sont placés dans le prolongement l'un de l'autre. Entre les tirants 10A et 10B est fixée l'âme 30 du profilé 2 par exemple en forme de C (voir figure 2).The system 10 comprises tie rods 10A, 10B, etc. which are placed in the extension of one another. Between the tie rods 10A and 10B is fixed the core 30 of the profile 2, for example in the form of C (see FIG. 2).

Une extrémité du tirant 10A est munie d'une tige filetée 12 sur laquelle l'écrou 13 d'une extrémité du tirant 10B est vissé. La tige filetée 12 traverse l'âme 30 de la poutre 2 par une ouverture 14.One end of the tie rod 10A is provided with a threaded rod 12 on which the nut 13 of one end of the tie rod 10B is screwed. The threaded rod 12 passes through the core 30 of the beam 2 through an opening 14.

Grâce au vissage de la tige filetée 12 dans l'écrou 13, l'âme 30 de la poutre 2 est fixée, coincée ou comprimée entre un appui 15 du tirant 10A et l'écrou 13 du tirant 10B.Thanks to the screwing of the threaded rod 12 in the nut 13, the core 30 of the beam 2 is fixed, wedged or compressed between a support 15 of the tie rod 10A and the nut 13 of the tie rod 10B.

L'appui 15 comprend dans la forme de réalisation représentée qui est une des formes préférées, une bride 16 comprenant deux anneaux 17,18 entre lesquels est définie une gorge 19. Dans la gorge 19 et entre les anneaux 17,18 s'étendent des ailettes 20 (ailettes reliant les anneaux 17,18) pour accroître encore la rigidité de la bride. Cette bride, ailettes et anneaux sont par exemple réalisés en une matière synthétique, par exemple en polyamide armé (fibre de verre).The support 15 comprises in the embodiment shown which is one of the preferred forms, a flange 16 comprising two rings 17,18 between which is defined a groove 19. In the groove 19 and between the rings 17,18 extend fins 20 (fins connecting the rings 17,18) to increase still the stiffness of the flange. This flange, fins and rings are for example made of a synthetic material, for example reinforced polyamide (fiberglass).

L'écrou 13 est, dans la forme de réalisation représentée, également muni d'une bride 16 avec deux anneaux 17,18 entre lesquels une gorge 19 est définie et qui sont reliés l'un à l'autre par des ailettes 20 s'étendant dans la gorge 19.The nut 13 is, in the embodiment shown, also provided with a flange 16 with two rings 17,18 between which a groove 19 is defined and which are connected to each other by fins 20 s' extending into the throat 19.

Dans cette forme de réalisation, l'appui 15 et l'écrou 13 sont agencés de manière telle que les parties de l'âme 30 que touchent les anneaux 17,18 de l'appui 15 sont dans le prolongement (direction de l'axe X du tirant) des parties de l'âme 30 que touchent les anneaux 17,18 de l'écrou 13.In this embodiment, the support 15 and the nut 13 are arranged in such a way that the parts of the core 30 that touch the rings 17, 18 of the support 15 are in the extension (direction of the axis X of the tie rod) of the parts of the core 30 that the rings 17, 18 of the nut 13 touch.

Comme on le remarquera, les anneaux 17 de l'appui 15 et de l'écrou 13 présentent un bord 17A adjacent de l'âme 30 de la poutre et dirigée vers l'anneau 18 (c'est-à-dire éloigné de l'axe X), qui définit une surface située dans le volume V obtenu en prolongeant dans la direction axiale X la paroi extérieure des tirants 10A, 10B, c'est-à-dire dans le cas représenté dans le volume V défini entre le bord extrême (100) de la paroi extérieure du tirant 10A (bord tourné vers l'âme 30) et le bord extrême (101) de la paroi extérieure du tirant 10B (bord tourné vers l'âme 30).As will be noted, the rings 17 of the support 15 and of the nut 13 have an edge 17A adjacent to the core 30 of the beam and directed towards the ring 18 (that is to say distant from the 'axis X), which defines a surface located in the volume V obtained by extending in the axial direction X the outer wall of the tie rods 10A, 10B, that is to say in the case shown in the volume V defined between the edge end (100) of the outer wall of the tie rod 10A (edge facing the core 30) and the end edge (101) of the outer wall of the tie rod 10B (edge facing the core 30).

La surface définie par ledit bord 17a est avantageusement éloignée d'une distance de 1 mm, de préférence d'au moins 2 mm, en particulier de 3 à 5 mm de la surface extérieure dudit volume.The surface defined by said edge 17a is advantageously distant from a distance of 1 mm, preferably at least 2 mm, in particular from 3 to 5 mm from the external surface of said volume.

Les ailettes 20 ont avantageusement une surface supérieure qui initialement ne correspond pas à la surface supérieure de l'anneau 17, ni à la surface supérieure de l'anneau 18 (surface supérieure des ailettes légèrement en retrait par rapport aux surfaces supérieures des anneaux 17,18, avant montage). Après montage, ces surfaces supérieures s'étendent avantageusement dans un même plan W. Ces ailettes 20 forment en quelque sorte des doigts solidaires de l'anneau central 17, ledit anneau central s'étendant dans le volume V défini en prolongeant axialement la paroi extérieure du tirant, tandis que lesdites ailettes s'étendent hors dudit volume V.The fins 20 advantageously have an upper surface which initially does not correspond to the upper surface of the ring 17, nor to the upper surface of the ring 18 (upper surface of the fins slightly set back from the upper surfaces of the rings 17,18, before mounting). After mounting, these upper surfaces advantageously extend in the same plane W. These fins 20 somehow form fingers integral with the central ring 17, said central ring extending in the volume V defined by axially extending the outer wall of the tie rod, while said fins extend out of said volume V.

On a remarqué qu'en utilisant un tel système, le desserrage ou dévissage de la tige filetée était difficile et que le système présentait une excellente résistance à la flexion.It has been noted that using such a system, loosening or unscrewing the threaded rod was difficult and that the system exhibited excellent resistance to bending.

L'écrou 13 et l'appui 15 sont constitués d'un élément qui est montré à la figure 5. Cet élément 21 a une forme sensiblement cylindrique et présente à ses deux extrémités un évidement 22,23. L'évidement 22 est muni d'un filet sur lequel l'extrémité d'une tige filetée peut être vissée pour la fixer. L'évidement 23 est muni d'ailettes 24 pour accroître la rigidité de l'élément.The nut 13 and the support 15 consist of an element which is shown in FIG. 5. This element 21 has a substantially cylindrical shape and has at its two ends a recess 22, 23. The recess 22 is provided with a thread on which the end of a threaded rod can be screwed to fix it. The recess 23 is provided with fins 24 to increase the rigidity of the element.

L'élément présente une gorge annulaire 25 qui sert à fixer l'élément 21 à une extrémité d'une buse ou tuyau 26. Par déformation de la buse ou tuyau, l'élément 21 ne peut plus glisser dans la direction axiale ou longitudinale X de la buse 26.The element has an annular groove 25 which serves to fix the element 21 to one end of a nozzle or pipe 26. By deformation of the nozzle or pipe, the element 21 can no longer slide in the axial or longitudinal direction X from nozzle 26.

L'extrémité 27 de l'élément 21 qui est engagée dans le tuyau ou buse présente un bord effilé pour faciliter le placement ou montage de l'élément 21 dans ledit tuyau ou buse 26.The end 27 of the element 21 which is engaged in the pipe or nozzle has a tapered edge to facilitate the placement or mounting of the element 21 in said pipe or nozzle 26.

L'élément est avantageusement réalisé en matière synthétique.The element is advantageously made of synthetic material.

Pour éviter une éventuelle rotation de l'élément par rapport à la buse, la buse 26 est munie par exemple dans le sens de sa longueur (X) d'une ou de plusieurs protubérances intérieures 28. Lors de l'engagement de l'élément 21 dans la buse 26, au moins une protubérance est enfoncée dans l'élément.To avoid possible rotation of the element relative to the nozzle, the nozzle 26 is provided for example in the direction of its length (X) with one or several interior protuberances 28. When the element 21 is engaged in the nozzle 26, at least one protuberance is pressed into the element.

L'extrémité 29 de l'élément 21 porte la bride 16, les anneaux 17,18 et les ailettes 20.The end 29 of the element 21 carries the flange 16, the rings 17,18 and the fins 20.

La figure 3 montre une autre forme de réalisation d'un système suivant l'invention (Détail B de la figure 1).Figure 3 shows another embodiment of a system according to the invention (Detail B of Figure 1).

La poutre 2 est constituée à titre d'exemple d'un profilé du type sigma qui est muni aux extrémités de l'âme 30 d'un rebord 31. Ce rebord 31 comprend une lèvre qui est pliée de manière telle que les extrémités sont tournées vers le plan V de l'âme 30.The beam 2 consists for example of a sigma type profile which is provided at the ends of the core 30 with a flange 31. This flange 31 comprises a lip which is folded in such a way that the ends are turned towards plane V of the core 30.

Ce rebord 31 est constitué

  • d'un plat supérieur ou inférieur 32 qui s'étend dans le plan P qui est perpendiculaire au plan V de l'âme 30, ledit plan V de l'âme 30 traversant ou coupant ladite plaque supérieure ou inférieure 32;
  • deux plats 33,34 qui sont chacun reliés à une extrémité du plat supérieur ou inférieur et qui s'étendent dans un plan qui est parallèle au plan V de l'âme 30 ;
  • un plat 35 qui prolonge le plat 34, qui s'étend dans un plan perpendiculaire au plan V de l'âme 30 et qui est tourné vers le plat 33 ou vers l'âme, et
  • un plat 36 qui relie le plat 33 avec l'âme 30 et qui s'étend dans un plan incliné par rapport au plan V de l'âme 30.
This rim 31 is constituted
  • an upper or lower plate 32 which extends in the plane P which is perpendicular to the plane V of the core 30, said plane V of the core 30 passing through or cutting said upper or lower plate 32;
  • two plates 33, 34 which are each connected to one end of the upper or lower plate and which extend in a plane which is parallel to the plane V of the core 30;
  • a dish 35 which extends the dish 34, which extends in a plane perpendicular to the plane V of the core 30 and which is turned towards the dish 33 or towards the core, and
  • a plate 36 which connects the plate 33 with the core 30 and which extends in a plane inclined with respect to the plane V of the core 30.

Un tel profilé présente de nombreux avantages, dont entre autres, meilleure rigidité, meilleure résistance pour une hauteur maximale déterminée, les bords du profilé ne sont pas visibles, élimination du risque de blessures pour l'utilisateur lors de la manipulation, etc.Such a profile has many advantages, including, among other things, better rigidity, better resistance for a determined maximum height, the edges of the profile are not visible, elimination of the risk of injury to the user during handling, etc.

Par rapport à la forme de réalisation de la figure 2, l'appui 15 du tirant 11A présente une bride ou rebord 16 de diamètre plus important que la bride ou rebord 16 de l'écrou 13.Compared to the embodiment of FIG. 2, the support 15 of the tie rod 11A has a flange or flange 16 of larger diameter than the flange or flange 16 of the nut 13.

Dans cette forme de réalisation, les anneaux 17 touchent des parties de l'âme 30 qui se trouvent dans le prolongement l'une de l'autre (par rapport à l'axe X des tirants 11A et 11B). L'anneau 18 de l'écrou 13 touche une partie de l'âme 30 qui ne se trouve pas dans le prolongement de la partie de l'âme 30 que touche l'anneau 18 de l'appui 15. L'anneau 18 de l'écrou 13 se trouve en fait dans le prolongement de la gorge 19 de l'appui 15 (gorge 19 qui est munie d'ailettes 20). Cette forme de réalisation semble être excellente en ce qui concerne sa rigidité à la flexion, mais aussi en ce qui concerne l'absence de risque de desserrage.In this embodiment, the rings 17 touch parts of the core 30 which are in line with one another (relative to the X axis of the tie rods 11A and 11B). The ring 18 of the nut 13 touches a part of the core 30 which is not in the extension of the part of the core 30 that the ring 18 of the support touches. The ring 18 of the nut 13 is in fact in the extension of the groove 19 of the support 15 (groove 19 which is provided with fins 20). This embodiment seems to be excellent as regards its flexural rigidity, but also as regards the absence of risk of loosening.

Enfin, le figure 10 montre une autre forme de réalisation d'un tirant qui peut être utilisé. Ce tirant est similaire au tirant représenté à la figure 2, si ce n'est que la gorge 19 n'est pas munie d'ailettes. Les ailettes 20 sont placées sur la face de la bride 16 opposée à la face portant les anneaux 17 et 18.Finally, Figure 10 shows another embodiment of a tie rod which can be used. This tie is similar to the tie shown in Figure 2, except that the groove 19 is not provided with fins. The fins 20 are placed on the face of the flange 16 opposite the face carrying the rings 17 and 18.

Aux extrémités d'un tirant ou d'une série de tirants vissés entre eux, la première poutre et la dernière poutre sont fixées au moyen d'un boulon et d'un anneau ou rondelle, qui est vissé dans le filet des extrémités libres des tirants extrêmes.At the ends of a tie rod or a series of tie rods screwed together, the first beam and the last beam are fixed by means of a bolt and a ring or washer, which is screwed into the thread of the free ends of the extreme tie rods.

La figure 11 présente un système pour relier deux poutres, des tirants 10 s'étendant entre la poutre 2A et la poutre 2B.Figure 11 shows a system for connecting two beams, tie rods 10 extending between the beam 2A and the beam 2B.

Dans la forme de réalisation représentée, le tirant 10 est muni à ses deux extrémités d'un écrou 13 dont la gorge n'est pas munie d'ailettes. Les ailettes 20 sont placées sur la face de la bride 16 opposée à la face portant les anneaux 17 et 18.In the embodiment shown, the tie rod 10 is provided at its two ends with a nut 13, the groove of which is not provided with fins. The fins 20 are placed on the face of the flange 16 opposite the face carrying the rings 17 and 18.

Aux extrémités d'un tirant ou d'une série de tirants vissés entre eux, la première poutre et la dernière poutre sont fixées au moyen d'un boulon et d'un anneau ou rondelle, qui est vissé dans le filet des extrémités libres des tirants extrêmes.At the ends of a tie rod or a series of tie rods screwed together, the first beam and the last beam are fixed by means of a bolt and a ring or washer, which is screwed into the thread of the free ends of the extreme tie rods.

La figure 11 présente un système pour relier deux poutres, des tirants 10 s'étendant entre la poutre 2A et la poutre 2B.Figure 11 shows a system for connecting two beams, tie rods 10 extending between the beam 2A and the beam 2B.

Dans la forme de réalisation représentée, le tirant 10 est muni à ses deux extrémités d'un écrou 13 dans lequel une tige filetée peut être vissée. Le tirant peut éventuellement être muni de tiges filetées 12.In the embodiment shown, the tie rod 10 is provided at its two ends with a nut 13 into which a threaded rod can be screwed. The tie rod may possibly be fitted with threaded rods 12.

La tige filetée 12 d'un boulon est vissée dans l'écrou 13, de sorte que l'âme 30 du profilé 2B est fixée ou coincée entre l'appui 15 avec ou sans bride 16 et la bride 16 de l'écrou 13 du tirant. Ainsi que représenté aux figures 5 à 9, l'appui et/ou l'écrou sont munis d'une bride portant deux anneaux 17,18. Ces anneaux sont écartés l'un de l'autre pour former entre eux une gorge 19 dans laquelle s'étendent des ailettes.The threaded rod 12 of a bolt is screwed into the nut 13, so that the core 30 of the profile 2B is fixed or wedged between the support 15 with or without flange 16 and the flange 16 of the nut 13 of the pulling. As shown in Figures 5 to 9, the support and / or the nut are provided with a flange carrying two rings 17,18. These rings are spaced from each other to form between them a groove 19 in which the fins extend.

Dans la forme de réalisation représentée, l'âme 30 de la poutre 2A est fixée entre la bride 16 qui travaille avec un boulon 15 et une bride de l'écrou 13, tandis que l'âme 30 de la poutre 2B est fixée entre le boulon 15 (sans bride 16) et une bride 16 solidaire du tirant 10.In the embodiment shown, the core 30 of the beam 2A is fixed between the flange 16 which works with a bolt 15 and a flange of the nut 13, while the core 30 of the beam 2B is fixed between the bolt 15 (without flange 16) and a flange 16 secured to the tie rod 10.
