Dans la description qui va suivre, des chiffres de référence identiques désignent des pièces identiques ou ayant des fonctions similaires.In the following description, like reference numerals designate like parts or having similar functions.

On a représenté à la figure 1 un chantier 12 dans lequel est mis en oeuvre un dispositif 10 selon l'invention.We have shown figure 1 a site 12 in which is implemented a device 10 according to the invention.

De manière connue, le chantier 12 comporte deux parois 14, 15 d'un coffrage 16 de longueur "l" déterminée entre lesquelles un matériau 42 de coulée de construction (non représenté), notamment un matériau 42 de type béton, doit être coulé.In known manner, the site 12 comprises two walls 14, 15 of a formwork 16 of length "l" determined between which a material 42 of casting (not shown), including a material 42 of the concrete type, must be cast.

La réalisation d'un mur complet est ainsi effectuée par coulées successives de tronçons de murs, chaque tronçon de mur étant obtenu par une coulée du matériau 42 dans un coffrage 16 de longueur "I" déterminée.The realization of a complete wall is thus performed by successive castings of wall sections, each wall section being obtained by a casting of the material 42 in a formwork 16 of length "I" determined.

De manière connue, on utilise pour la réalisation d'un tronçon de mur un dispositif d'arrêt vertical 10 comportant au moins une paroi 18 d'arrêt d'orientation sensiblement verticale.In known manner, is used for the production of a wall section a vertical stop device 10 comprising at least one wall 18 stop substantially vertical orientation.

De manière connue, la paroi 18 est mobile entre une position de maintien dans laquelle elle est mise en place avant et pendant la coulée du matériau 42 à une extrémité longitudinale 20 du coffrage 16 et plus particulièrement entre les deux parois 14, 15 du coffrage, et une position d'extraction, vers laquelle elle est mue à l'issue de la coulée, et dans laquelle elle est écartée longitudinalement de sa position de maintien, ici suivant la direction de la flèche "L" pour permettre le démoulage du mur.In known manner, the wall 18 is movable between a holding position in which it is placed before and during the casting of the material 42 at a longitudinal end 20 of the formwork 16 and more particularly between the two walls 14, 15 of the formwork, and an extraction position, to which it is moved at the end of the casting, and wherein it is spaced longitudinally from its holding position, here in the direction of the arrow "L" to allow demolding of the wall.

Conventionnellement, la paroi 18 est rigide et est réalisée à partir d'un panneau de bois. La paroi est agencée à l'extrémité du coffrage 16 entre les deux parois 14, 15 du coffrage par des étais.Conventionally, the wall 18 is rigid and is made from a wooden panel. The wall is arranged at the end of the formwork 16 between the two walls 14, 15 of the formwork by struts.

Cette paroi 18 est démontée une fois le matériau 42 coulé et solidifié.This wall 18 is disassembled once the material 42 cast and solidified.

L'inconvénient de cette conception est que la paroi 18 se retrouve généralement emprisonnée dans le matériau 42 à l'issue du séchage, ce qui rend son démontage difficile.The disadvantage of this design is that the wall 18 is generally trapped in the material 42 after drying, which makes disassembly difficult.

Pour remédier à cet inconvénient, l'invention propose un dispositif 10 du type décrit précédemment, caractérisé en ce qu'il comporte au moins un moyen 22 expansible, qui est destiné à être disposé à l'extrémité 20 longitudinale du coffrage 16, dans ledit coffrage et entre les deux parois 14, 15 du coffrage, qui porte la paroi 18 d'arrêt, et qui est mobile entre une position expansée, représentée à la figure 2, dans laquelle la paroi 18 d'arrêt occupe sa position de maintien, et une position contractée, représentée à la figure 3, dans laquelle la paroi 18 occupe sa position d'extraction.To remedy this drawback, the invention proposes a device 10 of the type described above, characterized in that it comprises at least one expansible means 22, which is intended to be disposed at the longitudinal end of the formwork 16, in said formwork and between the two walls 14, 15 of the formwork, which carries the barrier wall 18, and which is movable between an expanded position, shown in FIG. figure 2 , in which the stop wall 18 occupies its holding position, and a contracted position, represented in FIG. figure 3 , in which the wall 18 occupies its extraction position.

Tout mode de réalisation du moyen 22 expansible peut convenir à la bonne mise en oeuvre de l'invention. Notamment, le moyen 22 peut être un moyen permettant de déplacer mécaniquement la paroi 18, celle-ci étant alors montée sur un moyen de déplacement de type glissière ou crémaillère.Any embodiment of the expandable means 22 may be suitable for the proper implementation of the invention. In particular, the means 22 may be a means for mechanically moving the wall 18, the latter then being mounted on a sliding means of the slide or rack type.

Toutefois, dans le mode de réalisation préféré de l'invention, le moyen expansible 22 comporte au moins un élément gonflable 24 dont une face 26 fait partie de la paroi d'arrêt.However, in the preferred embodiment of the invention, the expansible means 22 comprises at least one inflatable element 24, one face 26 of which is part of the stop wall.

Le dispositif peut comporter un ou plusieurs moyens gonflables 24. S'il n'en comporte qu'un, la face 26 correspond à la paroi d'arrêt 18. S'il en comporte plusieurs, l'ensemble des faces 26 constitue la paroi d'arrêt 18.The device may comprise one or more inflatable means 24. If it has only one, the face 26 corresponds to the stop wall 18. If it comprises more than one, the set of faces 26 constitutes the wall stop 18.

Dans le mode de réalisation préféré de l'invention, chaque élément gonflable 24 est constitué d'un tuyau de type pompier, comportant une paroi interne 25 étanche de doublure délimitant une chambre 27 revêtue d'une enveloppe 29 textile. La face 26 faisant partie de la paroi d'arrêt est donc réalisée en matériau textile. Ce matériau textile n'adhère que peu ou pas au matériau 42 de coulée une fois que celui-ci s'est solidifié.In the preferred embodiment of the invention, each inflatable element 24 consists of a fireman-type pipe, comprising a lining-tight inner wall delimiting a chamber 27 coated with a textile envelope 29. The face 26 forming part of the stop wall is therefore made of textile material. This textile material adheres little or no to the casting material 42 once it has solidified.

Plusieurs modes de réalisation du dispositif 10 peuvent être envisagés, selon la configuration du coffrage 16 qui doit en être équipé.Several embodiments of the device 10 may be envisaged, depending on the configuration of the formwork 16 which must be equipped.

Selon un premier mode de réalisation de l'invention qui a été représenté aux figures 2 et 3, le dispositif 10 est destiné à être associé à un coffrage 16 recevant entre ses parois une armature métallique 28 plane parallèle aux parois 14, 15. Le dispositif 10 comporte deux tuyaux 24 dont chacun est destiné à être agencé entre une face 30, 32 de l'armature métallique plane et la paroi 14, 15 du coffrage 16 en regard.According to a first embodiment of the invention which has been shown in Figures 2 and 3 , the device 10 is intended to be associated with a formwork 16 receiving between its walls a flat metal armature 28 parallel to the walls 14, 15. device 10 comprises two pipes 24 each of which is intended to be arranged between a face 30, 32 of the flat metal frame and the wall 14, 15 of the formwork 16 opposite.

Selon un second mode de réalisation de l'invention qui a été représenté à la figure 4, le dispositif 10 est destiné à être associé à un coffrage 16 recevant entre ses parois au moins deux armatures métalliques planes 28, 29 parallèles aux parois 14, 15, chaque armature 28 étant distante de l'armature 28 consécutive d'un intervalle "l" déterminé.According to a second embodiment of the invention which has been represented at figure 4 , the device 10 is intended to be associated with a formwork 16 receiving between its walls at least two flat metal reinforcements 28, 29 parallel to the walls 14, 15, each armature 28 being spaced from the armature 28 consecutive of an interval "l "determined.

Dans ce cas, le dispositif 10 comporte au moins deux tuyaux 24e d'extrémité, dont chacun est destiné à être agencé entre une face 30, 32 d'une armature métallique plane et la paroi 14, 15 du coffrage en regard, et au moins autant de tuyaux intermédiaires 24i que d'intervalles "I" séparant deux armatures 28 consécutives. Les tuyaux 24i sont reçus dans les intervalles "l".In this case, the device 10 comprises at least two end pipes 24e, each of which is intended to be arranged between a face 30, 32 of a flat metal reinforcement and the wall 14, 15 of the facing formwork, and at least as many intermediate pipes 24i as "I" intervals between two frames 28 consecutive. Pipes 24i are received in intervals "1".

En pratique, la plupart des coffrages 14 de ce type ne comportent que deux armatures 28, 29. Dans ce cas, le dispositif comporte deux tuyaux 24e d'extrémité et un ou deux tuyaux 24i, comme représenté aux figures 4 et 5.In practice, most formwork 14 of this type comprises only two frames 28, 29. In this case, the device comprises two end pipes 24e and one or two pipes 24i, as shown in FIGS. Figures 4 and 5 .

Ainsi, d'une manière générale, chaque intervalle "I" peut ne recevoir qu'un tuyau 24i, comme représenté à la figure 4, ou deux tuyaux 24i jumelés, comme représenté à la figure 5.Thus, in general, each "I" interval may receive only one pipe 24i, as shown in FIG. figure 4 , or two pipes 24i paired, as shown in figure 5 .

Cette configuration est plus particulièrement destinée à être associée à un joint 34 de reprise de coulée.This configuration is more particularly intended to be associated with a casting seal 34.

Dans ce cas, comme l'illustre la figure 5, les tuyaux intermédiaires jumelés 24i sont réunis du côté 36 opposé au matériau de coulée par une membrane 38 de jonction et sont destinés à recevoir du côté du matériau 42 de coulée un joint 34 de reprise de coulée, qui est réalisé sous la forme d'un bande rigide de matériau élastomère. Le joint 34 est reçu entre les deux faces 40 en contact des tuyaux 24i jumelés.In this case, as illustrated by figure 5 the twinned intermediate pipes 24i are joined on the opposite side 36 to the casting material by a connecting membrane 38 and are intended to receive on the side of the casting material 42 a seal 34, which is formed in the form of a rigid band of elastomeric material. The seal 34 is received between the two faces 40 in contact with the twin pipes 24i.

Il sera enfin compris que dans toutes les configurations, le dispositif 10 comporte au moins un moyen 44 de maintien de l'élément expansible 22 à l'extrémité du coffrage 16.It will finally be understood that in all configurations, the device 10 comprises at least one means 44 for holding the expansible element 22 at the end of the formwork 16.

Comme l'illustre la figure 1, ce moyen 44 de maintien est par exemple une planche qui est agencée au contact de l'élément expansible 22 du côté opposé à sa paroi d'arrêt 18, et qui est fixe par rapport au coffrage 16.As illustrated by figure 1 this holding means 44 is for example a board which is arranged in contact with the expansible element 22 on the side opposite its stop wall 18, and which is fixed with respect to the formwork 16.

Dans cette configuration, un procédé de fabrication d'un mur réalisé à partir d'un matériau 42 coulé entre deux parois 14, 15 d'un coffrage 16, comporte au moins deux série d'étapes, les séries d'étapes étant identiques les unes aux autres.In this configuration, a method of manufacturing a wall made from a material 42 cast between two walls 14, 15 of a formwork 16, comprises at least two series of steps, the series of steps being identical to the to each other.

Chaque série d'étape est en effet associée à la coulée d'un tronçon de mur et elle comporte une première étape de mise en place des parois 14, 15 parallèles du coffrage 16,Each series of steps is in fact associated with the casting of a wall section and it comprises a first step of placing parallel walls 14, 15 of the formwork 16,

Puis chaque série d'étapes du procédé comporte une deuxième étape au cours de laquelle on agence au moins un moyen 22 expansible, à l'extrémité longitudinale du coffrage, dans ledit coffrage 16 et entre les deux parois 14, 15 du coffrage, porteur d'une paroi d'arrêt 18 tournée vers l'intérieur du coffrage 15, selon une position expansée. Le moyen expansible 22 est expansé en gonflant chaque tuyau 24, 24e, 24i à l'aide d'une pompe 46.Then each series of steps of the method comprises a second step during which is arranged at least one expansible means 22, at the longitudinal end of the formwork, in said formwork 16 and between the two walls 14, 15 of the formwork, carrying the a stop wall 18 turned towards the inside of the formwork 15, in an expanded position. The expansible means 22 is expanded by inflating each pipe 24, 24e, 24i with a pump 46.

Puis chaque série d'étapes du procédé comporte une troisième étape au cours de laquelle on agence un moyen de maintien 44 au contact du moyen 22 expansible.Then each series of steps of the method comprises a third step during which a holding means 44 is placed in contact with the expansible means 22.

Puis chaque série d'étapes du procédé comporte une quatrième étape au cours de laquelle on effectue une coulée du matériau 42, comme représenté aux figures 2, 4 et 5.Then each series of steps of the method comprises a fourth step during which casting of the material 42, as shown in FIGS. figures 2 , 4 and 5 .

Puis chaque série d'étapes du procédé comporte une cinquième étape (non représentée) de séchage du matériau 42,Then each series of steps of the method comprises a fifth step (not shown) of drying the material 42,

Puis chaque série d'étapes du procédé comporte une sixième étape au cours de laquelle on amène le moyen expansible de sa position expansée à sa position contractée, comme représenté à la figure 3. Ceci est obtenu en vidant chaque tuyau 24, 24e, 24i.Then each series of steps of the method comprises a sixth step during which the expansible means of its expanded position is brought to its contracted position, such as represented at figure 3 . This is achieved by emptying each pipe 24, 24e, 24i.

Enfin, chaque série d'étapes du procédé comporte une septième étape au cours de laquelle on extrait le moyen expansible 22 et le moyen 44 de maintien.Finally, each series of steps of the method comprises a seventh step during which the expansible means 22 and the holding means 44 are extracted.

On peut alors débuter une nouvelle série d'étapes pour construire le tronçon de mur suivant.We can then begin a new series of steps to build the next wall section.

Selon un premier mode de mise en oeuvre du procédé, chaque tuyau 24, 24e, 24i est rempli d'eau au cours de la troisième étape et vidé de l'eau qu'il contient au cours de la sixième étape.According to a first mode of implementation of the method, each pipe 24, 24e, 24i is filled with water during the third stage and emptied of the water it contains during the sixth stage.

En, variante, selon un second mode de mise en oeuvre du procédé, chaque tuyau 24, 24e, 24i est rempli d'air à une pression déterminée au cours de la troisième étape et vidé de l'air qu'il contient au cours de la sixième étape.In a variant, according to a second mode of implementation of the method, each pipe 24, 24e, 24i is filled with air at a determined pressure during the third stage and emptied of the air which it contains during the sixth step.

La pression de l'air dans les tuyaux 24, 24e, 24i est avantageusement contrôlée par un manomètre et régulée pendant toute la prise du matériau.The air pressure in the pipes 24, 24e, 24i is advantageously controlled by a manometer and regulated throughout the setting of the material.

L'invention propose donc un dispositif 10 d'arrêt vertical de matériau de coulée de construction simple et innovant, ne pouvant être emprisonné dans le matériau de coulée à l'issue de la coulée.The invention therefore proposes a device 10 for vertical stop of casting material of simple and innovative construction, which can not be trapped in the casting material at the end of the casting.
