Abstract

The safety barrier is constructed from a series of prefabricated concrete sections (2) with broad bases (3), having metal rings (9, 10) anchored in their ends to receive vertical connecting bolts (11) screwed into plates (12) set in recesses (6) in the base. Joints between sections are covered by inverted U-section caps (13) with side holes (17) for removable fixings (21), and the sides of the sections can be given reflective strips.

Description

La présente invention concerne une barrière de sécurité en béton, pour des voies de circulation routières et autoroutières, la barrière étant composée d'éléments préfabriqués en béton à disposer sur le sol les uns à la suite des autres, et des moyens étant prévus pour assurer la liaison entre éléments de barrière consécutifs. Cette barrière de sécurité peut constituer une séparation provisoire de voies, dans un secteur où sont effectués des travaux tels que réfection ou élargissement de chaussée ; elle peut aussi constituer une séparation définitive, quoique mobile, entre deux voies de circulation.The present invention relates to a safety barrier made of concrete, for road and motorway traffic lanes, the barrier being made up of precast concrete elements to be placed on the ground one after the other, and means being provided to ensure the connection between consecutive barrier elements. This security barrier may constitute a temporary separation of tracks, in a sector where are carried out work such as repairing or widening the road; she can also constitute a definitive, albeit mobile, separation between two lanes.

Des barrières de sécurité de ce genre sont actuellement bien connues, et couramment utilisées. Elles se composent habituellement d'éléments en béton armé de longueur par exemple égale à environ 4 mètres, et de profil normalisé, élargi à sa base. Ces éléments de barrière sont pourvus, à leurs extrémités, d'anneaux métalliques horizontaux au travers desquels sont introduites des tiges métalliques verticales, qui assurent la liaison entre éléments consécutifs.Safety barriers of this kind are currently well known, and commonly used. They usually consist of reinforced concrete elements of length equal for example to about 4 meters, and of standardized profile, widened at its base. These barrier elements are provided, at their ends, with horizontal metal rings at the through which vertical metal rods are introduced, which provide the link between consecutive elements.

Comme on le conçoit aisément, les tiges verticales constituent ici des axes d'articulation, qui autorisent un certain désalignement entre éléments consécutifs pour permettre à la barrière de suivre une ligne courbe, mais qui nuisent à la rigidité de la liaison entre les éléments de barrière, alors que cette rigidité constitue un facteur essentiel pour l'efficacité de la barrière en cas de choc de véhicule.As is easily understood, the vertical rods constitute here articulation axes, which allow a certain misalignment between consecutive elements to allow the barrier to follow a line curve, but which affect the rigidity of the connection between the elements of barrier, whereas this rigidity constitutes an essential factor for the effectiveness of the barrier in the event of a vehicle impact.

Le brevet français n° 2 749 329, du même inventeur, décrit déjà une barrière de sécurité en béton perfectionnée, qui peut être utilisée soit comme séparation provisoire, soit comme séparation définitive, grâce à des poteaux introduits au travers des anneaux des éléments de barrière en béton, ces poteaux assurant la liaison de deux éléments de barrière consécutifs, et simultanément leur ancrage au sol. Toutefois, la rigidité de la liaison entre éléments de barrière consécutifs n'est ici améliorée que dans la mesure où les poteaux de liaison sont ancrés au sol, soit par enfoncement direct, soit par introduction dans des platines spéciales d'ancrage, elles-mêmes fixées au sol.French Patent No. 2,749,329, from the same inventor, describes already an improved concrete safety barrier, which can be used either as temporary separation or as final separation, thanks to posts inserted through the rings of the barrier elements in concrete, these posts ensuring the connection of two barrier elements consecutive, and simultaneously their anchoring to the ground. However, the rigidity of the connection between consecutive barrier elements is only improved here insofar as the connecting posts are anchored to the ground, either by direct insertion, either by introduction into special plates anchor, themselves fixed to the ground.

La présente invention vise à éliminer les inconvénients précédemment exposés, en fournissant une barrière de sécurité améliorée du point de vue de la rigidité de la liaison entre éléments, sans nécessité d'un ancrage au sol, et tout en augmentant la maniabilité et la sécurité de cette barrière.The present invention aims to eliminate the drawbacks previously exposed, providing an improved safety barrier from the point of view of the rigidity of the connection between elements, without necessity ground anchor, and while increasing the maneuverability and safety of this barrier.

A cet effet, l'invention a essentiellement pour objet une barrière de sécurité en béton, du genre ici considéré, avec moyens de liaison entre éléments de barrière consécutifs, comprenant des anneaux métalliques de liaison ancrés aux extrémités desdits éléments de barrière, et des tiges de liaison introduites verticalement au travers des anneaux, cette barrière de sécurité étant caractérisée en ce que, notamment pour la constitution d'une barrière définitive, mais mobile, les moyens de liaison entre éléments de barrière comprennent encore des capots métalliques inférieurs qui prennent place à la jonction de deux éléments de barrière consécutifs, dans des évidements formés sous la base élargie de ces éléments, chaque capot inférieur présentant un trou central d'axe vertical, tandis que les tiges de liaison sont conformées en vis, avec une tête apte à prendre appui sur l'un des anneaux de liaison, et une partie filetée prévue pour être introduite et vissée dans le trou central d'un capot inférieur.To this end, the invention essentially relates to a barrier of concrete safety, of the kind considered here, with means of connection between consecutive barrier elements, comprising metal rings of connection anchored at the ends of said barrier elements, and of the rods bond introduced vertically through the rings, this barrier of security being characterized in that, in particular for the constitution a definitive but mobile barrier, the means of connection between elements barriers still include lower metal covers which take place at the junction of two consecutive barrier elements, in recesses formed under the enlarged base of these elements, each cover lower with a central hole of vertical axis, while the rods of connection are screw-shaped, with a head capable of bearing on one connecting rings, and a threaded part intended to be introduced and screwed into the central hole of a lower cover.

Dans une forme de réalisation préférée de l'invention, les moyens de liaison entre éléments de barrière comprennent aussi des capots supérieurs de section en « U » renversé, prévus pour chevaucher les sommets de deux éléments de barrière consécutifs, à la jonction de ces éléments, des moyens étant prévus pour la fixation latérale démontable des capots supérieurs sur les éléments de barrière.In a preferred embodiment of the invention, the connecting means between barrier elements also include covers inverted U-shaped section superiors, designed to overlap the vertices of two consecutive barrier elements, at the junction of these elements, means being provided for the removable lateral fixing of the upper covers on the barrier elements.

Les évidements, formés sous la base élargie des éléments de barrière pour recevoir les capots inférieurs, sont avantageusement des évidements longitudinaux continus, s'étendant sur toute la longueur de ces éléments de barrière.The recesses, formed under the enlarged base of the elements of barrier to receive the lower covers, are advantageously continuous longitudinal recesses, extending over the entire length of these barrier elements.

Selon une autre caractéristique, les éléments de barrière présentent aussi des rainures longitudinales de sécurité pour manutention, ménagées de part et d'autre de leur partie supérieure étroite, ces rainures étant prolongées vers le haut, aux deux extrémités des éléments de barrière, par des parties évidées recevant les capots supérieurs.According to another characteristic, the barrier elements also have longitudinal safety grooves for handling, formed on either side of their narrow upper part, these grooves being extended upwards, at both ends of the elements of barrier, by hollowed out parts receiving the upper covers.

Dans l'ensemble, la barrière de sécurité objet de l'invention possède les avantages suivants :

  • les moyens de liaison, comprenant les tiges de liaison serrées par vissage sur les capots inférieurs, avec obtention d'une tension verticale, assurent une liaison rigide dans la zone de raccordement de deux éléments de barrière consécutifs, ce qui permet de réaliser une barrière définitive mobile, sans ancrage de celle-ci dans le sol ;
  • la rigidité de la liaison entre les éléments de barrière est encore renforcée, dans le cas où les moyens de liaison sont complétés par des capots supérieurs, qui enveloppent et « pincent » les sommets de ces éléments de barrière ;
  • les capots supérieurs, mis en place, assurent aussi la protection des autres moyens de liaison (anneaux, tiges, capots inférieurs) qui sont situés en dessous ;
  • prenant place dans des parties évidées des éléments en béton, les capots supérieurs sont encastrés et ne forment pas des parties en saillie ou anguleuses qui présenteraient un danger ;
  • la présence d'un évidement longitudinal continu et de rainures longitudinales, sur les éléments de barrière en béton, permet d'alléger ces éléments, avec un gain de poids de l'ordre de 10 % ou plus, ce qui en facilite la manutention, et en réduit les coûts de fabrication et de transport, sans que la résistance de la barrière soit diminuée ;
  • les rainures longitudinales évitent le risque de glissement, sur le béton, des pinces de manutention utilisées lors des opérations de pose, d'enlèvement ou de déplacement des éléments de barrière ;
  • enfin, il reste possible de ne pas utiliser les capots inférieurs et supérieurs, et d'assembler les éléments de barrière par simple introduction verticale d'une tige de liaison dans les anneaux, pour la constitution d'une barrière provisoire délimitant par exemple une zone de chantier.
Overall, the safety barrier object of the invention has the following advantages:
  • the connecting means, comprising the connecting rods tightened by screwing on the lower covers, with obtaining a vertical tension, ensure a rigid connection in the connection area of two consecutive barrier elements, which makes it possible to produce a final barrier mobile, without anchoring it in the ground;
  • the rigidity of the connection between the barrier elements is further reinforced, in the case where the connection means are completed by upper covers, which envelop and "pinch" the tops of these barrier elements;
  • the upper covers, installed, also provide protection for the other connecting means (rings, rods, lower covers) which are located below;
  • taking place in hollow parts of the concrete elements, the upper covers are recessed and do not form protruding or angular parts which would present a danger;
  • the presence of a continuous longitudinal recess and longitudinal grooves, on the concrete barrier elements, makes it possible to lighten these elements, with a weight gain of the order of 10% or more, which facilitates handling, and reduces manufacturing and transport costs, without reducing the resistance of the barrier;
  • the longitudinal grooves avoid the risk of sliding, on the concrete, of the handling clamps used during the operations of installation, removal or displacement of the barrier elements;
  • finally, it remains possible not to use the lower and upper covers, and to assemble the barrier elements by simple vertical introduction of a connecting rod in the rings, for the constitution of a temporary barrier delimiting for example an area site.

De toute façon, l'invention sera mieux comprise à l'aide de la description qui suit, en référence qu dessin schématique annexé représentant, à titre d'exemple, une forme d'exécution de cette barrière de sécurité en béton pour voies routières et autoroutières :

  • Figure 4 est une vue de face, à échelle agrandie, d'un anneau de liaison ;
  • Figure 5 est une vue en coupe longitudinale de cet anneau, suivant V-V de figure 4.
In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of example, an embodiment of this concrete safety barrier for roadways and motorways:
  • Figure 1 is an exploded perspective view of a safety barrier section according to the present invention, showing its various components;
  • Figure 2 is a side view, with partial sections, of the connection zone of two consecutive elements of this safety barrier;
  • Figure 3 is an end view of a barrier element;
  • Figure 4 is a front view, on an enlarged scale, of a connecting ring;
  • FIG. 5 is a view in longitudinal section of this ring, along VV of FIG. 4.

La barrière de sécurité, représentée au dessin, se compose principalement d'éléments de barrière 2 préfabriqués, en béton armé, dont l'un est visible en entier sur la figure 1. Chaque élément de barrière 2 possède une base élargie 3, des flancs inclinés 4 et une partie supérieure 5 relativement étroite, le profil de l'élément 2 étant bien visible sur la figure 3.The safety barrier, shown in the drawing, consists of mainly prefabricated barrier elements 2, in reinforced concrete, of which one is fully visible in Figure 1. Each barrier element 2 has an enlarged base 3, inclined sides 4 and an upper part 5 relatively narrow, the profile of element 2 being clearly visible on the figure 3.

Un évidement longitudinal continu 6 est ménagé, en position médiane, sous la base élargie 3 de l'élément 2. Des rainures longitudinales 7 sont aussi ménagées de part et d'autre de la partie supérieure étroite 5 de l'élément 2, ces rainures 7 étant prolongées vers le haut, comme indiqué en 8, aux deux extrémités de l'élément 2.A continuous longitudinal recess 6 is provided, in position median, under the enlarged base 3 of element 2. Longitudinal grooves 7 are also provided on either side of the narrow upper part 5 of element 2, these grooves 7 being extended upwards, as indicated at 8, at the two ends of element 2.

A chaque extrémité de l'élément de barrière 2 sont prévus deux anneaux de liaison horizontaux 9 et 10, superposés, constitués par des pièces métalliques ancrées dans le béton de l'élément 2.At each end of the barrier element 2 are provided two horizontal connecting rings 9 and 10, superimposed, consisting of metal parts anchored in the concrete of element 2.

Les moyens de liaison entre éléments de barrière 2 comprennent encore, selon l'invention : des tiges de liaison 11, des capots inférieurs 12 et des capots supérieurs 13.The means of connection between barrier elements 2 according to the invention also include: connecting rods 11, cowls lower 12 and upper covers 13.

Chaque tige de liaison 11, réalisée à la manière d'une vis, possède une tête 14 par exemple à six pans dans sa partie supérieure, et un filetage 15 dans sa partie inférieure.Each connecting rod 11, produced in the manner of a screw, has a head 14 for example with a hexagon in its upper part, and a thread 15 in its lower part.

Chaque capot inférieur 12, réalisé en tôle ou par un tronçon de profilé, possède une double paroi horizontale et deux ailes latérales. Un trou taraudé 16 d'axe vertical, complémentaire du filetage 15 de la tige de liaison 11, est ménagé dans la paroi horizontale supérieure du capot 12, au centre de celle-ci.Each lower cover 12, made of sheet metal or by a section of profiled, has a horizontal double wall and two lateral wings. A hole threaded 16 with vertical axis, complementary to the thread 15 of the rod link 11, is formed in the upper horizontal wall of the cover 12, at center of it.

Chaque capot supérieur 13, réalisé lui aussi en tôle ou par un tronçon de profilé, possède une section en forme générale de « U » renversé. Des trous 17 sont percés dans les deux ailes du capot supérieur 13, vers les deux extrémités de ce capot 13.Each upper cover 13, also made of sheet metal or by a section of profile, has a section in the general shape of "U" reversed. Holes 17 are drilled in the two wings of the upper cover 13, towards the two ends of this cover 13.

Les anneaux de liaison 9 et 10 sont avantageusement réalisés selon les figures 4 et 5, avec une double tige métallique 18 d'ancrage dans le béton d'un élément de barrière 2. Sur la partie médiane cintrée de la double tige 18, de part et d'autre de celle-ci, sont soudées deux rondelles métalliques 19 et 20. Ce mode de réalisation conduit à un ensemble véritablement indéformable.The connecting rings 9 and 10 are advantageously made according to Figures 4 and 5, with a double metal rod 18 for anchoring in the concrete of a barrier element 2. On the curved middle part of the double rod 18, on either side thereof, are welded two washers metals 19 and 20. This embodiment leads to a set truly undeformable.

Pour l'assemblage de deux éléments de barrière 2 consécutifs, les extrémités de ces éléments 2 sont rapprochées de manière à aligner leurs anneaux de liaison 9 et 10 respectifs suivant un même axe vertical. De plus, un capot inférieur 12 est placé à la jonction des deux éléments de barrière 2, au niveau du sol dans les évidements longitudinaux 6 respectifs de ces éléments 2. Une tige de liaison 11 est engagée par le haut dans les quatre anneaux 9 et 10 alignés, et cette tige de liaison 11 est vissée, par son filetage 15, dans le trou taraudé 16 du capot inférieur 12. Le serrage de la tige de liaison 11 est poursuivi jusqu'à obtenir une mise en tension suffisante de cette tige 11, dont la tête 14 prend alors appui fermement sur l'anneau 9 supérieur, provoquant une mise en compression des deux éléments de barrière 2 par l'intermédiaire du capot inférieur 12 - voir en particulier la figure 2. La conformation de l'anneau 9, selon les figures 4 et 5, permet à la tête 14 de la tige 11 de prendre appui à plat fortement sur l'une des rondelles 19 ou 20, sans risque de déformation de cet anneau 9 par pliage.For the assembly of two consecutive barrier elements 2, the ends of these elements 2 are brought together so as to align their respective connecting rings 9 and 10 along the same vertical axis. In addition, a lower cover 12 is placed at the junction of the two elements of barrier 2, at ground level in the respective longitudinal recesses 6 of these elements 2. A connecting rod 11 is engaged from above in the four rings 9 and 10 aligned, and this connecting rod 11 is screwed, by its thread 15, in the tapped hole 16 of the lower cover 12. The tightening of the connecting rod 11 is continued until a tensioning is obtained sufficient of this rod 11, the head 14 of which then bears firmly on the upper ring 9, causing compression of the two barrier elements 2 via the bottom cover 12 - see at particularly Figure 2. The configuration of the ring 9, according to Figures 4 and 5, allows the head 14 of the rod 11 to bear flat strongly on one of the washers 19 or 20, without risk of deformation of this ring 9 by folding.

En complément, le capot supérieur 13 est emboíté sur la zone de jonction des deux éléments de barrière 2, en prenant place dans les parties évidées 8 respectives des extrémités de ces éléments 2. Des vis latérales 21 sont introduites au travers des trous 17 du capot supérieur 13, et serrées dans des trous 22 correspondants ménagés dans les parties évidées 8 des deux éléments de barrière 2, pour fixer le capot supérieur 13 à ces éléments 2 et augmenter la rigidité de l'assemblage, tout en protégeant les organes de liaison situés au-dessous.In addition, the upper cover 13 is fitted on the area of junction of the two barrier elements 2, taking place in the respective hollowed out portions 8 of the ends of these elements 2. Screws side 21 are introduced through the holes 17 of the upper cover 13, and clamped in corresponding holes 22 formed in the parts recesses 8 of the two barrier elements 2, for fixing the upper cover 13 to these elements 2 and increase the rigidity of the assembly, while protecting the connecting members located below.

Comme indiqué en 23 sur la figure 1, les flancs inclinés 4 des éléments de barrière 2 reçoivent avantageusement des bandes rétro-réfléchissantes rapportées, par exemple fixées par collage, qui réalisent une signalisation horizontale efficace et durable, homologuée « autoroute ». As indicated at 23 in FIG. 1, the inclined flanks 4 of the barrier elements 2 advantageously receive retro-reflective tapes added, for example fixed by gluing, which achieve a efficient and durable horizontal signage, "highway" approved.

La barrière de sécurité en béton, dont les éléments 2 sont assemblés comme décrit précédemment, constitue notamment une barrière « définitive », laquelle reste toutefois démontable et mobile. A l'aide des mêmes éléments 2, il est aussi possible de réaliser une barrière « provisoire », en réunissant simplement les éléments de barrière 2 au moyen de tiges de liaison 11 introduites au travers des anneaux 9 et 10, sans utiliser les capots inférieurs 12 et supérieurs 13.The concrete safety barrier, whose elements 2 are assembled as described above, in particular constitutes a barrier "Definitive", which however remains removable and mobile. Using the same elements 2, it is also possible to make a barrier "Provisional", by simply joining the barrier elements 2 to the means of connecting rods 11 introduced through the rings 9 and 10, without using the lower 12 and upper 13 covers.

Pour la manutention des éléments de barrière 2, lors de la pose d'une barrière, de son enlèvement ou de son déplacement, on utilise des pinces mécaniques ou hydrauliques qui agrippent lesdits éléments 2 par leurs rainures longitudinales 7, ce qui évite tout glissement dangereux, notamment par temps de pluie ou en cas de gel.For handling barrier elements 2, during installation of a barrier, its removal or its displacement, we use mechanical or hydraulic grippers which grip said elements 2 by their longitudinal grooves 7, which prevents any dangerous sliding, especially in rainy weather or in case of frost.
