Abstract

The shuttering system consists of two panels (B1,B2), connected at their upper ends by an articulated structure (10) which is able to stabilise the panels in an open position giving access between them for pre-casting work and a position in which they are close together for casting. One panel (B2) has main rollers (40) to enable it to be moved between the two positions. The upper articulated structure (10) inclines the upper end of the panel (B2) outwards before and during its rolling movement to provide stability and allows the panel to be brought into the upright position for casting. Panel (B2) is also equipped with thrust rollers (50) which are located further away from the panel face than the main rollers, and the panel's centre of gravity passes between the rollers when the panel is inclined.

Description

La présente invention concerne la construction des structures de bâtiments et d'ouvrages de travaux publics, et plus particulièrement un dispositif de coffrage pour la réalisation de murs verticaux, également dénommés voiles, par coulage de béton entre deux panneaux de coffrage, également dénommés banches.The present invention relates to the construction of building structures and public works, and more particularly a formwork device for the realization of vertical walls, also called sails, by pouring concrete between two formwork panels, also called formwork.

Les panneaux de coffrage sont reliés supérieurement par un dispositif mécanique du commerce dénommé "compas" pour d'une part le transport, d'un seul coup de grue, d'un couple de panneaux d'un point de travail à un autre, et d'autre part pour assurer la stabilité des panneaux. Lorsqu'un couple de panneaux est déposé sur une dalle d'appui en un nouvel emplacement de travail, un premier panneau est posé prêt au coffrage tandis que le deuxième est maintenu provisoirement écarté de sa position de coffrage, afin de permettre une intervention entre les panneaux, par exemple pour effectuer des opérations de nettoyage, de graissage, de mise en place d'armatures ou d'incorporations diverses. Lorsque ces opérations préalables au coffrage sont terminées, le deuxième panneau est rapproché du premier, soit au moyen de barres à mine et par à-coups successifs, soit au moyen de la grue. Dans le premier cas, l'action des barres à mine détériore le coffrage et marque la dalle d'appui si celle-ci est fraîchement coulée, et dans le deuxième cas l'intervention de la grue est pénalisante pour la productivité et l'organisation générale du chantier.The formwork panels are connected superiorly by a commercial mechanical device called "compass" for on the one hand the transport, with a single crane blow, of a pair of panels from one work point to another, and on the other hand to ensure the stability of the panels. When a pair of panels is placed on a support slab in a new work location, a first panel is placed ready for formwork while the second is temporarily kept away from its formwork position, to allow intervention between the panels, for example for carrying out cleaning, lubrication, placement of reinforcements or various incorporations. When these operations prior to formwork are completed, the second panel is brought closer to the first, either by means of crow bars and in successive blows, or by means of the crane. In the first case, the action of the crow bars deteriorates the formwork and marks the support slab if it is freshly poured, and in the second case the intervention of the crane is penalizing for productivity and organization general site.

On a proposé dans la publication FR-A-2 459 860 un dispositif de coffrage comprenant deux panneaux de coffrage reliés supérieurement par au moins une structure articulée apte à stabiliser les panneaux dans une position écartée permettant l'accès entre les panneaux pour des opérations préalables au coulage et dans une position rapprochée pour le coulage de béton entre les panneaux, l'un des panneaux étant muni de roulettes principales permettant son déplacement par roulage entre lesdites positions.FR-A-2 459 860 has proposed a formwork device comprising two formwork panels connected above by at least one articulated structure capable of stabilizing the panels in a spaced-apart position allowing access between the panels for prior operations. during pouring and in a close position for pouring concrete between the panels, one of the panels being provided with main rollers allowing its movement by rolling between said positions.

La présente invention a pour objet de proposer un dispositif de coffrage perfectionné permettant d'effectuer le transport du deuxième panneau vers sa position de coffrage sans endommagement de celui-ci ou de la dalle d'appui et sans intervention de la grue, et de stabilité améliorée pendant le transport.The present invention aims to provide an improved formwork device for carrying out the transport of the second panel to its formwork position without damaging it or the support slab and without intervention of the crane, and stability improved during transport.

L'invention y parvient par le fait que la structure est conçue pour permettre une inclinaison de ce panneau vers l'arrière avant et pendant le roulage de façon à assurer la stabilité du dispositif de coffrage, et pour permettre le redressement de ce panneau lorsqu'il est arrivé en position rapprochée.The invention achieves this by the fact that the structure is designed to allow this panel to tilt backwards before and during rolling so as to ensure the stability of the formwork device, and to allow the straightening of this panel when he arrived in the close position.

L'écartement et le rapprochement des panneaux peuvent ainsi se faire sans détérioration de la dalle d'appui ou des panneaux, et avec une grande sécurité de par l'inclinaison du panneau équipé des roulettes principales, avant et pendant le roulage.The spacing and the bringing together of the panels can thus be done without deterioration of the support slab or of the panels, and with great safety due to the inclination of the panel equipped with the main rollers, before and during taxiing.

Dans une réalisation de l'invention, la structure articulée utilisée est un compas dont les articulations présentent, en position rapprochée des panneaux, un jeu suffisant permettant le redressement du panneau équipé des roulettes principales. Avantageusement, le panneau équipé des roulettes principales présente en outre des roulettes d'appui plus éloignées que les roulettes principales de son bord inférieur, la verticale du centre de gravité de ce panneau lorsqu'il est en position inclinée passant entre les axes des roulettes principales et des roulettes d'appui. L'axe de chaque roulette d'appui s'étend de préférence entre des flasques articulés sur un support solidaire du panneau, ces flasques étant basculables entre une première position d'appui sur le sol tendant à maintenir le panneau en position redressée et une deuxième position d'appui sur le sol correspondant à la position inclinée du panneau. Avantageusement, la hauteur de l'axe des roulettes principales, mesurée par rapport au bord inférieur du panneau qu'elles équipent, est réglable, ce qui permet de compenser des irrégularités de surface que pourrait présenter la dalle d'appui ou de franchir des obstacles.In one embodiment of the invention, the articulated structure used is a compass, the articulations of which, in the position close to the panels, have sufficient play allowing the straightening of the panel equipped with the main rollers. Advantageously, the panel fitted with the main rollers also has support rollers more distant than the main rollers from its lower edge, the vertical of the center of gravity of this panel when in the inclined position passing between the axes of the main rollers. and support casters. The axis of each support wheel preferably extends between flanges articulated on a support integral with the panel, these flanges being tiltable between a first support position on the ground tending to keep the panel in the upright position and a second support position on the ground corresponding to the inclined position of the panel. Advantageously, the height of the axis of the main rollers, measured relative to the lower edge of the panel which they equip, is adjustable, which makes it possible to compensate for surface irregularities which the support slab could have or to overcome obstacles. .

La présente invention a ainsi pour objet un procédé pour réaliser un mur en béton comprenant les étapes consistant à :

  • a) déposer à l'aide d'un dispositif de levage un dispositif de coffrage conforme à l'invention, l'un des panneaux étant positionné de manière à définir une face principale du mur à construire, les deux panneaux étant initialement dans une position écartée autorisant l'accès entre eux pour effectuer des opérations préalables au coffrage, telles que le nettoyage, le graissage, la mise en place d'armatures, ou d'incorporations diverses, l'autre panneau étant équipé de roulettes, la stabilité du dispositif de coffrage étant assurée par la ou les structures articulées,
  • b) rapprocher par roulage le panneau équipé de roulettes pour l'amener dans une position où il définit l'autre face principale du mur à construire,
  • c) couler du béton entre les panneaux,
  • d) procéder au décoffrage,

caractérisé en ce que le panneau est incliné avant et pendant le roulage et redressé au terme du roulage.The present invention thus relates to a method for producing a concrete wall comprising the steps consisting in:
  • a) deposit using a lifting device a formwork device according to the invention, one of the panels being positioned so as to define a main face of the wall to be constructed, the two panels being initially in a position separated allowing access between them to perform operations prior to the formwork, such as cleaning, lubrication, the installation of reinforcements, or various incorporations, the other panel being equipped with rollers, the stability of the device formwork being provided by the articulated structure or structures,
  • b) bringing the panel fitted with rollers together to bring it into a position where it defines the other main face of the wall to be constructed,
  • c) pouring concrete between the panels,
  • d) formwork removal,

characterized in that the panel is inclined before and during driving and straightened at the end of driving.

Le dispositif de coffrage représenté sur la figure 1 comprend deux panneaux de coffrage B1 et B2 en regard l'un de l'autre, reliés supérieurement par au moins une structure articulée. Dans l'exemple décrit, les panneaux B1 et B2 sont reliés par deux compas 10 respectivement situés à proximité des bords verticaux opposés des panneaux, l'un seulement des deux compas 10 étant visible sur la figure 1. Chaque compas 10 comprend de façon connue en soi deux montants 11 et 12 respectivement fixés sur les panneaux B1 et B2 et deux couples de bielles parallèles 13, 14, articulées à une extrémité sur les montants 11 et 12 et à l'autre extrémité sur une pièce commune 15, de manière à maintenir les montants 11 et 12 généralement parallèles, quel que soit l'écartement des panneaux B1 et B2. Toutefois, les articulations des bielles présentent un jeu qui autorise un débattement angulaire du panneau B2, ce débattement angulaire augmentant lorsque l'écartement entre les panneaux diminue. En position rapprochée des panneaux, comme représenté sur la figure 2, le débattement angulaire β atteint quelques degrés de part et d'autre de la position représentée en trait plein, ce qui est suffisant pour permettre le redressement du panneau B2 depuis une position inclinée, comme cela sera précisé dans la suite.The formwork device shown in Figure 1 comprises two formwork panels B1 and B2 facing each other, connected superiorly by at least one articulated structure. In the example described, the panels B1 and B2 are connected by two compasses 10 respectively located near the opposite vertical edges of the panels, only one of the two compasses 10 being visible in FIG. 1. Each compass 10 comprises in known manner per se two uprights 11 and 12 respectively fixed on the panels B1 and B2 and two pairs of parallel connecting rods 13, 14, articulated at one end on the uprights 11 and 12 and at the other end on a common part 15, so as to maintain the uprights 11 and 12 generally parallel, regardless of the spacing of the panels B1 and B2. However, the articulations of the connecting rods have a clearance which allows an angular movement of the panel B2, this angular travel increasing when the spacing between the panels decreases. In the close position of the panels, as shown in FIG. 2, the angular movement β reaches a few degrees on either side of the position shown in solid lines, which is sufficient to allow the straightening of the panel B2 from an inclined position, as will be explained below.

Les panneaux B1 et B2 sont équipés chacun de façon connue en soi sur leur face opposée à la face coffrante d'une passerelle 16 et de structures d'appui arrière respectives 20 et 30. On n'aperçoit sur la figure 1 qu'une seule structure d'appui arrière 20 et une seule structure d'appui arrière 30 équipant respectivement les panneaux B1 et B2. Les structures 20 et 30 comportent des étais de longueur réglable référencés respectivement 21 et 31.The panels B1 and B2 are each equipped in a manner known per se on their face opposite to the formwork face of a gangway 16 and of respective rear support structures 20 and 30. We can see in FIG. 1 only one rear support structure 20 and a single rear support structure 30 fitted respectively to panels B1 and B2. The structures 20 and 30 comprise stays of adjustable length referenced respectively 21 and 31.

Le dispositif de coffrage est représenté sur la figure 1 avec les panneaux B1 et B2 dans une position écartée permettant d'effectuer entre les panneaux des opérations préalables au coulage de béton. Le panneau B1 repose prêt au coffrage, sa face coffrante étant verticale, sur une dalle d'appui D par son arête inférieure A1 et par des patins 22 montés à l'extrémité inférieure des étais 21. Le panneau B2 est quant à lui incliné vers l'arrière, formant avec le panneau B1 un angle ouvert vers le haut. Les montants 11 sont fixés sur le panneau B1 de manière à s'étendre verticalement lorsque ce dernier est posé prêt au coffrage sur la dalle d'appui D et les montants 12 sont fixés sur le panneau B2 de manière à s'étendre à peu près verticalement lorsque le panneau B2 est incliné vers l'arrière, comme représenté sur la figure 1. Lorsque le panneau B2 est rapproché du panneau B1, les compas 10 se déforment en maintenant les deux montants 11 et 12 généralement parallèles, donc en maintenant le panneau B2 incliné vers l'arrière, ce qui garantit une grande stabilité au dispositif de coffrage avant et durant le rapprochement des panneaux.The formwork device is shown in FIG. 1 with the panels B1 and B2 in a separated position allowing operations to be carried out between the panels prior to the pouring of concrete. The panel B1 rests ready for formwork, its formwork face being vertical, on a support slab D by its lower edge A1 and by pads 22 mounted at the lower end of the props 21. The panel B2 is inclined towards the rear, forming with the panel B1 an open angle upwards. The uprights 11 are fixed on the panel B1 so as to extend vertically when the latter is placed ready for formwork on the support slab D and the uprights 12 are fixed on the panel B2 so as to extend approximately vertically when the panel B2 is tilted backwards, as shown in FIG. 1. When the panel B2 is brought closer to the panel B1, the compasses 10 are deformed while keeping the two uprights 11 and 12 generally parallel, therefore maintaining the panel B2 inclined backwards, which guarantees great stability to the formwork device before and during the bringing together of the panels.

Ce rapprochement s'effectue par roulage grâce à des roulettes principales 40 équipant le panneau B2 et à des roulettes d'appui 50 montées à l'extrémité inférieure des étais 31, le centre de gravité du panneau B2, lorsqu'il est incliné vers l'arrière, passant entre les axes de rotation, parallèles, des roulettes principales 40 et des roulettes d'appui 50.This approximation is effected by rolling thanks to the main rollers 40 fitted to the panel B2 and to the support rollers 50 mounted at the lower end of the stays 31, the center of gravity of the panel B2, when it is inclined towards the rear, passing between the parallel axes of rotation, main rollers 40 and support rollers 50.

Les roulettes principales 40 sont supportées chacune par un axe 41 monté en rotation, par des moyens de support solidaires du panneau B2, le plus proche possible de l'arête inférieure A2 de ce dernier. L'axe 41 présente une extrémité axiale conformée pour venir en prise avec une clé à cliquet, pour l'entraînement en rotation de la roulette principale 40 associée. Dans l'exemple décrit, les moyens de support de l'axe 41 sont fixes par rapport au panneau B2. En variante, on peut monter l'axe 41 sur des moyens de support autorisant un réglage de sa hauteur, mesurée par rapport à l'arête inférieure A2, ce qui permet de compenser des irrégularités de surface de la dalle d'appui D et d'éviter des obstacles lors du roulage. L'axe 41 est positionné par rapport à l'arête A2 de manière à ce qu'en position inclinée du panneau B2, l'arête inférieure A2 ne repose pas sur la dalle d'appui D.The main rollers 40 are each supported by an axis 41 mounted in rotation, by support means integral with the panel B2, as close as possible to the lower edge A2 of the latter. Axis 41 presents an axial end shaped to engage with a ratchet, for driving the associated main wheel 40 in rotation. In the example described, the support means of the axis 41 are fixed relative to the panel B2. As a variant, the axis 41 can be mounted on support means allowing its height to be adjusted, measured relative to the lower edge A2, which makes it possible to compensate for surface irregularities of the support slab D and d '' avoid obstacles when driving. The axis 41 is positioned relative to the edge A2 so that in the inclined position of the panel B2, the lower edge A2 does not rest on the support slab D.

Comme représenté plus particulièrement sur les figures 3 et 4, l'étai 31 est articulé à son extrémité supérieure en 32 sur le panneau B2. Chaque structure d'appui arrière 30 comporte un bras 33 s'articulant à une extrémité en 34 sur l'étai 31 et présentant à son autre extrémité 35 un crochet permettant l'accrochage sur le panneau B2, pour maintenir l'étai 31 dans une position de soutien du panneau B2.As shown more particularly in Figures 3 and 4, the forestay 31 is articulated at its upper end at 32 on the panel B2. Each rear support structure 30 comprises an arm 33 articulated at one end at 34 on the forestay 31 and having at its other end 35 a hook allowing the attachment to the panel B2, to hold the forestay 31 in a support position of panel B2.

On a détaillé sur les figures 5 et 6 le montage de la roulette d'appui 50 à l'extrémité inférieure de l'étai 31. Conformément à une caractéristique avantageuse de l'invention, et comme représenté plus particulièrement sur la figure 6, l'axe 55 de chaque roulette d'appui 50 équipant un étai 31 s'étend entre deux flasques 52 montés à basculement sur un support 53 prolongeant inférieurement l'étai 31. Un tube 54, non représenté sur la figure 6 pour des raisons de clarté du dessin, est rapporté extérieurement sur l'un des flasques 52 pour recevoir un levier de basculement des flasques 52. L'axe 55 est soudé à ses extrémités aux flasques 52. Ces derniers s'articulent autour d'un axe 56 traversant le support 53 en s'étendant parallèlement à l'axe 55. Le support 53 est soudé sur une plaque plane 58, elle-même boulonnée sur une plaque plane 57 soudée à l'extrémité inférieure de l'étai 31 et s'étendant généralement perpendiculairement à l'axe longitudinal de ce dernier.The mounting of the support roller 50 at the lower end of the forestay 31 has been detailed in FIGS. 5 and 6. In accordance with an advantageous characteristic of the invention, and as shown more particularly in FIG. 6, l 'axis 55 of each support wheel 50 fitted to a forestay 31 extends between two flanges 52 pivotally mounted on a support 53 extending below the forestay 31. A tube 54, not shown in FIG. 6 for reasons of clarity of the drawing, is attached externally to one of the flanges 52 to receive a lever for tilting the flanges 52. The axis 55 is welded at its ends to the flanges 52. The latter are articulated around an axis 56 passing through the support 53 extending parallel to the axis 55. The support 53 is welded to a flat plate 58, itself bolted to a flat plate 57 welded to the lower end of the forestay 31 and extending generally perpendicular to the longitu axis dinal of the latter.

Les flasques 52 présentent sur leur contour deux bords 52a et 52b conformés pour venir en butée, lors du basculement des flasques 52 autour de l'axe 56, contre la plaque 58 afin de définir deux positions différentes pour la roulette d'appui 50, correspondant aux figures 3 et 4, et représentées en trait plein et en traits discontinus sur la figure 5. Plus précisément, dans la position de la figure 3, les flasques 52 viennent en butée contre la plaque 58 par leurs bords 52a et, dans la position de la figure 3, après basculement de 90° environ de ces derniers dans le sens horaire sur la figure 2, par leurs bords 52b, pour redresser le panneau B2.The flanges 52 have on their contour two edges 52a and 52b shaped to come into abutment, during the tilting of the flanges 52 around the axis 56, against the plate 58 in order to define two different positions for the support roller 50, corresponding in Figures 3 and 4, and shown in solid lines and in broken lines in Figure 5. More specifically, in the position of Figure 3, the flanges 52 abut against the plate 58 by their edges 52a and, in the position of Figure 3, after tilting about 90 ° of the latter clockwise in Figure 2, by their edges 52b, to straighten the panel B2.

Chaque bras 33 comporte comme représenté sur la figure 6 deux branches articulées par des pattes 34 sur un axe 38. Cet axe 38 traverse l'étai 31 perpendiculairement à son axe longitudinal, et s'étend parallèlement aux axes 55 et 56. Les branches 33 divergent en éloignement de l'axe 38 avec un écartement donné par des entretoises 39 s'étendant parallèlement à cet axe.Each arm 33 comprises, as shown in FIG. 6, two branches articulated by lugs 34 on an axis 38. This axis 38 crosses the forestay 31 perpendicular to its longitudinal axis, and extends parallel to the axes 55 and 56. The branches 33 diverge away from the axis 38 with a spacing given by spacers 39 extending parallel to this axis.

La mise en oeuvre du dispositif de coffrage selon la présente invention va maintenant être décrite en référence aux figures 7A à 7H.The implementation of the formwork device according to the present invention will now be described with reference to Figures 7A to 7H.

Le dispositif de coffrage est déposé par tout moyen de levage approprié sur la dalle d'appui D, le panneau B1 étant posé directement dans sa position de coffrage représentée sur la figure 7A, dans laquelle il définit une face du mur à construire. De préférence, conformément à une caractéristique avantageuse de l'invention, le dispositif de coffrage est muni de crochets de levage L1 et L2 agencés sur les panneaux B1 et B2 de manière à ce que lorsque le dispositif de coffrage est déposé sur la dalle d'appui D, le panneau B1 touche le sol en premier.The formwork device is deposited by any suitable lifting means on the support slab D, the panel B1 being placed directly in its formwork position shown in FIG. 7A, in which it defines a face of the wall to be constructed. Preferably, in accordance with an advantageous characteristic of the invention, the formwork device is provided with lifting hooks L1 and L2 arranged on the panels B1 and B2 so that when the formwork device is placed on the slab of support D, panel B1 touches the ground first.

Le panneau B1 repose par son arête inférieure A1 et par les patins 22 des structures d'appui arrière 20 sur la dalle d'appui D, sa face coffrante étant verticale. Le panneau B2 repose sur la dalle d'appui par l'intermédiaire des roulettes principales 40 et des roulettes d'appui 50 en position de roulage, l'arête inférieure A2 étant décollée de la dalle d'appui D, d'une distance de 1,5 cm environ dans l'exemple décrit. Les flasques 52 sont dans leur position de roulage représentée sur la figure 3, c'est-à-dire avec les bords 52a venant en butée contre la plaque 58. Dans cette position écartée des panneaux B1 et B2 représentée sur la figure 7A, on procède de façon connue en soi au nettoyage des panneaux, à leur graissage, à la mise en place d'armatures R sur des fers en attente ou d'incorporations diverses.The panel B1 rests by its lower edge A1 and by the pads 22 of the rear support structures 20 on the support slab D, its formwork face being vertical. The panel B2 rests on the support slab via the main rollers 40 and the support rollers 50 in the rolling position, the lower edge A2 being detached from the support slab D, from a distance of 1.5 cm approximately in the example described. The flanges 52 are in their rolling position shown in FIG. 3, that is to say with the edges 52a abutting against the plate 58. In this position separated from the panels B1 and B2 shown in FIG. 7A, proceeds in a manner known per se to the cleaning of the panels, to their lubrication, to the installation of reinforcements R on waiting irons or of various incorporations.

Ensuite, comme représenté sur la figure 7B, le panneau B2 est rapproché du panneau B1, les compas 10 maintenant le panneau B2 incliné lors du roulage. Le déplacement du panneau B2 s'effectue de préférence au moyen d'une clé à cliquet venant en prise avec l'axe 41 d'une roulette principale 40.Then, as shown in FIG. 7B, the panel B2 is brought closer to the panel B1, the compasses 10 holding the panel B2 inclined during rolling. The displacement of the panel B2 is preferably carried out by means of a ratchet wrench engaging with the axis 41 of a main roller 40.

Au terme du roulage, comme représenté sur la figure 7C, le panneau B2 est redressé par basculement des flasques 52, au moyen d'un levier engagé dans le tube 54, jusqu'à butée des bords 52b de ces derniers contre la plaque 58. Ce redressement est possible grâce au jeu des articulations des bielles 13 et 14 des compas 10 en position rapprochée des panneaux. L'arête inférieure A2 du panneau B2 vient reposer sur le sol tandis que la roulette principale 40 décolle légèrement de la dalle d'appui D. Les deux panneaux sont avantageusement maintenus de façon connue en soi, pour le coulage de béton, par des tiges filetées F représentées sur la figure 7D, ces tiges permettant d'ajuster avec précision le parallélisme des faces coffrantes.At the end of rolling, as shown in FIG. 7C, the panel B2 is straightened by tilting the flanges 52, by means of a lever engaged in the tube 54, until the edges 52b of the latter abut against the plate 58. This straightening is possible thanks to the play of the articulations of the connecting rods 13 and 14 of the compasses 10 in the close position of the panels. The lower edge A2 of the panel B2 comes to rest on the ground while the main caster 40 takes off slightly from the support slab D. The two panels are advantageously held in a manner known per se, for pouring concrete, by threaded rods F shown in FIG. 7D, these rods making it possible to precisely adjust the parallelism of the shuttering faces.

Après la prise du béton, le dispositif de coffrage est démonté conformément à la figure 7E en inclinant légèrement les panneaux B1 et B2 vers l'arrière par le raccourcissement des étais 21 et 31 des structures d'appui arrière 20 et 30. Puis le panneau B2 est incliné par basculement des flasques 52 vers leur position de roulage représentée sur la figure 3, c'est-à-dire avec les bords 52a venant en butée contre la plaque 58.After the concrete has set, the formwork device is dismantled in accordance with FIG. 7E by slightly tilting the panels B1 and B2 backwards by shortening the stays 21 and 31 of the rear support structures 20 and 30. Then the panel B2 is inclined by tilting the flanges 52 towards their rolling position shown in FIG. 3, that is to say with the edges 52a abutting against the plate 58.

Le dispositif de coffrage est ensuite enlevé comme montré sur la figure 7F, à l'aide de câbles de levage C passant au travers d'un écarteur E, pour être déplacé vers une nouvelle position de travail. Les câbles C sont écartés d'une distance supérieure à la distance entre les crochets de levage L1 et L2 des panneaux B1 et B2, de sorte que lorsque le dispositif de coffrage est soulevé, les panneaux B1 et B2 tendent, sous l'effet de leur propre poids, à s'éloigner l'un de l'autre, comme représenté sur la figure 7G. De préférence, l'écarteur E est choisi de manière à ce que l'écartement des panneaux B1 et B2 durant leur transport soit inférieur à l'écartement maximal permis par les compas 10.The formwork device is then removed as shown in Figure 7F, using lifting cables C passing through a spacer E, to be moved to a new working position. The cables C are spaced a distance greater than the distance between the lifting hooks L1 and L2 of the panels B1 and B2, so that when the formwork device is raised, the panels B1 and B2 tend, under the effect of their own weight, to move away from each other, as shown in Figure 7G. Preferably, the spacer E is chosen so that the spacing of the panels B1 and B2 during their transport is less than the maximum spacing allowed by the compasses 10.

Le dispositif de coffrage peut être transporté avec les panneaux B1 et B2 dans une position proche de leur écartement maximum ou dans une position d'écartement intermédiaire entre la position d'écartement maximum et la position rapprochée. Le deuxième cas permet d'éviter des obstacles lors de la pose du dispositif de coffrage, l'écartement des panneaux étant ensuite corrigé, le cas échéant, par roulage du panneau B2.The formwork device can be transported with the panels B1 and B2 in a position close to their maximum spacing or in an intermediate spacing position between the maximum spacing position and the close position. The second case makes it possible to avoid obstacles during the installation of the formwork device, the spacing of the panels then being corrected, if necessary, by rolling the panel B2.
