Abstract
Description
La présente invention concerne un dispositif de balisage permettant d'assurer la retenue des véhicules de façon temporaire ou permanente. La presente invention est particulierement destinée au domaine router et autoroutier. The present invention relates to a beaconing device making it possible to secure vehicles temporarily or permanently. The present invention is particularly intended for the router and motorway sector.
Les routes et autoroutcs sont equipees de dispositifs de retenue permettant, en cas accident, aux véhicules de rester sur la chaussée. Ces dispositifs sont situés le long des chaussées, en accotement ou en terre-plein central pour séparer physiquement les deux sens de circulation. Le terre-plein central de ce tape de voie est plus connu sous 1' abréviation de TPC. Ces dispositifs de retenue sont réalisés principalement en acier, en béton ou en bois. Dans le cas où ces dispositifs sont installés de façon permanente, ils sont connus sous le nom de dispositifs de retenue permanents. Dans certains cas, lors de chantiers par exemple, on utilise des dispositifs de retenue temporaires également connu sous le nom dc balisage. Roads and motorways are equipped with restraint devices allowing vehicles to stay on the road in the event of an accident. These devices are located along the roadways, on the shoulder or in the central reservation to physically separate the two directions of traffic. The central reservation of this lane is better known by the abbreviation of TPC. These restraint systems are mainly made of steel, concrete or wood. In the case where these devices are installed permanently, they are known as permanent restraining devices. In certain cases, during construction sites, for example, temporary restraint devices also known as buoying are used.
Les dispositifs de retenue temporaire où balisage sont réalisés principalement par des éléments en plastique, en béton ou en métal, liaisonnés entre eux: Les balisages en éléments en plastique, pour avoir une capacité de retenue suffisante, sont lestés au moyen d'eau ou de sable. Cela nécessite, lors de leur installation des manipulations longues et onéreuses pour le remplissage. De plus, dans le cas où l'eau est utilisée, il y a toujours un risque de filite ou de gel. C'est pourquoi, ce type de dispositif est souvent utilise sans Icst. Le dispositif perd alors sa fonction de retenue et il est connu sous Ic nom dc balisage visuel. Temporary restraint systems where beacons are produced mainly by plastic, concrete or metal elements, linked together: The beacons made of plastic elements, to have sufficient holding capacity, are ballasted with water or sand. This requires, during their installation, long and expensive manipulations for filling. In addition, if water is used, there is always a risk of filite or freezing. This is why this type of device is often used without Icst. The device then loses its retaining function and is known by the name of visual beaconing.
Pour assurer une capacité de retenue suffisante et donc une bonne protection des chantiers, on utilise principalement des dispositifs de retenue composés d'éléments en béton, en métal ou mixte métal et béton. Dans le cas des dispositifs tout ou partie en béton, le poids du dispositif assure la fonction de retenue. To ensure sufficient holding capacity and therefore good protection of construction sites, use is mainly made of retaining devices composed of concrete, metal or mixed metal and concrete elements. In the case of all or part concrete devices, the weight of the device ensures the retaining function.
Le poids au mètre linéaire de ce type de dispositifs est de plusieurs centaines de Icilogrammes ce qui occasionne, lors de la mise en plate, des coûts de transport importants. Par contre la capacite de retenue est très bonne et la liaison entre les éléments est simple ct pcut ètre articulée si nécessaire.The weight per linear meter of this type of device is several hundred Icilograms which causes, during flattening, significant transport costs. On the other hand, the retaining capacity is very good and the connection between the elements is simple and can be articulated if necessary.
Lorsque le balisage est en acier, le poids au mètre linéaire est moins important. La capacité de retenue de ces dispositifs est alors assurée par la qualité de la liaison entre les éléments. Si la liaison est trop rigide, le balisage aura une bonne capacité de retenue, mais en contrepartie, il ne pourra pas etr déplace latéralement facilement comme il est nécessaire lors de chantiers demandant un phasage des travaux important On dit alors que le balisage n'est pas transposable. Si la liaison est trop souple. le balisage peut entre transpose facilement, mais sa capacité dc retenue devisent treks faible. C'est pourquol aujourd'hui, les balisages transposables sont essentiellement composés d' éléments en béton. When the markup is made of steel, the weight per linear meter is less important. The retaining capacity of these devices is then ensured by the quality of the connection between the elements. If the link is too rigid, the markup will have a good holding capacity, but in return, it will not be able to move laterally easily as it is necessary during construction sites requiring significant phasing of work. It is said that the markup is not not transposable. If the bond is too flexible. the markup can easily be transposed, but its retention capacity must be very low. This is why today, the transposable markings are essentially composed of concrete elements.
Le dispositif selon l'invention a pour but de réaliser un balisage d'un poids faible tout en assurant une capacité de retenue importante. The purpose of the device according to the invention is to provide low-weight marking while ensuring a high holding capacity.
Le dispositif selon l'invention est compose d'eléments modulaires liaisonnes entre eux selon une preiniere caractenstique de l'invention par un câble qui peut etre tendu. Pour deplacer les elements lors de leur mise n place ou lors d'une transposition dc balisage, le câble est détendu, ce qui permet une manipulation gliale des éléments. Une fois mis en place, le câble est tendu assurant ainsi une liaison rigide entre les éléments et la capacité de retenue nécessaire au balisage. L'ensemble de plusieurs éléments reliés entre eux au moyen d'un câble tendu constitue un tronçon. The device according to the invention is composed of modular elements linked together according to a first characteristic of the invention by a cable which can be stretched. To move the elements when they are put in place or when the markup is transposed, the cable is relaxed, which allows glial manipulation of the elements. Once in place, the cable is stretched, thus ensuring a rigid connection between the elements and the retaining capacity necessary for markup. The set of several elements linked together by means of a tensioned cable constitutes a section.
Selon une deuxième caracteristique de l'invention plusieurs tronçons peuvent etre relies entre eux. n y a alors un chevauchement des câbles de liaison au droit d'un élément dit élément de raccordement, I'élement de raccordement pouvant ou non etre leste. According to a second characteristic of the invention, several sections can be connected together. There is then an overlap of the connecting cables in line with an element called the connection element, the connection element possibly or not being heavy.
Selon une troisième caracteristique de l'invention, les éléments peuvent être empilés les uns sur les autres pour faciliter le transport. According to a third characteristic of the invention, the elements can be stacked on top of each other to facilitate transport.
Selon une quatrième caractéristique de l'invention, les extrémités des tronçons de balisage sont composées d'éléments pouvant être lestés par tout moyen comme eau, sable ou grenaille. Cela permet d'obtenir un ancrage suffisant au extrémités afin d'assurer une capacité de retenue de l'ensemble du dispositif. According to a fourth characteristic of the invention, the ends of the marking sections are composed of elements which can be ballasted by any means such as water, sand or shot. This provides sufficient anchoring at the ends to ensure a retaining capacity of the entire device.
Les figures suivantes permettent de mieux visualiser le dispositifs selon l'invention. The following figures make it possible to better visualize the devices according to the invention.
La figure 1 présente dcux tronçons du dispositif avec les éléments d'extrérmtés, l'élément dc raccordement, les modules et les câbles de liaison. Figure 1 shows two sections of the device with the end elements, the connection element, the modules and the connecting cables.
