Description

La présente invention est relative à un dispositif pour réaliser de manière simple une structure en béton comportant au moins un fond et des parois latérales.The present invention relates to a device for simply producing a concrete structure comprising at least one bottom and side walls.

On sait que,pour édifier par exemple un réservoir en béton cylindrique ou polygonal,on réalise tout d'abord un radier sur une surface de propreté, cette dernière étant constituée par le sol lui-même traité d'une manière appropriée, ou par une surface appartenant à une structure préalablement construite. Puis,au moyen d'un coffrage à deux parois, l'une intérieure, l'autre extérieure, on réalise un espace dans lequel on place généralement une armature métallique puis on coule le béton des parois latérales du réservoir.We know that, to build, for example, a cylindrical or polygonal concrete tank, we first make a slab on a cleanliness surface, the latter consisting of the soil itself treated in an appropriate manner, or by a surface belonging to a previously constructed structure. Then, by means of a formwork with two walls, one interior, the other exterior, a space is created in which a metal frame is generally placed and then the concrete is poured from the side walls of the tank.

L'invention concerne une solution simple, économique et rapide à mettre en oeuvre pour réaliser la confection du radier et des parois latérales d'un réservoir qui consiste en un coffrage particulier conçu pour diminuer au maximum les opérations de montage et démontage. Ce coffrage particulier est assorti d'un certain nombre d'accessoires formant avec lui le dispositif de l'invention.The invention relates to a simple, economical and quick solution to implement for making the raft and the side walls of a tank which consists of a particular formwork designed to minimize assembly and disassembly operations. This particular formwork is accompanied by a number of accessories forming with it the device of the invention.

L'invention a donc pour objet un dispositif caractéristique en ce qu'il comprend un coffrage extérieur constitué par panneaux,dressé sur une surface inférieure de propreté et comportant à sa partie supérieure une console périphérique extérieure, et un chariot susceptible d'être déplacé et guidé le long de cette console périphérique, ledit chariot formant bâti mobile pour des organes amovibles de coulée.The subject of the invention is therefore a device which is characteristic in that it comprises an external formwork constituted by panels, erected on a lower cleanliness surface and comprising at its upper part an external peripheral console, and a carriage capable of being moved and guided along this peripheral console, said carriage forming a movable frame for removable casting members.

Pour la réalisation du fond de la structure, l'un des organes amovibles susdits est constitué par une potence attelée par sa partie supérieure audit chariot et comportant une partie en forme d'étrier vertical courant le long de la face interne du coffrage et possédant dans sa partie inférieure une traverse horizontale réglable en position le long de l'étrier et formant support pour l'extrémité d'une règle de nivellement du fond.To produce the bottom of the structure, one of the above-mentioned removable members consists of a bracket coupled by its upper part to said carriage and comprising a part in the form of a vertical stirrup running along the internal face of the formwork and having in its lower part a horizontal crosspiece adjustable in position along the stirrup and forming a support for the end of a leveling rule of the bottom.

En outre,on aura prévu un support destiné à être noyé dans le fond et centré sur l'axe de symétrie du coffrage et comportant un axe d'articulation pour l'autre extrémité de la règle susdite.In addition, there will be provided a support intended to be embedded in the bottom and centered on the axis of symmetry of the formwork and comprising an axis of articulation for the other end of the above rule.

Après la réalisation du fond et pour l'édification des parois latérales, le dispositif selon l'invention comporte en outre un coffrage intérieur constitué par panneaux équipé, au voisinage de sa base, de butées réglables faisant saillie à l'extérieur du coffrage intérieur pour déterminer l'épaisseur de la paroi de la structure et escamotables vers le centre de cette dernière.After the completion of the bottom and for the construction of the side walls, the device according to the invention further comprises an internal formwork constituted by panels equipped, in the vicinity of its base, with adjustable stops protruding outside the internal formwork for determine the thickness of the wall of the structure and retractable towards the center of the latter.

Il est alors avantageux de prévoir l'un des . panneaux constitutifs dudit coffrage intérieur de largeur réglable au moyen d'un bord vertical mobile et comportant une plaque extérieure de recouvrement du bord vertical mobile et du bord du panneau adjacent audit bord mobile.It is therefore advantageous to provide one of the. constituent panels of said interior formwork of adjustable width by means of a movable vertical edge and comprising an outer plate covering the movable vertical edge and of the edge of the panel adjacent to said movable edge.

En outre une passerelle latérale interne pourra être disposée le long du coffrage intérieur susdit. Pour la réali- sationdes parois, on aura remplacé la potence susdite sur le chariot par un autre organe amovible de coulée constitué par une benne articulée audit chariot susceptible d'être déversée latéralement par basculement autour de son axe d'articulation.In addition, an internal lateral walkway may be arranged along the above-mentioned interior formwork. For the realization of the walls, the above-mentioned bracket on the carriage will have been replaced by another removable casting member constituted by a bucket articulated to said carriage capable of being discharged laterally by tilting around its axis of articulation.

Dans cette version,1e chariot pourra comporter une plaque latérale fixe par rapport à la benne qui constitue l'élément de fermeture et de réglage de l'ouverture de déversement de la benne.In this version, the trolley may include a fixed side plate with respect to the bucket which constitutes the element for closing and adjusting the opening of the dumping of the bucket.

L'invention sera mieux comprise au cours de la description donnée ci-après à titre d'exemple purement indicatif et non limitatif qui permettra d'en dégager les avantages et les caractéristiques secondaires.The invention will be better understood during the description given below by way of purely indicative and nonlimiting example which will make it possible to identify the advantages and the secondary characteristics thereof.

Il sera fait référence aux dessins annexés dans lesquels :

  • - la figure 1 est une vue schématique partielle du dispositif selon l'invention pour la confection du fond d'une structure,par exemple le radier d'un réservoir;
  • - la figure 2 est une vue de dessus partielle de la figure 1 et illustre un élément constitutif de la console extérieure de roulement du chariot;

  • - les figures 5A et 5B sont des vues de profil schématiques du chariot selon l'invention équipé de sa benne.
Reference will be made to the appended drawings in which:
  • - Figure 1 is a partial schematic view of the device according to the invention for making the bottom of a structure, for example the raft of a tank;
  • - Figure 2 is a partial top view of Figure 1 and illustrates a component of the outer carriage rolling console;

  • - Figures 4 and 4A illustrate a panel extendable in width of the interior formwork;
  • - Figures 5A and 5B are schematic side views of the trolley according to the invention equipped with its bucket.

En se reportant tout d'abord à la figure 1, on voit, sur une surface de propreté 1 (par exemple le sol préparé par une couche de ciment ou une surface supérieure d'une structure déjà bâtie), un coffrage 2 vu en coupe. Ce coffrage est constitué par une juxtaposition de panneaux ou banches qui seront cintrés si le coffrage est cylindrique. L'assemblage de ces panneaux est réalisé au moyen de tout organe approprié (clavettes, boulons) et est affermi par au moins un câble 3 de ceinturage du coffrage. Ce câble peut avantageusement courir dans une gouttière 4 et l'une de ses fonctions secondaires sera exposée ultérieurement.Referring first to Figure 1, we see, on a cleanliness surface 1 (for example the floor prepared by a layer of cement or an upper surface of an already built structure), a formwork 2 seen in section . This formwork is made up of a juxtaposition of panels or forms which will be bent if the formwork is cylindrical. The assembly of these panels is carried out by means of any suitable member (keys, bolts) and is strengthened by at least one cable 3 for belting the formwork. This cable can advantageously run in a gutter 4 and one of its secondary functions will be explained later.

Lesdits panneaux ou banches sont constitués de manière connue par des plaques métalliques ou de contre-plaqué ou d'un autre matériau approprié qui sont fixées sur un cadre mis en forme et quadrillé de cornières de raidissement.Said panels or forms are formed in a known manner by metal plates or plywood or other suitable material which are fixed on a shaped frame and grid of stiffening angles.

Chaque panneau possède au moins un bras 5 articulé à sa partie supérieure en 5a et maintenu sensiblement horizontal par une jambe de force 6 articulée par son extrémité 6a sur le bras 5 et reposant par son extrémité 6b sur une cornière de raidis- sage horizontale du panneau au moyen d'une cornière complémentaire. Ainsi;l'aile horizontale de cette cornière complémentaire qui équipe l'extrémité 6b de la jambe de force 6 prend appui sur la cornière horizontale du panneau,tandis que l'aile verticale de cette cornière complémentaire se prolonge jusqu'au niveau de la gouttière 4 et peut être fermement retenue par le câble de ceinturage 3 contre la banche.Each panel has at least one arm 5 articulated at its upper part at 5a and maintained substantially horizontal by a strut 6 articulated by its end 6a on the arm 5 and resting at its end 6b on a horizontal stiffening angle of the panel. by means of an additional angle. Thus, the horizontal wing of this complementary angle which equips the end 6b of the strut 6 bears on the horizontal angle of the panel, while the vertical wing of this complementary angle extends up to the level of the gutter. 4 and can be firmly retained by the belt cable 3 against the sheet.

Lesdits bras 5 constituent ainsi des supports repliables pour une console périphérique 7 constituée par secteurs (si le coffrage est cylindrique) ou tronçons 7a (voir figure 2). Chacun de ces secteurs 7a est constitué d'une plaque 8 reposant et fixée sur un cadre approprié dont on a représenté des éléments radiaux 9, une bordure périphérique 10 intérieure constituée par une cornière et un élément périphérique extérieur 11 constitué par exemple par un profilé à section carrée ou rectangulaire. L'aile verticale de la cornière 10 et la paroi verticale tournée vers le coffrage du profilé 11 forment les parois latérales d'un rail de guidage dont la fonction sera exposée ci-après. L'élément 9 central de soutien de la plaque 8 est pourvu d'une extrémité intérieure 9a conformée de manière à constituer un doigt d'indexation du secteur de console 7a sur la banche, en coopérant avec un orifice correspondant prévu à l'extrémité supérieure de cette dernière. On aura remarqué sur la figure 1 que le bras 5 possède une extrémité 5b verticale qui s'étend à l'extérieur de la console 7 qui,de ce fait, constitue un élément de retenue radiale de cette dernière et peut être en outre utilisé comme organe d'enfichage d'une barrière de sécurité amovible encerclant la console. Par ailleurs, il faut noter que la plaque 8 s'étend en direction de l'axe central du coffrage de manière à recouvrir le sommet des banches: Enfin, on remarquera sur la figure 2 que l'un des éléments radiaux 9b bordant latéralement le secteur 7a déborde de manière à constituer une surface d'appui pour le secteur adjacent. Le profilé 11 sera taillé à chacune de ses extrémités de manière complémentaire l'une de l'autre afin qu'aucune solution de continuité n'apparaisse dans la console complète. Dans le cas ou un seul bras 5 est prévu par banche,celui- ci sera disposé de manière à soutenir les tronçons au voisinage de l'élément 9b, chaque tronçon 7a étant alors soutenu par un bras 5 à l'une de ses extrémités, par la partie débordante de l'élément 9b de la console adjacente à son autre extrémité et par l'ergot 9a coopérant avec la banche dans sa partie médiane.Said arms 5 thus constitute foldable supports for a peripheral console 7 constituted by sectors (if the formwork is cylindrical) or sections 7a (see FIG. 2). Each of these sectors 7a consists of a plate 8 resting and fixed on a suitable frame of which radial elements 9 have been shown, an inner peripheral edge 10 constituted by an angle iron and an external peripheral element 11 constituted for example by a profile with square or rectangular section. The vertical wing of the angle iron 10 and the vertical wall facing the formwork of the profile 11 form the side walls of a guide rail whose function will be explained below. The central support element 9 of the plate 8 is provided with an inner end 9a shaped so as to constitute an indexing finger of the console sector 7a on the panel, cooperating with a corresponding orifice provided at the upper end of the latter. It will have been noticed in FIG. 1 that the arm 5 has a vertical end 5b which extends outside the console 7 which, therefore, constitutes a radial retaining element of the latter and can also be used as device for inserting a removable safety barrier surrounding the console. Furthermore, it should be noted that the plate 8 extends in the direction of the central axis of the formwork so as to cover the top of the forms: Finally, it will be noted in FIG. 2 that one of the radial elements 9b laterally bordering the sector 7a overflows so as to constitute a bearing surface for the adjacent sector. The profile 11 will be cut at each of its ends in a complementary manner to each other so that no continuity solution appears in the complete console. In the case where only one arm 5 is provided per section, the latter will be arranged so as to support the sections in the vicinity of the element 9b, each section 7a then being supported by an arm 5 at one of its ends, by the projecting part of the element 9b of the console adjacent to its other end and by the lug 9a cooperating with the cover in its middle part.

Une telle console 7 est ainsi adaptée pour recevoir un chariot 12 qui est constitué par un châssis tubulaire sensiblement plan 13 pourvu d'éléments de roulement 14a sur le bord intérieur de la console, d'éléments de roulement 14b sur la surface supérieure du profilé 11 et de galets 14c de guidage de ce châssis placés entre les parois du rail définies ci-avant. Ce chariot, qui peut donc décrire en y étant guidé toute la console 7, constitue un support pour des organes accessoires de coulée pour réaliser d'une part le radier du réservoir et d'autre part les parois latérales de ce dernier.Such a console 7 is thus adapted to receive a carriage 12 which is constituted by a substantially flat tubular chassis 13 provided with rolling elements 14a on the inside edge of the console, rolling elements 14b on the upper surface of the profile 11 and rollers 14c for guiding this chassis placed between the walls of the rail defined above. This carriage, which can therefore be described while being guided therein, the entire console 7, constitutes a support for accessory casting members to produce on the one hand the base of the tank and on the other hand the side walls of the latter.

Pour la réalisation du radier,on équipe le chariot 12 (figures 1 et 2) d'une potence 15 dont la partie supérieure 15a est fixéeau châssis 13 et dont l'autre partie 15b s'étend verticalement le long du coffrage 2 et forme avec une traverse de base 15c un support pour l'extrémité 16a d'une règle 16 de nivellement. La traverse 15c peut être réglée en hauteur le long de la partie verticale 15b selon l'épaisseur désirée du radier. L'autre extrémité 16b de la règle peut pivoter autour d'un axe vertical porté par un élément de centrage et de support 17 destiné à être noyé dans le radier. Cet élément 17 est bien entendu placé au centre du fond du réservoir.For the realization of the raft, one equips the carriage 12 (Figures 1 and 2) with a bracket 15 whose upper part 15a is chassis frame 13 and the other part 15b of which extends vertically along the formwork 2 and forms, with a base cross member 15c, a support for the end 16a of a leveling rule 16. The cross member 15c can be adjusted in height along the vertical part 15b according to the desired thickness of the raft. The other end 16b of the rule can pivot around a vertical axis carried by a centering and support element 17 intended to be embedded in the raft. This element 17 is of course placed in the center of the bottom of the tank.

Pour réaliser le radier, on déverse donc du béton au fond de l'espace intérieur du coffrage 2 par petites quantités, après avoir réalisé l'armature nécessaire, que l'on étale grossièrement à la main, puis que l'on nivelle au moyen de la règle 16 en faisant tourner cette dernière sur une amplitude correspondant à la longueur de la traverse 15c. Dans le même temps, on vibre le béton et à cet égard on peut noter que la règle 16 peut être vibrante ou équipée d'aiguille vibrante. Le secteur situé sous la règle étant nivelé et vibré, on avance le chariot 12 d'une valeur angulaire correspondant audit secteur et l'on procède de la même manière pour niveler le secteur adjacent. On réalise ainsi un radier soit parfaitement plan,soit conique,pointe vers le bas ou vers le haut selon le réglage de la règle.To make the slab, we pour concrete at the bottom of the interior space of the formwork 2 in small quantities, after having made the necessary reinforcement, which is spread roughly by hand, then leveled by means of rule 16 by rotating the latter over an amplitude corresponding to the length of the cross member 15c. At the same time, the concrete is vibrated and in this regard it can be noted that the rule 16 can be vibrating or equipped with vibrating needle. The sector located under the ruler being leveled and vibrated, the carriage 12 is advanced by an angular value corresponding to said sector and the same procedure is followed to level the adjacent sector. We thus realize a raft either perfectly flat or conical, point down or up depending on the setting of the rule.

Lorsque le radier 18 (figure 3) est réalisé et suffisamment pris, après avoir retiré la potence 15 et la règle 16, on procède au montage du coffrage intérieur 20,lui aussi constitué de banches ou panneaux assemblés les uns aux autres. Ce coffrage inférieur 20 est équipé au voisinage de sa base de butée d'entretoisement 21 dont la longueur en saillie à l'extérieur du coffrage intérieur est réglable (en fonction de l'épaisseur e des parois à réaliser) qui soit escamotable vers l'intérieur du réservoir après que l'on a coulé une certaine hauteur de béton.When the raft 18 (Figure 3) is made and sufficiently taken, after removing the bracket 15 and the rule 16, we proceed to the assembly of the inner formwork 20, also consisting of forms or panels assembled to each other. This lower formwork 20 is equipped in the vicinity of its bracing stop base 21, the length of which protrudes outside the internal formwork is adjustable (as a function of the thickness e of the walls to be produced) which is retractable towards the inside the tank after a certain height of concrete has been poured.

Les banches constitutives du coffrage intérieur 20 comportent des supports 22 articulés en 22a à leur partie supérieure et comportant une partie horizontale 22b capable de soutenir une passerelle interne courant tout autour et à l'intérieur du coffrage 20.The formwork forming the interior formwork 20 comprises supports 22 articulated at 22a at their upper part and comprising a horizontal part 22b capable of supporting an internal gangway running all around and inside the formwork 20.

Sur les figures 4 et 4a, on a représenté schématiquement l'une des banches 20a du coffrage 20 particulière en ce qu'elle comporte un bord latéral 23 mobile au moyen de tiges filetées 24 solidaires de ce bord, guidées en translation dans une cornière 25 et coopérant avec des écrous 26 qui, manoeuvrés en rotation, permettent d'éloigner le bord 23 d'un élément 27 fixe de la banche 20a. En poussant ainsi le bord 23 contre le bord adjacent de la banche 20b voisine, on arc-boute toutes les hanches entre elles et assure une bonne stabilité au corffrage interne à l'encontre de la pression du béton coulé. On aura noté enfin qu'une plaque 28 solidaire de la banche 20a couvre la plage de mobilité du bord 23 et recouvre en pouvant y -glisser le bord de la banche 20b. Cette plaque 28 assure l'étanchéité du coffrage à cet endroit.In Figures 4 and 4a, there is shown schematically one of the forms 20a of the particular formwork 20 in that it comprises a lateral edge 23 movable by means of threaded rods 24 integral with this edge, guided in translation in an angle 25 and cooperating with nuts 26 which, maneuvered in rotation, make it possible to move the edge 23 away from a fixed element 27 of the panel 20a. By thus pushing the edge 23 against the adjacent edge of the neighboring panel 20b, all of the hips are arched together and ensures good stability to the internal corrugation against the pressure of the poured concrete. Finally, it will have been noted that a plate 28 integral with the panel 20a covers the range of mobility of the edge 23 and covers by being able to slide the edge of the panel 20b therein. This plate 28 seals the formwork at this location.

Enfin,les figures 5A et 5B montrent un équipement du chariot 12 par un autre organe de coulée, à savoir une benne 30. Sur ces figures, on retrouve certains des éléments déjà décrits avec les mêmes références. Pour recevoir ladite benne, le chariot 12 est équipé d'un axe longitudinal 31 susceptible d'être chevauché par des étriers 32 disposés sous le fond de la benne. Ces étriers coopèrent donc avec l'axe 31 qui constitue un axe d'articulation autour duquel la benne 30 peut basculer latéralement,comme cela est indiqué en trait mixte 30' sur la figure 5B. On peut ainsi déverser son contenu entre les deux coffrages 2 et 20, la benne 30 étant conformée de manière à ne pas présenter de paroi latérale du côté des coffrages.Finally, FIGS. 5A and 5B show an equipment of the carriage 12 by another casting member, namely a bucket 30. In these figures, we find some of the elements already described with the same references. To receive said bucket, the carriage 12 is equipped with a longitudinal axis 31 capable of being overlapped by stirrups 32 arranged under the bottom of the bucket. These stirrups therefore cooperate with the axis 31 which constitutes a hinge axis around which the bucket 30 can tilt laterally, as indicated in phantom 30 'in Figure 5B. Its content can thus be poured between the two forms 2 and 20, the bucket 30 being shaped so as not to have a side wall on the side of the forms.

La manoeuvre en basculement de la benne est assurée par un système de bras articulé comprenant un axe 33 parallèle à l'axe 31 monté à rotation sur le châssis du chariot et possédant une extrémité 33a recourbée qui permet la mise en place par emmanchement d'un levier 34. Un premier bras 35 est solidaire en rotation du levier 34 par l'une de ses extrémités. L'autre extrémité est susceptible d'être articulée sur une extrémité d'un second bras 36 dont la seconde extrémité est articulée à la partie arrière de la benne. Ainsi, en actionnant le levier 34 dans le sens A (figure 5BI on provoque l'ouverture de l'angle au sommet du compas que forment les bras 35 et 36 donc le soulèvement de la partie transversale arrière de la benne, donc son basculement autour de l'axe 31.The tilting maneuver of the bucket is ensured by an articulated arm system comprising an axis 33 parallel to the axis 31 rotatably mounted on the chassis of the carriage and having a curved end 33a which allows the fitting by fitting of a lever 34. A first arm 35 is integral in rotation with the lever 34 by one of its ends. The other end is capable of being articulated on one end of a second arm 36, the second end of which is articulated at the rear part of the bucket. Thus, by actuating the lever 34 in the direction A (FIG. 5BI, the angle at the top of the compass formed by the arms 35 and 36 is opened, therefore the rear transverse part of the bucket is raised, thus tilting around. of axis 31.

On notera enfin sur la figure 5B la présence d'une plaque de fermeture 37 de l'ouverture de déversement de la benne. Cette plaque 37 est rapportée sur le châssis du chariot 12 au moyen d'organes de fixation 38. Fixe par rapport au chariot,elle obture l'ouverture de déversement de la benne lorsque cette dernière n'est pas inclinée. L'inclinaison provoque un abaissement du bord antérieur du fond de la benne par rapport au bord inférieur de laplaque 37 et ces deux bords définissent la section de l'ouverture qui est variable selon l'inclinaison donnée à la benne. Par ce moyen très simple,on peut obtenir un débit de déversement sensiblement constant.Finally, note in FIG. 5B the presence of a closure plate 37 of the dumping opening of the bucket. This plate 37 is attached to the chassis of the carriage 12 by means of fixing members 38. Fixed relative to the carriage, it closes the opening of the bucket when the latter is not inclined. The inclination causes a lowering of the front edge of the bottom of the bucket relative to the lower edge of the plate 37 and these two edges define the section of the opening which is variable according to the inclination given to the bucket. By this very simple means, a substantially constant discharge rate can be obtained.

Pour procéder à l'édification des parois latérales du réservoir,on effectue des déchargements de benne successifs dans l'espace compris entre les deux coffrages préalablement équipés de l'armature adéquate. Chaque déchargement est réalisé en basculant la benne simultanément à un déplacement du chariot sur un secteur donné de console déterminé à l'avance par l'expérience en fonction du débit de versement obtenu. La quantité de béton déversée est alors vibrée par un opérateur évoluant sur la passerelle interne (voir figure 3) et la coulée se poursuit ainsi par étapes en colimaçon. Lorsque le remplissage a atteint une hauteur prédéterminée (par exemple 40 centimètres),on escamote les butées 21. On aura d'ailleurs prévu des entretoises amovibles à la partie supérieure du coffrage (non représentées sur les figures). La quantité de béton déjà mise en place suffit pour maintenir les coffrages en place à leur base. On poursuit ensuite la coulée toujours en colimaçon jusqu'à la fin.To proceed with the construction of the side walls of the tank, successive bucket unloadings are carried out in the space between the two forms previously fitted with the appropriate reinforcement. Each unloading is carried out by tilting the bucket simultaneously with a movement of the trolley on a given sector of console determined in advance by experience as a function of the payment flow obtained. The quantity of spilled concrete is then vibrated by an operator moving on the internal walkway (see Figure 3) and the pouring continues thus in spiral steps. When the filling has reached a predetermined height (for example 40 centimeters), the stops 21 are retracted. Furthermore, removable spacers will have been provided at the upper part of the formwork (not shown in the figures). The quantity of concrete already put in place is enough to keep the forms in place at their base. Then continue the casting still spiral until the end.

Le dispositif selon l'invention permet la réalisation d'un réservoir ou d'une cuve en un temps très court. Le réservoir ainsi réalisé est en outre parfaitement étanche,brut de coulée et ne nécessite aucune finition (enduit) interne ou externe. Enfin,la main-d'oeuvre nécessaire à la construction est réduite au minimum.The device according to the invention allows the realization of a tank or a tank in a very short time. The tank thus produced is also perfectly sealed, untreated and does not require any internal or external (coated) finish. Finally, the labor required for construction is reduced to a minimum.

L'invention trouve une application intéressante dans le domaine du génie civil et notamment dans la construction en béton armé de structures cylindriques.The invention finds an interesting application in the field of civil engineering and in particular in the construction of reinforced concrete of cylindrical structures.

Elle n'est pas limitée à la description qui vient d'en être donnée mais couvre au contraire toutes les variantes qui pourraient lui être apportées sans sortir de son cadre ni de son esprit. Ainsi,on peut prévoir plusieurs hauteurs de coffragescylin- driques superposées avec ou sans dalle intermédiaire.It is not limited to the description which has just been given, but on the contrary covers all the variants which could be made to it without departing from its scope or its spirit. Thus, several heights of superimposed cylindrical formwork can be provided with or without an intermediate slab.
