Description

La présente invention a pour objet une barrière de sécurité pour ouvertures d'accès de bâtiments ou parties de bâtiments abritant des produits liquides dont on veut empêcher à tout prix l'échappement, même en cas d'accidents, ou de bâtiments dont on veut éviter, de manière garantie, l'inondation avec des liquides venant de l'extérieur.The subject of the present invention is a safety barrier for access openings to buildings or parts of buildings housing liquid products whose escape is to be prevented at all costs, even in the event of accidents, or to buildings which are to be avoided. , guaranteed, flooding with liquids coming from outside.

Le but de l'invention est une barrière qui est complètement escamotée pendant le temps où le bâtiment est ouvert pour le déchargement ou le chargement de produits qui y sont emmagasinés, mais peut être mise en place instantanément dès qu'un accident survient. L'escamotage de la barrière doit permettre que des engins équipés de roues à faible diamètre (exemple: chariots de levage) peuvent franchir facilement le seuil de l'ouverture d'accès où est installé la barrière. La barrière doit être de sécurité. Sa mise en place doit être assurée, même en cas de dysfonctionnement de certaines parties de son mécanisme.The object of the invention is a barrier which is completely retracted during the time when the building is open for the unloading or the loading of products which are stored there, but can be put in place instantly as soon as an accident occurs. The retraction of the barrier must allow machines equipped with small diameter wheels (example: lifting carriages) to easily cross the threshold of the access opening where the barrier is installed. The barrier must be of security. Its installation must be ensured, even in the event of malfunction of certain parts of its mechanism.

La barrière de sécurité suivant l'invention est caractérisée en ce que dans le sol du seuil d'accès d'un bâtiment ou partie d'un bâtiment est logé, dans une fosse, une jupe souple repliée, reliée de manière étanche au fond et aux parois latérales de la fosse jusqu'à une hauteur déterminée, en ce que cette jupe, à l'état repliée, est recouverte par une taque passerelle basculante disposée horizontalement, et masquant la fosse, en ce que cette taque basculante est actionnée par un système de levage opéré au moyen d'un dispositif de commande pour la basculer en position verticale, et en ce que l'arète supérieure de la jupe est reliée à un dispositif de levage actionné simultanément avec le basculement de la taque en position verticale.The safety barrier according to the invention is characterized in that in the ground of the access threshold of a building or part of a building is housed, in a pit, a flexible folded skirt, tightly connected to the bottom and to the side walls of the pit up to a determined height, in that this skirt, in the folded state, is covered by a tilting gate plate disposed horizontally, and masking the pit, in that this tilting plate is actuated by a lifting system operated by means of a control device for tilting it in the vertical position, and in that the upper edge of the skirt is connected to a lifting device actuated simultaneously with the tilting of the plate in the vertical position.

De préférence, suivant l'invention, la jupe souple est constituée par un ensemble de boîtiers souples, gonflables, reliés via au moins une vanne à un réservoir de fluide sous pression.Preferably, according to the invention, the flexible skirt is constituted by a set of flexible, inflatable boxes, connected via at least one valve to a reservoir of pressurized fluid.

L'invention est expliquée ci-dessous par rapport à un exemple d'exécution préféré et une variante simplifiée en se référant au dessin annexé. La figure 1 de ce dessin représente une vue en perspective, partiellement coupée, de la version préférée. La figure 2 est une même vue en perspective, partiellement coupée d'une version simplifiée de l'invention. La figure 3 est une vue en plan d'une autre variante de l'invention. Des références identiques dans les trois figures désignent des mêmes éléments.The invention is explained below with respect to a preferred embodiment and a simplified variant with reference to the accompanying drawing. Figure 1 of this drawing shows a perspective view, partially cut away, of the preferred version. Figure 2 is the same perspective view, partially cut away from a simplified version of the invention. Figure 3 is a plan view of another variant of the invention. Identical references in the three figures designate the same elements.

A la figure 1, une barrière suivant l'invention est installée à l'intérieur d'une porte d'accès d'un bâtiment dont on voit un des montants 1 et le linteau 2 coupé près du montant. Le montant est équipé de gonds 3 pour une porte, non représentée. Dans le seuil de la porte, une fosse 4 est recouverte par une taque passerelle basculante 5 au niveau du sol du bâtiment. La taque 5 peut pivoter autour d'un axe 6 de la position horizontale, montrée à la figure 2, dans la position verticale, montrée à la figure 1. Lorsque la taque 5 se trouve en position horizontale, elle livre un passage sans encombre, même à des engins à roues de diamètre très petits.In FIG. 1, a barrier according to the invention is installed inside an access door of a building of which we see one of the uprights 1 and the lintel 2 cut near the upright. The upright is fitted with hinges 3 for a door, not shown. In the threshold of the door, a pit 4 is covered by a tilting gate plate 5 at ground level of the building. The plate 5 can pivot around an axis 6 from the horizontal position, shown in FIG. 2, in the vertical position, shown in FIG. 1. When the plate 5 is in the horizontal position, it delivers a smooth passage, even to vehicles with very small diameter wheels.

Une jupe constituée par un ensemble de boîtiers souples 7, repliables et gonflables est fixée de manière étanche au fond de la fosse 3, et jusqu'à une hauteur déterminée, aux parois latérales de la fosse qui sont aussi les parois latérales de part et d'autre de la porte d'accès. La fixation est réalisée, par exemple, au moyen de méplats 8 vissés à travers la jupe sur le fond et les parois latérales de la fosse. La dite hauteur déterminée est, en l'occurrence, environ égale à la hauteur de la taque passerelle levée en position verticale, montrée à la figure 1. De ce fait, un certain espace est réservé entre les extrémités latérales de la taque basculante 5 et les parois latérales où sont fixés les extrémités des boîtiers souples 7. Lorsque la taque basculante 5 se trouve en position horizontale (figure 2), le dessus de la jupe descend en oblique, de l'extrémité supérieure de l'endroit où elle est fixée à une paroi latérale, vers le niveau de la taque 5 à l'endroit de l'extrémité latérale de cette dernière. Pour le reste, la jupe se trouve dégonflée dans le fond de la fosse 2 recouverte par la taque 5. Les boîtiers souples 7 de la jupe sont représentés à l'état gonflé à la figure 1.A skirt constituted by a set of flexible, inflatable and foldable housings 7 is tightly fixed to the bottom of the pit 3, and up to a determined height, to the side walls of the pit which are also the side walls on either side. other of the access door. The fixing is carried out, for example, by means of flats 8 screwed through the skirt on the bottom and the side walls of the pit. Said determined height is, in this case, approximately equal to the height of the gangway plate raised in vertical position, shown in FIG. 1. Therefore, a certain space is reserved between the lateral ends of the tilting plate 5 and the side walls where the ends of the flexible housings are fixed 7. When the tilting plate 5 is in a horizontal position (FIG. 2), the top of the skirt descends obliquely from the upper end of the place where it is fixed to a side wall, towards the level of the plate 5 at the location of the lateral end of the latter. For the rest, the skirt is deflated in the bottom of the pit 2 covered by the plate 5. The flexible housings 7 of the skirt are shown in the inflated state in FIG. 1.

Si la descente en oblique de ta jupe vers le niveau de la taque passerelle 5 risque d'être trop raide, il est possible de prévoir une fosse coudée telle que représentée en 4' à la figure 3. Selon cette solution, on donne aux boîtiers 7 de la jupe également une forme coudée.If the oblique descent of your skirt towards the level of the bridge plate 5 risks being too steep, it is possible to provide an angled pit as shown in 4 'in FIG. 3. According to this solution, the boxes are given 7 of the skirt also has a bent shape.

La taque passerelle 5 est reliée à un système de levage constitué par un câble ou une chaîne 9 fixée en deux endroits rapprochés à une broche solidaire de extrémité de l'arète libre de la taque 5 et passant par deux poulies fixes 10 et 11 et une poulie mobile 12 supportant un contrepoids 13. Les deux parties du câble ou de la chaîne 9 entre les poulies fixes et la poulie mobile passent chacune à travers un dispositif à électro-aimant de blocage respectivement 14 et 15. Le dispositif 14 est débloqué par un signal de commande de levée de la barrière. Ce signal de commande est envoyé à partir d'un dispositif, non représenté. Le dispositif 15 est débloqué en l'absence de tension électrique. Lorsqu'un des dispositifs à électro-aimant 14 ou 15 est débloqué, le contrepoids 13 descend et lève la taque basculante 5 en position verticale. Ceci est représenté à la figure 1. Pour descendre la taque 5 dans la position horizontale, un système d'armement manuel ou autre, non représenté, peut être prévu. Le système de levage décrit peut être remplacé par tout autre qui assure une sécurité de fonctionnement identique ou meilleure.The gateway plate 5 is connected to a lifting system constituted by a cable or chain 9 fixed in two places close to a pin secured to the end of the free edge of the plate 5 and passing through two fixed pulleys 10 and 11 and a movable pulley 12 supporting a counterweight 13. The two parts of the cable or chain 9 between the fixed pulleys and the movable pulley each pass through a device with locking electromagnet 14 and 15 respectively. The device 14 is released by a control signal of lifting the barrier. This control signal is sent from a device, not shown. The device 15 is released in the absence of electrical voltage. When one of the electromagnet devices 14 or 15 is released, the counterweight 13 descends and lifts the tilting plate 5 in the vertical position. This is shown in Figure 1. To lower the plate 5 in the horizontal position, a manual or other arming system, not shown, can be provided. The lifting system described can be replaced by any other which provides the same or better operating safety.

En même temps qu'un des dispositifs à électro-aimant 14 ou 15 est actionné, une vanne 16 s'ouvre et met en communication l'intérieur des boîtiers souples 7 avec un réservoir à fluide sous pression 17. Ce réservoir 17 peut être un réservoir à air comprimé alimenté par un compresseur, non représenté. Suivant une autre possibilité, ce réservoir 17 peut être un réservoir d'eau, placé plus haut que la hauteur maximale du barrage. La vanne 16 peut être une vanne à trois voies mettant l'intérieur des boîtiers souples 7 soit en communication avec un conduit de détente où d'écoulement, non représenté, soit en communication avec le réservoir 17. La commande de la vanne 16 peut être une commande simple qui est actionnée en cas d'accident ou une commande du même principe que la commande du système de levage de la taque 5, à savoir, la vanne est actionnée et en cas d'accident et en cas d'absence de tension électrique.At the same time as one of the electromagnet devices 14 or 15 is actuated, a valve 16 opens and puts the interior of the flexible housings 7 into communication with a reservoir for pressurized fluid 17. This reservoir 17 can be a compressed air tank supplied by a compressor, not shown. According to another possibility, this reservoir 17 can be a water reservoir, placed higher than the maximum height of the dam. The valve 16 can be a three-way valve putting the interior of the flexible housings 7 either in communication with an expansion or flow conduit, not shown, or in communication with the reservoir 17. The control of the valve 16 can be a simple control which is actuated in the event of an accident or a control on the same principle as the control of the lifting system of the plate 5, namely, the valve is actuated both in the event of an accident and in the event of no voltage electric.

Le fonctionnement du barrage est le suivant: Dès qu'un accident se produit à l'intérieur du bâtiment et que du liquide y emmagasiné dans des réceptacles (bouteilles, fûts, containers, etc.) se répand sur le sol, le barrage est levé pour empêcher le liquide de sortir du bâtiment. La détection de ce phénomène peut se faire automatiquement au moyen de dispositifs de détection de présence de fluide, en soi connus. A ce moment, la taque 5 se lève et les boîtiers gonflables 7 se gonflent et forment un barrage étanche et efficace, ne laissant pas sortir le liquide du bâtiment. La hauteur maximale du barrage est atteint pratiquement instantanément. De préférence, cette hauteur est choisie telle qu'elle est capable de retenir tout le liquide qui peut s'écouler en cas d'un accident détruisant tous les réceptacles emmagasinés dans le bâtiment. En cas d'absence de tension électrique, par précaution, le barrage est levé également. Si lors de manoeuvres sous la porte, le système de levage de la taque 5 est endommagé, et ne fonctionne plus, la pression admise dans les boîtiers souples 7 est suffisante pour permettre de lever la taque 5 et de retenir ainsi le liquide répandu sur le sol du bâtiment.The functioning of the dam is as follows: As soon as an accident occurs inside the building and liquid stored therein in receptacles (bottles, drums, containers, etc.) spreads on the ground, the dam is lifted to prevent liquid from coming out of the building. The detection of this phenomenon can be done automatically by means of fluid presence detection devices, known per se. At this time, the plate 5 rises and the inflatable boxes 7 inflate and form a tight and effective barrier, not letting the liquid out of the building. The maximum height of the dam is reached almost instantly. Preferably, this height is chosen such that it is capable of retaining all the liquid that can flow in the event of an accident destroying all the receptacles stored in the building. If there is no electrical voltage, as a precaution, the barrier is also raised. If during operations under the door, the lifting system of the plate 5 is damaged, and no longer works, the pressure admitted into the flexible housings 7 is sufficient to allow the plate 5 to be lifted and thus retain the liquid spilled on the building floor.

Pour le cas où le système d'alimentation des boîtiers souples 7 en fluide sous pression tombe en panne, une sécurité supplémentaire est prévue. Un dispositif de levage de la jupe est actionné simultanément avec le basculement de la taque 5 en position verticale. Ce dispositif de levage peut être très simplement une liaison mécanique permanente de l'arète supérieure de la jupe 18 à l'arète libre de la taque basculante 5. Cette solution est montrée à la figure 2.In the event that the system for supplying the flexible housings 7 with pressurized fluid breaks down, additional security is provided. A device for lifting the skirt is actuated simultaneously with the tilting of the plate 5 in the vertical position. This lifting device can very simply be a permanent mechanical connection from the upper edge of the skirt 18 to the free edge of the tilting plate 5. This solution is shown in FIG. 2.

Une autre solution est montrée à la figure 1. Un élément élastique, par exemple un ressort ou une corde élastique 19 est tendue d'une paroi latérale à l'autre, parallèlement à la taque 5 et à la jupe. Les points de fixation de cet élément élastique sont disposés à une hauteur égale ou un peu supérieure à la hauteur maximale du barrage levé. Les endroits précis où a lieu la fixation de l'élément 19 sont choisis de telle manière que ce ressort ou corde élastique se place automatiquement à proximité de l'axe 6 de la taque 5 en position horizontale. Un tel résultat est atteint, si la fixation de la corde élastique 19 a lieu à proximité de l'intersection d'un plan vertical passant par l'axe 6 avec les parois latérales. En procédant de la sorte, le couple exercé par cet élément 19 sur la taque basculante 5 est très faible et ne contrarie pas la position horizontale de cette dernière.Another solution is shown in FIG. 1. An elastic element, for example a spring or an elastic cord 19 is stretched from one side wall to the other, parallel to the plate 5 and to the skirt. The fixing points of this elastic element are arranged at a height equal to or a little greater than the maximum height of the raised boom. The precise places where the element 19 is fixed are chosen so that this spring or elastic cord is automatically placed near the axis 6 of the plate 5 in a horizontal position. Such a result is achieved, if the fixing of the elastic cord 19 takes place near the intersection of a vertical plane passing through the axis 6 with the side walls. By doing so, the torque exerted by this element 19 on the tilting plate 5 is very low and does not interfere with the horizontal position of the latter.

Une troisième solution de réaliser un tel dispositif de levée de la jupe est de réaliser la jupe en un ensemble de boîtiers remplis de mousse légère et facilement déformable qui se dresse de soi-même dans la position du barrage levé. Ceci peut se faire aussi en parallèle avec des boîtiers gonflables au moyen d'un fluide sous pression.A third solution of making such a device for lifting the skirt is to make the skirt in a set of boxes filled with light and easily deformable foam which rises by itself in the position of the raised boom. This can also be done in parallel with inflatable boxes using a pressurized fluid.

A la figure 2, la jupe constituée par des boîtiers souples gonflables 7 est remplacée par une simple toile 18 en caoutchouc ou en un autre matériau souple et étanche. Cette toile 18 est fixée au sol et aux parois latérales de la fosse 4 d'une part, et à l'arète libre de la taque basculante 5 d'autre part. La fixation peut être fait au moyen de méplats 8, comme déjà décrit. De cette manière, La jupe 18 descend en direction oblique de l'endroit où elle est fixée à la paroi latérale vers l'extrémité latérale de la taque passerelle 5 en position horizontale et se trouve à l'état repliée en dessous de la taque 5.In FIG. 2, the skirt constituted by inflatable flexible boxes 7 is replaced by a simple canvas 18 made of rubber or of another flexible and waterproof material. This fabric 18 is fixed to the ground and to the side walls of the pit 4 on the one hand, and to the free edge of the tilting plate 5 on the other hand. The fixing can be done by means of flats 8, as already described. In this way, the skirt 18 descends in oblique direction from the place where it is fixed to the side wall towards the lateral end of the gangway plate 5 in a horizontal position and is in the folded state below the plate 5.

La variante suivant la figure 2 n'assure pas une sécurité de fonctionnement aussi grande que la variante selon la figure 1; elle peut donc être envisagée seulement dans des cas où les exigences de sécurité ne sont pas trop sévères.The variant according to Figure 2 does not provide as high operating safety as the variant according to Figure 1; it can therefore be considered only in cases where the security requirements are not too severe.

Si les boîtiers souples 7 sont actionnés par de l'eau, il est utile de doubler la jupe en boîtiers gonflables 7 d'une jupe 18 disposée côté intérieur du bâtiment pour éviter qu'en cas de fuite d'un des boîtiers de l'eau ne pénètre à l'intérieur du bâtiment.If the flexible boxes 7 are actuated by water, it is useful to double the skirt in inflatable boxes 7 with a skirt 18 disposed on the interior side of the building to prevent that in case of leakage of one of the boxes of the no water gets inside the building.

Si la barrière de sécurité est destinée à empêcher l'inondation d'un bâtiment par des liquides venant de l'extérieur, il est recommandé d'inverser le sens d'ouverture de la taque basculante 5 qui doit de préférence servir de dossier d'appui pour la jupe de retenue.If the safety barrier is intended to prevent the flooding of a building by liquids coming from outside, it is recommended to reverse the opening direction of the tilting plate 5 which should preferably serve as a backrest. support for the retaining skirt.
