Généralement, les dalles plates de toits et les terrasses présentent des trous d'écoulement de l'eau de pluie qui est dirigée vers un réseau d'évacuation par des canalisations.Generally, the flat slabs of roofs and terraces have holes for the flow of rainwater which is directed towards a drainage network by pipes.

En particulier pour éviter que le réseau d'évacuation ne soit engorgé et ne déborde, il est connu d'équiper les toits et les terrasses de dispositifs de drainage en saillie qui entourent les trous d'écoulement et qui présentent des passages de sorte que le débit de l'eau évacuée soit limité.In particular, to prevent the drainage network from becoming clogged and overflowing, it is known to equip roofs and terraces with projecting drainage devices which surround the drainage holes and which have passages so that the flow rate of discharged water is limited.

Le brevet DE 1 806 527 décrit un dispositif de drainage qui comprend une couronne inférieure en appui sur un toit autour d'un trou d'évacuation et une couronne supérieure qui montée au-dessus de la couronne inférieure et sur laquelle est monté un cylindre vertical perforé en saillie par rapport au toit. L'eau traverse les perforations et, lorsque le niveau de l'eau atteint le bord supérieur du cylindre vertical perforé, l'eau se déverse, pour être dirigée vers le trou d'évacuation. Le dispositif de drainage comprend un capot perforé entourant à distance le cylindre perforé et monté sur la couronne supérieure. Le dispositif de drainage est muni d'une membrane d'étanchéité qui présente un passage dont le bord est pincé entre la couronne inférieure et la couronne supérieure et qui s'étend sur le toit, de sorte que le dispositif de drainage est intégré à l'étanchéité du toit.The patent OF 1 806 527 describes a drainage device which comprises a lower crown resting on a roof around a drainage hole and an upper crown which is mounted above the lower crown and on which is mounted a perforated vertical cylinder projecting with respect to the roof. The water passes through the perforations and, when the water level reaches the upper edge of the perforated vertical cylinder, the water spills out, to be directed to the drainage hole. The drainage device comprises a perforated cover remotely surrounding the perforated cylinder and mounted on the upper crown. The drainage device is provided with a waterproofing membrane which has a passage whose edge is pinched between the lower crown and the upper crown and which extends over the roof, so that the drainage device is integrated into the roof. roof sealing.

Selon un exemple de réalisation illustré sur les figures 1 à 6, un dispositif de drainage 1 est destiné à être installé sur une construction 2 qui comprend une paroi horizontale 3, dans le but d'évacuer l'eau se trouvant au-dessus de cette paroi horizontale 3.According to an exemplary embodiment illustrated in the figures 1 to 6 , a drainage device 1 is intended to be installed on a construction 2 which comprises a horizontal wall 3, in order to evacuate the water located above this horizontal wall 3.

La paroi horizontale 3 de la construction 2 comprend une dalle 4 qui présente un trou vertical 5 et comprend un recouvrement d'étanchéité 6 au-dessus de la dalle 4. Un conduit vertical d'évacuation 7 est disposé au travers du trou vertical 5. L'extrémité supérieure du conduit d'évacuation 7 est reliée au recouvrement d'étanchéité 6 par l'intermédiaire d'une membrane 8.The horizontal wall 3 of the construction 2 comprises a slab 4 which has a vertical hole 5 and includes a sealing cover 6 above the slab 4. A vertical evacuation duct 7 is placed through the vertical hole 5. The upper end of the evacuation duct 7 is connected to the sealing cover 6 via a membrane 8.

Ainsi, la paroi horizontale 3 de la construction 2 présente une surface extérieure horizontale 9 et est pourvue d'un canal vertical d'évacuation 10 délimité, par exemple, par le conduit vertical 7, pour l'évacuation de l'eau de pluie s'accumulant au-dessus de la surface extérieure horizontale 9.Thus, the horizontal wall 3 of the construction 2 has a horizontal outer surface 9 and is provided with a vertical evacuation channel 10 delimited, for example, by the vertical conduit 7, for the evacuation of rainwater s accumulating above the horizontal outer surface 9.

Le dispositif de drainage 1 comprend une tête de drainage 11 qui comprend une paroi extérieure 12 qui délimite un espace interne de récupération 13 destiné à communiquer avec l'extérieur et avec le canal d'évacuation 10. La paroi extérieure 12 est par exemple issue d'une tôle métallique.The drainage device 1 comprises a drainage head 11 which comprises an outer wall 12 which delimits an internal recovery space 13 intended to communicate with the outside and with the evacuation channel 10. The outer wall 12 for example comes from a sheet metal.

Plus spécifiquement, la paroi extérieure 12 présente un passage inférieur d'évacuation 14 autour duquel est aménagé un épaulement d'appui 15 destiné à prendre appui au-dessus de la surface extérieure 9 de la paroi horizontale 3 de la construction 2, autour du canal d'évacuation 8. La paroi extérieure 12 de la tête de drainage 11 s'étend vers le haut depuis la paroi horizontale 3 et l'espace interne de récupération 13 est au-dessus de l'embouchure du canal d'évacuation 10.More specifically, the outer wall 12 has a lower evacuation passage 14 around which is arranged a bearing shoulder 15 intended to bear above the outer surface 9 of the horizontal wall 3 of the construction 2, around the channel drain 8. The outer wall 12 of the drain head 11 extends upward from the horizontal wall 3 and the internal space of recovery 13 is above the mouth of the evacuation channel 10.

La paroi extérieure 12 de la tête de drainage 11 présente au moins un passage de récupération de l'eau, destiné à laisser entrer l'eau, qui se trouve sur la surface 9 de la paroi horizontale 3 de la construction 2 autour de la paroi extérieure 12, dans l'espace de récupération 13, de sorte que l'eau soit évacuée par le canal d'évacuation 10 depuis l'espace de récupération 13.The outer wall 12 of the drainage head 11 has at least one water recovery passage, intended to let in the water, which is on the surface 9 of the horizontal wall 3 of the construction 2 around the wall outside 12, in the recovery space 13, so that the water is evacuated through the evacuation channel 10 from the recovery space 13.

Avantageusement, la paroi extérieure 12 présente un passage inférieur calibré de récupération 16 (Figures 1 et 7) et un passage supérieur de récupération par déversement 17, qui peuvent être formés par des découpes de la paroi extérieure 12. Le passage inférieur de récupération 16 et le passage supérieur de récupération 17 sont décalés verticalement. Néanmoins, le passage inférieur de récupération 16 et le passage supérieur de récupération 17 pourraient communiquer.Advantageously, the outer wall 12 has a lower calibrated recovery passage 16 ( Figures 1 And 7 ) and an upper spill recovery passage 17, which may be formed by cutouts in the outer wall 12. The lower recovery passage 16 and the upper recovery passage 17 are offset vertically. Nevertheless, the lower recovery passage 16 and the upper recovery passage 17 could communicate.

Selon l'exemple illustré sur le dessin, la paroi extérieure 10 se présente sous la forme d'une cloche et comprend, selon un axe vertical, une portion inférieure cylindrique 18 dont le bord inférieur est pourvu, à l'intérieur, de l'épaulement d'appui 15, qui est annulaire, et une portion supérieure 19 renflée puis rétrécie, l'extrémité rétrécie étant pourvue d'une portion supérieure de jonction 20.According to the example illustrated in the drawing, the outer wall 10 is in the form of a bell and comprises, along a vertical axis, a cylindrical lower portion 18 whose lower edge is provided, on the inside, with the bearing shoulder 15, which is annular, and an upper portion 19 bulging then narrowed, the narrowed end being provided with an upper junction portion 20.

Le passage inférieur calibré de récupération 16 est prévu au travers de la portion inférieure 18, depuis l'épaulement d'appui 15, et est formé par exemple par deux ouvertures opposées, et le passage supérieur de récupération par déversement 17 est prévu au travers de la portion supérieure 19 et est formé par exemple par deux grandes ouvertures opposées.The lower calibrated recovery passage 16 is provided through the lower portion 18, from the bearing shoulder 15, and is formed for example by two opposite openings, and the upper spill recovery passage 17 is provided through the upper portion 19 and is formed for example by two large opposite openings.

Optionnellement, la tête de drainage 11 comprend un conduit inférieur d'extrémité 21 qui s'étend depuis le bord intérieur de l'épaulement d'appui 15 et qui est destiné à être engagé dans le canal d'évacuation 10.Optionally, the drainage head 11 comprises a lower end duct 21 which extends from the inner edge of the bearing shoulder 15 and which is intended to be engaged in the evacuation channel 10.

Lorsque la tête de drainage 11 est installée sur la paroi horizontale 3, le conduit d'extrémité 21 est engagé dans le canal d'évacuation 10 et l'épaulement d'appui 15 est en appui au-dessus de la paroi horizontale 3 de la construction 2, autour du canal d'évacuation 10.When the drainage head 11 is installed on the horizontal wall 3, the end duct 21 is engaged in the evacuation channel 10 and the support shoulder 15 is resting above the horizontal wall 3 of building 2, around the evacuation channel 10.

L'eau de pluie se trouvant sur la paroi horizontale 3 de la construction 2, autour de la paroi extérieure 12 de la tête de drainage 11, peut alors être évacuée de la manière suivante.The rainwater lying on the horizontal wall 3 of the construction 2, around the outer wall 12 of the drainage head 11, can then be evacuated in the following way.

L'eau de pluie s'écoule au travers du passage inférieur calibré de récupération 16 vers l'espace de récupération 13 délimité par la tête de drainage 11 puis s'écoule depuis l'espace de récupération 13 au travers du passage inférieur d'évacuation 14 et du conduit d'extrémité 21 vers le canal vertical d'évacuation 8.The rainwater flows through the lower calibrated recovery passage 16 towards the recovery space 13 delimited by the drainage head 11 then flows from the recovery space 13 through the lower evacuation passage 14 and from the end duct 21 to the vertical evacuation channel 8.

Lorsque le débit de l'eau au travers du passage inférieur calibré de récupération 16 est insuffisant, le niveau de l'eau monte puis atteint le passage supérieur de récupération 15 qui assure le déversement de l'eau dans l'espace de récupération 11 puis l'évacuation par le canal d'évacuation 10, à un débit plus grand que celui qui est possible par le passage calibré de récupération 16.When the water flow through the lower calibrated recovery passage 16 is insufficient, the water level rises and then reaches the upper recovery passage 15 which ensures the discharge of water into the recovery space 11 then evacuation through the evacuation channel 10, at a higher flow rate than that which is possible through the calibrated recovery passage 16.

Le dispositif de drainage 1 comprend un moyen de montage 22 destiné au maintien de la tête de drainage 11 en position installée.Drainage device 1 includes mounting means 22 for holding drainage head 11 in the installed position.

Le moyen de montage 22 comprend un moyen d'appui ou d'accrochage 23 apte à être engagé à l'intérieur du canal d'évacuation 10 formé par le conduit vertical 7 et un moyen de sollicitation 24 qui relie la tête de drainage 11 et le moyen d'appui ou d'accrochage 23 et est apte à agir sur le moyen d'appui ou d'accrochage 23. Le moyen d'appui ou d'accrochage 23 et le moyen de sollicitation 24 sont adaptés pour laisser passer l'eau comme décrit précédemment.The mounting means 22 comprises a support or hooking means 23 capable of being engaged inside the evacuation channel 10 formed by the vertical conduit 7 and a biasing means 24 which connects the drainage head 11 and the support or attachment means 23 and is able to act on the support or attachment means 23. The support or attachment means 23 and the biasing means 24 are adapted to let the water as previously described.

En position installée, le moyen d'appui ou d'accrochage 23 coopère avec la paroi périphérique du canal d'évacuation 10, c'est-à-dire avec la face intérieure du conduit vertical 7, et maintient fermement l'épaulement d'appui 15 de la tête de drainage 11 en appui au-dessus de la paroi horizontale 3.In the installed position, the support or hooking means 23 cooperates with the peripheral wall of the evacuation channel 10, that is to say with the inner face of the vertical conduit 7, and firmly holds the shoulder of support 15 of the drainage head 11 in support above the horizontal wall 3.

Selon l'exemple représenté, le moyen d'appui ou d'accrochage 23 comprend une pluralité d'organes d'appui 25 en une matière déformable élastiquement, aptes à coopérer, à l'encontre de leur élasticité, avec la paroi périphérique du canal d'évacuation 10, en des endroits espacés circonférentiellement, sous l'effet du moyen de sollicitation 24.According to the example shown, the support or attachment means 23 comprises a plurality of support members 25 made of an elastically deformable material, capable of cooperating, against their elasticity, with the peripheral wall of the channel evacuation 10, in circumferentially spaced locations, under the effect of the biasing means 24.

Plus particulièrement, les organes d'appui 25 sont formés par une pluralité de branches ou ailettes, par exemple métalliques, qui s'étendent depuis une portion centrale 26 du moyen d'appui ou d'accrochage. La portion centrale 26 présente une forme cylindrique. Par exemple, quatre branches disposées à 90° les unes par rapport aux autres sont prévues. Alternativement, il est possible de prévoir un nombre inférieur ou supérieur de branches.More particularly, the support members 25 are formed by a plurality of branches or fins, for example metal, which extend from a central portion 26 of the support or attachment means. The central portion 26 has a cylindrical shape. For example, four branches arranged at 90° relative to each other are provided. Alternatively, it is possible to provide a lower or higher number of branches.

Le moyen de sollicitation 24 comprend une tige verticale 27, qui s'étend axialement au canal d'évacuation 10 et donc au passage d'évacuation 14 et au conduit 21. L'extrémité inférieure de la tige 27 est accouplée à la portion centrale 26 et son extrémité supérieure traverse la portion supérieure de liaison 20 de la tête de drainage 11 et est pourvue d'un organe extérieur de manoeuvre 28 en appui au-dessus de la portion de jonction 20 de la tête de drainage 11.The biasing means 24 comprises a vertical rod 27, which extends axially to the evacuation channel 10 and therefore to the evacuation passage 14 and to the conduit 21. The lower end of the rod 27 is coupled to the central portion 26 and its upper end passes through the upper connection portion 20 of the drainage head 11 and is provided with an external maneuvering member 28 resting above the junction portion 20 of the drainage head 11.

L'extrémité inférieure de la tige 27 du moyen de sollicitation est accouplée par vissage à la portion centrale 26 du moyen d'appui ou d'accrochage. Dans ce but, la surface extérieure de cette extrémité inférieure est équipée d'un filetage extérieur (non représenté) en prise avec un taraudage intérieur (non représenté) de la portion centrale 26 du moyen d'appui ou d'accrochage.The lower end of the rod 27 of the biasing means is coupled by screwing to the central portion 26 of the support or hooking means. For this purpose, the outer surface of this lower end is equipped with an external thread (not shown) engaging with an internal thread (not shown) of the central portion 26 of the support or hooking means.

Comme illustré sur les figures 5 et 6, lorsque le moyen de montage 22 est en position de repos, c'est-à-dire n'est pas installé, les extrémités des branches 25 définissent un pourtour plus grand que le pourtour du canal d'évacuation 10, c'est-à-dire plus grand que le diamètre intérieur du conduit d'évacuation 7.As illustrated on the figure 5 And 6 , when the mounting means 22 is in the rest position, that is to say is not installed, the ends of the branches 25 define a perimeter greater than the perimeter of the evacuation channel 10, that is i.e. larger than the internal diameter of the exhaust duct 7.

L'installation de la tête de drainage 11 peut être réalisée de la manière suivante.The installation of the drainage head 11 can be carried out in the following way.

Lors de la mise en place de la tête de drainage 11 sur la construction 2, le conduit d'extrémité 21 étant introduit dans le canal d'évacuation 10 et l'épaulement 15 étant amené sur la surface extérieure 9 de la paroi horizontale 3, le moyen d'appui ou d'accrochage 23 est introduit du haut vers le bas dans le canal d'évacuation 10 sous l'effet du moyen de sollicitation 24 formé par la tige 27.When positioning the drainage head 11 on the construction 2, the end duct 21 being introduced into the evacuation channel 10 and the shoulder 15 being brought onto the outer surface 9 of the horizontal wall 3, the support or attachment means 23 is introduced from the top downwards into the evacuation channel 10 under the effect of the biasing means 24 formed by the rod 27.

Lors de cette introduction, les branches élastiques 25 se courbent et leurs extrémités, situées plus haut que la portion centrale 26, prennent appui et glissent contre la face intérieure du canal d'évacuation 10, l'organe de manoeuvre 28 étant en appui au-dessus de la portion supérieure 20 de la tête de drainage.During this introduction, the elastic branches 25 bend and their ends, located higher than the central portion 26, bear and slide against the inner face of the evacuation channel 10, the maneuvering member 28 being in contact with the above the upper portion 20 of the drainage head.

En position finale, la tête de drainage 11 est maintenue installée grâce à l'effet d'appui et d'accrochage des extrémités des branches élastiques 25 contre la paroi du canal d'évacuation 10, dans le sens opposé au sens d'introduction. Les extrémités des branches 25 en appui contre la paroi du canal d'évacuation 10 sont décalées axialement par rapport à la portion centrale 26 du moyen d'appui ou d'accrochage du côté de la tête de drainage 11.In the final position, the drainage head 11 is kept installed thanks to the bearing and hooking effect of the ends of the elastic branches 25 against the wall of the evacuation channel 10, in the opposite direction to the direction of insertion. The ends of the branches 25 bearing against the wall of the evacuation channel 10 are offset axially with respect to the central portion 26 of the support or hooking means on the side of the drainage head 11.

Comme indiqué précédemment, l'extrémité inférieure de la tige 27 est vissée dans la portion centrale 26 du moyen d'appui ou d'accrochage 23. Pour augmenter la force d'appui de la tête de drainage 11 au-dessus de la surface extérieure 9 de la construction 2, on tourne la tige 27 grâce à l'organe de manoeuvre 28, de sorte à tirer vers le haut la portion centrale 26 du moyen d'appui ou d'accrochage 23, de sorte à rapprocher la portion centrale 26 et la portion de jonction 20, et accroitre la courbure, et donc la déformation, des branches élastiques 25.As indicated above, the lower end of the rod 27 is screwed into the central portion 26 of the support or hooking means 23. To increase the pressing force of the drainage head 11 above the outer surface 9 of construction 2, the rod 27 is turned by means of the operating member 28, so as to pull up the central portion 26 of the support or hooking means 23, so as to bring the central portion 26 and the junction portion 20, and increase the curvature, and therefore the deformation, of the elastic branches 25.

Ceci permet d'assurer un bon plaquage axial de la tête de drainage 11 contre la surface extérieure 9 de la construction 2 sous l'effet de cette rotation de la tige 27 qui agit sur les branches 25. La rotation de la tige 27 assure une mise en pression axiale de la tête de drainage 11.This makes it possible to ensure good axial pressing of the drainage head 11 against the outer surface 9 of the construction 2 under the effect of this rotation of the rod 27 which acts on the branches 25. The rotation of the rod 27 ensures a axial pressurization of the drainage head 11.

Optionnellement, comme illustré sur la figure 6, le dispositif de drainage 1 comprend avantageusement un joint annulaire extérieur d'étanchéité 15a du côté de l'épaulement d'appui 15 de la tête de drainage 11, destiné à venir en appui sur le bord de la paroi 3 de la construction 2 entourant le canal d'évacuation 10. Spécifiquement, le joint annulaire extérieur d'étanchéité 15a entoure le conduit d'extrémité 21. Le joint annulaire extérieur d'étanchéité 15a est interposé axialement entre la tête de drainage 11 et le bord de la paroi 3 de la construction 2. Ainsi, lors de la mise en pression qui est réalisée lors de la rotation de la tige 27 dans la position finale de la tête de drainage 11, on obtient une compression axiale du joint annulaire extérieur d'étanchéité 15a entre cette tête 11 et le bord de la paroi 3 de la construction 2.Optionally, as shown in figure 6 , the drainage device 1 advantageously comprises an outer annular seal 15a on the side of the bearing shoulder 15 of the drainage head 11, intended to bear against the edge of the wall 3 of the construction 2 surrounding the exhaust channel 10. Specifically, the outer ring seal 15a surrounds the end conduit 21. The outer annular sealing gasket 15a is interposed axially between the drainage head 11 and the edge of the wall 3 of the construction 2. Thus, during the pressurization which is carried out during the rotation of the rod 27 in the final position of the drainage head 11, an axial compression of the outer annular seal 15a is obtained between this head 11 and the edge of the wall 3 of the construction 2.

Le dispositif de drainage 1 comprend en outre un capot perforé 29, en forme de cloche, qui entoure à distance la tête de drainage 1 et est monté sur cette dernière. Le capot perforé 29 comprend une paroi périphérique 30 pourvue d'une pluralité de perforations 30a, dont le bord inférieur est adjacent à la face supérieure 9 de la paroi horizontale 3 de la construction 2 et comprend un fond perforé 31 qui passe au-dessus de l'organe de manoeuvre 28. Le capot perforé 29 est maintenu grâce à une vis 32 qui traverse le fond 31 et est vissée dans l'organe de manoeuvre 28.The drainage device 1 further comprises a perforated cover 29, bell-shaped, which remotely surrounds the drainage head 1 and is mounted on the latter. The perforated cover 29 comprises a peripheral wall 30 provided with a plurality of perforations 30a, the lower edge of which is adjacent to the upper face 9 of the horizontal wall 3 of the construction 2 and comprises a perforated bottom 31 which passes above the operating member 28. The perforated cover 29 is held by a screw 32 which passes through the bottom 31 and is screwed into the operating member 28.

Il résulte de ce qui précède que la tête de drainage 11 et le capot 29 sont maintenus sans aucune intervention sur la paroi 3 de la construction 2 et sans aucune intervention dans le canal d'évacuation 10 délimité par le conduit 7. Le dispositif de drainage 1 peut donc être installé sur une construction neuve ou déjà existante.It follows from the above that the drainage head 11 and the cover 29 are maintained without any intervention on the wall 3 of the construction 2 and without any intervention in the evacuation channel 10 delimited by the conduit 7. The drainage device 1 can therefore be installed on a new or existing construction.

Selon un autre exemple de réalisation illustré sur les figures 7 et 8, un dispositif de drainage 101 est destiné à être installé sur une construction 102 qui comprend une paroi horizontale 103 bordée par une paroi verticale 104. Le dispositif de drainage 101 est destiné à être installé sur la paroi verticale 104 de sorte à évacuer l'eau se trouvant sur la paroi horizontale 103.According to another exemplary embodiment illustrated in the figure 7 And 8 , a drainage device 101 is intended to be installed on a construction 102 which comprises a horizontal wall 103 bordered by a vertical wall 104. The drainage device 101 is intended to be installed on the vertical wall 104 so as to evacuate the water located on the horizontal wall 103.

De façon équivalente à l'exemple précédent, la paroi verticale 104 de la construction 102 présente un trou 105 équipé d'un conduit d'évacuation 106 relié à l'étanchéité des parois horizontales et verticales 103 et 104, de sorte à délimiter un canal d'évacuation 107.Equivalently to the previous example, the vertical wall 104 of the construction 102 has a hole 105 equipped with an evacuation conduit 106 connected to the sealing of the horizontal and vertical walls 103 and 104, so as to delimit a channel evacuation 107.

Le conduit d'évacuation 106 débouche à proximité de la paroi horizontale 104 et s'étend par exemple de façon légèrement inclinée vers le bas depuis son embouchure, perpendiculairement à une surface inférieure extérieure légèrement inclinée 108 de la paroi verticale 104 qui entoure cette embouchure.The evacuation duct 106 opens near the horizontal wall 104 and extends for example in a slightly inclined way downwards from its mouth, perpendicular to a surface. slightly inclined outer bottom 108 of the vertical wall 104 which surrounds this mouth.

Le dispositif de drainage 101 comprend une tête de drainage 109 qui comprend une paroi extérieure 110, en forme de caisson, qui délimite un espace interne de récupération 111 et qui communique avec l'extérieur par au moins un passage de récupération, destiné à laisser entrer l'eau vers l'espace de récupération 111, et avec le canal d'évacuation 107 par un passage d'évacuation 112. Le passage d'évacuation 112 est formé latéralement à la paroi extérieure 110 de la tête de drainage 109.The drainage device 101 comprises a drainage head 109 which comprises an outer wall 110, in the form of a box, which delimits an internal recovery space 111 and which communicates with the outside by at least one recovery passage, intended to let in water to the collection space 111, and with the drainage channel 107 through a drainage passage 112. The drainage passage 112 is formed laterally to the outer wall 110 of the drainage head 109.

Plus spécifiquement, la paroi extérieure 110 de la tête de drainage 109 se présente sous la forme d'un coude et présente une branche inférieure 113, quasi horizontale, et une branche verticale 114 qui s'étend vers le haut. La paroi extérieure 110 peut être fabriquée à partir de deux portions de tubes coupés en biais à 45°, les bords coupés à 45° étant assemblés l'un à l'autre.More specifically, the outer wall 110 of the drainage head 109 is in the form of an elbow and has a lower branch 113, which is almost horizontal, and a vertical branch 114 which extends upwards. The outer wall 110 can be made from two portions of tubing cut at an angle at 45°, the edges cut at 45° being joined together.

De façon équivalente à la tête de drainage 11, l'extrémité de la branche inférieure 113 de la paroi extérieure 110 est pourvue d'un épaulement annulaire intérieur d'appui 115 en appui, cette fois latéralement, sur la surface extérieure 108 de la paroi verticale 104, autour du canal d'évacuation 107. La tête de drainage 109 comprend un conduit d'extrémité 116 qui s'étend depuis le bord intérieur de l'épaulement d'appui 115 et qui est engagé dans le canal d'évacuation 107. Le bord intérieur de l'épaulement d'appui 115 et le conduit d'extrémité 116 déterminent un passage d'évacuation 112.Equivalently to the drainage head 11, the end of the lower branch 113 of the outer wall 110 is provided with an inner annular bearing shoulder 115 resting, this time laterally, on the outer surface 108 of the wall. vertical 104, around the evacuation channel 107. The drainage head 109 comprises an end conduit 116 which extends from the inside edge of the bearing shoulder 115 and which is engaged in the evacuation channel 107 The inside edge of the bearing shoulder 115 and the end duct 116 define an evacuation passage 112.

Il résulte de ce montage que la branche inférieure 113 de la paroi extérieure 110 est adjacente à la surface de la paroi horizontale 103 de la construction 102.It follows from this assembly that the lower branch 113 of the outer wall 110 is adjacent to the surface of the horizontal wall 103 of the construction 102.

La branche supérieure 114 de la paroi extérieure 110 s'étend à distance de la paroi verticale 104 de la construction 102 et, de façon équivalente au dispositif de drainage 1, est renflée puis rétrécie, l'extrémité rétrécie étant pourvue d'une portion supérieure de jonction 117.The upper leg 114 of the outer wall 110 extends away from the vertical wall 104 of the construction 102 and, equivalent to the drainage device 1, is bulged and then narrowed, the narrowed end being provided with an upper portion junction 117.

Avantageusement, la paroi extérieure 110 présente un passage inférieur calibré de récupération 118 (Figure 9) et un passage supérieur de récupération par déversement 119, qui peuvent être formés par des découpes de la paroi extérieure 110. Le passage inférieur de récupération 118 et le passage supérieur de récupération 119 sont décalés verticalement. Néanmoins, le passage inférieur de récupération 118 et le passage supérieur de récupération 119 pourraient communiquer.Advantageously, the outer wall 110 has a lower calibrated recovery passage 118 ( Figure 9 ) and an upper spill recovery passage 119, which may be formed by cutouts in the outer wall 110. The lower recovery passage 118 and the upper recovery passage 119 are offset vertically. Nevertheless, the lower recovery passage 118 and the upper recovery passage 119 could communicate.

Le fonctionnement de la tête de drainage 110, montée la paroi verticale 104 sur la construction 102, est équivalent au fonctionnement de la tête de drainage 11 montée sur la paroi horizontale 3 de la construction 2.The operation of drain head 110, mounted on vertical wall 104 on building 102, is equivalent to the operation of drain head 11 mounted on horizontal wall 3 of building 2.

L'eau de pluie se trouvant sur la paroi horizontale 103 de la construction 102 et retenue par la paroi verticale 104, autour de la paroi extérieure 110 de la tête de drainage 109, peut alors être évacuée de la manière suivante.The rainwater lying on the horizontal wall 103 of the construction 102 and retained by the vertical wall 104, around the outer wall 110 of the drainage head 109, can then be evacuated in the following manner.

L'eau de pluie s'écoule au travers du passage inférieur calibré de récupération 118 vers l'espace de récupération 111 délimité par la tête de drainage 11 puis s'écoule depuis l'espace de récupération 111 au travers du passage latéral d'évacuation 112 vers le canal incliné d'évacuation 107.The rainwater flows through the lower calibrated recovery passage 118 towards the recovery space 111 delimited by the drainage head 11 then flows from the recovery space 111 through the lateral evacuation passage 112 to the inclined evacuation channel 107.

Lorsque le débit de l'eau au travers du passage inférieur calibré de récupération 118 est insuffisant, le niveau de l'eau monte puis atteint le passage supérieur de récupération 119 qui assure le déversement de l'eau dans l'espace de récupération 111 puis l'évacuation par le canal d'évacuation 107, à un débit plus grand que celui qui est possible par le passage calibré de récupération 118.When the water flow through the lower calibrated recovery passage 118 is insufficient, the water level rises and then reaches the upper recovery passage 119 which ensures the discharge of water into the recovery space 111 then evacuation through the evacuation channel 107, at a higher rate than that which is possible through the calibrated recovery passage 118.

Le dispositif de drainage 101 comprend un moyen de montage 120 destiné au maintien de la tête de drainage 109 en position installée latéralement à la paroi verticale 104 de la construction 102.The drainage device 101 includes mounting means 120 for holding the drainage head 109 in a position installed laterally to the vertical wall 104 of the construction 102.

Le moyen de montage 120 comprend un moyen d'appui ou d'accrochage 121 qui coopère avec la paroi périphérique du canal d'évacuation 107 et qui comprend, comme illustré sur la figure 8, une pluralité d'organes d'appui 122 en une matière déformable élastiquement, formés par une pluralité de branches ou ailettes, par exemple métalliques, qui s'étendent depuis une portion centrale 123, qui sont fléchies à l'encontre de leur élasticité et dont les extrémités sont en prise avec la paroi périphérique du canal d'évacuation 107.The assembly means 120 comprises a support or hooking means 121 which cooperates with the peripheral wall of the evacuation channel 107 and which comprises, as illustrated in the figure 8 , a plurality of support members 122 made of a deformable material elastically, formed by a plurality of branches or fins, for example metallic, which extend from a central portion 123, which are bent against their elasticity and whose ends are in engagement with the peripheral wall of the channel of evacuation 107.

Le moyen de montage 120 comprend, à titre de moyen de sollicitation 124 reliant le moyen d'appui ou d'accrochage 121 et la tête de drainage 109, une tige 125, quasi horizontale, qui s'étend axialement au canal d'évacuation 107 et donc au passage d'évacuation 112 et au conduit d'extrémité 116. Une extrémité de la tige 124 est accouplée à la portion centrale 123 et son autre extrémité traverse la partie de la paroi extérieure 110 de la tête de drainage 109, opposée au passage d'évacuation 112 et renforcée par une rondelle 126, et est pourvue d'un organe extérieur de manoeuvre 127 en appui au-dessus de la rondelle 126 de la paroi extérieure 110.The mounting means 120 comprises, as biasing means 124 connecting the support or attachment means 121 and the drainage head 109, a rod 125, almost horizontal, which extends axially to the evacuation channel 107 and therefore to the evacuation passage 112 and to the end conduit 116. One end of the rod 124 is coupled to the central portion 123 and its other end passes through the part of the outer wall 110 of the drainage head 109, opposite the evacuation passage 112 and reinforced by a washer 126, and is provided with an external maneuvering member 127 resting above the washer 126 of the outer wall 110.

Le moyen de montage 120 est mis en place et fonctionne de façon équivalente au moyen de montage 24 de l'exemple précédent, de sorte à maintenir la tête de drainage en appui contre la surface extérieure 108 de la paroi verticale 104 de la construction 102.The mounting means 120 is set up and functions equivalently to the mounting means 24 of the previous example, so as to maintain the drainage head resting against the outer surface 108 of the vertical wall 104 of the construction 102.

Le dispositif de drainage 101 comprend en outre un capot perforé 128 installé à distance de la tête de drainage 109.The drainage device 101 further comprises a perforated cover 128 installed at a distance from the drainage head 109.

Le capot perforé 128 comprend une paroi latérale 129, de section horizontale en forme de C, dont le bord inférieur est adjacent à la surface de la paroi horizontale 103 de la construction 102 et une paroi supérieure horizontale 130 en appui sur la portion supérieure de jonction 117 de la tête de drainage 109, à laquelle elle est fixée par l'intermédiaire d'une vis 131.The perforated cover 128 comprises a side wall 129, of horizontal C-shaped section, the lower edge of which is adjacent to the surface of the horizontal wall 103 of the construction 102 and a horizontal upper wall 130 resting on the upper junction portion 117 of the drain head 109, to which it is fixed by means of a screw 131.

Selon un autre exemple de réalisation, non revendiqué, illustré sur la figure 9, un dispositif de drainage 201 est destiné à être installé sur une construction 202 qui comprend une paroi horizontale 203, dans le but d'évacuer l'eau se trouvant au-dessus de cette paroi horizontale 203.According to another exemplary embodiment, not claimed, illustrated in the figure 9 , a drainage device 201 is intended to be installed on a construction 202 which comprises a horizontal wall 203, in order to evacuate the water located above this horizontal wall 203.

De façon équivalente à la construction 2 de la figure 1, la paroi horizontale 203 de la construction 202 présente un canal vertical d'évacuation 204 délimité par un conduit vertical d'évacuation 205 dont l'extrémité supérieure est reliée à l'étanchéité de la surface de la paroi horizontale 203.Equivalently to construction 2 of the figure 1 , the horizontal wall 203 of the construction 202 has a vertical evacuation channel 204 delimited by a vertical evacuation conduit 205 whose the upper end is connected to the sealing of the surface of the horizontal wall 203.

Le dispositif de drainage 201 comprend une tête de drainage 206 qui délimite un espace interne de récupération 207 au-dessus du canal d'évacuation 204.The drainage device 201 comprises a drainage head 206 which delimits an internal recovery space 207 above the evacuation channel 204.

La tête de drainage 206 comprend une paroi extérieure 208, en forme de cloche, qui comprend une paroi périphérique cylindrique verticale 209 dont le bord inférieur est pourvu d'un épaulement annulaire d'appui 210 en appui sur la surface extérieure 203a de la paroi horizontale 203 de la construction 202, autour du canal d'évacuation 204, par l'intermédiaire d'un joint annulaire d'étanchéité 211 et qui délimite un passage d'évacuation 212. La paroi extérieure 208 comprend une paroi radiale supérieure 213.The drainage head 206 comprises an outer wall 208, bell-shaped, which comprises a vertical cylindrical peripheral wall 209 whose lower edge is provided with an annular bearing shoulder 210 resting on the outer surface 203a of the horizontal wall 203 of construction 202, around the evacuation channel 204, via an annular seal 211 and which delimits an evacuation passage 212. The outer wall 208 comprises an upper radial wall 213.

La paroi périphérique 209 présente au moins un passage de récupération. Par exemple, la paroi périphérique 209 présente des passages inférieurs calibrés de récupération 214 et des passages supérieurs de déversement 215, qui communiquent entre eux. La paroi radiale supérieure 213 peut également présenter des passages de récupération.The peripheral wall 209 has at least one recovery passage. For example, the peripheral wall 209 has lower calibrated recovery passages 214 and upper discharge passages 215, which communicate with each other. The upper radial wall 213 may also have recovery passages.

Les écoulements de l'eau via la tête de drainage 201 sont équivalents à ceux via la tête de drainage 11 décrite précédemment.The flows of water via the drain head 201 are equivalent to those via the drain head 11 described above.

Le dispositif de drainage 201 comprend un moyen de montage 216 destiné au maintien de la tête de drainage 206 en position installée au-dessus de la paroi horizontale 203 de la construction 202.Drainage device 201 includes mounting means 216 for holding drainage head 206 in the installed position above horizontal wall 203 of building 202.

Le moyen de montage 216 comprend un moyen d'appui ou d'accrochage 217 destiné à coopérer avec la paroi périphérique du canal d'évacuation 204, c'est-à-dire avec la surface intérieure du conduit d'évacuation 205.The mounting means 216 comprises a support or hooking means 217 intended to cooperate with the peripheral wall of the evacuation channel 204, that is to say with the inner surface of the evacuation duct 205.

Le moyen d'appui ou d'accrochage 217 comprend une pluralité d'organes espacés d'appui 218, qui sont formés par des branches, par exemple métalliques, et comprennent des portions allongées 219 qui s'étendent depuis la paroi radiale supérieure 213 de la tête de drainage 206, qui traversent vers le bas l'espace de récupération 207 et pénètrent dans le canal d'évacuation 204. Dans l'exemple de réalisation illustré, les branches 218 sont au nombre de deux. En variante, il est possible de prévoir un nombre supérieur de branches 218.The support or attachment means 217 comprises a plurality of spaced support members 218, which are formed by branches, for example metal, and include elongated portions 219 which extend from the upper radial wall 213 of the drainage head 206, which pass through the recovery space 207 downwards and enter the evacuation channel 204. In the example embodiment illustrated, the branches 218 are two in number. Alternatively, it is possible to provide a greater number of branches 218.

Les parties inférieures d'extrémité 220 des portions allongées 219 sont inclinées vers la paroi périphérique du canal d'évacuation 204. Les portions allongées 219 sont situées à distance les unes des autres de sorte que leurs extrémités inférieures puissent venir en appui contre la paroi périphérique du canal d'évacuation 204, en des endroits espacés dans le sens périphérique.The lower end portions 220 of the elongated portions 219 are inclined towards the peripheral wall of the evacuation channel 204. The elongated portions 219 are located at a distance from each other so that their lower ends can bear against the peripheral wall of the evacuation channel 204, in places spaced in the peripheral direction.

Les branches 218 comprennent des portions supérieures d'actionnement 221 reliées aux extrémités supérieures des portions allongées 219 en formant des plis de pivotement 222 aptes à venir en appui contre la face inférieure de la paroi radiale supérieure 213 de la tête de drainage 206. Les portions supérieures d'actionnement 221 sont adjacentes à la paroi radiale supérieure 213 de la tête de drainage 206 et s'étendent radialement en direction de la paroi périphérique 209 de la tête de drainage 206.The branches 218 comprise upper actuating portions 221 connected to the upper ends of the elongated portions 219 by forming pivoting folds 222 able to bear against the underside of the upper radial wall 213 of the drainage head 206. 221 are adjacent to the upper radial wall 213 of the drainage head 206 and extend radially in the direction of the peripheral wall 209 of the drainage head 206.

Le moyen de montage 216 comprend, à titre de moyen de sollicitation reliant le moyen d'appui ou d'accrochage 217 et la tête de drainage 206, une pluralité de vis de traction 224 qui traversent la paroi radiale supérieure 213 de la tête de drainage 206 et qui sont en prise avec les portions supérieures d'actionnement 221 des branches formant les organes d'appui 218.The mounting means 216 comprises, as biasing means connecting the support or hooking means 217 and the drainage head 206, a plurality of traction screws 224 which pass through the upper radial wall 213 of the drainage head 206 and which engage with the upper actuating portions 221 of the branches forming the support members 218.

L'installation du dispositif de drainage 201 peut être réalisée de la manière suivante.The installation of the drainage device 201 can be carried out in the following way.

On place la tête de drainage en appui au-dessus de la surface extérieure 203a de la construction 202.The drainage head is placed in support above the outer surface 203a of the construction 202.

En même temps, les vis de traction 224 étant desserrées, on engage librement les portions allongées 219 des branches formant les organes d'appui 218 dans le canal d'évacuation 204 de la construction 202.At the same time, the traction screws 224 being loosened, the elongated portions 219 of the branches forming the support members 218 are freely engaged in the evacuation channel 204 of the construction 202.

Puis, en actionnant les vis de traction 224, les portions supérieures d'actionnement 221 des branches formant les organes d'appui 218 peuvent être rapprochées de la face inférieure de la paroi radiale supérieure 216 de la tête de drainage 206, ce qui provoque, substantiellement radialement, le pivotement des portions allongées 219 autour des plis de pivotement 222 en appui contre la paroi radiale supérieure 216 et amène les extrémités inférieures des portions allongées 220 en appui contre la paroi périphérique du canal d'évacuation 204, en induisant des forces d'appui et d'accrochage, de sorte à maintenir la tête de drainage 206 dans sa portion installée en appui sur la surface 203a de la construction 202.Then, by actuating the traction screws 224, the upper actuating portions 221 of the branches forming the support members 218 can be brought closer to the underside of the upper radial wall 216 of the drainage head 206, which causes, substantially radially, the pivoting of the elongated portions 219 around the pivoting folds 222 in abutment against the upper radial wall 216 and brings the lower ends of the elongated portions 220 into abutment against the peripheral wall of the evacuation channel 204, by inducing forces of support and attachment, so as to maintain the drainage head 206 in its installed portion resting on the surface 203a of the construction 202.

Les branches formant les organes espacés d'appui 218 peuvent être rigides ou en une matière déformable élastiquement, ces branches étant déformées contre la paroi périphérique du canal d'évacuation 204 et exerçant des efforts d'appui à l'encontre de leur élasticité.The branches forming the spaced bearing members 218 may be rigid or made of an elastically deformable material, these branches being deformed against the peripheral wall of the evacuation channel 204 and exerting bearing forces against their elasticity.

De façon équivalente au dispositif de drainage 1, le dispositif de drainage 201 peut en outre comprendre un capot perforé (non représenté) entourant à distance la tête de drainage 206 et monté sur cette dernière.Equivalently to the drainage device 1, the drainage device 201 may further comprise a perforated cover (not shown) remotely surrounding the drainage head 206 and mounted on the latter.

Selon un autre exemple de réalisation (non représenté et non revendiqué), un moyen de montage d'une tête de drainage comprend un moyen d'appui et d'accrochage comprenant des branches formant des organes espacés d'appui, articulées sur de la tête de drainage et engagées dans un canal d'évacuation d'une construction, et un moyen de sollicitation comprenant un organe d'écartement placé dans l'espace entre ces branches et un organe de liaison reliant l'organe d'écartement et la tête de drainage formé par exemple par une tige axiale mobile à rotation ou axialement.According to another exemplary embodiment (not shown and not claimed), a means for mounting a drainage head comprises a support and hooking means comprising branches forming spaced support members, articulated on the head drainage and engaged in a drainage channel of a construction, and a biasing means comprising a spacer member placed in the space between these branches and a connecting member connecting the spacer member and the head of drainage formed for example by an axial rod movable in rotation or axially.

Par exemple, sous un effet axial de cette tige, grâce à un moyen de vis-écrou entre la tige et l'organe d'écartement et/ou la tête de drainage, l'organe d'écartement peut être déplacé axialement, dans un sens ou dans l'autre, de sorte à agir par traction ou poussée, en glissant, sur des portions non axiales des branches formant des organes d'appui dans le sens qui applique les extrémités de ces branches contre la paroi du canal d'évacuation afin de maintenir la tête de de drainage en appui sur la surface de la construction autour du canal d'évacuation.For example, under an axial effect of this rod, thanks to a screw-nut means between the rod and the spacer member and/or the drainage head, the spacer member can be moved axially, in a direction or the other, so as to act by pulling or pushing, by sliding, on non-axial portions of the branches forming support members in the direction which presses the ends of these branches against the wall of the evacuation channel in order to maintain the head of drain in support on the surface of the construction around the channel of evacuation.

Les branches formant des organes d'appui, l'organe d'écartement et la tige axiale sont agencées pour laisser passer l'eau.The branches forming support members, the spacer member and the axial rod are arranged to allow water to pass.

Par exemple, selon l'exemple de réalisation non revendiqué illustré sur les figures 10 et 11 de conception proche de celui de la figure 9, un dispositif de drainage 301 est destiné à être installé sur une construction 302 qui comprend une paroi horizontale 303, dans le but d'évacuer l'eau se trouvant au-dessus de cette paroi horizontale 303.For example, according to the unclaimed exemplary embodiment illustrated in the figure 10 And 11 of design close to that of the figure 9 , a drainage device 301 is intended to be installed on a construction 302 which comprises a horizontal wall 303, in order to evacuate the water located above this horizontal wall 303.

De façon équivalente à la construction de la figure 9, la paroi horizontale 303 de la construction 302 présente un canal vertical d'évacuation 304 délimité par un conduit vertical d'évacuation 305 dont l'extrémité supérieure est reliée à l'étanchéité (non représentée) de la surface de la paroi horizontale 303.Equivalently to the construction of the figure 9 , the horizontal wall 303 of the construction 302 has a vertical evacuation channel 304 delimited by a vertical evacuation duct 305 whose upper end is connected to the sealing (not shown) of the surface of the horizontal wall 303.

Le dispositif de drainage 301 comprend une tête de drainage 306 qui délimite un espace interne de récupération 307 au-dessus du canal d'évacuation 304.The drainage device 301 comprises a drainage head 306 which delimits an internal recovery space 307 above the evacuation channel 304.

La tête de drainage 306 comprend une paroi extérieure 308, en forme de cloche, qui comprend une paroi périphérique cylindrique verticale 309 dont le bord inférieur est pourvu d'un épaulement annulaire d'appui 310 en appui sur la surface extérieure 303a de la paroi horizontale 303 de la construction 302, autour du canal d'évacuation 304, par l'intermédiaire d'un joint annulaire d'étanchéité 311 et qui délimite un passage d'évacuation 312. La paroi extérieure 308 comprend une paroi radiale supérieure 313.The drainage head 306 comprises an outer wall 308, bell-shaped, which comprises a vertical cylindrical peripheral wall 309 whose lower edge is provided with an annular bearing shoulder 310 resting on the outer surface 303a of the horizontal wall 303 of construction 302, around the evacuation channel 304, via an annular seal 311 and which delimits an evacuation passage 312. The outer wall 308 comprises an upper radial wall 313.

La paroi périphérique 309 présente au moins un passage de récupération (non représenté) comme indiqué dans les exemples de réalisation précédents. De façon identique à l'exemple de réalisation précédent, Par exemple, la paroi périphérique 309 peut présenter des passages inférieurs calibrés de récupération et des passages supérieurs de déversement, qui communiquent entre eux. La paroi radiale supérieure 313 peut également présenter des passages de récupération.The peripheral wall 309 has at least one recovery passage (not shown) as indicated in the previous embodiments. Identically to the previous embodiment, for example, the peripheral wall 309 may have lower calibrated recovery passages and upper discharge passages, which communicate with each other. The upper radial wall 313 may also have recovery passages.

Les écoulements de l'eau via la tête de drainage 301 sont équivalents à ceux via la tête de drainage 11 décrite précédemment.The flows of water via the drain head 301 are equivalent to those via the drain head 11 described above.

Le dispositif de drainage 301 comprend un moyen de montage 316 destiné au maintien de la tête de drainage 306 en position installée au-dessus de la paroi horizontale 303 de la construction 302.Drainage device 301 includes mounting means 316 for holding drainage head 306 in the installed position above horizontal wall 303 of building 302.

Le moyen de montage 316 comprend un moyen d'appui ou d'accrochage 317 destiné à coopérer avec la paroi périphérique du canal d'évacuation 304, c'est-à-dire avec la surface intérieure du conduit d'évacuation 305.The mounting means 316 comprises a support or hooking means 317 intended to cooperate with the peripheral wall of the evacuation channel 304, that is to say with the inner surface of the evacuation conduit 305.

Le moyen d'appui ou d'accrochage 317 comprend une pluralité d'organes espacés d'appui 318, qui sont formés par des lames ou branches, par exemple métalliques, et comprennent des portions allongées 319 qui s'étendent depuis la paroi radiale supérieure 313 de la tête de drainage 206, qui traversent vers le bas l'espace de récupération 307 et pénètrent dans le canal d'évacuation 304. Dans l'exemple de réalisation illustré, les branches 318 sont au nombre de deux. En variante, il est possible de prévoir un nombre supérieur de branches 318.The support or attachment means 317 comprises a plurality of spaced support members 318, which are formed by blades or branches, for example metal, and include elongated portions 319 which extend from the upper radial wall 313 of the drainage head 206, which pass through the recovery space 307 downwards and enter the evacuation channel 304. In the illustrated embodiment, the branches 318 are two in number. Alternatively, it is possible to provide a greater number of branches 318.

Les parties inférieures d'extrémité 320 des portions allongées 319 sont inclinées vers la paroi périphérique du canal d'évacuation 304. Les portions allongées 319 sont situées à distance les unes des autres de sorte que leurs extrémités inférieures puissent venir en appui contre la paroi périphérique du canal d'évacuation 304, en des endroits espacés dans le sens périphérique. Contrairement à l'exemple de réalisation illustré à la figure 9, les parties inférieures d'extrémité 320 des branches présentent ici chacune une extrémité libre recourbée vers l'intérieur du canal d'évacuation 304.The lower end portions 320 of the elongated portions 319 are inclined towards the peripheral wall of the evacuation channel 304. The elongated portions 319 are located at a distance from each other so that their lower ends can bear against the peripheral wall of the evacuation channel 304, in places spaced in the peripheral direction. Unlike the example embodiment illustrated in figure 9 , the lower end portions 320 of the branches here each have a free end curved towards the inside of the evacuation channel 304.

Les branches 318 comprennent des portions supérieures d'actionnement 321 reliées aux extrémités supérieures des portions allongées 319 en formant des plis 322 aptes à venir en appui contre la face inférieure de la paroi radiale supérieure 313 de la tête de drainage 306 comme cela sera indiqué par la suite. Les portions supérieures d'actionnement 321 sont adjacentes à la paroi radiale supérieure 313 de la tête de drainage 306 et s'étendent radialement en direction de la paroi périphérique 309 de la tête de drainage 306.The branches 318 comprise upper actuating portions 321 connected to the upper ends of the elongated portions 319 by forming folds 322 able to bear against the underside of the upper radial wall 313 of the drainage head 306 as will be indicated by the following. Upper actuation portions 321 are adjacent upper radial wall 313 of drain head 306 and extend radially toward peripheral wall 309 of drain head 306.

Le moyen de montage 316 comprend un moyen de sollicitation 323 reliant le moyen d'appui ou d'accrochage 317 et la tête de drainage 306. Le moyen de sollicitation 323 comprend une pluralité de vis 324 de maintien qui traversent la paroi radiale supérieure 313 de la tête de drainage 306 et qui sont en prise avec les portions supérieures d'actionnement 321 des branches 318. Les têtes des vis 324 viennent axialement en appui contre la face supérieure de la paroi radiale supérieure 313 de la tête de drainage 306.The mounting means 316 comprises a biasing means 323 connecting the support or hooking means 317 and the drainage head 306. The biasing means 323 comprises a plurality of retaining screws 324 which pass through the upper radial wall 313 of the the head of drainage 306 and which engage with the upper actuating portions 321 of the branches 318. The heads of the screws 324 bear axially against the upper face of the upper radial wall 313 of the drainage head 306.

Contrairement à l'exemple de réalisation illustré à la figure 9, les vis 324 sont montées sur la tête de drainage 306 avec possibilité de coulissement libre dans le sens radial. Dans ce but, des fentes 325 radiales sont ménagées sur la paroi radiale supérieure 313 de la tête de drainage et permettent le passage des vis 334. Les fentes 325 sont diamétralement opposées.Unlike the example embodiment illustrated in figure 9 , the screws 324 are mounted on the drainage head 306 with the possibility of free sliding in the radial direction. For this purpose, radial slots 325 are provided on the upper radial wall 313 of the drainage head and allow the passage of the screws 334. The slots 325 are diametrically opposed.

Dans cet exemple de réalisation, le moyen de sollicitation 323 comprend également une tige 327 verticale, qui s'étend axialement au canal d'évacuation 304. La tige 327 s'étend axialement à l'intérieur de la tête de drainage 306 et à l'intérieur du conduit d'évacuation 305. La tige 327 s'étend au travers de la paroi radiale supérieure 313 de la tête de drainage. La tige 327 s'étend axialement en saillie par rapport à la tête de drainage 306. La surface extérieure de la tige 327 est équipée d'un filetage extérieur (non référencé). La paroi radiale supérieure 313 de la tête de drainage comprend un taraudage (non référencé) en prise avec le filetage extérieur de la tige 327.In this exemplary embodiment, the biasing means 323 also comprises a vertical rod 327, which extends axially to the evacuation channel 304. The rod 327 extends axially inside the drainage head 306 and to the inside drain duct 305. Stem 327 extends through upper radial wall 313 of the drain head. Stem 327 extends axially projecting from drain head 306. The outer surface of stem 327 is provided with an external thread (not referenced). The upper radial wall 313 of the drainage head includes a thread (not referenced) in engagement with the external thread of the rod 327.

Le moyen de sollicitation 323 comprend encore un organe d'écartement 328 monté sur la tige 327 et disposé dans l'espace entre les branches 318. L'organe d'écartement 328 est disposé dans l'espace entre les parties inférieures d'extrémité 320 des branches qui sont situées dans le conduit d'évacuation 305.The biasing means 323 further comprises a spacer member 328 mounted on the rod 327 and disposed in the space between the branches 318. The spacer member 328 is disposed in the space between the lower end portions 320 branches that are located in the exhaust duct 305.

L'organe d'écartement 328 se présente sous la forme d'une rondelle. L'organe d'écartement 328 est équipé d'un alésage taraudé (non référencé) en prise avec le filetage extérieur de la tige 327. Comme illustré plus visiblement à la figure 12, l'organe d'écartement 328 est pourvu d'une pluralité de trous 329 oblongs traversants pour le passage des eaux pluviales.The spacer member 328 is in the form of a washer. The spacer 328 is equipped with a threaded bore (not referenced) in engagement with the external thread of the rod 327. As illustrated more visibly at figure 12 , the spacer member 328 is provided with a plurality of through oblong holes 329 for the passage of rainwater.

En se référant de nouveau aux figures 10 et 11, le moyen de sollicitation 323 comprend aussi une platine 330 de compression montée sur la tige 327. La platine 330 comprend un alésage central pour son montage sur la tige 327. L'alésage de la platine est lisse, i.e. dépourvu de filetage en prise avec celui de la tige 327Referring again to figure 10 And 11 , the biasing means 323 also includes a compression plate 330 mounted on the rod 327. The plate 330 includes a central bore for its mounting on the rod 327. The bore of the plate is smooth, ie without thread engaging with that of the rod 327

La platine 330 de compression est solidaire en translation de la tige 327. Dans l'exemple de réalisation illustré, deux butées 331 (figure 13) sont fixées à cet effet sur la surface extérieure de la tige 327 axialement de part et d'autre de la platine 330 de compression.The compression plate 330 is integral in translation with the rod 327. In the illustrated embodiment, two stops 331 ( figure 13 ) are fixed for this purpose on the outer surface of the rod 327 axially on either side of the plate 330 of compression.

La platine 330 de compression est montée à l'intérieur de la tête de drainage 306. La platine 330 est montée axialement l'intérieur de la tête de drainage à proximité de l'épaulement 310 et du joint d'étanchéité 311. Dans la position illustrée à la figure 10, la platine 330 de compression est axialement à distance de l'épaulement 310 et du joint d'étanchéité 311. Comme illustré plus visiblement à la figure 14, la platine 330 de compression est pourvu d'une pluralité de trous 332 oblongs traversants pour le passage des eaux pluviales. Les branches 318 s'étendent au travers des trous 332 oblongs de la platine 330 de compression.The compression plate 330 is mounted inside the drainage head 306. The plate 330 is mounted axially inside the drainage head near the shoulder 310 and the seal 311. In the position illustrated at figure 10 , the compression plate 330 is axially spaced from the shoulder 310 and the seal 311. As illustrated more visibly in figure 14 , the compression plate 330 is provided with a plurality of through oblong holes 332 for the passage of rainwater. The branches 318 extend through the oblong holes 332 of the plate 330 of compression.

L'installation du dispositif de drainage 301 peut être réalisée de la manière suivante.The installation of the drainage device 301 can be carried out in the following way.

On place la tête de drainage 301 en appui au-dessus de la surface extérieure 303a de la construction 302 comme cela est représenté à la figure 10.The drainage head 301 is placed in abutment above the outer surface 303a of the construction 302 as shown in figure 10 .

Dans cette position, on fait coulisser radialement vers l'intérieur les vis 334 dans les fentes 325 pour amener les parties inférieures d'extrémité 320 des branches 318 en appui contre la paroi périphérique du canal d'évacuation 304. Cette première position intermédiaire d'assemblage est illustrée à la figure 15.In this position, the screws 334 are made to slide radially inwards in the slots 325 to bring the lower end parts 320 of the branches 318 into abutment against the peripheral wall of the evacuation channel 304. This first intermediate position of assembly is shown in figure 15 .

Ensuite, on entraine en rotation la tige 327 dans le sens horaire par l'intermédiaire de son extrémité supérieure, ce qui a pour effet de faire remonter axialement l'organe d'écartement 328 le long de la tige comme cela est illustré à la figure 16. Lors de sa remontée axiale, l'organe d'écartement 328 glissent sur les parties inférieures d'extrémité 320 des branches 318, ce qui a pour effet de contraindre radialement et de serrer les branches 318 vers l'extérieur contre la paroi périphérique du canal d'évacuation 304. Ceci provoque le rapprochement des portions allongées 319 des branches de la tige 327. Dans cette position, le pli 322 et la portion supérieure d'actionnement 321 de chaque branche est en appui axialement contre la face inférieure de la paroi radiale supérieure 313 de la tête de drainage.Then, the rod 327 is rotated clockwise via its upper end, which has the effect of causing the spacer member 328 to rise axially along the rod as illustrated in figure 16 . During its axial ascent, the spacer member 328 slides on the lower end portions 320 of the branches 318, which has the effect of radially constraining and tightening the branches 318 towards the outside against the peripheral wall of the channel evacuation 304. This causes the approximation of the elongated portions 319 of the branches of the stem 327. In this position, the fold 322 and the upper actuating portion 321 of each branch bears axially against the lower face of the upper radial wall 313 of the drainage head.

Lors de la rotation la tige 327 dans le sens horaire, la remontée axiale de l'organe d'écartement 318 du côté de l'épaulement 310 de la tête de drainage s'effectue ici jusqu'à ce que l'organe d'écartement 318 et les parties inférieures d'extrémité 320 des branches 318 soient bloqués par une saillie 333 annulaire du conduit d'évacuation 305 qui s'étend radialement vers l'intérieur à partir du canal d'évacuation 304. Ceci correspond à une deuxième position intermédiaire d'assemblage.During the rotation of the rod 327 in the clockwise direction, the axial rise of the spacer member 318 on the side of the shoulder 310 of the drainage head takes place here until the spacer member 318 and the lower end portions 320 of the branches 318 are blocked by an annular projection 333 of the evacuation duct 305 which extends radially inwards from the evacuation channel 304. This corresponds to a second intermediate position assembly.

La contrainte radiale exercée sur les branches 318 par l'organe d'écartement 328 permet d'assurer le maintien de la tête de de drainage 306 en appui contre la surface extérieure 303a de la construction 302. Lors du serrage des branches 318 par l'organe d'écartement 328, il se produit une déformation élastique des parties inférieures d'extrémité 320 des branches contre le canal d'évacuation 304.The radial stress exerted on the branches 318 by the spacer member 328 makes it possible to ensure that the drainage head 306 is held in abutment against the outer surface 303a of the construction 302. When the branches 318 are tightened by the spacer 328, there is an elastic deformation of the lower end parts 320 of the branches against the evacuation channel 304.

Lors de l'entrainement en rotation de la tige 327 dans le sens horaire, celle-ci coulisse aussi axialement à l'intérieur de la tête de drainage par coopération avec le filetage de la paroi radiale supérieure 313 de celle-ci. La platine 330 de compression coulisse axialement conjointement avec la tige 327 en restant axialement à distance du joint d'étanchéité 311. Les branches 318 bloquent la rotation de la platine lors du coulissement.When the rod 327 is driven in rotation in the clockwise direction, the latter also slides axially inside the drainage head by cooperating with the threading of the upper radial wall 313 thereof. The compression plate 330 slides axially together with the rod 327 while remaining axially at a distance from the seal 311. The branches 318 block the rotation of the plate during sliding.

Ensuite, à partir de la position bloquée de l'organe d'écartement 318 illustrée à la figure 16, lorsqu'on poursuit l'entrainement en rotation la tige 327 dans le sens horaire, celle-ci coulisse jusqu'à ce que la platine 330 de compression vienne axialement en appui contre le joint d'étanchéité 311 comme cela est illustré à la figure 17.Then, from the locked position of the spacer 318 illustrated in figure 16 , when the rotational drive of the rod 327 is continued in the clockwise direction, the latter slides until the compression plate 330 comes to bear axially against the seal 311 as illustrated in FIG. figure 17 .

Ceci permet d'assurer un bon plaquage axial de la tête de drainage 306 contre la surface extérieure de la construction 302. Lors de la mise en pression, on obtient ainsi une compression axiale du joint 311 entre la tête de drainage 306 et le la surface extérieure de la construction 302.This makes it possible to ensure good axial pressing of the drainage head 306 against the exterior surface of the construction 302. During pressurization, an axial compression of the gasket 311 is thus obtained between the drainage head 306 and the surface. exterior of building 302.
