A l'opposé du fond 108, la cuve structurelle 102 présente une ouverture 110.The structural vessel 102 is monobloc and monomatized and is in the form of a cylindrical vessel which has a side wall 106 and a bottom 108 which closes one end of the side wall 106 and which is intended to rest on the ground when placing the machined lens 200. In contrast to the bottom 108, the structural vessel 102 has an opening 110.

La cuve structurelle 102 constitue l'ossature du regard 100, 200 et comme la cuve structurelle 102 est constituée d'un seul élément, il n'y pas de risque de fuite. La cuve structurelle 102 est réalisée en béton qui est un matériau dur. La cuve structurelle 102 est réalisée par exemple par moulage.The structural vessel 102 constitutes the framework of the view 100, 200 and since the structural vessel 102 consists of a single element, there is no risk of leakage. The structural vessel 102 is made of concrete which is a hard material. The structural vessel 102 is made for example by molding.

Le béton est constitué d'un agglomérat de granulats agglomérés par un liant hydraté. Les granulats représentent 75% du volume du béton et sont constitués d'éléments de taille millimétrique tels que des grains de sable et d'éléments de taille centimétrique tels que des gravillons.Concrete consists of an agglomerate of aggregates agglomerated with a hydrated binder. Aggregates represent 75% of the concrete volume and consist of millimeter-sized elements such as grains of sand and centimeter-sized elements such as chippings.

La partie usinable 104 est monobloc et monomatière et, après séchage de la cuve structurelle 102, elle est coulée dans la cuve structurelle 102 par l'ouverture 110.The machinable portion 104 is monobloc and monomatized and, after drying of the structural vessel 102, it is poured into the structural vessel 102 through the opening 110.

Après coulage, la partie usinable 104 présente une face orientée vers l'ouverture 110 de la cuve structurelle 102. La face plane permettra ultérieurement de réaliser toutes les formes envisageables de cunettes 202 et de banquettes 204. La partie usinable 104 présente une hauteur suffisante à la réalisation des cunettes 202 et des banquettes 204.After casting, the machinable portion 104 has a face facing the opening 110 of the structural vessel 102. The planar face will subsequently make possible all possible forms of cunettes 202 and benches 204. The machinable portion 104 has a sufficient height to the realization of cunettes 202 and benches 204.

La partie usinable 104 constitue l'élément modifiable du regard 100, 200 et elle est réalisée en mortier qui est un matériau tendre.The machinable portion 104 constitutes the modifiable element of the look 100, 200 and is made of mortar which is a soft material.

Le mortier est également constitué d'un agglomérat de granulats agglomérés par un liant hydraté. Les granulats représentent 50% du volume du mortier et sont constitués uniquement d'éléments de taille millimétrique tels que des grains de sable. Le mortier présente l'avantage de pouvoir être facilement usiné plusieurs semaines après son coulage.The mortar also consists of an agglomerate of aggregates agglomerated with a hydrated binder. Aggregates represent 50% of the volume of the mortar and consist only of millimeter-sized elements such as grains of sand. The mortar has the advantage of being easily machined several weeks after pouring.

La face de la partie usinable 104 qui est orientée vers l'ouverture 110 peut être plane.The face of the machinable portion 104 which is oriented towards the opening 110 may be flat.

La Fig. 5 montre un regard brut 500 selon un deuxième mode de réalisation de l'invention et qui présente une structure bi-matière. Le regard brut 500 présente une cuve structurelle 102 et une partie usinable 504 qui est réalisée au fond de la cuve structurelle 102.The Fig. 5 shows a raw look 500 according to a second embodiment of the invention and which has a bi-material structure. The raw look 500 has a structural vessel 102 and a machinable portion 504 which is formed at the bottom of the structural vessel 102.

Le regard brut 500 du deuxième mode de réalisation de l'invention se distingue du regard brut 100 du premier mode de réalisation par la forme de leurs parties usinables 104, 504.The raw look 500 of the second embodiment of the invention differs from the raw look 100 of the first embodiment by the shape of their machinable portions 104, 504.

Dans ce mode de réalisation de l'invention, la face de la partie usinable 504 présente une forme en creux. C'est-à-dire que la face s'enfonce vers l'intérieur de la partie usinable 504 à partir de la paroi latérale 106. La face présente par exemple la forme d'un cône dont la grande base court le long de la paroi latérale 106 et dont le sommet 502 est orienté vers le fond 108. La hauteur de mortier est ainsi plus importante le long de la paroi latérale 106 qu'à distance de celle-ci.In this embodiment of the invention, the face of the machinable portion 504 has a hollow shape. That is to say that the face is sinking towards the inside of the machinable portion 504 from the side wall 106. The face has for example the shape of a cone whose large base runs along the side wall 106 and whose top 502 is oriented towards the bottom 108. The mortar height is thus greater along the side wall 106 at distance from it.

Cette forme particulière de la face permet de réduire le volume de la partie usinable 504 qui doit être usinée pour obtenir les cunettes 202 les banquette 204.This particular shape of the face makes it possible to reduce the volume of the machinable portion 504 which must be machined to obtain the cunettes 202 the bench 204.

Dans les deux modes de réalisation de l'invention, la face et la partie usinable 104, 504 sont creusées afin de former les cunettes 202 et les banquettes 204. Chaque cunette 202 présente une extrémité en contact avec la paroi latérale 106.In both embodiments of the invention, the face and the machinable portion 104, 504 are hollowed to form the cunettes 202 and the benches 204. Each cunette 202 has an end in contact with the side wall 106.

Pour faciliter le travail de la fraise (304, Fig. 3) qui usine les cunettes 202 et les banquettes 204, un trou 112, 512 traverse au moins en partie la partie usinable 104, 504. Le trou 112, 512 s'étend à partir de la face en direction du fond 108. La hauteur du trou 112, 512 est égale ou inférieure à la hauteur de la partie usinable 104, 504.To facilitate the work of the cutter (304, Fig. 3 ) which makes the cunettes 202 and the benches 204, a hole 112, 512 at least partially passes through the machinable portion 104, 504. The hole 112, 512 extends from the face towards the bottom 108. The height of the hole 112, 512 is equal to or less than the height of the machinable portion 104, 504.

La fraise 304 est alors insérée dans le trou 112, 512 et travaille en retirant de la matière de la partie usinable 104.The cutter 304 is then inserted into the hole 112, 512 and works by removing material from the machinable portion 104.

Le trou 112, 512 est réalisé par forage ou par la mise en place d'une empreinte lors de la réalisation de la partie usinable 104, 504 puis par retrait de cette empreinte.The hole 112, 512 is made by drilling or by placing an impression during the production of the machinable portion 104, 504 and then by removing this impression.

Le fait que le regard 100, 200, 500 soit constitué d'une partie en béton et d'une partie en mortier qui est la seule à être ultérieurement usinée permet de stocker des regards bruts 100 non usinés pendant plusieurs semaines.The fact that the look 100, 200, 500 is made of a concrete part and a mortar portion which is the only part to be subsequently machined makes it possible to store blanks 100 not machined for several weeks.

Ainsi, pour chaque commande d'un regard avec des cunettes 202 particulières, il est aisé de prélever un regard brut 100, 500 et de creuser les cunettes 202 voulues. Il est ainsi possible de réaliser simplement et rapidement toutes les formes possibles de cunettes 202 et de banquettes 204, afin de répondre à toutes les dispositions possibles de canalisations et ceci tout en réduisant le temps du cycle de production des regards usinés 200.Thus, for each command of a look with particular cunettes 202, it is easy to take a raw look 100, 500 and dig the cunettes 202 desired. It is thus possible to simply and quickly realize all possible forms of cunettes 202 and bench 204, to meet all the possible arrangements of pipes and this while reducing the production cycle time of machined mounts 200.

La Fig. 3 montre une étape d'usinage du regard brut 100 par un robot d'usinage 300 appartenant à un îlot d'usinage et la Fig. 4 montre la même étape selon une vue en coupe par un plan vertical.The Fig. 3 shows a step of machining the raw look 100 by a machining robot 300 belonging to a machining island and the Fig. 4 shows the same step in a sectional view by a vertical plane.

Selon un premier mode de réalisation particulier de l'invention, un procédé de fabrication du regard brut 100, 500 consiste en:

  • une étape de réalisation de la cuve structurelle 102 en béton,
  • une étape de séchage de la cuve structurelle 102 ainsi réalisée,
  • une étape de remplissage de la cuve structurelle 102 ainsi séchée par coulage de mortier afin de constituer la partie usinable 104, 504, et
  • une étape de séchage de la partie usinable 104, 504 ainsi coulée.
According to a first particular embodiment of the invention, a manufacturing method of the raw look 100, 500 consists of:
  • a step of producing the concrete structural vessel 102,
  • a drying step of the structural vessel 102 thus produced,
  • a step of filling the structural vessel 102 thus dried by casting mortar to form the machinable portion 104, 504, and
  • a step of drying the machinable portion 104, 504 thus cast.

L'étape de réalisation de la cuve structurelle 102 en béton s'effectue par exemple par moulage.The step of producing the concrete structural vessel 102 is carried out for example by molding.

Dans le cas où la face de la partie usinable 504 est en creux, l'étape de remplissage est suivie d'une étape de mise en place d'une empreinte adaptée à la forme de la face à obtenir avant l'étape de séchage de la partie usinable 504.In the case where the face of the machinable portion 504 is recessed, the filling step is followed by a step of placing an imprint adapted to the shape of the face to be obtained before the drying step of the machinable portion 504.

L'étape de séchage de la cuve structurelle 102 dure au moins deux jours. Cette durée pouvant varier selon le béton mis en oeuvre.The drying step of the structural vessel 102 lasts at least two days. This duration may vary depending on the concrete used.

Selon un deuxième mode de réalisation de l'invention, un procédé de fabrication d'un regard brut 100, 500 consiste réaliser simultanément la cuve structurelle 102 et la partie usinable 104, 504.According to a second embodiment of the invention, a manufacturing method of a raw look 100, 500 consists of simultaneously producing the structural vessel 102 and the machinable portion 104, 504.

La Fig. 6 montre un noyau 600 permettant la mise en oeuvre du procédé de fabrication selon le deuxième mode de réalisation de l'invention. La Fig. 6 montre le noyau 600 en position de moulage.The Fig. 6 shows a core 600 allowing the implementation of the manufacturing method according to the second embodiment of the invention. The Fig. 6 shows the core 600 in the molding position.

Le noyau 600 comporte une virole 604, un fond 606 et un moule 602.The core 600 has a shell 604, a bottom 606 and a mold 602.

La virole 604 est constituée d'un cylindre creux en tôle et le fond 606 est solidaire de la virole 604 et s'étend en travers de celle-ci et à distance des extrémités supérieures et inférieures de la virole 604.The ferrule 604 consists of a hollow sheet metal cylinder and the bottom 606 is integral with the ferrule 604 and extends therethrough and away from the upper and lower ends of the ferrule 604.

Le moule 602 est ici solidaire de la virole 604 et s'étend autour de celle-ci et à distance de celle-ci sauf au niveau de la jonction entre la virole 604 et le moule 602. Cette jonction se situe au-dessous du fond 606.The mold 602 is here secured to the ferrule 604 and extends around it and at a distance therefrom except at the junction between the ferrule 604 and the mold 602. This junction is located below the bottom 606.

Lorsque la partie usinable 504 est en creux et plus particulièrement en forme de cône, le fond 606 présente une forme adaptée et plus particulièrement en forme de cône dont le sommet est orienté vers le haut.When the machinable portion 504 is hollow and more particularly cone-shaped, the bottom 606 has a shape adapted and more particularly cone-shaped whose apex is oriented upwards.

Il est ainsi défini un premier volume 608 entre le fond 606 et les extrémités supérieures de la virole 604. Le premier volume 608 prend la forme de la partie usinable 104, 504.Thus, a first volume 608 is defined between the bottom 606 and the upper ends of the ferrule 604. The first volume 608 takes the form of the machinable portion 104, 504.

Il est également ainsi défini un deuxième volume 610 entre la virole 604 et le moule 602. Le deuxième volume 610 prend la forme de la cuve structurelle 102.A second volume 610 is thus defined between the ferrule 604 and the mold 602. The second volume 610 takes the form of the structural vessel 102.

Le procédé de fabrication consiste alors en:

  • une première étape de coulage du mortier constituant la partie usinable 104, 504 dans le premier volume 608,
  • une deuxième étape de coulage du béton constituant la cuve structurelle 102 dans le deuxième volume 610,
  • une étape de séchage du mortier et du béton ainsi coulés au cours de laquelle le mortier et le béton sont au moins partiellement séchés, et
  • une étape de retrait du regard brut 100, 500 ainsi réalisé par retrait du moule 602, de la virole 604 et du fond 606.
The manufacturing process then consists of:
  • a first casting step of the mortar constituting the machinable portion 104, 504 in the first volume 608,
  • a second casting step of the concrete constituting the structural vessel 102 in the second volume 610,
  • a step of drying the mortar and cast concrete during which the mortar and the concrete are at least partially dried, and
  • a step of withdrawal of the raw look 100, 500 thus achieved by withdrawal of the mold 602, the ferrule 604 and the bottom 606.

Ce procédé permet un gain de temps, puisque les étapes de séchage sont concomitantes.This method saves time since the drying steps are concomitant.

Le procédé de fabrication du regard usiné 200 consiste alors après l'étape de séchage de la partie usinable 104, 504 en une étape d'usinage de la partie usinable 104, 504 ainsi séchée à l'aide du robot d'usinage 300 pour réaliser les cunettes 202 et les banquettes 204.The method of manufacturing the machined lens 200 then consists of the step of drying the machinable portion 104, 504 in a machining step of the machinable portion 104, 504 and dried using the machining robot 300 to achieve cunettes 202 and benches 204.

Le robot d'usinage 300 comporte un bras 302 qui est orientable dans l'espace et une fraise 304 adaptée pour usiner le mortier et qui est d'un coût moins important qu'un outil pouvant usiner des matériaux plus durs tels que le béton.The machining robot 300 comprises an arm 302 which is steerable in space and a mill 304 adapted to machine the mortar and which is of a lower cost than a tool that can machine harder materials such as concrete.

Bien sûr, le robot d'usinage 300 peut comporter un magasin d'outils dans lequel plusieurs fraises 304 sont disponibles. Les fraises 304 présentent des caractéristiques différentes les unes des autres et peuvent être montées automatiquement sur le bras 302. La fraise 304 qui est montée est choisie par le robot d'usinage 300 en fonction de l'usinage à effectuer.Of course, the machining robot 300 may include a tool magazine in which a plurality of milling cutters 304 are available. The cutters 304 have different characteristics from each other and can be mounted automatically on the arm 302. The cutter 304 which is mounted is chosen by the machining robot 300 according to the machining to be performed.

Pour faciliter l'évacuation des débris dus à l'usinage, le regard brut 100 est disposé et maintenu de manière à ce que l'ouverture 110 se trouve dans un plan sensiblement vertical, c'est-à-dire telle qu'elle est représentée sur la Fig. 4, et un jet d'eau est dirigé vers les zones usinées. L'angle de positionnement du regard brut 100 lors de l'usinage peut varier de +/- 10°.To facilitate the evacuation of debris due to machining, the raw look 100 is arranged and held so that the opening 110 is in a substantially vertical plane, that is to say as it is represented on the Fig. 4 , and a jet of water is directed to the machined areas. The angle of positioning of the raw look 100 during the machining can vary by +/- 10 °.

L'inclinaison et l'écoulement d'eau permettent d'évacuer les débris.The inclination and the flow of water make it possible to evacuate the debris.

L'inclinaison de 90°±10° est suffisante pour évacuer les débris car ceux-ci sont extraits de la partie usinable 104, 504 qui est réalisée en mortier et produit donc des débris de petite taille facilement évacués par l'eau.The inclination of 90 ° ± 10 ° is sufficient to evacuate the debris because they are extracted from the machinable part 104, 504 which is made of mortar and therefore produces small debris easily removed by water.

Le maintien du regard brut 100 durant l'usinage est assuré par un dispositif de maintien par exemple du type comportant des mâchoires entre lesquelles est placé le regard brut 100.The maintenance of the raw look 100 during machining is provided by a holding device for example of the type having jaws between which is placed the raw eye 100.

La paroi latérale 106 du regard usiné 200 présente également pour chaque extrémité d'une cunette 202, un orifice destiné à être connecté à une canalisation et aligné avec ladite extrémité. Pour assurer le bon positionnement de chaque orifice avec l'extrémité associée, l'îlot d'usinage comporte également des moyens pour repérer et marquer les positions de ces orifices.The side wall 106 of the machined lens 200 also has for each end of a casette 202, an orifice intended to be connected to a pipe and aligned with said end. To ensure the proper positioning of each orifice with the associated end, the machining island also comprises means for identifying and marking the positions of these orifices.

Le procédé de fabrication comporte alors pour chaque extrémité d'une cunette 202, une étape de repérage et de marquage, sur la surface extérieure de la paroi latérale 106, d'une position alignée avec ladite extrémité et une étape de perçage d'un orifice à cette position ainsi repérée et marquée.The manufacturing method then comprises for each end of a cunette 202, a marking and marking step, on the outer surface of the side wall 106, of a position aligned with said end and a step of drilling an orifice. at this position so marked and marked.

Le repérage est assuré du fait que le robot d'usinage 300 comporte une unité de traitement qui connaît la géométrie du regard brut 100, la position des extrémités de chaque cunette 202 et donc, pour chaque extrémité, la position de l'orifice qui devra être percé et aligné avec ladite extrémité.The identification is ensured by the fact that the machining robot 300 comprises a processing unit which knows the geometry of the raw look 100, the position of the ends of each cunette 202 and therefore, for each end, the position of the orifice which will have to be pierced and aligned with said end.

Le marquage est assuré par exemple par la dépose d'un élément visuel, tel que des points de couleur sur la surface extérieure de la paroi latérale 106.The marking is ensured for example by the removal of a visual element, such as colored dots on the outer surface of the side wall 106.

Le perçage des orifices est alors réalisé grâce à des outils de carottage qui se positionnent en fonction des éléments de marquage. Chaque orifice est ainsi aligné avec une extrémité d'une cunette 202.The drilling of the orifices is then achieved through coring tools which are positioned according to the marking elements. Each orifice is thus aligned with one end of a cunette 202.

Bien entendu, la présente invention n'est pas limitée aux exemples et modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art.Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of many variants accessible to those skilled in the art.
