Description

La présente invention a pour objet un moyen de liaison pour la jonction de deux pièces de voirie adjacentes destinées à être posées sur une structure support comme par exemple les grilles caniveaux chaînées ou les trappes de fosses.The subject of the present invention is a connecting means for joining two adjacent road parts intended to be placed on a support structure such as, for example, chain gates or chase traps.

Dans les environnements tels que les aéroports, le trop plein des piscines, les sols des immeubles dans lesquels on utilise l'eau pour diverses opérations ou même les rues des villes ou les autoroutes, il est courant d'utiliser des caniveaux pour l'évacuation de l'eau. Ces caniveaux ont généralement une bordure coulée en béton sur laquelle on fixe deux longerons métalliques destinés à supporter les pièces de voirie.In environments such as airports, overflow pools, the floors of buildings in which water is used for various operations or even city streets or highways, it is common to use gutters for drainage some water. These gutters generally have a poured concrete edge on which two metal beams are fixed intended to support the road parts.

Dans le cas de sol d'immeuble ou de trop plein de piscine, les pièces de voirie, par exemple des grilles, sont simplement posées les unes à côté des autres sur les longerons.In the case of building floors or swimming pool overflows, the road parts, for example grids, are simply placed next to each other on the side rails.

Dans le cas des aéroports, des bordures d'autoroutes ou des rues des villes, lorsque les pièces de voirie sont simplement posées sur les longerons, elles risquent d'en être soulevées et éjectées lors du passage d'un véhicule ce qui présente un réel danger.In the case of airports, highway curbs or city streets, when the road parts are simply placed on the side rails, they risk being lifted and ejected during the passage of a vehicle which presents a real danger.

Une solution au problème est de lier les pièces de voirie aux longerons qui les supportent. Mais, étant donné que lesdits longerons sont eux-mêmes fixés légèrement sur une structure en béton, ils ne peuvent reprendre une charge élevée. Cette solution est donc peu fiable.One solution to the problem is to link the road parts to the side members which support them. However, since the said beams are themselves fixed slightly on a concrete structure, they cannot take up a high load. This solution is therefore not very reliable.

Une autre solution couramment utilisée est de lier les pièces de voirie les unes aux autres.Another commonly used solution is to link the road parts to each other.

Il est connu pour lier les pièces de voirie entre elles d'utiliser des moyens mécaniques tels que des vis de chaînage qui permettent de solidariser les deux pièces contiguës.It is known to link the road parts together using mechanical means such as chaining screws which allow the two adjoining parts to be joined.

L'inconvénient de ce type de moyen de liaison réside dans la nécessité d'utiliser des éléments rapportés. De plus, les pièces de voirie étant généralement posées dans un environnement où s'accumulent poussières et crasses, les vis de chaînage se grippent et leur manoeuvre devient très difficile lorsqu'il est nécessaire de démonter les pièces pour intervenir sur le réseau.The disadvantage of this type of connection means lies in the need to use added elements. In addition, road parts are generally installed in an environment where dust and dirt accumulate, chaining screws seize up and their maneuver becomes very difficult when it is necessary to dismantle the parts to intervene on the network.

Une autre solution consiste à utiliser des pièces de voirie dont les faces d'extrémités en contact avec les pièces voisines sont munies de doigts horizontaux également répartis.Another solution consists in using road parts whose end faces in contact with the neighboring parts are provided with equally distributed horizontal fingers.

D'un côté de la pièce, les doigts d'extrémité sont à un niveau supérieur à celui du doigt médian et c'est l'inverse de l'autre côté. Ainsi, lors du montage des pièces, les doigts supérieurs en vis-à-vis avec les doigts inférieurs, chaque doigt inférieur est retenu par le doigt supérieur correspondant de la pièce voisine.On one side of the room, the end fingers are at a level higher than that of the middle finger and it is the opposite on the other side. Thus, during the assembly of the parts, the upper fingers vis-à-vis with the lower fingers, each lower finger is retained by the corresponding upper finger of the neighboring part.

L'inconvénient de ce type de moyen de liaison réside dans le fait que, pour monter ou démonter une pièce de voirie munie de tels moyens, il faut maintenir à la main deux pièces soulevées. Or une pièce moyenne pèse environ 40 kg.The disadvantage of this type of connection means lies in the fact that, to mount or dismount a road part provided with such means, it is necessary to hold two raised parts by hand. However an average piece weighs about 40 kg.

La présente invention a pour objet des moyens de liaison pour la jonction de deux pièces de voirie qui permettent de s'affranchir de ces inconvénients.The present invention relates to connecting means for the junction of two parts of road which allow to overcome these drawbacks.

La présente invention concerne plus particulièrement des moyens de liaison pour la jonction de deux pièces de voirie adjacentes destinées à être posées sur une structure support, par exemple un caniveau d'écoulement ou un cadre de trappe à multivantaux, constitués par un élément déformable élastiquement d'une des pièces à joindre et par un doigt saillant de l'autre pièce. L'élément déformable élastiquement est un barreau situé à une extrémité de la pièce et le doigt saillant présente un bourrelet dont la taille est supérieure à la distance entre le barreau élastique et le reste de la pièce lorsque le barreau est en position de repos.The present invention relates more particularly to connecting means for joining two adjacent road parts intended to be placed on a support structure, for example a drainage channel or a multi-channel trap frame, constituted by an elastically deformable element of 'one of the pieces to be joined and by a protruding finger from the other piece. The elastically deformable element is a bar located at one end of the part and the projecting finger has a bead whose size is greater than the distance between the elastic bar and the rest of the part when the bar is in the rest position.

La présente invention concerne également une pièce présentant lesdits moyens de liaisons qui comporte à l'une de ses extrémités au moins un barreau déformable élastiquement et à l'extrémité opposée au moins un doigt saillant.The present invention also relates to a part having said connecting means which comprises at one of its ends at least one deformable bar elastically and at the opposite end at least one protruding finger.

D'autres caractéristiques et avantages apparaîtront au cours de la description qui va suivre, donnée uniquement à titre d'exemple, faite en référence aux dessins annexés dans lesquels :

  • - la Fig. 1 est une vue de dessus d'un exemple de réalisation d'une pièce de voirie présentant les moyens de liaison selon l'invention ;
  • - la Fig. 2 est une vue en coupe 2-2 de la Fig. 1 ;
  • - la Fig. 3 est une vue de deux pièces de voirie liées par un exemple de réalisation des moyens de liaison selon l'invention.
Other characteristics and advantages will become apparent during the description which follows, given solely by way of example, made with reference to the appended drawings in which:
  • - Fig. 1 is a top view of an embodiment of a road part having the connecting means according to the invention;
  • - Fig. 2 is a sectional view 2-2 of FIG. 1;
  • - Fig. 3 is a view of two road parts linked by an embodiment of the connecting means according to the invention.

Les moyens de liaison pour la jonction de deux pièces de voirie adjacentes destinées à être posées sur une structure support telle qu'un caniveau d'écoulement ou un cadre de trappe à multivantaux sont constitués par un élément déformable élastiquement par exemple un barreau rapporté ou monobloc avec la pièce de voirie et un doigt saillant, rapporté ou monobloc avec l'autre pièce, présentant un bourrelet dont la taille est supérieure à la distance entre le barreau élastique et le reste de la pièce, lorsque ledit barreau est en position de repos.The connecting means for the junction of two adjacent road parts intended to be placed on a support structure such as a drainage channel or a multi-channel trap frame consist of an elastically deformable element, for example an attached or monobloc bar with the road part and a projecting finger, attached or integral with the other part, having a bead whose size is greater than the distance between the elastic bar and the rest of the part, when said bar is in the rest position.

La liaison des deux pièces de voirie adjacentes s'effectue en encliquetant le doigt saillant de la première pièce entre le barreau élastique et le reste de la seconde pièce. Etant donné la taille du bourrelet dont est muni le doigt saillant, lorsque l'on présente ledit doigt dans l'intervalle libre entre le barreau et le reste de la pièce de la seconde pièce de voirie, le barreau se déforme laissant ainsi passer le bourrelet et reprend ensuite sa position de repos emprisonnant ainsi le doigt saillant de la première pièce entre le barreau et le reste de la seconde pièce de voirie.The two adjacent road parts are connected by snapping the protruding finger of the first part between the elastic bar and the rest of the second part. Given the size of the bead with which the protruding finger is provided, when said finger is presented in the free space between the bar and the rest of the part of the second road part, the bar is deformed thus allowing the bead to pass and then resumes its rest position thus trapping the projecting finger of the first part between the bar and the rest of the second road part.

En réalisant ainsi une liaison de chaque pièce, avec ses pièces adjacentes, on réalise un "chaînage" des pièces de voirie.By thus making a connection of each part, with its adjacent parts, one realizes a "chaining" of the road parts.

L'exemple de réalisation d'une pièce de voirie munie des moyens de liaison selon l'invention représentée Fig. 1 est une grille rectangulaire 1 constituée d'une série de barres transversales 2 liées entre elles par trois entretoises longitudinales, l'une centrale 3 et deux autres 4 et 5 à chaque extrémité.The exemplary embodiment of a road part provided with the connecting means according to the invention shown in FIG. 1 is a rectangular grid 1 consisting of a series of transverse bars 2 linked together by three longitudinal spacers, one central 3 and two others 4 and 5 at each end.

A une extrémité de la grille, la dernière barre transversale 6 constituée en un matériau élastique n'est liée à sa barre adjacente que par l'entretoise centrale 3. Chacune de ses extrémités est donc libre et non liée à l'extrémité correspondante de la barre adjacente. La barre d'extrémité 6 est ainsi constituée de deux barreaux élastiques 6a, 6b.At one end of the grid, the last transverse bar 6 made of an elastic material is linked to its adjacent bar only by the central spacer 3. Each of its ends is therefore free and not linked to the corresponding end of the adjacent bar. The end bar 6 thus consists of two elastic bars 6a, 6b.

Chaque extrémité 7, 8 des barreaux d'extrémité 6a, 6b présente un épaulement 9 sur la face supérieure.Each end 7, 8 of the end bars 6a, 6b has a shoulder 9 on the upper face.

L'extrémité opposée de la grille 1 présente deux doigts saillants longitudinaux 10, 11 dans le prolongement des entretoises 4 et 5.The opposite end of the grid 1 has two longitudinal projecting fingers 10, 11 in the extension of the spacers 4 and 5.

Chaque doigt 10, 11 présente à son extrémité un bourrelet 12 faisant saillie vers le bas précédé d'une emboîture 13 ménagée sur sa face inférieure.Each finger 10, 11 has at its end a bead 12 projecting downwardly preceded by a socket 13 formed on its underside.

Le bourrelet 12 a une dimension longitudinale supérieure à la distance d entre l'extrémité libre des barreaux 6a, 6b et le reste de la grille 1.The bead 12 has a longitudinal dimension greater than the distance d between the free end of the bars 6a, 6b and the rest of the grid 1.

L'emboîture 13 a une dimension légèrement supérieure à celle de l'épaulement 9 dont sont munies les extrémités 7 et 8 du barreau 6 de la grille.The socket 13 has a dimension slightly greater than that of the shoulder 9 with which the ends 7 and 8 of the bar 6 of the grid are provided.

La liaison de deux pièces adjacentes s'effectue en forçant les bourrelets 12 de la première pièce entre les barreaux élastiques 6a, 6b et le reste de la seconde pièce.The connection of two adjacent parts is effected by forcing the beads 12 of the first part between the elastic bars 6a, 6b and the rest of the second part.

Les barreaux élastiques 6a, 6b se déforment dans le plan de la pièce pour laisser passer les bourrelets 12 de l'autre pièce puis reprennent leur position de repos emprisonnant ainsi lesdits bourrelets.The elastic bars 6a, 6b are deformed in the plane of the part to allow the beads 12 of the other part to pass, then resume their rest position thus trapping said beads.

Lorsque la pièce est posée, l'épaulement dont sont munies les extrémités 7, 8 du barreau élastique de la première pièce s'emboîtent dans l'emboîture 13 dont sont munies les doigts 10, 11 de la seconde pièce.When the part is installed, the shoulder with which the ends 7, 8 of the elastic bar of the first part fit into the socket 13 which are provided with the fingers 10, 11 of the second part.

Ainsi chaque doigt de chaque grille est emprisonné sous la grille adjacente et on réalise ainsi un chaînage de toutes les grilles.Thus each finger of each grid is trapped under the adjacent grid and a chaining of all the grids is thus carried out.

Les avantages de la présente invention sont les suivants :
- elle ne nécessite aucun élément rapporté ;
- toutes les pièces sont identiques ;
- il est impossible de placer les grilles à l'envers ;
- la mise en place est très simple et ne nécessite aucune manipulation particulière. Il suffit de positionner la grille et d'exercer un effort vertical, par exemple en frappant sur la grillepour la lier à la précédente ;
- le démontage d'une grille est simple. Il suffit, à l'aide d'un pied de biche par exemple, de déplacer les barreaux élastiques 6a, 6b jusqu'à ce que les bourrelets 12 puissent passer entre lesdits barreaux et le reste de la grille adjacente, puis de soulever la grille.
- le démontage ne peut être accidentel.The advantages of the present invention are as follows:
- it does not require any additional elements;
- all parts are identical;
- the grids cannot be placed upside down;
- the installation is very simple and does not require any particular manipulation. Just position the grid and exert a vertical force, for example by hitting the grid to link it to the previous one;
- the dismantling of a grid is simple. It suffices, using a crowbar for example, to move the elastic bars 6a, 6b until the beads 12 can pass between said bars and the rest of the adjacent grid, then lift the grid .
- disassembly cannot be accidental.
