Description

L'invention concerne un dispositif ralentisseur routier, en particulier du type coussin berlinois. Un coussin berlinois est un dispositif ralentisseur de sécurité routière surélevant la chaussée selon une largeur appropriée de la route. Sa largeur par rapport à la route est adaptée pour être supérieure à l'entraxe des roues d'une voiture afin que la voiture roule nécessairement dessus, et inférieure à l'entraxe des roues d'un autocar de sorte que celui-ci puisse passer au-dessus, tandis que les véhicules à deux roues (bicyclettes, motos) peuvent poursuivre leur trajectoire sur la chaussée en passant sur le côté du coussin.The invention relates to a road retarder device, in particular of the speed bump type. A speed bump is a road safety device that raises the road surface to an appropriate width of the road. Its width relative to the road is adapted to be greater than the center distance of the wheels of a car so that the car necessarily rolls over it, and less than the center distance of the wheels of a coach so that the latter can pass above, while two-wheeled vehicles (bicycles, motorcycles) can continue their trajectory on the roadway by passing on the side of the cushion.

Il est connu différents types de ralentisseurs routiers décrits par exemple par le document GB-A-2030197 décrivant un agencement d'obstacle routier ralentisseur, le document FR-A-2590602 décrivant un ralentisseur de circulation de type dos d'âne et le document US-A-5267367 décrivant un dispositif comportant des rampes pour protéger un conduit contre les dommages causés par le passage du trafic sur ces conduits.It is known different types of road retarders described for example by the document GB-A-2030197 describing a speed bump road obstacle arrangement, the document FR-A-2590602 describing a speed bump type traffic speed bump and the document US-A-5267367 describing a device comprising ramps to protect a duct against damage caused by the passage of traffic on these ducts.

Un coussin berlinois est soit en béton, soit en matière plastique à base de caoutchouc.A speed bump is either made of concrete or rubber-based plastic.

En béton, il s'agit d'un dispositif monolithique. Cependant, un tel dispositif a tendance avec le temps à se fissurer, et même à casser en de multiples endroits, car il ne résiste pas aux efforts de flexion induits par le passage répété de véhicules lourds.Made of concrete, it is a monolithic device. However, such a device tends over time to crack, and even to break in multiple places, because it does not withstand the bending forces induced by the repeated passage of heavy vehicles.

En matière plastique, le dispositif comporte une pluralité de modules aboutés latéralement les uns aux autres et solidarisés à la chaussée selon leur hauteur par des moyens de fixation du type tire-fond. Néanmoins, ce dispositif présente également des inconvénients ; les modules ont tendance à se désolidariser dans le temps en s'écartant les uns des autres, et à présenter leur texture de surface antidérapante devenir glissante par l'usure.Made of plastic material, the device comprises a plurality of modules butted laterally to each other and secured to the roadway according to their height by lag-screw type fastening means. However, this device also has drawbacks; the modules tend to separate over time by moving apart from each other, and to have their non-slip surface texture become slippery with wear.

L'invention a donc pour but de proposer un dispositif ralentisseur du type coussin berlinois qui obvie aux inconvénients précités en procurant un dispositif pérenne dans le temps, tout étant aisé et rapide à installer.The object of the invention is therefore to provide a retarder device of the speed bump type which obviates the aforementioned drawbacks by providing a device that lasts over time, while being easy and quick to install.

Selon l'invention, le dispositif ralentisseur routier, du type coussin berlinois, est en béton et comporte au moins deux modules en béton qui sont assemblés latéralement l'un à l'autre par des formes de coopération mutuelle agencées sur au moins une paroi verticale de chacun des modules. Le dispositif routier ralentisseur est remarquable en ce que au moins un module comporte au moins une paroi verticale dotée d'une alternance de formes mâles qui sont destinées à coopérer par emboîtement avec des formes femelles d'une face latérale d'un module adjacent, les formes mâles et femelles constituant les formes de coopération mutuelle ; en ce que les formes de coopération mutuelle sont une alternance de formes mâles et femelles , de préférence sous la forme de créneaux droits, s'étendant en hauteur depuis l'arête inférieure d'un module, et à distance de l'arête supérieure opposée ; en ce que les formes de coopération mutuelle comportent des formes en queue d'aronde rentrant ou faisant saillie transversalement à un paroi verticale d'un module, la forme en queue d'aronde s'étend sur toute la hauteur du module Les formes de coopération mutuelle sont disposées sur chaque paroi verticale d'un module à associer à un paroi verticale d'un module adjacent. Les formes de coopération mutuelle des modules constituent des moyens de blocage mécanique des modules dans un plan horizontal, lorsque les modules sont associés entre eux. Ainsi, le dispositif est en béton, évitant le risque d'usure que subissent les dispositifs en matière plastique de l'art antérieur. En outre, la pluralité de modules conduit à un dispositif qui n'est pas monolithique et garantit une résistance accrue à la flexion, limitant grandement, voire éliminant, le risque de fissure et de casse.According to the invention, the speed bump device, of the speed bump type, is made of concrete and comprises at least two concrete modules which are joined laterally to each other by forms of mutual cooperation arranged on at least one vertical wall of each of the modules. The road retarder device is remarkable in that at least one module comprises at least one vertical wall provided with an alternation of male shapes which are intended to cooperate by interlocking with female shapes of a side face of an adjacent module, the male and female forms constituting the forms of mutual cooperation; in that the forms of mutual cooperation are an alternation of male and female forms, preferably in the form of straight slots, extending in height from the lower edge of a module, and at a distance from the opposite upper edge ; in that the forms of mutual cooperation comprise dovetail forms entering or projecting transversely to a vertical wall of a module, the dovetail form extends over the entire height of the module The forms of cooperation mutual are arranged on each vertical wall of a module to be associated with a vertical wall of an adjacent module. The forms of mutual cooperation of the modules constitute means of mechanical blocking of the modules in a horizontal plane, when the modules are associated with each other. Thus, the device is made of concrete, avoiding the risk of wear suffered by plastic devices of the prior art. Furthermore, the plurality of modules leads to a device which is not monolithic and guarantees increased resistance to bending, greatly limiting, if not eliminating, the risk of cracking and breakage.

On entend par « latéral » ou « latéralement » dans la suite de la description le qualificatif d'un élément agencé dans un plan vertical en position posée d'un module sur le sol.The term “lateral” or “laterally” in the remainder of the description refers to the qualifier of an element arranged in a vertical plane in the raised position of a module on the ground.

Dans la suite de la description les qualificatifs opposés « supérieur » et « inférieur » d'un élément du dispositif sont utilisés dans le cadre d'une installation normale du dispositif, c'est-à-dire relatif à une notion verticale par rapport à un sol horizontal sur lequel est posé le dispositif, « inférieur » s'entendant donc tourné vers le sol.In the rest of the description, the opposite qualifiers "upper" and "lower" of an element of the device are used in the context of a normal installation of the device, that is to say relating to a vertical concept with respect to a horizontal ground on which the device is placed, “lower” therefore meaning facing the ground.

Selon une caractéristique, un module est assemblé à un autre module en étant imbriqué dans ce dernier lors de la pose du dispositif dans sa destination finale.According to one characteristic, a module is assembled to another module by being nested in the latter during the installation of the device in its final destination.

Avantageusement, l'assemblage de deux modules se fait par emboîtement à la verticale d'un module dans un autre.Advantageously, the assembly of two modules is done by nesting vertically one module in another.

Selon une autre caractéristique, chaque module (de forme polyédrique) comporte au moins une paroi verticale (face latérale) dotée d'une alternance de formes mâles qui sont destinées à coopérer par emboîtement avec des formes femelles d'une paroi verticale (face latérale) d'un module adjacent, les formes mâles et femelles constituant les formes de coopération mutuelle des modules. Les formes femelles sont de préférence réalisées par l'alternance de formes mâles.According to another characteristic, each module (of polyhedral shape) comprises at least one vertical wall (side face) provided with an alternation of male shapes which are intended to cooperate by interlocking with female shapes of a vertical wall (side face) of an adjacent module, the male and female shapes constituting the cooperating shapes mutuality of the modules. The female forms are preferably made by alternating male forms.

Deux modules présentant leur paroi verticale respective associée comportent des formes mâles en vis-à-vis qui sont agencées en quinconce.Two modules having their respective associated vertical wall comprise male shapes facing each other which are arranged in staggered rows.

Les formes mâles et femelles sont disposées sur chacune des parois verticales d'un module devant coopérer avec les parois verticales d'un autre module.The male and female shapes are arranged on each of the vertical walls of a module which must cooperate with the vertical walls of another module.

Les formes de coopération mutuelle comportent une alternance de formes mâles et femelles, de préférence sous la forme de créneaux droits, s'étendant en hauteur depuis l'arête inférieure d'un module, et à distance de l'arête supérieure opposée,The forms of mutual cooperation comprise an alternation of male and female forms, preferably in the form of straight slots, extending in height from the lower edge of a module, and at a distance from the opposite upper edge,

Les formes de coopération mutuelle comportent des formes mâles dont l'épaisseur (dimension en saillie dans un plan horizontal) est de l'ordre de préférence d'au plus 20 mm. Dans un mode de réalisation particulier, les formes de coopération mutuelle comportent des formes en queue d'aronde. Les formes en queue d'aronde rentrent ou font saillie transversalement à un paroi verticale d'un module. De préférence, les formes de coopération mutuelle comportent la combinaison d'au moins une forme (mâle ou femelle) de géométrie en queue d'aronde et d'une alternance de formes parallélépipédiques mâles et femelles qui sont agencées de part et d'autre de la forme en queue d'aronde.The forms of mutual cooperation comprise male forms whose thickness (dimension projecting in a horizontal plane) is of the order of preference of at most 20 mm. In a particular embodiment, the mutual cooperation shapes include dovetail shapes. The dovetail shapes enter or protrude transversely to a vertical wall of a module. Preferably, the forms of mutual cooperation comprise the combination of at least one form (male or female) of dovetail geometry and an alternation of parallelepiped male and female forms which are arranged on either side of the dovetail shape.

Un module comporte au moins sur l'une de ses parois verticales une forme en queue d'aronde, et de préférence de part et d'autre de la forme en queue d'aronde, une alternance de formes parallélépipédiques mâles et femelles. Selon la place du module dans le dispositif ralentisseur, la forme en queue d'aronde constitue soit une forme mâle, soit une forme femelle.A module comprises at least on one of its vertical walls a dovetail shape, and preferably on either side of the dovetail shape, an alternation of male and female parallelepipedic shapes. Depending on the place of the module in the retarder device, the dovetail shape constitutes either a male shape or a female shape.

La forme en queue d'aronde s'étend sur toute la hauteur (de la face inférieure à la face supérieure) du module.The dovetail shape spans the full height (from bottom to top) of the module.

De manière non évidente, le demandeur a montré que la forme en queue d'aronde confère un auto-blocage extrêmement performant des modules entre eux, et cela dans les trois directions de l'espace, évitant au cours du temps un risque d'écartement des modules tout en fournissant une résistance à la flexion de l'ensemble du dispositif ralentisseur. La combinaison des formes en queue d'aronde et des formes parallélépipédiques (en créneau) renforce encore davantage la fonction autobloquante des modules.In a non-obvious way, the applicant has shown that the dovetail shape confers extremely high-performance self-locking of the modules to each other, and this in the three directions of space, avoiding over time a risk of separation modules while providing resistance to bending of the entire retarder device. The combination of dovetail shapes and parallelepipedic (slot) shapes further enhances the self-locking function of the modules.

Avantageusement, les formes de coopération mutuelle sont intégrées dans le corps des modules, de préférence sont en béton, notamment en étant issues de la fabrication des modules, en particulier de la fabrication par moulage des modules.Advantageously, the forms of mutual cooperation are integrated into the body of the modules, preferably are made of concrete, in particular by being derived from the manufacture of the modules, in particular from the manufacture by molding of the modules.

Selon encore une autre caractéristique, le dispositif comporte d'une part au moins un module, de préférence au moins deux, voire au moins quatre modules qui sont de forme parallélépipédique à pans droits et constituant la partie centrale du dispositif, et d'autre part des modules périphériques qui sont adjacents et entourent la partie centrale, et présentent chacun au moins un pan incliné en surface supérieure.According to yet another characteristic, the device comprises on the one hand at least one module, preferably at least two, or even at least four modules which are of parallelepipedal shape with straight sides and constituting the central part of the device, and on the other hand peripheral modules which are adjacent and surround the central part, and each have at least one inclined face on the upper surface.

Dans un mode de réalisation particulier, le dispositif ralentisseur comporte

  • pour la partie centrale, au moins deux types de modules parallélépipédiques à pans droits :
    • le premier type de module comporte au moins une forme femelle en queue d'aronde sur chacune de trois de ses parois verticales tandis que la quatrième paroi verticale comporte au moins une forme mâle en queue d'aronde ;

Le dispositif routier ralentisseur 1 illustré sur la figure 1 est du type coussin berlinois. Il est en béton. Il est destiné à être installé sur le sol avec une couche de bitume 2 venant à fleur de son pourtour périphérique 10.The road retarder device 1 illustrated in the figure 1 is of the speed bump type. It is concrete. It is intended to be installed on the ground with a layer of bitumen 2 flush with its peripheral perimeter 10.

Il comporte une partie centrale 1A de surface supérieure plane horizontale, et une partie périphérique 1B entourant l'ensemble de la partie centrale 1A et présentant une surface supérieure qui comporte une portion horizontale dans la continuité de la surface horizontale de la partie centrale, et une portion à pans inclinés vers le sol.It comprises a central part 1A with a flat horizontal upper surface, and a peripheral part 1B surrounding the whole of the central part 1A and having an upper surface which comprises a horizontal portion in the continuity of the horizontal surface of the central part, and a portion with sloped sides towards the ground.

Le dispositif 1 comporte selon l'invention une pluralité de modules en béton assemblés les uns aux autres par des moyens de coopération mutuelle agencés sur leurs parois verticales d'association, qui seront détaillés plus loin.The device 1 comprises according to the invention a plurality of concrete modules assembled to each other by means of mutual cooperation arranged on their vertical association walls, which will be detailed below.

Plus particulièrement, le dispositif 1 comporte des modules 3-1, 3-2, 3-3, 3-4, dits modules centraux et ici au nombre de quatre, formant la partie centrale 1A, et des modules 4-1 à 4-8, dits modules périphériques et ici au nombre de huit, formant la partie périphérique 1B.More particularly, the device 1 comprises modules 3-1, 3-2, 3-3, 3-4, called central modules and here four in number, forming the central part 1A, and modules 4-1 to 4- 8, called peripheral modules and here eight in number, forming the peripheral part 1B.

Les modules centraux 3-1 à 3-4 de la partie centrale ont la forme de parallélépipèdes droits (figure 2) comportant chacun deux faces opposées horizontales supérieure 30 et inférieure 31, et quatre parois latérales verticales périphériques 32, 33, 34, et 35 reliant les deux faces. Chaque module central possède une hauteur imposée à l'utilisation visée. Par exemple, cette hauteur est de l'ordre de 200 mm.The central modules 3-1 to 3-4 of the central part have the shape of straight parallelepipeds ( figure 2 ) each comprising two opposite horizontal upper 30 and lower 31 faces, and four peripheral vertical side walls 32, 33, 34, and 35 connecting the two faces. Each central module has a height imposed on the intended use. For example, this height is of the order of 200 mm.

Chaque module central 3-1 à 3-4 est entouré sur chacun de ses quatre côtés d'un autre module, en particulier de deux modules centraux et de deux modules périphériques.Each central module 3-1 to 3-4 is surrounded on each of its four sides by another module, in particular two central modules and two peripheral modules.

Le modules périphériques 4-1 à 4-8 comportent des modules dits longitudinaux 4-1, 4-2, 4-5 et 4-6 s'étendant selon la longueur des modules centraux, et des modules de coins 4-3, 4-4, 4-7 et 4-8 qui sont assemblés aux extrémités distales du dispositif.The peripheral modules 4-1 to 4-8 comprise so-called longitudinal modules 4-1, 4-2, 4-5 and 4-6 extending along the length of the central modules, and corner modules 4-3, 4 -4, 4-7 and 4-8 which are assembled at the distal ends of the device.

Chaque module périphérique présente deux faces opposées supérieure 40 et inférieure 41 et quatre parois verticales périphériques 42 à 45 reliant les deux faces. La face supérieure 40 possède soit un pan incliné 40-1 vers le sol et vers l'extérieur du dispositif (pour un module longitudinal du type 4-1 ou 4-6), soit deux pans inclinés 40-1 et 40-2 (pour un module de coin du type 4-3 ou 4-7).Each peripheral module has two opposite upper 40 and lower 41 faces and four peripheral vertical walls 42 to 45 connecting the two faces. The upper face 40 has either an inclined face 40-1 towards the ground and towards the outside of the device (for a longitudinal module of the 4-1 or 4-6 type), or two inclined faces 40-1 and 40-2 ( for a 4-3 or 4-7 type corner module).

La hauteur d'un module périphérique n'est pas la même sur l'ensemble de son pourtour, en raison de la ou des pentes imposées. Sa plus grande hauteur correspond à la hauteur d'un module central, et cela pour ses portions en contact avec un module central, tandis que les autres portions déclinent jusqu'à une hauteur basse d'extrémité destinée à être en contact et à fleur avec le bitume 2. Cette hauteur d'extrémité basse est par exemple de l'ordre de 100 mm.The height of a peripheral module is not the same over its entire perimeter, due to the slope(s) imposed. Its greatest height corresponds to the height of a central module, and this for its portions in contact with a central module, while the other portions decline to a low end height intended to be in contact and flush with bitumen 2. This low end height is for example of the order of 100 mm.

Le nombre de modules centraux et périphériques est donné ici à titre d'exemple uniquement illustratif et nullement limitatif. Leur nombre dépendra de la taille du dispositif.The number of central and peripheral modules is given here by way of illustrative example only and in no way limiting. Their number will depend on the size of the device.

A titre d'exemple, un module central présente des dimensions dans un plan horizontal, de 1000 mm par 500 mm; un module périphérique présente une longueur dans un plan horizontal, qui correspond au moins à la longueur d'un module central ou à la combinaison de la largeur d'un module central et de la largeur d'un module longitudinal périphérique.By way of example, a central module has dimensions in a horizontal plane of 1000 mm by 500 mm; a peripheral module has a length in a horizontal plane, which corresponds at least to the length of a central module or to the combination of the width of a central module and the width of a peripheral longitudinal module.

Selon l'invention et en regard des figures 2 à 4, les modules sont assemblés entre eux par des formes de coopération mutuelle 50 et 51 constituant des moyens mécaniques autobloquants des modules entre eux. Ces formes de coopération mutuelle assurent un blocage dans un plan horizontal des modules entre eux. Les modules ne peuvent s'écarter les uns des autres aux cours du temps.According to the invention and with regard to figures 2 to 4 , the modules are assembled together by forms of mutual cooperation 50 and 51 constituting self-locking mechanical means of the modules between them. These forms of mutual cooperation ensure blocking in a horizontal plane of the modules between them. The modules cannot deviate from each other over time.

Les parois verticales de deux modules assemblés sont intimement plaquées l'une contre l'autre.The vertical walls of two assembled modules are tightly pressed against each other.

Les formes de coopération mutuelle 50 et 51 sont de préférence intégrées dans le corps des modules. Elles sont issues de préférence lors de la fabrication des modules, en particulier lors de la fabrication par moulage des modules. Elles sont de préférence également en béton. Les formes de coopération mutuelle 50 et 51 sont agencées sur au moins une paroi latérale d'un module, en particulier sur chacune des parois qui est à associer à la paroi d'un module adjacent.The forms of mutual cooperation 50 and 51 are preferably integrated into the body of the modules. They are preferably obtained during the manufacture of the modules, in particular during the manufacture by molding of the modules. They are preferably also made of concrete. The forms of mutual cooperation 50 and 51 are arranged on at least one side wall of a module, in particular on each of the walls which is to be associated with the wall of an adjacent module.

Les formes de coopération mutuelle 50 et 51 sont établies par une alternance de formes mâles unitaires espacées 50 qui délimitent entre elles des formes femelles. Ici, les formes mâles 50 sont en saillie de la paroi latérale, tandis que les formes femelles 51 correspondent à la surface de la paroi.The forms of mutual cooperation 50 and 51 are established by an alternation of spaced unitary male forms 50 which delimit female forms between them. Here, the male forms 50 protrude from the side wall, while the female forms 51 correspond to the surface of the wall.

Les formes mâles 50 sont par exemple en forme de carrés ou rectangles, comme en créneaux, et s'étendent à partir de l'arête inférieure d'un module sans s'étendre jusqu'en haut du module. Les formes mâles 50 présentent par exemple une hauteur correspondant à la moitié de la hauteur maximale du module.The male shapes 50 are for example in the shape of squares or rectangles, as in slots, and extend from the lower edge of a module without extending to the top of the module. The male shapes 50 have for example a height corresponding to half the maximum height of the module.

Les formes mâles sont par exemple espacées entre 70 et 150 mm.The male forms are for example spaced between 70 and 150 mm.

Avantageusement, les formes mâles 50 de deux parois en vis-à-vis (figures 3 et 4), telles que 33 et 35, respectivement de deux modules adjacents, tels que les modules centraux respectifs 3-4 et 3-1, sont disposées en quinconce.Advantageously, the male shapes 50 of two facing walls ( figures 3 and 4 ), such as 33 and 35, respectively of two adjacent modules, such as the respective central modules 3-4 and 3-1, are staggered.

De plus, afin de permettre un assemblage à partir de modules standardisés sans avoir à se préoccuper du sens de montage, chaque module présente au moins deux parois verticales consécutives à associer, telles que 32 et 33 ou 33 et 34, qui sont dotées des moyens de coopération mutuelle 50 et 51, lesdits moyens de coopération mutuelle 50 et 51 étant agencés de façon que l'extrémité d'une paroi d'un module se termine par une forme complémentaire de la forme par laquelle commence la paroi consécutive de ce même module. Ainsi, si l'une des parois, telle que la paroi 32 (par exemple du module 3-4 des figures 2 et 3) se termine par une forme mâle 50, la paroi 33 qui suit (celle ayant l'arête de coin en commun) débute par une forme femelle 51. En outre, chaque paroi dotée des moyens de coopération mutuelle 50 et 51 possède sa première extrémité en bord ou à proximité immédiate d'un coin, qui comprend une forme mâle, tandis que sa seconde extrémité opposée comporte une forme femelle (c'est-à-dire que si la paroi commence par une forme mâle, elle se termine par une forme femelle).In addition, in order to allow assembly from standardized modules without having to worry about the direction of assembly, each module has at least two consecutive vertical walls to be associated, such as 32 and 33 or 33 and 34, which are equipped with means of mutual cooperation 50 and 51, said mutual cooperation means 50 and 51 being arranged so that the end of a wall of a module ends with a shape complementary to the shape with which the consecutive wall of this same module begins . Thus, if one of the walls, such as wall 32 (for example of module 3-4 of figure 2 and 3 ) ends with a male form 50, the wall 33 which follows (the one having the corner edge in common) begins with a female form 51. In addition, each wall provided with the means of mutual cooperation 50 and 51 has its first end at or near a corner, which comprises a male shape, while its opposite second end comprises a shape female (i.e. if the wall begins with a male shape, it ends with a female shape).

Concernant la mise en œuvre des modules, chaque module à associer à un ou des modules déjà en place se fait en amenant le module de sorte à positionner ses formes mâles 50 au droit (à la verticale) des formes femelles 51 du ou des modules déjà installés sur le sol, et à emboîter ledit module par translation verticale dans le ou les modules adjacents. Les modules ainsi en place, sont auto-bloqués ; ils procurent un dispositif unitaire en béton sans être monolithique, favorisant via la pluralité de modules la résistance à la flexion dudit dispositif.Concerning the implementation of the modules, each module to be associated with one or more modules already in place is done by bringing the module so as to position its male shapes 50 to the right (vertically) of the female shapes 51 of the module or modules already installed on the ground, and fitting said module by vertical translation into the adjacent module or modules. The modules thus in place are self-locking; they provide a unitary concrete device without being monolithic, favoring via the plurality of modules the resistance to bending of said device.

La figure 5 montre un autre exemple de réalisation du dispositif ralentisseur 1, pour lequel les modules ont des formes principales mâles et femelles sur au moins une paroi verticale, qui présentent une géométrie en queue d'aronde.The figure 5 shows another embodiment of the retarder device 1, for which the modules have main male and female shapes on at least one vertical wall, which have a dovetail geometry.

Le dispositif 1 comporte, tout comme dans la figure 1, un nombre approprié de modules pour constituer d'une part, la partie centrale 1A plane faite de modules 3-1, 3-2, 3-3, 3-4, dits modules centraux et ici au nombre de quatre, et d'autre part, la partie périphérique 1B à pans inclinés, faite des modules 4-1 à 4-8, dits modules périphériques et ici au nombre de huit.The device 1 comprises, as in the figure 1 , an appropriate number of modules to constitute on the one hand, the flat central part 1A made of modules 3-1, 3-2, 3-3, 3-4, called central modules and here four in number, and on the other hand, the peripheral part 1B with inclined faces, made up of modules 4-1 to 4-8, called peripheral modules and here eight in number.

De plus, dans cet exemple, comme visible en regard des figures 6 à 8, les formes en queue d'aronde mâles 52 et femelles 53 sont complétées par les formes parallélépipédiques mâles 50 et femelles 51 décrites dans l'exemple des figures 1 à 4.Moreover, in this example, as seen next to the figures 6 to 8 , the male 52 and female 53 dovetail shapes are supplemented by the parallelepipedic male 50 and female 51 shapes described in the example of the figures 1 to 4 .

La forme mâle en queue d'aronde 52 fait saillie transversalement à la paroi verticale associée. La forme femelle en queue d'aronde 53 engendre un décrochement intérieur transversal à la paroi verticale.The male dovetail shape 52 projects transversely to the associated vertical wall. The female dovetail shape 53 generates an interior recess transverse to the vertical wall.

Les formes en queue d'aronde 52 et 53 agencées sur une paroi verticale s'étendent selon toute la hauteur du module, tandis que les formes parallélépipédiques 50 et 51 ne s'étendent que sur une partie de la hauteur (de la face inférieure à distance de la face supérieure).The dovetail shapes 52 and 53 arranged on a vertical wall extend along the entire height of the module, while the parallelepiped shapes 50 and 51 extend only over part of the height (from the lower face to distance from the top face).

De préférence, lorsque la forme en queue d'aronde est unitaire sur une paroi, sa longueur est de l'ordre de la moitié de la longueur de la paroi. De préférence, la profondeur de la queue d'aronde/l'avancée de la queue d'aronde est de l'ordre de 40 mm.Preferably, when the dovetail shape is unitary on a wall, its length is of the order of half the length of the wall. Preferably the dovetail depth/dovetail projection is of the order of 40mm.

Pour la fabrication du dispositif ralentisseur 1, plusieurs types de modules sont préfabriqués pour être ensuite directement assemblés sur place. La figure 5 montre que cinq types de modules référencés A, B, C, D et E sont nécessaires.For the manufacture of the retarder device 1, several types of modules are prefabricated to then be directly assembled on site. The figure 5 shows that five types of modules referenced A, B, C, D and E are required.

Pour la partie centrale 1A, deux types de modules B et C sont préfabriqués. La figure 6 illustre le module B. Le module C correspond au module B avec cependant ses formes qui sont complémentaires aux formes du module B. Comme illustré, le module B de forme parallélépipédique rectangle comporte sur trois de ses parois verticales une forme femelle 53 en queue d'aronde, tandis que la quatrième paroi comporte une forme mâle 52 en queue d'aronde. Seules les parois verticales longitudinales comportent en outre une alternance des formes parallélépipédiques mâles 50 et femelles 51.For the central part 1A, two types of modules B and C are prefabricated. The figure 6 illustrates module B. Module C corresponds to module B with, however, its shapes which are complementary to the shapes of module B. dovetail, while the fourth wall has a male shape 52 dovetail. Only the longitudinal vertical walls further comprise an alternation of male 50 and female 51 parallelepipedic shapes.

Pour la partie périphérique 1B et les modules longitudinaux 4-1, 4-2, 4-3 et 4-5, un seul type de module A est fabriqué et illustré sur la figure 7. Seules les trois parois verticales devant être associées aux autres modules sont pourvues de formes mâles et femelles. Seule la paroi longitudinale devant coopérer avec la partie centrale 1A est dotée d'une forme mâle 52 en queue d'aronde et de formes mâles 50 et femelles parallélépipédiques de part et d'autre de la forme en queue d'aronde, tandis que les parois adjacentes sont dotées de formes mâles 50 et femelles 51 uniquement parallélépipédiques.For the peripheral part 1B and the longitudinal modules 4-1, 4-2, 4-3 and 4-5, only one type of module A is manufactured and illustrated on the figure 7 . Only the three vertical walls to be associated with the other modules are provided with male and female shapes. Only the longitudinal wall that must cooperate with the central part 1A has a male 52 dovetail shape and male 50 and parallelepiped female shapes on either side of the dovetail shape, while the adjacent walls are provided with male 50 and female 51 only parallelepipedic forms.

De plus, deux types de modules d'angle ou de coin D et E (figure 5) sont nécessaires pour fournir aux angles du dispositif des pentes opposées. Les modules D et E sont symétriques. Chaque module D ou E comporte deux parois verticales adjacentes et intérieures qui coopèrent respectivement, pour l'une avec un module de la partie centrale 1A et un module longitudinal de la partie périphérique 1B, et pour l'autre avec l'autre module de coin de la partie périphérique. Bien entendu, si le dispositif ralentisseur était plus large, les modules de coins coopéreraient avec au moins un module longitudinal disposé en interface. La figure 8 montre le module de type E. Chaque module D, E présente sur sa paroi verticale destinée à coopérer avec la partie centrale 1A, d'une part, une forme femelle 53 en queue d'aronde destinée à coopérer avec une forme mâle en queue d'aronde 52 d'un module B ou C de la partie centrale, et d'autre part, une alternance de formes mâles 50 et femelles 51 parallélépipédiques pour coopérer avec les formes complémentaires opposées d'un module B ou C de la partie centrale, et d'un module A de la partie périphérique. La seconde paroi verticale d'une module D ou E, qui coopère avec l'autre module opposé de coin de la partie périphérique présente uniquement des formes mâles 50 et femelles 51 parallélépipédiques.In addition, two types of corner or corner modules D and E ( figure 5 ) are necessary to provide the corners of the device with opposite slopes. Modules D and E are symmetrical. Each module D or E comprises two adjacent and inner vertical walls which cooperate respectively, for one with a module of the central part 1A and a longitudinal module of the peripheral part 1B, and for the other with the other corner module of the peripheral part. Of course, if the retarder device were wider, the corner modules would cooperate with at least one longitudinal module arranged at the interface. The figure 8 shows the type E module. Each module D, E has on its vertical wall intended to cooperate with the central part 1A, on the one hand, a female form 53 in dovetail intended to cooperate with a male form in tail d dovetail 52 of a module B or C of the central part, and on the other hand, an alternation of parallelepipedal male 50 and female 51 shapes to cooperate with the opposite complementary shapes of a module B or C of the central part, and a module A of the peripheral part. The second vertical wall of a module D or E, which cooperates with the other opposite corner module of the peripheral part only has male 50 and female 51 parallelepipedic shapes.
