The device (2) has two parallelograms (3) hooked at slings, and wind stabilization units formed by connecting rods (4), where each connecting rod acts on a form panel (3') of one of the parallelograms. Feet (5) are fixed on heads of form panels (1) by an anchoring device (6), where each foot forms an extension from a side of one of the parallelograms. A lateral displacement unit permits to laterally displace one form panel.

Description

La présente invention concerne le domaine de la manutention de certaines charges dans le bâtiment et les travaux publics, en particulier des banches et a pour objet un dispositif de stabilisation et de manutention pourvu d'un moyen de déplacement latéral d'une banche seule.The present invention relates to the field of the handling of certain loads in the building and public works, in particular banches and has for object a stabilization and handling device provided with a means of lateral displacement of a single form.

La réalisation de voiles de béton, dans le domaine du bâtiment et des travaux publics, s'effectue généralement par mise en oeuvre de banches de coffrage qui consistent en des panneaux de coffrage munis d'armatures destinées à coopérer avec des moyens d'étaiement, et de serrage. Ces banches, qui présentent généralement des surfaces assez importantes, sont en conséquence d'un poids relativement élevé et nécessitent d'être manutentionnées exclusivement au moyen de grues.The production of concrete sails, in the field of building and public works, is generally carried out by implementing shuttering formwork which consist of formwork panels provided with reinforcements intended to cooperate with shoring means, and tightening. These rafts, which generally have fairly large surfaces, are consequently of relatively high weight and need to be handled exclusively by means of cranes.

Afin de permettre une manutention de telles banches par couple et de réaliser plus rapidement la mise en place des coffrages, ainsi que le décoffrage, il a été prévu de mettre en oeuvre des dispositifs permettant ladite manutention, ainsi que la stabilisation des banches en position, lors de la préparation des coffrages, ainsi que pour le coulage du béton proprement dit.In order to allow the handling of such bundles per couple and to achieve faster establishment of formwork, as well as stripping, it has been planned to implement devices for said handling, and the stabilization of the panels in position, during the preparation of the forms, as well as for the concrete pouring itself.

Actuellement, il existe à cet effet différents dispositifs permettant de maintenir deux banches de manière parallèle entre elles et consistant essentiellement en des double parallélogrammes pouvant être accrochés à des élingues d'un palonnier. Il est également connu, notamment par FR-A-2 853 924 , de pourvoir ces dispositifs de moyens de stabilisation au vent sous forme de biellettes agissant chacune sur un bras d'un parallélogramme et permettant d'éviter des déplacements intempestifs mutuels des banches accrochées audit dispositif.Currently, there are for this purpose different devices for maintaining two sides parallel to each other and consisting essentially of double parallelograms that can be hooked to slings of a rudder. He is also known, particularly by FR-A-2,853,924 providing these devices with wind stabilization means in the form of rods each acting on an arm of a parallelogram and making it possible to avoid mutual inadvertent movements of the boards attached to said device.

Ces dispositifs connus permettent de répondre de manière satisfaisante aux problèmes de manutention et de stabilisation au vent et peuvent généralement être mis en oeuvre de manière relativement simple et rapide.These known devices make it possible to respond satisfactorily to handling and wind stabilization problems and can generally be implemented in a relatively simple and rapid manner.

Cependant, dans le cas de réalisation de murs ou voiles parallèles s'étendant à relativement courte distance l'un de l'autre, en particulier pour déterminer des zones de circulation, il se pose un problème d'encombrement dû au fait que l'écartement des banches s'effectue de manière symétrique, de sorte que le dégagement et la mise en place d'un ensemble de banches au moyen de ces dispositifs deviennent difficiles et nécessitent de longues manoeuvres entraînant des frais supplémentaires. Ce problème se pose également avec le dispositif selon FR-A-2 853 924 , qui prévoit, aux extrémités des branches inférieures des parallélogrammes un prolongement en forme de levier pour l'accrochage d'une élingue ou d'une chaîne. Ainsi, il est possible de réaliser un décoffrage automatique. Toutefois, un dégagement d'une seule banche, parallèlement au mur, avec maintien en position de l'autre banche ne peut être obtenu, par exemple par accrochage d'un levier seulement et traction sur ce dernier. En effet, des essais ont démontré qu'une telle action unilatérale n'avait aucun effet et que l'ensemble restait bloqué en position de coffrage, les deux parallélogrammes du dispositif restant parfaitement rigides et symétriques du fait même de leur mode d'assemblage sur le fût central.However, in the case of realization of walls or parallel sails extending relatively short distance from one another, in particular to determine traffic areas, there is a problem of congestion due to the fact that the separation of the banches is carried out symmetrically, so that the clearance and the installation of a set of trusses by means of these devices become difficult and require lengthy maneuvers leading to additional costs. This problem also arises with the device according to FR-A-2,853,924 which provides, at the ends of the lower branches of the parallelograms, a lever-like extension for hooking a sling or a chain. Thus, it is possible to achieve automatic stripping. However, a clearance of one side, parallel to the wall, with holding in position the other side can not be obtained, for example by hooking a lever only and traction on the latter. Indeed, tests have shown that such a unilateral action had no effect and that the whole remained blocked in formwork position, the two parallelograms of the device remaining perfectly rigid and symmetrical because of their very same way of assembly on the central shaft.

La présente invention a pour but de pallier les inconvénients des dispositifs de stabilisation et de manutention de banches existant à ce jour en proposant un tel dispositif de stabilisation et de manutention permettant une mise en oeuvre plus simple et plus rapide, ainsi que des manutentions facilitées.The present invention aims to overcome the disadvantages of stabilization devices and handling of existing docks by proposing such a stabilization and handling device for a simpler and faster implementation, and easier handling.

A cet effet, le dispositif de stabilisation et de manutention de banches conforme à l'invention, qui est essentiellement constitué par des double parallélogrammes pouvant être accrochés à des élingues et par un moyen de stabilisation au vent formé par des biellettes agissant chacune sur une branche d'un parallélogramme, est caractérisé en ce qu'il est pourvu d'un moyen de décoffrage et de déplacement latéral d'une banche seule, l'autre banche restant immobile.For this purpose, the stabilization device and handling of docks according to the invention, which consists essentially of double parallelograms that can be hooked to slings and a wind stabilization means formed by rods each acting on a branch of a parallelogram, is characterized in that it is provided with a means of formwork and lateral displacement of one side only, the other branch remaining immobile.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en élévation frontale d'un dispositif de stabilisation et de manutention conforme à l'invention en position de service de deux banches, et
  • la figure 2 est une vue analogue à celle de la figure 1 représentant le dispositif en position d'écartement des banches avant enlèvement ou avant mise en place.
The invention will be better understood, thanks to the following description, which refers to a preferred embodiment, given by way of non-limiting example, and explained with reference to the attached schematic drawings, in which:
  • the figure 1 is a front elevational view of a stabilization and handling device according to the invention in the service position of two side panels, and
  • the figure 2 is a view similar to that of the figure 1 representing the device in the spreading position of the panels before removal or before implementation.

Les figures 1 et 2 des dessins annexés représentent un ensemble de banches 1 reliées à un dispositif de stabilisation et de manutention 2, qui est essentiellement constitué par des double parallélogrammes 3 pouvant être accrochés à des élingues et par un moyen de stabilisation au vent formé par des biellettes 4 agissant chacune sur une branche 3' d'un parallélogramme 3. Ce dispositif de stabilisation et de manutention 2 comporte, en outre, des pieds 5 de fixation sur les têtes des banches 1 par l'intermédiaire de dispositifs d'ancrage 6, ces pieds 5 formant chacun un prolongement d'un côté de l'un des parallélogrammes 3. De manière connue, le dernier côté des double parallélogrammes 3 est constitué par un fût central 7 relié aux extrémités des bras supérieurs et inférieurs des parallélogrammes 3, du côté opposé à celui de liaison aux pieds 5. Ce fût central 7 assure une symétrie à l'ouverture du dispositif 2 et ainsi du coffrage formé par les banches 1, en correspondance avec les biellettes 4 formant le moyen de stabilisation au vent, en garantissant le synchronisme de fonctionnement de ces dernières, par l'intermédiaire d'un coulisseau 8 guidé en déplacement, avec un jeu important permettant un débattement important, dans ledit fût central 7.The figures 1 and 2 appended drawings represent a set of boards 1 connected to a stabilization and handling device 2, which essentially consists of double parallelograms 3 that can be hooked to slings and wind stabilization means formed by rods 4 each acting on a branch 3 'of a parallelogram 3. This stabilization and handling device 2 comprises, in addition, fixing feet 5 on the heads of the panels 1 by means of anchoring devices 6, these legs 5 each forming an extension of one side of one of the parallelograms 3. In known manner, the last the side of the double parallelograms 3 is constituted by a central shaft 7 connected to the ends of the upper and lower arms of the parallelograms 3, on the side opposite to that of the connection to the feet 5. This central shaft 7 ensures a symmetry at the opening of the device 2 and and the formwork formed by the panels 1, in correspondence with the rods 4 forming the wind stabilizing means, ensuring the synchronism of operation of these rnières, via a slider 8 guided in displacement, with a large clearance allowing a large clearance, in said central shaft 7.

Conformément à l'invention, pour permettre un déplacement d'ouverture d'un seul côté du coffrage réalisé par une paire de banches, ce sans modifier la position de l'autre banche, le dispositif de stabilisation et de manutention 2 est pourvu d'un moyen de décoffrage et de déplacement latéral d'une banche seule, l'autre banche restant immobile.According to the invention, to allow an opening movement of one side of the formwork made by a pair of panels, without changing the position of the other side, the stabilizing and handling device 2 is provided with a means of formwork and lateral displacement of one side only, the other side remaining motionless.

De préférence, comme le montrent les figures 1 et 2 des dessins annexés, le moyen de décoffrage et de déplacement latéral d'une banche seule, l'autre banche restant immobile, consiste, d'une part, en un prolongement en forme de levier 9 de l'une des branches inférieures 3' des parallélogrammes 3, à son extrémité tournée vers l'extérieur, ce prolongement en forme de levier étant muni d'un dispositif d'accrochage 10 pour une élingue ou une chaîne 11 et, d'autre part, en des paliers oblongs verticaux 12 de guidage des axes d'articulation 13 des extrémités tournées vers l'extérieur, respectivement de la branche inférieure 3' du parallélogramme 3 pourvue du prolongement en forme de levier muni du dispositif d'accrochage 10 et de la branche supérieure 3' correspondante du parallélogramme 3 et, d'autre part, en une biellette 14 de liaison de ces deux axes d'articulation 13 entre eux.Preferably, as shown by figures 1 and 2 of the accompanying drawings, the means of formwork and lateral displacement of one side only, the other side remaining immobile, consists, on the one hand, in a prolongation in the form of a lever 9 of one of the lower branches 3 'of parallelograms 3, at its end facing outwards, this extension in the form of a lever being provided with an attachment device 10 for a sling or a chain 11 and, secondly, in vertical oblong guide bearings 12 hinge pins 13 of the outwardly facing ends, respectively of the lower leg 3 'of the parallelogram 3 provided with the lever-shaped extension provided with the attachment device 10 and the corresponding upper branch 3' of the parallelogram 3 and on the other hand, a link 14 connecting these two hinge pins 13 between them.

Ainsi, il est possible d'agir directement sur l'extrémité de la branche inférieure 3' par l'intermédiaire d'une élingue 11 ou d'une chaîne accrochée à son autre extrémité au crochet d'une grue de levage (non représentée), pour réaliser un écartement automatique de la banche correspondante lors d'une manoeuvre de décoffrage.Thus, it is possible to act directly on the end of the lower branch 3 'by means of a sling 11 or a chain hooked at its other end to the hook of a hoisting crane (no shown), to achieve an automatic spacing of the corresponding form during a formwork maneuver.

De préférence, le prolongement en forme de levier 9 est légèrement coudé vers l'extérieur du dispositif 2 pour former, avec le pied 5 correspondant de celui-ci, un angle différent de celui de la branche inférieure 3' qu'il prolonge.Preferably, the extension in the form of lever 9 is slightly bent outwardly of the device 2 to form, with the corresponding foot 5 thereof, an angle different from that of the lower branch 3 'that it extends.

Grâce à ce mode de réalisation, il est possible, par accrochage d'une élingue 11 ou d'une chaîne à l'extrémité libre du prolongement en forme de levier 9, et par action seulement sur cette élingue ou chaîne 9, de ne déplacer que la banche 1 en prolongement du pied 5 correspondant au levier 9, lorsque deux banches sont posées sur une surface plane.With this embodiment, it is possible, by hooking a sling 11 or a chain at the free end of the extension in the form of lever 9, and by action only on this sling or chain 9, to move that the box 1 in extension of the foot 5 corresponding to the lever 9, when two boards are placed on a flat surface.

En effet, l'action sur l'élingue ou la chaîne 9 entraînera, dans un premier temps, uniquement un déplacement du prolongement en forme de levier 9 de l'extrémité de la branche inférieure 3' et donc un pivotement de l'ensemble de cette branche inférieure 3' autour de son axe d'articulation sur le fût central 7. Ce pivotement de la branche inférieure 3', pourvue du prolongement en forme de levier 9, est rendue possible par la prévision du palier oblong vertical 12 correspondant de guidage de l'axe d'articulation 13 de l'extrémité tournée vers l'extérieur de ladite branche inférieure 3'. Il s'ensuit, un mouvement d'écartement correspondant du pied 5 et de la banche 1. Or, comme la branche inférieure 3' du parallélogramme 3 est reliée, par son axe d'articulation 13 à l'axe d'articulation 13 de la branche supérieure 3' dudit parallélogramme 3, par l'intermédiaire de la biellette 14 de liaison, les deux branches 3' sont pivotées simultanément, de sorte que le mouvement d'écartement de la banche 1 est un mouvement parallèle au mur et à l'autre banche 1, qui reste en position contre ledit mur.Indeed, the action on the sling or the chain 9 will initially cause only a displacement of the extension in the form of a lever 9 of the end of the lower branch 3 'and thus a pivoting of the assembly of this lower branch 3 'about its hinge axis on the central shaft 7. This pivoting of the lower branch 3', provided with the extension in the form of a lever 9, is made possible by the provision of the vertical oblong bearing 12 corresponding guide of the hinge pin 13 of the end facing outwardly of said lower branch 3 '. It follows, a corresponding spacing movement of the foot 5 and the block 1. However, as the lower branch 3 'of the parallelogram 3 is connected by its axis of articulation 13 to the axis of articulation 13 of the upper branch 3 'of said parallelogram 3, through the connecting rod 14 connecting, the two branches 3' are pivoted simultaneously, so that the spacing movement of the form 1 is a parallel movement to the wall and the l Another form 1, which remains in position against said wall.

Une poursuite de la traction sur l'élingue ou la chaîne 9 permettra d'augmenter l'écartement de la banche 1 correspondante par rapport au mur, tout en laissant l'autre banche 1 en application contre l'autre face de ce mur.Continued traction on the sling or chain 9 will increase the spacing of the corresponding form 1 relative to the wall, while leaving the other side 1 against the other side of the wall.

Un tel déplacement présente un intérêt particulier dans le cas où l'espace disponible pour les manoeuvres d'installation d'un coffrage et de décoffrage doivent être effectuées dans un espace réduit, par exemple lorsque le mur à ériger est situé près d'un autre mur déjà réalisé.Such a displacement is of particular interest in the case where the space available for the operations of installation of a formwork and formwork must be carried out in a small space, for example when the wall to erect is located near another wall already realized.

Ainsi, lors de la préparation d'un coffrage, un ensemble de banches peut être amené, au moyen du dispositif de stabilisation et de manutention 2, dans la position représentée à la figure 1, par exemple en alignant directement la banche 1 (de gauche sur le dessin) au droit de la face du mur à ériger, puis d'ouvrir l'espace entre les banches 1, par accrochage d'une élingue ou chaîne 11 au dispositif 10 du levier 9. Le ferraillage du mur peut alors être réalisé, puis la banche 1 préalablement écartée au moyen du levier 9 peut être amenée dans sa position de service par simple traction au moyen d'une grue sur le fût central 7. Du fait que la première banche préalablement disposée au droit de la face du mur à ériger et déjà dans sa position de service, l'actionnement du dispositif 2 par l'intermédiaire du fût central 7 aura pour effet de fermer le coffrage par déplacement de l'autre banche 1 seule, en repliant les deux parallélogrammes de part et d'autre dudit fût central 7 pour les amener dans la configuration représentée à la figure 1 des dessins annexés. Les paliers oblongs verticaux 12 de guidage des axes d'articulation 13 des extrémités tournées vers l'extérieur des branches inférieure et supérieure 3' du parallélogramme 3 permettent, dans ce cas, un positionnement préalable de la banche 1 correspondante, parallèlement à la banche 1 déjà en position, puis le glissement des axes 13 vers la partie inférieure des paliers oblongs verticaux 12, dans la position correspondant à celle de coffrage.Thus, during the preparation of a formwork, a set of panels can be brought, by means of the stabilization and handling device 2, in the position shown in FIG. figure 1 , for example in directly aligning the section 1 (left of the drawing) to the right of the face of the wall to erect, then open the space between the panels 1, by hooking a sling or chain 11 to the device 10 of the lever 9. The reinforcement of the wall can then be made, then the block 1 previously separated by means of the lever 9 can be brought into its service position by simply pulling by means of a crane on the central shaft 7. Because the first form beforehand arranged to the right of the face of the wall to erect and already in its operating position, the actuation of the device 2 through the central shaft 7 will have the effect of closing the formwork by moving the other wall 1 only, in folding the two parallelograms on either side of said central shaft 7 to bring them into the configuration shown in FIG. figure 1 attached drawings. The vertical oblong bearings 12 for guiding the hinge pins 13 of the outwardly facing ends of the lower and upper branches 3 'of the parallelogram 3 allow, in this case, a prior positioning of the corresponding form 1, parallel to the form 1 already in position, then the sliding of the axes 13 towards the lower part of the vertical oblong bearings 12, in the position corresponding to that of formwork.

Pour réaliser le décoffrage, il suffira d'actionner à nouveau le levier 9 au moyen d'une grue pour déplacer la banche 1 correspondante, l'ensemble des deux banches pouvant alors être soulevées par la même grue agissant sur le coulisseau 8 du dispositif 2.To achieve the formwork, it will be sufficient to operate again the lever 9 by means of a crane to move the corresponding form 1, all of the two panels can then be lifted by the same crane acting on the slider 8 of the device 2 .

Ainsi, l'ensemble du coffrage d'un mur pourra être retiré, de sa position de coffrage sans déplacement transversal de l'une des banches, ce qui est particulièrement intéressant lorsque l'espace disponible entre le mur ainsi réalisé et des éléments de construction déjà en place est très restreint.Thus, all the formwork of a wall can be removed from its formwork position without transverse displacement of one of the panels, which is particularly interesting when the space available between the wall thus produced and building elements already in place is very restricted.

L'invention n'a été décrite qu'à propos d'un seul dispositif de stabilisation et de manutention. Cependant, il est bien évident que, tant pour des raisons de sécurité que pour des raisons d'équilibrage et de positionnement lors de la manutention, deux dispositifs conformes à l'invention devront être utilisés pour la manutention d'au moins une paire de banches parallèles.The invention has been described only in connection with a single stabilization and handling device. However, it is obvious that, both for reasons of safety and for reasons of balancing and positioning during handling, two devices according to the invention will have to be used for the handling of at least one pair of boards parallel.

Grâce à l'invention, il est possible de réaliser un dispositif de stabilisation et de manutention de banches permettant de réaliser un déplacement d'ouverture du coffrage d'un seul côté, de sorte que l'espace nécessaire pour la manoeuvre d'une paire de banche peut être réduit d'un côté du mur à ériger à une largeur dépassant à peine l'encombrement total en largeur d'une banche. En effet, lors d'un décoffrage automatique, celui-ci s'effectuera uniquement sur un côté du mur érigé, l'ensemble de banches pouvant ensuite être dégagé verticalement.Thanks to the invention, it is possible to produce a stabilization device and handling of panels allowing to make a displacement opening of the formwork on one side, so that the space required for the maneuvering of a pair can be reduced on one side of the wall to be erected to a width hardly exceeding the total space requirement in width of a form. Indeed, during an automatic demoulding, it will be carried out only on one side of the erected wall, the set of banches can then be cleared vertically.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
