Description

La présente invention concerne un dispositif d'as­semblage d'un arbalétrier de ferme avec un poteau, pour la réalisation de charpentes, et plus généralement de structu­res.The present invention relates to a device for assembling a farm crossbowman with a pole, for the production of frames, and more generally of structures.

Actuellement, pour la réalisation d'une charpente ou d'une structure, l'assemblage de l'arbalétrier de ferme avec chaque poteau de soutien ne peut se faire que grâce à différents éléments de serrage tels que boulons, goujons, vis, broches etc..., et à l'aide de pièces de liaison non moulées.Currently, for the realization of a frame or structure, the assembly of the farm crossbowman with each support post can only be done thanks to different clamping elements such as bolts, studs, screws, pins etc. ..., and using non-molded connecting pieces.

Il est donc nécessaire, pour effectuer un tel as­semblage, de recourir à un outillage complet et, le cas échéant, de réaliser cette opération à plusieurs personnes, afin de positionner exactement les pièces de liaison simul­tanément sur l'arbalétrier et sur le poteau. Un tel montage nécessite donc un temps considérable et un investissement en matériel et en hommes relativement important. De plus, les pièces de liaison augmentent le poids de la charpente ou de la structure, ainsi d'ailleurs que son volume, les pièces de liaison n'étant incluses que partiellement dans l'arba­létrier ou dans le poteau, ce qui pose des problèmes tant au stockage qu'au chargement. Par ailleurs, il arrive qu'au montage, certaines pièces de liaison ou autres fassent dé­faut, ce qui entraîne inévitablement une perte de temps, et très souvent des problèmes au niveau de la sécurité, car il n'est pas rare que les monteurs, dans le souci de progresser rapidement, ne remplacent la pièce défaillante par une pièce destinée à un autre usage.It is therefore necessary, to carry out such an assembly, to have recourse to a complete tooling and, if necessary, to carry out this operation with several people, in order to exactly position the connecting pieces simultaneously on the crossbowman and on the post. Such an assembly therefore requires considerable time and a relatively large investment in equipment and men. In addition, the connecting pieces increase the weight of the frame or structure, as well as its volume, the connecting pieces being only partially included in the crossbowman or in the post, which poses problems. both during storage and loading. In addition, it happens that during assembly, some connecting parts or others fail, which inevitably leads to a loss of time, and very often problems in terms of safety, because it is not uncommon for fitters, in order to progress quickly, do not replace the faulty part with a part intended for another use.

Le problème général à résoudre par l'objet de la présente demande, est de réaliser un dispositif d assemblage dans lequel aucune pièce de liaison ni aucun élément de ser­rage n'intervient. Par ailleurs, ce dispositif doit étre le plus léger et le moins volumineux possible (afin de permet­tre un stockage et un chargement aisé), tout en présentant une sûreté suffisante au levage, chaque arbalétrier de la ferme étant généralement assemblé avec le poteau à même le sol, l'ensemble étant ensuite levé.The general problem to be solved by the subject of the present application is to produce an assembly device in which no connecting piece or any clamping element intervenes. Furthermore, this device must be as light and as bulky as possible (in order to allow easy storage and loading), while having sufficient safety when lifting, each crossbowman on the farm is generally assembled with the pole on the ground, the assembly then being lifted.

Un tel dispositif devra permettre à une seule personne de réaliser l'assemblage de l'arbalétrier avec cha­que poteau sans aucun outillage (plus de risque de perte, simplification, économie de matériel...), et sans aucune pièce de liaison à fixer lors de l'assemblage afin de rendre l'ensemble plus sûr, d'entraîner une simplification de mon­tage ainsi qu'un gain de temps substantiel. Enfin tous ces paramètres concourent, bien entendu, à rendre un tel mode d'assemble bien plus économique que les modes d'assemblage actuels.Such a device should allow a single person to assemble the crossbowman with each pole without any tools (more risk of loss, simplification, saving material ...), and without any connecting piece to be fixed during of the assembly in order to make the assembly safer, to lead to a simplification of assembly as well as a substantial saving of time. Finally, all these parameters combine, of course, to make such an assembly method much more economical than current assembly methods.

Selon la présente invention, le dispositif d'as­semblage d'un arbalétrier de ferme avec un poteau, pour la réalisation de charpentes et structures, est caractérisé en ce qu'il consiste en deux pièces moulées, l'une étant dispo­sée, de manière fixe, à l'intérieur de l'extrémité inférieu­re de l'arbalétrier, et l'autre étant disposée, de manière fixe, partiellement à l'intérieur de l'extrémité supérieure du poteau, les deux pièces coopérant entre elles en vue d'assurer l'assemblage et la fixation de l'arbalétrier avec le poteau par simple emboîtement.According to the present invention, the device for assembling a farm crossbowman with a pole, for the production of frames and structures, is characterized in that it consists of two molded parts, one being arranged, fixedly , inside the lower end of the crossbowman, and the other being disposed, in a fixed manner, partially inside the upper end of the post, the two parts cooperating with each other in order to ensure assembling and fixing the crossbowman with the post by simple interlocking.

L'invention sera mieux comprise grâce à la des­cription ci-après, qui se rapporte à un mode de réalisa­tion préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue, de face, d'une structure composée d'une ferme et de différents poteaux de soutien ;
  • la figure 2 est une vue, de face, à plus grande échelle que la figure 1, d'un dispositif d'assemblage conforme à l'invention et reliant un arbalétrier avec un poteau ;
  • la figure 3 est une vue, en coupe, à plus grande échelle que la figure 2, et selon la ligne A-A de la figure 2 ;
  • la figure 4 est une vue, en coupe, à même échelle que la figure 3, et selon la ligne B-B de la figure 2, et
  • la figure 5 est une vue, en coupe, à même échelle que les figures 3 et 4, et selon la ligne C-C de la figure 2.
The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a front view of a structure composed of a truss and various support posts;
  • Figure 2 is a front view, on a larger scale than Figure 1, of an assembly device according to the invention and connecting a crossbowman with a pole;
  • Figure 3 is a sectional view, on a larger scale than Figure 2, and along the line AA of Figure 2;
  • FIG. 4 is a view, in section, on the same scale as FIG. 3, and along the line BB of FIG. 2, and
  • FIG. 5 is a view, in section, on the same scale as the Figures 3 and 4, and along line CC of Figure 2.

Conformément à l'invention, le dispositif d'assem­blage consiste en deux pièces moulées 1 et 2, l'une 1 étant disposée, de manière fixe, à l'intérieur de l'extrémité inférieure de l'arbalétrier 3, et l'autre 2 étant disposée, de manière fixe, partiellement à l'intérieur de l'extrémité supérieure du poteau 4, les deux pièces 1 et 2 coopérant entre elles en vue d'assurer l'assemblage et la fixation de l'arbalétrier 3 avec le poteau 4 par simple emboîtement.According to the invention, the assembly device consists of two molded parts 1 and 2, one 1 being fixedly disposed inside the lower end of the crossbowman 3, and the other 2 being disposed, fixedly, partially inside the upper end of the pole 4, the two parts 1 and 2 cooperating with each other in order to ensure the assembly and the fixing of the crossbowman 3 with the pole 4 by simple interlocking.

Selon une première caractéristique de l'invention, la pièce moulée 1 comporte deux encoches 5 et 6, et la pièce moulée 2 deux ergots 7 et 8, l'assemblage de l'arbalétrier 3 avec le poteau 4 s'effectuant exclusivement par emboîtement des deux ergots 7 et 8 dans les deux encoches 5 et 6.According to a first characteristic of the invention, the molded part 1 comprises two notches 5 and 6, and the molded part 2 two lugs 7 and 8, the assembly of the crossbowman 3 with the post 4 being effected exclusively by interlocking the two pins 7 and 8 in the two notches 5 and 6.

Comme on peut le voir sur la figure 2, l'emboîte­ment ergot 7 - encoche 5 est séparé de l'autre emboîtement ergot 8 - encoche 6 d'une distance supérieure à la section du poteau 4.As can be seen in FIG. 2, the lug socket 7 - notch 5 is separated from the other lug socket 8 - notch 6 by a distance greater than the section of the post 4.

Ceci permet d'assurer une rigidité et une résis­tance optimales pour chaque assemblage.This ensures optimum rigidity and strength for each assembly.

Conformément aux figures 2 à 5, chaque pièce mou­lée 1 ou 2 comprend différents bossages 9 permettant de maintenir les pièces moulées 1 et 2 dans l'arbalétrier 3 ou le poteau 4, la longueur de ces bossages 9 correspondant sensiblement à la section interne de l'arbalétrier 3 ou du poteau 4. Ces bossages 9 servent de support à un ensemble de fixation, par exemple, vis 10 - écrou 11, la vis 10 traversant le bossage 9, par un orifice 20, ces bossages 9 étant, par ailleurs, reliés entre eux par un voile 14 situé dans le plan perpendiculaire aux axes centraux des bossages 9 et passant par l'axe de symétrie A de chaque pièce moulée 1 ou 2, et par des nervures 19 situées, par exemple, dans le plan passant par les axes centraux des bossages 9.In accordance with FIGS. 2 to 5, each molded part 1 or 2 comprises different bosses 9 making it possible to hold the molded parts 1 and 2 in the crossbowman 3 or the post 4, the length of these bosses 9 corresponding substantially to the internal section of the 'crossbowman 3 or pole 4. These bosses 9 serve as a support for a fixing assembly, for example, screw 10 - nut 11, the screw 10 passing through the boss 9, through an orifice 20, these bosses 9 being, moreover, interconnected by a web 14 located in the plane perpendicular to the central axes of the bosses 9 and passing through the axis of symmetry A of each molded part 1 or 2, and by ribs 19 located, for example, in the plane passing through the central axes of the bosses 9.

Préalablement donc, par exemple immédiatement après la fabrication des arbalétriers 3 et des poteaux 4, il y a lieu d'insérer à l'intérieur de l'extrémité supérieure de chaque poteau 4, une pièce moulée 2 et à l'intérieur de l'extrémité inférieure de chaque arbalétrier 3, une pièce moulée 1. Puis, ces pièces moulées 1 et 2 seront fixées à l'intérieur respectivement de chaque arbalétrier 3 et de chaque poteau 4 à l'aide de tous moyens connus tels que boulons, goujons, vis, broches, etc...Beforehand therefore, for example immediately after the manufacture of the rafters 3 and the posts 4, it is necessary to insert inside the upper end of each post 4, a molded part 2 and inside the lower end of each crossbowman 3, one piece molded 1. Then, these molded parts 1 and 2 will be fixed inside respectively of each crossbowman 3 and each post 4 using any known means such as bolts, studs, screws, pins, etc ...

Lors de l'utilisation de ces arbalétriers 3 et po­teaux 4, ceux-ci se trouvent donc déjà pourvus de pièces moulées 1 et 2.When these rafters 3 and posts 4 are used, they are therefore already provided with molded parts 1 and 2.

Il ne suffit alors plus, pour les assembler, que d'emboîter les ergots 7 et 8 dans les encoches 5 et 6 des deux pièces moulées 1 et 2. Ceci est rendu possible grâce à un évidement opéré à l'extrémité inférieure de l'arba­létrier 3.In order to assemble them, it then suffices only to fit the lugs 7 and 8 into the notches 5 and 6 of the two molded parts 1 and 2. This is made possible by a recess operated at the lower end of the crossbowman 3.

Un tel assemblage suffit à rendre l'opération de levage de la ferme assemblée au sol, parfaitement sûre, la distance séparant les deux emboîtements étant suffisante pour assurer une stabilité parfaite à l'ensemble et les bos­sages 9 reprenant pratiquement tous les efforts lors de l'opération de levage elle-même.Such an assembly is sufficient to make the lifting operation of the farm assembled on the ground, perfectly safe, the distance separating the two interlockings being sufficient to ensure perfect stability for the assembly and the bosses 9 taking up practically all the forces during the lifting operation itself.

Par ailleurs, on peut constater que la pièce mou­lée 1 est entièrement située à l'intérieur de l'arbalétrier 3, la pièce moulée 2, quant à elle, l'étant sur pratiquement toute sa longueur, seule l'extrémité supérieure de la pièce moulée 2 dépassant légèrement du poteau 4. Une telle struc­ture présente l'avantage de pouvoir être stockée et trans­portée très facilement.Furthermore, it can be seen that the molded part 1 is entirely located inside the crossbowman 3, the molded part 2, for its part, being over practically its entire length, only the upper end of the part. molded 2 slightly protruding from the post 4. Such a structure has the advantage of being able to be stored and transported very easily.

Enfin, la structure des pièces moulées 1, 2 elle-­meme (voile 14, nervures 19) a été conçue en vue d'obtenir des pièces moulées 1, 2 les plus légères possibles. Celles-­ci pourront être avantageusement en alliage léger, par exem­ple en aluminium.Finally, the structure of the molded parts 1, 2 itself (web 14, ribs 19) was designed to obtain the lightest possible molded parts 1, 2. These could advantageously be made of light alloy, for example aluminum.

Selon une variante de l'invention, et comme le montre la figure 2, la pièce moulée 1 peut être pourvue, à l'une de ses extrémités, d'un étrier 12 permettant la fixa­tion éventuelle d'un prolongement 13 à l'arbalétrier 3 par tous moyens connus, tels que des ensembles vis 10 - écrou 11, chaque vis 10 étant alors supportée par un bossage 9 si­tué sur l'étrier 12.According to a variant of the invention, and as shown in FIG. 2, the molded part 1 can be provided, at one of its ends, with a stirrup 12 allowing the possible fixing of an extension 13 to the crossbowman 3 by any known means, such as screw 10 - nut 11 assemblies, each screw 10 then being supported by a boss 9 located on the stirrup 12.

Un tel étrier 12 permet, en cas d'extension d'un bâtiment, de prolonger l'arbalétrier 3, ce prolongement 13 pouvant lui-même être, bien entendu, pourvu à son autre extrémité d'une pièce moulée 1 permettant son assemblage à un poteau 4 (voir figure 1 des dessins annexés).Such a stirrup 12 allows, in case of extension of a building, to extend the crossbowman 3, this extension 13 which can itself be, of course, provided at its other end with a molded part 1 allowing its assembly to a post 4 (see Figure 1 of the accompanying drawings).

Par ailleurs, on peut également prévoir que dans cet étrier 12 coulisse le système de tension de bâches d'une ferme à l'autre.Furthermore, it can also be provided that in this stirrup 12 slides the sheet tensioning system from one farm to another.

Conformément à une seconde variante de l'inven­tion, et comme le montre également la figure 2, le disposi­tif d'assemblage peut, en outre, être pourvu d'un dispositif de verrouillage automatique de sécurité 15, sous la forme d'un ergot 16 monté sur ressort 17 situé sur la pièce moulée 1, et venant coopérer avec une encoche 18 située sur la piè­ce moulée 2.In accordance with a second variant of the invention, and as also shown in FIG. 2, the assembly device can, in addition, be provided with an automatic safety locking device 15, in the form of a lug 16 mounted on spring 17 located on the molded part 1, and coming to cooperate with a notch 18 located on the molded part 2.

Le ressort 17 permet d'assurer un verrouillage au­tomatique sitôt que l'ergot 16 rencontre l'encoche 18 de la pièce moulée 2.The spring 17 ensures automatic locking as soon as the lug 16 meets the notch 18 of the molded part 2.

Enfin, et selon une dernière variante de l'inven­tion, la pièce moulée 1 peut être pourvue d'un bossage 9′ dont l'axe central est parallèle aux autres bossages 9 et permettant le passage des câbles de contreventement (figure 2).Finally, and according to a last variant of the invention, the molded part 1 can be provided with a boss 9 ′ whose central axis is parallel to the other bosses 9 and allowing the passage of the bracing cables (Figure 2).

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins an­nexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour au­tant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
