Abstract

The mast (1) has a fixing plate at a base for being anchored on a concrete block at top. The top of the mast has a traffic sign attached on an attachment zone. A bottom part (1A) is surmounted on a top part (1B). The bottom part is constituted by a post with polygonal section. The post has faces structured to being deformed so as to be detached from the fixing plate. The top part is constituted by a tube with overall circular section offering a large number of orientations of the traffic sign than that of the bottom part. The bottom part has length in order of 1.5 to 2.5 meters.

Description

L'invention se rapporte à un dispositif de signalisation routière.The invention relates to a road signaling device.

Pour la signalisation routière, on utilise des panneaux portés par un mât fixé au sol à proximité des voies de circulations. Le panneau doit être positionné à une hauteur suffisante pour être visible de loin et donc généralement au dessus de 2 mètres.Road signage uses panels carried by a mast attached to the ground near the traffic lanes. The panel must be positioned at a height sufficient to be visible from a distance and therefore generally above 2 meters.

Les mâts des panneaux de circulation situés le long des routes doivent en cas de choc se déformer afin d'absorber une partie de l'énergie cinétique ou bien se détache. Les critères de performance de ces poteaux sont définis par des normes. Les normes sont de plus en plus contraignantes et il faut faire évoluer les moyens tant pour les nouveaux panneaux que pour les anciens.The masts of the traffic signs located along the roads must in case of shock deform to absorb some of the kinetic energy or detach. The performance criteria of these poles are defined by standards. Standards are becoming more stringent and the means must be changed for both new panels and old ones.

La majorité des poteaux sont à section sensiblement circulaire car plus simple à produire et permettant d'orienter facilement le panneau grâce à des fixations par bride collier. Ce type de fixation est très largement usité.The majority of poles are substantially circular section because easier to produce and for easy orientation of the panel with fasteners clamp collar. This type of fixation is very widely used.

Il y a donc les poteaux, généralement globalement cylindriques de révolution dont la variable de contrôle de la résistance est l'épaisseur. Ce sont des poteaux en acier ou en aluminium filé. En agissant sur l'épaisseur et le diamètre, on obtient certaines performances. Mais d'autres types de poteaux sont meilleurs.There are therefore poles, generally globally cylindrical of revolution whose resistance control variable is the thickness. These are poles made of steel or spun aluminum. By acting on the thickness and the diameter, certain performances are obtained. But other types of poles are better.

Ainsi, pour d'autres poteaux réalisés en matériau composite, la variable d'ajustement de résistance est la nature du matériau ainsi que la construction du poteau qui utilise, par exemple, des fibres longues enroulées sur un mandrin. La manière d'enrouler et l'épaisseur sont des paramètres d'ajustement.Thus, for other posts made of composite material, the resistance adjustment variable is the nature of the material and the construction of the pole which uses, for example, long fibers wound on a mandrel. The winding way and the thickness are adjustment parameters.

Il existe également, les poteaux à section polygonale, et c'est la structure géométrique de chaque face du poteau qui permet de contrôler la déformation. Ce sont des faces non pleines ( par exemple, la paroi comporte des lumières ou forme un treillis déformable).Ces poteaux offrent des capacités de déformation très bonnes mais ils sont couteux.There are also poles polygonal section, and it is the geometric structure of each face of the post that can control the deformation. These are non-solid faces (for example, the wall has lights or forms a deformable lattice). These poles offer very good deformation capabilities but they are expensive.

Ces poteaux doivent être fixés au sol.These posts must be fixed to the ground.

Pour les poteaux du premier type en métal à section circulaire, la base de ces poteaux est fixée soit sur une platine métallique qui est alors fixée classiquement sur un massif béton d'ancrage soit par un système existant de sabots.For poles of the first type metal circular section, the base of these posts is fixed either on a metal plate which is then conventionally fixed on a solid concrete anchor or by an existing system of hooves.

Pour les seconds types de poteaux, ledit poteau doit être noyé dans un lit de béton profond d'environ 1 mètre ou plus. L'infrastructure est couteuse. Lorsqu'il est abimé lors d'un choc, les travaux nécessitent de remplacer le lit de béton. Il ne peut donc s'adapter sur les massifs en béton existantsFor the second types of posts, said post must be embedded in a deep concrete bed about 1 meter or more. The infrastructure is expensive. When damaged during a shock, the work requires replacing the concrete bed. It can not adapt to the existing concrete massifs

Pour les troisièmes poteaux, la base du polygone est fixée sur une platine qui vient prendre appui sur un massif en béton. Ils sont compatibles avec les massifs existants.For the third poles, the base of the polygon is fixed on a plate which comes to rest on a concrete mass. They are compatible with existing massifs.

Ces poteaux reçoivent en leur extrémité haute au moins un panneau de signalisation.These poles receive at their high end at least one sign.

Ce panneau de signalisation doit être orienté d'une certaine manière par rapport aux directions des voies de circulation.This sign must be oriented in a certain way with respect to the directions of the taxiways.

Cette orientation ne pose pas de problème pour les panneaux des premiers et deuxièmes types de poteaux car ils ont globalement une section circulaire et toutes les orientations sont possibles.This orientation does not pose a problem for the panels of the first and second types of posts because they have a circular section overall and all orientations are possible.

Pour le poteau du troisième type, les systèmes connus viennent appliquer le panneau parallèlement à une des faces du poteau. Par conséquent, les orientations sont réduites au nombre de faces du poteau généralement à quatre faces ce qui est restreint. Compte tenu que l'ancrage au sol se fait en boulonnant les quatre coins du mât au moyen de quatre vis dont les têtes sont noyées dans le béton, l'orientation du massif doit être déterminée au préalable.For the post of the third type, known systems apply the panel parallel to one of the faces of the pole. Therefore, the orientations are reduced to the number of faces of the generally four-sided pole which is restricted. Given that the anchoring to the ground is done by bolting the four corners of the mast by means of four screws whose heads are embedded in the concrete, the orientation of the massif must be determined beforehand.

Lors de l'installation du poteau, il faut alors définir l'orientation du massif en béton pour orienter correctement le poteau et son panneau de signalisation.When installing the post, it is necessary to define the orientation of the concrete block to correctly orient the post and its sign.

Cette solution contraignante ne fonctionne pas pour le remplacement des poteaux existants pour lesquels le massif en béton a été coulé sans orientation particulière. Il faut alors couler un nouveau massif.This restrictive solution does not work for the replacement of existing columns for which the concrete block was poured without any particular orientation. It must then sink a new massif.

Les collectivités locales souhaitent équiper leurs villes de ces poteaux spéciaux mais elles souhaiteraient le faire à moindre frais.Local authorities want to equip their cities with these special poles, but they would like to do so at lower cost.

L'invention vise à apporter un remède à ces problèmes de substitution de poteaux.The aim of the invention is to provide a remedy for these post substitution problems.

Il est connu FR 2183894 , un mât d'éclairage courbé en sa partie supérieure pour positionner la lampe au dessus de la route. Ce mât présente un pied modifié pour le rendre plus élastique lors d'un choc. Pour cela le mât qui est formé à partir d'un tube est coupé selon 4 génératrices pour former quatre jambes qui s'écartent vers le bas. Ces jambes peuvent être rapportées par soudures. Du fait de leur écartement progressif et du poids du lampadaire, il faut éventuellement reliée par un treillis d'entretoises ces jambes pour augmenter la résistance au flambage ( résistance à la charge verticale). Dans ce document il n'est pas mentionné de problème d'orientation d'un panneau sur le haut du lampadaire.He is known FR 2183894 , a lighting mast bent at the top to position the lamp above the road. This mast has a modified foot to make it more elastic during a shock. For this, the mast that is formed from a tube is cut along 4 generators to form four legs that move downwards. These legs can be reported by welding. Because of their gradual spacing and the weight of the lamp, it is eventually necessary to connect by a grid of spacers these legs to increase the resistance to buckling (resistance to vertical load). In this document there is no mention of a problem of orientation of a panel on the top of the lamppost.

A cet effet, l'invention se rapporte à dispositif de signalisation routière comprenant au moins un panneau de signalisation fixé au sommet d'un mât de signalisation tubulaire droit à déformation contrôlée comprenant à la base une platine de fixation destinée à être ancrée sur un massif en béton ce mât de signalisation étant caractérisé en ce que le mât se compose de deux parties dites basse et haute assemblées au moyen d'une pièce dite de séparation, la dite partie basse étant celle ayant les capacités de déformation exigée et se présentant comme un poteau à section constante polygonale dont les faces sont structurées pour se déformer , la dite partie basse étant reliée à la platine par des moyens de liaison à rupture contrôlée et la dite partie haute étant constituée par au moins un tube à section globalement circulaire présentant une surface cylindrique de rotation pour l'appui d'une bride de fixation du panneau permettant de l'orienter selon un azimut pris entre 0 et 360° offrant ainsi un plus grand nombre d'orientations possible du panneau de signalisation que celles offertes par la partie basse.For this purpose, the invention relates to a road signaling device comprising at least one sign posted at the top of a straight tubular signaling mast with controlled deformation comprising at the base a mounting plate intended to be anchored on a solid mass. in concrete this signaling mast being characterized in that the mast consists of two parts said low and high assembled by means of a so-called part separation, the said part low being the one having the required deformation capabilities and presenting as a post with a polygonal constant section whose faces are structured to deform, said lower part being connected to the plate by connecting means to controlled rupture and said upper part being constituted by at least one generally circular section tube having a cylindrical surface of rotation for the support of a fastening flange of the panel making it possible to orient it along an azimuth taken between 0 and 360 ° thus offering a greater number of possible orientations of the sign that those offered by the lower part.

L'invention sera bien comprise à l'aide de la description ci après faite à titre d'exemple non limitatif en regard du dessin qui représente :

  • FIG 1 : Mât de sécurité actuel
  • FIG 2 :Panneau monté sur mâts selon l'invention
  • FIG 3 Mât selon l'invention
  • FIG 4 :Mât percuté
The invention will be better understood from the following description given by way of non-limiting example with reference to the drawing which represents:
  • FIG 1 : Current security mast
  • FIG 2 : Panel mounted on poles according to the invention
  • FIG 3 Mast according to the invention
  • FIG 4 : Rammed mast

En se reportant au dessin, on voit un mât 1 de signalisation de sécurité présentant en son sommet un panneau 2 de signalisation qui s'accroche sur une zone 3 dite d'accrochage.Referring to the drawing, we see a mast 1 security signaling having at its top a sign 2 which clings to a zone 3 said hooking.

Ce mât de signalisation est fixé au sol, par exemple, au moyen d'une platine 4 et de boulons ancrés dans un massif 5 en béton.This signal mast is fixed to the ground, for example, by means of a plate 4 and bolts anchored in a solid 5 concrete.

Ce mât tubulaire est conçu pour une déformation contrôlée respectant une norme. Il est droit.This tubular mast is designed for controlled deformation respecting a standard. He is right.

En figure 1 on a représenté un mât de sécurité respectant la norme Européenne EN 12767. Le panneau est accroché en haut et peut prendre quatre orientations qui sont imposées par les quatre faces du mât. Il s'agit d'un exemple de mât mais d'autres mâts se présentant différemment sont dans le commerce.In figure 1 a safety pole has been shown which complies with the European standard EN 12767. The panel is hung at the top and can take four orientations which are imposed by the four sides of the mast. This is an example of a mast but other masts appearing differently are commercially available.

Avantageusement, le mât 1 se compose de deux parties 1A, 1B, une partie basse 1A surmontée d'une partie haute la dite partie basse étant constituée par un poteau à section polygonale dont les faces sont structurées pour se déformer selon un schéma programmé et se détacher d'une platine 4 et la dite partie haute étant constituée par au moins un tube à section globalement circulaire offrant un plus grand nombre d'orientations du panneau de signalisation que celles offertes par la partie basse.Advantageously, the mast 1 is composed of two parts 1A, 1B, a lower part 1A surmounted by an upper part, said lower part being constituted by a post with a polygonal section whose faces are structured to deform according to a programmed pattern and detaching a plate 4 and said upper portion being constituted by at least one generally circular section tube providing a greater number of orientations of the sign that those offered by the lower part.

Ainsi les deux parties dites basse et haute sont assemblées au moyen d'une pièce dite de séparation, la dite partie basse étant celle ayant les capacités de déformation exigée et se présentant comme un poteau à section constante polygonale dont les faces sont structurées pour se déformer , la dite partie basse étant reliée à la platine par des moyens de liaison à rupture contrôlée et la dite partie haute étant constituée par au moins un tube à section globalement circulaire présentant une surface cylindrique de rotation pour l'appui d'une bride de fixation du panneau permettant de l'orienter selon un azimut pris entre 0 et 360° offrant ainsi un plus grand nombre d'orientations possible du panneau de signalisation que celles offertes par la partie basse.Thus the two so-called low and high parts are assembled by means of a so-called separation part, the said lower part being the one having the required deformation capacities and presenting itself as a post with a polygonal constant section whose faces are structured to deform said lower part being connected to the plate by means of controlled-breaking connection means and said upper part being constituted by at least one generally circular section tube having a cylindrical surface of rotation for the support of a fastening flange the panel to orient it according to an azimuth taken between 0 and 360 ° thus providing a greater number of possible orientations of the sign that those offered by the lower part.

La deuxième partie du mât est un tube du type utilisé sur les poteaux de signalisation de l'art antérieur que l'on souhaite remplacer. La surface d'accrochage est soit une surface cylindrique de révolution à rayon constant soit une surface cylindrique à multi-facettes ( rayon non constant).The second part of the mast is a tube of the type used on the signaling posts of the prior art that it is desired to replace. The attachment surface is either a cylindrical surface of revolution with a constant radius or a cylindrical surface with multi-facets (non-constant radius).

Ainsi, en construisant un mât avec des composants différents, on apporte, grâce à la base spécifique, une sécurité lors d'un accident et une solution à l'orientation des panneaux de signalisation qui permet notamment de réutiliser des éléments de l'ancien dispositif de signalisation.Thus, by constructing a mast with different components, it is possible, thanks to the specific base, to provide safety during an accident and a solution to the orientation of the traffic signs, which makes it possible in particular to reuse elements of the old device. signaling.

Pour les poteaux à section polygonale, les orientations possible et simple sont limités au nombre de face du poteau (quatre ou six faces alors que pour un poteau à section circulaire, le nombre de position est infini.For poles with polygonal cross section, the possible and simple orientations are limited to the number of face of the column (four or six faces whereas for a column with circular section, the number of positions is infinite.

On limite le coût car la longueur utilisée du poteau à section polygonale et à déformation spécifique répondant a la norme Européenne EN 12767 est réduite significativement.The cost is limited because the length used of the post with polygonal section and specific deformation meeting the European standard EN 12767 is reduced significantly.

La longueur sera d'au moins 1 mètre et de préférence entre 1.5 et 2.5 mètres (environ entre la moitié et les trois quart de la hauteur totale qui est de l'ordre de 3 à 6 mètres).The length will be at least 1 meter and preferably between 1.5 and 2.5 meters (approximately between half and three quarters of the total height which is of the order of 3 to 6 meters).

On n'affecte pas les performances du poteau global ainsi construit car le choc des voitures est à une hauteur comprise entre 40 cm et 1,00 m c'est à dire un point éloigné de la zone de liaison entre la partie basse et la partie haute. La partie basse doit cependant rester suffisamment longue pour se déformer en grande partie et ainsi absorber de l'énergie.The performance of the overall post thus constructed is not affected because the impact of the cars is at a height of between 40 cm and 1.00 m, ie a point distant from the connection zone between the lower part and the part high. The lower part must however remain long enough to deform largely and thus absorb energy.

Un autre intérêt apparait en utilisant comme partie haute, le mât dit traditionnel qui présente des capacités de déformation moindre car il permet de réutiliser le panneau existant et son système de fixation (souvent une bride).Le personnel n'a donc aucune difficulté à exploiter ces nouveaux poteaux.Another advantage appears by using as the upper part, the so-called traditional mast which has less deformation capacity because it allows to reuse the existing panel and its fastening system (often a flange). The staff has no difficulty in operating these new posts.

Il suffit donc de démonter les panneaux de signalisation, de retirer le mât existant avec un engin de levage, de reposer le nouveau mât conforme à l'invention et de fixer dessus les panneaux.It is therefore sufficient to disassemble the signs, remove the existing mast with a hoist, rest the new mast according to the invention and attach the panels.

Il n'est pas nécessaire de se préoccuper de l'orientation des massifs car la partie haute permet d'orienter le panneau sur 360°.It is not necessary to be concerned about the orientation of the massifs because the high part makes it possible to orient the panel on 360 °.

Pour solidariser la partie haute à la partie basse, on fixe sur l'extrémité du poteau à section polygonale une pièce 6 dite de séparation en forme de plaque ou de fourreau sur laquelle pièce de séparation sera monté un morceau de mât traditionnel .Cette pièce de séparation est utilisée comme moyen de liaison entre les deux morceaux de mât.To secure the upper part to the lower part, is fixed on the end of the polygonal section pole a so-called plate-shaped separation part 6 or sheath on which separation piece will be mounted a piece of traditional mast .This separation piece is used as a connecting means between the two pieces of mast.

Une butée ou une plaque de séparation située à la base du fourreau garantie le fait que lorsque l'on fait usage d'un montage coulissant pour la partie supérieure, la partie coulissante ne pénètre pas dans la partie à section polygonale ce qui affecterait les capacités.An abutment or a separating plate at the base of the sheath assures that when a sliding assembly is used for the upper part, the sliding part does not penetrate the polygonal section which would affect the capabilities .

Selon la construction du poteau, la pièce de séparation et/ou la platine de base seront fixées par soudure ou vis. L'utilisation de vis permet de calibrer la résistance au choc de la liaison partie basse avec la platine ou la plaque de séparation.Depending on the construction of the post, the separating part and / or the base plate will be fixed by welding or screw. The use of screws makes it possible to calibrate the impact resistance of the lower part connection with the plate or the separating plate.

La résistance de la liaison entre les deux parties doit être suffisante pour éviter la séparation des deux tronçons lors de la chute du mât.The strength of the connection between the two parts must be sufficient to avoid the separation of the two sections during the fall of the mast.

Les mâts construits respecteront la norme Européenne EN 12767.The masts built will comply with the European standard EN 12767.

La pièce de séparation permet de lier les deux parties du poteau mais réduit les effets d'une partie sur l'autre qui pourraient modifier le comportement de la partie basse. Cette plaque verrouille la géométrie du haut de la partie basse.The separating part makes it possible to bind the two parts of the post but reduces the effects of one part on the other which could modify the behavior of the lower part. This plate locks the geometry of the top of the bottom part.
