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 température au moment de l'application pourra être - pour fixer les idées - de l'ordre de 250°C au maximum, température qui 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.

A l'heure actuelle, ces produits sont mis en oeuvre très souvent à la main à l'aide d'un genre de cuiller ou simplement par coulée sous l'effet de la gravité, dans une goulotte fixée à la sortie d'un fondoir; on utilise aussi quelquefois une lance.At present, these products are very often used by hand using a kind of spoon or simply by pouring under the effect of gravity, in a chute attached to the outlet of a melter ; sometimes a lance is also used.

Tous les procédés connus actuellement, de toute façon, sont d'une mise en oeuvre longue et fastidieuse, et ne permettent pas d'obtenir un remplissage des joints ou fissures avec un aspect superficiel qui soit convenable, et le produit coule fréquemment en dehors du joint ou de la fissure; il y a des bavures, et souvent des surépaisseurs rendant le revêtement peu confortable pour les usagers.All the methods currently known anyway, are of a long and tedious implementation, and do not allow filling of the joints or cracks with a suitable surface appearance, and the product frequently flows out of the joint or crack; there are burrs, and often extra thicknesses making the coating uncomfortable for users.

Le but de la présente invention est de remédier à tous ces inconvénients des procédés connus et, à cet effet, un appareil d'application d'un produit d'étanchement de joints ou de fissures, notamment sur les revêtements routiers, conforme à l'invention, est caractérisé en ce qu'il est constitué d'un châssis portant : une buse d'injection de produit, reliée à une source de produit d'étanchement sous pression et à température adéquate; des poignées permettant de guider ledit châssis 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 αmmande de ladite vanne.The object of the present invention is to remedy all these drawbacks of known methods and, to this end, an apparatus for applying a sealant for joints or cracks, in particular on road surfaces, in accordance with invention, is characterized in that it consists of a chassis carrying: a product injection nozzle, connected to a source of sealant under pressure and at an appropriate temperature; handles for guiding said frame and for bringing 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 of said valve.

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 l'arrivée du produit d'étanchement à la buse ou l'interruption du débit, selon les besoins.This very handy device will allow the operator to easily position the injection nozzle exactly over the joint or crack to be filled and precisely follow its path, just as it will allow him to immediately order the arrival of the sealant at the nozzle or interruption of the flow, as required.

En principe, la source de produit d'étanchement sous pression et à température adéquate sera portée par un appareillage automoteur annexe, de tout type co nnu, et dans ce cas, la buse d'injection dudit appareil d'application pourra lui être reliée par une conduite souple pourvue d'une chemise extérieure dans laquelle peut circuler un fluide thermorégulé de maintien en température dudit produit.In principle, the source of sealant under pressure and at an adequate temperature will be carried by an ancillary self-propelled apparatus, of any type known, and in this case, the injection nozzle of said application device may be connected to it by a flexible pipe provided with an outer jacket in which a thermoregulated fluid for maintaining the temperature of said product can circulate.

Le fluide thermorégulé en question pourra être par exemple de l'huile, dont la circulation dans la chemise est assurée par une pompe, et dont le maintien à la température voulue pourra être assuré par des brûleurs ou analogues, pompe et brûleurs étant bien entendu prévus sur l'appareillage automoteur précité.The thermoregulated fluid in question may for example be oil, the circulation of which in the jacket is ensured by a pump, and the maintenance of which at the desired temperature may be provided by burners or the like, pump and burners being of course provided on the aforementioned self-propelled equipment.

Selon un mode d'exécution préférentiel d'un appareil conforme à l'invention, le châssis pourra porter encore au moins une roue propre à rouler sur le revêtement, et on pourra prévoir que l'emplacement de la roue est intermédiaire entre celui des poignées et celui de la buse, lesquelles poignées et buse sont situées à deux extrémités opposées dudit châssis.According to a preferred embodiment of an apparatus according to the invention, the chassis may still carry at least one wheel suitable for rolling on the covering, and provision may be made for the location of the wheel to be intermediate between that of the handles and that of the nozzle, which handles and nozzle are located at two opposite ends of said chassis.

Cette disposition rend l'appareil très maniable et permet à l'opérateur de suivre très facilement le parcours du joint ou de la fissure à combler et en outre la roue pourra servir de béquille lorsque l'appareil ne sera plus utilisé.This arrangement makes the device very handy and allows the operator to easily follow the course of the joint or crack to be filled and in addition the wheel can be used as a stand when the device is no longer used.

Selon encore une disposition avantageuse, un appareil conforme à l'invention pourra être caractérisé en ce que l'extrémité du châssis qui porte la buse d'injection présente 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 ledit revêtement lorsque la buse d'injection occupe la position abaissée précitée, et forme ainsi un sabot racleur.According to another advantageous arrangement, an apparatus according to the invention can be characterized in that the end of the chassis which carries the injection nozzle has in plan substantially the shape of a triangle open towards the front - in view of the normal direction of advance provided for the device - and in the rear angle from which said nozzle is located, this triangle part being provided so that its lower edge bears on said coating when the injection nozzle occupies the lowered position mentioned above, and thus forms a scraper shoe.

Cette disposition, en forme de triangle ouvert vers l'avant, du sabot racleur, 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.This arrangement, in the shape of a triangle open towards the front, of the scraper shoe, will allow the user an easy observation of the superposition of the injection nozzle and of the seal 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 prevent 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 assurée 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 may 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 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 ouanalogues, 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 analogs, 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 apparatus could also consist in the fact that said chassis also 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 a 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 roue 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 apparatus has been globally referenced at 1. This chassis may consist of welded flat bars, referenced at 2, braced at 3, to which is fixed, by means of a clevis 4 and welded rods 5, a rolling wheel 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, represented 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 root shoe 8 is fixed an injection nozzle 9, the outlet of which opens in the immediate vicinity of the surface of the covering 10 when the device occupies the position shown in the figure, for which said scraper shoe 8 bears 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 à l'amiante.The oil return line has been designated at 13. The lines 12 and 13 are suitably insulated, for example with 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 assurée 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 handle 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 poignée 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 handle 23, carried by the other handle 7 and connected, by a Bowden-type cable 24 , to a lever 25 of the valve, the closing of the valve being ensured by another res recall spell, referenced in 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 en 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, located for example in 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 assurer 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 maque de produit.The operator, grasping the device 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 the joint or crack to be filled 27, and ensure 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 obtiendra toujours un joint 28 exactement de niveau avec le revêtement 10.The shoe 8 scraping the coating, we will always get 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 exepcée 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, with a slight downward pressure on the handles 7, to pivot the appliance to take off the scraper shoe 8 '' and make him occupy a raised position for which he is not no longer in contact with the coating 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 spécialement envisagés ; elle en embrasse, au contraire, toutes les variantes.As is obvious, and as 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 especially 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 sealing product injection nozzle 9, and on the contrary the nozzle for spraying 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 be pressed 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.
