Description

La présente invention concerne un appareil d'application d'un produit d'étanchement de joints ou de fissures, notamment sur les revêtements routiers.The present invention relates to an apparatus for applying a joint or crack sealant, in particular to road surfaces.

Les revêtements en question pourront être par exemple du type hydrocarboné ou du type à base de béton hydraulique, et les joints qu'il convient d'étancher pourront être notamment les joints séparant ordinairement, à des intervalles réguliers, deux éléments voisins du revêtement en béton. Quant aux fissures qu'il convient de boucher, il pourra s'agir de celles qui prennent naissance, notamment sur les revêtements hydrocarbonés, du fait des contraintes de dilatation ou de contraction engendrées dans le revêtement par des variations de température, mouvements du sol ou autres facteurs.The coatings in question may for example be of the hydrocarbon type or of the hydraulic concrete type, and the joints which should be sealed may be in particular the joints ordinarily separating, at regular intervals, two elements neighboring the concrete coating. . As for the cracks that should be plugged, they may be those that arise, especially on hydrocarbon coatings, due to the expansion or contraction constraints generated in the coating by temperature variations, ground movements or other factors.

Pour ce qui est du produit d'étanchement, il pourra s'agir de tout produit connu destiné à cet usage, par exemple de produits à base de bitume ou de goudron en mélange avec des élastomères, et de produits posés à chaud ou à froid, mais notamment de produits chauds dont la température au moment de l'application pourra être - pour fixer les idées - de l'ordre de 250° C au maximum, température que devra être comprise dans une fourchette d'environ 30° C.As regards the sealant, it may be any known product intended for this use, for example products based on bitumen or tar mixed with elastomers, and products applied hot or cold , but especially hot products whose temperature at the time of application may be - to fix ideas - of the order of 250 ° C maximum, temperature which should be within a range of about 30 ° C.

On comprend en tout cas que les produits d'étanchement ont pour fonction principale d'assurer une bonne étanchéité et de présenter une bonne élasticité dans les joints ou fissures à combler.It is understood in any case that the main function of sealing products is to ensure good sealing and to present good elasticity in the joints or cracks to be filled.

L'invention concerne plus particulièrement un appareil d'application d'un produit d'étanchement de joints ou de fissures, notamment sur les revêtements routiers, comportant une buse d'injection de produit reliée à une source de produit d'étanchement sous pression et à température adéquate portée par un appareillage automoteur ou remorqué annexe, par une conduite souple pourvue d'une chemise extérieure dans laquelle peut circuler un fluide thermorégulé de maintien en température dudit produit; des poignées permettant à un opérateur marchant sur le sol de guider et d'amener ladite buse, soit en position abaissée pour laquelle son orifice débouche à proximité immédiate du revêtement, soit en position relevée; une vanne de réglage du débit d'arrivée du produit à ladite buse, et un organe de commande de ladite vanne.The invention relates more particularly to an apparatus for applying a sealant to joints or cracks, in particular on road surfaces, comprising a product injection nozzle connected to a source of sealant under pressure and at an appropriate temperature carried by self-propelled or towed auxiliary equipment, by a flexible pipe provided with an outer jacket in which a thermoregulated fluid for maintaining the temperature of said product can circulate; handles allowing an operator walking on the ground to guide and bring said nozzle, either in the lowered position for which its orifice opens out in the immediate vicinity of the covering, or in the raised position; a valve for adjusting the flow rate of the product arriving at said nozzle, and a control member for said valve.

Un appareil de ce type général est connu par le US-A-2 802 601, mais il est conçu d'une façon qui le rend difficile à manoeuvrer, notamment du fait qu'en service il porte sur le revêtement par l'intermédiaire de patins de guidage disposés de part et d'autre de la buse et destinés à frotter sur le revêtement de chaque côté de la fissure à combler. Cette disposition en rend l'usage rapidement fatigant pour l'opérateur. En outre, lorsque celui-ci, après avoir réparé une zone du revêtement, doit franchir une zone saine pour se rendre en une zone présentant d'autres crevasses ou fissures à combler, il est pratiquement contraint, du fait de cette conception particulière de l'appareil, de remettre celuici provisoirement en place sur le véhicule automoteur ou remorqué qui porte le réservoir de produit et de rebobiner le tuyau, ce qui complique encore l'utilisation de l'appareil et est la cause d'une perte de temps considérable.An apparatus of this general type is known from US-A-2 802 601, but it is designed in a way which makes it difficult to operate, in particular because in service it relates to the coating by means of guide pads arranged on either side of the nozzle and intended to rub on the coating on each side of the crack to be filled. This arrangement makes it quickly tiring for the operator. In addition, when the latter, after repairing an area of the coating, must cross a healthy area to reach an area with other crevices or cracks to be filled, it is practically constrained, because of this particular design of the 'device, put it temporarily in place on the self-propelled or towed vehicle that carries the product tank and rewind the hose, which further complicates the use of the device and is the cause of a considerable loss of time.

En outre, il est à noter que cet appareil ne comporte pas de moyens de raclage, pour rendre la surface du joint unie et la mettre de niveau avec la surface du revêtement, ce qui est un autre grave inconvénient.In addition, it should be noted that this device does not include scraping means, to make the surface of the joint united and to level it with the surface of the coating, which is another serious drawback.

Le US-A-3 841 527 décrit un appareil du même type général, mais ne comportant aucun moyen d'appui sur le revêtement, permettant à l'opérateur d'ajuster avec précision la position de la buse d'injection du produit, qui est directement tenue à la main.US-A-3 841 527 describes a device of the same general type, but having no means of pressing on the coating, allowing the operator to precisely adjust the position of the product injection nozzle, which is directly held by hand.

Le US-A-3 050 260 décrit un appareil destiné au traçage de bandes de marquage peintes sur les revêtements routiers, et non pas un appareil de bouchage de fissures. Un tel appareil ne comporte pas de sabot de raclage, et la buse de sortie du produit est éloignée du sol, ce qui la rend tout à fait inapte à la distribution d'un produit d'étanchement de fissures.US-A-3 050 260 describes a device intended for tracing painted marking strips on road surfaces, and not a device for plugging cracks. Such an apparatus does not have a scraper shoe, and the product outlet nozzle is remote from the ground, which makes it completely unsuitable for dispensing a crack sealant.

Le US-A-2420410 décrit un appareil de bouchage de fissures à sabot racleur, mais la buse de distribution du produit est solidaire du véhicule portant le réservoir, ce qui rend l'appareil de distribution proprement dit (la buse et ses accessoires) extrêmement peu maniable, notamment en direction horizontale; ceci constitue un grave inconvénient lorsque l'on doit boucher des fissures ou lézardes non linéaires, comme c'est fréquemment le cas.US-A-2420410 describes a device for plugging cracks with a scraper shoe, but the product dispensing nozzle is integral with the vehicle carrying the tank, which makes the dispensing device itself (the nozzle and its accessories) extremely difficult to handle, especially in the horizontal direction; this is a serious drawback when it is necessary to plug non-linear cracks or cracks, as is frequently the case.

Le US-A-1 990 545 décrit un appareil présentant les mêmes inconvénients que le précédent, pour ce qui est de la précision; la buse de sortie est associée à un racleur, mais il s'agit ici encore d'un appareil de marquage, et non pas d'un appareil de bouchage de fissures.US-A-1 990 545 describes an apparatus having the same drawbacks as the previous one, with regard to precision; the outlet nozzle is associated with a scraper, but here again it is a marking device, and not a device for plugging cracks.

Le US-A-1 733 841 décrit un appareil de bouchage de fissures à sabot égalisateur, mais c'est cet appareil lui-même qui sert également de véhicule de transport du produit, puisqu'il porte les réservoirs. Cette disposition rend l'appareil lourd, encombrant et d'un maniement délicat et fatigant pour l'opérateur.US-A-1,733,841 describes a device for plugging cracks with an equalizing shoe, but it is this device itself which also serves as a vehicle for transporting the product, since it carries the tanks. This arrangement makes the device heavy, bulky and a delicate and tiring handling for the operator.

Le US-A-1 924 636 décrit un appareil du même type général que le précédent, mais sans dispositif égalisateur.US-A-1,924,636 describes a device of the same general type as the previous one, but without an equalizing device.

Le US-A-2530777 décrit un appareil de bouchage de fissures dans lequel, là encore, la buse distributrice est solidaire du véhicule portant le réservoir de produit; l'opérateur, lui aussi, est porté par ce véhicule. Ces dispositions rendent le maniement de la buse peu commode et peu précis.US-A-2530777 describes a device for plugging cracks in which, again, the dispensing nozzle is secured to the vehicle carrying the product reservoir; the operator, too, is carried by this vehicle. These provisions make the handling of the nozzle inconvenient and imprecise.

Le US-A-3 206 125 décrit un appareillage pour le bouchage de fissures qui présente le même genre d'inconvénient que celui du US-A-3 841 527.US-A-3 206 125 describes an apparatus for plugging cracks which has the same kind of drawback as that of US-A-3 841 527.

Le US-A-2 161 488 décrit un appareillage porté par un véhicule, présentant globalement les mêmes inconvénients que celui du US-A-2 530 777.US-A-2,161,488 describes an apparatus carried by a vehicle, generally having the same drawbacks as that of US-A-2,530,777.

Enfin, le US-A-1750104 décrit encore un appareil de bouchage de fissures portant le réservoir, et présentant le même genre d'inconvénients que, par exemple, celui du US-A-1 924 636.Finally, US-A-1750104 further describes a device for filling cracks carrying the reservoir, and having the same kind of drawbacks as, for example, that of US-A-1,924,636.

Le but de la présente invention est de remédier à tous ces inconvénients et lacunes de la technique antérieure, et d'obtenir un appareil du type général décrit au début, mais qui en outre soit particulièrement leger et maniable, permette facilement un bouchage précis des fissures, sans fatigue particulière pour l'opérateur et sans temps morts, et qui, de plus, permette d'obtenier des joints lisses et parfaitement de niveau avec le revêtement à réparer.The object of the present invention is to remedy all of these drawbacks and shortcomings of the prior art, and to obtain an apparatus of the general type described at the start, but which, moreover, is particularly light and handy, easily allows precise filling of cracks. , without particular fatigue for the operator and without downtime, and which, moreover, makes it possible to obtain smooth joints and perfectly level with the coating to be repaired.

Ces buts sont obtenus par un appareil du type général défini au début et qui, conformément à l'invention, est caractérisé en ce qu'il est réalisé essentiellement sous la forme d'un châssis portant au moins une roue de roulement située à l'avant ou à l'arrière, et propre à rouler sur le revêtement et, en ses deux extrémités opposées, respectivement les poignées et la buse d'injection, l'extrémité du châssis qui porte la buse d'injection présentant en plan sensiblement la forme d'un triangle ouvert vers l'avant - eu égard au sens d'avancement normal prévu pour l'appareil - et dans l'angle postérieur duquel se situe ladite buse, cette partie en triangle étant prévue pour que son bord inférieur porte sur iedit revétement lorsque la buse d'injection occupe la position abaissée précitée, et forme ainsi un sabot racleur.These objects are obtained by an apparatus of the general type defined at the start and which, according to the invention, is characterized in that it is produced essentially in the form of a chassis carrying at least one rolling wheel located at the front or rear, and suitable for rolling on the covering and, at its two opposite ends, respectively the handles and the injection nozzle, the end of the frame which carries the injection nozzle having in plan substantially the shape of a triangle open towards the front - having regard to the normal direction of advance provided for the device - and in the posterior angle from which said nozzle is situated, this triangle part being provided so that its lower edge bears on iedit coating when the injection nozzle occupies the aforementioned lowered position, and thus forms a scraper shoe.

Cet appareil très maniable permettra facilement à l'opérateur de positionner exactement la buse d'injection au-dessus du joint ou de la fissure à combler et d'en suivre précisément le trajet, de même qu'il lui permettra de commander immédiatement i'arrivée du produit d'étanchement à la buse ou l'interruption du débit, selon les besoins. En outre, la roue pourra servir de béquille lorsque l'appareil ne sera plus utilisé.This very handy device will allow the operator to easily position the injection nozzle exactly over the joint or crack to be filled and to follow its path precisely, just as it will allow him to immediately order i ' arrival of the sealant at the nozzle or interruption of the flow, as required. In addition, the wheel can be used as a stand when the device is no longer in use.

Quant à la disposition, en forme de triangle ouvert vers l'avant, du sabot racleur, elle permettra à l'utilisateur une observation facile de la superposition de la buse d'injection et du joint ou fissure à combler, et en outre le produit éventuellement en excès sera raclé et ramené dans ledit joint ou fissure, ce qui permettra d'éviter la présence de bavures et bourrelets.As for the arrangement, in the shape of a triangle open towards the front, of the scraper shoe, it will allow the user an easy observation of the superposition of the injection nozzle and the joint or crack to be filled, and in addition the product. possibly in excess will be scraped and brought back into said joint or crack, which will avoid the presence of burrs and beads.

Quant à l'organe de commande de la vanne de réglage du débit d'arrivée du produit à la buse d'injection, il pourra avantageusement être porté par l'une des poignées précitées de l'appareil et être relié à la vanne par un câble du genre Bowden dont la traction est adaptée à ouvrir la vanne, la fermeture de celle-ci étant aussurée par un ressort de rappel.As for the control member of the valve for adjusting the flow rate of arrival of the product at the injection nozzle, it can advantageously be carried by one of the aforementioned handles of the device and be connected to the valve by a Bowden type cable, the traction of which is adapted to open the valve, the closing thereof being also ensured by a return spring.

Le châssis de l'appareil pourra porter en outre, devant la buse - eu égard au sens d'avancement normal pour l'appareil - une buse de soufflage d'air comprimé dont le débit peut éventuellement être commandé à partir de l'autre poignée, avec éventuellement aussi, derrière la buse, des moyens de projection de gravillons ou analogues.The chassis of the device can also carry, in front of the nozzle - having regard to the normal direction of advance for the device - a compressed air blowing nozzle, the flow of which can optionally be controlled from the other handle. , with possibly also, behind the nozzle, means for projecting gravel or the like.

Grâce à cette disposition, on pourra effectuer un prénettoyage du joint ou de la fissure à combler, et éventuellement la pose de gravillons ou analogues, préchauffés ou non, sur le produit.Thanks to this arrangement, it will be possible to pre-clean the joint or the crack to be filled, and possibly the laying of gravel or the like, preheated or not, on the product.

Enfin, un perfectionnement de l'appareil pourrait encore consister en ce que ledit châssis porte en outre un moteur, de préférence hydraulique, accouplé à ladite roue, ou à au moins l'une des roues lorsque le châssis en porte plusieurs.Finally, an improvement of the device could also consist in that said chassis further carries a motor, preferably hydraulic, coupled to said wheel, or to at least one of the wheels when the chassis carries several.

Un mode d'exécution de l'invention va maintenant être décrit à titre d'exemple nullement limitatif, avec référence à la figure unique du dessin annexé.An embodiment of the invention will now be described by way of non-limiting example, with reference to the single figure of the accompanying drawing.

Dans cette figure, le châssis de l'appareil. à été référencé globalement en 1. Ce châssis peut être constitué de fers plats soudés, référencés en 2, entretoisés en 3, auxquels est fixée, par l'intermédiaire d'une chappe 4 et de tiges soudées 5, une oue de roulement 6. L'extrémité supérieure du châssis 1 porte des poignées soudées 7, et son extrémité opposée est conformée en sabot racleur 8 ayant la forme générale d'un triangle ouvert vers l'avant, eu égard au sens de déplacement normal de l'appareil, représenté par la flèche F.In this figure, the chassis of the device. has been generally referenced in 1. This chassis can be made up of welded flat bars, referenced in 2, braced in 3, to which is fixed, by means of a clevis 4 and welded rods 5, a rolling eye 6. The upper end of the chassis 1 carries welded handles 7, and its opposite end is shaped as a scraper shoe 8 having the general shape of a triangle open towards the front, having regard to the normal direction of movement of the device, shown by arrow F.

Dans l'angle de sommet dudit sabot racleur 8 est fixée une buse d'injection 9, dont l'orifice de sortie débouche à proximité immédiate de la surface du revêtement 10 lorsque l'appareil occupe la position représentée sur la figure, pour laquelle ledit sabot racleur 8 porte sur le revêtement.In the apex angle of said scraper shoe 8 is fixed an injection nozzle 9, the outlet of which opens in the immediate vicinity of the surface of the coating 10 when the apparatus occupies the position shown in the figure, for which said scraper shoe 8 carries on the coating.

La buse d'injection 9 est reliée à une source de produit d'étanchement sous pression et à température adéquate (non représentée mais portée par exemple par un appareillage automoteur annexe), par l'intermédiaire d'une vanne de réglage de débit 11 et d'une conduite souple d'alimentation 12.The injection nozzle 9 is connected to a source of sealant under pressure and at an appropriate temperature (not shown but carried for example by a self-propelled auxiliary device), by means of a flow control valve 11 and a flexible supply line 12.

La conduite 12 est pourvue d'une chemise extérieure dans laquelle, sous l'action d'une pompe portée également par ledit appareillage automoteur, peut circuler un fluide thermorégulé de maintien en température du produit d'étanchement, lequel fluide peut être constitué par exemple par de l'huile.Line 12 is provided with an outer jacket in which, under the action of a pump also carried by said self-propelled apparatus, can circulate a thermoregulated fluid for maintaining the temperature of the sealant, which fluid can be constituted for example with oil.

La conduite de retour d'huile a été désignée en 13. Les conduites 12 et 13 sont convenablement calorifugées, par exemple + l'amiante.The oil return line has been designated at 13. The lines 12 and 13 are suitably insulated, for example + asbestos.

La commande du débit de la vanne de réglage 11 peut être effectuée à partir d'une manette de commande 14 portée par l'une des poignées 7 et reliée par un câble du genre Bowden 15 au levier d'ouverture ou de fermeture 16 de la vanne de réglage 11. L'ouverture de la vanne étant commandée par une pression exercée sur la manette 14, sa fermeture peut être aussurée par un ressort de rappel 17 tendu entre le levier 16 et un support soudé 18.The flow control of the regulating valve 11 can be carried out from a control handle 14 carried by one of the handles 7 and connected by a cable of the Bowden type 15 to the opening or closing lever 16 of the adjusting valve 11. The opening of the valve being controlled by a pressure exerted on the lever 14, its closing can be ensured by a return spring 17 stretched between the lever 16 and a welded support 18.

Par ailleurs, une autre entretoise 19 du sabot racleur 8 porte une buse de soufflage d'air comprimé 20 reliée, par l'intermédiaire d'une vanne de réglage de débit 21 et d'une conduite souple 22, à une source d'air comprimé également portée par ledit appareillage automoteur annexe.Furthermore, another spacer 19 of the scraper shoe 8 carries a compressed air blowing nozzle 20 connected, via a flow control valve 21 and a flexible pipe 22, to an air source tablet also carried by said self-propelled auxiliary equipment.

De même que pour la vanne 11, le réglage de l'ouverture ou de la fermeture de la vanne 21 peut être assuré par une autre manette de commande 23, portée par l'autre pignée 7 et reliée, par un câble de genre Bowden 24, à un levier 25 de la vanne, la fermeture de la vanne étant assurée par un autre ressort de rappel, référencé en 26.As for the valve 11, the adjustment of the opening or the closing of the valve 21 can be ensured by another control lever 23, carried by the other handle 7 and connected, by a Bowden type cable 24 , to a lever 25 of the valve, the valve being closed by another return spring, referenced at 26.

L'appareil pourrait encore porter, derrière la buse 9, des moyens de projection de gravillons ou analogues, préchauffés ou non, de même que le châssis pourrait porter en outre un moteur, de préférence hydraulique, accouplé à la roue 6.The apparatus could also carry, behind the nozzle 9, means for projecting gravel or the like, preheated or not, just as the chassis could also carry a motor, preferably hydraulic, coupled to the wheel 6.

Enfin, on a référencé en 27 un joint à combler, situé par exemple entre deux dalles de béton, et en 28 la surface supérieure du joint effectué.Finally, reference is made at 27 to a joint to be filled, situated for example between two concrete slabs, and at 28 the upper surface of the joint made.

L'opérateur, saisissant l'appareil par les poignées 7, et marchant à reculons dans le sens de la flèche F, pourra facilement observer la superposition de la buse d'injection 9 et du joint ou de la fissure à combler 27, et aussurer un remplissage correct du joint en réglant convenablement la pression exercée sur la manette de réglage 14, commandant le débit d'arrivée du produit d'étanchement sous pression à la buse 9, et éventuellement en réglant la vitesse de sa marche, ceci pour éviter un excès d'arrivée de produit à l'intérieur du sabot racleur 8 ou, au contraire, un manque de produit.The operator, grasping the apparatus by the handles 7, and walking backwards in the direction of the arrow F, will be able to easily observe the superposition of the injection nozzle 9 and of the joint or of the crack to be filled 27, and also correct filling of the joint by appropriately adjusting the pressure exerted on the adjusting handle 14, controlling the flow of arrival of the sealant under pressure at the nozzle 9, and possibly by adjusting the speed of its operation, this to avoid excess product arrival inside the scraper shoe 8 or, on the contrary, a lack of product.

Le sabot 8 raclant le revêtement, on obitiendra toujours un joint 28 exactement de niveau avec le revêtement 10.The shoe 8 scraping the coating, we will always obtain a seal 28 exactly level with the coating 10.

En cas de besoin, une pression exercée sur la manette de commande 23 permettra d'effectuer un nettoyage du joint 27 ou fissure analogue à combler, avant injection du produit d'étanchement.If necessary, a pressure exerted on the control handle 23 will allow cleaning of the seal 27 or similar crack to be filled, before injection of the sealant.

Il est à noter d'autre part que la roue de roulement 6 peut aussi servir de béquille, lorsque l'appareil n'est pas utilisé.It should also be noted that the running wheel 6 can also serve as a stand, when the device is not in use.

Enfin, lorsque l'opérateur désire déplacer l'appareil d'un emplacement de travail à un autre, il lui suffit, par une légère pression exercée vers le bas sur les poignées 7, de faire pivoter l'appareil pour décoller le sabot racleur 8 et lui faire occuper une position relevée pour laquelle celui-ci n'est plus en contact avec le revêtement 10.Finally, when the operator wishes to move the appliance from one working place to another, it suffices for him, by light pressure exerted downwards on the handles 7, to pivot the appliance to take off the scraper shoe 8 and make it occupy a raised position for which the latter is no longer in contact with the covering 10.

Comme il va de soi, et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus spécialment envisagés; elle en embrasse, au contraire, toutes les variantes.As goes without saying, and as it already follows from the foregoing, the invention is in no way limited to those of its modes of application and embodiments which have been more specifically envisaged; on the contrary, it embraces all its variants.

Ainsi, par rapport au mode d'exécution nullement limitatif qui vient d'être décrit, on pourrait envisager une disposition assez différente des éléments essentiels de l'appareil: par exemple, le sabot racleur 8 pourrait être ouvert dans le sens inverse, c'est-à-dire du côté opposé au sens indiqué par la flèche F, l'appareil étant alors prévu pour se déplacer dans ce sens inverse.Thus, compared to the non-limiting embodiment which has just been described, one could envisage a provision quite different from the essential elements of the apparatus: for example, the scraper shoe 8 could be opened in the opposite direction, it that is to say on the side opposite to the direction indicated by the arrow F, the device then being designed to move in this opposite direction.

Dans ce cas, la buse de soufflage d'air comprimé 20 serait placée devant la buse d'injection de produit d'étanchement 9, et au contraire la buse de projection de gravillons ou analogues, préchauffés ou non, serait disposée derrière la buse 9 (pratiquement à l'emplacement que la buse 20 occupe actuellement dans la figure).In this case, the compressed air blowing nozzle 20 would be placed in front of the sealant injection nozzle 9, and on the contrary the spray nozzle for gravel or the like, preheated or not, would be placed behind the nozzle 9 (practically at the location that the nozzle 20 currently occupies in the figure).

Cette disposition permettrait de conférer un rôle supplémentaire à la roue de roulement 6, qui consisterait à produire l'enfoncement des gravillons ou analogues dans la surface 28 du produit d'étanchement une fois posé. Pour ce faire, il suffirait par exemple de prévoir une roue 6 plus large que celle qui a été représentée à la figure, et métallique.This arrangement would make it possible to confer an additional role on the rolling wheel 6, which would consist in causing the gravel or the like to sink into the surface 28 of the sealant once it has been applied. To do this, it would suffice for example to provide a wheel 6 wider than that which has been shown in the figure, and metallic.
