Avoid this danger State of the art and disadvantages
Many devices have been provided to remedy the tilting of the formwork and, in particular, these solutions have been summarized in patent application 83.00295.
La présente invention prévoit une solution différente. The present invention provides a different solution.
Exposé de l'invention
L'invention prévoit une solution par lest dsau moins une des poutres de raidissement qui contrebalance l'effet du poids important de la face coffrante. Le lest est suspendu à la poutre par un lien, avec -jeu, d'une longueur telle que, lors de la manoeuvre de descente de l'ensemble vers le sol de l'appareil de levage, le lest repose sur le sol avant la banche et ses poutres raidissement et que le lest n'intervienne qu'à l'amorce d'un mouvement de basculement du c6té de la face coffrante.Statement of the invention
The invention provides a ballast solution of at least one of the stiffening beams which counterbalances the effect of the significant weight of the shuttering face. The ballast is suspended from the beam by a link, with -game, of a length such that, during the maneuver of descent of the assembly towards the ground of the lifting device, the ballast rests on the ground before the panel and its stiffening beams and the ballast only intervenes at the start of a tilting movement on the side of the formwork face.
Il faut éviter des déplacements intempestifs du lest qui s'adapte a des ensembles existants. Pour cela on s'arrange pour les guider verticalement sur un montant d'une poutre de raidissement vertical. Avoid unwanted movements of the ballast, which adapts to existing assemblies. For this we arrange to guide them vertically on an upright of a vertical stiffening beam.
Pour que ce lest ait le maximum d'efficacité, on le situe à la plus grande distance possible de la face coffrante. For this ballast to have the maximum efficiency, it is located at the greatest possible distance from the formwork face.
Une particularité importante de l'invention réside dans le fait que le lest est suspendu par des liens souples par exemple des channes. An important feature of the invention lies in the fact that the ballast is suspended by flexible links, for example chains.
Une autre particularité, devant faciliter les petits déplacements de la banche pour son réglage, consiste à prévoir des roues d'appui sur le sol, les deux roues ayant leurs axes horizontaux sensiblement parallèles à la face coffrante. De cette façon, le "mou" des chaines permet des petits déplacements de la banche tandis que les roues sur lesquelles repose le lest permet des déplacements horizontaux beaucoup plus importants de la banche
Solution au problème, avantages et résultats industriels
I1 est facile de comprendre que le lest déplace le barycentre de l'ensembte. Cependant, le partie caractéristique de l'invention réside dans l9emploi de lien de liaison du lest > la poutre présentant un certain jeu.Another particular feature, which should facilitate small movements of the formwork for its adjustment, consists in providing support wheels on the ground, the two wheels having their horizontal axes substantially parallel to the shuttering face. In this way, the "slack" of the chains allows small displacements of the form while the wheels on which the ballast rests allows much greater horizontal displacements of the form
Solution to the problem, advantages and industrial results
It is easy to understand that the ballast displaces the barycenter of the assembly. However, the characteristic part of the invention resides in the use of ballast connection link> the beam having a certain clearance.
Grâce à cela, on soulève d'abord l'ensemble banche poutres verticales sans lever tout d'abord le lest jusqu'au moment où les liens avec jeu se tendent. C'est seulement après que l'on soulève le lest. Ceci a plusieurs avantages.Thanks to this, the vertical beams assembly is first lifted without first lifting the ballast until the links with play are tightened. It is only after lifting the ballast. This has several advantages.
- tout d'abord, on limite le poids soulevé ou abaissé par la grue de chantier - ensuite, on limite les chocs lors du repos de l'ensemble sur un plancher ou un sol quelconque - ensuite, on évitE les efforts exagérés sur les structures inrérieures de l'ensemble banche-poutres verticales - enfin, comme on l'a expliqué ci-dessus, on peut se permettre à la fois de petits déplacements sans bouger les lests et déplus grands déplacements grâce aux roulettes.- first of all, we limit the weight raised or lowered by the site crane - then, we limit the shocks during the rest of the assembly on a floor or any ground - then, we avoid the exaggerated efforts on the structures of the panel-vertical beam assembly - finally, as explained above, we can allow ourselves both small movements without moving the ballast and larger displacements thanks to the rollers.
L'invention sera mieux comprise à l'aide de la description suivante qui en donne un exemple non limitatif de réalisation pratique et qui est illustré par les dessins joints. The invention will be better understood with the aid of the following description which gives a nonlimiting example of practical embodiment thereof and which is illustrated by the accompanying drawings.

Description d'un mode de réalisation
Le dispositif de l'invention est prévu pour s'associer à un ensemble banche-poutres de raidissement vertical (2). Ces poutres (2) comportent un montant (3), le plus éloigné de la banche (1), dont la partie supérieure comporte une attache (4) à laquelle se fixent des cha-ines de suspension (5) et (6) d'un lest (7).Description of an embodiment
The device of the invention is intended to be associated with a panel-vertical stiffening beams (2). These beams (2) comprise an upright (3), the furthest from the form (1), the upper part of which comprises a fastener (4) to which are attached suspension chains (5) and (6) d 'a ballast (7).
Suivant la forme d'exécution de l'invention le lest (7) a une forme, en gros, parallèlépipèdique avec une rainure (8) destinée à jouer le rôle de coulisseau le long du montant (3), servant alors de glissière. En effet, les chaînes (5) et (6) ont une longueur telle que, lorsque l'ensemble est suspendu au dessus du sol (9) (figure 3), la partie inférieure dudit lest (7) se situe à un niveau inférieur aux parties plus basses de l'ensemble banche ( poutre de raidissement vertical (2). Ceci est réalisé lorsque l'on suspend l'ensemble par des élingues (10) et (11) et qu'on monte ou qu'on abaisse suivant la flèche (12). According to the embodiment of the invention the ballast (7) has a shape, roughly, parallelepipedal with a groove (8) intended to play the role of slide along the upright (3), then serving as a slide. Indeed, the chains (5) and (6) have a length such that, when the assembly is suspended above the ground (9) (Figure 3), the lower part of said ballast (7) is located at a lower level to the lower parts of the panel assembly (vertical stiffening beam (2). This is achieved when the assembly is suspended by slings (10) and (11) and is raised or lowered according to the arrow (12).
Lorsqu'on repose l'ensemble sur le sol (9) (figure 4), le crochet de la grue suit le mouvement de la flèche (13) et c'est d'abord le lest (7) qui repose sur le sol (9) avant que ce ne soit l'ensemble banche (1)poutre de raidissement vertical (2). When the assembly is placed on the ground (9) (Figure 4), the crane hook follows the movement of the boom (13) and it is first the ballast (7) which rests on the ground ( 9) before it is the panel assembly (1) vertical stiffening beam (2).
On enlève les élingues (10) et (11) et si un coup de vent survient, comme matérialisé par la flèche (14), il peut dangeureusement faire basculer l'ensemble banche (l)-poutre de raidissement vertical (2) vers l'avant, comme cela est représenté a la figure 5. Dans ce cas, les chaînes de suspension (5) et (6) se tendent dans le sens de la flèche (15) et retiennent la poutre (2) de manière à empêcher l'ensemble de basculer vers la face coffrante. We remove the slings (10) and (11) and if a gust of wind occurs, as materialized by the arrow (14), it can dangerously tilt the whole panel (l) - vertical stiffening beam (2) towards the 'front, as shown in Figure 5. In this case, the suspension chains (5) and (6) tighten in the direction of the arrow (15) and hold the beam (2) so as to prevent the 'set to tilt towards the shuttering face.
Une autre particularité de l'invention réside dans la présence de roues (16, 17) à la base du lest (7). Les roues (16, 17) ont des axes horizontaux parallèles à la banche (1) et à sa face coffrante. De cette manière, on peut éloigner ou rapprocher le lest (7) de la banche, d'une distance qui est permise par le jeu ou le mou que l'on a laissé aux chaînes de suspension (5) et (6) Another feature of the invention lies in the presence of wheels (16, 17) at the base of the ballast (7). The wheels (16, 17) have horizontal axes parallel to the form (1) and to its form face. In this way, the ballast (7) can be moved away or closer to the form, by a distance which is allowed by the play or the slack which has been left to the suspension chains (5) and (6).
