Description

La présente invention a pour objet une cale destinée à réaliser le montage sur un poteau d'une glissière de sécurité équipant une voie de circulation routière.The present invention relates to a wedge intended for mounting on a post of a safety barrier fitted to a road traffic lane.

Afin d'empêcher les véhicules en perdition de heurter des obstacles agressifs, il est connu, dans les zones dangereuses, de placer le long de la voie de circulation une glissière de sécurité dont le but est de protéger un véhicule en perdition en permettant à celui-ci de glisser le long de la glissière, sans heurter de points durs.In order to prevent vehicles in distress from hitting aggressive obstacles, it is known in dangerous areas to place a safety barrier along the traffic lane, the aim of which is to protect a vehicle in distress by allowing that -this to slide along the slide, without hitting hard points.

Une glissière de sécurité est un élément -profilé disposé parallèlement au sol, et fixée sur celui-ci par l'intermédiaire de poteaux verticaux régulièrement espacés qui sont scellés au sol. Le montage de la glissière sur la tête des poteaux n'est pas réalisé directement, mais avec interposition d'une cale. La fonction de cette cale est tout d'abord d'éloigner la glissière du poteau afin d'éviter ou de réduire les risques d'encastrement d'un véhicule dans un poteau, en cas d'accident. Le but premier est donc de permettre à un véhicule de s'appuyer contre la glissière, voire d'exercer une action sur celle-ci en direction du poteau, sans que le véhicule accroche le poteau, par exemple à l'aide de l'une de ses roues.A safety barrier is a profiled element arranged parallel to the ground, and fixed on the latter by means of regularly spaced vertical posts which are sealed to the ground. The mounting of the slide on the head of the posts is not carried out directly, but with the interposition of a block. The function of this wedge is first of all to move the slide away from the post in order to avoid or reduce the risks of embedding a vehicle in a post, in the event of an accident. The primary purpose is therefore to allow a vehicle to lean against the slide, or even to exert an action thereon in the direction of the post, without the vehicle hooking the post, for example using the one of its wheels.

Les cales les plus anciennes étaient constituées par des blocs de bois.The oldest holds were made of wooden blocks.

Il a ensuite été imaginé de réaliser des cales métalliques, ayant une forme spécialement étudiée pour résister à l'écrasement, assurant ainsi une transmission intégrale de la force résultant du choc du véhicule contre la glissière, vers le support qui se plie à sa base, formant ainsi lui-même amortisseur, la glissière étant pour sa part maintenue à distance du support.It was then imagined to produce metal shims, having a shape specially designed to resist crushing, thus ensuring an integral transmission of the force resulting from the impact of the vehicle against the slide, towards the support which bends at its base, thus forming a shock absorber itself, the slide being kept away from the support.

La glissière ainsi dégagée du support peut pivoter sur son point de fixation, qui est aussi son point d'appui, et rester verticale, bien que le support se plie et s'incline sous l'action de la force résultant du choc. De ce fait, la glissière, poussée par le véhicule, recule selon une trajectoire sensiblement horizontale, bien qu'étant maintenue par le support. La cale non compressible est entraînée vers le sol par le support sur laquelle elle est boulonnée, alors que la glissière recule horizontalement, bien qu'elle soit fixée sur la cale par un autre boulon.The slide thus released from the support can pivot on its fixing point, which is also its fulcrum, and remain vertical, although the support bends and tilts under the action of the force resulting from the shock. As a result, the slide, pushed by the vehicle, moves back along a substantially horizontal trajectory, although it is held by the support. The non-compressible wedge is driven towards the ground by the support on which it is bolted, while the slide moves back horizontally, although it is fixed on the wedge by another bolt.

Il en résulte donc un mouvement de rotation et d'arrachement de la cale vis-à-vis du support. Cet arrachement est favorisé grâce au surdimensionnement du trou ménagé dans la cale, qui est traversé par un boulon de fixation sur le support. Ainsi, après que la glissière ait normalement reculée à l'horizontal, elle est tirée vers le sol par le poteau-support, qui se plie sous l'action du choc. La cale se désolidarise alors du support par "déboutonnage" du boulon qui passe au travers du trou de fixation ménagé dans la cale, libérant ainsi celle-ci et la glissière qui peut continuer sa trajectoire horizontale, le poteau-support pouvant alors se plaquer librement au sol.This therefore results in a rotation and tearing movement of the wedge with respect to the support. This tearing is favored thanks to the oversizing of the hole made in the wedge, which is crossed by a fixing bolt on the support. Thus, after the slide has normally moved back to the horizontal, it is pulled towards the ground by the support post, which bends under the action of the shock. The wedge is then detached from the support by "unbuttoning" the bolt which passes through the fixing hole made in the wedge, thus releasing the latter and the slide which can continue its horizontal trajectory, the support post can then be pressed freely on the ground.

Le véhicule qui déforme la glissière, vient s'encastrer dans celle-ci qui assure sa retenue, cette retenue étant favorisée par le fait que la glissière peut continuer à se déformer sans être tirée au sol. En effet, si la glissière était tirée vers le sol par les poteaux-supports, le véhicule pourrait sans peine la franchir, et quitter la voie de circulation avec le risque qu'il y a de heurter un point dur, ou de faire une chute hors de la route.The vehicle which deforms the slide, comes to be embedded therein which ensures its retention, this retention being favored by the fact that the slide can continue to deform without being pulled to the ground. Indeed, if the slide was pulled towards the ground by the support posts, the vehicle could easily cross it, and leave the lane with the risk that there is to strike a hard point, or to make a fall off the road.

Les cales actuellement utilisées sont des pièces mécanosoudées, comportant deux parties principales en forme d'étrier, qui sont assemblées l'une à l'autre. La première partie qui est destinée à être fixée sur le poteau-support est constituée par un étrier d'axe vertical. La seconde partie qui est destinée à être fixée par la glissière, est constituée par un étrier d'ouverture horizontale, dont les extrémités libres des ailes viennent s'encastrer à l'intérieur du premier étrier, ces deux ailes étant divergentes, et s'écartant depuis la partie centrale de fixation sur la glissière, vers la partie centrale de l'autre étrier destinée à la fixation sur le poteau-support. Les deux ailes de la seconde partie en forme d'étrier sont symétriques par rapport à un plan horizontal.The wedges currently used are mechanically welded parts, comprising two main stirrup-shaped parts, which are assembled to one another. The first part which is intended to be fixed on the support post consists of a bracket with a vertical axis. The second part which is intended to be fixed by the slide, is constituted by a horizontal opening stirrup, the free ends of the wings of which are fitted inside the first stirrup, these two wings being divergent, and s' spreading from the central fixing part on the slide, towards the central part of the other bracket intended for fixing on the support post. The two wings of the second stirrup-shaped part are symmetrical with respect to a horizontal plane.

Les cales de ce type présentent des inconvénients d'ordre économique, puisqu'il s'agit de réaliser deux pièces séparées qui sont assemblées l'une à l'autre par soudage. En outre, ces pièces n'étant pas empilables, sont stockées et livrées en vrac, de telle sorte qu'un certain nombre d'entre elles est toujours perdu au cours des différentes phases de manutention. Enfin, ces cales sont lourdes, et l'accès à la boulonnerie est difficile, ce qui augmente le temps d'intervention lors de la pose.Wedges of this type have economic disadvantages, since it involves making two separate parts which are joined to one another by welding. In addition, these parts are not stackable, are stored and delivered in bulk, so that a certain number of them is always lost during the various handling phases. Finally, these wedges are heavy, and access to the bolts is difficult, which increases the intervention time during installation.

Il convient également de noter que le fait que ces cales présentent une ouverture horizontale se traduit, en période hivernale, par une rétention de neige ou de glace susceptible de détériorer la glissière, ainsi que par une rétention d'eau ou d'agents de traitement des chaussées en vue d'éviter le verglas pouvant favoriser la corrosion des cales et des glissières, notamment lorsque le traitement de surface qu'ont subi ces pièces commence à se dégrader.It should also be noted that the fact that these wedges have a horizontal opening results, in winter, in a retention of snow or ice likely to deteriorate the slide, as well as in a retention of water or treatment agents. pavements to avoid ice that can promote corrosion of holds and slides, in particular when the surface treatment that these parts have undergone begins to deteriorate.

Le but de l'invention est de remédier à ces inconvénients en fournissant une cale pour le montage d'une glissière de sécurité sur un poteau-support possèdant une excellente résistance à l'écrasement, permettant un "déboutonnage" de la cale vis-à-vis du poteau-support, lorsque la glissière a reculé vers l'extérieur de la chaussée d'une valeur supérieure à une valeur prédéterminée sous l'action d'un choc, susceptible d'être plus légère, de fabrication plus aisée, de colisage plus pratique que les cales traditionnelles, et évitant la rétention de neige, de glace ou d'humidité.The object of the invention is to remedy these drawbacks by providing a wedge for mounting a safety barrier on a support post having excellent crushing resistance, allowing "unbuttoning" of the wedge with respect to - screw of the support post, when the slide has moved back towards the outside of the roadway by a value greater than a predetermined value under the action of an impact, likely to be lighter, easier to manufacture, more practical packing than traditional holds, and avoiding the retention of snow, ice or humidity.

A cet effet, la cale qu'elle concerne, est constituée par une pièce tubulaire d'ouverture verticale comportant deux parois parallèles destinées respectivement à l'appui et à la fixation sur un poteau-support et sur une glissière de sécurité reliées par deux ailes divergent depuis la paroi de fixation sur le poteau vers la paroi de fixation sur la glissière, des moyens de renfort étant prévus pour assurer la résistance à l'écrasement.For this purpose, the wedge which it concerns, is constituted by a tubular piece of vertical opening comprising two parallel walls intended respectively for the support and for the fixing on a support post and on a safety barrier connected by two wings. diverge from the fixing wall on the post towards the fixing wall on the slide, reinforcement means being provided to ensure resistance to crushing.

Cette structure permet d'obtenir une pièce sensiblement plus légère que les cales traditionnelles, d'un prix de revient moins élevé, éliminant toute surface portante de rétention de la neige ou de la glace, permettant l'écoulement des eaux et des liquides de protection des chaussées, et offrant la possibilité de recevoir, placé verticalement à l'intérieur de l'arcade, un poteau ou similaire à usage de signalisation provisoire.This structure makes it possible to obtain a piece that is significantly lighter than traditional wedges, at a lower cost price, eliminating any bearing surface for retaining snow or ice, allowing the flow of water and protective liquids. pavements, and offering the possibility of receiving, placed vertically inside the arch, a post or similar for use as temporary signage.

Selon une caractéristique de l'invention, en position montée de cette cale, son bord supérieur est situé dans un plan sensiblement perpendiculaire à l'axe du poteau-support et son bord inférieur est incliné de bas en haut et du poteau-support vers la glissière, la paroi de la cale destinée à la fixation sur le poteau-support comportant un trou pour le passage d'un boulon, ménagé à proximité du bord supérieur horizontal. Il en résulte que cette cale est dissymétrique, puisque son bord supérieur est horizontal et que son bord inférieur est incliné. Il est à noter que le fait que le bord supérieur soit horizontal ne nuit en aucun cas à la résistance de la cale, puisque c'est la partie de celle-ci qui est située en-dessous du trou de fixation sur le poteau-support qui joue un rôle actif lors de la déformation de l'ensemble sous l'impact d'un véhicule.According to a characteristic of the invention, in the mounted position of this wedge, its upper edge is situated in a plane substantially perpendicular to the axis of the support post and its lower edge is inclined from bottom to top and from the support post towards the slide, the wall of the shim intended for attachment to the support post having a hole for the passage of a bolt, formed near the horizontal upper edge. As a result, this wedge is asymmetrical, since its upper edge is horizontal and its lower edge is inclined. It should be noted that the fact that the upper edge is horizontal does not in any way affect the resistance of the shim, since it is the part of the latter which is located below the fixing hole on the support post. which plays an active role during the deformation of the assembly under the impact of a vehicle.

En outre, cette forme dissymétrique de la cale permet, lors du stockage et du transport des cales, de disposer celles-ci tête bêche, ce qui facilite le colisage sous une forme parallélépipèdique.In addition, this asymmetrical shape of the wedge allows, during storage and transport of the wedges, to arrange them head to tail, which facilitates packing in a parallelepiped form.

Selon une forme d'exécution, les moyens de renfort assurant la résistance à l'écrasement sont constitués par des nervures horizontales ménagées au moins dans les deux ailes reliant les parois de fixation respectivement sur le poteau-support et sur la glissière.According to one embodiment, the reinforcing means ensuring the resistance to crushing consist of horizontal ribs formed at least in the two wings connecting the fixing walls respectively on the support post and on the slide.

Selon une autre forme d'exécution, les moyens de renfort assurant la résistance à l'écrasement sont constitués par un fer plat reliant les deux ailes formant jambages, et s'étendant sur une partie de la profondeur de la cale. Ces deux moyens peuvent éventuellement être combinés, et les nervures peuvent également être mises à profit, dans la mesure où elles sont ménagées sur les parois prenant appui contre le poteau-support et contre la glissière, pour assurer un blocage en rotation des écrous de fixation.According to another embodiment, the reinforcing means ensuring the resistance to crushing consist of a flat iron connecting the two wings forming legs, and extending over part of the depth of the wedge. These two means can optionally be combined, and the ribs can also be used, insofar as they are provided on the walls bearing against the support post and against the slide, to ensure a locking in rotation of the fixing nuts. .

Cette cale peut être réalisée à partir d'un élément unique qui est replié sur lui-même et fermé par soudure, ou au contraire être obtenue à partir de deux éléments, dont l'un au moins forme une arcade dont les extrémités libres sont reliées par l'autre élément, fixé sur le premier par soudage.This wedge can be made from a single element which is folded back on itself and closed by welding, or on the contrary can be obtained from two elements, at least one of which forms an arch, the free ends of which are connected by the other element, fixed on the first by welding.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant à titre d'exemple non limitatif, une forme d'exécution de cette cale :

  • Figure 1 est une vue en perspective représentant un tronçon de glissière de sécurité, ainsi que deux poteaux destinés à recevoir cette glissière ;
  • Figure 2 est une vue en coupe par un plan vertical et transversal à la glissière de cette dernière en position fixée sur un poteau-support avec interposition d'une cale ;
  • Figure 3 est une vue en perspective d'une cale selon l'invention ;
  • Figure 4 est une vue de côté de plusieurs cales disposées tête bêche en position de stockage.
In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing, representing by way of nonlimiting example, an embodiment of this wedge:
  • Figure 1 is a perspective view showing a section of safety barrier, as well as two posts intended to receive this slide;
  • Figure 2 is a sectional view through a vertical plane and transverse to the slide of the latter in the fixed position on a support post with interposition of a wedge;
  • Figure 3 is a perspective view of a wedge according to the invention;
  • Figure 4 is a side view of several wedges arranged head to tail in the storage position.

La figure 1 représente une glissière de sécurité 2 constituée de façon connue par un profilé nervuré longitudinalement. Cette glissière de sécurité est destinée à être fixée sur des poteaux verticaux 3 fixés au sol à une distance déterminée les uns des autres. La fixation de la glissière sur chaque poteau 3 est réalisée avec interposition de cales 4. Chaque cale est constituée par une pièce tubulaire comportant une ouverture verticale 5. Cette pièce comprend une paroi 6 d'appui et de fixation contre un poteau 3, ainsi qu'une paroi 7 d'appui et de fixation de la glissière 2.Figure 1 shows a safety barrier 2 constituted in a known manner by a longitudinally ribbed profile. This safety barrier is intended to be fixed on vertical posts 3 fixed to the ground at a determined distance from each other. The fixing of the slide on each post 3 is carried out with the interposition of shims 4. Each shim is constituted by a tubular part having a vertical opening 5. This part comprises a wall 6 for support and fixing against a post 3, as well as a wall 7 for supporting and fixing the slide 2.

Comme montré au dessin, le bord supérieur 8 de la cale 4 est situé dans un plan sensiblement perpendiculaire à l'axe du poteau-support, tandis que son bord inférieur 9 est incliné de bas en haut et du poteau-support 3 vers la glissière 2. La paroi 6 destinée à la fixation sur le poteau-support 3 comporte un trou 10 pour le passage d'un boulon 12, situé à proximité du bord supérieur horizontal 8. Pour sa part, la paroi 7 comporte trois trous 13 disposés selon une ligne horizontale pour réaliser la fixation de la glissière par l'intermédiaire de boulons 14.As shown in the drawing, the upper edge 8 of the wedge 4 is located in a plane substantially perpendicular to the axis of the support post, while its lower edge 9 is inclined from bottom to top and of the support post 3 towards the slide 2. The wall 6 intended for fixing to the support post 3 has a hole 10 for the passage of a bolt 12, located near the horizontal upper edge 8. For its part, the wall 7 has three holes 13 arranged according to a horizontal line for fixing the slide by means of bolts 14.

Comme montré au dessin, la cale 4 comporte plusieurs nervures horizontales 15, en l'occurence trois séries de nervures décalées verticalement les unes par rapport aux autres, données à titre d'exemple.As shown in the drawing, the wedge 4 has several horizontal ribs 15, in this case three series of ribs offset vertically with respect to each other, given by way of example.

Ces nervures visent à assurer une rigidité suffisante à la cale 4 pour éviter son écrasement sous l'effet d'un choc exercé par un véhicule contre la glissière 2.These ribs aim to provide sufficient rigidity to the wedge 4 to prevent it from being crushed under the effect of an impact exerted by a vehicle against the slide 2.

Dans la forme d'exécution représentée au dessin, la cale est réalisée à partir d'une seule pièce métallique pliée, et fermée sur elle-même par une soudure 16.In the embodiment shown in the drawing, the shim is produced from a single folded metal part, and closed on itself by a weld 16.

La forme des cales 4 permet, comme montré à la figure 4, leur stockage tête bêche, ce qui facilite ce stockage ainsi que le colisage pour l'expédition sur le chantier.The shape of the wedges 4 allows, as shown in Figure 4, their head to tail storage, which facilitates this storage as well as packing for shipping to the site.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant une pièce formant cale d'une exceptionnelle rigidité, d'un prix de revient modéré, offrant une grande simplicité de stockage et de colisage, ainsi qu'une mise en oeuvre très simple compte tenu des facilités d'accès au boulon de fixation sur les poteaux-supports et sur les glissières.As is apparent from the above, the invention brings a great improvement to the existing technique by providing a piece forming a shim of exceptional rigidity, at a moderate cost price, offering great simplicity of storage and packaging, as well that a very simple implementation given the ease of access to the fixing bolt on the support posts and on the rails.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de cette cale décrite ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes de réalisation.As it goes without saying, the invention is not limited to the sole embodiment of this wedge described above by way of example, on the contrary it embraces all the variant embodiments thereof.

C'est ainsi, notamment, que la pièce constitutive de la cale pourrait être réalisée en deux parties, par exemple de section en U assemblées l'une à l'autre par soudage, ou encore que la rigidification de la pièce pourrait être obtenue par exemple par un plat reliant les deux ailes du jambage, et/ou un bord plié sur les parois 6 et 7, sans que l'on sorte pour autant du cadre de l'invention.Thus, in particular, that the component part of the wedge could be made in two parts, for example of U-shaped section assembled to each other by welding, or that the stiffening of the part could be obtained by example by a flat connecting the two wings of the jamb, and / or a folded edge on the walls 6 and 7, without departing from the scope of the invention.
