Description

MACHINES POUR L'EXECUTION DE CHAPES EN BETON ET PRODUITS ANALOGUES MACHINES FOR THE EXECUTION OF CONCRETE SCREEDS AND THE LIKE
la présente Invention concerne une nouvelle machine permettant la réalisation, très rapide, de chapes parfaitement planes quelles que soient leur lon¬ gueur et leur largeur. Lorsqu'il y a lieu de réaliser une chape par¬ faitement plane, par exemple, celle constituant le sol d'un court de tennis, d'une piste ou d'un autre ensem¬ ble, il est nécessaire de former progressivement la chape et de la ragréer pour qu'aucun joint ne soit ap- parent, le ragréage et le lissage d'une chape consti¬ tuant des opérations longues et délicates qui augmen¬ tent très sensiblement le prix de revient d'une chape, quels que soient les matériaux utilisés, qu'il s'agisse d'un simple béton ou de produits plus élaborés à base de résines diverses.the present invention relates to a new machine allowing the realization, very quickly, of perfectly flat screeds whatever their length and width. When it is necessary to make a perfectly flat screed, for example, that constituting the ground of a tennis court, a track or another set, it is necessary to gradually form the screed and to level it off so that no joint is apparent, the leveling and smoothing of a screed constituting long and delicate operations which very significantly increase the cost price of a screed, whatever the materials used, whether simple concrete or more elaborate products based on various resins.
La machine de l'invention résout complètement le problème de réalisation de telles chapes sans qu'il y ait aucun ragréage ni aucune autre reprise à effec¬ tuer après le passage de cette machine. De plus, dans une réalisation particulière, la machine de l'invention rend possible de réaliser une chape à partir du pied d'un mur et elle permet, en ou¬ tre, de compenser des différences de planéité ou d'in¬ clinaison que présente le support sur lequel la chape est coulée.The machine of the invention completely solves the problem of producing such screeds without there being any leveling or any other recovery to be carried out after the passage of this machine. In addition, in a particular embodiment, the machine of the invention makes it possible to produce a screed from the foot of a wall and it makes it possible, in addition, to compensate for differences in flatness or inclination that presents the support on which the screed is poured.
Conformément à l'invention, la machine pour l'exécution de chapes en béton et produits analogues déversés d'une trémie comporte- un châssis supportant, par au moins deux rouleaux, une nappe sans fin dont la largeur correspond au moins à celle d'un distributeur de la trémie, des moyens d'entraînement de la nappe étant prévus pour que sa surface glisse sur la chape progressivement formée lors du déplacement du châssis qui la porte. Diverses autres caractéristiques de l'inven-According to the invention, the machine for the execution of concrete screeds and similar products discharged from a hopper comprises- a frame supporting, by at least two rollers, an endless ply whose width corresponds at least to that of a hopper distributor, means for driving the sheet being provided so that its surface slides on the screed progressively formed during the movement of the frame which carries it. Various other features of the invention

Des formes de réalisation de l'objet de l'in¬ vention sont représentées, à. titre d'exemples non lirαi- tatifs, aux dessins annexés.Embodiments of the object of the invention are shown in. title of non-reading examples, in the appended drawings.
La fig. 1 est une perspective de la machine pour l'exécution de chapes en béton et produits analo¬ gues selon l'invention.Fig. 1 is a perspective of the machine for the execution of concrete screeds and analogous products according to the invention.
La fig. 2 est une élévation latérale schéma- tique, partiellement en coupe, correspondant à la fig.l. La fig. 3 est une coupe-élévation, à plus grande échelle, d'un détail de réalisation.Fig. 2 is a schematic side elevation, partially in section, corresponding to fig.l. Fig. 3 is a sectional elevation, on a larger scale, of an embodiment detail.
La fig. 4 est une vue partielle analogue à la fig. 2 d'une variante. La fig. 5 est une perspective vue de trois quarts dessus illustrant une variante.Fig. 4 is a partial view similar to FIG. 2 of a variant. Fig. 5 is a perspective view from three quarters above illustrating a variant.
La fig. 6 est une élévation latérale par¬ tielle correspondant à la variante de la fig. 5 lors¬ qu'elle est réalisée conformément à la fig. 4. La machine représentée comporte un châssis 1 qui est muni d'un axe 2 constituant l'axe de rotation d'un rouleau 3. Le châssis 1 supporte, par une articu¬ lation 4, des bras pivotants 5 pouvant être commandés par au moins un vérin 6. Les bras pivotants 5 suppor- tent un rouleau tendeur 7 sur lequel passe une nappe sans fin 8, par exemple en caoutchouc éventuellement armé, dont la surface est lisse ou striée, selon l'as¬ pect que l'on désire conférer à une chape 9 à réaliser. De préférence les rouleaux 3 et 7, ainsi éventuellement que d'autres rouleaux qui peuvent être prévus pour ap¬ pliquer plus ou moins fortement la nappe sans fin 8 sur la chape en cours de formation, ne s'étendent pas sur toute la largeur de la nappe, mais laissent libre, de part et d'autre de celle-ci, un segment 8a_ comme le montre la fig. 3. Le dessous du segment 8a_ de la nappe présente également, comme cela est illustré par la fig.3 une légère pente et est arrondi comme illustré en 8b. De plus, il est avantageux, comme le montre aussi la fig. 3, que les parties d'extrémité 3a_ des rouleaux soient de diamètre progressivement décroissant.Fig. 6 is a partial side elevation corresponding to the variant of FIG. 5 when it is produced in accordance with FIG. 4. The machine shown comprises a chassis 1 which is provided with an axis 2 constituting the axis of rotation of a roller 3. The chassis 1 supports, by an articu¬ lation 4, pivoting arms 5 which can be controlled by at at least one actuator 6. The pivoting arms 5 support a tension roller 7 over which passes an endless ply 8, for example of possibly reinforced rubber, the surface of which is smooth or striated, depending on the aspect which is wishes to confer on a screed 9 to be produced. Preferably the rollers 3 and 7, as well as possibly other rollers which may be provided for applying more or less strongly the endless ply 8 on the screed being formed, do not extend over the entire width of the sheet, but leave free, on either side thereof, a segment 8a_ as shown in fig. 3. The underside of segment 8a_ of the water table also has, as illustrated in fig.3 a slight slope and is rounded as shown in 8b. In addition, it is advantageous, as also shown in FIG. 3, that the end portions 3a_ of the rollers are of progressively decreasing diameter.
Les mesures décrites ci-dessus sont destinées à rendre inapparant le joint illustré en 10 lorsque deux parties de chape sont coulées de manière contiguë comme cela est expliqué dans ce qui suit. Le châssis 1 supporte un moto-réducteur 11 pour l'entraînement d'un galet moteur 12 coopérant avec un rouleau de contre-pression 13 qui sont tous deux montés sur des bras 14 du châssis. Le galet moteur 12 et le rouleau de contre-pression 13 sont entraînés comme illustré par la fig. 2 pour faire avancer le nappe sans fin 8 dans le sens de la flèche f.. Le châssis 1 est muni, par exemple au—dessus du rouleau 3, d'un réservoir d'épandage 15 pouvant contenir de l'eau et/ou un produit de vernissage pour la surface de la chape en cours de réalisation. Le réservoir d'épandage est relié par un élément distributeur 16, par exemple une bande de feutre au-dessus de la nappe sans fin 8. Une vanne 17 permet de contrôler l'écoulement de l'eau et/ou du produit de vernissage. Le châssis 1 est relié par des axes 18 â une trémie 19 de largeur au plus égale à celle de la nappe 8 et contenant les constituants 20 de la chape 9, par exemple du béton. A sa partie inférieure, la tré¬ mie 19 est munie d'un dispositif mélangeur et de ferme¬ ture 21 permettant de contrôler le débit du béton lors de la formation de la chape et permettant aussi d'empê¬ cher l'écoulement du béton lorsque la chape doit être interrompue. Un vibreur réglable 22 est également porté par le châssis et est disposé entre la sortie de la trémie 19 et la nappe sans fin 8. Pour permettre de faire varier la charge par unité de surface que doit exercer la nappe sans fin 8, des contrepoids 23 réglables le long d'un support 24 sont disposés aux extrémités du châssis 1 qui est op¬ posé au rouleau tendeur 7. Par ailleurs, au moins un patin 25 est disposé à l'intérieur de la nappe sans fin pour prendre appui sur le côté de celle-ci qui porte sur la chape 9. Le patin 25 peut être poreux pour permettre l'insufflation d'air afin de créer un micro-coussin d'air entre le patin 25 et la nappe 8.The measures described above are intended to render the joint illustrated at 10 inapparent when two screed parts are poured contiguously as explained below. The chassis 1 supports a geared motor 11 for driving a drive roller 12 cooperating with a back pressure roller 13 which are both mounted on arms 14 of the chassis. The drive roller 12 and the back pressure roller 13 are driven as illustrated in FIG. 2 to advance the endless ply 8 in the direction of the arrow f. The chassis 1 is provided, for example above the roller 3, with a spreading tank 15 which may contain water and / or a varnish product for the surface of the screed being produced. The spreading tank is connected by a distributor element 16, for example a felt strip above the endless sheet 8. A valve 17 makes it possible to control the flow of water and / or of the varnishing product. The chassis 1 is connected by axes 18 to a hopper 19 of width at most equal to that of the sheet 8 and containing the constituents 20 of the yoke 9, for example concrete. At its lower part, the hopper 19 is provided with a mixing and closing device 21 making it possible to control the flow of concrete during the formation of the screed and also making it possible to prevent the flow of concrete when the screed must be interrupted. An adjustable vibrator 22 is also carried by the chassis and is disposed between the outlet of the hopper 19 and the endless ply 8. To allow the load to be varied by surface unit to be exerted by the endless ply 8, counterweights 23 adjustable along a support 24 are arranged at the ends of the frame 1 which is opposed to the tension roller 7. Furthermore, at least one pad 25 is arranged inside the endless sheet to rest on the side thereof which bears on the yoke 9. The shoe 25 can be porous to allow air to be blown in order to create a micro-air cushion between the pad 25 and the ply 8.
Comme l'illustre la fig. 1, le patin 25 est plus étroit que la nappe et sa conformation correspond à celle des rouleaux, c'est-à-dire que les bords latéraux du patin 25 sont légèrement relevés pour correspondre aux parties 3a du rouleau 3 de la fig. 3.As illustrated in fig. 1, the pad 25 is narrower than the ply and its conformation corresponds to that of the rollers, that is to say that the lateral edges of the pad 25 are slightly raised to correspond to the parts 3a of the roller 3 of FIG. 3.
Pour permettre le déplacement de l'ensemble décrit dans ce qui précède, il est prévu un élément trac¬ teur 26 (fig.l et 2) ou 27 (fig. 4). L'élément tracteur 26 est constitué par un tricycle comportant un moto-rë- ducteur 28 tandis que l'élément tracteur 27 selon la va¬ riante de la fig. 4 est muni, supplémentairement, d'un siège 29. La roue directrice 30 peut être commandée par un guidon 31 ou un volant 32.To allow the movement of the assembly described in the foregoing, there is provided a trac¬ tor element 26 (fig.l and 2) or 27 (fig. 4). The tractor element 26 is constituted by a tricycle comprising a gear motor 28 while the tractor element 27 according to the variant of FIG. 4 is additionally provided with a seat 29. The steering wheel 30 can be controlled by a handlebar 31 or a steering wheel 32.
L'élément tracteur peut faire partie intégran- te de l'ensemble décrit précédemment, c'est-à-dire qu'il peut être relié rigidement à la trémie 19. Il est pos¬ sible aussi, et cela est préféré, que la trémie 19 soit munie de moyens d'attelage 33, de préférence réglables en hauteur, le long d'une glissière 34 et que l'élément tracteur soit muni de barres d'attelage 35.The tractor element can be an integral part of the assembly described above, that is to say that it can be rigidly connected to the hopper 19. It is also pos¬ sible, and this is preferred, that the hopper 19 is fitted with coupling means 33, preferably adjustable in height, along a slide 34 and that the tractor element is fitted with coupling bars 35.
Cette dernière solution est préférée car elle permet de réduire la longueur de la machine en dételant l'élément tracteur et en démontant les contre-poids 23 ainsi que leurs supports 24. Comme le montre le dessin, les roues motrices 36 sont prévues pour que leur écartement soit inférieu à la largeur de la nappe sans fin 8.The latter solution is preferred because it makes it possible to reduce the length of the machine by uncoupling the tractor element and dismantling the counterweights 23 as well as their supports 24. As the drawing shows, the driving wheels 36 are provided so that their spacing is less than the width of the endless ply 8.
La machine fonctionne de la façon suivante : du béton, ou une autre matière, par exemple une résine chargée de fibres, de produits minéraux ou autres, est mis en place dans la trémie après que l'élément trac¬ teur 26 ou 27 ait été attelé. De l'eau ou un autre produit est mis en place dans le réservoir d'épandage 15 et le moto-réducteur 28 de l'élément tracteur est démarré pour entraîner la machine dans le sens de la flèche f-, le pilote 37 étant disposé, de préférence, comme illustré pour suivre le travail de la machine do le déplacement est évidemment très lent. Le moto-rédu teur 11 entraîne la nappe 8 dans le sens de la flèche f,, c'est-à-dire que le brin de cette nappe qui est en contact avec la chape 9 qui est progressivement formée et vibrée se déplace dans le même sens que celui de la formation de la nappe mais, à une vitesse supérieure, pour assurer le lissage de ladite nappe en même temps que l'apport éventuel sur celle-ci d'une pellicule d'eau ou d'un autre produit d'addition.The machine works as follows: concrete, or another material, for example a resin loaded with fibers, mineral products or the like, is put in place in the hopper after the trac¬ tor element 26 or 27 has been harnessed. Water or another product is placed in the spreading tank 15 and the gear motor 28 of the tractor element is started to drive the machine in the direction of arrow f-, the pilot 37 being arranged , preferably, as illustrated to follow the work of the machine do the movement is obviously very slow. The gear motor 11 drives the sheet 8 in the direction of the arrow f ,, that is to say that the strand of this sheet which is in contact with the yoke 9 which is gradually formed and vibrated moves in the same direction as that of the formation of the sheet but, at a higher speed, to ensure the smoothing of said sheet at the same time as the possible addition thereon of a film of water or of another product d 'addition.
La vitesse de déplacement de la nappe 8 est indépendante de celle à laquelle cette nappe est dépla cée par l'élément tracteur 26, 27 et peut être synchro- nisée par rapport à ce dernier.The speed of movement of the ply 8 is independent of that at which this ply is moved by the tractor element 26, 27 and can be synchronized with respect to the latter.
Lorsqu'une première chape a été déposée, la machine est tournée de 180° ou ramenée à la position de départ, mais décalée d'un pas par rapport à son tra jet initial, ce qui permet de couler une seconde chape contiguë 9a_ (fig. 3) qui est convenablement lissée étant donné que la nappe 8 recouvre le joint 10 sépa¬ rant les deux chapes; il en résulte que la surface du joint est elle-même lissée sans qu'une pression soit exercée sur le chape précédemment formée et donc sans détérioration de cette chape précédente. Suivant la fi_g. 5, le châssis 1 est supporté par un châssis auxiliaire 38, par exemple en forme de U qui est articulé par des axes 39 sur la trémie 19.When a first screed has been deposited, the machine is turned 180 ° or brought back to the starting position, but offset by one step compared to its initial path, which allows a second contiguous screed 9a_ to be poured (fig 3) which is suitably smoothed since the ply 8 covers the joint 10 separating the two yokes; it follows that the surface of the joint is itself smoothed without pressure being exerted on the previously formed screed and therefore without deterioration of this previous screed. According to the fi_g. 5, the chassis 1 is supported by an auxiliary chassis 38, for example in the shape of a U which is articulated by pins 39 on the hopper 19.
La trémie 19 est supportée par des patins 40 dont un seul est visible à la fig. 5, patins qui peuvent être de très faible largeur et qui s'étendent de manière à ne pas prendre appui sur la partie de chape 9 qui a été formée au préalable.The hopper 19 is supported by pads 40 of which only one is visible in FIG. 5, pads which can be very narrow and which extend so as not to bear on the yoke part 9 which has been formed beforehand.
Le châssis auxiliaire 38 comporte des moyens illustrés par un levier 41 permettant de faire basculer ce châssis auxiliaire suivant la flèche f_2 pour le- sou¬ lever ainsi que le châssis 1 afin d'amener les châssis 38 et éventuellement 1 en position verticale, ce qui permet que la sortie de la trémie 19 puisse venir con- tre un mur ou un autre élément à partir duquel la chape 9 doit être formée.The auxiliary chassis 38 comprises means illustrated by a lever 41 making it possible to tilt this auxiliary chassis according to the arrow f_ 2 to lift it and the chassis 1 so as to bring the chassis 38 and possibly 1 into a vertical position, this which allows the outlet of the hopper 19 to come against a wall or another element from which the yoke 9 must be formed.
Le moyen de levage 41 comporte des moyens d'ac couplement 42 reliés à des roues 43 permettant de soule¬ ver l'ensemble de la machine au-dessus des patins 40 par exemple pour le transport d'un point à un autre.The lifting means 41 comprises coupling means 42 connected to wheels 43 making it possible to lift the whole of the machine above the pads 40 for example for transport from one point to another.
Le châssis auxiliaire 38 comporte une barre transversale 44 par rapport à laquelle peut être dépla¬ cée une barre coulissante 45 portant par un bras 46 le support 47 d'une lame souple 48. Le dessin montre que la lame souple 48 peut être déplacée pour être amenée dans une position pour laquelle elle recouvre à la fois au moins partiellement la chape 9 déjà coulée et la chape 9^ en cours d'exécution.The auxiliary frame 38 comprises a transverse bar 44 with respect to which a sliding bar 45 can be moved 45 carrying by an arm 46 the support 47 of a flexible blade 48. The drawing shows that the flexible blade 48 can be moved to be brought into a position for which it covers both at least partially the yoke 9 already cast and the yoke 9 ^ in progress.
Le support 47 est porté, d'une part, par le bras 46 et, d'autre part, par une barre de guidage 49 qui est fixée au châssis 1 par* un dispositif 50 régla¬ ble en hauteur. De cette manière, l'inclinaison de la barre 47 et, par conséquent, de la lame souple 48 peu¬ vent être réglées angulairement, ce qui permet de tenir compte d'une pente éventuelle du sol sur lequel reposent les patins 40 qui eux-mêmes sont avantageusement régl bles en hauteur par rapport au châssis auxiliaire 38.The support 47 is carried, on the one hand, by the arm 46 and, on the other hand, by a guide bar 49 which is fixed to the chassis 1 by * a device 50 adjustable in height. In this way, the inclination of the bar 47 and, consequently, of the flexible blade 48 can be adjusted angularly, which makes it possible to take account of a possible slope of the ground on which rest. the pads 40 which themselves are advantageously adjustable in height relative to the auxiliary frame 38.
Outre ce qui précède il est avantageux que l machine comporte, entre le réservoir d'épandage 15 et la trémie 19, une trémie auxiliaire 51 contenant un produit d'addition par exemple de la poudre de carbo- rundum ou autre produit conférant à la chape une qual particulière.In addition to the above, it is advantageous that the machine comprises, between the spreading tank 15 and the hopper 19, an auxiliary hopper 51 containing an additive product, for example, carbonundum powder or other product giving the screed a particular quality.
L'invention n*est pas limitée aux exemples réalisation, représentés et décrits en détail, car di verses modifications peuvent y être apportées sans sortir de son cadre. En particulier, des moyens de réglage en hauteur de la trémie 19 peuvent être prévu The invention is not limited to the exemplary embodiments, shown and described in detail, since various modifications can be made thereto without departing from its scope. In particular, means for adjusting the height of the hopper 19 can be provided
