Description
Dispositif de soulèvement d'une charge, et ensemble de deux dispositifs de coffrage reliés par deux tels dispositifs de soulèvement Device for lifting a load, and set of two shuttering devices connected by two such lifting devices
La présente invention est relative à un dispositif de soulèvement d'une charge en deux points espacés de cette charge, du type comprenant, pour chacun desdits points, au moins un organe rigide de soulèvement relié par sa base audit point, les moyens de liaison de chaque organe rigide audit point étant adaptés pour permettre une inclinaison dudit organe de soulèvement vers l'autre desdits points dans le plan vertical défini par les deux points. L'invention s'applique en particulier à la manutention des banches de coffrage de béton. The present invention relates to a device for lifting a load at two points spaced from this load, of the type comprising, for each of said points, at least one rigid lifting member connected by its base to said point, the connecting means of each rigid member at said point being adapted to allow an inclination of said lifting member to the other of said points in the vertical plane defined by the two points. The invention applies in particular to the handling of concrete formwork panels.
Classiquement, pour couler des parois verticales en béton, on délimite la paroi à l'aide de paires de dispositifs de coffrage dont les faces coffrantes sont tournées l'une vers l'autre. Ces dispositifs de coffrage peuvent être considérés par une banche ou par plusieurs banches, juxtaposées et/ou superposées, assemblées ensemble. Conventionally, for casting vertical concrete walls, the wall is delimited by pairs of formwork devices whose form faces are turned towards one another. These formwork devices can be considered by a panel or by several panels, juxtaposed and / or superimposed, assembled together.
Ces dispositifs de coffrage sont maintenus à la verticale de leur plan d'appui, notamment à l'aide d'étais placés à l'arrière de ces dispositifs de coffrage. Outre des étais, il est connu d'associer ces deux dispositifs de coffrage à deux à l'aide de deux dispositifs de liaison ou portiques (FR-A-2 808 041) fixés sur la rive supérieure des banches. Chaque dispositif de liaison se présente sous la forme d'un compas comprenant une tête supérieure centrale et deux branches. Sur la tête sont articulées deux paires de bielles parallèles constituant lesdits organes rigides de soulèvement. L'autre extrémité de chaque paire de bielles est articulée sur une chape. Une tige verticale traverse la tête. Deux bielles d'écartement sont articulées d'une part à l'extrémité inférieure de cette tige, et d'autre part en un point intermédiaire de la bielle inférieure de chaque paire de bielles parallèles. Ainsi, le soulèvement de la tige verticale provoque, grâce à l'agencement articulé décrit ci-dessus, l'ouverture du compas et l'écartement des deux chapes parallèlement à elles-mêmes. These formwork devices are held vertically to their support plane, in particular using props placed at the rear of these formwork devices. In addition to props, it is known to combine these two formwork devices with two using two connecting devices or gantries (FR-A-2 808 041) attached to the upper bank of the panels. Each connecting device is in the form of a compass comprising a central upper head and two branches. On the head are articulated two pairs of parallel connecting rods constituting said rigid lifting members. The other end of each pair of rods is articulated on a yoke. A vertical stem crosses the head. Two spacing rods are articulated on the one hand at the lower end of this rod, and secondly at an intermediate point of the lower link of each pair of parallel rods. Thus, the lifting of the vertical rod causes, thanks to the articulated arrangement described above, the opening of the compass and the spacing of the two yokes parallel to themselves.
Les deux portiques sont espacés l'un de l'autre le long du bord supérieur des dispositifs de coffrage. Par suite, le soulèvement simultané des deux tiges de suspension au moyen de deux élingues convergeant vers le haut vers un crochet de grue commun, tend à incliner les deux portiques l'un vers l'autre. The two gantries are spaced from each other along the upper edge of the formwork devices. As a result, the simultaneous lifting of the two suspension rods by means of two slings converging upwards to a common crane hook, tends to incline the two gantries towards each other.
Pour éviter que ceci induise des efforts de flexion dans les portiques, le FRA-2 808 041 précité propose que la base des chapes soit en outre articulée par rapport au bord supérieur des dispositifs de coffrage au moyen d'un second axe d'articulation perpendiculaire aux faces coffrantes. En effet, ceci permet aux portiques, lors du soulèvement, de s'incliner l'un vers l'autre dans le prolongement des deux élingues. Un inconvénient de cette solution connue réside toutefois dans la complexité de réalisation de ces articulations supplémentaires, et donc dans un coût élevé des portiques. L'invention a pour but de fournir une solution plus simple et moins coûteuse à réaliser, et néanmoins très fiable, pour permettre l'inclinaison des portiques l'un vers l'autre lors du soulèvement des deux dispositifs de coffrage. A cet effet, l'invention a pour objet un dispositif de soulèvement du type précité, caractérisé en ce que lesdits moyens de liaison comprennent un ressort à lame(s) comportant au moins une lame de ressort adaptée pour fléchir vers l'autre desdits points. Le dispositif de soulèvement suivant l'invention peut comporter une ou plusieurs des caractéristiques suivantes : - la ou chaque lame est, au repos, contenue dans un plan sensiblement vertical perpendiculaire audit plan vertical ; - le ressort à lame(s) comprend plusieurs lames de ressort accolées les unes aux autres ; - l'extrémité inférieure de chaque organe de soulèvement est reliée au ressort à lame(s) associé par l'intermédiaire d'une articulation d'axe horizontal parallèle audit plan vertical défini par lesdits points ; - chaque organe rigide de soulèvement appartient à un portique de soulèvement de deux charges juxtaposées ; - chaque portique comprend un double parallélogramme articulé dont font partie les deux organes de soulèvement correspondants, et est muni d'un organe de suspension coulissant agencé de manière qu'une traction vers le haut exercée sur cet organe de suspension provoque l'écartement des deux organes de soulèvement ; - chaque parallélogramme articulé est relié au ressort à lame(s) associé par une chape de fixation, de sorte qu'une traction exercée vers le haut sur l'organe de suspension provoque un écartement des deux chapes parallèlement à elles-mêmes ; et - chaque ressort à lame(s) est fixé à chacune de ses extrémités par un ensemble de boulons. In order to prevent this from inducing bending forces in the gantries, the above-mentioned FRA-2 808 041 proposes that the base of the yokes be further articulated with respect to the upper edge of the formwork devices by means of a second axis of perpendicular articulation. to the formwork faces. Indeed, this allows the portals, when lifting, to bow to each other in the extension of the two slings. A disadvantage of this known solution lies however in the complexity of realization of these additional joints, and therefore in a high cost of gantries. The invention aims to provide a simpler and less expensive solution to achieve, and nevertheless very reliable, to allow the inclination of the gantries towards each other during the lifting of the two formwork devices. For this purpose, the invention relates to a lifting device of the aforementioned type, characterized in that said connecting means comprise a leaf spring (s) having at least one leaf spring adapted to bend towards the other of said points . The lifting device according to the invention may comprise one or more of the following characteristics: the or each blade is, at rest, contained in a substantially vertical plane perpendicular to said vertical plane; - The leaf spring (s) comprises a plurality of spring blades contiguous to each other; the lower end of each lifting member is connected to the associated leaf spring (s) via an articulation of horizontal axis parallel to said vertical plane defined by said points; each rigid lifting member belongs to a gantry for lifting two juxtaposed loads; each gantry comprises a double articulated parallelogram, of which the two corresponding lifting members form part, and is provided with a sliding suspension member arranged so that an upward traction exerted on this suspension member causes the spacing of the two uprising organs; - Each articulated parallelogram is connected to the leaf spring (s) associated by a fixing yoke, so that a traction exerted upwardly on the suspension member causes a spacing of the two yokes parallel to themselves; and - each leaf spring (s) is fixed at each of its ends by a set of bolts.
L'invention a également pour objet un ensemble de deux dispositifs de coffrage à faces coffrantes planes parallèles, caractérisé en ce que les bords supérieurs des dispositifs de coffrage sont reliés par deux dispositifs de soulèvement tels que définis ci-dessus. Un exemple de réalisation de l'invention va maintenant être décrit en regard des dessins annexés, sur lesquels : - la Figure 1 représente, en vue de côté, un ensemble de deux dispositifs de coffrage conforme à l'invention, posé sur le sol ; - la Figure 2 représente le même ensemble en vue de face ; - la Figure 3 représente à plus grande échelle le détail III de la Figure 2 ; - les Figures 4 à 6 sont des vues analogues respectivement aux Figures 1 à 3, alors que l'ensemble des deux dispositifs de coffrage est soulevé. Les Figures 1 et 2 représentent un ensemble constitué de deux dispositifs de coffrage 1A et 1B, de deux portiques 2.1 et 2.2 de soulèvement de ces dispositifs de coffrage, de deux élingues 3.1 et 3.2, et d'une chaîne de soulèvement 4 reliée à la flèche 5 d'une grue. Dans la description qui suit, les références numériques suivies de la lettre A ou B se rapportent au dispositis de coffrage 1A ou 1B respectivement, les références numériques suivies de .1 ou .2 se rapportent au côté gauche ou droit, en considérant les Figures 2 et 5, de chaque dispositif de coffrage, et les références numériques sans suffixe sont génériques par rapport à ces situations. Chaque dispositif de coffrage 1 a une forme générale plane et rectangulaire et présente une face avant coffrante lisse 6 tournée vers l'autre banche, ainsi qu'une face arrière munie de raidisseurs 7. Dans l'exemple représenté, chaque dispositif de coffrage est constitué de deux banches 8 et 9, juxtaposées et assemblées l'une à l'autre. En pratique, chaque dispositif de coffrage est associé à divers accessoires tels que des étais arrières de support, des passerelles de circulation des ouvriers, etc. Ces accessoires n'ont pas été représentés dans un but de clarté des dessins. Chaque portique 2 comprend deux ferrures verticales de soulèvement 10.1, 10.2 fixées rigidement, de façon amovible, sur le bord supérieur de chaque dispositif de coffrage, en deux points espacés l'un de l'autre. Les ferrures 10 font saillie vers le haut sur le bord supérieur des dispositifs de coffrage. Chaque ferrure forme une chape à section en U dont l'ouverture est tournée vers l'autre ferrure 10. Le rôle de ces chapes apparaîtra plus loin Chaque portique 2 comprend en outre un compas 12 dont tous les axes d'articulation sont horizontaux et parallèles aux faces coffrantes 6. Ce compas comprend lui-même une tête 13 sur laquelle sont articulées les extrémités supérieures de deux paires de bielles parallèles 14, 15 et 16, 17. Les extrémités inférieures de ces bielles sont articulées sur deux chapes respectives 18, 19 à section en U, les ouvertures des U se faisant face. Le compas 12 comprend aussi un dispositif 20 de suspension et d'écartement. Ce dispositif comprend une tige verticale de suspension 21 qui traverse en coulissant la tête 13 et est reliée à l'élingue 3 correspondante, ainsi que deux bielles d'écartement 22. Une extrémité de chaque bielle 22 est articulée à l'extrémité inférieure de la tige 21, et son autre extrémité est articulée en un point intermédiaire de la bielle inférieure 15, 17 respective de chacune des paires de bielles 14, 15 et 16, 17. The invention also relates to a set of two shuttering devices with parallel flat formwork faces, characterized in that the upper edges of the shuttering devices are connected by two lifting devices as defined above. An exemplary embodiment of the invention will now be described with reference to the accompanying drawings, in which: - Figure 1 shows, in side view, a set of two formwork devices according to the invention, placed on the floor; - Figure 2 shows the same set in front view; - Figure 3 shows on a larger scale detail III of Figure 2; - Figures 4 to 6 are views similar to Figures 1 to 3, respectively, while all two formwork devices is raised. Figures 1 and 2 show an assembly consisting of two formwork devices 1A and 1B, two gantries 2.1 and 2.2 for lifting these formwork devices, two slings 3.1 and 3.2, and a lifting chain 4 connected to the arrow 5 of a crane. In the description which follows, the numerical references followed by the letter A or B refer to the formwork devices 1A or 1B respectively, the numerical references followed by .1 or .2 relate to the left or right side, considering FIGS. and 5, of each formwork device, and the numerical references without suffix are generic with respect to these situations. Each formwork device 1 has a generally flat and rectangular shape and has a smooth formwork front face 6 facing the other side, and a rear face provided with stiffeners 7. In the example shown, each formwork device is constituted two banches 8 and 9, juxtaposed and assembled to one another. In practice, each formwork device is associated with various accessories such as rear support struts, worker circulation bridges, etc. These accessories have not been shown for the sake of clarity of the drawings. Each gantry 2 comprises two upright lifting brackets 10.1, 10.2 rigidly fixed, removably, on the upper edge of each formwork device, at two points spaced apart from each other. The fittings 10 project upward on the upper edge of the formwork devices. Each fitting forms a yoke with a U-section whose opening is turned towards the other fitting 10. The role of these yokes will appear later. Each gantry 2 further comprises a compass 12, all of whose hinge pins are horizontal and parallel. 6. This compass comprises itself a head 13 on which are articulated the upper ends of two pairs of parallel rods 14, 15 and 16, 17. The lower ends of these rods are articulated on two respective clevises 18, 19 U-section, the openings of the U facing each other. The compass 12 also comprises a device 20 for suspension and spacing. This device comprises a vertical suspension rod 21 which slidably traverses the head 13 and is connected to the corresponding sling 3, and two spacing rods 22. One end of each rod 22 is articulated to the lower end of the rod 21, and its other end is articulated at an intermediate point of the lower connecting rod 15, 17 respectively of each pair of rods 14, 15 and 16, 17.
Les bielles 15, 17 et 22 forment un losange déformable, tandis que chaque paire de bielles 14, 15 et 16, 17 forme avec la tête 13 et la chape 18, 19 associée un parallélogramme déformable. L'extrémité inférieure de chaque chape 18, 19 est reliée à l'extrémité supérieure de la ferrure 10 associée par un ressort à lames 24. Ce ressort est constitué par plusieurs lames d'acier à ressort 25 accolées les unes aux autres. Chaque lame est, au repos, contenue dans un plan vertical perpendiculaire aux faces coffrantes 6. Chaque ressort 24 est rigidement fixé à la ferrure 10 par un étau à quatre boulons 26 (Figures 3 et 6, tandis que son extrémité supérieure est disposée dans la chape 18, 19 associée et rigidement fixée à celle-ci par deux boulons 27. Au repos (Figures 1 à 3), les dispositifs de coffrage 1A et 1B sont posées sur le sol 28, parallèlement l'un à l'autre et avec leurs faces coffrantes 6 espacées de la distance d égale à l'épaisseur d'un voile de béton 29 à couler. Les deux compas 12 sont en position fermée, avec les bielles 14 à 17 faiblement inclinées sur la verticale et les bielles de chaque paire en contact mutuel, la tige 21 en position basse et les ressorts 24 au repos. Lorsque le voile 29 est prêt à être décoffré, les deux élingues 3 sont accrochées à l'extrémité supérieure des deux tiges 21, et la chaîne 4 est relevée par la grue. Dès que les deux dispositifs de coffrage 1 quittent le sol, les bielles 22 provoquent l'écartement des paires de bielles 14 à 17. Du fait des deux parallélogrammes formés par ces paires de bielles, les deux chapes 18 et 19 s'écartent parallèlement à elles-mêmes en se soulevant. Ceci provoque finalement l'écartement des deux dispositifs de coffrage l'un de l'autre dès le début de leur soulèvement, tout en conservant la stabilité de ceux-ci. Simultanément (Figures 1 et 5), la tension des deux élingues 3.1 et 3.2 et la flexibilité des ressorts 24 ont pour conséquence que les deux portiques 2 s'inclinent l'un vers l'autre dans le prolongement des élingues. Ainsi, aucune contrainte de flexion substantielle ne s'exerce sur les portiques. Les ressorts 24 et leur fixation par un simple ensemble de boulons permet d'obtenir ce résultat de manière particulièrement simple, économique à réaliser et fiable, avec un retour automatique de ces ressorts en position de repos.25 The rods 15, 17 and 22 form a deformable rhombus, while each pair of rods 14, 15 and 16, 17 form with the head 13 and the yoke 18, 19 associated with a deformable parallelogram. The lower end of each yoke 18, 19 is connected to the upper end of the associated fitting 10 by a leaf spring 24. This spring is constituted by a plurality of spring steel blades 25 contiguous to each other. Each blade is, at rest, contained in a vertical plane perpendicular to the formwork faces 6. Each spring 24 is rigidly fixed to the fitting 10 by a four bolt vise 26 (FIGS. 3 and 6, while its upper end is disposed in the clevis 18, 19 associated and rigidly fixed thereto by two bolts 27. At rest (Figures 1 to 3), the formwork devices 1A and 1B are placed on the floor 28, parallel to each other and with their form faces 6 spaced apart by the distance d equal to the thickness of a concrete web 29. The two compasses 12 are in the closed position, with the rods 14 to 17 slightly inclined to the vertical and the connecting rods of each pair in contact with each other, the rod 21 in the low position and the springs 24 at rest When the sail 29 is ready to be removed, the two slings 3 are hooked to the upper end of the two rods 21, and the chain 4 is raised by the crane. Formwork devices 1 leave the ground, the rods 22 cause the spacing of the pairs of rods 14 to 17. Due to the two parallelograms formed by these pairs of rods, the two yokes 18 and 19 deviate parallel to themselves in getting up. This finally causes the spacing of the two formwork devices from each other from the beginning of their uprising, while maintaining the stability thereof. Simultaneously (Figures 1 and 5), the tension of the two slings 3.1 and 3.2 and the flexibility of the springs 24 have the consequence that the two gantries 2 incline towards each other in the extension of the slings. Thus, no substantial bending stress is exerted on the gantries. The springs 24 and their attachment by a simple set of bolts makes it possible to obtain this result in a particularly simple manner, which is economical to produce and reliable, with an automatic return of these springs in the rest position.
