Description

L'objet de l'invention concerne le domaine technique des dispositifs appelés habituellement ralentisseurs et aménagés sur une chaussée de circulation afin de ralentir les véhicules y circulant.The object of the invention relates to the technical field of devices usually called speed bumps and arranged on a roadway to slow down the vehicles circulating there.

Il est connu dans l'état de la technique de nombreuses formes de réalisation de ralentisseurs. Ainsi, il est connu de réaliser transversalement par rapport au sens de circulation, un obstacle se présentant sous la forme d'un plateau surélevé raccordé à la chaussée de circulation par des rampants amont et aval. Ce type de ralentisseurs est réalisé in situ à partir de divers matériaux associant, notamment, des pavés et de l'enrobé conformé pour constituer un obstacle.Many embodiments of retarders are known in the state of the art. Thus, it is known to achieve transversely with respect to the direction of movement, an obstacle in the form of a raised plateau connected to the roadway by crawling upstream and downstream. This type of retarder is made in situ from various materials including cobblestones and asphalt shaped to constitute an obstacle.

Ainsi, le document FR 2 590 602 , décrit un ralentisseur de circulation du type dos d'âne constitué à partir de dalles clavetées entre elles. Les dalles sont calées à chacune des extrémités du ralentisseur, par une bordure transversale formée de tronçons en béton préfabriqués.Thus, the document FR 2 590 602 , describes a humpback type speed reducer made from slabs wedged between them. The slabs are wedged at each end of the retarder, by a transverse edge formed of prefabricated concrete sections.

Les ralentisseurs connus présentent un inconvénient majeur, notamment, pour les transports en commun dans la mesure où le franchissement de tels obstacles nuit au confort des passagers. De plus, les ralentisseurs constituent des obstacles s'étendant transversalement à la chaussée, ce qui constitue un réel danger pour les véhicules à deux roues. Par ailleurs, l'aménagement des ralentisseurs in situ constitue un ouvrage relativement long et délicat à mener à bien, imposant de fermer la chaussée à la circulation. Enfin, il est à considérer que le passage des véhicules sur un ralentisseur constitué à partir de dalles est à même de conduire à des déplacements relatifs entre les dalles, ce qui nécessite une opération de réparation.Known retarders have a major disadvantage, especially for public transport to the extent that the crossing of such obstacles harms the comfort of passengers. In addition, the retarders are obstacles extending transversely to the road, which is a real danger for two-wheeled vehicles. In addition, the development of in situ speed bumps is a relatively long and delicate work to carry out, requiring to close the road to traffic. Finally, it should be considered that the passage of vehicles on a slab-based retarder is able to lead to relative movements between the slabs, which requires a repair operation.

Pour remédier aux inconvénients énoncés ci-dessus, le brevet FR 2 772 401 a proposé un dispositif de ralentissement constitué sous la forme d'un bloc présentant un plateau supérieur possédant une largeur d'une part, supérieure à l'empattement ou à la largeur de voie d'un premier type de véhicules tels que des véhicules de tourisme et d'autre part, inférieure à l'empattement ou à la largeur de voie d'un deuxième type de véhicules tels que camions ou transports en commun. Ce plateau supérieur présente une hauteur par rapport au plan d'extension inférieure à la garde au sol des véhicules de deuxième type. Ce bloc ralentisseur est équipé également de deux rampants latéraux s'étendant de part et d'autre du plateau supérieur et à partir de ce dernier jusqu'au plan d'extension.To overcome the disadvantages set out above, the Patent FR 2 772 401a proposed a slowing device constituted in the form of a block having an upper plate having a width on the one hand, greater than the wheelbase or the track width of a first type of vehicles such as passenger vehicles and on the other hand, lower than the wheelbase or track width of a second type of vehicle such as trucks or public transport. This upper plate has a height relative to the plane of extension less than the ground clearance of second type vehicles. This retarder block is also equipped with two lateral crawlers extending from both sides of the upper plate and from the latter to the extension plane.

Un tel dispositif ralentisseur donne entière satisfaction. Cependant, il a été constaté dans des conditions particulières d'utilisation et/ou dans des conditions anormales d'implantation, l'apparition de fissures à la surface du bloc ralentisseur, ce qui, à terme, risque d'altérer son intégrité.Such a retarder device gives complete satisfaction. However, it has been found under particular conditions of use and / or in abnormal implantation conditions, the appearance of cracks on the surface of the retarder block, which, in the long term, may alter its integrity.

La présente invention vise donc à proposer un dispositif ralentisseur durable dans le temps, quelles que soient ses conditions d'installation et d'utilisation, conçu pour assurer une fonction de ralentissement des véhicules en maintenant un confort des passagers pour les véhicules de transport en commun, tout en étant adapté pour être mis en place relativement facilement et rapidement sur une chaussée de circulation.The present invention therefore aims to provide a durable retarder device over time, regardless of its conditions of installation and use, designed to provide a vehicle slowdown function while maintaining passenger comfort for public transport vehicles , while being adapted to be put in place relatively easily and quickly on a traffic pavement.

Par exemple, le talon d'appui présente par rapport à la face inférieure une hauteur comprise entre 3 et 10 cm et de préférence, sensiblement égale à 5 cm.For example, the support heel has with respect to the lower face a height of between 3 and 10 cm and preferably substantially equal to 5 cm.

Avantageusement, le bloc ralentisseur comporte deux rampants latéraux s'étendant de part et d'autre du plateau supérieur et à partir de ce dernier jusqu'au plan d'extension, chaque rampant latéral étant raccordé à un rampant amont ou aval selon une arête bissectrice.Advantageously, the retarder block comprises two lateral crawlers extending on either side of the upper plate and from the latter to the extension plane, each lateral crawler being connected to an upstream or downstream crawler along a bisecting edge. .

Diverses autres caractéristiques ressortent de la description faite ci-dessous en référence aux dessins annexés qui montrent, à titre d'exemples non limitatifs, des formes de réalisation de l'objet de l'invention.Various other characteristics appear from the description given below with reference to the accompanying drawings which show, by way of non-limiting examples, embodiments of the subject of the invention.

La Fig. 1 est une vue de dessus d'un dispositif ralentisseur conforme à l'invention.The Fig. 1 is a top view of a retarder device according to the invention.

La Fig. 2 est une vue en coupe longitudinale prise sensiblement selon les lignes II-II de la Fig. 1 . The Fig. 2 is a view in longitudinal section taken substantially along the lines II-II of the Fig. 1 .

Tel que cela ressort des Fig. 1 et 2 , l'objet de l'invention concerne un dispositif 1 conçu pour ralentir des véhicules roulant sur une chaussée 2 de circulation au sens général. Selon une caractéristique de l'invention, le dispositif ralentisseur 1 est constitué sous la forme d'au moins un bloc compact ou unitaire réalisé avantageusement en béton armé.As is apparent from Fig. 1 and 2 The object of the invention relates to a device 1 designed to slow down vehicles traveling on a roadway 2 of traffic in the general sense. According to one characteristic of the invention, the retarder device 1 is constituted in the form of at least one compact or unit block advantageously made of reinforced concrete.

Le bloc ralentisseur 1 présente un plateau supérieur 3 s'étendant dans un plan P saillant par rapport à un plan d'extension E destiné à s'établir au niveau de la chaussée de circulation 2. Selon une caractéristique avantageuse de l'invention, la hauteur H prise entre le plan saillant P et le plan d'extension E, présente une valeur sensiblement égale à 7 cm.The retarder block 1 has an upper plate 3 extending in a plane P salient with respect to an extension plane E intended to be established at the level of the traffic pavement 2 . According to an advantageous characteristic of the invention, the height H taken between the projecting plane P and the extension plane E has a value substantially equal to 7 cm.

Le bloc ralentisseur 1 comporte, par rapport au sens de circulation des véhicules, par exemple représenté par la flèche f, un rampant amont 5 et un rampant aval 6 s'étendant entre le plan saillant P et le plan d'extension E. Les rampants amont 5 et aval 6 se trouvent ainsi délimités entre le plateau supérieur 3 et respectivement des bords d'attaque 51 et de fuite 61 . Chaque rampant amont 5 et aval 6 possèdent une longueur L1 comprise entre 40 et 50 cm et, de préférence, de l'ordre de 45 cm. Avantageusement, la longueur L2 du bloc ralentisseur 1, incluant celles du plateau 3 et des rampants amont et aval, est comprise entre 250 et 350 cm et, de préférence, de l'ordre de 300 cm.The retarder block 1 comprises, with respect to the direction of circulation of the vehicles, for example represented by the arrow f, an upstream ramp 5 and a downstream ramp 6 extending between the projecting plane P and the extension plane E. The upstream and downstream crawling 5 6 are thus defined between the upper plate 3 and the edges respectively of attack of 5 1 and 6 1 of leakage. Each creeper upstream 5 and downstream 6 have a length L 1 of between 40 and 50 cm and preferably of the order of 45 cm.

Selon une autre caractéristique avantageuse de l'invention, le plateau supérieur 3 possède dans un sens perpendiculaire au sens de circulation f, une largeur l1 , d'une part, supérieure à la largeur de voie d'un premier type de véhicules et, d'autre part, inférieure à la largeur de voie d'un second type de véhicules. Le plateau 3 possède ainsi une largeur inférieure à la largeur de voie des véhicules du type camions ou transports en commun, tels que des bus, et supérieure à la largeur de voie des véhicules de tourisme. Ainsi, le plateau supérieur 3 possède une largeur l 1 comprise entre 110 et 120 cm et, de préférence, de l'ordre de 115 cm. Par ailleurs, la hauteur H du plateau supérieur 3 est inférieure à la garde au sol des véhicules du second type, à savoir camions ou transports en commun.According to another advantageous characteristic of the invention, the upper plate 3 has in a direction perpendicular to the direction of circulation f , a width l 1 , on the one hand, greater than the track width of a first type of vehicle and, on the other hand, less than the track width of a second type of vehicle. The plate 3 thus has a width less than the track width of vehicles of the truck or public transport type, such as buses, and greater than the track width of passenger vehicles. Thus, the upper plate 3 has a width l 1 of between 110 and 120 cm and preferably of the order of 115 cm. Moreover, the height H of the upper plate 3 is less than the ground clearance of vehicles of the second type, namely trucks or public transport.

Chaque rampant latéral 8 possède une largeur l2 comprise entre 30 et 40 cm et, de préférence, de l'ordre de 35 cm. Les rampants latéraux 8 sont raccordés aux rampants amont 5 et aval 6 selon des arêtes bissectrices 9, de sorte que chaque rampant présente, en vue de dessus, une forme trapézoïdale.According to another characteristic of the invention, the retarder block 1 according to the invention comprises two lateral rampants 8 extending on either side of the upper plate 3 , and from the latter to the extension plane E . Each lateral crawler 8 has a width l 2 of between 30 and 40 cm and preferably of the order of 35 cm. The lateral crawlers 8 are connected to the upstream crawlers 5 and downstream 6 along bisecting edges 9 , so that each crawler has, in top view, a trapezoidal shape.

Avantageusement, le bloc ralentisseur 1 comporte une semelle ou une embase 11 possédant avantageusement une forme parallélépipédique entre le plan d'extension E et sa face inférieure 111 . L'embase 11 présente une hauteur H1 adaptée pour être enterrée ou enchâssée dans la voie de circulation 2. La hauteur H1 de la semelle prise entre la face inférieure 111 et le plan d'extension E c'est-à-dire au niveau de l'arête de jonction entre les rampants et les bords de la semelle 11, est comprise entre 5 et 15 cm et de préférence, sensiblement égale 10 cm.Advantageously, the retarder block 1 comprises a sole or a base 11 advantageously having a parallelepipedal shape between the extension plane E and its lower face 11 1 . The base 11 has a height H 1 adapted to be buried or encased in the traffic lane 2 . The height H 1 of the soleplate taken between the lower face 11 1 and the extension plane E that is to say at the junction edge between the crawlers and the edges of the sole 11 is between 5 and 15 cm and preferably substantially equal to 10 cm.

Selon une autre caractéristique de l'invention, le bloc ralentisseur 1 est équipé de moyens 13 assurant sa manutention. Par exemple, les moyens 13 sont constitués par l'intermédiaire de douilles de manutention réalisées par exemple en inox et mises en place au moment du coulage du béton. Ces douilles présentent ou permettent la mise en place d'un anneau pour la mise en place d'élingues de manutention. Dans l'exemple illustré, les moyens de manutention 13 sont constitués par des douilles situées aux quatre coins du plateau supérieur 3.According to another characteristic of the invention, the retarder block 1 is equipped with means 13 ensuring its handling. For example, the means 13 are formed by means of handling sleeves made for example of stainless steel and put in place at the time of pouring the concrete. These sleeves present or allow the establishment of a ring for the introduction of handling slings. In the illustrated example, the handling means 13 consist of sockets located at the four corners of the upper plate 3 .

Le bloc ralentisseur 1 constitue avantageusement un élément monobloc réalisé par moulage. Toutefois, il est à noter que le bloc ralentisseur peut être réalisé en une ou plusieurs parties montées les unes à côté des autres pour certaines applications spécifiques. D'une manière classique, le bloc ralentisseur 1 est destiné à être placé par tous moyens de manutention appropriés sur un lit de réception 14 aménagé dans la chaussée 2 selon les règles classiques de construction routière. Un enrobé 15 est ensuite réalisé autour du bloc 1 pour venir s'étendre jusqu'au niveau du plan d'extension E, c'est-à-dire jusqu'à la base des rampants ou encore l'arête de jonction entre les rampants et les bords de la semelle 11. La semelle 11 se trouve ainsi enterrée, de sorte que s'étendent en saillie au-dessus du niveau de la chaussée de circulation, les rampants aval, amont et latéraux, ainsi que le plateau supérieur 3. La durée des travaux pour la mise en place d'un tel dispositif ralentisseur peut être réduite à une journée.The retarder block 1 advantageously constitutes a one-piece element produced by molding. However, it should be noted that the retarder block can be made in one or more parts mounted next to each other for certain specific applications. In a conventional manner, the retarder block 1 is intended to be placed by any appropriate handling means on a receiving bed 14 arranged in the roadway 2 according to the conventional rules of road construction. A mix 15 is then made around the block 1 to extend to the level of the extension plane E , that is to say to the base of the crawling or the junction edge between the crawling and the edges of the sole 11 . The sole 11 is thus buried, so that protrude above the level of the traffic pavement, the downstream, upstream and lateral rampants, as well as the upper plate 3 . The duration of the work for the implementation of such a device retarder can be reduced to one day.

Le bloc ralentisseur 1 est ainsi implanté parallèlement au sens f de la circulation, en constituant un obstacle pour les véhicules de tourisme par l'intermédiaire du plateau supérieur 3, dont la largeur l1 est supérieure à la largeur de voie de ce type de véhicules. Cependant, le bloc ralentisseur ne constitue pas un obstacle pour les transports en commun qui ne roulent pas sur le plateau supérieur 3, compte tenu de leur largeur de voie supérieure à la largeur l 1 du plateau 3. Les véhicules de transport en commun peuvent ainsi rouler sur les rampants latéraux 8, plutôt vers leurs bords longitudinaux extérieurs, sans risque de toucher le plateau supérieur 3, compte tenu de la garde au sol de tels véhicules qui est supérieure à la hauteur H du bloc ralentisseur. De plus, les véhicules à deux roues peuvent rouler sur les rampants latéraux, plutôt vers leurs bords longitudinaux extérieurs, de sorte qu'un tel bloc ne constitue pas un réel obstacle ou danger pour ce type de véhicules.The retarder block 1 is thus implanted parallel to the direction f of the traffic, constituting an obstacle for passenger vehicles via the upper plate 3 , whose width l 1 is greater than the track width of this type of vehicle . However, the retarder block does not constitute an obstacle for public transport that does not roll on the upper plate 3 , given their track width greater than the width l 1 of the plate 3 . The public transport vehicles can thus roll on the lateral ramps 8 , rather to their outer longitudinal edges, without risk of touching the upper plate 3 , given the ground clearance of such vehicles which is greater than the height H of the block retarder. In addition, two-wheeled vehicles can roll on the side rails, rather to their outer longitudinal edges, so that such a block does not constitute a real obstacle or danger for this type of vehicle.

Conformément à l'invention, le bloc ralentisseur 1 comporte au moins un talon d'appui 20 s'étendant en saillie à partir de la face inférieure 111 de la semelle et du bord d'attaque 51 sur une longueur L3 limitée prise en considération du sens de circulation f. Par exemple, le talon d'appui 20 s'étend sur une longueur L3 comprise entre 15 et 35 cm et de préférence, sensiblement égale à 25 cm.According to the invention, the retarder block 1 comprises at least one support heel 20 projecting from the lower face 11 1 of the sole and the leading edge 5 1 on a length L 3 limited taken in consideration of the direction of traffic f . For example, the bearing heel 20 extends over a length L 3 of between 15 and 35 cm and preferably substantially equal to 25 cm.

De manière préférée, le talon d'appui 20 est raccordé à la face inférieure 111 , du côté opposé du bord d'attaque 51 , par un chanfrein de raccordement 21. Par exemple, le chanfrein de raccordement 21 s'étend sur une longueur L4 prise en considération du sens de circulation f sensiblement égale à 5 cm. Avantageusement, le talon d'appui 20 présente par rapport à la face inférieure 111 de la semelle 11, une hauteur H2 comprise entre 3 et 10 cm et de préférence, sensiblement égale à 5 cm.Preferably, the bearing heel 20 is connected to the lower face 11 1 , on the opposite side of the leading edge 5 1 , by a connecting chamfer 21. For example, the connecting chamfer 21 extends over a length L 4 taken into consideration the direction of movement f substantially equal to 5 cm. Advantageously, the bearing heel 20 has with respect to the lower face 11 1 of the sole 11 , a height H 2 of between 3 and 10 cm and preferably substantially equal to 5 cm.

La mise en oeuvre d'un talon d'appui 20 au niveau du rampant amont 5 permet de renforcer le bloc ralentisseur tout en limitant le poids d'un tel bloc. De plus, le talon d'appui favorise l'ancrage du bloc ralentisseur dans la chaussée 2. Dans l'exemple considéré, le talon d'appui 20 s'étend sur une longueur limitée à partir du bord d'attaque 51 et jusqu'aux côtés latéraux de la semelle 11. Selon une autre variante de réalisation, il peut être prévu de réaliser de manière symétrique à partir du bord de fuite 61 un talon d'appui identique au talon d'appui 20. Selon cette variante, un tel talon d'appui s'étend en saillie à partir de la face inférieure 111 et du bord de fuite 61 sur une longueur limitée prise en considération du sens de circulation f, comprise entre 15 et 35 cm et de préférence, sensiblement égale à 25 cm. Un tel talon d'appui peut être raccordé à la face inférieure par un chanfrein de raccordement identique au chanfrein de raccordement 21. Cette variante de réalisation permet de réaliser un bloc ralentisseur symétrique par rapport au plan transversal médian. Un tel bloc ralentisseur peut être avantageusement utilisé sur une voie unique à double sens de sorte que le bord de fuite 61 constitue aussi un bord d'attaque en considération du sens de circulation des véhicules.The implementation of a bearing heel 20 at the level of the upstream ramp 5 reinforces the retarder block while limiting the weight of such a block. In addition, the support heel promotes the anchoring of the retarder block in the roadway 2 . In the example considered, the support heel 20 extends over a limited length from the leading edge 5 1 and to the lateral sides of the sole 11 . According to another variant embodiment, it can be provided to achieve symmetrically from the trailing edge 6 1 a support heel identical to the support heel 20 . According to this variant, such a support heel protrudes from the lower face 11 1 and the trailing edge 6 1 over a limited length taken into consideration the direction of movement f , between 15 and 35 cm and preferably, substantially equal to 25 cm. Such a support heel can be connected to the lower face by a connecting chamfer identical to the connecting chamfer 21 . This variant embodiment makes it possible to produce a symmetrical retarder block with respect to the median transverse plane. Such a retarder block can be advantageously used on a single two-way lane so that the trailing edge 6 1 also constitutes a leading edge in consideration of the direction of traffic of the vehicles.

L'invention n'est pas limitée aux exemples décrits et représentés car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the examples described and shown because various modifications can be made without departing from its scope.
