Description

Elément de caniveau pour caniveau de drainage pour chausséesChannel element for drainage channel for roadways
La présente invention concerne un élément de caniveau pour caniveau de drainage pour chaussées constitué d'un corps de caniveau en matière thermoplastique à section en forme de « U » dont les extrémités supérieures horizontales des branches sont agencées pour recevoir une feuillure métallique de réception et de maintien d'une grille métallique fixée au corps de caniveau par des moyens de fixation tels que vis/ëcrou. Le caniveau de drainage est réalisé par assemblage desdits éléments de caniveau.The present invention relates to a channel element for a drainage channel for roadways consisting of a channel body of thermoplastic material with a U-shaped section, the horizontal upper ends of the branches of which are arranged to receive a metal rebate for receiving and maintenance of a metal grid fixed to the channel body by fixing means such as screw / nut. The drainage channel is produced by assembling said channel elements.
De tels éléments de caniveau qui peuvent présenter une longueur de 1 m, sont constitués de pièces telles qu'un corps de caniveau, ainsi que de feuillures métalliques et d'une grille réalisée en acier ou en fonte, et de longueur correspondante . Lorsqu'un caniveau de drainage est mis en place sur une chaussée, il subit des efforts longitudinaux et/ou latéraux exercés par les roues de véhicules en virage ou au cours de freinage. En particulier, les forces exercées peuvent provoquer un déplacement et/ou un arrachement des grilles et des feuillures par rapport aux corps de caniveau.Such channel elements which may have a length of 1 m, consist of parts such as a channel body, as well as metal rebates and a grid made of steel or cast iron, and of corresponding length. When a drainage channel is placed on a roadway, it undergoes longitudinal and / or lateral forces exerted by the wheels of vehicles when cornering or during braking. In particular, the forces exerted can cause displacement and / or tearing of the grids and rebates relative to the channel bodies.
Un tel élément de caniveau est en particulier décrit dans EP- A-0 748 903, où on propose un caniveau avec système de verrouillage de la grille de recouvrement. A cet effet, cet élément comporte un corps de caniveau essentiellement en U, une grille de recouvrement disposée sur un bord supérieur du corps de caniveau ainsi qu'une traverse logée par ses extrémités dans les parois latérales internes du corps de caniveau de telle sorte qu'elle se situe à l'intérieur du corps du caniveau à la transversale de l'axe longitudinal de ce dernier. Un alésage est formé dans les parois latérales du caniveau pour recevoir une broche qui passe à travers un orifice de la grille pour être engagé dans l'alésage. La présence des traverses et la fixation de la grille par des organes appropriés dans les alésages ne suffisent pas à éliminer tous les risques d'arrachement ou de déplacement de la grille.Such a channel element is described in particular in EP-A-0 748 903, where a channel is proposed with a locking grid locking system. To this end, this element comprises a channel body essentially in a U shape, a covering grid arranged on an upper edge of the channel body as well as a cross member housed by its ends in the internal lateral walls of the channel body so that 'It is located inside the body of the gutter at the transverse of the longitudinal axis of the latter. A bore is formed in the side walls of the channel to receive a pin which passes through an orifice in the grid to be engaged in the bore. The presence of the crosspieces and the fixing of the grid by suitable members in the bores is not sufficient to eliminate all the risks of tearing or displacement of the grid.
Le document DE-A-298 08197 propose un élément de caniveau du type constitué d'un corps en U dont les parois latérales portent respectivement dans leur partie supérieure une feuillure métallique. Les parois latérales du corps en U comportent respectivement une rainure longitudinale dans laquelle se loge une nervure longitudinale ménagée sur la feuillure métallique. On propose ainsi d'immobiliser encore mieux la feuillure métallique sur le corps de caniveau. Cependant, cette rainure présente une forme arrondie nécessitant une forme complémentaire de la branche de la feuillure venant en regard. Ainsi, on rend plus complexe la fabrication d'un tel élément de caniveau car les formes doivent être en parfaite correspondance pour que le résultat, c'est-à-dire l'immobilisation de la feuillure sur le corps de caniveau, soit la plus performante possible. En outre, un phénomène de glissement longitudinal de la grille peut intervenir le long de la rainure, ce qui ne favorise pas le verrouillage de la grille mais le perturbe au contraire.Document DE-A-298 08197 proposes a channel element of the type consisting of a U-shaped body whose side walls respectively carry in their upper part a metal rebate. The side walls of the U-shaped body respectively have a longitudinal groove in which is housed a longitudinal rib formed on the metal rebate. It is thus proposed to immobilize the metal rebate even better on the channel body. However, this groove has a rounded shape requiring a complementary shape of the branch of the rebate coming opposite. Thus, it makes the manufacture of such a channel element more complex because the shapes must be in perfect correspondence so that the result, that is to say the immobilization of the rebate on the channel body, is the most performance possible. In addition, a longitudinal sliding phenomenon of the grid can occur along the groove, which does not favor the locking of the grid but on the contrary disturbs it.
Dans DE-A-88 04 073.9, on a proposé un élément de caniveau dans lequel la feuillure métallique comporte une aile extérieure pourvue d'une saillie propre à se loger dans une rainure ménagée sur la face extérieure d'une paroi latérale du corps de caniveau. La nervure est ménagée en V sur la face externe d'une paroi latérale du caniveau en U et la saillie est également ménagée en V de manière complémentaire pour se loger dans la rainure. Là encore, on complique le dispositif car l'aile de la feuillure doit présenter la forme complémentaire en V de la rainure en forme de V et, de plus, le glissement longitudinal de la feuillure le long de la rainure n'est pas empêché.In DE-A-88 04 073.9, a channel element has been proposed in which the metal rabbet comprises an outer wing provided with a projection suitable for being housed in a groove formed on the exterior face of a side wall of the body of gutter. The rib is formed in V on the external face of a side wall of the U-shaped channel and the projection is also formed in V in a complementary manner to be housed in the groove. Again, the device is complicated because the wing of the rebate must have the complementary V-shape of the V-shaped groove and, moreover, the longitudinal sliding of the rebate along the groove is not prevented.
Aussi, la fabrication et l'assemblage de ces différents éléments pour former l'élément de caniveau engendrent un coût de fabrication élevé mais de plus, on n'évite pas de manière sûre, les inconvénients liés à la présence des forces exercées par les véhicules et qui peuvent provoquer un déplacement et/ou un arrachement des grilles et des feuillures par rapport aux corps de caniveau.Also, the manufacture and assembly of these different elements to form the channel element generates a high manufacturing cost but moreover, the disadvantages linked to the presence of the forces exerted by the vehicles are not surely avoided. and which can cause displacement and / or tearing of the grids and rebates with respect to the channel bodies.
Afin de pallier ces inconvénients, l'invention a pour but principal de proposer un élément de caniveau dont l'assemblage et le verrouillage des parties métalliques telles que la feuillure et la grille sur le corps de caniveau confèrent audit élément de caniveau, une tenue élevée aux efforts longitudinaux et latéraux exercés par les véhicules sur la chaussée comportant de tels éléments de caniveau.In order to overcome these drawbacks, the main object of the invention is to propose a channel element, the the assembly and locking of the metal parts such as the rebate and the grid on the channel body give said channel element, high resistance to the longitudinal and lateral forces exerted by the vehicles on the roadway comprising such channel elements.
Un autre but tend à proposer également un élément de caniveau dont la fabrication, l'assemblage et le verrouillage de la feuillure et de la grille sont économiquement avantageux.Another object tends to also propose a channel element whose manufacture, assembly and locking of the rebate and the grid are economically advantageous.
A cet effet, l'invention a pour objet un élément de caniveau pour caniveau de drainage pour chaussées, constitué d'un corps de caniveau en matière thermoplastique à section en forme de « U » dont les extrémités supérieures horizontales des branches sont agencées pour recevoir une feuillure métallique de réception et de maintien d'une grille métallique fixée au corps de caniveau par des moyens de fixation tels que vis/écrou, le corps de caniveau présentant au moins un alésage ménagé aux extrémités supérieures horizontales de ses branches pour être en regard d'orifices complémentaires ménagés respectivement dans la feuillure et dans la grille pour recevoir, de préférence avec jeu, une vis de fixation de la grille, caractérisé en ce que le corps de caniveau présente en outre un logement ménagé dans ledit corps de caniveau sous chaque alésage pour recevoir un écrou qui coopère avec une vis tandis qu'au-dessous dudit logement est prévu un autre alésage de diamètre inférieur au diamètre de la vis de manière à créer un frein filet anti-desserage lors de l'assemblage sur le corps de caniveau en thermoplastique, ainsi qu'à chacune de ses extrémités supérieures de branches sur la face verticale interne de celles-ci, une rainure en V à l'intérieur du corps de caniveau, pourvue essentiellement dans sa zone médiane, d'au moins une saillie telle qu'une butée, un bossage ou similaire .To this end, the subject of the invention is a channel element for a drainage channel for roadways, consisting of a channel body of thermoplastic material with a “U” shaped section, the horizontal upper ends of the branches of which are arranged to receive a metal rebate for receiving and holding a metal grid fixed to the channel body by fixing means such as screw / nut, the channel body having at least one bore formed at the horizontal upper ends of its branches so as to be opposite complementary orifices provided respectively in the rebate and in the grid to receive, preferably with clearance, a grid fixing screw, characterized in that the channel body further has a housing formed in said channel body under each bore to receive a nut which cooperates with a screw while below said housing is provided another bore e of diameter less than the diameter of the screw so as to create an anti-loosening thread lock during assembly on the body of the thermoplastic channel, as well as at each of its upper ends of branches on the internal vertical face of those -this, a V-groove inside the channel body, provided essentially in its median zone, with minus a projection such as a stop, a boss or the like.
Selon une forme de réalisation préférée de l'invention, le corps de caniveau présente, en tant que moyens de verrouillage, au moins un alésage ménagé aux extrémités supérieures horizontales de ses branches pour être en regard d'orifices complémentaires ménagés respectivement dans la feuillure et dans la grille pour recevoir une vis de fixation de la grille, ainsi qu'un logement ménagé dans ledit corps de caniveau sous chaque alésage pour recevoir un écrou qui coopère avec une vis et au-dessous dudit logement est prévu un autre alésage de diamètre inférieur au diamètre de la vis.According to a preferred embodiment of the invention, the channel body has, as locking means, at least one bore formed at the horizontal upper ends of its branches so as to be opposite complementary orifices provided respectively in the rebate and in the grid to receive a grid fixing screw, as well as a housing formed in said channel body under each bore to receive a nut which cooperates with a screw and below said housing is provided another bore of smaller diameter to the diameter of the screw.
La vis de fixation est alors engagée au travers de l'orifice de la grille puis de celui de la feuillure et coopère ensuite avec l' écrou, l'extrémité de ladite vis étant engageable dans ledit alésage de diamètre inférieur, lorsque le corps de caniveau est chaud en sortie de presse.The fixing screw is then engaged through the orifice of the grid and then that of the rebate and then cooperates with the nut, the end of said screw being able to be engaged in said bore of smaller diameter, when the channel body is hot at the end of the press.
On recrée ainsi un frein filet anti-desserage du type écrou freiné à bague plastique. Chaque orifice prévu dans la feuillure et la grille accueille la vis avec un jeu, ce jeu étant propre à autoriser le retrait intervenant lors du refroidissement du corps de caniveau. On élimine ainsi toutes contraintes pouvant s'exercer au niveau des vis de fixation, contraintes engendrées par un retrait anarchique du corps de caniveau thermoplastique par rapport aux feuillures métalliques lors du refroidissement.We thus recreate an anti-loosening thread lock of the lock nut type with plastic ring. Each orifice provided in the rebate and the grid receives the screw with a clearance, this clearance being suitable for authorizing the withdrawal occurring during the cooling of the channel body. This eliminates all constraints that may be exerted on the fixing screws, constraints generated by an uncontrolled withdrawal of the thermoplastic channel body relative to the metal rebates during cooling.
De préférence, le corps de caniveau présente à chacune de ses extrémités supérieures des branches, sur la face verticale interne de celles-ci, une rainure en V à l'intérieur du corps de caniveau, pourvue essentiellement dans sa zone médiane, d'au moins une saillie telle qu'une butée, un bossage ou similaire.Preferably, the channel body has at each of its upper ends of the branches, on the internal vertical face of these, a V-groove inside the body channel, provided essentially in its central region, with at least one projection such as a stop, a boss or the like.
De ce fait, la feuillure présente alors au moins une découpe en partie médiane à travers laquelle est engageable avec jeu une saillie de la rainure en V du corps de caniveau, à chaud en sortie de presse dudit corps de caniveau, le jeu entre la découpe et la saillie autorisant le retrait symétrique du corps de caniveau de part et d'autre de ladite saillie.Therefore, the rabbet then has at least one cut in the middle part through which is engaged with play a projection of the V-groove of the channel body, hot at the press outlet of said channel body, the play between the cut and the projection allowing symmetrical withdrawal of the channel body on either side of said projection.
De cette manière, la saillie centrale bloque en translation la feuillure par rapport au corps de caniveau, ce qui engendre une bonne résistance aux efforts latéraux et longitudinaux, tout en autorisant un retrait identique du corps de caniveau de part et d' autre de la saillie lors du refroidissement et, non plus, un retrait à une seule extrémité du corps de caniveau de façon aléatoire .In this way, the central projection blocks in translation the rebate relative to the channel body, which generates good resistance to lateral and longitudinal forces, while allowing identical removal of the channel body on either side of the projection. during cooling and, no longer, a withdrawal at one end of the channel body randomly.
Ainsi, le montage et le verrouillage des parties métalliques que sont la feuillure et la grille sur le corps de caniveau chaud en sortie de presse sont rendus possibles par l'intégration des post-retrait de la matière plastique constituant le corps de caniveau sur toute la longueur de celui-ci par rapport auxdites pièces métalliques rigides verrouillées dans ledit corps de caniveau.Thus, the mounting and locking of the metal parts that are the rebate and the grid on the hot channel body at the press outlet are made possible by the integration of post-shrinkage of the plastic material constituting the channel body over the entire length thereof relative to said rigid metal parts locked in said channel body.
Un élément de caniveau selon l'invention permet d'éviter les glissements longitudinaux et latéraux des grilles lors du passage de véhicules .A channel element according to the invention makes it possible to avoid longitudinal and lateral sliding of the grids during the passage of vehicles.
L'élément de caniveau ainsi formé présente une tenue aux efforts latéraux et longitudinaux élevée ainsi qu'un bon verrouillage et un non-desserrage en réponse aux trépidations routières .The channel element thus formed has a high resistance to lateral and longitudinal forces as well as a good locking and non-loosening in response to hectic roads.
De plus, l'invention a pour objet un procédé d'assemblage d'un élément de caniveau de drainage pour chaussées constitué d'un corps de caniveau à section en forme de « U » dont les extrémités supérieures horizontales de branches sont agencées pour recevoir une feuillure métallique de réception et de maintien d'une grille métallique fixée au corps de caniveau par des moyens de fixation tels que vis/écrou, caractérisé en ce qu'on forme par injection le corps de caniveau en matière thermoplastique, présentant à chacune de ses extrémités supérieures de branches, sur la face verticale interne de celles-ci, une rainure en V à l'intérieur du corps de caniveau et pourvue essentiellement dans sa partie médiane d'au moins une saillie, puis, à chaud en sortie de presse, on met en place, sur chaque extrémité supérieure horizontale des branches du corps de caniveau, une feuillure métallique pourvue d'au moins une découpe en partie médiane à travers laquelle une saillie du corps de caniveau est engagée avec jeu, puis on installe la grille qui est alors fixée à l'aide de vis qui sont engagées avec jeu respectivement dans des orifices ménagés dans la grille et dans la feuillure et dans des alésages ménagés en correspondance dans le corps de caniveau puis qui coopèrent avec des écrous logés dans le corps de caniveau avant d'être engagées dans des alésages ménagés dans le corps de caniveau sous chaque écrou et de diamètre inférieur au diamètre de la vis permettant alors de recréer un frein filet anti-desserage.In addition, the subject of the invention is a method of assembling a drainage channel element for pavements consisting of a channel body with a “U” shaped section, the horizontal upper ends of branches of which are arranged to receive a metal rebate for receiving and holding a metal grid fixed to the channel body by fixing means such as screw / nut, characterized in that the channel body is formed by injection molding in thermoplastic material, each having its upper ends of branches, on the internal vertical face of these, a V-groove inside the channel body and provided essentially in its median part with at least one projection, then, hot at the press outlet , a metal rebate is provided on each horizontal upper end of the branches of the channel body provided with at least one cut in the middle part through which a s the channel body is engaged with clearance, then the grid is installed which is then fixed with screws which are engaged with clearance respectively in orifices formed in the grid and in the rebate and in bores provided correspondingly in the channel body then which cooperate with nuts housed in the channel body before being engaged in bores made in the channel body under each nut and with a diameter less than the diameter of the screw allowing then to recreate an anti thread lock -desserage.

La figure 5 représente une vue en perspective agrandie d'un détail de la figure 1.FIG. 5 represents an enlarged perspective view of a detail of FIG. 1.
Un élément de caniveau 1 selon l'invention est constitué d'un corps de caniveau 2 en matière thermoplastique portant à chacune de ses extrémités supérieures horizontales des branches 2a une feuillure métallique 3 destinée à recevoir une grille métallique 4.A channel element 1 according to the invention consists of a channel body 2 of thermoplastic material carrying at each of its horizontal upper ends of the branches 2a a metal rebate 3 intended to receive a metal grid 4.
Chaque extrémité supérieure d'une branche 2a du corps de caniveau 2 , sur la face verticale interne de ladite branche 2a, présente une rainure 5 en V ouverte vers l'intérieur du corps de caniveau 2. La feuillure 3 présente une forme en « h » obtenue, par exemple par pliage d'une feuille métallique, la petite branche 3a du « h » étant courte et repliée vers l'intérieur.Each upper end of a branch 2a of the channel body 2, on the internal vertical face of said branch 2a, has a V-shaped groove 5 open towards the inside of the channel body 2. The rebate 3 has an “h” shape obtained, for example by folding a metal sheet, the small branch 3a of the “h” being short and folded inwards.
Cette feuillure 3 est positionnée sur l'extrémité supérieure horizontale d'une branche 2a du corps de caniveau 2 de manière à venir pincer ladite extrémité supérieure, la petite branche repliée 3a de la feuillure 3 se logeant dans la rainure 5 en V comme cela est visible aux figures 1 et 4 tandis que l'autre branche 3b de la feuillure 3 s'étend le long de la face externe de la branche 2a du corps de caniveau 2.This rebate 3 is positioned on the horizontal upper end of a branch 2a of the channel body 2 so as to pinch said upper end, the small folded branch 3a of the rebate 3 being housed in the groove 5 in V as is visible in FIGS. 1 and 4 while the other branch 3b of the rebate 3 extends along the external face of the branch 2a of the channel body 2.
Le corps de caniveau 2 présente, en outre, aux extrémités supérieures horizontales de ses branches 2a, des alésages 6 positionnés de manière à être en regard d'orifices 7, 8 complémentaires ménagés respectivement dans la feuillure 3 et la grille 4 pour recevoir une vis de fixation 9 de la grille 4.The channel body 2 has, in addition, at the horizontal upper ends of its branches 2a, bores 6 positioned so as to face opposite orifices 7, 8 formed respectively in the rebate 3 and the grid 4 to receive a screw fixing 9 of the grid 4.
Un écrou 10 est également prévu dans un logement ménagé dans le corps de caniveau 2 dans le prolongement de l'alésage 6 et qui peut coopérer avec la vis 9 lorsque celle-ci est engagée a.u travers de l'orifice 8 de la grille 4 puis de l'orifice 7 de la feuillure 3 puis dans l'alésage 6 du corps de caniveau.A nut 10 is also provided in a housing formed in the channel body 2 in the extension of the bore 6 and which can cooperate with the screw 9 when the latter is engaged through the orifice 8 of the grid 4 then of the opening 7 of the rebate 3 then in the bore 6 of the channel body.
Au-dessous du logement renfermant l' écrou 10, on ménage également un alésage 11 qui présente un diamètre inférieur au diamètre de la vis 9 et dans lequel l'extrémité de la vis 9 peut être engagée lorsque le corps de caniveau 2 est chaud, c'est-à-dire en sortie de presse. L'engagement de la vis 9 dans l'alésage 11 permet de créer un frein filet anti-desserage.Below the housing containing the nut 10, there is also a bore 11 which has a diameter less than the diameter of the screw 9 and in which the end of the screw 9 can be engaged when the channel body 2 is hot, that is to say at the press release. The engagement of the screw 9 in the bore 11 creates an anti-loosening thread lock.
De préférence, les orifices 7 et 8 reçoivent la vis 9 avec un jeu 12 (visible aux figures 3 et 4) , ce qui autorise le retrait de la matière thermoplastique lors du refroidissement du corps de caniveau 2.Preferably, the orifices 7 and 8 receive the screw 9 with a clearance 12 (visible in FIGS. 3 and 4), which authorizes the withdrawal of the thermoplastic material during the cooling of the channel body 2.
La rainure 5 en V ménagée aux extrémités supérieures verticales des branches 2a du corps de caniveau 2 est pourvue en partie médiane, d'une saillie telle qu'une butée 13.The V-shaped groove 5 formed at the vertical upper ends of the branches 2a of the channel body 2 is provided in the middle part, with a projection such as a stop 13.
De manière à positionner la feuillure 3 sur l'extrémité supérieure d'une branche du corps de caniveau 2, ladite feuillure 3 présente une découpe 14 en partie médiane à travers laquelle peut être engagée avec jeu, la butée 13 de la rainure 5 en V du corps de caniveau 2.So as to position the rebate 3 on the upper end of a branch of the channel body 2, said rebate 3 has a cutout 14 in the middle part through which can be engaged with play, the stop 13 of the groove 5 in V channel body 2.
Ainsi pour réaliser un élément de caniveau 1 selon l'invention, on forme d'abord par injection le corps de caniveau 2 en matière thermoplastique de manière à ce que celui-ci présente à chacune des extrémités supérieures de ses branches 2a, sur la face verticale interne desdites branches 2a, une rainure 5 en V pourvue d'une butée 13 centrale.Thus, to produce a channel element 1 according to the invention, the channel body 2 made of thermoplastic material is first formed by injection so that it has at each of the upper ends of its branches 2a, on the face internal vertical of said branches 2a, a V-shaped groove 5 provided with a central stop 13.
Puis, à chaud en sortie de presse, on met en place, sur chaque extrémité supérieure de branche 2a du corps. ' de caniveau 2, une feuillure 3 pourvue d'une découpe 14 en partie médiane à travers laquelle la butée 13 du corps de caniveau 2 est engagée avec jeu.Then, when hot at the press outlet, one sets up, on each upper end of branch 2a of the body. ' of channel 2, a rabbet 3 provided with a cutout 14 in the middle part through which the stop 13 of the channel body 2 is engaged with play.
On installe ensuite la grille 4 qui est alors fixée à l'aide de vis 9 et d'écrous 10. L'engagement à chaud des vis 9 dans les alésages 11 ménagés respectivement dans le corps de caniveau 2 sous chaque écrou 10 et de diamètre inférieur au diamètre d'une vis 9 permet alors de recréer un frein filet anti-desserage .The grid 4 is then installed, which is then fixed using screws 9 and nuts 10. The hot engagement of the screws 9 in the bores 11 formed respectively in the channel body 2 under each nut 10 and of diameter less than the diameter of a screw 9 then makes it possible to recreate an anti-loosening thread lock.
Le jeu entre la découpe 14 de la feuillure 3 et la butée 13 du corps de caniveau 2 permet un retrait symétrique du corps de caniveau 2 de part et d'autre de ladite butée 13 de manière similaire au jeu 12 au niveau des orifices 7, 8 de la feuillure 3 et la grille . The clearance between the cutout 14 of the rebate 3 and the stop 13 of the channel body 2 allows a symmetrical withdrawal of the channel body 2 on either side of said stop 13 in a similar manner to the clearance 12 at the orifices 7, 8 of rebate 3 and the grid.
