Abstract

The invention concerns a method for the installation of a pavement kerb (10) whereof at least one face (12, 14, 16) comprises a reflecting surface consisting at least partially of a layer of juxtaposed transparent spherical balls (18). The method consists in casting a material such as concrete on the site where the kerb is to be installed, in moulding the kerb to give it its final shape, in casting the balls on at least one of the kerb surfaces, and in inlaying the balls in the material on the face designed to be reflecting.

Description

Bordure de chaussée réfléchissante Reflective curb
Domaine TechniqueTechnical area
La présente invention concerne les bordures de chaussée et la façon de les rendre réfléchissantes pour une meilleure visibilité de nuit et en particulier un procédé d'installation en continu d'une bordure de chaussée réfléchissante et les moyens de mise en œuvre.The present invention relates to curbs and how to make them reflective for better visibility at night and in particular a method of continuous installation of a reflective curb and the means of implementation.
Etat de la techniqueState of the art
De façon à améliorer la sécurité routière de nuit on a cherché à rendre les bordures de chaussée visibles la nuit, qu'il s'agisse des bordures de trottoir, des bordures d'ilôts directionnels, des glissières de protection, des séparateurs de voies, des bordures de défense, etc. Une technique consiste à peindre les bordures pour les rendre réfléchissantes. Malheureusement, la peinture réfléchissante doit être refaite régulièrement du fait qu'elle donne lieu à une usure rapide. On a donc songé à utiliser des billes de verre réfléchissantes qui sont incorporées dans tout ou partie de la surface extérieure de la bordure, les billes de verre étant fixées dans la couche superficielle par le durcissement du béton constituant la bordure. De telles bordures sont décrites dans le brevet français FR 1.441.061.In order to improve road safety at night, we have tried to make the curbs visible at night, whether they are sidewalks, curbs of directional islands, protective barriers, lane dividers, defense borders, etc. One technique is to paint the borders to make them reflective. Unfortunately, the reflective paint has to be redone regularly because it gives rise to rapid wear. Consideration has therefore been given to using reflective glass beads which are incorporated into all or part of the outer surface of the border, the glass balls being fixed in the surface layer by the hardening of the concrete constituting the border. Such borders are described in French patent FR 1,441,061.
L'installation des bordures peut être réalisée soit en assemblant des éléments de bordure préfabriqués en usine soit in situ. La pose d'éléments préfabriqués est malheureusement onéreuse, d'exécution lente et occasionne des problèmes lombaires aux ouvriers en charge de la pose.The installation of the borders can be carried out either by assembling prefabricated border elements in the factory or in situ. The installation of prefabricated elements is unfortunately expensive, slow execution and causes lumbar problems to the workers in charge of the installation.
Le procédé d' incrustation des billes de verre dans le béton est également déterminant pour réaliser des bordures de bonne qualité tout en utilisant une pose efficace et rapide. Par exemple le brevet FR 1441.061 décrit un procédé d'incrustation des billes par projection sous une pression relativement importante. Ce procédé est malheureusement inefficace, qu'il soit réalisé in situ ou en usine. En effet, lorsqu'il est réalisé directement sur place, le béton est livré par des camions « toupie » et présente une plasticité variable pour chaque camion qui arrive sur le chantier. En plus, la durée de déchargement et l'avancement des travaux sont aussi des facteurs qui modifient la plasticité du béton. Cette plasticité variable devrait alors être déterminée dans chaque cas de façon à régler la pression utilisée pour la projection des billes. Il en est de même lorsque les éléments de bordure sont fabriqués en usine dans la mesure où la plasticité du béton est différente d'un malaxeur à l'autre et évolue entre la période de coulage, de démoulage et de projection des billes.The process of embedding glass beads in concrete is also crucial for achieving good quality borders while using an efficient and rapid installation. For example, patent FR 1441.061 describes a method of encrusting the balls by spraying under pressure. relatively large. This process is unfortunately ineffective, whether carried out in situ or in the factory. When it is produced directly on site, the concrete is delivered by “mixer” trucks and has a variable plasticity for each truck that arrives at the site. In addition, the duration of unloading and the progress of the work are also factors which modify the plasticity of concrete. This variable plasticity should then be determined in each case so as to regulate the pressure used for the projection of the balls. It is the same when the border elements are manufactured in the factory insofar as the plasticity of the concrete is different from one mixer to another and changes between the period of pouring, demolding and projection of the balls.
Exposé de l'inventionStatement of the invention
Le but de l'invention est donc de mettre en œuvre un procédé d' installation en continu de bordures de chaussée réfléchissantes qui soit rapide, qui puisse s'adapter en permanence à la plasticité du béton utilisé et qui n'occasionne pas de difficultés pour les personnes chargées de la pose des bordures.The object of the invention is therefore to implement a process for the continuous installation of reflective curbs which is rapid, which can constantly adapt to the plasticity of the concrete used and which does not cause difficulties for the people responsible for installing the borders.
Par conséquent, l'objet de l'invention est un procédé d'installation en continu d'une bordure de chaussée à surface réfléchissante constituée de billes de verres, consistant à couler le matériau devant constituer la bordure à l'emplacement où doit être posée celle-ci, à mouler la bordure pour lui donner sa forme définitive, à couler les billes sur au moins une des faces de la bordure, et à incruster ces billes dans le matériau de la bordure par application d'une pression qui est fonction de la plasticité du matériau constituant la bordure.Consequently, the object of the invention is a process for the continuous installation of a curb of a roadway with a reflective surface made up of glass beads, consisting in pouring the material which must constitute the curb at the location where it is to be laid. the latter, molding the border to give it its final shape, pouring the balls on at least one of the faces of the border, and embedding these balls in the material of the border by application of a pressure which is a function of the plasticity of the material constituting the border.
Un autre objet de l'invention est une machine de mise en œuvre en continu du procédé ci-dessus. Description brève des figuresAnother object of the invention is a machine for continuously implementing the above method. Brief description of the figures
Les buts, objets et caractéristiques de l'invention apparaîtront plus clairement à la lecture de la description suivante en référence aux dessins dans lesquels : la figure 1 représente un élément de bordure de chaussée selon la présente invention, la figure 2 représente une coupe transversale de l'élément de bordure illustré sur la figure 1, la figure 3 est une représentation schématique de la machine mettant en œuvre le procédé de pose en continu de la bordure de chaussée selon l'invention, et la figure 4 est une vue en coupe de la bordure de chaussée et du moyen d'incrustation des billes dans les faces de la bordure de chaussée.The objects, objects and characteristics of the invention will appear more clearly on reading the following description with reference to the drawings in which: FIG. 1 represents a road edge element according to the present invention, FIG. 2 represents a cross section of the border element illustrated in FIG. 1, FIG. 3 is a diagrammatic representation of the machine implementing the method for continuously laying the curb according to the invention, and FIG. 4 is a sectional view of the edge of the roadway and the means for encrusting the balls in the faces of the roadway edge.
Description détaillée de l'inventionDetailed description of the invention
Comme illustré sur la figure 1, une bordure de chaussée 10 fabriquée par le procédé selon l'invention comporte sur la face verticale 12, la face inclinée 14 et la face horizontale 16, des billes spheriques 18 incrustées dans le matériau 20 constituant la bordure 10, généralement du béton. On doit noter que, bien les billes sont incrustées de préférence, elles pourraient être fixées à la surface des faces réfléchissantes de la bordure par tout autre moyen sans sortir du cadre de l'invention.As illustrated in FIG. 1, a road edge 10 produced by the method according to the invention comprises on the vertical face 12, the inclined face 14 and the horizontal face 16, spherical balls 18 embedded in the material 20 constituting the edge 10 , usually concrete. It should be noted that, although the balls are preferably encrusted, they could be fixed to the surface of the reflective faces of the border by any other means without departing from the scope of the invention.
Comme le montre la figure 2, les billes spheriques 18 sont de préférence juxtaposées de façon à recouvrir le maximum de surface du béton 20. Les billes 18 sont de préférence des billes de verre transparentes mais pouvant être en tout autre matière transparente telle que de la matière plastique. Elle sont microscopiques, d'un diamètre généralement compris entre 100 microns et 2 mm. Du fait de la réfraction de la lumière par les billes ainsi que la réflexion de la lumière due à l'interface entre les billes et le béton, la lumière de l'éclairage public ou des phares de voiture est réfléchie et procure une visibilité efficace des bordures de chaussée la nuit.As shown in FIG. 2, the spherical balls 18 are preferably juxtaposed so as to cover the maximum surface area of the concrete 20. The balls 18 are preferably transparent glass balls but may be made of any other transparent material such as plastic material. They are microscopic, with a diameter generally between 100 microns and 2 mm. Due to the refraction of the light by the balls as well as the reflection of the light due to the interface between the balls and the concrete, the light of public lighting or headlights of car is thoughtful and provides effective visibility of curbs at night.
On doit noter qu'il n'est pas impératif que toutes les faces de la bordure de chaussée comportent des surfaces réfléchissantes ou que la totalité de chaque surface soit réfléchissante comme c'est le cas dans les figures 1 et 2. On peut se contenter d'une seule surface réfléchissante qui peut être soit la surface verticale 12, soit la surface inclinée 14 (s'il en existe une), soit la surface horizontale 16, soit deux d'entre elles, soit des parties seulement de ces surfaces .It should be noted that it is not imperative that all the faces of the curb have reflective surfaces or that the totality of each surface is reflective as is the case in FIGS. 1 and 2. We can be satisfied of a single reflecting surface which can be either the vertical surface 12, or the inclined surface 14 (if there is one), or the horizontal surface 16, or two of them, or only parts of these surfaces.
Par contre il est également possible de recouvrir toutes les faces de la bordure y compris la face arrière dans le cas d'une bordure isolée du type îlot ou des bordures de piste cyclable.On the other hand, it is also possible to cover all the faces of the curb including the rear face in the case of an isolated curb of the island type or of the curbs of a cycle track.
Le procédé d'installation en continu de la bordure selon l'invention s'exécute au moyen de la machine représentée schématiquement sur la figure 3.The process of continuous installation of the border according to the invention is carried out by means of the machine shown diagrammatically in FIG. 3.
Cette machine avance de gauche à droite et permet la pose en continu de la bordure de chaussée. En tête se trouve une trémie 30 d'arrivée du béton 32. Le béton est ensuite compacté au moyen d'une vis sans fin 34, ce qui permet de donner une bonne homogénéité au béton. Puis la bordure est moulée dans sa forme définitive par le moule à coffrage glissant 36. Ensuite, une petite trémie 38 permet l'arrivée des microbilles 40 sur les faces de la bordure où les microbilles doivent être incrustées. L'arrière de la trémie est prolongé par des ensembles de deux pièces métalliques, une première pièce 42 parallèle à la bordure et une deuxième pièce 44 formée de plan inclinés par rapport à la surface de la bordure où vont être incrustées les microbilles. L'inclinaison de la deuxième pièce 44 est déterminée par une vis (ou plusieurs) 46 prenant appui sur la première pièce fixe 42. La pression exercée par la pièce inclinée 44 sur les billes se trouvant à la surface du béton moulé provoque leur incrustation dans le béton.This machine moves from left to right and allows continuous laying of the curb. At the head is a concrete inlet hopper 30. The concrete is then compacted by means of an endless screw 34, which makes it possible to give good homogeneity to the concrete. Then the border is molded in its final form by the sliding formwork mold 36. Next, a small hopper 38 allows the arrival of the microbeads 40 on the faces of the border where the microbeads must be embedded. The rear of the hopper is extended by sets of two metal parts, a first part 42 parallel to the border and a second part 44 formed of planes inclined relative to the surface of the border where the microbeads will be embedded. The inclination of the second part 44 is determined by a screw (or more) 46 bearing on the first fixed part 42. The pressure exerted by the inclined part 44 on the balls on the surface of the molded concrete cause their encrustation in the concrete.
La vis 46 permet le réglage de la pression exercée sur les billes et l'angle d'inclinaison des éléments de la deuxième pièce 44 par rapport à la première pièce 42. Ce réglage est fonction de la consistance et de la plasticité du béton. Si le degré d'humidité du béton est élevé (béton humide) la pression devra être faible. Inversement, avec un degré d'humidité peu élevé (béton sec), la pression nécessaire devra être plus importante. En fonction de ce réglage, l'angle d'inclinaison variera entre 2 et 10 ° .The screw 46 allows the adjustment of the pressure exerted on the balls and the angle of inclination of the elements of the second part 44 relative to the first part 42. This adjustment is a function of the consistency and the plasticity of the concrete. If the humidity of the concrete is high (wet concrete) the pressure should be low. Conversely, with a low humidity level (dry concrete), the necessary pressure will have to be greater. Depending on this setting, the tilt angle will vary between 2 and 10 °.
Le nombre d'éléments de la deuxième pièce 44 varie en fonction du nombre de faces sur lesquelles on procède à l'incrustation de billes. Ainsi, dans le cas illustré sur la figure 1, trois faces de la bordure donnent lieu à incrustation, et il faut donc prévoir trois éléments inclinés pour la deuxième pièce 44 ainsi qu'une première pièce 42 ayant une forme correspondant à celle de la bordure mais un peu plus grande en hauteur et en largeur, les deux pièces étant solidaires à l'avant et rendues solidaires par une ou plusieurs vis 46 à l'arrière.The number of elements of the second part 44 varies depending on the number of faces on which the beads are incrusted. Thus, in the case illustrated in FIG. 1, three faces of the border give rise to inlaying, and it is therefore necessary to provide three inclined elements for the second part 44 as well as a first part 42 having a shape corresponding to that of the border. but a little larger in height and width, the two parts being integral at the front and made integral by one or more screws 46 at the rear.
En pratique, une machine selon l'invention a un poids d'environ 350 kg. Elle dispose de vérins permettant un réglage en hauteur et une correction précise du dévers. Elle permet la réalisation de tous types de bordures d'une dimension maximale de 50cm de haut et 60cm de large, et donc de toutes les bordures normalisées (plus de 50 références de moules) . Cette machine permet ainsi de réaliser des bourrelets en béton bitumineux, des bordures colorées, désactivées ou à gorge. La possibilité d' interchanger le côté extrusion, à droite ou à gauche, permet de se raccorder à des ouvrages existants. A noter que c'est le compactage du béton au moyen de la vis sans fin qui permet le déplacement de la machine à une vitesse comprise entre 1 et 6m par minute. Le procédé de réalisation de bordure de chaussée réfléchissante qui vient d'être décrite n'implique pas déporter des charges lourdes pour les ouvriers, permet une exécution rapide ainsi qu'une grande mobilité et s'adapte en permanence à la plasticité du béton. Son coût est très nettement inférieur à celui des bordures préfabriquées et s'applique à tous les types de bordures. Elle améliore très sensiblement la sécurité routière de nuit recherchée en permanence par les Directions Départementales de l'Equipement, les Conseils Généraux et les Collectivités Locales . In practice, a machine according to the invention has a weight of approximately 350 kg. It has cylinders allowing height adjustment and precise correction of the slope. It allows the production of all types of borders with a maximum dimension of 50cm high and 60cm wide, and therefore of all standardized borders (more than 50 mold references). This machine thus makes it possible to produce bituminous concrete beads, colored borders, deactivated or grooved. The possibility of interchanging the extrusion side, to the right or to the left, allows connection to existing structures. Note that it is the compaction of the concrete by means of the worm which allows the machine to move at a speed between 1 and 6m per minute. The process for producing a reflective curb which has just been described does not involve carrying heavy loads for workers, allows rapid execution as well as great mobility and constantly adapts to the plasticity of the concrete. Its cost is very much lower than that of prefabricated borders and applies to all types of borders. It very significantly improves night-time road safety, which is constantly sought by the Departmental Equipment Directorates, General Councils and Local Authorities.
