Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne un poteau comportant un système anti-soulèvement. Un tel poteau est utilisé par exemple dans un bâtiment en construction pour protéger les personnels lorsque les garde-corps définitifs ne sont pas encore installés.The present invention relates to a post comprising an anti-uplift system. Such a post is used, for example, in a building under construction to protect personnel when the final guardrails have not yet been installed.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Dans un bâtiment en construction, il est connu d'utiliser des garde-corps temporaires qui sont implantés dans une dalle lorsque les garde-corps définitifs ne sont pas encore installés. Les garde-corps temporaires comportent des poteaux verticaux et des éléments horizontaux (lisses horizontales et plinthes ou panneaux grillagés, tubulaires ou en matière synthétique) qui sont fixés entre deux poteaux consécutifs.In a building under construction, it is known to use temporary guardrails which are installed in a slab when the final guardrails have not yet been installed. Temporary guardrails consist of vertical posts and horizontal elements (horizontal rails and plinths or mesh, tubular or synthetic material panels) which are fixed between two consecutive posts.

Chaque poteau est enfoncé dans une réservation réalisée dans la dalle ou dans un accessoire fixé sur la dalle.Each post is driven into a recess made in the slab or in an accessory fixed to the slab.

Pour éviter que les poteaux se soulèvent non intentionnellement, il est prévu à chaque poteau un système anti-soulèvement. Un tel système anti-soulèvement prend par exemple la forme d'une tige métallique montée articulée sur le poteau et qui s'arcboute et bloque le soulèvement du poteau lorsque ce soulèvement n'est pas intentionnel.To prevent the posts from lifting unintentionally, each post is equipped with an anti-lifting system. Such an anti-lifting system takes for example the form of a metal rod mounted articulated on the post and which braces and blocks the lifting of the post when this lifting is not intentional.

Bien qu'un tel système donne entière satisfaction, il est souhaitable de trouver un système de soulèvement plus simple à mettre en oeuvre. US4752060 A divulgue un poteau avec un système anti-soulèvement.Although such a system gives complete satisfaction, it is desirable to find a lifting system that is simpler to implement. US4752060A discloses a pole with an anti-uplift system.

EXPOSE DE L'INVENTIONDISCLOSURE OF THE INVENTION

Un objet de la présente invention est de proposer un poteau comportant un système anti-soulèvement qui soit facile à mettre en oeuvre. Cet objectif et d'autres sont réalisés par un poteau selon la revendication 1.An object of the present invention is to provide a post comprising an anti-lifting system which is easy to implement. This and other objectives are achieved by a post according to claim 1.

A cet effet, est proposé un poteau comportant :

  • un montant présentant une partie basse,
  • un premier cylindre présentant un premier axe de révolution, une partie basse et une partie haute solidaire de la partie basse du montant,
  • un deuxième cylindre présentant un deuxième axe de révolution désaxé par rapport au premier axe de révolution, et une partie haute solidaire de la partie basse du premier cylindre, où le diamètre du deuxième cylindre est inférieur au diamètre du premier cylindre de manière à former entre eux un épaulement,
  • un élément tubulaire percé d'un alésage coaxial avec le deuxième axe de révolution et qui s'emmanche sur le deuxième cylindre pour venir en appui contre l'épaulement, où l'élément tubulaire présente une surface extérieure cylindrique dont l'axe de révolution est désaxé par rapport au deuxième axe de révolution, et
  • un moyen d'arrêt qui bloque la translation de l'élément tubulaire le long du deuxième cylindre.
For this purpose, a post is proposed comprising:
  • an upright having a lower part,
  • a first cylinder having a first axis of revolution, a lower part and an upper part integral with the lower part of the upright,
  • a second cylinder having a second axis of revolution offset with respect to the first axis of revolution, and an upper part integral with the lower part of the first cylinder, where the diameter of the second cylinder is smaller than the diameter of the first cylinder so as to form a shoulder between them,
  • a tubular element pierced with a bore coaxial with the second axis of revolution and which fits onto the second cylinder to bear against the shoulder, where the tubular element has a cylindrical outer surface whose axis of revolution is offset with respect to the second axis of revolution, and
  • a stop means which blocks the translation of the tubular element along the second cylinder.

Grâce à ce système, le poteau se verrouille simplement par rotation lorsqu'il est dans une réservation prévue à cet effet.Thanks to this system, the post simply locks by rotation when it is in a space provided for this purpose.

Avantageusement, le désaxage entre l'axe de révolution de la surface extérieure cylindrique et le deuxième axe de révolution est tel qu'il existe une position angulaire de l'élément tubulaire pour laquelle l'axe de révolution de la surface extérieure cylindrique et le premier axe de révolution sont coaxiaux.Advantageously, the offset between the axis of revolution of the cylindrical outer surface and the second axis of revolution is such that there is an angular position of the tubular element for which the axis of revolution of the cylindrical outer surface and the first axis of revolution are coaxial.

Avantageusement, le diamètre de la surface extérieure cylindrique de l'élément tubulaire est supérieur au diamètre du premier cylindre.Advantageously, the diameter of the cylindrical outer surface of the tubular element is greater than the diameter of the first cylinder.

Avantageusement, la différence entre le diamètre de la surface extérieure cylindrique de l'élément tubulaire et le diamètre du premier cylindre est de l'ordre de 0,5 mm.Advantageously, the difference between the diameter of the cylindrical outer surface of the tubular element and the diameter of the first cylinder is of the order of 0.5 mm.

Avantageusement, le moyen d'arrêt comporte un élément tubulaire complémentaire fixé au deuxième cylindre, où l'élément tubulaire complémentaire est percé d'un alésage complémentaire coaxial avec le deuxième axe de révolution et qui s'emmanche sur le deuxième cylindre pour venir en appui contre l'élément tubulaire, où l'élément tubulaire complémentaire comporte une surface externe cylindrique dont l'axe de révolution est désaxé par rapport au deuxième axe de révolution, où l'axe de révolution de la surface externe cylindrique est coaxial avec le premier axe de révolution.Advantageously, the stopper means comprises a complementary tubular element fixed to the second cylinder, where the complementary tubular element is pierced with a complementary bore coaxial with the second axis of revolution and which fits onto the second cylinder to come to rest against the tubular element, where the complementary tubular element comprises a cylindrical external surface whose axis of revolution is offset with respect to the second axis of revolution, where the axis of revolution of the cylindrical external surface is coaxial with the first axis of revolution.

Avantageusement, le diamètre de la surface externe cylindrique est égal au diamètre du premier cylindre.Advantageously, the diameter of the cylindrical outer surface is equal to the diameter of the first cylinder.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec le dessin joint, où
[Fig. 1] est une vue éclatée et en perspective d'un poteau selon l'invention.The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the attached drawing, where
[ Fig. 1 ] is an exploded perspective view of a post according to the invention.

EXPOSE DETAILLE DE MODES DE REALISATIONDETAILED DESCRIPTION OF EMBODIMENTS

La Fig. 1 montre un poteau 100 selon l'invention. Dans la description qui suit, les termes relatifs à une position sont pris en référence à un poteau 100 disposé verticalement, c'est-à-dire comme il est représenté sur la Fig. 1.There Fig. 1 shows a post 100 according to the invention. In the following description, the terms relating to a position are taken in reference to a post 100 arranged vertically, that is to say as it is represented on the Fig. 1 .

Le poteau 100 comporte un montant 102 qui est ici cylindrique mais pourrait prendre une autre forme. Le poteau 100 est destiné à être inséré dans une réservation 50 cylindrique réalisée dans une dalle 10, en particulier dans une dalle en béton. Chaque poteau 100 est disposé près d'un autre poteau 100 identique, pour permettre de fixer entre eux, une lisse afin que les poteaux 100 et la lisse constituent un garde-corps.The post 100 includes an upright 102 which is cylindrical here but could take another shape. The post 100 is intended to be inserted into a cylindrical reservation 50 made in a slab 10, in particular in a concrete slab. Each post 100 is arranged close to another identical post 100, to allow fixing between them, a smooth so that the posts 100 and the smooth constitute a guardrail.

Le poteau 100 comporte en partie basse un premier cylindre 104 qui s'étend verticalement et qui comporte un premier axe de révolution 52. Le premier cylindre 104 s'étend sous le montant 102, c'est-à-dire que la partie haute du premier cylindre 104 est solidaire de la partie basse du montant 102. Dans le mode de réalisation de l'invention présenté ici, le premier cylindre 104 et le montant 102 sont coaxiaux mais ils pourraient être désaxés l'un par rapport à l'autre.The post 100 comprises in the lower part a first cylinder 104 which extends vertically and which comprises a first axis of revolution 52. The first cylinder 104 extends under the upright 102, that is to say that the upper part of the first cylinder 104 is integral with the lower part of upright 102. In the embodiment of the invention presented here, first cylinder 104 and upright 102 are coaxial but they could be offset with respect to each other.

Le poteau 100 comporte également un deuxième cylindre 106 qui s'étend verticalement et qui comporte un deuxième axe de révolution 54 parallèle au premier axe de révolution 52 mais différent, c'est-à-dire à distance, dudit premier axe de révolution 52, c'est-à-dire que le deuxième cylindre 106 et le premier cylindre 104 sont désaxés l'un par rapport à l'autre. Le deuxième cylindre 106 s'étend sous le premier cylindre 104, c'est-à-dire que la partie haute du deuxième cylindre 106 est solidaire de la partie basse du premier cylindre 104. Le diamètre du deuxième cylindre 106 est inférieur au diamètre du premier cylindre 104 de manière à former entre eux un épaulement 112.The post 100 also comprises a second cylinder 106 which extends vertically and which comprises a second axis of revolution 54 parallel to the first axis of revolution 52 but different, that is to say at a distance, from said first axis of revolution 52, that is to say that the second cylinder 106 and the first cylinder 104 are offset with respect to each other. The second cylinder 106 extends under the first cylinder 104, that is to say that the upper part of the second cylinder 106 is integral with the lower part of the first cylinder 104. The diameter of the second cylinder 106 is smaller than the diameter of the first cylinder 104 so as to form between them a shoulder 112.

Le diamètre du premier cylindre 104 est inférieur au diamètre de la réservation 50 pour assurer l'introduction dudit premier cylindre 104 dans ladite réservation 50. La profondeur de la réservation 50 est telle que le deuxième cylindre 106 et la majeure partie du premier cylindre 104 et préférentiellement la totalité dudit premier cylindre 104 s'insère dans la réservation 50 et que le montant 102 vient en appui sur la dalle 10 hors de la réservation 50. La différence entre le diamètre de la réservation 50 et le diamètre du premier cylindre 104 ne doit pas être trop importante pour éviter les risques de mouvements de fortes amplitudes du premier cylindre 104 dans la réservation 50. Préférentiellement la différence de diamètre est de l'ordre de 1 à 3 mm et plus préférentiellement de 2 mm, pour un diamètre du premier cylindre 104 généralement compris entre 25 mm et 40 mm.The diameter of the first cylinder 104 is smaller than the diameter of the reservation 50 to ensure the introduction of said first cylinder 104 into said reservation 50. The depth of the reservation 50 is such that the second cylinder 106 and the major part of the first cylinder 104 and preferably all of said first cylinder 104 is inserted into the reservation 50 and that the amount 102 bears against the slab 10 outside the reservation 50. The difference between the diameter of the reservation 50 and the diameter of the first cylinder 104 should not not be too large to avoid the risk of high amplitude movements of the first cylinder 104 in the reservation 50. Preferably the difference in diameter is of the order of 1 to 3 mm and more preferably 2 mm, for a diameter of the first cylinder 104 generally between 25 mm and 40 mm.

Le poteau 100 comporte un élément tubulaire 108 qui est percé d'un alésage 110 coaxial avec le deuxième axe de révolution 54 et qui s'emmanche sur le deuxième cylindre 106 pour venir en appui contre l'épaulement 112 en restant libre en rotation autour du deuxième cylindre 106.The post 100 comprises a tubular element 108 which is pierced with a bore 110 coaxial with the second axis of revolution 54 and which is fitted onto the second cylinder 106 to bear against the shoulder 112 while remaining free in rotation around the second cylinder 106.

Le diamètre de l'alésage 110 est légèrement supérieur au diamètre du deuxième cylindre 106. L'ajustement entre l'alésage 110 et le deuxième cylindre 106 est préférentiellement glissant pour permettre le glissement de l'élément tubulaire 108 le long du deuxième cylindre 106 parallèlement aux axes de révolution 52 et 54 et la rotation de l'élément tubulaire 108 autour du deuxième cylindre 106.The diameter of the bore 110 is slightly greater than the diameter of the second cylinder 106. The fit between the bore 110 and the second cylinder 106 is preferentially sliding to allow sliding of the tubular element 108 along the second cylinder 106 parallel to the axes of revolution 52 and 54 and the rotation of the tubular element 108 around the second cylinder 106.

L'axe de révolution de la surface extérieure cylindrique de l'élément tubulaire 108 est désaxé par rapport à l'axe de révolution de l'alésage 110, c'est-à-dire du deuxième axe de révolution 54, c'est-à-dire que l'axe de révolution de la surface extérieure cylindrique et le deuxième axe de révolution 54 sont parallèles mais différents.The axis of revolution of the cylindrical outer surface of the tubular element 108 is offset with respect to the axis of revolution of the bore 110, that is to say of the second axis of revolution 54, i.e. that is, the axis of revolution of the cylindrical outer surface and the second axis of revolution 54 are parallel but different.

Le diamètre de la surface extérieure cylindrique de l'élément tubulaire 108 est inférieur au diamètre de la réservation 50 pour assurer l'introduction dudit élément tubulaire 108 dans ladite réservation 50. La différence entre le diamètre de la réservation 50 et le diamètre de la surface extérieure cylindrique de l'élément tubulaire 108 doit être relativement réduite pour assurer le frottement de ladite surface extérieure cylindrique contre la paroi de la réservation 50. Préférentiellement la différence de diamètre est de l'ordre de 0,5 mm à 2,5 mm et plus préférentiellement de l'ordre de 1,5 mm pour un diamètre de la surface extérieure cylindrique de l'élément tubulaire 108 compris généralement entre 25 mm et 40 mm.The diameter of the cylindrical outer surface of the tubular element 108 is smaller than the diameter of the reservation 50 to ensure the introduction of said tubular element 108 into said reservation 50. The difference between the diameter of the reservation 50 and the diameter of the surface cylindrical outer surface of the tubular element 108 must be relatively small to ensure the friction of said cylindrical outer surface against the wall of the reservation 50. Preferably the difference in diameter is of the order of 0.5 mm to 2.5 mm and more preferably of the order of 1.5 mm for a diameter of the cylindrical outer surface of the tubular element 108 generally comprised between 25 mm and 40 mm.

D'une manière préférentielle, pour assurer le frottement de la surface extérieure cylindrique de l'élément tubulaire 108 contre la paroi de la réservation 50, tout en laissant libre l'introduction du poteau dans la réservation 50, le diamètre de la surface extérieure cylindrique de l'élément tubulaire 108 est supérieur au diamètre du premier cylindre 104, et, préférentiellement, la différence de diamètre est de l'ordre de 0,5 mm pour un diamètre de la surface extérieure cylindrique de l'élément tubulaire 108 compris généralement entre 25 mm et 40 mm.Preferably, to ensure the friction of the cylindrical outer surface of the tubular element 108 against the wall of the reservation 50, while leaving free the introduction of the post into the reservation 50, the diameter of the cylindrical outer surface of the tubular element 108 is greater than the diameter of the first cylinder 104, and, preferably, the difference in diameter is of the order of 0.5 mm for a diameter of the cylindrical outer surface of the tubular element 108 generally comprised between 25mm and 40mm.

Le poteau 100 comporte également un moyen d'arrêt 120 qui bloque la translation de l'élément tubulaire 108 le long du deuxième cylindre 106 et le maintien en appui contre l'épaulement 112 tout en laissant l'élément tubulaire 108 libre de tourner autour du deuxième cylindre 106.The post 100 also comprises a stop means 120 which blocks the translation of the tubular element 108 along the second cylinder 106 and keeping it bearing against the shoulder 112 while leaving the tubular element 108 free to rotate around the second cylinder 106.

Ainsi, lorsque l'élément tubulaire 108 libre en rotation, le premier cylindre 104 et le deuxième cylindre 106 sont introduits dans la réservation 50, le montant 102 et donc le premier cylindre 104 et le deuxième cylindre 106 sont ensuite déplacés en rotation dans un premier sens autour du premier axe de révolution 52 ce qui tend à générer un effort de pincement lorsque l'élément tubulaire 108 se décale par rapport au premier axe de révolution 52 en frottant sa surface extérieure cylindrique contre la paroi de la réservation 50.Thus, when the tubular element 108 rotates freely, the first cylinder 104 and the second cylinder 106 are introduced into the reservation 50, the upright 102 and therefore the first cylinder 104 and the second cylinder 106 are then moved in rotation in a first direction around the first axis of revolution 52 which tends to generate a pinching force when the tubular element 108 shifts relative to the first axis of revolution 52 by rubbing its cylindrical outer surface against the wall of the reservation 50.

Une rotation dans le sens inverse permet de libérer l'élément tubulaire 108 et de retirer le poteau 100 de la réservation 50.A rotation in the opposite direction makes it possible to release the tubular element 108 and to remove the post 100 from the reservation 50.

Ainsi le poteau 100 a une constitution simple et sa mise en oeuvre est rapide et aisée.Thus the post 100 has a simple construction and its implementation is quick and easy.

Pour faciliter l'introduction du poteau 100 dans la réservation 50, le désaxage entre l'axe de révolution de la surface extérieure cylindrique et le deuxième axe de révolution 54 est tel qu'il existe une position angulaire de l'élément tubulaire 108 autour du deuxième axe de révolution 54 pour laquelle l'axe de révolution de la surface extérieure cylindrique et le premier axe de révolution 52 sont coaxiaux. Ainsi, l'encombrement du poteau 100 est minimal autour du premier axe de révolution 52, ce qui facilite l'introduction du poteau 100 dans la réservation 50.To facilitate the introduction of the post 100 into the reservation 50, the offset between the axis of revolution of the cylindrical outer surface and the second axis of revolution 54 is such that there is an angular position of the tubular element 108 around the second axis of revolution 54 for which the axis of revolution of the cylindrical outer surface and the first axis of revolution 52 are coaxial. Thus, the size of the post 100 is minimal around the first axis of revolution 52, which facilitates the introduction of the post 100 into the reservation 50.

Le moyen d'arrêt 120 peut prendre différentes formes. Par exemple, il peut s'agir d'une rondelle soudée au voisinage de la partie basse du deuxième cylindre 106.The stop means 120 can take different forms. For example, it may be a washer welded near the lower part of the second cylinder 106.

Dans le mode de réalisation de l'invention présenté à la Fig. 1, le moyen d'arrêt 120 comporte un élément tubulaire complémentaire 122 fixé au deuxième cylindre 106.In the embodiment of the invention presented in Fig. 1 , the stop means 120 comprises a complementary tubular element 122 fixed to the second cylinder 106.

L'élément tubulaire complémentaire 122 est percé d'un alésage complémentaire 124 coaxial avec le deuxième axe de révolution 54 et qui s'emmanche sur le deuxième cylindre 106 pour venir en appui contre l'élément tubulaire 108.The complementary tubular element 122 is pierced with a complementary bore 124 coaxial with the second axis of revolution 54 and which fits onto the second cylinder 106 to bear against the tubular element 108.

L'élément tubulaire complémentaire 122 comporte une surface externe cylindrique dont l'axe de révolution est désaxé par rapport à l'axe de révolution de l'alésage complémentaire 124, c'est-à-dire du deuxième axe de révolution 54, c'est-à-dire que l'axe de révolution de la surface externe cylindrique et le deuxième axe de révolution 54 sont parallèles mais différents.The complementary tubular element 122 comprises a cylindrical outer surface whose axis of revolution is offset with respect to the axis of revolution of the complementary bore 124, that is to say of the second axis of revolution 54, it that is, the axis of revolution of the cylindrical outer surface and the second axis of revolution 54 are parallel but different.

L'axe de révolution de la surface externe cylindrique est coaxial avec le premier axe de révolution 52 et, préférentiellement, son diamètre est égal au diamètre du premier cylindre 104.The axis of revolution of the cylindrical outer surface is coaxial with the first axis of revolution 52 and, preferably, its diameter is equal to the diameter of the first cylinder 104.

Dans le mode de réalisation de l'invention présenté sur la Fig. 1, la fixation de l'élément tubulaire complémentaire 122 est assurée par une goupille 123, ici une goupille fendue.In the embodiment of the invention shown in Fig. 1 , the fixing of the complementary tubular element 122 is ensured by a pin 123, here a cotter pin.

L'élément tubulaire complémentaire 122 présente un perçage 126 qui le traverse perpendiculairement au deuxième axe de révolution 54 et le deuxième cylindre 106 présente également un perçage 128 qui le traverse perpendiculairement au deuxième axe de révolution 54 et qui est prévu pour s'aligner avec le perçage 126 de l'élément tubulaire complémentaire 122 pour permettre la mise en place de la goupille 123 qui traverse alors le perçage 126, l'élément tubulaire complémentaire 122 et le perçage 128 du deuxième cylindre 106.The complementary tubular element 122 has a bore 126 which passes through it perpendicular to the second axis of revolution 54 and the second cylinder 106 also has a bore 128 which passes through it perpendicular to the second axis of revolution 54 and which is designed to align with the drilling 126 of the complementary tubular element 122 to allow the positioning of the pin 123 which then passes through the bore 126, the complementary tubular element 122 and the bore 128 of the second cylinder 106.

Bien sûr, la fixation de l'élément tubulaire complémentaire 122 peut être assurée par tous autres moyens comme par exemple un point de soudure.Of course, the fixing of the complementary tubular element 122 can be ensured by any other means such as for example a spot weld.
