Description

La présente invention concerne le domaine de l'industrie du bâtiment et des travaux publics, en particulier le domaine de la fabrication de matériel de chantier et notamment les dispositifs de coffrage sous forme de banches et a pour objet une banche comprenant un dispositif de bouchage des passages de broches.The present invention relates to the field of the construction industry and public works, in particular the field of the manufacture of construction equipment including formwork devices in the form of bannock and the object is a form including a closure device of the pinways.

Actuellement, le coffrage de murs est généralement effectué au moyen de banches qui sont constituées par une surface de coffrage proprement dite, par des moyens d'appui au sol et de réglage de la verticalité et par des moyens d'assemblage de banches voisines entre elles et qui sont pourvues, en outre, de dispositifs annexes de sécurité, tels que des plateformes de circulation, les divers éléments constitutifs étant assemblés par l'intermédiaire de boulons ou de broches.Currently, the wall formwork is generally carried out by means of panels which are constituted by a formwork surface proper, by ground support means and verticality adjustment and by means of assembling adjoining banches them and which are further provided with ancillary safety devices, such as traffic platforms, the various components being assembled by means of bolts or pins.

Ces banches sont reliées entre elles par l'intermédiaire de broches traversantes s'appuyant sur l'infrastructure des banches, au niveau des poteaux et traversant des passages correspondants sous forme de perçages des peaux coffrantes, ainsi que par des moyens d'assemblage en bout de mur ou de voile et par des moyens d'assemblage hauts consistant en des broches serrant les banches au-dessus de leur bord supérieur. Un tel mode de réalisation permet de répondre de manière satisfaisante aux problème de serrage des banches en position de service. Lorsqu'un coffrage ne nécessite pas de serrage par l'intermédiaire de broches traversantes, les trous de passage de ces broches doivent être bouchés, afin d'éviter un écoulement de béton à travers la face coffrante et d'assurer une finition correcte du mur ou voile coulé au niveau de ces trous.These panels are interconnected by means of through pins based on the substructure of the panels, at the posts and through the corresponding passages in the form of holes of the formwork skins, and by means of end assembly wall or sail and by means of high assembly consisting of pins squeezing the boards over their upper edge. Such an embodiment makes it possible to respond satisfactorily to the problems of clamping the boards in the service position. Where formwork does not require clamping through through pins, the through holes of these pins must be plugged to prevent concrete flow through the formwork face and to ensure a correct wall finish or sail sunk at these holes.

A cet effet, il est généralement mis en oeuvre des bouchons amovibles en matière synthétique, simplement insérés dans les trous de passage des broches par la face avant des peaux coffrantes, ces bouchons s'appuyant par un rebord plat sur ladite face. Ainsi, ces bouchons permettent d'assurer une fermeture satisfaisante de la peau coffrante contre des fuites de béton lors du coulage d'un mur ou d'un voile. Cependant, du fait de la constitution même de ces bouchons, ceux-ci sont soumis à une usure rapide ayant pour conséquence que leur fixation, par léger serrage au montage, n'est pas assurée dans le temps et qu'ils peuvent facilement s'extraire des trous de passage lors des diverses manipulations et ainsi être perdus. Il en résulte des problèmes de disponibilité de ces bouchons en cas de besoin et des pertes de temps conséquentes pour leur recherche ou leur remplacement avec une génération de coût supplémentaire correspondante. En outre, du fait que ces bouchons doivent impérativement être mis en oeuvre sur la face coffrante, un oubli peut entraîner une perte de temps supplémentaire importante.For this purpose, it is generally implemented removable plugs of synthetic material, simply inserted into the through holes of the pins through the front face of the formwork skins, these plugs supported by a flat flange on said face. Thus, these plugs ensure a satisfactory closure of the formwork skin against concrete leaks when pouring a wall or a veil. However, because of the very constitution of these plugs, they are subject to rapid wear resulting in their fixing, by slight tightening assembly, is not assured in time and they can easily s' extract passage holes during various manipulations and thus be lost. This results in problems of availability of these caps when needed and consequent time losses for their search or replacement with a corresponding additional generation of cost. In addition, because these plugs must imperatively be implemented on the formwork side, an oversight can cause a significant loss of additional time.

Des fermetures de passages dans des banches sont notamment connues par FR-A-2 574 840 et par DE-U-87 10 675 . De telles fermetures consistent en des douilles montées de manière affleurante sur un panneau et qui présente une ou plusieurs lèvres pouvant s'écarter élastiquement pour le passage d'une broche et reprenant la position de fermeture lorsque la broche est dégagée. En l'occurrence, il n'est prévu aucun moyen de manoeuvre et de maintien forcé de l'élément de fermeture.Closures of passages in banches are notably known by FR-A-2,574,840 and by DE-U-87 10 675 . Such closures consist of sockets flush mounted on a panel and having one or more lips that can move apart elastically for the passage of a pin and resuming the closed position when the pin is disengaged. In this case, no means of maneuver and forced holding of the closure element are provided.

Les fermetures de ce type permettent, certes, d'éviter la pénétration du béton en position de repos, mais ne sont pas dadptées à la fermeture de passages de broches de banches modernes, qui sont susceptibles d'être soumises à de fortes pressions sur leur paroi, pressions auxquelles ne résisteraient pas ces fermetures. Celles-ci présentent, en effet, une constitution déformable et il est évident qu'une pression élevée à l'intérieur du coffrage aura pour conséquence de les déformer dans le sens d'une ouverture, de sorte qu'un passage sera libéré pour le béton. En fait, ces document prévoient la mise en place de bouchons spécifiques du type évoqué plus haut.Closures of this type make it possible, of course, to prevent the penetration of the concrete in the rest position, but are not dadpted at the closing of modern banister pin passages, which are likely to be subjected to strong pressure on them. wall, pressures that would not resist these closures. These have, indeed, a deformable constitution and it is obvious that a high pressure inside the formwork will have the effect of deforming them in the direction of an opening, so that a passage will be released for the concrete. In fact, these documents provide for the establishment of specific plugs of the type mentioned above.

La présente invention a pour but de pallier ces inconvénients en proposant une banche comprenant un dispositif de bouchage des passages de broches permettant une mise en place rapide et simple et évitant tout risque de perte.The present invention aims to overcome these disadvantages by providing a form including a device for plugging the pin passages for a quick and easy implementation and avoiding any risk of loss.

A cet effet, la banche, qui comprend un dispositif de bouchage des passages de broches prévus, pour chaque broche, au droit d'un poteau d'étaiement d'une banche dans la peau coffrante, est caractérisée en ce que ledit dispositif de bouchage est constitué, pour chaque passage de broche, par un élément de bouchage monté sur une tige de manoeuvre et par une douille de réception de l'élément de bouchage, en position de fermeture du passage de broche, montée coaxialement audit passage de broche, sur la face arrière de la peau coffrante de la banche.For this purpose, the banche, which comprises a device for plugging the pin passages provided for each pin, to the right of a support post of a banche in the formante skin, is characterized in that said closure device is constituted, for each spindle passage, by a closure member mounted on an operating rod and by a receiving sleeve of the closure element, in the closed position of the spindle passage, mounted coaxially with said spindle passage, on the back side of the formant skin of the banche.

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

  • la figure 1 est une vue de dessus d'un dispositif conforme à l'invention en position de service ;
  • la figure 2 est une vue en élévation latérale et en coupe suivant A-A de la figure 1, et
  • la figure 3 est une vue à plus grande échelle, analogue à celle de la figure 2, représentant uniquement l'élément de bouchage monté sur sa tige de manoeuvre.
The invention will be better understood, thanks to the following description, which relates to a preferred embodiment, given as a non-limiting example, and explained with reference to the attached schematic drawings, in which:
  • the figure 1 is a top view of a device according to the invention in the service position;
  • the figure 2 is a side elevation and sectional view along AA of the figure 1 , and
  • the figure 3 is a view on a larger scale, similar to that of the figure 2 , representing only the closure element mounted on its operating rod.

Les figures 1 et 2 des dessins annexés représentent une partie de banche 1 au droit d'un poteau d'étaiement 2, cette banche 1 étant munie de passages de broches 3 dans sa peau coffrante 4. De manière connue, ces passages de broche 3, dont un seul est représenté sur les figures 1 et 2, doivent être bouchés par l'intermédiaire d'un dispositif 5 de bouchage des passages de broches 3, lorsqu'un serrage des banches au moyen de broches n'est pas nécessaire.The figures 1 and 2 appended drawings show a part of box 1 to the right of a shoring post 2, this box 1 being provided with passages of pins 3 in its skin formwork 4. In known manner, these spindle passages 3, of which only one is represented on the figures 1 and 2 , must be plugged by means of a device 5 for plugging the pin passages 3, when clamping the trusses by means of pins is not necessary.

Conformément à l'invention, le dispositif 5 de bouchage des passages de broches 3 est constitué, pour chaque passage de broche 3, par un élément de bouchage 6 monté sur une tige de manoeuvre 7 et par une douille 8 de réception de l'élément de bouchage 6, en position de fermeture du passage de broche 3, montée coaxialement audit passage de broche 3, sur la face arrière de la peau coffrante 4 de la banche 1.According to the invention, the device 5 for plugging the pin passages 3 is constituted, for each pin passage 3, by a plugging element 6 mounted on an operating rod 7 and by a socket 8 for receiving the element. capping 6, in the closed position of the spindle passage 3, mounted coaxially with said spindle passage 3, on the rear face of the formwork skin 4 of the panel 1.

La douille 8 de réception de l'élément de bouchage 6 est montée sur la face arrière de la peau coffrante 4 de la banche 3 par l'intermédiaire d'une collerette de centrage 8' coopérant avec un perçage correspondant 3' du passage de broche 3 et comporte, d'une part, un guidage tronconique 81 s'étendant à partir de sa face opposée à celle comportant la collerette de centrage 8' jusqu'à une butée 81' délimitant avec l'extrémité libre de la collerette de centrage 8' un perçage coaxial 82 et, d'autre part, dans l'extrémité opposée à celle comportant la collerette de centrage 8', un dispositif de verrouillage en position de l'élément de bouchage 6. De préférence, le dispositif de verrouillage en position de l'élément de bouchage 6 est constitué sous forme de rainures à baïonnette 83 ménagées dans le bord correspondant de la douille 8.The bushing 8 for receiving the sealing element 6 is mounted on the rear face of the casing skin 4 of the casing 3 by means of a centering flange 8 'cooperating with a corresponding hole 3' of the spindle passage. 3 and comprises, on the one hand, a frustoconical guide 81 extending from its face opposite to that comprising the centering flange 8 'to a stop 81' delimiting with the free end of the centering flange 8 a coaxial bore 82 and, on the other hand, in the end opposite to that comprising the centering flange 8 ', a locking device in position of the closure element 6. Preferably, the locking device in position of the closure element 6 is formed in the form of bayonet grooves 83 formed in the corresponding edge of the sleeve 8.

Conformément à une caractéristique de l'invention, l'élément de bouchage 6, monté sur la tige de manoeuvre 7, présente, d'une part, une partie d'extrémité 61 sous forme d'un bouchon cylindrique destiné à coopérer, en position de service, avec le perçage coaxial 82 compris entre la butée 81' du guidage tronconique 81 et la collerette de centrage 8' de la douille de réception 8 et pourvu d'un épaulement 61' s'appuyant, en position de service, sur ladite butée 81' du guidage tronconique 81 et, d'autre part, une partie 62 coopérant avec la tige de manoeuvre 7, et pourvue de pattes 63 radialement en saillie et coopérant, en position de service, avec les rainures à baïonnette 83 formant le dispositif de verrouillage en position de l'élément de bouchage 6 de ladite douille de réception 8. La longueur de la partie d'extrémité s'engageant dans le perçage coaxial 82 est égale à celle de ce perçage coaxial 82 comprise entre la face d'appui de la butée 81' et l'extrémité libre de la collerette de centrage 8' de la douille de réception 8.According to a characteristic of the invention, the blocking element 6, mounted on the operating rod 7, has, on the one hand, an end portion 61 in the form of a cylindrical plug intended to cooperate, in the operating position, with the coaxial bore 82 between the abutment 81 'of the frustoconical guide 81 and the centering flange 8' of the receiving sleeve 8 and provided with a shoulder 61 'bearing, in a position of service, on said stop 81 'of the frustoconical guide 81 and, secondly, a portion 62 cooperating with the actuating rod 7, and provided with tabs projecting radially and cooperating, in the operating position, with the bayonet grooves 83 forming the locking device in position of the closure member 6 of said receiving sleeve 8. The length of the end portion engaging in the coaxial bore 82 is equal to that of this coaxial bore 82 between the bearing face of the stop 81 'and the free end of the centering flange 8' of the receiving sleeve 8.

Ainsi, l'invention permet une mise en service du dispositif par l'arrière de la banche 1, quelle que soit la position de cette dernière. En effet, grâce à la tige de manoeuvre 7, l'élément de bouchage 6 est simplement inséré, par sa partie d'extrémité 61 à travers le guidage tronconique 81 de la douille de réception 8, puis le perçage coaxial 82, jusqu'à entrer en contact avec la butée 81' avec son épaulement 61'. Les pattes radiales 63 de la partie 62 destinée à coopérer avec la tige de manoeuvre 7 sont alors insérées, par rotation au moyen de la tige de manoeuvre 7, dans les rainures à baïonnette 83, pour le maintien en position de l'ensemble.Thus, the invention allows a commissioning of the device from the back of the panel 1, whatever the position of the latter. Indeed, thanks to the operating rod 7, the closure member 6 is simply inserted, by its end portion 61 through the frustoconical guide 81 of the receiving sleeve 8, and the coaxial drilling 82, to come into contact with the stop 81 'with its shoulder 61'. The radial lugs 63 of the portion 62 intended to cooperate with the actuating rod 7 are then inserted, by rotation by means of the operating rod 7, into the bayonet grooves 83, for holding the assembly in position.

L'élément de bouchage 6 est monté sur la tige de manoeuvre 7 par l'intermédiaire d'un manchon cylindrique creux 61", prévu coaxialement et du côté opposé à sa partie d'extrémité 61 et relié à ladite tige de manoeuvre 7, par collage, par soudage ou par frettage.The blocking element 6 is mounted on the operating rod 7 by means of a hollow cylindrical sleeve 61 ", provided coaxially and on the side opposite its end portion 61 and connected to said operating rod 7, by bonding, by welding or by frettage.

Selon une autre caractéristique de l'invention, la partie 62, destinée à coopérer avec la tige de manoeuvre 7 et pourvue de pattes 63 radialement en saillie, se présente avantageusement sous forme d'une douille taraudée portant les pattes radiales 63 et est vissée par son taraudage sur un filetage correspondant du manchon cylindrique creux 61" de l'élément de bouchage 6. Ainsi, il est possible de régler précisément la position des pattes 63 par rapport à la partie d'extrémité 61, de sorte que cette dernière peut être parfaitement appliquée sur la butée 81' du guidage tronconique 81 de la douille 8 avec son épaulement 61' et que sa face affleure avec celle de la peau coffrante 4 de la banche 1.According to another characteristic of the invention, the portion 62 intended to cooperate with the actuating rod 7 and provided with radially projecting lugs 63 is advantageously in the form of a threaded socket carrying the radial lugs 63 and is screwed by its tapping on a corresponding thread of the hollow cylindrical sleeve 61 "of the closure member 6. Thus, it is possible to precisely adjust the position of the tabs 63 relative to the end portion 61, so that the latter can be perfectly applied to the abutment 81 'of the frustoconical guide 81 of the sleeve 8 with its shoulder 61' and that its face is flush with that of the formant skin 4 of the panel 1.

En effet, lors de la mise en place du dispositif 5 de bouchage d'un passage de broche 3, l'élément de bouchage 6 est inséré, au moyen de la tige de manoeuvre 7, d'abord dans le guidage tronconique 81 de la douille 8, puis dans le perçage coaxial 82 jusqu'à ce que son épaulement 61' vienne en contact avec la butée 81'. Dans cette position, les pattes 63 de la partie 62, qui coopère avec la tige de manoeuvre 7, pénètrent dans les rainures à baïonnette 83 de la douille 8.Indeed, when setting up the device 5 for plugging a spindle passage 3, the closure element 6 is inserted, by means of the operating rod 7, first in the frustoconical guide 81 of the sleeve 8, then in the coaxial bore 82 until its shoulder 61 'comes into contact with the stop 81'. In this position, the tabs 63 of the part 62, which cooperates with the operating rod 7, penetrate into the bayonet grooves 83 of the sleeve 8.

Une rotation de la tige de manoeuvre 7 permet alors d'amener ces pattes 63 dans leur position de verrouillage. Du fait du montage de la partie 62 en forme de douille taraudée sur un filetage correspondant du manchon cylindrique creux 61" de l'élément de bouchage 6, il est alors possible, par une poursuite du mouvement de rotation de la tige de manoeuvre 7, de déplacer l'élément de bouchage 6 en translation pour l'appliquer à force sur la butée 81', par son épaulement 61', les pattes 63 de la partie 62 étant appuyées à fond dans les rainures à baïonnette 83 de la douille 8, de sorte que l'extrémité libre de la partie 61 affleure avec la peau coffrante 4. Il en résulte qu'il est possible de réaliser un guidage d'approche de l'élément de bouchage 6 suivi d'un guidage final avec affleurement de l'extrémité libre de cet élément sur la face coffrante tout en assurant un maintien parfait dudit élément de bouchage après sa mise en place, le maintien étant particulièrement stable et résistant à la pression et aux vibrations. Pour le démontage de l'élément de bouchage 6, il suffit de réaliser la manoeuvre inverse, à savoir de dévisser d'abord légèrement la tige de manoeuvre 7 afin de déplacer la partie 62 pour soulever légèrement la partie d'extrémité 61, puis de tourner la partie 62 avec les pattes 63 pour dégager ces dernières en direction de la sortie des rainures à baïonnette 83. L'ensemble peut alors être entièrement retiré.A rotation of the operating rod 7 then makes it possible to bring these lugs 63 into their locking position. Due to the fitting of the threaded sleeve-shaped portion 62 on a corresponding thread of the hollow cylindrical sleeve 61 "of the sealing member 6, it is then possible, by continuing the rotational movement of the operating rod 7, to move the closure member 6 in translation to apply it forcefully to the stop 81 ', by its shoulder 61', the tabs 63 of the portion 62 being pressed fully in the bayonet grooves 83 of the sleeve 8, so that the free end of the portion 61 is flush with the form skin 4. It follows that it is possible to achieve a guidance approach of the closure member 6 followed by a final guide with flush with the free end of this element on the formwork side while ensuring a perfect maintenance of said closure member after its introduction, the maintenance being particularly stable and resistant to pressure and vibration.For disassembly of the closure element 6 , it suffices to perform the opposite operation, namely to unscrew the actuating rod 7 first to move the portion 62 to slightly lift the end portion 61, then to turn the portion 62 with the tabs 63 to clear these latter towards the exit of the bayonet grooves 83. The assembly can then be entirely removed.

Conformément à une autre caractéristique de l'invention, afin de pouvoir effectuer une manoeuvre facile de la tige de manoeuvre 7, cette dernière est avantageusement pourvue à son extrémité libre d'une poignée de manoeuvre 7', cette poignée 7' pouvant être munie, en outre, d'un perçage radial 71' de passage d'une tige de manoeuvre non représentée. Ainsi, il est possible à tout opérateur de manoeuvrer très facilement la tige 7 ce, tant pendant le guidage d'approche que pendant la plus grande partie du guidage final et du serrage correspondant, le serrage final pouvant être effectué par insertion d'une tige ou analogue dans le perçage radial 71'.According to another characteristic of the invention, in order to be able to easily maneuver the operating rod 7, the latter is advantageously provided at its free end with an operating handle 7 ', this handle 7' being able to be provided, in addition, a radial bore 71 'passing through a not shown operating rod. Thus, it is possible for any operator to very easily maneuver the rod 7 ce, both during the approach guidance and during most of the final guide and the corresponding clamping, the final tightening can be performed by inserting a rod or the like in the radial bore 71 '.

Par ailleurs, la tige de manoeuvre 7 peut aussi être munie d'un moyen 9 de retenue de l'ensemble, que forme la tige 7 avec l'élément de bouchage 6, sur la banche 1, ce moyen étant préférentiellement constitué sous forme d'une platine montée de manière libre en rotation sur l'extrémité de la tige de manoeuvre 7, sous la poignée de manoeuvre 7', cette platine pouvant être reliée à la banche 1 par l'intermédiaire d'un câble ou d'une chaînette (non représentée). Avantageusement, le câble ou la chaînette est relié à la banche 1 par l'intermédiaire d'une plaquette 10 intégrée dans le poteau d'étaiement 2 et pourvue, d'une part, d'une encoche 10' ou d'un oeillet de réception d'une extrémité du câble ou de la chaînette et, d'autre part, d'un évidement 10" de logement de la tige de manoeuvre 7 en position de non utilisation, ladite tige de manoeuvre 7 reposant alors sur ladite plaquette 10 par l'intermédiaire de la platine formant le moyen de retenue 9. La prévision de ce moyen de retenue 9 permet d'éviter tout risque de perte de l'élément de bouchage 6, en particulier lorsqu'il n'est pas en position de service.Furthermore, the operating rod 7 may also be provided with a means 9 for retaining the assembly, which forms the rod 7 with the closure element 6, on the panel 1, this means being preferably constituted in the form of a plate freely rotatably mounted on the end of the actuating rod 7, under the operating handle 7 ', this plate can be connected to the form 1 by means of a cable or a chain (not shown). Advantageously, the cable or the chain is connected to the wall 1 by means of a plate 10 integrated in the shoring pole 2 and provided, on the one hand, with a notch 10 'or an eyelet of receiving an end of the cable or the chain and, secondly, a recess 10 "housing of the operating rod 7 in the non-use position, said operating rod 7 then resting on said plate 10 by through the platen forming the retaining means 9. The provision of this retaining means 9 avoids any risk of loss of the closure member 6, particularly when not in the service position .

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