Poteau support pour une barrière de protection io Domaine technique de l'invention Support post for a protective barrier Technical field of the invention

L'invention est relative à un poteau support comprenant un fût allongé en bois, et des moyens d'ancrage dans le sol. Un tel poteau support peut être utilisé pour la fabrication d'une barrière de protection contre les risques 15 naturels, notamment les chutes de pierres, les avalanches, les coulées de boue ou de neige, etc... The invention relates to a support post comprising an elongated wooden shaft, and means for anchoring in the ground. Such a support post may be used for the manufacture of a barrier against natural hazards, in particular falling rocks, avalanches, mud or snowflows, etc.

État de la technique State of the art

20 Les poteaux en bois utilisés pour réaliser des supports de barrières de protection sont généralement constitués par des barreaux massifs de bois ancrés dans le sol par des étriers d'acier vissés à la base ou sur les flancs des barreaux par des moyens de fixation. Les étriers sont formés par des pièces découpées spécifiques tenant compte de la section de base des 25 barreaux de bois, et de la profondeur d'ancrage dans le béton ou dans le sol. Cette profondeur d'ancrage reste fixe pour chaque étrier, ce qui nécessite le stockage et la gestion d'une gamme d'étriers de différentes structures. La résistance mécanique d'un barreau de bois massif dépend de plus de la nature et de la section du bois utilisé. La mise en place de l'étrier d'ancrage 30 nécessite une emprise au sol plus ou moins importante en fonction de la nature du terrain. The wooden posts used to make protective barrier supports generally consist of solid wooden bars anchored in the ground by steel stirrups screwed to the base or on the sides of the bars by fastening means. The stirrups are formed by specific cut pieces taking into account the base section of the wooden bars, and the anchoring depth in the concrete or in the ground. This depth of anchoring remains fixed for each stirrup, which requires the storage and management of a range of stirrups of different structures. The strength of a solid wood bar depends more on the nature and the section of the wood used. The installation of the anchor 30 requires a greater or lesser footprint depending on the nature of the terrain.

Objet de l'invention Object of the invention

L'objet de l'invention consiste à réaliser un poteau en bois à tenue mécanique renforcé, et pouvant être installé rapidement indépendamment de la nature du terrain. The object of the invention is to provide a wooden post reinforced mechanical strength, and can be installed quickly regardless of the nature of the ground.

Le poteau support selon l'invention est caractérisé en ce que les moyens d'ancrage comportent une barre de renforcement métallique traversant coaxialement un alésage sur toute la longueur du fût, et un manchon de ~o retenue emmanché dans l'alésage à l'une des extrémités du fût pour coopérer à vissage avec la barre en assurant le réglage en longueur de la portion de barre saillante à sceller dans le sol, et du positionnement axial du fût le long de la barre scellée. The support post according to the invention is characterized in that the anchoring means comprise a metal reinforcing bar coaxially crossing a bore over the entire length of the barrel, and a sleeve of ~ o retained fitted into the bore to the one ends of the barrel to cooperate screwing with the bar ensuring the length adjustment of the protruding bar portion to be sealed in the ground, and the axial positioning of the barrel along the sealed bar.

15 Selon un mode de réalisation préférentiel, le manchon de retenue possède un filetage interne coopérant avec un filetage extérieur complémentaire s'étendant sur toute la longueur de la barre. Le manchon de retenue est métallique, et est totalement enfoncé dans l'alésage par l'extrémité inférieure du poteau. 20 Selon une caractéristique de l'invention, un capot de protection est avantageusement fixé sur la portion de barre dépassant l'extrémité supérieure du poteau. Ce capot peut être démontable ou verrouillable pour rendre le système inviolable. La hauteur du poteau peut varier par emboîtement vertical d'une pluralité d'éléments de poteaux sur la même barre de renforcement, ou sur deux éléments de barre alignés. 2 25 30 Description sommaire des dessins 3 According to a preferred embodiment, the retaining sleeve has an internal thread cooperating with a complementary external thread extending over the entire length of the bar. The retaining sleeve is metal, and is fully depressed into the bore by the lower end of the post. According to one characteristic of the invention, a protective cover is advantageously fixed on the portion of bar projecting beyond the upper end of the post. This cover can be removable or lockable to make the system tamper-proof. The height of the post may vary by vertically interlocking a plurality of post elements on the same reinforcing bar, or on two aligned bar elements. 2 25 30 Brief description of the drawings 3

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre de différents modes de réalisation de l'invention donnés à titre d'exemples non limitatifs et représentés aux dessins annexés, dans lesquels : la figure 1 est une vue en coupe axiale du poteau selon l'invention ; la figure 2 montre une coupe axiale d'un poteau dont la hauteur a été modifiée par emboîtement modulaire de deux éléments de poteaux illustrés à la figure 1. Other advantages and features will emerge more clearly from the following description of various embodiments of the invention given as non-limiting examples and shown in the accompanying drawings, in which: FIG. 1 is an axial sectional view post according to the invention; FIG. 2 shows an axial section of a column whose height has been modified by modular interlocking of two column elements illustrated in FIG.

Description détaillée de l'invention Detailed description of the invention

En référence à la figure 1, un poteau 10 support comprend un fût 18 allongé en bois, lequel est muni d'un alésage 11 axial débouchant des deux extrémités opposés 12, 13 du poteau. La section de l'alésage 11 est inférieure à celle du fût 18. La section du fût 18 peut être quelconque, notamment circulaire ou carrée. With reference to FIG. 1, a support post comprises an elongated wooden shaft 18, which is provided with an axial bore 11 opening out from the two opposite ends 12, 13 of the pole. The section of the bore 11 is smaller than that of the barrel 18. The section of the barrel 18 can be arbitrary, in particular circular or square.

Un manchon 14 de retenue tubulaire est emmanché axialement dans l'alésage 11 par l'extrémité inférieure 13 du poteau 10, et possède un filetage interne permettant de visser une barre 15 de renforcement métallique traversant l'alésage sur toute sa longueur. A tubular retaining sleeve 14 is axially engaged in the bore 11 by the lower end 13 of the post 10, and has an internal thread for screwing a metal reinforcing bar 15 through the bore along its entire length.

La barre 15 possède une longueur supérieure à celle du poteau 10, et est formée à titre d'exemple par une tige en acier ayant un filetage extérieur complémentaire au filetage interne du manchon 14 de retenue. Le filetage extérieur s'étend sur toute la longueur de la barre 15. The bar 15 has a length greater than that of the post 10, and is formed by way of example by a steel rod having an external thread complementary to the internal thread of the retaining sleeve 14. The external thread extends over the entire length of the bar 15.

La profondeur d'emmanchement du manchon 14 dans l'alésage 11 s'étend sur une fraction de la longueur axiale du poteau 10. Le manchon 14 est de préférence métallique, et est totalement enfoncé dans l'alésage 11. 4 The fitting depth of the sleeve 14 in the bore 11 extends over a fraction of the axial length of the post 10. The sleeve 14 is preferably metal, and is fully depressed in the bore 11. 4

La longueur de la portion de barre 15a faisant saillie de l'extrémité inférieure 13, est ajustable en vissant plus ou moins la barre 15 dans le manchon 14. Après réglage du dépassement, la portion de barre 15a est enfoncée et scellée dans le sol S. La présence du manchon 14 permet en plus d'assurer le positionnement axial du fût 18 en bois le long de la barre scellée. The length of the bar portion 15a protruding from the lower end 13 is adjustable by more or less screwing the bar 15 into the sleeve 14. After adjusting the overshoot, the bar portion 15a is depressed and sealed in the ground S The presence of the sleeve 14 also makes it possible to ensure the axial positioning of the wooden shaft 18 along the sealed bar.

Un capot 16 de protection est fixé sur la portion de barre 15b dépassant l'extrémité supérieure 12 du poteau 10. Le corps du capot 16 est tubulaire et présente un diamètre correspondant à celui du poteau 10 en bois. Il coiffe totalement l'extrémité supérieure 12 du poteau 10, et est équipé d'un embout 17 de fixation interne, lequel est fileté pour être vissé sur la portion de barre 15b. Le capot 16 est démontable par dévissage, ce qui permet de remplacer un poteau 10 endommagé tout en laissant la barre 15 de renforcement en place. A protective cover 16 is fixed on the bar portion 15b protruding from the upper end 12 of the post 10. The body of the cover 16 is tubular and has a diameter corresponding to that of the wooden post 10. It completely covers the upper end 12 of the post 10, and is equipped with an inner fixing end 17, which is threaded to be screwed onto the bar portion 15b. The cover 16 is dismountable by unscrewing, which makes it possible to replace a damaged post 10 while leaving the reinforcement bar 15 in place.

Selon une variante de réalisation, le capot 16 est verrouillé sur la portion de barre 15b par des moyens inviolables, ce qui empêche toute tentative de vandalisme. According to an alternative embodiment, the cover 16 is locked on the bar portion 15b by tamper-proof means, which prevents any attempt of vandalism.

Le montage à vis de la barre 15 en acier dans le manchon 14 de retenue, permet d'ajuster avec précision la longueur de la portion de barre 15a pour l'ancrage dans le sol. La barre 15 axiale renforce la résistance mécanique globale du poteau 10, lequel est vissé et immobilisé sur l'ancrage par l'intermédiaire du manchon 14. The screw mounting of the steel bar 15 in the retaining sleeve 14 makes it possible to precisely adjust the length of the bar portion 15a for anchoring in the ground. The axial bar strengthens the overall strength of the post 10, which is screwed and immobilized on the anchor via the sleeve 14.

Sur la figure 2, la hauteur totale du poteau 100 peut être augmentée rapidement en utilisant deux poteaux 100a, 100b élémentaires empilés l'un sur l'autre selon la direction verticale en étant emboîtés sur la même barre 15, dans ce cas plus longue que la barre de la figure 1. Chaque poteau 100a, 100b est équipé de son manchon 14 de retenue. Le poteau inférieur 100a est similaire à celui 10 de la figure 1, après avoir enlevé le capot 16 de protection, et la portion de barre 15a inférieure est scellée dans le sol. Le poteau supérieur 100b est identique à celui 10 de la figure 1. Le capot 16 de protection est fixé sur la portion de barre 15b supérieure du poteau 100b. In FIG. 2, the total height of the post 100 can be increased rapidly by using two elementary posts 100a, 100b stacked one on the other in the vertical direction while being nested on the same bar 15, in this case longer than the bar of Figure 1. Each post 100a, 100b is equipped with its retaining sleeve 14. The lower post 100a is similar to that of FIG. 1, after having removed the protective cover 16, and the lower bar portion 15a is sealed in the ground. The upper pole 100b is identical to that 10 of Figure 1. The cover 16 is fixed on the upper bar portion 15b of the pole 100b.

Selon une variante de la figure 2, au lieu d'utiliser la même barre 15 très 5 longue, il est possible de faire usage de deux barres 15 identiques à celles de la figure 1, lesquels sont vissées dans le manchon 14 correspondant de chaque poteau 100a, 100b. La portion de barre 15b supérieure qui fait saillie du poteau inférieur 100a est alors vissée dans le manchon 14 du poteau supérieur 100b. Il en résulte un alignement précis des deux barres 15 ~o consécutives grâce aux deux manchons 14 coaxiaux prévus à la base de chaque poteau 100a, 100b. According to a variant of Figure 2, instead of using the same bar 15 very long, it is possible to make use of two bars 15 identical to those of Figure 1, which are screwed into the sleeve 14 corresponding to each post 100a, 100b. The upper bar portion 15b projecting from the lower pole 100a is then screwed into the sleeve 14 of the upper pole 100b. This results in a precise alignment of the two bars 15 ~ o consecutive through the two coaxial sleeves 14 provided at the base of each pole 100a, 100b.
