Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne une station de lavage de bennes de chantier prévues pour recevoir du béton.The present invention relates to a car wash station site designed to receive concrete.

ARRIÈRE-PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

Il est connu de la demande de brevet US-2006/277783 une structure support d'objets en forme de trémie contenant provisoirement des produits liquides ou solides qui seront par la suite évacués de la trémie lors de l'ouverture d'une trappe disposée dans le fond de celle-ci.It is known from the patent application US 2006/277783 a hopper-shaped object support structure temporarily containing liquid or solid products which will subsequently be evacuated from the hopper when opening a trap located in the bottom thereof.

Cette structure support est constituée de quatre piliers réunis deux à deux à proximité de leurs bases par des traverses horizontales, le sommet de chacun de tels piliers comportant un moyen apte à coopérer avec un moyen complémentaire disposé le long d'une arête verticale de la trémie à supporter.This support structure consists of four pillars united two by two near their bases by horizontal crosspieces, the top of each of these pillars having means adapted to cooperate with a complementary means disposed along a vertical edge of the hopper to support.

Si cette structure support est apte à recevoir un objet pesant quelques kilos, voire quelques dizaines de kilos, il est évident qu'elle est en revanche impropre à supporter un objet pesant plusieurs quintaux, voire plusieurs tonnes, et ce pour deux raisons :

  • sous une telle charge, les piliers de ladite structure s'écarteront et l'objet chutera sur le sol, voire basculera et se videra de son contenu si dans le même temps un ou plusieurs des piliers de la structure se couche(nt),
  • le nettoyage régulier de l'objet supporté est quasiment impossible à réaliser car, puisque l'objet est lourd, mais aussi creux de par sa fonction de contenant, sa hauteur sera à l'évidence importante et le lavage de son intérieur ne sera rendu possible pour des opérateurs que si ces derniers utilisent un dispositif élévateur placé à côté de l'objet à laver les amenant au-dessus de l'ouverture supérieure ayant servi à son remplissage en produits liquides ou solides.
If this support structure is able to receive an object weighing a few kilos, even a few tens of kilos, it is obvious that it is however unsuitable to support an object weighing several quintals, even several tons, and this for two reasons:
  • under such a load, the pillars of said structure will deviate and the object will fall on the ground, or even rock and empty of its contents if at the same time one or more of the pillars of the structure is lying (nt),
  • the regular cleaning of the supported object is almost impossible to achieve because, since the object is heavy, but also hollow because of its container function, its height will be obviously important and the washing of its interior will be made possible operators only if they use a lifting device placed next to the object to be wash them over the upper opening used for filling liquid or solid products.

Une telle structure support ne peut donc pas convenir au lavage de bennes à béton dont le poids est fréquemment de plusieurs tonnes et dont la hauteur atteint souvent deux mètres, si ce n'est davantage.Such a support structure can not be suitable for washing concrete skips whose weight is frequently several tons and whose height often reaches two meters, if not more.

Certains chantiers mettant en oeuvre du béton, notamment en vue de la construction d'immeubles ou d'ouvrages d'art, utilisent en effet des bennes comprenant une large ouverture supérieure, recevant le béton, et des formes inférieures présentant des surfaces intérieures inclinées permettant au béton de glisser en se dirigeant vers une trappe centrale qui délivre le béton en un point précis.Some sites using concrete, especially for the construction of buildings or engineering structures, in fact use bins comprising a large upper opening, receiving the concrete, and lower forms having inclined interior surfaces allowing concrete to slide towards a central hatch that delivers the concrete at a specific point.

Les bennes à béton comportent en outre, généralement en partie supérieure, des moyens d'accrochage permettant de les suspendre à une grue, pour successivement les présenter au dispositif délivrant le béton, qui peut être un camion toupie ou une centrale à béton installée sur le chantier, et les présenter au-dessus du coffrage recevant ce béton.The concrete dumps further comprise, generally in the upper part, hooking means for suspending them to a crane, to successively present them to the device delivering the concrete, which can be a truck or a concrete mixer plant installed on the site, and present them above the formwork receiving this concrete.

Par ailleurs, afin de nettoyer des contenants recevant du béton, comme les bennes à béton, un type d'installation de lavage connu, présenté notamment par le document FR-A1-2942417 , comporte une plate-forme supérieure recevant les contenants, permettant à un opérateur de les rincer avec un jet d'eau. Cette installation de lavage comporte de plus en dessous d'elle des bacs de traitement et de recyclage des eaux de lavage.Moreover, in order to clean containers receiving concrete, such as concrete bins, a type of known washing installation, presented in particular by the document FR-A1-2942417 , has an upper platform receiving the containers, allowing an operator to rinse with a jet of water. This washing installation further includes beneath it treatment tanks and recycling washing water.

Il est connu aussi de réaliser des tours de lavage des bennes à béton, comprenant une structure métallique porteuse qui présente en partie supérieure des moyens de support de la benne.It is also known to carry out washing towers concrete bins, comprising a metal carrying structure which has in the upper part support means of the bucket.

En particulier, un type de benne à béton connu adapté pour ces tours de lavage comporte dans la partie supérieure de son corps deux barres horizontales latérales disposées suivant un même axe passant sensiblement par le milieu de la benne, barres horizontales qui sont soudées à l'extérieur du corps de la benne afin de dépasser de chaque côté et de former ainsi des tenons qui s'ajustent dans des berceaux disposés en haut de la tour de lavage. De telles barres horizontales sont rajoutées sur les bennes standard.In particular, a type of known concrete container adapted for these washing towers comprises in the upper part of its body two lateral horizontal bars arranged along the same axis passing substantially through the middle of the bucket, horizontal bars which are welded to the outside the body of the bucket to overtake on each side and thus form tenons that fit into cradles at the top of the wash tower. Such horizontal bars are added to the standard skips.

Les berceaux de la tour de lavage présentent une forme large ouverte vers le haut qui se resserre en descendant afin de réaliser un centrage des deux barres et un positionnement précis de la benne à béton.The cradles of the washing tower have a broad open shape upwards which narrows downward to achieve a centering of the two bars and a precise positioning of the concrete bucket.

Il semble évident que ce moyen de positionnement des bennes sur la tour de lavage pose notamment des problèmes d'encombrement plus important, et de sécurité. Les deux barres dépassant à l'extérieur de ces bennes forment en effet des excroissances qui peuvent être dangereuses pour le personnel circulant autour des bennes. De plus, ce moyen de positionnement des bennes sur la tour de lavage n'étant pas standard sur les bennes du commerce, il se pose le problème de la modification des bennes existantes pour une utilisation sur les tours de lavage.It seems obvious that this means of positioning the buckets on the washing tower poses particular problems of greater size and security. The two bars protruding outside of these buckets form indeed excrescences which can be dangerous for the personnel circulating around the buckets. In addition, this means of positioning the skips on the washing tower is not standard on commercial skips, there is the problem of modifying the existing skips for use on washing towers.

DESCRIPTION GÉNÉRALE DE L'INVENTIONGENERAL DESCRIPTION OF THE INVENTION

La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure.The present invention is intended to avoid these disadvantages of the prior art.

Elle propose à cet effet une tour de lavage prévue pour recevoir une benne à béton, afin de la laver, le corps de cette benne présentant des faces inférieures inclinées vers le bas vers le centre et qui se terminent en-dessous par une ouverture de sortie du béton fermée par une trappe commandée par un levier, ladite tour de lavage comprenant une structure porteuse formée par des tubes métalliques et présentant en partie supérieure des moyens de support de la benne, ladite tour étant au surplus caractérisée en ce qu'elle comprend deux étages et en ce que le plancher du deuxième étage présente une ouverture encadrée par des tubes de support latéraux horizontaux qui reçoivent des patins de guidage prévus pour entourer la benne en constituant l'appui de deux des faces inclinées et en assurant un support et un calage de cette benne.It proposes for this purpose a washing tower provided for receiving a concrete bucket, to wash it, the body of this bucket having lower faces inclined downwards towards the center and which end below by an outlet opening concrete closed by a flap controlled by a lever, said washing tower comprising a bearing structure formed by metal tubes and having in the upper part support means of the bucket, said tower being further characterized in that it comprises two stages and in that the floor of the second floor has an opening framed by horizontal lateral support tubes which receive guide pads provided to surround the bucket constituting the support of two inclined faces and providing support and rigging of this bucket.

Un avantage de cette tour de lavage est que les patins constituent des moyens simples et efficaces de centrage de la benne qui descend sur la tour, les faces inférieures inclinées de cette benne glissant sur les patins pour effectuer son centrage, ce qui permet d'obtenir en fin de descente une position précise de la benne se trouvant en appui stable sur les patins l'entourant.An advantage of this washing tower is that the pads are simple and effective means of centering the bucket that goes down on the tower, the lower inclined faces of this skip sliding on the skids to perform its centering, which allows to obtain at the end of the descent a precise position of the bucket being in stable support on the skids surrounding it.

La benne utilisant alors seulement ses faces inférieures inclinées pour son centrage et son appui, et n'étant pas équipée de barres tournées vers l'extérieur pour réaliser ces fonctions, on comprend qu'elle impose un encombrement réduit et qu'elle présente moins de danger pour le personnel circulant autour.The bucket then using only its lower faces inclined for its centering and support, and not being equipped with bars turned outwardly to perform these functions, it is understood that it imposes a small footprint and has less danger for the personnel circulating around.

Un autre avantage de cette tour de lavage est que l'ensemble des bennes standard existantes est utilisable sans modification, le positionnement de ces bennes étant réalisé sur les surfaces extérieures existantes de celles-ci.Another advantage of this washing tower is that all existing standard buckets can be used without modification, the positioning of these buckets being made on the existing external surfaces thereof.

La tour de lavage de bennes à béton selon l'invention peut de plus comporter une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles.The concrete bin washing tower according to the invention may further comprise one or more of the following features, which may be combined with each other.

Ainsi, avantageusement, la tour de lavage peut comporter sur chaque support latéral horizontal deux patins espacés.Thus, advantageously, the washing tower may comprise on each horizontal lateral support two spaced pads.

De préférence, chaque patin comporte un élément roulant prévu pour rouler sur une face inférieure inclinée de la benne.Preferably, each pad comprises a rolling element provided for rolling on an inclined lower face of the bucket.

En particulier, chaque patin peut comporter un rouleau monté sur un axe horizontal, maintenu parallèlement au tube de support latéral par deux pattes fixées sur ce tube.In particular, each pad may comprise a roller mounted on a horizontal axis, held parallel to the lateral support tube by two lugs fixed on this tube.

Selon un autre mode préféré de réalisation, la tour de lavage comporte également une goulotte disposée en dessous de l'ouverture centrale du plancher du deuxième étage, ladite goulotte permettant de recevoir les eaux de lavage venant de la trappe inférieure de la benne en cours de lavage et pour les diriger vers le bas sans risquer d'asperger l'extérieur de la tour de lavage.According to another preferred embodiment, the washing tower also comprises a trough disposed below the central opening of the floor of the second floor, said trough making it possible to receive the washing water coming from the lower hatch of the bucket during the washing and to direct them down without risking spraying the outside of the scrubber.

Avantageusement, la tour de lavage comporte au moins une arrivée d'eau propre destinée au lavage de la benne à béton.Advantageously, the washing tower comprises at least one inlet of clean water for washing the concrete body.

En particulier, elle peut être dotée de deux distributions d'eau propre disposées respectivement au premier étage et au deuxième étage de cette tour.In particular, it can be provided with two distributions of clean water respectively located on the first floor and the second floor of this tower.

De préférence, la tour de lavage comporte des bacs de traitement et de recyclage de ses eaux de lavage.Preferably, the washing tower comprises bins for treating and recycling its washing water.

De préférence également, la tour de lavage comprend une nacelle disposée au deuxième étage, en arrière de l'ouverture.Also preferably, the washing tower comprises a nacelle disposed at the second floor, behind the opening.

Avantageusement, la structure porteuse de la tour de lavage est formée par un ensemble monobloc soudé prévu pour être fabriqué en atelier, et transporté d'une seule pièce sur le chantier.Advantageously, the carrying structure of the washing tower is formed by a welded monoblock assembly intended to be manufactured in the workshop, and transported in one piece on the site.

DESCRIPTION DES MODES DE RÉALISATION PRÉFÉRÉS DE L'INVENTIONDESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

La figure 1 présente un exemple d'une benne à béton 2 constituée par l'assemblage de tôles et de barres soudées qui forment ainsi un réceptacle comprenant un corps dont la partie supérieure présente quatre faces planes verticales 4 formant en vue de dessus un carré ou un rectangle, chacune de ces faces se prolongeant vers le bas selon une face (6) qui est inclinée en direction du centre.The figure 1 shows an example of a concrete container 2 constituted by the assembly of sheets and welded bars which thus form a receptacle comprising a body whose upper part has four vertical planar faces 4 forming a top view of a square or a rectangle, each of these faces extending downwardly along a face (6) which is inclined towards the center.

Les faces inclinées 6 se terminent en partie basse par une ouverture inférieure fermée par une trappe commandée par un levier 8. Une goulotte inférieure 10, disposée en dessous de cette trappe, recentre la descente du béton vers une sortie centrale circulaire.The inclined faces 6 terminate in the lower part by a lower opening closed by a flap controlled by a lever 8. A lower chute 10, disposed below this trap, refocuses the descent of the concrete to a circular central outlet.

Un châssis tubulaire 12 comporte deux tubes prenant appui sur un côté de la benne à béton 2, appelé par convention côté avant, lesquels tubes descendent suivant une forme arrondie pour venir en dessous de la goulotte inférieure 10 afin de former un cadre qui entoure cette goulotte ainsi que le dispositif de commande de la trappe 8, et dont le rôle est de les protéger des chocs.A tubular frame 12 comprises two tubes bearing on one side of the concrete container 2, conventionally called front side, which tubes descend in a rounded shape to come below the lower chute 10 to form a frame that surrounds this chute and the control device of the hatch 8, and whose role is to protect them from shocks.

Deux côtés de la benne à béton 2, appelés par convention côtés latéraux, se prolongent au-dessus par une tôle triangulaire 14 comprenant une pointe centrale tournée vers le haut, chaque pointe recevant un anneau de levage 16 de la benne 2. Ces deux pointes centrales sont reliées entre elles par une traverse 18 qui assure une rigidification en empêchant un rapprochement des anneaux 16 lors d'un levage par une grue de la benne chargée.Two sides of the concrete bucket 2, conventionally called side sides, extend above by a triangular plate 14 comprising a central tip facing upwards, each point receiving a lifting ring 16 of the bucket 2. These two tips Central units are interconnected by a cross member 18 which provides a stiffening preventing the approaching rings 16 when lifting by a crane of the loaded bucket.

Une barre horizontale 22 de section carrée dépassant vers l'extérieur est fixée en haut de chaque côté latéral du corps de la benne, et les deux barres 22 ainsi rapportées sont alignées sur un même axe passant sensiblement par le centre de la benne 2. Au-dessus de chaque barre 22, deux goussets triangulaires de renforcement 20 prennent appui sur la tôle triangulaire 14 afin de permettre un portage de la benne par ces barres.A horizontal bar 22 of square section projecting outwards is fixed at the top of each lateral side of the body of the body, and the two bars 22 thus reported are aligned on the same axis passing substantially through the center of the body 2. Au above each bar 22, two triangular reinforcing gussets 20 are supported on the sheet metal triangular 14 to allow a port of the bucket by these bars.

Les deux barres extérieures latérales 22 constituent des formes fortement saillantes comprenant des arêtes vives qui, lorsque les bennes sont posées au sol, debout ou couchées, se trouvent à hauteur du personnel circulant sur le chantier. Il existe alors, du fait même de l'existence de ces barres extérieures 22, des risques d'accidents provoqués par les bennes posées au sol ou en cours de manutention par des grues, notamment lors d'une approche d'un poste de travail présentant des opérateurs disposés autour.The two outer lateral bars 22 form highly protruding forms including sharp edges which, when the dumpsters are placed on the ground, upright or lying down, are found at the height of the staff circulating on site. There is then, by the very fact of the existence of these outer bars 22, the risk of accidents caused by skips placed on the ground or being handled by cranes, especially when approaching a workstation presenting operators arranged around.

Un autre inconvénient de telles bennes est que leur encombrement extérieur est plus important et qu'elles nécessitent donc un espace de stockage plus grand.

  • La figure 2 présente, toujours à titre d'exemple, une benne 2 traditionnelle, similaire à la précédente si ce n'est qu'elle ne comporte toutefois pas de barres extérieures 22. Les côtés latéraux de cette autre benne sont sensiblement lisses, en ce sens qu'ils ne présentent pas de partie saillante vers l'extérieur.
  • La figure 3 présente une tour de lavage comprenant une structure porteuse formée par des tubes métalliques de section carrée soudés entre eux, ce qui facilite leurs assemblages.
  • La tour de lavage présente un rez-de-chaussée 32 comportant sur un côté latéral une première échelle 34 donnant accès à un premier étage 38 qui comprend un plancher muni d'une trappe d'accès 36 disposée en haut de cette échelle. Le premier étage 38 comporte, sur le côté latéral opposé, une deuxième échelle 40 donnant accès à une nacelle 44 qui occupe toute la partie arrière d'un deuxième étage 42.
Another disadvantage of such skips is that their external dimensions are larger and they therefore require a larger storage space.
  • The figure 2 presents, by way of example, a traditional skip 2, similar to the previous one except that it does not however comprise outer bars 22. The lateral sides of this other skip are substantially smooth, in that they do not have any protruding part towards the outside.
  • The figure 3 has a washing tower comprising a supporting structure formed by metal tubes of square section welded together, which facilitates their assemblies.
  • The washing tower has a ground floor 32 having on one lateral side a first scale 34 giving access to a first stage 38 which comprises a floor provided with an access door 36 disposed at the top of this ladder. The first stage 38 comprises, on the opposite lateral side, a second scale 40 giving access to a nacelle 44 which occupies the entire rear part of a second stage 42.

Le plancher de la partie avant du deuxième étage 42 présente une vaste ouverture centrale rectangulaire 58 encadrée par deux tubes de support latéraux horizontaux 46 qui reçoivent chacun deux patins de guidage espacés 48.The floor of the front portion of the second floor 42 has a large rectangular central opening 58 flanked by two horizontal lateral support tubes 46 which each receive two spaced apart guide pads 48.

Chaque patin de guidage 48 détaillé figure 4 comporte un rouleau 60 monté sur un axe horizontal 62 maintenu parallèlement au tube de support latéral 46 par deux fers plats 64 formant des pattes soudées perpendiculairement à ce tube. On obtient ainsi de manière simple et économique des patins comprenant des rouleaux 60 qui peuvent tourner sur leur axe tout en supportant des charges importantes.Each guide pad 48 detailed figure 4 comprises a roller 60 mounted on a horizontal axis 62 maintained parallel to the lateral support tube 46 by two flat irons 64 forming tabs welded perpendicularly to this tube. In this way, skates are easily and economically obtained comprising rollers 60 which can rotate on their axis while supporting large loads.

Une goulotte 50 de récupération des eaux de lavage, disposée en dessous de l'ouverture centrale 58 du plancher du deuxième étage 42, se prolonge vers le haut, selon une partie frontale 52 et deux flancs de protection de faible largeur, et elle se termine en bas par un volet d'orientation des eaux usées.A washing water collection trough 50, disposed below the central opening 58 of the floor of the second floor 42, extends upwards, along a front portion 52 and two protective flanks of small width, and ends at the bottom by a flap of orientation of the waste water.

Le premier étage 38 et le deuxième étage 42 comportent chacun une arrivée 56 d'eau propre, ainsi qu'un support d'enroulage d'un tuyau d'arrosage recevant cette eau propre.The first stage 38 and the second stage 42 each comprise an inlet 56 of clean water, as well as a winding support for a garden hose receiving this clean water.

En particulier, l'eau propre peut venir d'une arrivée d'eau extérieure. L'eau propre peut venir aussi de bacs de traitement de l'eau de lavage produite par cette même tour, comme indiqué dans le document cité dans l'art antérieur présenté ci-dessus. La tour de lavage forme alors une installation complète de nettoyage comprenant un recyclage interne de son eau, tour de lavage qui consomme alors peu d'eau extérieure et qui est donc plus écologique.In particular, clean water can come from an outside water supply. The clean water can also come from tanks for treating the washing water produced by this same tower, as indicated in the document cited in the prior art presented above. The washing tower then forms a complete cleaning installation including an internal recycling of its water, washing tower which then consumes little external water and which is therefore more ecological.

Avantageusement, la tour de lavage est constituée d'une structure monobloc compacte soudée en atelier, recevant ses équipements pour être prête à l'emploi, et qui est ensuite déposée sur un camion pour être transportée sur les chantiers. On évite ainsi des manipulations de montage sur le chantier, lesquelles sont toujours la source d'erreurs ainsi que des risques d'incidents.Advantageously, the washing tower consists of a compact monobloc structure welded in the workshop, receiving its equipment to be ready for use, and which is then deposited on a truck to be transported to the sites. In this way, site-mounted installation operations are avoided, which are always the source of errors as well as the risk of incidents.

On note que, la benne à béton 2 ne comportant pas de barre extérieure latérale 22 dépassant sur les côtés 4, la largeur de la tour de lavage suivant l'invention peut être réduite par rapport à un type de tour connu conçu pour recevoir de telles bennes équipées des barres extérieures.It should be noted that, since the concrete container 2 does not have a lateral outer bar 22 projecting from the sides 4, the width of the washing tower according to the invention can be reduced compared to a known type of tower designed to receive such skips equipped with external bars.

Les figures 5 et 6 présentent en vue de côté, et respectivement en vue en perspective, la tour de lavage conforme à l'invention où deux opérateurs traitent la benne à béton 2. Lors de sa mise en place par la grue, ladite benne 2 a été disposée de telle sorte que ses faces latérales inférieures inclinées 6 viennent en appui sur les rouleaux 60 des patins 48 au fur et à mesure de la descente, ce qui évite des frottements. On obtient ainsi, par ce roulement des rouleaux 60, un guidage latéral permanent de la benne à béton 2.The figures 5 and 6 present in side view, and respectively in perspective view, the washing tower according to the invention where two operators process the concrete bucket 2. When it is put in place by the crane, said bucket 2 has been arranged in such a way that its inclined lower lateral faces 6 bear on the rollers 60 of the skids 48 as the descent, which avoids friction. By this rolling of the rollers 60, a permanent lateral guidance of the concrete container 2 is thus obtained.

Lorsqu'elle est complétement posée, stabilisée et enchâssée entre les patins 48, la benne à béton 2 est calée en position sur son support et elle ne peut donc plus bouger. Les opérateurs 70 peuvent ainsi travailler sur les deux étages 38, 42 de la tour de lavage en toute sécurité, pour laver avec le jet d'eau aussi bien la partie inférieure, comprenant la trappe de sortie et la goulotte inférieure 10 de la benne, que la partie supérieure et l'intérieur de son corps 2.When it is completely laid, stabilized and embedded between the pads 48, the concrete bucket 2 is wedged in position on its support and therefore can not move. The operators 70 can thus work on the two stages 38, 42 of the washing tower safely, to wash with the jet of water as well the lower part, comprising the outlet hatch and the lower chute 10 of the bucket, that the upper part and the inside of his body 2.

Comme il va de soi, l'invention ne se limite pas aux seuls modes d'exécution préférentiels décrits ci-dessus.It goes without saying that the invention is not limited to the only preferred embodiments described above.

Elle embrasse au contraire toutes les variantes possibles de réalisation, pour autant que ces dernières ne sortent pas du cadre délimité par les revendications ci-jointes qui définissent la portée de la présente invention.On the contrary, it embraces all the possible variants of embodiment, insofar as the latter do not go beyond the scope delimited by the appended claims which define the scope of the present invention.
