Description
La présente invention concerne d'une façon générale un appareil pour l'application d'un produit liquide de ragréage des sols.The present invention relates generally to an apparatus for applying a liquid soil leveling product.
On connaît principalement deux techniques, toutes deux manuelles, pour appliquer et répartir au sol un produit de ragréage se présentant sous forme essentiellement liquide.Two techniques are known, both manual, for applying and distributing on the ground a patching product in essentially liquid form.
Selon la première technique, l'opérateur travaille à genoux. Cette méthode est très majoritairement pratiquée depuis plusieurs décennies. L'opérateur verse sur le sol une dizaine de kg de produit à partir d'un bidon dans lequel quelques dizaines de kg de produit ont été préparés, en général par mélange d'un produit pulvérulent avec de l'eau.According to the first technique, the operator works on his knees. This method is mostly used for several decades. The operator pours on the ground about ten kg of product from a can in which a few tens of kg of product have been prepared, usually by mixing a powdery product with water.
Puis l'opérateur, en position à genoux, étale le produit par un mouvement de va-et-vient à l'aide d'un platoir ou d'une lisseuse, tenu à bout de bras.Then the operator, in kneeling position, spreads the product by a movement back and forth with the aid of a buncher or a smooth, held at arm's length.
Il en résulte une très forte pénibilité générant une perte de productivité au fil des heures. En outre, les mouvements de va et vient laissent fréquemment le défaut d'un effet de vague qui subsiste après le séchage du produit.This results in a very heavy workload generating a loss of productivity over the hours. In addition, the movements back and forth often leave the defect of a wave effect that remains after the drying of the product.
Pour l'opérateur, outre la fatigue physique immédiate, la forte pénibilité se manifeste par l'apparition de douleurs musculaires et articulaires évoluant à plus ou moins long terme en troubles musculo-squelettiques (TMS) au niveau des genoux, des bras, des épaules et du dos.For the operator, in addition to the immediate physical fatigue, the severe pain is manifested by the appearance of muscular and articular pain evolving in more or less long term musculoskeletal disorders (MSD) in the knees, arms, shoulders and back.
La deuxième technique connue est mise en oeuvre alors que l'opérateur est en position debout. Cette technique, très peu utilisée par l'ensemble de la profession, ne constitue qu'une alternative d'usage limité. Elle est mise en oeuvre à l'aide d'une spatule à lame réglable ou interchangeable pourvue de picots. Le document
On connaît également, pour usage debout, un dispositif comprenant un ensemble de rouleaux assemblés dans l'axe les uns des autres, des rondelles intercalaires entre les rouleaux, de diamètre plus grand que celui des rouleaux, permettant d'espacer du sol la surface de travail des rouleaux et de ne laisser sur le sol que l'épaisseur de produit souhaitée.Also known, for standing use, a device comprising a set of rollers assembled in the axis of each other, spacer washers between the rollers, of greater diameter than that of the rollers, for spacing from the ground the surface of rollers and leave only the desired product thickness on the floor.
Ces différents appareils sont installés au bout d'un manche afin de permettre leur utilisation debout. Mais ces outils s'avèrent peu efficaces à l'usage. En effet reste nécessaire de basculer un lourd bidon pour verser le produit, et il faut ensuite racler une quantité importante de produit lors des premiers mouvements.These different devices are installed at the end of a handle to allow their standing use. But these tools are not very effective in use. Indeed remains necessary to switch a heavy can to pour the product, and then must scrape a large amount of product during the first movements.
Par ailleurs, avec un dispositif du type décrit dans
Le dispositif à rouleau présente les mêmes inconvénients, à l'exception des sursauts dus aux aspérités du sol. Cependant les mouvements d'étalement du produit sont rendus délicats par le fait que le rouleau ne peut rouler que dans une direction perpendiculaire à son axe ; il est donc difficile de contenir et guider le produit dans la direction souhaitée et celui-ci déborde de part et d'autre du rouleau, obligeant à d'incessantes reprises. Pour effectuer ces reprises, il est nécessaire de lever le rouleau à bout de bras afin de ramener l'excès de produit ce qui est très astreignant pour l'opérateur. En outre, le poids du rouleau étant conséquent, le fait de le faire retomber dans le produit en surplus risque d'éclabousser un mur ou cloison situé à proximité.The roller device has the same disadvantages, with the exception of bursts due to the unevenness of the ground. However, the spreading movements of the product are made delicate by the fact that the roll can roll only in a direction perpendicular to its axis; it is therefore difficult to contain and guide the product in the desired direction and it overflows on both sides of the roll, forcing incessant occasions. To make these occasions, it is necessary to lift the roller arm to bring back the excess product which is very demanding for the operator. In addition, the weight of the roll being consequent, the fact of falling back into the surplus product may splash a wall or partition located nearby.
Enfin une autre technique utile à mentionner est une technique debout avec une pompe mécanique, par exemple du type décrit dans le document
L'installation sur chantier peut en outre s'avérer particulièrement difficile en cas accès boueux, présence de tranchées, passages encombrés, escaliers, etc.).On-site installation can also be particularly difficult in case of muddy access, presence of trenches, congested passages, stairs, etc.).
Enfin l'utilisation de la machine impose une alimentation électrique fiable (souvent incertaine sur chantier) car l'arrêt intempestif provoque rapidement son colmatage. Il en est de même en cas de coupure d'eau, sauf à prévoir une réserve tampon dans un bidon pour différer l'arrêt du travail ou lancer une procédure de procédure de nettoyage dans l'urgence.Finally, the use of the machine requires a reliable power supply (often uncertain on site) because the inadvertent shutdown quickly causes clogging. It is the same in case of water cut, except to provide a buffer in a can to postpone the work stoppage or initiate a cleaning procedure procedure in a hurry.
Il est aussi à noter que la réalisation du travail doit être opérée par au moins trois opérateurs, un premier alimentant la machine en poudre, un deuxième tenant la buse verseuse de produit au dessus du sol, et un troisième déplaçant au fur et à mesure de la progression le lourd tuyau rempli de produit.It should also be noted that the work must be carried out by at least three operators, a first feeding the machine powder, a second holding the product pouring nozzle above the ground, and a third moving as the progress the heavy hose filled with product.
Enfin l'avantage présumé d'un rendement élevé n'est pas systématiquement constaté, car une surface importante doit généralement être partagée avec les autres corps d'état opérant sur le chantier. Ainsi par exemple une surface de 1000 m2 est souvent traitée en 2 à 4 secteurs ragréés l'un après l'autre, ruinant alors l'intérêt de l'utilisation de la machine.Finally, the presumed advantage of a high efficiency is not systematically observed, since a large surface area must generally be shared with the other state bodies operating on the site. Thus, for example, an area of 1000 m2 is often treated in 2 to 4 sectors patched one after the other, thus ruining the interest of the use of the machine.
C'est pourquoi cette machine n'est que rarement utilisée, et tend d'ailleurs à disparaître des catalogues des fabricants et revendeurs d'outillage.That is why this machine is rarely used, and tends to disappear from the catalogs of manufacturers and resellers of tools.
L'invention a pour objet de proposer un appareil de mise en place de produit de ragréage qui permette à un opérateur de travailler debout sans fatigue, qui soit économique, simple, léger, peu encombrant, autonome (ne nécessitant pas d'alimentation en énergie à l'exception de l'alimentation d'un éventuel dispositif de mélange), facilement nettoyable et fiable, tout en assurant une qualité d'application du produit au moins équivalente à celle obtenue par un opérateur manuel expérimenté travaillant à genoux.The object of the invention is to propose an apparatus for placing a patching product which enables an operator to work standing without fatigue, which is economical, simple, light, compact, autonomous (not requiring a power supply). with the exception of feeding a possible mixing device), easily cleaned and reliable, while ensuring a product application quality at least equivalent to that obtained by an experienced manual operator working on his knees.

En référence aux Figures, on a représenté un appareil applicateur de produit liquide de ragréage qui comprend un contenant 100 pour le produit. Le contenant est en forme générale de fût et réalisé avantageusement en matière plastique, par exemple en polyéthylène haute densité. Le fût présente de préférence un diamètre de 35 à 55 cm de diamètre et une hauteur de 60 à 80 cm.Referring to the Figures, there is shown a liquid product applicator patching apparatus which comprises a
La paroi de fond 110 du contenant est percée d'un orifice 112, par exemple d'un diamètre de 40 à 60 mm, pour la communication de l'intérieur du contenant avec un dispositif 300 de distribution de produit de ragréage par l'intermédiaire d'un coude 200 à 90°.The
Ce coude réalisé par exemple par injection de PVC comprend une partie verticale 210 prolongeant l'orifice 112 vers le bas et dotée à son extrémité supérieure d'une collerette 212 s'étendant dans l'espace intérieur 120 du fût et par laquelle le coude est fixé au fût (par exemple par collage, ou à l'aide d'un écrou de serrage se vissant par le dessous, etc.) et par laquelle il est fixé dans ladite ouverture, une partie de coude 220 et une partie horizontale 230.This elbow made for example by PVC injection comprises a
A l'intérieur de la collerette 212 est prévu un joint plat annulaire souple 250, par exemple en élastomère, destiné à coopérer avec une vanne de fermeture que l'on décrira dans la suite. Il est fixé ici par encastrement périphérique dans la matière de la collerette.Inside the
L'appareil comprend en outre un manchon cylindrique intermédiaire 400 installé entre le coude 200 et le dispositif de distribution 300, manchon qui a pour fonction d'autoriser un démontage instantané du dispositif de distribution 300 par exemple en vue de son nettoyage, en cours de travail. Le manchon 400 est fixé par exemple par emboîtement ajusté à la partie horizontale 230 du coude 200.The apparatus further comprises an intermediate
Le dispositif de distribution 300 est constitué par un tube par exemple en PVC, d'un diamètre de l'ordre de 30 à 60 mm et d'une longueur de l'ordre de 300 à 600 mm. Une extrémité 310 de ce tube, ouverte, est insérée dans l'extrémité ouverte 410 du manchon 400. Par exemple, le diamètre intérieur du manchon 400 est de 42 mm, tandis que le diamètre extérieur du tube de distribution 300 est de 40 mm, un joint à lèvre 420 étant solidaire du manchon 400 dans la région de son extrémité ouverte 410 pour coopérer avec le tube 300 et assurer l'étanchéité entre ces deux pièces en cours de travail.The
La démontabilité des éléments 200, 300, 400 les uns par rapport aux autres est assurée, pour ainsi faciliter le nettoyage soit en fin d'opération, soit en cours d'opération en cas de colmatage, entrée d'un élément extérieur, etc. auquel cas la vanne d'obturation telle qu'on la décrira plus loin est mise en oeuvre.The disassembly of the
A l'extrémité opposée 320, le tube de distribution 300 est fermé par un bouchon 350 par exemple en matériau élastomère, de préférence amovible.At the
Entre ses deux extrémités, le tube est percé d'une série de lumières 320 orientées vers le bas et destinées au passage du produit de ragréage en vue de son épandage comme on va le voir dans la suite. Les lumières ont un diamètre d'environ 6 à 10 mm (déterminé notamment en fonction de la viscosité plus ou moins importante du produit de ragréage liquide), préférentiellement d'environ 8 mm, et sont espacées mutuellement d'une distance de 20 à 50 mm, par exemple de 40 mm. Selon la longueur du tube 100 et des valeurs choisies pour le diamètre des lumières et leur espacement, on prévoit typiquement entre 4 et 15 lumières.Between its two ends, the tube is pierced by a series of
L'appareil selon l'invention comprend en outre une vanne 500 permettant de sélectivement autoriser et empêcher l'écoulement du produit de ragréage du contenant 100 vers le dispositif distributeur 300. Cette vanne comprend un organe d'obturation 510 apte à pénétrer à partir du haut dans la collerette 212 du coude 200. Cet organe d'obturation 510 est surmonté d'un manche 520 s'étendant verticalement dans l'espace intérieur 120 du fût 100, réalisé par exemple à partir d'un tube de PVC assemblé à la partie d'obturation 510, également en PVC. L'extrémité supérieure du manche, située sensiblement au sommet du fût 100 ou débordant vers le haut par rapport à celui-ci, forme une poignée de manoeuvre 530.The apparatus according to the invention further comprises a
Comme le montre la
Les diamètres des différentes parties sont choisis en fonction du rôle qu'elles ont à jouer, en étant de l'ordre de 30 à 50 mm pour les parties de plus petit diamètre et de 40 à 80 mm pour la partie de plus grand diamètre.The diameters of the different parts are chosen according to the role they have to play, being of the order of 30 to 50 mm for the smaller diameter parts and 40 to 80 mm for the larger diameter part.
A noter que l'obturation est assurée à la fois par l'appui entre les épaulements des collerettes 518, 212 et par la coopération entre le joint plat 250 et la périphérie de la partie 514.Note that the closure is provided both by the support between the shoulders of the
L'ensemble formé par le contenant 100, l'équipement de distribution 200, 300, 400 et la vanne 500 est monté sur un chariot 600. Ce chariot comprend une plateforme 610 par exemple de forme circulaire ou carrée, sur laquelle repose la base 110 du fût 100. La plateforme est constituée par exemple d'une planche dont les dimensions sont adaptées à celles de la base du fût (par exemple un carré de 300 à 500 mm de côté).The assembly formed by the
La plateforme 610 est montée sur trois ou quatre roulettes 620 (ici quatre roulettes agencées aux quatre coins d'un carré), qui sont toutes librement pivotantes autour d'un axe vertical, en étant éventuellement verrouillables.The
Une découpe de dimensions appropriées est formée dans la plateforme 610 pour loger le manchon 400 et l'essentiel du coude 200.A cutout of appropriate dimensions is formed in the
Comme le montre la
Avantageusement, l'appareil comprend également un dispositif de gâchage 700 qui comprend un accessoire de gâchage 710 de type batteur possédant un manche 712 descendant dans le liquide contenu dans le fût (à distance appropriée de la vanne pour éviter de perturber son fonctionnement) et pourvu à son extrémité libre de la partie 714 formant batteur proprement-dit. L'accessoire est monté ici sur un appareil électroportatif tel qu'une perceuse 720. En variante, il pourrait s'agir d'un moteur dédié, alimenté sur secteur ou par batterie rechargeable.Advantageously, the apparatus also comprises a
Le dispositif de gâchage est monté de façon amovible sur un support 120 solidaire du fût 100. Avantageusement, ce support 120 occupe seulement une partie de l'ouverture supérieure du fût de manière à pouvoir vérifier visuellement le niveau de produit liquide de ragréage dans le fût. Il sert également de préférence à guider et retenir la partie supérieure 530 de la vanne 500, et à permettre, à l'aide d'une goupille, d'une mâchoire ou de tout autre élément mécanique approprié, à retenir la vanne en position haute (ouverte) ou basse (fermée).The mixing device is removably mounted on a
Optionnellement, on prévoit dans la région supérieure du fût 100, par exemple fixée au support 120, une poignée (non représentée) permettant de faciliter le guidage de l'appareil lors de ses déplacements. Par exemple, il peut s'agir de deux poignées verticales ou inclinées permettant de tenir l'appareil à deux mains en formant un guidon.Optionally, there is provided in the upper region of the
L'appareil selon l'invention s'utilise de la façon suivante :
- après avoir vérifié que la vanne 500 était fermée, l'opérateur verse une dose de poudre et la quantité d'eau correspondante dans le fût 100 ; le dispositif de gâchage étant en service, le mélange s'effectue de façon autonome ;
- l'alimentation électrique du dispositif de gâchage étant débranchée, l'appareil est déplacé en le faisant rouler jusqu'au site d'application du produit, puis l'opérateur ouvre la vanne 500 en levant le manche 520 à l'aide de la poignée de
manoeuvre 530, - le produit commence alors à s'écouler par gravité entre l'intérieur de la cuve 100 et le distributeur 300 et à sortir de façon répartie au niveau des différentes lumières 320, et l'opérateur déplace alors l'appareil, le plus souvent à la fois en rotation et en translation, de manière à adapter la quantité de produit épandue à l'épaisseur recherchée, elle-même fonction en général de l'état du sol ;
- une fois l'application terminée, la vanne 500 est refermée et l'appareil peut être déplacé vers une autre zone à traiter ; si le traitement est terminé, le dispositif distributeur 300 est démonté pour être nettoyé, de même que le fond de la cuve 100 et la vanne 500.
- after verifying that the
valve 500 was closed, the operator pours a dose of powder and the corresponding amount of water into thedrum 100; the mixing device is in use, the mixture is carried out autonomously; - the power supply of the mixing device being disconnected, the apparatus is moved by rolling it to the application site of the product, then the operator opens the
valve 500 by lifting thehandle 520 with thehandle maneuvering machine 530, - the product then begins to flow by gravity between the inside of the
tank 100 and thedistributor 300 and to leave distributedly at thevarious lights 320, and the operator then moves the device, usually to the both in rotation and in translation, so as to adapt the amount of product spread to the desired thickness, itself in general function of the state of the soil; - once the application is completed, the
valve 500 is closed and the device can be moved to another area to be treated; if the treatment is finished, thedispensing device 300 is disassembled for cleaning, as well as the bottom of thetank 100 and thevalve 500.
Selon la variante illustrée sur les
L'élément 800 est de préférence fixé au dispositif de distribution 300, par exemple à l'aide de colliers, pattes ou crochets de fixation 820. Alternativement, les éléments 300 et 800 peuvent être formés d'un seul tenant, par exemple par injection de matière plastique.The
Des essais ont été effectués avec un appareil selon l'invention. L'appareil a permis à une personne peu expérimentée de traiter plusieurs milliers de mètres carrés de locaux cloisonnés avec une haute qualité d'application, sans effort et sans fatigue. On note qu'il peut être aisément manipulé et utilisé par un opérateur seul.Tests were carried out with an apparatus according to the invention. The device allowed an inexperienced person to treat several thousand square meters of partitioned premises with a high quality of application, effortlessly and without fatigue. It is noted that it can be easily handled and used by a single operator.
Bien entendu, la présente invention n'est nullement limitée à la forme de réalisation décrite et représentée, mais l'homme du métier saura y apporter de nombreuses variantes et modifications.Of course, the present invention is not limited to the embodiment described and shown, but the skilled person will be able to make many variations and modifications.
