Description

L'invention concerne un dispositif de protection et de visualisation destiné à être adapté sur des séparateurs de voies en béton mis en place sur route et autoroute, séparateurs du type réalisé par des machines à coffrage glissant.The invention relates to a protection and display device intended to be adapted to concrete lane separators installed on roads and motorways, separators of the type produced by machines with sliding formwork.

On connaît déjà des techniques de coulage de séparateurs de voies en béton par machine à coffrage glissant. Les profils qui sortent derrière la machine sont toujours identiques à quelques millimètres près, les cotes ayant été normalisées. Il existe ainsi des séparateurs standards désignés par la dénomination "DBA" signifiant double béton adhérent et de séparateurs désignés par "GBA" signifiant glissière de béton adhérent.Techniques for pouring concrete lane separators are already known by a sliding formwork machine. The profiles coming out behind the machine are always identical to a few millimeters, the dimensions having been standardized. There are thus standard separators designated by the name "DBA" meaning double adherent concrete and separators designated by "GBA" meaning adhesive concrete slide.

Les séparateurs en béton sont réalisés sans joint préformé de telle sort que des fissurations relativement anarchiques apparaissent au bout d'un certain temps. Ces fissures sont relativement importantes tous les dix ou quinze mètres tandis que de petites fissures se produisent tous les trois ou quatre mètres.Concrete separators are made without a preformed joint so that relatively anarchic cracks appear after a certain time. These cracks are relatively large every ten or fifteen meters while small cracks occur every three or four meters.

Il existe en Europe un grand nombre de réalisations de tels séparateurs de voies en béton. Cependant, la pratique a révélé que la couleur grise des séparateurs les rend peu visibles la nuit. On a donc cherché à matérialiser visuellement la partie supérieure du séparateur, de telle sorte oue l'automobiliste puisse mieux se rendre compte de l'existence de ces séparateurs de voies sur l'autoroute où il roule.There are a large number of constructions in Europe of such concrete track separators. However, practice has shown that the gray color of the dividers makes them barely visible at night. We therefore sought to visually materialize the upper part of the separator, so that the motorist can better realize the existence of these lane separators on the highway where he drives.

On connaît différents systèmes mis en place actuellement. Ils consistent à coller sur le béton des plots réflectorisants ou bien à sceller dans le béton des dispositifs réflectorisants verticaux qui coûtent très cher.We know different systems currently in place. They consist in sticking on the reflective pads or on the concrete to seal vertical reflective devices which are very expensive.

En outre, le séparateur de voies en béton présente une hauteur par rapport au sol d'environ 80 cm. Cette hauteur permet parfois l'extinction visuelle des phares de voitures roulant en sens contraire pour le conducteur qui longe le séparateur de voies en béton. Cependant, dans la majorité des cas, ces séparateurs ne sont pas assez hauts pour occulter les lumières des phares de voitures roulant en sens contraire.In addition, the concrete track separator has a height from the ground of about 80 cm. This height sometimes allows the headlights of cars driving in opposite directions to be visually turned off for the driver who runs alongside the concrete lane separator. However, in most cases, these dividers are not high enough to obscure the lights of the headlights of oncoming cars.

Les systèmes anti-éblouissant actuellement réalisés sont d'un prix de revient très onéreux et sont dangereux car ils sont susceptibles de se casser. Ces dispositifs sont constitués notamment de filets tendus sur des supports métalliques ou bien de lames verticales posées et scellées sur la partie supérieure des séparateurs de voies en béton.The anti-dazzle systems currently produced are very expensive and are dangerous because they are liable to break. These devices consist in particular of nets stretched over metal supports or of vertical blades placed and sealed on the upper part of the concrete track separators.

La présente invention a pour but de remédier à ces inconvénients et se propose de créer un dispositif de protection et de visualisation destiné à être adapté sur des séparateurs de voies en béton, d'un prix de revient relativement faible, d'un montage facile et permettant non seulement la protection des fissures du séparateur de voies en béton, mais encore une meilleure matérialisation de la ligne supérieure du séparateur de voies en béton, d'où une plus grande sécurité pour l'automobiliste.The object of the present invention is to remedy these drawbacks and proposes to create a protection and display device intended to be adapted to concrete track separators, of a relatively low cost price, of easy assembly and allowing not only the protection of cracks in the concrete lane separator, but also a better materialization of the upper line of the concrete lane separator, hence greater safety for the motorist.

En outre, la présente invention a pour but de créer un dispositif de protection et de visualisation des séparateurs de voies en béton permettant d'occulter les lumières des voitures roulant en sens inverse.In addition, the present invention aims to create a protection device and visualization of concrete lane dividers to obscure the lights of cars traveling in opposite directions.

A cet effet, l'invention concerne un dispositif de protection et de visualisation destiné à être adapté sur des séparateurs de voies en béton mis en place sur route au autoroute séparateurs du type réalisé par des machines à coffrage glissant, dispositif caractérisé en ce qu'il est constitué d'au moins une gouttière de protection et de visualisation s'adaptant sur la partie supérieure du séparateur, le profil en section de la gouttière étant de forme correspondante à la forme de l'arête supérieure du séparateur de voies en béton.To this end, the invention relates to a protection and display device intended to be adapted to concrete lane dividers installed on the highway to highway separators of the type produced by machines with sliding formwork, device characterized in that it consists of at least one protection and display gutter fitting onto the upper part of the separator, the section profile of the gutter being of shape corresponding to the shape of the upper edge of the concrete channel separator.

La gouttière permet de protéger les petites fissures qui se produisent dans le séparateur de voies en béton contre l'infiltration de l'eau, et, par conséquent, contre le gel en hiver. En outre, cette gouttière, généralement de couleurs diverses, permet de matérialiser la ligne supérieure du séparateur.The gutter helps protect small cracks that occur in the concrete lane separator against water infiltration, and therefore against frost in winter. In addition, this gutter, generally of various colors, makes it possible to materialize the upper line of the separator.

Suivant une autre caractéristique de l'invention, la goutière présente une forme générale de U.According to another characteristic of the invention, the gutter has a general shape of U.

Suivant une autre caractéristique de l'invention, la gouttière est fixée sur le séparateur de voies en béton par collage, il en résulte une très grande facilité de montage.According to another characteristic of the invention, the gutter is fixed to the concrete track separator by gluing, this results in very great ease of assembly.

Bien entendu, on pourrait, sans sortir du cadre de l'invention, utiliser d'autres moyens de montage, en particulier le clouage au pistolet (spittage).Of course, one could, without departing from the scope of the invention, use other mounting means, in particular gun nailing (spitting).

Suivant une autre caractéristique, les flancs de la gouttière servent de supports à des bandes réflectorisantes de la lumière.According to another characteristic, the sides of the gutter serve as supports for reflective strips of light.

Ceci permet de mieux visualiser le séparateur de voies en béton.This allows a better view of the concrete track separator.

Suivant une autre caractéristique de l'invention, la gouttière est surmontée d'une plaque déflectrice parallélépipédique, l'un des champs longitudinaux de la plaque étant disposé dans le prolongement de l'axe médian vertical du séparateur de voies.According to another characteristic of the invention, the gutter is surmounted by a parallelepipedal deflecting plate, one of the longitudinal fields of the plate being arranged in the extension of the vertical median axis of the channel separator.

La plaque déflectrice permet notamment d'obturer suffisamment les lumières des véhicules qui roulent en sens contraire, évitant ainsi d'aveugler les automobilistes.The deflector plate in particular makes it possible to sufficiently close the lights of vehicles traveling in opposite directions, thus avoiding blinding motorists.

Suivant une autre caractéristique de l'invention, la plaque déflectrice est pourvue de nervures de rigidification.According to another characteristic of the invention, the deflector plate is provided with stiffening ribs.

Suivant une autre caractéristique de l'invention, les orifices de la plaque déflectrice sont des fentes.According to another characteristic of the invention, the orifices of the deflector plate are slots.

Les orifices et les fentes prévus dans la plaque déflectrice permettent de mieux résister en laissant passer l'air ainsi que les débris entraînés par le vent.The orifices and slots provided in the deflector plate allow better resistance by letting air and debris carried by the wind pass.

Suivant une autre caractéristique de l'invention, les orifices de la plaque déflectrice sont déterminés par des lames en forme de persiennes.According to another characteristic of the invention, the orifices of the deflector plate are determined by blades in the form of louvers.

La présente invention sera mieux comprise à l'aide d'un mode de réalisation du dispositif de protection et de visualisation conforme à l'invention, représenté schématiquement, à titre d'exemple non limitatif, sur les dessins ci-joints, dans lesquels:

  • la figure 1 est une vue en perspective d'un premier mode de réalisation du dispositif de protection et de visualisation mis en place sur un séparateur de voies en béton,
  • la figure 2 est une vue en perspective d'un second mode de réalisation du dispositif de protection et de visualisation,
  • la figure 3 est un troisième mode de réalisation du dispositif de protection et de visualisation.
The present invention will be better understood using an embodiment of the protection and display device according to the invention, shown diagrammatically, by way of nonlimiting example, in the attached drawings, in which:
  • FIG. 1 is a perspective view of a first embodiment of the protection and display device installed on a concrete track separator,
  • FIG. 2 is a perspective view of a second embodiment of the protection and display device,
  • Figure 3 is a third embodiment of the protection and display device.

Selon la figure 1, le dispositif de protection et de visualisation 1 est constitué d'une gouttière 2. Le p _:fil de cette gouttière, vu en section, est de forma correspondante à la forme de l'arête supérieure 3 du séparateur de voies en béton 4. Suivant ce mode de réalisation particulier, le séparateur de voies en béton est du type désigné par l'expression (DBA) signifiant double béton adhérent. Le séparateur de voies en. béton 4 est réalisé à l'aide d'une machine à coffrage glissant. Un tel séparateur est réalisé sans joint préformé de telle sorte qu'au bout d'un certain temps apparaissent d'importantes fissures 5 environ tous les dix ou quinze mètre, tandis que dans la partie supérieure 3, se produisent de petites fissures 6. La gouttière en forme générale de U s'adapte sur l'arête supérieure 3 du séparateur 4. Elle protège le séparateur 4 contre les infiltrations d'eau dans les fissures 5, 6 et, par conséquent, contre le gel. La gouttière 2 est fixée sur l'arête 3 par des points de collage. En outre, les flancs 7 de la gouttière 2 servent de supports à des bandes réflectorisantes de la lumière. Ceci permet la métérialisation de la ligne supérièure de séparateur de voies 4. La gouttière 2, suivant ce mode de réalisation, est réalisée en un matériau tel que du chlorure de polyvinyl qui est une matière plastique bon marché. La gouttière 2 est réalisée par extrusion et peut être réalisée suivant des coloris différents. En principle, la couleur retenue est la couleur blanche, mais il est possible également de colorer les gouttières en vert et en rouge ou bien de faire alterner ces différentes couleurs suivant la demande.According to Figure 1, the protection and display device 1 consists of a gutter 2. The p _ : wire of this gutter, seen in section, is of forma corresponding to the shape of the upper edge 3 of the separator concrete tracks 4. According to this particular embodiment, the concrete track separator is of the type designated by the expression (DBA) meaning double adherent concrete. The channel separator in. Concrete 4 is produced using a sliding formwork machine. Such a separator is made without a preformed joint so that after a certain time large cracks appear 5 approximately every ten or fifteen meters, while in the upper part 3, small cracks occur. gutter in general U shape fits on the upper edge 3 of the separator 4. It protects the separator 4 against water infiltration in the cracks 5, 6 and, consequently, against freezing. The gutter 2 is fixed to the edge 3 by bonding points. In addition, the sides 7 of the gutter 2 serve as supports for reflective strips of light. This allows the meterization of the upper line of track separator 4. The gutter 2, according to this embodiment, is made of a material such as polyvinyl chloride which is an inexpensive plastic material. The gutter 2 is produced by extrusion and can be produced in different colors. In principle, the chosen color is white, but it is also possible to color the gutters in green and red or to alternate these different colors depending on demand.

Il est possible également de coller des bandes réflectorisantes sur le matériau synthétique de la gouttière 2, ce qui est nettement plus facile que d'effectuer la même opération sur du béton; en effet, le collage dans ce dernier cas est extrêmement difficile. La gouttière 2 matérialise mieux la ligne supérieure du séparateur de voies 4, les véhicules circulant sur des voies en sens inverse suivant les flèches F et F',It is also possible to stick reflective strips on the synthetic material of the gutter 2, which is much easier than performing the same operation on concrete; indeed, bonding in the latter case is extremely difficult. The gutter 2 better materializes the upper line of the lane separator 4, the vehicles traveling on lanes in the opposite direction according to the arrows F and F ′,

En outre, la gouttière 2 est surmontée d'une plaque déflectrice 8. Cette plaque déflectrice est de forme générale parallèlèpipédique, l'un des champs 9 de la plaque 8 étant disposé dans le prolongement de l'axe médian X-Y vertical du séparateur de voies 4. La plaque déflectrice 8 est réalisée à partir d'un feuille de matériau synthétique telle que chlorure de polyvinyl. La plaque déflectrice 8 est pourvue de nervures 10 de rigidification résultant de l'extrusion.In addition, the gutter 2 is surmounted by a deflecting plate 8. This deflecting plate is of generally parallelepipedal shape, one of the fields 9 of the plate 8 being arranged in the extension of the vertical median axis XY of the channel separator 4. The deflector plate 8 is produced from a sheet of synthetic material such as polyvinyl chloride. The deflector plate 8 is provided with stiffening ribs 10 resulting from the extrusion.

En outre, la plaque déflectrice 8 est pourvue d'orifices circulaires 11 disposés en quinconce. Il est possible de prévoir des orifices de formes autres que circulaires, tels que par exemple des orifices polygonaux ou des fentes etc. La disposition de ces orifices est également laissée au choix de la demande. Les orifices ont pour but notamment de laisser passer l'air et les débris entraînés par le vent, ce qui permet d'obtenir une meilleure résistance et une usure moins rapide. En outre, les plaques déflectrices 8 obturent suffisamment les lumières des véhicules circulant en sens contraire de manière à éviter au conducteur d'être ébloui ou aveuglé. En effet, dans ce cas, la seule vision des lumières qui subsiste pour le conducteur est une vision latérale on aveuglante.In addition, the deflector plate 8 is provided with circular orifices 11 staggered. It is possible to provide orifices of shapes other than circular, such as for example polygonal orifices or slots etc. The arrangement of these orifices is also left to the choice of the request. The orifices are intended in particular to allow air and debris entrained by the wind to pass, which makes it possible to obtain better resistance and less rapid wear. In addition, the deflector plates 8 sufficiently close the lights of vehicles traveling in the opposite direction so as to avoid the driver from being dazzled or blinded. Indeed, in this case, the only vision of the lights that remains for the driver is a blinding or lateral vision.

La hauteur des plaques déflectrices 8 est choisie en fonction de la nature du terrain où est installé le séparateur de voies en béton.The height of the deflector plates 8 is chosen according to the nature of the terrain where the concrete track separator is installed.

La gouttière 2 et la plaque défléctrice 8 forment un élément monobloc modulaire dont la longueur peut être de un, deux ou trois mètres, de façon à faciliter le transport et la mise en place, tout en permettant de suivre les virages ou les déformations des profils en lông. Chaque élément monobloc modulaire 12, 13 formé chacun d'une gouttière 2 surmontée d'une plaque déflectrice 8, est pourvu à l'une de ses extrémités de découpes particulières non représentées sur cette figure pour la fixation par chevauchement de deux gouttières 2 successives ou de deux éléments monoblocs modulaires 12, 13 successifs. Le chevauchement d'un premier élément 12 sur le second élément 13 est effectué dans le sens de la descente pour que l'eau ne puisse pas pénétrer entre deux éléments 12, 13 successifs.The gutter 2 and the deflector plate 8 form a modular monobloc element the length of which can be one, two or three meters, so as to facilitate transport and installation, while making it possible to follow the turns or the deformations of the profiles. in lông. Each modular monobloc element 12, 13 each formed by a gutter 2 surmounted by a deflector plate 8, is provided at one of its ends with specific cutouts not shown in this figure for the fixing by overlapping of two successive gutters 2 or of two successive modular monoblock elements 12, 13. The overlapping of a first element 12 on the second element 13 is carried out in the direction of descent so that water cannot penetrate between two successive elements 12, 13.

Chaque élément monobloc modulaire 12, 13 est réalisé en un matériau synthétique tel que du chlorure de polyvinyl. Il est également possible de prévoir une réalisation des éléments monoblocs modulaires 12, 13 en un matériau métallique tel que de l'aluminium ou de la tôle galvanisée.Each modular monobloc element 12, 13 is made of a synthetic material such as polyvinyl chloride. It is also possible to provide for an embodiment of the one-piece elements modular 12, 13 made of a metallic material such as aluminum or galvanized sheet.
