Description

La présente invention concerne une glissière de sécurité routière destinée à assurer la sécurité routière de véhicules automobiles sur des axes routiers et à éviter leur sortie de route ainsi qu'un procédé de montage de ladite glissière.The present invention relates to a road safety barrier intended to ensure the road safety of motor vehicles on road axes and to avoid their departure from the road as well as a method of mounting said barrier.

Les glissières de sécurité qui sont constituées de profilés métalliques assemblés par recouvrement partiel et boulonnage et supportés de place en place par des poteaux verticaux, le profilé présentant une rainure centrale dont les ailes sont prolongées par des nervures latérales servant de raidisseurs formant un relief du côté de la chaussée et ayant leur flanc extérieur replié en direction du poteau vertical sont connues. Un exemple de ce type de glissière est plus particulièrement décrit dans le brevet FR-2 641 804.Safety barriers which consist of metal profiles assembled by partial overlapping and bolting and supported from place to place by vertical posts, the profile having a central groove whose wings are extended by lateral ribs serving as stiffeners forming a relief on the side of the roadway and having their outer side folded in the direction of the vertical post are known. An example of this type of slide is more particularly described in patent FR-2,641,804.

On connaît également des glissières de sécurité bois métal dans lesquelles les éléments métalliques servent de liaison aux éléments de la lisse en bois. Ces éléments métalliques peuvent être constitués soit par des éclisses logées dans des évidements ménagés aux extrémités des éléments de la lisse bois comme le décrivent par exemple les brevets FR-2 658 214 et EP-A-0 184 525, soit par des plaques métalliques qui sont disposées à la jonction de deux éléments de lisse adjacents et permettent la liaison lisse/poteau vertical conformément à ce qui est décrit notamment dans le brevet FR-2 650 010. Dans le cas de ce dispositif, il est nécessaire d'avoir des boulons dans un plan sensiblement vertical et de disposer en raison de la forme spécifique de la plaque d'un méplat dans la zone de fixation sur le poteau vertical. De ce fait, on ne met pas à profit toutes les caractéristiques d'élasticité du bois formant la lisse et on retrouve un inconvénient commun à tous les systèmes décrits ci-dessus, inconvénient qui réside dans le fait que la structure métallique est apparente.Wood metal safety barriers are also known in which the metal elements serve as a connection to the elements of the wooden heald. These metallic elements can be constituted either by fishplates housed in recesses formed at the ends of the elements of the wooden heald as described for example by patents FR-2 658 214 and EP-A-0 184 525, or by metal plates which are arranged at the junction of two adjacent heald elements and allow the heald / vertical post connection in accordance with what is described in particular in patent FR-2 650 010. In the case of this device, it is necessary to have bolts in a substantially vertical plane and, because of the specific shape of the plate, have a flat in the area of attachment to the vertical post. Therefore, we do not take advantage of all the elasticity characteristics of the wood forming the heddle and there is a drawback common to all the systems described above, a drawback which lies in the fact that the metallic structure is apparent.

EP-A-0.437.414 décrit une glissière pour axes de circulation à vitesse réduite constituée d'un élément élastiquement déformable alvéolaire disposé en applique sur une lisse métal. Cet élément alvéolaire absorbe ponctuellement de manière non significative l'onde de choc qui est transmise directement à la lisse métallique qui se rompra sous l'effet d'un choc violent du fait qu'elle bénéficie d'aucun élément de protection.EP-A-0.437.414 describes a slide for axes of circulation at reduced speed made up of an elastically deformable cellular element arranged in the surface on a smooth metal. This cellular element absorbs punctually in a non-significant way the shock wave which is transmitted directly to the metal beam which will break under the effect of a violent shock due to the fact that it benefits from no protective element.

Le but de la présente invention est de proposer une glissière de sécurité qui, tout en présentant les avantages liés à l'utilisation d'une lisse à section circulaire, peut être installée sur des axes routiers où la vitesse autorisée est relativement élevée en raison de son architecture particulière qui lui confère une résistance au choc et une solidité exceptionnelles sans nuire à son aspect esthétique.The object of the present invention is to provide a safety barrier which, while having the advantages linked to the use of a heald with circular section, can be installed on road axes where the authorized speed is relatively high due to its particular architecture which gives it exceptional impact resistance and solidity without compromising its aesthetic appearance.

Un autre but de l'invention est de proposer un procédé de montage de la glissière qui soit simple, facile et rapide à mettre en oeuvre de manière à permettre le remplacement aisé d'un élément de lisse ou l'installation de glissières sur une distance importante en un minimum de temps.Another object of the invention is to propose a method of mounting the slide which is simple, easy and quick to implement so as to allow easy replacement of a heald member or the installation of slideways over a distance. important in a minimum of time.

La présente invention concerne à cet effet une glissière de sécurité routière constituée de profilés métalliques assemblés par recouvrement partiel et boulonnage et supportés de place en place par des poteaux verticaux, le profilé présentant une rainure centrale, caractérisée en ce que la rainure centrale du profilé est sensiblement identique au profil d'une lisse horizontale formée d'éléments de lisse en bois mis bout à bout, et venant en appui au fond de ladite rainure centrale et ladite rainure centrale est prolongée sur ses deux bords par un rebord servant notamment de raidisseur replié vers l'arrière dudit profilé.The present invention relates for this purpose to a road safety barrier made up of assembled metal profiles by partial overlapping and bolting and supported from place to place by vertical posts, the profile having a central groove, characterized in that the central groove of the profile is substantially identical to the profile of a horizontal heald formed of wooden heald elements placed end to end, and coming to bear at the bottom of said central groove and said central groove is extended on its two edges by a flange serving in particular as a stiffener folded back from said profile.

Selon une autre caractéristique de l'invention, les éléments de lisse font saillie respectivement au-dessus et en dessous du profilé de manière à le masquer.According to another characteristic of the invention, the heald elements project respectively above and below the profile so as to hide it.

Selon une forme de réalisation préférée de l'invention, les profilés métalliques sont solidarisés aux poteaux verticaux par des moyens de fixation assurant un maintien de l'ensemble à une hauteur quelconque sur le poteau. Ces moyens de fixation sont notamment constitués par un collier de serrage solidarisé directement ou non aux profilés métalliques.According to a preferred embodiment of the invention, the metal profiles are secured to the vertical posts by fixing means ensuring that the assembly is held at any height on the post. These fixing means are in particular constituted by a clamping collar secured directly or not to the metal profiles.

L'invention concerne également un procédé de montage d'une glissière de sécurité, caractérisé en ce qu'on dispose au sol les profilés métalliques en les superposant partiellement, en ce qu'on utilise la rainure centrale desdits profilés comme rail de guidage de la roue d'une machine à battre des pieux, en ce qu'on dispose un poteau vertical en regard de chaque zone de superposition des profilés, en ce qu'on fixe les profilés métalliques sur lesdits poteaux et en ce qu'on solidarise les éléments de la lisse bois à la lisse métallique.The invention also relates to a method of mounting a safety barrier, characterized in that the metal profiles are placed on the ground by partially superimposing them, in that the central groove of said profiles is used as the guide rail of the wheel of a pile driving machine, in that there is a vertical post facing each zone of overlapping of the sections, in that the metal sections are fixed on said posts and in that the elements are secured from the wood beam to the metal beam.

Other characteristics and advantages of the invention will become apparent on reading the following description and the accompanying drawings, which description and drawings are given mainly by way of examples. In these drawings:

Conformément aux figures 1, 2 et 5, la glissière de sécurité routière, objet de l'invention, est constituée de profilés métalliques 2 assemblés par recouvrement partiel et boulonnage et supportés de place en place de préférence au niveau de leur zone de recouvrement par des poteaux verticaux 8. Les profilés métalliques 2 présentent de manière en soi connue, une rainure centrale 2a dont les bords sont prolongés par un rebord 2b servant de raidisseur replié vers l'arrière du profilé en direction du poteau vertical 8. A ces profilés métalliques 2 est associé une lisse en bois 1 continue formée d'éléments de lisse mis bout à bout comme le montre la figure 1. Ces éléments de lisse peuvent affecter une forme quelconque mais ils présenteront de préfé-rence une section circulaire en raison des avantages inhérents à une telle configuration (moments de flexion et de torsion importants). De même, ces éléments de lisse, bien qu'ils puissent être en n'importe quel matériau seront de préférence en bois en raison des caractéristiques d'élasticité du bois qui renforcent l'intérêt de la configuration choisie. En effet, selon la caractéristique principale de l'invention, la rainure centrale 2a du profilé 2 est sensiblement identique au profil des éléments de lisse 1 comme le montre la figure 5 de telle sorte que les éléments de lisse sont couverts sur toute la longueur de leur face latérale arrière par les profilés métalliques et en fait, viennent en appui au fond de ladite rainure. Cette complémentarité des profils peut se traduire conformément à la figure 5 par un rayon de courbure identique du fond de la rainure centrale 2a et de l'élément de lisse 1 lorsqu'on travaille avec des lisses de section circulaire. Bien évidemment toute autre forme de lisse et donc de rainure centrale 2a peut être envisagée. Grâce à cette caractéristique, on obtient une glissière dont les caractéristiques de solidité et de résistance lui permettent d'être installée le long d'axes routiers pour lesquels la vitesse maximum autorisée est importante. De plus, malgré cette solidité importante de la glissière, on ne néglige pas l'aspect esthétique du produit car les éléments de lisse présentent une partie supérieure et inférieure faisant saillie respectivement au-dessus et en dessous des plans horizontaux XX' et YY' sensiblement tangents au flanc extérieur 2c des rebords 2b du profilé 2 de telle sorte que le profilé 2 est complètement masqué par la lisse horizontale 1.In accordance with FIGS. 1, 2 and 5, the road safety barrier, object of the invention, consists of metal sections 2 assembled by partial covering and bolting and supported from place to place preferably at their overlap zone by vertical posts 8. The metal sections 2 have, in a manner known per se, a central groove 2a whose edges are extended by a flange 2b serving as a stiffener folded back towards the rear of the section in the direction of the vertical post 8. To these metal sections 2 is associated with a continuous wooden heald 1 formed of heald elements placed end to end as shown in FIG. 1. These heald elements can have any shape but they will preferably have a circular section because of the advantages inherent in such a configuration (significant bending and twisting moments). Likewise, these heald elements, although they may be of any material, will preferably be made of wood because of the elasticity characteristics of the wood which enhance the advantage of the configuration chosen. Indeed, according to the main characteristic of the invention, the central groove 2a of the profile 2 is substantially identical to the profile of the heald elements 1 as shown in FIG. 5 so that the heald elements are covered over the entire length of their rear side face by the metal profiles and in fact come to bear at the bottom of said groove. This complementarity of the profiles can be translated in accordance with FIG. 5 by an identical radius of curvature of the bottom of the central groove 2a and of the heald element 1 when working with healds of circular section. Obviously any other form of smooth and therefore groove central 2a can be considered. Thanks to this characteristic, a slide is obtained, the solidity and resistance characteristics of which allow it to be installed along road axes for which the maximum authorized speed is important. In addition, despite this significant solidity of the slide, the aesthetic appearance of the product is not overlooked since the heald elements have an upper and lower part projecting respectively above and below the horizontal planes XX 'and YY' substantially tangent to the outer flank 2c of the edges 2b of the profile 2 so that the profile 2 is completely masked by the horizontal rail 1.

Dans un mode de réalisation préféré de l'invention, les extrémités adjacentes des éléments de la lisse 1 de bois sont disposées en regard d'un poteau vertical 8 et sont munies d'au moins un alésage traversant 5 disposé de préférence dans le plan diamétral horizontal de la lisse 1. Afin que l'extrémité du boulon destiné à être introduit à l'intérieur de cet alésage 5 au cours du montage de la glissière ne constitue pas un élément d'accrochage ou de retenue en cas de choc, il est prévu une réservation (non représentée) parallèle à l'axe longitudinal de la lisse 1 et sur toute sa longueur. Cette réservation est très discrète et ne nuit absolument pas à l'esthétique de l'ensemble.In a preferred embodiment of the invention, the adjacent ends of the elements of the wooden stringer 1 are arranged opposite a vertical post 8 and are provided with at least one through bore 5 preferably arranged in the diametrical plane horizontal of the heald 1. So that the end of the bolt intended to be inserted inside this bore 5 during the mounting of the slide does not constitute a hooking or retaining element in the event of impact, it is provided a reservation (not shown) parallel to the longitudinal axis of the heald 1 and over its entire length. This reservation is very discreet and absolutely does not harm the aesthetics of the whole.

Pour permettre la fixation des profilés métalliques 2 et de la lisse 1 sur le poteau vertical 8, on utilise des moyens de fixation qui permettent la fixation de l'ensemble à n'importe quelle hauteur sur le poteau vertical 8. Pour permettre ce réglage en hauteur, on utilise donc de préférence un moyen de fixation constitué d'un collier de serrage 4 qui est, soit directement fixé aux profilés métalliques 2, soit monté solidaire d'un profilé métallique intermédiaire 3 lui-même solidarisé aux profilés 2 par boulonnage. Ces solutions constructives sont représentées dans les figures 1 et 2. Ainsi, dans la figure 1, le collier de serrage 4 est soudé à un profilé métallique 3 dont le profil en section transversale est identique à celui du profilé 2 et dont la longueur est sensiblement égale à la longueur de la zone de superposition des profilés métalliques 2. On obtient ainsi une solidité accrue de l'ensemble en raison de cette triple épaisseur de matière. Le profilé 3 et les profilés 2 sont solidarisés entre eux par boulonnage. C'est pourquoi, on note la présence de deux séries de trois alésages traversants aux extrémités des profilés 2 et deux lumières oblongues (10) de part et d'autre de la soudure du collier 4 sur le profilé 3. Dans la figure 2, il est représenté une autre forme de réalisation du collier de serrage 4. Celui-ci est directement monté sur les profilés 2 grâce à un boulon qui traverse un alésage traversant 11 du collier de serrage et une lumière oblongue des profilés 2.To allow the fixing of the metal sections 2 and of the arm 1 on the vertical post 8, fixing means are used which allow the fixing of the assembly at any height on the vertical post 8. To allow this adjustment in height, use is therefore preferably made of a fixing means consisting of a clamp 4 which is either directly fixed to the metal profiles 2, or mounted integral with an intermediate metal profile 3 itself secured to the profiles 2 by bolting. These constructive solutions are represented in FIGS. 1 and 2. Thus, in FIG. 1, the clamp 4 is welded to a metal profile 3 whose profile in cross section is identical to that of the profile 2 and whose length is substantially equal to the length of the overlapping area of the metal profiles 2. This gives increased strength of the assembly due to this triple thickness of material. Profile 3 and profiles 2 are joined together by bolting. This is why, we note the presence of two series of three through bores at the ends of the sections 2 and two oblong slots (10) on either side of the welding of the collar 4 on the section 3. In FIG. 2, another embodiment of the clamp collar 4 is shown. This is directly mounted on the profiles 2 by means of a bolt which passes through a through bore 11 of the clamp collar and an oblong slot in the profiles 2.

Pour réaliser le montage de l'ensemble, on procède généralement de la manière suivante. On dispose au sol les profilés métalliques en les superposant partiellement au niveau de leur extrémité, on utilise la rainure centrale comme rail de guidage de la roue d'une machine à battre les pieux, on dispose un poteau vertical au niveau de chaque zone de superposition des profilés qui constitue un point de repère, on fixe les profilés métalliques sur lesdits poteaux, on solidarise les éléments de la lisse bois à la lisse métallique.To carry out the assembly of the assembly, one generally proceeds as follows. The metal profiles are placed on the ground by partially superimposing them at their end, the central groove is used as a guide rail for the wheel of a pile-driving machine, there is a vertical post at each superposition zone profiles which constitutes a benchmark, the metal profiles are fixed on said posts, the elements of the wooden rail are joined to the metal rail.

Dans ce montage, aucune prise de dimension n'est nécessaire, ce qui permet un montage aisé et rapide. L'invention décrite s'applique aux glissières de sécurité mais également à toute barrière destinée à délimiter le périmètre d'un lieu.In this assembly, no dimensioning is necessary, which allows easy and rapid assembly. The invention described applies to safety barriers but also to any barrier intended to delimit the perimeter of a place.

Dans l'exemple de la figure 1, les extrémités des profilés métalliques 2 sont équipées de deux séries de trois alésages traversants, chacune des séries étant disposée en regard d'un élément de lisse et l'alésage central 7 de ladite série est destiné à recevoir un boulon qui solidarise la lisse bois en traversant l'alésage 5, les profilés 2 par l'alésage 7 et le collier 4 par traversée de la lumière disposée sur le profilé 3. Les alésages 6 du profilé 2 disposés de part et d'autre de l'alésage 7 sont utilisés au choix pour solidariser les profilés entre eux. Bien évidemment tous ces moyens de fixation sont uniquement cités à titre d'exemple non limitatif.In the example of FIG. 1, the ends of the metal profiles 2 are equipped with two series of three through bores, each of the series being arranged opposite a heald element and the central bore 7 of said series is intended to receive a bolt which secures the smooth wood by crossing the bore 5, the profiles 2 by the bore 7 and the collar 4 by crossing the light disposed on the profile 3. The bores 6 of the profile 2 arranged on either side of the bore 7 are used as desired to secure the profiles together. Obviously all these fixing means are only cited by way of non-limiting example.

La figure 3 représente une variante dans laquelle la glissière est double, c'est-à-dire, disposée de part et d'autre du poteau vertical 8. Dans ce cas, il est nécessaire de fixer le collier de serrage 4 conformément à la figure 4.FIG. 3 represents a variant in which the slide is double, that is to say, arranged on either side of the vertical post 8. In this case, it is necessary to fix the clamp 4 in accordance with the figure 4.
