Description

La présente invention concerne généralement le domaine de la collecte et l'évacuation des eaux de pluie, plus particulièrement la réception des eaux de pluie en sortie de tuyau débouchant d'un toit plat d'un bâtiment. Plus précisément, la présente invention concerne une boîte à eau destinée à être fixée sur la façade d'un bâtiment.The present invention generally relates to the field of collecting and evacuating rainwater, more particularly the reception of rainwater at the outlet of pipe emerging from a flat roof of a building. More specifically, the present invention relates to a water box intended to be fixed on the facade of a building.

Etat de la techniqueState of the art

Afin de faciliter l'évacuation d'eaux de pluie d'un toit plat entouré par un acrotère, des boîtes à eaux ont été développées, pour réceptionner les eaux en sortie de traversée d'acrotère. Un tuyau traversant l'acrotère débouche dans la boîte et les eaux de pluie sont redirigées vers un descendant vertical.In order to facilitate the evacuation of rainwater from a flat roof surrounded by a parapet, water boxes have been developed to receive water at the end of acroterion crossing. A pipe crossing the acroterium leads into the box and the rainwater is redirected to a vertical descendant.

Le document JP2008274717 montre une boîte à eau ouverte vers le haut, avec une entrée de la traversée d'acrotère et une sortie vers le tube de descente de forme cylindrique simple. D'autres exemples de boîtes à eau sont décrits dans les documents JP2008180040 , JP2007002616 et JP2008180043 , dans lesquels les boîtes à eau présentent une paroi arrière sensiblement une forme en « U » pour faciliter le montage à la façade. Parallèlement, les boîtes à eau apportent une dissimulation de la traversée d'acrotère pour une meilleure intégration esthétique dans la façade du bâtiment. Les documents JP 2008 133615 et JP 2009 052317 divulguent une boîte à eau selon le préambule de la revendication 1.The document JP2008274717 shows an upward open water box, with an entrance to the parapet traverse and an outlet to the single cylindrical downcomer. Other examples of water boxes are described in the documents JP2008180040 , JP2007002616 and JP2008180043 , in which the water boxes have a substantially U-shaped back wall to facilitate mounting to the facade. At the same time, the water boxes provide a concealment of the parapet traverse for a better aesthetic integration in the facade of the building. The documents JP 2008 133615 and JP 2009 052317 disclose a water box according to the preamble of claim 1.

La présente invention a pour but d'améliorer les performances hydrauliques des boîtes à eau.The present invention aims to improve the hydraulic performance of water boxes.

Résumé de l'inventionSummary of the invention

La présente invention propose une boîte à eau selon la revendication 1. La boîte à eau est destinée à être fixée sur un côté extérieur d'une paroi entourant une surface sensiblement horizontale d'un bâtiment telle un acrotère comprenant un corps de réservoir pour la réception d'un flux d'eau, le corps de réservoir comprenant un fond, une paroi arrière pour la fixation sur un côté extérieur d'un acrotère, et au moins une paroi latérale, et une sortie vers un descendant avec un axe longitudinal de sortie. Un dispositif de réorientation de flux d'eau est positionné dans le corps de réservoir, et est destiné à intercepter partiellement le flux d'eau dans le corps de réservoir et à l'orienter vers la sortie. Le dispositif de réorientation comprend un réceptacle positionné dans le corps de réservoir, le réceptacle comprenant un corps supérieur, le corps supérieur étant orienté selon un axe de réservoir principal. L'axe de réservoir est décalé de l'axe de la sortie, l'axe de réservoir étant sensiblement vertical lorsque la boite à eau est fixée en position fonctionnelleThe present invention provides a water box according to claim 1. The water box is intended to be fixed on an outer side of a wall surrounding a substantially horizontal surface of a building such as an acroterium comprising a tank body for receiving a stream of water, the tank body comprising a bottom, a rear wall for attachment to an outer side of a parapet, and at least one side wall, and an outlet to a descendant with a longitudinal output axis. A water flow reorientation device is positioned in the tank body, and is intended to partially intercept the flow of water in the tank body and to direct it towards the outlet. The redirecting device comprises a receptacle positioned in the reservoir body, the receptacle including an upper body, the upper body being oriented along a main reservoir axis. The reservoir axis is offset from the axis of the outlet, the reservoir axis being substantially vertical when the water box is fixed in the operative position

Ainsi la présente invention propose un dispositif de réorientation de flux d'eau, adapté pour intercepter le flux d'eau en sortie d'acrotère, sensiblement horizontal, afin de réorienter, au plus tôt dans sa chute, le flux d'eau vers la sortie verticale. La réorientation des trajectoires de l'eau améliore significativement son entonnement dans le moignon vertical, et les performances hydrauliques de l'ensemble. La plupart du temps, il va s'agir d'eau de pluie mais il peut tout aussi bien s'agir d'eau résultant d'un nettoyage ou d'un arrosage exagéré etc.Thus, the present invention proposes a device for redirecting the flow of water, adapted to intercept the flow of water at the outlet of a paratrooper, which is substantially horizontal, in order to redirect, as soon as it falls, the flow of water towards the water. vertical exit. The reorientation of the trajectories of the water significantly improves its entonnement in the vertical stump, and the hydraulic performances of the whole. Most of the time, it will be rain water but it may also be water resulting from excessive cleaning or watering etc.

Le réceptacle est prévu pour intercepter le flux d'eau en sortie d'acrotère et créer un chemin de circulation d'eau pour orienter le flux d'eau vers la sortie. Un réceptacle, de préférence choisi à hauteur sensiblement équivalente au fil d'eau de la traversée d'acrotère, permet d'intercepter le flux d'eau et de définir un chemin d'écoulement préférentiel vers la sortie, pouvant idéalement aussi induire un effet vortex optionnel.The receptacle is designed to intercept the water flow at the acroterion outlet and create a water circulation path to direct the flow of water to the outlet. A receptacle, preferably chosen at a height substantially equivalent to the water thread of the acroterion crossing, makes it possible to intercept the flow of water and to define a preferential flow path towards the outlet, which can also ideally induce an effect optional vortex.

En prévoyant un décalage des axes de réservoir principal et de sortie, on peut prévoir un chemin d'orientation de flux, pour orienter le flux intercepté vers la sortie verticale.By providing for a shift of the main reservoir and output axes, a flow orientation path can be provided to direct the intercepted flow to the vertical exit.

Selon un mode de réalisation de l'invention, le réceptacle comprend une base, dans le prolongement du corps supérieur, la base comprenant un pan incliné, afin de rediriger le flux d'eau selon l'axe. De préférence, la base se prolonge au-delà du fond. Avantageusement, le réceptacle est ainsi adapté pour détourner, à sa base, la lame d'eau qui circule au fond, de l'avant vers l'arrière. En prolongeant la base au-delà du fond, cela permet également de diviser la lame d'eau qui circule au fond en deux, engendrant un appel d'eau et augmentant ainsi la vitesse de circulation d'eau.According to one embodiment of the invention, the receptacle comprises a base, in the extension of the upper body, the base comprising an inclined pan, in order to redirect the flow of water along the axis. Preferably, the base extends beyond the bottom. Advantageously, the receptacle is thus adapted to divert, at its base, the blade of water flowing at the bottom, from front to rear. By extending the base beyond the bottom, it also divides the water slide that flows in the bottom in two, generating a call for water and increasing the speed of water circulation.

Dans un mode de réalisation, la paroi arrière est destinée à être fixée à une façade la paroi arrière comprenant un opercule. De préférence, l'opercule a une forme en " U ". En prévoyant une forme de U, la sortie de l'acrotère peut être intégrée dans la paroi arrière de la boîte à eau, ce qui améliore l'esthétique de l'ensemble.In one embodiment, the rear wall is intended to be fixed to a facade the rear wall comprising a lid. Preferably, the cap has a "U" shape. By providing a U shape, the exit of the acroterion can be integrated in the rear wall of the water box, which improves the aesthetics of the whole.

Dans un mode de réalisation, le corps de réservoir est muni d'un trop-plein d'alerte pour l'écoulement d'un filet d'eau en cas de saturation de la boîte à eau. De préférence, le corps supérieur de réceptacle sert comme trop-plein en cas de saturation de la boîte à eau.In one embodiment, the tank body is provided with an overflow warning for the flow of a trickle of water in case of saturation of the water box. Preferably, the upper container body serves as an overflow in case of saturation of the water box.

Selon l'invention, une cloison est disposée dans le corps de réservoir entre le corps supérieur de réceptacle et la paroi arrière. La cloison est disposée perpendiculairement à la paroi arrière. Une telle cloison permet d'améliorer l'efficacité hydraulique en évitant que deux flux d'eau qui arrivent sur l'arrière se percutent frontalement et se gênent pour l'entonnement.According to the invention, a partition is disposed in the reservoir body between the upper receptacle body and the rear wall. The partition is arranged perpendicularly to the rear wall. Such a partition makes it possible to improve the hydraulic efficiency by avoiding that two streams of water that arrive on the rear collide head-on and interfere with the sounding.

La présente invention propose une boîte à eau avec un dispositif de réorientation de flux d'eau assurant une optimisation de l'entonnement de l'eau dans le descendant vertical.The present invention provides a water box with a water flow reorientation device ensuring optimization of the water intonation in the vertical descendant.

Sur les figures, des éléments identiques sont indiqués par des numéros de référence identiques.In the figures, identical elements are indicated by identical reference numbers.

Les figures 1 à 5 montrent une boîte à eau 1 selon un aspect de la présente invention destinée à être montée sur une façade 100 d'un bâtiment. La boîte à eau 1 est positionnée sensiblement au droit de la traversée d'acrotère 4 d'un toit plat 101, pour la réception des eaux de pluie en sortie d'acrotère débouchant du toit plat d'un bâtiment.The Figures 1 to 5 show a water box 1 according to an aspect of the present invention to be mounted on a facade 100 of a building. The water box 1 is positioned substantially to the right of the parapet traverse 4 of a flat roof 101, for the reception of rainwater acroterion outlet opening from the flat roof of a building.

La boîte à eau 1 comprend un corps de réservoir 5 pour la réception des eaux de pluie, avec une entrée 6 pour la traversée 4 d'acrotère et une sortie 7 vers un descendant 8 orienté selon un axe X sensiblement vertical lorsque la boîte à eau est montée à la façade 100.The water box 1 comprises a tank body 5 for the reception of rainwater, with an inlet 6 for the acroterion crossing 4 and an outlet 7 to a descendant 8 oriented along a substantially vertical axis X when the water box is mounted to the facade 100.

Le corps de réservoir 5 comprend un fond 50 débouchant sur la sortie 7 vers le descendant, une paroi latérale 52 et une paroi arrière 55 destinée à venir en appui contre la façade.The tank body 5 comprises a bottom 50 opening on the outlet 7 to the descendant, a side wall 52 and a rear wall 55 intended to bear against the facade.

Dans le mode de réalisation représenté, le corps de réservoir 5 est sensiblement parallélépipédique, la paroi arrière 55 et la paroi latérale 52 formant un ensemble de type cubique. Bien entendu d'autres formes sont envisageables, le corps de réservoir peut être par exemple de forme cylindrique, avec la paroi arrière 55 étant une paroi de forme sensiblement plane pour venir en appui contre la façade et la paroi latérale 52 de forme incurvée.In the embodiment shown, the tank body 5 is substantially parallelepipedal, the rear wall 55 and the side wall 52 forming a cubic type assembly. Of course other forms are conceivable, the tank body may be for example of cylindrical shape, with the rear wall 55 being a substantially flat wall to bear against the front and the side wall 52 of curved shape.

Des moyens de fixation de la boîte à eau à la façade sont prévus. Comme bien vu sur les figures 2 à 4, la paroi arrière 55 comprend au moins une oreille ou patte de fixation 16. La au moins une oreille 16 peut être découpable, et comprend un ou plusieurs trous de fixation 17, permettant le passage d'une vis de fixation. De préférence, deux oreilles munies de deux trous oblongues sont prévues.Means for fixing the water box to the facade are provided. As seen on the Figures 2 to 4 , the rear wall 55 comprises at least one ear or lug 16. The at least one lug 16 can be cut, and comprises one or more mounting holes 17, allowing the passage of a fixing screw. Preferably, two ears provided with two oblong holes are provided.

La paroi arrière 55 est munie d'un opercule 56 afin de former l'entrée 6 pour intégrer la traversée d'acrotère à l'arrière de celle-ci, pour des raisons à la fois esthétiques et hydrauliques. De préférence, l'entrée 6 est en forme de U. Dans le mode de réalisation ainsi représenté, l'entrée 6 pour la traversée d'acrotère est intégrée dans la paroi arrière 55. Bien entendu, cet exemple n'est pas limitatif et, dans certaines applications, la traversée d'acrotère peut déboucher au dessus de la paroi arrière.The rear wall 55 is provided with a cover 56 to form the inlet 6 to integrate the acroterion crossing at the rear thereof, for both aesthetic and hydraulic reasons. Preferably, the inlet 6 is U-shaped. In the embodiment as well shown, the entry 6 for the parapet traverse is integrated in the rear wall 55. Of course, this example is not limiting and, in some applications, the acroterial crossing may lead to the top of the rear wall.

Un dispositif de réorientation de flux d'eau 11 est positionné à l'intérieur du corps de réservoir 5, pour intercepter partiellement le flux d'eau en sortie d'acrotère, qui est sensiblement horizontal, et l'orienter dans la sortie 7 et le descendant 8, sensiblement vertical lorsque la boîte est en position fonctionnelle. Dans le mode de réalisation représenté, le dispositif de réorientation de flux d'eau comprend un réceptacle 11, prévu pour avoir une hauteur sensiblement équivalente au fil d'eau de la traversée d'acrotère.A water flow reorientation device 11 is positioned inside the tank body 5, to partially intercept the water flow at the acroterion outlet, which is substantially horizontal, and to orient it in the outlet 7 and the descendant 8, substantially vertical when the box is in the operative position. In the embodiment shown, the water flow reorientation device comprises a receptacle 11, designed to have a height substantially equivalent to the water thread of the parapet traverse.

Le réceptacle 11 comprend un corps supérieur de réceptacle 30 sensiblement perpendiculaire au fond 50 et une base 40, dans le prolongement du corps supérieur de réceptacle 30, et qui dépasse du fond 50 et se prolonge et forme la sortie 7. Le réceptacle 11 est orienté sensiblement verticalement lorsque la boîte à eau est fixée sur la façade, avec la sortie 7 de la base 40 se prolongeant à l'intérieur de l'emboîture du descendant 8, lorsque la boîte à eau est en position fonctionnelle.The receptacle 11 comprises an upper receptacle body 30 substantially perpendicular to the bottom 50 and a base 40, in the extension of the upper receptacle body 30, and protruding from the bottom 50 and extends and forms the outlet 7. The receptacle 11 is oriented substantially vertically when the water box is fixed on the facade, with the outlet 7 of the base 40 extending inside the socket of the descendant 8, when the water box is in the operative position.

Le corps supérieur de réceptacle 30 est sensiblement cylindrique, avec une face arrière 35 côté paroi arrière 55 et une face avant 32 opposée à la face arrière. Le corps supérieur de réceptacle est orienté selon un axe longitudinal de réservoir principal R sensiblement vertical lorsque la boîte à eau est fixée à la façade. L'axe de réservoir R est décalé de l'axe X de la sortie 7.The upper receptacle body 30 is substantially cylindrical, with a rear wall side rear face 55 and a front face 32 opposite to the rear face. The upper receptacle body is oriented along a substantially vertical main reservoir axis R substantially when the water box is attached to the facade. The tank axis R is offset from the X axis of the outlet 7.

La base 40 comprend une paroi inclinée 42, selon une inclinaison vers la paroi arrière 55, faisant la transition entre la face avant 32 du corps supérieur de réceptacle 30, sensiblement vertical en position fonctionnelle, et la sortie 7 vers le descendant. Ainsi, le corps supérieur de réceptacle 30, en particulier la face avant 32 du corps cylindrique du réceptacle 11, opère un effet de barrage et détourne la lame d'eau circulant en fond de boîte. Le réceptacle cylindrique est ainsi adapté pour détourner, à sa base 40, la lame d'eau qui circule au fond, de l'avant vers l'arrière, et perturbe l'entonnement de l'eau dans le moignon cylindrique.The base 40 comprises an inclined wall 42, inclined towards the rear wall 55, making the transition between the front face 32 of the upper receptacle body 30, substantially vertical in the operative position, and the outlet 7 towards the descendant. Thus, the upper receptacle body 30, in particular the front face 32 of the cylindrical body of the receptacle 11, operates a damming effect and diverts the leaf of water circulating at the bottom of the box. The cylindrical receptacle is thus adapted to divert, at its base 40, the blade of water flowing at the bottom, from the front to the rear, and disturbs the sound of the water in the cylindrical stump.

La réorientation des trajectoires de l'eau améliore significativement son entonnement dans le moignon vertical, et les performances hydrauliques de l'ensemble. De plus, la base 40 du cylindre est prévue pour se prolonger à l'intérieur de l'emboîture du descendant, la divisant en deux, ce qui engendre un appel d'eau entre deux flux et augmente la vitesse de circulation d'eau.The reorientation of the trajectories of the water significantly improves its entonnement in the vertical stump, and the hydraulic performances of the whole. In addition, the base 40 of the cylinder is provided to extend inside the socket of the descendant, dividing it in two, which generates a call for water between two flows and increases the speed of water flow.

Une cloison 95, agencée dans le corps de réservoir entre le dispositif de réorientation de flux d'eau 30 et la paroi arrière 55 de la boîte à eau, évite que les deux flux d'eau qui arrivent sur l'arrière se percutent frontalement et se gênent pour l'entonnement. Ainsi, la cloison 95 dans le corps de réservoir participe également à l'efficacité hydraulique de la boîte à eau.A partition 95, arranged in the reservoir body between the water flow reorientation device 30 and the rear wall 55 of the water box, prevents the two streams of water that arrive on the rear from hitting the front and embarrass themselves for the sounding. Thus, the partition 95 in the tank body also contributes to the hydraulic efficiency of the water box.

Dans une forme de réalisation, la boîte à eau 1 comprend également un trop-plein d'alerte 15 prévu pour matérialiser l'écoulement d'un filet d'eau dans un angle arrière en cas de saturation, par bouchage ou obstruction par exemple, de la boîte à eau 1.In one embodiment, the water box 1 also comprises a warning overflow 15 provided for materializing the flow of a trickle of water in a rear angle in the event of saturation, by plugging or obstruction for example, of the water box 1.

Le trop-plein d'alerte 15 est prévu pour servir d'alerte visuelle, et le réceptacle 30 sert de trop-plein en cas de mise en charge de la boîte à eau. La hauteur de l'arête supérieure du réceptacle 30 est inférieure à la hauteur de l'opercule en « U ». Ainsi, si la sortie 7 est obstruée, par exemple par des feuilles, l'eau monte en charge et l'eau va passer dans le réceptacle 30 par débordement.The warning overflow 15 is intended to serve as a visual alert, and the receptacle 30 serves as overflow when charging the water box. The height of the upper edge of the receptacle 30 is less than the height of the lid "U". Thus, if the outlet 7 is obstructed, for example by leaves, the water rises in charge and the water will pass into the receptacle 30 by overflow.

La boîte à eau 1 est de préférence monobloc, avec une ouverture sur la partie supérieure.The water box 1 is preferably monobloc, with an opening on the upper part.

Une boîte monobloc présente l'avantage d'être simple à fabriquer et à installer, une seule pièce étant à fixer au niveau d'une façade, pour avoir une boîte à eau opérationnelle. De plus, contrairement aux dispositifs antérieurs dans lesquels la paroi arrière de la boite à eau a pour seule fonction la fixation à une remontée d'acrotère, la paroi arrière 55 de la boîte à eau 1 participe également à la délimitation du réceptacle 30, c'est-à-dire à la réorientation du flux.A monobloc box has the advantage of being simple to manufacture and install, one piece to be fixed at a facade, to have a water box operational. In addition, unlike prior devices in which the rear wall of the water box has the sole function of fixing to a rise acroterion, the rear wall 55 of the water box 1 also participates in the delimitation of the receptacle 30, c that is, the reorientation of the flow.

Ainsi, la structure monobloc et l'agencement de la boîte à eau selon l'invention permettent de s'affranchir de pièces additionnelles du type coude de réorientation d'eau réorientant le flux d'arrivée d'eau horizontal en entrée en un flux vertical en sortie de coude.Thus, the one-piece structure and the arrangement of the water box according to the invention make it possible to dispense with additional pieces of the water reorientation bend type redirecting the incoming horizontal water flow into a vertical flow. at the end of the elbow.

En somme, il reste à constater que la présente invention propose une boîte à eau pour la collecte des eaux de pluie d'un toit plat et l'évacuation vers une descente de gouttière en façade. Un réceptacle permet d'intercepter partiellement le flux d'eau et l'orienter dans le descendant afin d'améliorer l'évacuation des eaux de pluie. Le réceptacle permet également de limiter les perturbations hydrauliques et d'accélérer l'entonnement de l'eau.In sum, it remains to be noted that the present invention provides a water box for collecting rainwater from a flat roof and evacuation to a gutter down the front. A receptacle makes it possible to partially intercept the flow of water and to direct it downhill to improve the drainage of rainwater. The receptacle also makes it possible to limit the hydraulic disturbances and to speed up the sounding of the water.
