Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne le domaine des banches de coffrage utilisées, en particulier, pour former des voiles en béton verticaux. On connaît de telles banches dans l'art antérieur, par exemple, par la demande de brevet FR 2941254 de la société SATECO . Pour rappel, une banche de coffrage comporte une structure de support sur laquelle est montée une paroi comprenant une face coffrante.The present invention relates to the field of formwork panels used, in particular, to form vertical concrete walls. Such forms are known in the prior art, for example, by the patent application FR 2941254 of the company SATECO . As a reminder, a formwork form comprises a support structure on which is mounted a wall comprising a formwork face.

De manière traditionnelle, pour former un voile en béton de longueur importante, il est courant de relier latéralement côte à côte plusieurs banches entres elles. De manière connue, la liaison latérale entre deux banches est réalisée selon trois points à des hauteurs différentes : un point bas, un point médian et un point haut. A cet effet, chaque banche comporte latéralement des moyens de liaison bas, des moyens de liaison médian et des moyens de liaison haut pour coopérer avec des moyens de liaison complémentaires d'une autre banche. Ainsi, en fonction de la longueur du voile en béton à former, on détermine le nombre de banches à relier. Un ensemble de banches reliées est communément appelé « train de banches ».Traditionally, to form a concrete veil of significant length, it is common to laterally connect several formwork panels together. In known manner, the lateral connection between two formwork panels is made at three points at different heights: a low point, a midpoint and a high point. To this end, each form has laterally bottom connection means, middle connection means and top connection means to cooperate with complementary connection means of another form. Thus, depending on the length of the concrete veil to be formed, the number of formwork panels to be connected is determined. A set of connected formwork is commonly called a "formwork train".

Pour former un voile en béton plan, il est important de régler l'alignement des banches de manière à ce que leurs surfaces coffrantes soient dans un même plan. On connaît dans l'art antérieur des moyens de liaison se présentant sous la forme d'un système vis-écrou. De tels systèmes sont pénibles à mettre en œuvre étant donné que cela oblige les opérateurs à se baisser pour réaliser un serrage au niveau du point bas et à monter sur une échelle pour réaliser un serrage au niveau du point haut. Ces opérations sont fatigantes et/ou consommatrices de temps pour un opérateur, ce qui présente un inconvénient. En outre, les tensions de serrage ne sont pas uniformes dans un même train de banches étant donné que chaque opérateur peut appliquer une tension de serrage différente.To form a flat concrete wall, it is important to adjust the alignment of the formwork so that their formwork surfaces are in the same plane. Connection means are known in the prior art in the form of a screw-nut system. Such systems are difficult to implement since this forces operators to bend down to tighten at the low point and to climb a ladder to tighten at the high point. These operations are tiring and/or time-consuming for an operator, which has a drawback. In addition, the tightening tensions are not uniform in the same train of formwork since each operator can apply a different tightening tension.

Il a été proposé par la demande de brevet FR2808039 un dispositif de rapprochement et d'affleurement de banches dans lequel des broches de positionnement sont guidées en translation au niveau du point haut et du point bas. Dans cette demande de brevet, le rapprochement des banches au niveau du point médian entraîne, de manière synchronisée, une translation des broches de positionnement au niveau du point haut et du point bas. Ainsi, la pénibilité des opérateurs est limitée. Néanmoins, en l'absence de serrage comme dans l'art antérieur, un espace peut apparaître entre les deux banches au niveau du point haut et/ou du point bas du fait des efforts de bétonnage, ce qui peut entraîner un défaut d'étanchéité du coffrage. Aussi, en pratique, il demeure nécessaire que des opérateurs viennent manuellement assurer un serrage au niveau du point haut et du point bas, ce qui augmente la pénibilité. Enfin, en pratique, un serrage au point haut et au point bas est complexe à réaliser lorsque les banches ne sont pas parfaitement alignées.It was proposed by the patent application FR2808039 a device for approaching and flushing formwork in which positioning pins are guided in translation at the level of the high point and the low point. In this patent application, the bringing together of the formwork at the level of the midpoint causes, in a synchronized manner, a translation of the positioning pins at the level of the high point and the low point. Thus, the difficulty of the operators is limited. Nevertheless, in the absence of clamping as in the art front, a space may appear between the two formwork at the level of the high point and/or the low point due to concreting forces, which may lead to a lack of tightness of the formwork. Also, in practice, it remains necessary for operators to come manually to ensure tightening at the level of the high point and the low point, which increases the arduousness. Finally, in practice, tightening at the high point and at the low point is complex to achieve when the formwork panels are not perfectly aligned.

L'invention a donc pour but de remédier à ces inconvénients en proposant une banche apte à être reliée latéralement à une autre banche de manière simple, rapide et pratique afin de diminuer la pénibilité des opérateurs.The object of the invention is therefore to remedy these drawbacks by proposing a formwork able to be connected laterally to another formwork in a simple, rapid and practical manner in order to reduce the arduousness of the operators.

PRESENTATION DE L'INVENTIONPRESENTATION OF THE INVENTION

L'invention concerne une banche de coffrage comportant une face avant coffrante et au moins une première rive latérale comprenant au moins une ouverture de réception, s'étendant selon un axe d'ouverture horizontal, configurée pour permettre le passage d'une tige de liaison appartenant à un dispositif de liaison d'une autre banche de coffrage, la banche de coffrage comprenant un dispositif de serrage configuré pour exercer une traction sur la tige de liaison, le dispositif de serrage comprenant :

  • Au moins une tête, s'étendant en regard de l'ouverture de réception, comprenant une cavité ouverte configurée pour recevoir une extrémité de connexion de la tige de liaison,
  • Au moins un organe de verrouillage configuré pour bloquer en translation selon l'axe d'ouverture horizontal l'extrémité de connexion de la tige de liaison et la tête, et
  • Au moins un organe de déplacement de la tête en translation selon l'axe d'ouverture horizontal.
The invention relates to a formwork panel comprising a formwork front face and at least one first lateral edge comprising at least one receiving opening, extending along a horizontal opening axis, configured to allow the passage of a connecting rod belonging to a device for connecting another formwork formwork, the formwork formwork comprising a clamping device configured to exert traction on the connecting rod, the clamping device comprising:
  • At least one head, extending opposite the receiving opening, comprising an open cavity configured to receive a connection end of the connecting rod,
  • At least one locking member configured to lock in translation along the horizontal opening axis the connection end of the connecting rod and the head, and
  • At least one member for moving the head in translation along the horizontal opening axis.

Grâce à l'invention, le dispositif de serrage permet de réaliser un rapprochement par simple traction sur une tige de liaison qui est orientable. La présente invention prend le contre-pied d'une liaison traditionnelle au cours de laquelle un serrage est réalisé sur la tige de liaison. De manière préférée, l'organe de déplacement n'est pas orientable, ce qui permet de réaliser un effort de traction optimal de manière répétable. La durée de vie de l'organe de déplacement est avantageusement allongée. De plus, un dispositif de liaison selon l'art antérieur est compatible avec un dispositif de serrage selon l'invention, ce qui est avantageux. Enfin, en cas de dysfonctionnement du dispositif de serrage, une liaison des banches est toujours possible en réalisant un serrage comme dans l'art antérieur par serrage au niveau du dispositif de liaison.Thanks to the invention, the clamping device makes it possible to bring them together by simple traction on a connecting rod which is adjustable. The present invention takes the opposite of a traditional connection during which a tightening is carried out on the connecting rod. Preferably, the displacement member is not orientable, which makes it possible to achieve an optimal tractive effort in a repeatable manner. The service life of the displacement member is advantageously extended. In addition, a connection device according to the prior art is compatible with a clamping device according to the invention, which is advantageous. Finally, in the event of malfunction of the clamping device, a connection of the formwork is always possible by performing a tightening as in the prior art by tightening at the level of the connecting device.

De manière préférée, la tête comporte deux lumières traversantes. Cela permet avantageusement de réaliser un brochage rapide et robuste avec une extrémité de connexion. En outre, un brochage demeure possible même en cas d'inclinaison de la tige de liaison par rapport à l'axe d'ouverture horizontal.Preferably, the head comprises two through lights. This advantageously makes it possible to achieve fast and robust pinout with a connection end. In addition, broaching remains possible even in the event of inclination of the connecting rod with respect to the horizontal opening axis.

De manière préférée, l'organe de déplacement se présente sous la forme d'un actionneur hydraulique. Un tel actionneur permet de fournir une assistance à un opérateur et de diminuer sa pénibilité. Un actionneur hydraulique présente en outre l'avantage d'assurer une tension de serrage importante et précise.Preferably, the displacement member is in the form of a hydraulic actuator. Such an actuator makes it possible to provide assistance to an operator and to reduce his difficulty. A hydraulic actuator also has the advantage of ensuring a high and precise tightening tension.

De préférence, la première rive latérale comprenant au moins une ouverture de réception haute et une ouverture de réception basse, s'étendant respectivement selon des axes d'ouverture horizontaux, chaque ouverture de réception étant configurée pour permettre le passage d'une tige de liaison appartenant à un dispositif de liaison d'une autre banche de coffrage, la banche de coffrage comprend un dispositif de serrage haut et un dispositif de serrage bas, chaque dispositif de serrage étant configuré pour exercer une traction sur une tige de liaison.Preferably, the first lateral edge comprising at least one upper receiving opening and one lower receiving opening, extending respectively along horizontal opening axes, each receiving opening being configured to allow the passage of a connecting rod belonging to a connection device of another formwork formwork, the formwork formwork comprises a top clamping device and a bottom clamping device, each clamping device being configured to exert traction on a connecting rod.

De manière avantageuse, au moins deux dispositifs de serrage espacés verticalement permettent d'assurer une liaison entre les banches tout en conservant le parallélisme des faces avant coffrantes. Il va de soi qu'ils pourraient être plus nombreux. De manière préférée, chaque banche ne comporte que deux dispositifs de serrage. En effet, du fait de leurs performances améliorées, un serrage en deux points est suffisant, ce qui réduit le coût et la complexité d'une telle banche.Advantageously, at least two clamping devices spaced vertically make it possible to ensure a connection between the formwork while maintaining the parallelism of the formwork front faces. It goes without saying that there could be more of them. Preferably, each form has only two clamping devices. Indeed, because of their improved performance, a clamping at two points is sufficient, which reduces the cost and complexity of such a formwork.

De préférence, la banche comprend une unité de commande configurée pour coordonner les déplacements des organes de déplacement des deux dispositifs de serrage. Une unité de commande permet ainsi de rapprocher de manière optimale les deux rives en agissant, d'une part, sur le serrage bas et, d'autre part, sur le serrage haut afin de limiter les contraintes mécaniques pouvant conduire à une usure prématurée.Preferably, the formwork comprises a control unit configured to coordinate the movements of the displacement members of the two clamping devices. A control unit thus makes it possible to bring the two edges together in an optimal manner by acting, on the one hand, on the bottom clamping and, on the other hand, on the top clamping in order to limit the mechanical stresses which can lead to premature wear.

De préférence, la banche comprend une unité de commande configurée pour commander le déplacement de l'organe de déplacement, l'unité de commande étant adaptée pour être commandée par une visseuse électrique. Ainsi, un opérateur peut activer directement le déplacement avec une visseuse portative.Preferably, the formwork comprises a control unit configured to control the displacement of the displacement member, the control unit being adapted to be controlled by an electric screwdriver. Thus, an operator can directly activate the movement with a portable screwdriver.

De manière préférée, l'unité de commande comporte un organe de séquençage configurée pour commander tout d'abord le dispositif de serrage bas puis le dispositif de serrage haut. Un serrage au point bas permet de rapprocher les bases des banches et ainsi limiter les frottements et les contraintes mécaniques.Preferably, the control unit comprises a sequencing member configured to first control the bottom clamping device and then the top clamping device. A tightening at the low point makes it possible to bring the bases of the formwork closer together and thus limit friction and mechanical stress.

De manière préférée, l'unité de commande est configurée pour réaliser un serrage en position haute uniquement lorsque la tension de serrage au point bas est supérieure à un premier seuil de serrage déterminé. De manière avantageuse, on réalise tout d'abord un serrage partiel en position basse avant de débuter un serrage en position haute afin de réduire les contraintes mécaniques dans les rives.Preferably, the control unit is configured to carry out a clamping in the high position only when the clamping tension at the low point is greater than a first determined clamping threshold. Advantageously, a partial tightening is first carried out in the low position before starting a tightening in the high position in order to reduce the mechanical stresses in the edges.

De préférence, l'unité de commande est configurée pour réaliser ensuite un serrage en position haute et en position basse jusqu'à une tension de serrage finale prédéterminée. Ainsi, le serrage final est réalisé de manière simultanée pour gagner du temps lors de la liaison des banches.Preferably, the control unit is configured to then carry out a tightening in the high position and in the low position until a predetermined final tightening tension is reached. Thus, the final tightening is carried out simultaneously to save time when connecting the formwork.

De préférence, l'organe de verrouillage se présente sous la forme d'une broche.Preferably, the locking member is in the form of a pin.

Selon un aspect de l'invention, la banche comprend une deuxième rive latérale comprenant au moins une ouverture de passage, s'étendant coaxialement à l'axe d'ouverture horizontal de la première rive latérale, la banche comprenant un dispositif de liaison comprenant une tige de liaison configurée pour s'étendre dans l'ouverture de passage et être tractée par un dispositif de serrage d'une autre banche. Ainsi, plusieurs banches identiques peuvent être assemblées ensemble pour former un train de banches.According to one aspect of the invention, the formwork comprises a second lateral edge comprising at least one passage opening, extending coaxially to the horizontal opening axis of the first lateral edge, the formwork comprising a connecting device comprising a connecting rod configured to extend into the passage opening and to be pulled by a clamping device of another formwork. Thus, several identical formwork can be assembled together to form a train of formwork.

De manière préférée, le dispositif de liaison comprend un organe de centrage qui permet avantageusement d'orienter la tige de liaison et de rattraper les écarts de positionnement entre les banches lors de l'étape de rapprochement.Preferably, the connecting device comprises a centering member which advantageously makes it possible to orient the connecting rod and to compensate for the positioning differences between the formwork during the bringing together step.

L'invention concerne également un ensemble d'une première banche et d'une deuxième banche telles que présentées précédemment, dans lequel, le dispositif de liaison de la deuxième banche coopère avec le dispositif de serrage de la première banche, la tige de liaison traversant l'ouverture de passage de la deuxième banche et l'ouverture de réception de la première banche, l'organe de verrouillage du dispositif de serrage bloquant en translation selon l'axe d'ouverture horizontal l'extrémité de connexion de la tige de liaison et la tête du dispositif de serrage.The invention also relates to a set of a first formwork and a second formwork as presented above, in which the connecting device of the second formwork cooperates with the clamping device of the first formwork, the connecting rod passing through the opening for passage of the second form and the opening for receiving the first form, the locking member of the clamping device blocking in translation along the horizontal opening axis the connection end of the connecting rod and the head of the clamping device.

L'invention concerne également un procédé d'assemblage latéral d'une première banche à une deuxième banche d'un ensemble tel que présenté précédemment, le procédé comportant :

  • une étape de positionnement de la tige de liaison du dispositif de liaison de la deuxième banche dans la tête du dispositif de serrage de la première banche,
  • une étape de verrouillage, par l'organe de verrouillage du dispositif de serrage de la première banche, de l'extrémité de connexion de la tige de liaison à la tête, et
  • une étape de déplacement, par l'organe de déplacement du dispositif de serrage de la première banche, de la tête en translation selon l'axe d'ouverture horizontal de manière à rapprocher les deux banches.
The invention also relates to a method for lateral assembly of a first formwork to a second formwork of an assembly as presented above, the method comprising:
  • a step of positioning the connecting rod of the connecting device of the second form in the head of the clamping device of the first form,
  • a step of locking, by the locking member of the clamping device of the first formwork, of the connection end of the connecting rod to the head, and
  • a step of displacement, by the displacement member of the clamping device of the first formwork, of the head in translation along the horizontal axis of opening so as to bring the two formwork closer together.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence aux figures 1 et 2, il est représenté une banche 100 selon l'invention vue depuis l'avant (figure 1) et depuis l'arrière (figure 2). De manière classique, la banche 100 comporte une structure de support 101 sur laquelle est montée une paroi verticale définissant une face avant coffrante 102. Dans cet exemple, la face avant coffrante 102 se présente sous la forme d'une tôle en acier mais il va de soi qu'une tôle en inox ou une planche de bois pourraient également convenir. Dans cet exemple, la structure de support 101 comporte des raidisseurs verticaux fixés à la face avant coffrante 102. La banche 100 comporte en outre des rives périphériques s'étendant perpendiculairement à la paroi verticale. La banche 100 comporte en particulier deux rives latérales, une rive gauche G et une rive droite D, qui s'étendent verticalement et perpendiculairement à la face avant coffrante 102.With reference to figures 1 and 2 , there is shown a formwork 100 according to the invention seen from the front ( figure 1 ) and from behind ( picture 2 ). Conventionally, the formwork 100 comprises a support structure 101 on which is mounted a vertical wall defining a formwork front face 102. In this example, the formwork front face 102 is in the form of a steel sheet but it will of course that a stainless steel sheet or a wooden board could also be suitable. In this example, the support structure 101 comprises vertical stiffeners fixed to the front formwork face 102. The formwork 100 also comprises peripheral edges extending perpendicularly to the vertical wall. Formwork 100 has in particular two side edges, a left side G and a right side D, which extend vertically and perpendicular to the front formwork face 102.

Par la suite, la banche 100 est présentée dans un repère orthogonal (X, Y, Z) dans lequel l'axe X s'étend horizontalement et parallèlement à la paroi verticale de la droite vers la gauche, l'axe Y s'étend orthogonalement à la paroi verticale de l'arrière vers l'avant et l'axe Z s'étend verticalement et parallèlement à la paroi verticale du bas vers le haut.Subsequently, the formwork 100 is presented in an orthogonal frame (X, Y, Z) in which the X axis extends horizontally and parallel to the vertical wall from the right to the left, the Y axis runs orthogonal to the vertical wall from back to front and the Z axis runs vertically and parallel to the vertical wall from bottom to top.

Dans cet exemple, en référence à la figure 1, chaque rive G, D est adaptée pour être reliée latéralement à une autre rive de banche selon deux points : un point haut PH et un point bas PB. Il va de soi que le nombre de points pourrait plus important en fonction de la hauteur de la banche. Selon un aspect préféré de l'invention, seuls deux points de liaison sont nécessaires pour assurer une liaison. Par la suite, par souci de clarté et de concision, il ne va être présenté qu'une liaison au niveau du point haut PH et du point bas PB.In this example, with reference to the figure 1 , each edge G, D is adapted to be connected laterally to another formwork edge at two points: a high point PH and a low point PB. It goes without saying that the number of points could be greater depending on the height of the panel. According to a preferred aspect of the invention, only two connection points are necessary to ensure a connection. Subsequently, for the sake of clarity and conciseness, only one connection at the level of the high point PH and the low point PB will be presented.

Dans cette forme de réalisation, à la figure 3, la rive gauche G comporte deux dispositifs de liaison 2 positionnés respectivement au niveau du point haut PH et au niveau du point bas PB. La rive droite D comporte deux dispositifs de serrage 3 positionnés respectivement au niveau du point haut PH et au niveau du point bas PB et configurés pour coopérer avec les dispositifs de liaison d'une autre banche. Il va de soi que les dispositifs de liaison 2 et les dispositifs de serrage 3 pourraient être inversés sur les rives G, D de la banche 100.In this embodiment, at the picture 3 , the left bank G comprises two connection devices 2 positioned respectively at the level of the high point PH and at the level of the low point PB. The right bank D comprises two clamping devices 3 positioned respectively at the level of the high point PH and at the level of the low point PB and configured to cooperate with the connection devices of another form. It goes without saying that the connecting devices 2 and the clamping devices 3 could be reversed on the edges G, D of the formwork 100.

Dans cet exemple, les dispositifs de liaison 2 et les dispositifs de serrage 3 utilisés au point haut PH sont analogues à ceux utilisés au point bas PB. Aussi, par souci de clarté et de concision, il ne sera présenté que le dispositif de serrage 2 et le dispositif de liaison 3 utilisés au point haut PH.In this example, the connecting devices 2 and the clamping devices 3 used at the high point PH are similar to those used at the low point PB. Also, for the sake of clarity and conciseness, only the clamping device 2 and the connecting device 3 used at the high point PH will be presented.

RiveShore

En référence à la figure 3, au niveau de son point haut PH, la rive droite D comporte une ouverture haute de réception ODH s'étendant horizontalement et parallèlement à l'axe X selon un axe X-ODH (Figures 6 et 7). De manière similaire, la rive latérale gauche G comporte, au niveau de son point haut PH, une ouverture haute de passage OGH qui s'étend coaxialement à l'ouverture haute de réception ODH de la rive droite D. De manière préférée, les ouvertures hautes ODH, OGH s'étendent à une hauteur verticale de l'ordre de 230 cm.With reference to the picture 3 , at its high point PH, the right bank D has a high reception opening ODH extending horizontally and parallel to the axis X along an axis X-ODH ( Figure 6 and 7 ). Similarly, the left side bank G comprises, at its high point PH, a high passage opening OGH which extends coaxially to the high reception opening ODH of the right bank D. Preferably, the openings high ODH, OGH extend to a vertical height of about 230 cm.

De manière similaire, toujours en référence à la figure 3, au niveau de son point bas PB, la rive droite D comporte une ouverture basse de réception ODB s'étendant horizontalement et parallèlement à l'axe X. De manière similaire, la rive latérale gauche G comporte, au niveau de son point bas PB, une ouverture basse de passage OGB qui s'étend coaxialement à l'ouverture basse de réception ODB de la rive droite D. De manière préférée, les ouvertures basses ODB, OGB s'étendent à une hauteur verticale de l'ordre de 35 cm.Similarly, always with reference to the picture 3 , at its low point PB, the right bank D has a low reception opening ODB extending horizontally and parallel to the axis X. Similarly, the left side bank G has, at its low point PB , a low passage opening OGB which extends coaxially with the low reception opening ODB of the right bank D. Preferably, the low openings ODB, OGB extend to a vertical height of the order of 35 cm .

Chaque ouverture de passage OGH, OGB est associée à un dispositif de liaison 2 tandis que chaque ouverture de réception ODH, ODB est associée à un dispositif de serrage 3.Each passage opening OGH, OGB is associated with a connecting device 2 while each receiving opening ODH, ODB is associated with a tightening device 3.

En référence aux figures 4 et 5, le dispositif de liaison 2 est monté du côté intérieur de la rive gauche G, en particulier, suspendu à la structure de support 101.With reference to figure 4 and 5 , the connecting device 2 is mounted on the inside of the left bank G, in particular, suspended from the support structure 101.

Le dispositif de liaison 2 comporte une tige de liaison 20 sur laquelle est monté un organe de centrage 21 configuré pour coopérer par complémentarité de forme avec l'ouverture haute de passage OGH avec laquelle il est associé. L'organe de centrage 21 est monté en translation sur la tige de liaison 20 de manière à assurer la traction lors d'une liaison entre banches. L'organe de centrage 21 possède une forme évasée ou conique de manière à pouvoir coopérer avec l'ouverture haute de passage OGH formée dans la rive gauche G même lorsque la tige de liaison 20 n'est pas alignée avec l'axe X-OGH de l'ouverture haute de passage OGH.The connecting device 2 comprises a connecting rod 20 on which is mounted a centering member 21 configured to cooperate by shape complementarity with the upper passage opening OGH with which it is associated. The centering member 21 is mounted in translation on the connecting rod 20 so as to provide traction during a connection between panels. The centering member 21 has a flared or conical shape so as to be able to cooperate with the upper passage opening OGH formed in the left bank G even when the connecting rod 20 is not aligned with the axis X-OGH of the upper passage opening OGH.

Dans cet exemple, comme illustré à la figure 5, la tige de liaison 20 comporte une extrémité de connexion 20A qui comporte un trou traversant 201 de manière à pouvoir être broché. La tige de liaison 20 peut être tournée autour de son axe X-OGH de manière à modifier l'orientation du trou traversant 201. De préférence, la tige de liaison 20 comporte une portion filetée 20B, située à l'opposé de l'extrémité de connexion 20A, sur laquelle est vissé un écrou 22. Dans cet exemple, une languette 23 est montée sur la tige de liaison 20, entre l'organe de centrage 21 et l'écrou 22, de manière à suspendre le dispositif de liaison 2 à la banche 100 afin de permettre le déplacement de la tige de liaison 20 selon l'axe X-OGH mais également pour permettre son inclinaison par rapport à l'axe X-OGH, ce qui est avantageux pour relier deux rives de banches qui sont décalées selon l'axe Y ou selon l'axe Z (Figues 12A et 12B).In this example, as shown in figure 5 , the connecting rod 20 has a connection end 20A which has a through hole 201 so that it can be broached. The connecting rod 20 can be turned around its axis X-OGH so as to modify the orientation of the through hole 201. Preferably, the connecting rod 20 comprises a threaded portion 20B, located opposite the end connection 20A, onto which a nut 22 is screwed. In this example, a tab 23 is mounted on the connecting rod 20, between the centering member 21 and the nut 22, so as to suspend the connecting device 2 to the formwork 100 in order to allow the movement of the connecting rod 20 along the X-OGH axis but also to allow its inclination with respect to the X-OGH axis, which is advantageous for connecting two sides of formwork which are shifted along the Y axis or along the Z axis (Figs 12A and 12B).

Un tel dispositif de liaison 2 est connu de l'homme du métier étant donné qu'il est utilisé pour une liaison traditionnelle des rives d'une banche. Aussi, par souci de concision, il ne sera pas présenté plus en détails.Such a connecting device 2 is known to those skilled in the art since it is used for a traditional connection of the edges of a formwork. Also, for the sake of brevity, it will not be presented in more detail.

Un tel dispositif de liaison 2 peut être introduit dans une ouverture de passage d'une autre banche, broché puis serré au moyen d'une clé afin de réaliser une liaison manuelle à l'aide d'une clé de serrage en agissant sur l'écrou 22. De manière avantageuse, la présente invention conserve le dispositif de liaison 2, ce qui permet, d'une part, une compatibilité avec des banches selon l'art antérieur et, d'autre part, un serrage manuel (analogue à l'art antérieur) en cas de défaillance du dispositif de serrage 3.Such a connecting device 2 can be introduced into a passage opening of another formwork, broached then tightened by means of a key in order to carry out a manual connection using a tightening key by acting on the nut 22. Advantageously, the present invention retains the connecting device 2, which allows, on the one hand, compatibility with forms according to the prior art and, on the other hand, manual tightening (similar to the prior art) in the event of failure of the clamping device 3.

En référence aux figures 6 à 9, le dispositif de serrage 3 est monté du côté intérieur de la rive droite D, en particulier, solidaire de la structure de support 101.With reference to figures 6 to 9 , the clamping device 3 is mounted on the inside of the right bank D, in particular, secured to the support structure 101.

Le dispositif de serrage 3 est configuré pour exercer une traction sur la tige de liaison 20 de manière à réaliser le serrage lors de la liaison. Autrement dit, le fonctionnement est inversé à un serrage traditionnel dans lequel le serrage est réalisé du côté de tige de liaison 20 par serrage de l'écrou 22.The clamping device 3 is configured to exert traction on the connecting rod 20 so as to perform the clamping during the connection. In other words, the operation is reversed to a traditional tightening in which the tightening is carried out on the connecting rod 20 side by tightening the nut 22.

En référence à la figure 9, le dispositif de serrage 3 comprend une tête 4, s'étendant en regard de l'ouverture haute de réception ODH, comprenant une cavité ouverte 40 configurée pour recevoir l'extrémité de connexion 20A de la tige de liaison 20. Comme illustré à la figure 7, la cavité ouverte 40 s'étend en regard de l'ouverture haute de réception ODH de manière à ce que l'extrémité de connexion 20A de la tige de liaison 20 pénètre successivement à travers l'ouverture haute de réception ODH puis la cavité ouverte 40. La tête 4 possède de préférence une forme cylindrique. De manière avantageuse, la cavité ouverte 40 possède un diamètre au moins égal à celui de l'ouverture haute de réception ODH afin de permettre une liaison selon diverses inclinaisons de la tige de liaison 20.With reference to the figure 9 , the clamping device 3 comprises a head 4, extending opposite the upper receiving opening ODH, comprising an open cavity 40 configured to receive the connection end 20A of the connecting rod 20. As illustrated in figure 7 , the open cavity 40 extends opposite the upper reception opening ODH so that the connection end 20A of the connecting rod 20 penetrates successively through the upper reception opening ODH then the open cavity 40. The head 4 preferably has a cylindrical shape. Advantageously, the open cavity 40 has a diameter at least equal to that of the upper reception opening ODH in order to allow a connection according to various inclinations of the connecting rod 20.

Dans cet exemple, en référence à la figure 9, la tête 4 comporte deux lumières traversantes 41, 42 diamétralement opposées de manière à permettre un verrouillage comme cela sera présenté par la suite. Il va néanmoins de soi que le verrouillage pourrait être réalisé de manière différente. Dans cette forme de réalisation, la tête 4 possède une longueur de l'ordre de 70mm et un diamètre de l'ordre de 70mm.In this example, with reference to the figure 9 , the head 4 has two through slots 41, 42 diametrically opposed so as to allow locking as will be presented later. It goes without saying, however, that the locking could be carried out in a different way. In this embodiment, the head 4 has a length of the order of 70mm and a diameter of the order of 70mm.

De manière préférée, afin de permettre un verrouillage aisé, les lumières traversantes 41, 42 sont alignées selon un axe de verrouillage U comme illustré à la figure 8 qui est écarté de l'axe Y d'un angle θ compris entre 100° et 170° de manière à permettre un verrouillage optimal du fait de la gravité.Preferably, in order to allow easy locking, the through slots 41, 42 are aligned along a locking axis U as illustrated in figure 8 which is separated from the Y axis by an angle θ of between 100° and 170° so as to allow optimum locking due to gravity.

Le dispositif de serrage 3 comporte en outre un organe de verrouillage 5 configuré pour bloquer ensemble l'extrémité de connexion 20A de la tige de liaison 20 par rapport à la tête 4. Dans cette forme de réalisation, l'organe de verrouillage 5 se présente sous la forme d'une broche adaptée pour pénétrer successivement dans une première lumière traversante 41 de la tête 4, le trou traversant 201 de la tige de liaison 20 et la deuxième lumière traversante 42 de la tête 4. Ainsi, la tête 4 et la tige de liaison 20 sont solidaires en translation selon l'axe X-ODH suite au verrouillage. Il va de soi que l'organe de verrouillage 5 pourrait se présenter sous une forme différente.The clamping device 3 further comprises a locking member 5 configured to block together the connection end 20A of the connecting rod 20 with respect to the head 4. In this embodiment, the locking member 5 is in the form of a pin adapted to penetrate successively into a first through hole 41 of head 4, through hole 201 of connecting rod 20 and second through hole 42 of head 4. Thus, head 4 and connecting rod 20 are integral in translation along the X-ODH axis following locking. It goes without saying that the locking member 5 could be in a different form.

Le dispositif de serrage 3 comporte en outre un organe de déplacement 6 de la tête 4 en translation selon l'axe horizontal X-ODH de l'ouverture haute de réception ODH de manière à venir réaliser un serrage. De manière avantageuse, l'organe de déplacement 6 permet le déplacement de la tête 4 uniquement du côté intérieur de la rive droite D. Autrement dit, l'organe de déplacement 6 ne permet pas de déplacer la tête 4 à travers l'ouverture haute de réception ODH.The clamping device 3 further comprises a member 6 for moving the head 4 in translation along the horizontal axis X-ODH of the upper reception opening ODH so as to perform clamping. Advantageously, the displacement member 6 allows the movement of the head 4 only on the inner side of the right bank D. In other words, the displacement member 6 does not allow the head 4 to be moved through the upper opening ODH reception.

L'organe de déplacement 6 se présente dans cet exemple sous la forme d'un organe hydraulique mais il va de soi qu'il pourrait être électrique, pneumatique ou autre. Notamment, l'organe de déplacement 6 peut se présenter sous la forme d'un organe de transmission mécanique commandé par une visseuse électrique. Ainsi, un opérateur peut réaliser la liaison avec sa visseuse personnelle.The displacement member 6 is in this example in the form of a hydraulic member but it goes without saying that it could be electric, pneumatic or other. In particular, the displacement member 6 can take the form of a mechanical transmission member controlled by an electric screwdriver. Thus, an operator can make the connection with his personal screwdriver.

En particulier, en référence à la figure 9, l'organe de déplacement 6 comporte un cylindre 61 solidaire de la structure de support 101 et une tige de déplacement 62 montée mobile en translation dans le cylindre 61 selon l'axe X-ODH de l'ouverture haute de réception ODH. La tête 4 est fixée à l'extrémité libre de la tige de déplacement 62. De manière préférée, l'organe de déplacement 6, en particulier la tige de déplacement 62, possède une course de déplacement comprise entre 4cm et 8cm.In particular, with reference to the figure 9 , the displacement member 6 comprises a cylinder 61 secured to the support structure 101 and a displacement rod 62 mounted to move in translation in the cylinder 61 along the X-ODH axis of the upper reception opening ODH. The head 4 is fixed to the free end of the displacement rod 62. Preferably, the displacement member 6, in particular the displacement rod 62, has a displacement stroke of between 4cm and 8cm.

Chaque dispositif de serrage 3 évolue ainsi entre une position d'utilisation dans laquelle la tête 4 est éloignée de la rive droite D et une position de repos dans laquelle la tête 4 est proche de la rive droite D.Each tightening device 3 thus moves between a position of use in which the head 4 is away from the right bank D and a rest position in which the head 4 is close to the right bank D.

Dans cet exemple, comme illustré à la figure 8, le cylindre 61 est alimenté par deux canaux hydrauliques 7 afin de commander la tige de déplacement 62 dans les deux sens.In this example, as shown in figure 8 , the cylinder 61 is supplied by two hydraulic channels 7 in order to control the displacement rod 62 in both directions.

Comme illustré à la figure 10, chaque dispositif de serrage 3 est commandé par une unité de commande 8 qui permet de définir la force de traction, c'est-à-dire, la tension de serrage. Cela permet de serrer toutes les banches d'un train de banches de manière analogue et répétable, sans pénibilité. Dans cet exemple, l'unité de commande 8 comporte une pompe hydraulique qui commande l'organe de déplacement 6.As shown in figure 10 , each clamping device 3 is controlled by a control unit 8 which makes it possible to define the tensile force, that is to say, the clamping tension. This makes it possible to tighten all the formwork in a train of formwork in an analogous and repeatable manner, without difficulty. In this example, the control unit 8 comprises a hydraulic pump which controls the displacement member 6.

De manière préférée, les dispositifs de serrage 3 en position haute PH et en position basse PB sont commandés par l'unité de commande 8 de manière à coordonner leurs déplacements comme cela sera présenté par la suite. L'unité de commande 8 est configurée pour commander le déplacement d'un ou plusieurs organes de déplacement 6. De préférence, l'unité de commande 8 est adaptée pour être commandée par une visseuse électrique. Ainsi, un opérateur peut réaliser la liaison avec sa visseuse personnelle.Preferably, the clamping devices 3 in the high position PH and in the low position PB are controlled by the control unit 8 so as to coordinate their movements as will be presented below. The control unit 8 is configured to control the displacement of one or more displacement members 6. Preferably, the control unit 8 is adapted to be controlled by an electric screwdriver. Thus, an operator can make the connection with his personal screwdriver.

De préférence, l'unité de commande 8 comporte un organe de séquençage 81 de manière à coordonner le serrage en position haute PH et en position basse PB. En particulier, l'organe de séquençage 81 est configuré pour n'autoriser un serrage qu'en position basse PB jusqu'à ce qu'un premier seuil de serrage soit atteint, en particulier, de l'ordre d'une tonne. Puis, l'organe de séquençage 81 (valve de séquençage) autorise un serrage en position basse PB et en position haute PH jusqu'à la tension de serrage désirée, ici de l'ordre de 3 tonnes. De manière avantageuse, l'unité de commande 8 permet d'équilibrer les tensions de serrage en position haute PH et en position basse PB. Un tel serrage préliminaire partiel en position basse PB permet de réduire les contraintes mécaniques avant de réaliser un serrage final.Preferably, the control unit 8 comprises a sequencing member 81 so as to coordinate the tightening in the high position PH and in the low position PB. In particular, the sequencing member 81 is configured to only allow tightening in the low position PB until a first tightening threshold is reached, in particular, of the order of one ton. Then, the sequencing member 81 (sequencing valve) allows clamping in the low position PB and in the high position PH until the desired clamping tension, here of the order of 3 tons. Advantageously, the control unit 8 makes it possible to balance the clamping tensions in the high position PH and in the low position PB. Such partial preliminary tightening in the lower position PB makes it possible to reduce the mechanical stresses before carrying out a final tightening.

Un exemple de liaison d'une première banche 100 et d'une deuxième branche 100' va être présenté à la figure 11. La liaison est réalisée en un point haut PH et un point bas PB.An example of connection of a first formwork 100 and a second branch 100' will be presented at the figure 11 . The connection is made at a high point PH and a low point PB.

Tout d'abord, à l'aide d'une grue de levage, les banches 100, 100' sont positionnées l'une à côté de l'autre de manière approximative. Comme illustré aux figures 12A et 12B, les banches sont écartées selon les trois axes X, Y et Z et ne sont pas alignées.First, using a lifting crane, the panels 100, 100' are positioned next to each other approximately. As shown in figure 12A and 12B , the forms are spaced along the three axes X, Y and Z and are not aligned.

Les banches 100, 100' vont être assemblées par liaison de la rive droite D de la première banche 100 à la rive gauche G' de la deuxième banche 100'. Les dispositifs de serrage 3 sont en position de repos de manière à ce que chaque tête 4 soit proche de son ouverture de réception ODH, ODB.Forms 100, 100' will be assembled by linking the right bank D of the first form 100 to the left bank G' of the second form 100'. The clamping devices 3 are in the rest position so that each head 4 is close to its reception opening ODH, ODB.

En référence aux figures 13A et 13B, chaque dispositif de liaison 2' de la deuxième banche 100' est manipulé par un opérateur afin de positionner l'extrémité de connexion 20A' de la tige de liaison 20' dans la tête 4 du dispositif de serrage 3 de la première banche 100. En pratique, chaque tige de liaison 2 peut être orientée de manière à traverser successivement une ouverture de passage OGH' et une ouverture de réception ODH. Un tel dispositif de liaison 2 est simple à manipuler et offre une grande flexibilité pour reprendre des écarts entre les rives D, G'.With reference to figures 13A and 13B , each connecting device 2' of the second form 100' is manipulated by an operator in order to position the connection end 20A' of the connecting rod 20' in the head 4 of the clamping device 3 of the first form 100. In practice, each connecting rod 2 can be oriented so as to pass successively through a passage opening OGH' and a reception opening ODH. Such a connecting device 2 is simple to handle and offers great flexibility in taking up the gaps between the edges D, G'.

Les dimensions de la tête 4 du dispositif de serrage 3 sont adaptées pour autoriser diverses orientations de la tige de liaison 20' tout en permettant à l'extrémité de connexion 20A' d'être logée dans la tête 4. De manière avantageuse, la dimension de l'ouverture traversante 201' dans la tige de liaison 20' est suffisamment grande pour permettre un verrouillage de la tige de liaison 20' selon diverses orientations dans la cavité 40 de la tête 4. Dans cet exemple, un simple brochage de l'organe de verrouillage 5 permet de relier ensemble la tige de liaison 20' et la tête 4. L'orientation de l'axe de verrouillage U permet à l'opérateur un brochage guidé du fait de la gravité et, ce, sans vision des lumières 41, 42 ou de l'ouverture traversante 201 en position haute PH.The dimensions of the head 4 of the clamping device 3 are adapted to allow various orientations of the connecting rod 20' while allowing the connection end 20A' to be housed in the head 4. Advantageously, the dimension of the through opening 201' in the connecting rod 20' is large enough to allow locking of the connecting rod 20' according to various orientations in the cavity 40 of the head 4. In this example, a simple broaching of the locking member 5 makes it possible to connect the connecting rod 20' and the head 4 together. The orientation of the locking axis U allows the operator guided broaching due to gravity and this without vision of the lights 41, 42 or the through opening 201 in the high position PH.

Pour rapprocher les rives D, G', les organes de déplacement 6 des dispositifs de serrage 3 sont commandés par l'unité de commande 8 de manière à ce que les dispositifs de serrage 3 se déplacent en position d'utilisation en exerçant une traction sur les tiges de liaison 20' avec lesquelles les têtes 4 sont reliées. Dans cet exemple, la commande est hydraulique mais elle pourrait également être mise en oeuvre de manière mécanique au moyen d'une visseuse ou autre. De préférence, l'étape de rapprochement est réalisée avec assistance et ne requiert pas de force humaine.To bring the edges D, G' closer together, the displacement members 6 of the clamping devices 3 are controlled by the control unit 8 so that the clamping devices 3 move into the position of use by exerting traction on the connecting rods 20' with which the heads 4 are connected. In this example, the control is hydraulic but it could also be implemented mechanically by means of a screwdriver or the like. Preferably, the approach step is carried out with assistance and does not require human force.

Dans cet exemple de mise en œuvre, une tension de serrage de 3 tonnes est recherchée aussi bien au point haut PH qu'au point bas PB. L'unité de commande 8 comporte un organe de séquençage 81 qui commande tout d'abord un serrage au point bas PB de manière à rapprocher la base des rives D, G'. Tant qu'une tension de serrage d'une tonne n'est pas obtenue au points bas PB, aucun serrage n'est réalisé au point haut PH. Un tel serrage préliminaire au point bas PB permet d'améliorer la liaison en réduisant l'écart entre les centres de gravité des banches 100, 100' et ainsi limiter les efforts au point haut PH lors du serrage final. Lorsqu'une tension de serrage d'une tonne est obtenue au point bas PB, un serrage final est réalisé au point haut PH et au point bas PB avec une tension de serrage de l'ordre de 3 tonnes. Cette séquence de serrage permet de relier de manière rapide deux rives D, G' tout en réduisant les sollicitations mécaniques. Au cours du rapprochement, l'organe de centrage 21' permet d'aligner les banches 100, 100' en centrant l'ouverture de réception ODH avec l'ouverture de passage OGH'.In this implementation example, a clamping tension of 3 tons is sought both at the high point PH and at the low point PB. The control unit 8 comprises a sequencing member 81 which first of all controls tightening at the low point PB so as to bring the base closer to the edges D, G'. As long as a tightening tension of one ton is not obtained at the low points PB, no tightening is carried out at the high point PH. Such preliminary tightening at the low point PB makes it possible to improve the connection by reducing the difference between the centers of gravity of the form panels 100, 100' and thus limiting the forces at the high point PH during the final tightening. When a tightening tension of one ton is obtained at the low point PB, a final tightening is carried out at the high point PH and at the low point PB with a tightening tension of the order of 3 tons. This tightening sequence makes it possible to quickly connect two edges D, G' while reducing the mechanical stresses. During the approximation, the centering member 21' makes it possible to align the formwork panels 100, 100' by centering the reception opening ODH with the passage opening OGH'.

De manière avantageuse, deux banches 100, 100' peuvent être reliées de manière pratique et sans effort par un opérateur du fait de l'assistance de l'organe de serrage 3. La tête 4 de l'organe de serrage 3 est uniquement configurée pour se translater selon l'axe de l'ouverture de réception ODH, ce qui permet une transmission des efforts optimale par comparaison à une tête 4 qui pourrait s'incliner selon diverses orientations. En outre, l'utilisation d'un dispositif de liaison 2 selon l'art antérieur permet de réduire les coûts en autorisant la liaison avec une banche selon l'art antérieur, c'est-à-dire, pourvue d'un dispositif de liaison 2 mais dépourvue d'un dispositif de serrage 3. En outre, en cas de défaillance de l'organe de déplacement 6 du dispositif de serrage 3, un verrouillage demeure toujours possible par l'organe de verrouillage 5. Il suffit à l'opérateur de serrer l'écrou 22 du dispositif de liaison 2 afin de relier les rives D, G'. Autrement dit, même sans assistance, une liaison des rives D, G' est possible, ce qui est avantageux dans un environnement de travail difficile avec des projections de béton.Advantageously, two forms 100, 100' can be connected in a practical manner and without effort by an operator due to the assistance of the clamping member 3. The head 4 of the clamping member 3 is only configured to translate along the axis of the receiving opening ODH, which allows optimum transmission of forces compared to a head 4 which could tilt in various orientations. In addition, the use of a connection device 2 according to the prior art makes it possible to reduce the costs by authorizing the connection with a formwork according to the prior art, that is to say, provided with a device for connection 2 but devoid of a clamping device 3. In addition, in the event of failure of the displacement member 6 of the clamping device 3, locking is still possible by the locking member 5. It is sufficient for the operator to tighten the nut 22 of the connecting device 2 in order to connect the banks D, G'. In other words, even without assistance, a connection of the edges D, G' is possible, which is advantageous in a difficult working environment with concrete projections.
