Abstract
Description
La présente invention se rapporte å l'assemblage d'eléments tubulaires bout à bout plus particulièrement destinés à réaliser des tours d'étaiement. The present invention relates to the assembly of tubular elements end to end more particularly intended to make shoring towers.
Pour certains travaux, on réalise des tours d'étaiement comprenant des poteaux verticaux reliés entre eux par des entretoises pour donner une bonne rigidité à l'ensemble. Chaque poteau est constitué d'une série d'éléments tubulaires assemblés bout à bout pour qu'on puisse réaliser des tours ayant des hauteurs correspondant a la hauteur de l'ouvrage à étayer. For certain works, shoring towers are carried out comprising vertical posts connected together by spacers to give good rigidity to the assembly. Each post consists of a series of tubular elements assembled end to end so that towers can be made having heights corresponding to the height of the structure to be shored.
Ces tours doivent constituer une structure parfaitement rigide susceptible de supporter des contraintes importantes et on conçoit donc que l'assemblage des éléments tubulaires bout a bout doit être sans défaillance, d'autant plus que ces tours sont, souvent, montées en dehors de l'ouvrage a étayer et mises en place a l'aide de grues et souvent dégagées ensuite avec ces engins de levage. On a constaté que, malheucreusement, l'assemblage des éléments bout a bout n'était pas toujours parfait et qu'il subsistait des risques de voir des éléments se détacher au cours de la mise en place, avec les dangers que cela peut entrainer pour le personnel. Egalement si certains éléments ne sont pas parfaitement assembles, on peut craindre que l'étayage ne présente plus la resistance mécanique suffisante pour soutenir l'ouvrage a étayer. These towers must constitute a perfectly rigid structure capable of withstanding significant stresses and it is therefore understandable that the assembly of the tubular elements end to end must be without failure, all the more since these towers are, often, mounted outside the structure to be propped up and put in place with the help of cranes and often freed afterwards with these lifting devices. It was noted that, unfortunately, the assembly of the elements end to end was not always perfect and that there remained risks of seeing elements detach during the installation, with the dangers that this can entail for the staff. Also if certain elements are not perfectly assembled, it is feared that the shoring no longer has sufficient mechanical strength to support the structure to be shored.
L'invention a pour but de réaliser un assemblage qui soit simple, robuste, qui assure un verrouillage automatique des éléments entre eux, sans avoir recours à des outils et qui offre une grande sécurité. The object of the invention is to produce an assembly which is simple, robust, which ensures automatic locking of the elements together, without the need for tools and which offers great security.
Les perfectionnements objet de l'invention s'appliquent a l'assemblage bout a bout de barres ou d'éléments tubulaires comprenant une extrémité male et une extrémité femelle de maniere qu'on puisse assembler plusieurs éléments par l'engagement de l'extrémité mdle dans l'extrémité femelle correspondante -d'un autre élément, et sont caractérisés en ce que l'extrémité màle comporte au moins une saillie latérale, tandis que l'extrémité femelle comporte, sur son bord libre, une fente allongée sensiblement longitudinalement et dans laquelle peut s'engager la saillie, l'un des bords de la fente comportant, en un point intermédiaire de sa longueur, une entaille d'une dimension suffisante pour permettre l'engagement de ladite saillie, sur l'extrémité femelle étant montée coulissante une bague comportant un doigt de verrouillage mobile dans la fente et dont les débattements sont limités par une butée, le doigt et ladite fente ayant des dimensions telles que, lors de l'introduction de la saillie dans ladite fente, le doigt soit repoussé pour permettre à la saillie d'être introduite dans l'entaille, ledit doigt s'opposant ensuite au dégagement de la saillie de ltentaille. The improvements which are the subject of the invention apply to the end-to-end assembly of bars or tubular elements comprising a male end and a female end so that several elements can be assembled by engaging the male end. in the corresponding female end - of another element, and are characterized in that the male end comprises at least one lateral projection, while the female end comprises, on its free edge, an elongated slot substantially longitudinally and in which can engage the projection, one of the edges of the slot having, at an intermediate point of its length, a notch of sufficient size to allow the engagement of said projection, on the female end being slidably mounted a ring comprising a movable locking finger in the slot and whose deflections are limited by a stop, the finger and said slot having dimensions such that, during the introduction of the projection in said slot, the finger is pushed back to allow the projection to be introduced into the notch, said finger then opposing the release of the projection from the notch.
Grâce à cette disposition, on realise un assemblage simple et particulièrement efficace, le doigt assurant un verrouillage automatique. Thanks to this arrangement, a simple and particularly efficient assembly is carried out, the finger ensuring automatic locking.
Suivant une caractéristique constructive particu lière, l'extrémité mâle comporte deux saillies décalées angulairement de I80", l'extrémité femelle comportant deux fentes décalées angulairement de 1800 et la bague étant pourvue de deux doigts correspondants. According to a particular constructive characteristic, the male end comprises two projections offset angularly by 180 ", the female end comprising two slots offset angularly by 1800 and the ring being provided with two corresponding fingers.
De préférence, la saillie est constituée d'une pièce 'rapportée soudée latéralement au voisinage de l'extrémité correspondante de l'élément et affectant une forme générale rectangulaire dont un grand côté longitudinal- constitue un bord de guidage, tandis que l'autre grand côté comporte une encoche pour former une languette destinée à s'engager dans l'entaille de I'extrémité femelle. Preferably, the projection consists of an attached piece welded laterally in the vicinity of the corresponding end of the element and having a generally rectangular shape, a large longitudinal side of which constitutes a guide edge, while the other large side has a notch to form a tongue intended to engage in the notch of the female end.
Enfin, suivant une derniere caractéristique, la butée limitant les débattemnts de la bague est constituée par un anneau soudé sur le bord libre de l'extrémité femelle. Finally, according to a last characteristic, the stop limiting the deflections of the ring is constituted by a ring welded on the free edge of the female end.
L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et reprisent, eux dessins annexes. The invention will now be described in more detail with reference to a particular embodiment given by way of example only and reproduce them annexed drawings.

Fig. 2 est une vue en élévation des extrémites montees,
Fig. 3 est une vue en perspective éclate montrant l'assemblage d'une extremite mâle dans une extrémité femelle.Fig. I is an elevational view of a tubular element intended for the production of a shoring tower,
Fig. 2 is an elevation view of the mounted ends,
Fig. 3 is an exploded perspective view showing the assembly of a male end in a female end.
Chaque élément tubulaire I comporte une extrémité mâle 2 et une extremite opposée femelle 3. Each tubular element I has a male end 2 and an opposite female end 3.
L'extrémité mâle 2 est pourvue de deux saillies la térales 4 décalées angulairement de 180 et situées à une distance 1 de l'extrémité libre. The male end 2 is provided with two protrusions the teral 4 angularly offset by 180 and located at a distance 1 from the free end.
Les saillies 4 sont constituées par des pièces découpées, mises en forme et soudées sur l'élément I. Chaque saillie 4 a une forme générale allongée rectangulaire dont un grand coté 5 constitue un bord de guidage tandis que l'autre grand côte presente une encoche 6 qui determine deux languettes 7 et 8, la languette 7 comportant des bords arrondis. The protrusions 4 are formed by cut pieces, shaped and welded on the element I. Each protrusion 4 has a generally elongated rectangular shape with a large side 5 constituting a guide edge while the other large rib has a notch 6 which determines two tongues 7 and 8, the tongue 7 having rounded edges.
L'extrémité femelle 3 comporte, soudé, un manchon IO dont le diamètre interne correspond au diametre externe de l'extrémité mâle 2. The female end 3 comprises, welded, a sleeve IO whose internal diameter corresponds to the external diameter of the male end 2.
Le manchon IO, sur son bord libre II, comporte une fente allongée I2 en forme de U renverse présentant deux bords longitudinaux I3 et I4, dans le bord I3 étant pratiquée une entaille transversale 15 dont la forme correspond à a forme de la languette 7, ladite entaille 15 se terminant par un redan 16 correspondant à l'encoche 6. The sleeve IO, on its free edge II, comprises an elongated slot I2 in the shape of a reverse U having two longitudinal edges I3 and I4, in the edge I3 being formed a transverse notch 15 whose shape corresponds to the shape of the tongue 7, said notch 15 ending in a step 16 corresponding to notch 6.
Le manchon IO comporte deux fentes I2 avec une entaille Jfjlecalées angulairement de 1800. The sleeve IO has two slots I2 with a Jfjl notched angularly 1800.
Sur le manchcn IO est montée coulissante une bague I8 qui comporte, décalés angulairement de 180 et soudés sur sa surface internedeux doigts 20, ceux-ci étant en partie en saillie par rapport à un bord 21 de ladite bague I8. Chaque doigt 20 est monté coulissant dans une fente I2 correspondante et la bague I8 estmaintenue par un anneau de butee 23 engagé sur le manchon IO et soudé le long du bord Il de celui-ci. On the sleeve IO is slidably mounted a ring I8 which comprises, angularly offset by 180 and welded on its inner surface two fingers 20, these being partly projecting relative to an edge 21 of said ring I8. Each finger 20 is slidably mounted in a corresponding slot I2 and the ring I8 is maintained by a stop ring 23 engaged on the sleeve IO and welded along the edge II thereof.
Le manchon IO est engagé sur l'élément tubulaire
I et soudé sur celui-ci de manière que la distance L comprise entre le bord de l'entaille 15 de l'extrémité correspondante dudit élément tubulaire I, soit légèrement supérieure à la distance 1.The IO sleeve is engaged on the tubular element
I and welded onto it so that the distance L between the edge of the notch 15 of the corresponding end of said tubular element I, is slightly greater than the distance 1.
Pour assembler deux éléments tubulaires I, on engage l'extrémité mâle 2 de l'un dans l'extrémité femelle 3 de l'autre de manière que les saillies 4 viennent se situer au droit des fentes I2. Lors de cette introduction, les saillies 4 repoussent les doigts 20 qui constituent des organes de verrouillage et la bague I8, puis on fait pivoter sur luimême l'un des éléments tubulaires I par rapport à l'autre, de manière que les languettes 7 s'engagent dans les entailles I5 et les redans I6 dans les encoches 6. Dans cette position les doigts 20 et la bague I8 peuvent revenir dans leur position initiale, la bague I8 butant contre l'anneau 23, tandis que les doigts 20 s'opposent au dégagement des languettes 7 des entailles 15. To assemble two tubular elements I, the male end 2 of one is engaged in the female end 3 of the other so that the projections 4 come to be located in line with the slots I2. During this introduction, the projections 4 repel the fingers 20 which constitute locking members and the ring I8, then one of the tubular elements I is pivoted on itself relative to the other, so that the tongues 7 s '' engage in the notches I5 and the notches I6 in the notches 6. In this position the fingers 20 and the ring I8 can return to their initial position, the ring I8 abutting against the ring 23, while the fingers 20 oppose when the tabs 7 are released from the notches 15.
On conçoit que l'invention offre une très grande sécurité et qu'une fois accouplés, les deux éléments I ne peuvent se détacher ltun de l'autre intempestivement. It is understood that the invention offers very high security and that once coupled, the two elements I cannot detach one from the other unexpectedly.
Un tel assemblage trouve une application particulièrement intéressante pour la réalisation de tours d'ét-aiement des tinées à supporter notamment des coffrages. Such an assembly finds a particularly advantageous application for the production of towers for supporting the structures, in particular for formwork.
Bien entendu, l'invention n'est pas limitée au mode de réalisation sui vient d'être décrit et qui a été représenté, on pourra y apporter de nombreuses modifications de détails sans sortir, pour cela, du cadre de l'invention. Of course, the invention is not limited to the embodiment which has just been described and which has been shown, many modifications of details can be made without departing from the scope of the invention.
